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.

An apparatus for collecting blood from a patient for reinfusion comprising: means for separating air from the blood collected for reinfusion; first conduit means for conveying the blood collected from the means for separating air from the blood to a blood collection receptacle; a blood collection receptacle having a blood inlet and a vacuum port, the blood receptacle being readily removably from the means for conveying the blood after receipt of blood and being capable of being maintained in a collapsed configuration prior to receipt of collected blood and the blood collection receptacle expanding from a collapsed configuration to an expanded configuration in relation to the amount of blood which has flowed into the receptacle and such that further contact between air and blood flowing into the receptacle is avoided; and second means for placing a source of vacuum in communication with the blood receptacle and the separating means.
