Technical Field

The present invention relates to a biological information measurement device, a biological information measurement system, and a plug-in for performing continuous blood glucose measurement, for example.

Background

A conventional biological information measurement device is configured to include the following elements: an adhesive tape provided on the lower surface side and having an adhesive surface adhered to the skin of the user; a mounting substrate arranged on the upper surface side of the adhesive tape; and a sensor electrically connected to the mounting board and configured to transfer a part of the mounting board to the skin side of a user (for example, patent document 1).

Further, a conventional biological information measurement system includes: an adhesive tape; a mounting substrate arranged on the upper surface side of the adhesive tape; a sensor electrically connected to the mounting substrate; and a cover covering the upper surface side of the mounting substrate. The biological information measurement device is incorporated in a plug, and the biological information measurement device is attached to the human body by operating the plug (for example, patent document 2).

Patent document 2: japanese laid-open patent publication No. 2015-509011

Disclosure of Invention

In patent document 1, a flexible substrate is used as a mounting substrate. Therefore, it is expected that the flexible substrate will be flexed along the shape of the body part to which the biological information measurement device is attached, thereby improving the attachment feeling to the skin. Thereafter, the flexible substrate and the adhesive tape are covered with a cover.

However, in the above-described conventional structure, the assembling feeling in use after the assembling cannot be improved. This is because, if the mounting substrate is a flexible substrate, the flexible substrate is bent along the shape of the mounting portion when the flexible substrate is mounted on the body. Therefore, although the biological information measurement device can be mounted in a state of fitting to the body at the time of mounting, the skin, bone, and muscle of the body are largely displaced in accordance with the living activities, and therefore, in this state, the flexible substrate that is flexed in the mounted state may suppress the displacement of the skin. For example, the skin to be stretched is inhibited from being displaced by the flexible substrate, and thus the user feels a sense of incongruity, and improvement of the assembling property is desired.

Therefore, the 1 st object of the 1 st invention is to improve the assembling property of the biological information measuring apparatus.

On the other hand, in patent document 2, the plug is incorporated with a biological information measuring device and is attached to a human body. Therefore, the size of the plug is increased, and as a result, the use experience is poor.

Therefore, the 2 nd object of the 2 nd invention is to improve the use experience when assembling the biological information measurement device.

To achieve the above object 1, the 1 st aspect of the present invention includes: an adhesive tape having an adhesive surface on a lower surface side thereof to be adhered to the skin of a user; a mounting substrate arranged on the upper surface side of the adhesive tape; a sensor electrically connected to the mounting board and measuring biological information; and a cover covering the upper surface side of the mounting substrate. The lower surface side of the mounting substrate and the upper surface side of the adhesive tape are in a non-adhesive state, and the adhesive tape and the cover have higher stretchability than the mounting substrate.

With this configuration, the above object 1 is achieved.

In order to achieve the above 2 nd object, the 2 nd invention is a biological information measurement system including: a biological information measuring device for measuring biological information of a user; an insert which is placed on the upper surface of a biological information measurement device and to which the biological information measurement device is attached to the skin of a user, the biological information measurement device comprising: an adhesive tape having an adhesive surface provided on a lower surface side and adhered to a user's skin; a mounting substrate arranged on the upper surface side of the adhesive tape; a substrate holding part which is provided on the upper surface side of the adhesive tape and holds the mounting substrate; a sensor electrically connected to the mounting board and used for measuring biological information; and a cover covering the upper surface side of the mounting substrate and having a through hole formed in a portion of the substrate holding portion. The plug-in unit is provided with: a bottom body which is mounted at a position including a through hole in an upper surface of a cover of the biological information measurement device and is supported by an upper end portion of a substrate holding portion of the biological information measurement device; and a top body attached to the bottom body and having flexibility to be elastically deformed by being pressed when the biological information measurement device is attached to the skin.

With this configuration, the above object 2 is achieved.

