  • Patent number: 6045546
    Abstract: Apparatus and method for collecting, processing, and storing blood components, such as plasma. The method involves collecting the blood component in a flexible storage bag manufactured from ethylene vinyl acetate EVA, having a composition of between about 9% and about 18% vinyl acetate by weight of total EVA co-polymer. The EVA bag is sealed, and the sample is frozen in the bag at a temperature of at least as low as -30.degree. C. to form a substantially solid pellet contained in the storage bag. The bag then is fractured and the pellet is removed in its intact, frozen form. The co-polymer bag may have an inner surface with an etched or embossed pattern of sufficient dimensions to permit removal of the plasma in a frozen state from the storage bag.

  • Patent number: 4975186
    Abstract: Blood and blood component container having in continuous communication therewith a receptacle adapted to receive and define a given component or sub-component when contents in the container are separated. In preferred embodiments, the container is a flexible bag having a tapered portion adjacent the receptacle to assist migration of a given component or sub-component into the receptacle during centrifugation and at least a portion of the container is supported by a cup-like device, the inner surface of which conforms to the outer surface of the bag and communicating receptacle.
