Description

Technical Field

[0001] The invention relates to the field of medical and health protection equipment, and in particular to a device for collecting and protecting pharyngeal swabs with the help of a bronchoscope. Background Art

[0002] COVID-19 or other infectious viruses are highly contagious, and pharyngeal swab collection is an important means of nucleic acid screening for COVID-19 or other infectious viruses. Currently, nucleic acid testing of relevant personnel is an important means of testing and screening, so the number of nucleic acid screening (pharyngeal swab collection) has increased significantly. Although the protection requirements for collectors are very high and the collection environment has been greatly improved, many grassroots hospitals or medical units are limited by objective conditions such as funds and venues. The subjects are currently in the same sampling area at the same time. If there are potential infected people during the sampling process, coughing, sneezing, and vomiting caused by irritation to the pharynx will produce a large number of virus-containing droplets or aerosols that remain in the air, which will inevitably increase the risk of subsequent infection of the subjects.

[0003] When collecting throat swabs, the collection site and the quality of the collected throat swabs may deviate due to the influence of the collector's line of sight, thus affecting the results of nucleic acid testing; if the collector is not proficient or the posterior pharyngeal wall of the person being collected is not fully exposed, the person being collected may even be at risk of injury. After the throat swab is collected, the collected specimen is exposed to the air during the period of transfer from the person's mouth to the virus culture fluid, which also increases the risk of infection for the collector.

[0004] The patent application number is CN202020285678.X, and the patent name is Self-cover type throat swab collection protective mask. Its technical features are: one side of the mask body is an open end, and the other side is an arc-shaped plastic transparent cover, and the arc-shaped plastic transparent cover is provided with a through hole, and a rubber hose is bonded at the position of the through hole, and the other end of the rubber hose is a closed end.

[0005] The patent application number is CN202020264901.2, and its name is a throat swab collection protective mask. Its technical feature is that the surface of the transparent mask is curved, a collection through hole is opened in the middle, and a sponge strip is horizontally arranged on the inner wall of the upper end of the transparent mask.

[0006] Although the technical solutions in the above two patent application documents are both related to protective masks for throat swab collection, they can only perform the same functions as masks, so their protective functions are too single.

[0007] The patent application number is CN202011199243.4, and the patent name is a contactless intelligent throat swab collection workstation and its use method. Its technical solution mainly protects a contactless intelligent throat swab collection workstation and its use method, and there is not much description about the collection protective mask. Although it is relatively safe and fully functional during collection, it does not have visibility, has high requirements for collectors and is expensive, and is limited in primary medical institutions.

[0008] The patent application number is CN202011136634.1, and the patent name is A sampling tube for both sampling and adding samples and a method of use thereof. Its technical solution mainly protects a sampling tube for both sampling and adding samples and a method of use thereof. It is only an improvement on the sampling tube for collecting specimens and has strong limitations. Summary of the invention
