The main medical applications of low-intensity laser therapy include laser physiotherapy, laser acupuncture and laser blood irradiation. Among them, the application of laser physiotherapy and laser acupuncture is more common, but laser blood irradiation treatment is not known to most people. Low-intensity laser blood irradiation therapy is to irradiate the blood with a specific wavelength of laser light, and use the photochemical effect to promote a series of physiological and biochemical changes in the body, so as to achieve the purpose of treating diseases. Zheng’an Sangao Therapeutic Apparatus adopts the method of irradiating the radial artery with laser. The irradiated part of the blood vessel is superficial, convenient and safe to carry, and belongs to the arterial irradiation, which is an ideal irradiation method at present.
The use of low-intensity lasers for the treatment of “three highs” began in the 1980s. After nearly 30 years of practice, the medical community has a comprehensive understanding of its efficacy, including preventing thrombosis, lowering blood viscosity, lowering blood lipids, lowering blood sugar, lowering blood pressure, and lowering atherosclerosis, etc.
In order to accurately understand the efficacy of low-intensity lasers in the treatment of “three highs” and cardiovascular and cerebrovascular diseases, I have cooperated with relevant units to irradiate old experimental mice with low-intensity lasers, observe the changes in blood-related indicators before and after irradiation, and communicate with young experimental mice. The method of rat comparison was verified. The results showed that after low-intensity laser irradiation, the blood indicators of the old experimental mice were significantly improved, which were comparable to those of the young experimental mice. Whether it is animal experiments or clinical experiments in recent years, it is enough to prove that low-intensity laser blood irradiation has a good effect on “three highs” and cardiovascular and cerebrovascular diseases.
