Problems solved by technology

[0003]Currently, the chemical chromogenic method used in fecal occult blood detection requires the use of at least one Other detection reagents, such as buffer solution (diluted feces) or display solution (containing peroxide) or chromogenic solution (containing chromogenic reagent), can be used to complete the detection. Potential problems with polluting the environment

Embodiment Construction

[0017] Such as figure 1 As shown, the fecal occult blood detection test paper according to this embodiment includes a square test paper body 1, a cross-shaped color-developing layer 2 formed in the middle of the test paper body 1 (the color-developing layer is composed of tetramethylbenzidine and peroxide , can be formed on the test paper body by coating or printing, etc.) and the latex 3 used to seal the periphery of the color-developing layer 2 .

[0018] The fecal occult blood detection test paper in this example is best stored in an airtight, room temperature, and humidity

[0019] The fecal occult blood detection test paper can be detected by the patient himself. Specifically, after defecating, throw the detection test paper into the urinal, and observe whether there is a color reaction in the cross area to know whether he has fecal occult blood. As long as there is an obvious color change at any position in the cross area, it means that the stool contains occult...

Abstract

The invention relates to feces occult blood test paper and a preparation method thereof. The feces occult blood test paper comprises a test paper body and is characterized by further comprising a color developing layer and latex, wherein the color developing layer is formed on the test paper body and can have color change in the presence of hemoglobin, the latex is arranged on the test paper body and used for sealing the periphery of the color developing layer. The feces occult blood test paper is adopted for testing without professional testing people, and is very simple to operate, sanitary and environmentally-friendly; and the result can be fast obtained.

Description

technical field [0001] The invention relates to a detection test paper and a preparation method thereof, in particular to a detection test paper for fecal occult blood. Background technique [0002] The earliest detection method of fecal occult blood was chemical colorimetric method. In 1864, Van Deen first used guaiac gum as an indicator to detect fecal occult blood. Afterwards, chemical colorimetric methods such as benzidine method, reduced phenolphthalein method, o-benzidine method, piramicave method, colorless malachite green method, and tetramethylbenzidine method were proposed to detect fecal occult blood. The basic principle of the method is the same. Fecal occult blood contains hemoglobin produced after blood cells are digested. Hemoglobin has a porphyrin structure and has a similar activity to peroxidase. In the presence of hemoglobin, peroxide will be catalyzed to produce nascent oxygen. Nascent oxygen is very active and has a very strong oxidation ability. Holes...
