ABSTRACT:
A hemo(dia)filtration apparatus (10) is described comprising a dialyzer (12) and two sterile filters (38) and (60). The first chambers (42) and (64) of both sterile filters (38) and (60) may be switched at least intermittently during flow through, thereby flushing out membranes (40) and (62) of both sterile filters (38) and (60) and effectively preventing an accumulation of germs and pyrogens. This prevents an increase in the transmembrane pressure (TMP), which reduces the likelihood of a rupture, thereby ensuring sterility of the dialyzer fluid and improving the operating safety of the hemodiafiltration apparatus (10).
