Description

Technical Field

[0001] The utility model relates to the technical field of detection reagent cards, in particular to a combined detection reagent card for human immunodeficiency virus. Background Technique

[0002] A detection reagent card is a portable and easy-to-operate detection tool, commonly used for quickly detecting specific components or indicators in various biological samples. The advantages of the detection reagent card include simple operation, fast detection speed, and no need for complex equipment.

[0003] Currently, the existing detection reagent card (such as the patent publication number: CN219915356U) discloses a detection reagent card. The air in the cavity is discharged upward through the exhaust hole, and the liquid sample can flow smoothly from the sample adding window towards the observation window and the exhaust hole. The water climbing effect is ideal, and the liquid sample can fully infiltrate the test strip, improving the sample adding speed, thereby improving the detection efficiency and detection accuracy.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: the test result is detected through a chemical reaction, but only one test strip is installed inside a reagent card, and only the test result can be read. It is easy to cause misjudgment when distinguishing different types of detected viruses. Content of the Utility Model

[0005] (1) Technical problems to be solved: Aiming at the deficiencies of the prior art, the utility model provides a combined detection reagent card for human immunodeficiency virus, which solves the technical problems that the test result is detected through a chemical reaction, but only one test strip is installed inside a reagent card, and only the test result can be read. It is easy to cause misjudgment when distinguishing different types of detected viruses.

[0006] (2) Technical solutions: To achieve the above purposes, the utility model is realized through the following technical solutions:

[0007] The combined detection reagent card for human immunodeficiency virus includes a detection board. Two reaction areas are fixedly installed at the top of the detection board, and two sample adding areas are fixedly installed at the top of the detection board. A blocking membrane is fixedly installed inside each sample adding area. A cylinder is slidably installed at the top of each sample adding area, and a guard plate is fixedly installed at the top of each cylinder.

[0008] Preferably: Two fixing strips are fixedly installed at the top of each sample adding area, and two guiding strips are fixedly installed at the top of each fixing strip. Two push rods are rotatably installed at the bottom of each detection board, a slider is rotatably installed at the end of each push rod, a spring button is slidably installed at the bottom of each slider, a spring rod is installed at the top of each spring button, and two card slots are opened at the top of each fixing strip.

[0009] (3) Beneficial effects: 1. By adding the detection solution from the sample adding area into the interior of the detection plate, coating the HIV antigen on the solid phase carrier, and making it show color on the test paper inside the reaction area, the result is judged by detecting the color development degree. At the same time, multiple test papers are installed inside the detection plate, which is a dual design and can detect specific virus types, increasing the detection accuracy.

[0010] 2. By pressing the protection plate, the protection plate drives the cylinder to slide downward inside the sample adding area. A blocking membrane is installed inside the sample adding area. The blocking membrane is a polymer film, pre-installed inside the sample adding area, which separates the test paper inside the detection plate from the outside of the detection plate.

[0017] In the embodiment of the present application, by providing a combined detection reagent card for human immunodeficiency virus, it effectively solves the problem that the detection result is tested through a chemical reaction, but only one type of test paper is installed inside one reagent card, and only the detection result can be read. It is easy to misjudge when distinguishing different virus types to be detected. By adding the detection solution from the sample adding area into the interior of the detection plate, coating the HIV antigen on the solid phase carrier, and making it show color on the test paper inside the reaction area, the result is judged by detecting the color development degree. At the same time, multiple test papers are installed inside the detection plate, which is a dual design and can detect specific virus types, increasing the detection accuracy. Example

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the test results are detected by chemical reaction test, but a test paper is installed inside a reagent card, which can only read the test results and distinguish different types of detected viruses, which easily leads to misjudgment. The overall idea is as follows:

[0019] In view of the problems existing in the prior art, the utility model provides a human immunodeficiency virus combination detection reagent card, including a detection plate 11, two reaction areas 12 are fixedly installed on the top of the detection plate 11, and color is displayed on the test paper inside the reaction area 12, and the result is judged by detecting the degree of color development. At the same time, multiple test papers are installed inside the detection plate 11. It is a double-link design that can detect specific virus types. Two sample adding areas 15 are fixedly installed on the top of the detection plate 11, and a blocking membrane 16 is fixedly installed inside each sample adding area 15. A cylinder 14 is slidably installed on the top of each sample adding area 15, and a protective plate 13 is fixedly installed on the top of each cylinder 14.

[0020] Two fixing bars 17 are fixedly installed on the top of each sample adding area 15, and two guide bars 22 are fixedly installed on the top of each fixing bar 17. Two push rods 18 are rotatably installed on the bottom of each detection plate 11. A slider 19 is rotatably installed on the end of each push rod 18, and a spring button 21 is slidably installed on the bottom of each slider 19. By pressing the guard plate 13, the guard plate 13 drives the cylinder 14 to slide downward inside the sample adding area 15. A blocking film 16 is installed inside the sample adding area 15. The blocking film 16 is a polymer film pre-installed on the sample adding area 15. Inside the area 15, the test paper inside the detection plate 11 is separated from the outside of the detection plate 11, which plays a certain role in separation. A spring rod is installed at the top of each spring button 21, and two slots are provided at the top of each fixed bar 17. After the slider 19 moves to the two ends of the fixed bar 17, the spring at the top of the spring button 21 generates a downward force on the spring button 21, pushing the spring button 21 to insert into the slot at the top of the fixed bar 17, fixing the position of the slider 19, and at the same time, the two push rods 18 play a role in limiting the movement of the cylinder 14.

[0021] Working principle:

[0022] First step, a test strip is installed inside the detection board 11. Both ends of the test strip are respectively connected to the reaction area 12 and the sample addition area 15. At the same time, multiple indicating scales are installed outside the reaction area 12. By adding the detection solution into the detection board 11 from the sample addition area 15, the HIV antigen is coated on the solid-phase carrier. Then, the serum or plasma to be tested is added. If the sample contains HIV antibodies, they will bind to the solid-phase antigen. Then, the enzyme-labeled anti-human immunoglobulin antibody is added to form an antigen-antibody-enzyme-labeled antibody complex, and it will show color on the test strip inside the reaction area 12. The result is judged by detecting the color development degree. At the same time, multiple test strips are installed inside the detection board 11, which is a dual design and can detect specific virus types.

[0023] Second step, by pressing the protection board 13, the protection board 13 drives the cylinder 14 to slide downward inside the sample addition area 15. A blocking membrane 16 is installed inside the sample addition area 15. The blocking membrane 16 is a polymer film, which is pre-installed inside the sample addition area 15 to separate the test strip inside the detection board 11 from the outside of the detection board 11, playing a certain blocking role. During use, by pressing the protection board 13 to drive the cylinder 14 to squeeze against the surface of the blocking membrane 16. The end of the cylinder 14 is designed in a conical shape. After squeezing the blocking membrane 16, the surface of the blocking membrane 16 is punctured. By pressing the cylinder 14, the cylinder 14 drives two push rods 18 to deflect. The deflection of the push rods 18 generates a thrust on the slider 19, causing the slider 19 to slide on the surface of the fixed strip 17. The slider 19 moves along the guiding strip 22. At the same time, a spring button 21 is installed at the end of the slider 19. After the slider 19 moves to both ends of the fixed strip 17, through the spring at the top of the spring button 21, a downward force is generated on the spring button 21, pushing the spring button 21 to insert into the card slot at the top of the fixed strip 17 to fix the position of the slider 19. At the same time, the two push rods 18 play a role in restricting and positioning the movement of the cylinder 14.

[0024] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
