ABSTRACT:
A closed-system, combination infusion and flush set which enables safe administration of both medicaments and flush solutions to a patient with great accuracy using conventional large volume parenteral bags. The administration set comprises a specially designed rotatable valve member for controlling fluid flow through the set and includes a stop post which positively blocks rotation of the valve member to a position that permits the flow of flush solution toward the patient.
