1. An anti-air embolism safety device adapted for placement between a central venous pressure (CVP) catheter which is attached to a patient and an external source of intravenous fluid being infused into the patient, comprising:

  • (a) a formed body adapted to operably connect the catheter and the external fluid source;

    (b) an inlet connection means within the body adapted to operably connect with said fluid source;

    (c) a fluid outlet means on the body and further comprising means for locking the outlet means to the catheter;

    (d) a first passageway within the body communicating between the inlet and the outlet means and adapted for intravenous fluid passage therethough;

    (e) a first occluder means interposed within the first passageway biased to prevent the entrainment of air therein, and of any airflow to the catheter secured to the outlet means upon the accidental cessation of fluid passage into said inlet means; and

    (f) further wherein (i) a second passageway is provided in said body connecting the inlet and outlet sections of the first passageway so as to bypass the first occluder means and (ii) having a second occluder means normally inserted into said second passageway and being associated with (iii) a linear biasing means that normally interposes the second means into said second passageway to occlude same and (iii) manually operable position adjusting means pinned to the biasing means, adapted for exerting a counterforce against the normal passageway occluding position of said second means sufficient to retract same from said second passageway.
