156A Finals Week

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

• • Risk Reduction Presentation finished for final

Accomplishments from Previous Week

• • First CAD model of ramp made

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

• • Make more progress on designs for both ramp and blade - Everyone

  • Review results of risk reduction with sponsor

  • Move onto individual analysis components (3/25)

  • Take the results of risk reduction and apply them to further iterations of the ramp (4/3)

  • Perform similar risk reduction for an intubation tube/blade design (4/3)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Meeting on March 22

    • Ramp

      • talked about the concepts behind zero gravity chairs, use weight of head in levering

      • hinge could help avoid the quick, abrupt moves

      • talked about the possibility of using a dial for an infant, lever for an adult (ratchet back and forth)

      • Discussed the possibility of having an electronic readout to measure the angle

    • Blade

      • make a slightly wider blade at the end like a duck bill 

      • possibly redesign the whole blade instead of making an attachment

      • can make centerpiece wider to flatten out tongue some more for bigger patients, like a tongue depressor

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Dr. Gravish: If we continue with the linear slider idea as shown in the risk reduction presentation, we need to find a way to make it much smoother

  • consider two degrees of freedom in ramp adjusting mechanism

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • feedback from presentation: 

    • liked physical demonstration of intubation tube in laryngoscope

    • Liked videos of intubation process to explain the project

    • great speaking and explanation

    • jamming might be a problem

    • could have explained more about other designs considered

Risks and Areas of Concern

• • jamming slider is too rough, so need an alternate method of changing angle
