Description

  • The present invention relates to an acoustic hearing aid for the rehabilitation of patients with partial sensorineural hearing loss.
  • Currently, acoustic hearing aids available on the market are categorized into two product categories: earloop devices and in-ear devices.
  • Boundary devices, such as the one shown in the document EP 1 011 295 , comprise an arc-shaped housing intended to be housed behind the ear, this housing generally containing one or more sensors such as microphones, a power source of the battery or battery type, and electronic circuits of amplification and analog and / or digital signal processing. The electronic circuits generate a sound signal that is sent into the ear canal of the patient via an acoustic tube held in the ear canal by an ear plug.
    This in-ear plug also makes it possible to reduce acoustic feedback phenomena between the earpiece and the point of sound emission.
  • In addition to the fact that devices with earloop are standardized, these devices have great ease of implementation, good reliability and sufficient performance, due in part to the relatively large volume available, to integrate all the electronic circuits required. However, these devices have the disadvantage of being painful to wear, and risk falling as a result of certain movements of the head. In addition, they are relatively visible and lack aesthetics. They do not completely eliminate the feedback phenomena because the microphone is relatively close to the earpiece, which forces them to be set to under-amplification mode. In addition, the intra-auricular plug also has drawbacks, including unpleasant feeling of clogged ear, perception of noise during mastication, and hygiene problems and potentially infections, due to the fact that mouth the auditory canal.
    With regard to the second category of devices available on the market, in-ear devices are in the form of small housings intended to be inserted directly into the external auditory canal. This case consists of a resin shell, whose shape is adapted by molding to the anatomy of the external auditory canal of each patient. This box brings together in a very small volume the sound sensor, the electronic circuits for amplification and signal processing, the earpiece, the power source (electric battery). Compared to devices with earloop, they have the advantage of being significantly less visible and compact. In return, they generate significant feedback phenomena, both mechanical and acoustic, due to the proximity of the microphone and the earpiece, which forces them to be set in a mode of sub-amplification even lower than the devices. at the ear. The miniaturization of the microphone and the earphone do not make it possible to obtain sound qualities of good quality.
    In addition, the low volume available makes it difficult or impossible to add additional microphones or more sophisticated signal processing functions. It has a low autonomy due to the use of a battery necessarily small. Because of its small size, handling, especially during settings and battery changes is difficult, which leads to the risk of falling when removed from the ear canal. As for devices with earloop, they cause unpleasant feelings of clogged ear, pose hygiene problems, with risks of infection and premature wear of the device.
  • The present invention aims to eliminate these disadvantages. This objective is achieved by the provision of an acoustic hearing aid device, generating at least one audible signal and intended to be fixed on the body of a patient, this device comprising an external housing enclosing an electronic signal processing module connected at the input to at least one microphone and output to an earphone adapted to emit a sound signal in the external auditory canal 5 of the patient, and a source of energy.

  • A preferred embodiment of the invention will be described hereinafter, by way of non-limiting example, with reference to the appended drawings in which:
    • The figure 1 shows schematically in partial profile view, the head of a patient equipped with a hearing aid according to the invention;
    • The figure 2 represents a sectional view of a portion of the patient's head shown on the figure 1 equipped with the hearing aid according to the invention;
    • The figure 2a is an axial view of an in-ear earphone holder, according to the invention;
    • The figure 3 shows in more detail the prosthesis shown on the figure 1 and the device for fixing the prosthesis according to the invention;
    • The Figures 4 to 6 show three variants according to the invention of the device shown in detail on the figure 3 ;
    • The figure 7 shows in section another advantageous variant of the device according to the invention;
    • The figure 8 shows in plan view the device shown on the figure 7 ;
    • The Figures 9 and 10 represent two other variants of the implanted case of the device according to the invention.
  • The Figures 1 and 2 represent respectively in profile view and in section, the head of a patient equipped with a hearing aid device according to the invention, maintained on the skull. This device comprises an external casing 1 equipped with at least one microphone 13a, 13b and enclosing a source of energy, (for example a battery or a battery), and electronic amplification and signal processing circuits, this casing being connected to a device for distributing sound signals in the auditory canal 5 of the patient, this device comprising a earphone 3 and a link 4 between the housing and the inside of the ear canal. As shown on the figure 2 which represents in section the ear 6 and the auditory canal 5 of the patient, as well as part of the skull 7, the case 1 is held according to the invention on the patient's head by means of a magnet housed in a case 2 implanted under the skin and possibly attached to the bone of the skull 7, this magnet being intended to exert a magnetic attraction force on a magnetic part disposed in the outer casing, when the latter is disposed near the implanted casing 2.
  • The housing 2 has a substantially planar shape of small thickness, so as to be inserted under the skin, preferably under the scalp, to be masked by the hair of the patient, even at an advanced stage of baldness. For this purpose, it is implanted for example on the mastoid or on the temporo-occipital bone as represented on the figure 1 .
