Definitions

  • Transmission device for introducing light into the ear
  • All of these devices have the basic structure in common that a light source is available for providing the radiation and for coupling the radiation into the ear area, a suitable holding device on the ear and a radiation guide, in particular an optical waveguide, for guiding the radiation in the frequency range used suitable is.
  • the treatment time for such applications is 15-60 minutes when using low-energy lasers; it must therefore be ensured that a minimum of comfort is guaranteed by the design of the holding device.
  • the power density of the radiation used and the place of exposure which ensures exposure to the cochlea are of medical importance; Both parameters essentially determine the therapeutic effectiveness of the radiation, but are also critical in order to avoid damage to health due to excessive and / or incorrectly positioned exposure to radiation.
  • the positioning device is to be inserted into the patient's auditory canal so that radiation via the external auditory canal and the eardrum acts on predetermined areas of the middle ear and / or inner ear.
  • the determination of these ranges as a function of the frequency range of the interfering tone or sound is medically controversial and complex.
  • DE 199 47 678 uses a low-level laser as the radiation source with a security element between the radiation source and the optical waveguide to prevent laser emissions without a connected optical waveguide. Nothing is said about the design of the holding device.
  • the object of the invention is to provide a device with which the transmission of light to the patient's ear is achieved in a reliable, easy-to-use and individually adaptable manner.
  • the basic idea of the invention consists in the two-part construction of an ear holder with a first transition piece, which is designed in such a way that it emits the radiation used, taking into account the orientation of the light guide in the direction of the ear canal, and with a holding bracket that can be attached to the first transition piece and that enables the individual fine adjustment and positioning of the transition piece.
  • a second transition piece is used to couple the radiation into the optical waveguide, which in turn consists of two parts, namely a first part for connection to the radiation source, in particular a laser, and a second part, a press tip which is connected to the input-side end of the optical fiber is firmly connected and can be used in the first part.
  • FIG. 1 an overall perspective view of the transmission device
  • Figure 2 a top view of the ear holder with the first transition piece
  • FIG. 3 a schematic sectional illustration of the transmission device according to FIG. 1,
  • Figure 4 a detail section through the structure of the second transition piece
  • FIG. 5 shows a schematic illustration for assembling an irradiation device with the transmission device according to the invention. Description of the preferred embodiment
  • the radiation from a low-energy laser (low-level laser) is used as the optical radiation;
  • a different radiation source with a different frequency or frequency spectrum.
  • the transmission device consists essentially of three parts: an optical waveguide 20, an ear holder 10, in which the ear-side end of the optical waveguide 20 is received, and a transition piece 30, in which the laser-side end of the optical waveguide 20 is received, for connection to a suitable low - Level laser 40.
  • the ear holder 10 consists of a first transition piece 11, which is preferably knee-shaped, in order to deflect the light guide 20, which generally runs in a vertical plane, into the essentially horizontal ear canal into which the laser radiation is to be introduced.
  • the optical waveguide 20 is thin (maximum 1000 ⁇ m) and thus so flexible that it can be inserted or inserted into the transition piece 11 with a bending radius of 2-5 cm. This enables a very compact construction of the transition piece 11, which in turn reduces the lever arm formed, so that the torque caused by part of the dead weight of the optical waveguide 20 is kept to a minimum around the point of contact of the transition piece 11 on the ear.
  • the transition piece 11 consists of two trough-shaped half-shells, one of which (11.1) is shown in cross section from above in FIG.
  • this half-shell several transverse webs 11.2 run into which the optical waveguide 20 is inserted.
  • the other half-shell is put on and welded by means of ultrasound, the wedge-shaped webs 11.3 press into the jacket of the optical waveguide 20 and lock it.
  • the end section 1 1A pointing towards the ear of the first transition piece 11 is enclosed by an exchangeable ear piece 13, for example made of soft plastic, which makes contact with the ear and is replaceable for hygienic reasons. Different sizes of the earpiece 13 are used to adapt to children's and adult ears.
  • a through hole 11 B is made in the latter (axis X-X), in which the first end region 12A of a holding bracket 12 is rotatably inserted.
  • the holding bracket 12 has an essentially U-shaped shape, its second end section 12B being elastically deformable, in particular bendable, so that it can be individually adapted to the shape of the ear cup, so that together with the ear piece 13, the ear holder 10 is securely fixed is guaranteed on the patient's ear.
  • the ear holder 10 shown can be used for both ears by simply moving the bracket 12.
  • the end section 11A is positioned in such a way that the unfocused, approximately conical radiation penetrates into the ear canal and strikes the eardrum with a power of approximately 3-4 mW.
  • the simple design of the holding device 10 described has proven to be an optimal compromise between technical effort and medical effect.
  • Avoiding focusing upon exiting end portion 11A ensures that cell damage that could occur if high power density focus areas were to be located on points of the ear canal or eardrum is avoided.
  • a second transition piece 30 is provided as a focus socket, the inner surface of which tapers conically towards the inlet opening of the optical waveguide 20 and is dimensionally It is niert that the focus area F of the laser light is immediately in front of the entrance opening of the optical waveguide 20.
  • the inner surface is coated to increase reflection, for example with chrome, gold or nickel.
  • the second transition piece 30 is provided in its end region on the light guide side with a cylindrical bushing, into which a press tip 32 is inserted, which receives the end region of the light waveguide 20 on the laser side.
  • the press tip 32 has a.
  • Through hole 33 with a first section 33A with a first radius R1, in which the end region of the coated optical waveguide 20 is glued, and a subsequent second section 33B (approx. 5 mm long) with a second radius R2, into which a stripped end section 20A of the optical fiber 20 protrudes over its entire length.
  • This press tip 32 is inserted into the socket of the transition piece 30, for example pressed in, so that the entry cross section of the optical waveguide end 20A is immediately behind the focus area F of the laser radiation and thus a largely loss-free coupling of the laser light into the optical waveguide 20 is ensured.
  • the second transition piece 30 and the laser 40 are connected to one another by means of a coupling section 42, for example in the manner of a bayonet lock, as is indicated in FIG. 5, or by simple screwing.
  • the laser has a tapered holding section 41, onto which a ring 39 is pushed, which has brackets 34, 35 on both sides for hanging a holding element 50, for example by means of eyelet elements 54, 55, so that the laser 40 can be carried by the patient to further reduce the torque acting on the transition piece 11.
  • This construction ensures very easy handling, combined with a secure and individually adjustable fit of the ear holder and thus reliable radiation onto the desired areas of the inner ear.
