Device for blood flow property measurement and method of its connection

A device for blood flow property measurement comprising:

• three current generators (1);
• at least twelve scanning channels (5);
• at least six current electrodes (9);
• at least three reference-frequency links (4);
• a control and processing block (10);
• and
• a data link (14) connected to at least one member of the group consisting of a personal computer (PC), a computer network, a computer network and display (15), and a display (15);
• and
• a control board (11),
• wherein each current generator (1) contains an alternating-current source (2) and a harmonic-signal generator (3) linked to the alternating-current source (2),
• wherein each scanning channel (5) contains an amplifier (8), a detector (7) and at least two voltage electrodes (6), two of the at least six current electrodes (9) are attached to each alternating-current source (2),
• wherein each harmonic-signal generator (3) is connected to at least four scanning channels (5) by means of a reference-frequency link (4) through a detector (7) which is connected to an amplifier (8),
• wherein each amplifier (8) has two of the voltage electrodes (6) connected to thereto,
• wherein each harmonic-signal generator (3) and each detector (7) is connected to the control and processing block (10) to which additional outputs are attached,
• wherein the data link (14) is connected to at least one member of the group consisting of a personal computer (PC), a computer network, a computer network and display (15), and a display (15) and further connected to the control board (11);
• and
• wherein the current generators (3) have reference frequency values differing from one another by about 1 Khz.
