SELF-CONTAINED PERSONAL WARMING APPARATUS AND METHOD OF WARNING

摘要

A self-contained disposable single-use heat generating apparatus comprising a heat generating pack having a first bag layer defined by a first surface area bonded to a second bag layer defined by a second surface area and creating a pouch therebetween. A heat generating agent is disposed within the pouch and adapted to consume air at a predetermined consumption rate in an exothermic reaction. At least a portion of one of the first surface area and the second surface area comprises an air permeable surface area having a predetermined airflow rate such that the heat generating agent remains substantially evenly distributed within the pouch. A method of providing therapeutic heat is also provided.