(effect of the invention)

As described above, the invention of claim 1 provides elasticity to the adhesive tape to be adhered to the skin of the user and the cover on the upper surface side, and the mounting substrate present between the adhesive tape and the cover is held by the substrate holding portion provided on the upper surface side of the adhesive tape. Further, since the lower surface side of the mounting board is not adhered to the upper surface side of the adhesive tape, the mounting property of the biological information measuring device to the skin can be improved.

That is, since the adhesive tape and the cover having high elasticity are used, the biological information measuring device can be attached along the skin when the device is attached to the skin. In addition, when the displacement (movement) of the body occurs after the assembly, the adhesive tape and the cover expand and contract to give less uncomfortable feeling to the body, and therefore, the assembly of the biological information measurement device can be improved more than in the past.

As described above, according to the invention of claim 2, the insert includes: a bottom body attached to an upper surface of the biological information measurement device; and a top body assembled on the bottom body and having flexibility.

That is, since the plug is attached to the upper surface of the biological information measurement device, the plug can be made smaller, and the biological information measurement device can be easily attached with a finger using the plug.

As a result, the use experience of the biological information measurement device at the time of assembly can be improved compared to the past.

Detailed Description

Hereinafter, one embodiment of the present invention will be described in detail together with the accompanying drawings.

(embodiment mode 1)

The biological information measurement system 1A including the biological information measurement device 6 and the plug 7 according to the present embodiment will be described below with reference to the drawings.

In the following description, terms indicating specific directions and positions (for example, "up", "down", "right", "left", and other terms including these terms) are used, but these terms are used for ease of understanding the disclosure with reference to the drawings, and the technical scope of the present invention is not limited by the meaning of these terms.

(1) Configuration of biological information measurement system 1A

The biological information measurement system 1A of the present embodiment is used, for example, to attach a biological information measurement device 6 for measuring biological information such as a blood glucose level to the upper arm of a user or the like using a plug 7.

Fig. 1 shows a state in which a sterile package 1 containing a biological information measuring device 6 and a plug 7 and a sterile package 3 containing a cover tape (over tape)2 are housed in a container 4. That is, the biological information measuring apparatus is managed and transported in a sterilized state in the container 4 as shown in fig. 1 before being attached to the skin 5 of the upper arm of the user who measures the biological information as shown in fig. 25. In the present embodiment, the biological information measurement system 1A is configured by the biological information measurement device 6 and the plug 7.

Fig. 2 and 3 show a biological information measurement device 6 and a plug 7 constituting the biological information measurement system 1A.

As shown in fig. 2 and 3, a plug 7 used for attaching the biological information measurement device 6 to the upper arm of the user or the like is detachably attached to the upper surface of the biological information measurement device 6. As described above, the biological information measurement device 6 and the plug 7 are stored in the sterile package 1 before use as shown in fig. 1.

(2-1) configuration of biological information measuring device 6

The biological information measurement device 6 has the configuration shown in fig. 4 to 8.

That is, the biological information measurement device 6 includes, as shown in fig. 4 and 7, an adhesive tape 8, a base 12, a mounting board 13, a sensor 17, a guide pin insertion tube 18 (an example of a board holding portion), and a cover 19.

Fig. 26 is an electrical block diagram of the biological information measurement device 6.

The measurement value measured by the measurement unit 30 using the sensor 17 is stored in the storage unit 32 via the control unit 31. The measurement value stored in the storage unit 32 is transmitted to the mobile device 34 via the communication unit 33.

As shown in fig. 7, a substantially circular adhesive tape 8 is provided on the skin 5 side of the body in the biological information measurement device 6. The adhesive tape 8 is made of a stretchable material such as rubber, elastomer, nonwoven fabric, or adhesive. A through hole 8A is provided in the center of the adhesive tape 8.

As shown in fig. 7, the adhesive tape 8 is provided with a base 12 in which an outer circumferential portion 9 and an inner circumferential portion 10 are connected to each other at an interval of 120 degrees by a bridge portion 11.

