摘要：
A monitoring device, comprising: a first input block (50) configured to obtain a first pressure signal (y) from a first pressure sensor (6a), which is arranged in an extracorporeal blood circuit (1a) to detect pressure variations in blood is pumped through a processing unit of blood (5) in the extracorporeal blood circuit (1a) by means of a blood pump (4), wherein the extracorporeal blood circuit (1a) is connected to a vascular system of a patient characterized by a second input block (51) configured to obtain a second pressure signal (u) from a second pressure sensor (6b), which is arranged in a feeding treatment fluid (1b) to detect variations pressure in a treatment fluid which is pumped through the blood processing unit (5) by the feed system treatment fluid (1b) emulation block (56) configured to generate, based on the second pressure signal (u), a first pressure signal Emulated (u) that emulates a response signal concurrent first pressure sensor (6a) a block filter (53) configured to generate a filtered signal (f) based on the first pressure signal (y), and the first signal emulated pressure (y), to remove from the filtered signal (f) compared to the first pressure signal (y), signal interference from the feed system treatment fluid (1b) and a block detection pulse (54) configured to process the filtered signal (yf) for detecting pulses of the patient from the patient.Un dispositivo de monitorización, que comprende: un primer bloque de entrada (50) configurado para obtener una primera señal de presión (y) desde un primer sensor de presión (6a), que está dispuesto en un circuito sanguíneo extracorpóreo (1a) para detectar variaciones de presión en sangre que es bombeada a través de una unidad de procesamiento de sangre (5) en el circuito sanguíneo extracorpóreo (1a) mediante un dispositivo de bombeo de sangre (4), en el que el circuito sanguíneo extracorpóreo (1a) está conectado a un sistema vascular de un paciente caracterizado por un segundo bloque de entrada
