ABSTRACT:
Equipment sets for the sequential administration of medical liquids wherein a primary liquid can be administered at a flow rate independent of the flow rate of a secondary liquid, and including a barrier substantially impervious to air to prevent the inadvertent administration of air when the secondary liquid is depleted. The sets of this invention provide parallel flow paths for the secondary liquid to insure that the flow of primary liquid is interrupted while the secondary liquid is flowing. A 3-way valve is provided in the first parallel branch to facilitate priming of the set.
