Medium-Frequency Interference Electrotherapy Device (Vertical Type)

Working principle

Characteristics of Dynamic Interference Current

1. Three-dimensional stimulation effect
The superposition of three groups of intermediate-frequency sinusoidal currents within the human body generates a stereoscopic low-frequency electric field through beat frequency effects, thereby producing a three-dimensional spatial stimulation effect.

2. Stimulatory effect with no blind spots
Within the area enclosed by the six electrodes, the stimulation site has great depth and no blind spots.

3. Dynamism of Strength
With low-frequency modulation of the medium-frequency current in the three groups, the electric field strength within the human body can automatically vary within a certain range.

4. Dynamic changes in the stimulation of the Fufu area
It can alter the magnitude, direction, angle, and shape of interference fields within the body.

Therapeutic effects of dynamic interference current

From the monograph "Electrotherapy and Phototherapy," the therapeutic effects of interference currents are summarized as follows:
1. Analgesic effect, with a significant increase in skin pain threshold;
2. Promotes local blood circulation; after treatment, the skin temperature of most patients increases. In patients with obliterative endarteritis, arterial waveform changes improve following treatment, and intermittent claudication shows significant improvement as well.
3. It has a superior effect on motor nerves and skeletal muscles compared to low-frequency pulsed current therapy; at the same current intensity, it elicits a greater degree of dorsiflexion of the foot.
4. It improves the tone of gastrointestinal smooth muscle, enhances blood circulation in the viscera, and regulates the autonomic nerves that innervate the internal organs. This is because at the stereoscopic intersection point, the frequency remains in the medium range, and tissue resistance is relatively low, allowing the current to penetrate deeply into the tissues without significant attenuation. As a result, electrical stimulation can be effectively delivered within the body, giving this therapy a significant advantage in treating visceral disorders characterized by insufficient gastrointestinal smooth muscle tone, such as visceral prolapse and chronic constipation.
5. Regarding its regulatory effect on the autonomic nervous system, stimulation of sympathetic ganglia does indeed exert a certain regulatory influence on the autonomic nervous system. Applying interference current therapy to the stellate ganglion in hypertensive patients can help reduce either systolic or diastolic blood pressure.

Performance Features

• Stereoscopic Dynamic Interference Current: Stereoscopic dynamic interference current is the latest variant of interference current. Compared to traditional interference current, which operates only in the two dimensions of X and Y, stereoscopic dynamic interference current acts in all three spatial dimensions—X, Y, and Z—hence its name “stereoscopic interference current.” The “dynamic” aspect refers to a low-frequency pulsation induced in the interference current through electrical means, causing the current intensity to vary dynamically.
• A total of 16 treatment modes are available: The device carefully selects the optimal combination of frequency and current, which is stored in the main unit. The treatment prescription is displayed directly on the panel for easy and clear selection. Physicians can also customize treatment plans according to the patient’s specific condition: They can choose their own treatment procedures, and the main unit will automatically carry out the entire treatment process based on the selected program. With up to 16 customizable treatment modes, this approach offers greater clinical precision and significantly enhances therapeutic efficacy.
• Pursuit of Reliability and Patient Comfort: The company has paid close attention to the instrument’s anti-interference capabilities and overall reliability, successfully overcoming the brief electric shock sensations that patients might experience during treatment due to external disturbances. To ensure patient comfort throughout the treatment process, we have incorporated several more user-friendly design features, with particular emphasis on smoothly transitioning between different treatment modes—making these transitions gentle and easily acceptable for patients.
