Description

Technical Field

[0001] This utility model relates to the field of antigen reagent kit technology, specifically a sealing structure for an antigen kit. Background Technology

[0002] Antigen kits determine infection by detecting specific proteins (antigens) of pathogens in a sample. Unlike nucleic acid testing, antigen testing does not require amplification of genetic material, so it is faster, but less sensitive.

[0003] Current antigen kits have poor sealing, with neither the sampling port nor the observation port having a sealing structure. This makes the sampling area and reaction area susceptible to contamination, thereby reducing the accuracy of the test. In view of this, we propose a sealing structure for the antigen kit.

[0033] A housing sealing assembly is installed on the inner wall of the second housing 4 and is used to seal the joint between the first housing 1 and the second housing 4. More specifically, the cooperation of the first isolation ring 11 and the second isolation ring 20 isolates the sampling block 15, the marking block 19, the reaction block 16, the second isolation ring 20, and the absorbent filter paper 17 from the other spaces of the second housing 4. The sealing performance is improved by setting the first sealing ring 7 at the joint of the first isolation ring 11 and the second isolation ring 20. Then, by setting the housing sealing assembly at the connection between the first housing 1 and the second housing 4, the internal space of the second housing 4 is further isolated from the external space.

[0034] In this embodiment, a plastic wire 6 is fixedly installed on the outer wall of the sealing plug 3, and the other end of the plastic wire 6 is fixedly connected to the first outer shell 1. More specifically, the plastic wire 6 is used to fix the sealing plug 3.

[0035] In this embodiment, the housing sealing assembly includes:

[0036] A limiting ring 14 is fixedly installed on the inner wall of the second outer shell 4. A second sealing ring 8 is fixedly installed on the top of the limiting ring 14, and the other side of the second sealing ring 8 contacts the first outer shell 1. More specifically...

[0037] In this embodiment, a first mounting groove 9 is provided at the bottom of the first outer shell 1, and a second sealing ring 8 is located in the first mounting groove 9 and is interference-fitted with the first mounting groove 9. More specifically, the interference fit between the second sealing ring 8 on the limiting ring 14 and the first mounting groove 9 improves the sealing performance at the connection between the first outer shell 1 and the second outer shell 4.

[0038] In this embodiment, a plurality of retaining seats 18 are fixedly installed on the bottom inner wall of the second outer shell 4, and are located on the four sides of the second isolation ring 20. A plurality of retaining posts 10 are fixedly installed on the bottom of the first outer shell 1, and the plurality of retaining posts 10 pass through and are press-fitted with the plurality of retaining seats 18.

[0040] In this embodiment, a second mounting groove 12 is provided at the bottom of the first insulating ring 11, and the first sealing ring 7 is located in the second mounting groove 12. Both the first sealing ring 7 and the second sealing ring 8 are made of rubber, and the sealing plug 3 is also made of rubber. The sealing plug 3 is press-fitted with the tapered guide tube 13. More specifically, the press-fit between the sealing plug 3 and the tapered guide tube 13 seals the upper end of the tapered guide tube 13. When testing is required, only the sealing plug 3 needs to be removed.

[0041] In this embodiment, an observation window 5 is provided on the top of the first outer shell 1. The observation window 5 is aligned vertically with the reaction block 16. An acrylic plate 2 is glued to the surface of the first outer shell 1 and completely covers the observation window 5. More specifically, the observation window 5 facilitates the observation of the reaction block 16, and the complete coverage of the observation window 5 by the acrylic plate 2 ensures airtightness without affecting the observation of the reaction block 16.

[0042] In actual operation, when this device is used, the first isolation ring 11 and the second isolation ring 20 cooperate to isolate the sampling block 15, the marking block 19, the reaction block 16, the second isolation ring 20, and the absorbent filter paper 17 from the other spaces of the second outer shell 4. The sealing performance is improved by setting a first sealing ring 7 at the interface between the first isolation ring 11 and the second isolation ring 20. Then, a shell sealing assembly is set at the connection between the first outer shell 1 and the second outer shell 4 to further isolate the internal space of the second outer shell 4 from the external space. The interference fit between the second sealing ring 8 on the limiting ring 14 and the first mounting groove 9 further improves the sealing performance at the connection between the first outer shell 1 and the second outer shell 4. Through this double-layer sealing isolation, the sealing performance is improved. The sealing effect is achieved through the interference fit between the snap-fit ​​post 10 and the card holder 18, which allows the first outer shell 1 and the second outer shell 4 to be installed together. The observation window 5 facilitates the observation of the reaction block 16. The observation window 5 is completely covered by the acrylic plate 2, ensuring the airtightness without affecting the observation of the reaction block 16. The liquid to be tested can be dripped onto the sampling block 15 through the conical guide tube 13. The upper port of the conical guide tube 13 is sealed by the interference fit between the sealing plug 3 and the conical guide tube 13. This completely isolates the sampling block 15, the marking block 19, the reaction block 16, the second isolation ring 20, and the absorbent filter paper 17 from the outside world, preventing contamination. When testing is required, the sealing plug 3 can be removed.
