Interference flow production system for electro therapy - has electrode pairs with outputs to produce flow with phase angle adjustable by phase shift device

摘要

The device produces of interference flows for electrotherapy at a selected site on a human body, in partic. there are two different impulse or alternating flows which are fed to electrode pairs attached to the body so that the current from them intersect at the required location. Both the current flows are produced by a single oscillator and are of equal frequency. At least one (4, 5) of the electrode pairs (6, 7; 8, 9) outputs (2, 3; 4, 5) of the device produces a current flow which has a rhythmically adjustable place angle with a phase shift device (15-19).
