Description

Cerumenfänger für SchwerhörigengeräteCerumen trap for hearing impaired devices
Die Erfindung betrifft einen Cerumenfänger für Schwerhörigengeräte gemäß dem Oberbegriff des Patentanspruches l .The invention relates to a cerumen trap for hearing impaired devices according to the preamble of claim 1.
Derartige Cerumenfänger sind bereits bekannt. Da der Schallkanal zum Gehörgang hin offen ist, kann immer noch Cerumen in den Schailkanal eindringen und damit diesen und die zum Schal lkanal führenden Durch¬ lässe verstopfen . Damit sind aber auch die sternförmig angeordneten Durchlässe blockiert.Such cerumen traps are already known. Since the sound channel is open towards the auditory canal, cerumen can still penetrate the schail channel and thus clog it and the passages leading to the sound channel. However, this also blocks the passages arranged in a star shape.
Aufgabe der Erfindung ist es, einen Cerumenfänger der eingangs genann¬ ten Art so zu verbessern, daß nicht nur das Eindringen von Cerumen mit großer Sicherheit verhindert wird, sondern daß außerdem die immer noch erforderliche Reinigung des Cerumenfüngers erleichtert wird.The object of the invention is to improve a cerumen catcher of the type mentioned at the outset in such a way that not only the penetration of cerumen is prevented with great certainty, but also that the cleaning of the cerumen catcher which is still required is facilitated.
Diese der Erfindung zugrunde liegende Aufgabe wird gemäß den Merk¬ malen des Patentanspruches l gelöst. .This object on which the invention is based is achieved in accordance with the features of patent 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 Ver¬ bindung 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:The figures show:
Fig . I schematisch eine stark vergrößerte Seitenansicht des zylinderförmigen Bauteils für einen Cerumenfänger; Fig. 2 eine Draufsicht auf Fig. 1;Fig. I schematically shows a greatly enlarged side view of the cylindrical component for a cerumen trap; Fig. 2 is a plan view of Fig. 1;
Fig . 3 eine Schnittansicht der Fig . 1;Fig. 3 is a sectional view of FIG. 1;
Fig. 4 eine Kappe, von oben gesehen;Figure 4 is a cap seen from above.
Fig . 5 eine Schnittansicht der in Fig. 4 gezeigten Kappe undFig. Fig. 5 is a sectional view of the cap shown in Fig. 4 and
Fig . 6A und 6B den gesamten Cerumenfänger in zwei verschiedenenFig. 6A and 6B the entire wax collector in two different
Ansichten .Views.
Der in den Figuren gezeigte Cerumenfänger ist sehr stark vergrößert darge¬ stellt, 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 overall.
Fig. 1 zeigt dabei das in ein Hörgerät oder in eine Otoplastik einsetzbare zylinderförmige Bauteil 1 mit einem durchgehenden Schailkanal 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 which can be inserted into a hearing aid or into an otoplastic and has a continuous Schailkanal 2, which carries at its one end an approximately 1.2 mm long connecting piece 3. 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 Bau¬ teil 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 Bauteil 1 angeordnet. 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.As can be seen clearly from FIG. 1 in connection with FIG. 2, the component 1 has several, for example four, angle pieces 4 on its circumference following the connecting piece. Of course, there can only be 3 or more than 4. These angle pieces are arranged evenly on the circumference of component 1. At their upper end, the elbows have locking lugs 5, while a horizontally extending base section 6 is provided at the lower end, the meaning of which will be explained below.
Eine Schnittansicht durch dieses Bauteil 1 zeigt Fig. 3.3 shows a sectional view through this component 1.
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.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 darge¬ stellt. 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 Schal laustritts 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 arrows drawn in both figures clearly show the course of the scarf outlet.
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 the distances between the individual angle pieces 4 and the size of the cavity 9 are selected accordingly, a desired resonance behavior can be achieved in the output of the hearing device.
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 Hohlraumes 9 in geringem Maße variiert werden kann.It can also be seen that the size of the cavity 9 can be varied to a small extent by the choice of the dimensions of the angle pieces and the locking lugs or the location of the locking groove 8 in the cap 7.
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 verhindern wird.It can also be seen that in this new arrangement, the side walls of the cap 7, which overlap the base parts 6 of the angle pieces will certainly prevent the penetration of cerumen.
Dieser Cerumenfänger ist sehr leicht zu reinigen, da die Kappe gut ab¬ nehmbar 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 Sockelteϊl 6 der Winkelstücke 4 eine Kjemm- wirkung erzielt wird .This cerumen trap is very easy to clean because the cap can be removed easily. Nevertheless, the cap normally sits sufficiently firmly on the cylindrical component, since the locking lug 4, which is latched into the locking groove 8 of the cap 7, in conjunction with the bearing of the cap edge on the base oil 6 of the angle pieces 4, achieves a Kjemm effect.
Die Erfindung läßt sich auch durch eine mechanische Umkehrung ver¬ wirklichen . Das Bauteil wäre dann an seiner auf den Gehörgang ge¬ richteten Oberfläche glatt und hä tte an seiner Außenfläche eine Rastnut . Die Kappe 7 würde dann an der Innenwand eine Anzahl von Rastnasen in Verbindung mit einer gleichen Anzahl von Abstands¬ stücken aufweisen . Diese würden dann ebenfalls nicht nur verhindern, daß die Kappe zu tief eingesetzt wird, sondern auch eine Klemmwir¬ kung ausüben . The invention can also be implemented by mechanical reversal. The component would then be smooth on its surface facing the ear 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.
