Systems, Apparatus and Methods for Processing Autologous Blood for Reinfusion into a Patient

A blood reinfusion system, comprising:

• a blood processing canister comprising a housing, said housing comprising an internal fluid passageway and a bottom blood collection chamber,
• said internal fluid passageway sized and configured to receive blood therein and allow said blood to be transmitted therethrough, said internal fluid passageway in communication with said bottom collection chamber,
• said internal fluid passageway comprising a venturi region, said venturi region comprising an inlet region, a restricted flow path region and an outlet region, said inlet region of said venturi region defining a top blood collection chamber,
• said venturi region comprising a first length,
• said inlet region comprising a cone angle in the range of 26° to 66° and a second length in the range of 25% to 35% of said first length of said venturi region,
• said outlet region comprising a cone angle in the range of 10° to 45° and a third length in the range of 75% to 85% of said first length of said venturi region,
• said venturi region further comprising a gravity-driven blood filtering system adapted to extract a plurality of impurities from said blood, whereby purified whole blood is obtained,
• said internal fluid passageway configured and adapted to transmit said purified whole blood to said bottom blood collection chamber.
