ABSTRACT:
A patient support apparatus such a surgical table or a stretcher is provided. The apparatus includes a top assembly for supporting a patient in a variety of selected positions. The top assembly is supported by first and second hydraulic column assemblies which are, in turn, mounted to a base assembly. A stabilizing mechanism is provided for exerting a constant downward force upon the hydraulic column assembly supporting the head end of the top assembly. The stabilizing mechanism counteracts the lifting force at the head end of the apparatus when a patient's weight is located at or beyond the foot end thereof. The stabilizing mechanism includes a gas spring which is mounted to the base assembly and a cable connected between the base assembly and top assembly. The gas spring exerts a constant force upon the cable in all elevational positions of the top assembly.
