Project background n n National Student Design Competition Project Choice: Accessible Blood Glucose Monitor Funding: $ 2000 Advisor: Professor Baudenbacher

Our Clients. . n n Dave – 22, has limited use of his right arm and leg. Wanda – 12, has low vision, encouraged to start administering insulin to herself Lloyd – 80, has some hearing loss and is very overweight (400 lbs). Arnold - has Parkinson’s disease, and experiences slight to moderate tremors. He lives alone.

Project Goal n The blood glucose monitor must q q q communicate effectively visual display and voice output. calibration and expiration dates of test strips ease of learning, storage of all components, cleaning and maintenance. affordable and portable

Problem n Existing blood glucose monitors in the market do not satisfy the needs of all our clients. Also, some of them are quite expensive.

Design Considerations n n Use existing product - test strip based monitor Build voice box for audio output Build finger placing guide for client with tremor Output : q q q Blood glucose measurement High/Low status - alarm Average measurement
