Description

Die Erfindung bezieht sich auf eine Cerumenschutzvorrichtung für die Schallaustrittsöffnung an Gehäusen oder Ohrpaßstücken von Hörgeräten, wobei an einem Schallaustrittsstutzen eine gelochte Kappe anbringbar ist.The invention relates to a cerumen protection device for the sound outlet opening on housings or ear molds of hearing aids, a perforated cap being attachable to a sound outlet nozzle.

Durch das Gebrauchsmuster DE-U-19 51 165 ist bereits ein Indem-Ohr-Hörgerät bekannt, bei dem auf dem Schallausgangsstutzen ein zylindrischer Körper aufsetzbar ist, der in seinem Inneren eine kammerartige Erweiterung einer Durchbohrung aufweist, in der eine Schicht aus porösem, schalldurchlässigem Material angeordnet ist. Der vom Hörer des Hörgerätes in die Durchbohrung gelangende Schall kann die Schicht aus porösem Material also gut passieren. Ohrschmalz (Cerumen), das im Inneren des Gehörganges abgesondert wird, kann jedoch in umgekehrter Richtung aufgrund der porösen Schicht nicht in das Innere des Hörgerätes gelangen. Eine vergleichbare Anordnung zeigt auch DE-B-12 63 849.The utility model DE-U-19 51 165 already discloses an in-the-ear hearing device in which a cylindrical body can be placed on the sound outlet connector and has a chamber-like extension of a through-hole in its interior, in which a layer of porous, sound-permeable Material is arranged. The sound coming into the through-hole from the receiver of the hearing aid can therefore pass through the layer of porous material well. Earwax (cerumen), which is secreted inside the ear canal, cannot reach the inside of the hearing aid in the opposite direction due to the porous layer. A comparable arrangement is also shown in DE-B-12 63 849.

Durch die DE-U-84 36 783 und 85 04 765 sind darüber hinaus Lochkappen vorbekannt, die auf die Schallausgangsstutzen entweder direkt eines In-dem-Ohr-Hörgerätes oder eines in das Ohr einsetzbaren Ohrpaßstückes eines Hinter-dem-Ohr-Hörgerätes aufbringbar sind (z.B. ansteckbar oder anschraubbar). Die Lochkappen gewährleisten ungehinderten Schallaustritt. Ohrenschmalz, das im Gehörgang abgesondert wird, wird von den Öffnungen weitgehend ferngehalten, da aufgrund von Einformung von Nischen etc. relativ lange Kriechwege vorhanden sind.DE-U-84 36 783 and 85 04 765 also provide perforated caps which can be applied to the sound outlet either directly from an in-the-ear hearing aid or an ear fitting of a behind-the-ear hearing aid which can be inserted into the ear (eg attachable or screwable). The perforated caps ensure unimpeded sound emission. Earwax, which is secreted in the ear canal, is largely kept away from the openings, since due to the formation of niches etc. there are relatively long creepage distances.

Die im Stand der Technik angegebenen Lösungen zur Verhinderung des Einkriechens von Ohrenschmalz sind aber immer noch relativ ungünstig. Zumindest müssen die jeweiligen Schutzvorrichtungen relativ häufig ausgewechselt bzw. gereinigt werden. Ein weiterer Nachteil ist, daß bei den bisher bekannten Lösungen kein Schutz gegen das Eindringen von Feuchtigkeit, insbesondere Schweiß, der im Inneren des Ohrkanals entsteht, in Richtung Hörer existiert. Die Fernhaltung von Schweiß ist insbesondere bei In-dem-Ohr-Hörgeräten von besonderer Wichtigkeit, weil der Weg von der Schallausgangsstelle bis zum Hörer relativ kurz ist und erfahrungsgemäß der sehr aggressive Schweiß den Hörer sehr schnell beschädigt. Aber auch bei Hinter-dem-Ohr-Hörgeräten ist ein solcher Schutz von Nöten, da trotz relativ langen Weges bis zum Hörer es dennoch immer wieder zu Hörerbeschädigungen kommt.However, the solutions given in the prior art for preventing ear wax creeping in are still relative unfavorable. At least the respective protective devices have to be replaced or cleaned relatively frequently. Another disadvantage is that in the previously known solutions there is no protection against the penetration of moisture, in particular sweat, which arises in the interior of the ear canal, in the direction of the listener. Keeping sweat away is particularly important with in-the-ear hearing aids because the path from the sound output point to the listener is relatively short and experience shows that the very aggressive sweat damages the listener very quickly. But such protection is also necessary for behind-the-ear hearing aids, because despite the relatively long way to the listener, there is always damage to the listener.

