ABSTRACT:
An air elimination system is provided for an intravenous fluid delivery system for intravenous injection of fluid into a patient. An air-detection apparatus is disposed in an intravenous fluid line. At the top end of the line is attached a chamber where air may be separated from the fluid. The separation chamber may be a drip chamber, a metering chamber or the intravenous supply. When air is detected, a valve or valves are switched, so that the intravenous fluid is prevented from flowing to the patient, and so that, when a pump is turned on, the fluid is pumped to the separation chamber. In a preferred embodiment, the volume of pump's fluid capacity is greater than the volume of the fluid capacity of the intravenous line between the pump and the separation chamber so that the pump can force air back up the intravenous line all the way to the separation chamber.
