Definitions

  • the invention relates to a holding screen for a standard earpiece insertable in an insertion direction in an ear canal. Furthermore, the invention relates to a standard ear piece with a corresponding holding screen.
  • BTE hearing aids (behind-the-ear, or behind-the-ear or BTE) wear a housing with components such as a battery and the signal processing unit behind the ear.
  • a flexible sound tube also referred to as a tube, directs the receiver's acoustic output signals from the housing to the ear canal.
  • RIC (Receiver-In-Canal) hearing aids are BTE hearing aids with an electrical connection to a speaker worn in the ear.
  • ITE hearing aids in-the-ear, also IdO or in-the-ear
  • CIC hearing aids are similar to ITE hearing aids, but are worn fully in the ear canal.
  • the DE 202015000840 U1 discloses a hearing aid earmold for an ear canal for positioning a RIC hearing system with an earmold hollow body, integrated into the insulating plastic storage pocket, at the end of a bottleneck (clamp) for connecting ex-earphones different RIC hearing aids is introduced and one behind the bottleneck Universal mount for manufacturer-specific click sleeves.
  • the hearing aid ear mold allows a manufacturer-independent, so universal connection option of RIC hearing aid.
  • a dome which can be reversibly, ie detachably, connected to a receiver or hearing tube of a hearing aid.
  • the dome has a cerumen protection, which can be cleaned easily and without detaching the dome from the receiver or the receiver tube.
  • the cerumen protection according to DE 10 2014 200 605 A1 is softer compared to the inner part, wherein the inner part is adapted to produce a positive connection with a correspondingly shaped adapter reversible.
  • the cerumen protector comprises at least one elongated protective element, wherein a surface projection of each protective element extends radially perpendicular to the base surface of the cerumen protector with respect to the centroid of the surface of the cerumen protector.
  • the US 2015 049 897 A1 discloses an earpiece having a flange having an upper end and a lower end, the flange having a tear-shaped curved cross-section extending from the upper end to the lower end. Furthermore, the flange comprises an inner body through which an acoustic channel or sound channel extends. The flange closes in the inserted state of the ear piece at least partially an ear canal for ambient noise and forms at least a partial seal against air in the ear canal.
  • the sound channel here allows the passage of sound into the ear canal when the inner body is connected to a sound source.
  • instant-fit hearing systems can be used.
  • Such instant-fit hearing systems are designed to be as universally applicable as possible and include standard ear pieces which are small enough to be placed independently of the respective anatomy in the ear canal of the respective hearing aid wearer.
  • standard earpieces often do not have sufficient support in the auditory canal, since they are not adapted to the individual ear canal or auditory canal of the hearing device wearer. The ear pieces slip easily.
  • the standard ear piece is too large, the acoustic perception is often impaired, since the necessary for a pressure equalization in the ear ventilation can not always be ensured. By a correspondingly low ventilation unpleasant feedback effects are favored (occlusion effect).
  • standard hearing aids often give the hearing aid user an uncomfortable feeling due to the hard housing material.
  • the invention is a first object to provide a way that allows optimal hearing and a comfortable fit of the respective hearing aid when using a standard earpiece.
  • a second object of the invention is to provide a corresponding standard ear piece with improved wearing properties and improved hearing comfort.
  • the first object of the invention is achieved according to the invention by a holding screen for a standard ear piece which can be inserted into an ear canal in an insertion direction, comprising an end-side head piece and an adjoining wing portion, which is designed in such a way that the standard earpiece therein is at least 50 % of its length is receivable with the wing portion circumferentially spaced from the standard earpiece.
  • the invention is based on the fact that standardized ear pieces, such as in particular CIC hearing aids, RIC hearing aids or ear pieces of a BTE hearing aid with attached elastic holding screens, so-called Domes, can be used.
  • Domes standardized ear pieces, such as in particular CIC hearing aids, RIC hearing aids or ear pieces of a BTE hearing aid with attached elastic holding screens, so-called Domes.
  • a sufficient hold in the auditory canal or in the ear canal of the respective hearing device wearer can usually be achieved.
  • this does not improve the acoustic perception. Desired, however, are both optimal wearing comfort and optimum hearing.
  • the invention now meets these requirements by a holding screen, which adapts to the ear canal and at the same time ensures adequate ventilation.
  • the holding screen is for this purpose formed with an end-side head piece and an adjoining wing portion.
  • the standard ear piece is receivable in the support screen, in particular in the wing portion of the support screen, at least 50% of its length, and the wing portion is circumferentially spaced from the standard earpiece.
