Continuous flow separation chamber with weir disk

A centrifuge bowl for continuous separation of whole blood comprising:

• an outer body rotatable about a longitudinal axis of the centrifuge bowl, the outer body having a main body defining an interior cavity, a neck portion extending proximal to the main body, and a shoulder connecting the main body and the neck portion, the outer body having a main wall;
• a top core located within and rotatable with the outer body, the top core being coaxial with the outer body and including a chimney extending through the top core along the longitudinal axis of the centrifuge bowl;
• a separation region located between the top core and the outer body, rotation of the centrifuge bowl separating the whole blood within the separation region into a first blood component and a second blood component;
• an inlet port for introducing whole blood into the centrifuge bowl;
• an inlet tube fluidly connected to and extending distally from the inlet port and through the chimney, the inlet tube configured to introduce the whole blood into an introduction region;
• a first blood component outlet port for drawing a first blood component out of the centrifuge bowl;
• a first blood component extraction tube extending from the first blood component outlet port to a first blood component extraction region;
• a second blood component outlet port fluidly connected to the separation region and for drawing a second blood component from the centrifuge bowl;
• a weir disk extending from the main wall and radially inward into the neck portion of the outer body, the second blood component flowing over the weir disk into the neck portion of the outer body prior to exiting the centrifuge bowl via the second blood component outlet port;
• and
• a centrifuge bowl rotary seal attached to the outer body and fluidly coupling the inlet port, first blood component outlet port, and second blood component outlet port to the outer body.
