Flutter device

A handheld device to facilitate clearance of mucus in hypersecretory lung disorders. Exhalation through the Flutter causes oscillations of expiratory pressure and airflow, which vibrate the airway walls, loosen mucus, decrease the collapsibility of the airways, and accelerate airflow. This facilitates movement of mucus up the airways.
