Abstract
A patient support apparatus includes a base, a litter frame, and an elevation mechanism interconnecting the base to the litter frame and being configured to effect changes in elevation of the litter frame relative to the base. The elevation mechanism includes a pair of hydraulic actuators, each actuator covered by a telescoping shroud. The telescoping shroud is connected to the base and to the litter frame by a number of biased catches. The litter frame includes a pair of laterally spaced and longitudinally extending support rails and a plurality of laterally extending support rails interconnecting the longitudinally extending support rails so that the litter frame has a rectangular configuration. The litter frame includes a thigh section configured to be raised and lowered by use of one of a manually pumped hydraulic actuator or a gas-spring assisted lever actuator.
