Abstract
Abstract A self-retaining voice prosthesis device (1) comprises duct means defining an air passageway for communication with a wearer's trachea and having a rigid flap valve (28) pivotally mounted therein between open and closed positions. The flap valve (28) is designed to be gravity biased into the open motionless position during normal inhalation and exhalation but to be moved into its closed position when a wearer exhales with a greater than normal force, e.g. as when making "speech". An adjustment means (12) is provided for adjusting the gravity biased open position of the flap valve (28). The device (1) suitably includes attachment means (3) separable from the duct means, the attachment means being self-retaining in a wearer's trachea stoma requiring no ties or adhesive to retain it in position. In certain conditions of use, e.g. when the wearer sleeps or rests, the attachment means (3) may be used by itself as a stoma button. <IMAGE>

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
106 words
A voice prosthesis device comprising duct means defining an air passageway for communication with a wearer's trachea, a rigid flap valve pivotally mounted within the duct means for movement between an open position to allow passage of air through said air passageway means and a closed position to block passage of air through said air passageway, the rigid flap valve, in use of the device, being gravity biased into its open position and being moved into its closed position when a wearer exhales with sufficient force into the air passageway, and adjustment means enabling the gravity biased open position of said flap valve to be adjusted.
Claim 2
Dependent Claim
106 words
A voice prosthesis device comprising duct means defining an air passageway for communication with a wearer's trachea, a rigid flap valve pivotally mounted within the duct means for movement between an open position to allow passage of air through said air passageway means and a closed position to block passage of air through said air passageway, the rigid flap valve, in use of the device, being gravity biased into its open position and being moved into its closed position when a wearer exhales with sufficient force into the air passageway, and adjustment means enabling the gravity biased open position of said flap valve to be adjusted.
Claim 3
Dependent Claim
41 words
A device according to claim 1, including safety means designed to enable outflow of air from the duct means when the flap valve is in its closed position on occurrence of a larger than expected air pressure in the duct means.
Claim 4
Dependent Claim
26 words
A device according to claim 2, in which the safety means comprises a safety plug mounted in an opening in a wall of the duct means.
Claim 5
Dependent Claim
20 words
A device according to claim 2, in which the safety means comprises a valved opening communicating with the duct means.
Claim 6
Independent Claim
35 words
A device according to any of the preceding claims, in which the adjustment means comprises an adjustable screw providing an adjustable stop against which the rigid flap valve is positioned when in its open position.
Claim 7
Independent Claim
25 words
A device according to any of the preceding claims, in which the flap valve is mounted in a removable part of the voice prosthesis device.
Claim 8
Dependent Claim
47 words
A device according to claim 6, in which the removable part is designed to be positioned exteriorly of a wearer, when the device is positioned with said air passageway in communication with a wearer's trachea, so that the removable part can be easily removed for cleaning purposes.
Claim 9
Independent Claim
32 words
A device according to any of the preceding claims, including attachment means for enabling detachable attachment of the device to an opening, e.g. a tracheostoma, in a wall of a wearer's trachea.
Claim 10
Dependent Claim
40 words
A device according to claim 8, in which the duct means is detachably attached to the attachment means, the latter being usable by itself when attached to said tracheal opening, e.g. during period of rest or sleep of the wearer.
Claim 11
Independent Claim
19 words
A device according to any of the preceding claims, including external means to prevent inadvertent inhalation of the device.
Claim 12
Dependent Claim
14 words
A device according to claim 10, in which the external means comprises a flange.
Claim 13
Dependent Claim
35 words
A voice prosthesis device constructed and arranged substantially as herein described, with reference to, and as illustrated in, Figures 1 to 7 or Figures 1, 2, 4, 5, 8 and 9 of the accompanying drawings.
Claim 14
Dependent Claim
35 words
A voice prosthesis device constructed and arranged substantially as herein described, with reference to, and as illustrated in, Figures 1 to 7 or Figures 1, 2, 4, 5, 8 and 9 of the accompanying drawings.
Claim 15
Dependent Claim
64 words
A voice prosthesis device, preferably self-retaining, comprising body means defining an air passageway for communication with a wearer's trachea, a rigid flap valve movable between an open position for allowing passage of air through said air passageway and a closed position for blocking passage of air through said air passageway and adjustment means enabling adjustment of the open position of said rigid flap valve.
Claim 16
Dependent Claim
64 words
A voice prosthesis device, preferably self-retaining, comprising body means defining an air passageway for communication with a wearer's trachea, a rigid flap valve movable between an open position for allowing passage of air through said air passageway and a closed position for blocking passage of air through said air passageway and adjustment means enabling adjustment of the open position of said rigid flap valve.
Claim 17
Dependent Claim
71 words
A device according to claim 13, in which the flap valve is pivotally mounted within the body means, the flap valve, in use of the device, being gravity biased into its open position during normal inhalation and exhalation through the air passageway and being moved into its closed position on occurrence of flow of air through the air passageway from the trachea at a flow rate greater than for normal exhalation.
