Abstract

The device has a sound tube (3), which is provided for transmission of sound. The sound tube is inserted into a bore (2). An end (5) of the sound tube is melted, so that an outer diameter of the tube`s end is larger than an inner diameter of the bore. The bore is designed in the shape of cone at its end. A casing (4), which is fixed at the sound tube, is arranged at a side of the bore. The casing is manufactured from plastics or rubber. An independent claim is also included for a method for fastening a sound tube in a bore of the hearing device.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Befestigen eines Schallschlauchs in der Bohrung.The present invention relates to a method of attaching a sound tube in the bore.

Seit einiger Zeit werden auf dem Markt Hörgeräte angeboten, welche keine individuellen Otoplastiken benötigen. Die Stelle der Otoplastiken nehmen hier Kunststoffstöpsel ein. Die akustischen Eigenschaften derartiger Stöpsel schränken jedoch die universelle Einsetzbarkeit dieser Hörgerätetypen ein. Um auch stärkere Hörverluste versorgen zu können, kleben Akustiker vielfach anstelle des Stöpsels eine übliche Otoplastik oder eine IDO-Schale (in dem Ohr) an den Schallschlauch.For some time, hearing aids have been offered on the market that do not require individual earmoulds. The location of the earmolds here take plastic plugs. However, the acoustic properties of such plugs limit the universal applicability of these types of hearing aids. In order to be able to provide even greater hearing loss, acousticians often stick a conventional earmold or an IDO shell (in the ear) to the sound tube instead of the plug.

Die bei den Hörgeräten verwendeten Schläuche sind jedoch den üblichen Umgebungsbedingungen ausgesetzt und somit einem verstärkten Alterungsprozess unterworfen. Infolgedessen besteht die Problematik, dass die Schläuche nach einiger Zeit wieder gewechselt werden müssen. Dies ist aber wegen des geringen Durchmessers und des verwendeten Materials der Schläuche nur schwer möglich. Die Otoplastiken und IDO-Schalen können, wenn überhaupt, nur durch Ausbohren des eingeklebten Schlauchstücks wiederverwendet werden. Bei der Wiederverwendung ist das neue Stück Schlauch in der entsprechenden Länge abzuschneiden und wieder in die Bohrung der Otoplastik bzw. IDO-Schale zu kleben.However, the hoses used in the hearing aids are exposed to the usual environmental conditions and thus subjected to an increased aging process. As a result, there is the problem that the hoses must be replaced again after some time. However, this is difficult because of the small diameter and the material used in the hoses. The earmolds and IDO shells can be reused, if at all, only by drilling out the glued-in piece of tubing. When reusing, cut off the new piece of tubing of the appropriate length and glue it back into the hole of the earmold or IDO shell.

Aus der Druckschrift DE 20 2005 004 245 U1 ist eine Im-Ohr-Hörgeräteschale bekannt. Ein Schallschlauch wird mit einem Flansch befestigt, indem der Schlauch über den Flansch gezogen wird. Eine Nut im Flansch dient der Fixierung des Schlauchs.From the publication DE 20 2005 004 245 U1 is an in-ear hearing aid known. A sound tube is attached with a flange by pulling the tube over the flange. A groove in the flange serves to fix the hose.

Weiterhin beschreibt die Patentschrift DE 195 23 991 B4 ein Hörgerät mit einem Hängebügel und einem Schallschlauch. Auch hier weist der Hängebügel an dem Ende, an dem der Schallschlauch übergestülpt wird, eine umlaufende Nut auf.Furthermore, the patent describes DE 195 23 991 B4 a hearing aid with a hanger and a sound tube. Again, the hanger at the end at which the sound tube is slipped over, a circumferential groove.

Schließlich offenbart die Druckschrift DE 94 06 801 U1 einen Schallschlauch, welcher mittels eines angeformten Ringwulstes an dem Stirnabsatz eines rohrförmigen Stutzens gehalten wird.Finally, the document discloses DE 94 06 801 U1 a sound tube, which is held by means of a molded annular bead on the Stirnabsatz a tubular nozzle.

