Japanese Patent Laid-Open No. 7-55809

  When a test is performed using the urine test tool as described above, the user puts urine on the urine collection unit, and urine rebound may occur at that time. In this case, if the urine scatters, the urine may touch the surroundings or hands, which may cause unhealthy sensation or avoid urine jumping. The amount of collected urine was insufficient, and there was a problem that an accurate test could not be performed.

  Therefore, there has been a demand for a urine test tool that can suppress urine rebound at the time of testing, can be used in a sanitary manner, is easy to use, and can perform an accurate test.

  However, for example, in the urine test tool disclosed in Patent Document 1, urine rebound at the urine collection window is suppressed. There was room for improvement in terms of restraining the situation.

  The present invention has been made to solve such problems of the prior art, and an object thereof is to provide an easy-to-use urine test tool and container that can sufficiently suppress urine rebound.

  The urine test instrument of the present invention has a rod-shaped container, a test sheet provided inside the container, and a urine collection part provided on one end side in the longitudinal direction of the container, and is hung on the urine collection part. In the urine test device for inspecting the urine with the test sheet, the urine applied to the peripheral portion by penetrating the peripheral portion of the urine collection portion in the front-back direction which is a direction orthogonal to the longitudinal direction of the container. A urine guide hole for guiding in the direction is provided, and the urine collection part is provided on one end side in the longitudinal direction of the container in a state having a urine collection hole opened on the front side of the container, It is characterized by a taper shape that widens from the front side toward the inspection sheet side.

  The urinalysis instrument according to claim 2 of the present invention is the urinalysis instrument according to claim 1, wherein the urine guide hole is provided in a side portion of the container on the side of the urine collection unit. To do.

  The urine test device according to claim 3 of the present invention is the urine test device according to claim 2, characterized in that the urine guide holes are provided on both sides of the urine collection part.

  A urine test instrument according to claim 4 of the present invention is the urine test instrument according to any one of claims 1 to 3, wherein the urine guide hole extends in a longitudinal direction of the container.

  The urine test device according to claim 5 of the present invention is the urine test device according to any one of claims 1 to 4, wherein the container is opposite to one end side in the longitudinal direction than the urine collection unit. A step portion is formed so as to protrude on the other end side.

The urinalysis instrument according to claim 6 of the present invention is the urinalysis instrument according to claim 2 or 3 , wherein the container side portion is a portion where the urine guide hole is arranged in the container side portion. It is characterized by being formed thinner than other portions.

  The urine test device according to claim 7 of the present invention is the urine test device according to any one of claims 1 to 6, wherein the urine collection hole is a slit extending in the longitudinal direction, and the urine collection unit includes the urine collection unit. A plurality of the slits are arranged in the width direction of the slit.

Rod-like container according to claim 8 of the present invention is a rod-like container definitive urinalysis instrument according to any one of claims 1 to 7, the front piece having a urine collecting part, fitted to the front piece A urine collection hole is formed in the urine collection part, and at least one side of both sides of the urine collection part in the width direction of the container perpendicular to the longitudinal direction of the container is provided on the front side piece. A urine guide hole penetrating in the front and back direction is formed, and the urine collection hole has a tapered shape that spreads from the front side to the back side of the front side piece.

  In the case of the present invention, the peripheral portion of the urine collection portion is provided with a urine guide hole for guiding the urine applied to the peripheral portion in the front and back direction of the container (the direction in which the urine is applied). Urine is guided toward the front and back of the container through the urine guide hole. Therefore, bounce of urine can be sufficiently suppressed, and usability can be improved. The urine guide hole is provided on the side of the container on the side of the urine collection part. Here, the side refers to the width direction of the container orthogonal to the longitudinal direction of the container, and the container side portion refers to a portion close to the end of the container in the width direction. In particular, by providing the urine guide holes on both sides of the urine collection part as in claim 3, it becomes possible to suppress the urine bounce and scattering on both sides of the urine collection part, and the usability can be further improved. Furthermore, it becomes possible to suppress the urine that has circulated to one side of the back side of the container from being scattered from the opposite side, and the usability can be further improved. The urine guide hole preferably extends in the longitudinal direction of the container as in claim 4 in consideration of the shape of the container. In other words, by opening the urine guide hole long in the longitudinal direction of the container, it becomes possible to enlarge the urine guide hole itself while restricting the width dimension of the container effective for suppressing the urine rebound. Can be suppressed.

