DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inexpensive and simple method for measuring components in body fluids such as blood and urine, and a test strip for measurement. Toilet paper, tissue paper,
The present invention relates to sanitary tools for measurement such as disposable diapers, excretory bands and incontinence pads.

[0002]

2. Description of the Related Art Conventionally, component analysis of blood, plasma, serum, urine, and other body fluids or secretions has been used for, for example, diagnosis, determination of disease state and therapeutic effect, and therapeutic guidelines.
Test papers are used for simple tests on components of bodily fluids such as urine and blood because they are easy to handle and portable. In the field of clinical testing, test strips are, for example, urine p
H, blood sugar, urine sugar, urine protein, urinary occult blood, urobilinogen,
It is used in tests for bilirubin, ketone bodies, serum cholinesterase, and the like.

[0003]

The inspection using a test strip is
After immersing the test paper in the test liquid, remove it,
The change is performed by measuring the change in color tone due to the color reaction with the naked eye or a device. However, in this test paper, the type of reagent printed, impregnated or applied to the reagent holding part differs depending on the measurement item, and the permeability and water retention of the test liquid to the test paper differ, The amount of the liquid to be inspected is not constant with respect to the amount of the reagent, because the use mode differs depending on the operator.

[0004] For this reason, for example, when the test liquid adheres only in a small amount, the color becomes thinner than it should be, and the amount of the test liquid adhered locally on the test specimen for measurement. If there is a difference, color unevenness occurs in the coloration, making determination difficult.
Furthermore, when a large amount of the test liquid adheres to the test sample, the color on the test sample is diluted by the excessive test liquid and becomes thinner than the actual test solution, thereby causing an erroneous determination. In addition, excess liquid to be inspected is wiped off at the edge of the liquid container to be inspected, or is absorbed by filter paper, etc.
It is difficult to make the amount of the test liquid adhered constant, and the operation is complicated, which is a problem. SUMMARY OF THE INVENTION It is an object of the present invention to solve the problem relating to the amount of liquid to be inspected adhering to a test paper when an inspection is performed using a conventional test paper.

[0005]

According to the present invention, there is provided a test piece for measuring, wherein the amount of the test liquid reacting with the reagent of the test piece can be easily made uniform, the handling is easy, and the color reaction is uniform. The purpose is to provide sanitary tools. That is, in the present invention, the absorbent material piece having a capillary gap or hole is printed with an ink containing a measurement reagent on an inner portion that is not immersed away from the immersion end to form a measurement reagent region. The test piece for measurement, wherein the piece of absorbent material is formed and brought into contact with the textile for sanitary tool, and is supported by the textile for sanitary tool. Is
On the piece of absorbent material having a capillary gap or hole, a boundary line is printed with oil-based ink in the length direction of the piece of absorbent material, and a dipping end is provided on each of both sides of the boundary line. The inside of the part which is not immersed away from the part is printed with ink containing two kinds of measurement reagents to form a measurement reagent area, and the absorbent material piece is brought into contact with the sanitary utensil textile. The test piece for measurement is supported by the textile for sanitary utensils, and the present invention further provides a reagent holding portion having a capillary gap or hole and holding a measurement reagent. And a second absorbent material layer fixed to the first absorbent material layer, the second absorbent material layer being fixed to the first absorbent material layer and having a capillary gap or hole. A piece of material contacts the second absorbent material layer side to the sanitary ware textile. Te, in sanitary tool comprising a component measuring function of the test liquid, characterized in that it is supported on the textile for the sanitary tool.

In the present invention, the test liquid refers to body fluids such as blood and urine of healthy persons and patients, and includes applications to animals. In the present invention, the test piece for measurement is made of an absorbent material, and the absorbent material referred to herein is formed of nonwoven fabric such as paper, fiber, chemical fiber, porous absorbent resin, woven fabric, knitted fabric and paper. However, the material is not particularly limited as long as it has absorptivity. However, the test piece for measurement is preferably made of filter paper. In the present invention, in the test piece, the gap formed between the plurality of fibers and the capillary-shaped hole of the porous body cause a capillary phenomenon, for example, in one area other than the reagent holding portion of the test piece. The test liquid attached to the portion can be moved to the reagent holding portion above, that is, from below to above by capillary action.

