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.
Claims11
A moldable temperature transfer device comprising:
- (a) an outer water impermeable skin defining a closed container;
- (b) a temperature storage mixture enclosed within said container having a semi-solid dough like consistency over a range of temperatures at least as low as -17.degree. C. and wherein said skin is flexibly deformed over said temperature range, said temperature storage mixture including a phase change prolonging material selected from the group consisting of lithium chlorate, tetradecane, decanol, C-15 through C-16 parafin, tetrahydrofuran and trimethylamine;
- and
- (c) a layer of heat insulating material disposed on a predetermined area of said skin.
A moldable temperature transfer device comprising:
- (a) a water impermeable polymer outer skin defining a closed container;
- (b) a coolant mixture enclosed within said container comprising by volume approximately 55 to 65 percent de-ionized water, 25 to 35 percent propylene glycol, 4, to 10 percent galacto mannans selected from the group consisting of alginate and 1 to 2 percent plant gum selected from the group consisting of locus bean gum, gaur gum, xanthan gum and dextrands;
- (c) layer of radiant energy reflecting material mounted adjacent to a predetermined portion of said skin;
- and
- (d) a layer of heat insulating material disposed in relation to a predetermined portion of said skin.
