Hardness-variable protective nucleic acid detector and use method thereof

Abstract

The invention discloses a hardness-variable protective nucleic acid detector and a use method thereof, and belongs to the field of nucleic acid detection. In the process of wiping the throat of a human body to extract secretions, when the human body makes some vomiting actions due to nausea and sensitivity, the oral cavity excessively contacts with and squeezes a double-state sampling rod, an air bag head is subjected to buffer deformation, and thus, on one hand, primary protection on the oral cavity and throat is achieved, on the other hand, along with compression deformation of the air bag head, a rubber sealing ball and a sliding ball gradually move, air in an inflation pipe sleeve and the air bag head is finally released, the inflation pipe sleeve and the air bag head can be shrunk under compression, and the whole double-state sampling rod cannot maintain a linear state due to loss of air support, loses hardness and support force, so that the double-state sampling rod is in a free and soft state, is unlikely to squeeze the oral cavity, and secondary protection for the oral cavity is realized. The detector is of a detachable structure, part of the structure of the detector can be recycled, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the field of nucleic acid detection, more specifically, to a protective nucleic acid detector with changeable hardware and software and a method for using the same. Background technique [0002] In view of the high-risk infection and hidden characteristics of the new coronavirus, the detection of the new coronavirus has become a top priority in countries all over the world. Pharyngeal swabs are used for nucleic acid detection, and there are two methods: oropharyngeal swab sampling and nasopharyngeal swab sampling. At present, it is mostly through the method of taking throat swabs. After the virus infects the oral mucosal epithelium, it will lodge in the oral mucosal epithelium. The purpose of sampling can be achieved by taking throat swabs. Neither surgery nor injection is required, only the subject needs to open his mouth and use a swab like a cotton swab to wipe the secretions near the tonsils and pharyngeal recesses. [00...

Problems solved by technology

[0003] However, in the above-mentioned throat swab collection process, some sensitive people are prone to nausea, vomiting and other gag reflex symptoms during the process of wiping their throats with medical cotton swabs, and, in the process of producing such symptoms, the human body will Reflexively carry out some corresponding vomiting actions, but the medical staff cannot respond, which will easily cause the mouth and throat of the human body to be stabbed by the cotton swab.
