ABSTRACT:
A bubble free, self-priming IV set for use in the administration of liquids that includes a drip chamber comprising a chamber inlet and a chamber outlet, a bubble isolation device disposed within the drip chamber that prevents air bubbles from exiting the chamber outlet, a tube having an inlet end coupled to the chamber outlet of the drip chamber and an outlet end, and an end plug that includes an air vent. The end plug may be coupled to the outlet end of the tube and is a flow restrictor so that when a liquid is moving through the tube, the velocity of the liquid flow is controlled such that the front of the liquid does not trap bubbles in the tube.
