Abstract
A controller (34) is disclosed for use with a dual delivery system including a primary fluid container (12) and a secondary fluid container (14). The display (48) on the controller (34) presents a representation of the primary and secondary containers and prompts the operator to input the desired primary and secondary fluid flow rates and primary and secondary fluid volumes to be infused. During operation of the controller, a series of flow lines displays (118, 126, 144) represent motion of fluid from the container being drained to indicate to the operator which fluid is being infused. An alarm will be sounded upon the detection of an occlusion within the flow lines, the presence of air within the flow lines or an open door on the controller. During the flow from a particular container, the displays associated with the other container are deactivated to prevent confusion to the operator.
