Definitions

  • the invention relates to a supply unit according to claim 1.
  • Advantageous developments of the invention are the subject of the dependent claims.
  • a supply unit which comprises a profile-like housing mounted as a supply bar on the wall for wall or ceiling mounting above a patient bed.
  • the housing contains connections for power, medical gases, telephone, radio, data connection and the like.
  • supply units are usually equipped with a luminaire arrangement integrated in the housing.
  • a generic supply unit is from the DE202005016891U1 known.
  • a wall-mounted medical supply unit in which the luminaire arrangement is displaceable as a unit in the longitudinal direction. This allows the adaptation of the lighting to the installation of the patient bed.
  • the luminaire arrangement according to EP0739618 includes a down-shining luminaire grid, an upward luminaire for indirect room lighting and a smaller spotlight as a night or reading light for the patient.
  • a suspended ceiling-mounted supply unit is known, which also has an arrangement with a reading light and a ceiling lighting for indirect room lighting.
  • a known from the prior art solution is to attach to the supply unit or at the patient bed an additional examination light. This is usually fixed by means of an articulated support arm in order to be specially positioned for illuminating the area to be medically examined. Such surface-mounted lights are expensive, are perceived as disturbing obstacles and are maintenance-prone due to the positioning mechanism. In addition, such attached examination lights usually have to be time-consuming again for medical personnel to re-position.
  • the Solution according to the invention characterized in that at least one first and one second optics are arranged in the housing of the supply unit and specify different directional characteristics directed respectively for direct illumination on the spatial area belonging to the patient bed.
  • the directional characteristics of the optics cover different partial areas of an examination area, which essentially corresponds to the area in which the patient bed is set up.
  • the illumination is directed by the first optics and the second optics such that the two optics can be used in conjunction with one or more corresponding bulbs respectively as a medical examination light.
  • the lighting can be done together for the subsections in total.
  • the lighting means are each individually switchable for each sub-area, so as not to disturb the patient by illuminating too brightly and to save energy.
  • the optics thus allow the light of corresponding bulbs to be used specifically for medical examination and to achieve a suitable, substantially homogeneous illumination of the entire examination area in which the body of a patient can typically be located.
  • the proposed embodiment of the luminaire arrangement can be achieved in a simple manner suitable for medical examination lighting without a complex, disturbing and each newly repositioned holding arm would be required. On a respective repositioning of the examination lamp and / or a conversion of the patient bed can be completely dispensed with proper installation of the patient bed.
  • the substantially homogeneous illumination of the entire examination area is based on just one further reading light in addition to the already desired one achieved in the housing integrated lamp achieved.
  • the additional lamp illuminates a partial area of the examination area or patient bed which is complementary to the partial area illuminated by the reading light.
  • the complementary subregions, ie the complementary subregions taken together essentially cover the entire examination region, ie the complementary subregions complement one another to form the entire examination region.
  • the first optic is used together with a first illuminant as the examination light specifically and selectively for the head and / or foot area of the examination area and the second optic is used together with a second illuminant on the one hand as a reading light and on the other hand as an examination light for the trunk area.
  • the first optics is part of an examination light for the lower part of the trunk area and / or the foot area
  • the second optics with a second light source on the one hand as a reading light and on the other hand as a complementary examination light for the upper part of the trunk area and / or the head area be used.
  • the directional characteristic of the second optics which constitutes a part of the reading light, has a main beam axis which is different, for example steeper or less steep in a vertical plane, than the main beam axis of the directional characteristic which predefines the first optics.
  • the luminaire arrangement may consist of a plurality of essentially identically constructed functional groups, which differ only with regard to the preset direction of the light control.
  • each optic each comprises a lens arrangement which is arranged with a suitable angle of attack in the transverse plane to the housing.
  • the angle of attack is fixed to prevent the directional characteristic can be unintentionally adjusted by the staff.
  • one or more of the lens arrangements may comprise deflecting lenses or deflecting prisms which deflect the light of the associated illuminant in the desired manner.
  • a plurality of LEDs are preferably used.
  • the use of LEDs is energy-efficient and particularly space-saving. LEDs also make it possible to generate the most homogenous examination lighting without additional aids.
  • a preferred embodiment of the supply unit as a light source in each case for each optic comprises a row of LEDs, which are mounted side by side in the longitudinal direction of the housing of the supply unit.
  • the various optics can be arranged in the housing either as a continuous element or as a row of individual optical elements in such a way that they extend in the longitudinal direction corresponding to the LED rows. Individually juxtaposed optical elements may each be provided for a single or group of LEDs.
  • the optics can be integrated, for example, in the front and / or lower, the patient bed facing housing wall.
  • the lighting in the middle section can be used particularly ergonomically for reading.
  • the supply unit as a lighting means arranged one above the other three rows of LEDs.
  • the middle row of LEDs opposite the upper and / or the lower row can be mounted offset in the longitudinal direction.
  • the LEDs are fed group-wise switchable in such a way that each row can be switched on or off separately.
  • the examination illumination can be fully switched on, part of the examination illumination can be used as an energy-efficient reading light, and each area can be individually and specifically illuminated for examination.
  • each optic in each case has an arrangement with at least one collimator lens or with at least one reflector.
  • the light can be suitably bundled, and unwanted scattered light is avoided.
  • An elongate reflector or collimator can also be assigned to a plurality of LEDs in each case.
  • the desired directional characteristics can be specified specifically and precisely, irrespective of the precise and typically tolerance-related installation position of the LED.
  • a deflection lens is preferably placed on the radiation side of the collimator lens or arranged in front of the reflector.
  • a first, a second and a third optics are arranged in the housing of the supply unit.
  • the optics are expediently designed such that the directional characteristic of the first optic essentially covers the leg and foot region of a patient, the directional characteristic of the second optic essentially covers the region of the trunk or of the breast and possibly the pelvis and those of the third optic essentially captures the head area.
  • Certain overlaps of the illuminated areas may be present, but the directional characteristics should subdivide the entire examination area into as complementary partial areas as possible and achieve the most homogeneous possible illumination of the entire examination area.
  • suitable directional characteristics can be achieved in a particularly simple manner by the angles of the main beam axes of each directional characteristic with respect to a vertical plane of the inequality ⁇ > ⁇ > ⁇ meet.

  • the angle ⁇ the angle between the main beam axis of the second optics and the vertical

  • the rear side with the channel region 124 of the housing 122 is permanently attached to the wall 14.
  • the principal Construction of the MVE 120 can, with the exception of the luminaire arrangement proposed below, take place in a manner known per se. Suitable constructions of the housing 122 may, for example, analogous to the respective description EP1073172 or EP1096629 be removed.
  • a wall mounting according to FIG.1 is preferred, with the MVE 120 typically being mounted to the wall 14 at a mounting height H of the central axis L between 180-220 cm. Also not shown are the usual connection sockets or junction boxes of the MVE 120 for devices for medical care of the patient, for example cardiovascular monitoring devices, respirators, etc.
  • the MVE 120 has a luminaire arrangement with different emission or directional characteristics 22, 23, 24, which direct the light directly onto the patient bed 10.
