Multifunctional nucleic acid testing device

Abstract

The invention discloses a multifunctional nucleic acid detection device, which comprises a base, a transmission mechanism, a liquid suction mechanism, a suction mechanism and a shell sealed with the base. By arranging multiple liquid tanks on the base, multiple functions can be integrated, such as nucleic acid extraction, amplification and detection, or amplification and detection of at least one extracted target template. The multi-functional nucleic acid detection device forms an independent cavity through the base and the shell sealing, and the liquid suction mechanism can be switched between different liquid tanks through the transmission mechanism, liquid suction mechanism and suction mechanism carried by the operating device. And it can realize liquid suction or discharge in different liquid tanks. The multifunctional nucleic acid detection device has a simple structure, can realize small volume, can integrate multiple functions into one body during nucleic acid detection, is easy to operate, and can enable nucleic acid detection to be used in more medical environments that lack professional technicians and experimental conditions. It is beneficial to the application and promotion of nucleic acid detection.

Description

technical field [0001] The invention relates to the field of molecular biology detection, in particular to a multifunctional nucleic acid detection device. Background technique [0002] Nucleic acid amplification detection has been widely used in biomedicine and other fields. In the traditional process of nucleic acid amplification detection, it is common for false positive detection results to be caused by cross-contamination of amplified products. Moreover, most of the templates used in traditional nucleic acid amplification detection methods need to go through an independent sample extraction step, and this step is also likely to cause template cross-contamination and affect the judgment of sample test results. At present, there are some integrated nucleic acid detection devices on the market, such as GeneXpertSystem, etc., which can realize the extraction, amplification and detection of the nucleic acid to be tested in a closed system, which greatly avoids the contamina...
