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.

Claims6

Dependent claims

A speech valve for persons having undergone a laryngectomy or tracheotomy, comprising:

a housing having a cover part, a delimiting wall, and a bottom part, air passageway openings formed in each of the cover part and wall, a proximal opening formed in the bottom part;
an annular shaped filter supported around the wall and sealed by the cover part;
a valve element displaceably supported within the wall and which is biased into communication with a central opening of the cover part to permit bi-directional airflow through the housing, the valve element being displaceable in a direction counter to its bias and along a central main axis extending through an interior of the wall to an airflow interrupting position in which the valve element is moved onto a valve seat configured about the proximal opening;
and
wherein the valve element is supported in the housing via at least one spring element, wherein the valve element has at least one bearing for supporting the at least one spring element disposed on at least one of a side wall, an undersurface, and an upper surface thereof.
