Virus collection tube for novel coronavirus nucleic acid mixed collection detection technology

Abstract

The invention discloses a virus collection tube for a novel coronavirus nucleic acid mixed collection detection technology. The virus collection tube comprises a collection tube body and a tube cap; the tube cap is detachably connected to the collection tube body; the collection tube body is internally provided with an inwardly concave cylinder; An annular space for placing a plurality of pharyngeal swab heads is formed between the concave cylinder and the tube wall of the collecting tube body; an auxiliary pharyngeal swab breaking piece is connected to the inwardly concave cylinder and is formed by connecting a plurality of pharyngeal swab breaking ribs; and virus preserving fluid is arranged in the collection tube body. The annular space formed between the inwardly concave cylinder arranged in the collection tube body and the tube wall of the collection tube body is utilized, and it is guaranteed that enough space is provided for containing 10 pharynx swab heads. The collection tubeis arranged on a high-frequency swirler, so that the ten pharyngeal swab heads vibrate in the collection tube and rotate around the inwardly concave cylinder at the same time, and epithelial cells onthe pharyngeal swab heads can be fully eluted into a collection tube preserving fluid.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a virus collection tube for the novel coronavirus nucleic acid mixed collection detection technology. Background technique [0002] Pharyngeal swab collection is currently the main method for collecting specimens for nucleic acid testing of the new coronavirus. In the prior art, a single throat swab or multiple throat swabs collected are put into a virus collection tube, and the cap of the tube is tightened to be marked and then sent to the laboratory for follow-up inspection. [0003] Currently, there are two main methods for collecting specimens for nucleic acid testing of the new coronavirus: single collection and mixed collection. Single collection, because of the high detection efficiency and low cost, is no longer suitable for use in large-scale crowd detection of new coronavirus nucleic acid; mixed collection, the 10-in-1 mixed collection technology...

Problems solved by technology

Single collection, because of the high detection efficiency and high cost, is no longer suitable for use in large-scale crowd detection of new coronavirus nucleic acid; mixed collection, the 10-in-1 mixed collection technology is the most effective specimen collection method for large-scale crowd detection of new coronavirus nucleic acid

However, the spatial structure of the 10-in-1 virus collection tube used in the current 10-in-1 mixed collection technology is unreasonable and small, and it is impossible to ensure that there is enough space between the 10 swabs; therefore, the subsequent processing of the collection tube with a high-frequency vortex At this time, the vibration range of the 10 throat swabs in the collection tube is limited, and the vortex time must be prolonged in order to effectively extract the nucleic acid of the specimen, which has caused certain obstacles to the extraction process of the nucleic acid of the specimen
