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 tubing. When the bag is filled with a mixture of blood components which are then separated, the tapering end portion expands to form a funnel-like guide for directing a separated component from the bag through the tubing in a substantially unobstructed manner. Bag is especially useful for separating and isolating the components of a neocyte/gerocyte red blood cell mixture.
