Apparatus and system for turning and positioning a patient
A system for use with a bed having a frame and a supporting surface includes a sheet having a bottom surface placed above the supporting surface of the bed, a top surface, and a plurality of tether straps connected to and extending from the sheet. Each tether strap is configured for connection to the bed. The bottom surface is at least partially formed of a low friction material, and the top surface is at least partially formed of a high friction material, such that the top surface provides greater slipping resistance than the bottom surface. The tether straps include at least two pairs of tether straps, with one pair connected proximate a top edge of the sheet and another pair connected proximate a bottom edge of the sheet. The sheet may further include a sliding member on the bottom surface to assist in lateral sliding of the sheet.
1. An apparatus for use with a bed having a frame and a supporting surface supported by the frame, the apparatus comprising:
a sheet having a top surface and a bottom surface, each of the top surface and bottom surface defined by a top edge and a bottom edge, which are respectively configured for positioning proximate a first end and a second end of a bed; and
at least one sliding member connected to the bottom surface of the sheet, the at least one sliding member having a fixed portion and a free portion, wherein the free portion is configured to slide against the bottom surface within a range of movement in a first direction, and wherein at least a portion of the bottom surface of the sheet is configured to slide against the sliding member within the range of movement of the at least one sliding member when the sheet is moved along the first direction;
wherein the fixed portion is fixed to the bottom surface of the sheet along a first connection line and a second connection line parallel to the first connection line;
wherein the free portion is disposed between the first and second connection lines;
wherein the sliding member is connected to the bottom surface of the sheet only along the first connection line and the second connection line;
wherein the first direction is perpendicular to the first connection line; and
wherein the range of movement of the at least one sliding member is determined by a lateral width of the at least one sliding member and a distance between the first and second connection lines.
2. The apparatus of claim 1 , further comprising a plurality of tether straps connected to the sheet and extending from the sheet, each tether strap being configured for connection to the bed, wherein the plurality of tether straps comprise at least a first pair of tether straps connected proximate at least one of the top edge of the sheet or the bottom edge of the sheet opposite the top edge.
3. The apparatus of claim 2 , wherein each tether strap comprises an elastic portion and a non-elastic portion each forming a portion of a length of the tether strap, wherein the elastic portion is connected at one end to the sheet and the elastic portion is connected at another end to the non-elastic portion, and the non-elastic portion is configured for connection to the bed.
4. The apparatus of claim 1 , wherein the at least one sliding member is configured such that the free portion is configured to slide against the bottom surface within a range of movement in a second direction, and wherein the range of movement in the second direction is less than the range of movement in the first direction.
5. The apparatus of claim 1 , wherein the at least one sliding member is formed as a tube.
6. The apparatus of claim 5 , wherein the at least one sliding member has a central passage parallel to the first and second first connection lines, and wherein the at least one sliding member has opposing ends that are open to the central passage.
7. The apparatus of claim 1 , wherein the at least one sliding member is formed as a loop.
8. The apparatus of claim 1 , wherein the at least one sliding member is connected to the sheet at a location configured to support a center of mass of a patient.
9. The apparatus of claim 1 , wherein an area of contact between the at least one sliding member and the sheet has a width less than half the sum of the width of the at least one sliding member and the distance between the first and second connection lines.
