摘要： A surveillance device (25) monitors the integrity of a fluid connection (C) between first and second fluid containing systems (S 1, S2) based on at least one time-dependent measurement signal from a pressure sensor (4a-4c) in the first fluid containing system (Sl). The first fluid containing system (Sl) comprises a first pulse generator (3), and the second fluid containing system (S2) comprises a second pulse generator (3 '). The pressure sensor (4a-4c) is arranged to detect first pulses originating from the first pulse generator (3) and second pulses originating from the second pulse generator (3 '). The integrity of the fluid connection (C) is determined based on the presence of second pulses in the measurement signal. The second pulses may be detected by analysing the measurement signal in the time domain and/or by using timing information 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 a distribution of signal values within a time window of the measurement signal. For example, 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 time window 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 flow circuit, e.g. for extracorporeal blood treatment.

摘要： A device is provided for monitoring the integrity of a flow circuit in fluid communication with a receptacle. The flow circuit comprises a pumping device for transferring fluid through the flow circuit. The device operates according to a monitoring method in which a pressure signal is received (401) from a pressure sensor, the pressure signal being indicative of fluid pressure in the receptacle or the flow circuit. The pressure signal is then processed (406-407) for detection of a beating signal. The beating signal manifests itself as an amplitude modulation of the pressure signal and is formed by interference between pressure waves generated by a pulse generator associated with the receptacle and pressure waves generated by the pumping device. The integrity of the flow circuit is determined (408-409) based at least partly on the presence or absence of the beating signal. The device and the flow circuit may be part of an apparatus for extracorporeal blood treatment, and the method may be implemented as a computer program product.

摘要： It is an object of the invention to provide a method and a device for monitoring the integrity of a flow circuit using a pressure measurement. The device comprises an input for a pressure signal, the pressure signal being indicative of fluid pressure in a receptacle, and a signal processor configured to process the pressure signal for detection of a beating signal formed by interference between pressure waves generated by a pulse generator associated with the receptacle and pressure waves generated by a pumping device (3).
