Abstract

A single opto-plastic 7 is provided which can be inserted into the auditory passage of an ear which is to be serviced and has an outside contour which matches the auditory passage and includes a hollow interior 6 which communicates with the outside through a sound passage 9. The hollow interior 6 is shaped so that it can receive an in the ear hearing aid 3 or a coupling (4, 5) for a behind the ear hearing aid, thus allowing either of the units to be quickly connected to the opto-plastic ear piece 7 so that comparative measurements can be made by the patient.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Durch­führung einer akustischen Vergleichsmessung gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1. Sie bezieht sich ebenfalls auf eine Otoplastik sowie eine Ankoppelvorrichtung für ein Hinter-dem-Ohr-Hörgerät, die bei einem solchen Verfahren vorzugsweise eingesetzt wer­den.The invention relates to a method for carrying out an acoustic comparison measurement according to the features of the preamble of claim 1. It also relates to an otoplastic and a coupling device for a behind-the-ear hearing device, which are preferably used in such a method.

Eine Otoplastik mit hohlem Innenraum, in die wenigstens teilweise ein In-dem-Ohr-Hörgerät einsetzbar ist, ist z.B. durch die CH-PS 648 172 vorbekannt.An otoplastic with a hollow interior, into which an in-the-ear hearing device can be at least partially inserted, is e.g. previously known from CH-PS 648 172.

Aus der europäischen Patentanmeldung 01 40 078 ist schließlich noch ein Hinter-dem-Ohr-Hörgerät vorbekannt, das mittels eines Schalleitungsschlauches mit einer Ohr­olive verbunden ist, die in den Hörgang des zu versorgen­den Ohres einsetzbar ist.Finally, a behind-the-ear hearing aid is also known from European patent application 01 40 078, which is connected by means of a sound cable tube to an ear olive that can be inserted into the ear canal of the ear to be supplied.

Die Frage, welches Gerät, also ein Hinter-dem-Ohr-Hör­gerät oder ein In-dem-Ohr-Hörgerät, für einen Hörge­schädigten in akustischer Hinsicht die beste Lösung ist, wird gewöhnlich durch akustische Vergleichsmessung ge­klärt. Dem Hörgeschädigten werden dazu in zeitlicher Auf­einanderfolge beide Gerätearten angesetzt und er trifft dann die Entscheidung, mit welcher Geräteart er besser hört.The question of which device, in other words a behind-the-ear hearing device or an in-the-ear hearing device, is the best solution for a hearing impaired person in terms of acoustics is usually clarified by means of acoustic comparative measurements. To this end, the hearing-impaired person is given both types of device in chronological succession and then makes the decision as to which type of device he can hear better.

Nachteilig ist, daß jede Geräteart eine eigene individuel­le Otoplastik (Gehäuseschale für In-dem-Ohr-Hörgeräte und Ohrolive für Hinter-dem-Ohr-Hörgeräte) zum Anschluß an den Gehörgang benötigt. Die Herstellung zweier ge­trennter Otoplastiken ist zeitaufwendig und teuer. Wer­den von jeder Geräteart mehrere Geräte akustisch mitein­ander verglichen, so vervielfachen sich entsprechend Zeitaufwand und Kosten. Bei Verwendung unterschiedlicher individueller Otoplastiken kann auch nicht immer sicher­gestellt werden, daß völlig gleiche akustische Ankopp­lungsverhältnisse existieren. Um einigermaßen gleiche Ankopplungsbedingungen zu gewährleisten, muß beim Ein­setzen der jeweiligen Otoplastik in den Gehörgang beson­ders sorgfältig vorgegangen werden (exakte Abdichtung nach außen etc.). Der Einsetzvorgang nimmt also ebenfalls unnötig viel Zeit in Anspruch. Da das akustische Gedächt­nis des Hörgeschädigten im allgemeinen relativ kurz ist, kann es zu Fehlinterpretationen des akustischen Verglei­ches kommen.It is disadvantageous that each type of device requires its own individual earmold (housing shell for in-the-ear hearing aids and ear olive for behind-the-ear hearing aids) for connection to the ear canal. Manufacturing two separate earmolds is time consuming and expensive. If several devices of each device type are acoustically compared with each other, time and costs are multiplied accordingly. When using different individual earmolds, it cannot always be ensured that completely identical acoustic coupling conditions exist. In order to ensure reasonably equal coupling conditions, special care must be taken when inserting the respective earmold into the ear canal (exact sealing to the outside, etc.). The insertion process also takes an unnecessarily long time. Since the acoustic memory of the hearing impaired is generally relatively short, the acoustic comparison can be misinterpreted.

Aufgabe vorliegender Erfindung ist es, Maßnahmen vorzu­sehen, die gegenüber bisher mit optimal geringem techni­schem Aufwand einen sehr viel sichereren akustischen Ver­gleich zwischen In-dem-Ohr- und Hinter-dem-Ohr-Hörgeräten erlauben.The object of the present invention is to provide measures which allow a much more reliable acoustic comparison between in-the-ear and behind-the-ear hearing aids compared to previously with minimal technical effort.

Die Aufgabe wird erfindungsgemäß mit einem Verfahren ge­mäß den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Sie wird ebenfalls mit einer Otoplastik gemäß den kennzeichnenden Merkmalen des Patentanspruchs 2 so­wie einer Ohrankoppelvorrichtung gemäß den kennzeichnen­den Merkmalen des Patentanspruchs 13 gelöst, die bei der Durchführung der erfindungsgemäßen akustischen Vergleichs­messung vorzugsweise eingesetzt werden.The object is achieved with a method according to the characterizing features of claim 1. It is also solved with an otoplastic according to the characterizing features of patent claim 2 and an ear coupling device according to the characterizing features of patent claim 13, which are preferably used when carrying out the acoustic comparative measurement according to the invention.

Die Erfindung macht es möglich, daß für den akustischen Vergleich lediglich eine einzelne Otoplastik bereitge­stellt zu werden braucht, die, gleichgültig, welche Ge­räteart gerade angeschlossen ist, im eingesetzten Zu­stand immer gleichartige akustische Verhältnisse schafft. Der Gesamtaufwand bei der Herstellung der Otoplastik ist optimal gering und kostensparend. Da die akustische An­kopplung nicht mehr problematisch ist, können die Geräte sehr viel rascher als bisher ausgetauscht werden. Die Gefahr von Fehlinterpretationen beim akustischen Ver­gleich ist jetzt praktisch ausgeschaltet. Hat sich der Hörgeschädigte für eine Geräteart entschieden, so kann die beim akustischen Vergleich eingesetzte Otoplastik für die Endversorgung weiterverwendet werden.The invention makes it possible that only a single earmold needs to be provided for the acoustic comparison, which, regardless of what type of device is currently connected, always creates similar acoustic conditions in the inserted state. The total effort in the production of the earmold is optimally low and cost-saving. Since the acoustic coupling is no longer a problem, the devices can be replaced much more quickly than before. The risk of misinterpretation in the acoustic comparison is now practically eliminated. If the hearing impaired person has decided on a type of device, the otoplastic used in the acoustic comparison can be used for the final care.

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausfüh­rungsbeispiels anhand der Zeichnung und in Verbindung mit den Unteransprüchen.Further advantages and details of the invention emerge from the following description of an exemplary embodiment with reference to the drawing and in conjunction with the subclaims.

Es zeigen:

  • Figur 1 die Herstellung einer Otoplastik gemäß der vor­liegenden Erfindung mittels eines Modulstempels,
  • Figur 2 in einer Explosionsdarstellung eine Otoplastik gemäß der Erfindung sowie ein In-dem-Ohr-Modulgerät bzw. ein entsprechend geformtes Anpaß-Adapterstück für die Ankopplung eines Hinter-dem-Ohr-Gerätes, die wahlweise in die Otoplastik einsetzbar sind,
  • Figur 3 einen Anschraubdeckel in Draufsicht,
  • Figur 4 ein Hinter-dem-Ohr-Hörgerät mit angekoppeltem Anpaß-Adapterstück,
  • Figuren 5 und 6 eine Modifikation des Ausführungsbei­spiels der Figur 2.
Show it:
  • 1 shows the production of an otoplastic according to the present invention by means of a module stamp,
  • 2 shows an exploded view of an otoplastic according to the invention and an in-the-ear modular device or a correspondingly shaped adapter piece for coupling a behind-the-ear device, which can be used optionally in the otoplastic,
  • FIG. 3 shows a screw-on cover in a top view,
  • FIG. 4 shows a behind-the-ear hearing device with a coupled adapter piece,
  • FIGS. 5 and 6 show a modification of the exemplary embodiment in FIG. 2.

Gemäß der Figur 1 wird mit Hilfe eines Modulstempels 1, der in der Außenkontur der Form des Gehäuses 2 eines In-­dem-Ohr-(IdO)Modulgerätes 3 bzw. eines Anpaß-Adapter­stückes 4 mit Schalleitungsschlauch 5 zum Anschluß an ein Hinter-dem-Ohr-(HdO)Gerät (s. Figuren 2 und 4) ent­spricht, ein hohler Innenraum 6 in einer normalen Otoplastik 7 geschaffen, deren Außenkontur 8 der Kontur des Gehörgangs des zu versorgenden Ohres angepaßt ist. Die Schallableitungsöffnung 9 der Otoplastik 7 ergibt sich dabei automatisch aufgrund des Endstutzens 10 am Modulstempel 1.According to FIG. 1, with the aid of a module stamp 1, which has the outer contour of the shape of the housing 2 of an in-the-ear (ITE) module device 3 or an adapter piece 4 with a switching cable hose 5 for connection to a rear Ear (BTE) device (see FIGS. 2 and 4) corresponds to a hollow interior 6 in a normal earmold 7, the outer contour 8 of which is adapted to the contour of the auditory canal of the ear to be supplied. The sound dissipation opening 9 of the earmold 7 arises automatically due to the end connector 10 on the module stamp 1.

Wie in der Figur 2 näher dargestellt ist, besitzen sowohl das Gehäuse 2 des IdO-Modulgerätes 3 als auch das Anpaß-­Adapterstück 4 entsprechende Endstutzen 11 bzw. 12, die jedoch im Gegensatz zum Endstutzen 10 des Modulstempels 1 je ein Außengewinde 13 bzw. 14 umfassen. Das jeweilige Außengewinde 13 bzw. 14 paßt zum Innengewinde 15 eines Anschraubdeckels 16. Der Anschraubdeckel 16 besitzt an seiner Stirnfläche 17 (s. Figur 3) siebartige Öffnungen 18. Er dient demnach gleichzeitig auch als Cerumen-Falle.As shown in more detail in FIG. 2, both the housing 2 of the ITE module device 3 and the adapter piece 4 have corresponding end connections 11 or 12, which, however, in contrast to the end connection 10 of the module stamp 1, each have an external thread 13 or 14 include. The respective external thread 13 or 14 matches the internal thread 15 of a screw-on cover 16. The screw-on cover 16 has sieve-like openings 18 on its end face 17 (see FIG. 3). Accordingly, it also serves as a cerumen trap.

Zur Durchführung eines akustischen Vergleiches wird bei­spielsweise zuerst das IdO-Modulgerät 3 in den hohlen Innenraum 6 der Otoplastik 8 eingeschoben, so weit, bis der Endstutzen 11 durch die Schallableitungsöffnung 9 ragt. Danach wird der Anschraubdeckel 16 auf das Außen­gewinde 13 des Endstutzens 11 geschraubt. Das IdO-Modul­gerät 3 sitzt jetzt fest und dicht im hohlen Innenraum 6 der Otoplastik 8. Es kann jetzt zusammen mit der Oto­plastik 8 zur Durchführung einer ersten akustischen Mes­ sung in den Gehörgang des zu versorgenden Ohres des Hörgeschädigten eingeführt werden.To carry out an acoustic comparison, for example, the ITE module device 3 is first inserted into the hollow interior 6 of the otoplastic 8 until the end connector 11 protrudes through the sound dissipation opening 9. Then the screw-on cover 16 is screwed onto the external thread 13 of the end connector 11. The ITE modular device 3 is now firmly and tightly seated in the hollow interior 6 of the otoplastic 8. It can now together with the otoplastic 8 to carry out a first acoustic measurement be inserted into the ear canal of the ear of the hearing impaired.

Nach Durchführung dieser ersten Messung wird die Kombi­nation aus IdO-Modulgerät 3 und Otoplastik 8 wieder aus dem Gehörgang entfernt. Durch Abschrauben des Anschraub­deckels 16 wird das IdO-Modulgerät 3 aus dem hohlen In­nenraum 6 der Otoplastik 8 wieder entfernt . Anstelle dieses Gerätes wird dann das Anpaß-Adapterstück 4 in den hohlen Innenraum 6 eingesetzt und wie zuvor beim Modul­gerät durch Aufschrauben des Anschraubdeckels 16 fixiert. Es kann jetzt eine zweite Messung mit Hilfe eines mit dem Anpaß-Adapterstück 4 über einen Schalleitungsschlauch 5 verbunden HdO-Gerätes (s. Figur 4) durchgeführt werden.After this first measurement has been carried out, the combination of ITE modular device 3 and otoplastic 8 is removed again from the auditory canal. By unscrewing the screw-on cover 16, the ITE modular device 3 is removed again from the hollow interior 6 of the otoplastic 8. Instead of this device, the adapter piece 4 is then inserted into the hollow interior 6 and, as previously in the case of the modular device, is fixed by screwing on the screw-on cover 16. A second measurement can now be carried out with the aid of a BTE device (see FIG. 4) connected to the adapter piece 4 via a formwork tube 5.

