Anti-propagation nucleic acid detection sampler and sampling method thereof

Abstract

The invention discloses an anti-propagation nucleic acid detection sampler and a sampling method thereof. The anti-propagation nucleic acid detection sampler comprises a supporting base plate and a sampling barrel, a main electric telescopic rod is vertically and fixedly connected over the supporting base plate, and a seat plate is horizontally and fixedly connected to the upper end of the main electric telescopic rod; a gravity sensing switch is embedded in the upper end face of the seat plate, and a disinfection box is fixedly connected to the upper side of the right end of the seat plate. The sampling cotton swab rod penetrates through the sampling cylinder, then the sampling cotton head penetrates into the oral cavity and throat position of a person to be detected, the sampling cotton swab rod drives the sampling cotton head to stir and touch the inner wall of the throat, and after completion, the sampling cylinder is directly pushed to be close to the mouth of the person to be detected, so that the rubber mouth cover is attached to seal the mouth; then the sampling cotton head is drawn into the inner side of the sampling cylinder, virus propagation caused by exposure of the sampling cotton head in an external space after sampling is avoided, and meanwhile, the ejector rod is pressed to enable the cutter sleeve to cut off the sampling cotton swab rod and enable the cutter sleeve to fall into the sample cylinder.

Description

technical field [0001] The invention relates to the technical field of nucleic acid detection samplers, in particular to an anti-spread nucleic acid detection sampler and a sampling method thereof. Background technique [0002] The substance for nucleic acid detection is the nucleic acid of the virus. Nucleic acid detection is to find out whether there is nucleic acid of foreign invading virus in the patient's respiratory specimen, blood or feces to determine whether he is infected by the new coronavirus. Therefore, once the test is "positive" for nucleic acid, it can prove that there is a virus in the patient's body. [0003] The disadvantages of general nucleic acid detection and sampling devices are: when general nucleic acid detection and sampling are performed, a cotton swab is inserted into the nasal cavity or pharyngeal cavity, then the inner wall is wiped, and then the cotton swab is pulled out and put into the corresponding sample bottle. After taking it out from ...

[0003] The disadvantages of general nucleic acid detection and sampling devices are: when general nucleic acid detection and sampling are performed, a cotton swab is inserted into the nasal cavity or pharyngeal cavity, then the inner wall is wiped, and then the cotton swab is pulled out and put into the corresponding sample bottle. After taking it out from the mouth or nasal cavity, the medical staff need to open the sample vial, and then insert the end of the cotton swab. During this process, the cotton swab will be completely exposed to the outside for a period of time. During this process, it is likely that the touch that will affect the detection results will occur, and it will also increase The probability of external transmission is high. At the same time, during the detection process, because the cotton swab is inserted into the nasal cavity or pharyngeal cavity, it will cause discomfort, and the person being tested will naturally react to avoid it. At this time, medical staff need to hold the head from behind
