Virus nucleic acid extraction isolator based on medical detection

Abstract

The invention discloses a virus nucleic acid extraction isolator based on medical detection. The isolator comprises an assembly shell, wherein the section of a main body of the assembly shell is of a rectangular structure, a preset assembly structure is arranged on one side of the assembly shell, a bearing assembly structure is mounted on the inner side of the assembly shell and comprises an adjusting bearing shaft, the adjusting bearing shaft is rotatably mounted on the inner side of the assembly shell, and an adjusting bearing block sleeves the outer side of the adjusting bearing shaft; a driving structure is mounted at the bottom of the adjusting bearing block, guide bearing structures are arranged at two ends of the inner side of the assembly shell, each guide bearing structure comprises a guide carrier column, and an extraction structure is movably arranged on the outer side of each guide bearing column; and each guide bearing column can limit and support the driving structure and the extraction structure during moving, so that the carrying stability of the virus nucleic acid is improved, the virus nucleic acid is prevented from scattering due to acting force such as vibration, and the stable and automatic extraction, cleaning and storage operations are further realized under a closed condition.

Description

technical field [0001] The invention relates to the technical field of extracting devices for medical detection experiments, in particular to an isolator for extracting nucleic acid of viruses based on medical detection. Background technique [0002] Nucleic acid is the general term for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is a biological macromolecular compound polymerized by many nucleotide monomers. It is one of the most basic substances of life. Nucleic acid is a kind of biological polymer. It is an essential component of all known life forms and the most important substance of all biomolecules. It exists widely in all animal and plant cells and microorganisms. Nucleic acid is composed of nucleotides, and nucleotide monomers are composed of five carbons Sugars, phosphate groups and nitrogenous bases. If the five-carbon sugar is ribose, the polymer formed is RNA; if the five-carbon sugar is deoxyribose, the polymer formed is DNA. [0003] After sea...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an isolator for extracting viral nucleic acid based on medical detection, so as to solve the problem that when extracting viral nucleic acid in the above-mentioned background technology, the extraction personnel mainly wear protective clothing to carry out face-to-face extraction, and lack certain isolation protection. measures, the safety protection is poor, which leads to the fact that when the viral nucleic acid is extracted, the viral nucleic acid is easy to spread due to external factors, which easily leads to pollution of the surrounding detection equipment, and the problem of virus infection to the surrounding personnel
