Background
The identification of respiratory infectious diseases requires nucleic acid detection, which is roughly divided into two steps: 1) collecting a patient sample; 2) and detecting the center. The sample collection work of the first step has higher requirement on the collected position, and the sample must reach the pharyngeal posterior wall or tonsil part, otherwise, the detection accuracy is influenced. A doctor will typically prepare a reagent stick (pharyngeal swab) similar to a long cotton swab and a reagent tube. The patient should take off the mask and then open his mouth to make an "o" sound, so that the posterior pharyngeal wall is exposed. At this time, the doctor extended the reagent stick to the posterior pharyngeal wall of the patient and smeared to take a sample. And finally, placing the sample into a reagent tube for sealing to finish sampling.
During the sampling process, the patient inevitably feels uncomfortable. Patients sometimes suffer nausea, choking, and coughing. There is a lot of gas from the patient's mouth carrying the virus out and even a relatively large amount of splashed liquid. The virus directly flies out, greatly increasing the risks faced by medical staff and even leading some medical staff to be cross-infected. In addition, in the process of manual sampling, due to factors such as differences of water products operated by different medical workers, non-standardization in the acquisition process and the like, the quality of swabs is different, false negatives are easy to occur, and the judgment of the state of an illness is influenced.
