SE DESCRIBE UN DISPOSITIVO (10) DE HEMO(DIA)FILTRACION CON DIALIZADOR (12) Y DOS FILTROS (38) Y (60) ESTERILES. LA PRIMERA CAMARA (42) O (64) DE AMBOS FILTROS (38) O (60) DE ESTERILIZACION SON CONECTABLES AL MENOS EN TIEMPO PARCIAL EN EL FLUJO DE PASO, DE TAL MODO QUE LAS MEMBRANAS (40) O (62) DE AMBOS FILTROS (38) O (60) DE ESTERILIZACION SON ENJUAGADOS DE FORMA LIBRE Y SE EVITA LA RECOLECCION DE GERMENES Y PIROGENOS DE FORMA FIABLE. CON ELLO SE EVITA UNA ELEVACION DE LA PRESION (TMP) DE TRANSMEMBRANA, DE MODO QUE ES IMPROBABLE LA GENERACION DE UNA RUPTURA Y CON ELLO SE GARANTIZA LA ESTERILIDAD DEL LIQUIDO DE DIALISIS Y SE MEJORA LA SEGURIDAD DEL DISPOSITIVO (10) DE HERMODIAFILTRACION. The haemofiltration device (10) uses 2 sterile filters (38,60) and a dialysator divided by a membrane into a first chamber (14) in a dialysis fluid flow path and a second chamber (16) in a blood flow path. One chamber (42,64) of each sterile filter is selectively switched in the dialysis fluid flow path, for rinsing the filter membranes (38,60) to prevent collection of germs, etc. The dialysis fluid flow is controlled during rinsing to prevent the trans-membrane pressure increasing, to prevent rupture of the membrane, ensuring the sterility of the dialysis fluid.
