Furthermore, the invention relates to a standard ear piece with a corresponding holding screen.

Weltweit ist eine Vielzahl von Menschen von Hörverlust und Schwerhörigkeit betroffen. Die Verringerung oder gar der Verlust der eigenen Hörleistung wirkt sich negativ auf die Kommunikation und den Kontakt zu anderen Menschen aus. Entsprechend tragen die meisten Menschen, die von Hörverlust betroffen sind, Hörhilfegeräte, die ihren Anwendern mit vermindertem Hörvermögen eine weitgehend normale akustische Wahrnehmung ermöglichen.Worldwide, a large number of people are affected by hearing loss and deafness. The reduction or even loss of one's own hearing performance has a negative effect on communication and contact with other people. Correspondingly, most people affected by hearing loss wear hearing aids that allow their users with impaired hearing to have a largely normal auditory perception.

Um den zahlreichen individuellen Bedürfnissen der Hörgeräteträger entgegenzukommen, werden unterschiedliche Bauformen von Hörgeräten angeboten. Bei BTE-Hörgeräten (Behind-the-Ear, auch Hinter-dem-Ohr bzw. HdO) wird ein Gehäuse mit Komponenten wie einer Batterie und der Signalverarbeitungseinheit hinter dem Ohr getragen. Ein flexibler, auch als Tube bezeichneter Schallschlauch leitet die akustischen Ausgabesignale des Receivers vom Gehäuse zum Gehörgang. RIC-Hörgeräte (Receiver-In-Canal) sind BTE-Hörgeräte mit einer elektrischen Verbindung zu einem im Ohr getragenen Lautsprecher. Bei den sogenannten ITE-Hörgeräten (In-the-Ear, auch IdO bzw. In-dem-Ohr) wird ein Gehäuse, welches sämtliche funktionale Komponenten einschließlich des Mikrofons und des Receivers enthält, zumindest teilweise im Gehörgang getragen. CIC-Hörgeräte (Completely-in-Canal) sind den ITE-Hörgeräten ähnlich, werden jedoch vollständig im Gehörgang getragen.To accommodate the numerous individual needs of the hearing aid wearers, different types of hearing aids are offered. BTE hearing aids (behind-the-ear, or behind-the-ear or BTE) wear a housing with components such as a battery and the signal processing unit behind the ear. A flexible sound tube, also referred to as a tube, directs the receiver's acoustic output signals from the housing to the ear canal. RIC (Receiver-In-Canal) hearing aids are BTE hearing aids with an electrical connection to a speaker worn in the ear. In the case of the so-called ITE hearing aids (in-the-ear, also IdO or in-the-ear), a housing which contains all the functional components, including the microphone and the receiver, is carried at least partially in the auditory canal. Completely-in-Canal (CIC) hearing aids are similar to ITE hearing aids, but are worn fully in the ear canal.

Die DE 202015000840 U1 offenbart eine Hörgeräte-Otoplastik für einen Ohrkanal zur Positionierung eines RIC-Hörsystems mit einem Otoplastikhohlkörper, eine in die Dämmplastik integrierte Lagertasche, an deren Ende eine Engstelle (Klemmung) zur Anbindung von Ex-Hörern unterschiedlicher RIC-Hörgeräte eingebracht ist und eine hinter der Engstelle befindliche Universal-Aufnahme für herstellerspezifische Klickhülsen. Die Hörgeräte-Otoplastik erlaubt eine herstellerunabhängige, also universelle Anbindungsmöglichkeit von RIC-Hörgerät.The DE 202015000840 U1 discloses a hearing aid earmold for an ear canal for positioning a RIC hearing system with an earmold hollow body, integrated into the insulating plastic storage pocket, at the end of a bottleneck (clamp) for connecting ex-earphones different RIC hearing aids is introduced and one behind the bottleneck Universal mount for manufacturer-specific click sleeves. The hearing aid ear mold allows a manufacturer-independent, so universal connection option of RIC hearing aid.

