Abstract
An apparatus and method are disclosed for compounding of parenteral admixture solutions, and recirculation with the admixture solution being formed. The apparatus includes a multiple pump cassette configured for operative association with a pump driver, whereby one or more selected source solutions are delivered through a pump cassette to an associated admixture container. After pumping of each source solution, the present method contemplates that the admixture being formed is recirculated through the pump cassettes thereby diluting any source solution in the cassettes and associated tubing. In this manner, the possible mixture of incompatible source solutions, resulting in formation of precipitate, is desirably avoided.
