    • A composite of interconnected bags comprises a blood collecting bag, a preserving liquid bag, and a blood plasma bag. The interior of the bag body of the blood collecting bag is divided by a partition strip into an empty space and an empty space of the shape of a strip, with the two empty spaces mutually communicating near the end part of the partition strip. The blood collected in the blood collecting bag is centrifuged. The upper layer of blood plasma resulting from the centrifugation is discharged via a tube to the blood plasma bag. Then, the erythrocyte preserving liquid in the preserving liquid bag is advanced through the tube, the empty space, and a connecting part and added upwardly from below to the concentrated erythrocyte left behind the empty space. The erythrocyte preserving liquid, without being stirred, is allowed to ascend and mingle with the concentrated erythrocyte with the elapse of time. Thus, the present invention provides a erythrocyte preparation excellent in quality and fee from occurrence of floccules.
    • 互连袋的复合体包括采集袋,保存液袋和血浆袋。 血液收集袋的袋体的内部被分隔条分隔成空的空间和带状的空的空间,两个空的空间在分隔带的端部附近相互连通。 收集在血液收集袋中的血液被离心。 由离心产生的血浆的上层通过管排出到血浆袋。 然后,保存液袋中的红细胞保存液通过管,空的空间和连接部分前进,从下方向上添加到留在空白空间的浓缩红细胞。 不经搅拌的红细胞保存液随着时间的推移升高并与浓缩的红细胞混合。 因此,本发明提供了从絮凝物的出现优异的质量和费用的红细胞制剂。
