Capstone Week 5

 Week 5: 

Lecture:

Dr. Gordon talked about budgeting and the importance of it. He talked about having an emergency fund for when unexpected expenses arise. 

Meeting with Client:
Our Team also met with Dr. Rickard, the notes from the meeting are below.
-During this meeting we went to the Lab with Dr. Rickard to go over essential supplies for benchtop testing and to see where we will be able to conduct our work. 
-Our team then looked up some supplies that we are looking into ordering for our testing. 
- The pouches would be a shake-down for the tubing part I drew up last week. 
Del 4: 
I was assigned to Del 4.3 so I updated the Jira as such. 
Research and Design Ideation: 
- In my research and brainstorming I used Youtube and all my previous background research to come up with the designs below
- This design included brainstorming for shakedowns
-The rest of the team also brainstormed design ideas and shakedowns shown below 





Work for next week: 
-I updated our Jira work for next week
Article from Client: 
-Dr. Rickard sent "Computational and Experimental Analysis of an In Vitro Microfluidic Experimental Setup on Testing Molteno, Ahmed Valve, and Ex-Press Implants and Their Critical Comparisons" for us to read

Key Ideas were: 

  • a new glaucoma drainage device should be equipped with a slimmer but larger end plate and a valve mechanism similar to Ahmed Valve in the perspective of intraocular pressure drop performance. (This means that my idea could be really good I think) 

  • The tube shunts and discharges the flow resulting from pressure differences on each side of the plate. Despite its simple tube and plate configuration advantage, Molteno GDD has substantial disadvantages such as uncontrolled flow mechanism, occasional poor reduction in IOP when in charge, and frequent cases of hypotony
  • To prevent postoperative hypotony, valved GDDs such as Krupin slit valve and Ahmed Valve or Ahmed Glaucoma Valve (AGV) were developed.
  • Therefore, a more effective in vitro setup for testing GDDs is a challenge to focus on. This setup should ensure the testing of any GDD in a medium that is similar to the eye in vivo.
  • In our proposed setup, fluid flow is driven by gas pressure produced by the microfluidic flow control unit in Figure 1, which sends compressed air into reservoirs so that flow initiates.


  • Molteno does not occupy a passive valve to inhibit the reverse flow as in AGV and does not envelope small flow area as in Ex-Press GDD

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...
