Microwave is a very short wavelength radio waves, it includes the wavelength range usually refers to the frequency 300MHz ~ 300GHz (or wavelengths in the 1m-1mm) between the electromagnetic waves. Microwave multifunction therapeutic apparatus, is the use of poly-thermal effects of microwave exposure to the human lesions, where water molecules with the microwave field and the vibration of fever, to accelerate blood circulation and tissue metabolism, promote blood and nerve function recovery. In particular, inhibiting bacterial

growth, inflammation, swelling has remarkable curative effect. A wide range of its applications, efficacy significantly, many domestic and foreign medical institutions have been adopted for the treatment of some diseases have achieved satisfactory results.

WB-3100-type microwave apparatus using microwave frequency is 2450MHZ, its role in the human body on the depth of 3 ~ 5cm, on the local effects of a certain time, the temperature at 5cm depth can be increased to about 40 , its thermal effects penetrate strong, with high efficiency, which is infrared, short, and ultrashort-induced heat of unmatched, and its penetration through the fat layer to the muscle layer, so the use of microwave energy could be blood circulation, anti-inflammatory, analgesic, for a variety of inflammatory significant effect.
