Test strip cutting device for diagnostic test strips

Abstract

The present invention forms a groove in a guide strip supporting a diagnostic test strip. The groove prevents the test strip from being supported by a guide member in the section where the blade cuts the test strip using shear force. This prevents the test strip from being pressed by the guide member due to the force of the blade cutting, thereby eliminating the problem of a pressure line on the test strip caused by the guide member pressing against it. Preferably, the present invention provides a guide member that is interpenetrating between a first axis and a second axis where two blades are disposed facing each other and a spacer are repeatedly arranged, thereby guiding the diagnostic test strip. This allows the section through which the test strip passes to have a slightly rectangular shape. This not only allows the test strip to be accurately cut, but also prevents the cut test strip from being bent or twisted.

Description

Technical Field

[0001] The present invention relates to a test strip cutting device for cutting a strip of diagnostic test paper into test strips of predetermined size. Specifically, when cutting the diagnostic test paper, a groove is formed in the section where the cutting is actually performed in the guide member supporting the two sides. Then, the section of the diagnostic test paper is cut with a blade using shear force to prevent the diagnostic test paper from being pressed by the guide member, and to prevent the generation of pressure lines in the length direction on both sides of the cut test strip, thereby preventing the test strip from having poor quality. The guide member is provided between two axes formed by the continuous arrangement of two blades and spacers disposed opposite to each other to support the two sides of the diagnostic test paper. The test strip is then cut while the guide member stably supports the two sides of the diagnostic test paper. Therefore, not only is the test strip cut neatly, but the cut test strip is also prevented from being rolled up, bent, or twisted, thereby eliminating product defects. Moreover, the angle of the cutting edge that actually plays a cutting role in the blade is formed larger than the angle of the blade, which can stably support the edges of both sides of the cut test strip, thereby preventing the cut test strip from being deformed, twisted or bent. Background Art

[0002] Generally speaking, a diagnostic test strip (test kit) is manufactured by first manufacturing a strip-shaped diagnostic test strip and then cutting the strip with various cutting devices as shown in Patent Documents 1 to 3 below.

[0007] (Patent Document 3) Korean Registered Patent No. 10-2031214

[0008] The invention relates to a test strip cutting and testing device for manufacturing an in vitro diagnostic kit, and provides a test strip manufacturing and testing device for in vitro diagnostics. The device is provided with a supply portion for detecting whether the position of an uncut sheet is fixed by using a first photographing device, a circular rotary cutter for cutting the uncut sheet into a plurality of test strips at the rear end of the supply portion, a test strip supply and demand portion for separating the test strips and moving the test strips at the rear end of the circular rotary cutter, and a test strip quality identification portion for identifying whether the film surface of the test strip is defective or not, thereby eliminating the need for operator intervention, and can simultaneously produce a plurality of test strips while cutting the uncut sheet, and quickly identify whether the plurality of test strips are defective, thereby automatically producing the test strips and identifying whether the test strips are defective or not. According to the device, through the simple process of allowing the uncut sheets to enter the supply section, the production of multiple test strips and the inspection of whether the test strips are defective or not are automatically carried out. The second photographing device identifies the defectiveness inspection to improve the defective inspection rate, and the product performance is also improved. The uncut sheets are made into multiple test strips, and the test strips with defective membrane surfaces among the produced test strips are easily and automatically identified by the test strip quality identification section without the need to discharge the uncut sheets, thereby reducing production costs and improving production efficiency.

[0009] However, the conventional cutting method of inserting the diagnostic test paper between the two wheels and then cutting the test paper into a plurality of test strips has the following problems.

[0010] (1) If you use multiple scissors to cut multiple test strips at once, using two blades to cut the diagnostic test strips may cause the cut test strips to tilt or bend to one side.

[0011] (2) Furthermore, the test strip cut from the diagnostic test paper is easily caught between the blades, and as the shaft rotates, it may be bent, twisted, or caught, which may cause poor cutting.

[0012] (3) A test strip that is bent or tilted to one side in this manner will not cause any abnormality if used for diagnosis. However, if the test strip is placed in a predetermined position in a diagnostic kit, etc., it will be difficult to place the test strip in the diagnostic kit due to the bend.

