Nucleic acid safe sampling method

Abstract

The invention discloses a nucleic acid safe sampling method which is derived on the basis of a disposable nucleic acid safe sampler product applied in the patent number 2022207522657, and belongs to application in the field of medical detection. The risk that in existing nucleic acid sampling, a medical worker directly samples the exposed mouth and nose of a sampled person by holding a cotton swab stick with a hand, and cross infection is easily caused between the sampling worker and the sampled person is solved. According to the method, an umbrella-shaped transparent opening and closing mask is used, a cotton swab rod is inserted in the center of the front face of the umbrella-shaped transparent opening and closing mask, a medical worker holds a push-pull rod connected to the rear side of the umbrella-shaped transparent opening and closing mask to forward feed cotton swabs to a sampling area in the mouth of a sampled person, and then the umbrella-shaped transparent opening and closing mask covers the mouth and nose of the sampled person. An effective isolation barrier is formed between the mouth and nose of a medical worker and the mouth and nose of a sampled person, the sampling worker carries out sampling operation through the umbrella-shaped transparent opening and closing mask, the push-pull rod is pulled to fold the umbrella-shaped transparent opening and closing mask towards the inner side after the operation is completed, the umbrella-shaped transparent opening and closing mask and a cotton swab are collected into a rear storage bottle together, and a cotton swab head at a bottle opening is squeezed off by a bottle cap. After the bottle cap is covered, the storage bottle forms a closed state, and the sampling work is completed.

Description

technical field [0001] The invention relates to the field of medical detection, in particular to a safety precaution method applied in the nucleic acid sampling process. Background technique [0002] Personnel conduct nucleic acid testing. During the nucleic acid sampling process, in the existing method, medical staff directly sample the exposed mouth and nose of the sampled person with a cotton swab, so that the breath exhaled by the sampled person directly or indirectly contacts the hands and face of the medical staff, and the sampling Both medical staff and sampled persons are prone to cross-infection, which makes the current nucleic acid sampling operation a great safety hazard. SUMMARY OF THE INVENTION [0003] In order to eliminate the risk of cross-infection in the currently used method for collecting nucleic acid samples, the present invention provides a safe and environmentally friendly method for collecting nucleic acid samples based on the disposable nucleic aci...

[0002] Nucleic acid detection by personnel. In the nucleic acid sampling process, the existing method is to directly sample the exposed mouth and nose of the sampled person by the medical staff holding a cotton swab, so that the exhaled gas of the sampled person directly or indirectly contacts the hands and face of the medical staff, and the sampling Medical staff and sampled persons are extremely prone to cross-infection, which makes the current nucleic acid sampling operation a great safety hazard
