US Classification:

604 616, 604264, 604 401

Abstract:

A tubing set for use with a blood handling system is described that decreases the priming volume and surface area of the blood handling circuit, lowering the risk of hemodilution, platelet activation, and hemolysis. The tubing set also reduces the number of manual connections required, and uses quick-disconnect couplings to facilitate connections between the various lines, and between the lines and the arterial and venous cannulae.
