Description

Technical Field

[0001] The utility model relates to an immune detection component and belongs to the technical field of biological detection. Background Art

[0002] Immunochromatography is a simple and rapid diagnostic method and an important tool for point-of-care testing (POCT). It was first used to detect human chorionic gonadotropin (HCG) as a diagnostic tool for early pregnancy. Immunochromatography, primarily performed using immunochromatographic test strips, is simple to use, fast, highly specific, stable, and portable. It has been widely used in clinical diagnosis, food safety, drug testing, and environmental pollution.

[0003] In recent years, immunochromatographic technology has been increasingly used in the field of rapid testing. Combining the advantages of immunology and chromatography, it provides a fast, simple, and highly sensitive method for detecting target substances in various samples. However, most test strips currently available on the market can only detect one or two indicators simultaneously, and cannot simultaneously detect multiple indicators of a sample. During rapid testing, testers need to carry different types of reagent strips for separate testing, resulting in low efficiency. To address this issue, Chinese utility model patent publication number CN213023170U discloses multiple test slots, but these slots are single-use products. This makes them inconvenient for environmental protection and recycling when conducting test strip research and testing, and leads to waste or operational issues. Utility Model Content

[0041] Example 1

[0042] An immunoassay component, such as Figure 1 - Figure 5As shown, it includes an upper casing 1 and a lower casing 2. The upper casing 1 is provided with a sample loading window 11 in the center, through which the sample to be tested can be added; four display windows are provided on the two axes of the upper casing 1, namely a first display window 121, a second display window 122, a third display window 123, and a fourth display window 124, from which the test results can be read respectively.

[0043] Furthermore, a snap hole 13 is provided in the upper clamping shell 1 , and a snap column 23 is provided in the lower clamping shell 2 . The upper clamping shell 1 and the lower clamping shell 2 are snapped together by the snap structure formed by the snap hole 13 and the snap column 23 .

The test strip pads are used to fix the test strip 3.

[0046] Furthermore, the display window is the result display area of ​​the sample to be tested. When the indicator measured in the sample is positive, two clear strips will appear on the corresponding display window; when the indicator measured in the sample is negative, a clear strip will appear on the corresponding display window; if there is no strip, the test result will be invalid.

[0047] Furthermore, after the experiment is over, the card slot pulling handle 25 is pulled, and the card slot 26 is pulled out through the card slot moving track 27; the pulled out card slot 26 can take away the test strip 3 of the experiment and replace the test strip to be used next time; after the test strip is replaced, the card slot is pushed back; the absorption pad replacement port 28 is opened, the absorption pad 24 is replaced, and the absorption pad replacement port 28 is closed; then the next experiment can be carried out.
