Definitions

  • the present disclosure relates to a tool for inserting and removing a hearing aid, to a hearing device and to a kit. More particularly, the disclosure relates to a tool for inserting and removing a deep-in-canal hearing aid into/from an external acoustic meatus ((external) ear canal) of a user and/or a canal of a storage device, to a hearing device comprising the tool and the hearing aid, and to a kit comprising the tool, the hearing aid and a storage device.
  • Hearing instruments inserted deeply in the ear canal in order to obtain invisibility are difficult to handle.
  • the device is only to be handled by a hearing care professional. If it is made possible for the end user (user) to fully control the insertion and removal of the hearing aid, new possibilities occur and a larger user segment is addressed.
  • the hearing instrument may, for instance, be removed when swimming or at night, when a battery charge or change is needed in case of rechargeable hearing aids or for cleaning the hearing aid. In short, in this case the handling would become more convenient for the user and the user would become less dependent on assistance by others.
  • Deep-in-canal hearing aids are often meant to obtain a so called bony-seal, where the hearing aid obtains a tight sealing to the ear canal wall in the innermost part of the external ear canal (the bony part of the ear canal) where the skin is very thin and the canal opening is surrounded by osseous tissue (bone tissue) instead of cartilaginous tissue.
  • the hearing aid shall not be inserted too deep into the ear canal, since the hearing aid could abut the tympanic membrane (eardrum), thus causing pain or an uncomfortable feeling to the user, or could even damage the eardrum. Hence, maintaining a safe distance of approximately 3mm from the eardrum is desirable.
  • the hearing aid shall not be inserted too shallow into the ear canal, since this placement of the hearing aid would result in an incorrect acoustic amplification and a risk of occlusion problems for the user.
  • the desired or proper insertion position differs amongst the users, since each ear canal is formed individually.
  • Another issue relates to inserting the hearing aid into a storage case (storage device), which is configured to charge the hearing aid battery.
  • a storage case storage device
  • a tool for inserting and removing a deep-in-canal hearing aid into/from a canal comprises a base, a coupling and a stop.
  • the coupling is fixed to one longitudinal end portion of the base and is configured to be coupled to the deep-in-canal hearing aid.
  • the stop is attached to the base, and is movable in the longitudinal direction of the base. The stop is configured to be fixed to the base.
  • the hearing aid can be inserted into the canal such that the hearing aid is reliably and safely placed at a desired or predetermined position in a longitudinal direction of each canal.
  • a hearing device comprises the tool according to any of the aspects presented herein, and the deep-in-canal hearing aid.
  • the hearing device is a system of at least the tool and the hearing aid.
  • a kit comprises the hearing device according to any of the aspects presented herein, and a storage device.
  • the storage device has the canal configured to accommodate the deep-in-canal hearing aid.
  • a tool according to any of the aspects presented herein is provided, wherein the stop is configured to abut the inner or the outer periphery of an opening of the canal.
  • a tool according to any of the aspects presented herein is provided, wherein the stop is fixable to the base by a screw, preferably by a setscrew.
  • the insertion depth can be adjusted to the dimension of the individual ear canal and can be prevented from being (unintentionally) changed again.
  • the adjusted insertion depth can be easily changed by loosening the screw.
  • the setscrew allows for keeping the dimensions of the tool small and for avoiding protruding parts of the tool coming into contact with the ear canal walls, thus injuring the ear canal or causing an uncomfortable feeling.
  • a tool according to any of the aspects presented herein is provided, wherein the stop is fixable to the base by shrinking.
  • a tool according to any of the aspects presented herein is provided, wherein the stop is fixable to the base by adhesive bonding.
  • a tool according to any of the aspects presented herein is provided, wherein the stop is disc-shaped.
  • a tool according to any of the aspects presented herein is provided, wherein the stop is configured to taper toward the coupling.
  • the stop will work despite the size variations of the ear canals. Further, since there is no abrupt abutment of the stop to the ear canal walls, which taper as well, and also due to the deformability of the skin in the bony part of the ear canal, there is a small degree of play in the longitudinal direction when the stop abuts the ear canal walls.
