  • Height-adjustable supply unit for receiving working devices, especially medical devices
    Patent number: 5113897
    Abstract: A medical supply unit with a height-adjustable connection head, e.g., in the form of a ceiling-mounted supply unit or ceiling lamp, is able to receive a working device, e.g., an anesthesiological apparatus, while ensuring reliable coupling for this purpose, so that the user will be able to perform a procedure reliably, with the working device being correctly connected. This is made possible by a coupling part 34 equipped with guide faces 35, with which a receiving part 14 engages, which is provided with complementarily extending receiving jaws 15 and which actuates--in the case of correctly fitting engagement--electrical contacts 18, such that the control elements 10 provided on a control panel 9 for height adjustment of the connection head 1 and/or for supplying the working device 30 with the media needed for operation are released.