Aus der Druckschrift GB 1 462 899 A1 ist ein Ohrstück für ein Hörgerät bekannt. Das Ohrstück besitzt eine Tasche, die mit einer flüssigen Paste gefüllt ist. Durch sie hindurch verläuft ein Röhrchen, an dessen Ende ein Ring aufgebracht ist. An der anderen Seite wird die Tasche durch einen Kompressionsring auf dem Röhrchen gehalten.From the publication GB 1 462 899 A1 is an ear piece for a hearing aid known. The ear piece has a pocket that is filled with a liquid paste. Through them passes a tube, at the end of a ring is applied. On the other side, the bag is held by a compression ring on the tube.

Des Weiteren ist in der Druckschrift US 3 736 929 A ein selbstformender Ohrstöpsel beschrieben. Er besitzt in der Mitte ein Röhrchen zum Druckausgleich. An beiden Enden des Röhrchens sind feste Elemente angeformt, die ein Verrutschen des Röhrchens in einer Kammer des Ohrstücks verhindern. Das Röhrchen kann an beiden Seiten erhitzt werden, um vergrößerte Endstücke in Form von Ausbauchungen zu erhalten.Furthermore, in the document US 3 736 929 A a self-shaping earplug described. He has a tube in the middle for pressure equalization. At both ends of the tube solid elements are formed, which prevent slipping of the tube in a chamber of the ear piece. The tube can be heated on both sides to obtain enlarged tails in the form of bulges.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, das Wechseln eines Schallschlauchs in einer Hörvorrichtung einfacher zu gestalten.The object of the present invention is therefore to simplify the replacement of a sound tube in a hearing device.

Erfindungsgemäß wird diese Aufgabe gelöst durch ein Verfahren nach Anspruch 1. According to the invention, this object is achieved by a method according to claim 1.

Ein erfindungsgemäß montierter Schlauch kann somit durch einfaches Abschneiden aus der Bohrung entfernt werden, ohne die Bohrung ausdrehen bzw. ausbohren zu müssen. Außerdem kann die Schale oder Otoplastik etwas um den Schlauch gedreht werden, so dass eine Feinanpassung des Winkels möglich ist. Diese Drehmöglichkeit besteht deswegen, weil der Schlauch nicht in die Bohrung geklebt ist. Darüber hinaus ist auch das Einsetzen eines neuen Schlauchs in die Bohrung sehr einfach durch Einziehen möglich. A hose assembled according to the invention can thus be removed from the bore by simply cutting it off, without having to unscrew or drill out the bore. In addition, the shell or earmold can be slightly rotated around the tube, so that a fine adjustment of the angle is possible. This possibility of rotation exists because the hose is not glued into the bore. In addition, the insertion is also a new tube into the hole very easy by pulling possible.

Eine Hörvorrichtung kann eine Hörgeräteschale aufweisen, in der sich die Bohrung befindet. Alternativ kann die Hörvorrichtung auch eine Otoplastik aufweisen, in der die Bohrung angeordnet ist. In beiden Fällen lässt sich dann der Schlauch mühelos direkt an die Hörgeräteschale bzw. die Otoplastik anbringen und von ihr entfernen. A hearing device may comprise a hearing aid shell, in which the bore is located. Alternatively, the hearing device may also have an earmold, in which the bore is arranged. In both cases, the hose can then be easily attached directly to the hearing aid shell or earmold and removed from it.

Alternativ kann die Hörvorrichtung auch einen Adapter aufweisen, in dem sich die Bohrung befindet. Damit ist es möglich, einen beliebig gestalteten Adapter an dem Ende eines Schallschlauchs auf einfache Weise zu befestigen. Ist der Bohrungsinnendurchmesser ausreichend klein gegenüber dem Schlauchaußendurchmesser, ist der Adapter an dem Schlauchende drehbar gelagert.Alternatively, the hearing device may also have an adapter in which the bore is located. This makes it possible to easily attach an arbitrarily designed adapter to the end of a sound tube. If the bore inner diameter is sufficiently small in relation to the hose outer diameter, the adapter is rotatably mounted on the hose end.

