Description

An oropharyngeal airway with suction

technical field

The utility model relates to the technical field of medical devices, in particular to an oropharyngeal ventilation tube with phlegm suction.

Background technique

Clinical application of oropharyngeal airway is a simple and quick way to keep the airway open. It is mainly used for airway obstruction caused by weakened gag reflex or relaxation of jaw muscles in unconscious patients, and to prevent injury in patients with trismus. The lips and tongue, and the placement of the oropharyngeal airway at the same time can reduce the damage of the patient's oral cavity and airway mucosa, and prevent the tongue from falling back, which is beneficial to suctioning. Stress and slowing of heart rate have an adjunctive therapeutic effect on lowering blood pressure in patients with cerebrovascular accident.

Existing oropharyngeal air tubes in clinical use are generally mainly composed of an oropharyngeal airway, an occlusal portion and a baffle. When in use, after placing the oropharyngeal airway, the tongue is pressed downward with the end of the oropharyngeal airway to support the tongue. The palatal arch and uvula can prevent the tongue from falling back and achieve the purpose of opening the airway. The placement of this oropharyngeal ventilation tube will cause the patient to open the mouth, increase the saliva, make it difficult to swallow, and easily cause aspiration and saliva overflow. It is easy to aggravate the increase of respiratory secretions of patients and increase the burden of attracting nurses, so there is a Chinese utility model patent with the authorization announcement number CN210020718U, which discloses an oropharyngeal airway with a sputum suction function, including an oropharyngeal ventilation tube and a sputum suction tube. , tooth pad, protruding flange and flange fixing hole, wherein a suction tube is arranged on the side wall of the oropharyngeal ventilation tube, and the ventilation hole on the oropharyngeal ventilation tube can be used as a breathing auxiliary pipeline, and the outer surface of the suction tube is The interface part is connected to the inlet of the sputum suction device, and the sputum and saliva of the patient can be drawn away through the saliva penetration hole provided in the pharyngeal cavity of the sputum suction tube, so as to avoid the patient from turbulent saliva flow, poor breathing, and even drooling caused by oral secretions.