  • the holding screen is designed in particular so long that it covers the entire length between the isthmus, the constriction in the ear trumpet and the input into the ear canal in the state inserted into the standard earpiece and inserted into the ear canal. In this way the firm hold of the ear piece is ensured within the ear canal. Furthermore, the circumferential spacing between the standard ear piece and the holding screen or its wing section prevents the standard ear piece from abutting against or abutting the wall of the ear canal and thus giving the hearing aid wearer an uncomfortable feeling.
  • the holding screen comprises a number of ventilation openings, which penetrate the head piece substantially parallel to the insertion direction and open into the interior of the wing section.
  • the interior is given in the inserted state of the ear piece by the distance between the inner wall of the holding screen and the outer wall of the standard ear piece. Since the interior of the wing section on the outwardly facing side of the holding screen - ie at the entrance of the ear canal - is open, the interior represents a ventilation volume, which allows the necessary ventilation and thus the pressure equalization via the or each opening. An undesirable occlusion effect or closure effect is avoided.
  • the cross section of the holding screen widens in the insertion direction.
  • the in the inserted state of the holding screen (together with the standard ear piece) the isthmus facing head of the holding screen thus has a smaller cross-section than the located at the entrance of the ear canal wing section.
  • the centers of gravity of the cross-sectional areas of the holding screen along the insertion direction on a curved path is thus formed in the insertion direction with a curvature.
  • the geometry of the holding screen, so both the expansion of the holding screen and its curvature thus follows the contour of the ear canal and allows a secure and comfortable positioning of the ear piece. Nevertheless, the ear piece can thus be used for both a left ear and a right ear.
  • the holding screen or a standard ear piece with a corresponding holding screen is preferably reproducibly positionable within the ear canal.
  • the holding screen is preferably formed of two parts of different elasticity and thus also different flexibility.
  • the head piece has a lower elasticity than the wing portion.
  • the material of the head piece has a lower elasticity than the material of the wing section.
  • the retaining screen is preferably made of a plastic.
  • the head piece and the wing section In order to produce a holding screen with sections of different elasticities, it is particularly advantageous to produce the head piece and the wing section from the same material but with mutually different wall thicknesses.
  • the wing section in this case preferably has a smaller wall thickness than the head piece.
  • a further preferred possibility is to produce the head piece and the wing portion of the holding screen with different Shore hardness when using the same material. In such a retaining screen, the wing portion expediently has a lower Shore hardness than the head piece.
  • the headpiece is on the one hand flexible or elastic enough to ensure the desired comfort for the hearing aid wearer.
  • the head piece is sufficiently strong to give the hearing aid wearer a haptic feedback when inserting the earpiece into the ear canal, whether he has reached the intended end position - the isthmus. If this is the case, a further pushing of the standard ear piece with the attached holding screen from this point is difficult. The hearing aid wearer can therefore assume that the earpiece is located in the intended position within the ear canal.
  • the flexible, more elastic portion of the holding screen, so the wing section, along the wall of the ear canal ensures the desired comfort.
  • the length of the head piece in the insertion direction is less than half the length of the wing portion.
  • the holding screen is expediently fastened to the standard ear piece via the head piece or attached thereto in the plugged-on state.
  • the head piece preferably comprises a fastening opening for a frictional connection with the standard ear piece.
  • the attachment opening is preferably formed on the insertion-side end face of the holding screen. In the mounting hole, a fastener of the standard ear piece can be inserted to releasably fix both components together.
  • the second object of the invention is achieved by a standard ear piece with a holding screen according to one of the above-described embodiments.
  • the non-positive connection is designed as a rotatable clip connection.
  • the holding screen is attached to the standard ear piece.
  • the fastening element is preferably rotatably received in the attachment opening. Due to this rotatable embodiment of the clip connection, the standard earpiece together with the holding screen is suitable both for use in the ear canal of the right ear and in the ear canal of the left ear.
  • any earpiece which is located in the inserted state within the auditory canal of the hearing device wearer can generally be used as the standard earpiece.
  • the standard ear piece is designed as a standard CIC hearing aid (Completely-In-Channel).
  • the housing of the hearing aid ends in the outer part of the ear canal and is characterized by little or no visible from the outside.
  • the holding screen is attached to the hearing aid as described above and meets the requirements for comfort, secure fit and ventilation of the ear alike.
  • Fig. 1 shows a holding screen 1, which is a set as an instant-fit CIC hearing aid (shown schematically) standard earpiece 3 is placed.