The outer circular portion 9 forms the outermost peripheral portion of a substantially annular base 12 and is disposed concentrically with the inner circular portion 10. The outer circular portion 9 and the inner circular portion 10 are connected to each other via 3 bridge portions 11 arranged in the radial direction.

The lower surface of the adhesive tape 8 is an adhesive surface over the entire surface. On the other hand, the adhesive tape 8 has an adhesive surface on the upper surface thereof only at the portions of the outer circumferential portion 9, the inner circumferential portion 10, and the bridge portion 11. The base 12 is thereby held in a state of being bonded to the adhesive tape 8.

Next, as shown in fig. 4, 7, and the like, a mounting substrate 13 is bonded to the inner peripheral portion 10 of the base 12. As shown in fig. 8, the mounting substrate 13 is divided into 3 portions at substantially equal angular (120-degree) intervals. Electronic component 14 and battery 15 are disposed on the upper surface of each of mounting boards 13 divided into 3 parts. As shown in fig. 7, the mounting substrate 13 divided into 3 parts is disposed on the base 12 between the bridge parts 11 disposed at intervals of 120 degrees.

More specifically, the mounting substrate 13 divided into 3 parts has a substantially fan-like shape having an angular range slightly smaller than 120 degrees. Therefore, between the bridge portions 11, 3 mounting substrates 13 are disposed in a non-contact state with the bridge portions 11 so as not to overlap with the bridge portions 11 in a top view.

Thus, the spacer 16 disposed on the back side of the mounting substrate 13 can be disposed so as to ride on the bridge portion 11 without interfering with the bridge portion 11.

The mounting substrate 13 is molded using a resin such as polyimide or polyester used for a flexible substrate. These materials are soft in the bending direction, but are not stretchable in a direction substantially parallel to the substrate surface in a state of being attached to the skin 5.

Further, fan-shaped spacers 16 are bonded to the lower surfaces of the divided 3 mounting substrates 13, i.e., the surfaces on the adhesive tape 8 side, as shown in fig. 8. That is, the mounting board 13 is placed on the adhesive tape 8 in a non-adhesive state with the spacer 16 interposed therebetween. That is, by adhering to the mounting board 13, it is possible to suppress the inhibition of the expansion and contraction of the adhesive tape 8 due to the influence of the mounting board 13 having no elasticity in the direction along the surface of the skin 5.

The base 12 is made of a stretchable material such as rubber or an elastomer. The base 12 is formed by connecting the outer circular portion 9 and the inner circular portion 10 to each other at an interval of 120 degrees via a bridge portion 11 as shown in fig. 7. Therefore, even when the chassis 12 is bonded to the upper surface of the adhesive tape 8, the expansion and contraction of the adhesive tape 8 is not hindered by the stretchable chassis 12.

The sensor 17 is electrically connected to the mounting board 13 as shown in fig. 4. The sensor 17 is bent upward at its central portion, and the distal end of the leg portion is held in a state inserted into the through hole 8A of the adhesive tape 8.

A guide pin insertion tube 18 (an example of a substrate holding portion) is bonded and fixed to the upper surface side of the mounting substrate 13 corresponding to the inner peripheral portion 10 of the base 12. That is, the mounting substrate 13 is held on the outer periphery of the guide pin insertion tube 18. In addition, the guide needle insertion cylinder 18 has a cylindrical shape. The center axis of the guide pin insertion cylinder 18 is arranged to coincide with the center axis of the through hole 8A of the adhesive tape 8. As shown in fig. 4, the central portion of the sensor 17 is disposed inside the guide needle insertion tube 18.

The guide needle insertion tube 18 is formed of, for example, resin. That is, the guide pin insertion tube 18 is preferably formed of a material harder than the adhesive tape 8, the base 12, the mounting board 13, and the cover 19.