  Furthermore, in the case of the invention of claim 5, the step portion functions as a barrier, and urine rebounding to the other end side (side held by the hand) than the step portion can be suppressed. Can be improved.

  Furthermore, in the case of the invention according to claim 6, the container side portion provided with the urine guide hole is connected to the portion where the urine guide hole is arranged in the other portion of the container side portion (in the container side portion). Since the thickness in the front and back direction is thinner than the portion other than the urine induction hole), the urine passage length of the urine induction hole can be shortened, and thereby, the distance between the urine induction hole and the urine The resistance becomes small and urine can easily escape. As an example, when the urine guide hole is composed of a front side piece and a back side piece, the urine passage length of the urine guide hole is increased and resistance increases, making it difficult for urine to escape. In the case of the configuration, the urine guide hole is shortened, the resistance to the urine is reduced, and the urine can be more easily escaped.

  Furthermore, according to the invention of claim 7, since the urine collection hole is formed in a slit shape and a plurality of urine collection parts are arranged in the width direction of the slit, the area ratio of the urine collection hole to the urine collection part can be increased. This is because, for example, when a large number of round holes are provided, a partition (meat portion) is required between adjacent holes, but when a plurality of slits are provided in parallel, the number of partitions can be reduced. . With this configuration, urine rebound can be effectively suppressed, and the amount of urine necessary for testing can be collected in a short time, leading to improved usability.

Furthermore, in the case of the bar-shaped container according to the invention of claim 8, since the front side piece and the back side piece are manufactured separately, the members disposed in the container, such as the inspection object, are arranged on the front side piece and the back side. A urinalysis instrument can be easily formed by arranging the front side piece and the back side piece in one of the pieces.

  The present invention will be specifically described below.

  The urine test device of the present invention is composed of a rod-shaped container for a urine test device and a test tool accommodated in the container. Moreover, you may have a cap detachably attached to the one end side or both ends side in the longitudinal direction of this container as needed.

  The container is composed of a front side piece and a back side piece, and can be used by being assembled with each other by fitting them together. Alternatively, integral molding may be used. As the cap and the container, a known material such as a resin material such as plastic or elastomer can be used, and can be appropriately selected according to the purpose such as transparency, opacity, moldability, strength, and the like.

  The urinalysis instrument of the present invention includes at least a urine collection unit, a determination display unit, and a grip unit. Here, as one form of the urine collection unit, the urine test instrument is provided on one end side in the longitudinal direction of the container in which urine is collected during use and has a urine collection hole. The container is provided with a urine collection hole, a urine guide part, and the like. Further, a urine absorber for a test sheet described later is accommodated in the container. When using the urine test device, urine is applied to the urine collection part, so that the urine as the test object is taken into the urine absorber attached to the test sheet from the urine collection hole and used for the test. It becomes. As another form, there is a urine test device that is provided on one end side in the longitudinal direction of the container where urine is poured during use, and the urine absorber is disposed in a state where most of the urine absorber is exposed from the container. In the case of this form, the urine absorber is provided with a urine guide part, and a reaction member (test body) of a test sheet described later is accommodated in the container. At the time of use of the urine test device, urine is applied to the urine collection unit, so that urine, which is a test object, is taken into the test sheet and used for the test.

  The urine collection hole is provided in the front side piece of the container. The shape of the urine collection hole is not particularly limited as long as urine is taken into the urine absorber. For example, as shown in FIG. 10, one urine collection hole 28A may be formed in the urine collection unit 20, or one rectangular hole may be formed (24 in FIG. 10 represents a urine induction hole). . Alternatively, a net-like urine collection hole 28B shown in FIG. 11 and a large number of dot-like urine collection holes 28C shown in FIG. Alternatively, a plurality of oblong urine collection holes 28D are arranged side by side as shown in FIG. 13, and the same urine collection holes 28E are arranged side by side as shown in FIG. 14, or similar urine collection holes are provided. For example, the urine collection holes may be rectangular instead of the elliptical shape. Furthermore, these may be combined. In addition, from the viewpoint of suppressing urine bounce, it is preferable to arrange a plurality of slit-shaped (fence-shaped) urine collection holes in the width direction of the slit. Thus, when the urine collection holes are formed in a slit shape, the interval between the parallel arrangements is narrow, and the larger the number, the higher the area ratio of the urine collection holes to the urine collection part, thereby improving the efficiency of urine collection. Thus, urine rebound is further suppressed. However, depending on the material of the container, there is a possibility that molding may be difficult or a problem may occur in strength. Moreover, when considering the function as a support member of the test body accommodated in the container, since the press is insufficient, the test body may be misaligned, and the function as the test drug may be impaired. Therefore, it is preferable to appropriately select the shape and number of the urine collection holes in consideration of the suppression of urine bounce and the function as the test object.

