The apparatus includes a tubing set and a laser drilled orifice flow restrictor, formed in a body, and in fluid communication therewith, for use with an associated fluid supply container. The system provides a controlled, predetermined flow rate of solution to the patient which is independent of, and relatively constant over minor variations in solution supply pressure and viscosity.
