PH Sectional sequencing 13 item urine test paper

Abstract

A thirteen-item urine test paper with the pH value arranging in subsection relates to substrate and test paper mass fixed on it. From the top of the urine test paper to the handle ending, the arrangement sequence is white blood cell, acetone body, nitrite, urobilinogen, bilirubin, protein, dextrose, urine proportion, pH, occult blood, blank, uric creatinine, oxalate in urine, urinary albumin. It can avoid the disturb causing for great diversity of the pH value between each test paper mass by arranging in subsection according to different pH value. It reduces the disturb to the least causing for the flow and diffuse of the need test liquid, and prevents some test paper mass with high or low pH value changing for exposure in the air too much time. Its substrate length and effective test length are corresponding to the existing urine test paper and it matches to the existing test appearance.

Description

(1) Technical field: [0001] The invention relates to an in vitro diagnostic test paper, in particular to a thirteen-item urine test paper for pH segmental sorting. (two) background technology: [0002] Using dry multiple urine test strips can quickly test the pH, bilirubin, urobilinogen, nitrite, protein, glucose, red blood cells, specific gravity, vitamin C, ketone bodies, white blood cells and other items in the urine. Doctors or patients personally judge health information. The dry urine test strips currently on the market generally consist of a substrate, double-sided adhesive for pasting, and one end embedded and fixed on the substrate. pH, blank blocks and other items such as bile It is composed of test paper blocks of erythrin, urobilinogen, red blood cells, protein, nitrite, vitamin C, glucose, white blood cells, specific gravity, ketone bodies, etc. The method of use is generally to immerse the test paper strips in the body fluid to be tested 1 ~ 2 seconds, when ta...

Problems solved by technology

However, when the test strip is taken out from the soaked body fluid during operation, no matter how careful the operation is, it is difficult to prevent the excess test solution from flowing and spreading between the test strips, resulting in interference phenomena such as color crossing and fading, or it is difficult to directly remove the test strip from the body fluid. Inhibition of chemical reaction interference phenomena such as cross-color, fading and other obvious color change resolution

Although it is required in the instruction manual that the excess test solution should be sucked off or scraped off when the test strip is taken out of the soaked body fluid, and held horizontally, it is difficult to ensure timely and thorough removal of the test strip during clinical testing. Absorb or scrape off excess test solution

The anti-interference measures currently used include the following methods: coating a special hydrophobic coating on the substrate, so that the excess test solution should not be accumulated. The disadvantage of this scheme is that it requires additional coating processing, and excessive hydrophobicity It will reduce the sticking performance of the double-sided tape, so the effect is not ideal

The second is to cover the entire test strip with a layer of hydrophobic nylon mesh, and separate and fix each piece of test paper. This method requires special equipment and special materials, and the surface is covered with a layer of hydrophobic nylon mesh. Will affect the visual judgment of color

However, when in use, some test strips are exposed to the air for a long time, which is easy to absorb moisture and undergo chemical changes; in addition, the flow of the body fluid to be tested from the handle end of the test strip will still affect some test strips other than the pH value