  • a tool according to any of the aspects presented herein is provided, wherein the base has an elongated tubular form.
  • a tool according to any of the aspects presented herein is provided, wherein the base has an elongated form and is flexible, and is thus configured to adapt to the contour of the canal.
  • a tool according to any of the aspects presented herein is provided, wherein the coupling is a magnetic coupling and/or a mechanical coupling.
  • the magnetic coupling allows for simply coupling the tool and the hearing aid without the necessity of bringing the coupling of the tool exactly in position relative to the corresponding coupling of the hearing aid. In other words, it is sufficient to bring the coupling of the tool only roughly in the vicinity of the coupling of the hearing aid so that the magnetic attractive force between the couplings ensures the proper connection. This allows for easily handling the tool, particularly for users having only limited psychomotor skills. Further, the magnetic coupling is less likely to mechanically damage other objects, e.g., when being worn in the same bag or pocket of the user.
  • the mechanical coupling allows for firmly coupling the tool without any interference. Further, the mechanical coupling provides a constant functionality over time.
  • a mechanical coupling does not impair other magnetic devices, such as magnetic strips of cards, e.g., when being worn in the same bag or pocket of the user.
  • the mechanical coupling is particularly suitable for rotating the hearing aid, particularly, if stops, such as protrusions and recesses, are additionally provided or simply by abutment of parts of the two couplings.
  • a tool according to any of the aspects presented herein is provided, wherein the coupling comprises a hook and an eye or a bayonet joint or a biased snap-fit element.
  • a tool according to any of the aspects presented herein is provided, wherein the tool comprises a handle.
  • the handle is fixed to the other longitudinal end portion of the base, and is configured to be held by a user.
  • the stop is attached to the base between the coupling and the handle in the longitudinal direction of the base.
  • kits according to any of the aspects presented herein is provided, wherein the kit comprises a charging unit.
  • the charging unit is configured to charge a battery of the deep-in-canal hearing aid, preferably by wireless charging.
  • the storage unit can be configured such that the power transmitting coil of the charging unit can be placed and be (removably) fixed in the storage device in accordance with the insertion depth obtained by the tool, and particularly by the stop, when inserting the hearing aid into the storage device. This allows for delivering the necessary electromagnetic field as efficiently as possible to the hearing aid reception coil or antenna making use of the well defined position and/or orientation of the hearing aid inside the storage device.
  • a hearing device includes a hearing aid and a tool for inserting the hearing aid into a canal and for removing the hearing aid from the canal.
  • a hearing device may include a hearing aid that is adapted to improve or augment the hearing capability of a user by receiving an acoustic signal from a user's surroundings, generating a corresponding audio signal, possibly modifying the audio signal and providing the possibly modified audio signal as an audible signal to at least one of the user's ears.
  • Such audible signals may be provided in the form of an acoustic signal radiated into the user's outer ear.
  • the hearing aid is adapted to be worn in any known way. This may include In-the-Canal (ITC)/ Completely-in-Canal (CIC) type hearing aids.
  • ITC In-the-Canal
  • CIC Completely-in-Canal
  • a hearing aid in general, includes i) an input unit such as a microphone for receiving an acoustic signal from a user's surroundings and providing a corresponding input audio signal, and/or ii) a receiving unit for electronically receiving an input audio signal.
  • the hearing aid further includes a signal processing unit for processing the input audio signal and an output unit for providing an audible signal to the user in dependence on the processed audio signal.
  • the input unit may include multiple input microphones, e.g. for providing direction-dependent audio signal processing.
  • Such directional microphone system is adapted to enhance a target acoustic source among a multitude of acoustic sources in the user's environment.
  • the directional system is adapted to detect (such as adaptively detect) from which direction a particular part of the microphone signal originates. This may be achieved by using conventionally known methods.
