Technical Field
The invention relates to a medical specimen collecting instrument, in particular to a nasopharynx swab accurate sampling device.
Background
Since 12 months 2019, the prevalence of novel coronavirus pneumonia Covid-19 (hereinafter referred to as new coronary pneumonia) has exploded in the world, and the pathogenic diagnosis by nucleic acid detection is the key to controlling disease transmission and diagnosis and treatment. Some suspected patients with new coronary pneumonia in virus nucleic acid detection show negative detection for a few times, but the suspected patients with new coronary pneumonia finally show positive detection after multiple detections, and the false negative phenomenon appearing in virus nucleic acid detection is of concern. A large amount of clinical practices find that the positive rate of simple throat swab specimen nucleic acid detection is low, the scheme for diagnosis and treatment of pneumonia infected by novel coronavirus (trial fifth edition) issued by the national Weijian Commission on 2, 8 days has been updated to collect the throat swab of the specimen into the throat swab, and in order to improve the positive rate of detection, the collection of the same patient of the throat swab and the oropharynx swab is suggested, and then the collection is carried out in the same collection tube.
A research published by Medrxir on the near day is that respiratory tract samples such as nasopharyngeal swabs, oropharyngeal swabs, sputum and bronchoalveolar lavage fluid are collected from a patient who is diagnosed with new coronary pneumonia, an approved kit is adopted to detect virus nucleic acid, and the result is analyzed by combining sampling date and clinical information. The early virus is distributed in the upper respiratory tract, the oropharynx part is influenced by diet and swallowing, the virus part is eliminated, and the nasopharynx swab has long sampling time and no pharyngeal reflex, so that more sufficient samples can be obtained. Therefore, collecting nasopharyngeal swabs is currently the most convenient and popular method.
However, the clinically found suspected new coronary pneumonia patients are negative in the first few tests, but are positive finally after the multiple tests, and besides the development of the disease course of the patients, the reason is that the following defects and shortcomings exist in the current virus nucleic acid detection process: 1) some medical staff are not familiar with the anatomical structures of the nasal cavity and the nasopharynx, the angle and the depth during sampling are not accurate, the pharyngeal swab does not contact the nasopharynx at all, and only secretion of the nasal cavity can be collected during blind sampling; 2) because the operation is inaccurate and angle and degree of depth need be adjusted repeatedly, cause patient's misery when sampling, the reaction is great: 3) medical personnel usually face the patient during sampling, and the risk of droplet and aerosol infection exists.
