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 pocket and slid it as far back as we could. And then sutured it into place with just one suture, when normally there are two. 

We then used the 23G needle to create a track and inserted the tube into the anterior chamber. This was the most difficult part. We got the tube in the track, but could not push it as far as we wanted into the anterior chamber. 
The image below is the pig with the valve fully implanted. This surgery was not more complex, and the device is mobile because it can fit comfortably in the pig's eye. 

This surgery verified that our product was not more complicated than other glaucoma surgeries today. 


After the pig surgery, we did a deep clean of everything and disposed of the pig head. We cleaned up our station and cupboard so it is cleared for next year's team. 

Final Preparations: 
The rest of this week's work was done on PowerPoint. I inserted a lot of pictures and made some flow charts for the benchtop testing. I also inserted the images from SolidWorks. Many of these images had to be edited to fit the theme of the presentation. I also made slides that describe the steps of the glaucoma surgery that we simulated with the pig eyes and the pig head. I also worked to create a template to print the slides for the final presentation. 

I also did my team evaluations. I think that everyone did a really great job this semester.

Week #3 - Brinkley Brooks

Image
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

Image
 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
