Abstract
Infusate warming apparatus comprises a housing defining an internal cavity. A lossy asymmetric transmission line is situated in the housing which transmission line includes an elongated electrical conductor having opposite ends and a conduit for conducting infusate which is highly absorptive to electromagnetic energy of a first frequency through the housing in close proximity to the conductor. A connector extends into the housing for coupling an external electromagnetic signal of the first frequency to one end of the conductor so as to subject the infusate to an energy field which heats the infusate. A temperature sensor for sensing the infusate temperature and controlling the signal to maintain a constant infusate delivering temperature is also disclosed.