Aus der DE 10 2014 200 605 A1 ist ein Dome bekannt, der reversibel, d.h. lösbar, mit einem Receiver oder Hörschlauch eines Hörgerätes verbunden werden kann. Der Dome weist einen Cerumenschutz auf, der leicht und möglichst ohne den Dome vom Receiver oder Hörerschlauch zu lösen gereinigt werden kann. Der Cerumenschutz gemäß der DE 10 2014 200 605 A1 ist im Vergleich zum Innenteil weicher, wobei das Innenteil dazu ausgebildet, eine formschlüssige Verbindung mit einem korrespondierend geformten Adapter reversibel herzustellen. Der Cerumenschutz umfasst hierbei mindestens ein längliches Schutzelement, wobei eine Flächenprojektion jeden Schutzelements senkrecht auf die Grundfläche des Cerumenschutzes in Bezug auf den Flächenschwerpunkt der Grundfläche des Cerumenschutzes radial verläuft. Die Gestaltung des Cerumenschutzes aus flexiblen, länglichen Elementen, die als Speichen oder Lamellen ausgeführt sein können, gewährleistet eine gute Reinigbarkeit des Cerumenschutzes.; Die Konstruktion des Domes mit einem härteren Insert gewährleistet eine mechanisch stabile Verbindung, die dennoch zu Wartungs- oder Ersatzzwecken reversibel lösbar ist.From the DE 10 2014 200 605 A1 a dome is known, which can be reversibly, ie detachably, connected to a receiver or hearing tube of a hearing aid. The dome has a cerumen protection, which can be cleaned easily and without detaching the dome from the receiver or the receiver tube. The cerumen protection according to DE 10 2014 200 605 A1 is softer compared to the inner part, wherein the inner part is adapted to produce a positive connection with a correspondingly shaped adapter reversible. In this case, the cerumen protector comprises at least one elongated protective element, wherein a surface projection of each protective element extends radially perpendicular to the base surface of the cerumen protector with respect to the centroid of the surface of the cerumen protector. The design of the cerumen protection from flexible, elongated elements, which can be designed as spokes or lamellae, ensures a good cleanability of the cerumen protection. The construction of the dome with a harder insert ensures a mechanically stable connection, which is nevertheless reversibly detachable for maintenance or replacement purposes.

Die US 2015 049 897 A1 offenbart ein Ohrstück mit einem ein oberes Ende und ein unteres Ende aufweisenden Flansch, wobei der Flansch einen vom oberen Ende zum unteren Ende verlaufenden tränenförmig geschwungenen Querschnitt aufweist. Weiter umfasst der Flansch einen Innenkörper, durch den sich ein akustischer Kanal oder Schallkanal erstreckt. Der Flansch verschließt im eingesetzten Zustand des Ohrstückes zumindest teilweise einen Gehörgang für Umgebungsgeräusche und bildet zumindest eine teilweise Abdichtung gegen Luft in dem Gehörgang. Der Schallkanal erlaubt hierbei den Durchtritt von Schall in den Ohrkanal, wenn der Innenkörper mit einer Klangquelle verbunden ist.The US 2015 049 897 A1 discloses an earpiece having a flange having an upper end and a lower end, the flange having a tear-shaped curved cross-section extending from the upper end to the lower end. Furthermore, the flange comprises an inner body through which an acoustic channel or sound channel extends. The flange closes in the inserted state of the ear piece at least partially an ear canal for ambient noise and forms at least a partial seal against air in the ear canal. The sound channel here allows the passage of sound into the ear canal when the inner body is connected to a sound source.

Unabhängig von der Bauform kann auf standardisierte Hörsysteme, sogenannte Instant-fit Hörsysteme zurückgegriffen werden. Solche Instant-fit Hörsysteme sind für eine möglichst universelle Einsetzbarkeit gestaltet und beinhalten Standard-Ohrstücke, die klein genug dimensioniert sind, um unabhängig von der jeweiligen Anatomie im Ohrkanal des jeweiligen Hörgeräteträgers platziert werden zu können. Bei einem vergleichsweise großen Gehörgang des Hörgeräteträgers weisen solche Standard- Ohrstücke jedoch häufig keinen ausreichenden Halt im Gehörgang auf, da sie nicht an den individuellen Ohrkanal bzw. Gehörgang des Hörgeräteträgers angepasst sind. Die Ohrstücke verrutschen leicht.Irrespective of the design, standardized hearing systems, so-called instant-fit hearing systems, can be used. Such instant-fit hearing systems are designed to be as universally applicable as possible and include standard ear pieces which are small enough to be placed independently of the respective anatomy in the ear canal of the respective hearing aid wearer. In a comparatively large auditory canal of the hearing device wearer, however, such standard earpieces often do not have sufficient support in the auditory canal, since they are not adapted to the individual ear canal or auditory canal of the hearing device wearer. The ear pieces slip easily.

Ist das Standard-Ohrstück zu groß, wird häufig die akustische Wahrnehmung beeinträchtigt, da hier die für einen Druckausgleich im Ohr notwendige Belüftung nicht immer sichergestellt werden kann. Durch eine entsprechend geringe Belüftung werden unangenehme Rückkopplungseffekte begünstigt (Okklusionseffekt). Zusätzlich vermitteln Standard-Hörstücke dem Hörgeräteträger aufgrund des harten Gehäusematerials häufig ein unangenehmes Tragegefühl.If the standard ear piece is too large, the acoustic perception is often impaired, since the necessary for a pressure equalization in the ear ventilation can not always be ensured. By a correspondingly low ventilation unpleasant feedback effects are favored (occlusion effect). In addition, standard hearing aids often give the hearing aid user an uncomfortable feeling due to the hard housing material.

