    • A drive assembly for a centrifugal processing system is provided for rotating the yoke assembly (36) about a first axis at a first angular velocity and rotating the chamber assembly (30) coaxially with the yoke assembly at a second angular velocity A drive motor (60) is provided for rotating the yoke assembly at the first angular velocity A stationary gear (70 is mounted coaxially with the yoke assembly, with a drive linkage (72) comprising a shaft (74) secured to the yoke assembly so as to be rotatable therewith. The shaft is operatively connected on its first end to the stationary gear (70), so that the shaft rotates about its axis as the yoke assembly (36) rotates relative to the stationary gear. The shaft (74) is rotatably connected on its second end to the chamber assembly (30), so that when the shaft is rotated, the shaft rotates the chamber assembly. Preferably, the yoke assembly (36) comprises a first arm (38) and a second arm (40), with the chamber assembly (30) being rotatably secured to the first arm and the first arm being pivotably connected to the second arm, and the shaft (74) being flexible.

    • Blood separation systems and methods are provided for detecting lipids in plasma that has been separated from a plasma-containing fluid, such as blood. The system includes a fluid processing region in which a plasma-containing fluid is separated into plasma and other fluid components. A plasma flow path is associated with the fluid processing region for the flow of at least a portion of the separated plasma into or out of the region. A lipid detector shines blue and/or ultraviolet light through the separated plasma in the plasma line to optically detect the presence of lipids therein. The lipid detector may be used alone or in combination with a hemoglobin detector to reduce the number of false hemoglobin alarms or an interface detector for improved detection and correction of the location of an interface between separated fluid components in the fluid processing region.
    • 提供血液分离系统和方法用于检测等离子体中已经从含血浆的流体例如血液中分离的脂质。 该系统包括流体处理区域,其中等离子体流体被分离成等离子体和其它流体组分。 等离子体流动路径与用于使分离的等离子体的至少一部分流入或流出该区域的流体处理区域相关联。 脂质检测器通过等离子体系中的分离的等离子体发出蓝色和/或紫外光,以光学检测其中脂质的存在。 脂质检测器可以单独使用或与血红蛋白检测器组合使用以减少假血红蛋白警报的数量或接口检测器,以改进检测和校正流体处理区域中分离的流体成分之间的界面的位置。

    • Methods and systems are provided for anticoagulating blood. Whole blood is drawn from a donor into a system at a draw flow rate. Anticoagulant from an anticoagulant source is pumped into the system at an anticoagulant flow rate to mix with the blood. The anticoagulated blood may be subsequently processed in any of a number of known ways, including separating it and removing at least a portion of one of the components of the blood. Thereafter, at least a portion of the remaining blood may be returned to the donor. The anticoagulant flow rate is independent of the draw flow rate and can be based on a number of factors, including the weight of the donor and the rate at which the donor can metabolize the anticoagulant.
    • 提供用于抗凝血的方法和系统。 将全血从供体抽出到抽吸流量的系统中。 来自抗凝血剂来源的抗凝血剂以抗凝血流量泵入系统以与血液混合。 随后可以以许多已知方式中的任何一种处理抗凝血液,包括分离血浆并除去血液中一种成分的至少一部分。 此后,剩余血液的至少一部分可以返回给供体。 抗凝血剂流速与抽吸流速无关,可以基于许多因素,包括供体的重量和供体可以代谢抗凝血剂的速率。
