Description

Wax protection device.

Object of the invention

The present Utility Model application Its purpose is to register a protection device anti-wax that incorporates notable innovations and advantages over the current wax filter settings used to The same end.

More specifically, the device of the invention significantly increases the half-life of the filters until now known; facilitates the cleaning of the device by the user avoiding continuous movement to auditory centers; Y considerably reduces breakdowns of acoustic prostheses.

Background of the invention

In the field of hearing aids, wax It is one of the biggest drawbacks. The originated problems by the secretion of wax in the hearing aid can cause damage to the earpiece, loss of acoustic signal that can reach disable the operation of the prosthesis, etc.

Currently, commonly known are known wax filters whose purpose is to minimize problems which causes wax in hearing aids.

However, despite preventing damage from The aforementioned filters have a low average life of between 2 and 4 weeks, in addition to, losses in signal quality acoustic, and effective sound pressure decrease in the channel auditory.

Consequently, the user must change the wax filter by one again with some assiduity. This operation is cumbersome and laborious by the user or hearing impaired, who must end up going to a hearing center specialized.

Description of the invention

The object wax protection device of this register, solve the problems above cited, also providing other additional advantages that will be evident from the description that accompanies continuation.

To do this, and more specifically, said device, applicable to acoustic prostheses, is characterized by the understanding a configuration body noticeably hollow cylindrical, which has a widening at its upper base  perimeter in which a perforated membrane is housed, and that It has at least one hole in its lower base that allows passage of the acoustic signal through the device; and that, in addition, presents along the outer surface of the body some ribs, by way of threading, which facilitate the insertion of the device in the acoustic prosthesis.

And additionally, the body presents lodged in inside a protective element, preferably a foam protection, which allows hearing aid protection in the case of excess earwax

The perforated membrane has a roughness in its surface less than 1.5 microns that minimizes the adhesion of the wax, and a thickness less than 50 microns that prevents the earwax block the sound output.

The cylindrical configuration of the body allows increase bandwidth up to 8 KHz, which makes the device acoustically transparent for the hearing aid. It is due to the minimization of the acoustic mass caused by the section of the perforations that make up the membrane.

According to another aspect of the invention, both the body as the perforated membrane are preferably metal an alloy of stainless steel.

Advantageously, and thanks to the features of the device described, the average life of the protector wax increases significantly compared to filters so far known. The durability of the device of the invention is of up to 16 weeks

Also, cleaning and maintenance of device is easy for the user, just clean with a Simple brush and alcohol or similar product. Thanks to that, the user will avoid continuous movement to the auditory center.

In addition, thanks to the use of the device there is a considerable reduction in hearing aid failures.

To complete the description below is going to be done and in order to help a better understanding of its characteristics, is accompanied by the present specification, of a set of planes in whose figures, illustratively and not limiting, the most significant details of the invention.

Brief description of the designs

Figure 1 corresponds to a view in perspective of the wax protection device according with the characteristics of the invention; Y

Figure 2 corresponds to an elevation view and in section of the device represented in the previous figure.

Description of a preferred embodiment

In view of the commented figures and of according to the numbering adopted, it can be observed in them a preferred but not limiting embodiment of the invention, the which consists of an applicable wax protection device to acoustic prostheses, commonly known as hearing aids.

As shown in Figures 1 and 2, the device is characterized by the fact of understanding a body (1) of substantially cylindrical hollow configuration, which presents in its upper base a perimeter widening in which a perforated membrane (2), and which has at least its bottom base a hole (3) that allows the acoustic signal to pass through Of the device; and that, in addition, presents throughout the outer surface of the body (1) ribs (4), by way of threaded, which facilitate the insertion of the device into the prosthesis acoustics.

Additionally, the body (1) has lodged inside a protection element (5), preferably a protective foam, which allows hearing aid protection in the case of excess earwax.

The perforated membrane (2) has a roughness on its surface less than 1.5 microns that minimizes adhesion of the wax, and a thickness less than 50 microns that prevents the earwax block the sound output.

The cylindrical configuration of the body (1) allows to increase the bandwidth up to 8 KHz, which makes acoustically transparent device for the hearing aid. This is due to the minimization of the acoustic mass caused by the section of the perforations that make up the membrane.

According to another aspect of the invention, both the body (1) as the perforated membrane are made of metal, preferably, a stainless steel alloy.

Advantageously, and in accordance with the characteristics described, the average life of the device wax protection increases significantly compared to filters So far known. Also, cleaning and maintenance of device is easy for the user, just clean with a Simple brush and alcohol, so the user will avoid the continuous displacement to the auditory center.

In addition, thanks to the use of the device there is a considerable reduction in hearing aid failures.

The details, the shapes, the dimensions and other accessory elements, as well as the materials used in the manufacture of the device of the invention may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention nor of the scope defined by the claims included in continuation.
