Description

Technical Field

[0001] The utility model relates to the technical field of antibody detection, and particularly relates to an antibody immunochromatographic detection device. Background Technique

[0002] The principle of immunochromatography is to first fix specific antibodies on a certain zone of a nitrocellulose membrane. When one end of the dry nitrocellulose is immersed in a sample (urine or serum), due to capillary action, the sample will move forward along the membrane. When it moves to the area where the antibodies are fixed, the corresponding antigen in the sample will specifically bind to the antibodies. If immunogold or immunoenzyme staining is used, a certain color can be shown in this area to provide qualitative or semi-quantitative detection data for the sample, thus realizing specific immunodiagnosis.

[0003] When the existing antibody immunochromatographic detection device detects serum, it is necessary to prick the finger with a needle and then drop the blood on the test strip. However, during actual detection, there may be a lot of dust and bacteria at the finger blood collection site. Unprofessional testers often cannot effectively clean the dust and bacteria at the finger. These dust and bacteria may directly flow into the detection device along with the blood, thus affecting the antibody immunochromatographic detection result. For this reason, we propose an antibody immunochromatographic detection device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an antibody immunochromatographic detection device. A finger cleaning mechanism is arranged at the lower shell of the existing antibody immunochromatographic detection kit. The finger cleaning mechanism forms a structure at the lower shell that can standardize the cleaning of the blood collection finger. When an unprofessional tester uses the antibody immunochromatographic detection kit, the finger can be rotated circumferentially at the primary cleaning cylinder and the secondary cleaning cylinder of the finger cleaning mechanism, so as to clean and disinfect the finger twice using alcohol cotton rings, ensuring that the antibody immunochromatographic detection kit can collect blood at a clean finger, avoiding the stains at the finger from affecting the detection effect of the antibody immunochromatographic detection kit, and effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An antibody immunochromatographic detection device, comprising an upper shell, a test strip, and a lower shell. The test strip is press-fitted between the upper shell and the lower shell. The device further includes a finger cleaning mechanism, which includes an outer connecting plate A, an outer connecting plate B, a primary cleaning cylinder, a secondary cleaning cylinder, an inner connecting plate, an alcohol cotton circle, a bottom sealing box, and a plugging package. The outer connecting plate A and the outer connecting plate B are symmetrically fixed to the bottom shell surface of the lower shell. The primary cleaning cylinder and the secondary cleaning cylinder are respectively inserted through the middle plate holes of the outer connecting plate A and the outer connecting plate B.

The alcohol cotton circle is filled in the barrel mouths of the primary cleaning cylinder and the secondary cleaning cylinder. A bottom sealing box covering the outer connecting plate A and the outer connecting plate B is sleeved outside the lower shell. Plugging packages for embedding the primary cleaning cylinder and the secondary cleaning cylinder are symmetrically protruded on the inner box walls on both sides of the bottom sealing box.

[0007] Further, a concave surrounding groove for clamping an inner surrounding rubber strip is recessed on the outer shell wall of the lower shell, and the inner surrounding rubber strip is fixed on the inner wall of the box mouth of the bottom sealing box;

[0008] By adopting the above technical solution, the lower shell is clamped and sealed by the concave surrounding groove in cooperation with the inner surrounding rubber strip in the bottom sealing box.

[0010] By adopting the above technical solution, the package body of the plugging package can be adaptively clamped into the barrel mouths of the primary cleaning cylinder and the secondary cleaning cylinder for plugging and sealing.

[0011] Further, the connection between the plate hole of the outer connecting plate A and the cylinder body of the primary cleaning cylinder is adhesively fixed;

[0012] By adopting the above technical solution, the outer connecting plate A is adhesively fixed to the cylinder body of the primary cleaning cylinder, making the primary cleaning cylinder not easily fall off.

[0013] Further, the connection between the plate hole of the outer connecting plate B and the cylinder body of the secondary cleaning cylinder is adhesively fixed;

[0014] By adopting the above technical solution, the outer connecting plate B is adhesively fixed to the cylinder body of the secondary cleaning cylinder, making the secondary cleaning cylinder not easily fall off.

[0016] By adopting the above technical solution, the primary cleaning cylinder and the secondary cleaning cylinder are filled with a circle formed by winding the alcohol cotton circle, facilitating the finger to extend into the primary cleaning cylinder and the secondary cleaning cylinder for rotational cleaning.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model sets a finger cleaning mechanism at the lower shell of the existing antibody immunochromatographic detection kit. The finger cleaning mechanism forms a structure that can standardize the cleaning of the blood-taking finger at the lower shell.
