Description

Ohreinsatzstück für Hörgerät Die Erfindung betrifft ein Ohreinsatzstück für ein Hörgerät, das nach einer individuellen Ohrmuschel geformt ist und einen in den Ohrkanal hineinreichenden Teil aufweist.Ear insert for hearing aid The invention relates to an ear insert for a hearing aid that is shaped after an individual auricle and one having part reaching into the ear canal.

Es ist bekannt, in einer ein solches Einsatzstück mindestens teilweise erfüllenden nachgiebigen Masse einen Verstärker, einen Schallgeber und einen den Schall von diesem in den dem Ohrkanal angepaßten Teil leitenden Körper einzubetten. Es ist auch schon bekannt, das Ende des in den Ohrkanal führenden Teiles mit einem mit einer Bohrung versehenen, auswechselbaren und nachgiebigen Paßteil zu versehen.It is known in such an insert piece at least partially fulfilling resilient mass an amplifier, a sounder and a Embed sound from this in the adapted part of the ear canal conductive body. It is also known that the end of the part leading into the ear canal with a to be provided with a bore, replaceable and resilient fitting part.

Wenn ein solches Ohreinsatzstück längere Zeit im Ohr getragen wird, so besteht die Gefahr, daß die Absonderungen im Gehörgang wegen des luftdichten Abschlusses des Ohrkanales sich nicht verdicken und sich im Gehörgang ansammeln und so die Schallleitung im Gehörgang beeinträchtigen.If such an ear tip is worn in the ear for a long time, so there is a risk that the secretions in the ear canal because of the airtight End of the ear canal do not thicken and accumulate in the ear canal and thus impair sound conduction in the ear canal.

Um diese Nachteile zu vermeiden, wird gemäß der Erfindung vorgeschlagen, das den Schalleitkanal des Einsatzstückes abschließende Paßstück als Filterkörper nach Art eines Druckknopfes mit einer ringförmigen Einschnürung zur formschlüssigen Verbindung mit dem Schalleitkörper auszubilden. Dieser einen verhältnismäßig engen Kanal aufweisende Filterkörper nimmt die Absonderungen des Gehörganges auf und wird dann von Zeit zu Zeit gegen einen frischen Filterkörper ausgetauscht.In order to avoid these disadvantages, it is proposed according to the invention, the fitting that closes the sound duct of the insert as a filter body in the manner of a push button with an annular constriction for a positive fit Form connection with the sound conductor. This one relatively tight The filter body having the channel absorbs the secretions of the auditory canal and becomes then exchanged for a fresh filter body from time to time.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in schematischer Weise im Schnitt dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown in a schematic manner in section.

Das Ohreinsatzstück besteht aus einem dünnwandigen Gehäuse 1, dessen äußere öffnung mittels einer Platte oder Folie 2 verschlossen ist, die mit einer den luftdichten Abschluß bewirkenden Schicht 20 einer transparenten Dichtungsmasse bedeckt ist. Die Organe des Gerätes, die mittels Schaumgummipolster 3 gelagert sind, bestehen aus Verstärkerteilen 4, dem Schaflgeber 5 und dem mit dem Schallgeber 5 verbundenen, die Schallwellen in den rohrförmigen, in den Gehörgang hineinreichenden Teil 11 des Gehäuses leitenden Körper 6. Am Ende dieses in den Gehörgang hineinreichenden rohrfönnigen, eine öffhung aufweisenden Teiles 11 ist ein auswechselbares Filter7 angeordnet, das mit seinem in den rohrfönnigen Teil 11 hineinragenden Teil eine forinschlüssige Verbindung mit dem Schalleitkörper 6 herstellt.The ear insert consists of a thin-walled housing 1, the outer opening of which is closed by means of a plate or film 2, which is covered with a layer 20 of a transparent sealing compound which creates an airtight seal. The organs of the device, which are mounted by means of foam rubber pads 3 , consist of amplifier parts 4, the sheep transducer 5 and the connected to the sound transducer 5 , the sound waves in the tubular, into the ear canal part 11 of the housing conductive body 6. At the end of this in A tubular part 11 that extends into the auditory canal and has an opening is provided with an exchangeable filter 7 which, with its part protruding into the tubular part 11, establishes a form-fitting connection with the sound-conducting body 6 .

An dem Gehäuse 1, ist ein Federbügel 8 befestigt, der die elektrischen Leitungen zwischen dem Schallgeber 5 und dem nicht gezeichneten Mikrofon aufnimmt.On the housing 1, a spring clip 8 is attached, which receives the electrical lines between the sounder 5 and the microphone, not shown.
