    • After separation and during centrifuging a separated blood component is transferred from a source reservoir (2) into a tube (4) oriented against a centrifugal gradient. A cap (34) converts the separated layer from the reservoir into a columnar body and the centrifugal gradient prevents mixing of the columnar body in the tube (4) during further centrifuging. In one embodiment the tube has a volume sufficient to hold a desired fractional component from the source reservoir, and a diameter small enough to prevent mixing of the component when the gradient is removed. A support (69) holds the conduit wound about a spool transverse to the iso-g-lines of the centrifuge. The support (69) may be removably affixed to the cap (34). In a preferred embodiment the source reservoir (2) has a flexible wall, and pressure of the wall against an elevation (29) maintains pressure in the fluid system. Flow blocking (7) and flow regulating means are shown for delivering small fractional components to the tube or to a receiving reservoir at a desired rate. In another embodiment a make-up fluid reservoir maintains fluid pressure and a peristaltic pump controls the transfer of separated components. A table with movable clamps (65-67) is also shown for isolating the fractions in the tube after centrifuging.
    • 在分离之后和离心过程中,分离的血液成分从源储存器(2)转移到反对离心梯度取向的管(4)中。 盖(34)将分离的层从储存器转变为柱状体,并且离心梯度防止在进一步离心过程中管(4)中的柱状体的混合。 在一个实施例中,管具有足以保持来自源储存器的期望的分数分量的体积,以及直径足够小以防止当去除梯度时组分的混合。 支撑件(69)将导管缠绕在与离心机的等离子体线横向的线轴上。 支撑件(69)可以可移除地固定到盖子(34)上。 在优选实施例中,源储存器(2)具有柔性壁,壁相对于高度(29)的压力保持流体系统中的压力。 示出了流动阻塞(7)和流量调节装置,用于以期望的速率将小的分数分量输送到管或接收储存器。 在另一个实施例中,补充流体储存器保持流体压力,并且蠕动泵控制分离的部件的传送。 还显示了一个带有可移动夹具(65-67)的工作台,用于在离心后隔离管中的馏分。
