Abstract

The invention relates to a nucleic acid safety sampling method derived on the basis of a disposable nucleic acid safety sampler product applied to the patent No. 2022207522657, which belongs to the application in the field of medical detection and solves the problem that the traditional method for sampling nucleic acid is easy to cause cross infection between a sampler and a sampled person when a traditional Chinese medicine nursing staff holds a cotton swab stick to directly sample the naked mouth and nose of the sampled person. The sampling method comprises the steps that an umbrella-shaped transparent opening and closing mask is used, a cotton swab rod is inserted into the central part of the front of the umbrella-shaped transparent opening and closing mask, medical staff holds a push-pull rod connected with the back of the umbrella-shaped transparent opening and closing mask in a hand to send cotton swabs to a sampling area in the mouth of a person to be sampled, the umbrella-shaped transparent opening and closing mask covers the mouth and nose of the person to be sampled, an effective isolation barrier is formed between the medical staff and the mouth and nose of the person to be sampled, the sampling staff performs sampling operation through the umbrella-shaped transparent opening and closing mask, after the operation is completed, the push-pull rod is pulled to fold the umbrella-shaped transparent opening and closing mask inwards to be taken into a rear storage bottle together with the cotton swab rod, a cotton swab head of the mouth is squeezed off through a bottle cap, the storage bottle is in a closed state after the bottle cap is covered, and sampling work is completed.

Description

Safe nucleic acid sampling method

Technical Field

The invention relates to the field of medical detection, in particular to a safety precaution method applied in a nucleic acid sampling process.

Background

The personnel carry out nucleic acid detection, and in the existing method, the medical personnel holds a cotton swab by hand to directly sample the naked mouth and nose of the person to be sampled in the nucleic acid sampling process, so that the gas exhaled by the person to be sampled directly or indirectly contacts the hands and the face of the medical personnel, cross infection is extremely easy to cause to the medical personnel and the person to be sampled, and the existing nucleic acid sampling operation has great potential safety hazard.

Disclosure of Invention

In order to eliminate the cross infection risk of the existing method for collecting nucleic acid samples, the invention provides a safe and environment-friendly method for collecting nucleic acid samples based on a disposable nucleic acid safety sampler product applied in the patent No. 2022207522657, the invention adopts the technical scheme that an umbrella-shaped transparent opening and closing mask is used, a cotton swab rod is inserted in the central part of the front surface of the umbrella-shaped transparent opening and closing mask, the front surface and the rear surface of the mask are totally closed, a sampling medical worker holds a push-pull rod connected with the rear end of the umbrella-shaped transparent opening and closing mask by hands, forwards pushes the cotton swab to a sampling area in the mouth or nose of a sampled person, the mask also covers the mouth and nose of the sampled person, an effective isolation barrier is formed between the mouth and nose of the sampled person and the sampling worker, the medical worker observes the push-pull rod connected with the front cotton swab operation mask through the umbrella-shaped transparent mask, drives the cotton swab to complete the sampling operation and then pulls the push-pull rod backwards to enable the umbrella-shaped transparent opening and closing mask to reduce the outflow of aerosol, and the cotton swab stick is pulled into the rear-end containing bottle together, the broken position of the cotton swab head is just left at the containing bottle mouth, the cotton swab head is broken by the bottle cap at the containing bottle mouth and is sent into the reagent bottle, and the containing bottle mouth with the face mask is tightly covered and sealed to finish sampling work.

Advantageous effects

Compared with the existing nucleic acid collection method, the method disclosed by the invention can achieve the following beneficial effects:

1. the sampling worker is safely prevented from directly facing the naked mouth and nose of the object to be sampled, and meanwhile, the sampling worker does not directly contact the front surface of the equipment in the whole sampling operation process, so that the risk of cross infection is eliminated;

2. the medical waste generated after the environment-friendly sampling operation is finished is completely enclosed in the containing bottle, so that secondary environmental pollution is avoided;

3. the method is the most flexible and convenient operation method in the existing safe nucleic acid collection method, and collection operation is carried out at any time and any place without the limitation of site space.
