Abstract:
An assembly for controllably transferring fluids from a plurality of individual source containers through a transfer set to form a desired mixture in a receiving container, the set placing at least one of the source containers in fluid communication with the receiving container, the assembly comprising:a pump operatively acting on at least one of the fluids to force a flow of said fluid along at least a portion of the set, the rate of the flow varying in at least partial dependence on a characteristic of said fluid;a flow rate distinguishing sensor in operative contact with the receiving container adapted to generate signals that are indicative of flow rate of fluid received therein;a fluid type sensor in noninvasive sensory contact with the fluid flowing within the set to determine a characteristic of the fluid and adapted to generate signals indicative of said characteristic; and,processing means operably connected to receive said flow rate indicative signals and said characteristic indicative signals and being adapted to selectively analyze said signals and confirm the identity of fluids being transferred.
