Description

Closed throat swab sampling device
Technical Field
The invention relates to a medical instrument, in particular to a closed throat swab sampling device.
Background
The COVID-19 which seriously harms the new coronary pneumonia in China at present has the advantages of emergency onset, quick propagation, clear diagnosis as soon as possible, etiology or isolation treatment, and decisive effect on controlling epidemic situation.
The throat swab is a medical examination means for detecting the etiology of respiratory diseases, samples are obtained from the throat of a patient to carry out relevant detection, and the throat swab is easy to operate, economical and convenient, so that the throat swab is clinically and generally used. The detection of the nucleic acid of the pharyngeal swab is an important basis for the accurate diagnosis of the new coronavirus pneumonia, many suspected cases are subjected to the nucleic acid examination of the pharyngeal swab, and sometimes even repeated sampling and detection of the pharyngeal swab are required, the reliability of the detection result is closely related to the correctness of the sample collection, the patient who is partially diagnosed with the new coronavirus pneumonia is subjected to the nucleic acid detection for several times and is detected to be positive finally, and a great reason is probably related to the incorrect sampling of the pharyngeal swab.
Carry out the collection of pharynx swab clinically, adopt an aseptic cotton swab of independent packing, patient opens big mouth when carrying out the sample collection, and medical staff openly faces the open respiratory track of patient, and the left hand uses the tongue depressor to push down the tongue in oral cavity to see patient's pharynx back wall and near tonsil position clearly, the right hand sends into the oral cavity with the cotton swab and accurately acquires the sample censorship in throat corresponding part with the aseptic cotton swab of head end. Therefore, for virulent infectious diseases transmitted via the respiratory tract, pharyngeal swab sampling is the most dangerous operation for medical personnel in the clinic. Because when the mask is taken off by a patient and the mouth is opened to face the breathing of medical staff, the airway of the patient is directly communicated with the outside, the exhaled gas has high-concentration virus, and the swabs directly stimulate the pharynx of the patient, severe cough and nausea of the patient can be caused, and the virus load in the exhaled gas is very high. Medical staff is exposed in the environment in a short distance and can possibly inhale pathogenic bacteria exhaled by a patient, when the pathogenic bacteria with strong infectivity face the pathogenic bacteria with strong infectivity, the medical staff directly collecting the throat swab specimen can be subjected to a great infection risk, and a large amount of viruses rapidly released by an open airway of the patient can be mixed with respiratory secretions to form an aerosol state in a local environment and exist for a long time. Therefore, there is a frequently saying that the patient cough and the doctor tremble three times when collecting the throat swab specimen.
How to protect medical staff from being infected when collecting throat swab specimens and how to collect specimens correctly as far as possible, at present, no good solution exists at home and abroad. The risk of infection of medical personnel is still very high despite the corresponding protective equipment. There is therefore a clinical urgent need to improve the complete medical personnel protection scheme including safe and accurate pharyngeal swab sampling.
