The simple-to-use, lightweight, pipe-shaped
respiratory physiotherapy device
is designed to help promote and maintain
bronchial hygiene by vibrating the airways,
which loosens mucus from the airway walls.
A stainless steel ball inside the device oscillates
when used, and once its oscillatory
frequency matches the natural frequency of
the patient’s chest wall and abdomen, it produces resonance, which,
in turn, enhances sputum clearance.
