Abstract
Abstract The present invention relates to a prosthetic device and more particularly to a tracheal speaking tube which is received within the stoma of a laryngectomee to assist in the creation of speech. The device includes a tube, an air flow altering device and a vibrating device, the vibrations of which cause an internal wall of the esophagus to vibrate to allow the laryngectomee to form speech.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
140 words
A device for creating speech in a laryngectomee comprising: a tube adapted to be received within the trachea of said laryngectomee, said tube including an insertion end and a stoma engaging end; a tissue vibrating means positioned between said insertion end and said stoma engaging end of said tube for causing the tissue of the esophagus to vibrate; and an air flow altering means disposed within said tube for altering the flow of air during exhalation, said altering means positionable between an open position wherein the flow of air is directed outside the body and a closed position wherein the flow of air is directed to said vibrating means, wherein when said flow of air is directed to said tissue vibrating means, said vibrations cause an internal wall of the esophagus to vibrate, which allows said laryngectomee to form speech.
Claim 2
Independent Claim
140 words
A device for creating speech in a laryngectomee comprising: a tube adapted to be received within the trachea of said laryngectomee, said tube including an insertion end and a stoma engaging end; a tissue vibrating means positioned between said insertion end and said stoma engaging end of said tube for causing the tissue of the esophagus to vibrate; and an air flow altering means disposed within said tube for altering the flow of air during exhalation, said altering means positionable between an open position wherein the flow of air is directed outside the body and a closed position wherein the flow of air is directed to said vibrating means, wherein when said flow of air is directed to said tissue vibrating means, said vibrations cause an internal wall of the esophagus to vibrate, which allows said laryngectomee to form speech.

Claim 8
Dependent Claim
28 words
A device as set forth in claim 1, further comprising a sound transporting means for transporting said vibrations to said internal wall of said esophagus of said laryngectomee.
Claim 9
Dependent Claim
16 words
A device as set forth in claim 7, wherein said transport means includes a sound port.
Claim 10
Dependent Claim
23 words
A device as set forth in claim 1, further comprising a securing means for securing said tube within the trachea of the laryngectomee.
Claim 11
Dependent Claim
16 words
