Tri-Balls Spirometer

Tri-balls incentive spirometer is a breathing lung exerciser which is a flow-oriented device, provides an indirect indicator "ball" of the patient's inspired volume. It be used to help strengthen respiratory musculature and to help restore and maintain lung capacity by encouraging a slow, deep breathing.Three color-coded balls in each chamber provide a visual incentive for the patient. Air flows into single channel, when it passes through the chamber, it raises each of the three balls depending on the flow inhaled per second.Specification: 12mmOD connector. Flow rates 600mLsec, 900mLsec, 1200mLsec. by using different colors of ball for easy to identify the flow rate.Material: AS for chamber, PE for ball and mouthpiece, and EVA for tubing.
