Definitions

  • the invention relates to a method and a device for producing an ear impression and for further processing the ear impression into an otoplastic.
  • the object of the present invention is to provide a method and a device by means of which an ear impression of this module can be produced directly in the ear and the associated otoplastic for an in-the-ear hearing aid module with a cover in an optimally simple and rapid manner.
  • the hollow stamp and the through-channel in the cap allow an ear impression to be made with the stamp inserted, which later mimics the in-the-ear hearing aid module, including the outer shell and cap directly in the ear canal, as excess ear impression material can flow into the interior of the hollow plunger via the through channel of the cap. This prevents excess ear impression material from being pushed into the posterior ear canal.
  • an impression directly in the ear canal is of particular advantage since it reflects the tissue contours particularly precisely with regard to the later in-the-ear hearing aid module to be used together with an otoplastic. With the normal impression method, i.e.
  • an ear impression is obtained that only reflects the relieved situation of the tragus and auditory canal, which only approximates the situation (due to the inserted hearing aid module).
  • the otoplastic to be produced from the negative of an ear impression produced according to the invention in accordance with the features of claim 2 is thus more realistically adapted to the actual conditions of the ear canal than an otoplastic manufactured according to the normal impression method.
  • a stamp 1 comprises e.g. made of plastic, a hollow interior 2 and screw holes 3 at the distal end. Screws 4 fit into the screw holes 3. By means of these screws 4, a plate 5 corresponding to the end face (faceplate) with a stem 5 ⁇ and a vent hole 5 ⁇ can be screwed through holes 6 at the distal end of the stamp.
  • the stamp 1 comprises a nozzle 7 which, after a cover 8 has been placed over it, at least partially protrudes from a proximal hole 9 of the cover 8.
  • a plastic cap 10 which contains a central through-channel 11 for connection to the hollow interior 2 of the stamp 1, is fastened on the part of the nozzle 7 protruding from the hole 9.
  • the hearing aid of a hearing impaired person is injected with an ear impression material (eg silicone compound) after inserting a tampon.
  • an ear impression material eg silicone compound
  • stamp 1 with screwed-on plate 5 with handle 5 1, cover 8 and cap 10 is then carefully inserted into the ear impression material in the ear canal.
  • the outer shell 8 was coated with a suitable adhesive (for example a silicone resin with a volatile solvent, such as, for example, Athesive Permagum), which is intended to facilitate the adhesion of the ear impression material to the outer shell.
  • Displaced ear impression material is pressed in the distal direction, partly directly from the ear canal and partly through the passage 11 of the cap 10 into the hollow interior of the stamp 1, where it remains as a relatively soft plastic (non-adhesive) material after crosslinking.
  • the displaced air can escape from the vent hole 5 ⁇ .
  • Superfluous Ear impression material is therefore not pushed towards the inner ear. Because of the cap, there is a central opening later in the otoplastic that is still to be produced, which ensures that when the in-the-ear hearing aid module is plugged in, its sound outlet opening is always at a certain minimum distance from the skin tissue in the ear. This ensures optimal acoustic coupling to the inner ear.
  • FIG. 2 An example of such an ear impression 12 is shown in FIG. 2.
  • the ear impression material has the reference number 13, the tampon is marked with 14.
  • the stem 5 ⁇ of the component combination of FIG. 1 enclosed in the ear impression 12 protrudes from the ear impression 12.
  • a fixing star 16 can be screwed onto the cleaned ear impression 15 by means of the screws 4.
  • the fixing star 16 comprises stepped star tips 17.
  • the fixing star 16 fits into a star-shaped recess 18 in a holding plate 19 according to FIG. 4.
  • the fixing star 16 together with the cleaned ear impression 15 can be inserted into the recess 18 of the holding plate 19 in such a way that the star tips protrude somewhat from the holding plate.
  • the arrangement in FIG. 5 is placed (if necessary after previous immersion in wax) in a round casting mold 20 which is open on both sides and then, as indicated in FIG. 6, is cast with negative casting material 21 to produce a negative of the ear impression 15.
  • the negative casting material 21 can be gypsum or a silicone.
  • FIG. 7 The finished negative after removal of the ear impression together with the holding plate is shown in FIG. 7. It can be seen that the star tips 17 have left fixing depressions 23 in the negative impression.
  • an outer shell 27 is in turn pulled over a stamp 24, to which a fixing star 25 is screwed by means of screws 26, in such a way that the connector 28 of the stamp 24 projects at least partially from the proximal hole 29 of the outer shell.
  • a cap 30 is pulled over the neck again.
  • the stamp 24 with the outer shell 27 and also the fixing star 25 correspond exactly to the corresponding components 1, 8 and 16, which had also been used to obtain the ear impression or the negative of the ear impression.
  • the previously used parts can be reused, provided that after the negative has been produced, the stamp 1 together with the outer shell 8 are freed from the earprint material.
  • the cap 30 differs from the cap 10 in that it does not include a through-channel. The very thin otoplastic material must not penetrate into the hollow interior of the stamp 24. It would penetrate into cracks between the stamp and the outer shell or also the fixing star and glue them together, so that the stamp could no longer be removed from the outer shell.
  • the negative 22 of the ear impression is now filled with liquid otoplastic material 31 (e.g. polymethyl methacrylate, such as acrylic PMMA), as indicated in FIG. 9.
  • liquid otoplastic material 31 e.g. polymethyl methacrylate, such as acrylic PMMA
  • the part 32 of FIG. 10 composed of the components of FIG. 8 is screwed into the liquid otoplastic material 31 located in the negative 22.
  • the correct end position is achieved in that the tips 33 of the fixing star 25 are brought into agreement with the position of the fixing troughs 23.
  • the part 32 is now in exactly the same position as in the ear canal.
  • the blank 34 according to FIG. 11 can be removed.
  • the fixing star 25 including any protruding otoplastic material along the line a-a is then detached from the blank. Accordingly, the otoplastic material is removed at the proximal end along the line b-b up to the end face of the cap 30.
  • the cap 30 can now be levered out using a fine screwdriver.
  • the proximal hole 28 of the outer shell 27 lies essentially centrally in the finished otoplastic 35.
  • the diameter D of the proximal opening 36 of the otoplastic material 31 corresponds to the diameter of the cap 30.
  • the smallest diameter D is still so large that a cerumen lid 37 with the diameter D1 can be inserted into the proximal opening 36.
  • the cerumen lid 37 comprises an internal thread 38, which according to the FIG. 12 fits the external thread 39 of a proximal threaded connector 40 of an in-the-ear hearing aid module 41.
  • the in-the-ear hearing aid module 41 can now be inserted into the hollow interior 42 of the finished otoplastic 35 until the proximal threaded connector 40 projects through the hole 28 into the proximal opening 36 of the otoplastic material 31.
  • the cerumen lid can then be screwed onto the threaded connector 40.
  • the in-the-ear hearing aid module 41 thus sits firmly and acoustically close to the finished earmold 35.
  • the cerumen lid 37 has 43 sieve-like openings 44 on its end face. It serves as a fixed element for the hearing aid module and as a cerumen trap.
  • the in-the-ear hearing aid module 41 comprises an adjustment button 46 for a volume control on the end face 45, which is also an on and off switch for the device, a further actuator 47, a charger 48 for a battery and a Opening 49 for the sound supply.
