When the low level He-Ne laser irradiation on both extracorporeally and intracorporeally circulatory blood, it has following useful stimulating functions for the living things: reduce the content of blood plasma middle-molecule substances, increase serum superoxide dismutase, improve hemorheological properties, raise immunity function of organism, etc. We developed the intravascular low level He- Ne irradiation therapeutic apparatus. A He-Ne laser beam of 632.8nm is coupled into 50/125 micrometers optical fiber with the aid of the free lens coupler, after that it entered into the laser pun through the fiber optic connector. The attenuate coefficient of the lens coupler can adjust continuously, so as to choose continuously the output power of the laser pin from 0 to 5 mW. In the pipe of the laser pin there is a large core fiber of 150/190 micrometers, they are stuck to each other. The diameter of the laser pin is less than 0.4 mm, thus it may get into infusion pin of 7, not used with intravenous casing pipe pin. Because it is adopted that the low priced fiber-optic connector, the laser pin can be used only once.
