Patent ID: 8360737

Claim:
A pump system comprising: an infusion tubing; a pumping mechanism; a motor drive assembly in mechanical communication with said pumping mechanism; a user input control; an electronic controller in electrical communication with and at least partially controlling said motor drive assembly; and a disposable heat exchanger cartridge removably coupled under pressure to at least one of a heating element or a cooling element; wherein: said electronic controller comprises a digital signal processing controller in electrical communication with said motor drive assembly; said digital signal processing controller is configured to receive a signal from said user input control and to cause power to be supplied to said motor drive assembly in response at least partially to said signal from said user input control; said disposal heat exchanger cartridge comprises a first half constructed from thermally conductive material correspondingly mating with said heating or cooling element; a second half constructed from thermally conductive material opposite said first half; and an internal heat exchange zone existing between said first half and said second half, wherein fluid flows therethrough; said heating or cooling element further comprises at least one thermoelectric heat pump and selectable creates at least one heat point or at least cooling point on the heating and cooling element; said disposal heat exchanger cartridge is configured to receive and pass therethrough fluid from said infusion tubing as a result of the operation of said pumping mechanism, and said pump system selectably delivers fluid at rates from about 1 milliliter per hour to at least about 3000 milliliters per minute.
