Adviser: Dr Franz BaudenbacherSponsor: Dr John EnderleTeam Members:Nor Haslin Mohd AliMus’ab ShaharomYazmin Zakaria
Project background
National Student Design Competition Project Choice: Accessible Blood Glucose
Monitor Funding: $ 2000 Advisor: Professor Baudenbacher
Our Clients..
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 (400lbs).
Arnold - has Parkinson’s disease, and experiences slight to moderate tremors. He lives alone.
Project Goal
The blood glucose monitor must 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
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
Use existing product - test strip based monitor
Build voice box for audio output
Build finger placing guide for client with tremor
Output : Blood glucose measurement High/Low status - alarm Average measurement
