摘要：A surveillance device (25) monitors the integrity of a fluid connection (C)between first and second fluid containing systems (S1, S2) based on at least one time-dependent measurement signal from a pressure sensor (4a-4c) in the first fluidcontaining system (S1). The first fluid containing system (S1) comprises a first pulsegenerator (3), and the second fluid containing system (S2) comprises a second pulsegenerator (3'). The pressure sensor (4a-4c) is arranged to detect first pulses originatingfrom the first pulse generator (3) and second pulses originating from the second pulsegenerator (3'). The integrity of the fluid connection (C) is determined based on thepresence of second pulses in the measurement signal. The second pulses may bedetected by analysing the measurement signal in the time domain and/or by using timinginformation indicative of the timing of the second pulses in said at least one
measurement signal. The analysis may be based on a parameter value that represents adistribution of signal values within a time window of the measurement signal. Forexample, the parameter value may be calculated as a statistical dispersion measure of
the signal values, or may result from a matching of the signal values within the timewindow to a predicted temporal signal profile of a second pulse. The fluid connection (C)may be established between a human blood system and an extracorporeal blood flowcircuit, e.g. for extracorporeal blood treatment.
