Microwave therapeutic instrument directly acts on human body through electromagnetic wave with wavelength of 1m- 1mm and frequency of 300 MHz-GHZ, which produces thermal effect and non-thermal effect, that is, "biological effect", improves local blood circulation, accelerates metabolic process, strengthens local tissue nutrition, enhances phagocytosis of white blood cells, promotes harmful substances to be excreted, and enhances tissue regeneration ability, thus achieving spasmolysis and analgesia.
The red light therapeutic instrument is a kind of phototherapy equipment which mainly obtains red visible light waves of 600~700nm through special filters. The mechanism of treatment is to produce photochemical effect on the body and achieve therapeutic effect. After human body is irradiated by red light, the activity of mitochondrial hydrogen peroxide, which has the strongest absorption of red light, can be increased. Promote cell metabolism, increase glycogen content, protein synthesis and adenosine triphosphate decomposition, promote cell synthesis, promote the healing of wounds and ulcers, and accelerate the regeneration of damaged nerves.
The electromagnetic wave emitted by the microwave therapeutic instrument is an invisible UHF electromagnetic wave; The red light therapeutic instrument emits red visible light waves.
Microwave therapeutic instrument can be used in surgery, but red therapeutic instrument can't be used in surgery.
In the field of physical therapy, the microwave therapeutic instrument can be used for treatment through clothes, and the red therapeutic instrument must expose the skin and directly irradiate the focus.
As for the curative effect, it still depends on the specific situation.
