Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a urine test strip suitable for urine tests in mass screening and the like.

[Prior art]

As is well known, a urine test is an examination of physical and chemical properties of urine. Specifically, specific gravity, turbidity,
Examining physical quantities such as color tone and pH, urine glucose, lactose, fructose galactose and other sugars, uric acid, amino acids, proteins, occult blood, urea, bilirubin, alcohol, salts and other chemical components using means such as test paper To do.

The conventional test paper used for such a urine test is formed by cutting each piece into a predetermined strip shape.
At present, it is used for inspection by immersing this one by one in urine.

[Problems of conventional technology]

However, in the conventional urine test strip thus configured, as described above, since it is configured to be cut into individual sheets and used, for example, when conducting a mass examination. Had a problem that its handling was extremely complicated.

The present invention was devised in view of such a current situation, and its purpose is to make it possible to perform a urine test at the time of a mass examination simply and quickly, and to prevent urine from mixing with each other. The purpose is to provide test papers at low prices.

[Structure for solving problems]

In order to achieve the above object, a test sheet for urinalysis according to the present invention comprises a mount having a flat home base and a peripheral edge bent upward, and a plurality of test strips arranged on the surface of the mount. A row, a urine outlet formed in a notch on the mountain top of the mount, and a dam body protruding between the test strip rows, the test strip row being a plurality of different measurement item strips. As a technical premise, a test strip for urinalysis, in which one row is configured for one person, the test strips are arranged side by side along the left-right direction of the mount orthogonal to the central axis passing through the urine outlet. It is characterized in that both end portions of the dam body are bent and formed so as to widen toward the urine discharge direction.

〔Example〕

Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings.

A urine test strip 50 according to this embodiment is shown in FIGS.
As shown in the figure, the mount 51 formed in a home base shape.
And a plurality of test paper pieces 52 arranged on the surface of the mount 51.

The peripheral portion 51a of the mount 51 is, as shown in FIG.
It is configured to be bent upward so that urine does not flow out of the mount 51, and a urine discharge port 53 is cut out at the mountain-shaped top of the peripheral edge 51a.

The test paper strip 52 has seven types of test paper strips 52a impregnated with reagents corresponding to various urine tests and one test blank test strip 52b (rightmost strip in FIG. 1) as one row, and 10 rows are test strips. The urine test for one person is arranged at predetermined intervals along the transport direction x of 50 (the left-right direction of the mount orthogonal to the central axis Y of the mount passing through the urine discharge port 53). As a result, it is configured such that 10 sheets of urine can be simultaneously tested on one sheet of mount 51.

In addition, the test blank test strip 52b is the test strip 5
It is used for discriminating the altered state of No. 2.

When performing a urine test using the urine test strip 50 thus configured, each test strip 5 placed on the mount 51
By allowing urine to flow along the two column directions (the same as the transfer direction x of the test paper 50), it is possible to simultaneously perform a plurality of types of urine tests.

In order to prevent interference (cross contamination) between urines in this case, in this embodiment, a dam body 55 is provided between each row of test strips so that urine of each person is not mixed. Has been done. It should be noted that, as shown in FIG. 1, both end portions of each dam body 55 are formed in an inverted C-shape that widens toward the urine discharge port, and the urine supplied to each test strip row is Make sure that the urine outlet 53 does not enter the other rows.
Is configured to be discharged from.

As a means for measuring the reaction by the urine test strip 50 thus configured, a means by optical measurement is known.

The detector used for the engineering measurement irradiates each test strip 52 with a wavelength appropriately different depending on the measurement target, receives the reflected light from each test strip 52 with a light receiving element, and measures the absorbance thereof. The principle is the same as that of the known optical colorimetric device.

When measuring the turbidity of urine with such a detector, one test strip 52 is used for turbidity comparison, and light of a predetermined wavelength is reflected on the test strip 52 to determine the intensity of the received light. The turbidity can be obtained from the change. In order to avoid the influence of the color of urine, light having a wavelength that is not absorbed by urine may be selected and measured with a filter or the like.

The measurement of the color tone of urine is performed by the test blank test strip 52b, and a light source having a spectroscopic device irradiates and reflects light of a specific wavelength, and the intensity of the light is measured by a light receiver to obtain an absorption coefficient for the specific wavelength. You can ask. Also, if the wavelength of the light from the light source can be continuously changed,
The absorption spectrum of urine can be obtained.

[Effect of device]

As described above, the urine test strip according to the present invention is configured by arranging a plurality of different types of urine test strips in a row, so that a plurality of types of urine test for one person can be supplied once. Because it was configured so that multiple people could work at the same time,
Multiple types of urine tests can be performed simply and quickly with a single operation, and since both ends of the dam body are bent and formed so as to expand toward the urine discharge direction, The urine supplied to each row of test strips is discharged from the urine outlet without entering the other rows, so cross contamination can be reliably prevented, and the configuration is simple and inexpensive. And the like.
