Therapeutic Incentive Spirometer with Digital User-Interface

This project addressed limitations in conventional incentive spirometers, which lack a standard way to monitor patient use and technique and require separate procedures for oxygen or albuterol administration. The work focused on a therapeutic incentive spirometer prototype that combined a mechanical spirometer, digital user interface, and integrated inhaler/administration port in one device. The proposed design reduced device size, improved handle ergonomics, repositioned the visual performance indicator, and added a port for oxygen and albuterol delivery. Its electronic interface was intended to track inhalation targets, detect diaphragm movement, display successful sustained maximal inhalation, count completed breaths, and provide reset, power, reminder, motion-sensing activation, and rechargeable power functions. The prototype was designed to demonstrate the fit, feel, form, and function of a market-ready medical device while supporting future evaluation of a more consolidated process for respiratory therapy and patient compliance tracking.