  • By choosing a magnet whose force is adapted, the housing can be easily attached to the patient's head and maintained in all positions and during normal movements thereof. Functionally, the microphone or microphones on the housing 1 are far enough away from the earpiece, and separated by the horn of the ear that serves as a screen between the reverberated sound from the external ear canal and the microphone. As a result, the acoustic feedback effect between the reverberated sound coming from the external auditory canal arriving on the microphone (s) is very attenuated or even suppressed (depending on the amplification and the opening of the mouthpiece, sought) because of the combination of the two means consisting on the one hand of the sufficient distance between the ear canal and the microphones or microphones located near the temporo-occipital zone, and on the other hand the existence of a natural acoustic barrier formed by the ear pavilion.
  • Thanks to advances in integration of the electronic circuits, the housing 1 may have a small thickness so as not to show an excess thickness when it is masked by the hair.
  • The link 4 between the housing 1 and the earphone 3 is constituted by an electric cable. In this case, the earpiece includes an electroacoustic transducer for insertion into the patient's external auditory canal. Alternatively, this connection 4 is an acoustic tube. In this case, the earphone is integrated in the outer casing 1 and extended by the acoustic tube 4 which is waterproof and has a length adapted to reach the bottom of the external auditory canal of the patient. In this case, the earpiece contained in the housing is equipped with a mechanical anti-feedback damping device (damping vibrations generated by the earphone). It should be noted that there is no phenomenon of acoustic feedback because the sound waves generated by the earphone are channeled through the acoustic tube.
  • Preferably, the cable 4 is semi-rigid so as to accurately follow a predefined path between the housing 1 and the bottom of the external auditory canal, for example by bypassing the ear from above, and keeping the earphone 3 in a certain position. position in the external auditory canal. Thus, it is not necessary to close the ear canal with a plug to hold the earpiece in place.
  • Alternatively, the link 4 may be flexible and the earpiece 3 or the end of the acoustic tube is maintained and centered in the external auditory canal by an in-ear support 9. As shown in more detail on the figure 2a , the in-ear support 9 comprises a central housing intended to receive the earphone 3 or the end of the acoustic tube, this central housing being connected to an outer tubular element 8c by spacers 8a, 8b delimiting with the outer tubular element vents allowing good ventilation of the ear canal. _
  • The tubular element 8c is preferably made of a compressible and / or elastic material, or is molded according to the anatomy of the auditory canal of the patient.
  • Compared to the housings of the prior art, the invention makes it possible to maintain on the patient's head a hearing aid device in an almost invisible manner, only the link 4 remaining visible, while being very discreet. In addition, the virtual absence of feedback makes it possible, on the one hand, to increase the patient's hearing performance thanks to better amplification and, on the other hand, to reduce the problems of hygiene and occlusion phenomenon (sensation of plugged ear) resulting from the quasi-closing ear plug, which can advantageously be replaced by the open ear support 9.
  • As shown in more detail on the figure 3 , the housing 1 encloses a magnetic part 12, for example a ferromagnetic material, which is arranged against a face of the housing so as to be placed opposite and close to the implanted housing 2, when placing the prosthesis on the patient's head. The housing 1 also contains electronic circuits 11 fed by a thin battery (not shown), and a sensor 13 connected to the electronic circuits.
  • Of course, the piece of ferromagnetic material may be housed in the implanted housing 2, and the magnet disposed in the housing 1.
  • In some cases, the sensor 13 must be positioned in a precise orientation relative to the patient's head. In fact, certain hearing aid devices comprise a directional microphone or several omnidirectional microphones which must be oriented so as to restore information on the direction of origin of the sounds, these microphones must be positioned precisely so that the prosthesis can restore sound. exact direction of provenance from perceived sounds.
  • The figure 4 represents a hearing aid housing enclosing two microphones 13a, 13b. So that the housing and therefore the microphones are arranged in a precise orientation relative to the patient's head, the permanent magnet 21 is implanted under the skin so as to have a north-south axis (shown in the figure by the arrow 24) oriented in a certain direction parallel to the surface of the skull. Furthermore, the part 12 housed in the housing 1 is replaced by a magnet 12 ', for example a permanent magnet whose north-south axis 22 is oriented in a predefined direction, parallel to the face of the housing intended to come s' apply against the patient's skin. In this way, the casing 1 can only be held on the patient's head in a certain orientation.
  • This result can also be obtained thanks to the embodiment represented on the figure 5 . In this figure, the permanent magnet 12 ', shown on the figure 4 is replaced by two magnets 12a, 12b whose north-south axes 22a, 22b are oriented perpendicularly to the face of the housing intended to be applied against the skin of the patient, and in opposite directions. In addition, the north-south axes 22a, 22b are spaced apart by a distance corresponding to the distance separating the north and south poles of the implanted magnet 2.
  • The casing 1 can also be held on the patient's head in a certain predefined orientation thanks to the embodiment shown on the figure 6 . In this embodiment, the implanted housing 2 comprises two magnets 21a, 21b whose north-south axes 24a, 24b are oriented perpendicularly to the surface of the skull, and in opposite directions. The housing 1 then encloses a single magnet 12 'as shown in FIG. figure 4 or two magnets 12a, 12b as shown in the figure 5 or 6 these magnets being arranged in the housing so as to face an implanted magnet 21a, 21b respectively, of the same orientation, when the housing 1 is placed in the desired orientation on the patient's head.
