Abstract

The invention relates to an otoplastic for production of behind-the-ear hearing aids. Said hearing aid comprises a preferably flexible signal conductor, such as e.g. an acoustic tube (28) which can be positioned in the auditory canal, whereby the otoplastic matches the individual anatomy of the patient and its locating part is essentially in the form of a clip, which, at least partly arched, follows the outer edge (36) of the cavum conchae (22). A branch (32) which follows the edge of the cavum conchae transforms, above the antitragus(30), into a bent crosspiece (34) which traverses the cavum conchae and runs in the direction of the porus acusticus externus. The end section (40) of said crosspiece (34) lies in the upper section of the auditory canal (26) and widens to accept the signal conductor (42).

Otoplastik für Hinter-dem-Ohr (HdO)-HörqeräteOtoplasty for behind-the-ear (BTE) hearing aids
Die Erfindung betrifft ein Ohrpassstück bzw. eine Otoplastik für Hinter-dem-Ohr (HdO) -Geräte auf dem Gebiet der Hörakustik. Diese Geräte werden oftmals auch als sogenannte HdO-Secret-Ears (SE) bezeichnet. Dabei findet ein verhältnismässig kurzer Schal Ischlauch Anwendung, mit dem es gelingt, die Reibungsverluste insbesondere des hochfrequenten Schal lanteils merklich zu reduzieren.The invention relates to an earmold or an earmold for behind-the-ear (BTE) devices in the field of hearing acoustics. These devices are often referred to as BTE Secret Ears (SE). Here, a relatively short scarf hose is used, with which it is possible to significantly reduce the frictional losses, in particular of the high-frequency scarf component.
Der Schal Ischlauch muss allerdings exakt im bzw. am Gehörgang positioniert werden, wozu regelmässig ein Ohrpassstück bzw. eine Otoplastik Verwendung findet, die individuell an die menschliche Anatomie des Ohres des zu behandelnden Patienten angepasst wird. Es haben sich bis heute verschiedene Formen der Otoplastik durchgesetzt, wobei einige, nämlich die sogenannten "offenen" HdO- Otoplastiken besonders bevorzugt werden, um den Gehörgang möglichst minimal durch einen "Fremdkörper" zu verlegen bzw. bereichsweise zu verschli essen. Diese "offene" HdO-Versorgung hat dabei den Vorteil, dass die noch vorhandene Aufnahmefähigkeit des Gehörs in ihrer Natürlichkeit so gering wie möglich beeinträchtigt wi rd .However, the scarf Ischlauch must be positioned exactly in or on the ear canal, for which purpose an earmold or an earmold is regularly used, which is individually adapted to the human anatomy of the ear of the patient to be treated. To date, various forms of otoplastic have prevailed, with some, namely the so-called "open" BTE earmolds, being particularly preferred in order to cover the ear canal as little as possible with a "foreign body" or to wear it in areas. This "open" BTE supply has the advantage that the natural hearing ability of the hearing is impaired as little as possible.
Bekannte einschlägige Otoplastiken sind als "SE-Schalenform, SE-Spangenfor oder SE-Krallenform" bekannt (siehe Ulrich Voogdt: Otoplastik - Die individuelle Otoplastik zur Hörgeräte- Versorgung..., Band 2 der wissenschaftlichen Fachbuchreihe "Akademie für Hörgeräte-Akustik", edian-Verlag von Killisch-Horn GmbH, 1993). Eine Abwandlung dieser gängigen Otoplastiken stellt die "offene" Lösung dar. Allen Varianten ist jedoch gemeinsam, dass es häufig nicht gelingt die hörtechnische Korrektur so natürlich wie möglich abzubilden. Aufgabe der Erfindung ist es deshalb, eine Otoplastik für "offene" HdO-Versorgungen, für CI-Komponenten (Cochlea Implant- Mikrofon-Systeme bzw. CI-HdO-Prozessoren) oder HdO-Tinnitus- Systeme zu schaffen, die sich nicht nur durch ein minimalisiertes Fremdkörpergefühl und guten Tragekomfort, sondern vorrangig dadurch auszeichnet, dass die natürliche Schall Verarbeitung im menschlichen Ohr so unverfälscht wie möglich genutzt werden kann, um dadurch ein Höchstmass an hörakustischer Korrektur und Natürlichkeit des Hörempfindens zu gewährleisten.Known relevant otoplastics are known as "SE shell shape, SE clasp shape or SE claw shape" (see Ulrich Voogdt: Otoplastik - The Individual Otoplasty for Hearing Aid Supply ..., Volume 2 of the scientific book series "Academy for Hearing Aid Acoustics", edian-Verlag von Killisch-Horn GmbH, 1993). A modification of these common earmolds is the "open" solution. However, all variants have in common that it is often not possible to reproduce the hearing correction as naturally as possible. The object of the invention is therefore to provide an earmold for "open" BTE supplies, for CI components (cochlear implant microphone systems or CI BTE processors) or BTE tinnitus systems that are not only characterized by a minimized foreign body sensation and good wearing comfort, but primarily characterized by the fact that the natural sound processing in the human ear can be used as pristine as possible, in order to ensure the highest level of auditory acoustic correction and naturalness of the hearing sensation.
Diese Aufgabe wird durch eine Otoplastik nach Anspruch 1 bzw. nach Anspruch 5 gelöst.This object is achieved by an otoplastic according to claim 1 or claim 5.
Mit der erfindungsgemässen Otoplastik nach Anspruch 1 gelingt es, in bislang nicht erreichtem Maße, den Gehörgang an den entscheidenden Stellen offen zu halten. Die Erfindung beruht auf der Überlegung, dass die Natürlichkeit des Hörempfindens einerseits und die Effektivität der hörakustischen Korrektur andererseits erheblich durch die anatomisch vorgegebenen, natürlichen Resonanzverhältnisse im Gehörgang unter Einschluss der Ohrmuschel beeinflusst werden. Mit der erfindungsgemässen Gestaltung der Otoplastik bleibt die natürliche Resonanz weitgehend unbeeinflusst, selbst dann wenn der Gehörgang sehr eng ist. Dabei ergeben sich die zusätzlichen Vorteile, dass der Tragekomfort (materialfreier Bereich im Bereich der Crus-Helicis; kein Wärmestau) äusserst gut ist, dass die Otoplastik sehr wenig Material benötigt und damit auch kosmetische Vorzüge hat, und dass die akustische Ankopplung zur Frequenz- und Dynamik-Beeinflussung komplikationsfreier erfolgen kann.With the earmold according to the invention, it is possible to keep the auditory canal open at the crucial points to an extent not previously achieved. The invention is based on the consideration that the naturalness of the hearing sensation on the one hand and the effectiveness of the auditory acoustic correction on the other hand are significantly influenced by the anatomically predetermined, natural resonance conditions in the auditory canal, including the auricle. With the design of the otoplastic according to the invention, the natural resonance remains largely unaffected, even if the ear canal is very narrow. This has the additional advantages that the wearing comfort (material-free area in the area of the crus-helicis; no heat build-up) is extremely good, that the otoplastic requires very little material and thus also has cosmetic advantages, and that the acoustic coupling for frequency and Dynamics can be influenced without complications.
Obwohl die erfindungsgemässe Otoplastik weniger Raum einnimmt, kann sie die den Schallschlauch stabilisierende Funktion zuverlässig erfüllen, indem die Ankopplung des Schallschlauchs an das HdO-Gerät zur Stabilisierung genutzt wird. Es zeigt sich, dass der Abstützkörper der Otoplastik trotz der verringerten Kontaktfläche mit der Cavum conchae so stabil positioniert ist, dass der Endabschnitt der Otoplastik-Traverse gemäss der Weiterbildung in Anspruch 2 einen Gehörgangszapfen tragen kann, wodurch eine bessere Abstützung im Gehörgang verwirklicht werden kann.Although the otoplastic according to the invention takes up less space, it can reliably perform the function stabilizing the sound tube by using the coupling of the sound tube to the BTE device for stabilization. It turns out that the support body of the otoplastic, despite the reduced contact area with the cavum conchae, is positioned so stably that the end section of the otoplastic crossmember can carry an auditory canal pin, whereby better support in the auditory canal can be achieved.
Die oben angegebene Aufgabe wird entsprechend einer zweiten Alternative gemäss Anspruch 5 dadurch gelöst, dass die Otoplastik erstmalig an einer Stelle der Ohrmuschel positioniert wird, die vollständig ausserhalb der Cavum conchae liegt. Es hat sich überraschenderweise gezeigt, dass es bei Positionierung des haltgebenden Teils der Otoplastik in der Cymba ohne weiteres gelingt, im Zusammenwirken mit der Eigenstabilität des flexiblen Signall ei ters bzw. des Schal Ischlauchs, diesen exakt und reproduzierbar im Gehörgang zu positionieren, der erfindungsgemäss von keinem Otoplastik-Bauteil mehr verlegt wird. Damit eignet sich diese Otoplastik in besonderem Maß neben "offenen" Standard- Applikationen für Anwendungsfälle bei Kindern mit einohriger Taubheit oder z.B. bei normal hörenden Schülern mit einer sogenannten Lese-Rechtschreibe-Schwäche in Verbindung mit sogenannten FM (Frequenzmodulation) -Systemen, bei denen das Sprechsignal des Lehrers über Mikrofon und eine Mikroport-Anlage in den Gehörgang des hörbehinderten Kindes eingespeist wird. Speziell in diesem Fall kommt es ganz besonders auf die Ausnützung der natürlichen Gehörgang-Resonanz an, was durch die erfindungsgemässe Otoplastik in bislang nicht erzieltem Maße gegeben ist. Aufgrund der verbesserten Randbedingungen wird es darüber hinaus einfacher, die akustische Ankopplung des Hörgeräts zur Frequenz- und Dynamik-Beeinflussung vorzunehmen, so dass sich die erfindungsgemässe Otoplastik auch für den Medieneinsatz, wie z.B. bei TV-Live-Interviews als eine Art von "offenem In-Ear- Monitoring" anbietet, wobei in diesem Fall beispielsweise eine Simultan-Übersetzung oder das Sprechsignal eines Suffleurs unter möglichst natürlichen Bedingungen in den Gehörgang eingespeist werden.According to a second alternative, the above-mentioned object is achieved in that the otoplastic is positioned for the first time at a location on the ear that lies completely outside the cavum conchae. Surprisingly, it has been shown that when the holding part of the otoplastic is positioned in the cymba, it is possible, in cooperation with the inherent stability of the flexible signal signal or the scarf tube, to position it precisely and reproducibly in the auditory canal, which according to the invention by no more earmold components are laid. This otoplastic is particularly suitable in addition to "open" standard applications for applications in children with single-eared deafness or, for example, in pupils with normal hearing with a so-called reading-spelling weakness in connection with so-called FM (frequency modulation) systems, in which the The teacher's speech signal is fed into the auditory canal of the hearing-impaired child via a microphone and a microport system. In this case in particular, it is particularly important to utilize the natural auditory canal resonance, which has not been achieved to date to the extent achieved by the otoplastic according to the invention. Due to the improved boundary conditions, it is also easier to make the acoustic coupling of the hearing aid to influence the frequency and dynamics, so that the otoplastic according to the invention can also be used as a kind of "open in" for media use, such as in TV live interviews -Ear- Monitoring "offers, in which case, for example, a simultaneous translation or the speech signal of a suffleur under conditions that are as natural as possible are fed into the ear canal.
