Abstract
An electric warming blanket includes a flexible heater that may be enclosed within a flexible shell, which is, preferably, water resistant and may extend beyond lateral edges of the heater to support stiffening members. A layer of non-conductive flexible porous material may be bonded to one or both sides of the heater. When the heater is enclosed in the shell, a layer of thermal insulation may be disposed between one side of the heater and the shell. A temperature sensor may be coupled to the heater at a location where the heater will be in conductive contact with a body when the blanket is draped thereover, and at least one super-over temperature sensor may also be coupled to the heater; the at least one super over-temperature sensor is adapted to interrupt a supply of power to the heater.
