Abstract
Abstract A tracheal stoma valve with a valve housing ( 2 ) has a pivotable valve flap ( 3 ), which is pivotable upon inhalation with an air stream of predeterminable strength into a position sealing off the open lumen ( 4 ) of the valve housing ( 2 ), and upon exhalation with an air stream of predeterminable strength is pivotable into a position at least partially clearing the open lumen ( 4 ) again. Moreover, a bypass valve ( 5 ) is provided, through which breathing air can be inhaled when the valve flap ( 3 ) is located in the closed position. The two mentioned switching points of the valve flap ( 3 ), between the sealing position and the position at least partially clearing the open lumen ( 4 ) of the valve housing ( 2 ), are pre-adjustable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
A tracheal stoma valve comprising a valve housing ( 2 ) having an open lumen ( 4 ) in which a valve flap ( 3 ) is pivotably mounted, the valve flap ( 3 ) being pivotable upon inhalation with a stream of air of a predeterminable strength into a position sealing off the open lumen ( 4 ) and the valve flap ( 3 ) being pivotable upon exhalation with a stream of air of predeterminable strength into a position at least partially clearing the open lumen ( 4 ) again, and a bypass valve ( 5 ) through which respiratory air can be inhaled when the valve flap ( 3 ) is found in the closed position, wherein the valve flap ( 3 ) has two switching points which are pre-adjustable between the position sealing off the open lumen ( 4 ) and the position at least partially clearing the open lumen ( 4 ).
Claim 2
Dependent Claim
157 words
A tracheal stoma valve comprising a valve housing ( 2 ) having an open lumen ( 4 ) in which a valve flap ( 3 ) is pivotably mounted, the valve flap ( 3 ) being pivotable upon inhalation with a stream of air of a predeterminable strength into a position sealing off the open lumen ( 4 ) and the valve flap ( 3 ) being pivotable upon exhalation with a stream of air of predeterminable strength into a position at least partially clearing the open lumen ( 4 ) again, and a bypass valve ( 5 ) through which respiratory air can be inhaled when the valve flap ( 3 ) is found in the closed position, wherein the valve flap ( 3 ) has two switching points which are pre-adjustable between the position sealing off the open lumen ( 4 ) and the position at least partially clearing the open lumen ( 4 ).
Claim 3
Dependent Claim
118 words
The tracheal stoma valve according to claim 1 , wherein at least two permanent magnets ( 6 , 7 ) are arranged on the valve flap ( 3 ), such that one permanent magnet ( 6 ), with a first metallic sliding valve ( 8 ) arranged in the valve housing ( 2 ), forms a magnetic closure in the sealing off position of the valve flap ( 3 ), and a second permanent magnet ( 7 ), with a second sliding valve ( 9 ) arranged in the valve housing ( 2 ), forms a magnetic closure in the position of the valve flap ( 3 ) at least partially clearing the open lumen ( 4 ).
Claim 4
Dependent Claim
35 words
The tracheal stoma valve according to claim 1 , wherein the bypass valve ( 5 ) is constructed as a recoil valve ( 12 , 13 ) integrated into the valve flap ( 3 ).
Claim 5
Dependent Claim
28 words
The tracheal stoma valve according to claim 3 , wherein the second permanent magnet ( 7 ) is arranged on the end of the catch ( 10 ).
Claim 6
Dependent Claim
29 words
The tracheal stoma valve according to claim 2 , wherein a catch ( 10 ) for restricting the pivoting motion is formed on the valve flap ( 3 ).
Claim 7
Dependent Claim
55 words
The tracheal stoma valve according to claim 1 , wherein the valve flap ( 3 ) is eccentrically suspended in the valve housing ( 2 ), such that the center of gravity ( 11 ) of the valve flap ( 3 ) lies below the longitudinal axis (A) of the valve housing ( 2 ).
