Abstract

A cerumen trap for hearing aids comprises a sound channel and a plurality of perforations arranged in a stellate pattern around the sound channel which connect the sound outlet of an earpiece with the sound channel. A cylindrical component (1) with a connecting piece (3) which surrounds the sound channel can be inserted in the hearing aid. A number of angle pieces (4) with locking noses (5) are arranged on the periphery of the component (1). The sound outlet opening (2) can be closed off from the exterior by a cap (7) which has a locking groove (8) on the inner wall and which engages with the locking noses (5).

Description

Die Erfindung betrifft einen Cerumenfänger für Schwerhörigengeräte gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a cerumen trap for hearing impaired devices according to the preamble of claim 1.

Derartige Cerumenfänger sind bereits bekannt. So zeigt z.B. die DE - B 1 259 951 ein Hörgerät mit einer Schutzvorrichtung gegen das Eindringen von Cerumen in das Innere des Hörgerätes. Zu diesem Zweck ist ein U-förmiges Bauteil in den Schallausgangskanal des Hörgerätes eingesetzt, welches zwei seitliche Schalldurchlässe aufweist. Das Bauteil besitzt einen Sockel, in den der Zapfen eines den Schallausgang nach außen abdeckenden Deckels einrastend eingesetzt ist. Der Deckel weist an seiner Innenfläche vier gegeneinander versetzte Stege auf, die in Verbindung mit den Durchlässen den Schallausgang des Gerätes bilden. Bei dieser Anordnung kann immer noch Cerumen seitlich in die Schallausgänge eindringen. Bei zu großem Cerumendruck wird der Deckel so weit an den elastischen Körper des Hörgerätes angedrückt, daß der Schallausgang verschlossen wird.Such cerumen traps are already known. For example, DE - B 1 259 951 a hearing device with a protective device against the penetration of cerumen into the interior of the hearing device. For this purpose, a U-shaped component is inserted into the sound output channel of the hearing aid, which has two lateral sound passages. The component has a base into which the pin of a cover that covers the sound output to the outside is inserted in a snap-in manner. On its inner surface, the cover has four webs offset from one another, which, in conjunction with the passages, form the sound output of the device. With this arrangement, cerumen can still penetrate laterally into the sound outputs. If the wax pressure is too high, the lid is pressed so far against the elastic body of the hearing aid that the sound outlet is closed.

Aufgabe der Erfindung ist es, einen Cerumenfänger der eingangs genannten Art zu schaffen, bei dem das Eindringen von Cerumen mit großer Sicherheit verhindert wird, wobei auch ein Verschließen des Schallausgangs bei hohem Cerumendruck vermieden wird, während die immer noch erforderliche Reinigung des Cerumenfängers erleichtert wird.The object of the invention is to provide a cerumen catcher of the type mentioned at the outset, in which the penetration of cerumen is prevented with great certainty, and also closing the sound outlet at high cerumen pressure is avoided, while the still necessary cleaning of the cerumen trap is facilitated.

Diese der Erfindung zugrunde liegende Aufgabe wird gemäß den Merkmalen des Patentanspruches 1 gelöst.This object of the invention is achieved according to the features of claim 1.

Weitere Merkmale der Erfindung sind den weiteren Ansprüchen zu entnehmen.Further features of the invention can be found in the further claims.

Die Erfindung wird nunmehr anhand eines Ausführungsbeispieles in Verbindung mit den beigefügten Figuren näher erläutert.The invention will now be explained in more detail using an exemplary embodiment in conjunction with the accompanying figures.

In den Figuren zeigt:

eine Draufsicht auf Fig. 1;
Fig. 3
eine Schnittansicht der Fig. 1;

The figures show:
Fig. 1
schematically shows a greatly enlarged side view of the cylindrical component for a cerumen trap;
Fig. 2
a plan view of Fig. 1;
Fig. 3
a sectional view of Fig. 1;
Fig. 4
a cap seen from above;
Fig. 5
a sectional view of the cap shown in Fig. 4 and
6A and 6B
the entire cerumen trap in two different views.

Der in den Figuren gezeigte Cerumenfänger ist sehr stark vergrößert dargestellt. In Wirklichkeit weist er einen Durchmesser über alles von knapp 4 mm auf.The cerumen trap shown in the figures is shown on a very large scale. In reality, it has a diameter of almost 4 mm.

Fig. 1 zeigt dabei das in ein Hörgerät oder in eine Otoplastik einsetzbare zylinderförmige Bauteil 1 mit einem durchgehenden Schallkanal 2, welcher an seinem einen Ende einen etwa 1,2 mm langen Anschlußstutzen 3 trägt. Selbstverständlich sind diese Maßangaben in keiner Weise als beschränkend aufzufassen.1 shows the cylindrical component 1 that can be inserted into a hearing aid or into an otoplastic and has a continuous sound channel 2, which carries an approximately 1.2 mm long connecting piece 3 at one end. Of course, these dimensions are in no way to be interpreted as restrictive.

