CONSTITUTION:A specimen take-out jig 2 has a syringe shape and, when the upper expansible part 2-1 thereof is engaged with the opening part of a con tainer 1, said expansible part 2-1 becomes a plug to receive the specimen take- out jig 2 in the container 1 in a hermetically sealed state. By this method, the hygroscopicity of a highly water absorbable compound 4 before use can be prevented. Next, in use, air is escaped from a hole 2-2 to the outside to close the hole 2-2 by a finger and, when pressure is released to generate sucking action, a gel-like specimen swollen by the absorption of urine is sucked in the tubular part 2-3 of the spuit from the opening part of the lower part of the tubular part and collected. Subsequently, the collected specimen can be efficiently taken out by a necessary amount without contaminating a hand by strongly pressing the expansible part 2-1 while closing the hole 2-2 by a finger.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a urine testing tool that facilitates urine collection, prevents the occurrence of bad odors, is hygienic, and is convenient for transportation, storage, and sample extraction.

[Conventional technology]

In recent years, urine tests have been increasingly used as a means of obtaining important information regarding the functions of the kidneys, liver, etc., as well as blood conditions, diabetes, hypertension, and the like.

However, despite advances in testing and analysis technology, urine collection and storage methods remain outdated, with the old method of having the patient collect urine in a pot and storing it on a designated shelf. . As a result, the area around the shelf is filled with bad odor, which causes discomfort to people, and also poses a storage problem, as well as hygienic problems as urine spills around the area.

In addition, when transporting the urine to the laboratory or removing the specimen, it often spills or adheres to clothing, and there are also problems in that the locations for urine collection are limited.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems associated with urine collection, which is essential for urine tests, namely, the bad odor of the urine sample storage area, storage problems, hygiene problems, and limited urine collection locations. and difficult to transport,
This was done with the aim of solving the problem of troublesome specimen extraction.

[Means for solving problems]

As a result of various studies to achieve this objective, the inventor has found that
The present invention was made based on the discovery that the above-mentioned problems could be solved all at once by devising the structure of the container and using a highly water-absorbing compound.

That is, the present invention comprises a urine collection tool for collecting, holding urine, and taking out a specimen, and a container for sealing the urine collection tool, and the urine collection tool includes a dropper-like specimen retrieval tool whose upper inflated part serves as a stopper for the container. The present invention provides a urine test tool comprising a urine collection holder which is removably fitted into the specimen retrieval tool, houses a highly water-absorbing compound, and has one or more urine collection holes. be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The urinalysis tool of the present invention will be described below with reference to drawings of one embodiment.

FIG. 1 is a vertical cross-sectional view of the urinalysis tool of the present invention. In the figure, 1 is a storage container for a urine collection tool, 2 is a sample extraction tool, 3 is a urine collection holder, and the combination of 2 and 3 is the urine collection tool.

The specimen extractor 2 is in the shape of a dropper, and when the upper inflatable part 2-1 is fitted into the opening of the container 1, it becomes a stopper and is stored in the container 1 in a sealed state.

This can prevent moisture or water absorption of the highly water-absorbing compound described later in the used moe, and also has the effect that storage and transportation after urine absorption becomes extremely easy.

The material of 1 is not particularly limited, but may include plastics, such as olefin resins such as polyethylene and polypropylene, aromatic hydrocarbon resins such as polystyrene, acrylic resins such as polyacrylonitrile and polymethyl methacrylate, vinyl chloride, and vinylidene chloride. halogen-containing resins such as polyethylene terephthalate, polyester resins such as polycarbonate, unsaturated polyester resins,
Preferred are nylon resins and mixtures thereof.

Note that the same material as in 1 is used for the urine collection tool.

The shape of 1 is preferably a cylindrical shape like a test tube, but it may also be a square prism or a polygonal prism. The size can be selected depending on the purpose, but generally 15 to 25Mφ x 100
~140. Things are easy to use.

The urine collection tool is composed of a urine collection tube specimen extraction tool 2 and a urine collection holding section 3.

The specimen retrieval tool 2 is in the shape of a dropper, and has an inflatable part 2 at the top.
-1 and the tubular part 2-2 below which the lower end is open
It is made up of.

The expansion part 2-1 plays the role of a stopper when the specimen extractor 2 is housed in the container 1, and has the same function as a rubber bulb for suction in a normal dropper.

Therefore, when using it, after letting the air in the nucleus escape through the hole 2-2, close the hole with your finger, release the pressure, and aspirate, and a gel-like sample that absorbs urine and swells from the opening at the bottom. It is sucked into the tubular part 2-3 of the dropper and collected.

