Capstone Week 8

 Week 8: 


Looked up parts on McMaster for fluid flow in parallel shakedown, and sent needed parts to Alex. 

When we went to the lab to fix the flow sensor, some bubbles got in our system, and our Ahmed Valve broke when we were trying to fix this. We now have to wait for our apple sauce pouch to simulate the pressure from fibrosis.

 




Each component had to be separately sketched, and then I had to make it a tube by extruding and cutting, or using the sweep boss base. I also made the material silicone to see how the tubes are connected and how the fluid can flow. I think that 3d printing might help us learn how to put the parts together and manufacture our valves by practicing gluing and sewing silicone covers to this component. 

Created a valve to connect our ½ in tube to our ⅛ in for pressure testing in our shakedown testing.


I had to figure out how to scale the part by ½ because changing the drawing messed up later sections of the part so I couldn’t go with that method. 

My part got denied because the diameter was too small. 


Lab Testing: 



Redrew plugs sizes .3-.45 in increments of .05. Also redrew the connector valve because it got denied by the print lab. (Shown above) I submitted all the parts to be able to do my shakedown. I will just have to drill a hole in the connector to be able to read the opening pressures. 

 




I went back into the lab to redo the Ahmed in the pouch and I got it to the same point as before, but I forgot to purge the second half of the system I knocked the needle out of the valve. I am going to go back in and try for a third time either tonight or Wednesday.

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...
