Description

(1) The present invention will be described in the following purely by way of example with reference to an advantageous embodiment and to the enclosed drawings. There are shown:

(2) FIG. 1 a perspective view of a patient support with two support parts coupled to one another;

(3) FIG. 2 the patient support of FIG. 1 without a coupled support part; and

(4) FIG. 3 a schematic view of an antenna.

(5) FIG. 1 shows a patient support for an operating table, treatment table or the like having two support parts 10 and 12 which can be coupled to one another, with the actual support surface of the support part 12 not being shown, but rather only one of two coupling hooks 14 being recognizable in FIG. 1. In this respect, the support part 10, which is stationary in the embodiment shown, that is it is not held pivotably, has a drive motor 16 which pivots a coupling disk 18 about a pivot axis S. Since the support part 12 is hung by the coupling hook 14 to the coupling disk 18, the support part 12 is pivoted relative to the support part 10 by rotating the coupling disk 18 by means of the motor 16. It must additionally be mentioned that the arrangement shown in FIG. 1 is also present on the oppositely disposed side of the support parts so that a total of two motors 16 are provided which in total drive two coupling disks 18, with the support part 12 being releasably connected to the coupling disks 18 via two coupling hooks 14.

(6) To transmit data and/or electrical energy between the two support parts 12, 14, a transmission device is provided which comprises a first coupling component and a second component which communication wirelessly with one another, with the components likewise being moved relative to one another about the pivot axis S on a pivoting of the support part 12 relative to the support part 10. In the embodiment shown, one component is an antenna and one component is an RFID chip 20. The RFID chip 20 is integrated into the coupling hook 14 and is therefore only shown dashed in FIG. 1. In the representation of FIG. 2, in contrast, the RFID chip 20 is shown in its position of FIG. 1; however, the support part 12 and the pivot hook 14 have been omitted in the representation.

(7) As FIG. 1 and FIG. 2 illustrate, a curved antenna 22 is provided as one component of the transmission device which extends along a circular segment concentric to the pivot axis S over an angular range of approximately 75. In this respect, the antenna 22, which has a thickness of some few millimeters in parallel with the pivot axis S, is arranged and fastened to the support part 10 about the pivot axis S such that the antenna 22 is swept over by the RFID chip 20 on a pivoting of the support part 12. Since the RFID chip 20 and the antenna 22 have substantially the same width relative to the pivot axis, viewed in the radial direction, and since the antenna 22 is concentric to the pivot axis S, the RFID chip 20 also always remains at the same radial position relative to the antenna 22 on a pivoting of the support part 12 relative to the support part 10.

(8) The antenna 22 comprises a plastic housing which is fastened to the support part 10 by two screws, with an antenna wire 24 being molded into the plastic housing in a configuration such as is shown in FIG. 3. As FIG. 3 shows, the antenna wire 24 is shaped to form a first winding which extends in curved form from the feed up to the end of the antenna and back again. A second winding is formed in that the antenna wire is again guided in the direction of the first winding before the feed and is subsequently led in the same manner above or beneath the first winding in the direction of the feed.

(9) The antenna 22 or the antenna wire 24 can then be connected to a control with whose aid the data contained in the RFID chip such as identification data, serial numbers, type designations, dimensions or the like can the read out so that the control obtains information on which support part 14 it is. It is also conceivable in this respect to integrate a rotary encoder into the antenna 22 so that the pivot position in which the support part 14 is actually located can simultaneously be read out.
