ABSTRACT:
The intravenous (I.V.) system provides for successive administration to a patient of two or more solutions but at different flow rates. Such system includes a primary or first intravenous set including tubing which at one end thereof enters a container having a first solution at a predetermined level and which extends from that point towards the patient. The tubing of the primary set includes a check valve above the connector site. A secondary set may be temporarily or permanently connected to the connector site and includes tubing attached to a second container having a second solution at a level above the level of the first fluid. Adjustable and independent flow control devices are provided in the tubing of the primary set, one flow control device being located downstream of the connector site for controlling the flow of solution from the second container and the other flow control device being located upstream of the connector site for automatically turning on and off the first solution at its own, individually set, flow rate, generally after the termination of the flow of the solution from the second container.
