Abstract

A multi-zone blanket includes a body including first heat zones juxtaposed side-by-side and symmetrically aligned within a body cavity. A first primary heating element passes through each of the first heat zones. A first external controller has an AC/DC transformer electrically coupled thereto. The first controller is electrically coupled and removably attached to the first primary heating element. The transformer is removably coupled to an external power supply source which provides a high voltage input to the transformer. The transformer converts the high voltage input to a low voltage input. The first controller includes a mechanism for providing output control signals to the first heat zones such that each first heat zone can simultaneously and independently generate a selected quantity of heat.