Thus, since the guide needle holding portion 18 for holding the guide needle 26 is formed of a hard material which is hard to deform, the guide needle 26 does not shake during the puncturing operation, and the puncturing operation of the guide needle 26 to the skin 5, which will be described later, can be stably and accurately performed.

As shown in fig. 5, the upper surface of the adhesive tape 8 and the lower surface of the chassis 12 are bonded to each other at a bonding portion a on the outer peripheral edge. As shown in fig. 5, the upper surface of the base 12 and the lower surface of the cover 19 are bonded to each other at a joint B of the outer peripheral edge. That is, the adhesive tape 8 and the cover 19 are adhered to each other at the outer peripheral edge portions via the base 12.

As shown in fig. 5, the substantially cylindrical upper surface of the guide needle insertion tube 18 provided near the center of the substantially disc-shaped biological information measurement device 6 and the lower surface of the cover 19 are bonded to each other at a position on the inner peripheral side (a bonding portion C).

The lower surface of the guide needle insertion cylinder 18 and the upper surface of the mounting board 13 are bonded to each other at positions on the inner peripheral side in the same manner as the bonding portions C (bonding portions D are bonded to each other).

The lower surface of the mounting substrate 13 and the upper surface of the base 12 are bonded to each other at a position (bonding portion E) below the bonding portion D of the guide pin insertion cylinder 18.

The upper surface of the adhesive tape 8 and the lower surface of the base 12 are bonded to each other at a position (bonding portion F) below the bonding portion D of the guide pin insertion cylinder 18.

That is, the band 8, the cover 19, and the holder 12 are bonded to each other at the outer peripheral edge portion and the vicinity of the center of the substantially disk-shaped biological information measuring device 6.

The mounting board 13 is bonded to the adhesive tape 8, the cover 19, and the base 12 via the guide needle insertion tube 18 in the vicinity of the center of the substantially disc-shaped biological information measurement device 6.

Further, a cover 19 is disposed on the mounting substrate 13 as shown in fig. 7. The cover 19 is made of elastic material such as rubber or elastomer. As shown in fig. 7, a through hole 20 having substantially the same inner diameter as the through hole 8A is provided in the center of the cover 19.

The outer peripheral edge of the lower surface side of the through hole 20 is bonded and fixed to the upper end surface of the substantially cylindrical guide needle insertion tube 18. The outer peripheral lower surface of the cover 19 is bonded and fixed to the upper surface of the outer peripheral portion 9 of the base 12. The cover 19 is disposed in a non-adhered state to the mounting substrate 13. That is, the cover 19 is disposed in a state of being freely expanded and contracted without being affected by the mounting substrate 13.

In the present embodiment, the mounting substrate 13 is disposed on the adhesive tape 8 with the spacer 16 bonded to the lower surface side interposed therebetween. For this reason, the mounting substrate 13 is placed in a non-adhesive state with respect to the adhesive tape 8. An adhesive surface is provided only at the portions of the outer circumferential portion 9, the inner circumferential portion 10, and the bridge portion 11 on the upper surface of the adhesive tape 8. Therefore, the mounting board 13 and the spacer 16 are not bonded to the adhesive tape 8. The mounting board 13 is also mounted on the lower surface of the cover 19 in a non-adhesive state.

This allows the adhesive tape 8 and the cover 19 to smoothly expand and contract without being affected by the mounting board 13. In addition, when the adhesive tape 8 and the cover 19 are stretched, the mounting substrate 13 is not affected by the displacement of the adhesive tape 8 and the cover 19. Therefore, the reliability of the mounting substrate 13 is also ensured.

Further, in the present embodiment, as shown in fig. 6, the mounting substrate 13, and the electronic component 14, the battery 15, and the spacer 16 mounted thereon are covered with a waterproof film 21. Therefore, deterioration of the mounting substrate 13 due to moisture can be suppressed.