[0013] (4) Therefore, when using the existing cutting method to make test strips, the test strips that are bent or twisted cannot be used, which not only causes a large number of defective rates, but also causes a factor that reduces the manufacturing efficiency of the diagnostic kit. Summary of the Invention

[0014] Technical issues

[0015] In view of these problems, the present invention provides a test strip cutting device for diagnostic test paper, which forms a groove on the guide strip supporting the diagnostic test paper. The groove prevents the diagnostic test paper from being supported by the guide component in the section where the blade cuts the diagnostic test paper using shear force, thereby avoiding the formation of a pressure line on the test strip caused by the guide component pressing the test strip with the force of the blade cutting, thereby eliminating the defective problem of the test strip.

[0016] Furthermore, another object of the present invention is to provide a test strip cutting device for diagnostic test paper, which can be set to pass through between the first axis and the second axis composed of two blades facing each other and a spacer repeatedly arranged to guide the diagnostic test paper, so that the section through which the diagnostic test paper passes is slightly rectangular. Therefore, not only can the test strip be cut accurately, but the cut test strip will not bend or twisted.

[0017] Yet another object of the present invention is to provide a test strip cutting device for diagnostic test strips, which is configured to be able to adjust the spacing in the length direction of the shaft using adjusting screws at both ends of a first shaft supported by a thrust bearing, so that the spacing with the second shaft can be adjusted more precisely, thereby further improving the test strip cutting effect.

[0018] Technical Solution

[0019] To achieve the above-mentioned purpose, the test strip cutting device for diagnostic test paper of the present invention is preferably a test strip cutting device for diagnostic test paper that cuts a diagnostic test paper provided in a plate shape in the width direction and cuts it into multiple strip-shaped test strips at a time, comprising: a frame 100; a first shaft 200', which is formed in a disc shape, and alternately and non-rotatably clamps two blades 210' and spacers 210" facing each other and fixed, and an adjusting nut 230 is twisted and fixed on at least one side to prevent the blades 210' and spacers 210" from falling off; a second shaft 200', which is formed in a disc shape, and the blades 211 are fixed to each other. The two blades 210' and spacers 210" are alternately and non-rotatably clamped together, and an adjusting nut 230 is twisted and fixed on at least one side to prevent the blades 210' and spacers 210" from falling off; the guide member 300 is assembled on the frame 100, so that the diagnostic test paper 10 can pass through between the first shaft 200' and the second shaft 200", and supports the diagnostic test paper 10 to pass between the first guide member 300' provided on the spacer 210" of the first shaft 200' and the second guide member 300" provided on the spacer 210" of the second shaft 200" while being cut. The first shaft 200' and the second shaft 200" are rotatably mounted on the frame 100. As the first shaft 200' and the second shaft 200" rotate in situ on the frame 100, the blade 210' can cut the diagnostic test paper 10 into multiple test strips 11 by shearing force. The adjusting nut 230 mounted on the first shaft 200' and the second shaft 200" is screwed with at least two concentric adjusting screws 231 on a virtual circle with the center of the first shaft 200' as a reference, so as to push the blade 210' and the spacer 210" in the width direction to adjust the concentricity. The first guide 300' and the second The guide members 300" are designed to pass through and be sandwiched between the staggered blades 210', and protrude to form a plurality of guide strips 310. The edges of the guide strips 310 on both sides of the surfaces facing the diagnostic test strip 10 passing through the first guide member 300' and the second guide member 300" are chamfered 311 respectively. A groove 312 is formed on the guide strip 310 formed on at least one of the first guide member 300' and the second guide member 300" to prevent the sections of the test strip 10 from being pressed by the guide strips 310 when the blades 210' respectively provided on the first shaft 200' and the second shaft 200" are used.

[0020] Preferably, the blade 210 ′ is such that a first angle θ1 formed between the blade 210 ′ and a cutting edge 211 ′ formed on an edge of the blade 210 ′ is larger than a second angle θ2 formed by the blade 211 .

[0021] Furthermore, the first angle θ1 is 43° to 47°, and the second angle θ2 is 8° to 12°.

[0022] In addition, preferably, the thickness T of the portion of the guide member 300 ′ supporting the plurality of guide bars 310 is thicker than the thickness t of the guide bars 310 , and the inlet portion for inserting the diagnostic test strip 10 gradually narrows toward the inside of the diagnostic test strip 10 .

