摘要： Disclosed is a method for separating a blood material into blood components by centrifugation, wherein when a multiple blood bag unit including a plurality of flexible blood bags (at least one of the flexible blood bags containing a blood material) liquid-tightly connected to at least one leukocyte-removing filter device through flexible tubes in a predetermined order is accommodated in a centrifuge bucket, at least the blood material-containing flexible blood bag or bags are inserted in the centrifuge bucket while placing at least the leukocyte-removing filter device outside of the centrifuge bucket, wherein the leukocyte-removing filter device is directly or indirectly secured relative to the rotor and a center of the filter device is located at a distance from an axis of the rotation shaft which is smaller than a distance between a pivotal axis of the turning of the centrifuge bucket and an axis of the rotation shaft at a portion thereof which has the rotor connected thereto. A centrifugal apparatus for practicing the method is also disclosed. By the method and apparatus of the present invention, the centrifugal force to be sustained by the filter device is reduced to a minimum due to the location of the filter device at a reduced distance from the rotation shaft, so that the danger of damaging or adversely affecting the filter device due to the centrifugal force is extremely reduced or eliminated.
摘要翻译：公开了一种通过离心将血液成分分离为血液成分的方法，其中，当至少液体密封地连接多个血液袋（包含血液材料的至少一个柔性血液袋）的多个血液袋单元时，一个以预定顺序通过柔性管的白细胞去除过滤器装置容纳在离心斗中，至少将含血液的物质的柔性血袋或袋插入离心斗中，同时至少将除去白细胞的过滤装置置于离心斗，其中所述除去白细胞的过滤装置相对于所述转子直接或间接地固定，并且所述过滤装置的中心位于距离所述旋转轴的轴线一定距离处，该距离小于所述旋转轴的枢转轴线之间的距离离心机斗的转动和旋转轴的轴线在其转子连接的部分处。还公开了一种用于实施该方法的离心设备。通过本发明的方法和装置，由于过滤装置的位置与旋转轴的距离减小，由过滤装置维持的离心力减小到最小，因此有损害或不利地的危险由于离心力而影响过滤装置的效果极大地降低或消除。
