Arterial cooling elements for use with a cervical immobilization collar

1. A cooling element comprising:

a body-facing panel attached on a body-facing surface to a lining layer, an outward-facing panel, and cooling material disposed between the body-facing panel and the outward facing panel; wherein the cooling material comprises urea and Carbamakool in an amount sufficient to produce a temperature of 20° F. to 35° F. within a minute of activation when measured on the body-facing surface of the body-facing panel.

2. The cooling element of claim 1 , wherein the cooling material maintains the temperature for a period of about 15 to about 30 minutes.

3. The cooling element of claim 1 , wherein the cooling material includes about 90 to about 110 g urea and about 45 to about 55 g Carbamakool.

4. The cooling element of claim 3 , wherein the cooling material includes 100 g urea and about 50 g Carbamakool.

5. The cooling element of claim 3 , wherein the cooling material includes 110 g urea and about 55 g Carbamakool.

6. The cooling element of claim 1 , wherein the lining layer comprises non-woven material and substantially covers the body-facing surface of the body-facing panel and the outward-facing surface of the outward-facing panel.

7. The cooling element of claim 6 , wherein the body-facing panel is attached to the lining layer with an adhesive.

8. The cooling element of claim 1 , wherein the lining layer comprises non-woven material.

9. A kit for cooling the blood in the carotid arteries comprising:

a cooling element, wherein the cooling element comprises a body-facing panel attached on a body-facing surface to a lining layer, an outward-facing panel, and cooling material disposed between the body-facing panel and the outward facing panel; wherein the cooling material comprises urea and Carbamakool in an amount sufficient to produce a temperature of 20° F. to 35° F. within a minute of activation when measured on the body-facing surface of the body-facing panel; and

a cervical immobilization collar comprising a substantially annular support structure having an extended axial length and an anterior opening that is coverable with a door.

10. The kit of claim 9 , wherein the cooling material maintains the temperature for a period of about 15 to about 30 minutes.

11. The kit of claim 9 , wherein the cooling material includes about 90 to about 110 g urea and about 45 to about 55 g Carbamakool.

12. The kit of claim 11 , wherein the cooling material includes 100 g urea and about 50 g Carbamakool.

13. The kit of claim 11 , wherein the cooling material includes 110 g urea and about 55 g Carbamakool.

14. The kit of claim 9 , wherein the lining layer comprises non-woven material and substantially covers the body-facing surface of the body-facing panel and the outward-facing surface of the outward-facing panel.

15. The kit of claim 9 , wherein the body-facing panel is attached to the lining layer with an adhesive.

16. The kit of claim 9 , wherein the lining layer comprises non-woven material.

17. The kit of claim 9 , wherein the door includes a body-facing surface and an outward-facing surface, the body-facing surface of the door having at least one pressure member.

18. The kit of claim 17 , wherein the at least one pressure member comprises two foam members disposed on the body-facing side of the door and wherein the two foam members are configured to exert pressure on the cooling element in a position relative to a patient's carotid arteries.

19. The kit of claim 9 , wherein the door has a shape that is substantially similar to a shape of the anterior opening.

20. The kit of claim 19 , wherein the cooling element is configured to be received in the anterior opening of the substantially annular support structure.