  • the signal processing unit may include an amplifier that is adapted to apply a frequency dependent gain to the input audio signal.
  • the signal processing unit may further be adapted to provide other relevant functionality such as compression, noise reduction, etc.
  • the output unit may include an output transducer such as a speaker/ loudspeaker/ receiver for providing an air-borne acoustic signal.
  • the disclosure relates to a mechanical tool for easy insertion and removal of a deeply inserted in-the-canal hearing aid and obtaining the correct position of the aid in the ear canal.
  • the miniaturized hearing aid shall be removable by means of a magnetic/mechanical system, where one or more magnets are used to guide the mechanical parts and the parts are locked together by means of a mechanical hook system.
  • the mechanical hook system works without any magnetic support.
  • the current disclosure deals with obtaining the correct insertion position/ depth in the individual ear canal.
  • Figure 1 illustrates a hearing device comprising a tool 10 and a hearing aid 20 according to an embodiment of the disclosure, wherein the tool 10 is used to insert the hearing aid 20 into an ear canal 30 of a user or is used to remove the hearing aid 20 from the ear canal 30 of the user.
  • Figure 1 shows the hearing device consisting of the tool 10 and the hearing aid 20.
  • the tool 10 comprises a base 11, a coupling 12, a handle 13 and a stop 14.
  • the coupling 12, the stop 14 and the handle 13 are provided at the base 11 in this order from the medial end to the lateral end of the tool 10.
  • the tool 10 (base 11) is of fixed overall length. In other words, the distance from the handle 13 to the coupling 12 is fixed.
  • the coupling 12 is provided at the medial tip end of the base 11, i.e., at one longitudinal end portion 11a of the base. This allows for a better coupling to the hearing aid 20.
  • the coupling 12 is permanently fixed to the base 11.
  • the stop 14 and the handle 13 are disc-shaped. This provides for a large cross-sectional area while keeping both elements simple and saving material costs.
  • the large cross-sectional area of the stop 14 provides for a save abutment.
  • the large cross-sectional area of the handle 13 provides for a batter grip.
  • the handle 13 is provided at the tip end of the lateral end of the base 11, i.e., at the other longitudinal end portion of the base 11. This allows for a better handling of the tool 10 and for utilizing the whole length of the base 11 for moving the stop 14 in the lateral and medial direction in order to adjust the insertion depth of the hearing aid 20.
  • the handle 13 is permanently fixed to the base 11.
  • the insertion depth of the hearing aid 20 is adjusted, preferably by a hearing care professional, before using the hearing aid 20 for the first time.
  • the hearing aid 20 is carefully inserted into the ear canal 30 until it reaches the predetermined position.
  • the stop 14 is movable along the base 11. Before inserting the hearing aid 20, the stop 14 can be moved far toward the medial side of the base 11, so that it quickly abuts the pinna and then slides on the base 11, when the base 11 is inserted further into the ear canal 30.
  • the stop 14 is directly fixed to the base 11, while the tool 10 and the hearing aid 20 are still inserted in the ear canal 30.
  • the tool 10 and the hearing aid 20 can be carefully removed from the ear canal 30, while temporarily fixing/ holding the stop 14 so that it does not slide along the base 11.
  • the stop 14 is then fixed to the base 11, while the tool 10 and the hearing aid 20 are removed from the ear canal 30.
  • the tool 10 includes the stop 14, which is adjusted in position according to the individual ear canal 30 dimensions. This adjustment is preferably done by the hearing care professional as part of the initial fitting, and as a result, the stop 14 is fixed in the correct position either by a screw, by glue, by heating or by other means.
  • the fixing can be done by any suitable means, such as by bonding using an adhesive, by screwing it to the base 11 or by shrinking.
  • the shrinking can be done by heating the stop 14 or by placing the stop 14 on a sleeve (not shown), which is inserted into the central hole of the stop 14 and around the base 11. After being heated, the stop 14 or the sleeve shrink and provide a force fit (frictional connection) with the base 11.
