Abstract
A patient trolley has a tiltable upper body support which is hydraulically lifted to a raised "heart" position and which is immediately lowered by a quick release valve so that a patient may be quickly treated in a horizontal position. Two cylinders are mounted on trunnions with distal ends of pistons interconnected to upper body supports so that the cylinders extend downward and toward a head end of the trolley from the trunnions. As the upper body support is lifted the cylinders rotate on the trunnions toward the head end of the trolley. In the down position of the upper body support the cylinders and trunnions may be lifted and held in an inactive position for clearance of hospital equipment. Levers and linear bearings enable the upper body support to be raised to substantially perpendicular position and to be quickly lowered.
