Description

Technical Field

[0001] This utility model relates to the field of testing reagents and equipment, and in particular to an immunochromatographic detection kit for the identification of biological products. Background Technology

[0002] Immunochromatographic assay kits are rapid detection technologies based on antigen-antibody specific immune reactions. Using nitrocellulose membranes as solid-phase carriers, samples flow across the membrane strip via capillary action, achieving target analyte capture and color development. Originating in the 1970s, this technology integrates chromatographic separation and immunoassay principles. After decades of development, it has become a core tool for bioproduct identification, widely used in vaccine component analysis, recombinant protein purity detection, and antibody titer determination. Early kits primarily used colloidal gold as the main label, achieving qualitative detection through visible colorimetric reactions. In recent years, novel labeling systems such as fluorescent microspheres and quantum dots have been developed, improving detection performance. However, existing devices also have significant shortcomings. Early immunochromatographic assay kits were integrated disposable items, consisting of test strips and a casing. For example, these integrated disposable items consumed excessive materials, leading to waste. Furthermore, the original equipment was ready to use immediately, with reagents directly installed inside the kit, leaving most of the reagents exposed to air, resulting in poor sealing and easy contamination of the test strips, affecting test results. Therefore, these problems need to be addressed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an immunochromatographic assay kit for the identification of biological products.

[0015] In this utility model, the connecting assembly includes a connecting shaft 11 horizontally installed in the middle of the front end inside the box body 1. A torsion spring 10 is installed on the outside of the connecting shaft 11, which facilitates the installation of the torsion spring 10. One end of the torsion spring 10 is fixedly connected to the connecting shaft 11, which facilitates the provision of elastic force. An L-shaped positioning rod is installed on the other end of the torsion spring 10. A positioning plate is horizontally provided inside the box body 1. A guide rail groove 12 is opened in the middle of the positioning plate, which facilitates the movement and limiting of the torsion spring 10. The groove opened inside the guide rail groove 12 has one end higher than the other. The other end of the L-shaped positioning rod is placed in the groove of the guide rail groove 12. Moving blocks 9 are installed on both sides of the positioning plate, which facilitates the use of the clamping device. An L-shaped clamping plate 8 is movably hinged to the distal ends of the two moving blocks 9, which facilitates the clamping of the placement plate 2. The box body 1 has openings on both sides. A second limiting groove 15 is provided, and a first limiting groove 14 is opened at the front end of the two opposing second limiting grooves 15. The L-shaped clamp 8 can be moved inward through the second limiting groove 15. The L-shaped clamp 8 abuts in the first limiting groove 14, and the L-shaped clamp 8 can be moved outward through the first limiting groove 14. An observation window 4 is installed at the front end of the top of the box body 1, and the detection structure can be observed through the observation window 4. A drip nozzle 3 is installed at the rear end of the top surface of the placement plate 2, and the detection liquid can be dripped through the drip nozzle 3. A placement groove is opened at the rear end of the placement plate 2. An observation groove is opened at the top surface of the placement plate 2, and an L-shaped sealing plate 5 is movably hinged at the rear end of the placement plate 2. A first guide rail 7 is opened on both inner walls of the placement plate 2, and the movement of the limiting block 6 can be facilitated through the first guide rail 7. The two outer ends of the L-shaped sealing plate 5 are fixed with the limiting block 6, and the limiting block 6 can be used to limit the L-shaped sealing plate 5.

[0016] Working principle: When using this invention, specifically the immunochromatographic assay kit for biological product identification, the test strip is first placed in the placement plate 2. Then, the L-shaped sealing plate 5, hinged to the rear end of the placement plate 2, is raised, causing the limiting blocks 6 fixed to both ends of the outer side of the L-shaped sealing plate 5 to move along the first guide rails 7 on the inner walls of both sides of the placement plate 2. When the limiting blocks 6 reach the bottom of the first guide rails 7, they lock, thus stably fixing the test strip onto the placement plate 2. Subsequently, the placement plate 2 is pushed, causing it to move along the box body via sliders installed on both sides. 1. The second guide rails 13 on both sides of the inner wall of the mounting groove move inward. When the placement plate 2 abuts against the moving blocks 9 installed on both sides of the positioning plate inside the box 1, the torsion spring 10 on the outside of the connecting shaft 11 horizontally installed in the middle of the front end inside the box 1 will move along the guide rail groove 12 opened in the middle of the positioning plate. During this process, one side of the L-shaped clamping plate 8, which is movably hinged to the far end of the moving block 9, moves from the first limiting groove 14 opened at the front end opposite to the second limiting groove 15 to the second limiting groove 15, while the other side clamps and fixes the placement plate 2 by hinge rotation. When the placement plate 2 moves to the middle position of the guide rail groove 12, the fixing operation of the placement plate 2 is completed. At this time, the liquid to be tested is dripped into the drip port 3 installed at the rear end of the top surface of the placement plate 2. After waiting for a period of time, the test result can be viewed through the observation window 4 installed at the front end of the top surface of the box body 1. After the test is completed, push the placement plate 2 again. The torsion spring 10 will move along the upper end of the guide rail groove 12 due to its own elasticity, which will drive the placement plate 2 to move outward. At the same time, one side of the L-shaped clamp 8 moves from the second limiting groove 15 back into the first limiting groove 14, and the other side releases its clamping on the placement plate 2. Finally, the placement plate 2 is taken out and replaced as a whole, and the next round of testing can be carried out.
