Abstract
La presente invención se refiere a una barrera de cerumen para una prótesis acústica, que incluye una cubierta que tiene una salida acústica y un receptor colocado dentro de la cubierta, el receptor tiene una compuerta de salida del receptor, caracterizada porque comprende, en combinación un alojamiento adaptado para ser recibido por la cubierta, cuyo alojamiento incluye un pasaje acústico central substancialmente cilíndrico, que conecta a la salida acústica y la compuerta de salida del receptor; el pasaje acústico central substancialmente cilíndrico, define un eje central y está definido por una superficie de pared interior del alojamiento; una pluralidad de proyecciones dentro del pasaje acústico central, substancialmente cilíndrico, las cuales están desplazadas espacial y angularmente con respecto al eje central y cooperan para ocluír completamente el pasaje acústico central, substancialmente cilíndrico; dichas proyecciones son substancialmente perpendiculares al eje central y la superficie de pared interior; las proyecciones definen cooperativamente trampas para proporcionar sitios de acumulación de cerumen dentro del alojamiento, con lo que la migración de cerumen en la prótesis acústica se retarda substancialmente; y un atenuador acústico variable que conjuntamente con las proyecciones definen un medio para regular la respuesta acústica de la prótesis acústica, en donde dicha respuesta acústica puede ser ajustada por el atenuador acústico variable.The present invention relates to an earwax barrier for an acoustic prosthesis, which includes a cover having an acoustic outlet and a receiver placed inside the cover, the receiver has a receiver outlet gate, characterized in that it comprises, in combination a housing adapted to be received by the cover, whose housing includes a substantially cylindrical central acoustic passage, which connects to the acoustic output and the receiver's output gate; the substantially cylindrical central acoustic passage defines a central axis and is defined by an interior wall surface of the housing; a plurality of projections within the central acoustic passage, substantially cylindrical, which are spatially and angularly offset from the central axis and cooperate to completely occlude the central acoustic passage, substantially cylindrical; said projections are substantially perpendicular to the central axis and the interior wall surface; the projections cooperatively define traps to provide earwax accumulation sites within the housing, whereby the migration of earwax in the acoustic prosthesis is substantially retarded; and a variable acoustic attenuator that together with the projections define a means to regulate the acoustic response of the acoustic prosthesis, where said acoustic response can be adjusted by the variable acoustic attenuator.
