Abstract
The blood-air separator is for use in the extracorporeal blood bypass during cardio-pulmonary surgery. Air bubbles are separated from the recirculating blood stream by centrifugal force and buoyancy after the stream has left the oxygenator and before it returns to the patient. Separation is accomplished by imparting circular motion to the bloodstream within the separator at a point where air bubbles can move upward and inward, and blood liquid outward and downward. Curved vanes in the blood flow stream cause the circular blood motion.
