The present invention relates to a system for increasing the temperature of a fluid being infused into a patient's body while the infusion is taking place. The present invention also provides for improved monitoring of air in the infusion system such to prevent the introduction of air into the patient's body receiving the fluid infusion. The present invention also provides for a system pump which provides a variable flow rate that serves a vast amount of infusion needs and purposes. A disposable cartridge in accordance with the present invention will allow for the efficient transfer of heat energy to the fluid being infused into the patient's body. The cartridge will further ensure that deleterious amounts of air will not be introduced into the patient's body.

Fluid heat exchanger

A pump system selectably controls the temperature, flow rate, flow volume, and flow pressure of a fluid being infused into a patient's body. The pump system includes a cartridge and components that removably connect with a pump housing and corresponding components, providing simple attachment of the cartridge to the pump housing. The pump housing includes a pressure sensor, a bubble detector, and a temperature sensor on a first side of the pump housing, and an engaging actuator and a central controller. The cartridge includes on a first side a heat exchanger, a pressure receptor correspondingly aligned with the pressure sensor, and a detector interface correspondingly aligned with the bubble detector and temperature sensor. Upon aligning the cartridge with the pump housing and actuating the engaging actuator, the pressure receptor communicates with the pressure sensor and the detector interface aligns with the bubble detector and temperature sensor.