Vorzugsweise ist die Bohrung an ihrem einen Ende konusförmig gestaltet. Diese Form hat mehrere Vorteile. Zum einen lässt sich das Schlauchende durch Hineinziehen in diese Form ebenfalls konisch ausbilden. Zum anderen kann durch die Konusflächen eine erhöhte Dichtwirkung erzielt werden. Des Weiteren hat die Konusform auch den Vorteil, dass der gesamte aufgeweitete Abschnitt des Schlauchendes vollständig in der Bohrung untergebracht werden kann.Preferably, the bore is cone-shaped at one end. This form has several advantages. On the one hand, the hose end can also be conically formed by pulling it into this shape. On the other hand, an increased sealing effect can be achieved by the conical surfaces. Furthermore, the cone shape also has the advantage that the entire expanded portion of the hose end can be completely accommodated in the bore.

Wenn sich an der einen Seite der Bohrung das Ende des Schallschlauchs mit dem vergrößerten Außendurchmesser befindet, kann an der anderen Seite der Bohrung eine an dem Schallschlauch fixierte Hülse angeordnet sein. Diese Hülse dient dazu, dass der Schallschlauch nicht von dieser Seite in die Bohrung rutschen kann. Günstigerweise ist die Hülse aus Kunststoff oder Gummi gefertigt. Im Falle von Gummi oder einem gummiartigen Kunststoff kann die Hülse reibschlüssig auf dem Schlauch befestigt werden. Besteht die Hülse jedoch aus einem härteren Kunststoff oder einem anderen harten Material, so kann sie mit dem Schallschlauch verklebt werden. Das Demontieren des Schlauchs kann einfach dadurch erfolgen, dass der Schlauch zwischen Hülse und Bohrung durchtrennt wird.If the end of the sound tube with the enlarged outer diameter is located on one side of the bore, a sleeve fixed to the sound tube can be arranged on the other side of the bore. This sleeve is used so that the sound tube can not slip from this side into the hole. Conveniently, the sleeve is made of plastic or rubber. In the case of rubber or a rubbery plastic, the sleeve can be frictionally secured to the hose. However, if the sleeve is made of a harder plastic or other hard material, so it can be glued to the sound tube. Dismantling of the hose can be done simply by cutting the hose between the sleeve and the bore.

Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert, die einen Schnitt durch eine Komponente einer Hörvorrichtung zeigt, in der ein Schallschlauch erfindungsgemäß fixiert ist.The present invention will now be explained in more detail with reference to the accompanying drawing, which shows a section through a component of a hearing device in which a sound tube is fixed according to the invention.

Das nachfolgend näher geschilderte Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described in more detail below represents a preferred embodiment of the present invention.

In der FIG ist schematisch eine Otoplastik 1 wiedergegeben. Bei der symbolisch dargestellten Otoplastik 1 kann es sich auch um eine IDO-Schale für ein In-dem-Ohr-Hörgerät oder um einen Adapter handeln, der in eine Otoplastik oder in eine Hörgeräteschale eingesteckt wird. In der Otoplastik 1 befindet sich eine Bohrung 2. Diese Bohrung 2 umschließt einen in sie eingeführten Schlauch 3 knapp. Dies bedeutet, dass der Innendurchmesser der Bohrung 2 geringfügig größer als der Außendurchmesser des Schlauchs 3 ist.An earmold 1 is shown schematically in FIG. The symbolically represented earmold 1 may also be an IDO shell for an in-the-ear hearing device or an adapter which is inserted into an earmold or into a hearing device shell. In the earmold 1 is a hole 2. This bore 2 encloses a tube 3 introduced into it just under. This means that the inner diameter of the bore 2 is slightly larger than the outer diameter of the tube 3.

Der Schlauch 3 dient zur Übertragung des Schalls vom Hörgerät in den Gehörgang und ist aus optischen Gründen verhältnismäßig dünn ausgeführt. Typischerweise besitzt er einen Außendurchmesser von weniger als 2,5 mm.The tube 3 is used to transmit the sound from the hearing aid in the ear canal and is made relatively thin for optical reasons. Typically, it has an outer diameter of less than 2.5 mm.

Der dünne Schlauch 3 ist an beiden Seiten der Otoplastik 1 zu sichern, damit er in keiner der beiden Richtungen aus der Bohrung rutschen kann. Aus diesem Grund ist auf dem Schlauch eine Gummi- oder Kunststoffhülse 4 frei verschiebbar angebracht. Bei der Montage wird der Schlauch zunächst auf die richtige Länge abgeschnitten und anschließend mit dem freien Ende durch die Bohrung 2 geschoben.The thin tube 3 is to be secured on both sides of the earmold 1 so that it can not slip out of the hole in either direction. For this reason, a rubber or plastic sleeve 4 is freely slidably mounted on the hose. During assembly, the hose is first cut to the correct length and then pushed with the free end through the hole 2.