[0023] Finally, preferably, on the first shaft 200', one side is equipped with a compression spring 240, a tapered bearing 250', a bearing 250" and a thrust bearing 270 that are clamped in sequence. The thrust bearing 270 is configured to adjust its length in the longitudinal direction using an adjustment screw 271 that is rotatable on the first shaft 200'; the other side includes: a bearing 260 assembled on the first shaft 200' to support rotation and movement in the longitudinal direction; a length adjustment screw 271 assembled on the frame 100; and a thrust bearing 270 assembled on the first shaft 200' and assembled to support its rotation as the length adjustment screw 271 is rotated on the spot.

[0024] Beneficial effects

[0025] The diagnostic test paper strip cutting device according to the present invention has the following beneficial effects:

[0026] (1) A guide member is provided between two axes for cutting, so that the guide member supports both sides of the diagnostic test paper while the two blades of the blade are arranged facing each other to cut the diagnostic test paper into test strips. Therefore, the space through which the diagnostic test paper passes is formed in a slightly rectangular shape, so that the cut test strip will not be separated or twisted, thereby eliminating the problem of test strip defects;

[0027] (2) The guide member can prevent the cut test strip from being drawn into the rotation direction of the first axis or the second axis, thereby preventing the cut test strip from bending or curving, and maintaining the original rectangular column shape, so that the cut test strip is easy to place into the diagnostic kit;

[0028] (3) In this state, a groove is formed on one of the first guide member and the second guide member constituting the guide member. When the diagnostic test strip is cut by the blade, the groove prevents the diagnostic test strip from being pressed, thereby preventing the occurrence of a pressure line that may occur when the test strip is pressed by the guide member due to the force of the blade cutting. This prevents product defects and allows for more accurate understanding of diagnostic results.

[0029] (4) The guide member is chamfered on both sides of the surface facing the diagnostic test paper, thereby preventing the diagnostic test paper or test strip from being scratched or torn by the guide member when the guide member guides the diagnostic test paper;

[0030] (5) The positions of both sides of the first shaft can be adjusted in the longitudinal direction thereof, so that not only the distance between the blade formed on the second shaft and the blade can be adjusted easily, but also the adjustment can be made precisely and accurately;

[0031] (6) In addition, the adjustment screw is adjusted by screwing, so the rotation amount can be changed in the linear direction to adjust the concentricity. The concentricity of the blade can also be adjusted to 0.01mm units, so the concentricity can be adjusted precisely. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The preferred embodiments of the present invention are described in further detail below with reference to the accompanying drawings. Prior to this, the interpretation of terms and expressions used in this specification and claims is not limited to their ordinary or dictionary meanings. Instead, in accordance with the principle that the inventor may appropriately define the concepts of terms in order to best describe his or her invention, they should be interpreted according to their meanings and concepts consistent with the technical principles of the present invention.

[0063] Therefore, the embodiments described in this specification and the structures illustrated in the drawings are merely the most preferred embodiments of the present invention, rather than representing all embodiments of the technical ideas of the present invention. Therefore, when applying for the present invention, the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features therein can be replaced by equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.

[0064] [Example 1]

[0065] The diagnostic test paper strip cutting device of embodiment 1 of the present invention is as follows: Figures 1 to 10 As shown, in terms of its structure, a diagnostic test paper 10 provided in a long plate shape can be cut into a plurality of strip-shaped test strips 11 at a time along the width direction. Its structure includes a frame 100, a first shaft 200', a second shaft 200" and a guide member 300.

[0066] Furthermore, when the guide member 300 is arranged to pass through the first shaft 200' and the second shaft 200" to support the two side surfaces of the diagnostic test paper 10, the blade 211 can be rotated by the first shaft 200' and the second shaft 200" which are arranged opposite to each other and can cut the test paper strip 11 at the same time, so that the diagnostic test paper 10 is cut into the test paper strip 11 in a state where both sides are supported. Therefore, not only can the test paper strip 11 be cut according to a predetermined shape, but also the cut test paper strip 11 can be prevented from being clamped between the blades 210' as the first shaft 200' or the second shaft 200" rotates, causing twisting or failure to be cut or bent, which may occur.

[0067] The guide member 300 is provided with a groove 312 to prevent the section of the diagnostic test strip 10 that is cut by the blade from being pressed by the guide member 300. This prevents the occurrence of a pressure line when the blade 210' cuts the diagnostic test strip 10 while both sides are pressed by the guide member 300. This further prevents the problem of poor quality due to the abnormal diffusion of the reagent caused by the pressure line. In addition, the edges of the guide member 300 facing the diagnostic test strip 10 are chamfered 311 on both sides, thereby preventing damage and facilitating cutting when guiding the diagnostic test strip 10 or test strip 11.

