초록 ▼

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).

대표청구항 ▼

[ What is claimed is:] [14.] A hemo(dia)filtration apparatus comprising:a dialyzer fluid source;a first sterile filter separated by a first germ-repelling membrane into a first sterile filter chamber and a second sterile filter chamber;a first portion of a supply line connecting the dialyzer fluid source to the first sterile filter chamber;a second sterile filter separated by a second germ-repelling membrane into a third sterile filter chamber and a fourth sterile filter chamber;a second portion of the supply line connecting the second sterile filter chamber to the third sterile filter chamber;a dialyzer separated by a dialyzer membrane into a first dialyzer chamber and a second dialyzer chamber, the second dialyzer chamber being connected into a blood path;a third portion of the supply line connecting the third sterile filter chamber to the first dialyzer chamber so that the second germ-repelling membrane is flushed by a flow of dialyzer fluid through the third sterile filter chamber;a discharge line connecting the first dialyzer chamber to a drain; anda substituate line connecting the fourth sterile filter chamber to the blood path.
