Dry multipurpose test paper with identification marks

Abstract

This invention relates to a multi-item dry test paper including a base plate with more than two items of test paper blocks on it and identifying strips on zones between the blocks suitable for positioning of test strips or positioning test paper block to be tested by instrument testing. Identifying strips are set at the front of the first or the back of the laser test paper or both as the starting or ending marked strips with advantages of increasing qualified products and productivity and accurate measurement, easy to identify for eye colorimetry test avoiding mistaken match of test blocks related to the standard test blocks.

Description

(1) Technical field: [0001] The invention relates to an in vitro diagnostic test strip, in particular to a dry multiple test strip with identification marks. (two) background technology: [0002] The content of various components in body fluids can be monitored by using dry multiple test strips. For example, urine test strips can monitor pH, bilirubin, urobilinogen, nitrite, protein, glucose, red blood cells, and specific gravity in urine. , Vitamin C, ketone bodies, white blood cells and other items for rapid inspection, for doctors or patients to personally judge health information. The dry test paper sold on the market is generally composed of a substrate and a test paper block fixed on the substrate. The method of use is generally to immerse the test paper strip in the body fluid to be tested for 1 to 2 seconds, and then put the test paper strip When taking it out of the soaked body fluid, suck or scrape off the excess test solution, hold it horizontally, put it into th...

Problems solved by technology

After the fixed-point reading instrument is used for a period of time, due to factors such as the wear and tear of the transmission mechanism of the instrument, or the deviation of the sticking position of the test strip block during the production process of the test strip and the deviation of the position on the instrument, the detector reads There is a deviation between the reading position and the center position of each test paper block. For example, half of the reading position is on the test paper block, and the other half is on the substrate between the test paper blocks, so that the wrong data is read and the measurement result is affected; while the multi-detector fixed detection And the scanning type often produces new errors due to the inconsistency of the detectors. At the same time, the error caused by the deviation of the sticking position of the test strip block and the deviation of the position on the instrument during the production process of the test strip cannot be ruled out, and due to the multi-detector Fixed and scanning detectors are too costly to be preferred by most manufacturers

Therefore, the use of a single-detector scanning detector has the characteristics of low cost and less detection errors caused by machinery, but because the distance between the test paper blocks on the substrate is not large, when the colors of the test paper blocks and the substrate are relatively similar, When the instrument performs scanning measurement, it is sometimes difficult to accurately distinguish each test paper block from the substrate; when visual colorimetry is used to judge, it may be because the color of the test paper block and the substrate is relatively similar, and each test paper block on the substrate The distance between them is not large, and the test paper block may be mismatched with the standard color block on the color guide, resulting in incorrect results

[0004] At the same time, in the production process of test strips, no matter whether it is using automated production equipment or manual pasting, when the long strips of test paper are fixed on the large substrate, there is no position indication or optical auxiliary tracking positioning mark for test strip sticking. , often results in inaccurate pasting positions, which reduces product qualification rate, production efficiency and product quality, and also increases the error of test strip detection