[0068] Moreover, on the first shaft 200', the blades 211 alternately clamped and assembled on the first shaft 200' are fixed by the two facing blades 210 and the spacer 210", and at least two concentric adjustment screws 231 are screwed on the adjustment nut 230. Therefore, when the adjustment nut 230 cannot equally pressurize the blades 210' and the spacer 210", the concentric adjustment screws 231 can be used to pressurize the blades 210' and the spacer 210" to align them concentrically.

[0069] In addition, adjustment screws 271 are provided on both ends of the first shaft 200', which can be adjusted to move in the length direction of the first shaft 200', so that the blade 201' between the first shaft 200' and the second shaft 200" can be precisely engaged through adjustment.

[0070] These structures are further described in detail below with reference to the accompanying drawings. Reference numeral "10" in the drawings refers to a diagnostic test strip formed in a strip shape, with a diagnostic reagent or the like on one side, and reference numeral "11" refers to the individual test strips that are cut into multiple strips at once.

[0071] I. Framework

[0072] The frame 100 is as follows Figure 1 and Figure 2 As shown, the frame 100 supports a first shaft 200' and a second shaft 200", described later, as well as a guide member 300. A diagnostic test strip 10 is placed between the first shaft 200' and the second shaft 200", and is cut into a plurality of test strips 11. The frame 100 can be constructed in any configuration as long as it can support both ends of the first shaft 200' and the second shaft 200", with the figure showing an example of a grid configuration.

[0073] II. First and second axes

[0074] The first shaft 200' and the second shaft 20" are as follows Figures 1 to 3 As shown, the two ends of the assembly can rotate in situ on the above-mentioned frame 100, and the outer periphery is constructed with a structure that can cut a diagnostic test paper 10 into multiple test strips 11 at one time.

[0075] Here, the structures of the first shaft 200' and the second shaft 200" are the same, so the first shaft 200' is used as a reference for description, and the detailed description of the second shaft is omitted. In addition, the first shaft 200' and the second shaft 200" are as follows Figure 3 As shown, they can be configured to rotate in situ respectively, but preferably, gears 220 that can mesh with each other are respectively installed on the first shaft 200 ′ and the second shaft 200 ″ so that they rotate together and simultaneously.

[0076] To this end, the first shaft 200' is as follows Figure 2 and Figure 3 As shown, bearings 250" and 260 are provided at both ends to support the assembly so that it can rotate in place. On the periphery, the blade 211 is alternately clamped by two opposing blades 210' and spacers 210", and then the adjusting nut 230 is tightened to secure it. In this state, a keyway 280 is provided on the first shaft 200' to clamp the blades 210' and spacers 210" in place so that they cannot rotate in place.

[0077] 1. Blade

[0078] The blade 210' is, as Figures 3 to 5 As shown, it is formed in a disc shape. The blade 210' is as Figure 4 As shown, a blade 211 is provided on the edge of one side, so that the blades 210 ′ respectively mounted on the first shaft 200 ′ and the second shaft 200 ″ can cut the diagnostic test paper 10 using shear force like scissors.

[0079] In a preferred embodiment of the present invention, preferably, a cutting edge 211' is provided on the edge portion of the blade 211 on the blade 210', so that the diagnostic test paper 10 is easily cut when being cut into the test strip 11. Here, the first angle θ1 forming the cutting edge 211' is formed to be larger than the second angle θ2 forming the blade 211, so that when being cut into the test strip 11, the test strip 11 can be cut both slowly and neatly. Here, most preferably, the first angle θ1 is made to be 43 to 47 degrees, most preferably 45 degrees, and the second angle θ2 is made to be 8 to 12 degrees (most preferably 10 degrees).

[0080] Furthermore, the blade 210' is, Figure 5 As shown, a mounting hole 212 is formed through the center so as to be clamped onto the first shaft 200 ′. Another key groove 213 is formed on one side of the mounting hole 212 so that the key clamped into the key groove 280 is clamped.

[0081] The blade 210' thus formed is as follows Figure 4 As shown, the two blades 210' are brought into close contact with each other, with the blades 211 facing each other. A spacer 210" (to be described later) is brought into close contact with one side of the blades 210'. Furthermore, the two blades 210' and the spacer 210" are continuously and non-rotatably clamped and assembled on the first shaft 200'. Therefore, when the blade 210' of the present invention is used to cut the diagnostic test strip 10, the test strip is cut between the two facing blades 211 and between the facing surfaces that are not formed by the blades 211. Furthermore, both sides of the test strip 11 are cut with equal force, preventing deformation or bending of the test strip 11.

