Abstract
A closed emergency heart bypass system is disclosed herein for extra-corporeal blood circulation use which employs a minimum of components arranged in a series relationship. The components include a non-occlusive blood pump aspirating venous blood from an appropriate cannula for introduction to an oxygenator and a bubble-trapping device followed by return to a patient's body via an arterial cannula. Tubing interconnects the components and a bypass loop selectively joins the tubing adjacent to the venous and arterial cannulas for air displacement during initial pump priming and tube purging. Arterial blood can be accessed for sampling and for distal limb perfusion and a blood flow and monitoring console may be included in the system.
