Patient repositioning sheet, system, and method

1. A patient repositioning sheet comprising:

an inflatable sheet having a lower layer and an upper layer that are urged apart with inflation of the inflatable sheet;

at least one inflatable support of the inflatable sheet; and

a surface portion of the inflatable support that extends obliquely to the upper layer of the inflatable sheet with the inflatable support inflated, the inflatable sheet mounted to a cover layer of the inflatable sheet such that the cover layer extends about the inflatable support and a portion of the cover layer forms a lower portion of the inflatable support, the cover layer made of a high-friction material for engaging a patient and inhibiting movement of the patient relative to the inflatable sheet.

2. The patient repositioning sheet of claim 1 wherein the inflatable support includes an inflatable wedge.

3. The patient repositioning sheet of claim 1 wherein the inflatable support comprises an upper wall including the surface portion, a plurality of side walls, and a plurality of baffles; and

wherein the upper wall, side walls, and baffles are joined to the cover layer.

4. The patient repositioning sheet of claim 1 wherein the inflatable support includes an inflatable wedge comprising:

an upper wall including the surface portion;

triangular end walls;

a rectangular side wall; and

a plurality of baffles.

5. The patient repositioning sheet of claim 1 wherein the inflatable support is configured to be inflated and deflated independently of the inflatable sheet.

6. The patient repositioning sheet of claim 1 wherein the inflatable support comprises an upper wall including the surface portion, the upper wall including an air-permeable material.

7. The patient repositioning sheet of claim 6 wherein the inflatable support comprises a plurality of side walls connected to the upper wall, the side walls made of a material with an air permeability less than the air permeability of the upper wall.

8. The patient repositioning sheet of claim 1 wherein the inflatable support includes a plurality of walls defining an interior volume of the inflatable support; and

wherein the inflatable support includes an air inlet in communication with the interior volume of the inflatable support.

9. The patient repositioning sheet of claim 1 wherein the at least one inflatable support includes a pair of inflatable supports on opposite sides of the inflatable sheet.

10. The patient repositioning sheet of claim 9 wherein the inflatable supports each include an air inlet.

11. The patient repositioning sheet of claim 1 wherein the inflatable support includes a plurality of baffles, a plurality of chambers separated by the baffles, and a side wall;

the baffles having end portions spaced from the side wall by gaps to permit airflow between the chambers.

12. The patient repositioning sheet of claim 1 wherein the surface portion of the inflatable support extends at an angle of approximately thirty degrees relative to an adjacent portion of the upper layer of the inflatable sheet with the inflatable support in an inflated configuration.

13. The patient repositioning sheet of claim 1 wherein the cover layer includes a microfiber material.

14. The patient repositioning sheet of claim 1 wherein the cover layer is laminated to the upper layer of the inflatable sheet.

15. The patient repositioning sheet of claim 1 further comprising an incontinence pad on the cover layer.

16. The patient repositioning sheet of claim 1 wherein the inflatable sheet is mounted to a cover layer of the inflatable sheet such that the cover layer extends about the inflatable support, wherein the inflatable support includes an inflatable wedge and the surface portion includes a wedge surface of the inflatable wedge.
