Patent ID: 7319207

Claim:
A personnel heating apparatus comprising: a portable assembly including a blanket portion and a control apparatus; said blanket portion having an outer blanket side and an inner blanket side and including pliable cloth-like layers, said layers cooperatively provided with insulation, heat reflection and heat conducting properties inducing downwardly and inwardly directed heat conveyance to a patient with the blanket portion draped over the top and along the sides of a torso and limbs of the patient in a lying down position; an electrically actuated heating circuit provided in the pliable blanket portion among the layers and responsive to direct current electrical input for generating heat; said control apparatus including a portable carrier, an electrical control circuitry contained in the carrier, and a direct current emitting battery contained in the carrier and connected to the control circuitry and providing direct current electrical power to the control circuitry, a conductor and connectors connecting the blanket portion to the control circuitry, and said control apparatus including a core temperature sensor for sensing the core temperature of said personnel and thereby enabling such personnel's core temperature to be set, maintained and adjusted, said control apparatus including controls controlling emission and adjusting the cyclic or irregular waveform of direct current electrical power to the blanket portion; a transformer in said carrier for converting alternating current to direct current, said direct current from said transformer electrically connected to said electrical control circuitry for alternately providing direct current power to said circuitry and to said blanket portion, an alternating current input connector provided for said transformer and connectable to an alternating current plug-in, and a switch operative to connect the battery to the control circuitry when alternating current is not available to the transformer and to connect the transformer to the control circuitry when alternating current is available to the transformer; and said portable assembly including blanket portion and control apparatus having core temperature sensing, configured to provide continuing controlled heating of a patient being transported through sequential stages of medical care treatment.
