A mouth-containing respiratory droplet collection device and method of use

Abstract

The invention discloses a mouth-containing air tube spray collecting device and a using method. The device comprises a double-layer body with a blunt circular end, and further comprises a blowing mechanism, a opening and closing mechanism and a collecting mechanism; compared with the prior art, the device is simple in structure and easy to use, has the advantages of accurate collection, no pain, no trauma and the like, is not contaminated by oral pathogens, and ensures the accuracy of test results, a limit device is arranged, and the device can facilitate the operation of medical personnel, reduce the difficulty of work, and avoid the cause of operation errors.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an oral respiratory droplet collection device and a method of use. Background technique [0002] When a patient seeks medical treatment and needs to collect lower airway droplets from the respiratory tract, the lower airway droplets are usually collected by swab swabbing. This method has obvious shortcomings. Pathogens in the oral cavity can easily contaminate the cotton swab, resulting in inaccurate test results. , which directly affects treatment. There are also individual methods of extraction by intubation. This method is difficult to collect pathogens in the lower airway of the respiratory tract, and it is more painful. There are reports abroad that lung puncture sampling is used for testing. Although this method makes the test results accurate and does not produce pollution, it is painful and prone to trauma.