  Further, by providing a step portion in the vicinity of the urine collection hole of the container front side piece, the step portion functions as a barrier when the boiled urine scatters in the direction of the hand, and the other end side of the container (hand) This contributes to preventing the urine from bouncing back to the side. As a result, a situation in which the amount of urine collected at the urine collection unit becomes insufficient in order to avoid rebound of the urine can be avoided, leading to an improvement in examination accuracy. Note that the shape and height of the stepped portion can be appropriately selected in consideration of design and functionality.

  The urine guide part is provided on at least one side of the container side part (7c in the embodiment of the present invention) on the side of the urine collection part of the urine test instrument in the present invention. As a form of the urine guide part, any form that guides urine in a specific direction may be used. Specific examples include the following three.

-It must be a cutout shape-It must be a through-hole-A combination of the above The cutout shape refers to a shape in which the urine collection part is partially cut away, for example, as shown in FIG. This corresponds to a cutout portion (urine guide portion) 24D that is partially cut off. Of course, the notch (urine guiding part) can be provided only on one side 7c of the container. Further, as described above, in the urine test device in which the urine absorber is disposed in a state where most of the urine absorber is exposed from the container, the above-described notch (urine) is directly applied to the exposed portion of the urine absorber. (Guidance part) can be provided.

  As the through hole (urine guide part), various shapes can be adopted, for example, a dot-like through hole 24A shown in FIG. 15, a slit-like urine guide part 24 shown in FIG. About the opening length at the time of setting it as a slit, it can select suitably. Further, as shown in FIGS. 16 and 17, through holes 24B and 24C having two or more slits having different sizes may be used. Moreover, as shown in FIG. 24, you may use the shape along the peripheral part of the urine collection part 20, for example, the substantially U-shaped through-hole 24F. The through-hole 24F of the urine test instrument 1D shown in FIG. 24 is a curved hole 24F3 provided at one end side 7a of the two holes 24F1 and 24F2 provided on the side parts 7c on both sides, and provided at the tip 7d. It is a connected shape. The through hole 24F has a configuration in which the holes 24F1 and 24F2 on both sides are omitted and only the hole 24F3 on the tip 7d is provided, or the holes 24F1 and 24F2 on both sides are omitted and only the tip 7d has a through hole. It is good also as a form which provided (for example, circular or rectangular through-holes). In addition, 28F in FIG. 24 is a urine collection hole. Furthermore, as shown in FIG. 25, the surrounding member 53 is provided so as to surround the exposed portion 42a of the urine absorber 42, and urine having a configuration in which a gap between the surrounding member 53 and the exposed portion 42a is arranged as a through hole 24G. The inspection tool 1E may be used. The surrounding member 53 is bent halfway and has a shape in which both ends are located on the opposite side of the bent portion, and both ends are connected to the container.

  Combining both of the above means that, for example, a through hole is provided in the front side piece, the corresponding part of the back side piece is cut out, and these are combined (that is, the urine guide part is provided only on the front side piece) or vice versa. In addition, a through hole is provided in the back side piece, and the corresponding part of the front side piece is cut out, and these are combined (that is, the urine guide part is provided only in the back side piece), or the through hole and the cut portion are cut in the longitudinal direction of the container. This refers to arranging a part having a notch shape (for example, a notch part 24D described later). In addition, when arranging the through-hole and the notch-shaped portion side by side in the longitudinal direction of the container described above, when the container-side side portion 7c of the back side piece is notched, the through-hole and the notch are formed with respect to the front side piece. When the shape-side portions are arranged side by side and the container-side side portion 7c of the front-side piece is cut out, the through-hole and the cut-out portion are arranged side by side with respect to the back-side piece, and the front-side piece and the back-side piece container When the side portion 7c is not a notch shape, the front side piece and the back side piece are provided with a through-hole and a notch-shaped portion arranged side by side.

  In addition, as for the formation position of the urine guide part, if it is the container side part of the urinalysis instrument, the urine guide part 24 (24A, 24B, 24C, 24D) is provided on one container side part 7c as shown in FIG. However, it is more preferable to provide both sides (7c and 7c in the embodiments of the present invention) of the side portion of the container. The same applies to the case where the urine guide part is formed on the exposed part of the urine absorber.

