Low-frequency electrotherapeutic device
First Claim
1. In a low-frequency electrotherapeutic device which comprises an oscillator capable of generating a low-frequency voltage and a pair of electrodes connected to an output terminal of said oscillator, the low-frequency voltage being applied to a human body through said pair of electrodes, the improvement wherein said low-frequency voltage has a ratio of positive voltage component to negative voltage component in the range of about 0.1:
- 1-0.5;
1 and in the low-frequency voltage its reverse energy is larger than forward energy thereof.

Abstract
A novel low-frequency electrotherapeutic device wherein a low-frequency voltage having a ratio of positive voltage component to negative voltage component in the range of about 0.1:1-0.5:1 is used. The electrotherapeutic device can be advantageously used to massage human body or to iontophorese medicament thereinto without causing unwanted discomforts such as pain, inflammation and burning which are inevitable in conventional low-frequency electrotherapy.
