AI Technical Summary
Technical Problem
Existing airway patency devices can cause airway wall adhesion and damage due to changes in suction pressure caused by sputum accumulation during suctioning, posing a safety hazard.
Method used
The system employs an elastic membrane in conjunction with an orifice size control mechanism. The orifice size is automatically adjusted by the elastic membrane and orifice size control mechanism within the suction orifice. Combined with a rotation mechanism and air pressure compensation components, the system achieves adaptive adjustment and rotational cleaning of the suction orifice, thus avoiding airway damage.
Benefits of technology
It effectively avoids airway wall adhesion caused by sputum accumulation, reduces airway damage, and improves suctioning efficiency and safety.
