Technical Field

The present invention relates to a patch unit for inspection for use in image diagnosis using microwaves.

Background

As a method for examining breast cancer, mammography (mammogram) using microwaves has been proposed (see, for example, patent document 1). In mammography using microwaves, since it is not necessary to compress a breast as an examination target, a subject does not feel pain during examination. In addition, X-rays are not used in mammography using microwaves, and thus the subject is not exposed to X-rays.

In mammography with microwaves, a probe is used to scan the entire breast. At this time, in order not to generate a scan omission, a tattoo patch printed with a coordinate grid is attached to the breast. The tattoo patch includes an adhesive layer and an image-receiving layer (see, for example, patent documents 2 and 3). The coordinate grid is formed on the image receiving layer using an ink jet printer or the like.

Disclosure of Invention

Problems to be solved by the invention

In the case of using a tattoo patch as an examination patch for examining a breast, the examination patch needs to have a large area to the extent that it can cover the entire breast. Since the test patch is very thin, wrinkles are likely to be generated in the test patch. Therefore, in order to attach the patch for examination to the breast without generating wrinkles on the patch for examination, the following operations need to be repeatedly performed: the patch for examination is temporarily attached to the breast, and then only the portion of the patch for examination where wrinkles have been generated is peeled off from the breast, stretched again, and attached to the breast. In addition, in order to reduce the number of times of re-attaching the test patch, it is necessary for a plurality of persons to attach the test patch to the breast so that wrinkles do not occur in the test patch. Therefore, in mammography using an examination patch, since it takes time to attach the examination patch to the breast, it is required to improve the work efficiency of examination by reducing the operation time.

These cases are not limited to the case where the examination target is a breast, and are common to the case of other parts of the human body.

The invention aims to provide a patch unit for inspection, which can improve the work efficiency in the inspection.

Means for solving the problems

The patch unit for inspection for solving the above problems includes: a base film including a surface and a back surface which is a surface opposite to the surface; an adhesive layer on the back surface of the base film; and a support attached to the surface of the base film, the support having a shape along at least a part of an edge of the base film in a plan view facing the surface, and including a strip-shaped portion connecting 2 points facing each other at the edge with a central portion of the base film interposed therebetween.

The patch unit for inspection for solving the above problems includes: a base film including a surface and a back surface which is a surface opposite to the surface; an adhesive layer on the back surface of the base film; and a support for mounting on the surface of the base film. The support has a shape along an edge of the base film in a plan view opposite to the surface in a state where the support is attached to the surface, and includes a strip-shaped portion connecting 2 points facing each other at the edge with a central portion of the base film interposed therebetween.

According to each of the above configurations, the laminated body of the base film and the adhesive layer is supported by the support, so that a portion of the edge of the laminated body supported by the support can be held in a state of extending in accordance with the shape of the support. Therefore, an inspection practitioner who attaches the laminate to the inspection object can keep the entire laminate in a wrinkle-free state by stretching only a portion of the edge of the laminate that is not supported by the support toward the outside. This makes it possible to attach the laminate to the inspection object without generating wrinkles, and thus to suppress generation of wrinkles in the laminate attached to the inspection object. Therefore, according to the patch unit for inspection having the support, the work efficiency in the inspection can be improved.

In the patch unit for examination, the support may have: the center portion may be formed in any one of a polygonal shape surrounding the entire center portion, a polygonal line shape surrounding the center portion with a part of the edge left, a circular shape surrounding the entire center portion, and an arc shape surrounding the center portion with a part of the edge left.

According to the above configuration, the region surrounded by the support in the laminate can be held in a state stretched by the support. This can prevent wrinkles from being generated in the laminate when the laminate is attached to the inspection object.

In the patch unit for inspection described above, the support may have a fragile portion that is a portion that is more easily broken than a portion other than the fragile portion in the support. According to this configuration, the support body can be easily broken when the fragile portion is used as a trigger. This makes it easy to remove the support from the surface of the base film.

In the above-described patch unit for inspection, the fragile portion may be a pinhole. According to this configuration, the support can be broken along the pin hole.

In the above-described patch unit for inspection, the breaking strength of the portion of the support other than the fragile portion may be higher than the breaking strength of the base film, and the adhesive strength between the support and the surface may be higher than the adhesive strength between the adhesive layer and the inspection target.

According to the above configuration, when the support is broken with the weak portion as a trigger, the laminate of the base film and the adhesive layer can be broken along the boundary between the support and the base film in a plan view facing the surface of the base film. Further, the portion of the laminate body overlapping the support can be removed from the inspection object together with the support, as viewed in the thickness direction of the laminate body.

In the above-described patch unit for inspection, the fragile portion may be located at a portion including a point having a largest distance from the center of gravity of the base film among the support in a plan view opposite to the surface.

According to the above configuration, in comparison with the case where the distance between the fragile portion and the center of gravity of the base film is small, when the support is removed from the base film, generation of wrinkles in the laminated body of the base film and the adhesive layer can be suppressed, or a change in the position of the laminated body with respect to the inspection target can be suppressed.

In the patch unit for inspection, the support has a polygon having: a1 st side including a1 st point among the 1 st point, a 2 nd side including a 2 nd point among the 2 nd points, and a connecting side connecting the 1 st side and the 2 nd side, the support having a1 st corner formed by the 1 st side and the connecting side, and a 2 nd corner formed by the 2 nd side and the connecting side, inner edges of the 1 st corner and the 2 nd corner having an arc shape having a center of curvature on the base film.

According to the above configuration, since the inner edge is easily formed along the shape of the inspection object having the curved surface by forming the inner edge with the curvature, it is difficult to generate wrinkles in the laminate when the laminate of the base film and the adhesive layer surrounded by the inner edge is attached to the inspection object. In addition, by providing the inner edge with a curvature, the support body can be cut more easily from the outer edge toward the inner edge than in the case where the corner portion is formed by 2 straight lines.

In the above patch unit for inspection, the support includes the weak portion in at least one of the 1 st corner and the 2 nd corner, and the weak portion is more easily broken than a portion of the support other than the weak portion. According to this configuration, the periphery of the fragile portion is easily gripped, and a force for breaking the fragile portion is easily applied to the fragile portion, as compared with a case where the fragile portion is located in the middle of the extension of each side.

In the above patch unit for inspection, the support includes a back surface facing the base film and a surface that is a surface opposite to the back surface, and a surface roughness of the back surface of the support is larger than a surface roughness of the surface of the support.

According to the above configuration, the surface of the support having a large surface roughness is used as the back surface to be attached to the base film, whereby the contact area between the back surface of the support and the object to be bonded to the support can be increased. This can improve the adhesion between the base film and the support.

