Abstract

A temperature management pad includes a patient facing side, a cushioning layer for supporting the patient facing side above a surface, a cooling component located in, on, or adjacent the cushioning layer for cooling the patient facing side of the pad for cooling a patient lying thereon, wherein the cooling component includes a conduit formed between the patient facing side and the cushioning layer for circulating fluid through the pad across the cushioning layer. The cushioning layer comprises a gel cushioning layer with a continuous upper surface supporting the patient facing side, which includes channels formed therein. The conduit is supported in the channels for circulating fluid laterally across the gel cushioning layer and through the pad.

Claims

1. A temperature management pad comprising:

a patient facing side;

a cushioning layer for supporting said patient facing side above a surface;

a cooling component located in, on, or adjacent said cushioning layer for cooling the patient facing side of the pad for cooling a patient lying thereon, wherein said cooling component includes a conduit formed between said patient facing side and said cushioning layer for circulating fluid through said pad across said cushioning layer;

wherein said cushioning layer comprise a gel cushioning layer, said gel cushioning layer having a continuous upper surface supporting said patient facing side, and said continuous upper surface having channels formed therein, and

said conduit supported in said channels for circulating fluid laterally across said gel cushioning layer and through said pad.

2. A temperature management pad according to claim 1, wherein said gel layer comprises a flowable gel.

3. The temperature management pad according to claim 2, wherein said flowable gel comprises a flowable gel with a plurality of spherical bodies.

4. A temperature management pad according to claim 1, wherein said patient facing side is formed from a film.

5. A temperature management pad according to claim 4, wherein said film comprises a flexible polymeric film, such as polyester and polyether polyurethane film.

6. The temperature management pad according to claim 5, wherein said flexible polymeric film comprises a polymeric film selected from the group consisting of polyester, polyether polyurethane film, PVC film, neoprene film, and polyethylene film.

7. The temperature management pad according to claim 4, wherein said film comprises a first film, further comprising a second film, said upper side of said gel layer supporting said second film to thereby form at least part of the cooling component, and said first film and said second film forming said cooling component.

8. A temperature management pad comprising:

a patient facing side;

a cushioning layer for supporting said patient facing side above a surface;

a cooling component located in, on, or adjacent said cushioning layer for cooling the patient facing side of the pad for cooling a patient lying thereon; and

wherein the cushioning layer includes a support surface facing side and a plurality of walls at said support facing side for supporting said pad on the surface.

9. A temperature management pad according to claim 8, wherein said walls are configured to locally buckle under a pressure of a predetermine magnitude.

10. A temperature management pad according to claim 9, wherein said walls intersect to form a grid.

11. A temperature management pad comprising:

a patient facing side;

a cushioning layer for supporting said patient facing side above a surface;

a cooling component located in, on, or adjacent said cushioning layer for cooling the patient facing side of the pad for cooling a patient lying thereon;

wherein said patient facing side is formed from a first film, said first film comprising a flexible polymeric film; and

said patient facing side further comprising a second film, said films forming the boundaries of a conduit.

12. A temperature management pad according to claim 11, wherein said cushioning layer comprises a foam, gel, or a plurality of air bladders.

13. A temperature management pad according to claim 12, wherein said cushioning layer comprises gel.

14. A temperature management pad according to claim 13, wherein said gel comprises a structural gel.

15. A temperature management pad according to claim 11, wherein said second film comprises a flexible polymeric film.

16. The temperature management pad according to claim 15, wherein said second film comprises a polyester film, a polyether polyurethane film, a PVC film, a neoprene film, or a polyethylene film.

17. A temperature management pad according to claim 11, wherein said cushion layer includes a least one channel formed in the side of the cushion layer facing said second film wherein said second film extends into said channel.

18. A temperature management pad according to claim 11, wherein said cushioning layer at least partially prevents said conduit from being occluded by the weight of a patient supported on said pad.

19. The temperature management pad according to claim 11, wherein said first film comprises a polyester film, a polyether polyurethane film, a PVC film, a neoprene film, or a polyethylene film.

20. A temperature management pad comprising:

a gel cushioning layer having a continuous upper surface for supporting a patient above a support surface;

a conduit extending laterally across said gel layer for circulating fluid through said pad; and

wherein said gel cushioning layer includes a support surface facing side and a plurality of walls at said support facing side for supporting said pad on said support surface.

21. A temperature management pad according to claim 20, wherein said walls are configured to locally buckle under a pressure of a predetermine magnitude.
