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.

The invention claimed is: 1. A cervical immobilization collar comprising 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, a heat extractor carried by the support structure comprising at least one rupturable membrane, the heat extractor being located within the annular support structure so that when the annular support structure is positioned about the wearer's neck for limiting cervical compaction and cervical rotation of the wearer's neck, the heat extractor is positioned in thermal contact with an anterior portion of the wearer's neck, and the heat extractor being connected to the annular support structure so that changing the position of the support structure from a first position to a second position, in association with the installation of the support structure around the wearer's neck, automatically activates the heat extractor by breaking the rupturable membrane in the heat extractor, producing an endothermic reaction within the heat extractor. 2. The immobilization collar of claim 1, wherein the heat extractor comprises an endothermic pack activated by breaking the at least one rupturable membrane. 3. The immobilization collar of claim 1, wherein the annular support structure is stored in a first position, the first position being an anatomic form close to a form of its intended use and is temporarily distortable into the second position for mounting the support structure on a wearer's neck, wherein a change in the support structure shape associated with the temporary distortion of the support structure from the first position to the second position breaks the at least one rupturable membrane, producing the endothermic reaction. 4. The immobilization collar of claim 1, wherein the annular support structure is subject to an adjustment or securing operation, wherein a change in the support structure shape from the first position to the second position is associated with the adjustment or securing operation and breaks the rupturable membrane, producing the endothermic reaction. 5. The immobilization collar of claim 1, further comprising a sensor arrangement carried by the support structure proximate to the wearers neck for monitoring one or more circulatory parameters, and the sensor arrangement being arranged to monitor at least one of arterial oxygen saturation, heart rate, blood pressure, and blood temperature. 6. The immobilization collar of claim 5, further comprising one or more displays mounted on the support structure for displaying data related to the measured circulatory parameters. 7. The immobilization collar of claim 5, further comprising at east one recording device mounted on the support structure for recording data related to the measured circulatory parameters. 8. The immobilization collar of claim 5, further comprising a communication port mounted on the support structure for transferring data from the one or more sensors to an external device. 9. A protocol for treating trauma patients, comprising: providing a cervical immobilization collar comprising at least one activatable cooling element comprising at least one rupturable membrane, the activatable cooling element located within the cervical immobilization collar so that when the cervical immobilization collar is positioned about the wearer's neck, the activatable cooling element is positioned in thermal contact with an anterior portion of the wearer's neck, installing the cervical immobilization collar around a patient's neck by changing the shape the cervical immobilization collar from a first position, associated with the storage of the cervical immobilization collar, to a second position associated with the installation of the cervical immobilization collar around the wearer's neck, wherein the at least one cooling element is automatically activated when the at least one rupturable membrane is broken by moving the cervical immobilization collar from the first position to the second position. 10. The protocol of claim 9, wherein installing the cervical immobilization collar involves temporarily distorting or otherwise subjecting the cervical immobilization collar to adjustment or securing operations for mounting the collar around the patient's neck. 11. The protocol of claim 9, wherein the first position is an anatomically curved shape for fitting the collar around the patient's neck. 12. The protocol of claim 9, wherein the first position comprises having the cooling element is pre positioned on an inside surface of the cervical immobilization collar and storing the cervical immobilization collar in the first position prior the installation of the collar around the patient's neck. 13. The protocol of claim 12, wherein the cooling element is removably attached to the inside surface of the cervical immobilization collar.
