[ detailed description ] embodiments

Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. The terms and words used in the present specification and claims should not be interpreted as being limited to the meanings commonly used or dictionary, and should be interpreted according to the meanings and concepts conforming to the technical idea of the present invention on the basis of the principle that the inventor can appropriately define the concept of the terms to explain his invention in the best way.

Therefore, the structure illustrated in the drawings of the embodiments described in the present specification is only one of the most preferred embodiments of the present invention, and does not represent all embodiments of the technical idea of the present invention, so that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features thereof when the present invention is applied; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.

[ example 1]

As shown in fig. 1 to 7, the test strip cutting device for diagnostic test strips according to embodiment 1 of the present invention is configured to cut a diagnostic test strip 10, which is manufactured in a long plate shape and provided, into a plurality of test strips 11 formed in a strip shape at a time in a width direction, and includes a frame 100, a first shaft 200', a second shaft 200 ″ and a guide member 300.

In particular, the guide member 300 is inserted through the first shaft 200 'and the second shaft 200 ″ and can cut the test strip 11 while rotating the first shaft 200' and the second shaft 200 ″ facing each other in a state of supporting both side surfaces of the diagnostic test strip 10, and can cut the test strip 11 in a state of supporting both surfaces of the diagnostic test strip 10, thereby not only cutting the test strip 11 in a predetermined form, but also preventing the test strip 11 from being twisted or being caught between the blades 210 'or from being cut or bent due to the rotation of the first shaft 200' or the second shaft 200 ″.

Further, at least two concentric adjusting screws 231 are screwed to the adjusting nut 230, which is alternately clamped into the adjusting nut 230 having the blades 211 fitted to the first shaft 200 ' and fixed by the two blades 210 ' and the spacers 210 ″ facing each other, on the first shaft 200 ', so that the blades 210 ' and the spacers 210 ″ can be pressed by the concentric adjusting screws 231 and aligned concentrically when the adjusting nut 230 cannot equally press the blades 210 ' and the spacers 210 ″.

In addition, since the adjustment screws 271 are provided at both ends of the first shaft 200 'to be movable in the longitudinal direction of the first shaft 200', the blade 210 'between the first shaft 200' and the second shaft 200 ″ can be precisely engaged by the adjustment.

These structures are described in further detail below with reference to the accompanying drawings. Here, the reference numeral "10" denotes a strip-shaped diagnostic strip provided with a reagent for diagnosis and the like on one side, and "11" denotes each strip obtained by cutting the diagnostic strip into a plurality of strips at a time.

I. Frame structure

As shown in fig. 1 and 2, the frame 100 supports a first shaft 200 'and a second shaft 200 ″ and a guide member 300, which will be described later, and the diagnostic strip 10 is inserted between the first shaft 200' and the second shaft 200 ″ and cut into a plurality of strips 11. As described above, the frame 100 may be formed in any shape as long as it can support both ends of the first shaft 200' and the second shaft 200 ″, and an example of forming the frame in a lattice shape is shown in the drawing.

II. First and second shafts

The first shaft 200' and the second shaft 200 ″ are constructed such that both ends are assembled on the frame 100 to be rotatable in situ and a structure is formed on the outer circumference such that one diagnostic strip 10 can be cut into a plurality of strips 11 at a time, as shown in fig. 1 to 3.

Here, since the first shaft 200 'and the second shaft 200 ″ have the same structure, the first shaft 200' will be described as a reference, and the second shaft will not be described in detail. Further, the first shaft 200 'and the second shaft 200 "are, as shown in fig. 3, respectively composed to rotate in situ, but it is preferable that gears 220, which can be engaged with each other, are respectively mounted on the first shaft 200' and the second shaft 200" to rotate together at the same time.

To this end, the first shaft 200' is, as shown in fig. 2 and 3, provided on both ends with bearings 250 ", 260, which are supported to be rotatably assembled in situ. The blade 211 is alternately sandwiched between two blades 210' and spacers 210 ″ facing each other on the outer periphery, and then the adjustment nut 230 is screwed and fixed. In this state, the first shaft 200 'is provided with a key slot 280 to clamp the blades 210' and spacers 210 "in place so that they cannot rotate in place.

1. Blade

The blade 210' is formed in a disc shape as shown in fig. 3 to 5. In this state, the blades 210 ' are provided with cutting edges 211 at the edges of one side surface as shown in fig. 4, so that the blades 210 ' respectively mounted on the first shaft 200 ' and the second shaft 200 ″ can cut the diagnostic strip 10 using a shearing force like scissors.

