Abstract

patente de invenção "dispositivo e método para a remoção extracorpórea de toxinas, em particular citoquinas, especialmente para o tratamento de pacientes afetados por insuficiência orgânica aguda" preve que a remoção efetiva das citoquinas é realizada por uma primeira submissão do sangue a purificação por ultrafiltragem ou plasmafiltragem; subsequentemente alimentando o ultrafiltrado ou plasmafiltrado através de uma coluna de adsorção na qual o material adsorvente é o carbono ativado não recoberto e/ou resinas de poliestireno hidrofóbicas ou trocadoras de íons, tais como amberlite (mr), amberchrom (mr) ou ambersorb (mr); e então adicionando o ultrafiltrado ou plasmafiltrado purificado ao eluato recuperado a juzante do ultrafiltrado ou plasmafiltro; preferencialmente o ultrafiltrado ou plasmafiltrado é submetido a uma dupla fase de adsorção, primeiro através de uma coluna de carbono ativado e então através de uma coluna contendo resinas hidrofóbicas ou de troca iônica.
