Patient warming and dvt prevention system

A patient warming and deep vein thrombosis prevention system comprising:

• a first compliant layer and a second compliant layer sealed together around an outer border to contain a warm liquid therebetween and to form a wrap configured to surround and conform to a body portion of a patient, the wrap comprising:
• a generally longitudinal central portion sized to cover a surface of the body portion;
• a plurality of flaps extending from opposite sides of the central portion, wherein one or more flaps from the opposite sides fasten to each other to surround the body portion and the flaps are openable during functional use to provide access to an underlying patient body surface;
• a continuous fluid flow path extending between the first compliant layer and the second compliant layer between a fluid inlet and a fluid outlet, said path defined by the outer border and a plurality of internal sealed connections between the first and second compliant layers;
• and
• a fluid control pump configured to direct the liquid through the fluid flow path so as simultaneously to fill the wrap and apply pressure and heat to the body portion being surrounded by the wrap.
