A patient support apparatus comprises a base frame (10) supporting radius arms (15) on either side. The radius arms (15) support an upper frame (20), via cross tubes (16). Linear actuators (30, 31) act on the cross tubes (16) to raise, lower or tilt the upper frame (20). Further linear actuators (32, 33) are provided to profile platform sections (41, 42, 43). The actuators, their control systems, power and other functions e.g. patient weighing, air pumps, lights are all mounted centrally on the upper frame and housed within a single housing located almost entirely within the upper frame. The location of the actuators and housing provide a very low minimum height of the patient support apparatus, the single housing eliminating trailing cables and wires and ensuring easy cleaning and maintenance. |
