5000ml Visual-Feedback Breathing Trainer

A precision-engineered incentive spirometer delivering simultaneous volume measurement (0–5000ml) and dynamic flow rate feedback. Physical specs: 22 cm × 9 cm × 9 cm; weight 180 g. Body material is certified break-resistant plastic—non-toxic, odourless, and compatible with 70% isopropyl alcohol wipes. Includes replaceable filter cotton, snap-fit mouthpiece, and kink-resistant tube—all separable for complete cleaning. The flow indicator responds instantly to inspiratory velocity: rising above upper mark signals excessive speed (risking dizziness or airway irritation); falling below lower mark indicates inadequate effort (limiting therapeutic benefit). Centring the marker confirms optimal pace—supporting sustained, rhythmic breathing patterns essential for oxygen saturation and postural drainage. Designed for continuity of care, it suits hospital discharge planning, GP-endorsed home programmes, school-based wellness initiatives, and family-shared respiratory health routines. No consumables needed beyond optional replacement filters; all components are reusable indefinitely with proper hygiene.
