Abstract
A patient transfer device has four casters and two counter-rotating steering wheels. The steering wheels provide a turning path whose center of curvature lies along a transverse centerline of the device. A foot pedal selectively lifts the steering wheels off the floor or brakes them. Another foot pedal at a back end of the device can lock the casters at the front end in a straight direction. The transfer table of the device may be inclined either longitudinally or transversely, and has an upper table whose edge rollers retract to introduce slack in the upper belt so that an air mattress can be inflated. The upper belt selectively disengages from the lower belt using movable, pneumatically-actuated pinch rollers. The outer surface of the upper belt is rough while the outer surface of the lower belt is smooth. The belts are constructed of a material which includes an antimicrobial agent.
