PROBLEM TO BE SOLVED: To provide a low-frequency therapeutic apparatus having a plurality of electrodes capable of being switched freely which intelligibly informs a user where to treat.SOLUTION: The low-frequency therapeutic apparatus comprises a plurality of electrode pairs, a polarity switching circuit for switching the electrodes freely and for applying voltage between the electrodes by switching a voltage polarity arbitrarily, and a display section for displaying conducting state of electric current flowing through the electrodes. The display section has electrode patterns 31p, 32p, 41p and 42p representing the electrodes in a simulated fashion respectively and a conduction pattern section 60 with conducting patterns 61-66 showing the locations of the electrodes through which electric current flows, and turns on the patterns when electric current flows. With such a configuration, the location of the plurality of electrodes through which electric current flows becomes easy to recognize visually and the user can easily feel treatment effect. Effect of recognition by means of such a display is especially enhanced when the electrode pair through which electric current flows is not determined and is switched freely.COPYRIGHT: (C)2008,JPO&INPIT【課題】複数の導子を持ち導子間を切換え自在とする低周波治療器において、使用者に治療部位を分かり易く知らせる。【解決手段】低周波治療器は、複数の導子対と、各導子間を自在に切換え、これら導子間に電圧極性を任意に切り換えて印加する極性切換回路と、各導子間に流れる電流の通電状態を表示する表示部とを備える。表示部は、各導子を擬似的に示す導子部の導子パターン31p、32p、41p、42pと、実際に電流の流れている導子間の箇所を示す通電パターン部60の通電パターン61~66とを備え、通電時に各パターンを点灯する。これにより、複数の導子間に流れる電流箇所が視覚的に分かり易くなるので、使用者が治療効果をより実感し易くなる。特に、電流を流す対となる導子が決まった相手ではなく、自在に切替えられる場合は、より表示による認識効果が上がる。【選択図】図3
