Terahertz light wave refers to a very short wavelength of radio light wave, refers to the frequency in the range of 0.03THz to 0.3THz electromagnetic wave, the wavelength is about 900um to 900cm range, close to the wavelength of infrared energy. Terahertz light wave health treatment equipment uses the heat accumulation effect of terahertz light wave to irradiate the diseased parts of the human body, where water molecules vibrate and heat with the terahertz light wave field, accelerating blood circulation and tissue metabolism, and promoting the recovery of blood and nerve function.

In particular, it has a significant effect on inhibiting bacterial growth, anti-inflammation and detumescence.

It has a wide range of applications and remarkable efficacy, and satisfactory results have been achieved in the treatment of many patients.

Terahertz light wave health care therapeutic instrument uses terahertz light wave, its action depth on the human body is 3-5cm, after a certain time of local action,

the temperature of the depth of about 2cm can be increased to 40℃ to 50℃ or so, it produces a thermal effect of strong penetration, high efficiency, which is incomparable to infrared, short wave, ultra-short wave heat, Its penetrating power can pass through the fat layer to the muscle layer, so the use of Asia-Pacific Hertz light wave energy can promote blood circulation, anti-inflammation, pain relief, a variety of inflammation and rheumatism has significant effect.

2. The therapeutic instrument is small in size, light in weight and easy to operate. Different diseases can be treated by changing different probes (irradiator heads).

Power and time are controlled by single chip microcomputer, LED display, accurate timing and sound prompt function, which brings convenience to the operation of medical staff.

3, biophysical characteristics Terahertz light wave has some physical characteristics similar to light wave, such as beam propagation, with dispersion performance, in different media can cause reflection, refraction, diffraction, scattering, absorption and the use of reflector for aggregation, its law and the corresponding optical law close. Terahertz light waves are called irradiation. Because of the large dispersion of terahertz light waves, a special transmission system with coaxial cable and an irradiator head is used. Terahertz light waves are radiated wirelessly from the irradiator into space and act on the human body. When terahertz light waves irradiate the human body, part of the energy is absorbed, and the other part is reflected by the skin and various layers of tissues. The reflectivity of the irradiated body is 40 ~ 50%.

Water-rich tissues can absorb more THZ light energy, while fat and bone reflect a considerable part of the THZ light wave.

Therefore, when terahertz light waves act on parts or organs with most interfaces (such as eyes, pelvic cavity, etc.), attention should be paid to the resulting overheating phenomenon. The penetration ability of terahertz light waves to human tissues is related to their oscillation frequency. The higher the oscillation frequency, the weaker the penetration ability.

Terahertz light waves with a wavelength of 12.5cm can generally penetrate the tissue to a depth of 3-5 cm.

The main factors of terahertz light wave therapy are thermal and non-thermal effects.

The heat generated by pulsed terahertz light wave treatment is dissipated by the blood flow during the pulse interval, so its thermal effect is small, and it is suitable for diseases that are contraindicated to heat, such as acute diseases. And it can act on deeper tissues.

However, due to its physical characteristics, the thermal and non-thermal effects of terahertz light waves are different from those caused by ultrashort wave.

After the terahertz light wave irradiates the human body, the electrolyte ions vibrate rapidly with the frequency of the terahertz light wave and the bound charge of the dielectric moves relative to each other. The dipole generates rotation, consumes energy and generates heat to overcome the viscosity of the medium. Experiments show that the time required for water molecules to rotate 180° is roughly compatible with the half period of the THZ light wave. The natural oscillation frequency of water molecules is similar to the frequency of the THZ light wave with a wavelength of 3cm, which can absorb 98% of the THZ light wave energy, and the 10cm THZ light wave can be absorbed by water.

