Infusion pump system and method with common line auto flush

A control system for controlling operation of an infusion pump system, the infusion pump system comprising a first reservoir configured to hold a first fluid, a second reservoir configured to hold a second fluid, a junction in fluid communication with the first reservoir and the second reservoir, a common line in fluid communication with the junction and having a terminal fluid delivery end, and an infusion pump operable to drive fluid through the common line toward the terminal fluid delivery end, the control system comprising one or more hardware processors configured to:

• receive instructions for delivery of a first fluid at a first rate followed by a second fluid at a second rate;
• automatically generate a user interface configured to receive an input for a first volume for sequential infusion, wherein first volume is configured to clear the first fluid from a common line;
• infuse a first fluid at a first rate along a first flow path;
• infuse a second fluid at the first rate along a second flow path;
• monitor a second volume of the second fluid infused at the first rate;
• determine when the monitored volume of the second fluid meets or exceeds the first volume;
• and
• change infusion of the second fluid to the second rate along the second flow path based on the determination when the monitored volume of the second fluid meets or exceeds the first volume.
