Problems solved by technology

However, the black mark only has these two pieces of information, and there is a problem that the amount of information is small
In addition, in the method of using a plurality of color marks, if the color mark matching the measurement wavelength of the light source of the device is not selected, the information may not be detected due to the difference in the type of the device and the batch difference of the color marks
Although the barcode has sufficient information, it is necessary to install a barcode reading unit in the analysis device, which will lead to high cost and complexity of the analysis device, etc.

[0088] Figure 5 Another example of the sample analysis tool of the present invention is shown. This figure (A) is a side view, and this figure (B) is a perspective view. As shown in the figure, the sample analysis tool 1 has ten reagent layers 11 and one information recording layer 12 formed on a long substrate 13 . The material of the above-mentioned substrate is not particularly limited, for example, there are resin, metal, glass ion and the like. The color of the substrate is not particularly limited, and may be any of white, gray, black, colored, and transparent. The size of the above-mentioned substrate is not particularly limited, and is appropriately determined according to the test items and the specifications of the analysis device used, for example, the length is 50-150 mm, the width is 2-10 mm, and the thickness is 0.1-1.0 mm. Each reagent layer 11 is formed by affixing a gasket impregnated with a predetermined reagent corresponding to a detection item on the ab...

[0147] Next, according to Figure 8 ~ Figure 14 , an example of continuously changing the shade of a single color in a plurality of regions of the information recording layer will be described. and in Figure 8 ~ Figure 14 in, with Figure 1 to Figure 7 The same symbols are assigned to the same parts.

[0148] exist Figure 8 In the information recording layer 12 shown, as the figure goes from left to right, the achromatic color gradually and continuously changes from black to gray, and gradually and continuously changes from gray to white. In addition, in Figure 9 In the information recording layer 12 shown, as the figure goes from left to right, the achromatic color gradually and continuously changes from white via gray to black (approximately in the center of the figure), and from black to white via gray. In addition, in Figure 10 shown in the information recording layer 12, with Figure 9 In contrast, in one information recording layer 12, as the figure goes from le...

Abstract

A tool for analyzing a specimen having a sufficient volume of information, and being capable of providing the information accurately and reading out that information without requiring any special mechanism. In the tool (1) for analyzing a specimen having a reagent layer (11) and an information recording layer (12) formed on a substrate (13), the information recording layer is divided into one or a plurality of regions and each region is colored with a single color. Information is recorded by at least one of a combination of gray levels of single color in the plurality of regions and the area of each region.

Description

technical field [0001] The present invention relates to a sample analysis tool. Background technique [0002] In clinical testing, a sample analysis tool in which a reagent-impregnated pad is arranged on a plastic substrate is generally used. For example, in urine testing, glucose (GLU), protein (PRO), bilirubin (BIL), urine bilirubin (URO), PH, occult blood (BLD), ketone bodies (KET), nitrite (NIT ), leukocytes (LEU), S.G (specific gravity), color tone, etc., are impregnated in each spacer for each test item, and these spacers are arranged on a plastic substrate. Each of the pads of the sample analysis tool is dipped in urine, and the color change of the above reagent is measured visually or with an optical analysis device, so that the above-mentioned detection items can be detected. In the case of using an optical analysis device, a urine sample is placed in a predetermined test tube, the test tube is placed in the device, and the sample analysis tool is placed in the de...