In the preferred embodiment of the present invention, it is preferable that the cutting edge 211 'is provided at the edge portion of the blade 210' to facilitate the cutting of the diagnostic strip 10 into the test strip 11. Here, the first angle θ 1 forming the cutting edge 211' is formed larger than the second angle θ 2 forming the cutting edge 211, and the test strip 11 can be cut neatly while being cut slowly. Here, the first angle θ 1 is most preferably made at an angle of 43 to 47 ° (most preferably 45 °), and the second angle θ 2 is made at an angle of 8 to 12 ° (most preferably 10 °).

As shown in fig. 5, the insert 210 'has a mounting hole 212 formed through the center thereof so as to be inserted into the first shaft 200', and another key groove 213 formed on one side of the mounting hole 212 so as to be inserted into the key groove 280.

In the thus formed blade 210 ', as shown in fig. 4, the two blades 210' are closely attached to each other with the cutting edges 211 facing each other, the later-described spacer 210 "is closely attached to one side thereof, and the two blades 210 'and one spacer 210" are continuously and non-rotatably fitted to the first shaft 200'. Therefore, when the diagnostic strip 10 is cut by the blade 210' of the present invention, the strip is cut between the two blades 211 facing each other and between the surfaces facing each other without the blades 211 being formed, and both sides of the strip 11 are cut by an equal force, thereby preventing the strip 11 from being deformed or bent.

2. Spacing piece

The spacer 210 "is fitted snugly onto said first shaft 200 'on the side of the two blades 210' where the cutting edges 211 are fitted facing each other, as shown in fig. 3 and 4. Further, with the blade edge 211 being one unit of two blades 210 'and spacers 210 ″ disposed facing each other, a plurality of units are fixed by being sandwiched by the first shaft 200'.

In this state, the spacer 210 ″ is manufactured in a disc shape and has a smaller diameter than the blade 210 ', thereby securing a space for the blade 210' to cut the diagnostic strip 10. Also, the spacer 210 "is non-rotatably mounted to the first shaft 200 ' as in the insert 210 ', and thus provides a mounting hole 212 and a key slot 213, but these structures are the same as those described above for the insert 210 ' and thus will not be described in detail.

In the preferred embodiment of the present invention, when the spacer 210 ″ is assembled with the guide member 300 described later as shown in fig. 4, it is most preferable that the guide member 300 is provided on the spacer 210 ″ and the guide member 300 is provided so as to penetrate between the spacers 210 ″ provided on the first shaft 200' and the second shaft 300 ", respectively, and the diagnostic test strip 10 is cut into test strips 11 when passing between the guide members 300.

3. Adjusting nut

As shown in fig. 3 and 6, the adjusting nut 230 is screwed on the first shaft 200 'in a state that the blade 210' and the spacer 210 "are inserted into one side of the first shaft 200 ', and the blade 210' and the spacer 210" are supported and fixed to each other.

Further, at least two concentric adjusting screws 231 are disposed on the adjusting nut 230 to press the above-mentioned insert 210' and spacer 210 ″. Because the adjustment nut 230 is screwed on the first shaft 200 ', the clearance angle θ is easily generated from the screw characteristics as shown in fig. 6(b), and the possibility that the insert 210' and the spacer 210 "are out of concentricity is high regardless of how firmly the concentric adjustment screw 231 is screwed. As described above, if the concentricity is not uniform, there is a possibility that the blade 210' and the spacer 210 ″ may be shaken to cause problems such as failure to cut the diagnostic strip 10 uniformly or the presence of a gap between the cut strips 11. Therefore, in the present invention, even though the adjustment nut 230 cannot be closely attached to the blade 210' and the spacer 210 ", the concentric adjustment screw 231 keeps the concentric state while closely attaching the same, and the test strip 11 is cut from the diagnostic test strip 10 according to a predetermined standard, thereby preventing the occurrence of a problem such as the cut test strip 11 being sandwiched therebetween.

In a preferred embodiment of the present invention, at least two concentric adjusting screws 231 are provided, preferably, the interval between the adjacent two is constantly set, and most preferably, eight concentric adjusting screws 231 are provided at the same interval. Since it is not known which side the slit angle θ will appear when the adjustment nut 230 is rotationally adjusted, setting the interval between the concentric adjustment screws 231 narrower allows the concentricity to be adjusted by, for example, the concentric adjustment screw 231 that is finally close.

As described above, it is apparent to those skilled in the art of the present invention that the concentricity of the blade 210' is checked and adjusted using the concentricity gauge or the like after the concentricity is adjusted by the concentricity adjustment screw 231. Such a concentric adjusting screw 231 may be disposed only on one side of the first shaft 200', but preferably, one is disposed on each of both sides, so that when the concentricity is adjusted, the concentricity can be easily and accurately adjusted because the adjustment is performed on both sides.

