Abstract
Equipment sets for the sequential administration of medical liquids allow primary liquid to be administered at a flow rate independent of the flow rate of a secondary liquid. The sets include a combined air barrier and liquid sequencing device to prevent the inadvertent administration of air when secondary liquid is depleted. The device also prevents the flow of primary liquid when secondary liquid is being dispensed.
