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

• • Design presentation done.

  • Began outline and completed Week 2 sections of report. 

  • Reviewed steps for gelatin + glycerin casting and ordered parts.

  • Pumps for blood pressure delivery will be ordered this week 

Accomplishments from Previous Week

• • Design presentation is complete.

  • Established a direction for manufacturing skinfold moving forward.

  • First draft of selected sections in report is complete.

  • CAD of mold. 

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

• • CNC the 2 part skinfold cast

  • Cast gelatin and glycerin mixture to develop skinfold.

  • 3D print mold.

  • Order 2-3 (depending on their price) pumps for investigation (Guinevere)

  • Find appropriate method of connecting pumps to vasculature tubing (Yichen)

  • Source & order an artificial blood for testing the pumps (Samantha)

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

• • Meeting with sponsor last Monday (Dr. Ryan) (notes can be found in the last update). 

    • Monday’s holiday delayed this week’s sponsor meeting

  • Actions taken:

    • Bought gelatin and glycerin to perform the casting. 

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

• • Comments on design presentation  

Risks and Areas of Concern

• • Scheduling consistent meeting time with sponsor.

  • The skinfold should not tear, should have high tensile strength

  • Casting holes in the skinfold for vasculature

  • Gelatin mixture should not press down on the silicone tubes while casting

  • Finding proper pumps to create the pressures in vasculature

  • Aiming for 2 different pressures for the vein & artery

Schedule

• • Next week:

    • Cast

    • Meet with Dr. Suttner 

    • Plan user testing with clinicians

    • Continue writing report
