摘要： A blood treatment apparatus (1) comprising a degassing unit (15) receiving gas-containing fluid and supplying degassed fluid to a fluid chamber (3) of a blood treatment unit (2). The degassing unit has a gas separator (16), a degassing pump (18) to circulate fluid in a degassing line (12), a flow restrictor (17) for reducing the pressure in the degassing line (12), an absolute pressure sensor (19), and a control unit (20) 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.

摘要： A blood treatment apparatus comprising: a blood treatment unit; a blood line configured to extract blood from a blood source, pass the blood through the blood treatment unit and deliver treated blood to a target vessel; and a fluid line configured pass treatment fluid through the blood treatment unit and deliver used treatment fluid to a fluid sink. A flow divider is arranged in the fluid line separates treatment fluid into to a first fluid section and a second fluid section, thereby electrically isolating the fluid sections such that electrical current flowing in the fluid line between the fluid sections is limited. Related manufacturing and verification methods are also described.
