Abstract
A first connector of a connector assembly of a sterile batch container can be unsealed. The connector assembly can be attached to a filling port of the sterile batch container and can have a sterile filter arranged between the filling port and the first connector. The first connector can be coupled so as to receive produced purified water. A transmembrane pressure can be monitored across the sterile filter while flowing the purified water through the connector assembly into the sterile batch container so as to provide a sterile fluid stored therein. The connector assembly can be detached from the filling port of the sterile batch container. After the detaching, the sterile batch container can be coupled to the blood treatment system. In response to a change in the transmembrane pressure exceeding a predefined level, an alarm signal can be generated.
