Thus, subcutaneous vein image will be displayed on the skin surface of the corresponding position External structure: Working principle: Use of a particular wavelength near infrared radiation skin, blood vessels because of the existence of hemoglobin to absorb the light, and other organizations are weak to strong light scattering and absorption, using near-infrared photography devices capture reflection or scattering of near-infrared light, will be the information captured through photoelectric conversion and image processing, finally locating veins location projection to the corresponding parts, for medical personnel real-time observation of blood vessels. Hardware features: 1. The use of invisible near-infrared light source, no harm to human body, no visible light pollution to the environment. 2. Simple operation, one-button power on/off. 3.360-degree rotating wheels to ensure accessibility. 4. With its own battery design, it can
