Description

Technical Field

[0001] The utility model relates to the technical field of medical testing instruments, in particular to a fluorescent immunochromatography detection kit. Background Art

[0002] Immunochromatographic Assay (ICA) is an analytical method developed at the end of the 20th century that combines immunoassay and chromatographic techniques. This method has the characteristics of specificity, simple operation, and rapidity, and is widely used in important fields such as clinical diagnosis, environmental monitoring, and food safety. Traditional immunochromatographic technology uses colloidal gold as a marker to qualitatively detect or semi-quantitatively analyze the target through strip color development. Although this method is simple and rapid, it has poor sensitivity and is difficult to accurately quantify. As a new type of immunoassay technology, fluorescent immunochromatography technology not only retains the advantages of rapid on-site detection of traditional colloidal gold test strips, but also adds the high sensitivity of fluorescent detection technology, becoming one of the main ways to improve the detection performance of immunochromatographic methods.

[0003] A Chinese patent with authorization announcement number CN217416674U discloses a fluorescent quantitative detection immunochromatography kit, which relates to the technical field of medical testing instruments.

A sealing cover plate that slides along the limited sliding groove with a single degree of freedom is installed on the top of the kit body, a first clamping mechanism for fixing the sealing cover plate is installed at one end of the top of the kit body, a detection card is movably installed inside the placement groove, a second clamping mechanism for fixing the detection card is installed at one end of the placement groove, a detection test paper is installed in the middle of the top of the detection card, and a dropper for sample dripping is provided on one side of the top of the detection card.

[0004] The above-mentioned patents still have the following technical defects: 1. When conducting a test, it is necessary to release the limit of the test card, take out the test card and place it in the test slot for testing, and after the test, the test card needs to be taken out of the test slot, which is a cumbersome operation; 2. The number of test cards stored in the test kit is limited, and the storage space cannot be maximized. 3. The test card is exposed and easily contaminated by moisture, which can easily affect the accuracy of the test data. Utility Model Content