  As described above, the urine guide portion can be selected to have a notch shape, to provide a through hole, or to combine them. In this case, in order to increase the inductivity of urine, it is preferable that the thickness of the container in the front and back direction is formed thin. Further, in order to more effectively suppress the urine rebound while ensuring the urine inductivity, as shown in FIG. 20, the portion outside the urine guide hole (urine guide portion) 24 on the side of the container. 26 may be provided with a step 26a to increase the surface area, or may be provided with a groove in place of the step 26a to increase the surface area.

  The determination display section is preferably provided with a determination window in order to make the determination result after inspection clear. The number and shape of the determination windows can be appropriately selected depending on the display mode of the determination results. Moreover, in order to make visual recognition easy, the resin film etc. which block | close the determination window have a transparent or semi-transparent thing.

  In order to improve the usability, the grip portion may be subjected to anti-slip processing such as unevenness as necessary.

  As described above, the urine test instrument of the present invention is composed of the container composed of the front side piece and the back side piece and the test body in the container, but the front side piece and the test body need not necessarily be in close contact with each other in the sectional structure. Alternatively, an appropriate space (gap) may be provided between them. For example, in the case of a test using a simple reaction system such as confirming a change in color tone due to pH, by providing the space, urine, which is a test sample accommodated in the urine absorber, develops on the test object. The development at the time becomes smooth and the inspection can be performed more speedily. On the other hand, for example, in the case of a test using the principle of immunochromatography, it is necessary to ensure a sufficient reaction time between urine, which is a test sample, and an antibody. In that case, the development speed of the test specimen can be adjusted by bringing the front side piece and the test body into close contact with each other. Furthermore, a protrusion member, a pressing member, and the like for fixing the test body sandwiched between the front side piece and the back side piece, that is, the inner surface when the container is assembled, can be provided as necessary. By adding such a member such as a protruding member to the configuration, it is possible to adjust the flow path when the test specimen absorbed by the urine absorber is deployed, and to finely adjust the deployment speed. This is also useful from the viewpoint of improving inspection accuracy and reproducibility.

  In the urine test instrument of the present invention, the test substance existing in the urine absorbed by the urine absorber is transferred to the reaction member by capillarity using at least a test body composed of the urine absorber and the reaction member. Then, identification, inspection, and judgment are performed.

  Furthermore, the urine test device of the present invention can perform various tests on urine as a test target. Specific examples include various hormones such as hCG and hLH, pH, glucose, protein, occult blood, and the like.

  As a test sheet, for example, a urine absorber, a reaction member, and a water-absorbing filter paper are arranged in order from one end side (7a in the embodiment of the present invention) on a base sheet formed in a strip shape. Yes. If necessary, the urine absorber may be provided with a color changing means such as a chemical species that changes color in response to urine, a pH indicator, or the urine movement adjusting body is provided between the urine absorber and the reaction member. It may be interposed, and a desiccant may be attached to the water-absorbing filter paper. In particular, when performing tests using immunochromatography, it is necessary to secure a reaction time between the test substance and the monoclonal antibody according to the test target. It is good to provide.

  Note that the specimen may be composed of a single chromatographic medium or may have several types of chromatographic media in the development direction. The latter specimens include those in which several types of chromatographic media are directly connected, or those in which a short chromatographic medium is partially attached to another long chromatographic medium, or several types of chromatographs. The medium may be connected by another chromatographic medium.

  As a material used for each member of the urine test instrument of the present invention, a known material can be appropriately used depending on the purpose of the examination, the object to be examined and the like. Specific examples include the following.

  Nitrocellulose, a glass filter or the like is used as the base sheet. Non-woven fabrics and the like as urine absorbers, non-woven fabrics and glass fibers as urine movement regulators, and various filter papers (qualitative filter paper, quantitative filter paper, liquid separation filter paper, glass fiber filter paper, silica fiber filter paper, Composed of composite fibers, etc.) and various non-woven fabrics. Also, these materials are interchangeable and can be used for other members.

The urine collection part 20 is arranged on one end side 7a in the longitudinal direction, and urine guide holes 24 penetrating the container side side parts 7c on both sides (the width direction of the container 7 orthogonal to the longitudinal direction) sandwiching the urine collection part 20 are formed. The determination display window 22 is arranged on the other end side 7b from the urine collection unit 20. The urine collection unit 20 is covered with the cap 5 by attaching the cap 5 to the one end side 7a of the container 7 as described above.

