Abstract
The present invention is directed to improved methods and apparatus for the collection of blood, which are particularly useful for autotransfusion purposes. The apparatus includes a conventional blood transfer bag which is in turn placed in fluid communication with an air-blood separator to form a collection system. This system is particularly adaptable for use in the surgical setting in that it can operate at high vacuum while minimizing hemolysis. This is accomplished by early separation of air from the blood as the blood is collected. The air-blood separator and the interior of the blood bag are placed in communication with a vacuum source. As a result, there is a pressure equalizing feature inherent within the device. This allows the blood to continue to flow through the device into the blood bag without extending or opening the blood bag. As a result, there is minimal air-blood interface as the blood enters the blood bag.
