Description

Die Erfindung betrifft einen Dome für ein in einen Ohrkanal einführbares Hörhilfegerät nach dem Oberbegriff des Anspruchs 1. Weiter betrifft die Erfindung ein Hörhilfegerät mit einem entsprechenden Dome.The invention relates to a dome for a hearing aid device that can be inserted into an ear canal, according to the preamble of claim 1. The invention also relates to a hearing aid device with a corresponding dome.

Als Hörhilfegerät wird allgemein eine tragbare Hörvorrichtung bezeichnet, die dazu dient, die Wahrnehmung des an das Ohr eines Nutzers anbrandenden Umgebungsschalls zu verbessern. Eine klassischerweise als "Hörgeräte" bezeichnete Unterklasse der Hörhilfegeräten ist zur Versorgung von Personen eingerichtet, die im medizinischen Sinne an einem Hörverlust leiden. Um deren zahlreichen individuellen Bedürfnissen entgegenzukommen, werden unterschiedliche Bauformen von Hörgeräten wie Hinter-dem-Ohr-Hörgeräte (HdO), Hörgeräte mit externem Hörer (RIC, Receiver in the Canal), In-dem-Ohr-Hörgeräte (IdO), oder auch Concha-Hörgeräte oder Kanal-Hörgeräte (ITE, CIC) angeboten. Die beispielhaft aufgeführten Hörgeräte werden am Außenohr oder im Gehörgang getragen. Darüber hinaus stehen auf dem Markt auch Knochenleitungshörhilfen, implantierbare oder vibrotaktile Hörhilfen zur Verfügung. Bei diesen erfolgt die Stimulation des geschädigten Gehörs entweder mechanisch oder elektrisch.A portable hearing device is generally referred to as a hearing aid device, which is used to improve the perception of the ambient sound burning onto the ear of a user. A subclass of hearing aids, classically referred to as "hearing aids", is set up for the care of people who suffer from a hearing loss in the medical sense. In order to meet their numerous individual needs, different types of hearing aids such as behind-the-ear hearing aids (BTE), hearing aids with an external receiver (RIC, Receiver in the Canal), in-the-ear hearing aids (ITE), or even Concha hearing aids or canal hearing aids (ITE, CIC) are offered. The hearing aids listed as examples are worn on the outer ear or in the auditory canal. In addition, bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. With these, the damaged hearing is stimulated either mechanically or electrically.

Um den im Ohr zu tragenden Teil des Hörhilfegeräts so innerhalb des Gehörgangs abzustützen, dass einerseits ein sicherer Halt und andererseits ein für ein dauerhaftes Tragen ausreichend hoher Tragekomfort gewährleistet ist, wird das Hör(hilfe)gerät üblicherweise mit einem Dome versehen, der einen flexibel an den Gehörgang anpassbaren Schirm aufweist.In order to support the part of the hearing aid device that is to be worn in the ear within the auditory canal so that on the one hand a secure hold and on the other hand a sufficiently high level of comfort for long-term wear is guaranteed, the hearing (aid) device is usually provided with a dome, which is flexible has the ear canal adjustable screen.

Gängige Domes werden aus Silikon gefertigt und sind, um den Durchtritt von Schall durch Dome sicherzustellen, mit zumindest einer Schalldurchtrittsöffnung versehen. Um eine Verschmutzung des Domes und damit des Hörgerätes mit Ohrwachs (Cerumen) zu verhindern kann die Schalldurchtritts-Öffnung mit einer schalldurchlässigen Membran versehen werden. Diese dem Cerumenschutz dienende Membran kann jedoch ebenfalls selbst mit Cerumen verunreinigt oder zugesetzt werden. Die dann notwendige Reinigung des Domes oder der Ersatz des Cerumenschutzes bzw. der Membran ist häufig aufwändig und insbesondere für den Endkunden alleine nicht umsetzbar. Auch der Einsatz eines Brückenelements in der Schalldurchtrittsöffnung, wie es beispielweise aus DE 10 2014 200 605 A1 bekannt ist, bietet keinen vollständigen Schutz gegen Verunreinigungen.Common domes are made of silicone and, in order to ensure the passage of sound through domes, have at least one sound passage opening Mistake. To prevent the dome and thus the hearing aid from being soiled with ear wax (cerumen), the sound passage opening can be provided with a sound-permeable membrane. However, this membrane used to protect cerumen can itself also be contaminated with cerumen or clogged. The then necessary cleaning of the dome or the replacement of the cerumen protection or the membrane is often complex and in particular cannot be implemented by the end customer alone. Also the use of a bridge element in the sound passage opening, as shown for example DE 10 2014 200 605 A1 is known does not provide complete protection against contamination.

