This week was shakedowns, bench top testing, and more shakedown designs. Our materials all hadn't come for some of our shakedowns, so we focused on our bench top testing to begin, then we designed more shakedowns. BenchTop Testing Our bench top testing is done on the Ahmed valve to see how it preforms when we can control the flow, resistance, and pressure. We had to create an encasing for the Ahmed to simulate fibrosis and add it to our bench test. Here are a few pictures of Kierstin and I working on the setup, and get the flow sensor to work in our system. Fady is working on the pressure sensors, so we will be able to execute this bench top testing on Wednesday during class time. This set up took so long because we had to find supplies in Dr. Rickard's lab that we could experiment with and see if they would fit in our set up. ShakeDown #1 The first shakedown we were able to do with the supplies we had was seeing how water flowed through a tube when it was partially bl...
The main focus of this week was brainstorming modules of our design. We first did a brainstorm of all the modules we could think of, and then chose the top 6 from that paper. The modules that we decided on were the material that will be used, the dimension, varied resistance/valves, durability/shelf life, implantation, and fluid distribution. Another large task that I participated in this week was setting up a lab, which will be shown later in this post. We also met with our client who helped us come up with the design for the lab. Client Meeting Notes: Brainstorm Modules: MOD #1 - Materials Top 3: (in no order) Silicone Silk Device enclosed in silicone MOD #2 - Dimensions Top 3: (in no order) Multiple Tubes/ Vary the lengths & spacing Varied thickness of resistors Needs to fit inside of eye MOD #3 - Varied Resistance Valves Top 3: (in no order) Silicone sandwich/ Like Ahmed Dissolving poppet valve 2 Valves that start working at different times MO...
