<P>PROBLEM TO BE SOLVED: To provide a living body stimulating apparatus that prevents distortion of the pulse waveform of a stimulation signal by surely separating a low-frequency pulse output circuit from a high-voltage pulse output circuit while simplifying a circuit arrangement. <P>SOLUTION: An electrode 31 is brought into contact with a living body and a high-voltage pulse generated by a second output circuit 9 is superimposed on a low-frequency pulse generated by a first output circuit 8 to provide a stimulation signal to the living body from the electrode probe 31. Constant-voltage semiconductor elements 32, 33 are provided as coupling means which do not conduct even at the generation of the low-frequency pulse from the first output circuit 8 to separate the first output circuit 8 from the second output circuit 9, and which couple the first output circuit 8 and the second output circuit 9 together only when a high-voltage pulse is generated from the second output circuit 9 and reaches a blocking voltage or higher. <P>COPYRIGHT: (C)2012,JPO&INPIT |
