Technical Field

The invention belongs to medical equipment, in particular to a protective device for pharynx test sub-sampling and oropharynx examination.

Background

Nucleic acid examination is the main detection means for diagnosing the new coronary pneumonia at present, and throat swabs are the main sampling method for diagnosing the new coronary pneumonia virus infection at present. However, during the operation, the medical staff needs to be in close contact with the patient, and the patient can generate a large amount of spray or aerosol due to cough, vigorous breathing and the like, so that the risk of cross infection is high. In addition, in the process of collecting throat swabs, due to the difference of levels of different medical staff, fear of psychology and standardization of collection operation, the quality of swabs is different, false negative easily occurs, the judgment of the state of an illness is influenced, and even epidemic prevention and control are influenced.

The standard collection of throat swabs is to examine the oropharyngeal cavity of a patient, open the mouth of the patient to breathe naturally and relax, and examine the pharyngeal cavity under good illumination, such as when the back of the tongue crosses a high shieldable region, the back of the tongue needs to be depressed by a tongue depressor to expose the pharyngeal cavity. The prepared pharyngeal swab collecting tool is held in hand, and the sampling is carried out on bilateral faucial arches, tonsils and the posterior pharyngeal wall by wiping. In the process, many examinees can generate nausea and reflex, individual sensitive people have poor pharyngeal cavity exposure, nausea, vomit, cough, secretion increase and sneeze, a large amount of spray and aerosol can be generated, the medical personnel and the surrounding environment are greatly threatened, and cross infection is easily caused. Although medical staff dresses protector, and the sampling finishes can take off the gloves and wash hand, but the droplet pollutant on protective clothing and the protective mask is difficult to wash, also is difficult to change, so carry out the sampling of pharynx swab for next person of being examined immediately, probably cause cross infection. Therefore, how to more scientifically and accurately perform throat swab sampling and reduce the risk of cross infection is a technical problem needing emergency treatment at present. In order to solve the key technology, an expert team cooperates to research and develop the pharyngeal swab sampling robot in an emergency, and the pharyngeal swab is collected by the pharyngeal swab sampling robot, so that medical staff can be effectively prevented from being infected, the normalization of biological sample collection is improved, and the quality of a sample is ensured. With the continuous spread of epidemic situation, the new coronary pneumonia epidemic situation has evolved into a global big outbreak situation, and the necessity and difficulty of biological sample collection and the protection of medical staff urgently need the popularization and application of the remote control biological sample collection robot. However, the pharyngeal swab sampling robot is expensive in manufacturing cost, complex to operate and difficult to popularize recently. In view of the situation that the current new coronary pneumonia epidemic situation is tense, the nation emphasizes external defense input, internal defense rebound, and particularly strictly prevents the input of overseas epidemic situations, and a large number of pharynx swab sampling tasks are arranged on each entry port and isolated observation areas, so that the research and development of a simpler, more convenient and more effective pharynx swab sampling protection device is very urgent.

In addition, the epidemic situation of new coronary pneumonia in China is relieved at present, the work is repeated in various places, the normal diagnosis and treatment order is restored by medical units, but still a fever patient or an upper respiratory tract infection patient and a possible asymptomatic new coronary pneumonia virus infected person go to the outpatient service of a hospital to see a doctor, and partial departments of the hospital, particularly otorhinolaryngology department, stomatology department, ophthalmology department and respiratory department, are still high-risk departments. Because the protection equipment of medical staff is reduced to primary or secondary protection at this time, the protection equipment is not tight enough, and patients in the face of clinic may have asymptomatic new coronary pneumonia virus carriers or latent new coronary pneumonia infectors, and the risk of cross infection still exists in the process of examining and treating in the clinic. When the inspection and operation of the oropharynx are carried out, medical staff need to be in close contact with a patient, the condition of the oropharynx needs to be inspected clearly, particularly, when a tongue spatula is used for inspecting the pharyngeal cavity, the patient can feel sick and coughing, the nasal cavity can be inspected to cause the patient to sneeze, a large amount of droplets and aerosol are generated, the threat to the medical staff lack of tight protection is huge, and the risk of cross infection is caused to other patients in clinic. Therefore, oropharyngeal examination shields are also important to protect medical personnel and patients from medical visits. In order to solve the above problems, the present invention makes the following design:
