Abstract
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.
