Antigens are substances that can cause immune responses. Accurate detection of antigens is of key significance for the diagnosis, monitoring and treatment of diseases.

[0003] The antigen test kit usually contains an antibody that can specifically recognize the target antigen. When the collected sample (such as nasopharyngeal swab, oropharyngeal swab, blood, etc.) is added to the sample well of the test kit, if the target antigen exists in the sample, the antigen will combine with the antibody in the test kit. By observing whether the detection area is colored and the color development situation, it can be determined whether the target antigen exists in the sample and the approximate range of the antigen content.

[0004] In the prior art, the sample holes and observation detection areas of some antigen test kits are not sealed, and the entire area is exposed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Since it is a prior art, it will not be described in detail in this case. A detection area 4 is set on the upper surface of the reagent box body 1, and a sample hole 5 is set on the upper surface of the reagent box body 1 adjacent to the left side of the detection area 4. A threaded hole 6 is opened on the upper surface of the reagent box body 1 adjacent to the left side of the sample hole 5. A sealing component 2 is set on the upper surface of the reagent box body 1, and a fixing component 3 is set on the upper surface of the reagent box body 1 adjacent to the left side of the sealing component 2. The sealing component 2 includes a protective plate 21, the protective plate 21 is fixedly connected to the upper surface of the reagent box body 1, and a transparent plate 22 is fixed on the inner wall of the protective plate 21. The transparent plate 22 is made of transparent material to ensure that the user can clearly observe the situation inside the detection area 4, thereby improving practicality. A fixing block 23 is fixedly connected to the left surface of the protective plate 21, and a through groove 210 is opened on the inner wall of the fixing block 23.

[0031] Reference Figure 1 - Figure 2 The fixing assembly 3 includes a rectangular plate 31, which is slidably connected to the left side of the fixing block 1 23 on the upper surface of the reagent box body 1. The left surface of the rectangular plate 31 is fixedly connected to a fixing block 22, and a bolt 33 is threadedly connected to the upper surface of the fixing block 22. The bolt 33 is a prior art, which is a rod-shaped structure with a threaded outer wall. At the same time, the thread set on its outer wall is adapted to the thread of the inner wall of the threaded hole 6 to ensure the stability of the connection. The top of the bolt 33 is threadedly connected to the inner wall of the threaded hole 6. The top of the right surface of the rectangular plate 31 is fixedly connected to the limiting plate 34. The limiting plate 34 is inserted into the inner wall of the through groove three 35, and then the fixing block two 32 is fixed by the bolt 33. In this way, the push plate 28 can be stuck and fixed to ensure the stability of the connection between the sealing plate 1 24 and the sealing plate two 25. The left surface of the top of the push plate 28 is provided with a through groove three 35, and the right end of the limiting plate 34 contacts the inner wall of the through groove three 35.

[0032] Reference Figure 2 - Figure 3The inner wall of the fixed block 23 is elastically connected with the sealing plate 24 through a spring 212. The spring 212 itself has a certain elasticity. It always pushes the sealing plate 24 to move backward through its own elasticity to ensure the stability of the connection between the sealing plate 24 and the sealing plate 25. The sealing plate 24 is slidably connected to the inner wall on the front side of the fixed block 23. One end of the spring 212 is fixedly connected to the inner wall on the front side of the fixed block 23. The other end of the spring 212 is fixedly connected to the front surface of the sealing plate 24. The inner wall at the rear end of the fixed block 23 is slidably connected with the sealing plate 25. A sealing groove 26 is provided on the front surface of the sealing plate 25. A sealing strip 27 is fixedly connected to the rear surface of the sealing plate 24. The sealing strip 27 is adapted to the sealing groove 26 to ensure sealing. The sealing strip 27 contacts the inner wall of the sealing groove 26.

[0033] Reference Figure 2 - Figure 3 The left surface of the sealing plate 24 is fixedly connected with a sliding rod 211, and the sliding rod 211 is slidably connected to the inner wall of the through groove 210. The upper surface of the left end of the fixed block 23 is penetrated and slidably connected with a push plate 28. A through groove 29 is provided on the left surface of the push plate 28. The through groove 29 has a certain slope to ensure that when the push plate 28 moves, the sliding rod 211 can move along the slope of the through groove 29, thereby improving practicality. The outer wall of the left end of the sliding rod 211 is slidably connected to the inner wall of the through groove 29. Multiple groups of springs 212 are provided, and one end of the multiple groups of springs 212 is fixedly connected to the inner wall of the rear end of the fixed block 23, and the other end of the multiple groups of springs 212 is fixedly connected to the rear surface of the sealing plate 25. By setting up multiple groups of springs 212, the stability and sealing between the sealing plate 24 and the sealing plate 25 when closed can be ensured.

[0034] Working principle: When using the reagent kit body 1, it is necessary to drop the collected sample into the interior of the sample hole 5, and then the result of the sample detection can be observed through the detection area 4. In the process of dropping the sample into the sample hole 5, it is necessary to ensure that the limit plate 34 and the through groove three 35 are separated. At this time, press the push plate 28, and the slide bar 211 will slide on the inner wall of the through groove two 210 along the slope of the through groove one 29, and the sealing plate one 24 will move accordingly. At the same time, the sealing plate one 24 will drive the sealing strip 27 to move and separate from the inner wall of the sealing groove 26, and the sealing plate one 24 will also squeeze the spring 212. In this process, the movement mode of the sealing plate two 25 is the same as that of the sealing plate one 24, but in the opposite direction, so that the sealing plate one 24 and the sealing plate two 25 can be opened, and the user can drop the sample into the interior of the sample hole 5. After the dropping is completed, loosen the push plate 28. At this time, multiple groups of springs 212 will respectively push the sealing plate one 24 and the sealing plate two 25 to move in the opposite direction for reset. The subsequent structural matching method is the same as above, but the matching direction of some structures is opposite.

[0035] When the reagent kit body 1 is used up, the rectangular plate 31 can be pushed to move until the rectangular plate 31 drives the limiting plate 34 to be completely inserted into the inner wall of the through slot three 35. At this time, the bolt 33 will overlap with the threaded hole 6. Then, the bolt 33 is rotated, and the bolt 33 will enter the inner wall of the threaded hole 6 to limit the rectangular plate 31. In this way, the push plate 28 will be stuck, and the sealing plate 1 24 and the sealing plate 2 25 will not be easily opened, thereby ensuring the sealing effect and improving practicality.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
