INTRAVENOUS PUMPING AIR MANAGEMENT SYSTEMS AND METHODS

摘要

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).

1. An intravenous (“IV”) liquid delivery system comprising:
an IV pump tubing set; a pump actuator operable with the IV pump tubing set; an air removal device located downstream of the pump actuator, the air removal device including an air passing but liquid retaining filter and a liquid passing but air retaining filter; an indicating device that indicates that the air removal device is present; and a control unit operable with the indicating device, the control unit configured so that when the air removal device is indicated as being present, the pump actuator is allowed to operate the IV pump tubing set even if air is detected upstream of the air removal device.
