1. An infusion pump, comprising:

  • a specially programmed microprocessor;

    a flow sensor for measuring flow from a source of fluid through an output tubing;

    a pumping section including a plurality of fingers in operational relationship to the output tubing, an outlet valve associated with the output tubing, and a first actuator, controlled by said microprocessor and operating both said outlet valve and said plurality of fingers to displace fluid through the output tubing;

    an inlet valve disposed between the pumping section and the source of fluid operating separately from said first actuator and associated said outlet valve and said plurality of fingers; and

    a second actuator, controlled by said microprocessor and operating said inlet valve, wherein for detection, by the flow sensor, of flow above a predetermined level stored in a memory of said microprocessor, the microprocessor is configured for one of;

    closing the outlet valve independently of the inlet valve using the first actuator and closing the inlet valve independently of the outlet valve using the second actuator.
