Semester 2 Week 4 - Brinkley

 New molds were made based off of Kierstin's newest 3D print. I poured in the silicone to have multiple models to test on. 



The voltage values were found at different heights and then the pressure values were calculated from that.. Kierstin and I spent time in the lab doing this to create our voltage to pressure conversion equation. This was done in a google sheet. 

After we finished in the lab, I went back into the google sheet to organize it better and make readable charts. This chart shows the pressure values of different diameter sized resistors at different lengths. 





Because we had found the above pressures, I was able to input them into different formulas from del. 5. These are shown below. 


Kierstin and I went back into the lab to manufacture 2 prototype valves. We sealed them with the soft silicone to seal up the holes where the tubes were inserted. I went back into the lab later in the week after they dried, and one of the valves was sealed properly in 3 tube insertions, but the 4th tube had fallen out leaving a whole. The 2nd prototype got siliconed shut in all of the tubes, allowing no flow.

Kierstin created a new mold, so I went into the lab to pour more. I have popped them out too, so they are ready for class tomorrow. 

Lastly, I spent tine researching how to do the testing/verification for del. 7. Here is some of the research I found so far.

Week 7 - Brinkley

 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...

Week 9 - Brinkley

 This week was a lot of testing and research. I am still working on the dissolving component and figure out that data, which will make more sense with time hopefully. When we were in the capstone block, we did a couple of shakedowns, we did a brief resistor in parallel test that worked great, Fady set up the sensors, and we modified parts we already had to make them work for shakedowns.  The research I did this week was about materials. I researched silicone sheets, silicone molding, glue, and sutures. For each category I found biocompatible and regular options. The regular options are much cheaper and easier to get.  Here are the links to the products I found:  Research Mold and Curing Silicone:  Biocompatible: https://www.elkem.com/silicones/offer/healthcare/medical-grade/liquid-silicone-rubber/ I would suggest soft or mid durometer because it would be less preventative of the tube expanding. Less resistance. Another option is:  https://products-silicones...
