Cold therapy is an established practice used in the medical profession to treat certain limb injuries, such as sprained or strained arm or leg muscles or injuries to joints. Generally, these types of injuries should be chilled to slow blood flow, which reduces swelling, pain, and further damage. Cold therapy is also an established practice used to treat migraine and other types of headaches. A typical course of cold therapy treatment is to apply ice for a specified period to the injured region of a limb, the neck, face, or head. Alternatively, a pack or bag containing a chemical agent that reacts (endothermically) to produce cold may be applied to the injured region, the neck, face, or head. The cold pack (11) has a first compartment (21'), a second compartment (21' ', 21' ' '), and a connection (23', 23'') between the first and second compartment, the connection adapted to pass the endothermic solution between the first hand second compartment. ® KIPO & WIPO 2009