Damit kann also mit wenigen Handgriffen äußerst rasch von einer Messung mit der einen Geräteart auf eine Mes­sung mit der anderen Geräteart übergewechselt werden. Ein akustischer Vergleich ist in kürzester Zeitfolge möglich.It is therefore very quick to switch from a measurement with one type of device to a measurement with the other type of device in a few simple steps. An acoustic comparison is possible in the shortest possible time.

In der Figur 2 umfaßt das IdO-Modulgerät 3 an der Stirn­fläche 19 einen Einstellknopf 20 für einen Lautstärke­regler, ein weiteres Stellglied 21, einen Deckel 22 für das Batteriefach und eine Öffnung 23 für die Schallzu­führung.In FIG. 2, the ITE module device 3 comprises on the end face 19 an adjustment button 20 for a volume control, a further actuator 21, a cover 22 for the battery compartment and an opening 23 for the sound supply.

Das HdO-Gerät 24 in der Figur 4 besteht aus zwei Schalen 25 und 26. Am unteren Ende ist eine Batterielade 27 sichtbar und am oberen Ende ein Traghaken 28, mit wel­chem das Gerät 24 hinter dem Ohr getragen wird. Am vom Gerät abgewandten Ende 29 des Traghakens 28 ist der Schalleitungsschlauch 5 mit Anpaß-Adapterstück 4 ange­steckt. An der konvex nach außen gebogenen Rückseite des HdO-Gerätes 24 sind ein Einstellrädchen 30 für den Laut­ stärkeregler sowie ein Bedienungsschalter 31 angeordnet. Die Schalleintrittsöffnung ist mit 32 bezeichnet.The BTE device 24 in FIG. 4 consists of two shells 25 and 26. A battery charger 27 is visible at the lower end and a carrying hook 28 at the upper end, with which the device 24 is worn behind the ear. At the end 29 of the support hook 28 facing away from the device, the formwork cable hose 5 with the adapter piece 4 is connected. On the convex outward curved back of the BTE device 24 there are a dial 30 for the sound volume control and an operating switch 31 arranged. The sound inlet opening is designated 32.

Die Figuren 5 und 6 zeigen eine Alternativlösung, bei der ein Schalleitungsschlauch 5 direkt, d.h. ohne Zu­hilfenahme eines Anpaß-Adapterstückes, an der Otoplastik 7 angekoppelt wird.Figures 5 and 6 show an alternative solution, in which a formwork hose 5 directly, i.e. without the aid of an adapter piece to which otoplastic 7 is coupled.

Der Schalleitungsschlauch 5 besitzt dazu einen elasti­schen Abdichtpfropfen 33. Nach Durchschieben des Schall­leitungsschlauches 5 durch die Schallableitungsöffnung 9 in Richtung des Pfeiles 34 wird dieser Abdichtpfropfen 33 in die Schalleitungsöffnung gedrückt.For this purpose, the formwork tube 5 has an elastic sealing plug 33. After pushing the sound line tube 5 through the sound dissipation opening 9 in the direction of arrow 34, this sealing plug 33 is pressed into the formwork line opening.

Danach kann das dem Gerät zugewandte Ende des Schall­leitungsschlauches 5, wie in der Figur 4 dargestellt, auf das Ende 29 des Traghakens 28 des HdO-Gerätes 24 aufgesteckt werden.Then the end of the sound conduction tube 5 facing the device, as shown in FIG. 4, can be pushed onto the end 29 of the carrying hook 28 of the BTE device 24.

Im Falle der Figur 2 ist der Anpaß-Adapter vorzugsweise aus festem Kunststoff, z.B. einem Acetalcopolymerisat, gefertigt. Er kann aber selbstverständlich auch aus einem elastischen Material bestehen. Aufgrund der Ela­stizität kann der Anpaß-Adapter bereits so dicht im hohlen Innenraum sitzen, daß ein Anschraubmechanismus mit Anschraubkappe eventuell nicht mehr benötigt wird. Die Otoplastik ist vorzugsweise aus Acryl gefertigt.In the case of Figure 2, the adapter is preferably made of solid plastic, e.g. an acetal copolymer. Of course, it can also consist of an elastic material. Due to the elasticity, the adapter can already sit so tight in the hollow interior that a screw-on mechanism with screw-on cap may no longer be required. The earmold is preferably made of acrylic.
