This device will allow patients to improve and extend their lives by strengthening their tongue through proper exercise. Last semester, we started making a working prototype with a boil and bite mouth guard as our mouthpiece and a two project boards. A pressure sensor was connected to one of the boards and communicated wirelessly via a IR signal the pressure exerted on the sensor to the other project board that provided audio and visual feedback to the user. This feedback was made to provide the user information in a simple manner as to how well they are doing. This semester we have improved on this working prototype having the characteristics described in our proposed solution. iTable of ContentsTongue Trainer.........................................................................................................................iFinal Report..................................................................................................................................iTable of Contents.........................................................................................................................iiProblem Statement.....................................................................................................................iiiIntroduction..................................................................................................................................1Oral Anatomy and Physiology of the Ideal Swallowing Process................................................1Dysphagia................................................................................................................................2Design Process and Prototype Description..................................................................................3Device Specifications..............................................................................................................3Mouthpiece..............................................................................................................................4Sensor......................................................................................................................................7Feedback..................................................................................................................................9Communication and Signal Flow..........................................................................................11Zilog Z8Encore......................................................................................................................12Programming the Development Board..................................................................................13Future Work...............................................................................................................................19References:................................................................................................................................20Appendix A: Signal Flow for Tongue Trainer...........................................................................22Appendix B: Product Design Specifications............................................................................32Function.................................................................................................................................32Client Requirements..............................................................................................................32Design Requirements.............................................................................................................32Appendix C - Analog and Digital Signals.................................................................................35Definitions.............................................................................................................................35Analog to Digital Conversion................................................................................................36 Appendix D – Polymorph MSDS..............................................................................................41 Appendix E – Mouthpiece Electronics Schematic ...................................................................50iiProblem StatementThe purpose of our project for the senior design class is to make a device to facilitate tongue strengthening exercises to help people who suffer from dysphagia. Dysphagia is the impairment or inability to swallow properly creating a decrease in the quality of life. Millions ofelderly are affected by this problem, making dysphagia a very significant disorder. Our design isa modification of a previous device that is currently used in clinical settings to give feedback to patients during their tongue exercises. The device needs to be usable by the patients in their homes. Our final design is a two part, wireless system, including an oral apparatus that senses the pressure exerted by the tongue on the palate of the mouth, and a second apparatus that displays the information in a simple, comprehensible manner.iiiIntroductionThis design project seeks to aid treatment of swallowing disorders. Swallowing is a complex process; nearly 50 muscle pairs must work in concert to prepare and move a food bolus.Disorders of swallowing affect millions of people, with consequences ranging from mild to deadly. Research has shown that these disorders can be treated by exercise. This report details the progress of a biomedical engineering
