Abstract

dialisador. um dialisador composto de primeira e segunda câmaras de diálise e uma câmara intermediária interposta entre as primeira e segunda câmaras de diálise. cada câmara de diálise em primeira e segunda extremidades opostas e contém um elemento de filtro que separa a câmara em um compartimento de sangue e um compartimento de dialisado. cada um dos compartimentos se estende entre primeira e segunda extremidades. cada uma das câmaras tem uma respectiva entrada ou saída de sangue e entrada ou saída de dialisado arranjadas de modo que sangue e dialisado escoem em contra corrente um com o outro em ambas as câmaras. a câmara intermediária é conectada para formar uma passagem de escoamento de sangue livre de dialisado entre os compartimentos de sangue.