Ein Dome nach dem Oberbegriff des Anspruchs 1 ist aus DE 10 2011 115 099 B3 bekannt. Dieser Dome weist ein Innenteil und einen Schirm mit einer Öffnung auf. Das Innenteil und der Schirm sind in zwei Teilen gefertigt. Das Innenteil ist hierbei aus einem formstabilen Kunststoff gebildet. Der Schirm ist dagegen aus einem weichen Kunststoff gebildet. Ein an den Schirm einstückig angeformtes Außenteil umgibt das Innenteil, wobei das Außenteil das Innenteil in axialer Richtung überragt. Innerhalb der Öffnung ist ein Cerumenschutz mit einem Schutzelement angeordnet. Das Schutzelement ist durch eine mit Löchern versehene Membran gebildet. Der Schirm und das einstückig damit hergestellten Außenteil lassen sich im Bereich der Öffnung zusammendrücken, wobei die das Schutzelement bildende Membran kalottenartig nach außen gedrückt wird. Hierdurch soll Cerumen, das sich gegebenenfalls in den Löchern der Membran gesammelt hat, hinreichend nach außen gedrückt werden, dass es abgekratzt oder abgewischt werden kann. Der Erfindung liegt daher die Aufgabe zugrunde, eine Möglichkeit anzugeben, den Schutz eines Hörhilfegeräts vor unerwünschten Verschmutzungen bei gleichzeitig vereinfachter Reinigung zu verbessern.A dome according to the preamble of claim 1 is off DE 10 2011 115 099 B3 known. This dome has an inner part and a screen with an opening. The inner part and the shade are made in two parts. The inner part is formed from a dimensionally stable plastic. The screen, however, is made of a soft plastic. An outer part formed integrally on the screen surrounds the inner part, the outer part protruding beyond the inner part in the axial direction. A cerumen protection with a protective element is arranged within the opening. The protective element is formed by a membrane provided with holes. The screen and the outer part produced in one piece with it can be pressed together in the region of the opening, the membrane forming the protective element being pressed outwards in the manner of a dome. This is intended to push cerumen that may have collected in the holes in the membrane to the outside sufficiently that it can be scraped off or wiped off. The invention is therefore based on the object of specifying a possibility of improving the protection of a hearing aid device against undesired soiling while at the same time simplifying cleaning.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen Dome mit den Merkmalen des Anspruchs 1 und ein Hörhilfegerät mit den Merkmalen des Anspruchs 12. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen und der nachfolgenden Beschreibung dargelegt.According to the invention, this object is achieved by a dome with the features of claim 1 and a hearing aid device with the features of claim 12. Advantageous embodiments of the invention are set out in the subclaims and the following description.

Der erfindungsgemäße Dome für ein in einen Ohrkanal einführbares Hörhilfegerät umfasst einen Innenteil und einen mit dem Innenteil einteilig gefertigten Schirm mit zumindest einer Öffnung. Innerhalb der Öffnung ist ein Cerumenschutz mit zumindest einem Schutzelement angeordnet, das in und entgegen der Einführrichtung des Domes in einen Ohrkanal flexibel umstülpbar ist. Erfindungsgemäß ist ein und entgegen der Einführrichtung des Domes bewegliches Reinigungselement stoffschlüssig mit dem Schirm verbunden.The dome according to the invention for a hearing aid device that can be inserted into an ear canal comprises an inner part and a screen which is manufactured in one piece with the inner part and has at least one opening. A cerumen protection with at least one protective element is arranged inside the opening, which can be flexibly turned inside out in and against the insertion direction of the dome into an ear canal. According to the invention, a cleaning element that is movable against the insertion direction of the dome is connected to the screen in a materially bonded manner.

