Abstract
The invention provides a novel collector for nasopharynx swabs of infectious disease patients and a using method thereof.
Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a novel collector for nasopharynx swabs of patients with infectious diseases and a using method thereof.
Background
The viral load of the upper respiratory tract of a patient with new coronary pneumonia is higher in the early stage of onset, the viral load begins to decrease along with the time, the patient with the new coronary pneumonia can detect the higher viral load shortly after the symptom onset, and the nucleic acid detection and screening specimens of a patient with mild pneumonia and a suspected case mostly adopt deep expectoration or nasopharyngeal swabs. The main transmission route of the novel coronavirus is via droplet, and the transmission mode is similar to that of pneumonia: cough, expectoration and even respiration all transmit the disease. The method is a typical infectious person, and pharyngeal swab sampling detection, is one of important links for resisting new coronary pneumonia, and is also a key technical support for accurate diagnosis or elimination of close contact persons and suspected patients. When a nasopharynx swab specimen is collected, the collection depth is a key, a patient has cough, sneeze and the like in the sampling process, the existing throat or nose swab collector cannot effectively protect the safety of the collector, and droplets or aerosol generated by the reaction of cough and the like after stimulation of the patient increases the infection rate of medical care personnel; the splash generated during the specimen collection can reach 2 meters, which causes serious pollution to the surrounding environment of a ward and has potential safety hazard. Medical samplers are at very high risk and psychological stress can be great.
