Warming methods and apparatus

摘要

Apparatus and method for raising or maintaining the core temperature of a mammal during surgery is disclosed. The apparatus comprises a infrared radiant element with a double reflector design to provide a very narrow beam of radiation. In this fashion the apparatus is able to direct radiant energy at the mammal's skin in regions with a high concentration of Arteriovenous Anastomoses. The apparatus also includes a skin temperature sensor to allow closed loop control of the heat energy supplied to the mammal. The complete apparatus can be located in an unobtrusive position such that it does not interfere with the surgical team.