  The back side piece 11 is formed so as to have substantially the same shape as the front side piece 9 except for the one end side 7a, and the width W1 (see FIG. 4) of the one end side 7a of the back side piece 11 is the same as that of the front side piece 9. The width dimension W2 (≈W1) sandwiched between both urine guide holes 24 (see FIG. 3) is substantially the same. Therefore, the urine guide hole 24 is constituted only by the front side piece 9. And the urine guide hole 24 is formed so that it becomes shallow by comprising the urine guide hole 24 only by the front side piece 9 in this way.

  Further, the urine guide hole 24 penetrates in the front and back direction of the container 7 and is long in the longitudinal direction of the container 7 and is formed close to the outer side in the width direction of the container 7, from the urine guide hole 24 to the urine collection part 20. The distance from the urine guide hole 24 to the outer side in the width direction of the container 7 is shorter than the distance, and the portion outside the width direction from the urine guide hole 24 is a thin-walled portion 26 in the width direction.

  The urine collection section 20 is formed with three slits 28 as urine collection holes penetrating in the front and back direction of the front side piece 9, and is formed in a fence shape arranged in parallel in the width direction of the slit 28.

Each slit 28 is long in the longitudinal direction of the container 7 and is formed in the same manner, and is formed longer than the urine guide hole 24. On both sides of the slit 28 in the width direction, a slit forming portion 29 protruding toward the back side piece 11 is provided, and the side surface 30 on the slit 28 side of the slit forming portion 29 is located on the inner back side of the slit 28. The width W3 is formed in a tapered shape with the outer surface side of the slit 28 having a narrow width W4 (<W3) (see FIG. 6).

  Further, the front side piece 9 is formed with a stepped portion 32 that protrudes outward from the urine collection unit 20 between the urine collection unit 20 and the determination display window 22 and in the vicinity of the urine collection unit 20. The step portion 32 is formed such that the urine collection portion 20 side (one end side 7a) is steep. The end of the other end side 7 b of the urine guide hole 24 is located in the vicinity of the stepped portion 32. The determination display window 22 is closed with a transparent resin film 22a. The resin film 22a may be translucent.

  Further, on the stepped portion 32 side (the other end side 7 b) of the urine collection unit 20 and on the inner surface side of the urine collection unit 20, a projecting portion 34 projecting toward the test sheet 40 side is formed (see FIG. 8). ). The protrusion 34 is formed so that the inspection sheet 40 side is flat and the inner side of the three slits 28 is closed, and urine that has hit the outside of the protrusion 34 is once returned to the one end side 7a. It has the function to move to the back side of the protrusion part 34 later, and to move to the other end side 7b after that, ie, to detour.

  A pressing portion 36 that protrudes further toward the back piece 11 than the other portion is formed at the one end side 7 a of the protruding portion 34. This pressing part 36 is for adjusting the movement of urine by pressing a urine movement adjusting body 43 described later. The protruding height dimension of the pressing portion 36 is appropriately selected according to the thickness dimension of the urine movement adjusting body 43 and the like. Further, a connecting portion 38 is formed on one end side 7 a of the urine collecting portion 20 so as to close the back side piece 11 side of the slit 28.

  The test sheet 40 includes a urine absorber 42, a urine movement adjusting body 43, a reaction member (test body) 44, and a water absorption filter paper 45 arranged in this order from the one end side 7a on a base sheet 41. . The end of one end side 7 a of the urine movement adjusting body 43 is sandwiched between the base sheet 41 and the end of the other end side 7 b of the urine absorber 42, and the other end side 7 b of the urine movement adjusting body 43 is The end of one end side 7 a of the reaction member 44 is sandwiched between the end portion and the base sheet 41, and the end of the other end side 7 b of the reaction member 44 is connected to the end of the one end side 7 a of the water absorbent filter paper 45 and the base. It is sandwiched between the sheet 41. In addition, a desiccant may be provided separately.

  In the first embodiment, the base sheet 41 is formed of a nitrocellulose sheet. The urine movement adjusting body 43 is made of glass fiber, and the test substance is labeled here. The urine absorber 42 is formed of a non-woven fabric. The urine absorber 42 together with the slit 28 takes urine into the container 7 and supplies it to the test body (reaction member) 44 via the urine movement adjusting body 43. It constitutes the urine collection part. In addition, the inner surface of the slit forming portion 29 provided on both sides of the slit 28 is in close contact with the urine absorber 42. Further, the inner surface of the pressing portion 36 is in close contact with the urine movement adjusting body 43. Since the slit forming part 29 and the protruding part 34 on which the pressing part 36 is formed are connected to each other, the gap between the slit 28 and the inspection sheet 40 is one of four directions in the longitudinal direction and the width direction of the slit 28. The three directions are closed, and only one end side 7a is open.

