This equipment is the use of medical common microwave frequency of 2540 MHz. microwave thermotherapy is to put the organism in the microwave radiation field to complete, So that it reaches a temperature a number of degrees higher than the body temperature, generally 45 ℃ ~ 49 ℃. At the same time different parts and keep a certain time to use time. Bio-thermal effect is: when the human body tissues are irradiated by microwaves, the body's polarized molecules, such as water molecules, under the action of microwave high-speed flip, friction so that the temperature of the tissues gradually rise, so it will make the human body tissues to produce a bio-thermal effect, and to obtain the medical effect, and destruction of hyperplasia tissues. Heat vasodilatation caused by increased blood flow, increase capillary pressure, increase the permeability of cell membranes and accelerate metabolism, so that muscle relaxation, eliminate spasm and relieve muscle spasms, to achieve the purpose of soothing and anti-inflammatory and other purposes, warming requirements are not stringent, characterized by the need to undress.
