Low-Cost Prosthetic Progress Update
April 20, 2006 Jina Kim Forrest Liau David Lin Teresa Wang
2
Overview Process Materials Prototype Wax & Plaster Latex & Silicone
Prosthetic suspension Measure of success
3
Process
4
Problems with Wax & Plaster
Deformations After hand extraction Before pouring plaster Plaster Recipe Compatibility with wax
5
Latex Glove TAP Plastics Brushable Latex Chemistry
Polymerized monomers (i.e. isoprene) Sulfur/vulcanization
6
Silicone Underlayer Smooth-On Mold Max 15T, tin-based
Cures at room temperature overnight Post-curing at 125 °F for 4-5 hrs Chemistry Base = organosiloxanes + silica Catalyst = organotin
7
Suspension Method Advantages Disadvantages Negligible bulging
Less deformation Disadvantages Lack of control Glove creases
8
“Success” Latex glove Silicone underlayer Fits well over other hand
Slight difference in finger length Silicone underlayer Roughly correct shape
9
Glove Materials Latex rubber Brushable silicone Surface adherence High
Minimal Process 8-10 layers 1-2 layers Cure time Overnight 6 hours
10
Underlayer Materials Tin-based silicone Platinum-based silicone
Compatibility Latex Silicone Durability 3-5 years 10 years Cure time 24 hours 5 hours
11
Schedule TODAY
12
Future Direction Platinum-based silicone prosthetic
More in-depth cost analysis Optimize underlayer process Develop how-to-make manual
