The medical staff uses the sampling swab for sampling, so that the sampling head of the sampling swab carries the sample, and then the end of the sampling swab with the sampling head is inserted into the sampling tube, and the sampling swab is broken according to the breaking point. Part of the sampling head falls freely into the preservation solution. The sampling swab is placed in the sampling tube at an irregular angle, and then the cap of the sampling tube is tightened to seal and store, so that the sample on the sampling head is fully dissolved in the preservation solution, and finally transported into the laboratory testing process.

In order to improve the testing process, the existing laboratory testing processes mostly use automatic extractors and automatic sample adding devices to extract and add samples. Both the automatic extractor and the automatic sampler are high-precision and high-sensitivity instruments, and the sampling swabs are irregularly placed in the sampling tube. There is no extraction head or sample addition of the subsequent automatic extractor or automatic sampler in the sampling tube.

Therefore, in order to automate the extraction or sample addition, the previous process needs to increase the manpower. The sampling swab is manually taken out of the sampling tube to leave room for operation in the sampling tube. After that, the sampling tube without the sampling swab is used on the machine for automatic extraction. or sample addition. However, in the whole process of virus detection (such as nucleic acid detection of new coronary pneumonia), the operation of manually processing the sampling cotton tip increases the risk of infection, and also increases the cost of labor and protective equipment.
