Cartridge device for blood analysis

Cartridge device (20) for analyzing blood comprising: a cell (9) having a receiving portion of blood (10) for receiving a blood sample and a receiving portion of pin or socket (12) for housing a pin or a socket (22); means (19) for circulating said blood sample within said blood receiving portion (10); and an electrode holder (14) having at least one pair of metal wires (16; 24; 25; 26) incorporated; wherein the electrode holder (14) is coupled to the cell (9) such that one end (16a; 24th, 25th, 26a) of at least one pair of wires (16; 24; 25; 26) is positioned within the receiving portion of blood (10) and forms a sensor unit (17a; 17b; 17c; 17d) for measuring the electrical impedance between the two electrodes of at least one pair of wires (16; 24; 25; 26) in a blood sample and the opposite end (16b; 24b; 25b; 26b) of at least one pair of wires (16; 24; 25; 26) is positioned within the receiving portion of pin or socket (12) and form a portion of pin or socket (21a, 21b, 21c, 21d) which can be connected directly to a pin or socket (22) for electrical connection of the sensor unit (17a, 17b, 17c, 17d) to analyze Zador.
