Abstract
An external fluid warming device is described that includes a fluid warming chamber and an air separation chamber. The fluid warming chamber has a fluid inlet that communicates with a fluid pathway. The air separation chamber that communicates with the fluid pathway has a fluid outlet and a gas outlet. A heating source, such as heat plates, are disposed adjacent the fluid pathway for transferring heat to the fluid. In use, the air separation chamber is positioned above the fluid warming chamber and the heating source. The fluid inlet is connected to a source of fluid and the fluid outlet is connected to an output device, such as an ultrafiltration machine. Gas generated during warming of the fluid collects at a top of the air separation chamber and is vented through the gas outlet, whereas fluid passes through a bottom of the air separation chamber and through the fluid outlet.
