Abstract
A patient warming appliqué typically includes a cover layer, a tape layer for releasably securing the appliqué to the patient's skin and an array of encapsulated cells. The encapsulated cells include a chemical heating mechanism beneath the cover layer and a phase change gel sheet between the chemical heating mechanism and the tape layer. The phase change gel sheet is configured to melt and flow when the chemical heating mechanism is activated. The preferred appliqué further includes zones of weakness between the spaced cells allowing the individual cells or a subset of cells to be removed from the appliqué.
