We manufacture products to help operating room personnel keep warm. The Operationheatjacs produce heat, and are to be worn around the torso, over scrubs and under a scrub warm-up jacket or surgical gown or whatever one currently wears to keep warm. They generate heat by either using a rechargeable Li-ion battery or a transformer as the power source, or from the exothermic reaction of air-activated warmers. Choose from three models and four products designed for those who are stationary the majority of the time such as anesthesiologists and CRNAs, or for those who need to be on the move such as perioperative nurses. Your own personal wearable radiator.
