The mechanical-assisted Sputum Elimination Appara is designed based on the principle of physical directional percussion. It helps the liquefied mucus in the small bronchi flow towards the larger bronchi, stimulating the cough center in the brain to facilitate the expectoration of sputum. Unlike manual back percussion, the low-frequency force of the mechanical device can penetrate through the skin and muscle tissue to reach the small bronchi. It is easy to operate, requires minimal effort, can be used in any position, and is well-tolerated by patients without causing fatigue.
