Method and device for cleaning and clearing a semipermeable hollow-fibre system, especially of an artificial kidney

Abstract

Abstract The device comprises a channel (f1) for introducing washing liquid, in particular treated water from the system, and is provided with means (EVR1) for controlling the pressure and flow rate, a channel (g1) for introducing a treatment liquid and comprising a distributing pump (P) activated by the washing liquid and co-operating with a metering device (EVR2), the two channels joining (at J) to ensure mixing of the two liquids and then being connected to a set of inlet/outlet tubes of the two compartments of the exchanger (S) which are controlled by an assembly (E1) of electrovalves (EV1, EV2, EV3, EV4) and a device (C) for automatic or manual control and regulation of the parameters of the different cycles of preliminary cleaning, back-filtration, sterilisation and rinsing of the internal compartment and of the external compartment of the exchanger apparatus (S). <IMAGE>
