Lung Flute is a medical device that uses sound waves to break up mucus in the chest cavity.
Lung Flute is a simple medical device that uses sound waves to break up mucus in the chest cavity. By blowing into the flute ten times a vibration is sent into the chest cavity which breaks up congestion, enabling users to cough it out and breathe better. The $40 Lung Flute is one of Popular Science’s Best Innovations of 2009.
Popular Science explains:
In healthy lungs, hairlike cilia on the bronchial walls wiggle in unison to ferry mucus up the trachea and into the mouth, where it can be swallowed or spit out. Patients with COPD, however, secrete more mucus than the cilia can remove, and thick gobs of the stuff build up in the lungs, making them a breeding ground for bacteria that can lead to pneumonia. Vigorous coughing can help dislodge it, but many sufferers require drugs to open their airways; some need help from oxygen tanks. Annually, the combined cost of treatment totals upward of $27 billion.
