High-Capacity 5000mL Incentive Spirometer and Lung Exercise Trainer

High-Volume 5000mL Precision Measurement: Features an expansive 5000mL measurement scale, allowing adults to accurately track deep inhalation capacity and monitor progressive improvements in lung volume.

Dual-Indicator Visual Feedback System: Equipped with both a primary volume scale and a secondary ball flow rate indicator to help users maintain the correct steady inhalation speed for optimal lung expansion.

Professional Post-Surgical Recovery Support: Designed as a clinical-grade tool to help clear airways and restore respiratory function after surgery, or for daily maintenance of peak lung performance.

Adjustable Difficulty for Progressive Training: The intuitive visual markers allow users to set personal goals and gradually increase their inhalation strength through consistent daily breathing exercises.
