Physical 3D larynx model with moving partsOctober 31st – 6th, 2008Client: Sherri K. ZelaznyTeam Members: Rexxi Prasasya (Leader)Tu Hoang Anh Mai (Communicator)Karen Chen (BSAC)Jason Tham (BWIG)Problem Statement: The goal of this project is to continue the development of a physical 3D laryngeal model, with moving laryngeal cartilage, bones, membranes, and muscles. We would like to demonstrate nerve-muscle action and interaction in the larynx for voice production. The model is to be used as a patient educational tool for improved understanding of the laryngeal mechanism. It will also be used to plan treatment based on diagnosis of voice, airway and/or swallowing disorder. This semester, we will design a prototype that accurately demonstrates healthy laryngeal muscle movements. In the subsequent semester, we would like to introduce several laryngeal disorders into the model.Last Week’s Goals:- Obtained materials for the tract implementation from hardware store such as Menard’s- Finished the implementation of the arythenoid cartilages tract- Set up a time to meet with Greg to discuss possible muscle model.Summary of Accomplishments:- Ordered the casing for the pin that attaches arytenoid cartilage to the cricoid cartilageThis Week’s Goals:- Start the electronic part of this design- Finished the machining of the arytenoids tract- Complete the movement of the vocal cordProject Difficulties:- We are still waiting for the material for tract to come in, after surveying Menard’s and Jo-Ann fabric, we failed to find a product that is appropriate for our design. We found some metal rod that will be very hard to machine and some wooden rod that will be too fragile to machine. - We would like to have the casing of the pin machined before we drill the tract into the arytenoid cartilage to ensure proper dimensionActivities:Date Person/Group Activity Time Spent10.30.2008 Team Advisor meeting 0.50 hr11. 2.2008 Team Menard’s and Jo-Ann fabric – attempted to obtain material for the track2.00 hrProject Timeline:Week Begins8-Sep15-Sep22-Sep28-Sep6-Oct13-Oct20-Oct26-Oct3-Nov10-Nov17-Nov24-Nov1-DecTaskResearchBrainstormingInitial designPrototypingTestingFinal DesignDeliverablesProgress reportMidsemester reportMidsemester PPTPDSFinal PresentationFinal
