Respiratory Trainer, 3-Ball Breathing Exerciser
A pulmonary rehabilitation device with a 3-ball indicator system that gives clear visual feedback during breathing exercises to build lung capacity and respiratory strength over time.
The Respiratory Trainer with 3-Ball Indicator System is a pulmonary rehabilitation device designed to improve a patient's lung capacity and respiratory strength through controlled inhalation exercises. As the patient breathes in through the device, three colour-coded indicator balls rise according to their inspiratory flow rate, giving immediate, easy to understand visual feedback on how strongly and steadily they are breathing.
This feedback helps patients pace their breathing correctly during deep breathing therapy sessions, rather than guessing at their effort without any reference point. Respiratory therapists, physiotherapists and post-surgical recovery teams use trainers like this with patients recovering from chest surgery, respiratory illness or reduced lung function due to prolonged bed rest, since regular use encourages fuller lung expansion and better overall breathing mechanics.
Because the device is simple to use and gives clear visual targets, patients can also continue their breathing exercises independently at home between clinical appointments as part of an ongoing respiratory rehabilitation programme.
