1. Apparatus for collecting and storing biological fluids in a flexible container, comprising:

  • (a) a rigid outer chamber having a fluid inlet opening and a vacuum port, said flexible container being disposed within said outer chamber in communication with said fluid inlet opening for receipt of fluid therein upon creation of a vacuum within said outer chamber through said vacuum port;

    (b) inner chamber means disposed within said outer chamber for receipt of said flexible container therein, said inner chamber being split into at least two segments which are movable between a closed position and an open position, said inner chamber means defining a smaller volume when in its closed position than when in its open position;

    (c) bladder means disposed within said outer chamber between said inner chamber means and said outer chamber, the interior of said bladder means being in communication through an opening in said outer chamber with the atmosphere so as to cause said bladder means to expand and fill a space between said inner chamber and said outer chamber upon the application of a vacuum to said outer chamber so as to exert a pressure on said inner chamber sections and thereby move said sections toward one another into its closed position; and

    (d) retainer means depending downward from the underside of a lid member, said lid member being pivotally mounted to said outer chamber adjacent to the upper end thereof so as to close off the upper end of said outer chamber when in its closed position, said retainer means extending downward towards said inner chamber means and being effective to limit the expansion of said flexible container.
