SELF-CONTAINED PERSONAL WARMING APPARATUS AND METHOD OF WARMING

摘要

A self-contained disposable single-use heat generating apparatus comprising aheat generating pack having a first bag layer defined by a first surface areabonded to a second bag layer defined by a second surface area and creating apouch therebetween. A heat generating agent is disposed within the pouch andadapted to consume air at a predetermined consumption rate in an exothermicreaction. At least a portion of one of the first surface area and the secondsurface area comprises an air permeable surface area having a predeterminedairflow rate such that the heat generating agent remains substantially evenlydistributed within the pouch. A method of providing therapeutic heat is alsoprovided.
