Sampling cabin for nucleic acid detection and nucleic acid detection method

Abstract

The invention provides a sampling cabin for nucleic acid detection, which comprises a cabin body capable of accommodating a to-be-detected person, and is characterized in that the cabin body is a cabin body with a cylindrical inner wall, the sampling cabin is provided with an air inlet for external air to enter and an exhaust port for exhausting gas in the cabin body, and the cabin body is provided with an air inlet and an air outlet. The sampling cabin further comprises a scavenging device capable of feeding external air into the cabin body and generating spiral ascending air flow, and the spiral ascending air flow is exhausted from the exhaust port. The invention also provides a nucleic acid detection method adopting the sampling cabin. Compared with the prior art, the device has the advantages that quick scavenging in the sampling cabin can be realized, and the sweeping rate is high, so that cross infection among detected persons in the detection process is effectively avoided; the installation is more convenient and simpler, the cost is lower, and the use safety is good.

Description

technical field [0001] The present invention relates to a nucleic acid detection device, in particular to a sampling cabin for nucleic acid detection and a nucleic acid detection method using the sampling cabin. Background technique [0002] As we all know, nucleic acid detection plays a key role in the diagnosis of new coronavirus infection. After the new coronavirus infects the human body, it will first multiply in the respiratory system. Therefore, it is possible to determine whether the human body is infected by detecting viral nucleic acid in sputum and nasopharyngeal swab. The virus, if the test comes back positive, it proves that the person has been infected with the virus. Therefore, confirmed cases, suspected cases and asymptomatic infections of new coronary pneumonia can be found through nucleic acid testing to ensure "early detection, early reporting, early isolation, and early treatment", quickly cut off the transmission route of the virus, and try to find out as...

AI Technical Summary

Problems solved by technology

However, this method of ventilation requires the use of air supply devices and exhaust devices at the same time, which is time-consuming and laborious to install, and the effect of rapid ventilation cannot be achieved by using the fresh air system, and the ventilation time will be relatively long, and the sampled personnel Many, one after another, until the air with the virus has not been replaced, the second and third people have been infected

This device still cannot solve the problem of cross-infection

In addition, most of the current sampling rooms are buildings with a square structure. The positions of the corners of the sampling room are not easy to be replaced by the fresh air system, which will cause residual exhaust gas, and there are still certain safety hazards after long-term use.

[0007] To sum up, the existing nucleic acid sampling stations still have low ventilation efficiency, long time, incomplete exhaust gas cleaning, and the risk of cross-infection of the tested subjects, which still needs to be further improved and improved

Although the testing staff are protected, there are a large number of tested personnel. The tested personnel are not protected and are susceptible to infection. As a result, the number of infected people will increase, which will overwhelm doctors and greatly increase social workload.
