Progress Report 7
Project Title: Ergonomic ultrasound probe
Week of: 3/2/04 – 3/9/04
Group Members:
Yao Lu – BSAC representative
Meghan Olson – BWIG representative
Emily Putzer – Leader
Heather Waldeck – Communicator
Client Information:
Mark Kliewer
Email:
Helpful Resources:
Dr. Nicola Ferrier – Robotics
Dr. Timothy Hall – Mock Transducer Supplier
Dr. Robert Radwin – Ergonomics
Tim Walker – Sonographer
Problem Statement:
During ultrasound procedures, sonographers must apply high levels of force while performing detailed movements, the combination of which increases the number of work-related injuries, especially to the forearm and wrist. Our goal is to develop an ergonomic design to minimize the forces applied and improve the current ultrasound procedure.
Restatement of Team Goals:
Nail down visuals to be used in the presentation to describe each design idea
Finish presentation, divvy up parts, and practice individually
Perfect the PDS
Begin writing mid-semester paper
Summary of Accomplishments:
Heather and Yao attended a meeting with Mark and Tim on 3/2/04 to discuss our design ideas. Our clients were in favor of the mechanical arm design and gave us a few new client requirements, most notably:
1) The focus should be on the echocardiogram and biopsy procedures
2) There are currently many handle re-design ideas in the works and the mechanical arm is a more novel idea
3) The design should most importantly eliminate the applied force for long durations
Yao began piecing together the presentation, Emily added background and some visuals, Heather described the designs and made the evaluation slides, and Meghan provided the complex mechanical arm visual.
We all worked to edit the PowerPoint and prepared individually for the presentation.
Yao and Heather edited the PDS
Heather edited her drawings of the Transducer and Handle redesigns to be included in the presentation.
Meghan finished her SolidWorks representation of the mechanical arm design to also be included in the presentation.
Yao created an outline for the paper, and we have decided who will write which portion of the paper. Yao also has written the PDS, Design 1, and Additional Requirements sections of the paper.
