Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a urine test tool, in particular:
This invention relates to a urine test tool suitable for testing urine samples impregnated in diapers, etc.

0002

BACKGROUND OF THE INVENTION Testing the sugar content and protein content in urine is important for health management. Various simple urine test kits are commercially available that allow this to be investigated at home. In these urine test kits, a color test reagent on a carrier is immersed in urine so that the urine sample adheres to the reagent, and then left in the air for a certain period of time. The content of sugar and protein in the urine is determined by comparing the color tone.

For example, in the case of commercially available urine test strips in which a color test reagent is printed or pasted on one side of the tip region of an elongated sheet, the opposite side of the tip region on which the color test reagent is printed or pasted is While holding the side end with your hand, insert the color test reagent area into the stream of urine while urinating, or immerse the color test reagent area into urine collected in a suitable container. A urine sample is attached to a color test reagent, left in the air, and the state of color development is examined after a certain period of time has elapsed. Alternatively, for a test kit in which a small sheet-like piece printed with a color test reagent is fixed to the inside bottom of a container, a sufficient amount of urine is poured into the container, removed, allowed to elapse for a certain period of time, and then the same procedure as above is performed. The coloration state is compared with the color tone of the standard color tone table.

[0004] As described above, when using conventional urine test kits, it was necessary to urinate during the test or to collect urine in a container for the test.

[0005]

[Problem to be solved by the invention] On the other hand, for example, in the case of infants and the elderly, it is necessary to make them urinate during the test,
Or it is not always easy to collect urine into a container for testing. In addition, even if an infant or elderly person attempts to use urine soaked in a diaper as a sample, conventional urine test kits do not have a means to press the color test reagent area against the liquid absorbent material of the diaper, so the color test is difficult. The only option was to bring the reagent area into contact with the liquid absorbent material of the diaper and then press it with a finger. In this case, there was a disadvantage that the urine also adhered to the fingers, making them dirty.

[0006] Accordingly, an object of the present invention is to provide a simple urine testing tool that does not have the above-mentioned drawbacks even when urine impregnated in a diaper or the like is used as a sample.

[0007]

[Means for Solving the Problems] The above-mentioned object of the present invention is to
A urine test tool having a color test reagent holding part and a holder part, wherein the holder part is located at a position away from the contact surface of the color test reagent support part and the urine specimen when they are brought into contact with each other. in a direction approximately perpendicular to their contact surfaces,
This can be achieved by the urine test tool described above, which is characterized in that the color test reagent holding part is provided at a position where it can be pressed against the urine sample.

The present invention also relates to a sheet for assembling a urine test device, which can be folded to form the above-mentioned urine test device.

The urine test tool of the present invention will be explained below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a urine test tool 1 which is one embodiment of the present invention. The urine test tool 1 consists of a holder part 2 and a color test reagent holding part 3. The shape of the holder part 2 may be arbitrary, and in addition to the cylindrical shape shown in FIG. 1, it can also be in the shape of a prism, a cone, a truncated cone, or the like. The color test reagent supporting portion 3 may have any shape, and may be rectangular or circular in addition to the oval shown in FIG. Further, the outer peripheries of the holder part 2 and the color test reagent holding part 3 may be formed in the shape of a seal having the same size.

As shown in FIG. 2, the color test reagent supporting section 3
For example, a color test reagent 4 for glucose, a color test reagent 5 for protein, and a sample adhesion marker 6 are supported on the bottom surface of the test tube. The number of color test reagents supported may be one, two, or three or more. Further, although not shown in FIG. 2, standard color bands can be provided near each color test reagent, so that the state of color change of the color test reagents can be compared on the spot.

[0012] In the urine test device of the present invention, conventionally known color test reagents can be used. For example, a combination of glucose oxidase, peroxidase, and ortho-tolidine can be used for glucose testing, and a combination of tetrabromophenol blue, citric acid, and sodium citrate can be used for protein testing. Other test items include occult blood (e.g. 3,
(using 3',5,5'-tetramethylbenzidine and cumene hydroperoxide), or nitrites (using, for example, N-1-naphthylethylenediamine dihydrochloride or para-arsanilic acid).

Similar to the conventional method, the color test reagent can be printed alone or mixed with a resin directly on the bottom of the color test reagent support 3, or it can be printed on a support such as paper, felt or non-woven fabric. The sheet containing the color test reagent can be attached to the bottom surface of the color test reagent support section 3 to support the color test reagent.

