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 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.

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).

10. An intravenous (“
- IV”
) liquid delivery system comprising;an IV pump tubing set; a pump actuator operable with the IV pump tubing set; and an air removal device located downstream of the pump actuator, the air removal device including a housing having an inlet end and an outlet end, a first potted member located adjacent the inlet end, a second potted member located adjacent the outlet end, and a plurality of air passing but liquid retaining hollow fibers extending from the first potted member to the second potted member, wherein medical fluid potentially entraining air is passed through the hollow fibers so as to provide an air path of least resistance radially out of the hollow fibers. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for an intravenous (“
- IV”
) liquid delivery system including an air removal device located downstream of a pump actuator operable with an IV pump tubing set, the method comprising;sensing whether the air removal device is present; allowing the pump actuator to operate with the IV pump tubing set if the air removal device is sensed as present, even if air is detected upstream of the air removal device; and preventing the pump actuator from operating with the IV pump tubing set if the air removal device is not sensed. - View Dependent Claims (19, 20)
