ABSTRACT:
An infusion pump has a base and a holder for a syringe extending along a longitudinal axis and having an axially shiftable plunger. The holder is pivotal on the base about a first axis substantially perpendicular to the longitudinal axis of the syringe. A first actuator connected between the base and the holder can oscillate the holder about the first axis relative to the base. A pusher is displaceable linearly on the base transversely of the first axis by a second actuator that can press this pusher against the plunger and thereby slide the plunger of the syringe and empty the syringe's contents. A controller is connected to the first and second actuators for moving the pusher out of engagement with the plunger during oscillation of the syringe and for operating the second actuator only when the first actuator is not oscillating the syringe to express the contents of the syringe.
