Abstract

The hearing aid has a microphone, loudspeaker, battery and other electrical and electronic components. A tubular body (1) leads outwards from between elements in the pars petrosa region and the outer ear (7) through an opening in the outer ear to open into the ear canal (4). The free end of the tubular body (1) can be connected to the sound outlet opening of a device mounted behind the ear. The free end of the tubular body carries the microphone and loudspeaker. The end of the tube carrying the microphone is extended to the upper section of the outer ear and opens to the front.

Description

Die Erfindung bezieht sich auf einen Rohrkörper zur Schallübermittlung.The invention relates to a tubular body for sound transmission.

Insbesondere Hinter-dem-Ohr-Hörgeräte sind in großem Umfang im Einsatz, wobei die Schallübertragung über den äußeren Gehörgang zum Trommelfell erfolgt. Bei Hinter-dem-Ohr-Hörgeräten wird der Schall vom Mikrophon des Hörgerätes aufgenommen, nach audiologischer Vorgabe verstärkt und über den galvanisch angekoppelten Hörer abgestrahlt. Am Höreraustritt befindet sich in der Regel ein Hörwinkel oberhalb der Ohrmuschel für die Aufnahme eines Schallschlauches, der mittels einer Otoplastik in den äußeren Gehörgang führt. Somit strahlt der vom Hörgerät verstärkte Schall über den Schallschlauch und den Schallkanal oberhalb und dann vor der Ohrmuschel über die Otoplastik direkt in den Gehörgang und somit auf das Trommelfell.Behind-the-ear hearing aids in particular are on a large scale in use, the sound transmission through the outer ear canal to the eardrum. Behind-the-ear hearing aids the sound is picked up by the microphone of the hearing aid, reinforced according to audiological requirements and via the radially coupled headphones emitted. At the handset exit there is usually a hearing angle above the pinna for the inclusion of a sound tube, which by means of a Otoplasty leads into the external ear canal. So the shines Sound amplified by the hearing aid via the sound tube and the sound channel above and then in front of the pinna over the Otoplasty directly in the ear canal and thus on the eardrum.

Nachteilig bei diesen bekannten Hörgeräten wurde aber empfunden, daß die Schallführung, d. h. also der Schallschlauch, immer sichtbar vom Hinter-dem-Ohr-Hörgerät vor der Ohrmuschel in den äußeren Gehörgang verläuft. A disadvantage of these known hearing aids was felt, however, that the sound guidance, d. H. so the sound tube, always visible from behind-the-ear hearing aid in front of the auricle runs into the outer ear canal.

Es sind auch bereits sogenannte In-dem-Ohr-Hörgeräte vorgeschlagen worden, die diesen Nachteil nicht aufweisen, insbesondere dann, wenn die sichtbare Fläche des In-dem-Ohr-Hörgerätes der Hautfarbe des jeweiligen Patienten angepaßt ist. Nachteilig bei diesen Anordnungen ist aber, daß der Gehörgang verschlossen wird, also nicht mehr offen ist, was von vielen Patienten als unangenehm empfunden wird.So-called in-the-ear hearing aids have also already been proposed that do not have this disadvantage, in particular when the visible area of the in-the-ear hearing aid is adapted to the skin color of the respective patient. A disadvantage of these arrangements is that the ear canal is closed, so it is no longer open, which of many Patient is felt to be uncomfortable.

In der US 30 68 954 wird vorgeschlagen, daß in das Ohr ein Paßstück eingesetzt wird, das auch als

Figure 00020001
Plug" bezeichnet wird. In diesem Ohrpaßstück sind drei Kanäle ausgearbeitet, wobei zwei Kanäle eine offene Verbindung zur Außenatmosphäre herstellen.In US 30 68 954 it is proposed that a fitting is used in the ear, which also as
Figure 00020001
Plug "is designated. In this earmold, three channels are worked out, two channels creating an open connection to the outside atmosphere.

Das eigentliche Hörgerät, das beispielsweise hinter dem Ohr getragen wird, durchquert die Ohrmuschel mittels einer Schallleitung, die durch eine Öffnung in der Ohrmuschel führt, und zwar im Bereich der Cavum Conchae.The actual hearing aid that is worn behind the ear, for example crosses the auricle using a sound conductor, which leads through an opening in the auricle, and in the area of the Cavum Conchae.

Die Verbindung zwischen Gehörgang und Hörgerät oder Hörhilfe führt also durch die Ohrmuschel und ist stets sichtbar. Dies zeigt besonders deutlich die Fig. 5.The connection between the ear canal and the hearing aid or hearing aid leads through the auricle and is always visible. this shows 5 is particularly clear.

