Principle of Treatment: Laser Rihinitis Therapeutic Apparatus is based on modern medicine and clinical practice research and development of semiconductor laser therapeutic instrument. The instrument adopts the semiconductor light produce wavelength of 660 nm, 8-12 mw low visible laser intensity, irradiation treatment to the nasal cavity, activate blood physiology. Function: 1. Improve the rheology of blood cells, improve red blood cells, biological activity, reduce platelet aggregation, so that the blood rheology. 2. Reduce blood viscosity, blood fat, cholesterol, dilate blood vessels, adjust blood pressure, improving microcirculation, obvious effect on preventing thrombosis. 3. Super low intensity light can also activate certain receptors, produce photochemical effect, make the blood gases and nutrients metabolism increases, it is good for blood to carry oxygen metabolism, improve body oxygen and nutrition supply. Features: 1. Adopts low-level laser irradiation which is painless, non-invasive, no side effects and has good rapid effects. 2. The instrument does not contain pharmaceutical and chemical components. Laser treatment fundamentally enhances the detoxifying capacity and immunocompetence. 3. It's a household portable instrument. 4. Laser head jackets to make the treatment cleaner and healthier. 5. Power: 9v battery (not included). How to Use: 1. Remove the battery cover. 2. Put 1 9V alkaline battery into the battery box. 3. Connect the wire and the device. 4. Take off the small pin cover before you use. Put the rubber nose clip into the nose, make sure 2 light points into the nose about 1 cm to 1.5 cm depth. 5. The green light keeps lighting shows working normal, if it is flashing, shows operation failure (low battery, or the wire didn't put in a correct way). 6. The green light will auto-turn off after one treatment session is over (15 minutes). 7. Use it 1 session a day. How to Clean: 1. Use a soft cloth to clean the light point, please don't immerse in water. 2. Disinfection: The light point can be disinfected by 70 percent alcohol. 3. Protect: Please don't use the same device for different persons.
