Thermal pack

A thermal pack comprising a tubular body having a first opening, a second opening, an inner surface and an outer surface, wherein the first opening, the inner surface and the second opening cooperate to define a passage through the tubular body, wherein the inner surface and the outer surface of the tubular body are defined by a continuous eversion-limitless film of flexible material, wherein a non-gaseous temperature retaining fluid that does not become a hard solid at 32° F. is received between the inner surface and the outer surface of the tubular body, wherein a selectively pressurizeable radial air bladder is disposed on the outer surface of the tubular body, and wherein the radial air bladder comprises a plurality of partially-subdivided, interconnected air chambers.

A thermal pack comprising a tubular body having a first opening, a second opening, an inner surface and an outer surface, wherein the first opening, the inner surface and the second opening cooperate to define a passage through the tubular body, wherein the inner surface and the outer surface of the tubular body are defined by a continuous eversion-limitless film of flexible material, wherein a non-gaseous temperature retaining fluid that does not become a hard solid at 32° F. and an insert for inhibiting the displacement of temperature retaining fluid are received between the inner surface and the outer surface of the tubular body, wherein the insert comprises a plurality of sealed pockets that are filled with a temperature retaining fluid and are joined together to form a tubular structure.
