Problems solved by technology

[0002] The substance of nucleic acid detection is the nucleic acid of the virus; nucleic acid detection is to find out whether there is nucleic acid of foreign invading virus in the patient's respiratory specimens, blood or feces, to determine whether he is infected by the new coronavirus; therefore, once the nucleic acid is "positive", you can To prove that there is a virus in the patient's body. In the prior art, most nucleic acid detection methods are to detect the virus nucleic acid in the sputum and nasopharyngeal swabs of the tester's mouth to determine whether the human body is infected with the virus, and then mark the collected samples and send them to the hospital. The efficiency is low, and the possibility of cross-infection is prone to occur, which affects the accuracy of nucleic acid detection. Therefore, a nucleic acid detection and extraction device and extraction method are designed here to solve the above problems.

Embodiment 1

[0025] see Figure 1-4 , this embodiment provides a nucleic acid detection and extraction device and extraction method, including a sampling tube 1 and a sampling mechanism 2, one end of the sampling tube 1 is provided with a storage cavity 14, and the end of the sampling tube 1 away from the storage cavity 14 is provided with a screw thread Storage groove 16, a guide hole 15 for communicating with the storage cavity 14 and the threaded storage groove 16 is provided between the storage cavity 14 and the threaded storage groove 16, and the sampling mechanism 2 includes a second magnet disc 23 and a guide rod 21, the second The magnet disk 23 is slidably arranged inside the storage cavity 14, one end of the guide rod 21 is fixedly inserted into the axial side wall of the second magnet disk 23, and the other end of the guide rod 21 slides through the guide hole 15 and extends to the threaded storage groove 16 Inside, the other end of the guide rod 21 is fixedly sleeved with a ste...

Embodiment 2

[0033] see figure 1 , further improvements have been made on the basis of Example 1:

[0034] In order to solve the problem of how to identify the identity of the detected person conveniently, the outer wall of the sampling tube 1 is provided with a label strip 11, and the surface of the label strip 11 is covered with a dust-proof film 12 that can be torn at will. , it is convenient to put a marker pen on the label strip 11, so as to prevent the identity of the detected person from being unrecognizable.

Abstract

The invention discloses a nucleic acid detection and extraction device and extraction method, relating to the technical field of nucleic acid detection and extraction, comprising a sampling tube and a sampling mechanism, one end of the sampling tube is provided with a storage cavity, and the end of the sampling tube far away from the storage cavity is provided with a screw thread for storage A guide hole for connecting the storage cavity and the threaded storage tank is provided between the storage cavity and the threaded storage tank. The sampling mechanism includes a second magnet disc and a guide rod. The second magnet disc is slidably arranged inside the storage cavity. One end of the guide rod is fixedly inserted into the axial side wall of the second magnet disk, the other end of the guide rod slides through the guide hole and extends into the threaded storage groove, and the other end of the guide rod is fixedly sleeved with a threaded storage groove. Sterile cotton balls inside. The invention provides a nucleic acid detection and extraction device and extraction method, which is convenient for collecting sputum from the oral cavity of a tester, and sealing the collected samples for easy labeling and inspection, so that the detection efficiency is high and cross-infection is not easy to occur.