Trotz der verschiedenen Größen der erhältlichen Standard-Ohrstücke ist somit eine optimale Anpassung an die Anatomie des Gehörgangs eines jeweiligen Hörgeräteträgers derzeit nicht sichergestellt.Despite the different sizes of the available standard ear pieces thus optimal adaptation to the anatomy of the ear canal of a respective hearing aid wearer is currently not guaranteed.

Der Erfindung liegt als eine erste Aufgabe zugrunde, eine Möglichkeit anzugeben, die bei Verwendung eines Standard-Ohrstückes eine optimale Hörwahrnehmung und einen komfortablen Sitz des jeweiligen Hörgerätes erlaubt.The invention is a first object to provide a way that allows optimal hearing and a comfortable fit of the respective hearing aid when using a standard earpiece.

Als eine zweite Aufgabe liegt der Erfindung zugrunde, ein entsprechendes Standard-Ohrstück mit verbesserten Trageeigenschaften und verbessertem Hörkomfort bereitzustellen.A second object of the invention is to provide a corresponding standard ear piece with improved wearing properties and improved hearing comfort.

Die erste Aufgabe der Erfindung wird erfindungsgemäß gelöst durch einen Halte-Schirm für ein in einer Einführrichtung in einen Ohrkanal einführbares Standard-Ohrstück, umfassend ein endseitiges Kopfstück und einen daran anschließenden Flügelabschnitt, welcher derart ausgebildet ist, dass das Standard-Ohrstück darin mit wenigstens 50 % seiner Länge aufnehmbar ist, wobei der Flügelabschnitt von dem Standard-Ohrstück umlaufend beabstandet ist.The first object of the invention is achieved according to the invention by a holding screen for a standard ear piece which can be inserted into an ear canal in an insertion direction, comprising an end-side head piece and an adjoining wing portion, which is designed in such a way that the standard earpiece therein is at least 50 % of its length is receivable with the wing portion circumferentially spaced from the standard earpiece.

Die Erfindung basiert auf der Tatsache, dass standardisierte Ohrstücke, wie insbesondere CIC-Hörgeräte, RIC-Hörgeräte oder Ohrstücke eines BTE-Hörgerätes mit aufgesetzten elastischen Halte-Schirmen, sogenannten Domes, verwendet werden können. So kann zumeist ein ausreichender Halt im Gehörgang bzw. im Ohrkanal des jeweiligen Hörgeräteträgers erreicht werden. Die akustische Wahrnehmung wird hierdurch allerdings nicht verbessert. Gewünscht sind jedoch sowohl ein optimaler Tragekomfort als auch eine optimale Hörwahrnehmung.The invention is based on the fact that standardized ear pieces, such as in particular CIC hearing aids, RIC hearing aids or ear pieces of a BTE hearing aid with attached elastic holding screens, so-called Domes, can be used. Thus, a sufficient hold in the auditory canal or in the ear canal of the respective hearing device wearer can usually be achieved. However, this does not improve the acoustic perception. Desired, however, are both optimal wearing comfort and optimum hearing.

Die Erfindung begegnet diesen Anforderungen nun durch einen Halte-Schirm, welcher sich dem Ohrkanal anpasst und gleichzeitig eine ausreichende Belüftung sicherstellt. Der Halte-Schirm ist hierzu mit einem endseitigen Kopfstück und einen daran anschließenden Flügelabschnitt ausgebildet. Das Standard-Ohrstück ist in dem Halte-Schirm, insbesondere in dem Flügelabschnitt des Halteschirms mit wenigstens 50 % seiner Länge aufnehmbar und der Flügelabschnitt ist von dem Standard-Ohrstück umlaufend beabstandet.The invention now meets these requirements by a holding screen, which adapts to the ear canal and at the same time ensures adequate ventilation. The holding screen is for this purpose formed with an end-side head piece and an adjoining wing portion. The standard ear piece is receivable in the support screen, in particular in the wing portion of the support screen, at least 50% of its length, and the wing portion is circumferentially spaced from the standard earpiece.

Der Halte-Schirm ist hierbei insbesondere so lang ausgebildet, dass dieser im auf das Standard-Ohrstück aufgesteckten und im in den Ohrkanal eingesetzten Zustand die komplette Länge zwischen dem Isthmus, der Engstelle in der Ohrtrompete, und dem Eingang in den Ohrkanal abdeckt. Auf diese Weise wird der feste Halt des Ohrstückes innerhalb des Ohrkanals sichergestellt. Weiter wird durch die umlaufende Beabstandung zwischen dem Standard-Ohrstück und dem Halte-Schirm bzw. dessen Flügelabschnitt verhindert, dass das Standard- Ohrstück an der Wand des Ohrkanals anliegt oder an dieser anstößt und dem Hörgeräteträger so eine unangenehmes Gefühl vermittelt.In this case, the holding screen is designed in particular so long that it covers the entire length between the isthmus, the constriction in the ear trumpet and the input into the ear canal in the state inserted into the standard earpiece and inserted into the ear canal. In this way the firm hold of the ear piece is ensured within the ear canal. Furthermore, the circumferential spacing between the standard ear piece and the holding screen or its wing section prevents the standard ear piece from abutting against or abutting the wall of the ear canal and thus giving the hearing aid wearer an uncomfortable feeling.

