Definitions

  • the present invention relates to a device for sonication an eardrum that can be inserted into an ear canal is, with a housing that on a facing the eardrum End a substantially cylindrical housing section includes, with a receiver device for output of sound signals, with a sound outlet opening in the Housing on the side of the housing facing the eardrum and with a cerumen protection device, which is in the housing is integrated to protect the handset against through the Cerumen penetrating the sound outlet. Furthermore concerns the present invention a corresponding method for Sonication of the eardrum.
  • the earphones may be contaminated by cerumen. This often leads to failure of the handset in particular of so-called in-the-ear hearing aids (ITE).
  • ITE in-the-ear hearing aids
  • Cerumen protection systems are used so that the cerumen is not without further can reach the listener.
  • Such open wax protection systems can pollute the handset though don't always prevent.
  • a hearing aid with a filter unit.
  • the filter unit is used to protect against cerumen and has a flat, membrane or sieve filter element. If the filter element is inclined, can for the sound an enlarged effective passage area be created, in addition to the constipation or Risk of contamination of the filter element, conditionally due to the inclination and the increased effective area is. Inclination angles between 45 ° and 90 °. In the latter case, the flat filter element lies along the sound center direction.
  • the object of the present invention is therefore a device and a method for sonicating the eardrum propose where disruptive influences by Cerumen occur less.
  • a device for sonicating an eardrum that is in an ear canal can be used with a housing attached to the one End facing the eardrum has a substantially cylindrical shape Includes housing section, one integrated in the housing Handset for the output of sound signals, one Sound outlet opening in the housing on the eardrum facing side of the housing and a wax guard, which is integrated in the housing to protect the Against what penetrates through the sound outlet opening Cerumen, and which comprises a membrane which essentially parallel to the cylinder axis of the cylindrical housing section is arranged and which the sound of the listener Forwarding to the sound outlet opening, whereby the cerumen protection device a receiving device into which the membrane and the receiver are integrated, includes, such that the membrane and the earphone on the eardrum facing Side can be removed from the housing.
  • the handset can thus be protected against intrusion Seal cerumen through the membrane, the area of which is large enough can be chosen so that it is not perceptible Attenuation of the sound emitted by the listener comes. This is due to the fact that the transmission properties larger membranes are better than small ones. On the other hand the large membrane area also has the advantage that it cannot be occupied by cerumen so quickly, so that perceptible damping can be avoided for a long time.
  • the integrated in the housing in the longitudinal direction of the housing Membrane has the advantage of being inserted into the ear canal offers a smaller area of attack than membranes, the plan on the front of the housing, so transverse to the ear canal are mounted. Thus, the risk of tearing when inserting can be reduced.
  • the cerumen protection device comprises a receiving device into which the membrane may be can be plugged in together with the handset.
  • the receiving device should advantageously be arranged in this way be that the membrane and the handset on the the Drumhead facing side can be removed from the housing can.
  • the housing 1 shows a housing 1 of an ITE hearing aid, which the individual Reflects contours of an ear canal.
  • the housing 1 is approximately cylindrical, with that of the eardrum facing housing section 2 to a lesser extent has as the housing section 3 facing the outer ear.
  • the housing 1 On the side facing the eardrum, the housing 1 an end face 4, which, if the hearing aid in the ear is used, runs essentially perpendicular to the ear canal.
  • the end face 4 has an elongated sound outlet opening 5 through which the sound from the earpiece to the eardrum can reach.
  • FIG. 2 shows a cut-open housing 1 into which Handset 6 is installed.
  • the receiver 6 routes the generated one Sound first via a sound tube 7 in a shell or receiving device 8 further.
  • the receiving device 8 has a sound inlet opening 9 the sound tube 7 receives or to which the sound tube 7 is mountable.
  • the shell or receiving device 8 is fixed below the sound outlet opening 5 to the housing 1 on the End face 4 mounted.
  • a membrane 10 can be inserted into the shell 8.
  • the inserted State separates the membrane 10 from the inside of the shell 8 in two parts, the sound inlet opening one part listened and the sound outlet 5 to the other. Further the membrane 10 is opposite in the inserted state the sound inlet opening 9 of the shell 8, and the in the shell 8 incoming sound excites the membrane 10 Vibrations.
  • the membrane 10 transmits the sound in the other part of the bowl so that it passes through the sound outlet 5 can reach the eardrum.
  • the membrane 10 can be used in a suitable Frame can be embedded for cleaning out of the Remove sound outlet 5. Conveniently owns the frame in which the membrane 10 is clamped, on which the Sound outlet opening 5 opposite L-shaped side Extension with which when the membrane 10 is removed also in the gap between the shell wall and the membrane penetrated cerumen can be removed.
  • the housing in the region of the housing section facing the eardrum 2 have a larger diameter than the housing shown in FIG 2.
  • the handset 6 together with the cerumen protection device, which comes from the Shell 8 including the membrane 10 is immediate Arrange below the housing end face 4. So there is a need no sound tube 7 for guiding the sound from the receiver 6 to the membrane 10. Rather, the receiver 6 can directly in the shell or receiving device 8 can be accommodated, so that the listener 6 directly sonicates the membrane 10 can. In this case, the sound outlet opening of the Handset 6 on its side opposite the membrane.
  • the in this second embodiment of the present invention has a removable cover 11 on the underside thereof the shell 8 is attached.
  • the lid can thus the receiver 6 together with the membrane 10 and the Shell 8 can be removed from the hearing aid. With that you can easy to clean both the membrane 10 and the receiver 6 exchange easily.
  • the sound is guided according to the Membrane as in the first embodiment between the membrane and the wall of the shell 8 to the sound outlet opening 5, in the present case through the lid 11, which is in the area of the sound outlet openings slot-shaped passages 12 has, is closed. Ensure the through slots 12 the passage of the sound and prevent the penetration of larger cerumen components into the sound outlet opening 5.
  • the advantage of the second embodiment is that the receiver 6 together with the cerumen protection device 6, 8 as a complete module for exchange or cleaning purposes can be removed. This depends on the handset geometry however only possible with ITE hearing aids, their owners have a sufficiently large ear canal.
