Problems solved by technology

Automatic control, only need to add samples manually in the whole operation process; however, there are as many as 17 kinds of reagents, and the operation requires suction and rotation, which is cumbersome; moreover, it requires magnetic separation
[0013] It can be seen that in the prior art, most of the research still stays on how to extract nucleic acid; while a small amount of research on the integrated function of nucleic acid extraction and amplification has problems of cumbersome operation and complicated equipment design, which cannot meet the requirements of SARS- The need for CoV2 testing

Abstract

The invention discloses a one-step nucleic acid POCT (point-of-care testing) device, and belongs to the field of molecular diagnosis testing instruments. The one-step nucleic acid POCT device is characterized by comprising a PCR instrument, an extraction tube fixing plate, a piston rod fixing plate and a driving mechanism, wherein extraction tube fixing plate and the piston rod fixing plate are horizontally arranged; the driving mechanism comprises two motors, a coupler, a bearing seat, guide rails, ball screws, screw nuts and a linear bearing, output shafts of the two motors are connected with the coupler, and the coupler is connected with the ball screws; the screw nuts are fixedly arranged on the piston rod fixing plate and the extraction tube fixing plate, and the two screw nuts correspond to the two lead screws respectively. According to the one-step nucleic acid POCT device, a plurality of nucleic acid extraction and amplification test tubes can be operated at the same time, andthe testing efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the field of a medical examination instrument and a molecular diagnosis instrument, and more specifically, relates to a one-step POCT instant nucleic acid detection device. Background technique [0002] Current methods for detecting and diagnosing microbial infections involve the use of quantitative polymerase chain reaction (qPCR) to amplify nucleic acid (RNA / DNA) in patient samples to confirm the presence of pathogens. Additionally, these tests must be done by a testing laboratory where two steps must be performed for diagnosis: nucleic acid extraction followed by qPCR. These two procedures may also be performed by different devices, adding to the complexity and length of time required between sample collection and diagnosis. Finally, these laboratory tests are often done manually, involving physical labor and potentially additional hazards when handling pathogen-positive samples. [0003] Currently, automatic nucle...
