ABSTRACT:
A nonvented gravity fed exponential mixing and delivery system and apparatus for the administration of a drug in a precalculated manner to give constant therapeutic blood plasma levels in the recipient, (patient), which provides an inexpensive, quick and simple exponential mixing procedure to deliver an infusion containing exponentially decreasing concentrations of a drug, which the exponential mixing of a dilute solution of the drug or isotonic solution which flows by gravity from a conventional IV container, through a coupling means, into a vertically aligned nonvented nondeformable mixing chamber, filled to capacity with a concentrated solution of said drug, said mixing container being provided with a verticle inlet conduit means and a vertical outlet conduit means at opposing ends, each conduit means extending into said mixing container at a height to provide a sufficient height differential to induce exponential mixing of the solutions, to effect an exponentially decreasing concentration of said drug during a constant infusion rate, flowing through said outlet conduit and into a conventional non-vented administration apparatus.
