Definitions
- the invention relates to a cerumen protection device for the sound outlet opening on housings or ear molds of hearing aids, a perforated cap being attachable to a sound outlet nozzle.
- the utility model DE-U-19 51 165 already discloses an in-the-ear hearing device in which a cylindrical body can be placed on the sound outlet connector and has a chamber-like extension of a through-hole in its interior, in which a layer of porous, sound-permeable Material is arranged.
- the sound coming into the through-hole from the receiver of the hearing aid can therefore pass through the layer of porous material well.
- Earwax (cerumen) which is secreted inside the ear canal, cannot reach the inside of the hearing aid in the opposite direction due to the porous layer.
- a comparable arrangement is also shown in DE-B-12 63 849.
- DE-U-84 36 783 and 85 04 765 also provide perforated caps which can be applied to the sound outlet either directly from an in-the-ear hearing aid or an ear fitting of a behind-the-ear hearing aid which can be inserted into the ear (eg attachable or screwable).
- the perforated caps ensure unimpeded sound emission. Earwax, which is secreted in the ear canal, is largely kept away from the openings, since due to the formation of niches etc. there are relatively long creepage distances.
- the object of the present invention is to provide a device of the type mentioned which is much easier to clean when contaminated with ear wax and which at the same time prevents moisture, in particular sweat, from the ear canal through the respective opening into the hearing aid can reach.
- the microporous membrane made of non-stick material also prevents ear wax (due to the very small pores) and moisture, especially sweat (due to the membrane being made of non-stick material) from entering the hearing aid.
- Non-stick material does not let sweat drops become flat, so that the drops cannot penetrate into the micropores. Because of the non-stick effect, the ear wax can be removed more easily than before, for example with the help of ultrasound.
- a membrane made of polytetrafluoroethylene has proven to be particularly suitable for the present purpose.
- the in-the-ear hearing device comprises a housing 1 with a sound output connector 2 and a front cover 3.
- a receiver 4 can be seen, which is connected on the output side to the sound output connector 2.
- a battery compartment 5 (without an inserted battery) can be seen, which can be swiveled out of the hearing aid by means of the cover 6 on the end cover 3.
- the number 7 indicates a microphone and the number 8 the amplifier electronics of the hearing aid.
- the code number 11 denotes the sound entry opening in the end cover 3 for the microphone 7.
- both the opening of the sound outlet connector 2 and the sound inlet opening 11 are covered with a device according to the present invention.
- the device comprises, for example, a screw-on cap 12, while a snap-on cap 13 sits on the sound inlet opening 11.
- Both caps 12 and 13 each include a microporous polytetrafluoroethylene membrane 14 available under the trade name GORE-TEX® for sealing the respective opening against wax and sweat, both of which are secreted in the ear canal.
- the membrane 14 used in each case is, however, very well permeable to the respectively emerging or entering sound.
- FIGS Various embodiments for the caps used in each case are shown in FIGS.
- FIG. 2 shows an exemplary embodiment of a behind-the-ear hearing device with a housing 14 'which can be fastened behind the ear by means of carrying hooks 15.
- a rotary knob 16 for adjusting the volume and a cover 17 for a battery drawer which can be pivoted out of the housing are again indicated.
- the carrying hook 15 is connected to an ear fitting 19 via a sound tube 18.
- a cap 12 according to the present invention is again seated on the sound output opening 20 of the earpiece 19.
- an outsourced earpiece 21 is seated in a housing 22 which can be inserted into the ear canal.
- the output of the outsourced earpiece 21 is connected to the sound outlet connection 23, the opening 24 of which is in turn covered by a cap 12 according to the present invention.
- the electrical connecting lines between the outsourced earpiece 21 and the BTE or pocket device, not shown, are indicated in FIG. 3 by 25.
- FIGS. 4 to 11 show a total of four different embodiments for caps 12 which can be screwed on to sound outlet connectors, one above the other in a cross section and in an end view.
- Figures 12 and 13 show a corresponding arrangement of a cap 12, which is based on an undercut on the sound outlet connection, as it is e.g. are also described in the two German utility models DE-GM 84 36 783 and DE-GM 85 04 765, are attachable.
- FIGS. 14 and 15 show a corresponding arrangement for a cap 13 for insertion into the sound entry opening 11 for the microphone 7 on the front cover 3 of a hearing aid.
- FIGS. 16 and 17 finally show a corresponding arrangement in which a cap according to the invention can in turn be plugged into an undercut, this cap now protecting a sound outlet and a ventilation hole at the same time.
- the cap is 12.1 in FIGS. 4 and 5, 12.2 in FIGS. 6 and 7, 12.3 in FIGS. 8 and 9, 12.4 in FIGS. 10 and 11 and 12, 13 in FIGS designated 12.5.
- the cap of FIGS. 16 and 17 has the reference number 30.
- caps 12.1 to 12.4 thus have an internal thread 31.
- the caps in FIGS. 4 to 9 also include a single central opening 32 on the front side.
- the caps in FIGS 13 to 13 comprise individual small holes 33.
- the caps of FIGS. 12 and 13 do not comprise an internal thread, but rather a circumferential bead 34 which fits into the respective undercut on the sound outlet connector of the respective hearing aid or earpiece.
- the sound outlet connector is indicated at 35 and the ventilation hole at 36.
- the cap 30 comprises holes 37 and holes 38 for the opening of the sound outlet connector 35 and the ventilation hole 36.
- the cap 30 is again provided with a circumferential bead 39 which fits into the indicated undercut 40.
- the cap 13 of Figures 14 and 15 includes one outer annular groove 41 which engages in the opening edge 11 when the cap is inserted into the sound opening.
- a microporous polytetrafluoroethylene membrane 14 which is available under the trade name GORE-TEX® is now used, as already mentioned above.
- the individual membranes are again labeled 14.1 to 14.7.
- the membrane 14.4 or 14.5 is again inserted or fastened into the respective cap 12.4 or 12.5 in a manner similar to that in FIGS. 4 and 5.
- the membrane 14 used in each case is well permeable to sound, but protects the hearing aid used in each case against the penetration of both ear wax and moisture, in particular sweat from the ear canal. Since sweat is kept away, sensitive components of the hearing aid are not at risk of being damaged by corrosion or the like. exposed.
- the membrane material used is water-resistant to 0.65 bar and can therefore also be cleaned in an ultrasonic bath if required, without the need for sensitive electronic components Hearing aid, especially the handset, are damaged. It is no longer necessary to completely replace caps as before; the cerumen-soiled cap can therefore remain on the hearing aid.
