ABSTRACT:
A membrane blood oxygenator having a mechanism for automatically maintaining the total pressure of the oxygenating gas near yet below that of the blood across the membrane is described. This includes a valve for restricting the flow of oxygenating gas exiting the oxygenator with the pressure of the blood exiting the oxygenator. A tubing communicates the pressure of the exiting blood to the valve to activate the valve.
