Abstract:
1. A method for the filling and flushing of a blood tubing set with a substituate, the blood tubing set including a pump segment for a blood pump, an arterial line connected to an inlet of a dialyser, a venous line connected to an outlet of a dialyser, a substituate line connected to a substituate port and having a. pump segment for a substituate pump, and a three-way connector connected to the arterial line, the venous line and a rinse port, the method comprising the following steps: opening the rinse port; simultaneously filling the arterial line and the venous line and simultaneously flushing the arterial line and the venous line with the substituate, in that an amount m+n of substituate is supplied from the substituate pump via the substituate line to a suction-side line of the blood pump, the blood pump transports an amount n, drawn from the amount m+n of substituate supplied by the substitute pump, through either the arterial line or the venous line to the three-way connector and, simultaneously with the transport of the amount n, a remaining amount m of the amount m+n of substituate the substitute pump flows throuoh the other of the arterial line or the venous line to the three-way connector in another direction while an amount m+n of substituate is drained off via the rinse port; closing the rinse port; and circulating the substituate in the circuit of arterial line, dialyser and venous line by the blood pump.
