Abstract
A control system is configured to implement a method of preparing a blood treatment apparatus (1) for blood treatment. The method comprises installing, by use of a disposable arrangement, first and second flow circuits (C1, C2) separated by a semi-permeable membrane (25), the first flow circuit (C1) being connected for fluid communication with the apparatus (1) and the second flow circuit (C2) being connected to form a closed loop that includes a sterilizing filter (46) and, optionally, a container (30). The method further comprises performing backfiltration to transfer a human-compatible fluid from the first flow circuit (C1) to the second flow circuit (C2) through the semi-permeable membrane (25), and circulating (304) the human-compatible fluid in the closed loop of second flow circuit (C2), to thereby sterilize the human-compatible fluid by the sterilizing filter (46) and, optionally, collect a resulting sterile fluid in the container (30) for later use.
