Abstract
Blood treatment/dialysis systems are disclosed. The systems include a water treatment unit, preferably of the reverse osmosis type, whose outlet has connected thereto a water supply line provided with a number of branch connections having fluidly coupled thereto blood treatment/dialysis machines in a selective manner, and a drain line through which exhausted blood treatment fluid can be discharged from fluidly coupled blood treatment/dialysis machines. Also disclosed is a machine-external heat exchanger, which is connected to the water supply line upstream of the branch connections on one side and to the drain line on the other side.

An extracorporeal blood treatment system comprising:
- a stationary system area including:
- a water treatment unit having an outlet connected to at least one water supply line that opens into at least one line section provided with a number of branch connections and at least one drain line through which exhausted blood treatment/dialysis fluid can be discharged;
- and
- a non-stationary system area including:
- a number of blood treatment machines fluidly coupled to the branch connections and the at least one drain line in a selective manner;
- and
- a stationary heating unit disposed externally to the blood treatment machine and comprising a first heat exchanger (WT1) having one side (WT1/1) connected to the at least one water supply line between the water treatment unit and the line section including the branch connections, and having the other side (WT1/2) connected to the at least one drain line.