  • It can also provide more than two magnets implanted and in the housing. These magnets are arranged so that their respective north-south axes are perpendicular to the patient's skin surface at the location where the housing is to be maintained. In addition, the different magnets must be distributed in the housing or fixed thereto in a configuration corresponding to that of the implanted magnets, respecting the polarity of the latter.
  • According to a preferred variant of the invention shown in Figures 7 and 8 the outer casing 1 comprises a circular base 1a in which are housed one or two magnets 12a and 12b, and a lid 1b also of circular shape, in which are fixed the microphones 13a, 13b, and possibly the electronic circuits, and the source of energy. The base is held on the skull of the patient always in the same orientation according to one of the embodiments shown on the Figures 4 to 6 , depending on the respective polarities of the magnetic parts 21, 21a, 21b, while the lid 1b is pivotally mounted on the base 1a, and locked in an angular position relative to the latter by a fixing means, for example consisting of a central screw 25 passing through the lid and screwed into a central pivot provided in the base 1a. On the figure 7 it can be noted that the magnets are totally electrically isolated in the base, so as to avoid any electrical contact with the electronic circuits housed in the cover.
  • The figure 8 shows in broken lines three different positions of the cover relative to the base (the cable 4 rotates while the magnets 12a, 12b remain fixed).
    The microphone or microphones 13, 13a, 13b can thus be oriented in an optimal manner and with great precision by the practitioner responsible for setting the device or by the patient, following the implantation of the housing 2. Of this In this way, any implantation inaccuracies of the implanted housing 2 are dispensed with, resulting notably from differences in morphology from one patient to another.
    The patient can thus dispose and remove the housing 1 with great ease, always having the assurance that the microphones will be oriented correctly.
  • Of course, one can provide other ways of fixing the cover on the housing (grooves, notching, pads, etc.), without departing from the scope of the invention.
  • Alternatively or in combination, the microphone or microphones 13, 13a, 13b can also be arranged at the end of a respective rigid cable, connected to the outer casing 1. If the cable is conformable by the practitioner following the installation of the implanted housing 2, to arrange and correctly orient the microphones or microphones relative to the patient's head, it is not necessary that the outer casing 1 has a portion 1 has steerable.
  • As shown on the figure 9 , the implanted housing 2 advantageously comprises, in addition to the magnetic parts 21a, 21b, a system for collecting evoked or spontaneous auditory potentials. This system comprises at least two extra-cochlear collection electrodes 35, 36 connected to the housing. This system also comprises an electronic collection module 32 for amplifying and possibly processing the signals from the electrodes, 35, 36, a transfer module 33 including a transmitting antenna for transmitting to the outside for example by electromagnetic waves , via an amplitude or frequency modulation, the signals produced by the collection module 32, a power supply 31 comprising a battery and / or coils capturing the electromagnetic energy coming from an external coil, for example provided in the housing external 1. The housing 1 may also comprise a receiving module connected to a coil / antenna for receiving the signals emitted by the transfer module 33. In this case, the outer coil and the antenna of the receiving module can be fixed to the base 1a or cover 1b of the outer casing.
  • At least one of the collection electrodes 35, 36 is intended to be implanted near the inner ear of the patient, preferably on the round window. In this case, the collection module is designed to amplify and treat evoked or spontaneous acoustic potentials.
  • Alternatively, the collection electrodes 35, 36 are implanted under the skin of the patient, also in the temporo-occipital region of the skull, to measure evoked potentials and the collection module 32 is designed to amplify and possibly treat such potentials. For this purpose, the electrodes are for example arranged at the end of flexible tabs 34a, 34b attached to the housing 2. In this case, there is also provided a reference electrode R disposed on the housing 2 and connected to the collection module 32.
  • As shown on the figure 10 , the housing 2 encloses, alternately or in combination with the collection module 32, a stimulation module 37 connected to at least one active stimulation electrode 38, 39, implanted near the patient's inner ear, for example on the oval window or the round window of the middle ear, or in the cochlea. In the case of monopolar stimulation, the stimulation module 37 is connected to at least one neutral stimulation electrode remote from the inner ear. The pacing module is adapted to generate pacing signals from signals received from the outer casing 1 via the transfer module 33.
  • The electrodes 38, 39 may be replaced or combined with an electromechanical transducer vibrator, for example of the piezoelectric type, implanted in a bone or cartilaginous zone, preferably close to the patient's inner ear, to effect electromechanical stimulation.
  • In the embodiment where the implanted housing 2 comprises, in combination, the collection and stimulation devices, as described with reference to the Figures 9 and 10 , the collection and stimulation electrodes are, according to an advantageous variant, common and can operate alternately in collection mode and stimulation mode. In this case, according to a preferred embodiment of the invention, one of the electrodes 38, 39 is positioned on the round window and is both an active stimulation electrode, and alternatively, one of the potential acquisition electrodes. hearing.
