Flutter VRP1 Respiratory therapy device

The FLUTTER is a small, lightweight respiratory training device with secretion mobilizing effect. It does not require any force and can be easily used anytime and anywhere. During the user's exhalation into the device, the steel ball inside the device starts to vibrate. The exhalation pressure pushes the ball up against the funnel wall, air escapes through the resulting opening, the exhalation pressure decreases and the outflowing air is accelerated. The vibration is directed back into the lungs thereby loosening mucus in the respiratory tract, which is coughed up after use. The FLUTTER enables a change in exhalation pressure and oscillating frequency.
