ABSTRACT:
An air pallet type patient mover, formed principally by top, intermediate and bottom thin flexible sheets sealed together about their edges and defining a plenum chamber between the intermediate and bottom sheets and a backing member cavity between the top sheet and the intermediate sheet with a semi-rigid backing member within the cavity, supports a patient. Low pressure air within the plenum chamber jacks the load and is discharged through pin hole type perforations within the bottom sheet to create a thin air film. Foam strips within the plenum chamber and extending over a substantial lengthwise extent of the plenum chamber insures air distribution through the plenum chamber. Further, foam strips may be positioned within one of the plenum chamber and the backing member cavity along the sides thereof and outside of the semi-rigid sheet to effect padding and eliminate sharp edges which may interfere with X-ray radiation. The pattern of pin hole type perforations may extend only over the head end of the patient mover bottom thin flexible sheet, with a sealed loop area at the center of the foot end about which air flows to jack the patient's legs to the same level as the patient' s torso. Wedge-shaped pillow and foot sections may carry hook and loop type fastener strips end. U-shaped pull straps may be fixed to respective sides of the patient mover.
