A supply unit with a structural-tubing-type supply beam fastened to a ceiling with supply lines and with a carriage displaceable along the supply beam with a support device for medical treatment instruments. The line routing of the supply lines is extensively hidden, without the displaceability of the carriage being reduced. The supply lines are guided freely displaceably in the form of a loop within the supply beam, and they are deflected via a tube guide to the support device, and that partial lengths L.sub.1 and L .sub.2 of the supply lines within the supply beam are selected to be such that they correspond to a predetermined movement of the carriage.

Supply unit for medical treatment instruments

A ceiling pivot arm to hold equipment that can be rotated, especially medical equipment which is held on a mount through a pivot bearing. Simple assembly of the rotary hinge is possible, whereby it is also easy to make and disassemble the connection between the mount and the pivot arm, so that high functional reliability is produced for operation. To do this, it is provided that the pivot bearing consists of a threaded ring (1) constituting the mount, in whose threads (3, 4) is engaged a threaded collar (2) movable relative to the mount and connected to the pivot arm.

Ceiling pivot arm with a threaded pivot bearing

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.
