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 (5) is disposed in an intravenous fluid line (3). A return line (8) is attached to a point in the line (3) below the air-detection apparatus (5). The other end of the return line (8) is attached to a chamber (1, 2, 12) where air may be separated from the fluid. The separation chamber may be a drip chamber (12), a metering chamber (2) or the intravenous supply (1). When air is detected, a valve (11) or valves (7, 9) are switched, so that the intravenous fluid is prevented from flowing to the patient, and so that, when a pump (4) is turned on, the fluid is pumped through the return line (8) to the separation chamber (1, 2, 12).

Abstract: A medical pump apparatus including an internally sterile pumping chamber having a flexible diaphragm forming a wall portion and a drive rod extending through the diaphragm in a rotating vane disposed with in the pumping chamber. A motor rotates a revolving hook which engages the drive rod to drive the vane within the pumping unit. The pumping chamber is isolated from the motor by the fluidtight attachment of the drive rod through the flexible diaphragm. Fluid is pumped into the inlet of pumping chamber through the hollow shaft of the vane and out through a fluid conduit of the vane, subsequently out th e outlet of the pumping chamber.

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 5 is disposed in an intravenous fluid line 3. At the top end of the line 3 is attached a chamber 1, 2, 12 where air may be separated from the fluid. The separation chamber may be a drip chamber 12, a metering chamber 2 or the intravenous supply 1. When air is detected, a valve 11 or valves 7, 9 are switched, so that the intravenous fluid is prevented from flowing to the patient, and so that, when a pump 4 is turned on, the fluid is pumped to the separation chamber 1, 2, 12. In a preferred embodiment, the volume of pump's fluid capacity is greater than the volume of the fluid capacity of the intravenous line 31 between the pump 4 and the separation chamber 1, 2, 12, so that the pump can force air back up the intravenous line all the way to the separation chamber.
