Disposable sample preservation device for throat swab detection

Abstract

The invention discloses a disposable sample preservation device for throat swab detection. The device comprises a preservation box, a limiting plate is arranged at the top of the inner wall of the preservation box, a disposable sampling tube is arranged at the top of the limiting plate, a sealing gland is arranged at the top of the preservation box, and tensioning and sealing mechanisms are fixedly connected to the left side and the right side of the preservation box. Through cooperative use of the preservation box, the limiting plate, the disposable sampling tube, the sealing gland, the tensioning and sealing mechanisms, a rotary sampling assembly, a connecting rod and an ice block placing plate, the problems that due to the fact that flip cover type preservation is adopted in an existingsample preservation device, the top of the preservation device is affected by dust when the preservation device is opened each time, the sealing performance is unstable, sample shaking can be causedby loosening of a flip cover, a disposable sample tube sealing plug is prone to loosening, sample cross sensing is caused, the preservation effect is reduced, and the use safety of medical staff is affected are solved, and the disposable sample preservation device has the advantages of being good in preservation effect and stable in sealing.

Description

technical field [0001] The invention relates to the technical field of sample storage devices, in particular to a disposable sample storage device for throat swab detection. Background technique [0002] Improving the ability to detect new crown nucleic acid, trying to expand the scope of detection, and strengthening nucleic acid detection work will not only help consolidate the results of prevention and control, maintain the health of the masses, but also help the rational flow of personnel, and promote the comprehensive resumption of work, production and school. How to improve the efficiency of COVID-19 nucleic acid detection is a hotspot of research by technicians in the field. It is recommended that 5 to 10 specimens be mixed for primary screening to improve detection efficiency and reduce detection costs. When a positive result is obtained, the samples corresponding to the positive result will be re-tested one by one to further screen the positive patients. This method ...

AI Technical Summary

Problems solved by technology

[0003] The problems existing in the existing sample storage device are: flip-top storage, every time it is opened, the top of the storage device will be affected by dust, and the sealing performance is unstable. The loose flip will cause the sample to shake, and the sealing plug of the disposable sample tube is easy to loosen. Sample cross-sensing reduces the preservation effect and affects the safety of medical staff
