Title:
CELL REMOVAL METHOD, CELL REMOVAL SYSTEM, AND WHITE BLOOD CELL REMOVAL METHOD
Document Type and Number:
WIPO Patent Application WO/2011/115291
Kind Code:
A1
Abstract:
The removal rate of the white blood cells by means of a filter is improved when white blood cells are removed from blood. A plurality of separation layers, which has a white blood cell concentration gradient, is formed by applying centrifugal force to the blood housed in a blood bag during centrifugation. The separation layers are passed through a filter starting from the side in which the white blood cell concentration is the lowest, thereby removing the white blood cells from the separation layers. The separation layers from which the white blood cells are removed are housed in a first blood component bag.
