Abstract
A blood treatment apparatus () comprising a degassing unit () receiving gas-containing fluid and supplying degassed fluid to a fluid chamber () of a blood treatment unit (). The degassing unit has a gas separator (), a degassing pump () to circulate fluid in a degassing line (), a flow restrictor () for reducing the pressure in the degassing line (), an absolute pressure sensor (), and a control unit () designed to control the speed of said degassing pump from the absolute pressure signal emitted by the pressure sensor. The apparatus comprises a dialysis machine provided with a device for preparing on-line a dialysis liquid from water and concentrates. The apparatus achieves an accurate and reliable regulation of a desired concentration of gas in the dialysis liquid.
