Description

DESCRIPTION

Intra-channel vibrating hearing aid

Object of the Utility model 5

The invention falls within the technical sector of electromedicine devices aimed at the extension and modulation of sound to improve hearing in people with hearing loss.

 10

Background of the invention

Until today, hearing aids base their operation on the capture of sound slings, on the transformation of these into an electric current, on the amplification of this current, on the return to change said amplified current into new waves and on 15 Issue these again.

Current hearing aids can be divided into those that emit the waves again through a headset applied within the ear canal and those that reproduce these sling in the form of vibration to stimulate the inner ear cells through the bone.

Depending on the sound treatment, hearing aids can be classified as:

.- Analog: The amplification of the signal is done mechanically by directly manipulating the amplifier.

.- Digital: Modify the sound in digital signal and once modulated it is passed back to analog.

 30

.- Programmable: in these the digitized signal can be programmed so that the resulting signal is easily adjustable to the patient's needs.

.- Multichannels or multibands, they have several channels and each one in turn of several soundtracks, by means of which they can be programmed independently for each one of the different environmental situations.

.- Automatic, they do not have volume control, they adjust automatically according to the acoustic situations of the environment.

 40

In turn, as the hearing aids are located in relation to the ear, these are qualified in

.- Headphones: They are placed behind the auditory pavilion.

.- Headphone: They are applied at the entrance of the ear canal. Four. Five

.- Intracanales: They are very small and are placed inside the duct at the height of the cartilaginous part.

. -C.I.C, prostheses entirely in the canal, are applied in the deepest part of the ear canal, in their bone part, they are the smallest.

All these use the airway, that is, they reproduce the sound through a headset and it is adapted to the external ear canal.

The prostheses that emit the amplified sound in the form of a vibrating tablet (bone path) may have the microphone on the front of a pair of glasses or on the end of a headband, 5 but the vibrating tablet is always placed on the bone that is found behind the ear, mastoid bone.

There is a variation in this bone pathway and it is to place a titanium screw in the bone and the vibrator (implanted bone hearing aid) is applied to it. 10

The cochlear implants are separated, the implant transforms the acoustic signals into electrical signals and transmits them to the inner ear to stimulate the nerve endings of the cochlear nerve.

 fifteen

The intracanal vibrating hearing aid is always placed inside the external auditory canal and may be in contact with the cartilaginous wall (external) or with the bone walls (internal), this being a deep application of the hearing aid.

Description of the drawings 20

In Figure 1, inside the housing of an intra-channel hearing aid (1) applied to the cartilaginous or bone part of the ear canal and using a pick-up microphone (2), or a coil (6) these will change the sound waves into energy electric and will transmit it to the microprocessor (3). 25

This microprocessor (3) will expand and modulate the output signal by emitting the resulting electrical signal to a vibrator, vibrating pad (4) embedded in the housing (1) that will be in charge of converting the electrical signal into mechanical again.

 30

The electrical energy for its operation is supplied by a battery (8).

It will have a switch (7).

Ear ventilation is guaranteed by a channel within the wall of the housing (5), 35 to avoid the sensation of fullness of the ear when the applied prosthesis is on.

In Figure 2, in a retroauricular housing with sound input (1) to a microphone (2), which transforms the sound signal to electric current that is sent to the microprocessor (3), where it is modified before sending it to the vibrator ( 6), which is in the mold (5), at the entrance or inside the ear canal. The electrical energy for its operation is supplied by a battery (7).

Preferred realization of the utility model

 Four. Five

It is achieved by changing in the current conventional hearing aids, the output speaker for the bone vibrator.

The mold of the external auditory canal and the shell of the pavilion is taken, as is usually done, with it the hard silicone shell is made and in it the vibrating tablet is adapted, instead of the speaker of the conventional hearing aids, this will transmit he

sound to the patient, once modulated and enlarged by the elements of the hearing aid, namely: Microphone ---- Microprocessor ---- Vibrating Pickup.

Claims (3)
