Abstract

A technique for heating a patient is provided. The technique includes providing a warming blanket comprising at least one section that can be moved relative to the remainder of the warming blanket to define an opening in the warming blanket. The technique also includes providing a drape suitable to cover the opening such that a seal is formed between the drape and the warming blanket along the periphery of the opening.

Claims (30)

1. A warming assembly, comprising:

a warming blanket comprising at least one section that can be moved relative to the remainder of the warming blanket to define an opening in the warming blanket; and

a drape suitable to cover the opening such that a seal is formed between the drape and the warming blanket along the periphery of the opening.

2. The warming assembly of claim 1 , comprising a heated air blower configured to provide heated air to the warming blanket.

3. The warming assembly of claim 1 , wherein the at least one sections are provided as one or more arrays of sections.

4. The warming assembly of claim 1 , wherein each section is defined by perforations that, once broken, allow the respective section to move relative to the remainder of the warming blanket.

5. The warming assembly of claim 1 , wherein the drape comprises a sterile drape suitable for surgery.

6. The warming assembly of claim 1 , wherein the warming blanket comprises a first sheet and a second sheet.

7. The warming assembly of claim 6 , wherein the first sheet and the second sheet are sealed together along a common perimeter.

8. The warming assembly of claim 6 , wherein the first and second sheet are attached by welds within the interior of the warming blanket.

9. The warming assembly of claim 6 , wherein the first sheet comprises a polypropylene composition and the second sheet comprises a polyester composition.

10. The warming assembly of claim 6 , wherein a polyethylene film covers interior surfaces of the first sheet and the second sheet.

11. A method for warming a patient, comprising:

placing a warming blanket on a patient;

moving a movable section of the warming blanket to an open position to expose a region on the patient;

covering the region with a drape such that a seal is formed between the warming blanket and the drape; and

providing warmed air to the warming blanket.

12. The method of claim 11 , wherein moving the movable section comprises folding at least one panel in an array of panels.

13. The method of claim 11 , comprising breaking one or more perforations proximate to the movable section.

14. The method of claim 11 , wherein providing warmed air to the warming blanket comprises blowing warmed air into an interior space defined by a first sheet and a second sheet sealed together along their perimeters.

15. A warming assembly, comprising:

a warming blanket comprising an array of folding panels that can be moved relative to the remainder of the warming blanket; and

a drape suitable to cover an opening defined by one or more of the folding panels when folded, wherein a seal is formed between the drape and the warming blanket along the periphery of the opening.

16. The warming assembly of claim 15 , comprising a heated air blower configured to provide heated air to the warming blanket.

17. The warming assembly of claim 15 , wherein each folding panel is defined by perforations that, once broken, allow the respective folding panel to move relative to the remainder of the warming blanket.

18. The warming assembly of claim 15 , wherein the drape comprises a sterile drape suitable for surgery.

19. The warming assembly of claim 15 , wherein the warming blanket comprises a multi-layer structure.

20. The warming assembly of claim 19 , wherein the multi-layer structure is sealed together along its perimeter.

21. The warming assembly of claim 19 , wherein the multi-layer structure is internally attached by welds.

22. The warming assembly of claim 19 , wherein the multi-layer structure comprises a polypropylene layer and a polyester layer.
