PROBLEM TO BE SOLVED: To attain interference low-frequency stimulation with high therapeutic effect hardly causing insensitiveness to stimulation, using few electrodes by generating a plurality of interference low-frequency to perform complicated biological stimulation.SOLUTION: The interference low-frequency therapeutic apparatus includes a plurality of series of output parts having a carrier wave generation part to generate a carrier wave with frequency f, a therapeutic wave generation part to generate a therapeutic wave, a convertor to change a phase or frequency of the carrier wave generated at the carrier wave generation part within a prescribed range, an adder to add the output of the carrier wave generation part and the output of the convertor to output interference low-frequency, and an amplifier to amplify the output of the adder to a desired value. The outputs of the output parts in the plurality of series of output parts can be simultaneously supplied to a living body.COPYRIGHT: (C)2012,JPO&INPIT【課題】複数の干渉低周波を発生し、複雑な生体刺激をおこなうことで、慣れの少ない、治療効果の高い干渉低周波刺激を、少ない電極で実現する。【解決手段】周波数がfの搬送波を発生する搬送波発生部と、治療波を発生する治療は発生部と、前記搬送波発生部で発生させた搬送波の位相又は周波数を所定の範囲で変化させる変換器と、前記搬送波発生部の出力と前記変換器の出力を加算し干渉低周波を出力する加算器と、前記加算器の出力を所望の値に増幅する増幅器と、を有する出力部を複数系統、設け、前記複数系統の出力部の出力を同時に生体に供給するようにした。【選択図】図1
