Abstract
Abstract A temperature control device containing a mixture of de-ionized water, propylene glycol, polysaccharides and plant gum for providing a moldable pillow-like surface for cooling/heating and positioning body organs or parts. A multi-layered container including an insulator, a radiant heat reflecting layer and a liquid impermeable outer layer permit autoclaving and provide directional cooling/heating. The inclusion of appropriate phase change chemicals or reciprocal ion-type chemicals or metal particles facilitate the stabilization of temperature over a predetermined temperature range.
