Abstract: The Flutter is a medical handheld device, which is designed for patients suffering from various lung diseases. This device is designed to mobilize the excessive secretion of in the direction of airways and helps to loosen the mucus from the lungs and removed. Sometimes mucous in the lungs can become thick and hard to clear from the airways. If this mucous stays in the airways, it could block them, making it harder to breathe. Infection is also possible when mucous stays trapped in the airways. When one breathes out through the Flutter, it causes the ball inside to bounce. This bouncing causes increased pressure inside the chest and sends vibrations down through the airways. The combination of increased pressure and vibrations helps the mucous move from the lungs into the airways where it can be coughed out. Some patients cannot blow very forcefully, so our project is designed in such a way that the resistance of the blow is measured using a strain gauge. If the value goes below the certain threshold, limit the beep sound is heard and a light indication is provided so that we can find whether the patient should blow out even more faster. This device is small, portable, and easy to use and has no side effects.