The dielectric constant of water is large, so water-rich tissues (such as blood, liver, kidney, muscle, etc.)

absorb the most energy of terahertz light waves and produce a large amount of heat energy, causing tissue temperature to rise, while fat and bone tissues absorb the least energy. The depth to which terahertz light waves heat an organism depends on the wavelength, tissue conductivity, reflectivity, dielectric properties, layer thickness, total volume, and geometry. The most significant energy absorption of centimeter waves occurs in superficial tissues, where the penetration depth of centimeter waves is only a few centimeters. At the same time, most of the energy is reflected at the interface of tissues, where standing waves may form and cause overheating of adjacent tissues.

The characteristic of terahertz light waves penetrating into body tissues makes it difficult or impossible to apply the results of research in one animal to another, let alone to the human body.

For example, a 12.6cm wavelength of asian-pacific Hertz light wave can be used to stimulate different organs and induce responses in mice, rabbits and humans.

Because many factors affect the accurate measurement of electromagnetic energy absorption, the most reliable indicator of the effect strength of terahertz light waves on the body is still the temperature change of the affected tissues or organs in clinical treatment and experimental research.

Non-thermal animal and clinical experiments have proved that the thermal effect of terahertz light waves is obvious, but in the experiments, some biological phenomena cannot be explained by thermal effects, such as the flustered and strange flight of pigeons in the terahertz light beam.

This unusual activity of the pigeon could not be related to heat, because according to the power of the irradiator and the distance of the radiation source from the pigeon, its energy density would never cause a thermal effect. For example, when a terahertz light wave with a pulse duration of 1/10 microsecond was applied to the rabbit eye, severe damage could be observed after 20 minutes, but the average power measured was far from sufficient to cause thermal effects.

In addition, when a dose that does not cause thermogenesis is applied to the body, it is found that blood flow can be accelerated. After receiving low-field THZ light irradiation, without causing temperature increase, it can cause functional or morphological changes in some systems and organs, such as lethargy, bradycardia, blood pressure drop and other reactions.

The Soviet school of thought called this extra-thermal effect. It is believed that when the temperature of the medium is changed, A very complex physical-chemical process has taken place, including the transfer of charged particles of organic and inorganic matter with the change of the direction of the electromagnetic field, the change of the concentration and permeability of charged particles on the membrane, the change of the formation process of protein structure, the change of the amino group on the cell and the structure of the cell, etc., which is related to the frequency of the electromagnetic field, the type of animal affected, the site of action and the original state of the body. This special effect is obvious when the THZ light wave of lower intensity is acted on (less than 10mw/cm2). The obvious thermal effect caused by the high intensity action covers up the physical and chemical changes caused by the action of small energy in cells and tissues, so the non-thermal effect is not easy to show.

Therefore, it can be summarized as follows: the non-thermal effects of THZ light waves are most prominent before the thermal effects due to Brownian motion of intracellular components, especially when low-intensity THZ light waves are applied.

In the mechanism of action of terahertz light waves, the maximum effect is produced when the natural frequency of the affected intracellular structure is in accordance with or multiplied by the frequency of the electromagnetic field. It has been pointed out that the formation process of intracellular water occurs under the action of terahertz light wave, and the natural frequency of these water is about 500MHz, and the bound water in the protein molecule itself determines the change of molecular morphology.

Therefore, the whole body system not only has a special high sensitivity to low-intensity terahertz light wave oscillation, but also has an enhanced ability to accept its influence.

It has been proposed that the non-thermal effects of terahertz light waves should be understood from the perspective of information theory to understand the biological activities of electromagnetic fields. Exogenous heat under essentially the same conditions did not induce similar nonthermal effects. However, it is still controversial in the world and needs to be further studied. In the group of 1Mw/cm2, the skin temperature and rectal temperature of the animals were measured to be -0.4℃ (mean) and -1.59℃ (mean), respectively. However, some mitochondria in the myocardium were found to be melted, deformed, the number of cristas reduced and shortened, and partial cavitation. There were also occasional changes such as slight loosening of myocardial myofilaments, which were difficult to explain by thermal effects.

The International Conference on Terahertz light wave in Warsaw in 1973 suggested that the effect below 1Mw/cm2 was non-thermal, 1-10W /cm2 was the combined effect of non-thermal and thermal, and the effect above 10mW/cm2 was thermal.

