Abstract:
1. A hypothermia treatment sack for temporarily preventing and managing hypothermia in field conditions, comprising: a top sheet having a generally rectangular shape for covering a patient's body; a bottom sheet having a corresponding rectangular shape to said top sheet for engaging said top sheet to form a patient receiving cavity between said top and bottom sheets; said top and bottom sheets each having a weatherproof exterior side for repelling wind and water from entering said patient receiving cavity, and a heat reflective interior side for preventing heat from escaping said patient receiving cavity; and, a plurality of self-activating heating pads carried in said top sheet for producing heat when exposed to air, wherein said heating pads have a first side exposed on said weatherproof exterior side of said top sheet for being in direct communication with air surrounding said top sheet to provide a generally unrestricted airflow to said heating pads, and a second side of said heating pads exposed on said heat reflective interior side of said top sheet for being in direct communication with said patient receiving cavity to radiate heat directly into said patient receiving cavity to warm a patient placed therein.
