Microwave is the frequency of 300MHz-300GHz electromagnetic waves, is a limited band of radio waves in the short, that is, the wavelength of 1 meter (excluding 1 meter) to 1 millimeter between the electromagnetic waves, is a sub-meter wave, centimeter wave, millimeter wave of the collective term. Microwave frequency is higher than the general frequency of radio waves, usually also known as "ultra-high frequency electromagnetic waves". Microwave as a kind of electromagnetic wave also has wave-particle duality. Microwave quantum energy of 1 99 × l0 -25 ~ 1.99 × 10-22j.
In the 1930s of this century, medical workers discovered the biological effects of microwaves. In clinical practice, the interaction between microwaves and living organisms can be divided into two categories, namely, microwave thermogenic effect and non-microwave thermogenic effect. The microwave thermotherapy used in microwave therapeutic instruments is a non-contact heating method, and there is no possibility of thermal or electrical burns caused by electrical contact.
Microwave therapy has been used for many years in international and domestic applications, and its therapeutic effects have been recognized by the world medical community. At the time of surgery with its superior hemostatic effect, advanced principle of action, small tissue damage, and is likened to replace the electrocautery, freezing, laser new technology. Microwave therapeutic instrument is a new type of medical instrument that utilizes microwave to treat various diseases. In addition to the characteristics of deep heating, it also has the advantages of convenient operation, accurate positioning, high safety and low cost, compact structure of the instrument and wide adaptability. By equipping different accessory equipment, it can treat a variety of diseases.
The application principle of microwave therapy instrument
Microwave multi-functional therapeutic instrument utilizes the thermal effect of microwave biological tissues, hemostasis, coagulation, cauterization or anti-inflammation of diseased tissues, swelling, pain relief, and improvement of local tissue blood circulation, etc., to achieve the role of treatment of diseases.
The main indications of microwave therapy instrument
1, microwave physiotherapy: for chronic rheumatoid arthritis, contusion, periarthritis, sciatica, neuritis, localized suppurative tissues, etc.;
2, microwave surgery: for gastrointestinal polyps, prostate hyperplasia, cervical erosion, warts and so on.
The safety of microwave therapy instrument
One of the use to comply with the requirements of the instruction manual:
Microwave therapy belongs to the category of heat therapy, in the case of effective prevention of over-power output, the use of microwave therapy instrument as long as based on the requirements of the instruction manual is a very safe physical therapy equipment, if not in the hospital operated by the doctor to use, but the use of home microwave therapy instrument for their own operation, then the main attention in the process of use is as follows Then use the process of the main attention to the following matters:
(1) choose the power The size of the power used to warm comfort shall prevail, too high or too low power should be avoided, too high power of the hidden danger of scalding of the tissue to be treated;
(2) heat insensitive people should be used with caution, to avoid the occurrence of microwave scald;
(3) can not be used to directly irradiate the microwave therapy a eyes;
(4) wear a pacemaker patients to stay away from microwave therapy instrument;
(5) there are metal parts of human tissue can not be directly irradiated with microwave therapy head to avoid microwave aggregation of over-power burns;
(6) pregnant women can not be directly irradiated with microwaves on the abdomen;
(7) men of childbearing age can not be used to irradiate their testicles microwave.
Two microwave band is safe electromagnetic waves
Microwave and light waves belong to the same electromagnetic waves, according to the size of its frequency can be, we can understand the size of its radiation hazards to the human body, the higher the frequency, the stronger the radiation capacity. People worry about electromagnetic radiation is actually ionizing radiation, common electromagnetic wave frequency from high to low, including: r-ray, x-ray, ultraviolet, can be light, infrared, far infrared, microwave, short-wave and radio waves, etc.; so the microwave frequency band of the human body less harmful than the visible light and the commonly used heat therapy instrument used in the far-infrared.
Microwave therapy instrument physiotherapy features
(1) the efficacy of exact:
The efficacy of microwave on inflammation is based on the attributes of its thermal therapy instrument, is reflected through the thermal and biological effects of microwave, human tissue is rich in water molecules of the organization, so in the microwave therapy instrument irradiation, the improvement of its blood circulation is determined, and the degree of improvement to be far better than the traditional infrared-based physical therapy instrument. Infrared-based physical therapy instrument, so the efficacy is very certain.
(2) Fast effect
Acute inflammation can show the effect in 1 time, including the reduction of inflammation, redness, swelling and pain, etc.; Chronic inflammation can receive the effect of symptomatic improvement in 1-3 times, but in order to achieve the satisfactory effect, it is necessary to insist on the physical therapy for 1-4 weeks in order to rehabilitate the damaged cells and the function of human body tissues.
Microwave therapy instrument treatment principle
Why can microwave treatment of disease? Bioelectromagnetism as an emerging fringe discipline, has been more and more by domestic and foreign experts and scholars concerned about the importance of. In recent years, the study of high-frequency electromagnetic waves has been expanded to the millimeter wave band, and is regarded as the focus of research. Millimeter wave biomedical engineering research, began in the sixties, in 1968, Canadian scholars Webb published the first millimeter wave can inhibit the growth of bacteria biological effects of the article, and then he reported the existence of microorganisms on the millimeter wave similar to the resonance of the resonance of the energy absorption point, pointing out that the normal cells and cancer cells on the millimeter wave has a different absorption of resonance point. Since then, many scientists from Russia, the United States, Germany, France and China have done a lot of basic experimental research and clinical validation work. The results show that low energy density of millimeter wave irradiation can cause obvious biological effects, and at the same time in the millimeter wave clinical application has accumulated a lot of valuable information.
