ABSTRACT:
A system providing universal support for patients includes an articulated platform supported by a universal joint supported by a pair of hydraulic support arms, and by a pair of lesser hydraulic arms spaced from the universal joint. The platform is comprised of a plurality of relatively hinged panels which are also hydraulically driven. Thus, the platform is capable of assuming a large number of configurations, including full sitting and standing positions. A patient cushion system includes a large plurality of cushions which are individually or severally controlled throgh a valve and manifold system which is computer controlled for cycling cushion pressures between high and low pressures. The sides of the bed platform have restraining members which may be lowered and hinged in toward the patient to provide access to the patient. These restraining members also provide for supplemental support of such things as a canopy or tension weight. Further, a pendulum arm is attachable to the side restraint member for supporting auxiliary equipemnt in an upright position regardless of the orientation of the bed. A sanitary system is incorporated in the cushion system to provide cleansing and removal of bodily wastes. Finally, an extraordinary restraint system, also operable by the cushion system may be provided over the top of the patient to further restrain a patient.
