    摘要: A monitoring device (7) operates on a pressure signal from a blood processing apparatus, e.g. a dialysis machine, which has an extracorporeal blood circuit connected to a vascular system of a subject for pumping blood through a dialyzer, and a treatment fluid supply system for pumping a treatment fluid through the dialyzer. The monitoring device (7) has a first input block (50) for obtaining a first pressure signal (y) from a first pressure sensor (6a) in the extracorporeal blood circuit, and a second input block (51) for obtaining a second pressure signal (w) from a second pressure sensor (6b) in the treatment fluid supply system. An emulation block (56) generates, as a function of the second pressure signal (w), an emulated first pressure signal (y) which emulates a concurrent signal response of the first pressure sensor (6a), and a filtering block (53) generates a filtered signal (y) as a function of the first pressure signal (y) and the emulated first pressure signal (y), so as to suppress, in the filtered signal (}y) compared to the first pressure signal (y), signal interferences originating from the treatment fluid supply system (lb). A pulse detection block (54) processes the filtered signal (y
    f ) for detection of subject pulses originating from the subject.

    摘要: A proposed blood treatment apparatus includes: a blood treatment unit (D), a pair of fluid pumps (PF1, PF2) and a pair of blood pumps (PB1, PB2). The blood treatment unit (D) is configured to receive untreated blood and fresh blood treatment fluid, and emit treated blood and used blood treatment fluid. The fluid pumps (PF1, PF2) are configured to pass blood treatment fluid through the blood treatment unit (D). The blood pumps (PB1, PB2) are configured to extract untreated blood from a blood source ( BS), pass extracted blood through the blood treatment unit (D) and deliver treated blood to a target vessel (BT). Flow measurement means (Q1, Q2, P) determines at least one blood f low parameter ( BQFI) reflecting an average flow in relation to the blood treatment unit (D) during a well-defined period of operation (T) of the apparatus, for example while completing one operation cycle. The at least one blood flow parameter (BQFI) is determined based on a difference between (i) a first amount (DMI) of fresh blood treatment fluid received into the blood treatment unit (D), and (ii) a second amount (DMO) of used blood treatment fluid emitted from the blood treatment unit (D) during another well-defined period (T
    a ).

    摘要: A monitoring device (7) operates an input block (30) to acquire a pressure signal from a pressure sensor (6a-6c) in an apparatus for extracorporeal blood processing connected to the vascular system of the subject. A processing block (34) repeatedly processes the pressure signal for generation of a time-sequence of parameter values indicative of pressure pulsations originating from heartbeats in the subject, and an evaluation block (35) evaluates the parameter values for detection of cardiac arrest and, if cardiac arrest is detected, generates a dedicated alarm signal. To reduce the risk for false positives without increasing the risk for false negatives, the monitoring device (7) may acquire and process more than one pressure signal, and/or perform an initial viability check before the monitoring is initiated to ensure that pressure pulsations originating from heartbeats are detectable in the pressure signal(s), and/or separate the monitoring of the pressure signal(s) into a detection phase performed during regular operation of a blood pump in the apparatus, and a verification phase performed during a temporary shutdown of the blood pump.
