Abstract
A heat exchange system selectably controls the temperature of a fluid being delivered to a patient's body by a pump device. The heat exchange system includes a thermal element and a heat exchanger that is removably coupled under pressure to the thermal element. The heat exchanger includes a first half made from thermally conductive material that correspondingly mates with the thermal element, a second half made from thermally conductive material opposite the first half, and an internal heat exchange zone existing between the first half and the second half, wherein fluid flows therethrough. The thermal element of the heat exchange system may controllably and safely warm and/or cool the fluid prior to delivery.
