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

„Hörgerät""Hearing aid"
Die Erfindung bezieht sich auf ein Hörgerät gemäß dem Ober¬ begriff des Hauptanspruches.The invention relates to a hearing aid according to the preamble of the main claim.
Insbesondere Hinter-dem-Ohr-Hörgeräte sind in großem Um¬ fang im Einsatz, wobei die Schallübertragung über den äußeren Gehörgang zum Trommelfell erfolgt. Bei Hinter-dem-Ohr-Behind-the-ear hearing aids in particular are widely used, with sound transmission via the external auditory canal to the eardrum. Behind-the-ear
Hörgeräten wird der Schall vom Mikrophon des Hörgerätes auf¬ genommen, nach audiologischer Vorgabe verstärkt und über den galvanisch angekoppelten Hörer abgestrahlt. Am Höreraus¬ tritt befindet sich in der Regel ein Hörwinkel oberhalb der Ohr- muschel 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.Hearing aids, the sound is picked up by the microphone of the hearing aid, amplified according to audiological requirements and emitted via the galvanically coupled receiver. At the listener outlet there is usually a hearing angle above the ear cup for the reception of a sound tube, which leads into the external auditory canal by means of an otoplastic. The sound amplified by the hearing aid thus radiates through the sound tube and the sound channel above and then in front of the ear cup via the otoplastic directly into the ear canal and thus onto the eardrum.
Nachteilig bei diesen bekannten Hörgeräten wurde aber emp¬ funden, daß die Schallführung, d. h. also der Schallschlauch, immer sichtbar vom Hinter-dem-Ohr-Hörgerät vor der Ohrmu- schel in den äußeren Gehörgang verläuft. Es sind auch bereits sogenannte In-dem-Ohr-Horgerate vorge¬ schlagen worden, die diesen Nachteil nicht aufweisen, insbe¬ sondere dann, wenn die sichtbare Flache des In-dem-Ohr-Hor- gerates der Hautfarbe des jeweiligen Patienten angepaßt ist Nachteilig bei diesen Anordnungen ist aber, daß der Gehorgang verschlossen wird, also nicht mehr offen ist, was von vielen Pa¬ tienten als unangenehm empfunden wirdA disadvantage of these known hearing aids, however, was found that the sound guide, ie the sound tube, always runs from the behind-the-ear hearing device in front of the ear cup into the outer auditory canal. So-called in-the-ear hearing aids have also been proposed which do not have this disadvantage, in particular when the visible surface of the in-the-ear hearing aid is adapted to the skin color of the respective patient With these arrangements, however, it is that the auditory canal is closed, that is, it is no longer open, which many patients find unpleasant
Der Erfindung liegt die Aufgabe zugrunde, die bekannten Horge- rate dahingehend zu verbessern, daß eine möglichst unsicht¬ bare Horgerateversorgung erfolgen kann, gleichzeitig aber auch die Schallubertragung verbessert wird und der Gehorgang nicht vollständig verschlossen wirdThe object of the invention is to improve the known hearing rate in such a way that the hearing device can be supplied as invisibly as possible, but at the same time the sound transmission is improved and the auditory canal is not completely closed
Diese der Erfindung zugrundeliegende Aufgabe wird durch denThis object underlying the invention is achieved by the
Vorschlag gelost, einen nach außen hinter dem Ohr zwischen dem Schläfenbein im Bereich des Pars petrosa und der Ohr¬ muschel einenendes und durch eine Öffnung im äußeren Ohr fuhrenden, im Gehorgang anderenendes mundenden Rohrkor- per vorzusehen, der im Bereich des freien Endes z B hinter dem Ohr den Schall aufnimmt und am gehorgangseitigen Ende das Trommelfell beschalltProposal solved to provide a tubular body that ends outward behind the ear between the temporal bone in the area of the pars petrosa and the auricle and leads through an opening in the outer ear and ends in the auditory canal that ends in the area of the free end, for example, behind picks up sound from the ear and sonicates the eardrum at the end of the ear canal
Vorteilhafte Ausgestaltungen sind in den Unteranspruchen er- läutertAdvantageous configurations are explained in the subclaims
So wird einmal vorgeschlagen, daß der Rohrkorper an seinem freien Ende an die Schallaustπttsoffnung eines Hinter-dem-Ohr- Horgerates anschließbar ist und zum anderen wird vorgeschla- gen, daß der Rohrkorper selbst als Hörgerät ausgebildet ist und im Bereich des freien Endes das Mikrophon und am gehorgang¬ seitigen Ende den Hörer tragt Hierbei ist es möglich, daß der Rohrkorper bis zum oberen Ansatz der Ohrmuschel verlängert ist und sich nach vorne öffnet und hier das Mikrophon tragt Auch der Anschluß des Rohrkorpers an einen Ohrring ist mög¬ lich, der dann mit dem Mikrophon versehen wirdThus, it is proposed that the tubular body can be connected at its free end to the sound opening of a behind-the-ear hearing aid, and on the other hand it is proposed that the tubular body itself be designed as a hearing device and in the area of the free end the microphone and carries the handset at the end of the ear canal. It is possible for the tubular body to be extended to the upper attachment of the pinna and to open to the front and carry the microphone here It is also possible to connect the tubular body to an earring, which is then provided with the microphone
