Abstract

THE HEARING AID CONFORMING TO THE INVENTION IS ENTIRELY LODGED IN THE USER'S HEARING CANAL AND, FOR THIS PURPOSE, INCLUDES A SHELL 2 WHICH IS MOLDED FROM AN IMPRESSION TAKEN ON THE USER. THE HULL 2 INCLUDES AN OPENING 3 THROUGH WHICH A SUPPORT IS INTRODUCED INCLUDING THE DIFFERENT KNOWN ELECTRONIC COMPONENTS AND AN OPENING 4 IN WHICH A FILTER 5 IS ENGAGED WHICH ALLOWING THE AMPLIFIED SOUNDS TO GO TOWARD THE TYMPAN, OPPOSES THE PENETRATION OF CERUM , WHICH CAN BE EASILY ELIMINATED BY EASY CLEANING THANKS TO STRAIGHT STRIES 8 PROVIDED ON FILTER 5, THE LATTER CAN BE REMOVABLE OR FIXED.

Description

HEAVY DUTY HEARING PROSTHESIS DEVICE IN THE CONDUIT

AUDITIVE AND ANTI-CERUMEN FILTER

  There are already different types of prosthesis devices

  for people whose ears are defective.

  But these devices do not give complete satisfaction. Even those who are placed outside the pavilion of

  the ear must have a mouthpiece engaged in the duct

  ditif. Now, more is pressed into the ear canal the mouthpiece

  of an apparatus, the more it is exposed to secretions of cerumen.

  The present invention aims to remedy this drawback and allows to fit in the ear canal not only a short mouthpiece but a whole device, personalized since the shell that contains it is made to measure, from

an individual imprint.

  The invention will be well understood from the detailed description of

  Hereinafter with reference to the accompanying drawing. Well

  tense description and drawing are given only as

indicative and not limiting.

  FIG. 1 is a view of a blank of the shell of an apparatus according to the invention showing the opening in front of

receive the anti-cerumen filter.

  FIG. 2 is a schematic view of the support of

Appears.

  FIG. 3 is a schematic view showing the components

  the apparatus placed in the hull, as

feel from the outside.

  FIG. 4 is a schematic view of the set of

  the apparatus according to the invention after adaptation of the

  bauche of the shell to the desired shape.

  According to the invention, an aural prosthesis device is characterized in that its components 1 are all housed in a shell 2 conforming to the internal configuration of the user's ear canal and in that this shell 2, provided with an opening to its two ends 3-4, is equipped with a filterS which is placed opposite the opening 4 to be located in the bottom of the auditory canal and which has a

  passage 6 for sounds amplified by the device.

  According to other features of the invention

  the filter 5 comprises a central passage 6, a crown

  7 and transverse striations 8 leaving behind

  Sister a kind of grid suitable for the transmission of sounds to the vicinity of the tympanum and opposing, at the same time, the penetration of cerumen to the exit of the duct called "earphone", through the opening 4 of the hull 2;

  the filter 5 is removable and entirely placed in a

  extending the hull 2; the filter 5 is irremovable and exceeds the end of the

  shell 2 so that it can be cleaned.

  Referring to the drawing, we see in Figure 1 there

  hull 2 to contain the device itself that is

say the electronic components.

  FIG. 2 shows a support 9 for the components

  electronic devices 1 and which can be cold-processed

  acrylic resin and which is associated with a battery 10, a potential

  sound volume meter 11 and other accessories such as

circuits etc ...

  FIG. 3 presents an embodiment according to which

  a cover 12 is pivotally mounted outside the housing

  seems of the device that is to say on its face which is so-

  killed to the outside of the ear canal and which masks or

  unmask the housing of the battery 10 while leaving

  the potentiometer knob 11 and the outlet of a con-

  duit 13 leading the external sounds to the components of the device and, essentially, to the 3rd amplifier all

known type.

  The shell 2 which must contain the support 9 and the different

  components 1 such as amplifier, microphone,

  earpiece, etc ... is made of noble metal. It is ob-

  held in two stages: - first we take the impression of the auditory canal of the

  who should receive the hearing aid. This em-

  preint is dipped in a silver solution and after cooling, polishes and ensures a surface condition

perfectly smooth.

  - Then this blank is immersed in an electrolyte

  of gold that completes the first silver.

  The filter 5 is engaged by the opening 4 so that

  it is immobilized either by jamming or by screwing

  thanks to a thread with which it is equipped and which corresponds to

a tapping of the opening 4.

  It comprises a central passage 6 and a peripheral ring

  7. At its outer end, it has parts

  transverse which create streaks 8 and this kind of grill

  allows both the passage of sounds from the

  earpiece to reach the eardrum and opposes the penetration of cerumen that could reach the earpiece as this is

  the case with other devices currently known.

  The provision of straight striations 8 allows easy cleaning after removal of the filter 5 out of the opening 4, the streaks also serving as a small screwdriver

  in the case where the filter 5 is screwed.

  According to another variant, the filter 5 could be permanently fixed, but then the parts in which the cerumen can accumulate should be easily accessible.

for cleaning.

  We see that this filter is a kind of cerumen trap and it is much easier to clean such a filter as the inside of a conduit of a headphone such as that of a

ear tip.

  When the hearing aid thus created is complete, it is personalized since its shell 2 is put in the exact shape of the imprint of the ear canal of the user. This

  prosthesis can be adjusted and checked with an artificial ear.

  appropriate because it is executed specifically for each

  person, it has individual acoustic characteristics

  duels known justiciable a precise adjustment.

  The invention is not limited to the modes of

  described and represented, but on the contrary

all variants.