  In the present embodiment, the test body (reaction member) 44 detects urinary human luteinizing hormone (hLH), and is tested for positive or negative based on the coloring pattern. The urine movement adjusting body 43 is appropriately selected in material or the like according to the test object, that is, according to the type of the test body to be used.

  And as above-mentioned, while the inner surface of the press part 36 is closely_contact | adhered to the urine movement adjustment body 43, since the side surface 30 of the both sides which pinches | interposes the slit 28 is formed in the taper shape, there exist the following effects.

  That is, since the side surface 30 on the slit side in the slit forming portion 29 on both sides of the slit 28 is formed in a taper shape with the inner side of the slit having a wide width W3 and the outer surface side of the slit having a narrow width W4, it enters from the slit 28. The reverse flow (return) to the outside of the urine is blocked to make it difficult to collide with the urine entering the slit 28, thereby reducing the urine splash. This effect can be obtained by bringing the inner surface of the slit forming portion 29 sandwiching the slit 28 in the width direction into close contact with the urine absorber 42 provided inside the urine collection portion 20 as described above. On the other hand, since there is no gap between the slit forming portion 29 and the urine absorber 42 when the contact is made in this way, the number of urine collection points is reduced, and the urine that has entered from the slit 28 passes through the urine absorber 42. It becomes easy to move to the body 44, and the time required for the reaction with the inspection body 44 cannot be secured. However, since the slit-side side surfaces 30 of the slit forming portions 29 on both sides of the slit 28 are formed in the above-described taper shape, the movement of the urine entering the slit 28 from the urine absorber 42 to the test body 44 is delayed. Thus, the moving speed of urine can be controlled. Thereby, it becomes possible to make the moving speed of the urine supplied to the test body 44 appropriate, and it becomes possible to secure the time required for the reaction with the test body 44, thereby improving the test accuracy. It becomes possible to make it. Therefore, the side surface 30 on the slit side in the slit forming portion 29 is formed in the above-described taper shape, and the inner surface of the slit forming portion 29 is brought into close contact with the urine absorber 42, thereby reducing urine rebound and improving inspection accuracy. It is possible to achieve both.

  Instead of the configuration described above, when the slit forming portion 29 is separated from the urine absorber 42 and a gap is formed between the slit forming portion 29 and the urine absorber 42, it is difficult for urine to enter the slit 28. Urine rebound becomes noticeable. Similarly, when the inner surface of the slit forming part 29 is closely attached to the urine absorber 42 and the side surfaces 30 on the slit side in the slit forming parts 29 on both sides of the slit 28 are formed in a tapered shape opposite to the above, When reverse flow of urine occurs from the slit 28 to the outside, the reverse tapered side surface described above facilitates the reverse flow, so that it collides with the urine entering the slit 28 and the urine rebounds easily.

  The examination contents in the urinalysis instrument 1 according to the first embodiment configured as described above will be described.

  The cap 5 of the urine test device 1 in the standby state shown in FIG. 9A is removed from the urine test device main body 3 and attached to the other end side 7b of the container 7 as shown in FIG. 9B. As a result, the urine collection unit 20 and the urine guide hole 24 are exposed, and the entire length of the urine test tool 1 is increased.

  Thereafter, the cap 5 attached to the other end 7b of the container 7 is positioned on the upper side and gripped, and the urine is applied to the urine collection unit 20 positioned on the lower side. As a result, urine is applied to the urine collection unit 20 and urine is absorbed by the urine absorber 42. Moreover, since the urine guide hole 24 is formed in the container side part 7c on both sides of the urine collection part 20, the urine hung on the container side part 7c passes through the urine guide hole 24 in a specific direction, for example, urine It is guided in the depth direction of the guide hole 24 or the direction in which urine flies. Therefore, urine rebound (or rebound) is sufficiently suppressed, and usability is improved.

  Furthermore, since the total length of the urine test device 1 is increased by attaching the cap 5 to the other end side 7b of the container 7 as described above, the length from the cap 5 held by hand to the urine collection unit 20 is increased. It is possible to increase the distance between the portion gripped by the hand and the urine collection unit 20 which is a portion on which urine is applied.

