Abstract: A system (8) is provided for weighing and monitoring flow from multiple fluid sources (76) into a flow system (10) wherein incoming fluid is received in a weighing bag (80) attached to a control system for monitoring the amount of fluid passed through the weighing bag (80) and for preventing admission of air into the flow system (10). An alarm attached to the weighing bag (80) warns when fluid in the weighing bag (80) is approaching empty, so that the fluid in the weighing bag (80) can be replenished from the fluid source (76) before the weighing bag (80) runs dry. If fluid in the weighing bag (80) is not replenished, the system automatically shuts down. The fluid pump (72) can be absolutely calibrated using the controlled admission of known amounts of fluids into the weighing bag (80) so that the amount of fluid introduced into the flow system (10) through the weighing bag (80) can be calculated automatically.
Abstract translation: 流体从源容器流动到称重容器，并从称重容器流出，流向称重容器的流量被控制以将称重容器中的流体重量保持在预定的限度内。 如果称重容器中的量低于警告量，则可以提供警告，然后液体从不同的源被引导到容器。 如果重量低于故障安全量，称量容器的流量可能会关闭。

Abstract: Fluid is flowed from a source container to a weighing container and from the weighing container, the flow to the weighing container being controlled to keep the weight of fluid in the weighing container within predetermined limits. A warning may be provided if the amount in the weighing container falls below a warning amount, fluid then being directed to the container from a different source. Flow from the weighing container may be shut down, if the weight falls below a fail safe amount.

Abstract: The system includes a plasmapheresis instrument (10) and a harness set applied to the instrument. The harness set has a single venepuncture needle (40) and is configured, when applied to the instrument, to pump blood from a donor through a separator (36) for collection of its constituent parts in a reservoir (38) and a collection container (48), respectively. During an infusion cycle, which alternates with the collection cycle, the blood constituent from the reservoir (38) and a replacement fluid are mixed externally of the reservoir (38) and pumped to the donor.
