Definitions

  • the invention relates to a dome for an insertable into an ear canal hearing aid. Furthermore, the invention relates to a hearing aid with a corresponding dome.
  • a portable hearing device As a hearing aid device, a portable hearing device is generally referred to, which serves to improve the perception of the sounding of the user's ear ambient sound.
  • a classically referred to as "hearing aids" subclass of hearing aids is designed to care for people who suffer from medical loss of hearing.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE), hearing aids with external listeners (RIC, Receiver in the Canal), in-the-ear hearing aids (IdO), or also Concha hearing aids or canal hearing aids (ITE, CIC) offered.
  • BTE behind-the-ear hearing aids
  • RIC hearing aids with external listeners
  • IdO in-the-ear hearing aids
  • ITE Concha hearing aids or canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. In these
  • the hearing aid In order to support the part of the hearing aid to be worn in the ear within the ear canal, on the one hand a secure hold and on the other hand a sufficiently high wearing comfort is ensured for a durable wear, the hearing aid is usually provided with a dome, the one on flexible has the auditory canal customizable screen.
  • domes are made of silicone and, in order to ensure the passage of sound through dome, are provided with at least one sound passage opening.
  • the sound passage opening can be provided with a sound-permeable membrane.
  • this cerumen protective membrane can also be contaminated or added to cerumen itself. The then necessary cleaning of the dome or the replacement of Cerumenschutzes or the membrane is often expensive and especially for the end customer alone not feasible.
  • the use of bridge elements in the sound openings does not provide complete protection against contamination.
  • the invention is therefore based on the object of specifying a way to improve the protection of a hearing aid against unwanted contamination while simplifying cleaning.
  • the dome according to the invention for a hearing aid that can be inserted into an ear canal comprises an inner part and a screen made in one piece with the inner part with at least one opening.
  • a Cerumenschutz is arranged with at least one protective element which is flexibly umstülpbar in and against the insertion of the dome in an ear canal.
  • a cleaning element which is movable against the direction of insertion of the dome and is connected in a material-bonded manner to the screen.
  • a dome with a correspondingly designed cleaning element By using a dome with a correspondingly designed cleaning element, a low-cost cleaning for the wearer of the respective hearing aid is possible. Additional cleaning tools or the replacement of components of the dome can be omitted.
  • the cleaning element can thus be moved advantageously for cleaning in the space provided for this purpose and after cleaning in the starting position. Due to the cohesive connection of the cleaning element with the shield of the dome, the positioning of the individual components of the dome is fixed to one another. Slippage of the individual components is not to be feared.
  • the cleaning element is integrally connected to the at least one protective element. More preferably, the cerumen protection is materially connected to the shield of the dome. The cleaning element is thus connected to the screen via the at least one protective element of the cerumen guard.
  • the entire dome with the screen, the inner part, the Cerumenschutz (including the or each protective element) and the cleaning element is made in one piece.
  • the dome is suitably made of a flexible material, such as a thermoplastic elastomer or silicone.
  • the at least one protective element is arched in the insertion direction of the dome. Due to the curved design, the mobility of the protective element in and against the insertion of the dome is ensured and thus allows the movement of the cohesively connected to the protective element cleaning element also in and against the insertion of the dome.
  • the cleaning element preferably comprises an actuating element.
  • the actuating element is designed in particular rod-shaped.
  • the actuating element extends in the insertion direction through the at least one opening formed in the screen. In this way, the actuating element from the outside of the screen for a hearing aid wearer is accessible and thus allows this the use of the cleaning element or the execution of a cleaning process without additional cleaning tools.
  • the at least one protective element is preferably materially connected to the actuating element of the cleaning element and thus movable via the actuating element in and counter to the insertion direction of the mandrel.
  • the at least one protective element expediently comprises a foot which extends in the radial direction in the opening of the screen relative to the insertion direction and which is connected in a material-locking manner to the actuating element. A movement of the actuating element thus causes a movement of the at least one protective element.
  • the cleaning element based on the insertion direction, at least one in the radial direction outwardly extending wings.
  • This at least one wing is expediently also bonded cohesively to the actuating element of the cleaning element and preferably extends from the actuating element into the opening of the screen. If the actuating element is moved, for example, in the direction of insertion of the dome, the at least one protective element moves in this direction due to the cohesive connection between the wing and the actuating element.
  • the peripheral surface of the at least one vane of the cleaning element comes here - so when moving the actuator - advantageously on the inner surface of the opening of the screen to the plant. More preferably, the side surfaces of the at least one wing of the cleaning element come to rest on movement of the actuating element on the side surfaces of the protective element. In this way, impurities accumulated in the opening of the screen are pushed out of the opening by the wing of the cleaning element and can be removed.
