Definitions

  • the present invention relates to an earmold with connection device for connecting the earmold with hearing aids, external listeners of hearing aids, sound tubes with a diameter of less than 2.5 mm or ear protection elements.
  • Hearing aids are used to compensate for hearing loss, which can be worn behind (BTE) or in the ear (LDO as CIC or ITE).
  • BTE devices have the advantage that a relatively large amount of space is available for the electronics, so that a variety of technical options and high amplification performance can be realized.
  • the incoming sound is recorded, processed and forwarded either by means of a receiver located in the hearing aid via a sound tube or electrical signal via an electrical line to a remote outside the hearing aid external listener, both sound tube and handset with an individual after Made custom, located in the ear canal earmold are connected.
  • the earmold is usually made of hard material, with severe hearing damage, it closes the ear canal almost completely. In case of slight hearing damage, the ear canal is kept as open as possible by providing the earmold with a ventilation hole (Venting), which allows pressure equalization.
  • From the DE 201 14 121 is a trained as a socket-connector connection, two-piece quick coupling between a sound tube and a hard earmold known, which is attached to the end of the sound tube and the earmold.
  • Sleeve and plug have complementary locking connections.
  • the sleeve is arranged on a side facing the sound tube side of the earmold to these molded neck and has a groove into which engages a bead of the sound tube arranged on the plug.
  • This document also proposes a frictional mounting by conical design of sleeve and plug.
  • From the DE 20 2006 006 851 is a detachable connection between the sound tube and earmold known that produces a frictional connection of the two parts via conical configuration, wherein the compound is disposed on the side of the earmold, which faces the hearing aid.
  • a non-individualized ear piece in which the ear piece, a sound tube and a retaining spring are formed as a one-piece piece, or, at the sound tube and retaining spring are anchored by means of a connecting part in the earpiece.
  • the connecting device is arranged on the inside of the earmold on a support, wherein the carrier forms a distal end of the earmold from the hearing aid and wherein the carrier and the connecting device are integrally formed.
  • the connecting device is arranged in the interior of the otoplastic, the size of the otoplastic can be kept small with great advantage. In contrast to the prior art, the connecting device does not take up more space in the narrow and crooked ear canal than the otoplastic alone.
  • the otoplastic can thus also accommodate the relatively voluminous plug external listeners that would otherwise stick in the narrow ear canal, so that a connection would often prevented.
  • the hearing protection elements in particular in the form of filter elements with different filter characteristics.
  • the connecting device is arranged on a carrier, it is not possible with great advantage to use the connecting device itself, but the carrier for connection to the otoplastic. This reduces the design effort for the design of the connecting device.
  • the carrier forms a remote from the hearing of the end of the earmold, the sound coming from the sound tube or the external handset or the hearing protection element is emitted almost immediately before the eardrum, so that due to the small remaining auditory canal volume a strong sound pressure Achieved eardrum.
  • a stronger signal is passed on, or can be achieved with less hearing aid design the same signal strength.
  • the connecting device is designed as a sleeve and / or the carrier is designed as a flat plate.
  • a sleeve is straightforward in construction and corresponds to plugs of external listeners or locking elements of sound tubes and ear protection filters, so that a simple, functional connection is possible.
  • the plate can have any desired shape and thickness, for example round, angular or oval.
  • a flat, oval plate is preferred because it is easily adaptable to an earmold, easy to manufacture and store.
  • a plate also has the advantage that a larger connection surface to the earmold than in the prior art is available.
  • the plate is integrally formed with sleeve connected to the earmold is achieved with great advantage that the connection of earmold and sleeve is durable and easy to produce.
  • the cohesive connection prevents unwanted sound entering or exiting, at the same time the sleeve is held safer due to the larger contact surface between earmold and plate than in the prior art, where, for example, only a narrow neck is available.
  • it is also provided to form the earmold and plate with sleeve in one piece.
  • the sleeve is axially slotted, preferably formed axially slit three times at a distance of 120 ° each, and has a penetration depth restriction and / or at least one locking device, in particular in the form of a groove and / or bead, it will advantageously be an optimum adaptation to different connectors the different, according to the invention can be connected with the earmold devices such as sonic tubes, external earphones and ear protection elements allows.
  • the axial slots allow expansion of the sleeve during insertion of the plug in the context of the elasticity of the material used, so that damage to the sleeve can be avoided. Two, four or five slots can also be provided according to the invention.
  • the expansion further allows the use of a material of lower elasticity for the sleeve, since the lack of elasticity is compensated by the mechanical expansion.
  • the stiffer material which can be used according to the invention requires with great advantage greater forces in order to separate the plug-socket joint. This ensures that the earmold can be safely pulled out of the ear canal on the sound tube, an external receiver or an ear protection element. The opposing static friction forces of the ear canal are safely overcome.
  • the connecting device has a penetration depth restriction, in particular in the form of a conical bead in the bottom region of the sleeve directly above a sound outlet bore of the carrier, an excessively deep penetration of a plug is prevented, so that no widening of the sleeve beyond the elasticity of the sleeve material by the expansion in the Usually larger diameter handle portion of the plug can take place.
  • the sleeve on a locking device in particular in the form of a groove or a bead corresponding to corresponding grooves or beads of the plug.
  • the sleeve is designed for receiving sound tubes with an outer diameter of less than two and a half millimeters and / or the inclusion of ear protection elements and / or the inclusion of connectors external listener.
  • the use of optically advantageous thin sound tubes, which are hardly visible due to their small outer diameter, is made possible by the described embodiment of the sleeve according to the invention.
  • the sound tube and hearing protection filter elements can be added so that the earmold can be provided in the case of individual hearing protection with different ear protection filter elements.
  • the individual hearing protection can be easily adapted to different acoustic loading conditions by simply replacing the inserted filter elements. This advantageously avoids having to make different individual hearing protectors for one and the same person.
  • plug external handset can be included, so that with great advantage the sound directly in the otoplasty through a hole in the direction of the eardrum and the sound passes with high sound pressure to this.
  • This inventive embodiment is made possible by choosing appropriate sleeve inner diameter.
  • the connecting device consists of a photocurable or thermoplastic material. This has the advantage of producing sleeve and plate in large quantities by means of rapid prototyping or injection molding, and to be able to use the materials required for the respective application.
  • the method according to the invention achieves the object by the steps of creating an earmold for an ear canal.
  • Creating a carrier with connecting device, in particular a sleeve by means of rapid prototyping or an injection molding method, connecting the carrier and earmold so that the sleeve projects into the interior of the otoplastic, adapting the carrier geometry to the otoplastic and, if appropriate, introducing a ventilation bore into the carrier.
  • the method according to the invention for producing an earmold with connecting device comprises the steps of: creating a data record defining an individual otoplastic, inserting a data record defining a carrier with a connection device into the data record of the first step, creating a one-piece otoplastic with connecting device by means of rapid prototyping.
  • Both methods of the invention begin with the casting of an ear canal and the creation of a model. This can be either cast or as a dataset.
  • a prefabricated plate with sleeve is attached to the earmold after creating the earmold that the sleeve protrudes into the interior of the earmold. The attachment takes place cohesively.
  • a customizable according to size and location ventilation opening can be introduced.
