Abstract

1347920 Operating tables NATIONAL RESEARCH DEVELOPMENT CORP 24 July 1972 [7 June 1971] 19187/71 Heading A4J An operating table comprises panels 13, 11, 12, 14 hinged together end-to-end by transverse hinges 15, 16, 17, panel 11 also being hinged to a pedestal 8 by transverse and longitudinal hinges 10, 9, all the hinges being fluid-pressure operated, the fluid-pressure circuits being contained within the hinges and the table support structure 1, 2, 8. The hinges 10, 15, 16, 17 are controlled by rotary members 20, 21, 22, 23 in response to a fluid-pressure differential and are locked in the adjusted position when the differential is removed. Hinge 9 is controlled by a rotary member 19 having a central set position. The table is raised and lowered by a fluid-pressure operated jack (6) controlled by a lever 18 having a central set position to which it is restored to lock the table at the adjusted height. The pedestal 8 is mounted on a base comprising a frame 1 over which a skirt 2 is mounted and is supported on pressure responsive valves which respond to downward pressure on the skirt to arrest table adjustments. Frame 1 includes five legs 3 having castors that can be selectively retracted by jacks operated by a pedal (4) and selectively locked against rotation by brakes operated by a lever (5). End panels 13, 14 can be detached from their hinges 15, 17 by catches (24, 25), and fluid-pressure operated devices can be attached to the exposed hinge leaves and to anchor points (26) on the frame 1. The panels 11-14 are X-ray permeable. The fluidpressure source may be remote from the table and electrically operated, and skirt 2 may house an auxiliary foot pump.
