US 5,023,967 A · Patient support system

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.

Dependent claims

A patient support system comprising:

a base frame supportable relative to a floor;
an elongate platform extending along a longitudinal axis and relative to a platform plane generally parallel to the plane of the torso of a patient disposed in a supine or prone position relative to said platform along said longitudinal axis;
and
means for supporting said platform relative to said base frame comprising means defining three axes of pivoting of said platform relative to said frame, characterized in that none of said three axes are perpendicular to said platform plane, and on each axis there exists a first point that is closest to a first of the other axes and a second point, spaced from the first point, that is closest to the second of the other axes, and means for pivoting said platform independently about each of said three axes for varying the pitch, roll and distance of said platform relative to said base frame.

A patient support system comprising:

a base frame supportable relative to a floor;
an elongate platform sized to support thereon a person disposed along a longitudinal axis extending the length of said platform;
and
means for supporting said platform relative to said base frame comprising means defining first and second parallel and spaced apart, generally horizontal axes extending nonparallel to the longitudinal axis of said platform, and means for pivoting said platform independently about each of said first and second axes, whereby the distance between said platform and each of said axes is adjustable, said pivoting means comprising universal joint means interposed between said base frame and said platform, and first and second adjustable-length support arms extending from spaced locations on said base frame to said universal joint means, said first and second support arms respectively being pivotable relative to said base frame about said first and second parallel axes.