Wie aus Fig. 1 in Verbindung mit Fig. 2 deutlich zu sehen, weist das Bauteil 1 im Anschluß an den Anschlußstutzen an seinem Umfang mehrere, z.B. vier Winkelstücke 4 auf. Es können selbstverständlich auch nur 3 oder mehr als 4 sein. Diese Winkelstücke sind gleichmäßig am Umfang des Bauteils 1 angeordnet.As can be clearly seen from Fig. 1 in connection with Fig. 2, the component 1 has several, e.g. four elbows 4. Of course, there can only be 3 or more than 4. These angle pieces are arranged uniformly on the circumference of the component 1.

An ihrem oberen Ende tragen die Winkelstücke Rastnasen 5, während am unteren Ende ein waagerecht verlaufender Sockelabschnitt 6 vorgesehen ist, dessen Bedeutung noch erläutert wird.At their upper end, the elbows have latching noses 5, while a horizontally extending base section 6 is provided at the lower end, the meaning of which is explained below.

Eine Schnittansicht durch dieses Bauteil 1 zeigt Fig. 3
Auf dieses Bauteil ist die in Fig. 4 und 5 gezeigte Kappe 7 aufsetzbar. Zu diesem Zweck weist die Kappe 7 an ihrer innenliegenden vertikalen Oberfläche eine vorzugsweise, aber nicht notwendigerweise rundumlaufende Rastnut auf.3 shows a sectional view through this component 1
The cap 7 shown in FIGS. 4 and 5 can be placed on this component. For this purpose, the cap 7 has on its inner vertical surface a preferably, but not necessarily, all-round locking groove.

In den Figuren 6A und 6B ist der neue Cerumenfänger in einer teilweise im Schnitt dargestellten Seitenansicht und in einer Ansicht von oben dargestellt. Man erkennt nunmehr deutlich, daß zwischen der Oberkante des Bauteils 1 und der Unterseite der Kappe 7 ein Hohlraum 9 gebildet ist. Durch die in beiden Figuren eingezeichneten Pfeile ist der Verlauf des Schallaustritts deutlich dargestellt.FIGS. 6A and 6B show the new cerumen trap in a side view, partly in section, and in a view from above. It can now be clearly seen that a cavity 9 is formed between the upper edge of the component 1 and the underside of the cap 7. The course of the sound outlet is clearly shown by the arrows drawn in both figures.

Wenn man die Abstände zwischen den einzelnen Winkelstücken 4 und die Größe des Hohlraums 9 entsprechend wählt, läßt sich so ein gewünschtes Resonanzverhalten im Ausgang des Hörgerätes erzielen.If one chooses the distances between the individual angle pieces 4 and the size of the cavity 9 accordingly, a desired resonance behavior can be achieved in the output of the hearing aid.

Man sieht ferner, daß durch die Wahl der Abmessungen der Winkelstücke und der Rastnasen bzw. des Ortes der Rastnut 8 in der Kappe 7 die Größe des Hohlraums 9 in geringem Maße variiert werden kann.One can also see that by choosing the dimensions of the elbows and the locking lugs or the location of the locking groove 8 in the cap 7, the size of the cavity 9 can be varied to a small extent.

Man erkennt ferner, daß bei dieser neuen Anordnung durch die die Sockelteile 6 der Winkelstücke übergreifenden Seitenwände der Kappe 7 das Eindringen von Cerumen mit Sicherheit verhindert wird.It can also be seen that with this new arrangement, the penetration of cerumen is prevented with certainty by the side walls of the cap 7 which overlap the base parts 6 of the angle pieces.

Dieser Cerumenfänger ist sehr leicht zu reinigen, da die Kappe gut abnehmbar ist. Trotzdem sitzt die Kappe normalerweise ausreichend fest auf dem zylinderförmigen Bauteil, da durch die in die Rastnut 8 der Kappe 7 eingerastete Rastnase 4 in Verbindung mit der Auflage des Kappenrandes auf dem Sockelteil 6 der Winkelstücke 4 eine Klemmwirkung erzielt wird.This cerumen catcher is very easy to clean because the cap is easily removable. Nevertheless, the cap normally sits sufficiently firmly on the cylindrical component, since a locking effect is achieved by the locking lug 4 which is latched into the locking groove 8 of the cap 7 in conjunction with the support of the cap edge on the base part 6 of the angle pieces 4.

Die Erfindung läßt sich auch durch eine mechanische Umkehrung verwirklichen. Das Bauteil 1 wäre dann an seiner auf den Gehörgang gerichteten Oberfläche glatt und hätte an seiner Außenfläche eine Rastnut. Die Kappe 7 würde dann an der Innenwand eine Anzahl von Rastnasen in Verbindung mit einer gleichen Anzahl von Abstandsstücken aufweisen. Diese würden dann ebenfalls nicht nur verhindern, daß die Kappe zu tief eingestzt wird, sondern auch eine Klemmwirkung ausüben.The invention can also be implemented by mechanical reversal. The component 1 would then be smooth on its surface facing the auditory canal and would have a locking groove on its outer surface. The cap 7 would then have a number of latching lugs in connection with an equal number of spacers on the inner wall. These would then not only prevent the cap from being inserted too deeply, but would also have a clamping effect.