Besonders bevorzugt umfasst der Halte-Schirm eine Anzahl von Belüftungsöffnungen, die das Kopfstück im Wesentlichen parallel zur Einführrichtung durchdringen und in den Innenraum des Flügelabschnitts münden. Der Innenraum ist im eingesetzten Zustand des Ohrstückes durch den Abstand zwischen der inneren Wandung des Halte-Schirms und der äußeren Wandung des Standard- Ohrstückes gegeben. Da der Innenraum des Flügelabschnitts an der nach außen gerichteten Seite des Halte-Schirms - also am Eingang des Ohrkanals - offen ausgebildet ist, stellt der Innenraum ein Belüftungsvolumen dar, das über die oder jede Öffnung die notwendige Belüftung und damit den Druckausgleich ermöglicht. Ein unerwünschter Okklusionseffekt bzw. Verschlusseffekt wird vermieden.Particularly preferably, the holding screen comprises a number of ventilation openings, which penetrate the head piece substantially parallel to the insertion direction and open into the interior of the wing section. The interior is given in the inserted state of the ear piece by the distance between the inner wall of the holding screen and the outer wall of the standard ear piece. Since the interior of the wing section on the outwardly facing side of the holding screen - ie at the entrance of the ear canal - is open, the interior represents a ventilation volume, which allows the necessary ventilation and thus the pressure equalization via the or each opening. An undesirable occlusion effect or closure effect is avoided.

Zweckmäßigerweise weitet sich der Querschnitt des Halte-Schirms in Einführrichtung auf. Das im eingesetzten Zustand des Halte-Schirms (gemeinsam mit dem Standard-Ohrstück) dem Isthmus zugewandte Kopfstück des Halte-Schirms weist somit einen kleineren Querschnitt auf, als der am Eingang des Ohrkanals befindliche Flügelabschnitt.Conveniently, the cross section of the holding screen widens in the insertion direction. The in the inserted state of the holding screen (together with the standard ear piece) the isthmus facing head of the holding screen thus has a smaller cross-section than the located at the entrance of the ear canal wing section.

Besonders bevorzugt verlaufen die Schwerpunkte der Querschnittsflächen des Halte-Schirms entlang der Einführrichtung auf einer gekrümmten Bahn. Der Halte-Schirm ist also in Einführrichtung mit einer Krümmung ausgebildet. Die Geometrie des Halte-Schirms, also sowohl die Aufweitung des Halte-Schirms als auch dessen Krümmung folgt somit der Kontur des Ohrkanals und erlaubt eine sichere und komfortable Positionierung des Ohrstückes. Gleichwohl lässt sich das Ohrstück damit sowohl für ein linkes Ohr als auch für ein rechtes Ohr einsetzen.Particularly preferably, the centers of gravity of the cross-sectional areas of the holding screen along the insertion direction on a curved path. The holding screen is thus formed in the insertion direction with a curvature. The geometry of the holding screen, so both the expansion of the holding screen and its curvature thus follows the contour of the ear canal and allows a secure and comfortable positioning of the ear piece. Nevertheless, the ear piece can thus be used for both a left ear and a right ear.

Der Halte-Schirm bzw. ein Standard-Ohrstück mit einem entsprechenden Halte-Schirm ist vorzugsweise reproduzierbar innerhalb des Ohrkanals positionierbar. Hierzu ist der Halte-Schirm bevorzugt aus zwei Teilen verschiedener Elastizität und damit auch unterschiedlicher Flexibilität ausgebildet. Vorzugsweise weist das Kopfstück eine geringere Elastizität auf als der Flügelabschnitt. Insbesondere weist das Material des Kopfstücks gegenüber dem Material des Flügelabschnitts eine geringere Elastizität auf. Der Halteschirm ist vorzugsweise aus einem Kunststoff gefertigt.The holding screen or a standard ear piece with a corresponding holding screen is preferably reproducibly positionable within the ear canal. For this purpose, the holding screen is preferably formed of two parts of different elasticity and thus also different flexibility. Preferably, the head piece has a lower elasticity than the wing portion. In particular, the material of the head piece has a lower elasticity than the material of the wing section. The retaining screen is preferably made of a plastic.

