SEMI-RIGID AIR PALLET TYPE PATIENT MOVER ABSTRACT OF THE DISCLOSURE An air pallet type patient mover is formed by top (12), intermediate (14) and bottom (16) thin flexi- ble sheets of electrically conductive sheet material stitched along given lines by conductive thread to define at least a plenum chamber (24) between the intermediate thin flexible sheet (14) and the bottom thin flexible sheet (16) and a semi-rigid backing member (18) cavity (20) defined by the top (12) and intermediate (14) thin flexible sheets. Completely sealed high pressure tubes (72, 74) formed by the top (12) and intermediate thin flexible sheets (14) pressurized at relatively high air pressure may consti- tute the backing member for the patient mover. Alternatively, the tubes (80, 83) may receive low pres- sure low air flow prior to that air flow passing to the plenum chamber (24) and discharging through a plurality of closely spaced small diameter pinhole type perfora- tions (56) opening directly into the plenum cham- ber (24) and outwardly onto an underlying fixed support surface (38). Preferably, the perforations (56) form a diamond shaped pattern beneath the imprint of the load. A semi-rigid sheet (18) of a length less than the plenum chamber (24) of an effective width less than the plenum chamber (24) facilitates frictionless movement of a patient (P) over a soft and depressible support surface (38) such as that formed by a hospital bed mattress, which semi-rigid sheet (18) overlies and encompasses the diamond shaped pattern of perfora- tions (56) within the bottom thin flexible sheet (16).
