Abstract:
Provided herein is a method and apparatus for venting of intravenous tubing to remove air bubbles, and more particularly, to a venting valve that allows air bubbles to escape along a venting path while not permitting fluid passage through the venting path. An example air extraction device may include: a chamber; a fluid inlet to convey fluid from intravenous tubing into the chamber; a fluid outlet to convey fluid from the chamber to intravenous tubing for supplying to a patient; a top portion of the chamber; a branch tube extending from the top portion of the chamber, where the branch tube receives air from the fluid in the chamber; and a ball received within the chamber, where the ball is configured to rise with an influx of fluid to the chamber from the fluid inlet and to seal off the branch tube from the chamber in response to the fluid level rising to the top portion of the chamber.
