ABSTRACT:
One aspect of the invention is a cooling pillow comprising a flexible pouch and thermal transfer fluid composition hermetically filled in the pouch. A second aspect of the invention is a cooling device which comprises a pad having a flexible pouch and a thermal transfer fluid composition hermetically filled in the pouch, and means for holding the pad therewith to bring the pad in contact with the human body. The fluid composition comprises a mixture of fine particles of hard or graphitic carbon having good thermal conductivity and water. Sodium chloride, surface active agents, bactericides and preservatives may be further added to the composition. Since the carbon particles have good thermal conductivity, the fluid readily reaches a temperature close to ambient temperatures and can gently cool the human body. Long use allows the body to be continuously cooled down to a temperature close to the ambient temperature.
