ABSTRACT:
Method and apparatus is disclosed relating to the use of a plasma receiving assembly including a container and closure cap adapted to permit aseptic handling, storage and shipment of blood plasma. One aspect of the method is to form the plasma receiving assembly by placing a plasma receiving container within an overwrap having a gas permeable bacterial filter such that the container and overwrap may be gas sterilized followed by mechanical sealing of the container while still in the overwrap. The method further provides for use of the overwrap to lessen the chances of contamination during handling and transfer of the blood plasma including the steps of forming the container in a rigid standardized cylindrical form and limiting the volume of plasma placed in each container so that the plasma may be frozen and removed automatically. The method is facilitated by a novel closure cap having a cover adapted for axial movement between a partially open position in which sterilized gas may pass into and out of the container and a fully closed position in which the container is hermetically sealed for shipment. Because the closure cap cover may be operated by direct pressure applied to the upper surface, operation of the closure cap cover when the container is within the overwrap is greatly facilitated.
