Patent ID: 8789533

Claim:
A method comprising: providing a bed comprising a frame and a mattress supported by the frame, the bed having a head, a foot, and first and second opposed sides; placing a sheet on the bed, the sheet having a bottom surface that is placed above a supporting surface of the mattress, and a top surface opposite the bottom surface, wherein the bottom surface is at least partially formed of a first material having a first coefficient of friction, and the top surface is at least partially formed of a second material having a second coefficient of friction, and wherein the second coefficient of friction is higher than the first coefficient of friction such that the top surface provides greater slipping resistance than the bottom surface; placing an absorbent pad into contact with the top surface of the sheet, and wherein the second material resists sliding of the pad with respect to the top surface, due to the second coefficient of friction being higher; positioning a patient above the supporting surface of the mattress, such that the supporting surface supports the patient and at least a portion of the patient rests on the absorbent pad; placing a wedge at least partially underneath the sheet, the wedge having a base wall, a ramp surface positioned at an angle to the base wall to form an apex, and a back wall opposite the apex, by inserting the apex of the wedge underneath an edge of the sheet from the first side of the bed such that the base wall confronts the supporting surface of the mattress and the ramp surface confronts the bottom surface of the sheet; and moving the sheet by exerting force on the sheet proximate the edge of the sheet in a direction toward the first side of the bed and transverse to the back wall of the wedge to slide the patient and at least a portion of the sheet at least partially up the ramp surface of the wedge by moving the patient parallel to the ramp surface of the wedge, such that the ramp surface of the wedge partially supports the patient, to cause the patient to lie in an angled position.