Auch die Anordnung nach Fig. 9 zeigt deutlich, daß nach außen hin ein Hörgerät oder eine Hörhilfe zu sehen ist, wobei bei dieser Ausführungsform der Gehörgang nicht durch ein Paßstück besetzt ist, aber er wird nach außen hin im wesentlichen durch ein Bauteil abgedeckt.The arrangement according to FIG. 9 clearly shows that towards the outside towards a hearing aid or hearing aid can be seen, with this Embodiment of the ear canal not occupied by a fitting is, but it is essentially outward through a Component covered.

In der US.PS 38 44 271 wird vorgeschlagen, ein hinter dem Ohr angeordnetes Hörgerät mit dem eigentlichen Hörer durch ein Verbindungselement mit dem in das Ohr einzuführenden Stöpsel zu verbinden. Dieses Verbindungselement soll unmittelbar durch die Ohrmuschel hindurchgeführt werden. Der Durchstich erfolgt in der Helix und der Anti-Helix. Bei dieser Anordnung ist das Verbindungselement von außen sichtbar. In US.PS 38 44 271 it is proposed a behind the ear arranged hearing aid with the actual listener through a Connection element with the plug to be inserted into the ear connect to. This connecting element is said to be immediate through the auricle. The breakthrough takes place in the helix and the anti-helix. With this arrangement the connecting element is visible from the outside.

Bei dieser Anordnung ist das Ohr vollständig verschlossen und als besonders nachteilig wird empfunden, daß das Verbindungsteil so weit außerhalb des Kopfknochens liegt, daß es bei einer Drehbewegung im Bett unbedingt störend wirken muß.With this arrangement, the ear is completely closed and it is found to be particularly disadvantageous that the connecting part so far outside of the head bone that one Rotational movement in bed must be disruptive.

Der Erfindung liegt die Aufgabe zugrunde, eine Schallübermittlungsvorrichtung zu schaffen, die möglichst unsichtbar angebracht werden kann, gleichzeitig aber auch die Schallübermittlung verbessert und durch die der Gehörgang nicht vollständig verschlossen wird.The invention has for its object a sound transmission device to create the most invisible attached can be, but also the sound transmission improved and through which the ear canal is not completely is closed.

Diese der Erfindung zugrundeliegende Aufgabe wird durch einen Rohrkörper gelöst, dessen eines Ende nach außen hinter dem Ohr zwischen dem Schläfenbein im Bereich des Pars petrosa und der Ohrmuschel hinter der Ohrmuschel mündet und dessen anderes Ende gehörgangseitig im Gehörgang mündet und am gehörgangseitigen Ende das Trommelfell beschallt.This object on which the invention is based is achieved by a Disconnected tubular body, one end of which is behind the Ear between the temporal bone in the area of the pars petrosa and the auricle opens behind the auricle and its other end opens into the ear canal and on end of the eardrum is sonicated.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous configurations are explained in the subclaims.

So wird einmal vorgeschlagen, daß der Rohrkörper an seinem freien Ende an die Schallaustrittsöffnung eines Hinter-dem-Ohr-Hörgerätes anschließbar ist. Weiterhin wird vorgeschlagen, daß der Rohrkörper selbst als Hörgerät ausgebildet ist und im Bereich des freien Endes das Mikrophon und am gehörgangseitigen Ende den Hörer trägt.So it is once proposed that the tubular body on his free end to the sound outlet opening of a behind-the-ear hearing aid can be connected. It is also proposed that the tubular body itself is designed as a hearing aid and in the area the free end of the microphone and the ear canal End of the phone.

Der Rohrkörper kann auch nur den Hörer tragen und mit einem externen Gerät zur Aufnahme der Schallinformationen verbunden sein.The tube body can also only carry the handset and with one external device connected to record the sound information his.

Wird der Rohrkörper an ein Hinter-dem-Ohr-Hörgerät angeschlossen, ist es wichtig, daß ein leichter, aber dichter Anschluß möglich ist, und so wird vorgeschlagen, eine zwischen dem Schallaustrittstutzen des Hörgerätes und einer Schalleitung vorgesehene Dichtmuffe einzusetzen, die eine nahezu spannungslose, aber schallwellendichte Verbindung der Wandung des Schallaustrittsstutzens mit der Wandung der Schalleitung z. B. des retroaurikulären Rohrkörpers ermöglicht.If the tube body is connected to a behind-the-ear hearing aid, it is important that a light but tight connection is possible, and so it is suggested that one between the Sound outlet of the hearing aid and a sound line provided To use a sealing sleeve that provides an almost tension-free, but sound wave tight connection of the wall of the Sound outlet with the wall of the formwork line z. B. of the retroauricular tubular body.

