US Patent 9498586 Infusion pump system and related methods

An infusion pump system including an infusion tubing for delivering a fluid, a heat exchanger cartridge in fluid communication with the infusion tubing and removably coupled to at least one thermal element for heating or cooling the fluid, a motor driven pump in mechanical communication with the infusion tubing and configured to pump the fluid through the infusion tubing and the heat exchanger cartridge, and a central controller in electrical communication with the motor driven pump and the at least one thermal element. The central controller is configured to selectively deliver the fluid to a patient without heating or cooling the fluid by causing the motor driven pump to pump the fluid through the infusion tubing and the heat exchanger cartridge while the thermal element is off.