In the above patch unit for inspection, a protective layer may be further provided to cover a portion of the surface that is inside the support in a plan view opposite to the surface.

According to the above configuration, a portion exposed from the support among the surfaces of the base film is covered with the protective layer, and therefore, the portion covered with the protective layer can be kept clean before the laminated body of the base film and the adhesive layer is used for inspection.

Effects of the invention

According to the invention, the work efficiency in the inspection can be improved.

Detailed Description

An embodiment of the patch unit for inspection will be described with reference to fig. 1 to 7. The structure of the inspection patch unit, the method of using the inspection patch unit, the method of circulating the inspection patch unit, and examples will be described in order below.

[ Structure of Patch Unit for examination ]

The structure of the inspection patch unit will be described with reference to fig. 1 to 4. In the present embodiment, the patch unit for examination is used in mammography, which is an example of image diagnosis using microwaves. In the present embodiment, it is particularly preferable to use microwaves having a wavelength band of 300MHz to 300 GHz. In mammography, an examination patch unit includes a patch main body attached to a breast as an examination target.

As shown in fig. 1, the inspection patch unit 10 includes a base film 11, an adhesive layer 12, and a support 13. The base film 11 includes a surface 11F and a back surface 11R which is a surface opposite to the surface 11F. The adhesive layer 12 is located on the back surface 11R of the base film 11. The base film 11 and the adhesive layer 12 form a patch body 10A. The support 13 is mounted on the surface 11F of the base film 11.

The support 13 may be directly attached to the surface 11F of the base film 11, or may be indirectly attached to the surface 11F of the base film 11. In the present embodiment, the inspection patch unit 10 further includes an adhesive layer 14 for attaching the support 13 to the surface 11F of the base film 11. The support 13 is indirectly attached to the surface 11F of the base film 11 via the adhesive layer 14.

The base film 11 is made of synthetic resin. The base film 11 is made of, for example, urethane resin. The base film 11 may be formed of a synthetic resin other than a urethane resin as long as the following 2 conditions are satisfied. The thickness of the base film 11 may be, for example, 5 μm to 15 μm.

(Condition 1) the tensile elongation at break is 130% or more.

(Condition 2) the 100% stress at definite elongation is 10MPa or less.

"test method for Plastic-tensile Properties" according to JIS K7127: 1999(ISO 527-3:1995) -part 3: test conditions for films and sheets "and JIS K7161-1: 2014(ISO 527-1: 2012)" calculation method for plastic-tensile properties — part 1: general rule ", the tensile elongation at break is calculated. When the test piece as the object of measurement has no yield point, "tensile strain at break" defined in 3.7.2 of JIS K7161-1: 2014 was calculated as the tensile elongation at break. On the other hand, when the test piece had a yield point, "tensile breaking nominal strain" defined in 3.8.1 of the standard was calculated as the tensile breaking elongation. The tensile strain at break was calculated from the following formula (1) described in "calculation and expression of test result" of 10 "of the standard. The tensile breaking nominal strain is calculated from the following formula (2) described in "calculation and expression of test result" of 10 "of the standard.

ε＝ΔL₀/L₀The formula (1)

ε_t＝ε_y+ΔL_tL, formula (2)

In the formula (1), ε represents strain (%), and L represents₀Is the distance (mm) between the standard lines of the test piece, Delta L₀The increase (mm) in the distance between the standard lines of the test piece. In addition, in the formula (2), ε_tIs the nominal strain (%), ε_yYield strain (%), L initial inter-jig distance (mm), and Δ L_tIs the increase in distance (mm) between the clamps from the yield point.

"test method for Plastic-tensile Properties" according to JIS K7127: 1999(ISO 527-3:1995) -part 3: test conditions for films and sheets "in JIS K7161-1: 2014(ISO 527-1: 2012)" calculation method for plastic-tensile properties "section 1: in "tensile stress at x% strain" defined in 3.6.3 of general rule, "the stress at 100% stress at definite elongation is calculated as the stress at which the strain reaches a predetermined value (100%). The 100% strain tensile stress was calculated from the following formula (3) described in "calculation and expression of test result" of 10 "of the standard.

Sigma F/a · formula (3)

In the formula (3), σ is the stress (MPa), F is the magnitude of the measured force (N), and a is the initial cross-sectional area (mm) of the test piece²)。

The adhesive layer 12 is made of synthetic resin, as with the base film 11. The adhesive layer 12 is made of, for example, a urethane resin. In the patch main body 10A which is a laminate of the base film 11 and the adhesive layer 12, the adhesive layer 12 may be formed of a synthetic resin other than a urethane resin as long as the following condition 3 is satisfied in addition to the above-described conditions 1 and 2. The thickness of the adhesive layer 12 may be, for example, 5 μm or more and 25 μm or less.

(Condition 3) the moisture permeability specified in JIS Z0208 is 750g/m under the conditions of 40 ℃ and 90% relative humidity²Day or more.

The support body 13 may be made of paper or synthetic resin. The support 13 preferably has higher rigidity than the patch main body 10A. On the other hand, in the case of applying the patch unit for examination 10 to a curved surface such as a breast, the support 13 preferably has flexibility capable of bending along the curved surface. In the case where the supporting body 13 is made of paper, the rigidity and flexibility of the supporting body 13 can be adjusted according to the unit weight of the paper. In the case where the support 13 is made of synthetic resin, the rigidity and flexibility of the support 13 can be adjusted by the kind of synthetic resin and the thickness of the support 13.

The inspection patch unit 10 further includes a protective film 15. The protective film 15 is laminated to the back surface 11R of the base film 11 so as to be peelable. The protective film 15 covers the entire base film 11 as viewed from the direction opposite to the protective film 15. The protective film 15 is preferably made of a transparent or translucent synthetic resin. The protective film 15 is composed of, for example, a base film and a release layer. The release layer is laminated on the base material film. In the protective film 15, the release layer is in contact with the adhesive layer 12. The substrate film may be, for example, a polyethylene terephthalate (PET) film or the like. The release layer may be, for example, a layer made of silicone resin. The protective film 15 may be formed only of the base film, and a surface of the base film that is in contact with the base film 11 may be processed to improve peelability.

As shown in fig. 2, the support 13 has a shape along the edge 11E of the base film 11 in a plan view opposite to the surface 11F of the base film 11. The support 13 includes a strip-shaped portion connecting 2 points facing each other at the edge 11E with the central portion 11M of the base film 11 therebetween. The central portion 11M of the base film 11 has an area half of the area of the surface 11F and has an edge of a shape similar to the edge 11E of the base film 11, and the distance from the edge 11E of the base film 11 is equal between any points on the edge of the central portion 11M.

