Multifunctional nasopharynx swab collecting device and method for avoiding cross infection risk

Technical Field

The invention relates to the technical field of medical equipment manufacturing, in particular to a multifunctional nasopharynx swab collecting device for avoiding cross infection risks.

Background

A novel coronavirus epidemic situation which is as rare as the outbreak of the coronavirus in 2019 worldwide is named as COVID-19 and is characterized by strong infectivity and high transmission speed. The main transmission path of the virus is respiratory droplets, close contact and the like, wherein the long-term exposure of the virus strain to aerosol in the air environment is also a large inducer causing the transmission of the virus strain.

In order to inhibit the malignant spread of epidemic situations, nucleic acid detection is particularly important at present. Nasopharyngeal swabs are important collection methods in conventional nucleic acid detection processes. However, in the process of collecting viruses by using a conventional nasopharyngeal swab, an independently packaged sterile cotton swab is clinically used to deepen the nasal cavity and the deep throat, after sampling is completed, a large amount of bacterial viruses can be attached to the head of the sampling cotton swab, and at the moment, the sampling cotton swab can be easily exposed in the air for a long time due to the problems of manual operation, space moving and the like, so that the risks of virus propagation and cross infection are greatly increased. In addition, during the clinical sampling process, one hand holds a sterile cotton swab, and after the cotton swab takes out a specimen, the other hand needs to loosen the virus culture tube, which undoubtedly increases the exposure time of the virus in the air and the complexity of the operation.

The above problems are very serious, considering the complexity of the operation and the differences in the reaction capacity of the sampling personnel, and it is not completely possible to place the swab immediately in the virus culture tube, which does not meet the "rapid" sampling criteria specified in the virus detection protocol. In view of the characteristics of high virus propagation speed and the problems of different reaction capacities of operators and the like, the development of a multifunctional nasopharyngeal swab collecting device for avoiding the risk of cross infection is urgently needed to reduce the risk of virus cross infection between medical staff and tested staff and the complexity of nucleic acid sampling operation, which is particularly important for precise medical treatment and is a hotspot of the current society.