Aufgabe vorliegender Erfindung ist es, eine Vorrichtung der eingangs genannten Art anzugeben, die bei Verschmutzung mit Ohrenschmalz sehr viel einfacher als bisher zu reinigen ist und die gleichzeitig verhindert, daß überhaupt Feuchtigkeit, insbesondere Schweiß, aus dem Gehörgang, durch die jeweilige Öffnung in das Hörgerät gelangen kann.The object of the present invention is to provide a device of the type mentioned which is much easier to clean when contaminated with ear wax and which at the same time prevents moisture, in particular sweat, from the ear canal through the respective opening into the hearing aid can reach.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing features of claim 1.

Die mikroporöse Membrane aus antihaftendem Material verhindert gleichermaßen das Eindringen von Ohrenschmalz (wegen der sehr kleinen Poren) und von Feuchtigkeit, insbesondere Schweiß (wegen der Ausbildung der Membrane aus antihaftendem Material), in das Innere des Hörgerätes. Antihaftendes Material läßt nämlich Schweißtropfen nicht flach werden, so daß die Tropfen auch nicht in die Mikroporen eindringen können. Wegen der antihaftenden Wirkung läßt sich aber auch das angesetzte Ohrenschmalz leichter als bisher wieder entfernen, z.B. auch mit Hilfe von Ultraschall. Eine Membrane aus Polytetrafluoräthylen hat sich als besonders geeignet für den vorliegenden Zweck erwiesen.The microporous membrane made of non-stick material also prevents ear wax (due to the very small pores) and moisture, especially sweat (due to the membrane being made of non-stick material) from entering the hearing aid. Non-stick material does not let sweat drops become flat, so that the drops cannot penetrate into the micropores. Because of the non-stick effect, the ear wax can be removed more easily than before, for example with the help of ultrasound. A membrane made of polytetrafluoroethylene has proven to be particularly suitable for the present purpose.

Die Kappe 13 der Figuren 14 und 15 beinhaltet eine äußere Ringnut 41, die beim Einsetzen der Kappe in die Schalleintrittsöffnung 11 in den Öffnungsrand einrastet.In FIGS. 4 to 11, all caps 12.1 to 12.4 thus have an internal thread 31. The caps in FIGS. 4 to 9 also include a single central opening 32 on the front side. The same applies to caps 13 in FIGS. 14 and 15. The caps in FIGS 13 to 13 comprise individual small holes 33. The caps of FIGS. 12 and 13 do not comprise an internal thread, but rather a circumferential bead 34 which fits into the respective undercut on the sound outlet connector of the respective hearing aid or earpiece. In FIGS. 16 and 17, the sound outlet connector is indicated at 35 and the ventilation hole at 36. The cap 30 comprises holes 37 and holes 38 for the opening of the sound outlet connector 35 and the ventilation hole 36. The cap 30 is again provided with a circumferential bead 39 which fits into the indicated undercut 40. The cap 13 of Figures 14 and 15 includes one outer annular groove 41 which engages in the opening edge 11 when the cap is inserted into the sound opening.

In sämtlichen Ausführungsbeispielen der Figuren 4 bis 17 ist nun - wie zuvor schon erwähnt - eine unter dem Handelsnamen GORE-TEX® erhältliche mikroporöse Polytetrafluoräthylen-Membrane 14 eingesetzt. In den verschiedenen Figuren sind die einzelnen Membranen wieder mit 14.1 bis 14.7 bezeichnet.In all of the exemplary embodiments in FIGS. 4 to 17, a microporous polytetrafluoroethylene membrane 14 which is available under the trade name GORE-TEX® is now used, as already mentioned above. In the various figures, the individual membranes are again labeled 14.1 to 14.7.