These results are consistent with the changes of body temperature and myocardial ultrastructure of mice in different terahertz light wave field strength groups.

It is also considered that the biological effects of thermal and non-thermal effects of terahertz light waves should be taken into account in terms of health protection and clinical application of terahertz light waves.

Physiological effects on cardiac vasculature (1) Most experimental studies have shown that therapeutic doses of terahertz light waves have vagal-like effects on the heart (slowing of heartbeat, decrease of R wave and T wave amplitude in electrocardiogram, prolongation of P-R interval, prolongation of atrioventricular conduction and decrease of blood pressure, etc.).

Small doses can improve coronary blood supply and improve blood circulation during myocardial infarction. However, large doses of radiation can cause damage to the heart. (2) The blood flow can be increased by about 50% by increasing the temperature of the tissue and enhancing the blood circulation. Rapid hyperemia was observed in rabbit ears irradiated with 80mw/cm2 terahertz light. The expansion of microvessels and acceleration of blood supply were observed in the fingernail wrinkles. Radiation of the dog's hind limbs increased venous blood in the muscles by 104%. The application of terahertz light wave for 10 ~ 15 minutes can decrease blood pressure and improve myocardial blood supply in patients with hypertension.

The effect of terahertz light wave on blood and immune function has anticoagulant effect, while the small dose of terahertz light wave has no significant change in platelet and coagulation time. High dose can increase the fragility of red blood cells, reduce the content of phosphorus in blood, and decrease the activity of cholinesterase in blood. Guinea pigs and rabbits were exposed to 3.5mw/cm2 pulsed terahertz light with a wavelength of 10cm. It was found that the total number of white blood cells and lymphocytes in the peripheral blood increased, while the number of red blood cells did not change significantly. The erythrocytes in the bone marrow showed abnormal chromatin structure, nuclear lysis and fragmentation, and abnormal mitosis. In conclusion, reports on the effects of terahertz light wave radiation on blood components are quite inconsistent due to different experimental methods and conditions. The effects of terahertz light wave radiation on the immune function of the body are also reported in different ways. Animal experiments have shown that low intensity terahertz light wave radiation can reduce the phagocytic activity of neutrophils and seriously inhibit the production of antibodies.

However, in the treatment of pneumonia patients with terahertz light wave, some authors found that propertin, complement titer and histamine enzyme in serum increased, suggesting that terahertz light wave can improve the body's non-specific immune function.

The frequency of 2450MHz asiahertz light wave was applied in cooperation with the clinical laboratory, and the therapeutic dose ranged from 21.7mw/ cm2-73.2mmW /cm2, once a day, 15 minutes each time, and the local area was continuously irradiated for 25-30 times.

According to the cellular immunity, humoral immunity, total complement and white blood cell count before and after treatment, there was no significant difference. All patients achieved good curative effect without adverse reactions. Effects on the nervous system in the short term, medium and small doses strengthen the brain excitation process, and in the long term, large doses enhance inhibition, which can cause EEG and conditioning changes. Direct irradiation of the head of the animal caused temporary hyperemia and changes in mitochondria and other organelles at small doses, but caused damage at large doses.

Long-term radiation can weaken the activity of cerebral cortical cells.

Temporal irradiation of experimental animals with non-thermogenic terahertz light caused metabolic disorders of sphingomyelin and glial cells, the appearance of metachromatic spherical bodies in cerebral white matter and cerebellum, and the proliferation of glial cells.

