Description

Throat swab nucleic acid detection sample collection device

Technical Field

The invention belongs to the technical field of nucleic acid sample collection devices, and particularly relates to a throat swab nucleic acid detection sample collection device.

Background

The substance for nucleic acid detection is a nucleic acid of a virus. The nucleic acid detection is to find out whether the respiratory tract specimen, blood or feces of potential virus carriers have the nucleic acid of the virus invaded from the outside to determine whether the virus is infected by the novel coronavirus (2019-nCoV); therefore, once the detection result is positive, the existence of the virus in the potential virus carrier can be proved; after the novel coronavirus infects a human body, the novel coronavirus can propagate in a respiratory tract system, so that whether the human body is infected with the virus can be judged by detecting virus nucleic acid in sputum and a nasopharyngeal swab.

The novel coronavirus has the characteristic of aerosol transmission, has extremely strong transmission capability, a potential virus carrier needs to take off a mask to open a mouth during nucleic acid acquisition, gas exhaled by the potential virus carrier possibly contains a large amount of viruses at the moment, then aerosol is formed to be suspended in air in a detection room, and then the next acquired person possibly inhales the viruses to cause infection during nucleic acid acquisition. However, at present, no pharyngeal swab nucleic acid detection sample collecting device capable of avoiding aerosol transmission hazards exists.

CN213922247U discloses a pharynx swab nucleic acid detects sample collection and strorage device, including gathering the stick, it has the face guard structure of breathing in to cover on the collection stick, the face guard structure of breathing in includes transparent face guard, the through-hole has been seted up at the middle part of transparent face guard, the inside block of through-hole is equipped with the rubber circle, the front end of transparent face guard is fixed with two bridge of the nose backing pieces and two bridge of the nose backing pieces are located the top of rubber circle. The utility model can prevent the potential virus carrier from splashing on the body of the detecting person by the cooperation of the air suction mask structure and the disinfection device, and prevent the virus from forming aerosol to suspend in the detecting room; the attraction of the magnet plate to the iron sheet is utilized to counteract the buoyancy generated by the disinfectant to the sample test tube, so that the sample test tube can be completely immersed into the disinfectant, and the risk of infection of inspection personnel is reduced; through the pedal structure of uncapping that is equipped with, can avoid measurement personnel to contact with the case lid with the hand, reduce cross infection's risk. Obviously, the utility model can not solve the problem of the infection risk brought by other collected persons and medical care personnel in the same area due to aerosol formed by a large amount of viruses in the breath of potential virus carriers.