Microwave as a kind of millimeter wave, in addition to millimeter wave **** have characteristics, there are some differences in other millimeter wave unique properties. The main characteristics of microwaves are its light-like, penetrating and non-ionizing properties.
Light-like - microwaves, compared with lower frequency radio waves, more light-like propagation and concentration;
Penetrating - compared with infrared, microwaves irradiate the medium is easier to penetrate deeper into the material;
< p>Non-ionizing - the quantum energy of microwaves does not change the internal structure of the molecules of matter when interacting with it (only its state of motion). Short-wave ultrashort wave is the same electromagnetic wave, but compared with microwave, due to the substantial reduction in frequency, the clinical effect is very different. Human blood, lymph fluid, cerebrospinal fluid, etc. have special absorption effect on microwave. Such as short-wave ultrashort wave in the role of electrodes, fat and muscle temperature rise ratio of about 9 to 1, while the human body has a layer of fat under the skin, fat absorption of electromagnetic energy heat production is too much, is bound to hinder the role of electromagnetic energy in the deep tissues. The microwave effect on the human body fat and muscle heat production ratio is close to 1 to 1, so the microwave thermal effect is more uniform, in the deeper parts of the muscle layer is still a significant thermal effect.
Microwave biology clinical treatment mechanism microwave thermal effect of human tissue is composed of a variety of organic and inorganic compounds, these substances can have different characteristics on the electrical, such as sodium, potassium, calcium, iodine, iron and other inorganic ions in the body, they are attracted to the microwave electromagnetic field suddenly, suddenly repelled, the formation of the direction of the electric field of vibration, vibration of ions rubbing each other, and and the surrounding medium The friction between the ions and the surrounding medium during the vibration generates heat. The human colloid tissue was not electrical, but some of the colloid particles adsorbed around the ions will also show electrical properties, the formation of electrically charged colloids, these substances in the microwave field also produces a similar friction and collision of ions under the action of the movement and generate heat. Human tissue in the muscle, fat, protein, viscera, blood, lymphatic fluid, etc. are dielectric on the electricity, they contain a lot of water. Water is a polar molecule, water molecules with the positive and negative electric role of the center of overlap, usually does not show electrical properties. In the microwave electromagnetic field water molecules polarized, water molecules in the positive and negative electric action center does not overlap. Formation of electricity in the electric dipole and according to the direction of the high-frequency field instantaneous field rearrangement, so that the occurrence of sharp rotation to produce frictional heat.
Microwave non-thermal effect microwave effect on human tissue in addition to the thermal effect there is also a non-thermal effect, such as human milk fat, red blood cells and other electrically charged particles in the microwave field under the action of the distribution of the power line along the bead-like, these phenomena do not cause heat under the intensity of the electric field can also occur, reflecting a specific therapeutic effect in clinical medicine, it is clear that this therapeutic effect has nothing to do with the thermal effect.
Therapeutic mechanism of a large number of scientific experiments show that, whether ions, charged colloids or dipoles in the microwave field vibration or rotary movement generated by the thermal effect, or charged particles in the microwave field under the non-thermal effect (electromagnetic oscillation effect), can change the physical and chemical reaction characteristics of human tissues to produce the clinical effect of treatment. Microwave physiotherapy is the microwave energy concentrated irradiation to the lesion tissue parts, absorbed by the body's soft tissue. Because microwave is a high frequency electromagnetic field, it can penetrate into the human body tissue, so this biological effect is not only limited to the epidermis of the human body, and in the irradiated all the tissues from the epidermis to the deep at the same time to produce the above biological effect of microwave, the performance of the local temperature of the tissues, resulting in the promotion of the body's blood circulation, enhance the metabolism, improve the immune function and improve the local nutrition, and so on, a series of biological effects
The characteristics of microwave therapy using high-frequency local radiation, in the smaller microwave power output conditions, can achieve the desired therapeutic effect. Microwave thermal effect on human tissue with high efficiency, strong penetration, with the advantages of internal and external heat generation at the same time. Microwaves generate heat in human tissues, the effect can reach 5 - 8 cm, can penetrate clothing and plaster and other body surface coverings, directly to the lesion site to promote blood circulation, water absorption and the growth of new granulation. Body surface type radiators are easy to position (all parts of the human body surface) and are not affected by the patient's sitting or lying down, thus making the use of the patient feel more comfortable and simpler to operate.
Applicable to a wide range of diseases, treatment of a variety of diseases, painless, non-invasive, no side effects and adverse reactions in the treatment, with anti-inflammatory, blood circulation, pain relief effect.
Microwave therapy does not require the removal of clothing can be treated, so even if the body's embarrassing parts of the treatment does not require it to avoid, can be lifted in the leisure and recreation of pain.
Microwave heat in the fat and muscle ratio close to 1 (short-wave and ultra-short-wave in the role of the electrode fat temperature rise and muscle temperature rise to the ratio of about 9 to 1), that is, the microwave thermal effect is more uniform, even in the deeper parts of the muscle layer is still a significant thermal effect. Thus, even if the deeper parts of the disease has been able to achieve a better therapeutic effect
Wish you a speedy recovery!