  Further, the urine guide hole 24 is formed long in the longitudinal direction of the rod-like container 7. That is, by making the urine guide hole 24 longer in the longitudinal direction, it is possible to enlarge the urine guide hole 24 itself while restricting the width dimension of the container 7 effective for suppressing the urine rebound. Therefore, it is possible to suppress urine rebound. In addition, as described above, the container width direction outer side portion of the urine guide hole 24 is a thin-walled portion 26, and the thickness of the meat portion 26 is 1.0 mm in this embodiment. Rebounding is suppressed. In addition, as thickness of the meat part 26, 0.1 mm or more and 10 mm or less are preferable. The reason is that when the thickness is smaller than 0.1 mm, the strength of the meat portion 26 is lowered and is easily damaged, and conversely, when the thickness is larger than 10 mm, it is difficult to obtain the effect of suppressing the urine rebound. Because it becomes.

  Further, the stepped portion 32 contributes to preventing the urine from bouncing back to the other end side (side held by hand) 7b than the urine collecting portion 20, so that the usability can be further improved. The stepped portion 32 may be separated from the urine collecting portion 20 instead of being arranged in the vicinity of the urine collecting portion 20, and the distance between the two is adjusted according to the protruding height of the stepped portion 32 outward. The value may be determined empirically (approaching or separating) and a value that can prevent the urine from rebounding to the other end side (side held by hand) 7b.

  Furthermore, since the three slits 28 are provided in the width direction of the slit 28 in the urine collection part 20, the area ratio of the slits (urine collection holes) to the urine collection part 20 can be increased, and the urine collection holes are collected. It is possible to increase the amount of urine within a range necessary for the examination, and this can also suppress the urine bounce. Further, the thickness of the slit forming portion 29 that sandwiches the slit 28 in the width direction can be set to an appropriate size, thereby making the formability of the container 7 difficult and reducing the strength of the slit forming portion 29. Can be suppressed.

  Furthermore, since the urine guide hole 24 is formed only by the front side piece 9, it is possible to make it easier to pass through urine than when the front side piece 9 and the back side piece 11 are used. That is, when the urine guide hole 24 is constituted by the front side piece 9 and the back side piece 11, the urine guide hole becomes deep and resistance between the urine and the urine becomes difficult to pass through, but as in the first embodiment. In the case where the urine guide hole 24 is constituted by only the front side piece 9, the urine guide hole 24 becomes shallow, the resistance between the urine and the urine is reduced, and it is possible to easily pass through the urine.

  In the first embodiment described above, the urine guide holes are provided in both of the side portions of the container on the side of the urine collection unit 20. However, the present invention is not limited to this, and one side of the urine collection unit 20 is provided. You may make it the structure which provided the urine guide hole in the container side part. In addition, the urine guide hole includes a form in which a plurality of urine guide holes are arranged side by side in the longitudinal direction of the container, rather than a form in which one long in the longitudinal direction of the container is provided on one side of the container.

  In the first embodiment described above, the urine collection unit 20 is provided with three slits (urine collection holes) 28, but the present invention is not limited to this. For example, you may make it provide the slit (urine collection hole) of a suitable magnitude | size in the urine collection part 20 by 1 or 2 or 4 or more. In this way, for example, it is possible to correspond to the size of the urine collection unit, the amount of urine collected, and the like.

(Second Embodiment)
FIG. 21 is a plan view showing a urine test instrument according to the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same part as the urine test tool of 1st Embodiment.

  This urinalysis instrument 1A uses a container 50 in which one end side is omitted from the step portion 32 of the front side piece and the back side piece, and the urine absorber 42 is arranged in a state where most of the urine absorber 42 is exposed from the container 50. It is installed. The exposed portion 42a of the urine absorber 42 is used as a urine collecting portion on which urine is applied, and a urine guiding portion 51 is provided on a side portion on the side (width direction) of the exposed portion 42a. The urine guide part 51 is provided on both sides of the exposed part 42a, and is formed as a urine guide hole that penetrates the exposed part 42a in the direction in which urine is applied.

