SPEECH VALVE ASSEMBLY

摘要

A speech valve assembly (1) for connection to the tracheal stoma (2) of a laryngectomee comprises a housing (6) with a passage (26) extending between a proximal end near the tracheal stoma (2) and a free end situated opposite, a filter means (24) situated near the proximal end, and a valve (23) situated on the side of the filter means (24) facing the free end. The valve can comprise a valve body (18) and a valve seat (16), which can be made to interact with each other against an initial tension, under the influence of an air flow (25) from the proximal to the free end through the passage (26) of the housing (6).
