ABSTRACT:
A generally flat, elongated edge-sealed polymeric blood bag having a length to width ratio of at least 2 to 1 and one end portion in tapering communication with a connected single tubing which in turn is in closed communication via a Y-connector with both a bag access port and at least one other Y-connector. The second Y-connector is in closed communication with at least one auxiliary bag, preferably two auxiliary bags. Once the upper neocyte portion is expressed from the elongated blood bag the lower, more dense gerocytes can be saved in the original elongated bag or expressed into another connected bag via the Y-connector assembly for subsequent use or storage. The bag system is especially useful for separating and isolating both components of a neocyte/gerocyte red blood cell mixture in an open system and for providing a means for saving the otherwise discarded gerocytes for subsequent use. A physiological solution can be introduced via the Y-connector assemblies into the elongated bag to reconstitute the dense gerocytes.