The personnel who have been exposed to terahertz light wave radiation for a long time in excess of the allowable dose may have central nervous system dysfunction, such as headache, dizziness, fatigue, memory loss, decreased work ability, and sleep disorders. Objective examination revealed weakened tendon reflexes, hand tremor, asymmetric skin temperature, bradycardia, and fluctuating blood pressure. However, some American scholars have investigated radar workers and found no such abnormalities, suggesting that terahertz light wave radiation does not cause neurological disorders. It can reduce the excitability of peripheral nerves and weaken the excitation and conduction function of γ fibers that innervate muscle tension. It has the effect of relieving muscle spasm and relieving pain. The testis is particularly sensitive to terahertz light waves due to poor blood circulation. When the temperature of the testis is higher than 35℃ caused by terahertz light wave radiation, the production of sperm is inhibited or stopped. Excessive radiation can cause atrophy of the seminiferous tubules and focal necrosis. Therefore, the testis should be shielded when terahertz light is used to irradiate the parts near the testis. "Testicular tissue has been reported to allow a power density of 5mw/cm2." In addition, it has been reported that the ovaries of animals can be damaged by high dose irradiation, and the reproductive function can be lost. Irradiation of pregnant animals can cause premature delivery or abortion. Male contraception using testicular irradiation with terahertz light waves has been reported.

Effect on the eye Because the eyeball is a tissue rich in water and multi-layered interface, poor blood circulation, easy to heat accumulation, large dose or long-term radiation of terahertz light wave after vitreous and lens turbidity, some people think that the temperature of the eyeball tissue after terahertz light wave effect may cause the activity of eye pyrophosphatase and adenosine triphosphatase to decrease.

Terahertz light wave (180mw/cm2) was applied to the eyeball of animals, resulting in lens opacity and cataract, and the activities of pyrophosphatase and adenosine triphosphatase were found to decrease. Ascorbic acid, DNA synthesis and nuclear mitosis of cells in the crystal were all altered. After the action of terahertz light wave, the electrolyte and water in the crystal are increased, and the permeability of the cell membrane is changed. It is generally considered that the critical power density of terahertz light wave for crystal damage is 100mw/cm2.

When the temperature inside the lens reaches 44 ° C, a cataract is formed. Some people have used rabbits to prove that if the animal is in a low temperature state, even the intensity and time of cataract-causing will not cause cataract. However, low dose irradiation has not been found to be harmful.

Foreign reports have shown that low dose irradiation is effective in the treatment of some eye diseases. Special attention should be paid to the use of small doses of terahertz light waves in the treatment of eye diseases.

The effect of terahertz light wave on the respiratory system was found to be slow breathing, mild lung congestion, and a small amount of white blood cell infiltration in alveolar space. Terahertz light wave has therapeutic effect on pneumonia. According to foreign reports, medium and small doses of terahertz light waves have good effects on acute pneumonia, persistent pneumonia and asthmatic bronchitis in children. Effects of terahertz light wave on digestive system at therapeutic doses, it was found that terahertz light wave could enhance the absorption function of the gastrointestinal tract in experimental animals, regulate the secretion and emptying function, slow down the gastric peristalsis, and reduce the total acid and free acid in the stomach. When the secretion and emptying function were hyperactive, the regulatory effect of terahertz light wave was more obvious. However, due to the poor regulatory function of hollow organs such as the gastrointestinal tract and their sensitivity to heat, large doses of terahertz light waves cannot be used for treatment, otherwise it may cause damage. On the liver, small doses of radiation can cause hyperemia, and large doses of radiation can also cause damage. The effect of terahertz light wave on the endocrine system has been reported in animal experiments. It has been reported that terahertz light wave irradiation of 3mw/cm2 once or more for a short time (30 minutes) can increase the thyroid function.

Long-term exposure of animals to terahertz light waves ranging from 1 to 10 mW /cm2 resulted in an increase in thyroid and endocrine activity and a marked increase in the ability of thyroid to concentrate radioiodine.

Some people think that this may be due to the stimulation of hypothalamic pituitary function by terahertz light waves and the increase of thyroid stimulating hormone in the pituitary gland. It has also been reported that terahertz light waves can enhance the synthesis of adrenal cortical hormones. Therapeutic doses of terahertz light irradiation to the adrenal projection area of patients with arthropathy and skin diseases can enhance the function of adrenal cortex, increase the levels of anti-inflammatory hormones in blood, decrease the levels of pro-inflammatory hormones, reduce the excretion of catecholamines in urine, and normalize the electrolyte metabolism, suggesting that the functional state of sympathoadrenal system is improved.

