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 equipment sets of this invention have a primary tube valve controlled by pilot liquid diverted from the secondary liquid flow path.
