AN IMPROVED AIR WARMING SYSTEM FOR PROVIDING A CONTROLLED TEMPERATURE OF AIR TO AN AIR BLANKET

摘要

A fluid blanket warming system for a patient includes a thermal blanket unit for receiving heated gas through a coupling port. A portable heat source includes a heater unit and a blower unit that are controlled by a control circuit for providing a desired output to temperature to a patient. A flexible conduit delivers the heated gas from the heat source to the thermal blanket. A temperature sensor unit can be mounted adjacent the thermal blanket unit and in contact with the gas received from the heater unit to provide a temperature signal representative of the heated gas. The temperature sensor unit can be mounted directly on the thermal blanket, on the coupler of the flexible conduit, or on a modular coupler to provide a temperature signal to the control circuit.
