Magnetic field applicator with a ramp-shaped waveform of the coil currents used

摘要

Magnetic field applicator (1, 55) with a ramp-shaped waveform of the coil currents used (10, 37, 44, 49), consisting of low-frequency, in amplitude ramped basic pulses (10, 37) of the coil current, which act during a defined treatment time (11) which are part of pulse packets (44) composed of the basic pulses (10, 37) whose envelope (17, 17a, 17b) described by the amplitudes of the basic pulses (10, 37) is also ramp-shaped, the envelope (17, a, 17b, 17c) of the amplitudes of the fundamental pulses (10, 37) forms a rising from zero near rising cam branch (57) which rises approximately to the middle of a treatment time (11) and thereafter until the end of the treatment time (11) corresponding to the maximum current strength, constant curve load (58) is formed, (Fig. 13-15).
