Voice-producing prosthesis

A prosthesis for placement in the area of the pharynx, an upper region of the trachea ( 1 ) or in a wall ( 5 ) between the esophagus ( 4 ) and an upper region of the trachea ( 1 ) is provided with an air passage ( 16; 46 ) and a vibrating element ( 17, 18; 47; 77; 107, 108 ) for vibrating air.

Beschreibung
Zusammenfassung:	A prosthesis for placement in the area of the pharynx, an upper region of the trachea ( 1 ) or in a wall ( 5 ) between the esophagus ( 4 ) and an upper region of the trachea ( 1 ) is provided with an air passage ( 16; 46 ) and a vibrating element ( 17, 18; 47; 77; 107, 108 ) for vibrating air. Because the prosthesis is provided with a stop ( 20, 21; 56 - 58; 110, 111 ) for abruptly impeding the movability of the vibrating element ( 17, 18; 47; 77; 107, 108 ) in at least one position, sound with a broad spectrum of frequencies is produced which, when speaking, can be effectively converted into the desired sounds. This ensures a highly improved understandability and a more natural voice. According to a practical possibility, the voice prosthesis is incorporated in a one-way valve as a modular part.
