The principle of microwave treatment of disease is relatively complex, as evidenced by the results of current research at home and abroad, microwave treatment of disease is mainly through the thermal and biological effects to achieve. Due to the existence of magnetic resistance between the polar molecules on the oscillation of the damping effect, which consumes microwave energy and heat, the use of heat to achieve the purpose of treatment, which is the thermal effect of microwave therapy. Research and experiments have shown that the use of microwave irradiation of the lesion, its therapeutic effect far exceeds that of other heat application methods.
Microwave thermal effect
Most of the components of the human body are carbohydrates, carbohydrate molecules are polar molecules, polar molecules in the microwave field, with the microwave frequency change its polarity called polar oscillations, polar oscillations of the same frequency as the microwave frequency, its amplitude is proportional to the microwave intensity. As we know, Chinese medicine through hot compresses, acupuncture can treat cold and local inflammation; through the body’s own heat, can achieve autoimmune function, so make people think, microwave irradiation to the human body after the heat generated by whether it can achieve the purpose of curing disease? The main reasons for the effectiveness of microwave heat therapy are.
Main reasons
(1) microwave thermotherapy is the microwave irradiation to the lesion site, the lesion tissue absorption of microwave energy generated heat itself, so the lesion tissue than other hot compresses to warm up faster, and the temperature distribution is uniform.
(2) microwave heating characteristics of choice: the dielectric constant of various tissues in the human body is not the same, so the ability of various tissues to absorb microwaves is not the same. Absorption of microwaves is strong tissue heating, the absorption of weak heating is slow. Diseased tissue is often stronger than normal tissue absorption capacity of microwaves, heating up faster, thus achieving the purpose of the selected treatment. Other heat treatment methods, there is no this feature.
(3) microwave thermotherapy can diagnose the lesion site, while other heat treatment methods can not: if the lesion site is inflammatory, the lesion site microvascular compression by the inflamed tissue and narrowing, resulting in poor blood circulation, when the microwave irradiation lesion site, inevitably irradiated to the lesion site adjacent to the healthy tissue, that is, the lesion and healthy tissue at the same time by microwave heating. For healthy tissues, most of the heat generated by the absorption of microwaves is taken away by the circulating blood and distributed to the outside of the body through the skin: for lesioned tissues, the temperature rises sharply due to poor blood circulation. When the temperature of the local lesion tissue rises to 38℃-39℃, the affected part will have a painful feeling. The painful area is the lesion site, thus accurately identifying the location of the lesion, a feature that is beneficial for improving the efficacy and shortening the course of treatment.
Treatment mechanism of the disease species
The following is a specific analysis of the mechanism of treatment of some diseases that are particularly effective in the microwave thermal effect treatment.
(1) The mechanism of treatment of inflammation.
Inflammation is often due to injury, bacterial or viral infections, certain vitamin deficiencies and allergies caused by local lesions. The main feature of the lesion is poor blood circulation. When the microwave irradiation to the lesion, the lesion tissue will rapidly warm up, when the temperature of a certain part exceeds a certain threshold, the body will produce self-protection reaction – that is, to strengthen the blood supply to the site, improve the conditions of the circulation of the lesion, while increasing the nutrition of the lesion, so as to open the capillaries blocked by the compression, so that the blood circulation of the site tends to normalize, so that the gradual disappearance of inflammation.
Microwave itself has the characteristics of sterilization and disinfection, plus the thermal effect of sterilization, so as to achieve the purpose of the anti-inflammatory.
(2) The mechanism of tumor treatment
A large number of domestic and foreign studies have proved that tumor cells will shrink and die at a temperature of 42.5-43.5℃. Before the emergence of microwave therapy, domestic and foreign countries have been confused to find the method of heating tumors. This problem was solved only after the emergence of microwave heating.
There are two ways to treat tumors with microwave, one is to irradiate the tumor from outside the body, and the other is to send the microwave to the affected area and irradiate the tumor directly. However, there is a common requirement: the temperature of the lesion must be kept within the range of 42.5-43.5℃, low temperature is ineffective for tumor treatment, high temperature will cause damage to the healthy tissues around the lesion, therefore, when microwave treatment of tumors, the temperature of the tumor site must be strictly controlled. Therefore, when treating tumors, the temperature of the tumor area must be strictly controlled. At present, domestic microwave tumor treatment instruments have been produced that can accurately measure and control the temperature of the treated area.