In the present embodiment, the support 13 has a polygonal shape surrounding the entire central portion 11M. In detail, the support 13 is a closed-loop rectangular frame. The support 13 is located at the entire edge 11E of the base film 11. In the present embodiment, when a pair of sides facing each other in the vertical direction of the sheet surface is defined as the 1 st side 13b1 and the 2 nd side 13b2, the 2 sides facing each other in the horizontal direction of the sheet surface is defined as the connecting side 13b3 connecting the 1 st side 13b1 and the 2 nd side 13b 2. The 1 st edge 13b1 is an edge including the 1 st point P1 which is one of the 2 points, and the 2 nd edge 13b2 is an edge including the 2 nd point P2 which is the other of the 2 points. As described above, the support 13 has a rectangular frame shape including the 1 st side 13b1, the 2 nd side 13b2, and the connecting side 13b 3. As in the present embodiment, when the 1 st point P1 and the 2 nd point P2 are set, the strip-shaped portion may include a part of the 1 st side 13b1, a part of the 2 nd side 13b2, and one connecting side 13b 3.

By supporting the patch main body 10A by the support 13, a portion supported by the support 13 among the edges of the patch main body 10A can be held in a state of extending in accordance with the shape of the support 13. Therefore, the examiner who attaches the patch main body 10A to the breast can keep the entire patch main body 10A in a wrinkle-free state by stretching only the portion of the edge of the patch main body 10A that is not supported by the support 13 toward the outside. This makes it possible to attach the patch main body 10A to the breast without generating wrinkles, and thus to suppress the generation of wrinkles in the patch main body 10A attached to the breast. Therefore, according to the patch unit for inspection 10 having the support 13, the work efficiency in the inspection can be improved. The examination executor is, for example, a doctor or an examination technician.

The base film 11 has a coordinate grid 16 for guiding the scanning position of the examination object. In a plan view opposite to the surface 11F of the base film 11, the coordinate grid 16 is located within an area surrounded by the support 13. The coordinate grid 16 includes a plurality of 1 st grid lines 16 a. Each 1 st grid line 16a extends along the scanning direction, and a plurality of 1 st grid lines 16a are arranged along an arrangement direction perpendicular to the scanning direction. In the present embodiment, the vertical direction on the paper surface is the scanning direction, and the horizontal direction on the paper surface is the arrangement direction. In mammography, the scanning direction is a direction in which an examination practitioner scans an examination object with a probe.

The coordinate grid 16 further includes a plurality of 2 nd grid lines 16b extending along the arrangement direction and side by side along the scanning direction. The plurality of 2 nd mesh lines 16b form a square lattice together with the plurality of 1 st mesh lines 16a as viewed from a direction opposite to the surface 11F of the base film 11.

The coordinate grid 16 may be printed on the back side 11R of the base film 11 using ink. As the ink for printing the coordinate grid 16, any ink capable of printing the base film 11 may be used.

In the inspection patch unit 10, the total light transmittance specified in JIS K7361-1 is preferably 50% or more in the portion other than the coordinate grid 16 in the patch main body 10A. Thus, when the patch unit for examination 10 is attached to the breast, the position of the patch unit for examination 10 with respect to the breast can be adjusted while visually checking the position of the coordinate grid 16 with respect to the breast. In addition, if the total light transmittance of the patch unit for examination 10 is 50% or more, the position of a mole or spot on the breast can be determined by visual observation or a camera through the base film 11 and the adhesive layer 12 after attaching the base film 11 and the adhesive layer 12 on the breast. The location of the nevi or spots in the breast is important in determining the location of the lesion in the breast, since the location of the nevi or spots in the breast does not change.

In contrast, in the support 13, the total light transmittance specified in JIS K7361-1 is preferably lower than the total light transmittance in the portion other than the coordinate grid 16 in the patch main body 10A. The support 13 is preferably translucent or opaque. Thus, the boundary between the patch main body 10A and the support 13 is clear, compared to the case where the support 13 has the same degree of permeability as the patch main body 10A. Therefore, when the support 13 is removed from the test patch unit 10, it is easy to determine whether or not the patch main body 10A can be broken along the support 13. Thus, when the support 13 is removed from the test patch unit 10, the boundary between the patch main body 10A and the support 13 can be prevented from being cut further inside.

The support 13 includes a fragile portion 13 a. The fragile portion 13a is a portion that is more easily broken than portions other than the fragile portion 13a in the support body 13. The fragile portion 13a is a portion having a lower mechanical strength than portions of the support body 13 other than the fragile portion 13 a. By providing the support 13 with the fragile portion 13a, the support 13 can be broken in the fragile portion 13 a. Therefore, the support 13 can be easily removed from the surface 11F of the base film 11 when the fragile portion 13a is broken.

The breaking strength of the portion of the support 13 other than the fragile portion 13a is higher than that of the base film 11, and the adhesion strength between the support 13 and the surface 11F of the base film 11 is higher than that with the inspection object. Therefore, when the support 13 is broken with the fragile portion 13a as a trigger, the patch body 10A can be broken along the boundary between the support 13 and the base film 11 in a plan view facing the surface 11F of the base film 11. Further, when viewed from the thickness direction of the patch main body 10A, that is, when viewed from a line of sight facing the surface 11F of the base film 11, the portion of the patch main body 10A overlapping the support 13 can be removed from the breast together with the support 13.

In the base film 11, the breaking strength prescribed in JIS K7127 is preferably 35N/25mm or less, more preferably 25N/25mm or less. When the breaking strength of the base film 11 is included in the range of 35N/25mm or less, the patch body 10A is easily broken together with the support 13.

The fragile portion 13a is preferably located at a portion including a point having the largest distance from the center of gravity of the base film 11 among the support 13 in a plan view opposite to the surface 11F of the base film 11. Accordingly, when the support 13 is removed from the base film 11, the generation of wrinkles in the base film 11 or the change in the position of the base film 11 with respect to the breast can be suppressed, as compared with the case where the distance between the fragile portion 13a and the center of gravity of the base film 11 is small.

In the present embodiment, the patch main body 10A has a rectangular shape and the support 13 has a rectangular frame shape when viewed from a direction facing the surface 11F of the base film 11. Therefore, in the support 13, the portions including the points having the largest distance from the center of gravity of the base film 11 are the respective corner portions of the support 13. The support 13 has: a1 st corner 13c1 perpendicular to the 1 st edge 13b1 and the connecting edge 13b3, and a 2 nd corner 13c2 perpendicular to the 2 nd edge 13b2 and the connecting edge 13b 3. The support 13 preferably includes a fragile portion 13a in at least one of the 1 st corner portion 13c1 and the 2 nd corner portion 13c 2. In this case, as compared with the case where the fragile portion 13a is positioned in the middle of the extension of the sides 13b1, 13b2, and 13b3, the periphery of the fragile portion 13a is easily gripped, and a force for breaking the fragile portion 13a is easily applied to the fragile portion 13 a.