Durch den Einsatz eines Domes mit einem entsprechend ausgebildeten Reinigungselement ist eine aufwandsarme Reinigung für den Träger des jeweiligen Hörhilfegeräts möglich. Zusätzliche Reinigungswerkzeuge oder der Austausch von Komponenten des Domes können entfallen. Hierbei erlaubt die flexibel umstülpbare Ausgestaltung des zumindest einen Schutzelements deren Bewegung sowohl in als auch entgegen der Einführrichtung des Domes in einen Ohrkanal. Das Reinigungselement lässt sich so vorteilhafterweise zur Reinigung in die hierfür vorgesehene Position und nach erfolgter Reinigung in die Ausgangsposition bewegen. Aufgrund der stoffschlüssigen Verbindung des Reinigungselementes mit dem Schirm des Domes ist die Positionierung der einzelnenn Komponenten des Domes zueinander festgelegt. Ein Verrutschen der einzelnen Komponenten ist nicht zu befürchten.The use of a dome with a correspondingly designed cleaning element enables low-cost cleaning for the wearer of the respective hearing aid device. Additional cleaning tools or the replacement of components of the dome can be omitted. Here, the flexibly evertable design of the at least one protective element allows its movement both in and against the direction of insertion of the dome into an ear canal. The cleaning element can thus advantageously be moved for cleaning into the position provided for this purpose and, after cleaning, into the starting position. Due to the material connection of the cleaning element with the screen of the dome, the positioning of the individual components of the dome is fixed to one another. Slipping of the individual components is not to be feared.

Vorzugsweise ist das Reinigungselement stoffschlüssig mit dem zumindest einen Schutzelement verbunden. Weiter bevorzugt ist der Cerumenschutz stoffschlüssig mit dem Schirm des Domes verbunden. Das Reinigungselement ist somit über das zumindest eine Schutzelement des Cerumenschutzes mit dem Schirm verbunden. Insgesamt ist im Rahmen der Erfindung der gesamte Dome mit dem Schirm, dem Innenteil, dem Cerumenschutz (inklusive des oder jeden Schutzelements) und dem Reinigungselement einteilig gefertigt. Der Dome ist zweckmäßigerweise aus einem flexiblen Material, wie beispielsweise aus einem thermoplastischen Elastomer oder aus Silikon gefertigt.The cleaning element is preferably cohesively connected to the at least one protective element. The cerumen protection is furthermore preferably materially connected to the screen of the dome. The cleaning element is thus connected to the screen via the at least one protective element of the cerumen protection. Overall, within the scope of the invention, the entire dome is manufactured in one piece with the screen, the inner part, the cerumen protection (including the or each protective element) and the cleaning element. The dome is expediently made from a flexible material such as a thermoplastic elastomer or silicone.

In einer weiter bevorzugten Ausgestaltung ist das zumindest eine Schutzelement in Einführrichtung des Domes gewölbt ausgebildet. Durch die gewölbte Ausbildung ist die Beweglichkeit des Schutzelementes in und entgegen der Einführrichtung des Domes sichergestellt und erlaubt so die Bewegung des stoffschlüssig mit dem Schutzelement verbundenen Reinigungselementes ebenfalls in und entgegen der Einführrichtung des Domes.In a further preferred embodiment, the at least one protective element is curved in the insertion direction of the dome. Due to the arched training the mobility of the protective element is ensured in and against the insertion direction of the dome and thus allows the movement of the cleaning element, which is firmly connected to the protective element, also in and against the insertion direction of the dome.

Um das Reinigungselement in und entgegen der Einführrichtung des Domes bewegen zu können, umfasst das Reinigungselement vorzugsweise ein Betätigungselement. Das Betätigungselement ist insbesondere stabförmig ausgebildet. Vorzugsweise erstreckt sich das Betätigungselement in Einführrichtung durch die zumindest eine im Schirm ausgebildete Öffnung hindurch. Auf diese Weise ist das Betätigungselement von der Außenseite des Schirmes für einen Hörgeräteträger zugänglich und ermöglicht diesem so die Nutzung des Reinigungselementes bzw. die Durchführung eines Reinigungsprozesses ohne zusätzliche Reinigungswerkzeuge.In order to be able to move the cleaning element in and against the insertion direction of the dome, the cleaning element preferably comprises an actuating element. The actuating element is designed in particular as a rod. The actuating element preferably extends in the insertion direction through the at least one opening formed in the screen. In this way, the actuating element is accessible from the outside of the screen for a hearing aid wearer and thus enables him to use the cleaning element or to carry out a cleaning process without additional cleaning tools.

