         Problem Statement
 Client: Michael J. MacDonald, MD
 Diabetes Type I
 Protein Drug Delivery System
  – Inexpensive
  – Constant Injection Rate
  – Disposable
       Background Information


 Diabetes Type I
  – Immune system
  – Glucose level in the blood
  – Juvenile onset diabetes
  – Injections/Pumps
       Background Information

 Insulin
   – Protein-based drug
   – Onset, peaktime, duration
   – 5 to 10 units/day
       Unit = 0.01 mL
 Protein Drugs
   – Skin, ingestion, injection
 Injection sites
 Current Devices: Insulin Pumps

 Insulin syringe (3)
 Battery operated pump (2)
   – Computer controlled
 Infusion set (1)
   – Tube
   – Needle (soft or metal)
 Very expensive ($5,000 –
  $7,500)
Research Competition

           Professor Beebe
           Hydrogels
            – Stimuli cause
              expansion in gel
            – Currently toxic
            – Non-linear expansion
            – Wound-dressings
            – Easy to mold
         Suggested Materials
 Metering Valves
  – Controls flow
  – Chromatography
 NanoMuscles
  – Contract like human
    muscle
  – Rotational or linear motion
