Therapeutic brain cooling system and spinal cord cooling system

Abstract

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 DEG C) or moderate (33 DEG C-35 DEG C) brain hypothermia, which is 1.5 DEG C-4.5 DEG C below the core temperature.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application 61 / 359,476, filed June 29, 2010. technical field [0003] The present disclosure relates to protective headgear, such as helmets that can act as brain cooling systems and spinal cord cooling systems, devices or mechanisms for use with helmets, particularly to ameliorate the long-term consequences of hypoxic-ischemic or traumatic brain and spinal cord injuries. The drop in temperature must be relatively slow, ie less than about 0.5°C / hr, to prevent cardiac arrhythmias and maintain blood homeostasis. Background technique [0004] The skull is hard and inflexible, while the brain is soft and has the consistency of gelatin. The brain is enclosed within the skull. Movement of the skull through space (acceleration) followed by a quick stop (deceleration) when the skull encounters a stationary object causes the brain to move within the skull. The brain move...

Additionally, the system needs to be highly mobile and needs to be integrated into the user's current equipment, meaning that the system or device should not obstruct the user, impair the functionality of the user's current equipment, or otherwise prone to failure by accidental damage prior to activation