In addition, in the present embodiment, the fragile portion 13a may be located in both the 1 st corner 13c1 and the 2 nd corner 13c 2. Therefore, the degree of freedom of the manner of attaching the test patch unit 10 to the test object is improved as compared with the case where the support 13 includes only 1 fragile portion 13 a. In particular, when the examination target includes 2 regions having bilateral symmetry, such as breasts, the effect of the weak portion 13a can be obtained in both the left breast and the right breast by providing the weak portion 13a in both the 1 st corner portion 13c1 and the 2 nd corner portion 13c 2.

Fig. 3 is an enlarged view showing the planar structure of the fragile portion 13a located at the 2 nd corner portion 13c 2.

As shown in fig. 3, the fragile portion 13a is a pinhole 13 am. Therefore, the support 13 can be broken along the pin hole 13 am. The support body 13 includes an outer edge 13e1 and an inner edge 13e 2. The inner edge 13e2 is a portion that is less distant from the central portion 11M of the base film 11 than the outer edge 13e 1. The pinhole 13am includes an arrow shape from the outer edge 13e1 toward the inner edge 13e 2. Therefore, when a force to break the fragile portion 13a from the outer edge 13e1 toward the inner edge 13e2 is applied to the support body 13, the support body 13 is easily broken from the outer edge 13e1 toward the inner edge 13e2, as compared with the case where the fragile portion 13a is formed only of linear pinholes.

In a plan view opposite to the surface 11F of the base film 11, the inner edges of the corner portions 13c1 and 13c2 of the support 13 have an arc shape having a center of curvature in the base film 11. In other words, a portion of the inner edge 13e2 corresponding to each of the corner portions 13c1 and 13c2 has an arc shape having a center of curvature in the base film 11. Therefore, the inner edge is easily formed along the breast shape having the curved surface, and when the patch main body 10A surrounded by the inner edge 13e2 is attached to the breast, wrinkles are less likely to be generated in the patch main body 10A. In addition, by providing the inner edge with a curvature, the support body 13 is easily cut from the outer edge 13e1 toward the inner edge 13e2, as compared with the case where the corner portions 13c1, 13c2 are formed by 2 straight lines.

In the present embodiment, a portion of the outer edge 13e1 corresponding to each of the corner portions 13c1 and 13c2 has an arc shape having a center of curvature on the base film 11. Thus, by making the outer edge 13e1 have a curvature, the skin of the subject can be suppressed from being scratched by the corners 13c1, 13c 2.

Fig. 4 is an enlarged view showing a part of the cross-sectional structure of the patch unit for inspection 10 of fig. 1.

As shown in fig. 4, the support 13 includes a back surface 13R and a surface 13F. The back surface 13R of the support 13 is a surface facing the base film 11. The front surface 13F of the support 13 is the surface opposite to the back surface 13R. The surface roughness of the back surface 13R of the support 13 is larger than the surface roughness of the surface 13F of the support 13.

Therefore, by setting the surface with the larger surface roughness among the surfaces of the support 13 as the back surface 13R attached to the base film 11, the contact area between the back surface 13R of the support 13 and the adhesion target of the support 13 can be increased. This can improve the adhesion between the base film 11 and the support 13. In the present embodiment, since the support 13 is bonded to the base film 11 via the adhesive layer 14, the contact area between the support 13 and the adhesive layer 14 can be increased. This makes it difficult for peeling to occur at the interface between the support 13 and the adhesive layer 14, and as a result, the adhesiveness of the support 13 to the base film 11 is improved.

The surface roughness of the front surface 13F and the back surface 13R of the support 13 can be evaluated, for example, according to the arithmetic average roughness Ra, the maximum height Rz, the maximum peak height Rp, the maximum valley depth Rv, and the like specified in JIS B0601.

The rigidity of the support 13 may be lower than that of the protective film 15 or higher than that of the protective film 15. When the rigidity of the support 13 is lower than that of the protective film 15, when the laminated body of the adhesive layer 12, the base film 11, and the support 13 is attached to the breast and curved in accordance with the curved surface of the breast, the laminated body is more likely to curve in accordance with the shape of the breast. In addition, in the case where the rigidity of the support 13 is higher than the rigidity of the protective film 15, the protective film 15 is easily peeled off from the adhesive layer 12 when the patch unit for inspection 10 is used, and wrinkles can be suppressed from being generated in the patch main body 10A from after the protective film 15 is peeled off until the adhesive layer 12 is attached to the breast.

[ method of Using Patch Unit for examination ]

A method of using the inspection patch unit 10 will be described with reference to fig. 5 to 7.

As shown in fig. 5, when the inspection patch unit 10 is used, first, the user peels the protective film 15 from the adhesive layer 12. In the patch unit for examination 10, a patch main body 10A formed of a base film 11 and an adhesive layer 12 is used for breast examination.

Next, as shown in fig. 6, the adhesive layer 12 is attached to the breast B of the subject S. At this time, for example, the test practitioner holds one side of the pair of sides of the support 13 and a part of the patch main body 10A overlapping the one side simultaneously with one hand, and holds the other side and a part of the patch main body 10A overlapping the one side simultaneously with the other hand. The deformation of the patch main body 10A is restricted by the support 13 so that the shape thereof does not change, and furthermore, the test practitioner applies a force to the patch main body 10A in a direction in which the pair of sides are away from each other, thereby suppressing the occurrence of wrinkles in the patch main body 10A.

As described above, the patch body 10A is very thin and satisfies the conditions 1 and 2, and thus can be extended very well with only a small force applied to the patch body 10A. Therefore, in order to attach the patch main body 10A having a rectangular shape and a large area covering the entire breast B to the breast B without wrinkles, it is necessary to stretch 4 sides constituting the edge of the patch main body 10A outward. That is, two or more examination executors are required to attach the patch main body 10A to the breast B.

In this regard, according to the patch unit for inspection 10 of the present embodiment, since the patch main body 10A is supported in a state where deformation is restricted by the support 13, even if the patch main body 10A is attached to the breast B by one inspection practitioner, generation of wrinkles in the patch main body 10A can be suppressed at the time of attaching the patch main body 10A. This can reduce the number of examiners, and therefore, the patch unit for examination 10 can improve the work efficiency in mammography. In addition, according to the patch unit for examination 10 of the present embodiment, the patch main body 10A can be attached to the breast B without generating wrinkles in the patch main body 10A. This can reduce the time taken to re-attach the patch main body 10A to the wrinkled portion. This may also improve the efficiency of the work in mammography.

