Open-source, low-cost, web-guided spirometer Team: Jeremy Glynn – Team Leader Jeremy Schaefer– Communications Andrew Dias – BWIG Andrew Bremer – BSAC Week: January 6- February 12, 2009 Client: David Van Sickle, PhD Dept. of Population Health Sciences UW School of Medicine and Public Health Phone: (608) 719-9531 e-mail: [email protected] Advisor: Mitch Tyler 2156 Engineering Centers Building Phone: (608) 262-5112 e-mail: [email protected] Problem Statement Spirometers are used to diagnose many pulmonary diseases including chronic respiratory diseases that affect approximately 300 million people. Many of these people do not have access to a spirometer because current models are expensive and operation requires the presence of a trained technician. The purpose of this project is to develop a low-cost spirometer capable of measuring lung flows and volumes that can be used by patients without the aid of a trained technician. The project includes the physical design of the spirometer, software development, and designing a universal interface. We envision a first generation device that connects to a computer via a USB port and guides and coaches patients through the testing using digital audiovisual clips. As the procedures are performed, a combination of client and server software will graphically display flow and volume data, monitor and evaluate the quality of the maneuver, and instruct the subject when their performance needs to be corrected. The software should also carry out some rudimentary analysis and interpretation using algorithms that are freely available from the American Thoracic Society. Overall, we hope to develop a tool that would be widely affordable and would standardize pulmonary function measurements by delivering the same instruction and coaching across sites for the first time. Last Week’s Goals • Get keycard access to 2029 ECB • Continue developing PDS, send preliminary version to client and Amit • Establish website • Perform/review BME 310 Spirometry lab • Begin to break project into components for division of tasks • Target areas to modify spirometers for cost efficiencyAccomplishments • Got keycard access to 2029 ECB • Met with Amit, John and David to discuss design components • Posted on openspirometry.net forum to get design feedback • Ordered sample pressure sensor • Attended Engineering World Health meeting pertaining to medical conditions in emerging countries • Assigned specific research topics to individual team members. This Week’s Goals • Create various designs and analyze them with a design matrix • Begin SolidWorks modeling • Write audio/visual training and coaching requirements, submit to David and media coordinator • Experiment with incorporating the pressure sensor in basic circuits. Difficulties • The countries we are interested in using our device do not possess the power infrastructure we had imagined. Therefore, our design will need to be altered, specifically at the hub.
