Patent

CA 2076682

The invention relates to a process for making otoplasty or adaptive ear pieces individually matched to the shape of an auditory canal and consists of the following steps: a) direct or indirect tracing of the shape of the auditory canal and conversion of the values obtained into digital form; b) conversion of the digital representation of this shape into a multi-dimensional computer model of the outer shape of otoplasty or adaptive ear piece; c) selection of the various components/functions for the inside of the computer model with simultaneous establishment of the wall thickness and optimisation of the positions of the components/functions for best possible operation and minimum bulk; d) computer controlled production of an otoplasty or adaptive ear piece from the data thus obtained from the optimised, three-dimensional computer representation of the otoplasty or adaptive ear piece.

L'invention concerne un procédé pour fabriquer des appareils auditifs spécialisés adaptés individuellement à la forme du canal auditif et qui comprend les étapes suivantes : a) traçage direct ou indirect de la forme du canal auditif et conversion des valeurs obtenues sous forme numérique; b) conversion de la représentation numérique de cette forme en un modèle informatique multidimensionnel de la forme externe de l'appareil auditif spécialisé; c) sélection des divers constituants/fonctions à placer à l'intérieur du modèle informatique avec détermination simultanée de l'épaisseur des parois et optimisation de la position des constituants/fonctions pour obtenir le meilleur rendement possible et la plus grande compacité; d) production assistée par ordinateur d'un appareil auditif spécialisé à partir des données ainsi obtenues grâce à la représentation informatique tridimensionnelle optimisée de l'appareil auditif spécialisé.