[0082] 2. Spacer

[0083] The spacer 210" is as follows Figure 3 and Figure 4 As shown, one side of the two blades 210' of the blade 211 facing each other is tightly mounted on the first shaft 200'. Furthermore, the two blades 210' and the spacer 210" of the blade 211 facing each other are formed into a unit, and multiple units are clamped into the first shaft 200' and fixed.

[0084] In this state, the spacer 210" is made into a disc shape, and its diameter is slightly smaller than that of the blade 210', ensuring space for the blade 210' to cut the diagnostic test strip 10. In addition, the spacer 210" is also assembled on the first shaft 200' in a non-rotatable manner, similar to the blade 210', so an assembly hole 212 and a keyway 213 are formed. However, these structures are the same as those described above for the blade 210' and will not be described in detail here.

[0085] In a preferred embodiment of the present invention, the spacer 210" is as follows Figure 4 As shown, when assembling the guide member 300 described later, it is most preferred to arrange the guide member 300 on the spacer 210", so that the guide member 300 can be arranged to pass through between the spacers 210" respectively arranged on the first shaft 200' and the second shaft 300", and then the diagnostic test paper 10 can be cut into test strips 11 while passing through between the guide members 300.

[0086] 3. Adjusting nut

[0087] The adjusting nut 230 is as follows Figure 3 and Figure 6 As shown, on one side of the first shaft 200', preferably, the blades 210' and spacers 210" are inserted and twisted on the first shaft 200' to support the blades 210' and spacers 210" to be fixed side by side.

[0088] Furthermore, the adjusting nut 230 is provided with at least two concentric adjusting screws 231 to pressurize the blade 210' and the spacer 210". Because, when the adjusting nut 230 is screwed on the first shaft 200', Figure 6 As shown in (b), a gap angle θ is easily generated due to the characteristics of the screw. No matter how firmly the concentric adjustment screw 231 is tightened, the possibility of the blade 210' and the spacer 210" being out of concentricity is still relatively high. If the concentricity is so inconsistent, a gap will be generated, causing the blade 210' and the spacer 210" to shake, resulting in the possibility of uneven cutting of the diagnostic test paper 10, or the possibility of the cut test paper strip 11 being sandwiched between them. Therefore, the present invention is that even if the adjustment nut 230 is not in close contact with the blade 210' and the spacer 210", the concentric adjustment screw 231 is used to make them close together while maintaining concentricity, thereby cutting the diagnostic test paper 10 into test strips 11 according to specified specifications and avoiding the occurrence of undesirable phenomena such as the cut test paper strip 11 being sandwiched between them.

[0089] In a preferred embodiment of the present invention, at least two concentric adjustment screws 231 are provided. Preferably, the spacing between adjacent screws 231 is constant. Most preferably, eight concentric adjustment screws 231 are arranged at the same spacing. Because it is impossible to determine which side will have the gap angle θ when adjusting the adjustment nut 231, the spacing between the concentric adjustment screws 231 is narrowed, allowing concentricity to be adjusted using the concentric adjustment screw 231 that is always located close together.

[0090] As described above, after adjusting the concentricity using the concentricity adjustment screw 231, the concentricity of the blade 210' can be checked and adjusted using a concentricity gauge, etc., as will be apparent to those skilled in the art. Furthermore, the concentricity adjustment screw 231 can be located only on one side of the first shaft 200', but preferably, one is located on each side. This allows for easier and more accurate concentricity adjustment due to the ability to adjust both sides.

[0091] Here, the unspecified symbol "290" is a spacer for adjusting the interval used by clamping on the first and second shafts 200' and 200". If the assembly quantity or position of the blade 210' and the spacer 210" needs to be adjusted according to the length of the diagnostic test paper 10, it can be inserted and used as needed.

[0092] III. Guide components

[0093] The guide member 300 is, for example Figure 1 、 Figure 2 、 Figure 4 and Figure 7 As shown, it is composed of a first guide member 300' and a second guide member 300", and is assembled on the above-mentioned frame 100. Furthermore, the first guide member 300' is located on the spacer 210" assembled on the above-mentioned first shaft 200', and the second guide member 300" is located on the spacer 210" assembled on the above-mentioned second shaft 200", and can be arranged to pass through these first shaft 210' and second shaft 210". A spacing setting of enough to support both sides of the diagnostic test paper 10 should be retained between these first guide members 300' and second guide members 300".

