摘要：
A blood treatment apparatus (2) comprising a blood treatment unit (10), a blood line (20), and a fluid line (30). The blood line is configured to extract blood from a blood source (21), pass the blood through the blood treatment unit and deliver treated blood to a target vessel (22). The fluid line is configured pass treatment fluid through the blood treatment unit and deliver used treatment fluid to a fluid sink (32). A flow divider (40) is arranged in the fluid line and separates treatment fluid into to a first fluid section (51) and a second fluid section (53), thereby electrically isolating the fluid sections (51, 53) such that electrical current flowing in the fluid line between the fluid sections is limited. The flow divider is verified to electrically isolate the first fluid section from the second fluid section. The verification may comprise applying a voltage between the two fluid sections, across the flow divider, and measuring the resulting current, wherein a current below a threshold indicates electrical isolation. The flow divider may comprise a drip chamber, or a pump. The flow divider may be configured to create a gas gap or periodically open and close the fluid line, for generating the separation of treatment fluid in the fluid line.
