Cardiovascular Disease Therapy Device  Physical Laser Therapy Medical Device   What's the 650nm low level cold laser therapy necklace treatment and prevention angina heart care device Treatment range? It could treatment Angina, myocardial ischemia, coronary heart disease, cerebral insufficiency   Cardiovascular disease is the number one cause of death worldwide.  It is broadly defined to include anything which adversely affects the heart or blood vessels.  One-third of Americans have one or more forms of it.  By one estimate, average human life expectancy would increase by seven years if it were eliminated. Advantage: Laser therapy regenerates tissue, stimulates biological function, reduces inflammation and alleviates pain.  Implementing laser therapy in the treatment of cardiovascular disease offers the possibility of increasing the health and wellbeing of patients while reducing the costs and enhancing safety of medical care.        What's the 650nm low level cold laser therapy necklace treatment and prevention angina heart care device technical parameter ?    ITEM       ITEM DESCRIPTION Laser medium GaA/As semiconductor  Laser wavelength     650nm Laser output power 5mw for each laser probe Lase diode number  8pcs laser beam  Laser operating voltage 3.7-4.2V Input voltage of power 100V-240V Power source  Build in lithium battery(1000mAh) Default treatment time 10mins Environment temperature -20°C-40°C Relative humidity  80% Atmospheric pressure  86kpa-106kpa Packing  1pc/box,16.5X16.5X8.5cm, 0.55kg/pc   Working principle 1, Purify The blood:  It adopts low level laser with the wavelength of 650nm for household use, through specific parts of irradiation and using light radiation of laser and wavelength relation to change the biological characteristics and peel off the fat layer and cholesterol wrapped in the red blood cells, to improve the activity of the enzyme and oxygen carrying capacity as well as the deformability of cells, reduce the concentration of middle molecules in the blood, improve the rheological properties and lower triglycerides and cholesterol . 2, Smooth the blood flow: lauches 650nm laser wave to help eliminate the thick,sticky,viscous conditions of the blood,soften blood vessels,improve microcirculation,soften cardiovascular and cerebrovascular,prevent cardio-cerebral-vascular from contraction. 3, Protect the brain and nourish the heart. Function  “The treatment has been shown to have anti-anginal, antihypertensive effects, to improve cardiac performance and myocardial contractility, and to increase myocardial, coronary and aerobic reserves. This clinicofunctional efficacy was accompanied by positive shifts in lipid metabolism, lipid peroxidation activity, antioxidant defense, hemocoagulation and microcirculation.”     “Laser treatment significantly lowered systolic, diastolic and mean arterial pressure. Moreover, diastolic arterial pressure did not elevate high at submaximal bicycle exercise. Total peripheral vascular resistance also decreased. A good hypotensive effect was achieved in 90.4 percent of cases.”
