156A Finals Week

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

• • Risk Reduction Presentation

  • Storming process for the needle insertion device

  • Activated Onshape accounts for future CAD drawings

Accomplishments from Previous Week

• • Preparing Risk Reduction Presentation

  • Preparing  ideas/solutions for the Individual Risk Reduction Analysis 

  • Created a concept (drawings) for the design of the deployment device

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

• • Risk Reduction Process

  • Learning Onshape/Solidworks for CAD 

  • Research and complete Individual Risk Reduction analysis

  • Learn more about the results obtained by Capillary Bio's work for determining the insertion forces necessary to deploy the needle through the skin and possibly apply it to our own analysis.

  • Model our prototype in Onshape/Solidworks

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

• • Feedback about the presentation slide (03/21/2017, Teleconference)

    • Milestone slides--pass time for iteration and the rest of the time planned out for the quarter, detail it more

    • Include end point (end of quarter)

  • Shared students' concern about lack of knowledge in designing medical device (03/21/2017, Teleconference)

    • approved for designing 3-to-1 scale

  • Andres will send 3D model of needle and we can design our own needle tip (03/21/2017, Teleconference)

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

• • Have we visually conducted an insertion trial? (03/21/2017, Presentation)

    • Answered: Not with the actual prototype as we haven't made the prototype yet. However, we can conduct it with silicon kit or pork butt with skin

  • What is our design idea for the pump? (03/21/2017, Presentation)

    • Answered: It is not our objective to work on the pump, our main goal is to design an inserting device and housing case for theCapillary Infusion Set, 2017 concept  

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

• • Isn't helicon shape insertion hurt more? (03/21/2017, Presentation)

    • Answered: The gauge of the stylet what we will use is small enough to minimize the pain

  • How we can understand the depth of insertion? (03/21/2017, Presentation)

    • Answered: There will be three different setpoints for insertion

Risks and Areas of Concern

• • What will Capillary think of our prototype idea?

  • Will Capillary Bio's results regarding the insertion forces necessary to deploy the needle through the skin help with our energy analysis for rotational insertion?

    • Will find out more during Spring quarter Week 1 teleconference with Capillary

Resources or Information Required but not Available

• • Capillary Bio's results on their research for determining the insertion forces necessary for the needle to penetrate the skin

Schedule

• • Describe upcoming milestone

    • 04/04/2017 - Sponsor Meeting

    • 04/07/2017 - Individual Component Analysis

    • 04/07/2017 - 1st Design Draft

  • Update Gantt chart.

Budget (list amount spent and amount remaining)