Das zumindest eine Schutzelement ist vorzugsweise stoffschlüssig mit dem Betätigungselement des Reinigungselementes verbunden und somit über das Betätigungselement in und entgegen der Einführrichtung des Domes bewegbar. Das zumindest eine Schutzelement umfasst hierzu zweckmäßigerweise einen sich bezogen auf die Einführrichtung in radialer Richtung in die Öffnung des Schirms hinein erstreckenden Fuß, der stoffschlüssig mit dem Betätigungselement verbunden ist. Eine Bewegung des Betätigungselementes bewirkt so eine Bewegung des zumindest einen Schutzelementes.The at least one protective element is preferably materially connected to the actuating element of the cleaning element and can thus be moved via the actuating element in and against the insertion direction of the dome. For this purpose, the at least one protective element expediently comprises a foot which extends into the opening of the screen in the radial direction in relation to the insertion direction and which is connected to the actuating element in a materially bonded manner. A movement of the actuating element thus brings about a movement of the at least one protective element.

In bevorzugter Ausgestaltung weist das Reinigungselement bezogen auf die Einführrichtung zumindest einen sich in radialer Richtung nach außen erstreckenden Flügel auf. Dieser zumindest eine Flügel ist zweckmäßigerweise ebenfalls stoffschlüssig mit dem Betätigungselement des Reinigungselementes verbunden und erstreckt sich vorzugsweise ausgehend von dem Betätigungselement in die Öffnung des Schirmes hinein. Wird das Betätigungselement beispielsweise in Einführrichtung des Domes bewegt, so bewegt sich aufgrund der stoffschlüssigen Verbindung von Flügel und Betätigungselement auch das zumindest eine Schutzelement in dieser Richtung.In a preferred embodiment, the cleaning element has at least one wing that extends outward in the radial direction in relation to the insertion direction. This at least one wing is expediently also materially connected to the actuating element of the cleaning element and preferably extends from the actuating element into the opening of the screen. If the actuating element is moved, for example, in the insertion direction of the dome, the at least one protective element also moves in this direction due to the material connection between the wing and the actuating element.

Die Umfangsfläche des zumindest einen Flügels des Reinigungselements kommt hierbei - also bei Bewegung des Betätigungselements - vorteilhafterweise an der inneren Mantelfläche der Öffnung des Schirms zur Anlage. Weiter bevorzugt kommen die Seitenflächen des zumindest einen Flügels des Reinigungselements bei Bewegung des Betätigungselements an den Seitenflächen des Schutzelements zur Anlage. Auf diese Weise werden in der Öffnung des Schirms gesammelte Verunreinigungen bzw. Anlagerungen durch den Flügel des Reinigungselementes aus der Öffnung herausgeschoben und können entfernt werden.The circumferential surface of the at least one wing of the cleaning element here - that is, when the actuating element is moved - advantageously comes to rest on the inner surface of the opening of the screen. More preferably, the side surfaces of the at least one wing of the cleaning element come into contact with the side surfaces of the protective element when the actuating element is moved. In this way, impurities or deposits collected in the opening of the screen are pushed out of the opening by the wing of the cleaning element and can be removed.

Grundsätzlich sind die Anzahl der Schutzelemente des Cerumenschutzes und die Anzahl der Flügel des Reinigungselementes nicht begrenzt. In zweckmäßiger Ausgestaltung umfasst der Cerumenschutz so viele Schutzelemente wie das Reinigungselement Flügel umfasst. Insbesondere ist der Cerumenschutz mit mindestens zwei voneinander beabstandeten Schutzelementen ausgebildet und das Reinigungselement weist mindestens zwei Flügel auf, die bei einer Bewegung des Betätigungselements in die durch die Beabstandung der Schutzelemente voneinander ausgebildeten Zwischenräume eingreifen. Auch hierbei liegen die Umfangsflächen der Flügel innerhalb der Zwischenräume zweckmäßigerweise an der inneren Mantelfläche der Öffnung des Schirms an und die Seitenflächen der Flügel kommen bei Bewegung des Betätigungselements an den Seitenflächen des ihnen jeweils benachbarten Schutzelements zur Anlage.In principle, the number of protective elements of the cerumen protection and the number of wings of the cleaning element are not limited. In an expedient embodiment, the cerumen protection comprises as many protective elements as the cleaning element comprises wings. In particular, the cerumen protection is designed with at least two spaced apart protective elements and the cleaning element has at least two wings which, when the actuating element is moved, engage in the spaces formed by the spacing of the protective elements. Here, too, the peripheral surfaces of the wings within the spaces expediently rest on the inner surface of the opening of the screen and the side surfaces of the wings come into contact with the side surfaces of the protective element adjacent to them when the actuating element is moved.

