Blood flows in extra-corporeal blood circulation into a blood oxygenator. The oxygenating gas enters the blood streams through a means providing oxygenating gas injection, adjacent a means providing blood inlet. The pair of means co-react to provide two-phase flow of blood and oxygenating gas bubbles for the two-phase fluid flow guide. The flow guide has a multiplicity of fluid guide, solid walls of equal length, one wall uniformly closely spaced to another wall. The spaced walls are held in a boundary case by wall securing means which provide a uniform base terminus position and a uniform top terminus position for the walls. The boundary case can have a case length at least equal to the fluid guide wall lengths and greater. The fluid guide solid wall can have multiple, uniform cross section flow control channels disposed in the wall, extending normally to the base terminus and the top terminus of the wall. The flow control channels stabilize the upward flow of the two-phase blood and oxygenating gas combination. The flow control channels stabilize the gas bubble-liquid interface flow geometry, and facilitate the rapid fixation of oxygen by the blood and the release of carbon dioxide into the gas phase exiting from the top terminus of the two-phase fluid flow guide.