Further, the waterproof film 21 covering the lower surface side of the spacer 16 may be peeled off by friction when the adhesive tape 8 expands and contracts. However, the portion peeled off by the friction is only the lower surface side of the spacer 16, and the peeling of the thickness direction and the upper surface portion thereof does not occur. Therefore, a decrease in the function as the waterproof film 21 can be avoided. The spacer 16 is formed using a soft material such as elastomer, rubber, or silicon.

(2-2) Structure of insert 7

The plug-in 7 included in the biological information measurement system 1A of the present embodiment is a device used for attaching the biological information measurement device 6 to the upper arm of the user or the like, and is attached to the upper surface of the biological information measurement device 6 as shown in fig. 2, 3, and 7.

The plug 7 includes a substantially circular bottom body 22 and a circular container-shaped top body 23 in a state of being mounted on the biological information measurement device 6.

The bottom body 22 covers the upper surface side of the cover 19 of the biological information measurement device 6, and is supported at the upper end portion of the guide needle insertion tube 18 via the cover 19. The bottom body 22 has a guide cylinder 24 protruding from the vicinity of the substantially central portion of the substantially circular upper surface toward the top body 23 side.

The top body 23 is mounted on the bottom body 22, and has flexibility. As shown in fig. 3, the top main body 23 has a substantially cylindrical guide needle holder 25 vertically movable on the inner peripheral surface side of the guide cylinder 24.

The substantially cylindrical guide needle holding portion 25 holds the guide needle 26 along the central axis of the substantially cylindrical column. Then, the guide pin 26 moves the sensor 17 toward the skin 5 of the user by pressing the central portion of the upper surface of the top body 23 toward the bottom body 22. That is, the guide cylinder 24 provided in the bottom main body 22 is provided to prevent a positional deviation when the sensor 17 is transferred and to position the guide pin holding portion 25 when it is transferred.

In the above configuration, the user first takes out the biological information measuring device 6 to which the plug 7 is attached from the case 4 shown in fig. 1, and then, as shown in fig. 9, attaches the biological information measuring device 6 to the skin 5 of the upper arm portion while keeping the state of the plug 7 attached, by the adhesiveness of the adhesive tape 8.

Next, as shown in fig. 10, 12, and 13, when the user presses the upper end surface of the inserter 7, the guide needle holding portion 25 of the inserter 7 is slidably guided by the guide cylinder 24 and pressed downward, that is, toward the skin 5 side, as shown in fig. 13. Thus, the sensor 17 is retracted toward the skin 5 by the guide needle 26, and the distal end portion of the sensor 17 can be transferred into the skin 5.

Thereafter, as shown in fig. 19 and 20, the guide pin holding portion 25 of the card 7 is automatically returned to the upper steady position by the elastic force (restoring force) of the card 7. Thereby, the tip of the guide needle 26 inserted into the skin 5 is pulled out from the skin 5.

As shown in fig. 16 and 17, top main body 23 has a wall thickness of bent portion 23G thinner than that of lower portion 23H, and bent portion 23G has a wall thickness thicker than that of bent portion 23I and 23J.

Thus, when the upper end surface of the tip main body 23 is pressed, the portion of the bent portion 23G having a small thickness is elastically deformed and pressed, and the portion of the pressing portion 23H disposed on the outer peripheral side of the guide pin holding portion 25 is hardly deformed because of its large thickness.

Similarly, when the portion of the thin folded portion 23G is elastically deformed, the folded portions 23I and 23J having a thickness larger than that of the folded portion 23G are hardly elastically deformed, and the portion of the pressing portion 23H is pressed with the folded portions 23I and 23J as fulcrums.

As a result, a stronger elastic force for returning the top main body 23 to the steady state can be used, and the guide needle holder 25 can be operated more accurately and stably in the vertical direction.

In addition, by the above-described operation, the sensor 17 is inserted into the wound formed by the insertion of the guide needle 26 into the skin 5, and when the guide needle 26 is pulled out from the skin 5, the sensor 17 is left in the skin 5 as it is.

