A method for priming a blood tubing set having a venous line and an arterial line whose connections at the patient side are in communication with two separate inlets of a chamber of, in particular, a bag and whose connections at the machine side are in communication with a dialyzer. The method includes the steps of parallel filling of both the venous and the arterial lines via a feed line so that priming liquid flows through both inlets into the chamber; and circulation of the priming liquid in the circuit of the lines, the dialyzer and the chamber via a pump so that one of the inlets of the chamber acts as an inlet and the other as an outlet.

1. A method for priming a blood tubing set having a patient side and a filter side, said blood tubing set including a venous line and an arterial line each having a connection at the patient side and a connection at the filter side, said connections of the venous and arterial lines at the patient side being in communication with two separate ports of a chamber of a bag and said connections of the venous and arterial lines at the filter side being in communication with a dialyzer, said venous and arterial lines, said dialyzer and said chamber forming a circuit, said method comprising the steps of: starting the priming by filling of the venous line and the arterial line with priming fluid via a feed line, said priming liquid from said feed line flowing via the venous and arterial lines through the ports into the chamber, the chamber being empty at the start of the priming; and circulating the priming liquid in the circuit of the venous and arterial lines, the dialyzer and the chamber via a pump so that one of the ports of the chamber acts as an inlet and the other as an outlet. 2. The method in accordance with claim 1, wherein the consumed priming liquid in the blood tubing set is replaced after circulation by refilling fresh priming liquid from the feed line into the venous line and into the arterial line, with the consumed priming liquid flowing through the ports into the chamber. 3. The method in accordance with claim 1, wherein, on filling or refilling, the priming liquid is added downstream of a pump in one of the lines via the feed line. 4. The method in accordance with claim 1, wherein the two ports of the chamber can each be opened and closed via valves. 5. The method in accordance with claim 1, wherein the arterial line is first filled with the pump switched off and the venous line, having the pump thereon, is thereupon filled by operating the pump. 6. The method in accordance with claim 5, wherein a valve which is arranged at the inlet which is connected to the connection of the arterial line at the patient side is closed to fill the venous line via the pump. 7. The method in accordance with claim 1, wherein the feed line has a first end coupled to a priming fluid source and a second end coupled to the circuit, the feed line having a feed line pump located between the priming fluid source and the circuit, both the arterial line and the venous line being filled in parallel as priming liquid runs out of the priming fluid source and into the feed line pump which pumps the priming fluid into the arterial and venous lines. 8. The method in accordance with claim 1, wherein the feed line can be opened or closed via a valve. 9. The method in accordance with claim 1, wherein the priming liquid is pumped through the feed line via a feed line pump located downstream of a priming fluid source. 10. The method in accordance with claim 1, wherein the feed line is in communication with a second chamber of a second bag containing priming liquid. 11. The method in accordance with claim 1, wherein the feed line is in communication with a substituate port. 12. The method in accordance with claim 1, wherein a bag and a blood tubing set are used which are at least partly pre-connected and are sterilized in their totality. 13. The method in accordance with claim 1, wherein said bag has only one chamber. 14. The method in accordance with claim 1, further comprising the steps: connecting the bag with the empty chamber to at least one of said venous and arterial lines; and performing common sterilization of the bag and said at least one line. 15. The method in accordance with claim 14, wherein the common sterilization of the bag and said at least one line takes place via a sterilization fluid. 16. The method in accordance with claim 14, wherein the common sterilization of the bag and at least one line takes place with ethylene oxide (ETO). 17. A method for priming a blood tubing set having a patient side and a filter side and at least one pump, said blood tubing set including a venous line and an arterial line each having a connection at the patient side and a connection at the filter side, said connections of the venous and arterial lines at the patient side being in communication with two separate ports of a chamber of a bag and said connections of the venous and arterial lines at the filter side being in communication with a dialyzer, said venous and arterial lines, said dialyzer and said chamber forming a circuit, said method comprising the steps of: starting the priming by filling the arterial line with priming fluid via a feed line while the pump is turned off, said priming fluid from said arterial line entering the chamber through a first one of said two ports; closing a valve which is arranged at said first one of the ports to fill the venous line by operating the pump, said priming liquid from said venous line entering the chamber through a second one of the said two ports; and circulating the priming liquid in the circuit of the venous and arterial lines, the dialyzer and the chamber via the pump so that one of the two ports of the chamber acts as an inlet and the other as an outlet.
