PROBLEM TO BE SOLVED: To provide a living body stimulating apparatus capable of saving a cost and space of a product while achieving high-breakdown-voltage insulation by dispensing with a medical power supply.SOLUTION: When a secondary coil 4B of an output transformer 4 outputs a first stimulus signal to an electrode 5, the output transformer 4 electrically insulates between a main control circuit 2 and the electrode 5. The output transformer 4 connects the secondary coil 4B to a rectifying/smoothing circuit 11 by a switch 12 and, even when a second stimulus signal is output from an output control circuit 7 to the electrode 5, electrically insulates between the main control circuit 2 and the output control circuit or the electrode 5. The output transformer 4 that is preliminarily insulated is used as a transformer for an insulated power supply of the output control circuit 7 so as to dispense with the medical power supply required to have the high insulation. |
