Device for sampling pharyngeal secretions of patients with new coronary pneumonia

technical field

The utility model relates to equipment for collecting secretions, in particular to a device for collecting pharyngeal secretions of patients with new coronary pneumonia.

Background technique

Novel coronavirus pneumonia is a high-risk emerging infectious disease, which spreads rapidly and is highly concealed. The onset is insidious, sudden and highly contagious, which has caused a major impact on people's health and life. Severe cases rapidly progress to critically ill and develop acute respiratory distress syndrome (ARDS), septic shock, difficult-to-correct electrolyte disturbances, and coagulation disorders, which lead to cytokine storm and multi-organ failure. . Studies have shown that the fatality rate of the disease is about 2.38%, and the basic infection number RO is 3.77. Normal human pharyngeal isthmus culture should have normal oral flora, without the growth of pathogenic bacteria. The bacteria in the pharynx all come from the outside world and are not pathogenic under normal circumstances, but infections can occur when the body's systemic or local resistance declines and other external factors lead to diseases. Therefore, pharyngeal swab bacterial culture can isolate pathogenic bacteria, which is helpful for the diagnosis of virus, diphtheria, suppurative tonsillitis, acute pharyngitis, etc. Clinical specimen collection includes throat swabs, lower respiratory tract specimens, bronchial secretions, bronchial aspirates, bronchoalveolar lavage fluid and serum specimens from patients. Specimens should be collected as far as possible from the respiratory tract specimens in the early onset of the case, especially the lower respiratory tract specimens, the acute phase serum within seven days of the onset, and the convalescent serum at intervals of two to four weeks. At the same time, the upper and lower respiratory tract specimens were collected, and the lower respiratory tract specimens were preferentially collected.

The clinical diagnosis of new coronary pneumonia ultimately requires a throat swab nucleic acid test. If it is positive, the diagnosis can be confirmed, but the negative result has typical clinical symptoms, imaging characteristics and contact history, and new coronary pneumonia cannot be ruled out. At present, throat swab nucleic acid detection is still the gold standard for clinical diagnosis. However, the throat swab examination may cause false negatives due to various factors (the degree of cooperation of the operator and the patient), so the sampling of throat swabs is very important. May cause missed diagnosis. It is very important to improve the inspection accuracy and completeness of pharyngeal secretions, especially the upper and lower respiratory tract secretions.

At present, because the disease has just appeared, there is no such product application in the hospital, and the provincial and municipal hospitals urgently need to solve the problem.

Detailed ways

At present, the testing methods for new coronary pneumonia are mainly through throat swabs and nasal swabs; because nasal swabs need to insert a plastic rod with a polypropylene fiber head into the nasal palate, but patients generally cannot tolerate insertion into the nasal passages. Throat swabs are commonly used. The existing throat swabs use two plastic rod swabs with polypropylene fiber heads to wipe the bilateral pharyngeal tonsils and the posterior pharyngeal wall at the same time. Only using plastic rod swabs not only has high risks and is likely to cause infection of medical staff, but also may cause missed diagnosis.

The utility model uses an intraoral support barrel 1, a material collection tube 2, and a material collection tube protective cover 3 to cooperate, and the use of the intraoral support barrel 1 minimizes the material collection pipe 2 contaminated with oral droplets.
