Abstract
In a process for testing filters () and () of treatment fluid of a hemodiafiltration apparatus (), each filter has a wet semipermeable membrane () which separates a gas-filled first chamber (and) from a liquid-filled second chamber (and). The first chambers are pressurized by a pump () supplying air, while the second chambers are placed in depression by a drainage pump () of used dialysis fluid. A first closed system is formed which includes the first chambers and a second closed system is formed which includes the second chambers. Two pressure gauges (Pand P) monitor the pressure in the two closed systems for a predetermined time. The monitoring provides indications relating to the filter integrity.
