ABSTRACT:
A sequential medication delivery device for intravenous administration of plural medications is disclosed. A secondary medication can be administered to a patient followed by an automatic resumption of the delivery of the primary medication at a predetermined flow rate. The disclosed medication delivery device includes an internal valving system and an associated medication chamber that contains the secondary medication to be delivered. While the medication chamber contains such secondary medication, the flow of primary medication to the patient is interrupted. However, once the medication chamber has been substantially emptied the flow of primary medication to the patient is resumed automatically.