  • the instant fit CIC hearing aid 3 with the holding screen 1 is inserted within an ear canal 5.
  • both components are inserted together in the insertion direction 7 in the ear canal 5.
  • the holding screen 1 covers the entire length between the isthmus 9, that is to say the constriction in the ear trumpet 11, and the input 13 into the ear canal 5.
  • the holding screen 1 comprises an end-side head piece 15 and a wing portion 17 adjoining the head piece 15, wherein the length of the head piece 15 in the insertion direction 7 is less than half the length of the wing portion 17.
  • the head piece 15 has a lower elasticity than the wing portion 17. If the instant-fit CIC hearing aid 3 is inserted into the ear canal 5, upon reaching the end position, ie when the isthmus 9 is reached, further insertion of the instant fit is possible. CIC hearing aid 3 difficult. The hearing aid wearer then knows that the instant fit CIC hearing aid 3 is positioned far enough in the ear canal 5.
  • the flexible wing portion 17 ensures that the holding screen 1 of the anatomy of the ear canal 5 adapts, so that the desired comfort for the hearing aid wearer is achieved.
  • the holding screen 1 is attached to the instant-fit CIC hearing aid 3 via a non-positive rotatable clip connection 19.
  • a fastening opening 21 is formed on the insertion-side end face 20 of the head piece 15, into which a fastening element 23, such as a ball head, of the standard ear piece 3 engages.
  • the standard earpiece 3, so the instant-fit CIC hearing aid is included within the holding screen 1 with presently 75% of its length L.
  • the wing portion 17 is in this case circumferentially spaced from the standard earpiece 3. The circumferential spacing between the instant-fit CIC hearing aid 3 and the holding screen 1 or its wing section 17 prevents the instant-fit CIC hearing device 3 from abutting against the wall of the ear canal 5 and thus preventing the wearer from suffering Hearing aid wearer exerts unpleasant pressure.
  • the holding screen 1 comprises a plurality of ventilation openings 25, which penetrate the head piece 15 substantially parallel to the insertion direction 7 and open into the interior 27 of the wing section 17.
  • the interior 27 is defined here by an annular space with the distance A between the inner wall of the holding screen 1 and the outer wall of the instant-fit CIC hearing device 3.
  • the ventilation openings 25 are formed as well as the attachment opening 21 on the insertion-side end face 20 of the head piece 15. In combination with the space 27 resulting from the circumferential spacing between the standard ear piece 3 and the wing section 17 of the holding screen 1, ventilation of the ear can take place through the interior space 27 of the holding screen 1. Vents in the instant fit CIC hearing aid 3 are not necessary.
  • the cross-section 29 of the holding screen 1 expands counter to the insertion direction 7, the cross-sectional areas 30 are thus opposite the direction of insertion 7 larger.
  • This is particularly apparent from the representation of the holding screen 1 according to Fig. 2 seen. It can be seen here the curvature of the holding screen 1, which are shown by way of example for some unmarked cross-sectional areas.
  • the centroids 31 of the cross-sectional areas are not on a straight line. Due to the curvature, the shape of the holding screen 1 is adapted both to the shape of the ear canal and to the shape of the instant fit CIC hearing aid 3.
  • the curvature reflects the anatomy of the ear canal 5 again.
  • the Instant Fit CIC Hearing Aid 3 is in sole representation Fig. 3 refer to.
  • the illustration also shows its curved shape.
  • the front-side fastener 23 can be seen, which serves to attach the holding screen 1.
  • the fastening element 23 engages in the fastening opening 21 formed on the insertion-side end face 20 of the head piece 15. In this way, the non-positive and rotatable clip connection 19 between the instant-fit CIC hearing aid 3 and the holding screen 1 comes about.
  • the attachment opening 21 of the holding screen 1 is in the Fig. 4 and 5 to see clearly again.
  • Fig. 4 is one of the ventilation openings 25, which penetrate the head piece 15 substantially parallel to the insertion direction 7 and open into the interior 27 of the wing portion 17 can be seen. Also, based on the illustration according to Fig. 4 to recognize that the length of the less elastic and correspondingly less flexible head piece 15 in the insertion direction 7 is less than half the length of the wing portion 17.
  • Fig. 5 shows a sectional view of a portion 35 of the holding screen 1. This illustration, the ventilation openings 25 as well as the attachment opening 21 on the insertion-side end face 20 of the head piece 15 can be seen.