Wird der Rohrkorper an ein Hinter-dem-Ohr-Horgerat ange- schlössen, ist es wichtig, daß ein leichter, aber dichter Anschluß möglich ist, und so wird vorgeschlagen, eine zwischen dem Schallaustrittstutzen des Hörgerätes und einer Schalleitung vor¬ gesehene Dichtmuffe einzusetzen, die eine nahezu spannungs¬ lose, aber schallwellendichte Verbindung der Wandung des Schallaustπttsstutzens mit der Wandung der Schalleitung z B des retroauπkularen Rohrkorpers ermöglichtIf the tubular body is connected to a behind-the-ear hearing device, it is important that a light but tight connection is possible, and so it is proposed to use a sealing sleeve provided between the sound outlet connector of the hearing aid and a formwork line. which enables an almost stress-free, but sound wave-tight connection of the wall of the soundproofing nozzle to the wall of the sound conductor, for example of the retro-tubular pipe body
Der Rohrkorper kann aus Kunststoff bestehen, wird aber vor¬ zugsweise gemäß der Erfindung aus Titan hergestellt, womit er die erforderliche Festigkeit und Gewebevertraghchkeit auf¬ weist Wird der Rohrkorper aus Titan hergestellt, wird er vor¬ zugsweise dreiteilig ausgebildet und besteht aus einem Ohr¬ stuck, einem Außenstuck und einem Verbindungskorper, wobei das Ohrstuck und das Außenstuck in den Verbindungskorper eingeschraubt werden können, so daß dadurch gleichzeitig auchThe tubular body can be made of plastic, but is preferably made of titanium according to the invention, with which it has the required strength and tissue compatibility. If the tubular body is made of titanium, it is preferably made in three parts and consists of an ear piece , an outer piece and a connecting body, wherein the ear piece and the outer piece can be screwed into the connecting body, so that at the same time as a result
Langenverstellungen des eigentlichen Rohrkorpers möglich Length adjustments of the actual tube body possible
Insbesondere dann, wenn der Rohrkorper aus Titan besteht, er- scheint es vorteilhaft, dafür Sorge zu tragen, daß eine sichereIn particular, if the tubular body is made of titanium, it seems advantageous to ensure that it is secure
Lage des Rohrkorpers in der Korperoffnung gewährleistet ist, was vorzugsweise dadurch erreicht wird, daß die Außenseite des Rohrkorpers rutschfest gestaltet wird Dies kann einmal durch eine entsprechende Aufrauhung oder partielle Verdich- tungen der Außenseite erfolgen, kann aber in gleicher Weise auch dadurch erfolgen, daß auf der Außenseite eine Art Gewin¬ de angebracht wird, das dann auch die Möglichkeit gibt, ohne Hautverletzungen den Rohrkorper in der Korperoffnung zu ver¬ stellen Natürlich können diese Maßnahmen auch dann vorge- sehen werden, wenn der Rohrkorper aus Kunststoff besteht Mit anderen Worten ausgedrückt wird gemäß der vorliegenden Erfindung vorgeschlagen, daß ein Hörgerät konzipiert wird, das mit einer Schallüberleitungsöffnung hinter dem Ohr versehen wird, vorzugsweise zwischen Schläfenbein im Bereich des Pars petrosa und Ohrmuschel, so daß die Schallführung nicht sicht¬ bar von hinten durch eine Öffnung im äußeren Ohr, d. h. eine Körperöffnung in den Gehörgang geführt wird und somit das Trommelfell beschallt werden kann.Position of the tube body in the body opening is ensured, which is preferably achieved by making the outside of the tube body non-slip. This can be done by appropriate roughening or partial compression of the outside, but can also be done in the same way that a kind of thread is attached to the outside, which then also gives the possibility of adjusting the tube body in the body opening without skin injuries. Of course, these measures can also be provided if the tube body is made of plastic In other words, it is proposed according to the present invention that a hearing aid is designed which is provided with a sound transmission opening behind the ear, preferably between the temporal bone in the area of the pars petrosa and the pinna, so that the sound guidance is not visible from behind through a Opening in the outer ear, ie a body opening is inserted into the ear canal and the eardrum can be sonicated.
