An intravenous drug infusion apparatus for controlling the delivery of a drug includes an in-line mixing vessel with tubular needle-like inlets which produce turbulent mixing of a drug solution contained in the vessel with an aqueous carrier. An admixed solution is discharged from the mixing vessel which provides intravenous infusion of a drug at progressively decreasing concentrations.

An intravenous drug infusion apparatus for controlling the delivery of a drug, comprising a container with an intravenously administrable aqueous carrier therein for discharge through an outlet thereof, a mixing vessel providing a defined interior volume for containing a solution of the drug to be infused, said defined volume providing upper and lower portions in spaced apart relation, a hollow inlet needle having an inner end extending into and terminating in said defined volume lower portion, conduit means connected to the outer end of said inlet needle providing communication between said inlet needle and said container outlet for transfer of the aqueous carrier into said mixing vessel, a hollow outlet needle having an inner end extending into and communicating with said defined volume upper portion, and delivery conduit means connected to the outer end of said outlet needle for infusion of said drug, said inlet and outlet needles being dimensioned and arranged to provide a turbulent mixing of the drug within said vessel with the incoming liquid so that admixed liquid is discharged through the outlet needle to the delivery conduit means.
