Abstract:
An assembly for controllably transferring fluids from a plurality of individual source containers through a transfer set of the type which has a plurality of conduits through which fluid can pass to form a desired mixture in a receiving container, each conduit of the set being adapted to place one of the source containers in fluid communication with the receiving container, the assembly comprising:a pump assembly being adapted to operatively act on fluid in at least one conduit to force a flow of said fluid therethrough, the rate of the flow varying in at least partial dependence on a characteristic of said fluid, said pump assembly operating responsive to predetermined signals being applied thereto;a first sensor adapted to be in operative contact with the receiving container adapted to generate a signal that is indicative of the weight of the receiving container and its contents;a second sensor being adapted to be positioned in close proximity to said at least one conduit when properly installed, said second sensor being in noninvasive sensory contact with fluid present in said at least one conduit, and adapted to sense and selectively determine the absence of said at least one conduit, the absence of fluid in said at least one properly installed conduit, and a characteristic of the fluid present in said at least one conduit and generate signals that are indicative of such determination;a controller for controlling the operation of said apparatus, including said pump assembly and for processing said signals from said first and second sensor and being adapted to generate preselected alarm signals in response to predetermined conditions; and,an alarm indicator operatively connected to said controller for providing preselected alarm indications in response to preselected alarm signals being generated by said controller.
