Adjustable wave tube stand for Acoustic Reflection Technique Week: October 26th – November 2nd Client: Erin Douglas, MS-CCC-SLP Vocal Tract Development Lab - 430 Waisman Center Phone: 608-263-5610 Email: [email protected] Advisor: Dr. Willis J. Tompkins 2134 Engineering Centers Building Phone: 608-263-1581 Email: [email protected] Team: Ryan Carroll – Team Leader Jeremy Glynn– Communications Andrew Bremer – BWIG Ben Engel – BSAC Problem Statement The Vocal Tract Development lab (VT Lab) plans to compare anatomic measurements secured from Acoustic reflection technology (ART )- also known as acoustic pharyngometry – in the upright and supine position with measurements secured from imaging studies (MRI & CT). Currently, researchers in the VT Lab need to hold the wave tube in their hands which is presenting variability in the data. It is difficult to hold the wave tube at the same angle during each trial within subjects and across subjects. Hood Laboratories, the company who manufactures AR technology, has no plans to offer an adjustable stand. VTLab is requesting for the BME team to design and build a steady stand for the ART wave tube. The stand should be adjustable so that it may be used by individuals of different ages -- young children to adult. Also, the stand must allow the patient's head to remain in a standardized position in the upright and supine position. Another important criterion is that the stand/unit should be easy to clean and disinfect. Last Week’s Goals • Purchase HDPE • Obtain Stand • Obtain shop access for all members • Start building prototype Accomplishments • HDPE Purchased 10/30. The type of HDPE is Ultra High MW HDPE. This type is still compatible with our design. • Stand problem was dealt with. Apparently the stand was not being shipped due toproblems with payment. These were dealt with and the status on the order is now “Ready to Ship” as of 10/31. Should be arriving next week hopefully. • Shop access obtained for all members. • Waiting for HDPE to ship. This Week’s Goals • Obtain HDPE. • Finalize SolidWorks, Mill interface. • Hopefully, obtain stand. Investigate means of attachment of interface to stand. • Test gripping lining with cleaning solution. If needed, purchase gripping lining. • Start assembly. Difficulties • GearTree.com is not recommended for future design students.
