1. An air extraction device for removing air from intra-venous (IV) tubing, the device comprising:
a chamber;
a fluid inlet tube to convey fluid from intravenous tubing into the chamber;
a fluid outlet tube to convey fluid from the chamber to intravenous tubing for supplying to a patient; wherein the fluid inlet tube extends further into the chamber than the fluid outlet tube;
a top portion of the chamber;
a branch tube extending from the top portion of the chamber, wherein the branch tube receives air from the fluid in the chamber; and
a ball received within the chamber, wherein the ball is configured to rise with an influx of fluid to the chamber from the fluid inlet tube and to seal off the branch tube from the chamber in response to a level of the fluid level rising to the top portion of the chamber, wherein the ball within the chamber functions as a check valve to prevent fluid flow through the branch tube and to allow air to flow through the branch tube.