Ein besonderer Vorzug der Otoplastik nach Anspruch 5 ist auch darin zu sehen, dass bezüglich der Gestaltung des den Rand der Ohrmuschel bogenförmig übergreifenden Bügels eine grosse Freiheit besteht, was wiederum zur zusätzlichen Stabilisierung der Otoplastik genutzt werden kann. Die Weiterbildung nach Anspruch 6 geht in diese Richtung.A particular advantage of the otoplastic according to claim 5 is also to be seen in the fact that there is great freedom with regard to the design of the bracket which extends over the edge of the ear cup in the form of an arc, which in turn can be used to additionally stabilize the otoplastic. The development according to claim 6 goes in this direction.
Wenn sich der haltgebende Hauptkörper der Otoplastik gemäss Anspruch 7 in den Bereich der Crus Anthelicis hinein erstreckt, wird die Stabilisierung des Hauptkörpers weiter verbessert, wodurch es gelingt, die Grosse des Hauptkörpers weiter zu verringern. Dies verbessert gleichzeitig den Tragekomfort und hat auch hinsichtlich der Kosmetik Vorteile.If the supporting main body of the otoplastic extends into the area of the crus anthelicis, the stabilization of the main body is further improved, whereby it is possible to further reduce the size of the main body. At the same time, this improves wearing comfort and also has advantages in terms of cosmetics.
Auch diese Ausführungsform hat ebenso wie die Ausführungsform nach Anspruch 1 den Vorzug dass sie bei speziellen Sonder- Applikationen, wie z.B. bei sehr engem Gehörgang oder starkerThis embodiment too, like the embodiment according to claim 1, has the advantage that it can be used in special special applications, such as with very narrow ear canal or strong
Terminal -Behaarung im Gehörgang oder sonstigen Anomalien derTerminal hair in the ear canal or other abnormalities of the
Ohranatomie ohne Komplikationen einsetzbar ist.Ear anatomy can be used without complications.
Weiterbildungen der Erfindung sind Gegenstand der übrigen Unteransprüche.Further developments of the invention are the subject of the remaining subclaims.

In Fig. 1 ist mit dem Bezugszeichen 20 eine Otoplastik für ein HdO-Gerät gezeigt, die in die mit 22 bezeichnete Cavum conchae eingesetzt ist. Mit dem Bezugszeichen 24 ist die Crus helicis bezeichnet und mit dem Bezugszeichen 26 der Gehörgang bzw. Meatus acusticus externus.In Fig. 1, the reference numeral 20 shows an earmold for a BTE device, which is inserted into the 22 designated Cavum conchae. The reference numeral 24 denotes the crus helicis and the reference numeral 26 the auditory canal or external acoustic meatus.
Die Otoplastik dient zur Stabilisierung eines zum nicht gezeigten HdO-Gerät führenden Schall schlauchs 28, der in den Gehörgang mündet. Zu diesem Zweck ist die Otoplastik beispielsweise nach einem Abdruckverfahren individuell der Anatomie des Patienten angepasst. Sie hat im wesentlichen die Form einer Spange mit zwei Schenkeln 32, 34. Der erste Schenkel erstreckt sich bogenförmig entlang des äusseren Randes 36 der Cavum conchae 22 bis zu einem Punkt oberhalb des mit 30 bezeichneten Antitragus. Von dort verläuft die Otoplastik abgewinkelt nach oben über einen die Cavum conchae durchquerenden zweiten Schenkel, der im folgenden als Traversenabschnitt 34 bezeichnet wird. Der Traversenabschnitt verläuft in Richtung Porus acusticus externus 38 und verbreitert sich dort zu einem Endabschnitt 40, der zur Aufnahme des Signalleiters, im gezeigten Fall, eines Schal Ischlauch-Winkel Stücks 42 dient.The otoplastic serves to stabilize a sound tube 28 leading to the BTE device, not shown, which opens into the ear canal. For this purpose, the otoplastic is individually adapted to the patient's anatomy, for example using an impression method. It has essentially the form a clip with two legs 32, 34. The first leg extends in an arc along the outer edge 36 of the cavum conchae 22 to a point above the antitragus designated 30. From there, the otoplastic runs angled upward over a second leg that crosses the cavum conchae and is referred to below as the cross-piece section 34. The truss section runs in the direction of the porus acoustic external 38 and widens there to an end section 40, which serves to receive the signal conductor, in the case shown, of a scarf Ischlauch angle piece 42.
