156B Week 2

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

• • Intubation ramp scissor lift, tentative ramp assembly, and laryngoscope blade were modeled in SolidWorks

  • Method for measuring ramp angle has been chosen and component to purchase has been chosen

Accomplishments from Previous Week

• • Individual Component Analysis conducted to determine designs for laryngoscope guidance component, angle measurement display, and intubation ramp height and angle controlling component

  • Created list of parts needed to purchase

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

• • Determine material needed for ramp to comfortably support infant - Emeline

    • Design an ideal shape of material to contour to infant's head and body to prevent slipping

  • Further develop optimal laryngoscope blade design and print - Brendon

  • Determine materials for base of ramp and placement/housing for goniometer - Wendy

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

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

    In-Person Team Meeting (4/5/17)

• • Typos on previous progress report - Dr. T

    • Further proofreading of Week 1 progress report resolved any issues

  • Question regarding inquiry about injection molding - Dr. T

    • Suggested Proto Mold if needed but it costs a couple thousand dollars

      • If we have a solid design, we can send it to Proto Mold to get a quote if interested in production

    • Pedro recommended using the vacuum former in the Envision Studio if needed

  • Questioned why we were considering a digital readout of the angle since it creates more complexity - Dr. T, Professor Silberman, Pedro

    • If we need it, need to explain and prove why it is worth the effort

    • Gave us questions to consider: What are errors in analog reading? Are small angles a significant problem for this case?

    • Suggested using a three-axis accelerometer to measure the angle

  • Professor Silberman suggested speaking to Abbott Vascular to ask about their method of guiding and navigating tubes within the body

    • This can help us with further designs for controlling the intubation tube

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

• • NA

Risks and Areas of Concern

• • Laryngoscope: concerns with extra components attached to the blade in a small infant's mouth

  • Decreased range of visuals with extra blade guidance

  • Aiming to make the ramp mostly disposable but there are concerns with which parts should and should not be made disposable

  • Eventually will need to test the ramp to determine optimal angles for range of infant sizes, but cannot test this on live infants

Resources or Information Required but not Available

• • NA

Schedule

• • Purchase baseline goniometer (4/12/17)

  • Upload drafts of background, review of existing solutions, statement of requirements, deliverables, title page, and appendix with individual component reports (4/14/17)

Budget (list amount spent and amount remaining)

• • Amount Spent: $0

  • Amount Remaining: $1500

Progress on Report and Webpage

• • Report outline started

  • Webpage updated on 4/11/2017
