A device (100) for heating a flow of liquid from an initial temperature to a desired temperature for intravenous delivery includes an elongated conduit (120) formed from metallic material having an inlet (102) for receiving the flow of liquid at the initial temperature and an outlet (104) for delivering the flow of liquid at the desired temperature. A temperature sensing arrangement (160. 162, 224) is deployed to generate an output indicating the temperature of the liquid at a number of locations along the conduit (120). A controller (140) generates electrical current flowing within at least one length of the wall of the conduit, thereby generating heat within the wall so as to heat the flow of liquid to reach the desired temperature at the outlet. |
