Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Made key design decision of using Silicone tubing for vein. 

  • Preliminary research results from the task into two “mini” teams to focus on 1) pressure delivery system and 2) skin/flesh manufacturing. 

Accomplishments from Previous Week

• • Preliminary research results on the overview of casting/moulding.

  • CAD of mould for muscle system. 

  • Preliminary research results on pressure system. 

  • Met with Dr. Ryan to confirm our methods for casting. 

Goals for Next Week (list names after each item). Use specific and measurable objectives.

For Rahaf and Reem:

• • Still need to get George to send me his experimental process (Rahaf, send request again). 

  • Visit Machine shop to confirm the creation of the mould.

  • Finalize material selection and order parts.

For Cecily, Samantha, and Guinevere:

• • Research over different types of pumps and determine which are potential options. 

  • Start ordering pumps online. 

  • Design a system with [two] blood pressures for vein and artery.

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • Confirmed approach with Dr. Ryan → attach holes in the design of the mould to release air. 

  • Dr. Ryan encouraged us to think about the end-user and constantly think about “how many times are they planning on doing ECMO per year? Would silicone be worth it given cost constraints?” 

  • Helped with research keywords such as “ballistic gelatin”; provide practical advice on making gelatin models (spray oil before casting/ consider materials shrinking/ store in fridge to keep moisturized)

  • Check Reddit DIY community for help on casting.

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

Comments:

• • Reach out to sponsor and schedule meeting on weekly bases. 

  • Think of latex-dipping for vein. 

  • Add comparison table to show why we chose silicone for veins.

Actions:

• • Had a sponsor meeting on Monday morning to discuss moulding and casting methods.

  • Justified why using silicone for veins in the design proposal presentation.

Risks and Areas of Concern

• • Moulding and casting seems to be an experimental and “trial and error” approach.

Schedule

• • Next week:

    • Order materials 

    • Meet with machine shop
