The active yang needle laser therapeutic instrument is good. The Yang-activating needle laser therapeutic instrument causes a series of response reactions in the body tissue, which makes it produce various physiological effects, changes its blood flow characteristics, and reduces the whole blood viscosity and platelet aggregation ability. Improve the production of ATPase, improve its deformability and fluidity, increase the oxygen carrying capacity of red blood cells, and increase the utilization rate of oxygen by the body. Improve the metabolic function of the body, improve microcirculation, reduce the molecules in the body, improve the activity of SOD, and have a good effect on toxins and free radicals in the blood. Laser therapeutic instrument is a kind of medical equipment that uses laser technology to treat.