When the patch main body 10A is attached to the breast B, one of the corners 13c1 and 13c2 having the fragile portion 13a is preferably located closer to the midline of the subject S than the corner other than the corner and near the head. This makes it possible to position the fragile portion 13a on the rib of the subject S, and therefore, when the support body 13 is broken with the fragile portion 13a as a trigger, a force is easily applied to the fragile portion 13 a.

As shown in fig. 7, the support 13 is broken at the fragile portion 13a, and the support 13 is removed from the patch body 10A together with a part of the patch body 10A. As described above, the patch body 10A can be extended very well with only a small force applied thereto. Therefore, it is difficult to remove only the support 13 from the patch main body 10A without breaking the support 13 and attaching the patch main body 10A to the breast without wrinkles.

In this regard, according to the inspection patch unit 10 of the present embodiment, the support 13 is broken with the fragile portion 13a as a trigger, and then, when viewed from the direction facing the surface 11F of the base film 11, the patch body 10A can be broken along the support 13 at the boundary between the support 13 and the patch body 10A. This can prevent the occurrence of wrinkles in the patch main body 10A when the support 13 is detached from the patch main body 10A.

[ circulation method of Patch Unit for examination ]

The patch unit for inspection 10 can be circulated in a state where the protective film 15, the adhesive layer 12, the base film 11, and the support 13 are integrated. Alternatively, the test patch unit 10 may be configured to be circulated in a state where the patch main body 10A with the protective film 15 is separated from the support 13. In this case, the patch body 10A preferably includes a separation film covering the base film 11. In the case where the support 13 is attached to the patch main body 10A via the adhesive layer 14, the support 13 preferably has the adhesive layer 14. When the support 13 has the adhesive layer 14 and is circulated in a state where the support 13 is separated from the patch main body 10A with the protective film 15, the support 13 preferably has a protective film for protecting the adhesive layer 14 laminated on the support 13.

That is, the inspection patch unit 10 may be as follows. The inspection patch unit 10 includes: a base film 11, an adhesive layer 12, and a support 13 for mounting on a surface 11F of the base film 11. In a state where the support 13 is attached to the surface 11F of the base film 11, the support 13 has a shape along the edge 11E of the base film 11 in a plan view opposing the surface 11F, and has a strip-like portion connecting 2 points opposing each other at the edge 11E with the central portion 11M of the base film 11 therebetween.

Examples

Examples and comparative examples of the patch unit for inspection will be described with reference to table 1.

In each of examples 1 to 5 and comparative example 1, a patch main body with a protective film common to them was prepared by the method described below.

[ Patch body with protective film ]

A PET film (manufactured by imperial レフィルム, inc., セラピール) having a thickness of 75 μm and having a silicone coating on one side was prepared as a protective film (セラピール is a registered trademark). Then, 1 part of a curing agent (トーヨーケム (strain) or T-501B) was added to 100 parts of a urethane adhesive (トーヨーケム (strain) or サイアバイン SP-205), and the resulting liquid was coated on the silicone-coated surface of the PET film, thereby forming an adhesive layer (サイアバイン is a registered trademark) having a thickness of 15 μm. Subsequently, a biaxially oriented polypropylene (OPP) film (manufactured by フタムラ chemical Co., Ltd., FOR-MP) having a thickness of 40 μm was prepared as a separation film. Then, an aqueous urethane resin (WS-6021, manufactured by Mitsui chemical Co., Ltd.) was coated on the separation membrane to form a base membrane having a thickness of 15 μm. Further, a coordinate grid for inspection is printed on the back surface of the base film. Next, an adhesive layer formed by the above coating was attached to the back surface of the printed surface as a base film, and then the separation film was peeled off from the base film, thereby obtaining a patch main body with a protective film.

Comparative example 1

The test patch unit of comparative example 1 was obtained by molding the patch main body with the protective film into a rectangular shape having a longitudinal length of 220mm and a lateral length of 240 mm.

[ example 1]

In the same manner as in comparative example 1, a patch body with a protective film was prepared. Next, a support having a shape along 3 sides except 1 side extending in the transverse direction among the edges of the patch main body with the protective film was prepared. In the support, the length of each side in the direction perpendicular to the extending direction, i.e., the width, was set to 10 mm. In the material forming the support, a basis weight of 260g/m was used²The paper material of (manufactured by Takara Shuzo, インバーコート M-FS). The patch unit for inspection of example 1 was obtained by attaching a support to the surface of the base film.

[ example 2]

An inspection patch unit of example 2 was obtained in the same manner as in example 1 except that a rectangular frame-shaped support having edges along the patch main body with a protective film was prepared in example 1.

[ example 3]

An inspection patch unit of example 3 was obtained in the same manner as in example 2, except that a notch was formed in 1 corner of the support so as to be recessed from the outer edge toward the inner edge of the support in example 2.

[ example 4]

An inspection patch unit of example 4 was obtained in the same manner as in example 2, except that pinholes were formed from the outer edge toward the inner edge of the support at 1 corner of the support in example 2.

[ example 5]

An inspection patch unit of example 5 was obtained in the same manner as in example 4, except that the patch main body with the protective film was formed into a circular shape having a radius of 140mm and formed into a ring-shaped support in example 4.

[ evaluation method ]

The patch units for examination of examples 1 to 5 and the patch unit for examination of comparative example 1 were attached to the breast of a model for breast cancer palpation training (manufactured by ltd. タナック) by 1 experimenter. In examples 1 to 5, the protective film was removed from the adhesive layer, and then the patch main body was attached to the breast cancer palpation training mold together with the support. On the other hand, in comparative example 1, the protective film was removed from the adhesive layer, and the separation film was removed from the base film, and then the patch body was attached to a breast cancer palpation training model. At this time, the following 3 items were evaluated.

(item 1) the edge of the patch body can be uniformly stretched

(item 2) the patch main body may be attached to the breast in such a manner that the patch main body does not generate wrinkles

(item 3) after the patch body is attached, the support can be removed from the patch body

In item 1, whether or not the edge of the patch main body can be uniformly stretched was evaluated according to the following 2 grades when the patch main body was attached to the breast.

In the entire edge of the patch body, the patch body can be uniformly stretched

X in at least a part of the edge of the patch main body, the patch main body cannot be stretched

In item 2, whether or not the patch main body wrinkles when the patch main body is attached to the breast was evaluated according to the following 3 grades.

