Es sind bereits Vorrichtungen zur Verbesserung des Gehörs bekannt, bei welchen ein kegelförmiger Hohlkörper Verwendung findet, an den ein zweiter kleiner Hohlkörper angeschlossen ist, der sich gegen den Steigbügel der Gehörknöchelchen legt. Bei diesen bekannten Vorrichtungen kam es leicht vor, daß die Durchlochung des Trommelfells nicht völlig durch die Vorrichtung abgeschlossenThere are already devices for improving hearing are known in which a conical hollow body is used to which a second small hollow body is connected, which lies against the stapes of the auditory ossicles. With these known devices it easily happened that the perforation of the eardrum was not completely completed by the device
ίο wurde, weil sich die Übergangsstelle zwischen den beiden Hohlkörpern infolge des hier vorhandenen scharfen Winkels nicht dem Trommelfell anpaßte, und ferner war es ein Übelstand der bekannten Einrichtung, daß das abgerundete geschlossene Ende des kleineren Hohlkörpers infolge seiner Rundung nicht die genügende Anlagefläche zu einem sicheren Halten des Steigbügels bot. Diesen übelständen soll gemäß der Erfindung dadurch abgeholfen werden, daß man zwischen den beiden Hohlkörpern eine schräg verlaufende und mit einer Auskehlung versehene Übergangswandung schafft, welche sich, eng an das Trommelfell anlegt, und daß man dem geschlossenen Ende des kleineren Hohlkörpers eine möglichst große Abflachung gibt, so daß diese eine verhältnismäßig große Auflagefläche für den Steigbügel bildet.ίο was because the transition point between the two hollow bodies not the eardrum due to the sharp angle present here adapted, and further it was a drawback of the known device that the rounded closed end of the smaller Hollow body due to its rounding does not have sufficient contact surface for a safe Holding the stapes bot. According to the invention, this is intended to result in these evils be remedied that there is an oblique between the two hollow bodies and creates a fluted transition wall that fits snugly the eardrum applies, and that one of the closed end of the smaller hollow body there is as large a flat area as possible, so that this has a relatively large bearing surface forms for the stirrup.
Auf der Zeichnung ist die neue Vorrichtung in den Fig. 1 und 2 in Ansicht und im Schnitt dargestellt, während Fig. 3 die Benutzung der Trompete veranschaulicht.In the drawing, the new device is in Figs. 1 and 2 in view and in Section shown, while Fig. 3 illustrates the use of the trumpet.
Der Gehörgang ist mit A, das Trommelfell mit B und die Gehörknöchelchen sind mit C bezeichnet. Die Vorrichtung ist zweckmäßig aus Gummi hergestellt und besteht aus einem kegelförmig verlaufenden Teil D1, welcher in einen ausgekehlten Teil d überläuft und in einen hohlen Ansatz JD2 von bedeutend kleinerem Durchmesser als der Teil D1 endet. Der Teil D2 ist am Ende abgeschlossen und bildet eine ebene Fläche d1, welche dem Steigbügel ein möglichst großes Widerlager bietet. Infolge der kegelförmigen Gestaltung kann sich der Teil Z)1 in dem Gehörgang festsetzen. Wenn man ein geeignetes Instrument in das offene Ende d2 einführt, so vermag man die Vorrichtung leicht aus dem Ohr herauszunehmen. Da man die Vorrichtung zwischen den Teilen D1 und D2 schräg und ausgekehlt gestaltet, kann man sie leichter in die Durchlochung des Trommelfells einführen und diese ohne Unbequemlichkeit für den Benutzer gut verschließen.The ear canal is labeled A, the eardrum is labeled B and the ossicles are labeled C. The device is expediently made of rubber and consists of a conically extending part D 1 , which overflows into a fluted part d and ends in a hollow extension JD 2 of significantly smaller diameter than part D 1. The part D 2 is closed at the end and forms a flat surface d 1 , which offers the stirrup the largest possible abutment. As a result of the conical design, the part Z) 1 can get stuck in the ear canal. If a suitable instrument is inserted into the open end d 2 , the device can easily be removed from the ear. Since the device is designed obliquely and fluted between the parts D 1 and D 2 , it can be inserted more easily into the perforation of the eardrum and it can be closed well without inconvenience for the user.
