ABSTRACT:
A pair of magnets is adapted to be rotated into several positions around the periphery of a limb for the purpose of producing the magnetic field used in blood flow measurements. Electrodes are arranged in pairs located diametrically opposite each other on the limb. The blood flow measurements are obtained by sequentially monitoring each pair in the array of electrodes located on the skin of the limb so as to obtain blood flow measurements at a plurality of circumferential locations on the limb. Each measurement is stored in a memory, with the heartbeat providing the timing reference. The averaged contributions of each of the several arteries in the limb are picked up by the electrodes to provide a valid total measurement of the overall blood flow in the limb.