  • the number of protective elements of the cerumen protection and the number of wings of the cleaning element are not limited.
  • the cerumen protection comprises as many protective elements as the cleaning element comprises wings.
  • the wax guard is formed with at least two spaced-apart protective elements and the cleaning element has at least two wings which engage in a movement of the actuating element in the spaces formed by the spacing of the protective elements from each other.
  • the peripheral surfaces of the wings are within the spaces expediently on the inner circumferential surface of the opening of the screen and the side surfaces of the wings come on movement of the actuating element on the side surfaces of their respective adjacent protective element to the plant.
  • the hearing aid according to the invention comprises a dome with the features of the above claims.
  • the use of such a one-piece dome with integrated cleaning tool eliminates additional cleaning tools. Even on a replacement of the cathedral or the cerumen protection can be dispensed with.
  • a hearing aid device is understood to mean, inter alia, headsets or headphones and in particular classical hearing aids.
  • the hearing aid itself expediently comprises at least one microphone, a signal processing unit with an amplifier and a receiver, as well as further electronic and functional components.
  • the dome of the hearing aid device according to the invention is expediently positioned on or on the part of the respective hearing aid worn in the ear canal.
  • Fig. 1 3 shows a dome 1 as part of a hearing aid 2 which can be inserted into an ear canal.
  • the dome 1 comprises an inner part 3 and a screen 5 which is made in one piece with the inner part 3.
  • the umbrella 5 has an opening 7 within which a cerumen protection 9 is arranged. Furthermore, the screen 5 has five openings 10 for open supply.
  • the wax guard 9 is made in one piece with the screen 5 of the dome 1.
  • the wax guard 9 comprises four protective element 11, which are flexibly umstülpbar in and against the insertion direction 13 of the dome 1 in an ear canal.
  • the protective elements 11 are curved in the insertion direction 13 of the dome 1 and spaced uniformly over the circumference of the wax guard 9. By the spacing of the protective elements 11 from each other between these spaces 15 are formed.
  • the dome 1 comprises a cleaning element 17 that can move in and against the insertion direction 13 of the dome 1.
  • the cleaning element 17 is connected in a materially bonded manner to the protective elements 11 of the cerumen guard 9 and thus also to the shield 5.
  • the cleaning element 17 or its cohesive connection with the protective elements 11 is in Fig. 2 to see.
  • the cohesive connection is realized via an actuating element 19 of the cleaning element 17.
  • the actuating element 19 is presently rod-shaped and extends in the insertion direction 13 through the aperture 7 formed in the screen 5.
  • the protective elements 11 each comprise a base 23 which extends in the radial direction 21 in the opening 7 of the screen 5, relative to the insertion direction 13, and which is connected to the actuating element 19 by material engagement. Both the cleaning element 17 itself and the four protective elements 11 of the cerumen guard 9 can be moved via the actuating element 19 in and counter to the insertion direction 13 of the dome 1.
  • the cleaning element 17 with respect to the insertion direction 13 of the dome 1 present four in the radial direction 25 outwardly extending wings 27.
  • Three of the four wings 27 are in the section of the dome 1 according to Fig. 2 to recognize.
  • the wings 27 of the cleaning element 17 are made in one piece with the actuating element 19 and also spaced uniformly arranged thereon.
  • the wings 27 of the cleaning element 17 engage in the spaces 17 formed by the spacing of the protective elements 11.
  • the cohesive connection of the protective elements 11 with the cleaning element 17 becomes clear.
  • the feet 23 of the protective elements 11 are each materially connected to the actuating element 19 of the cleaning element 17.
  • the cross-section of the dome according to FIG. 4 additionally shows that, when the wings 27 of the cleaning element 17 engage, they are formed in the area between the protective elements 11 Gaps 15 (upon actuation of the actuating element), the side surfaces 33 of the wings 27 on the side surfaces 35 of the respective adjacent protective elements 11 comes to rest.
  • FIGS. 5 and 6 each show the four protective elements 11 of the wax guard 9 together with the cleaning element 17. Based on the illustrations, the cohesive connection of the feet 23 of the respective protective elements 11 with the actuating element 19 of the cleaning element 19 can be clearly seen.
  • the entire dome 1 with the screen 5, the inner part 3, the wax guard 9 with the present four protective elements 11 and the cleaning element 17 is made in one piece from a thermoplastic elastomer.
