Definitions

  • the invention relates to a cerumen trap for hearing impaired devices according to the preamble of claim 1.
  • cerumen traps are already known.
  • DE - B 1 259 951 a hearing device with a protective device against the penetration of cerumen into the interior of the hearing device.
  • a U-shaped component is inserted into the sound output channel of the hearing aid, which has two lateral sound passages.
  • the component has a base into which the pin of a cover that covers the sound output to the outside is inserted in a snap-in manner.
  • the cover On its inner surface, the cover has four webs offset from one another, which, in conjunction with the passages, form the sound output of the device.
  • the object of the invention is to provide a cerumen catcher of the type mentioned at the outset, in which the penetration of cerumen is prevented with great certainty, and also closing the sound outlet at high cerumen pressure is avoided, while the still necessary cleaning of the cerumen trap is facilitated.
  • the cerumen trap shown in the figures is shown on a very large scale. In reality, it has a diameter of almost 4 mm.
  • FIG. 1 shows the cylindrical component 1 that can be inserted into a hearing aid or into an otoplastic and has a continuous sound channel 2, which carries an approximately 1.2 mm long connecting piece 3 at one end.
  • these dimensions are in no way to be interpreted as restrictive.
  • the component 1 has several, e.g. four elbows 4. Of course, there can only be 3 or more than 4. These angle pieces are arranged uniformly on the circumference of the component 1.
  • the elbows At their upper end, the elbows have latching noses 5, while a horizontally extending base section 6 is provided at the lower end, the meaning of which is explained below.
  • FIGS. 4 and 5 show a sectional view through this component 1
  • the cap 7 shown in FIGS. 4 and 5 can be placed on this component.
  • the cap 7 has on its inner vertical surface a preferably, but not necessarily, all-round locking groove.
  • FIGS. 6A and 6B show the new cerumen trap in a side view, partly in section, and in a view from above. It can now be clearly seen that a cavity 9 is formed between the upper edge of the component 1 and the underside of the cap 7. The course of the sound outlet is clearly shown by the arrows drawn in both figures.
  • This cerumen catcher is very easy to clean because the cap is easily removable. Nevertheless, the cap normally sits sufficiently firmly on the cylindrical component, since a locking effect is achieved by the locking lug 4 which is latched into the locking groove 8 of the cap 7 in conjunction with the support of the cap edge on the base part 6 of the angle pieces 4.
  • the invention can also be implemented by mechanical reversal.
  • the component 1 would then be smooth on its surface facing the auditory canal and would have a locking groove on its outer surface.
  • the cap 7 would then have a number of latching lugs in connection with an equal number of spacers on the inner wall. These would then not only prevent the cap from being inserted too deeply, but would also have a clamping effect.

Abstract

Un piège à cérumen pour prothèses auditives comporte un canal de son autour duquel sont agencées selon une configuration étoilée une pluralité de perforations qui relient la sortie de son d'un écouteur avec le canal de son. Un élément cylindrique (1) pourvu d'une tubulure de raccordement (3) entourant le canal de son peut être introduit dans la prothèse auditive. Un certain nombre d'éléments d'angle (4) dotés de taquets d'encliquetage (5) sont disposés à la périphérie de l'élément (1). L'ouverture (2) de sortie de son peut être fermée de l'extérieur par un capuchon (7) qui présente une rainure d'encliquetage (8) ménagée sur la paroi intérieure, et qui s'encliquette sur les taquets d'encliquetage (5).

Claims (4)

  1. Piège à cérumen pour prothèses auditives comprenant un élément (1) à mettre en place dans le canal d'audition de celui-ci et un capuchon (7) recouvrant l'ouverture de passage des sons (2) vers l'extérieur ainsi que plusieurs passages pour les sons, caractérisé en ce gue l'élément (1) est de forme cylindrique avec un raccord (3) entourant l'ouverture de passage des sons (2), élément présentant sur son pourtour plusieurs pièces coudées (4) munies de talons à crans (5) et de portions de socle (6) dirigées vers l'extérieur dans le sens radial, en ce que le capuchon (7) fermant vers l'extérieur l'ouverture de passage des sons (2) de l'élément (1) présente, à sa paroi intérieure verticale, une rainure (8) pour l'enclenchement du capuchon (7) sur les talons à crans (5) des pièces coudées (4) et prend appui sur les portions de socle (6) et en ce que les espaces entre les pièces coudées (4) et le capuchon (7) constituent des passages pour les sons (10).
  2. Piège à cérumen pour prothèses auditives selon la revendication 1 caractérisé en ce que les talons à crans (5) sont disposés à l'extrémité supérieure des pièces coudées (4), si bien que le capuchon (7) reposant sur les portions de socle (6) forme avec l'élément (1) une cavité creuse (9).
  3. Piège à cérumen pour prothèses auditives selon la revendication 2 caractérisé en ce que le capuchon placé sur l'élément cylindrique forme avec la cavité et avec les passages pour les sons (10) figurant entre les pièces coudées (4) une cavité résonnante.
  4. Piège à cérumen pour prothèses auditives selon la revendication 3 caractérisé en ce que les pièces coudées (4) sont disposées à équidistance sur le pourtour de l'élément (1).
