Abstract
Abstract The disclosure describes an administration set for providing a flow of fluid from a fluid container to a patient and comprising a section of tubing for channeling the fluid to the patient, an inlet spike attached to the tubing and connectable to the container for establishing a flow of fluid into the tubing, a connector attached to the tubing downstream from the inlet spike for sealingly receiving an inlet spike from a second administration set, and an arrangement operatively associated with the tubing and the connector for directing a flow of fluid into the inlet spike of the second administration set.
