Abstract
An output controller for low-frequency treatment device for use in a bath, comprising a low-frequency oscillator; a variable water resistor having fixed terminals connected with the output terminal of the low-frequency oscillator; and an active electrode connected with the sliding terminal of the variable water resistor.
Claims3
A variable water resistor for controlling the application of a therapeutic voltage to a human body, comprising:
- two fixed electrodes provided at a predetermined interval, said fixed electrodes being connected with an output terminal of a low-frequency oscillator that generates said therapeutic voltage;
- a sliding electrode slidable along with said fixed electrodes, said sliding electrode being connected with a therapeutic electrode that is placed on the skin of the human body during therapy;
- and
- said fixed electrodes and sliding electrode being soaked in water to form a variable water resistor when in use.
