Product Introduction：

Product principle：

The host generates high-frequency air pulses through rapid inflation and deflation. The air pulses inflate the airbag vest through the catheter to generate vibrations, thereby compressing the chest cavity at a certain frequency, causing the airflow to quickly pass through the lung lobes and respiratory tracts, and promoting mucus and metabolites on the mucosal surface to get loose, be liquefied, fall off, and move to the mouth. After reaching the mouth, phlegm  is discharged through normal cough or negative pressure suction.