Um einen Halteschirm mit Abschnitten unterschiedlicher Elastizitäten zu fertigen, ist es besonders vorteilhaft, das Kopfstück und den Flügelabschnitt aus dem gleichen Material, aber mit voneinander verschiedenen Wandstärken herzustellen. Der Flügelabschnitt weist hierbei vorzugsweise eine geringere Wandstärke auf als das Kopfstück. Eine weiter bevorzugte Möglichkeit besteht darin, bei der Verwendung des gleichen Materials das Kopfstück und den Flügelabschnitt des Halteschirms mit unterschiedlichen Shore-Härten zu fertigen. Bei einem solchen Halteschirm hat der Flügelabschnitt zweckmäßigerweise eine geringere Shore-Härte, als das Kopfstück. Alternativ kann es von Vorteil sein, das Kopfstück und den Flügelabschnitt aus verschiedenen Materialien zu fertigen.In order to produce a holding screen with sections of different elasticities, it is particularly advantageous to produce the head piece and the wing section from the same material but with mutually different wall thicknesses. The wing section in this case preferably has a smaller wall thickness than the head piece. A further preferred possibility is to produce the head piece and the wing portion of the holding screen with different Shore hardness when using the same material. In such a retaining screen, the wing portion expediently has a lower Shore hardness than the head piece. Alternatively, it may be advantageous to manufacture the header and the wing section from different materials.

Das Kopfstück ist hierbei einerseits flexibel bzw. elastisch genug, um den gewünschten Komfort für den Hörgeräteträger sicherzustellen. Andererseits ist das Kopfstück ausreichend fest, um dem Hörgeräteträger beim Einsetzen des Ohrstückes in den Ohrkanal ein haptisches Feedback zu geben, ob er die vorgesehene Endposition - den Isthmus - erreicht hat. Ist dies der Fall, so ist ein Weiterschieben des Standard-Ohrstücks mit dem aufgesteckten Halte-Schirm ab diesem Punkt erschwert. Der Hörgeräteträger kann also davon ausgehen, dass das Ohrstück sich in der vorgesehen Position innerhalb des Ohrkanals befindet.The headpiece is on the one hand flexible or elastic enough to ensure the desired comfort for the hearing aid wearer. On the other hand, the head piece is sufficiently strong to give the hearing aid wearer a haptic feedback when inserting the earpiece into the ear canal, whether he has reached the intended end position - the isthmus. If this is the case, a further pushing of the standard ear piece with the attached holding screen from this point is difficult. The hearing aid wearer can therefore assume that the earpiece is located in the intended position within the ear canal.

Der flexible, elastischere Abschnitt des Halte-Schirms, also der Flügelabschnitt, gewährleistet entlang der Wandung des Ohrkanals den gewünschten Tragekomfort. Zweckmäßigerweise beträgt die Länge des Kopfstückes in Einführrichtung weniger als die Hälfte der Länge des Flügelabschnitts.The flexible, more elastic portion of the holding screen, so the wing section, along the wall of the ear canal ensures the desired comfort. Conveniently, the length of the head piece in the insertion direction is less than half the length of the wing portion.

Der Halte-Schirm ist zweckmäßigerweise über das Kopfstück an dem Standard-Ohrstück befestigbar bzw. im aufgesteckten Zustand an diesem befestigt. Hierzu umfasst das Kopfstück vorzugsweise eine Befestigungsöffnung zu einer kraftschlüssigen Verbindung mit dem Standard-Ohrstück. Die Befestigungsöffnung ist vorzugsweise an der einführseitigen Stirnfläche des Halte-Schirms ausgebildet. In die Befestigungsöffnung kann ein Befestigungselement des Standard-Ohrstückes eingeführt werden, um beide Komponenten lösbar aneinander zu fixieren.The holding screen is expediently fastened to the standard ear piece via the head piece or attached thereto in the plugged-on state. For this purpose, the head piece preferably comprises a fastening opening for a frictional connection with the standard ear piece. The attachment opening is preferably formed on the insertion-side end face of the holding screen. In the mounting hole, a fastener of the standard ear piece can be inserted to releasably fix both components together.

Die zweite Aufgabe der Erfindung wird erfindungsgemäß gelöst durch ein Standard-Ohrstück mit einem Halte-Schirm gemäß einer der vorbeschriebenen Ausgestaltungen. Bevorzugt ist die kraftschlüssige Verbindung als eine drehbare Clipverbindung ausgebildet.The second object of the invention is achieved by a standard ear piece with a holding screen according to one of the above-described embodiments. Preferably, the non-positive connection is designed as a rotatable clip connection.

