Abstract
Abstract A tracheostoma valve includes a shut-off valve member (1) capable of shutting off the valve in response to an egressive air thrust. The valve includes a blow-off valve member (2) of a design such that the valve can open in response to an overpressure in the trachea which exceeds a given value. This blow-off valve member limits the maximum achievable overpressure behind the valve. Coughing is possible without prior operation of the valve and leakage due to excessive overpressure in the trachea is prevented. The valve may contain a tissue connector and a housing to be connected thereto.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
91 words
A tracheostoma valve with a shut-off valve member capable of shutting off the tracheostoma valve in response to an air displacement, and a blow-off valve member which opens in response to a particular overpressure achieved, and a magnet closure for holding the shut-off valve member (1) in the closed position, with a first part (6) of the magnet closure being slidable relative to a second part (7) of said magnet closure, in a direction transverse to the opening direction of the shut-off valve member (1), for adjusting the over pressure position.
Claim 2
Dependent Claim
91 words
A tracheostoma valve with a shut-off valve member capable of shutting off the tracheostoma valve in response to an air displacement, and a blow-off valve member which opens in response to a particular overpressure achieved, and a magnet closure for holding the shut-off valve member (1) in the closed position, with a first part (6) of the magnet closure being slidable relative to a second part (7) of said magnet closure, in a direction transverse to the opening direction of the shut-off valve member (1), for adjusting the over pressure position.
Claim 3
Dependent Claim
25 words
A valve according to claim 1 and said blow-off valve member (2) comprises an opening (4) which is closable by the shut-off valve member (1).
Claim 4
Dependent Claim
50 words
A valve according to claim 1, further comprising a first part (9) of said magnet closure being slidable relative to a second part (10) of said magnet closure in a direction transverse to the opening direction of blow-off valve member (2), for adjusting the effective overlap of the magnet closure.
Claim 5
Dependent Claim
18 words
A valve according to claim 1, further comprising said valve having a passage with a substantially rectangular cross-section.
Claim 6
Dependent Claim
28 words
A valve according to claim 1, further comprising a housing (13) and a tissue connector (14), with the housing (13) being detachably mounted in the tissue connector (14).
Claim 7
Dependent Claim
28 words
A valve according to claim 5, characterized in that the tissue connector (14) comprises a thin-walled flange (18) of biocompatible material, extending in radial direction around the valve.
Claim 8
Dependent Claim
18 words
A valve according to claim 6, characterized in that the flange (18) is made of coarse-mesh polypropylene gauze.
Claim 9
Dependent Claim
15 words
A tissue connector for use as a part of a valve according to claim 5.
Claim 10
Dependent Claim
14 words
A housing for use as a part of a valve according to claim 5.
Claim 11
Dependent Claim
101 words
A tracheostoma valve with a shut-off valve member capable of shutting off the tracheostoma valve in response to an air displacement, and a blow-off valve member which opens in response to a particular overpressure achieved on one side thereof; and a magnet closure for holding the shut-off valve member (1) in the closed position, with a first part (6) of the magnet closure being slidable relative to a second part (7) of said magnet closure, in a direction transverse to the opening direction of the shut-off valve member (1), for adjusting the overpressure by varying an overlap of the magnet closure.
Claim 12
Dependent Claim
101 words
A tracheostoma valve with a shut-off valve member capable of shutting off the tracheostoma valve in response to an air displacement, and a blow-off valve member which opens in response to a particular overpressure achieved on one side thereof; and a magnet closure for holding the shut-off valve member (1) in the closed position, with a first part (6) of the magnet closure being slidable relative to a second part (7) of said magnet closure, in a direction transverse to the opening direction of the shut-off valve member (1), for adjusting the overpressure by varying an overlap of the magnet closure.
Claim 13
Dependent Claim
22 words
A valve according to claim 10, characterized by a magnet closure for holding the blow-off valve member (2) in the closed position.
Claim 14
Dependent Claim
18 words
A valve according to claim 10, further comprising said valve having a passage with a substantially rectangular cross-section.
Claim 15
Dependent Claim
28 words
A valve according to claim 10, further comprising a housing (13) and a tissue connector (14), with the housing (13) being detachably mounted in the tissue connector (14).
Claim 16
Dependent Claim
28 words
A valve according to claim 13, characterized in that the tissue connector (14) comprises a thin-walled flange (18) of biocompatible material, extending in radial direction around the valve.
Claim 17
Dependent Claim
18 words
A valve according to claim 14, characterized in that the flange (18) is made of coarse-mesh polypropylene gauze.
Claim 18
Dependent Claim
15 words
A tissue connector for use as a part of a valve according to claim 13.
Claim 19
Dependent Claim
