Methods and systems for verifying the contents of a syringe used for medical fluid delivery

A method of verifying a content of a syringe in a fluid delivery system, comprising:

• dispensing a fluid from the syringe;
• obtaining, using one or more sensors, one or more measurements of a force required to dispense the fluid from the syringe;
• and
• determining, from the one or more measurements of the force required to dispense the fluid from the syringe, whether the fluid is a correct fluid.

A fluid delivery system, comprising:

• a fluid path set, comprising:
• a syringe;
• a purge tube;
• a connector tube creating a fluid path between the syringe and the purge tube;
• and
• a flow restrictor positioned in the purge tube and adapted to restrict fluid flow through the purge tube;
• a fluid injector for delivering a fluid through the fluid path set;
• one or more sensors adapted to measure a force required to deliver the fluid through the fluid path set;
• a processor in communication with the one or more sensors;
• and
• a non-transitory, computer-readable storage medium in operable communication with the processor,
• wherein the computer-readable storage medium contains one or more programming instructions that, when executed, cause the processor to receive one or more measurements of the force required to deliver the fluid through the fluid path set from the one or more sensors and detect an increase in the force required to deliver the fluid through the fluid path set.
