ABSTRACT:
An apparatus is provided for autologous sequestration of blood from a patient prior to, during and after surgery. Sequestered blood contained in an assembly of oxygenated blood collection bags is kept in fluid contact with the patient throughout surgery, thereby assuring continuity with the patient's circulatory system. The plurality of blood collection bags is interconnected with a corresponding plurality of valves which is interconnected with a plurality of flexible tubes which is attached to a patient's right atrium or a peripheral artery. Following induction of anesthesia in the operating room, a patient's blood is sequestered into a collection bag assembly which forms a closed circuit blood reservoir system. Collected blood during surgery trickles back into the patient's blood system, thereby emulating venous blood flow. The collection bags are agitated and oxygenated to promote the functionality and longevity of the platelets in the sequestered blood.
