Problems solved by technology

The rapid nucleic acid extraction device for trace clinical samples of this method can complete all operations as long as the simple "three-step suction" is used for nucleic acid extraction; Finally, it must be dried, which increases the detection time. If alcohol components enter the nucleic acid of the test, it will affect the nucleic acid test and cause false negatives.
In addition, prepackaged nucleic acid extraction reagents are a trend in nucleic acid detection, such as Chinese invention patent applications (CN111286448A, CN111286449A) and the invention patent applied by the applicant (patent name: a nucleic acid rapid extraction four-tube device, extraction device and extraction method , a ...

Abstract

The invention relates to the technical field of nucleic acid extraction, in particular to a rapid nucleic acid extraction device and a method for extracting nucleic acid. The rapid nucleic acid extraction device comprises a rapid nucleic acid extractor, a lysis solution, a washing solution and an eluent, the eluent is used for eluting and collecting nucleic acid substances adsorbed on the rapid nucleic acid extractor, and the washing solution is one or a mixture of more of silicone oil, paraffin oil, C5-C15 alkane oil and halogenated C1-C15 alkane oil. The washing solution does not contain alcohol, does not need to be aired, does not influence nucleic acid, and ensures quick and effective detection.

Description

technical field [0001] The present application relates to the technical field of nucleic acid extraction, in particular to a rapid nucleic acid extraction device and a method for extracting nucleic acid. Background technique [0002] Medical testing of in vitro samples has the advantages of simplification, automation, and proximity to patient sites, and plays an important role in clinical medicine and related medical research fields. At present, the automation of sample processing and testing is low, which cannot meet the needs of rapid, timely and high-throughput testing of samples in clinical practice. Nucleic acid molecular detection technology has strong advantages in laboratory medicine and clinical research. The column method and magnetic bead method are commonly used for nucleic acid extraction, but there are common problems such as complicated operation, laborious and high cost. [0003] Chinese invention patent application (publication number: CN101684463, publicat...
