Programmable infusion pump
First Claim
1. An infusion pump system, comprising:
- disposable tubing means having an elastic segment and one-way check valves at each end of said segment, said valves oriented in a common direction thereby defining an inlet valve and an outlet valve, and said inlet valve has a lower cracking pressure than said outlet valve for conveying intravenous fluid from a source to a patient;
a compact, portable housing having an open receptacle for removably receiving said elastic segment and said check valves of the disposable tubing means;
reciprocating ram means mounted in the housing for periodically engaging and compressing the segment of the disposable tubing means for pumping fluid therethrough;
motor means mounted in the housing for driving the ram means upon energization thereof; and
control means mounted in the housing for energizing the motor means so that the fluid is pumped through the disposable means in accordance with pre-selected delivery rate parameters.