Wie aus Fig. 2 ersichtlich, geht der Endabschnitt 40 in einen Gehörgangszapfen 44 über, in dem eine Bohrung (gestrichelt gezeichnet) 46 ausgebildet ist.As can be seen from FIG. 2, the end section 40 merges into an auditory canal pin 44, in which a bore 46 (shown in dashed lines) is formed.
Man erkennt aus der Darstellung, dass die Otoplastik denIt can be seen from the illustration that the earmould
Gehörgang 26 nur unwesentlich verdeckt, so dass die natürlicheThe ear canal 26 is only slightly obscured, so that the natural
Gehörgang/Ohrmuschel -Resonanz aufrechterhalten bleibt. Eine zusätzliche Stabilisierung der Otoplastik 20 erfolgt durch den Schallschlauch 28, der mit dem Winkelstück 42 fest verbunden ist.Ear canal / pinna resonance is maintained. The earmold 20 is additionally stabilized by the sound tube 28, which is firmly connected to the angle piece 42.
In den Figuren 3 und 4, die eine aus Kunststoff gefertigte Otoplastik nach den Figuren 1 und 2 darstellen ist gut die filigrane Struktur erkennbar, die dennoch in der Cavum conchae stabil fixierbar ist.FIGS. 3 and 4, which represent an otoplastic made of plastic according to FIGS. 1 and 2, clearly show the filigree structure, which can nevertheless be stably fixed in the cavum conchae.
Den kosmetischen Aspekt der erfindungsgemässen Otoplastik erkennt man am besten aus der Figur 5, in der die sichtbare Fläche der Otoplastik 20 schraffiert dargestellt ist. Es liegt auf der Hand, dass die erfindungsgemässe Formgebung so beschaffen ist, dass sie das natürliche Erscheinungsbild der Ohrmuschel quasi nicht beeinträchtigt.The cosmetic aspect of the otoplastic according to the invention can best be seen from FIG. 5, in which the visible surface of the otoplastic 20 is shown hatched. It is obvious that the shape according to the invention is such that it practically does not impair the natural appearance of the auricle.
In den Figuren 6 bis 11 sind weitere Ausführungsformen der erfindungsgemässen Otoplastik nach Anspruch 5 gezeigt. Die Otoplastik, die wiederum - wie auch in den Figuren 1 und 2 - schraffiert hervorgehoben ist, ist mit dem Bezugszeichen 120 bezeichnet. Sie ist derart angeordnet, dass die Cavum conchae vollständig frei bleibt. Stattdessen ist die Otoplastik im Bereich der Cymba conchae 50, im gezeigten Fall mit einer Erstreckung in den Bereich der Crus anthelicis 52, 54 angeordnet.FIGS. 6 to 11 show further embodiments of the otoplastic according to the invention as claimed in claim 5. The otoplastic, which in turn - as in FIGS. 1 and 2 - is highlighted by hatching, is identified by reference numeral 120. It is arranged in such a way that the cavum conchae remains completely free. Instead, the otoplastic is arranged in the area of the cymba conchae 50, in the case shown with an extension into the area of the crus anthelicis 52, 54.
