Device for extracorporeal blood treatment with gravimetric balancing and possibility for ultrafiltration

摘要

The invention relates to a device (1) for extracorporeal blood treatment, in particular a dialysis machine (1), having an internal fluid (2) to which a blood treatment unit (3), in particular a dialyzer (3), can be connected, the internal fluid (2) at least a balancing chamber (4, 5) on the fresh-current side for balancing fresh-treatment liquid flowing to the blood treatment unit (3) and at least one balance-side balancing chamber (6, 7) for balancing the treatment liquid discharged from the blood treatment unit (3), the apparatus (1) comprising a measuring device (1) 32) for gravimetrically detecting treatment liquid in the fresh-current-side balancing chamber (4, 5) and / or a measuring device (32) for gravimetrically detecting treatment liquid in the balancing chamber (6, 7). The invention further relates to a method for balancing treatment liquid in such a device (1).