Der Halte-Schirm ist auf das Standard-Ohrstück aufgesteckt. Hierzu greift vorzugsweise ein an der Stirnseite des Standard-Ohrstücks ausgebildetes Befestigungselement in die Befestigungsöffnung des Halte-Schirms ein. Das Befestigungselement ist in der Befestigungsöffnung bevorzugt drehbar aufgenommen. Aufgrund dieser drehbaren Ausgestaltung der Clipverbindung ist das Standard-Ohrstück gemeinsam mit dem Halte-Schirm sowohl für den Einsatz im Ohrkanal des rechten Ohres, als auch im Ohrkanal des linken Ohres geeignet.The holding screen is attached to the standard ear piece. For this purpose, preferably engages a formed on the end face of the standard earpiece fastener in the mounting opening of the holding screen. The fastening element is preferably rotatably received in the attachment opening. Due to this rotatable embodiment of the clip connection, the standard earpiece together with the holding screen is suitable both for use in the ear canal of the right ear and in the ear canal of the left ear.

Grundsätzlich kann als Standard-Ohrstück ganz allgemein jedes Ohrstück verwendet werden, welches sich im eingesetzten Zustand innerhalb des Gehörgangs des Hörgeräteträgers befindet. Besonders bevorzugt ist das Standard-Ohrstück als ein Standard-CIC-Hörgerät (Completely-In-Channel) ausgebildet. Das Gehäuse des Hörgerätes endet im äußeren Teil des Gehörganges und ist dadurch von außen kaum oder gar nicht sichtbar. Der Halte-Schirm ist dem Hörgerät wie vorbeschrieben aufgesetzt und erfüllt die Anforderungen an den Tragekomfort, den sicheren Sitz und die Belüftung des Ohres gleichermaßen.In principle, any earpiece which is located in the inserted state within the auditory canal of the hearing device wearer can generally be used as the standard earpiece. Particularly preferably, the standard ear piece is designed as a standard CIC hearing aid (Completely-In-Channel). The housing of the hearing aid ends in the outer part of the ear canal and is characterized by little or no visible from the outside. The holding screen is attached to the hearing aid as described above and meets the requirements for comfort, secure fit and ventilation of the ear alike.

Die zu den bevorzugten Ausgestaltungen des Halte-Schirms genannten Vorteile können sinngemäß auf entsprechende Ausgestaltungen des Standard-Ohrstückes übertragen werden.The advantages referred to the preferred embodiments of the holding screen can be analogously transferred to corresponding embodiments of the standard ear piece.

Im Folgenden werden Ausführungsbeispiele der Erfindung anhand einer Zeichnung näher erläutert. Dabei zeigen:

Fig. 1 zeigt einen Halte-Schirm 1, der einem als Instant-Fit-CIC-Hörgerät (schematisch dargestellt) ausgebildetem Standard-Ohrstück 3 aufgesetzt ist. Das Instant-Fit-CIC-Hörgerät 3 mit dem Halte-Schirm 1 ist innerhalb eines Ohrkanals 5 eingesetzt. Zum Einsetzen des Instant-Fit-CIC-Hörgerätes 3 mit aufgesetztem Halte-Schirm 1 werden beide Komponenten gemeinsam in Einführrichtung 7 in den Ohrkanal 5 eingeschoben. Der Halte-Schirm 1 deckt hierbei die komplette Länge zwischen dem Isthmus 9, also der Engstelle in der Ohrtrompete 11, und dem Eingang 13 in den Ohrkanal 5 ab. Fig. 1 shows a holding screen 1, which is a set as an instant-fit CIC hearing aid (shown schematically) standard earpiece 3 is placed. The instant fit CIC hearing aid 3 with the holding screen 1 is inserted within an ear canal 5. To insert the instant-fit CIC hearing aid 3 with attached holding screen 1, both components are inserted together in the insertion direction 7 in the ear canal 5. In this case, the holding screen 1 covers the entire length between the isthmus 9, that is to say the constriction in the ear trumpet 11, and the input 13 into the ear canal 5.

Der Halte-Schirm 1 umfasst ein endseitiges Kopfstück 15 und einen sich an das Kopfstück 15 anschließenden Flügelabschnitt 17, wobei die Länge des Kopfstückes 15 in Einführrichtung 7 weniger als die Hälfte der Länge des Flügelabschnitts 17 beträgt.The holding screen 1 comprises an end-side head piece 15 and a wing portion 17 adjoining the head piece 15, wherein the length of the head piece 15 in the insertion direction 7 is less than half the length of the wing portion 17.

Das Kopfstück 15 weist eine geringere Elastizität auf als der Flügelabschnitt 17. Wird das Instant-Fit-CIC-Hörgerät 3 in den Ohrkanal 5 eingeführt, so ist bei Erreichen der Endposition, also bei Erreichen des Isthmus 9 ein weiteres Einschieben des Instant-Fit-CIC- Hörgeräts 3 erschwert. Der Hörgeräteträger weiß dann, dass das Instant-Fit-CIC- Hörgerät 3 weit genug im Ohrkanal 5 positioniert ist.The head piece 15 has a lower elasticity than the wing portion 17. If the instant-fit CIC hearing aid 3 is inserted into the ear canal 5, upon reaching the end position, ie when the isthmus 9 is reached, further insertion of the instant fit is possible. CIC hearing aid 3 difficult. The hearing aid wearer then knows that the instant fit CIC hearing aid 3 is positioned far enough in the ear canal 5.