Next, the collected sample can be efficiently taken out in the required amount without dirtying the hands by strongly pressing and pushing out the expanded portion 2-1 while blocking the hole 2-2 with a finger. Note that the outer diameter of the expanding portion 2-1 in the lateral direction must be larger than the inner diameter of the container 1.

It is preferable that a ring-shaped protrusion 2-4 is provided on the tubular portion 2-3 to ensure a good fit with the urine collection holder 3 and to prevent it from coming off.

Further, the outer diameter of the tubular portion 2-3 is preferably 5 to 10 m.

The urine collection holder 3 is a cylindrical container with a wide mouth and a bottom, and is detachably fitted into the specimen extractor 2.

This urine collection holder 3 has at least one urine collection hole 3-1 in the upper part.

When urine is sprinkled around the hole 3-1, the urine passes through the hole and flows into the urine holding portion 3, where it is absorbed and retained by the superabsorbent compound 4 therein.

It is more efficient to have a large number of holes 3-1, for example 3 to 8 holes. Further, in order to prevent the particles of the superabsorbent compound from spilling out from the holes 3-1, it is desirable to attach an easily removable tape 5, and to peel off the tape 5 at the time of use.

The inner diameter of the urine collection holder 3 is preferably 8 to 18M. The total length of the urine collecting tool fitted into the specimen extracting tool 2 is 2 to 10 mm from the bottom of the storage container 1. Preferably, the length is such that they can separate.

A super absorbent compound 4 is housed in the urine collection holder 3.

The most important point for the urine collection tool of the present invention is the urine collection holder 3.
Powder of super absorbent compound 4 is placed in the bottom of the container. The highly water-absorbent compounds used here are natural and synthetic polymeric compounds. Examples of natural polymeric compounds include alginic acid or its salts, and examples of synthetic polymeric compounds include 7-crylonitrile grafted onto starch. A starch-acrylate graft polymer type super absorbent resin which is polymerized and hydrolyzed with sodium chloride to convert the 10N groups into -CO〇- groups, or cross-linked isobutylene-maleic anhydride based resins. Super absorbent resins such as crosslinked polyacrylate, vinyl alcohol/acrylate copolymer, crosslinked hovar, and acrylic acid polymer are preferably used. Among these, crosslinked polyacrylate-based superabsorbent resins are most preferred.

The particle size of these highly water-absorbent compounds is not particularly limited, but fine particles are easily used.

The amount of the compound particles is proportional to the amount of urine required depending on the purpose of the test, but usually 0.1 g to 10 g is sufficient.

〔Example〕

The present invention will be specifically explained below with reference to Examples.

Example 1 A cross-linked polyacrylic acid sodium superabsorbent resin (Nippon Shokubai Kagaku Kogyo (II)
0.5g of Aqualic ■CA) was stored. When the urine collection tool (2+3> was removed from the storage container 1 and the easily removable tape 5 was peeled off, urine was poured into the vicinity of the backward bending collection hole 3-1.
The urine enters the urine collection holder 3 through the hole 3-1 and immediately flows down.
It was absorbed by the super absorbent resin and swelled to become gelatinous.

This product had no odor and no moisture was observed.

After returning this urine collection tool to the storage container 1 and sealing it with the expansion part 2-1 of the specimen extraction tool 2, carry it to the examination room in a bag and take out the urine collection tool (2+3>. After collecting the necessary amount of urine absorbing gel by suction using the inflatable part 2-1 of the extractor 2, the gel is removed from the urine collection holder 3.Next, the inflatable part 2-1 of the specimen extractor 2 is pressed. Cylindrical part 2-3
Take out the required amount of the specimen collected at the bottom.

When the urine contained in this sample gel was washed out with distilled water and a normal urine test was performed, all test items such as protein, sugar, albumin, and urobilinogen in the urine were collected using the same method as before. It was confirmed that the test results for the same urine showed exactly the same values. Note that, if necessary, the sample may be suspended in distilled water, the polymer removed by filtration or centrifugation, and then tested using a conventional method.

〔Effect of the invention〕

The urinalysis tool of the present invention can solve the problem of bad odor related to urine collection.
Hygiene problems caused by spillage, etc. and the problem of limited locations for urine collection have been solved, and transportation and storage to the testing room and specimen removal have become extremely easy.

Thus, the present invention embodies a rational urine collection, storage, and sample extraction method that is compatible with urine testing and automation of analysis technology, and is expected to help in the early detection of adult diseases and other diseases. .
