This invention provides a method and apparatus for a hemodiafiltration delivery module (100) that is used in conjunction with a UF controlled dialysis machine to enable hemodiafiltration therapy to be performed. Apparatus includes a dialysis machine and an extracorporeal circuit in communication with a diafiltration module including a first conduit (120) for receiving from and discharging fluid to dialysis machine and a second conduit (64) to selectively receive a diverted fluid and including at least one sterilizing filter (92) for filtering the diverted fluid to produce substitution fluid which is delivered to the extracorporeal circuit and a control unit (110) responsive to characteristics of fluid or blood to prevent flow of the substitution fluid to the extracorporeal circuit when at least one of the characteristics meets a prescribed criteria.

L'invention concerne un procédé et un appareil pour module d'hémodiafiltration (100) utilisé conjointement avec une machine de dialyse à ultrafiltration (UF) contrôlée pour appliquer un traitement d'hémodiafiltration. Cet appareil comprend une machine de dialyse et un circuit extracorporel relié à un module de diafiltration comprenant un premier conduit (120) qui permet de recevoir le fluide de la machine de dialyse et de le décharger dans cette dernière et un second conduit (64) qui permet de recevoir sélectivement un fluide dévié, ce second conduit étant relié à un filtre de stérilisation (92) permettant de filtrer le fluide dévié pour obtenir un fluide de substitution lequel est fourni au circuit extracorporel, et enfin, une unité de commande (110) sensible aux caractéristiques du fluide ou du sang, qui empêche le fluide de substitution de s'écouler vers le fluide extracorporel lorsqu'au moins l'une des caractéristiques correspond à un critère prescrit.
