Interventions

Type	Name	Description
DEVICE	CAREWAY	CAREWAY , A high-frequency chest wall oscillation device in the form of a vest (Todaki) is used in patients who require clearance of mucus retained in the lungs, providing high-frequency chest wall vibrations to dislodge sputum adherent to the bronchial walls and facilitate removal of secretions.
DEVICE	EM HFLS CWSE(Nine-Motor)	This bed-type medical device delivers vibrational energy across the chest wall for patients with respiratory conditions aiding in the clearance of accumulated sputum in the airways and lungs. It incorporates nine electromagnetic high-frequency, low-strain vibration motors to produce distributed vibrational energy, which is applied via the chest wall oscillation plate to multiple lung regions, enhancing comprehensive sputum clearance through multi-point oscillation
DEVICE	EM HFLS CWSE(Single-motor)	This bed-type medical device applies vibrational energy to the chest wall of patients with respiratory diseases , to facilitate sputum clearance from the airways and lungs. The device employs a single electromagnetic high-frequency, low-strain vibration motor that generates vibrational energy, which transmits through the chest wall oscillation plate directly to the patient's chest, promoting effective mucus mobilization via targeted oscillations.
