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.
Claims6
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).
