## Abstract

A kit for cooling the blood in the carotid arteries includes a cervical immobilization collar and a cooling element. The cooling element may include 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. The cooling material may comprise 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.

## Claims

### Claim 1

A cooling element comprising:
a body-facing panel attached on a body-facing surface;
an outward-facing panel, wherein the body-facing panel and the outward-facing panel form an end;
cooling material disposed between the body-facing panel and the outward facing panel, wherein the cooling material is capable of producing a temperature of 20° F. to 35° F. within a minute of activation at ambient temperature, when measured on the body-facing surface of the body-facing panel, and wherein the cooling material comprises water, urea, and an endothermic ingredient; and
a band attached to the end and configured wrap around a patient.

### Claim 2 (depends on 1)

The cooling element of claim 1, wherein the band comprises a wing that extends from the end.

### Claim 3 (depends on 2)

The cooling element of claim 2, wherein the wing comprises an attachment mechanism.

### Claim 4 (depends on 3)

The cooling element of claim 3, wherein the attachment mechanism is a hook and loop fastener.

### Claim 5 (depends on 1)

The cooling element of claim 1, wherein:
the body-facing panel and the outward-facing panel define an second end;
the band comprises a first wing that extends from the end, and a second wing that extends from the second end; and
the first wing and the second wing attach to one another.

### Claim 6 (depends on 1)

The cooling element of claim 1, wherein the cooling material comprises a greater amount of the urea than the endothermic ingredient by mass.

### Claim 7 (depends on 1)

The cooling element of claim 1, wherein the cooling material comprises at least 45 g of the endothermic ingredient.

### Claim 8 (depends on 1)

The cooling element of claim 1, wherein the cooling material comprises at least about 90 g of the urea.

### Claim 9 (depends on 1)

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

### Claim 10 (depends on 1)

The cooling element of claim 1, wherein the cooling material includes 100 g urea and about 50 g of the endothermic ingredient.

### Claim 11 (depends on 1)

The cooling element of claim 1, wherein the cooling material includes 110 g urea and about 55 g of the endothermic ingredient.

### Claim 12 (depends on 1)

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

### Claim 13 (depends on 1)

The cooling element of claim 1, wherein the body-facing panel is attached on the body-facing surface to a lining layer.

### Claim 14 (depends on 13)

The cooling element of claim 13, wherein the lining layer comprises non-woven material.

### Claim 15 (depends on 14)

The cooling element of claim 14, wherein the lining layer substantially covers the body-facing surface of the body-facing panel and the outward-facing surface of the outward-facing panel.

### Claim 16 (depends on 13)

The cooling element of claim 13, wherein the body-facing panel is attached to the lining layer with an adhesive.
