ARTIFICIAL TRACHEA
Document Type and Number:
Japanese Patent JPS59131350
Kind Code:
A
Abstract:
The present invention provides a completely self-contained intraoral larynx comprising a power source, tongue activated controls, power saving signal generation circuitry, acoustic and audio amplifiers, and an intra-oral speaker. These components are contained within an otherwise conventional denture or dental prosthesis. The device produces a high amplitude sound while minimizing current drain from the power source. Laryngectomized patients require only short term training by a speech pathologist to use this device. Intelligible speech is usual within an hour of such training, and facility rapidly improves, The psychological barriers, post-operative physical limitations, aesthetic concerns and limited gestural communication traditionally associated with the use of extra-oral larynges is eliminated by the present invention.
