Abstract
An intravenous pump system includes an intravenous pump having an air bubble detector, a separate air trap module and a patient line. The air trap module is connectable to a set interface upon which the pump can operate. The air trap module includes an air chamber capable of receiving fluids and air, a plurality of valves controlling the flow of the fluids and air, and an air vent. The patient line is connectable to the air trap module and to a patient. The air trap module includes an actuator to control the state of the valves to enable, at least during a venting mode, the pump to push air out of the air chamber via the vent without disconnecting the patient from the patient line.
