TECHNICAL FIELD
[0001] The utility model relates to PCR pipe technical field, especially a detachable PCR pipe. BACKGROUND
[0002] In the current field of molecular diagnostics and point-of-care testing (POCT), multi-pipes (such as 8-pipes) are widely used in high-throughput testing. Traditional multi-pipes usually exist in a fixed form, i.e., 8 reaction tubes are connected as a whole and cannot be used individually. This design has the following limitations in practical application:
[0003] 1. The traditional multi-pipe requires that the number of samples must be a multiple of 8, otherwise it will cause waste of reagents and consumables. For example, when the number of samples to be detected is less than 8, the entire 8-pipe must still be used, resulting in low resource utilization.
[0004] 2. In the point-of-care testing (POCT) scenario, it is often necessary to quickly detect a single sample, and the traditional multi-pipe cannot meet this demand. The detection personnel must wait for enough samples to be collected before they can perform the detection, which reduces the detection efficiency.
[0005] 3. The traditional multi-pipe usually requires an additional lid, and the reagent needs to be manually added before detection, which increases the operation steps and time cost.
[0006] Therefore, improvements are needed. SUMMARY
