Abstract:
1. An intravenous administration set adjustable flow rate flow control device which includes an intravenous fluid delivery arrangement having an inlet and a plurality of spaced orifice plates, each defining an orifice configured to deliver a metered quantity of intravenous fluid, all of the orifices being simultaneously in fluid flow communication with the inlet via a single conduit, the fluid delivery arrangement including a separating element, comprising gasket of a resiliently flexible material, with the gasket carrying the orifice plates; and a passage defining member displaceably arranged relative to the delivery arrangement downstream of the orifices, the passage defining member defining a passage which is able to be brought into direct fluid flow communication with a desired number of orifices to achieve a desired flow rate through an outlet, which is in communication with the passage of the passage defining member, by adjusting the position of the passage defining member relative to the orifices of the delivery arrangement, the flow rate through the outlet being dependent on the number of orifices in direct communication with the passage of the passage defining member.