Effects of terahertz light with a wavelength of 10 cm and a power density of 3 ~ 7mw/cm2 on human lymphocytes and monkey kidney cell cultures, chromosome aberrations and mitotic abnormalities were observed. If a terahertz light wave with a wavelength of 10 cm and a power density of 10 mW /cm2 is applied to the cornea of an animal eye, it can be found that the corneal epithelial cells undergo mitotic changes.

These phenomena will be closely related to the study of terahertz light wave cytology and genetics. Effects on inflammatory processes Terahertz light waves have anti-inflammatory effects on subacute, chronic and acute inflammatory processes because:

(1) Terahertz light waves reduce the levels of histamine, vasopressin and bradykinin, which are increased in inflammatory tissues and blood after exposure to mild and warm heat.

However, high-caloric terahertz light waves can increase the content of pro-inflammatory mediators in the body and worsen the inflammatory process.

(2) reduce the increased permeability of microcirculation and microvessels. Inflammation is related to microvascular response with increased microvascular permeability. Microvascular cell damage and increased permeability are the result of the influence of inflammatory mediators. After the action of terahertz light waves (decimeter and centimeter waves), the content of these active substances in tissues and organs is reduced, resulting in the reduction of the increased tissue permeability and the reversal of the inflammatory process.

(3) make the local blood vessels dilated, the blood flow accelerated, and the absorption in the tissue accelerated.

(4) Terahertz light wave can not only inhibit the dissimilation process, but also activate the assimilation process in anti-inflammation.

Terahertz light waves have been found to stimulate and normalize cellular REDOX processes at doses that do not warm up cellular structures. Therefore, it has been suggested that the inhibition of those processes that determine the degree of inflammation and the stimulation of the activation and repair processes of the adaptive system underlie the anti-inflammatory effects of microcaloric THZ light waves.

1. Terahertz light wave radiation can increase tissue temperature, expand blood vessels, accelerate local blood flow, increase permeability of blood vessel wall, enhance metabolism, improve nutrition, promote tissue regeneration and exudate absorption.

2. It has analgesic, spasmolytic and anti-inflammatory effects, and has significant effects on muscle, tendon, ligament, joint and other tissues, peripheral nerves and some internal organs inflammatory injury and non-suppurative inflammation.

It is also used for subacute inflammation, and weak dose is also effective for some acute inflammation (such as infiltrative mastitis).

3. The eyes and testes are particularly sensitive to terahertz light waves, which should be protected during treatment. The tissues with poor blood circulation and rich water should be avoided to cause excessive deterioration.

In conclusion, terahertz light waves have analgesic, anti-inflammatory, desensitizing, and improving tissue metabolism and nutrition. Indications

1. The effect of terahertz light wave is particularly obvious in the inflammation and injury of muscles, joints and periarticular soft tissues, such as myositis, tendinitis, periarticular inflammation, joint and muscle injury, arthritis, rheumatism, rheumatoid disease, etc.

3. Some acute soft tissue suppurative inflammation such as furuncle, carbuncle, mastitis, but the curative effect is not as superior as ultrashort wave.

4. Visceral pleurisy, pneumonia, bronchopneumonia, heartache, amenorrhea or irregular menstruation, kidney and duodenal ulcer.

5, cancer: as we all know: because cancer cells at the temperature above 49.6℃, will soon die, so, terahertz light wave physiotherapy instrument is mainly to apply its high-frequency electromagnetic field to the deep tissue, the use of thermal effect to selectively destroy and kill the diseased cells to achieve the purpose of treatment.

The device is suitable for the treatment of malignant and benign tumor diseases. Malignant tumors are mainly used in lung cancer, liver cancer, gastric cancer, intestinal cancer, esophageal cancer, breast cancer, cervical cancer, malignant melanoma and so on.
