Nucleic acid extraction device

Abstract

The invention relates to the technical field of in-vitro diagnosis, in particular to a nucleic acid extraction device. The nucleic acid extraction device comprises a lysis box; a temperature sensor clamp arranged at a bottom of the lysis box in a sleeving manner, and the lysis box is detachably mounted on a base; a heating sheet mounted in the lysis box and used for heating a lysis solution injected into the lysis box; and a temperature sensing module mounted on the temperature sensor clamp and used for detecting a heating temperature of the lysis box by the heating sheet. According to the invention, the lysis solution is used for lysis and releasing nucleic acid in a sample in a completely closed cavity formed by the lysis box, after being assembled and formed, the device is small in size, relatively simple in structure, convenient to carry and transport, nucleic acid extraction operation steps are simple and convenient, parts in the device can be repeatedly used after being used by replacing other parts, and the device can also be used as an integrated disposable consumable, due to a fact that large positive pressure exists in the lysis box after a sample is lysed, the pressure can be used as a follow-up liquid driving source.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnosis, in particular to a nucleic acid extraction device. Background technique [0002] Nucleic acid detection technology is the general term for a series of technologies that directly detect the nucleic acid of pathogens. It is a detection method with high sensitivity, high specificity and large detection throughput. It is widely used in virus detection, congenital genetic disease diagnosis and paternity test etc. [0003] Nucleic acid detection is generally divided into three steps: nucleic acid extraction, nucleic acid amplification and nucleic acid detection. At present, commercialized nucleic acid detection reagent products, nucleic acid extraction is mostly carried out independently, the equipment is relatively large, there are many parts, the overall structure is complex and heavy, and after the detection is completed, it needs to be taken out separately, which cannot provide convenie...

AI Technical Summary

Problems solved by technology

Currently commercialized nucleic acid detection reagent products, nucleic acid extraction is mostly carried out independently, the equipment is relatively large, there are many parts, the overall structure is complex and heavy, and after the detection is completed, it needs to be taken out separately, which cannot provide convenience for the next operation step. This mode of operation As a result, the entire nucleic acid detection process cannot be carried out smoothly, and there are generally characteristics such as cumbersome operations and low efficiency.
