ABSTRACT:
A phlebotomy needle assembly is provided which permits an anticoagulant to be mixed with whole blood immediately adjacent the cannula through which the whole blood is drawn, to prevent coagulation. A blood-anticoagulant mixing device has a blood inlet for coupling to the cannula, an anticoagulant solution inlet for coupling to a source of anticoagulant and a blood-anticoagulant mixture outlet for coupling to outlet tubing. The blood inlet and the anticoagulant inlet are generally coaxial and the mixture outlet is axially offset with respect to the inlets. The blood inlet defines a mixing chamber and a passage communicates with the mixing chamber and the mixing outlet for providing an outlet flow path through the mixing device for the blood-anticoagulant mixture.
