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 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.

Abstract: A kit and method for cooling the carotid arteries includes cervical immobilization collar includes a substantially annular support structure having an extended axial length, at least two cheek support structures having an extended vertical length, and an anterior opening that may be covered with a door. The door has a body-facing surface on which a pressure member may be secured and an outward-facing surface. The kit and method also includes a cooling element that may be disposed within the anterior opening and can be secured to the substantially annular support structure by placing the cooling element between the anterior portion of a patient's neck and the pressure member located on the door.

Abstract: A kit and method for cooling the carotid arteries includes cervical immobilization collar includes a substantially annular support structure having an extended axial length, a chin rest, at least two cheek support structures having an extended vertical length, and an anterior opening that may be covered with an anterior removable door. The door has a body-facing surface and an outward-facing surface, the body-facing surface on which the pressure member is secured. The kit and method also includes a cooling element that may be disposed within the anterior opening and can be secured to the substantially annular support structure by placing the cooling element between the anterior portion of a patient's neck and the pressure member located on the door.

Abstract: A cervical immobilization collar incorporates one or more cooling elements for inducing a mild cerebral hypothermia by transcutaneous cooling of oxygenated blood flowing through carotid arteries. The immobilization collar includes an annular support structure having an extended axial length for limiting cervical compaction of a wearer's neck and a chin rest for limiting cervical rotation of the wearer's neck. In addition, the one or more cooling elements, which function as a heat extractor, are carried by the support structure in positions for inducing transcutaneous conduction of heat through an anterior portion of the wearer's neck from at least one of the wearer's carotid arteries.