Es ist offensichtlich, daß anstelle des Anschlusses eines Hinter- dem-Ohr-Hörgerätes an den Rohrkörper zum anderen auch die Möglichkeit bei den heutigen Fabrikationsmöglichkeiten besteht, daß der Rohrkörper selbst als Hörgerät ausgebildet ist. Alle er- forderlichen 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 An- Ordnung 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 er¬ reicht, daß der Gehörgang nicht voll verschlossen wird.It is obvious that instead of connecting a behind-the-ear hearing device to the tubular body on the other hand, there is also the possibility with today's manufacturing possibilities that the tubular body itself is designed as a hearing device. All the necessary electrical or electronic components are thus laid in the tubular body, which ends at one end behind the ear and can, for example, carry a small microphone here and ends at the other end in the ear canal and carries the listener here in the tubular body or auditory canal. With this arrangement, the cumbersome and superfluous hearing aid behind the ear is avoided, which cannot always be worn safely by the ear, and on the other hand it is achieved that the auditory canal is not fully closed.
Ausführungsbeispiele der Erfindung werden nachfolgend an¬ hand der Zeichnungen erläutert. Die Zeichnungen zeigen dabei inExemplary embodiments of the invention are explained below with reference to the drawings. The drawings show in
Fig. 1 eine Schnittzeichnung durch das Ohr von vorne gesehen, das den im Gehörgang liegenden Rohr körper verdeutlicht, in Fig. 2 eine abgeänderte Ausführungsform gemäß Fig. 1 , bei der der im Gehörgang liegende Rohrkörper oben am oberen Ansatz der Ohrmuschel nach außen hin mündet, in Fig. 3 eine Schnittzeichnung - von hinter dem Ohr her ge sehen - die die Lage des Rohrkörpers und dessen Mündung verdeutlicht, inFig. 1 is a sectional view through the ear seen from the front, which illustrates the tube body lying in the ear canal, in Fig. 2 shows a modified embodiment according to FIG. 1, in which the tube body lying in the ear canal opens out at the top of the upper attachment of the ear cup , in Fig. 3 is a sectional drawing - seen from behind the ear ge - which illustrates the position of the tubular body and its mouth, in

In den Zeichnungen ist mit 1 ein Rohrkörper bezeichnet, desen eines Ende im Gehörgang 4 und dessen anderes Ende zwi¬ schen der Rückseite der Ohrmuschel 7 und dem Schläfenbein mündet. Hierbei kann diese als Schalleintrittsöffnung 2 (Fig. 2 und 3) ausgebildete Mündung gleichzeitig als Mikrophon 3 aus- gebildet sein. Innerhalb des Rohrkörpers 1 liegt am anderenIn the drawings, 1 denotes a tubular body, one end of which opens into the auditory canal 4 and the other end of which opens between the back of the ear cup 7 and the temporal bone. This mouth, which is designed as a sound inlet opening 2 (FIGS. 2 and 3), can at the same time be designed as a microphone 3. Within the tubular body 1 lies on the other
Ende, das frei im Gehörgang 4 mündet, gemäß Fig. 3 ein Hörer 6 und es sind die weiteren elektrischen Bauteile 5 erkennbar.3, a receiver 6 and the further electrical components 5 can be seen.
Bei der Darstellung gemäß Fig. 1 ist das Ohr von vorne ge- zeichnet und es ist der Gehörgang 4 erkennbar, in welchem der1 the ear is drawn from the front and the auditory canal 4 can be seen in which the
Rohrkörper 1 liegt, der nunmehr nach Durchdringen einer Kör¬ peröffnung frei hinter dem Ohr zwischen Schläfenbein und Ohrmuschel mündet.Pipe body 1 is located, which now opens freely behind the ear between the temporal bone and auricle after penetrating a body opening.
Bei der Ausführungsform gemäß Fig. 2 ist der Rohrkörper 1 nach oben hin verlängert und mündet nunmehr am oberen An¬ satz der Ohrmuschel 7 und ist dort mit einem Mikrophon 3 aus¬ gerüstet, so daß die Aufnahme der Schallwellen von vorne er¬ folgen kann.In the embodiment according to FIG. 2, the tubular body 1 is extended upwards and now opens at the upper attachment of the ear cup 7 and is equipped there with a microphone 3 so that the sound waves can be picked up from the front.
