Nucleic acid detection equipment capable of continuously working

Abstract

The invention relates to nucleic acid detection equipment capable of continuously working. The nucleic acid detection equipment comprises a nucleic acid amplification reaction module, a fluorescence detection device and a residue removal module, wherein the nucleic acid amplification reaction module comprises a micro-fluidic chip, a to-be-detected sample mixed solution can be injected into a flow channel of the micro-fluidic chip and an amplification reaction chamber, and a nucleic acid amplification reaction is carried out in the amplification reaction chamber; the fluorescence detection device is suitable for detecting a fluorescence signal of the amplification reaction chamber so as to obtain the amount of an amplification product in the amplification reaction chamber in real time according to the fluorescence signal; and the residue removal module comprises a high-temperature fluid cleaning module, and the high-temperature fluid cleaning module is used for injecting fluid with the temperature of 200 DEG C or above into the amplification reaction chamber of the nucleic acid amplification reaction module and the flow channel communicating with the amplification reaction chamber when a detection result of the nucleic acid detection equipment is positive, so that positive residues are removed. According to the nucleic acid detection equipment capable of continuously working, the positive residues in the equipment can be automatically removed, so that false positive of subsequent samples is avoided; and meanwhile, the use cost can be remarkably reduced.

Description

technical field [0001] The invention relates to technical fields such as nucleic acid detection and aerosol detection, and in particular, the invention relates to a continuously working nucleic acid detection device. Background technique [0002] At present, quite a few cases have shown that compared with the SARS epidemic, COVID-19 has a longer incubation period, and people with mild or even asymptomatic infections of COVID-19 may become spreaders of the virus, and fever symptoms of spreaders infected by the virus The relationship to the ability to infect others is neither sufficient nor necessary, exacerbating the difficulty of precisely controlling the spread of the virus. People are eagerly looking forward to a non-contact virus monitoring solution to quickly and accurately identify viruses, provide help for epidemic prevention and control, restore production and living order, and reduce economic and social losses. [0003] Nucleic acid detection is currently the main...
