Definitions

  • the invention relates to a hearing aid that can be inserted into an ear cup with a plastic ear cup part and a peg-shaped ear plug part that can be inserted into the ear canal and that has at least one sound outlet opening at the end, and with electrical components built into the hearing device, namely the microphone, an amplifier, and a receiver , a battery and a volume control.
  • a generic hearing aid is described in DE-36 13 165 C1.
  • the sound tube of the listener opens into the area of a sound outlet opening provided at the end of the ear canal part, which is unprotected, so that it can become clogged with cerumen over time when the device is worn.
  • the hearing aid wearer is trying to manipulate this opening again, due to the small size of this sound outlet opening this is quite difficult, on the other hand the actual hearing aid and the electrical components in the hearing aid are damaged.
  • DE-GM 19 79 669 it is proposed to insert a fitted and exchangeable tube into the end section of the sound channel which is open to the auditory canal. If this tube is dirty and the opening of the tube has clogged, the dirty tube can be pulled out of the end section of the sound channel and replaced with a new tube. This arrangement still irritates the hearing device user to carry out this work himself and thereby damage the device, or it forces the hearing device user to go to a maintenance workshop, which is perceived as annoying.
  • DE-PS 12 59 951 proposes a hearing aid in which a cover part is clipped onto the sound exit opening in the area of the sound exit, this cover part having at least one sound exit opening. In practice, it has been found that the disadvantages that previously existed cannot be avoided by this arrangement, since with the small size of an in-the-ear hearing device the cover plate has only such small openings can get clogged with cerumen very quickly. Here too, replacement is difficult.
  • cerumen protection plate which is constructed in a similar manner to the device according to DE-PS 12 59 951, but which is designed in such a way that the cerumen is released in connection with a special device Protection plate from the hearing aid is possible and that a new cerumen protection plate can then be placed on the device by simply pressing it on.
  • This known device has the disadvantage that, since it is arranged in an easily detachable manner at the outer end region of the auditory canal part, it can also become detached in the ear, for example when the hearing aid is removed, especially when there is a very narrow auditory canal in the ear.
  • the removal of the cerumen protection plate which is then in the ear requires the consultation of a doctor.
  • the remaining gap between the protective plate and the ear canal part is also very small. This promotes cerumen grain formation and leads to rapid constipation.
  • the invention has for its object a protective device for the sound outlet opening of an in-the-ear hearing aid to create that is firmly connected to the hearing aid, so it does not have to be replaced, but on the other hand also gives a layperson and an elderly person the opportunity to quickly remove any cerumen soiling that may be present, thereby ensuring that the performance of the hearing aid is not impaired Cerumen contamination is restricted.
  • This object on which the invention is based is achieved by the teaching of the main claim.
  • cerumen now collects on the end side of the ear canal part, but this cerumen scarcely leads to grain formation tends and can also be easily removed with a small brush, whereby the actual sound outlet opening remains free in the tube section, since this tube section protrudes beyond the end side of the ear canal part.
  • Cleaning the hole provided in the bracket for example with the aid of a needle or a brush, cannot damage the electrical components of the hearing aid which are accommodated in the part of the auditory canal.
  • 1 denotes a hearing aid, which essentially consists of an ear cup part 2 and an auditory canal part 3.
  • the end of the auditory canal part 3 ends in an end side 5 which is essentially flat and in which a through-hole is made.
  • the sound outlet opening is formed by a pipe section 6, for example a plastic hose, which is used as a Sound channel leads in the direction of the eardrum and which protrudes upward beyond the end side 5, so that the through-hole does not come into contact with the brush at all when cleaning the end side 5, for example with a brush.
  • the tube section 6 is overlapped by a bracket 7, which is rounded and thus anatomically correct and which in this embodiment is formed from the wall of the ear canal part in the same material.
  • This bracket 7 has at its apex opposite the sound outlet opening 4 of the pipe section 6 a bore 8 which serves as a sound hole.
  • the ear canal part 3 which is individually adapted to the user, is initially manufactured and the end is then ground flat. This results in an open, flat end side 5.
  • a series-produced element 10, which consists of a base plate 11 with a bracket 7 (FIG. 3), is then glued onto it. At least the through hole 4 can be drilled in the base plate 11 beforehand. Finally, the hole 8 can be made in the bracket. The parts protruding from the end side 5 only need to be sanded.
  • the base plates 11 with bracket 7 can be cast as standard or injection molded from a physiologically harmless plastic.
  • the plastic can be colored in the two audiometric colors, so that the hearing aids for left and right are individualized differently. While this solution brings significant manufacturing advantages and cost savings, it still has minor problems.
  • each base plate 11 with bracket 7 must be cast or sprayed individually.
  • the entire element 10 is colored in its entirety, which makes visual inspection with regard to contamination more difficult and, finally, two differently colored elements 10 must be kept in stock.
  • the design according to FIGS. 4-7 avoids these disadvantages.
  • the ear canal part 3 is again ground flat to form an end side 5. Then not an entire element, but only a colored base plate 11 'is glued. On the base plate 11 'you then glue a bracket 7' made of colorless, transparent plastic.
  • This variant eliminates the disadvantages mentioned above and is particularly suitable for large-scale production. For this purpose, the individual elements are briefly described again.
  • the hearing aid technician thus provides the end face 5 with a quick adhesive, takes the strip 12 at hand and presses the outermost base plate 11 'onto the end face 5. After a few seconds, it breaks off the remaining stiffener along the adjacent predetermined breaking point 13. Now he can easily make the through hole 4 at the marked point 14 and insert the pipe section 6.
  • the bracket 7 'are made for example in the form of strips of 10 pieces contiguously. In this way, a strip of 10 stirrups per injection or casting process can be produced with a simple shape. Such a strip 15 is shown in FIG. 6, the brackets 7 'with the concave curvature being visible upwards.
  • the carrier material 16 between each two adjacent and laterally remaining carrier material serves as a predetermined breaking area.
  • the bracket support surfaces 17, which serve as adhesive surfaces, are excessive.
  • a hearing aid manufactured in this way has all of the aforementioned advantages. It can be produced inexpensively as standard and the base plates can be made in the desired audiometric colors red for the right and blue for the left. With regard to the clear width of the bracket, that is, the size of the curvature, the following dimensions preferably apply: Width about 3.8mm - 5.0mm, minimum height 1.5mm. This mass results from the conditions of the ear canal, as well as from the experience of grain formation in the cerumen.