[0094] The guide member 300 is as follows Figure 4 and Figures 7 to 10 As shown, it is composed of a first guide member 300' and a second guide member 300'. The relevant structure is further described in detail below.

[0095] 1. First guide

[0096] The first guide member 300' is as follows Figure 7 and Figure 8As shown, in order to clamp one side between the blade 210 ′ assembled on the first shaft 210 ′ and the second shaft 210 ″, a plurality of support bars protrude side by side to form a plane shape.

[0097] In this state, the support bars 310 are as follows. Figure 7 and Figure 8 As shown, both sides of the edge of the surface facing the diagnostic test paper 10 are chamfered. This is because when the support bar 310 contacts the diagnostic test paper 10 for guidance, the diagnostic test paper 10 can be prevented from being scratched or damaged, thereby preventing the occurrence of poor quality.

[0098] The support bar 310 is as follows Figures 7 to 9 As shown, a groove 312 is provided on the surface facing the diagnostic test paper 10. Moreover, when the blades 210' respectively mounted on the first shaft 210' and the second shaft 210" cut the diagnostic test paper 10, the portion actually cut by the blades 210' is provided with a groove 312. Therefore, at the moment of being cut by the blades 210', the diagnostic test paper 10 can be prevented from being supported by the support bar 310, thereby avoiding the occurrence of a pressure line. In this regard, as further specifically described, Figure 9 As shown in b, if the guide strip has no groove, a pressure line is generated between the guide strip and the line cut by the blade 210' due to the pressing force of the blade 210' and the guide strip supported on the opposite side when the diagnostic test strip 10 is cut with the blade 210'. The pressure line is based on the diagnostic test strip 10. When the blade 210' is used to cut on both sides, the diagnostic test strip 10 is pressed by the cutting force and poked by the guide strip 310, thereby generating a pressure line. In the present invention, a groove 312 is formed in the portion of the diagnostic test strip 10 cut by the blade 210' respectively assembled on the first shaft 210' and the second shaft 210". Therefore, when the diagnostic test strip is cut with the blade 210', the cut portion can be prevented from being supported by the guide strip 310, thereby preventing the occurrence of a pressure line due to the guide strip 310.

[0099] The first guide member 300' is as follows Figure 8 As shown, preferably, the inlet portion between the guide bar 310 and the blade 210' that supports the diagnostic test paper 10 and allows the diagnostic test paper 10 to flow into the blade 210' is tilted inward and gradually narrows, thereby facilitating the insertion of the diagnostic test paper between the second guide member 300" and the first guide member 300' described later.

[0100] The first guide member 300' is as follows Figure 8 and Figure 9 As shown, preferably, the thickness T of the supporting portion supporting the guide strip 310 is made thicker than the thickness t of the guide strip 310 , because this can prevent the first guide member 300 ′ from being easily bent or deformed, thereby stably guiding the diagnostic test strip 10 .

[0101] Second guide member

[0102] The second guide member 300" is as follows Figure 7 and Figure 8 The figure shows the guide member that guides the diagnostic test strip 10 after placement, pushing it between the first guide members 300'. The second guide member 300' is formed alongside the guide strips 310 formed on the first guide member 300' and includes multiple guide strips 310 arranged in a staggered arrangement. This staggering ensures that the blades 210' mounted on the first shaft 200' and the second shaft 200' are staggered, allowing the guide strips 310 to pass through them.

[0103] Furthermore, the guide strip 310 formed on the second guide member 300" is as follows Figure 7 and Figure 8 As shown, preferably, a structure such as a chamfer 311 and a groove 312 formed on the first guide member 300' can be added, but the groove 312 should not be formed on the second guide member 300". Because the diagnostic test strip 10 is usually pasted with a material that can actually make the reagent easy to diffuse on one side of a component such as paper, it is preferred that a groove 312 is formed on the first guide member 300' on the surface where the material supporting the diffusion of the inducing reagent is pasted to prevent the material from being pressed, but the opposite side is hard and it is not easy to produce a pressure line, so it is not a problem if the groove 312 is not formed on the second guide member 300". Of course, the guide strip 310 formed on the second guide member 300" may also have a groove 312 like the first guide member 300'.

