Intravenous pumping air management systems and methods
First Claim
1. An intravenous (“
- IV”
) liquid delivery system comprising;
an IV pump tubing set;
a pump actuator operable with the IV pump tubing set;
an upstream valve actuator operable with the IV pump tubing set upstream of the pump actuator;
a downstream valve actuator operable with the IV pump tubing set downstream of the pump actuator;
an air purge valve actuator operable with the IV pump tubing set downstream of the downstream valve actuator; and
an air removal device located between the downstream valve actuator and the air purge valve actuator;
at least one air detector for detecting air in the IV pump tubing set; and
the system configured, upon receipt of a signal indicating air from the at least one air detector, to (i) close the air purge valve actuator, and (ii) force air in the IV pump tubing set to be purged through the air removal device.

Abstract
An intravenous (“IV”) liquid delivery system includes: an IV pump tubing set; a shuttle pump or membrane pump actuator operable with the IV pump tubing set; upstream and downstream valve actuators operable with the IV pump tubing set; the IV pump tubing set including an air removal device; an air detector configured to sense air in the IV pump tubing set; a control unit configured and arranged to (i) open the upstream valve actuator and close the downstream valve actuator to allow the pump actuator to draw liquid into a pump actuation portion of the IV pump tubing set, and (ii) close the upstream valve actuator and open the downstream valve actuator to allow the pump actuator to push liquid out of the pump actuation portion, the system configured to attempt to remove the air via the air removal device while operating the upstream and downstream valve actuators according to (i) and (ii).
