Abstract
A thermal blanket particularly suitable for post-operative treatment of the ankle and foot. The blanket includes inner and outer panels of easily foldable material having an outline defining two foot sections, an ankle section, and a T-shaped leg encircling section. The outer panel has its entire outer surface formed of soft loop pile fabric and the inner panel is composed of double layers of thermoplastic sheet material heat-sealed together to define at least one and preferably two serpentine flow passages for the circulation of thermal fluid through the blanket. The foot sections have bottom edges joined by one or more elastic webs. Hook-providing attachment patches, releasably attachable to the loop pile fabric that forms the entire outer surface of all of the sections of the blanket, detachably secure the upper edges of the foot sections together, as well as the front edges of the ankle section and the ends of the band portion of the T-shaped section, when the blanket is worn.
