Abstract
To solve the problem of making available a speech valve for persons who have undergone a laryngectomy or tracheotomy, which speech valve in particular has a long useful life, a speech valve is proposed having a housing with a proximal opening and at least one filter at least partially received in the housing, and with a piston-like valve element, wherein the filter at least partially surrounds the valve element, wherein the valve element is movable on a valve seat, arranged on the proximal opening, in order to produce a closure position and can be returned with a spring action to an open position of the speech valve, and wherein the valve element has a lower end which faces towards the proximal opening and which is assigned to the valve seat in the open position and, with the valve seat, forms a gap through which an air stream can be guided.
