Abstract (en)
[origin: WO8001756A1] Gravitational flow systems and equipment sets for the sequential administration of medical liquids wherein a primary source (11) can be administered at a flow rate independent of the flow rate of a secondary source (13) and including a barrier (47) substantially impervious to air to prevent the inadvertent administration of air when the secondary source (13) is depleted. The air barrier may consist of either a hydrophilic membrane (45) or mechanical float valve (65) or a diaphragm operated barrier member (241).
