Never be cold in the OR again with OPERATIONHEATJAC, a heated belt that fits around the torso and serves as a personal radiator. OPERATIONHEATJAC goes over the scrubs and under a warm-up jacket or surgical gown. Heat is delivered by electrical heating pads or air-activated warmers. The pads can be powered by a rechargeable battery for mobility or a transformer for those in a stationary position. Choose from four models and three sizes.
