Description

[Technical field]

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a medical visualized oral pharyngeal sample collector. [Background technology]

[0002] Normal people have normal flora in their pharyngeal areas. The bacteria in the pharynx come from the outside world and are not pathogenic under normal circumstances. However, bacterial or viral infections may occur when the body's systemic or local resistance is reduced or other external factors occur, leading to disease. Therefore, using a pharyngeal swab can remove pathogens from the pharynx for testing or isolation and culture. Combined with pharyngeal observation, it helps in the diagnosis and differentiation of diphtheria, purulent tonsillitis, and various bacterial and viral infectious diseases. Therefore, during medical consultations, doctors often use pharyngeal swabs to remove substances from the pharynx for nucleic acid testing, antigen testing, and sequencing.

[0003] Traditional throat swab collection and throat observation require medical staff to directly observe the patient's mouth, but sometimes the sampling quality is not high due to limited vision. Exhaled droplets and aerosols are one of the main transmission routes of pathogens (such as the new coronavirus). Therefore, the throat swab sampling of the existing technology is less controllable, and the risk of infection for medical staff and surrounding waiting personnel is higher during the process.
