Abstract
A drainage and autotransfusion system is coupled with a closed wound drain. A detachable suction reservoir provides suction to the system to facilitate drainage of blood from the wound into a substantially rigid collection container. This blood is adapted to be transferred into an attached blood bag which in turn may be coupled with an administration set for reinfusion. While blood is reinfusing, blood collection into the container continues. Following autotransfusion, the suction reservoir can be converted to a suction device for blood collection directly from the closed wound drain.
