Abstract
An intraoperative blood recovery system and method for salvaging operative blood while simultaneously delivering previously collected blood to a reinfusion system. A blood collection and transfer reservoir, having multiple compartments which can be separated by vacuum or pressure barriers, is designed to maintain a continuous suction for blood inflow while blood previously collected can be simultaneously transported through the reservoir to achieve an uninterrupted flow of blood into and delivery of blood out of the reservoir.