Das erfindungsgemäße Hörhilfegerät umfasst einen Dome mit den Merkmalen der vorbeschriebenen Ansprüche. Durch den Einsatz eines solchen einteilig gefertigten Domes mit integriertem Reinigungswerkzeug entfallen zusätzlich Reinigungswerkzeuge. Auch auf eine Auswechslung des Domes bzw. des Cerumenschutzes kann verzichtet werden.The hearing aid device according to the invention comprises a dome with the features of the claims described above. The use of such a one-piece dome with an integrated cleaning tool eliminates the need for additional cleaning tools. There is also no need to replace the dome or the cerumen protection.

Unter einem Hörhilfegerät im Sinne der vorliegenden Erfindung werden unter anderem Headsets oder Kopfhörer und insbesondere klassische Hörgeräte verstanden. Das Hörhilfegerät selbst umfasst zweckmäßigerweise zumindest ein Mikrofon, eine Signalverarbeitungseinheit mit einem Verstärker und einen Receiver, sowie weitere elektronische und funktionale Komponenten. Der Dome des erfindungsgemäßen Hörhilfegerätes ist zweckmäßigerweise an oder auf dem im Ohrkanal getragenen Teil des jeweiligen Hörhilfegerätes positioniert.A hearing aid in the context of the present invention is understood to mean, inter alia, headsets or headphones and, in particular, classic hearing aids. The hearing aid itself expediently comprises at least one microphone, a signal processing unit with an amplifier and a receiver, as well as other electronic and functional components. The dome of the hearing aid device according to the invention is expediently positioned on or on the part of the respective hearing aid device worn in the ear canal.

Die für den erfindungsgemäßen Dome beschriebenen Vorteile und bevorzugten Ausführungsformen gelten gleichermaßen für das erfindungsgemäße Hörhilfegerät und können entsprechend sinngemäß auf dieses übertragen werden.The advantages and preferred embodiments described for the dome according to the invention apply equally to the hearing aid device according to the invention and can correspondingly be applied to this.

The dome 1 comprises an inner part 3 and a screen 5 made in one piece with the inner part 3. The screen 5 has an opening 7 within which a cerumen protection 9 is arranged. The screen 5 also has five openings 10 for open supply. The cerumen protection 9 is made in one piece with the screen 5 of the dome 1. The wax protection 9 comprises four protective elements 11 which can be flexibly turned inside out in and against the insertion direction 13 of the dome 1 into an ear canal. The protective elements 11 are arched in the insertion direction 13 of the dome 1 and are evenly spaced from one another over the circumference of the cerumen protection 9. Due to the spacing of the protective elements 11 from one another, spaces 15 are formed between these.

Weiter umfasst der Dome 1 ein in und entgegen der Einführrichtung 13 des Domes 1 bewegliches Reinigungselement 17. Das Reinigungselement 17 ist stoffschlüssig mit den Schutzelementen 11 des Cerumenschutzes 9 und somit auch mit dem Schirm 5 verbunden.Furthermore, the dome 1 comprises a cleaning element 17 which is movable in and against the insertion direction 13 of the dome 1. The cleaning element 17 is materially connected to the protective elements 11 of the cerumen protection 9 and thus also to the screen 5.

Das Reinigungselement 17 bzw. dessen stoffschlüssige Verbindung mit den Schutzelementen 11 ist in Fig. 2 zu sehen. Die stoffschlüssige Verbindung wird über ein Betätigungselement 19 des Reinigungselementes 17 realisiert. Das Betätigungselement 19 ist vorliegend stabförmig ausgebildet und erstreckt sich in Einführrichtung 13 durch die im Schirm 5 ausgebildete Öffnung 7 hindurch. Die Schutzelemente 11 umfassen jeweils einen sich bezogen auf die Einführrichtung 13 in radialer Richtung 21 in die Öffnung 7 des Schirms 5 hinein erstreckenden Fuß 23, der stoffschlüssig mit dem Betätigungselement 19 verbunden ist. Sowohl das Reinigungselement 17 selbst, als auch die vier Schutzelemente 11 des Cerumenschutzes 9 lassen sich über das Betätigungselement 19 in und entgegen der Einführrichtung 13 des Domes 1 bewegen.The cleaning element 17 or its integral connection with the protective elements 11 is shown in FIG Fig. 2 to see. The material connection is realized via an actuating element 19 of the cleaning element 17. In the present case, the actuating element 19 is rod-shaped and extends in the insertion direction 13 through the opening 7 formed in the screen 5. The protective elements 11 each comprise a foot 23 which extends into the opening 7 of the screen 5 in the radial direction 21 in relation to the insertion direction 13 and which is connected to the actuating element 19 in a materially bonded manner. Both the cleaning element 17 itself and the four protective elements 11 of the cerumen protection 9 can be moved in and against the insertion direction 13 of the dome 1 via the actuating element 19.