  Therefore, even in the second embodiment, urine applied to the side portion of the exposed portion 42a of the urine absorber 42 is guided in a specific direction via the urine guide portion (urine guide hole) 51. Can be sufficiently suppressed, and usability can be improved. At this time, since the urine guide portions 51 are provided on both sides of the exposed portion 42a of the urine absorber 42, it is possible to suppress urine rebound and scatter on both sides of the urine collection portion, and usability can be further improved. Further, since the urine guide part (urine guide hole) 51 is formed to be long in the longitudinal direction of the container 50, the width dimension of the urine absorber exposed part effective for suppressing the urine bounce is regulated. The urine guide hole itself can be enlarged while suppressing the urine rebound. Furthermore, since the stepped portion 32 remains, the stepped portion 32 functions as a barrier and can suppress the urine bounce back to the other end side (side held by hand) 7b from the stepped portion 32. Usability can be further improved. Note that the urine guide part 51 may be provided on one side of the side part of the exposed part 42a. Moreover, as a urine guide part provided in the exposed part 42a of the urine absorber 42, it is long in the longitudinal direction of the container 50 and has one end side (the other end side 7b) in the longitudinal direction as in the urine test tool 1C shown in FIG. A urine guide part (urine guide hole) 51A having an opening on the edge of the exposed part 42a may be used.

  As shown in FIG. 22, it is preferable to form a concavo-convex portion 52 at a portion sandwiched between the urine guiding portions 51 on both sides in the exposed portion 42a. The uneven portion 52 has a function of increasing the surface area due to the unevenness and increasing the amount of urine absorbed, and the amount of urine absorbed can be controlled by the size of the surface area accompanying the unevenness. Further, the unevenness portion 52 can control the amount of urine absorption even in accordance with the material of the urine absorber 42. As the shape of the concavo-convex portion 52, two long rectangular shapes are employed in FIG. 22, but any shape can be selected as the shape of the concavo-convex portion 52. As an example, for example, one oval shape, a mesh shape, a shape including a large number of dots, a plurality of ellipse shapes, and a plurality of oblique long holes (FIG. 10), which are shapes used for the urine collection holes 28A to 28E. (See FIG. 14).

  Table 1 is a table summarizing observation results of urine splashing (bounce back). In addition, Example 1 is a thing by the case where it is based on the urine test device which concerns on 1st Embodiment mentioned above, Example 2 is a comparative example, when it is based on the urine test device 1A which concerns on 2nd Embodiment shown in FIG. 21 mentioned above. 1 is a case of using a urine test device provided with three slits (urine collection hole) in the urine collection part but omitting the urine induction hole (urine induction part). In Comparative Example 2, the urine collection part exposes most of the urine absorber. This is a case of using a urinalysis instrument that is a urine test tool that omits the urine guide hole (urine guide part).

  As can be seen from Table 1, in both Comparative Example 1 and Comparative Example 2, splashing was mainly observed in the left and right directions, but in the case of Examples 1 and 2 of the present application, almost splashing was observed. Was not observed.

  Table 2 shows the results of investigating the amount of urine necessary for the test. In addition, Example 1 and Comparative Example 2 are the same as those in Table 1, and these urine test devices are set in a state inclined by 45 ° with respect to a horizontal plane, and are orthogonal to the urine test device in that state. From the direction, water was applied as a substitute for urine at a flow rate of 15 mL / sec. Then, the time for applying water was changed to 0.5 seconds, 1 second, 2 seconds, 3 seconds, and 5 seconds, and it was investigated whether the movement of water had any problem in the inspection.

  As understood from Table 2, in the case of Comparative Example 2, the inspection becomes difficult when the application time is short, but in the case of Example 1 of the present application, the inspection can be performed without trouble from 0.5 seconds. You can see that it can be done.

  In the second embodiment described above, most of the urine absorber 42 is exposed as the exposed portion 42a. However, the present invention is not limited to this. For example, as long as it can function as a urine collection unit, it may be a part or the whole.

  Moreover, in 2nd Embodiment mentioned above, although it has set it as the structure which made the container 50 remove one end side rather than the level | step-difference part 32 in both a front side piece and a back side piece, this invention is not limited to this, Only a front side piece One end side may be omitted from the stepped portion 32, and the back side piece may be left to one end side. However, it is required to adjust the width dimension narrowly so that urine can pass through the urine guide 51.

  Furthermore, in the first and second embodiments described above, the present invention is applied to a urinalysis instrument that detects urinary human luteinizing hormone (hLH) and human chorionic gonadotropin (hCG). The present invention is not limited to this, and can be applied to various tests in which urine is a test target. In such application, the configuration of the inspection sheet is appropriately adjusted.

  Furthermore, in the first and second embodiments described above, the present invention is applied to a urine test instrument having a cap. However, the present invention is not limited to this, and can also be applied to a urine test instrument in which a cap is omitted. It is.