In the present invention, the test piece for measurement is formed in a thin film, plate, cylinder, or rod shape. In the present invention, the test piece for measurement can be formed by fixing the first absorbent material layer having the reagent holding portion for measurement to the second absorbent material layer. In this case, the first absorbent material layer and the second
Is formed in a shape corresponding to the shape of the test piece for measurement. The first absorbent material layer and the second absorbent material layer can be bonded and fixed with an adhesive. The adhesive in this case is selected so as not to affect the measurement, and for example, an adhesive based on polyvinyl alcohol can be used.

The first absorbent material layer and the second absorbent material layer can be the same absorbent material layer, but need not necessarily be the same absorbent material layer. However, when the thickness of the absorbent material layer is changed or the properties of the absorbent material are changed, the absorbent material on the side to which the test liquid is attached is more than the absorbent material layer provided with the measurement reagent holding portion. It is preferable that the layer has a larger movement of the test liquid due to the capillary phenomenon.

In the present invention, the measuring reagent printed or coated on the reagent holding portion of the test strip includes, for example, urine pH, blood sugar, urine sugar, urine protein, urinary occult blood, urobilinogen, bilirubin, ketone bodies, serum cholinesterase, and the like. The well-known printing ink for printing test papers containing these measuring reagents is used. In the present invention,
Sanitary utensil textiles are textiles used in toilet paper, tissue paper, disposable diapers, excretory bands and incontinence pads. In the present invention, when a plurality of measurement reagents are provided in one measurement absorbent material piece so that a plurality of measurements can be performed at a time, the plurality of measurement reagent holding units may be inspected. An oily boundary can be formed by printing or coating so that the liquids do not mix with each other.

[0010]

According to the present invention, the test liquid is adhered to a part of the area other than the measurement reagent holding section of the measurement test piece, and the attached test liquid is moved to the measurement reagent holding section of the test piece. Then, a color reaction with the reagent in the measurement reagent holding section is performed,
The test liquid heading toward the measurement reagent holding unit is caused by capillary action, and therefore can be constant regardless of the amount of the test liquid adhering. Therefore, according to the present invention, the test liquid adhering to the measurement test piece is moved by the capillary phenomenon through the absorbent material piece or the second absorbent material layer having no measurement reagent holding portion, and the test liquid is measured. Since the liquid under test comes into contact with the reagent for measurement held in the reagent holding unit, the moving liquid under test becomes saturated due to capillary action, and the amount of the liquid to be tested coming into contact with the reagent for measurement can be made substantially constant. Therefore, the amount of the test liquid that comes into contact with the measurement reagent is constant regardless of the fluctuation factor of the test liquid amount such as a difference in the manner of use by the measurer, and the variation in coloration due to the fluctuation in the test liquid amount. Alternatively, color unevenness can be eliminated, stable measurement can be performed, and handling of the test specimen for measurement can be facilitated.

[0016]

According to the present invention, the test liquid is adhered to a part of the area other than the measurement reagent holding part of the test specimen, and the adhered liquid is attached to the measurement reagent holding part of the test specimen. By moving it, a color reaction with the reagent in the reagent holding part for measurement is performed, so that there is no variation in color and uneven color as compared with the conventional measurement method and the test piece for measurement, and the measurement is stable. And easy handling

Further, according to the present invention, the test liquid adhering to the test piece for measurement moves through the absorbent material piece or the second absorbent material layer having no measuring reagent holding portion by capillary action. Since the portion above the reagent holding portion for measurement that is in contact with the reagent holding portion for measurement is not a colored portion and is not contaminated with the liquid to be tested, the conventional measuring method and test piece can be used. In comparison, even if the test is carried by holding the test piece, it can be detected before the hands become dirty, so that it is very clean. Although the reagent is expensive, in the present invention, only the necessary amount is used because only the colored portion is printed and applied, and the cost can be greatly reduced as compared with the conventional measurement method and test piece.

Since the reagent holding section is not provided in the lower second absorbent material layer, the test liquid is not stained and the correct test can always be performed. After the saturation due to the capillary action, the reagent in the upper first absorbent material layer does not flow to the lower layer. In the case of toilet paper and tissue paper, there is no possibility that a problem will occur if the reagent holding section does not directly contact the skin. In addition, since toilet paper and tissue paper are thin, the reaction value can be sufficiently confirmed. In the case of a disposable diaper, excrement band, or incontinence pad, there is no possibility that a problem occurs if the reagent holding unit does not directly contact the skin. In addition, since the portion directly in contact with the skin is usually in the form of a mesh of rayon-based nonwoven fabric and the base is easy to see, the coloration reaction can be easily confirmed even when printing or coating on a middle layer sheet.
