Update 4/10/2020
Apr. 11, 2020—This week, we made our poster for Virtual Senior Design Day on 4/20 and presented it to Dr. Walker. Now, we will add market analysis to our poster, add figure captions, and practice our 5 min presentation. Below is a screen capture of our smooth draft poster.
Update on 3/27/20
Mar. 27, 2020—This week, due to the transition to working virtually, we focused on the tasks given by our instructor to strengthen and give fullness to the model we created while on campus. Predictive Failure Model: We predicted the way in which the model we had created might encounter issues when implemented in a clinical setting....
Weeks of March 9 – 23
Mar. 22, 2020—This update will serve as our update for the past 2 weeks, since classes were cancelled the week of March 9. We apologize for the delay in posting this update. We were notified on March 11 that we had to leave campus on March 15, so we were scrambling to say goodbye to all of...
Update #8: Week of Feb 24
Feb. 28, 2020—This week, we took a step back and focused on researching current solutions and brainstorming new approaches to various parts of our project. Below is a task list of how we divided up the research. Compression: We contacted Hanger Prosthetics to ask for soft, medium, and hard grade memory foam. We plan to use this...
Update #7 – Week of February 17
Feb. 21, 2020—This week we made good progress in all three characteristics we desire for our device, but especially so in our preliminary testing for an optimal method of compression application. We met with Dr. Curci and Nathan, a representative from Hanger prosthetics, who supplied us with more insight on the directions we are taking. Compression:...
Update #6: Week of February 10
Feb. 14, 2020—This week, we primarily worked on our pump and air bladder compression system, soft potentiometer limb volume measurements, and building a holder for our pulse oximeter. We also brainstormed how to integrate all our components together by making a control diagram and beginning to write pseudo Arduino code. Compression: This week, we interfaced servo motors...
Update #5: Week of February 3
Feb. 7, 2020—This week, we made air bladders for our first prototype of the automatic compression sleeve, attained SpO2 readings from our pulse oximeter, attempted to solder lead wires to knotted ends of our soft potentiometers, and continued to work on the evaluation board for bioimpedance measurements. Compression: With regard to compression, this past week we searched for...
Update #4: Week of January 27th
Jan. 26, 2020—This week, we began delving more thoroughly into each category of our design project. We also placed more orders for parts that we needed. Edema Prevention: This week we constructed our first prototype of the automatic compression sleeve. Our first prototype of the compression sleeve consists of an automatic blood pressure cuff sewn together with a homemade wrap fitted...
Update #3
Jan. 24, 2020—This week, we began working with the parts that we ordered. Below we will discuss our progress in each of the 3 aspects of our project. Edema Prevention We bought stretchy nylon fabric to use on the shrinker that Hanger Clinic gave us. This weekend, we plan to sew the fabric on the shrinker as a...
Update #2
Jan. 13, 2020—Order for Spring Prototyping We have successfully research and complied a list of items to be ordered for our project. These will cover the main desired functions of the sleeve: to prevent edema and monitor skin perfusion actively. Edema Prevention To actively attempt to prevent edema post operation, we plan to implement mechanically inflatable...