Weiter weist das Reinigungselement 17 bezogen auf die Einführrichtung 13 des Domes 1 vorliegend vier sich in radialer Richtung 25 nach außen erstreckende Flügel 27 auf. Drei der vier Flügel 27 sind in dem Ausschnitt des Domes 1 gemäß Fig. 2 zu erkennen. Die Flügel 27 des Reinigungselements 17 sind einteilig mit dem Betätigungselement 19 gefertigt und ebenfalls gleichmäßig voneinander beabstandet an diesem angeordnet.Furthermore, the cleaning element 17 has four wings 27 extending outward in the radial direction 25 in relation to the insertion direction 13 of the dome 1. Three of the four wings 27 are shown in the section of the dome 1 Fig. 2 to recognize. The wings 27 of the cleaning element 17 are manufactured in one piece with the actuating element 19 and are also arranged on the latter at a uniform distance from one another.

Bei einer Bewegung des Betätigungselements 19 in Einführrichtung 13 des Domes 1 greifen die Flügel 27 des Reinigungselementes 17 in die durch die Beabstandung der Schutzelemente 11 ausgebildeten Zwischenräume 17 ein. Hierbei liegen die Umfangsflächen 29 der Flügel 27 innerhalb der Zwischenräume 15 an der inneren Mantelfläche 31 der Öffnung 7 des Schirms 5 an. Dies ist aus den Darstellungen des Domes gemäß den Fig. 3 und 4 zu erkennen. Anhand der längsgeschnittenen Darstellung gemäß Fig. 3 wird weiter die stoffschlüssige Verbindung der Schutzelemente 11 mit dem Reinigungselement 17 deutlich. Die Füße 23 der Schutzelemente 11 sind jeweils stoffschlüssig mit dem Betätigungselement 19 des Reinigungselements 17 verbunden.When the actuating element 19 is moved in the insertion direction 13 of the dome 1, the wings 27 of the cleaning element 17 engage in the distance caused by the spacing of the protective elements 11 formed spaces 17. Here, the circumferential surfaces 29 of the wings 27 lie within the spaces 15 on the inner jacket surface 31 of the opening 7 of the screen 5. This is from the representations of the cathedral according to the Figures 3 and 4 to recognize. Based on the longitudinal section according to Fig. 3 the material connection of the protective elements 11 to the cleaning element 17 is also clear. The feet 23 of the protective elements 11 are each materially connected to the actuating element 19 of the cleaning element 17.

Der Querschnitt des Domes gemäß 4 zeigt zusätzlich, dass bei Eingriff der Flügel 27 des Reinigungselements 17 in die zwischen den Schutzelementen 11 ausgebildeten Zwischenräume 15 (bei Betätigung des Betätigungselementes) die Seitenflächen 33 der Flügel 27 an den Seitenflächen 35 der ihnen jeweils benachbarten Schutzelemente 11 zur Anlage kommt.The cross-section of the dome according to FIG. 4 also shows that when the wings 27 of the cleaning element 17 engage in the spaces 15 formed between the protective elements 11 (when the actuating element is actuated), the side surfaces 33 of the wings 27 on the side surfaces 35 of the protective elements 11 adjacent to them Plant is coming.

Die weiteren dreidimensionalen Darstellungen gemäß den Fig. 5 und 6 zeigen jeweils die vier Schutzelemente 11 des Cerumenschutzes 9 gemeinsam mit dem Reinigungselement 17. Anhand der Darstellungen ist die stoffschlüssige Verbindung der Füße 23 der jeweiligen Schutzelemente 11 mit dem Betätigungselement 19 des Reinigungselements 19 deutlich zu erkennen.The other three-dimensional representations according to Figures 5 and 6 each show the four protective elements 11 of the cerumen protection 9 together with the cleaning element 17. The representations clearly show the material connection of the feet 23 of the respective protective elements 11 with the actuating element 19 of the cleaning element 19.

Insgesamt ist der gesamte Dome 1 mit dem Schirm 5, dem Innenteil 3, dem Cerumenschutz 9 mit den vorliegend vier Schutzelementen 11 und dem Reinigungselement 17 einteilig aus einem thermoplastischen Elastomer gefertigt.Overall, the entire dome 1 with the screen 5, the inner part 3, the cerumen protection 9 with the present four protective elements 11 and the cleaning element 17 is made in one piece from a thermoplastic elastomer.
