Abstract
A one-piece unitary occluder is disclosed which is utilized with a fluid administration set to occlude a portion of a tube assembly which is interconnected between a source of fluid and a patient. The one-piece unitary occluder has a body with a pair of openings which are diametrically aligned with an aperture to allow fluid flow therethrough; however, once activated, the openings are misaligned relative to the aperture to occlude a portion of the tubing to prevent fluid free-flow if the tube assembly becomes disassociated from the pump.
