This disclosure relates to a brain cooling and spinal cord cooling system, device or mechanism for use in military helmets, and in an adapted format in non-military helmets. The system is comprised of an inflatable pad, or a set of interconnected pads, attached to the interior surface of the helmet, together with a series of valves that allow cooling gases to be delivered from a high pressure canister. The use of different cooling gases permits the achievement and maintenance of cooling of the brain for 24 to 96 hours at a mild (36° C.) or moderate (33° C.-35° C.) brain hypothermia, which is 1.5° C.-4.5° C. below the core temperature.
대표청구항▼
1. A helmet for protection of a user's brain, said helmet comprising: a. a helmet body;b. one or more inflatable pads attached to, but not comprising a surface of, said helmet body, wherein each of the one or more inflatable pads accommodate an expandable gas-filled balloon;c. one or more bi-directi
1. A helmet for protection of a user's brain, said helmet comprising: a. a helmet body;b. one or more inflatable pads attached to, but not comprising a surface of, said helmet body, wherein each of the one or more inflatable pads accommodate an expandable gas-filled balloon;c. one or more bi-directional pressure-sensitive valves;d. a temperature-sensitive probe capable of determining the user's brain temperature; ande. at least one coolant source capable of inflating said inflatable pads with coolant thereby cooling the user's brain; wherein the coolant is a mixture of a liquid and a gas capable of providing a cooling rate to the brain ranging from about 0.1° C. to about 0.5° C./hour. 2. The helmet of claim 1, wherein the helmet is capable of lowering the user's brain temperature to a mean temperature ranging from about 33° C. to about 36° C. 3. The helmet of claim 2, wherein the helmet is capable of maintaining the temperature of the user's brain within the range of about 33° C. to about 36° C. for about 24 hours to about 96 hours. 4. The helmet of claim 3, wherein the helmet is capable of maintaining the temperature of the user's brain within the range of about 33° C. to about 36° C. for about 48 hours to about 72 hours. 5. The helmet of claim 4, wherein the helmet is capable of maintaining the temperature of the user's brain within the range of about 33° C. to about 36° C. for about 48 hours to about 56 hours. 6. The helmet of claim 1, wherein the helmet is capable of cooling the user's brain to a mean temperature of about 33° C. to about 36° C. within about 24 hours. 7. The helmet of claim 1, wherein the helmet is capable of cooling the user's brain to the mean temperature of about 33° C. to about 36° C. within about 48 hours. 8. The helmet of claim 1, wherein the coolant is capable of providing a cooling rate to the user's brain ranging from about 0.1° C. to about 0.4° C./hour. 9. The helmet of claim 1, wherein the coolant is capable of providing a cooling rate to the user's brain ranging from about 0.1° C. to about 0.3° C./hour. 10. The helmet of claim 1, wherein the coolant is capable of providing a cooling rate to the user's brain ranging from about 0.2° C. to about 0.3° C./hour. 11. The helmet of claim 1, wherein the bi-directional pressure-sensitive valves are positioned at the top and lateral sides of the helmet body. 12. The helmet of claim 1, wherein the one or more bi-directional pressure-sensitive valves permits a varying amount of gas flow into the inflatable pads. 13. The helmet of claim 1, further comprising a face-mask attached to the helmet body to create a temperature barrier. 14. The helmet of claim 1, further comprising a visor attached to the helmet body to create a temperature barrier. 15. The helmet of claim 1, further comprising one or more inflatable spinal cord straps. 16. The helmet of claim 1, further comprising a collar adapted to enhance the induction of brain cooling by decreasing the temperature of arterial blood passing through the user's neck. 17. The helmet of claim 1, wherein the helmet provides uniform cooling to the surface area of the user's brain's frontal, parietal and occipital lobes. 18. The helmet of claim 1, wherein the helmet body is a military helmet. 19. The helmet of claim 1, wherein the helmet body is a non-military helmet. 20. A method of treating a user by adapting a helmet body to incorporate a brain cooling system comprising: a. attaching a plurality of inflatable interconnected pads to a helmet body so that the inflatable interconnected pads do not comprise a surface of said helmet body, wherein each of the one or more inflatable pads accommodate an expandable gas-filled balloon;b. incorporating one or more bi-directional pressure-sensitive valves into the helmet body;c. connecting said valves to the inflatable interconnected pads;d. connecting at least one canister containing cooling gases to said valves;e. inflating said inflatable interconnected pads with the cooling gases; andf. monitoring at least one temperature-sensitive probe to determine the user's brain temperature. 21. The method of claim 20, further comprising lowering the user's brain temperature to a mean temperature ranging from about 33° C. to about 36° C. 22. The method of claim 21, further comprising maintaining the temperature of the user's brain within the range of about 33° C. to about 36° C. 23. The method of claim 20, further comprising using a collar to enhance the induction of brain cooling by decreasing the temperature of arterial blood passing through the user's neck. 24. The method of claim 20, further comprising giving the user an anesthetic. 25. The method of claim 20, further comprising giving the user an intravenous saline solution.
