Abstract
Description
Technical Field
[0001] This invention relates to the field of rapid detection technology. In particular, it relates to a contamination-resistant magnetic detection kit. Background Technology
[0002] Immunochromatography is a simple and rapid diagnostic method, and also an important tool for point-of-care testing (POCT). Originally used for detecting human chorionic gonadotropin (HCG), its simplicity, intuitive results, and lack of complex equipment have led to its widespread application in medical diagnostics, food safety, and environmental monitoring. Immunochromatographic test strips are the core component of this technology, typically consisting of five parts: a sample application area (sample pad), a labeling area (binding pad), a display area (nitrocellulose membrane), an absorbent area (absorbent pad), and a backing plate. The principle is that the added sample flows through the labeling area via capillary action, where the label binds to the target analyte to form a complex. This complex then flows to the display area, where it is captured by antibodies or antigens on the test line, generating a visible signal. The appearance of a control line indicates that the test strip is functioning correctly and the test result is valid. Immunochromatographic test strips are widely used in everyday scenarios such as medical diagnostics and home testing.
[0003] Currently, commercially available test strips typically use interlocking plastic shells with internal interlocking posts connecting the upper and lower shells. However, this design makes assembly and disassembly cumbersome, and the interlocking posts are prone to damage from prolonged friction, resulting in a short lifespan. The interlocking design also hinders the quick opening and closing of the test kit. Furthermore, if the test strip is not used promptly after installation, the sample application area and observation window are exposed to the external environment, making them susceptible to contamination. During the waiting period after sample application, both the sample application area and the detection area of existing test kits are exposed to air, and the added samples are liquids such as blood, saliva, and urine. If the test kit is accidentally spilled, the sample may leak and become contaminated, posing a risk of infection if accidentally touched.
[0004] To address the above issues, this invention provides a contamination-proof magnetic test kit. The flip-top lid prevents contamination caused by tipping or prolonged exposure to air, and also prevents contamination from leakage of the kit contents after use. The lid and body are magnetically connected, allowing frequent users to quickly open and close the lid and bottom, reducing the workload of operators and offering advantages such as convenience and hygiene.

[0014] Preferably, the sample application hole 6 is circular, triangular, square, or elliptical, and the observation window 7 is rectangular, arc-shaped, elliptical, or circular, to facilitate sample application and result observation.
[0015] The beneficial effects of this utility model are as follows: (1) This utility model provides a pollution-proof magnetic detection kit. The lid 1 and the body 2 of the kit are connected by a magnetic design, which has a good tight connection effect, long service life, and is not easy to wear or fail. It is suitable for long-term use in laboratory research and other scenarios that require frequent opening and closing.
