Introduction of Cough assist device vest airway clearance system Airway Clearance System with good quality
The high-frequency chest wall oscillating sputum expectoration instrument consists of a pneumatic pulse generator, an air hose, an inflatable vest and an emergency stop switch. The pneumatic pulse generator inflates and deflates the vest at high speed through two air hoses connected to the inflatable vest (or chest strap). When the frequency reaches a certain height, it will cause the chest cavity under the vest to oscillate, similar to The movement of a slight cough. The high-frequency oscillating chest wall simulates the oscillating action of the chest wall caused by coughing, relaxing and liquefying mucus and metabolites on the mucosal surface of the expiratory airway, making it smaller and looser and falling off. When the sputum moves from the bronchus to the main trachea, coughing Or artificial suction to excrete it from the body to achieve the therapeutic effect.
