Transparent Portable Three Balls Spirometer Breathing Trainer Incentive Spirometer
A three-ball incentive spirometer is a breathing-exercise device with a transparent chamber arrangement for visual feedback during inhalation. It is used in clinician-directed breathing-exercise and respiratory-rehabilitation workflows. This mechanical breathing trainer should be distinguished from diagnostic spirometers that measure lung-function parameters or generate pulmonary-function reports.
