Week 11 - Brinkley Brooks

 This week was completing our prototype and testing. We have a general design right now of an epoxy oval with 4 tubes. One tube is connected to the syringe and the other three contain resistors of varying levels. We did a lot of work on trying to vary the resistance this week. The design that we are going to go with is resistors of the same diameter but different length. In our larger prototype, we have different length epoxy cylinders in the tubing. We made those cylinders by cutting open a silicone tube and filling it with epoxy. Once it was dried, we cut it out of the tube and cut it into three different lengths. For the smallest tubing, we are using different length of polyester sutures as our resistors. For both scenarios, this ensures that the shape of every resistors is the same. 


Here are the new square molds Kierstin created and I filled. These are much smoother than the previous ones, which will allow easier drilling, and a cleaner look overall.

Video of Kierstin and I testing the triangle resistors I made. They worked, but were not the same shape, so hard to tell if the resistance varied because of the shape or the size.

  MEDIUM
  SMALLEST







The sutures that we used as the resistance for tiny tubing. We varied the length three times to create different resistance levels. 

Video of the epoxy cylinders as the resistors. They have different lengths but same diameter, so they create different resistance. 

New filled epoxy boats. 



Meeting with Kierstin Notes: 
  • Discussed Email and Team dynamics 
  • Thought of enclosed silicone system methods
    • Rolled tape in the boats and then pull out tape to make holes.
      • Did this on 11/18 and it works, will use for future design potentially
Last Lab time - using softer silicone in the molds

Week #3 - Brinkley Brooks

This week consisted of a lot of brainstorming, planning, and researching. I also contacted the client multiple times to figure out a shake down test we will be doing soon, and to update our deliverable 1 and 3. I also worked on making tasks and timeline for deliverable 2.  Brainstorm:  Decided on a remolded Ahmed valve with rubber material resistance (elastic) with a possible dissolving factor. This will be a combination of strategy 1 and 3.  Elastic Resistance  - most similar to Ahmed valve, but will change the resistance post fibrosis to have a better success rate 2. Magnetic Resistance  - uses a magnet to open and close a valve to vary the flow 3. Dissolvable Resistance  - Using a material that over time dissolves, so that once fibrosis occurs, the part of the valve that doesn't need to be there will be gone Client Meeting Notes:   Here are the notes I took during the client meeting. We discussed the schematic that we will be following for our shakedown, and the principles behin

Semester 2 Week 12 - Brinkley

 This week in class we discussed with Gordon what needed to be changed and updated on the poster. The notes he had for us were to better explain the reasoning for the three valves and what issues they solve. We updated the poster with these images and explanations.  During lab time, data was collected on our prototype. We were able to find when the 3 valves open and at what pressures. Valve 3 seems to have a defect because even at extremely high pressures it does not open. This is not a fault in our design, but is caused by using faulty Ahmed valves. Here is the data that we collected from class.  Kierstin and I had a meeting on what needed to get changed in the poster, and here are the meeting notes:  After the poster was finished, I began working on our final presentation. I looked over the requirements and began creating an outline for the flow of the presentation. I also worked on finishing my research paper. Because some of my sources were deleted that I researched, I had to go ba

Semester 2 - Week 13 Kierstin

  Lab time:  This week we did our pig head surgery simulation for our verification testing on surgical procedures, and if the device is mobile or not.  Our pig arrived in a box full of packing peanuts. It was very heavy and surprisingly very clean.  We unpackaged the head and placed it in our pre-prepared surgical location. We used trays and covered the table with sticky paper so it would be easy to clean, and nothing would get pig blood on it if it wasn't supposed to.  We started our surgery by suturing the eye so it looked away and giving us a clear spot to cut for the valve insertion. We put the suture through the sclera and then tied it around his ear so it wouldn't move during the surgical procedure.  We then cut the conjunctiva and created a pocket for the valve. I did the main cutting, Brinkley took pictures, and Alex helped give tools and be an extra hand in the surgery. We used scissors to cut it, and then players to create the pocket.  We inserted the valve into the p