Please rest assured that there is no damage to the healthy tissues irradiated by microwave for the reason that the blood flow in the tumor site is not smooth and the temperature rise under microwave irradiation is much faster than that of normal tissues. When the temperature of the lesion rises to the treatment temperature (42.5-43.5℃), the temperature of the normal tissue will not exceed 37.5℃. The reason is that the heat generated by the microwave in the normal tissue is taken away by the normal circulation of blood and distributed outside the body. According to Li Dingjiu’s “thermal therapy”, personal tissue temperature below 38.5 ℃, there will cause cellular tissue degeneration.
(3) The principle of microwave therapy for traumatic bleeding
For traumatic bleeding, microwave irradiation of the wound not only stops bleeding quickly, but also prevents wound infection and accelerates wound healing, the reasons are.
When the microwave irradiation to the flow of blood outside the wound, the blood absorbs microwave heat, the water in the blood quickly evaporates, the blood immediately thickens and coagulates, the coagulated blood clogged blood vessels and wounds to achieve the purpose of hemostasis. In the microwave thermal effect and make the polar molecules switch polarity at high speed, germs (such as Escherichia coli, staphylococcus, microbial, etc.) will be killed, thus playing a sterilization effect, so that the wound is not infected, especially for the prevention of tetanus is most effective. Microwave irradiation to the body not only has a thermal effect, but also cause biological effects, under microwave irradiation, can accelerate blood circulation, and thus can provide sufficient nutrients to the wound, thereby accelerating wound healing.
(4) the principle of microwave thermal therapy for internal bruising
A large number of experiments have shown that microwave heating treatment of postoperative internal bruising has a significant effect.
For the body if there is local bleeding, it will form a bruise clot, which feels like a hard lump when touched from outside the body. When the microwave shines on the place, the blood vessel is blocked, the blood flow is not smooth, when the microwave shines on it, the bruise absorbs the microwave energy to produce heat, forming local heating, because the water in the body is not easy to evaporate, the blood clot is thinned, at the same time, due to the body’s own protective reaction to the location of the lesion to provide a large number, so as to open the blood vessels blocked by the bruise, the blood supply becomes smooth, the bruise is absorbed by the tissue. The hospital concerned with microwave treatment of postoperative bruising more than 70 cases, have achieved amazing results.
(5) microwave thermotherapy can also be used to the treatment of intracorporeal diseases. However, the treatment requires the microwave radiator to the cavity lesion, the treatment principle with (3) and (4). In order to achieve good results and patient safety, there must be strict and accurate temperature measurement and control devices and technical measures to ensure the safety of intracavitary treatment.
(6) Microwave thermotherapy, which can also be used for purely physical treatment, such as curing the anterior glands. Open up the esophagus blocked by esophageal tumors, removal of intestines, uterine polyps, etc.. The principle of treatment is that the bipolar radiator is sent to the affected area for transient discharge to cure the diseased tissue. The essence of this treatment method is to burn the diseased tissues from the surface to the inside gradually through the skin-tending effect of microwave, so as to achieve the treatment purpose. When using this treatment method, the following matters should be noted.
a. The location of the lesion should be accurate.
b. Appropriate cooling measures should be taken for the treatment area in time.
c. Local anesthesia should be applied to the treatment area.
d . Antimicrobial drugs should be taken after treatment.
Non-thermal treatment
The so-called non-thermal treatment is to irradiate the weak intensity of electromagnetic waves to the relevant parts of the body, through the biological effects produced by it to achieve the purpose of treatment of disease treatment methods.
A large number of life reality and experimental evidence, microwaves will cause biological effects on the human body: for example, with 2450MHZ, power density of 5mw/cm microwave irradiation of human acupuncture points, the illuminated acupuncture points will have a sore Shen like acupuncture, with weak microwave irradiation of the Yongquan point, there will be a comfortable feeling of the whole body (coronary arteriosclerosis of people with dizzy feeling), but no heat sensation. With 35GHZ, 70mw millimeter wave power irradiation points will increase white blood cells …, it can be seen that the non-thermal effect exists, and the development of a successful “whitening instrument”.
Some foreign experts believe that microwave irradiation of the human body to produce microwave biological effects, because the human body has an inherent frequency of various tissues, when the microwave frequency is the same as the inherent frequency of an organization, the organization will produce resonant absorption. When the organization absorbs more energy than a certain reduction threshold, it will cause biological effects. The Soviet Union has more research results in this area.
