    • A concentrator (10) is used for concentrating a fluid, particularly a plasma component out of blood, for treatment of a patient. The concentrator apparatus (10) includes a main housing (12) defining a centrifuge chamber ( 14), that also holds the filter (38). The concentrator (10) allows viewing of the fluid after centrifuging, with an outlet port (32) positionable at a height corresponding to the level of the fraction of the fluid to be further concentrated. Once the fluid is centrifuged, a portion of the fluid is drawn through the outlet (32), and then pressured past the filter (38) to further concentrate the fluid using the same vessel (10) as used for centrifuging. The same plunger (68) is preferably used to draw centrifuged fluid from the centrifuge chamber (14) as to pressure the centrifuged fluid past the filter (38).
    • 浓缩器(10)用于将流体,特别是血液中的血浆成分浓缩,用于治疗患者。 集中器装置(10)包括限定离心机室(14)的主壳体(12),其也保持过滤器(38)。 浓缩器(10)允许在离心之后观察流体,其中出口端口(32)可定位在与要进一步浓缩的流体的分数水平相对应的高度处。 一旦流体被离心,一部分流体被抽出通过出口(32),然后压力通过过滤器(38),以进一步使用与用于离心的容器相同的容器(10)浓缩流体。 优选地使用相同的柱塞(68)来从离心机室(14)中抽取离心的流体,以将离心的流体压力通过过滤器(38)。