The sample adhesion marker 6 may include a substance that changes color when it comes into contact with urine, either alone or mixed with a resin.
A sheet printed directly on the bottom surface of the color test reagent supporting section 3, or a sheet containing a support such as paper, felt, or nonwoven fabric affixed to the bottom surface of the color test reagent supporting section 3 is used. Substances that change color when they come into contact with urine include:
For example, compounds that change color due to moisture absorption such as cobalt chloride, dyes that change color depending on the pH of urine such as methyl red, bromothymol blue, para-nitrophenol, bromophenol red, or bromocresol purple, that is, pH indicators, Powder ink etc. can be used. In particular, for compounds such as cobalt chloride that change color due to moisture absorption, it is possible to not only confirm that urine has adhered to the compound, but also to check whether the color test reagent has been denatured by moisture absorption before use. This is preferable because it can be confirmed.

[0015] If the color test reagent comes into contact with moisture (for example, moisture in the air) before conducting a urine test, accurate color development may not occur during the test, so the urine test tool of the present invention It is preferable to store (at least the color test reagent carrying part 3) in a moisture-proof bag, together with a desiccant if necessary.

When using the urine test device 1 of the present invention, hold the holder part 2 with your hand and hold the bottom surface (color test reagent supporting surface) of the color test reagent holding part 3 with an absorbent material such as a diaper. The holder part 2 presses the urine sample from above so that the urine sample sufficiently adheres to the color test reagent. After pressing, the attachment of the urine sample is confirmed using the sample attachment marker 6. If the urine sample is not sufficiently attached, repeat the pressing until it is sufficient. Next, the color test reagent holding part 3 is left in the air, and after a predetermined period of time (usually less than 1 minute) has elapsed, the degree of coloration of the test reagent is compared with the color tone of the standard color tone table. Accordingly, the concentration of the test target in the urine sample can be determined.

FIG. 3 shows one sheet for assembling a urinalysis test device, which can be folded to form the urinalysis test device by assembling the color test reagent holding part and the holder part in a predetermined three-dimensional positional relationship. Indicates the mode. As shown in FIG. 3, the assembly sheet 10 consists of a sheet 7 including a holder lower part 2a, a holder top part 2b, and a color test reagent supporting part 3. Between the holder top part 2b and the holder lower part 2a, and between the holder lower part 2a and the color test reagent supporting part 3
Folding auxiliary lines 8 are provided between the two for convenient folding. Further, the color test reagent supporting portion 3 supports, for example, a color test reagent 4 for glucose, a color test reagent 5 for protein, and a sample adhesion marker 6. The number of color test reagents supported may be one, two, or three or more. Further, although not shown in FIG. 3, standard color bands can be provided near each color test reagent, so that the state of color change of the color test reagents can be compared on the spot.

When the sheet shown in FIG. 3 is folded along the folding auxiliary line 8, a urine test tool 11 shown in FIG. 4 is obtained. The thus assembled urine test tool 11 shown in FIG. 4 can also be used in the same manner as the urine test tool 1 shown in FIG.

After the folding process, the two holder tops 2
Preferably, the holder top 2b is provided with suitable retaining means (not shown) in order to keep the holders connected and not separated from each other. For example, one holder top may be made longer than the other, and the longer holder top may be bent to provide an insertion section so that the tip of the shorter holder top can be inserted, or both. It is possible to employ a holding means that connects the tops of the holders to each other with an adhesive or an engaging member such as a clip.

[0020] It is preferable that the sheet for assembling the urine test device is also stored in a moisture-proof bag, along with a desiccant if necessary, in the same manner as the above-mentioned urine test device.

[0021] The sheet for assembling the urine test equipment of the present invention is
Instead of forming the sheet and the moisture-proof bag for storing the sheet separately, they can also be formed integrally. That is, as shown in FIG. 5, the bag integrally molded sheet 21 is formed by moisture-proofly sealing a front sheet 22 and a back sheet 23 whose surfaces have been moisture-proofed, and the cut-out line 24 and the cut-out portion 2
5. When the cut portion 25 is removed along the cut line 24, the color test reagent 4 for glucose, the color test reagent 5 for protein, and the sample attachment marker 6 provided inside the bag are exposed, as shown in FIG. The number of color test reagents provided inside the bag may be one, two, or three or more. Further, although not shown in FIG. 6, standard color bands can be provided near each color test reagent, so that the state of color change of the color test reagents can be compared on the spot. By folding the unfolded bag in this way along the folding auxiliary line (not shown) in the same manner as the sheet shown in FIG. 4, a urine test tool can be formed. It can be used in the same manner as the urine test tool 1. In addition, it is preferable to put a desiccant inside the bag of the bag-integrated sheet 21.

[0022]

Effects of the Invention According to the urine test tool of the present invention, when testing the urine of infants or the elderly, for example, there is no need to urinate during the test or to collect the urine in a container for testing. Urine impregnated into a diaper by an elderly person can be used as a sample, and the urine will not stick to the fingers and will not stain the fingers. Further, since the sheet for assembling urine test equipment and the bag integrally molded sheet of the present invention are flat, they are especially convenient for storage and disposal at home.
