ULTRA LOW-LEAKAGE SILICONE-BASED HEATER THERMALLY COUPLED TO A HEAT TRANSFER BODY

Abstract:

Systems and methods include a heat transfer body with opposing major surfaces formed from a thermally conductive substrate in intimate thermal interaction with an alumina exterior surface that extends across the major surfaces of the body. In an illustrative example, the heat source may be a substantially planar, silicone-based heater source (P-SBHS). The heat transfer body may be configured to thermally interact, for example, heat from a heat source proximate a first of the major surfaces to a second of the major surfaces. A temperature sensor module may be located, for example, proximate to the first major surface such that a temperature sensor thermally interacts with the first major surface. The temperature sensor module may, for example, insulate the temperature sensor from the P-SBHS. The electrical insulation provided by the alumina exterior surface may reduce electrical leakage currents induced between the P-SBHS and, for example, patient and/or operator accessible parts.
