Method and apparatus for regulating the temperature of a liquid transporting heat, and use of this method or apparatus for producing or maintaining normothermia or hyperthermia by extracorporeal circulation

摘要

The invention relates to a method and an apparatus for regulating the temperature of a liquid transporting heat, used for producing and maintaining normothermia or hyperthermia by extracorporeal circulation. The apparatus comprises a liquid tank heated by one of the two available resistors 14-15, the temperature of which is electronically regulated 12, and has various safety systems 17, 10, 12. It may be powered by an outside low-voltage source 2, and itself supply an extracorporeal circulation pump 3. Finally, it comprises various temperature controls necessary for correct running of the extracorporeal circulation 22, 23, 24, 25, 27, 28, 29, 30. As a safety measure, these controls are powered independently and in isolation by a battery 26. IMAGE
