Abstract
Abstract A blood collection device having a blood-collecting tube (7), a needle (9), a blood container (1) connected to the needle (9) by the blood-collecting tube (7). The blood container (1) has a blood-storing space (5) containing anticoagulant solution. Two blood-component containers (17, 21) and an erythrocyte-preserving solution container (27) are connected to the blood container (1) by a blood-component supplying tube (13) and a tube (25). The containers (1, 17, 21, 27) are made of soft material. A branching member (29) is coupled to the blood-collecting tube (7) and located between the blood container (1) and the needle (9). A tube branching from the blood-collecting tube (7) is connected to a filter (31). The filter (31) allows passage of gas but substantially prevents passage of blood, bacteria, microorganism and the like. A flow stopper (33) connects the blood-collecting tube (7) to the filter (31). The flow stopper (33) comprises a breakable member (37, 41, 43) closing the branch tube. When the breakable member (37, 41, 43) is broken, the branch tube communicates with the filter (31).
