HY-D01 Medium Frequency Drug Introduction Therapy Apparatus

I. Huayi HY-D01 Computerized Intermediate Frequency Drug Introduction Therapy Apparatus (Four Channels) Functions

This therapy apparatus uses microcomputer control to generate intermediate frequency unidirectional pulse bio-therapeutic current. Based on the theory of drug ion introduction, under the action of electric field force, it causes directional movement of polar drug ions in the drug solution, pushing them wave by wave into the body through sweat gland ducts. Only the part of the drug that needs to exert pharmacological effects is introduced into the body. The charged drug ions introduced into the body gradually dissipate in the affected area and enter the blood and lymph, thereby producing a long-lasting systemic drug therapeutic effect to achieve the goal of curing various diseases.

While completing the above drug ion introduction administration method, it also performs physical therapy on the human body with three physical frequency bands of current: intermediate frequency, low frequency, and direct current. This allows the charged drug ions to exert pharmacological effects while also stimulating sensory nerve endings in the skin, causing vascular dilation through axonal reflex and other unique neurohumoral reflex functions, especially vegetative nerve reflex effects. Such a combination design enables this instrument to leverage the inherent properties of intermediate frequency current, significantly reducing tissue resistance through tissue capacitance, allowing the therapeutic effect to reach deeper parts of the human body. It exerts anti-inflammatory, anti-swelling, significant analgesic, pain-relieving, and vascular function regulatory effects, while also utilizing low-frequency current to stimulate nerves, promote good muscle contraction, dilate blood vessels, improve peripheral blood circulation, enhance human metabolism, improve neuromuscular nutrition, promote nerve regeneration and functional recovery, prevent muscle atrophy, and enhance the absorption function of pathological products. Moreover, the above functions are not simply additive but work synergistically to exert comprehensive therapeutic effects of various therapies.

The HY-D01 therapy apparatus acts on the affected area to dilate blood vessels and promote blood circulation. Methods such as plethysmography and infrared imaging have proven that after treatment, local blood circulation increases by about 141%, lasting for more than 40 minutes, and skin temperature can rise by 0.3–0.5°C. It has extremely significant effects in changing cell membrane permeability, improving local nutrition and metabolism, unblocking meridians and blood vessels, and promoting blood circulation to remove blood stasis. Using this apparatus greatly influences tissue water content: under the cathode, water content increases, proteins easily absorb water and disperse, expand, and become soft, significantly accelerating the removal of metabolic products. Therefore, it has obvious effects in eliminating various types of inflammation, softening scars, loosening adhesions, and relieving pain. Under the anode, it has a significant dehydrating effect, eliminating local tissue swelling or drying lesions with excessive exudate. Especially when introducing relevant drugs symptomatically, it shows significant therapeutic effects for diseases such as hyperosteogeny, rheumatism, cervical spondylosis, arthritis, periarthritis of the shoulder, hemiplegia, lumbar disc herniation, sprains, and strains.

II. Overview

This instrument is a new generation computerized intermediate frequency drug introduction therapy apparatus developed by Beijing Huayi New Technology Research Institute based on a careful summary of similar domestic and international instruments, years of clinical practice by renowned experts, and the unique advantages of modern computer high-tech. It is a modern high-tech medical instrument product that combines traditional Chinese medicine with Western medicine and microcomputer electronic technology.

Extensive social and objective clinical practice has proven that some drug introduction instruments currently used in clinical settings in some hospitals have urgent issues that need to be addressed. For example, the use of intermediate frequency bidirectional current for so-called "drug ion introduction" (intermediate frequency electric fields change positive and negative polarity at a rate of over 1000 times per second, while drug ions have clear positive and negative polarity. How can drug ions produce directional movement (into the body) in such a high-speed alternating polarity electric field?). This situation has serious defects both in terms of ion introduction basic theory and electronic technology design. Other instruments are simply constructed with basic hardware and use unprocessed DC electric fields for ion introduction, ignoring the objective fact of the existence of "polarization electric fields" in their design. In clinical treatment, just 1 millisecond after turning on the DC current, the current intensity drops sharply to 10%–1% of the initial level, and the longer the通电 time, the greater the polarization electric field (because the current direction of the polarization electric field is opposite to that of the applied electric field, canceling each other out), resulting in poorer therapeutic effects and a high risk of medical accidents such as burns to patients. Therefore, as a designated manufacturer engaged in professional ion introduction technology research and medical instrument production, we solemnly introduce to society the new generation HY-D01 computerized intermediate frequency drug introduction therapy apparatus (four channels), which combines 21st-century high-tech electronics with modern medicine.
