ABSTRACT:
The fluid delivery system includes a control console adapted to control delivery of fluid to a patient and a pump cassette disposed in a pump cassette socket in the control console and operatively controlled by the control console. The pump cassette includes a pump housing formed by opposing housing members that cooperatively define a pump chamber. A pair of meshed gears is disposed in the pump chamber and separate the pump chamber into a fluid inlet area and a fluid outlet area accessible through respective inlet and outlet ports in the pump housing. The gears are adapted to pressurize fluid for delivery to the patient. Other features of the system include a fluid heater upstream of the pump cassette, air detectors associated with the inlet and outlet ports of the pump cassette, and a sensor to read an encoding device associated with the pump cassette.
