Abstract
An infusion pump, including: a specially programmed microprocessor; a drip chamber for connection to a source of fluid and to an output tubing; a pumping section including a plurality of fingers and a first actuator, controllable using the microprocessor, for sequentially displacing the plurality of finger to compress a first portion of the output tubing to displace fluid from the drip chamber through the output tubing; an inlet valve disposed between the drip chamber and the pumping section and arranged to compress the output tubing to restrict or block flow through the output tubing; and a second actuator, controllable using the microprocessor, for opening or closing the inlet valve independent of the displacement of the plurality of fingers; or for operating the inlet valve to control a rate of flow of fluid from the drip chamber to the portion of the output tubing.
