    Abstract: A method of washing blood mixed with undesirable elements not normally found in healthy whole blood to remove the undesirable elements, the method comprising: separating the blood into components according to relative densities of the components with a rotating centrifuge bowl; providing a port through which fluid exits the bowl, the exiting fluid having a concentration of undesirable elements; flowing washing solution into the centrifuge bowl at an initial flow rate; monitoring the fluid exiting the bowl with an optical sensor having an output signal indicative of the composition of the exiting fluid; and increasing and decreasing the flow rate of the wash solution as a function of the output signal.

    Abstract translation: 一种洗涤血液的方法,所述血液与健康全血中通常不能发现的不需要的元素混合以除去不需要的元素,所述方法包括:根据所述组分的相对密度用旋转的离心碗将血液分离成组分; 提供流体离开碗的端口,排出的流体具​​有不期望的元件的浓度; 流动的洗涤溶液以初始流速进入离心机碗; 用具有指示出射流体的组成的输出信号的光学传感器监测离开碗的流体; 以及根据输出信号增加和减少洗涤溶液的流速。
