Abstract
Methods and apparatus are described for controlling the temperature and flow rate of fluids being delivered to patients. A control unit is disclosed that interfaces with specialized fluid administration set apparatus. The control unit provides power, user interface and integrated pumping and heat exchange apparatus that interfaces with a cartridge on the fluid administration set. The fluid administration set is a disposable apparatus while the control unit is a reusable device. The entire system, due to its portability and engineering features, is adapted for use either in-hospital or in the pre-hospital, emergency setting.

10. A method of fluid administration into a mammalian body comprising the steps of:
-
connecting a fluid filled reservoir to the inflow end of a length of fluid administration tubing;
providing a cartridge at a midpoint of said fluid administration tubing;
inserting said cartridge into a control unit;
inserting the outflow end of the fluid administration tubing into a vascular access site on a mammalian body, or using the outflow end for provision of fluids to a tissue site;
heating or cooling said fluid as it passes through said cartridge and;
pumping said fluid into the patient at a controlled rate;