Excellent patch body without wrinkles

No wrinkles were produced in the area for inspection in the patch body

Wrinkles are generated in the region for inspection in the x patch main body

In item 3, after the patch main body was attached to the breast, whether or not the support could be removed from the patch main body was evaluated according to the following 2 ranks.

O. the support can be removed while keeping the patch main body attached to the breast

When the support is removed from the patch main body, the patch main body cannot be kept attached to the breast

[ evaluation results ]

The patch units for inspection of examples 1 to 5 and the patch unit for inspection of comparative example 1 were subjected to the evaluations of items 1 to 3 described above, and the results are shown in table 1 below.

[ Table 1]

	Item 1	Item 2	Item 3
				Comparative example 1	×	×	-
Example 1	○	○	○
				Example 2	○	◎	×
Example 3	○	◎	○
				Example 4	○	◎	○
Example 5	○	◎	○

As shown in table 1, when the patch unit for inspection of comparative example 1 was used, the edge of the patch body could not be uniformly stretched by one experimenter. Therefore, when the patch unit for inspection of comparative example 1 was used, the patch main body could not be attached to the breast without generating wrinkles in the patch main body.

In the case of using the patch unit for inspection of example 1, since 3 sides out of the edges of the patch main body are in a state of being stretched by the support, one experimenter can uniformly stretch the edges of the patch main body by stretching the remaining one side. Thus, when the patch unit for examination of example 1 was used, even if wrinkles were generated in the peripheral portion of the patch main body, the patch main body could be attached to the breast without generating wrinkles in the region for examination. That is, according to embodiment 1, it can be confirmed that: the patch main body can be attached to the breast in a state where the patch main body is not wrinkled to such an extent that no obstruction is generated during examination. In addition, in a state where the patch main body is attached to the breast, the patch main body may be broken along the support with a boundary between the open end of the support and the patch main body as a trigger. Thus, according to the test patch of example 1, the support can be removed from the patch main body while keeping the patch main body attached to the breast.

In the case of using the patch for inspection of example 2, since the entire edge of the patch main body is in a state of being stretched by the support, the edge of the patch main body can be uniformly stretched. Thus, when the patch unit for examination of example 2 is used, the patch main body can be attached to the breast without generating wrinkles in the patch main body. On the other hand, it was confirmed that: since the support does not have a chance to break the support, when a force for removing the support from the patch main body is applied to the support, a part of the patch main body is wrinkled or the other part of the patch main body is raised from the breast. Thus, according to the patch unit for examination of example 2, the support cannot be removed from the patch main body while keeping the patch main body attached to the breast.

In the case of using the patch unit for inspection of example 3, since the entire edge of the patch main body is in a state of being stretched by the support, the edge of the patch main body can be uniformly stretched. Thus, when the patch unit for examination of example 3 is used, the patch main body can be attached to the breast without generating wrinkles in the patch main body. In the patch unit for inspection of example 3, since the support has the incision, the support can be broken at the moment of incision, and a part of the portion of the patch main body to which the support is attached can be broken together with the support. Thus, by breaking the patch main body along the boundary between the patch main body and the support, the support can be removed from the patch main body while maintaining the state in which the patch main body is attached to the breast.

In the case of using the patch unit for inspection of example 4, since the entire edge of the patch main body is stretched by the support, the edge of the patch main body can be uniformly stretched. Thus, when the patch unit for inspection of test example 4 was used, the patch main body could be attached to the breast without wrinkles occurring in the patch main body. In the patch unit for inspection of example 4, since the support has the needle hole, the support can be broken with the needle hole as a trigger, and a part of the portion of the patch main body to which the support is attached can be broken together with the support. Thus, by breaking the patch main body along the boundary between the patch main body and the support, the support can be removed from the patch main body while maintaining the state in which the patch main body is attached to the breast.

In the case of using the test patch of example 5, the same results as those in the case of using the test patch of example 4 were obtained.

As described above, according to one embodiment of the patch for inspection, the following effects can be obtained.

(1) By supporting the patch main body 10A by the support 13, a portion supported by the support 13 among the edges of the patch main body 10A can be held in a state of extending in accordance with the shape of the support 13. Therefore, the examiner who attaches the patch main body 10A to the breast B can keep the entire patch main body 10A in a wrinkle-free state by stretching only the portion of the edge of the patch main body 10A that is not supported by the support 13 toward the outside. This makes it possible to attach the patch main body 10A to the breast B without wrinkles, and thus wrinkles can be prevented from occurring in the patch main body 10A attached to the breast B. Therefore, according to the patch unit for inspection 10 having the support 13, the work efficiency in the inspection can be improved.

(2) The region surrounded by the support 13 in the patch main body 10A can be held in a state stretched by the support 13. This can prevent wrinkles from being generated in the patch main body 10A when the patch main body 10A is attached to the breast B.

(3) The support body 13 is easily broken when the fragile portion 13a is used as a trigger. This makes it easy to remove the support 13 from the surface 11F of the base film 11.

(4) The support 13 can be broken along the pin hole 13 am.

(5) When a force to break the fragile portion 13a from the outer edge 13e1 toward the inner edge 13e2 is applied to the support 13, the support 13 is easily broken from the outer edge 13e1 toward the inner edge 13e2, as compared with the case where the fragile portion 13a is formed only of linear pinholes.

(6) When the support 13 is broken with the fragile portion 13a as a trigger, the patch body 10A can be broken along the boundary between the support 13 and the base film 11 in a plan view facing the surface 11F of the base film 11. Further, the portion of the patch main body 10A overlapping the support 13 may be removed from the breast B together with the support 13, as viewed from the line of sight opposite to the surface 11F of the base film 11.

(7) Compared to the case where the distance between the fragile portion 13a and the center of gravity of the base film 11 is small, when the support 13 is removed from the base film 11, the occurrence of wrinkles in the patch main body 10A or the change in the position of the patch main body 10A with respect to the breast B can be suppressed.

(8) Since the inner edge is easily formed to follow the shape of the breast B having a curved surface by forming the inner edge with a curvature, it is difficult to form wrinkles in the patch main body 10A when the patch main body 10A surrounded by the inner edge is attached to the breast B.

(9) As compared with the case where the fragile portion 13a is positioned on the way of each side extension, the periphery of the fragile portion 13a is easily gripped, and a force for breaking the fragile portion 13a is easily applied to the fragile portion 13 a.

(10) By setting the surface of the support 13 having a large surface roughness as the back surface 13R attached to the base film 11, the contact area between the back surface 13R of the support 13 and the adhesion target of the support 13 can be increased. This can improve the adhesion between the base film 11 and the support 13.

The above embodiment may be modified as follows.

