Rapid home detection device for novel coronavirus

Abstract

The invention relates to the technical field of virus detection, in particular to a rapid home detection device for novel coronavirus, which comprises a device body and a display screen installed at the front end of the device body, a connecting shell is fixedly installed on one side of the device body, and a recognition mechanism is arranged on the inner wall of the connecting shell; the recognition mechanism comprises a bracket fixedly installed on the inner wall of the connecting shell and a biological chip movably inserted from the rear end face of the connecting shell and located on the upper end face of the bracket, a camera mechanism capable of being adjusted in a lifting mode is arranged on the top face of the inner side of the connecting shell, and an ultraviolet mechanism capable of being adjusted front and back is arranged on inner wall of connecting shell close to upper part of identification mechanism. According to the invention, the rapid detection device can be well applied to combination of a CRISPR technology and an isothermal amplification technology, efficient recognition of nucleic acid sequences, rapid conversion of signals and high-fidelity amplification can be realized, meanwhile, the dependence on instrument equipment, a detection environment and personnel operation is greatly reduced, so that the aim of quickly, efficiently and sensitively detecting viruses is achieved.

Description

technical field [0001] The invention relates to the technical field of virus detection, in particular to a home rapid detection device for novel coronavirus. Background technique [0002] CRISPR is a repetitive sequence in the genome of prokaryotic organisms. It is an immune weapon produced by the struggle between bacteria and viruses in the history of life evolution. Simply put, viruses can integrate their genes into bacteria and use bacterial cell tools to replicate their genes. Service, bacteria have evolved the CRISPR-Cas9 system in order to remove the foreign invading genes of the virus. Using this system, bacteria can quietly remove the virus gene from their own genome. This is the unique immune system of bacteria, and it is an archaea An acquired immune system that resists the invasion of foreign genetic materials such as viruses and bacteria; [0003] Constant temperature amplification technology is a new nucleic acid detection technology that combines a new generat...

Problems solved by technology

[0004] At present, the diagnosis of novel coronavirus pneumonia mainly uses nucleic acid detection based on fluorescent quantitative PCR, which requires a specialized molecular laboratory, which requires high requirements for instruments and operators, and the overall detection time is long, the accuracy is insufficient, and the false negative rate Therefore, a portable nucleic acid detection device with high sensitivity, easy operation, and short detection time is needed for application scenarios where personnel are scattered and laboratory infrastructure is lacking, which can effectively improve the efficiency of epidemic prevention and control
