Abstract

A bone conduction hearing aid has a detachable vibrator (1) on a ferromagnetic plate with two magnets (2) arranged in an open U with closed side facing the vibrator and open side the head where a ferromagnetic implant with magnets (3) to hold the unit is placed on or in the skull (5).

Description

Bei Patienten mit schweren Erkrankungen des Mittelohres kann häufig kein Hörgerät über Luftleitung angepasst werden. Bei ihnen kann daher der Schall nur als Knochenschall direkt zum Innenohr unter Umgehung des Schallleitungsapparates des äußeren Ohres und des Mittelohres erfolgen. Die Ankopplung des Festkörperschalls an den Knochen kann mit Hilfe von Vibratoren, die an die Kopfhaut gepresst werden, oder über offene Schraubenimplantate erfolgen. Beide Methoden haben unterschiedliche Nachteile. Dazu zählen einerseits die grundsätzlichen Probleme offener Implantate sowie andererseits der teilweise unangenehme Andruck an den Kopf und der ästhetisch störende Bügel.at Patients with severe middle ear disorders can often not Hearing aid via air line be adjusted. With them, therefore, the sound can only as bone sound directly to the inner ear, bypassing the sound conduction apparatus of the outer ear and the middle ear. The coupling of solid-state sound on the bones can be made with the help of vibrators attached to the scalp be pressed, or over open screw implants done. Both methods have different disadvantages. These include on the one hand the fundamental Problems of open implants as well as the partly unpleasant ones Pressure on the head and the aesthetic disturbing Hanger.

Um die Fixation mit Hilfe eines Bügels zu vermeiden bietet sich eine transkutane, magnetische Fixation an. Dazu werden entweder ein ferromagnetisches Implantat oder ein, zwei bzw. mehrere Magnete auf oder in den Schädelknochen implantiert, die Haut entsprechend den individuellen Erfordernissen ausgedünnt und das externe Hörgerät mit Hilfe eines oder mehrerer Magnete fixiert.Around the fixation with the help of a temple To avoid this is a transcutaneous magnetic fixation at. These are either a ferromagnetic implant or a, two or more magnets implanted on or in the cranial bones, the skin thinned out according to individual requirements and the external hearing aid with help fixed one or more magnets.

Der oder die Magnete erzeugen ein Magnetfeld, das sich ungünstig auf die Leistung des elektromechanischen Vibrators auswirken und zu Leistungseinbußen führen kann. Als Lösung bietet sich die Anwendung von Doppelmagneten an, die auf einer ferromagnetischen Platte fixiert werden. Durch diese Anordnung wird ein „U"-förmiges Magnetfeld er zeugt, welches eine hohe Kraft in Richtung des offenen „U" und damit in Richtung der Implantate ausübt. Die implantierten Magnete werden ohne ferromagnetische Verbindung implantiert. Die externen Magnete befinden sich auf der ferromagnetischen Platte. Der Vibrator befindet sich auf der von den Magnete abgewandten Seite der Platte. Dadurch weist das Magnetfeld zur geschlossenen „U"-Seite, d.h. zum Vibrator hin, nur vergleichsweise geringe Kräfte auf.Of the or the magnets create a magnetic field that is unfavorable affect and increase the performance of the electromechanical vibrator performance degradation to lead can. As a solution lends itself to the application of double magnets on a ferromagnetic Plate to be fixed. By this arrangement, a "U" shaped magnetic field he testifies, which is a high force in the direction of the open "U" and thus in the direction of the implants exercises. The implanted magnets are without ferromagnetic compound implanted. The external magnets are located on the ferromagnetic plate. The vibrator is located on the side facing away from the magnets the plate. As a result, the magnetic field points to the closed "U" side, i.e. to the Vibrator out, only comparatively small forces.

Ein Ausführungsbeispiel ist in 1 dargestellt.An embodiment is in 1 shown.

Die Schallübertragung erfolgt von einem Vibrator (1) in einen Doppelmagneten (2), der aus zwei auf einer ferromagnetischen Platte befindlichen Magneten besteht. Dieser wird durch ein ferromagnetisches Implantat, ein, zwei bzw. mehrere Magnete oder einen analogen Doppelmagneten (3) fixiert. Der Schall wird als Festkörperschall durch die Haut und das subkutane Gewebe (4) in den oder die Magnete und von dort weiter in den unmittelbar anliegenden Knochen (5) übertragen.The sound is transmitted by a vibrator ( 1 ) into a double magnet ( 2 ) consisting of two magnets on a ferromagnetic plate. This is done by a ferromagnetic implant, one, two or more magnets or an analog double magnet ( 3 ) fixed. The sound is transmitted as solid-state sound through the skin and the subcutaneous tissue ( 4 ) into the magnet (s) and from there into the immediately adjacent bone ( 5 ) transfer.

In einer Modifikation ist der Magnet (2) abnehmbar mit dem Vibrator verbunden und kann gewechselt werden, so dass die Andruckkraft durch unterschiedlich starke Magnete variiert werden kann.In a modification, the magnet ( 2 ) detachably connected to the vibrator and can be changed, so that the pressing force can be varied by different strength magnets.
