Abstract
Изобретение относится к устройству и способу для распознавания крови или составляющих крови в жидкостной системе устройства для экстракорпоральной обработки крови, которое имеет разделенный с помощью полупроницаемой мембраны (2) на первую камеру (3) и вторую камеру (4) диализатор (1) или фильтр, при этом первая .камера (3) является частью экстракорпорального кровообращения (I), а вторая камера (4) является частью жидкостной системы (II). Устройство, согласно изобретению, для распознавания крови или составляющих крови в жидкостной системе устройства для экстракорпоральной обработки крови выполнено в виде устройства для различения попадания крови в жидкостную систему вследствие неисправности диализатора или фильтра, например разрыва полупроницаемой мембраны диализатора или фильтра, или попадания гемоглобина в жидкостную систему вследствие гемолиза, на основании изменения интенсивности по меньшей мере синей составляющей выходящего из жидкости света.
