Abstract

A high speed bulk compounder system for filling upper and lower chambers of dual chamber TPN bags with fluid from source containers includes a controller for controlling the operation of peristaltic pump stations, each station being associated with one of the source containers. The controller activates the peristaltic pumps sequentially to draw fluids from certain ones of the source container so that the fluids flow through a common manifold and a lower chamber fill tubing into the lower chamber of the dual chamber bag. Once the lower chamber has been filled, another pump station is activated so that fluid is drawn from another of the source containers and flows through an upper chamber connector, through an upper chamber fill tubing and into the upper chamber of the dual chamber bag.