[ support ]

At least one of the outer edge 13e1 and the inner edge 13e2 of the support body 13 may have no curvature in each corner. For example, in at least one of the outer edge 13e1 and the inner edge 13e2, each corner may be formed by 2 straight lines. Alternatively, at least one of the outer edge 13e1 and the inner edge 13e2 may also include both a corner formed by 2 straight lines and a corner having curvature. Even in this case, the effect based on (1) above can be obtained as long as the patch unit for inspection 10 has the support 13.

The surface roughness of the back surface 13R of the support 13 may be equal to or less than the surface roughness of the front surface 13F. Even in this case, the effect based on (1) above can be obtained as long as the patch unit for inspection 10 has the support 13.

As shown in fig. 8, the support body 13A may also have a notch 13ak recessed from the outer edge 13e1 toward the inner edge 13e2 of the support body 13 instead of the pinhole 13am as the weak portion 13A. Even in this case, the effect according to (3) above can be obtained.

As shown in fig. 9, the support 13B may have a polygonal line shape surrounding the central portion 11M with a part of the edge 11E of the base film 11 left. For example, among the edges of the patch main body 10A having a rectangular shape, it may have a shape along a pair of sides opposing each other and 1 side connecting the pair of sides. That is, the support 13B may include only the 1 st side 13B1, the 2 nd side 13B2 opposite to the 1 st side 13B1, and the connecting side 13B3 connecting the 1 st side 13B1 and the 2 nd side 13B 2. Even in this case, the effect based on (2) above can be obtained.

In this case, the patch body 10A may be broken at the end of the 1 st side 13B1 not connected to the connecting side 13B3 or at the end of the 2 nd side 13B2 not connected to the connecting side 13B 3. Therefore, even if the support 13B does not have the fragile portion 13a, the support 13B can be detached from the patch main body 10A in a state where the patch main body 10A is attached to the breast B. The support 13B may have the fragile portion 13 a.

As shown in fig. 10, the support 13C may have a circular shape surrounding the entire central portion 11M of the base film 11. For example, the patch body 10A may have a circular shape, and the support 13C may have a circular ring shape along the edge of the patch body 10A 1. When the support 13C has an annular shape, the support 13C may have a closed ring shape as shown in fig. 10, or may have an open ring shape, that is, an arc shape in which a part of the edge 11E of the base film 11 is left to surround the central portion. Even in this case, the effect based on (2) above can be obtained.

The rigidity of the support 13 is preferably higher than that of the patch main body 10A, but the rigidity of the support 13 may be equal to or lower than that of the patch main body 10A. Even in this case, the effect (1) can be obtained by supporting the patch main body 10A by the support 13 along the edge 11E of the base film 11.

[ friable part ]

As shown in fig. 11, in the case where the support 13 has a plurality of weak portions 13a, the weak portion 13a may be located at each of four corners of the support 13. In addition, as shown in fig. 11, in the case where the 1 st side 13b1 and the 2 nd side 13b2 are longer than the connecting side 13b3, the support body 13 may have the weak portion 13a at least one of the way the 1 st side 13b1 extends and the way the 2 nd side 13b2 extends. The fragile portion 13a located on the way of the 1 st side 13b1 extending is closer to the corner of the support body 13 than the central portion of the 1 st side 13b1 in the extending direction of the 1 st side 13b 1. In addition, the fragile portion 13a located on the way in which the 2 nd side 13b2 extends is closer to the corner of the support body 13 than the central portion of the 2 nd side 13b2 in the extending direction of the 2 nd side 13b 2.

In the example shown in fig. 11, the fragile portion 13a is located at each of four corners of the support body 13, and each 2 fragile portions 13a are respectively located in each of the 1 st side 13b1 and the 2 nd side 13b 2. In the extending direction of the 1 st side 13b1, the 2 fragile portions 13a located at the 1 st side 13b1 are located at different corners from each other among the corners of the support body 13 with respect to the central portion of the 1 st side 13b 1. In the extending direction of the 2 nd side 13b2, the 2 fragile portions 13a located at the 2 nd side 13b2 are located at different corners from each other among the corners of the support body 13 with respect to the central portion of the 2 nd side 13b 2.

Since the breast B to which the patch main body 10A is attached has a bowl shape, when the patch main body 10A to which the support 13 is attached to the breast B, wrinkles are easily generated in the patch main body 10A at the four corners of the support 13.

For example, before the patch main body 10A is attached to the breast B, a portion of the support 13 sandwiched between the fragile portion 13a located at the four corners and the fragile portion 13a located on the way of each of the sides 13B1, 13B2 may be removed from the support 13. Thereby, a part of the support 13 is no longer located at the four corners of the base film 11, and hence the flexibility at the four corners of the base film 11 and the followability to the breast can be improved. Therefore, generation of wrinkles at the four corners of the base film 11 can be suppressed.

In addition, for example, after the patch main body 10A is attached to the breast B, a portion of the support 13 sandwiched between the fragile portion 13a located at the four corners and the fragile portion 13a located in the middle of each of the sides 13B1, 13B2 may be removed from the support 13. In the portion of the base film 11 where wrinkles occur, it is difficult to remove the support 13 from the base film 11, compared to the portion of the base film 11 where wrinkles do not occur. In this regard, a part of the support 13 located at the four corners of the base film 11 can be separated from the other part of the support 13, and therefore, the support 13 is easily removed from the base film 11 as compared with the case where 1 support 13 is removed from the base film 11 as a whole.

The support body 13 may include a fragile portion 13a located on the way of the extending connecting side 13b 3.

In the case where the support body 13 has a plurality of weak portions 13a, the plurality of weak portions 13a may include a weak portion 13a formed by the pinhole 13am and a weak portion 13a formed by the slit 13 ak.

The portion of the support 13 where the fragile portion 13a is located may not be a portion including a point having the largest distance from the center of gravity of the base film 11. Even in this case, the effect according to (3) above can be obtained.

The fragile portion 13a may be located only at one of the 1 st corner 13c1 and the 2 nd corner 13c 2. Even in this case, the effect according to (3) above can be obtained.

The pinhole 13am may be linear. Even in this case, the effect (3) can be obtained as long as the support 13 can be broken at the moment of the pinhole 13 am.

The support 13 may not include the fragile portion 13 a. Even in this case, the effect based on (1) above can be obtained. In this case, the breast B may be examined with the support 13 attached to the patch main body 10A, or the breast B may be examined after the support 13 is removed from the patch main body 10A.

