That is, the interlocking block 9 determines whether a predetermined value for the alternating magnetic field has been exceeded at any of the N points of the patient's treatment area by the signal from the block 7 recorded in the recording block 8. If it is exceeded, ie if it affects the completion of the program during the treatment time, an occlusion signal is provided to the occlusion input terminal of the magnetic therapy device 10. In accordance with the application of this occlusion signal, the magnetic therapy device 10, which generates a magnetic field at the treatment site of the patient, is switched off;
