Excreta detection test disc and manufacturing method thereof

Abstract

Disclosed are an excreta detection test disc and a manufacturing method thereof. An excreta detection reagent block and a contrast reagent block are stuck to spoke-arranged fan-blade-shaped substratesof a test disc, so that more detection projects are accommodated. Gaps are formed among substrates, thereby preventing mutual interference to different detection project reagents. Width and shapes ofthe substrates can be changed, so that personalized detection projects and general detection projects are located on the same test disc. Therefore, detection projects with different types are assembled. Each test project is provided with a negative contrast, so that the reliability of a detection result is improved. The detection disc is round and can be rotated in a forward direction or a reverse direction, thereby reducing the detection time.

Description

technical field [0001] The invention relates to medical consumables for in vitro diagnosis, in particular to a test disk for qualitative or quantitative detection of specific components of excreta such as urine and feces. Background technique [0002] Human excreta, especially urine and feces, contain a large amount of physiological and pathological information. Therefore, urine and feces examinations have become routine clinical items. [0003] With the help of dry chemical test strips and supporting scanning testing equipment related to routine urine testing items, routine urine testing has been basically automated; routine automated stool testing has also made significant progress in recent years. [0004] The "all-in-one" detection reagents for urine or feces detection items are assembled on test strips to improve detection efficiency. But there are still shortcomings, including: [0005] (1) The number of testing items increases, the length of test strips increases, t...

AI Technical Summary

Problems solved by technology

[0005] (1) The number of testing items increases, the length of test strips increases, the volume of corresponding testing equipment increases, and the amount of excrement samples required increases;

[0006] (2) Mutual interference between test item reagents affects the accuracy of results;

[0007] (3) Items with obviously different detection principles cannot coexist on the same test strip, for example, heating, cooling, addition of specific reagents, etc. are required;

[0008] (4) The test strip moves back and forth, left and right, which consumes more energy and is less efficient than circular motion;

[0009] (5) Multiple tests share a blank control, which has large errors and is difficult to achieve quantitative detection;
