Red light therapy instrument is a new type of light therapy equipment that can be applied in hospitals and homes. Its basic principle is to get the red visible light band mainly from 600 to 700nm through a special filter, which penetrates deeply into the human body and has better therapeutic effect. The output power of the whole machine is high (equivalent to more than a hundred times of He-Ne laser), and the light spot is large (equivalent to hundreds of times of He-Ne laser), which provides a better treatment method for some large-area diseases. Therapeutic mechanism Product performance Red light therapy instrument is manufactured with different selective absorption characteristics; it can induce protein solidification of lesioned tissues in a relatively short period of time, improve local blood circulation, enhance immune function, promote the metabolism of local tissues and produce a series of benign reactions, promote the generation of new squamous epithelial cells, accelerate the absorption of exudates, weaken muscle tone, thus achieving swelling, anti-inflammatory, The purpose is to reduce swelling, anti-inflammation, analgesia, eradicate erosion tissue, accelerate wound healing and even remove disease. The therapeutic mechanism of the red light therapy instrument is to produce photochemical effects on the organism, so that it produces important biological effects and therapeutic effects. The mitochondria in the cells absorb the most red light, and after red light irradiation, the peroxidase activity of mitochondria increases, which can increase the metabolism of cells; make the glycogen content increase, protein synthesis increase and adenosine triphosphate decomposition increase, thus strengthening the new cell and promoting the healing of wounds and ulcers; also increase the phagocytosis of white blood cells and improve the immune function of the body. Thus, it can treat a variety of diseases in clinical practice. From a long period of clinical trials and collected usage reports and papers, it can be seen that the red light therapy device can be used to treat many diseases in dermatology, surgery, internal medicine, gynecology, burns, ENT, etc. when used properly with supporting drugs.
