Patent ID: 8764408

Claim:
A pump system, comprising: an infusion tubing for delivering a fluid; a motor driven pump in mechanical communication with the infusion tubing and configured to pump the fluid through the infusion tubing; 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 central controller in electrical communication with the motor driven pump and the at least one thermal element; and a user interface in electrical communication with the central controller, the user interface comprising a prime input and a bolus input; wherein the central controller is configured to prime the infusion tubing by causing the motor driven pump to deliver the fluid through the infusion tubing in response to selection of the prime input and then, after priming the infusion tubing, to automatically deliver the fluid through the infusion tubing at a previously selected flow rate; and wherein the central controller is configured to deliver the fluid by causing the motor driven pump to deliver a predetermined bolus volume of the fluid through the infusion tubing at a predetermined default bolus flow rate, or a user-selected bolus flow rate, in response to selection of the bolus input and then, after delivering the predetermined bolus volume, to automatically return to delivering the fluid through the infusion tubing at a previously selected flow rate or stop delivery of the fluid, according to a state of the pump prior to selection of the bolus input.