Durch den flexiblen Flügelabschnitt 17 wird sichergestellt, dass sich der Halte-Schirm 1 der Anatomie des Ohrkanals 5 anpasst, so dass der gewünschte Tragekomfort für den Hörgeräteträger erreicht wird.By the flexible wing portion 17 ensures that the holding screen 1 of the anatomy of the ear canal 5 adapts, so that the desired comfort for the hearing aid wearer is achieved.

Der Halte-Schirm 1 ist über eine kraftschlüssige drehbare Clipverbindung 19 an dem Instant-Fit-CIC-Hörgerät 3 befestigt. Hierzu ist an der einführseitigen Stirnfläche 20 des Kopfstücks 15 eine Befestigungsöffnung 21 ausgebildet, in die ein Befestigungselement 23, wie beispielsweise ein Kugelkopf, des Standard-Ohrstücks 3 eingreift.The holding screen 1 is attached to the instant-fit CIC hearing aid 3 via a non-positive rotatable clip connection 19. For this purpose, a fastening opening 21 is formed on the insertion-side end face 20 of the head piece 15, into which a fastening element 23, such as a ball head, of the standard ear piece 3 engages.

Das Standard-Ohrstück 3, also das Instant-Fit-CIC-Hörgerät, ist innerhalb des Halte-Schirms 1 mit vorliegend 75 % seiner Länge L aufgenommen. Der Flügelabschnitt 17 ist hierbei von dem Standard-Ohrstück 3 umlaufend beabstandet. Durch die umlaufende Beabstandung zwischen dem Instant-Fit-CIC-Hörgerät 3 und dem Halte-Schirm 1 bzw. dessen Flügelabschnitt 17 wird verhindert, dass das Instant-Fit-CIC-Hörgerät 3 an der Wandung des Ohrkanals 5 anliegt und so einen für den Hörgeräteträger unangenehmen Druck ausübt.The standard earpiece 3, so the instant-fit CIC hearing aid is included within the holding screen 1 with presently 75% of its length L. The wing portion 17 is in this case circumferentially spaced from the standard earpiece 3. The circumferential spacing between the instant-fit CIC hearing aid 3 and the holding screen 1 or its wing section 17 prevents the instant-fit CIC hearing device 3 from abutting against the wall of the ear canal 5 and thus preventing the wearer from suffering Hearing aid wearer exerts unpleasant pressure.

Um die für eine optimale Hörwahrnehmung notwendige Belüftung des Ohres bzw. den Druckausgleich sicherzustellen, umfasst der Halte-Schirm 1 mehrere Belüftungsöffnungen 25, die das Kopfstück 15 im Wesentlichen parallel zur Einführrichtung 7 durchdringen und in den Innenraum 27 des Flügelabschnitts 17 münden. Der Innenraum 27 ist hierbei durch einen Ringraum mit dem Abstand A zwischen der inneren Wandung des Halte-Schirms 1 und der äußeren Wandung des Instant-Fit-CIC-Hörgeräts 3 definiert.In order to ensure the ventilation of the ear or pressure equalization necessary for optimum hearing, the holding screen 1 comprises a plurality of ventilation openings 25, which penetrate the head piece 15 substantially parallel to the insertion direction 7 and open into the interior 27 of the wing section 17. The interior 27 is defined here by an annular space with the distance A between the inner wall of the holding screen 1 and the outer wall of the instant-fit CIC hearing device 3.

Die Belüftungsöffnungen 25 sind wie auch die Befestigungsöffnung 21 an der einführseitigen Stirnfläche 20 des Kopfstücks 15 ausgebildet. In Kombination mit dem durch die umlaufende Beabstandung zwischen dem Standard-Ohrstück 3 und dem Flügelabschnitt 17 des Halte-Schirms 1 resultierenden Innenraum 27 kann eine Belüftung des Ohres durch den Innenraum 27 des Halte-Schirms 1 hindurch erfolgen. Belüftungsöffnungen in dem Instant-Fit-CIC-Hörgerät 3 sind nicht notwendig.The ventilation openings 25 are formed as well as the attachment opening 21 on the insertion-side end face 20 of the head piece 15. In combination with the space 27 resulting from the circumferential spacing between the standard ear piece 3 and the wing section 17 of the holding screen 1, ventilation of the ear can take place through the interior space 27 of the holding screen 1. Vents in the instant fit CIC hearing aid 3 are not necessary.