The unexplained reference numeral "290" is a spacer for adjusting the distance used by being clamped on the first and second shafts 200 'and 200 ", and may be inserted and used as needed when the number of the assembling or the position of the blades 210' and the spacer 210" is required to be adjusted according to the length of the diagnostic strip 10.

III, guide member

The guide member 300, as shown in fig. 1, 2, 4 and 7, is composed of a first guide 310' and a second guide 310 ″ and is assembled to the frame 100 described above.

As shown in fig. 1, 4 and 7, the first guide 310 ' is positioned on the spacer 210 "attached to the first shaft 200 ', the second guide 310" is positioned on the spacer 210 "attached to the second shaft 200", and the first shaft 200 ' and the second shaft 200 "are provided so as to penetrate therethrough. In addition, the first guide 310' and the second guide 310 ″ should be spaced apart to support the diagnostic strip 10 on both sides.

Thus, the guide member 300, as shown in fig. 1, can support the diagnostic strip 10 until it passes completely between the first shaft 200' and the second shaft 200 "and is cut into strips 11. Therefore, as shown in fig. 4, the guide member 300 can stably support the diagnostic strip 10 inserted into the rectangular space, and the support blade 210 ' can stably cut the strip 11, and can prevent the cut strip 11 from being wound or rolled around the first shaft 200 ' and the second shaft 200 "and being discharged from the first shaft 200 ' and the second shaft 200". Therefore, the test strip 11 cut simultaneously from the guide member 300 can be neatly cut to a desired standard, and the cut test strip 11 can be prevented from being deformed by bending or twisting, thereby reducing a defective rate.

As described above, according to the present invention, the guide member, which is inserted through the first shaft and the second shaft, supports both side surfaces of the diagnostic test strip and cuts the diagnostic test strip into test strips, thereby not only cutting the diagnostic test strip into test strips according to a predetermined standard, but also preventing the cut test strips from being wound around the first shaft or the second shaft, thereby preventing the edges or the end portions of the cut test strips from being caught or bent.

[ example 2]

The test strip cutter for diagnostic test strips according to [ embodiment 2] of the present invention has the same structure as that of [ embodiment 1] described above, as shown in fig. 8, but is different in that a structure capable of flowing in the longitudinal direction is added to the first shaft 200'. Therefore, the supplementary structure will be mainly explained here, and the remaining structure similar to that of the above-described [ embodiment 1] will not be described in detail.

Embodiment 2 is that, as shown in fig. 8, the first shaft 200 ' is adjusted to be movable along the length direction thereof, and then the interval between the blades 210 ' respectively fitted on the first shaft 200 ' and the second shaft 200 ″ is adjusted, so that the diagnostic strip 10 is better cut.

For this reason, as shown in fig. 8, at least one tapered bearing 250 ' is additionally provided on one side of the first shaft 200 ' so that the first shaft 200 ' can be stably supported even though it moves in the longitudinal direction. At this time, the tapered bearing 250' and the bearing 250 ″ are preferably assembled in the frame 100 without being backed up and supported firmly. Further, a compression spring 240 is interposed between the first shaft 200 ' and the tapered bearing 250 ', and thus, the first shaft 200 ' is pressurized in a longitudinal direction, and a repulsive force is provided in an opposite direction to thereby perform a buffering function. The thrust bearing 270 is mounted on the end of the first shaft 200 'to support the first shaft 200', and the thrust bearing 270 is connected to a length adjustment screw 271 rotatably mounted on the frame 100 in situ.

As shown in fig. 8, a thrust bearing 270 is mounted on the other side of the first shaft 200 'to support the first shaft 200', and the thrust bearing 270 is formed by engaging with the length adjustment screw 271 mounted on the frame 100. In this state, when the length adjustment screw 271 needs to be adjusted in length, that is, when the interval between the blades 210 ' respectively mounted on the first shaft 200 ' and the second shaft 200 ″ needs to be adjusted, the length adjustment screw 271 is rotated to move the first shaft 200 ' in the length direction and push the thrust bearing 270 to adjust the length. In this state, the first shaft 200 'is elastically supported by the compression spring 240, and is constantly subjected to a buffering action while the length is adjusted, so that the interval between the adjustment blades 210' is adjusted, and even if the blades are misaligned with each other, the adjustment blades can be returned to the original predetermined position by the buffering action.

As described above, according to the present invention, the first shaft is elastically supported and adjustable in the longitudinal direction, so that it is easy to adjust the position of the blade when it is necessary to adjust the position of the blade, and the diagnostic strip is stably cut, and is elastically supported to provide a buffering action, so that the blade can be protected and the cutting can be accurately performed in a predetermined shape at a predetermined position. Further, since the length of the shaft supported by the thrust bearing can be easily adjusted in the longitudinal direction, the interval or the offset state between the blades provided on the first shaft and the second shaft can be easily adjusted.
