To continue the development of a prosthetic deodorizer and disinfectant by researching the effect of UV-irradiation induced silicone degradation, the success of disinfectanting a silicone surface with a certain exposure and wattage, and the effect of titanium dioxide in terms of deodorizing the liner.
This week our team is defining the methodologies in which for testing the prosthetic liners in order to meet the objectives of our client. These tests include a odor eliminating test; studying the application of titanium dioxide and its effect on odor, the germicidal test; understanding the exposure limits and proper wattage of UV-radiation bulbs in terms of killing bacteria on the liner, and the degradation test; understanding the effect of UV-irradiation on silicone liner materials. A descriptive lay-out of each of these tests will be placed in our mid-semester presentation this Friday along with many other details about the project as a whole that we are currently work on.
| Week | Reporting Period Beginning | Activities |
|---|---|---|
| 1 | September 7 | Presented with new project; started researching the objectives |
| 2 | September 14 | Met with client to go over specifics and questions, PDS formation, |
| 3 | September 21 | Priliminary testing of the degradation of silicone to UV-irradiation on worn liner, ordered two new prosthethic liners for future testing |
| 4 | September 28 | Continuation of priliminary testing; |
| 5 | October 5 | Received new liners, researched and studied material about wattage and radiation |
| 6 | October 12 | Defining methodologies for the odor, degradation, and germical testing, mid-semester presentation preparation |
| 7 | October 19 | Mid-semester report prepartion, creating test protocols to start testing within the next week |
| 8 | October 26 | Looking into germ test setup and location and resources needed to perform it. Rough sketch of degradation set-up completed; needs to be built |
| 9 | November 2 | Building of degradation test setup; need to acquire black material for covering, socket connector for E15 bulb, and temperature sensors. Confirming germ test location and delivery. Will begin cutting liners for testing. |
| 10 | November 9 | Beginning bacteria testing-cultured bacteria, process with continue until Week 14. Setting up deformation box; order E14 socket base and thermistors for temperature monitoring, will begin to test liner pieces after all parts arrive. |
| 11 | November 16 | Germicidal testing continues-cultured bacteria on liners before Thanksgiving break |
| 12 | November 23 | Degradation testing will begin this week as well as disinfecting the bacteria on the liners and reculturing them. Titanium dioxide purchased and arrived. |
| 13 | November 30 | Degradation exposure complete, tensile testing and analysis to begin, culture comparison to begin, odor test underway |
| 14 | December 7 | Final Presentation |
