Patent attributes
The invention provides an improved hot/cold therapy pad consisting of a thermally conductive fluid and a discrete matrix insert contained within an outer envelope. The matrix insert has significant void space (over 50%) and is chemically inert relative to the other components within the envelope. The matrix has low bulk density and may be formed by bonding fibers together to form a mat. This matrix serves to reduce the flow of the thermally conductive fluid and provide for more effective and consistent heat (cold) transfer from the pad to the skin. The thermally conductive fluid has a viscosity greater than water and is stable over the typical range of hot/cold therapy applications. The invention eliminates saddle-bagging in hot and cold therapy applications.
