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.
