Definitions

  • the invention relates to a universal ear canal insert for a hearing aid. Furthermore, the invention relates to a Hearing aid unit with the universal auditory canal insert and a hearing aid device portable in the ear, or an adapter piece.
  • From DE 199 08 854 C1 is an ear canal insert for hearing aids known, consisting of one of a sound channel interspersed elastic body, in the way of the sound channel has a Cerumenschutz and on to the auditory canal directed part of the sound channel can be placed. It exists the body is made of one core and one core at least partially comprehensive coat, being between the core and the Part consists of a latchable connection and wherein in the Body of cerumen protection is integrated.
  • a disadvantage of the known ear canal insert is that this for holding and fixing a hearing aid tight on the tissue surrounding the ear canal. This will be phenomena known as "occlusion effect" (feeling of pressure in the Ear, alienation of one's own voice).
  • the object of the present invention is an ear canal insert specify that is universally applicable and nevertheless offers a high wearing comfort. It is also a task of the present invention, a universal and comfortable Hearing aid unit to be worn with a universal Auditory canal insert and a hearing aid.
  • the task concerning the use of auditory canal is solved through a universal soft-elastic ear canal insert for a hearing aid with a worn in the ear canal projecting into the ear canal, not the auditory canal sealing, at least substantially cylindrical first section with a diameter in the range of 4 mm to 7 mm, and with an adjoining, in one area the auditory canal entrance, but outside the actual Ear canal closely fitting, at least substantially funnel-shaped or cup-shaped second portion.
  • a hearing aid unit with a universal Ear canal insert and a universal, in the ear portable hearing aid wherein the hearing aid at least partially inserted into the ear canal insert.
  • a hearing aid unit with a universal ear canal insert and an adapter piece for receiving a sound tube one behind the ear portable hearing aid wherein the adapter piece at least partially inserted into the ear canal insert.
  • the auditory canal insert Due to the special design of the auditory canal insert according to the invention this is in its cylindrical first part not close to the ear canal surrounding tissue. In particular, no pressure on the of Bony or cartilaginous tissue surrounded part area the auditory canal is exerted, the occlusion effect is opposite conventional hearing aids or earmolds strong reduced. Furthermore, by the most punctual and non-pressurized edition of this first portion of the tissue Skin irritation in the ear canal largely avoided.
  • the actual sealing of the ear canal takes place at the Ear canal insert according to the invention, although also as in known auditory canal insertions in the area of the auditory canal entrance, but already outside the actual ear canal in the transition region to the outer ear, which is opposite to the usual Diameter of an ear canal, which is between 5 and 7 mm is already greatly expanded. In this area is the ear is relatively insensitive to pressure.
  • the easy deformability of the ear canal insert anyway only a small pressure on the ear exercised.
  • the easy deformability of the auditory canal insert does not become in the sealing area through the relatively hard housing shell of the hearing aid with special needs.
  • ear canal insert In the ear canal insert according to the invention, a special for the connection with this designed, universal, used in the auditory canal portable hearing aid become.
  • This also has a cylindrical front Partial area, which is detachable in the first part of the Ear canal insert is introduced and with this preferably is frictionally connected.
  • the hearing aid can be covered with the ear canal, so to speak.
  • One frequent replacement of the ear canal insert e.g., daily
  • an adapter piece for Connection with a behind the ear portable hearing aid insert is in the cylindrical first portion of the ear canal insert preferably attached frictionally. At its rear end it points Adapter piece Means for attaching a sound tube on, at the other end with the behind the ear portable Hearing aid is connected.
  • an adapter piece and behind the Ear-portable hearing aid consists only of universal usable and inexpensive units.
  • One after the individual anatomical conditions of a hearing aid wearer manufactured earmold is not required. Consequently also result in this application form the already mentioned Benefits of ear canal insertion.
  • FIG. 1 shows a longitudinal section of a housing shell 4 a screwed in the ear hearing aid (IdO) screwed Ear canal insert 1 according to the prior art.
  • IdO ear hearing aid
  • One on one proximal ear canal pin 4 'of the housing shell 4 via a Screw 7 and one or more threads 7 ' screw-on auditory canal insert 1 consists of a body, formed by a core 5 and a firmly attached thereto Mantle 6.
  • a sound channel 2 before which directed to the eardrum Sound channel opening a wax guard 3 is provided.

  • the well-known auditory canal insert seals thus the auditory canal 8 in the region of the auditory canal entrance within of the ear canal 8 from. This becomes one of the hearing aid wearer as unpleasant pressure on the the auditory canal 8 surrounding tissue 9 exerted. Further will be produced as an occlusive effect phenomena generated.
  • FIG. 2 shows an embodiment of an ear canal insert 10 according to the invention.
  • This has a cylindrical front portion 11, located in the ear canal 21st a hearing aid wearer is located.
  • the diameter of the The ear canal of an adult human is usually in Range between 6 and 8 mm.

  • To the cylindrical first portion 11 closes in the Embodiment according to Figure 2 cupped trained second portion 12, whose largest diameter 10 mm exceeds.
  • the sealing of the ear canal by the ear canal insert 10 thus takes place in a region 22 of the ear, which lies in front of the actual auditory canal 21.
  • a universal, i. not individual anatomically shaped in the ear portable hearing aid 15 arranged with the ear canal insert 10 forms a hearing aid unit. This too has a cylindrical front portion, the at the cylindrical first portion of the ear canal insert 10 is tight. This causes the ear canal insert 10 and the hearing aid 15 frictionally with each other connected.
  • the hearing aid 15 according to the embodiment includes a battery compartment cover 16, a Volume control 17 and a pull-out aid 18 to pull out of the hearing aid 15 from the ear. Also the ear canal insert 10 is provided with a pull-out aid 14.
  • a sound outlet 19 with several sound outlet openings.

  • the hearing aid unit with the ear canal insert 10 and the hearing aid 15 forms a very small and compact Unit universally used by many hearing aid users can be worn. There is no pressure on the ear canal 21 surrounding tissue 23 is exercised, the hearing aid unit has a high wearing comfort. Furthermore, this is also caused by worn in the ear hearing aids Occlusion effect relatively weak.
  • FIG 3 Another application of an auditory canal insert 10 according to the invention is shown in FIG 3. Also in this case, the Ear canal insert 10 a front first cylindrical Part area 11 and a cup-shaped rear portion 12 on. The cylindrical portion is located in the through the surrounding tissue 23 formed auditory canal 21. Also From this embodiment, it can be seen that the Ear canal insert 10 in the ear canal 21 is not tight. The sealing of the ear canal 21 also takes place in this case an area 22 of the ear in which the ear canal already in the outer ear passes.
