LDG-2-A Stereodynamic Interferential Electrotherapy Apparatus

Yaoyangkangda LDG-2-A Stereodynamic Interferential Electrotherapy Device Overview

1. Through two special star-shaped output cables and electrode pads, three sets of medium-frequency sinusoidal currents with different frequencies are cross-input into the human body, forming a three-dimensional interference field within. This generates low-frequency (difference frequency) rotational currents with significant therapeutic effects.

Simultaneously, the three currents are amplitude-modulated by low-frequency triangular waves, achieving dynamic stimulation effects across multiple areas, directions, angles, and shapes. During treatment with this current, the therapeutic effect is no longer from a single medium-frequency current but from a medium-frequency current containing low-frequency components. Under each electrode, the medium-frequency current exerts its therapeutic effect with easy adaptation and minimal stimulation. In the deep regions where the three currents intersect, various endogenous low-frequency rotational currents provide therapeutic benefits. Thus, stereodynamic interferential current therapy effectively overcomes the limitation of low-frequency currents being unable to penetrate deep tissues due to high skin resistance, combining the comprehensive therapeutic effects of both medium and low frequencies.

Yaoyangkangda LDG-2-A Stereodynamic Interferential Electrotherapy Device Features:

① Spatial stimulation effect: Provides stimulation in a three-dimensional space;

② Multi-site stimulation effect: Within the area enclosed by the electrodes, the electric field intensity distribution in the interference field can generate multiple stimulation sites;

③ Enhanced dynamic effect: The addition of low-frequency intensity variations to the medium-frequency current produces a dynamic effect;

④ Dynamic changes in stimulation sites: The frequency of the endogenous low-frequency current changes under computer control, altering the electric field distribution and thus the stimulation sites.

Instrument Features and Functions

a)  Six treatment protocols are stored in the computer chip, displayed on the panel, and scroll-selectable. During the 30-minute treatment for each protocol, the frequency and output current undergo 12 variations, totaling 72 variations across all six protocols. Transitions between different treatment modes are designed to be smooth and patient-friendly;

b) The instrument is very easy to operate, with the entire treatment process controlled by the computer. After selecting the treatment protocol, adjusting the output current, and setting the treatment time, the device automatically completes the treatment;

c) The output current is continuously adjustable, with the comprehensive value displayed on the screen;

d) Stereodynamic interference display: Composed of a central light, circling lights, and light bars. The central and circling lights reflect the trend of the difference frequency (low-frequency rotational current). When the flashing speeds up, it indicates an increase in the difference frequency. The light bars display the dynamic rhythm of the amplitude of the three medium-frequency currents, with the length of the brightness indicating the amplitude variation of the modulated current, helping users adjust the current intensity under dynamic changes or induce active patient function;

e) Accurate timing with six settings: 5min, 10min, 15min, 20min, 25min, 30min, with an alarm at the end of treatment;

f) Three electrode pads can be inserted into the pins of the star-shaped electrode output cable, allowing for individual detachment and replacement;

g) Features a no-load display to detect poor contact in the output circuit or broken electrode wires during treatment.

Indications:

This electrotherapy device uses interferential currents to promote local blood circulation and relieve pain. It provides auxiliary treatment for neuromuscular disorders, arthritis, neuralgia, sprains, gastroptosis, and other conditions.