In allen drei Darstellungen gemäß den Fig. 1 bis 3 ist deutlich erkennbar, daß der Rohrkörper 1 von hinten durch eine Öffnung im äußeren Ohr in den Gehörgang 4 führt. Hierdurch wird auf jeden Fall erreicht, daß von außen nicht die Ohrmuschel 7 über einen Schallschlauch umgangen werden muß, wobei dieserIn all three representations according to FIGS. 1 to 3 it can be clearly seen that the tubular body 1 leads into the auditory canal 4 from behind through an opening in the outer ear. In this way it is achieved in any case that the outer ear 7 does not have to be bypassed via a sound tube, this
Schallschlauch auch üblicherweise sichtbar ist. Bei der Darstellung in Fig. 4 ist ein Hinter-dem-Ohr-Hörgerät 11 erkennbar, das mit einem Hörwinkel, d. h. einem Schallaus¬ trittsstutzen 8 ausgerüstet ist. An diesen Schallaustrittsstutzen 8 schließt eine Schalleitung 9 an, die als gesondertes Bauteil ausgebildet sein kann oder aber auch direkt durch den Rohr¬ körper 1 gebildet werden kann. Entscheidend bei dieser Darstel¬ lung ist der Anschluß der Schalleitung 9 oder des Rohrkörpers 1 an den Schallaustrittsstutzen 8, wobei der Schallaustrittsstutzen 8 mit einer Dichtmuffe 10 versehen ist, die eine nahezu span¬ nungslose, aber schallwellendichte Verbindung der Wandung des Schallaustrittsstutzens 8 mit der Wandung der retroaurikulä- ren Schalleitung 9 ermöglicht, wobei diese Dichtmuffe 10 an der Außenseite des Schallaustrittsstutzens 8 vorgesehen ist und damit innerhalb der Schalleitung 9 oder des Rohrkörpers 1 liegt.Sound tube is also usually visible. 4, a behind-the-ear hearing device 11 can be seen which is equipped with a hearing angle, ie a sound outlet 8. This sound outlet connection 8 is followed by a formwork line 9, which can be designed as a separate component or can also be formed directly by the tubular body 1. The decisive factor in this illustration is the connection of the formwork line 9 or the tubular body 1 to the sound outlet connector 8, the sound outlet connector 8 being provided with a sealing sleeve 10 which provides an almost stress-free but sound wave-tight connection of the wall of the sound outlet connector 8 to the wall of the retro-auricular formwork line 9, this sealing sleeve 10 being provided on the outside of the sound outlet connector 8 and thus lying within the formwork line 9 or the tubular body 1.
Der eigentliche Rohrkörper 1 kann aus Kunststoff bestehen, aber auch aus Metall gefertigt werden, dann vorzugsweise aus Titan, das besonders gewebefreundlich ist.The actual tubular body 1 can consist of plastic, but can also be made of metal, then preferably of titanium, which is particularly tissue-friendly.
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 Au¬ ßenstück 14, das hinter dem Ohr mündet. Diese drei Einzelteile werden durch Verschrauben miteinander verbunden, wobei dasSuch 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 connecting piece 15 and an outer piece 14 which opens behind the ear. These three individual parts are connected by screwing, the
Außenstück 14 ein Außengewinde aufweist ebenso wie das Ohrstück 12 und das eigentliche Verbindungsstück 15 mit ent¬ sprechenden Innengewindebereichen versehen ist. Diese Art der Ausbildung hat den Vorteil, daß Längenanpassungen so- wohl innerhalb des Gehörganges wie auch außerhalb des Ohres möglich sind, indem nunmehr das Außenstück 14 gegenüber dem Verbindungsstück 15 in der Länge verschoben wird eben¬ so wie das Ohrstück 12, das in der Länge gegenüber dem Ver- bindungssstück 15 verschoben werden kann. 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 Au¬ ßenseite des in Fig. 5 dargestellten Rohrstückes 1 angeordnet wird, so daß nunmehr durch Verdrehen des gesamten Bautei¬ les, insbesondere des Verbindungsstückes 15, gegenüber der Körperöffnung eine Verstellung, aber auch eine Arretierung des Rohrkörpers 1 möglich ist.Outer piece 14 has an external thread, just as the ear piece 12 and the actual connecting piece 15 are provided with corresponding internal thread areas. This type of design has the advantage that length adjustments are possible both within the auditory canal and outside the ear, in that the outer piece 14 is now displaced in length relative to the connecting piece 15, just like the ear piece 12, which is in length can be moved relative to the connecting piece 15. It is of course an effort to fix the actual tubular body 1 as stationary as possible within the body opening and for this purpose it is proposed that the outside of the actual tubular body 1 be designed to be relatively non-slip in any form. This can e.g. B. by thread, which is arranged on the outside of the pipe section 1 shown in FIG. 5, so that now by turning the entire component, in particular the connecting piece 15, relative to 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 provided with compressions which then lie 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 das eigentliche Hörgerät bilden, das 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 nun¬ mehr zu einer besseren Schallführung beiträgt. Finally, FIG. 7 shows that it is possible to insert a device carrier tube 16 into the tubular body 1, to which all the necessary electrical or electronic components can be attached, which form the actual hearing aid, which is now arranged in the tubular body 1. The device carrier tube 16 is resiliently fixed by spring tabs 17 in the tubular body 1 or in the component 14, and it can also be provided that an insulating tube is arranged between the device carrier tube 16 and the inside of the tube piece 14, which now leads to better sound transmission contributes.