In den Figuren 4 und 5 ist dabei z.B. die Membrane 14.1 in der dargestellten Weise in den Innenraum der Kappe 12.1 eingelegt oder befestigt.In Figures 4 and 5, e.g. the membrane 14.1 inserted or fastened in the manner shown in the interior of the cap 12.1.

In den Figuren 6 und 7 ist die Membrane 14.2 auf die Stirnfläche der Kappe 12.2 in der dargestellten Weise aufgesetzt.In Figures 6 and 7, the membrane 14.2 is placed on the end face of the cap 12.2 in the manner shown.

In den Figuren 8 und 9 ist die Membrane 14.3 z.B. in die Öffnung 32 der Kappe 12.3, wie dargestellt, eingespritzt.In Figures 8 and 9 the membrane 14.3 is e.g. injected into the opening 32 of the cap 12.3, as shown.

In den Figuren 10 bis 13 ist die Membrane 14.4 bzw. 14.5 wiederum ähnlich wie in den Figuren 4 und 5 in die jeweilige Kappe 12.4 bzw. 12.5 eingelegt bzw. befestigt.In FIGS. 10 to 13, the membrane 14.4 or 14.5 is again inserted or fastened into the respective cap 12.4 or 12.5 in a manner similar to that in FIGS. 4 and 5.

Dasselbe gilt auch für die Ausführungsbeispiele der Figuren 14 bis 17 mit den Membranen 14.6 bzw. 14.7.The same also applies to the exemplary embodiments in FIGS. 14 to 17 with the membranes 14.6 and 14.7.

Wie eingangs bereits geschildert, ist die jeweils eingesetzte Membrane 14 jeweils gut schalldurchlässig, schützt jedoch das jeweils eingesetzte Hörgerät gegen das Eindringen sowohl von Ohrschmalz als auch von Feuchtigkeit, insbesondere Schweiß aus dem Ohrkanal. Da der Schweiß ferngehalten wird, werden empfindliche Bauteile des Hörgerätes nicht der Gefahr einer Beschädigung durch Korrosion od.dgl. ausgesetzt. Das eingesetzte Membranematerial ist erfahrungsgemäß bis 0,65 bar wasserdicht und kann somit bei Bedarf auch in einem Ultraschallbad gereinigt werden, ohne daß dabei empfindliche elektronische Bauteile des Hörgerätes, insbesondere der Hörer, beschädigt werden. Es ist also nicht mehr länger erforderlich, wie bisher Kappen komplett auszuwechseln; die cerumenverschmutzte Kappe kann also am Hörgerät verbleiben. Es ist lediglich erforderlich, das Hörgerät oder das Ohrpaßstück, das ja durch die eingesetzte Membrane wasserdicht ausgebildet ist, teilweise in das Ultraschallbad einzutauchen und darin zu reinigen. Nach der Reinigung steht das jeweilige Gerät mit der immer noch aufgeschraubten Kappe wieder ohne weitere Manipulation optimal gereinigt funktionsfähig zur Verfügung.As already described at the beginning, the membrane 14 used in each case is well permeable to sound, but protects the hearing aid used in each case against the penetration of both ear wax and moisture, in particular sweat from the ear canal. Since sweat is kept away, sensitive components of the hearing aid are not at risk of being damaged by corrosion or the like. exposed. Experience has shown that the membrane material used is water-resistant to 0.65 bar and can therefore also be cleaned in an ultrasonic bath if required, without the need for sensitive electronic components Hearing aid, especially the handset, are damaged. It is no longer necessary to completely replace caps as before; the cerumen-soiled cap can therefore remain on the hearing aid. It is only necessary to partially immerse the hearing aid or the earmold, which is made watertight by the membrane used, in the ultrasonic bath and to clean it. After cleaning, the respective device with the cap still screwed on is available in a fully functional, functional condition without any further manipulation.
