Description

[Detailed description of the device] [Industrial applications]

The present invention is a urine test container in which a urine test reagent area is formed on the inner surface, and a part of the container is transparent so that the color of the urine test reagent area can be easily and accurately determined. Urine test container.

[Prior art]

For the purpose of detecting urinary sugars, proteins, pH, occult blood, etc., a test reagent area is formed on the inner surface of a bag-shaped container using a gas barrier sheet, and the container itself is sealed for urinalysis. The applicant of the present invention has developed a urine test container in which the volume of the reagent is reduced by extending the use period of the reagent and folding the bag-shaped container during storage before use.
The application has already been filed as an issue. This container tears the hermetically sealed part during use to collect urine in the container, and a urine test is performed by the color reaction of various components in the urine test reagent layer attached to the urine test reagent area by sticking or printing. Is to do.

[Problems to be solved by the device]

When using the urine test container as described above, after the urine collection, the test liquid is discarded, and after a predetermined time, the color change state of the urine test reagent layer provided inside the container is compared with the reference value to make a determination. However, when the urine test reagent layer is provided at a position so as to be sufficiently immersed in the test liquid, it becomes difficult to observe the coloration state of the urine test reagent layer from the outside of the container. Therefore, it is conceivable to form all or part of the urine test container using a transparent material. However, the reagent forming the urine test reagent layer contains a large number of constituent components that are likely to be deteriorated by ultraviolet rays. Has been. For example, glucose oxidase and peroxidase, which are sugar oxidases used in glucose detection ink compositions, guaiac butter, o-tolidine, which is an oxidizable indicator, and L-alcorbyl stearate used as a sensitivity modifier or stabilizer. , Indicators such as methyl red or methyl red sodium salt, bromthymol blue or tetotrabrom phenol blue used in pH measuring ink compositions, other glucose detecting ink compositions, protein detecting ink compositions, pH measuring inks Nonionic surfactants such as sorbitan monolaurate and cationic surfactants such as dodecyltrimethylammonium chloride used for the composition of each reagent layer of the composition and the like are listed as components that are easily deteriorated by ultraviolet rays. To be The deterioration of the reagent due to such ultraviolet rays impairs the coloring ability of the urine test reagent layer. Further, if the transparent material itself is colored by ultraviolet rays, it becomes impossible to accurately determine the coloration state of the reagent layer. The present invention has a storage property of a test reagent that does not adversely affect a reagent layer containing a component that is deteriorated by ultraviolet rays as described above, and a determination that allows the color state of the reagent layer to be visually and easily and accurately observed. An object of the present invention is to obtain a foldable urine test container capable of achieving result confirmation.

[Means for solving problems]

The urine test container of the present invention has a urine test reagent area formed on the inner surface of a collapsible container, and a part or all of the container is made of a transparent and transparent material which is not transparent and is not colored by ultraviolet rays. It was formed. As the UV-blocking material used in the present invention that is colorless and transparent and does not stain with UV rays, a transparent material is coated with a paint containing a UV absorber that does not cause coloring, or the UV absorber is kneaded. Incorporated to produce colorless and transparent films, which are used to form part or all of the container.

[Action]

In the urine test container according to the present invention, part or all of the foldable container is colorless and transparent, and is formed of an ultraviolet blocking material that is not colored by ultraviolet rays, so that the light outside the container is not exposed during use. It penetrates well and brightens the urinalysis reagent area. Therefore, it is possible to accurately and easily judge the color tone of the contents during use. Further, when folded and stored, the ultraviolet ray blocking material blocks ultraviolet rays from the outside of the container to prevent ultraviolet ray deterioration of the constituent components of the reagent layer for urinalysis.
