Week 4 - Brinkley

 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)
  1. Silicone
  2. Silk
  3. Device enclosed in silicone

MOD #2 - Dimensions

Top 3: (in no order)
  1. Multiple Tubes/ Vary the lengths & spacing
  2. Varied thickness of resistors
  3. Needs to fit inside of eye

MOD #3 - Varied Resistance Valves

Top 3: (in no order)
  1. Silicone sandwich/ Like Ahmed
  2. Dissolving poppet valve
  3. 2 Valves that start working at different times



MOD #4 - Durability/Shelf Life

Top 3: (in no order)
  1. Packaging that preserves
  2. Manufactured with good materials 
  3. FDA Testing 



MOD #5 - Implantation

Top 3: (in no order)
  1. Similar to Ahmed (with a pocket, maybe cut with laser?)
  2. Extra surgical implantation device 
  3. Tissue to cover implant 



MOD #6 - Fluid Distribution 

Top 3: (in no order)
  1. Multiple tubes with varied valves and end locations 
  2. Holes on plate instead of tube 
  3. Shunt with valve



MOD Tops: 

1. Dimensions: Needs to fit in eye & multiple tubes 
2. Materials: Silicone & a potential silk component 
3. Varied Resistors/ Valves: Sandwich & dissolving valve after 6 weeks
4. Durability/ Shelf-life: Durable packaging, materials, and manufacturing 
5. Implantation: Similar to Ahmed, potential surgical device 
6. Fluid Distribution: Multiple tubes with possible tools 



Lab Set-Up:

Constructed with lab flow set up to do an experiment with the current Ahmed valve to gain better insight on how/what we should change to get varied resistance. Half of the lab is set up, and we can move forward once we have pressure sensors, which our client is looking into.

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...
