APPARATUS AND METHOD FOR TESTING INTEGRITY OF AN ULTRAFILTER MEMBRANE
An apparatus for extracorporeal treatment of blood (1) has a supply line (2), a waste line (13) and an ultrafilter (19; 70) inserted in the supply line (2). An air inlet line is connected to the first chamber (21; 72) of the ultrafilter (19; 70) and a pressure sensor (41) configured for detecting pr...

| description | An apparatus for extracorporeal treatment of blood (1) has a supply line (2), a waste line (13) and an ultrafilter (19; 70) inserted in the supply line (2). An air inlet line is connected to the first chamber (21; 72) of the ultrafilter (19; 70) and a pressure sensor (41) configured for detecting pressure in the waste line (13). A controller (50) is configured to carry out, with the hydraulic circuit (100) 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 (19; 70) is also disclosed. |
