Semester 2- Week 12 Kierstin

 Lab testing: 

This week we tested our manufactured valve to see the opening pressures for each ahmed valve in the system. We labeled the valves as follows: 1(left), 2(right), 3(middle) 

We used a water column at different heights to test at what pressure mmHg the valve would open and allow flow. The results and lab setup are shown below. 

We manufactured another valve that we will be surgically implanting into the pig head when we do that surgery. The valve has the same dimensions as the baerveldt valve, but it is not a functioning valve. 

Capstone Poster:

A lot of this week was spent working on the poster. I looked over Dr. Gordon's suggestions and made a mock-up of what I was thinking for a timeline of our design. I discussed it with Brinkley to make sure it accurately represented what we thought our product would do over time. 

I created these images of the eyes with our specific valve, which took a lot of time because I’m not great at photoshopping things and I had to just use PowerPoint and cropping tools to create the images. It also took a long time to format the timeline so that it would fit on our poster in a way that was easy to read. The table below is the final product that I put on the poster. 


I made the left side of the poster, but when looking at the right side I realized there was some discrepancy in the wording that did not match our project. So I reworded the writing sections so they were consistent with what we did, and the actual surgical procedures for glaucoma surgeries. I also created the chart shown below that represents the testing we did. It shows the opening pressures of the three valves. The 3rd valve did not open, but anything over 40 mmHg is not really anatomically possible. These pressures are higher than what we would want our valve to open at. This could be because the valves we got were defective. 


It took a lot of time to rearrange this side of the poster to fit both the pictures and the chart. The below image is the final arrangement for our poster for the right side with the picture and chart.

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
