Abstract

PURPOSE:To execute the medical treatment of the separated part of the human body by connecting an external electrode to an output circuit instead of one electrode, when a connecting cord is installed. CONSTITUTION:A jack 5 of a low frequency medical treatment device 1 is provided between one electrode 4b of a pair of electrodes 4a, 4b, and a polarity switching circuit 10b being an output circuit for outputting a low frequency pulse to this one electrode 3b. As for this jack 5, when a plug 7 of an external electrode 6 is inserted, one electrode 4b is not connected to the polarity switching circuit 10b. This jack is constitute so that when the plug 7 of the external electrode 6 is inserted, the external electrode 6 is connected to the polarity switching circuit 10b instead of one electrode 4b. In such a way, by impressing low frequency pulses of different polarity to each electrode 4a, 4b, a current comes to flow between a pair of both electrodes 4a, 4b, and the medical treatment is executed thereby.
