Description

A suction device for oral cavity and subglottic

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an aspirator used for oral cavity and subglottic area.

Background Art

Tracheotomy or endotracheal intubation is a way to establish an artificial airway for critically ill patients. To ensure the airtightness of the airway and prevent airway secretions from entering the lungs through the airway, an air bag is usually installed near the glottis to seal the airway. The patient's mouth is rich in glands, which secrete a large amount of oral secretions every day. Generally, these oral secretions will accumulate on the top of the air bag, but when the patient has a choking reaction, the patient's trachea will expand, the air bag will lose its sealing function, and the oral secretions will enter the airway and cause lung infection, which can easily lead to an increase in the patient's mechanical ventilation time, hospitalization time, and hospitalization costs.

This utility model patent is provided with a subglottic suction tube and a sputum suction tube for suctioning secretions under the glottis and in the oral cavity of the patient. However, the sputum suction tube of this utility model is usually directly arranged in the oral respiratory tract of the patient. Severely ill unconscious patients are more likely to bite the sputum suction tube with their teeth clenched, and the occlusion of the sputum suction tube will lead to poor oral suction effect.
