Abstract

See full text

A stretcher for supporting incapacitated individuals that may be selectively positioned by two pairs of hydraulic cylinders located near each end thereof is shown. The piston rods associated with each such pair, located together with their respective cylinders on opposite sides of the stretcher, are mechanically interconnected for stability, while the cylinders associated with such pairs are hydraulically interconnected so that the cylinders can operate in tandem. The cylinder pairs each have their own pumps, operated simultaneously by a foot lever, as well as remotely controlled valving, enabling the pairs to be operated together, or independently of each other. Included pressure relief valving avoids equipment-damaging, excessive hydraulic pressures, and certain adjustable components of the stretcher are provided with spring-loaded tapered lock assemblies which allow the components to be secured in selected positions. X-ray tops are also taught which can be used in conjunction with the stretcher for X-ray examination.
