The Incentive Spirometer Respiratory Device is designed to help patients improve lung function and capacity through controlled breathing exercises. It encourages slow, deep breaths that expand the lungs, prevent respiratory complications, and aid in recovery after surgery or prolonged bed rest. This device is especially beneficial for individuals recovering from pneumonia, chest injuries, or post-operative conditions. Lightweight, easy to use, and clinically tested, the incentive spirometer is an essential tool for physiotherapy clinics and home-based respiratory rehabilitation. It assists in maintaining optimal lung health, reducing mucus buildup, and promoting better oxygen intake.
