Unfortunately, the affected hose system was not available anymore at customer site so that it could not be provided for investigation.Therefore, a case-specific evaluation was not possible and the root cause for the reported disconnection could not be determined.As the affected connection between tube and y-piece is a plug connection the ifu describes as a warning that before use it has to be confirmed that all connections are secure and free of leakages.In line with this pre-use check a loose plug connection is detected and can be reconnected properly.If a relevant leakage occurs due to a loose connection, it will be detected during the leak-test that must be performed prior to each patient use.In case a relevant leakage suddenly occurs during use, corresponding alarms will be given.