Der Rohrkörper kann aus Kunststoff bestehen, wird aber vorzugsweise gemäß der Erfindung aus Titan hergestellt, womit er die erforderliche Festigkeit und Gewebeverträglichkeit aufweist. Wird der Rohrkörper aus Titan hergestellt, wird er vorzugsweise dreiteilig ausgebildet und besteht aus einem Ohrstück, einem Außenstück und einem Verbindungskörper, wobei das Ohrstück und das Außenstück in den Verbindungskörper eingeschraubt werden können, so daß dadurch gleichzeitig auch Längenverstellungen des eigentlichen Rohrkörpers möglich sind.The tubular body can be made of plastic, but is preferred made of titanium according to the invention, with which he has the required strength and tissue compatibility. If the tubular body is made of titanium, it is preferred formed in three parts and consists of an ear piece, one Outer piece and a connecting body, the ear piece and screwed the outer piece into the connecting body can be, so that thereby also length adjustments of the actual tubular body are possible.

Insbesondere dann, wenn der Rohrkörper aus Titan besteht, erscheint es vorteilhaft, dafür Sorge zu tragen, daß eine sichere Lage des Rohrkörpers in der Körperöffnung gewährleistet ist, was vorzugsweise dadurch erreicht wird, daß die Außenseite des Rohrkörpers rutschfest gestaltet wird. Dies kann einmal durch eine entsprechende Aufrauhung oder partielle Verdickungen der Außenseite erfolgen, kann aber in gleicher Weise auch dadurch erfolgen, daß auf der Außenseite eine Art Gewinde angebracht wird, das dann auch die Möglichkeit gibt, ohne Hautverletzungen den Rohrkörper in der Körperöffnung zu verstellen. Natürlich können diese Maßnahmen auch dann vorgesehen werden, wenn der Rohrkörper aus Kunststoff besteht.Especially when the tubular body is made of titanium appears it is advantageous to ensure that a safe Position of the tubular body in the body opening is ensured, which is preferably achieved in that the outside of the tubular body is designed to be non-slip. This can be done once through a corresponding roughening or partial thickening the outside, but can be done in the same way also done in that a kind of thread on the outside is attached, which then also gives the possibility without Skin injuries to adjust the tubular body in the body opening. Of course, these measures can also be provided if the tubular body is made of plastic.

Mit anderen Worten ausgedrückt wird gemäß der vorliegenden Erfindung vorgeschlagen, daß ein Rohrkörper konzipiert wird, der mit einer Schallsignalaufnahme hinter dem Ohr versehen wird, nämlich zwischen Schläfenbein im Bereich des Pars petrosa und Ohrmuschel, so daß die Schallführung nicht sichtbar von hinten durch eine Körperöffnung in den Gehörgang des äußeren Ohres geführt wird und somit das Trommelfell beschallt werden kann. In other words, according to the present Invention proposed that a tubular body is designed which has a sound signal recording behind the ear between the temporal bone in the area of the pars petrosa and pinna so that the sound guide is not visible from behind through a body opening into the ear canal outer ear is guided and thus sonicates the eardrum can be.

Es ist offensichtlich, daß anstelle des Anschlusses eines Hinterdem-Ohr-Hörgerätes an den Rohrkörper zum anderen auch die Möglichkeit bei den heutigen Fabrikationsmöglichkeiten besteht, daß der Rohrkörper selbst als Hörgerät ausgebildet ist. Alle erforderlichen elektrischen oder elektronischen Bauteile werden also in den Rohrkörper verlegt, der einenendes hinter dem Ohr frei endet und hier beispielsweise ein kleines Mikrophon tragen kann und der anderenendes frei im Gehörgang endet und hier im Rohrkörper oder Gehörgang den Hörer trägt. Mit dieser Anordnung wird daher das umständliche und überflüssige Hörgerät hinter dem Ohr vermieden, das nicht in allen Fällen sicher vom Ohr getragen werden kann und andererseits wird trotzdem erreicht, daß der Gehörgang nicht voll verschlossen wird.It is obvious that instead of connecting a behind-the-ear hearing aid to the tubular body to the other Possibility with today's manufacturing possibilities, that the tubular body itself is designed as a hearing aid. All necessary electrical or electronic components so laid in the tubular body, the one behind the ear ends freely and here, for example, wear a small microphone can and the other end ends freely in the ear canal and here in the tubular body or ear canal. With this arrangement is therefore the cumbersome and unnecessary hearing aid avoided behind the ear, which is not always safe from the Ear can be worn and on the other hand is still achieved that the ear canal is not completely closed.

