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.
Claims17
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.
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.
