Abstract
A passive rewarming article for use with traumatized individuals, e.g. those victims suffering from hypothermia, shock, or expsure is made from a closed-cell foam material. The preferred rewarming article comprises a body portion, at least one independent side flap, a foot flap, and a detachable head pocket. The rewarming article is enconomical to construct, yet provides high body heat retention capability under both wet and dry conditions.
Claims20
A passive rewarming article for use with an accident victim under a wide range of environmental conditions, said article constructed from a closed-call foam material having a thermal conductivity of less than about 0.30 BTU/in./hr./.degree.F./square ft. and ranging in thickness from about 0.10 inches to about 1.0 inches with a fibrous backing for adding strength and tear resistance to the article, further wherein the article is in a form capable of substantially completely encasing the victim with the closed- cell foam and having closure means permanently attached to the article for ensuring the article retains the shape it assumes when the victim is encased thereby.
A passive rewarming article for use with accident victims, said article constructed from a closed-cell foam material having a thermal conductivity of less than about 0.30 BTU/in./hr./.degree.F./square ft. with a fibrous backing comprising:
- (a) a body portion made from the closed-cell foam sufficiently large to accommodate at least the torso of an adult victim when laid upon said body portion;
- (b) at least one independent side flap on each side of the body portion, said flaps made from the closed-cell foam and sufficiently large enough to laterally fold over and cover the victim's torso and upper legs;
- (c) a foot flap made from the closed-cell foam extending from a first end of the body portion sufficiently large enough to longitudinally fold over and cover the feet of the victim;
- and
- (d) a head pocket made from the closed-cell foam capable of attachment to the body portion at a second end, said head pocket dimensioned to slip over the victim's head and having a cut-out for exposing at least the victim's eyes.