The inserter 7 of the present embodiment has the configuration shown in fig. 14 and 15 in order to stably push the introducer needle holding portion 25 holding the introducer needle 26 at the tip toward the skin 5.

That is, the guide tube 24 of the base body 22 has, on its upper end side, a divided piece 27 divided by 4 in the circumferential direction. The divided piece 27 has a projection 28 projecting in the outer circumferential direction (radially outward).

Therefore, when the top body 23 is pushed down, the projections 28 of the divided pieces 27 are pushed inward in the radial direction. Then, when the pressing force exceeds the projection 28, the pressing force of the pushing operation is rapidly transmitted to the guide needle holding portion 25, and therefore a constant pressing force can be ensured. For this reason, the guide needle 26 is reliably pushed toward the skin 5 side.

In the present embodiment, when the sensor 17 is transferred into the skin 5 by the pressing operation of the guide needle 26, the configuration shown in fig. 16 to 18 is employed so that the sensor 17 is not disconnected by the abrupt pushing operation of the guide needle 26.

That is, as shown in fig. 18, an elastic portion 17A that meanders is provided in the vicinity of a portion of the sensor 17 with which the tip of the guide pin holding portion 25 contacts. Thus, even when the tip of the sensor 17 is pushed into the skin 5 rapidly, the sensor 17 can be prevented from being broken partially.

Thereafter, as shown in fig. 20, the tip of the sensor 17 is moved into the skin 5, and after the top portion of the main body 23 is returned to the steady-state position by the elastic force, the card 7 is detached from the upper surface (cover 19) of the biological information measurement device 6 as shown in fig. 21 and 22. That is, a part of the bottom main body 22 of the card 7 is bonded to the cover 19 in a point contact state. Therefore, as shown in fig. 21, the plug 7 can be easily detached from the biological information measurement device 7.

At this time, the adhesive strength of the point contact portion between the bottom main body 22 of the package 7 and the cover 19, the adhesive strength between the cover 19 and the guide pin insertion tube 18, the adhesive strength between the guide pin insertion tube 18 and the mounting board 13, the adhesive strength between the mounting board 13 and the base 12, the adhesive strength between the base 12 and the adhesive tape 8, and the adhesive strength between the adhesive tape 8 and the skin 5 shown in fig. 5 are sufficiently small.

This makes it possible to easily detach the plug 7 from the biological information measurement device 7, as shown in fig. 21.

When the plug 7 is detached from the biological information device 6, the cover tape 2 is attached to the upper surface side of the cover 19 as shown in fig. 23 and 24.

The cover tape 2 is made of elastic material such as rubber or elastomer. As shown in fig. 24, a projection 29 for inserting the guide needle into the guide needle insertion tube 18 is provided at a portion of the cover tape 2 corresponding to the guide needle insertion tube 18.

That is, the projection 29 abuts from above on the middle portion of the sensor 17 that guides the contact of the tip of the needle holding portion 25 when the biological information measurement device 6 is attached to the skin 5. This prevents the sensor 17 from being inadvertently pulled upward.

Through the above-described operation, the biological information measuring device 6 is attached to the skin 5 of the upper arm of the user as shown in fig. 25.

In the biological information measurement system 1A of the present embodiment, the biological information measurement device 6 can be easily attached to the skin 5 of the upper arm of the user by hand using the adhesiveness of the adhesive tape 8.

In addition, when the top main body 23 is pushed toward the skin 5 by the hand of the user who is fitting the plug 7 in a state where the biological information measurement device 6 is adhered to the skin 5, the sensor 17 can be easily transferred into the skin 5 by the guide pin 26.

Further, the plug 7 bonded to the cover 19 of the biological information measurement device 6 by point contact can be easily removed by hand thereafter, and the cover tape 2 can be manually attached to the upper surface of the biological information measurement device 6 as shown in fig. 24, whereby the assembly of the biological information measurement device 6 to the skin 5 can be completed.

