Description

Movable sampling chamber

Technical Field

The utility model belongs to the technical field of the medical science sampling and specifically relates to a portable sampling room.

Background

At present, nasopharyngeal swab sampling is to adopt pharyngeal and nasal secretion of a patient and perform bacterial culture so as to detect whether the patient is infected with respiratory diseases. Currently, a physician needs to pay attention to many details when collecting nasopharyngeal swabs. For example, the patient does not need to stand right opposite to the sampling object, but stands on the side of the sampling object, so that the medical staff can avoid the situation in time if the patient coughs, sneezes and the like in the sampling process, and the risk of infection is reduced. Because the doctor needs to extend a long cotton swab into the pharyngeal tonsils and the posterior pharyngeal wall of the two sides of the sampling object in parallel with the palate, lightly wipe and stay for 5 seconds to adsorb secretion in the collection process, the process can cause the patient to feel discomfort in the pharynx, and virus-carrying aerosol can be generated in case of cough or vomit, which is dangerous for the collector. Although the doctor can wear certain protective measures during the sampling process, the doctor still has unobstructed contact with the sampling object, and once the sampling object vomits, secretion can be splashed directly to the doctor, so that the risk of infection exists.

Therefore, it is necessary and urgent to develop a method for blocking a specimen from a doctor in a closed manner, which can prevent the doctor from contacting with saliva, vomit, etc. carrying viruses, which may be generated from the specimen, and can block aerosol carrying viruses, thereby ensuring the personal safety of the doctor.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: overcome prior art's not enough, provide one kind and can fully keep apart doctor and sample object, avoid doctor direct contact to sample object's droplet, vomitus or carry the aerosol of virus, reduce the risk that the doctor is infected, fully ensure personal safety and carry convenient portable sampling room.
