Infusion pump with independently controllable valves and low power operation and methods thereof

摘要

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.

主权项

1. An infusion pump for controlling a flow condition of a source of fluid and delivered to a user through an output tubing, the pump comprising:
a computer processor; a first actuator configured for displacing at least one finger for compressing a first portion of the output tubing to deliver the source of fluid to the user; a second actuator configured for selectively operating an inlet valve of the infusion pump to control the flow condition of the source of fluid to the first portion of the output tubing; and an outlet valve is disposed downstream of the first portion of the output tubing, and the output tubing includes a second portion between the inlet and outlet valves, said outlet valve being controlled by said first actuator, wherein, using the processor, the first actuator controls the displacement of the at least one finger and the operation of said outlet valve independently from the inlet valve, and the second actuator controls the operation of the inlet valve independently from the at least one finger.
