Zhou Lin spectrometer adopts bionics principle and electronic technology, which can approximately simulate the radiation spectrum of human body. When working, electromagnetic energy is transformed into biological energy easily absorbed by human body through irradiation. Based on the principle of matching absorption, the focus produces "biological thermal effect" and "non-thermal effect", which promotes the physiological and biochemical reactions of the body and produces four important biological effects: 1, promotes blood circulation, eliminates microcirculation disturbance 2, and regulates and improves the immune function of the body. Soft tissue injury; Osteoarthropathy; Lumbar muscle strain; Cervical spondylosis has a good curative effect. Generally, large medical equipment stores in Hangzhou sell them, and there is one in the north of Shangtang Road Plastic Surgery Hospital. I didn't know it was nine years old until I consulted.
