Abstract
In a blood bag system for plasma transfusion and cell return including two or more blood bags containing anticoagulant and connected to a puncture needle through two or more branch tubes and a common main tube, a cell return port is connected to the branch and a breakable flow path closure is inserted in one branch tube adjacent the branch. When broken, the flow path closure allows fluid communication through the branch tube. Blood is first collected in the first blood bag, which bag is sealed when filled and separated from the system. Then, the flow path closure is manually broken to permit blood collection into the second blood bag.
