1. A fluid warming device comprising:
- a housing comprising a main body and a pair of covers, the covers axially slidable on the main body, and a heat exchange body receiving compartment in the main body;
a heater assembly disposed within the main body; and
a heat exchange body removably disposable in the compartment of the main body in contact with a heat conducting surface of the heater assembly, the heat exchange body comprising a fluid input port, a fluid output port, and a fluid flow path from the fluid input port to the fluid output port, wherein the fluid input port is connectable to a first fluid line to receive a fluid and the fluid output port is connectable to a second fluid line to deliver the fluid;
wherein the covers are slidable axially on the main body to a closed position in which the covers press the heat exchanger into heat exchange communication with the heater assembly.

Abstract
A fluid warming device includes axially or longitudinally slidable covers that retain a removable heat exchange body in a housing in heat exchange communication with a heater assembly while allowing flow through the heat exchange body to be observed. In another aspect, a fluid warming system increases or decreases power to a heater assembly to adjust the fluid temperature to ensure that the fluid is at an appropriate temperature when it reaches the patient.

16. A fluid warming device comprising:
-
a housing comprising a main body and having a heat exchange body receiving compartment and a pair of covers axially slidable on the main body; a heater assembly disposed within the main body; and a heat exchange body removably disposable in the compartment of the main body in contact with a heat conducting surface of the heater assembly and configured to be coupled to intravenous tubing via an input port and an output port of the heat exchange body; wherein the covers press the heat exchanger into heat exchange communication with the heater assembly when in a closed position.
