Lung Exerciser, Tri Ball (Spirometer), For Diagnose Asthma Use

A "lung exerciser, tri ball (spirometer)" is a medical device used in respiratory therapy and pulmonary rehabilitation. It is a type of spirometer designed to help patients improve their lung function and respiratory health.

This device typically consists of a clear plastic chamber with three balls inside, each representing a different level of inhalation effort. As the patient inhales deeply, the balls rise in the chamber, indicating the volume of air inspired and the strength of the inhalation.

Lung exercisers with three balls provide visual feedback to patients, allowing them to monitor their progress and gradually increase their lung capacity and respiratory muscle strength through controlled breathing exercises. These spirometers are commonly used in clinical settings as well as for home-based respiratory therapy programs.
