Dedicated consumable sets for syringe infusion pumps

A method of operating an infusion pump to reduce post-occlusion bolus, the infusion pump configured to operate with a syringe and an infusion set including a housing, a valve configured to block or regulate a flow of liquid through the set, and a pressure sensor for measuring pressure inside the infusion set, the method comprising:

• pressurizing the syringe and the infusion set to begin operation in a steady state delivery mode;
• sensing a pressure increase by the pressure sensor indicative of an occlusion;
• closing the valve in response to the occlusion;
• reversing operation direction of the infusion pump to decrease the force applied to the syringe to reduce any accumulated bolus;
• and
• opening the valve after clearing the occlusion such that operation of the infusion pump in steady state delivery mode can resume.

A system for delivering infusate from a syringe, the system comprising:

• a syringe pump including a housing, a syringe drive assembly, and a syringe receptacle comprising a cavity extending across a front of the housing;
• and
• an infusion set including a valve operable to block or regulate a flow of infusate through the set, and a pressure sensor for measuring pressure inside the infusion set,
• wherein the valve is configured to automatically actuate between an open position and a closed position, or to proportionally adjust restriction, in response to an external event.
