A heat exchanger has a multi-lumen tubing having one end connected to a supply fitting and another end connected to a return fitting. The tubing has a central lumen, a middle lumen that surrounds the central lumen and an outer lumen that surrounds the middle lumen. The supply fitting has an inlet, an outlet and a proximal port wherethrough an infusate is input to the heat exchanger. The supply fitting is configured such that its inlet is connected to the central lumen, its outlet connected to the outer lumen, and its proximal port connected to the middle lumen of the tubing. The return fitting is configured to establish a through passage between the central lumen and the outer lumen of the tubing so that a heating fluid fed through the supply fitting to the central lumen is returned to the supply fitting by way of the outer lumen. The return fitting further has a distal port configured to connect to the central lumen of the tubing, so that the infusate fed to the proximal port of the supply fitting may be output from the distal port of the return fitting, after passing through the central lumen of the tubing. As the infusate traverses along the heat exchanger, it is heated by the heating fluid that flows along the central lumen, and also by the rerouted heating fluid that flows along the outer lumen of the tubing. The heat exchanger is fluidly coupled to a heater by its inlet and outlet so that the temperature of the heating fluid for warming the infusate is maintained at a predetermined temperature.

Léchangeur de chaleur selon linvention comprend un tubage à lumières multiples dont une extrémité est reliée à un raccord dalimentation et une autre extrémité est reliée à un raccord de retour. Le tubage comprend une lumière centrale, une lumière intermédiaire qui entoure la lumière centrale et une lumière externe qui entoure la lumière intermédiaire. Le raccord dalimentation comprend un orifice dentrée, un orifice de sortie et un orifice proximal à travers lequel un fluide infusé est introduit dans léchangeur de chaleur. Le raccord dalimentation est configuré de manière à ce que son orifice dentrée soit raccordé à la lumière centrale, son orifice de sortie à la lumière externe et son orifice proximal à la lumière intermédiaire du tubage. Le raccord de retour est configuré pour établir un passage traversant entre la lumière centrale et la lumière externe du tubage. Ainsi, un fluide chauffant acheminé vers la lumière centrale à travers le raccord dalimentation est réacheminé vers le raccord dalimentation au moyen de la lumière externe. Le raccord de retour comprend en outre un orifice distal configuré pour être relié à la lumière centrale du tubage, de manière à ce que le fluide infusé acheminé vers lorifice proximal du raccord dalimentation puisse être évacué par lorifice distal du raccord de retour après avoir traversé la lumière centrale du tubage. A mesure que le fluide infusé est acheminé le long de la lumière centrale, il est chauffé par le fluide chauffant qui sécoule le long de la lumière externe, et également par le fluide chauffant réacheminé qui sécoule le long de la lumière externe du tubage. Léchangeur de chaleur est raccordé en communication fluidique à un appareil chauffant par son orifice dentrée et de sortie pour chauffer le fluide infusé et le maintenir à une température prédéterminée.
