ABSTRACT:
A one way valve means for incorporation into a fluid administration set for enteral therapy which arrests retrograde movement of fluid into the set to avoid flow rate interruption or, in the event of extreme fluid back pressure, rupturing of the tubing in the set. The one way valve means is responsive to fluid back pressure and is incorporated in a male connector disposed on a distal end of the administration set tubing. As a result retrograde fluid movement caused by either irrigation or patient originated, fluid back pressure is immediately arrested before fluid enters the administration set.
