Apparatus and system for turning and positioning a patient

A system for use with a bed having a frame and a supporting surface supported by the frame, the system comprising:

• a sheet having a bottom surface adapted to be placed above the supporting surface of the bed and a top surface opposite the bottom surface, the sheet comprising a first piece of a first material having a first coefficient of friction and a second piece of a second material connected to the first piece, the second material having a second coefficient of friction, wherein the first piece forms at least a majority portion of the bottom surface and the second piece forms at least a portion of the top surface, 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, the sheet further comprising at least one first handle located proximate a first edge of the sheet and at least one second handle located proximate a second edge of the sheet opposite the first edge;
• a tether strap connected to the sheet and extending from the sheet, wherein the tether strap comprises an elastic portion and a non-elastic portion each forming a portion of a length of the tether strap, such that the elastic portion and the non-elastic portion each spans at least a portion of a distance between the sheet and the fastener;
• a first wedge comprising a first wedge body formed at least partially of a compressible material and having a first base wall, a first ramp surface, and a first back wall, the first ramp surface joined to the first base wall to form a first apex and positioned at an angle of approximately 15-35 degrees to the first base wall, wherein the first ramp surface is at least partially formed of a third material having a third coefficient of friction and the first base wall is at least partially formed of a fourth material having a fourth coefficient of friction, and wherein the fourth coefficient of friction is higher than the third coefficient of friction;
• and
• a second wedge comprising a second wedge body formed at least partially of the compressible material and having a second base wall, a second ramp surface, and a second back wall, the second ramp surface joined to the second base wall to form a second apex and positioned at an angle of approximately 15-35 degrees to the second base wall, wherein the second ramp surface is at least partially formed of the third material and the second base wall is at least partially formed of the fourth material,
• wherein the first and second wedges are configured to be positioned under the sheet such that the first and second base walls confront the supporting surface of the bed and the first and second ramp surfaces confront the bottom surface of the sheet, and wherein the first and second base walls are adapted to have higher resistance to sliding of the first and second wedges with respect to the supporting surface of the bed as compared to a sliding resistance of the first and second ramp surfaces with respect to the bottom surface of the sheet, due to the higher fourth coefficient of friction of the fourth material.