  • the user can safely insert the hearing aid 20 into the ear canal 30 without the risk of damaging the eardrum.
  • the coupling 12 is coupled to (connected to, engaged with) a (not shown) coupling of the hearing aid 20. Then, the hearing aid 20 is inserted until the stop 14 abuts the outer periphery of an opening 31 of the ear canal 30, i.e., abuts a part of the pinna. Alternatively (depending on the size of the disc-shaped stop 14 or if the stop 14 has a different shape, such as a conical shape), the stop 14 can abut the inner periphery of the opening 31 of the ear canal 30. Subsequently, the tool 10 is decoupled (disconnected, disengaged) from the coupling of the hearing aid 20 and is removed from the ear canal 30.
  • Figure 2A illustrates a tool 10 according to an embodiment of the disclosure.
  • the stop 14 is arranged more on the lateral side than on the medial side of the base 11. This adjustment of the stop 14 results from a relatively large length of the ear canal 20 of a user. In other words, with this arrangement, the hearing aid 20 can be inserted relatively deep into the ear canal 20.
  • Figure 2B illustrates a tool 10 according to an embodiment of the disclosure in which the stop 14 is arranged further toward the medial side of the tool 10 than in the tool 10 shown in Figure 2A .
  • the stop 14 is arranged approximately in the center of the base 11 in the longitudinal direction of the base 11. This adjustment of the stop 14 results from a smaller length of the ear canal 20 of a user than the length according to which the tool 10 of Figure 2A has been adjusted. In other words, with this arrangement, the hearing aid 20 cannot be inserted as deep into the ear canal 20 as with the tool 12 shown in Figure 2A .
  • Figure 2C illustrates a tool 10 according to an embodiment of the disclosure in which the stop 14 is arranged even further toward the medial side of the tool 10 than in the tool 10 shown in Figure 2B .
  • the stop 14 is arranged more on the medial side than on the lateral side of the base 11. This adjustment of the stop 14 results from a relatively short length of the ear canal 20 of a user. In other words, with this arrangement, the hearing aid 20 cannot be inserted as deep into the ear canal 20 as with the tool 12 shown in Figure 2B .
  • Figures 2A to 2C show the tool 10, where the stop 14 is shown in three different positions, Figure 2C representing the shortest ear canal 30 length.
  • the tool 10 can be used for inserting the hearing aid 20 into a storage device (not shown).
  • the storage device has a canal (opening), which corresponds to the ear canal 30 of the user.
  • the storage device and the canal thereof have one or only a few standard sizes.
  • the length of the storage device substantially corresponds to the length of the tool 10 (the base 11).
  • the width of the storage device substantially corresponds to the width of the tool 10 (the dimensions of the handle 13 or the stop 14) and the hearing aid 20.
  • the height of the storage device substantially corresponds to the height of the tool 10 (the dimensions of the handle 13 or the stop 14).
  • a charging unit is provided movably in the longitudinal direction of the storage device.
  • the dimensions of the storage device then increase accordingly.
  • the location of the storage device can be adjusted to the insertion depth of the tool 10.
  • the hearing aid 20 is inserted into the canal by means of the tool 10, until the stop 14 abuts (a part of) the storage device. If the storage device has a openable cover, the predetermined position in the storage device can be easily recognized. Then, the charging unit is moved in the vicinity of the predetermined position and is fixed within the storage device. Thus, the battery of the hearing aid can be recharged efficiently.
  • This structure of the storage device is particularly desirable in the case that the charging unit is a wireless charging unit.
  • a wired charging unit may also utilize this structure, e.g., if a delicate (sensitive) plug-and-socket-connection is used to which only small forces should be applied.
  • the stop 14 provides for limiting the compressive force on the connection during insertion, thus protecting the connection from being damaged.
  • connection or “coupled” as used herein may include wirelessly connected or coupled.
  • the term “and/or” includes any and all combinations of one or more of the associated listed items. The steps of any disclosed method are not limited to the exact order stated herein, unless expressly stated otherwise.
