Upper respiratory tract sample sampling device and method

Abstract

The invention discloses an upper respiratory tract sample sampling device and method. The device comprises a packaging bag, wherein a storage pipe, a metering container, a flow guide pipe and a sealing bag are arranged in the packaging bag, a storage liquid is contained in the storage pipe, an identification code is attached to the outer wall of the storage pipe, the metering container is used for measuring drinking water or an isotonic saline solution, the liquid is fed into the oral cavity and the deep throat part of a to-be-detected human body to form a throat washing liquid, the flow guide pipe is used for introducing the throat washing liquid into the storage pipe, and the sealing bag is used for storing the storage pipe for sampling the throat washing liquid. According to the invention, the upper respiratory tract sample sampling device and method are suitable for self-sampling, safe, non-invasive and convenient to operate, the sample quality and the virus load can be guaranteed, personnel density and sampling personnel risks can be effectively avoided, and the sampling safety and efficiency are improved.

Description

technical field [0001] The invention relates to the detection of pathogenic microorganisms in the upper respiratory tract, in particular to an upper respiratory tract sample sampling device and method. Background technique [0002] For the detection of upper respiratory pathogens (such as the new coronavirus), nucleic acid detection and antigen / antibody immune detection are the main detection methods for the diagnosis of viral infection. The existing sample collection types are nasopharyngeal swabs, saliva samples, blood samples, etc. Studies have shown that different specimen types have different sensitivity to virus detection. When taking nasal swabs, patients have obvious discomfort, especially children, the elderly and other groups have a strong sense of discomfort when sampling, and swab sampling requires professionals, which leads to the gathering of people and increases the risk of infection of sampling personnel. Sampling of ordinary oral saliva samples shows that t...

Problems solved by technology

When taking nasal swabs, patients have obvious discomfort, especially children, the elderly and other groups have strong discomfort when sampling, and swab sampling requires professionals, which leads to the gathering of personnel and increases the risk of infection of sampling personnel

Sampling of ordinary oral saliva samples, the viral load in saliva is low in the early stage of the disease, and the risk of false negatives is high
