Abstract: A blood filtering machine (1) having a blood circuit (2), which has a plurality of ducts (5a-5c) made of a transparent material, and a measuring system (7), which has a plurality of optical sensors (8a-8c) coupled to respective ducts (5a- 5c). Each optical sensor (8a-8c) has a reading window (10) placed in a point of the respective duct (5a-5c), a light emitter (11) and a light receiver (12). The measuring system (7) comprises one single spectrometer (14), an optical mixer (13) comprising a plurality of inputs, each connected to the light receiver (12) of a respective one of the optical sensors (8a-8c), and an output, which is connected to an input of the spectrometer (14), and a control unit (17) is configured to activate the light emitter (11) of one optical sensor (8a-8c) at a time so as to measure a parameter of one organic fluid at a time.
