<p>A heat exchanger useful for supplying infusates over substantial distances uses an extrusion which provides a central tube for carrying an infusate and two outer channels for carrying a heat exchange fluid. A first of the channels carries the heat exchange fluid from an inlet end to an opposite end and the other of the channels returns the heat exchange fluid to the inlet end. An end cap at the inlet end is easily connected to a source of heat exchange fluid and communicates with the channels. An end cap at the opposite end receives the heat exchange fluid from the first channel and redirects it to the second channel. Both of the end caps have connectors for facilitating connection with lines from a source of infusate and a patient.</p> |