[ adhesive layer ]

In the inspection patch unit 10, when the support 13 is bonded to the base film 11 by the adhesiveness of the base film 11, the adhesive layer 14 for bonding the support 13 to the base film 11 may not be provided. Even in this case, the surface roughness of the back surface 13R of the support 13 is preferably larger than the surface roughness of the surface 13F of the support 13. This can improve the adhesion between the support 13 and the base film 11, as compared with the case where the surface 13F of the support 13 is bonded to the base film 11.

[ coordinate grid ]

The coordinate grid 16 may have a shape other than a square lattice in a plan view opposite to the surface 11F of the base film 11. For example, the coordinate grid 16 may be made up of a plurality of concentric circles having different diameters. That is, the coordinate grid 16 may be a grid corresponding to polar coordinates. In short, the coordinate grid 16 may have a shape that can guide the direction or position of the probe for scanning, in a state where it is attached to the breast B.

The base film 11 is not limited to the coordinate grid 16, and may have a scan index of another shape such as a shape extending in 1 direction. For example, the scan index may be a position to be scanned guided by the probe or a direction of scanning.

The coordinate grid 16 may not be formed by printing. For example, the coordinate grid 16 may be formed by a concave portion or a convex portion of the base film 11.

[ base film ]

As long as the base film 11 included in the inspection patch unit 10 satisfies the above conditions 1 and 2, the synthetic resin used to form the base film 11 may be a resin other than a urethane resin. For example, the synthetic resin used to form the base film 11 may be EVA resin.

The base film 11 may not satisfy at least one of the above conditions 1 and 2. Even in this case, the effect (1) can be obtained if the inspection patch unit 10 includes the support 13 attached to the base film 11.

The breaking strength of the support 13 other than the fragile portion 13a may be equal to or less than the breaking strength of the base film 11. In this case, when the support 13 is broken in the fragile portion 13a, at least a part of the fragile portion 13a can be removed from the patch main body 10A. The adhesion strength between the support 13 and the surface 11F of the base film 11 may be equal to or less than the adhesion strength between the adhesive layer 12 and the breast B. In this case, the support 13 broken in the fragile portion 13a is easily peeled off from the base film 11.

[ Patch main body ]

The patch main body 10A may not satisfy the condition 3. Even in this case, the effect (1) can be obtained if the inspection patch unit 10 includes the support 13 attached to the base film 11.

[ protective film ]

The protective film 15 may be omitted. Even in this case, the effect (1) can be obtained if the inspection patch unit 10 includes the support 13 attached to the base film 11.

[ protective layer ]

Referring to fig. 12 and 13, the inspection patch unit 10 may further include a protective layer covering the surface 11F of the base film 11, as described below.

Fig. 12 shows a cross-sectional structure of the patch unit for examination 10 along a cross section perpendicular to the surface 11F of the base film 11.

As shown in fig. 12, the inspection patch unit 10 further includes a protective layer 17 covering the surface 11F of the base film 11. The protective layer 17 covers a portion of the surface 11F of the base film 11 that is more inside than the support 13, as viewed from a line of sight opposite to the surface 11F of the base film 11. In the example shown in fig. 12, a state is shown in which the protective layer 17 is in contact with the surface 11F of the base film 11, and has a shape parallel to the surface 11F. Note that the protective layer 17 may have flexibility. In this case, the protective layer 17 has a convex shape from the edge of the protective layer 17 toward the center and along the direction from the base film 11 toward the adhesive layer 12. In addition, the protective layer 17 may have a flat shape which is positioned on the same plane as the support 13 in the thickness direction of the patch main body 10A. In other words, the inspection patch unit 10 may have a gap corresponding to the thickness of the adhesive layer 14 between the surface 11F of the base film 11 and the protective layer 17 in the thickness direction of the patch body 10A. The protective layer 17 may have any of the shapes described above, depending on the rigidity of the protective layer 17.

Fig. 13 shows a planar structure of the patch unit for inspection 10 as viewed from a line of sight opposite to the surface 11F of the base film 11.

As shown in fig. 13, the protective layer 17 covers almost the entire portion further inside than the support 13 as viewed from the line of sight opposite to the surface 11F of the base film 11. The protective layer 17 has a shape similar to the shape that the inner edge of the support 13 has. Thus, the protective layer 17 can cover most of the portion exposed from the support 13 among the surface 11F of the base film 11.

The protective layer 17 and the support 13 are distinguished from each other by a gap G between the protective layer 17 and the support 13. A joint portion 18 that joins the protective layer 17 and the support 13 is located in the gap G. The patch unit for inspection 10 may include 1 or more connection portions 18. In view of suppressing the protective layer 17 from being detached from the support 13 when the patch unit for inspection 10 is transported, etc., the patch unit for inspection 10 preferably includes a plurality of connection portions 18, and the plurality of connection portions 18 are located at intervals in the circumferential direction of the protective layer 17. The length of the coupling portions 18 along the circumferential direction of the protective layer 17 is shorter than the length along the circumferential direction of the protective layer 17 at a portion sandwiched by the two coupling portions 18 among the gap G.

The protective layer 17 may be made of paper or synthetic resin, as in the case of the support 13. The material forming the protective layer 17 may be the same as the material forming the support 13. In this case, one member for forming the support 13 and the protective layer 17 is prepared, and the support 13, the protective layer 17, and the coupling portion 18 can be formed from this member by using punching or laser processing. When the support 13, the protective layer 17, and the connecting portion 18 are formed by punching or laser processing, the fragile portion 13a of the support 13 may be formed by the same processing method.

When the patch unit for inspection 10 is used, the protective layer 17 is separated from the support 13 by breaking the connection portion 18. By exposing a part of the surface 11F of the base film 11, the coordinate grid 16 formed on the base film 11 can be exposed to the outside.

Thus, according to the inspection patch unit 10 provided with the protective layer 17, the following effects can be obtained.

(11) The portion exposed from the support 13 among the surface 11F of the base film 11 is covered with the protective layer 17, and therefore the portion covered with the protective layer 17 can be kept clean before the patch main body 10A is used for inspection.

The patch unit for inspection 10 may not include the connection portion 18 for connecting the protective layer 17 and the support 13. Even in this case, the effect (11) can be obtained by providing the inspection patch unit 10 with the protective layer 17.

The protective layer 17 may have a shape that covers only a part of the portion exposed from the support 13 among the surface 11F when viewed from a line of sight opposite to the surface 11F of the base film 11. Even in this case, the effect based on the above (11) can be obtained at least in the portion covered with the protective layer 17 among the surface 11F.

The protective layer 17 may cover both the support 13 and a portion of the surface 11F of the base film 11 that is more inside than the support 13, as viewed from a line of sight opposite to the surface 11F of the base film 11. In this case, the protective layer 17 preferably has flexibility that can have a shape along the level difference formed by the support 13 and the surface 11F of the base film 11.
