ABSTRACT:
An extra corporeal support system has an inlet catheter which is positioned with its distal end in the right atrium or vena cava of the patient. A roller pump with an inlet pressure sensor positioned close to its inlet to sense the pressure in the inlet line which pumps the blood through the system to any output catheter positioned in the arterial system of the patient. The system has a shunt with blocking valves to block the flow automatically in the event of an unsafe condition. The system has a microprocessor based controller for automatic operation of the system components including a servo motor for driving the roller pump at a speed to precisely maintain the inlet pressure at a preselected point. The system includes a blood treatment device such as an oxygenator.
