Fully-enclosed pharyngeal sampler

Abstract

The invention discloses a fully-enclosed pharyngeal sampler. The fully-enclosed pharyngeal sampler includes a sampling body, wherein a swab mechanism, a camera mechanism and a tongue depressor mechanism are arranged in the sampling body, the front end of the sampling body is sleeved with a cover body, and the sampling body is divided into an upper-part control part and a lower-part hand-held part;the swab mechanism is installed on the upper wall of the control part, the camera mechanism is installed on the center of the front end of the control part, and the tongue depressor mechanism is arranged on the lower wall of the control part; and a rotary shaft in a torsion mechanism is fixed at the lower side of the tail part of the control part, the rotary shaft is sleeved by a torsion spring,and a push switch is arranged inside the upper end of the hand-held part. Through the sampler, the infection risks of the medical staff can be reduced effectively, meanwhile, the false negative rate of detection of throat swab specimens can be reduced, and COVID-19 and other respiratory infection diseases can be prevented and controlled effectively.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a hand-held fully enclosed pharynx sampler. Background technique [0002] At present, the criteria for the diagnosis and discharge of patients with SARS-CoV-2 COVID-19 are mainly based on the detection of viral nucleic acid. The sixth edition of the novel coronavirus pneumonia diagnosis and treatment plan is being implemented on a trial basis, and it is recommended that nucleic acid testing be carried out through sputum samples and lower respiratory tract lavage fluid samples. However, through the analysis of the pathological results of patients with new coronary pneumonia, it was found that inflammatory infiltration of mononuclear cells in the interstitium, mainly lymphocytes, was seen in both lungs, and bilateral diffuse alveolar damage with fibromyxoid exudation. This shows that the sputum of patients with new coronary pneumonia has a high viscosity and is not easy to disch...

Problems solved by technology

Some patients will inevitably have stress reactions such as coughing and sneezing after being stimulated by the swab. At this time, a large amount of gas that may contain virus droplets from the patient's respiratory tract will be sprayed directly on the face of the sampled medical staff, causing severe damage to the front-line medical staff. big hazard

Under the huge infection pressure, this open sampling method may also produce false negative test results caused by incomplete and incomplete sampling of individual samples, which is not conducive to controlling the spread and spread of this infectious disease