Der Querschnitt 29 des Halte-Schirms 1 weitet sich entgegen der Einführrichtung 7 auf, die Querschnittsflächen 30 werden also entgegen der Einführrichtung 7 größer. Hierbei verlaufen die Schwerpunkte 31 der Querschnittsflächen des Halte-Schirms 1 entlang der Einführrichtung 7 auf einer gekrümmten Bahn 33. Dies wird besonders aus der Darstellung des Halte-Schirms 1 gemäß Fig. 2 ersichtlich. Man erkennt hier die Krümmung des Halte-Schirms 1, die exemplarisch für einige nicht gekennzeichnete Querschnittsflächen eingezeichnet sind. Die Schwerpunkte 31 der Querschnittsflächen liegen nicht auf einer Geraden. Durch die Krümmung ist die Form des Halte-Schirms 1 sowohl der Form des Ohrkanals, als auch der Form des Instant-Fit-CIC-Hörgerätes 3 angepasst. Die Krümmung spiegelt die Anatomie des Ohrkanals 5 wieder.The cross-section 29 of the holding screen 1 expands counter to the insertion direction 7, the cross-sectional areas 30 are thus opposite the direction of insertion 7 larger. Here, the focal points 31 of the cross-sectional areas of the holding screen 1 along the insertion direction 7 on a curved path 33. This is particularly apparent from the representation of the holding screen 1 according to Fig. 2 seen. It can be seen here the curvature of the holding screen 1, which are shown by way of example for some unmarked cross-sectional areas. The centroids 31 of the cross-sectional areas are not on a straight line. Due to the curvature, the shape of the holding screen 1 is adapted both to the shape of the ear canal and to the shape of the instant fit CIC hearing aid 3. The curvature reflects the anatomy of the ear canal 5 again.

Das Instant-Fit-CIC-Hörgerät 3 in alleiniger Darstellung ist Fig. 3 zu entnehmen. Anhand der Darstellung ist auch dessen gekrümmte Form zu sehen. Weiter ist das stirnseitige Befestigungselement 23 zu erkennen, welches der Befestigung des Halte-Schirms 1 dient. Das Befestigungselement 23 greift beim Aufstecken des Halte-Schirms 1 in die an der einführseitigen Stirnfläche 20 des Kopfstücks 15 ausgebildete Befestigungsöffnung 21 ein. Auf diese Weise kommt die kraftschlüssige und drehbare Clipverbindung 19 zwischen dem Instant-Fit-CIC-Hörgerät 3 und dem Halte-Schirm 1 zustande.The Instant Fit CIC Hearing Aid 3 is in sole representation Fig. 3 refer to. The illustration also shows its curved shape. Next, the front-side fastener 23 can be seen, which serves to attach the holding screen 1. When fastening the holding screen 1, the fastening element 23 engages in the fastening opening 21 formed on the insertion-side end face 20 of the head piece 15. In this way, the non-positive and rotatable clip connection 19 between the instant-fit CIC hearing aid 3 and the holding screen 1 comes about.

Die Befestigungsöffnung 21 des Halte-Schirms 1 ist in den Fig. 4 und 5 noch einmal deutlich zu sehen. In Fig. 4 ist eine der Belüftungsöffnungen 25, die das Kopfstück 15 im Wesentlichen parallel zur Einführrichtung 7 durchdringen und in den Innenraum 27 des Flügelabschnitts 17 münden, zu erkennen. Auch ist anhand der Darstellung gemäß Fig. 4 zu erkennen, dass die Länge des weniger elastischen und entsprechend weniger flexiblen Kopfstückes 15 in Einführrichtung 7 weniger als die Hälfte der Länge des Flügelabschnitts 17 beträgt.The attachment opening 21 of the holding screen 1 is in the Fig. 4 and 5 to see clearly again. In Fig. 4 is one of the ventilation openings 25, which penetrate the head piece 15 substantially parallel to the insertion direction 7 and open into the interior 27 of the wing portion 17 can be seen. Also, based on the illustration according to Fig. 4 to recognize that the length of the less elastic and correspondingly less flexible head piece 15 in the insertion direction 7 is less than half the length of the wing portion 17.

Fig. 5 zeigt in einer Schnittdarstellung einen Teilabschnitt 35 des Halte-Schirms 1. Dieser Darstellung sind die Belüftungsöffnungen 25 ebenso wie die Befestigungsöffnung 21 an der einführseitigen Stirnfläche 20 des Kopfstücks 15 zu entnehmen. Fig. 5 shows a sectional view of a portion 35 of the holding screen 1. This illustration, the ventilation openings 25 as well as the attachment opening 21 on the insertion-side end face 20 of the head piece 15 can be seen.

Weiter ist der Übergang zwischen dem den Halte-Schirm 1 bildenden Kopfstück 15 und dem sich diesem anschließenden Flügelanschnitt 17 zu erkennen.Next, the transition between the holding screen 1 forming the head piece 15 and this subsequent wing gate 17 can be seen.
