Blood treatment apparatus including flow divider for limiting an electrical current

A blood treatment apparatus comprising:

• a blood treatment unit including a fluid inlet and a fluid outlet;
• 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;
• a fluid line including
• an upstream fluid line configured to receive electrically conductive treatment fluid from a fluid source and pass the electrically conductive treatment fluid to the fluid inlet of the blood treatment unit such that the electrically conductive treatment fluid interacts with the blood within the blood treatment unit to form used electrically conductive treatment fluid, and
• a downstream fluid line connected to the fluid outlet of the blood treatment unit for delivering the used electrically conductive treatment fluid to a fluid sink;
• and
• a flow divider arranged in the downstream fluid line and configured to separate the used electrically conductive treatment fluid in the downstream fluid line into to a first fluid section and a second fluid section, thereby electrically isolating the first and second fluid sections such that electrical current flowing in the first fluid section is prevented from reaching the second fluid section.
