Abstract
The invention is directed to blood processing method and apparatus utilizing a centrifugation bowl with a filter core disposed within the bowl. The centrifugation bowl includes a rotating bowl body defining an enclosed separation chamber. A generally cylindrical filter core is disposed inside the separation chamber. The filter core includes a filter membrane that is sized to block at least white blood cells, but to allow plasma to pass through. The filter core is generally arranged within the separation chamber such that plasma is forced to pass through the filter core before being removed from the centrifugation bowl. The addition of the filter core provides an efficient, low-cost method for recovering a “purer” plasma fraction from a donor.
