Portable Lancing Device
Paul Kudrna and Gil Cavada
Portable medical device used by diabetics to test their blood sugar levels throughout the day. This model is unique because the design incorporates a magnet instead of a spring mechanism, that propels the actual lancing device in to the skin.
Quantified dollar savings because Pro/ENGINEER was used is as follows: 1)Pro/SURFACE 2 weeks to model, check fit and visualize, savings estimate of 2 weeks using other tools. 2)Pro/MECHANICA done in house, savings estimate of 4 weeks and $5000 in trial prototyping. 3)Pro/MoldAdvisor 2 days to simulate 9 parts being molded, savings estimate of 3 weeks of eliminated tooling tweaks and $10000. 4)Pro/Man done in house 2 weeks total for all 9 molded parts, savings estimate of 2 weeks using the next best available tool. 5)Pro/Verify 5 days to scan and verify all 9 parts, savings estimate 2 weeks faster than traditional inspection, saved $8000 over traditional CMM inspection, eliminated need to create dimensioned drawings - 1week, eliminated multiple passes due to incomplete CMM inspections – 2 weeks. Total Saving: Time – 13 weeks at $5000/week typical engineering cost = $65,000, direct cost $23,000. Total estimated savings = $88,000
The great reduction in the pain produced by the lancer is the notable innovation of the design, making it a little easier for diabetics to cope with their disease. Diabetes is one of the fastest growing diseases in America with 6.3% of all Americans being diagnosed and an estimated additional 4% that are undiagnosed. It is estimated that as the baby-boomers come into retirement and into the peak years for acquiring Type 2 diabetes up to 15% of Americans may be diagnosed with this disease. Additionally, more children are being diagnosed every day with Type 1 diabetes and current lancing devices tend to be very intimidating, non child friendly, painful and cumbersome to use. This design is ergonomic, child friendly and easy for the elderly to use. It also causes, much less pain, than lancers on the market today.
