ABSTRACT:
A cold compress for application to a portion of a human or animal body. The compress comprises a tough flexible envelope which sealingly encloses a thin gellike pad. The pad incorporates a coagulated gel which maintains its properties over a wide temperature range, including temperatures below 32.degree. F. to permit super cooling of the pad. The coagulated gel is substantially solid and self-supporting throughout the usable temperature range. A thin insulator pad is directly attached to one surface of the gel pad to facilitate convenient use of the compress.
