Apparatus for the prevention of retrograde movement of fluids during the use of air eliminating filters in intravenous therapy

摘要

An apparatus is provided for preventing the retrograde movement of a prescribed fluid away from a patient during use of an air eliminating filter in intravenous therapy. Such retrograde fluid movement is prevented by employing at least one vented valve assembly to prevent the displacement of air into a proximal chamber of an air eliminating filter.
