摘要：
A syringe for performing a medical procedure includes a pressure sensor, a volume sensor, and a compensation circuit. The volume sensor measures a volume of a flowable material that is dispensed from the syringe, the pressure sensor measures a pressure being applied to the flowable material, and the compensation circuit calculates a delivered volume of the flowable material by accounting for system compliance (expansion) as the pressure is increased. By compensating for system compliance in this manner, a syringe can be used in high pressure procedures while still providing accurately controllable material delivery.
