The functions of the microwave therapy device are divided into physical therapy function and treatment function. The treatment function is actually the thermal coagulation surgery function of the microwave therapy device.
1.0 Physiotherapy function:
The physiotherapy function is the most basic and core function of the microwave therapy instrument, which is to send the microwave energy generated by the host to the inflammatory tissue lesions of the human body through the microwave physiotherapy head. At present, the common frequencies of microwave therapy devices are 2450GHz and 915MHz. The frequency of most microwave therapy devices on the market is 2450MHz. Through conversion, we can know that the wavelength of electromagnetic waves corresponding to this frequency is 12.24 cm. The infrared and spectrum, TDP and magic lamp. They are all electromagnetic waves with a wavelength less than 1000 microns, that is, electromagnetic waves with a wavelength less than 1 millimeter. Since the wavelength of microwaves is much longer than the wavelength of infrared rays, spectrum, etc. Therefore, as a microwave, which is also an electromagnetic wave, the penetration of its electromagnetic wave during physical therapy is much stronger than other common thermotherapy instruments, and the irradiation depth can reach 5-6 cm depth. The clinical effect of microwave is divided into two parts: thermal effect and non-thermal effect.
1.1 Thermal effect
The thermal effect is an effect related to the increase in temperature of human tissue caused by microwaves. Microwave is a type of electromagnetic wave. From a physical perspective, it is an electromagnetic wave with a frequency of 2450MHz, a speed of 3*108 meters/second, and a wavelength of 12.12cm. It is an energy with alternating electric fields and alternating magnetic fields. When microwaves (through microwave physiotherapy head) is irradiated to human tissue, the energy can easily reach a depth of 5-6 centimeters in the human body, and prompt the polar molecules, mainly water molecules, in this range to rotate and oscillate at high speed, because the molecules generate a large amount of energy due to mutual friction. The heat of the tissue will rise significantly and rapidly, so the basis of the microwave thermal effect is not only that microwaves are electromagnetic waves, but also that microwaves have long wavelengths, which can increase the temperature of deeper tissues in the human body, this is the most needed process to improve blood circulation and reduce inflammation.
Judging from our current physical methods, microwaves have penetrating power that other non-radio frequency physical factors cannot have. Therefore, microwave therapeutic devices promote blood circulation, promote the absorption of inflammatory metabolites, and promote cell metabolism. The most prominent one is also the method most needed clinically, and this method is impossible to have with other methods. Therefore, it is very accurate and scientific for the international academic community to regard microwave therapy devices as equal to inflammation therapy devices.
1.2 Non-thermal effects
We just mentioned that microwave is a type of electromagnetic wave, which is energy with alternating electric fields and alternating magnetic fields. This is a clinical effect that starts to work when the microwave energy is very low and is not enough to cause temperature changes in human tissue. Let’s analyze, when the alternating electric field, that is, the energy of the high-speed alternating positive and negative electrodes, acts on some charged substances in the human body, it will definitely cause them to alternately oscillate, which can cause a series of biological changes and change the aggregation state of red blood cells, which causes the aggregation and depolymerization of red blood cells in the blood that affects blood viscosity, greatly reduces blood viscosity, and accelerates blood flow; the cell membrane has a certain degree of ion adsorption and a certain membrane potential, so when the alternating electric field acts on human tissue, it will affecting the material metabolism and exchange of cell membranes, it greatly improves cell metabolism; alternating electric fields and magnetic fields will increase the activity and efficacy of enzymes in the human body, and the activity of enzymes that are active participants in cell metabolism will also further improve its strengthens the self-healing and repair capabilities of human cells, which is one of the most needed functions of the human body; human milk fat has a certain dielectric coefficient, so the milk fat will form a string arrangement under an alternating field, which will affect the biochemical processes of the tissue. Act as a catalyst. A series of non-thermal effects of microwaves have attracted more and more clinical attention in the past 20 years, and their miraculous clinical effects have brought a high degree of surprise to the medical community.
2.0 Therapeutic functions
Many people don’t know much about the therapeutic function. In fact, the therapeutic function referred to clinically is the surgical thermal coagulation function of microwave instead of laser. When we output microwaves with a power of tens of watts through a small area, due to the energy density of this energy is very high, reaching the point where the temperature of the parts of the human body exposed to microwaves can quickly rise to the temperature of thermal coagulation of proteins, leading to protein coagulation and necrosis. Microwaves have been used clinically for the coagulation of hyperplasia, ulceration and some excrescences, and due to the heat energy during coagulation is highly controllable, so microwave treatment, that is, thermal coagulation surgery, has the advantages of no smoke, no sputtering, and no tissue carbonization, and the depth is controllable. Wound healing after surgery is much easier than after laser surgery, its miraculous clinical effectiveness has brought great surprise to the medical community.
