1. A system, comprising:
a barrel;
a plunger assembly disposed at least partially within the barrel, at least a portion of the plunger assembly being moveable within the barrel between an inserted position and a withdrawn position, the plunger assembly comprising a plunger body having a shaft;
an acoustic volume sensor downstream from the plunger assembly;
a shape memory actuator positioned longitudinally within the plunger body, having a first end fixed directly to the plunger assembly, and being configured to displace the at least a portion of the plunger assembly from the withdrawn position to the inserted position during application of current to the shape memory actuator; a bias member surrounding a segment of the plunger assembly and not surrounding the barrel, the bias member biasing the at least a portion of the plunger assembly to the withdrawn position;
a reservoir for holding an infusion medium, the reservoir having a port for receiving the infusion medium; and
a fluid line extending from the reservoir to an outlet, the fluid line comprising an upstream valve and a downstream valve respectively disposed upstream and downstream of a portion of the fluid line in line with the barrel,
wherein the acoustic volume sensor is downstream from the downstream valve and is configured to measure a volume of the infusion medium forced through the fluid line via displacement of the at least a portion of the plunger assembly from the withdrawn position to the inserted position.
