In recent years, as a new treatment method, red light therapy devices uses in the clinic widely. All kinds of red light therapy devices have been put into the market, hospitals, homes, and have gained many successful experiences in the fields of dermatology, surgery, internal medicine, gynecology, and other applications.
Red light therapy, using visible light 600-700nm (more than 90%), infrared light 700-900nm (less than 10%) integrated light waves for external irradiation so that it produces important biological effects and therapeutic effects. Mitochondria in cells absorb the more red light.
Usually, we see the medical-grade red light therapy device is composed of two wavelengths, light source wavelength is divided into 660nm and 850nm to adapt to different patients.
After red light is irradiated, the catalase activity of mitochondria increases, which can increase cell metabolism, glycogen content, protein synthesis and the decomposition of adenosine triphosphate, thereby strengthening the cell Regenerate, promote the healing of wounds and ulcers.
at the same time, it also increases the phagocytosis of white blood cells and improves the body's immune function. Therefore, many diseases can be treated clinically. So some clinics use red light therapy devices to treat patients.
1, light color pure, no impurity light, small side effects
2, for Visible Light Band, deep penetration of the human body, good efficacy
3, large light spot, for the treatment of large areas of disease to provide better treatment
4. No harm, no toxic side effects of the green treatment program.
The Red Light therapy device is different from the physical therapy device. The mechanism of the red light therapy device is mainly the photochemical action to the organism, which produces the important biological effect and the therapeutic effect.
The red visible light band of 600 ~ 700nm is obtained by the special filter, which has the advantages of deep penetration, good curative effect, Large Light Spot (several hundred times of He-Ne laser), uniform irradiation, and no burn-in clinical application. It provides a better method for treating local or some large area disease.
After exposure to red light, the activities of various enzymes, such as Catalase and Superoxide dismutase, are stimulated, which can increase the cell metabolism and the content of Glycogen, increased protein synthesis and ADENOSINE triphosphate breakdown promote cell regeneration, healing of wounds and ulcers, and regeneration of damaged nerves.
At the same time, it also increases the phagocytosis of white blood cells, which reduces the content of Serotonin and acts as Analgesia, thus achieving the effects of anti-inflammation, detumescence, analgesia, and antipruritic. The penetration depth of red light in human tissues is above 2.5 mm (about 3mm), which can directly affect lymphatic vessels, blood vessels, subcutaneous tissues, and nerve endings. Red light is absorbed by cells and resonates with human tissues.
A series of biological reactions, such as thermal effect and photochemical effect, can be produced through the cascade reaction. Red Light can promote cell proliferation and growth, not only can enhance cell activity but also for immunocompromised patients have some improvement.
The Red Light therapy device has also obtained an obvious effect in the treatment aspect of many diseases, the inquiry material may see many about the red light therapy device to use in the concrete case curative effect report.
For example: In 2015, the Department of orthopedics at Bethune International Peace Hospital in Shijiazhuang explored the application of red light therapy in orthopedics, and 187 patients who were treated with red light from January to December of the same year were selected to observe the therapeutic effect. The red light therapy uses for patient's results are as follows:
After local treatment with red light therapy device, most of the patients got a good curative effect. In a short period of time, it can promote protein solidification, improve local blood circulation, improve the metabolic capacity of local tissue, and produce a series of benign reactions.
Red Light therapy device is a kind of physiotherapy device that can be used in the clinic. It has a simple operation, a Wide Application Range, and a good curative effect on various wounds.
1. The range of indications is wide. To many Common Diseases All have the curative effect, can accelerate the wound healing, thus reduces the swelling, the antiphlogistic, the Analgesia;
2 Non-contact treatment. Generally do not use with human contact, to a large extent can avoid cross-infection;
3. Treatment of superficial Lumen. General with the treatment instrument with an optical catheter, ear, nose and throat, rectum, cervix, and other shallow cavity disease treatment, safe and convenient;
4. Adapt to a wide range of people. The elderly and children are easy to accept, no pain, patients with a light burden.
The unique mechanism of red light therapy determines the clinical value of it. of course, The red light therapy device also has shortcomings. Mainly when using the red light therapeutic devices, not directly to the eyes, but also to pay attention to avoid newborn and pregnant women's abdomen, can not irradiation with artificial pacemaker patients.