Die Otoplastik ist wiederum der Anatomie des Patienten individuell angepasst und sie besteht im wesentlichen aus zwei Komponenten, nämlich einem haltgebenden Teil 156, der formschlüssig versenkt in der Cymba conchae 50 aufgenommen ist, und einem den Rand 58 der Ohrmuschel bogenförmig übergreifenden Hügel 160, der an seinem Ende die Halterung für den flexiblen Schallschlauch 128 ausbildet. Der Schallschlauch 128 ist - wie in Fig. 7 gezeigt - abgewinkelt in das Innere des Gehörgangs 26 geführt und kann dort beispielsweise einen sogenannten Cerumdefender 162 tragen.The otoplastic is in turn individually adapted to the patient's anatomy and essentially consists of two components, namely a support part 156, which is received in a form-fitting manner in the cymba conchae 50, and a hill 160, which overlaps the edge 58 of the auricle in an arcuate manner forms the holder for the flexible sound tube 128 at its end. As shown in FIG. 7, the sound tube 128 is angled into the interior of the auditory canal 26 and can, for example, carry a so-called cerium defender 162 there.
Diese Ausführungsform der Otoplastik hat ein noch kleineres Bauvolumen als die Otoplastik nach den Figuren 1 bis 5 und sie lässt - wie der Fig. 7 entnehmbar ist - den Gehörgang quasi unbeeinflusst.This embodiment of the otoplastic has an even smaller construction volume than the otoplastic according to FIGS. 1 to 5 and, as can be seen in FIG. 7, it leaves the auditory canal virtually unaffected.
In den Figuren 8 und 9 ist eine in der Praxis eingesetzte Otoplastik vergrössert wiedergegeben. Man erkennt deutlich die mehrfach gekrümmte Oberflächengestaltung des Hauptkörpers, die für den passgenauen und verschiebesicheren Sitz in der Cymba conchae verantwortlich ist. Die Ausführungsform nach Fig. 8, 9 ist für einen Patienten hergestellt worden, bei dem die Cymba conchae ausgesprochen großvolumig ausgebildet ist.FIGS. 8 and 9 show an enlarged otoplastic used in practice. You can clearly see the multi-curved surface design of the main body, which is responsible for the precisely fitting and secure fit in the cymba conchae. The embodiment according to FIGS. 8, 9 has been produced for a patient in whom the cymba conchae is of a particularly large volume.
In den Figuren 10 und 11 ist eine weitere Ausführungsform gezeigt, die bei einem Patienten mit wesentlich kleinerer Cymba conchae angewendet wurde. Die mit 220 bezeichnete Otoplastik hat einen wesentlich kleineren Hauptkörper 256, der allerdings wiederum mehrfach räumlich gekrümmt ist, so dass die erforderliche Hinterschneidung mit der Oberfläche des Ohrs zustande kommt.FIGS. 10 and 11 show a further embodiment which was used in a patient with a much smaller cymba conchae. The otoplastic designated with 220 has a substantially smaller main body 256, which, however, is in turn spatially curved several times, so that the required undercut occurs with the surface of the ear.
Der Ansicht nach Fig. 11 kann entnommen werden, dass der sichtbare Teil der Otoplastik 220 minimal gehalten ist.11 that the visible part of the otoplastic 220 is kept to a minimum.
Selbstverständlich können für die erfindungsgemässen Otoplastiken alle gängigen Werkstoffe verwendet werden, wie z.B. hei ss- und kalt-polymerisierendes PMMA oder Lichtpolymerisat. Aufgrund des geringen Volumens der Otoplastik bieten sich insbesondere auch farbige Gestaltungen eventuell mit Schmuckapplikationen an. Aber auch Metalle, wie Edelstahl, Gold, Silber, Platin, Titan (Spritzguss- oder Schleuderguss-Verfahren) können eingesetzt werden, wobei es auch möglich ist mit der Galvanotechnik zu arbeiten. Of course, all common materials can be used for the earmolds according to the invention, e.g. hot and cold polymerizing PMMA or light polymer. Due to the small volume of the earmold, colored designs with jewelry applications may also be particularly suitable. Metals such as stainless steel, gold, silver, platinum, titanium (injection molding or centrifugal casting) can also be used, although it is also possible to work with electroplating.
