An apparatus for extracorporeal treatment of blood () has a supply line (), a waste line () and an ultrafilter () inserted in the supply line (). An air inlet line is connected to the first chamber () of the ultrafilter () and a pressure sensor () configured for detecting pressure in the waste line (). A controller () is configured to carry out, with the hydraulic circuit () in by-pass configuration, an integrity test procedure for detecting if the ultrafilter membrane has multiple or single fiber breaks. A method of testing the ultrafilter () is also disclosed.

Apparatus and method for testing integrity of an ultrafilter membrane

It is described an extracorporeal blood treatment apparatus () with a user interface () device capable configuring and allowing execution of one or more isolated ultrafiltration tasks during the course of a dialysis treatment. The extracorporeal blood treatment apparatus () is controlled in a normal mode, where dialysis fluid is fed to the blood treatment unit (), and in an isolated ultrafiltration mode, where fresh dialysis fluid is no longer fed to the blood treatment unit ().

Extracorporeal blood treatment apparatus and method of setting an extracorporeal blood treatment

An apparatus for extracorporeal blood treatment, comprising a treatment unit () having a first chamber () and a second chamber () separated from one another by a semipermeable membrane (), a blood removal line () connected in inlet with the first chamber () and a blood return line () connected in outlet with the first chamber; an infusion line () of a replacement fluid and a fluid evacuation line () connected in outlet from the second chamber. A regulating device () of a transmembrane pressure is active on at least one of the lines and a control unit () is configured to: command the regulating device () by setting a first increase (&#x3b4;TMP), determine a value of a control parameter (&#x3c6;) corresponding to the first increase, compare the value of the control parameter (&#x3c6;) with a reference value (&#x3c6;) and, if the value of the control parameter is greater than the reference value, command the regulating device () by setting a second increase (&#x3b4;TMP) which is greater than the first increase (&#x3b4;TMP).