[0104] The guide member 300 thus formed is as follows Figure 1 As shown, except for the moment when the diagnostic test paper 10 is cut by the blade 210', support is provided from the first shaft 210' and the second shaft 210" until it is cut into the test paper strip 11. The guide member 300 is as shown in FIG. Figure 4 As shown, the diagnostic test strip 10 clamped within the chamfered rectangular space can be stably supported, allowing the blade 210' to stably cut the test strips 11. Furthermore, the cut test strips 11 are prevented from being wound around or drawn into the first and second shafts 210', 210", and discharged outside the first and second shafts 210', 210". In the portion cut by the blade 210', the diagnostic test strip 10 is not supported by the guide member, and thus no pressure line is generated.

[0105] The test strip 11 being cut while passing through the guide member 300 is not only neatly cut to the desired specifications, but also prevents the cut test strip 11 from bending or warping, thereby reducing the defect rate. The diagnostic test strip 10 is not supported by the guide member 300 at the moment of cutting. This prevents the formation of a pressure line caused by the support of the guide member 300 when the force applied to the blade 210' at the moment of cutting, thus eliminating product defects.

[0106] As described above, the present invention utilizes a guide member assembled through the first and second shafts to support both sides of the diagnostic test strip while simultaneously cutting the test strips. Therefore, not only can the diagnostic test strip be cut into strips of predetermined specifications, but the cut test strips will not be caught by the first or second shafts, thereby preventing the edges or ends of the cut test strips from becoming entangled or bent. The portion of the diagnostic test strip cut by the blade is not supported by the guide member, thereby preventing the diagnostic test strip from being pressed by the guide member due to the pressure applied by the blade, thereby preventing the occurrence of product defects.

[0107] [Example 2]

[0108] The diagnostic test paper strip cutting device of [Example 2] of the present invention is as follows: Figure 11 As shown, the structure is the same as the above-mentioned [Example 1], but the difference is that the first shaft 200' is supplemented with a structure that allows the flow to flow in the longitudinal direction. Therefore, the description here focuses on the supplementary structure, and the remaining structures that are the same as the above-mentioned [Example 1] are not described in detail.

[0109] [Example 2] is, as Figure 11 As shown, the first shaft 200 ′ can be adjusted to move along its length direction, thereby adjusting the interval between the blades 210 ′ respectively assembled on the first shaft 200 ′ and the second shaft 200 ″ to better cut the diagnostic sheet 10 .

[0110] To this end, on the first axis 200 ′, as shown in FIG. Figure 11 As shown, a tapered bearing 250' is additionally installed on at least one side so that the first shaft 200' can be stably supported even if it moves in the longitudinal direction. In this state, the tapered bearing 250' and the above-mentioned bearing 250" are preferably firmly supported and installed in the frame 100 without being squeezed backward. Furthermore, a compression spring 240 is inserted between the first shaft 200' and the tapered bearing 250'. When the first shaft 200' is pressurized in the longitudinal direction, it can provide a repulsive force in the opposite direction to act as a buffer. In addition, a thrust bearing 270 is installed at the end of the first shaft 200' to support the first shaft 200'. The thrust bearing 270 is connected to the length adjustment screw 271 installed on the frame 100 so that it can rotate in place.

[0111] Furthermore, on the first axis 200', as Figure 11 As shown, a thrust bearing 270 is assembled on the other side to support the first shaft 200'. This thrust bearing 270 is connected to the length adjustment screw 271 assembled on the frame 100. In this state, when the length adjustment screw 271 needs to be adjusted, that is, when the spacing between the blades 210' assembled 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, while pushing the thrust bearing 270 to implement the adjustment. In this state, the first shaft 200' is elastically supported by the compression spring 240, and thus is constantly buffered, allowing the length to be adjusted, and thus the spacing between the blades 210' to be adjusted. Even if the blades are offset, the buffering effect can guide them back to their original predetermined position.

[0112] As described above, the present invention utilizes a first shaft that is elastically supported and adjustable in its length. This facilitates adjustment of the blade position when necessary, ensuring stable cutting of diagnostic test strips. The elastic support provides a cushioning effect, protecting the blade and enabling accurate cutting at a predetermined position and in a predetermined configuration. Furthermore, the shaft, supported by the thrust bearing, is easily adjustable in its length, thereby facilitating adjustment of the spacing or offset between the blades disposed on the first and second shafts.
