LDG-2-A Type Stereodynamic Interferential Electrotherapy Apparatus

1000

Overview of the Stereo Dynamic LDG-2-A Interferential Therapy Device:

1. The Stereo Dynamic LDG-2-A Interferential Therapy Device uses two special star-shaped output cables and electrode pads to deliver three sets of medium-frequency sinusoidal currents with different frequencies into the body through cross-input. This creates a three-dimensional interference field within the body, generating low-frequency (beat frequency) rotary currents with significant therapeutic effects.

Simultaneously, the three currents are amplitude-modulated by a low-frequency triangular wave, resulting in dynamic stimulation effects across multiple areas, directions, angles, and shapes. During treatment with this current, the therapeutic effect is no longer due to a single medium-frequency current but rather a medium-frequency current containing low-frequency components.

Under each electrode, the medium-frequency current exerts its therapeutic effect, which the body adapts to easily and with minimal irritation. In the deep regions where the three currents intersect, various endogenous low-frequency rotary currents provide therapeutic benefits. Thus, stereo dynamic interferential current therapy effectively overcomes the limitation of low-frequency currents being unable to penetrate deep into tissues due to high skin resistance, offering combined medium and low-frequency therapeutic effects.

Characteristics of Stereo Dynamic Interferential Current:

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 strength distribution in the interference field can create 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.

Features and Functions of the Device:

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 treatment modes are designed to be smooth and patient-friendly;

b) The device is very easy to operate, with the entire treatment process fully 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 output value displayed on a dedicated screen;

d) Stereo dynamic interference display: Composed of a central light, circular lights, and light bars. The central and circular lights reflect the trend of the beat frequency (low-frequency rotary current). When the flashing of these lights speeds up, it indicates an increase in the beat frequency. The light bars display the dynamic rhythm of the amplitude of the three medium-frequency currents. The length of the light bars represents the variation in the amplitude of the modulated current, helping users adjust the current intensity under dynamic amplitude changes or induce active function in patients;

e) Accurate timing with six settings: 5min, 10min, 15min, 20min, 25min, and 30min, with an alert 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 removal and replacement;

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

Indications:

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