Background/Motivation
Many diabetes patients use syringes on a daily basis to inject insulin
For diabetes patients with vision problems and neuromuscular disorders It becomes difficult to
read the volume of fluid on the syringe set the syringe’s plunger to the correct dosage Draw/inject the plunger at a steady rate (preventing air
bubbles)
Current products
Insulin pumps (Minimed) [1] Costly (~$5,000) Must be worn constantly and
programmed Autoject2®-Owen Mumford [2]
Assists in injecting, not dosing
Nordisk Novopen® [3] Requires some dexterity to
set the dosage correctly Uses only one type of insulin

Market of Personal Care Products
“The development of in-home medical technologies, substantial cost savings, and patients’ preference for care in the home have helped make this once small segment of the industry into one of the fastest growing in the U.S. economy.”
Career Guide to Industries, Bureau of Labor Statistics [6]
Market: >65 years In 2002, 12.4% of population was >65 [7]
12.4% of the population accounts for 40% of the annual healthcare costs [7]
By 2020, this age group is expected to climb to 17% of the population [8]
Diabetes and obesity
on the rise [9]

Diabetes:18.4% ofthose >65 [11]
Over 65:12.4% ofUS pop.[7]
Marketing towards Doctors & Insurance Companies Doctors are a major influence on patients’ purchase
of products and services Increases dosing accuracy Strong alternative to insulin pumps Easy-to-use keypad and easy-to-see digital display
Insurance companies pay for >80% of products [13] Cheaper than insulin pumps Novopens, >$80, need refills and are more costly than
The EasyMeasure Syringe Savings over the long term
Introducing our Product to the Market
FDA: Class I device [14]Fewer restrictions than Class II/III devicesMay be approved more quickly
Present poster at a conference Interface with doctors and professionals and
compare device to existing products American Association of Diabetes Educators American Diabetes Association
Manufacture
Easy to manufactureCustom Parts
Casing via injection molding Circuit
All other parts are available for purchase Potential manufacturability conflict
There are motors small enough for this application
However, smaller motors may have too little torque
Conclusions
Beneficial to diabetes patients, especially with poor eyesight and/or poor motor skills
Affordable and advantageous alternative to current products
Competitive in the market Attractive to doctors, patients, and
insurance companies
