Abstract

A patient positioning system for use with a patient on a bed includes a sheet having a bottom surface configured to be placed above the supporting surface of the bed and a top surface opposite the bottom surface, and a wedge having a base wall, a ramp surface, and a back wall, with the ramp surface joined to the base wall to form an apex. The wedge is positioned under the sheet such that the base wall confronts the supporting surface of the bed and the ramp surface confronts the bottom surface of the sheet. The bottom surface of the sheet and the ramp surface of the wedge have engagement members forming a selective gliding assembly that resists movement of the sheet with respect to the wedge in at least one direction and permits movement of the sheet with respect to the wedge in at least one other direction.

First claim

What is claimed is:

1. 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 configured to be placed above the supporting surface of the bed and a top surface opposite the bottom surface, the sheet having a sheet engagement member positioned on the bottom surface; and
a wedge comprising a wedge body having a base wall, a ramp surface, and a back wall, the ramp surface joined to the base wall to form an apex, wherein the ramp surface has a first and a second ramp engagement member;
wherein the wedge is configured to be positioned under the sheet such that the base wall confronts the supporting surface of the bed and the ramp surface confronts the bottom surface of the sheet,
wherein the first ramp engagement member is configured to engage the sheet engagement member to form a selective gliding assembly that resists movement of the sheet with respect to the ramp surface in a first direction, such that a first pull force necessary to create sliding movement of the sheet with respect to the ramp surface in the first direction is greater compared to a second pull force necessary to create sliding movement of the sheet with respect to the ramp surface in a second direction that is different from the first direction; and
wherein the second ramp engagement member is configured to engage the sheet engagement member to further form the selective gliding assembly to resist movement of the sheet with respect to the ramp surface in a third direction different from the first and second directions, such that a third pull force necessary to create sliding movement of the sheet with respect to the ramp surface in the third direction is greater compared to the second pull force.

2. The system of claim 1 , wherein the second direction is transverse to the first direction.

3. The system of claim 1 , wherein the second direction is at an angle of 90° or 180° to the first direction.

4. The system of claim 1 , wherein the ramp engagement member and the sheet engagement member comprise a directional stitching material, and wherein the second ramp engagement member comprises a directional glide material.

5. The system of claim 1 , wherein the third direction is at an angle of 90° or 180° to the first direction.

6. The system of claim 1 , wherein the first direction is parallel to at least one of the apex and the back wall of the wedge, the second direction extends from the apex toward the back wall of the wedge, and the third direction extends from the back wall toward the apex of the wedge.

7. The system of claim 1 , wherein the sheet comprises a first piece of a first material having a first coefficient of friction and a second material connected to the first piece, the second material having a second coefficient of friction, wherein the second material 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 in at least one direction than the bottom surface.

8. The system of claim 1 , wherein the sheet further comprises a wipeable material covering at least a portion of the top surface of the sheet.

9. The system of claim 1 , wherein the wedge further comprises a base engagement member on the base wall, configured to engage a surface of the bed to form a second selective gliding assembly that resists movement of the wedge with respect to the bed in at least one direction.

10. The system of claim 9 , wherein the second selective gliding assembly resists movement of the wedge with respect to the bed in a direction extending from the apex toward the back wall of the wedge.

11. The system of claim 1 , further comprising a support connected to the wedge and extending from the apex and configured to be positioned under the sheet beneath an upper thigh area of a patient, such that a bottom surface of the support confronts the supporting surface of the bed and a top surface of the support confronts the bottom surface of the sheet and the patient.

12. The system of claim 1 , further comprising:
a second wedge comprising a second wedge body 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, wherein the second ramp surface has a second ramp engagement member;
wherein the second wedge is configured to be positioned under the sheet such that the second base wall confronts the supporting surface of the bed and the second ramp surface confronts the bottom surface of the sheet, and
wherein the second ramp engagement member is configured to engage the sheet engagement member to form a second selective gliding assembly that resists movement of the sheet with respect to the second ramp surface in a third direction, such that a third pull force necessary to create sliding movement of the sheet with respect to the second ramp surface in the third direction is greater compared to a fourth pull force necessary to create sliding movement of the sheet with respect to the second ramp surface in a fourth direction.

13. The system of claim 12 , wherein the sheet engagement member comprises a first piece of directional stitching material configured to engage the ramp engagement member of the wedge and a second piece of directional stitching material configured to engage the second ramp engagement member of the second wedge.

14. 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 configured to be placed above the supporting surface of the bed and a top surface opposite the bottom surface, the sheet having a sheet engagement member positioned on the bottom surface; and
a wedge comprising a wedge body having a base wall, a ramp surface, and a back wall, the ramp surface joined to the base wall to form an apex, wherein the ramp surface has a ramp engagement member;
wherein the wedge is configured to be positioned under the sheet such that the base wall confronts the supporting surface of the bed and the ramp surface confronts the bottom surface of the sheet,
wherein the ramp engagement member is configured to engage the sheet engagement member to form a selective gliding assembly that resists movement of the sheet with respect to the ramp surface in a first direction, such that a first pull force necessary to create sliding movement of the sheet with respect to the ramp surface in the first direction is greater compared to a second pull force necessary to create sliding movement of the sheet with respect to the ramp surface in a second direction that is different from the first direction; and
a support connected to the wedge and extending from the apex and configured to be positioned under the sheet beneath an upper thigh area of a patient, such that a bottom surface of the support confronts the supporting surface of the bed and a top surface of the support confronts the bottom surface of the sheet and the patient;
wherein the support further comprises a support engagement member configured to engage the sheet engagement member to form a second selective gliding assembly that resists movement of the sheet with respect to the support in a direction extending parallel to at least one of the apex and the back wall of the wedge.

15. 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 configured to be placed above the supporting surface of the bed, a top
