ABSTRACT:
A plastic blood chamber comprises a chamber-defining wall having a first blood inlet port adjacent to the end of the chamber and a blood outlet port adjacent typically the opposed end of the chamber. The inlet port is positioned in separate, lateral relation with the chamber, and has a conduit extending longitudinally of the chamber from the inlet port toward a central chamber portion in such separate, lateral relation to the chamber. The conduit curves into communication with the chamber in a transverse direction at an inlet position in the central chamber portion. A second portion of the chamber which is laterally opposed to the inlet position of the conduit defines a sloping shoulder to turn lateral blood flow from the conduit gently upwardly to define a gentle, circulatory flow of blood in an upper portion of the chamber. The chamber upper portion has a wall that carries projections to create blood flow eddys that slow the upward motion of bubbles present.
