External filtration and the nonpoisonous conversion system and method generally, the stage which separates the ultrafiltration liquid from the cell component of the blood, becoming independent with the cell component in the recycling circuit, the stage which deals with the ultrafiltration liquid, include the ultrafiltration liquid and the stage which re-mixes the cell component, and resets all blood to the patient the stage which were dealt with. The recycling circuit generally in order to execute the disposal which is selected includes the active cartridge which includes the active cell which functioning is done, the active cell is C3A cell stocks in several features.体外ろ過および無毒化システムおよび方法は概して、血液の細胞成分から限外ろ過液を分離する段階、再循環回路で細胞成分と独立して限外ろ過液を処置する段階、処置された限外ろ過液と細胞成分を再混合する段階、および患者へ全血を戻す段階を含む。再循環回路は概して、選択された処置を実施するよう機能する活性細胞を含む活性カートリッジを含み、いくつかの態様において、活性細胞はC3A細胞株である。