As shown in fig. 24, the assembled biological information measurement device 6 has a thin shape that gradually increases in thickness toward the center portion of a substantially disk shape. This prevents the biological information measurement device 6 from being projected from the surface of the skin 5 after assembly, and thus can be assembled without visual discomfort.

< main feature >

The adhesive tape 8, the cover 19, and the base 12 of the biological information measurement device 6 according to the present embodiment are formed of a member that is stretchable in the direction along the surface of the skin 5 and the direction intersecting the surface of the skin 5 in the assembled state, and are joined to the outer peripheral edge portion. The adhesive tape 8, the cover 19, and the center portion of the base 12 are fixed to the mounting board 13 which is not stretched in the direction along the surface of the skin 5 via the guide needle insertion tube 18.

That is, when the biological information measurement device 6 is attached to the skin 5, the adhesive tape 8, the cover 19, and the cover tape 2 of the biological information measurement device 6 are flexible and stretchable.

Thus, the biological information measurement device 6 can be mounted along the skin 5 to be mounted, and therefore the biological information measurement device 6 with high mounting performance can be obtained.

Further, since the outer peripheral edge portion of the adhesive tape 8, the cover 19, and the cover tape 2 can be attached to the skin 5 while being stretched, the elastic property in the direction along the surface of the skin 5 and the flexibility in the direction intersecting the surface of the skin 5 are provided, and therefore the fitting feeling during assembly can be further improved.

Further, in the present embodiment, since the adhesive tape 8, the cover 19, and the cover tape 2 are stretched and contracted in accordance with the movement of the human body in actual use, the sense of incongruity is less likely to be felt when the human body is moved, and the assemblability can be further improved.

In order to obtain such an effect, it is also preferable that, as shown in fig. 4, the battery 15 and the electronic component 14 are mounted on the mounting board 13 at positions closer to the guide pin insertion cylinder 18 than to the height.

As described above, the adhesive tape 8 and the cover 19 of the present embodiment can be formed of a material, such as an elastic body, which is stretchable in the direction along the surface of the skin 5 and the direction intersecting the skin 5, in the base 12.

On the other hand, the mounting substrate 13 is molded using a resin such as polyimide or polyester used for a flexible substrate as described above. These materials are soft in the bending direction, but are not stretchable in a direction substantially parallel to the substrate surface.

The adhesive tape 8, the cover 19, the base 12, and the mounting substrate 13 have flexibility in the bending direction. The mounting substrate 13 is placed on the adhesive tape 8 in a non-adhesive state with the spacer 16 interposed therebetween.

This allows the skin 5 to be attached to the skin in a manner that fits the curvature of the skin 5 to be attached, without being affected by the mounting board 13.

In the present embodiment, as shown in fig. 5, the mounting board 13 has a thin portion 13A (see fig. 18) provided along the periphery of the guide needle insertion cylinder 18 in the vicinity of the guide needle insertion cylinder 18. This enables the mounting substrate 13 to be more flexibly bent in the bending direction intersecting the substrate surface.

In addition, the adhesive tape 8, the cover 19, and the chassis 12 have stretchability in a direction parallel to the surface of the skin 5 in the assembled state. This makes it possible to attach the adhesive part while extending to both sides like a bandage.

At this time, the mounting board 13, which is not stretchable in the direction parallel to the surface of the skin 5 in the mounted state, is fixed only at the central portion with respect to the adhesive tape 8, the cover 19, and the chassis 12, which are stretchable in the direction parallel to the surface of the skin 5 in the mounted state.

Thus, even when the attachment substrate 13 is stretched in both sides and stuck to the skin 5, the attachment substrate is not stretched in the horizontal direction.

Further, since the biological information measuring device 6 can be folded in the vertical direction in accordance with the curved shape of the surface of the skin 5 to be attached, the biological information measuring device can be attached in a state of fitting to the surface of the skin 5 like a sticking bandage.

The present invention is expected to be effectively applied to, for example, a biological information measurement device that performs continuous blood glucose measurement.
