Abstract: 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.

Abstract: The present invention discloses a portable intravenous fluid heating system comprising (a) a metallic heated conduit for warming IV fluids passed therethrough at a continuously regulated normal body temperature and transporting said IV fluids; and, (b) a controller unit including a power source operative to apply an electric potential across said conduit. The conduit comprises a wall made of a metallic material capable of producing resistance heat by the passage of electric current, such that said IV fluid is heated by the contact with said wall.
