ABSTRACT:
Anticoagulant is added to blood being aspirated through a hand-held wand having a venturi throat. The anticoagulant flows into the wand from a generally closed anticoagulant reservoir higher than the wand as replacement air flows into the anticoagulant air reservoir. This air inflow is controlled by a regulator fixed on the wand and in accordance with the amount of aspirated blood flowing in through the venturi throat.
