Abstract:
1. Apparatus for warming infusate or intravenous fluids for use by a patient, comprising: a radio frequency (RF) generator adapted to output a RF energy; a fluid store; a body having an enclosed chamber extending along a longitudinal axis with an inlet and an outlet, a fluid from said fluid store for treatment of a patient passing into said chamber through the inlet and out of said chamber through the outlet, at least one pair of electrodes spaced apart substantially in parallel along the longitudinal axis within said chamber electrically connected to said generator, said electrodes selectively powered by RF energy from said generator for effecting an electric field between said electrodes to cause direct heating of the fluid entering into said chamber through the inlet and passing between said spaced apart electrodes along the length of said chamber before exiting through the outlet; and a temperature regulating system communicatively connected to said body for sensing the temperature of the fluid in said chamber and for controlling the RF energy supplied to said electrodes to maintain the fluid in said chamber at a desired temperature.