Durch Erhitzen des freien Endes erweicht der Kunststoff und auf Grund der Herstellungshistorie (z. B. Strecken beim Extrudieren) oder auf Grund der Oberflächenspannung nimmt das erhitzte Schlauchende eine kugelige Gestalt an bzw. erweitert seinen Gesamtdurchmesser. Das erweiterte Schlauchende 5 lässt sich nach dem Abkühlen nicht mehr durch die Bohrung 2 ziehen.By heating the free end of the plastic softens and due to the production history (eg Extruding) or due to the surface tension, the heated hose end assumes a spherical shape or widened its overall diameter. The extended end of the hose 5 can not be pulled through the hole 2 after cooling.

Eine besonders vorteilhafte Ausgestaltung der Bohrung 2 besteht darin, dass sie an dem Ende, an dem der Schlauch 3 erweitert wird, trichter- bzw. konusförmig gestaltet ist. Dadurch besteht die Möglichkeit, dass der Schlauch mit dem erhitzten, aufgeweiteten Schlauchende 5 in den konischen Bereich 6 der Bohrung 2 zurückgezogen werden kann, wo man ihn schließlich erkalten lässt. Dadurch nimmt das erweiterte Ende 5 des Schlauchs 2 ebenfalls konische Form an, so dass eine erhöhte mechanische Festigkeit sowie eine verbesserte Dichtung zwischen Schlauch und Bohrung erzielt werden kann. Nach dem Einziehen und Fixieren des Schlauchs 2 an der Seite mit dem erweiterten Schlauchende wird der Schlauch 3 nun auch auf der gegenüberliegenden Seite der Bohrung 2 mit Hilfe der Hülse 4 befestigt. Dies erfolgt durch Verschieben der Hülse 4 an die Otoplastik 1 und durch eventuelles Festkleben, falls die Reibungskräfte zwischen Schlauch 3 und Hülse 4 hierzu nicht ausreichend sind. Somit ist der Schlauch 3 in der Bohrung 2 gegen Verschieben in beide Richtungen gesichert.A particularly advantageous embodiment of the bore 2 is that it is funnel-shaped or cone-shaped at the end at which the tube 3 is widened. As a result, there is the possibility that the hose with the heated, expanded hose end 5 can be pulled back into the conical region 6 of the bore 2, where it is finally allowed to cool. As a result, the widened end 5 of the tube 2 also assumes a conical shape, so that an increased mechanical strength and an improved seal between the tube and the bore can be achieved. After pulling in and fixing the hose 2 on the side with the extended end of the hose, the hose 3 is now also fastened on the opposite side of the bore 2 with the aid of the sleeve 4. This is done by moving the sleeve 4 to the earmold 1 and by possibly sticking, if the frictional forces between the tube 3 and sleeve 4 are not sufficient for this purpose. Thus, the tube 3 is secured in the bore 2 against displacement in both directions.

Für das Entnehmen des Schlauchs 3 aus der Bohrung 2 wird die Hülse 4 von der Otoplastik 1 weggezogen, so dass das erweiterte Ende 5 des Schlauchs 3 aus der Bohrung 2 geschoben und abgeschnitten werden kann. Dann lässt sich der Schlauch 3 ohne weiteres aus der Bohrung 2 ziehen.For the removal of the tube 3 from the bore 2, the sleeve 4 is pulled away from the earmold 1, so that the widened end 5 of the tube 3 can be pushed out of the bore 2 and cut off. Then the hose 3 can easily pull out of the hole 2.

Ist die Hülse 4 auf den Schlauch 3 geklebt, so besteht die Möglichkeit, den Schlauch 3 zwischen der Hülse 4 und der Otoplastik 1 mit einem Messer zu durchtrennen. Das in der Bohrung verbleibende Stück des Schlauchs 3 lässt sich dann mit einem Stift ausstoßen.If the sleeve 4 is glued to the tube 3, it is possible to sever the tube 3 between the sleeve 4 and the earmold 1 with a knife. The remaining in the bore piece of the tube 3 can then be ejected with a pin.
