HUAAN Laser Cardiac/Cerebral Disease Therapeutic Apparatus applied the radiation of the low level laser with 650 nm wavelength automatically controlled by electronically time-controlled program, with the laser penetrating human's skin, muscle, and vessel walls, so that the red blood cells take the energy from laser to restore its normal ability carrying electricity. As a result, the superficial fat layer of the red blood cells are forced to be dissolved, and then sugar metabolism is progressed, so that the blood oxygen saturation and microcirculation of the blood are improved, and then the blood metabolism achieves balance. Through irradiating on superficial skin of arteriae radialis, various metabolic enzymes are activated, fat mal-metabolism is corrected, and dextrose is driven to decompose, so that human immunity is improved, fat oxygenation are prevented, free radicals in blood are accelerated to be eliminated, and blood flow parameters are bettered. As a result, the blood fat, blood sugar, blood viscosity are effectively reduced, and the blood pressure is controlled effectively as well. Power output: 20mW, it is only 1/50 of the biological damage threshold(800mW)