So ist in Fig. 5 und 6 ein solcher Rohrkörper 1 dargestellt, der aus Titan besteht und sich aus drei Einzelteilen aufbaut, nämlich einem Ohrstück 12, einem Verbindungsstück 15 und einem Außenstück 14, das hinter dem Ohr mündet. Diese drei Einzelteile werden durch Verschrauben miteinander verbunden, wobei das Außenstück 14 ein Außengewinde aufweist ebenso wie das Ohrstück 12 und das eigentliche Verbindungsstück 15 mit entsprechenden Innengewindebereichen versehen ist. Diese Art der Ausbildung hat den Vorteil, daß Längenanpassungen sowohl innerhalb des Gehörganges wie auch außerhalb des Kopfes möglich sind, indem nunmehr das Außenstück 14 gegenüber dem Verbindungsstück 15 in der Länge verschoben wird ebenso wie das Ohrstück 12, das in der Länge gegenüber dem Verbindungssstück 15 verschoben werden kann.Such a tubular body 1 is shown in FIGS. 5 and 6, which consists of titanium and is composed of three individual parts, namely an earpiece 12, a connector 15 and an outer piece 14, which opens behind the ear. These three parts are connected by screwing, the Outer piece 14 has an external thread just like that Earpiece 12 and the actual connector 15 with corresponding Internal thread areas is provided. This kind the training has the advantage that length adjustments both inside the ear canal as well as outside the Head are possible by now facing the outer piece 14 the connector 15 shifted in length is just like the earpiece 12, which is opposite in length the connector 15 can be moved.

Es ist natürlich ein Bestreben, den eigentlichen Rohrkörper 1 möglichst ortsfest innerhalb der Körperöffnung festzulegen und hierzu wird vorgeschlagen, daß die Außenseite des eigentlichen Rohrkörper 1 in irgendeiner Form relativ rutschfest ausgebildet wird. Dies kann z. B. durch Gewinde erfolgen, das auf der Außenseite des in Fig. 5 dargestellten Rohrstückes 1 angeordnet wird, so daß nunmehr durch Verdrehen des gesamten Bauteiles, insbesondere des Verbindungsstückes 15, gegenüber der Körperöffnung eine Verstellung, aber auch eine Arretierung des Rohrkörpers 1 möglich ist.Of course, the actual tubular body 1 is endeavored as fixed as possible within the body opening and it is proposed that the outside of the actual The tubular body 1 is designed to be relatively non-slip in any form becomes. This can e.g. B. done by thread on the outside of the pipe section 1 shown in FIG. 5 is so that now by turning the entire component, in particular the connector 15, opposite the Body opening an adjustment, but also a locking of the Tubular body 1 is possible.

Auch kann der Rohrkörper 1 gemäß Fig. 6 mit Verdichtungen versehen sein, die dann beidseits der Körperöffnung liegen.The tubular body 1 according to FIG. 6 can also be compressed be provided, which are then on both sides of the body opening.

Schließlich zeigt Fig. 7, daß es möglich ist, in den Rohrkörper 1 ein Geräteträgerrohr 16 einzusetzen, an dem alle erforderlichen elektrischen oder elektronischen Bauteile befestigt werden können, die die eigentliche Hörhilfe bilden, die nunmehr in dem Rohrkörper 1 angeordnet ist. Das Geräteträgerrohr 16 wird durch Federlappen 17 im Rohrkörper 1 bzw. in dem Bauteil 14 federnd festgelegt, und hierbei kann außerdem vorgesehen sein, daß zwischen dem Geräteträgerrohr 16 und der Innenseite des Rohrstückes 14 ein Isolierrohr angeordnet wird, das nunmehr zu einer besseren Schallführung beiträgt.Finally, Fig. 7 shows that it is possible in the tubular body 1st to use a device support tube 16 on which all necessary electrical or electronic components are attached can, which form the actual hearing aid, which is now in the Tubular body 1 is arranged. The device support tube 16 is by spring tabs 17 in the tubular body 1 or in the component 14 resiliently fixed, and this can also be provided that between the equipment support tube 16 and the inside of the Tube piece 14 is arranged an insulating tube, which is now too contributes to better sound guidance.
