低能量激光理疗仪的电路设计

he low energy laser acts with the biology can have the biological effect, if we apply this biological effect in the medicine, it may cure certain disease. There is weak laser biology effect stimulated by the laser, if the organism is illuminated by the laser physical therapy meter with the low power laser; that enable patients to restore their health with the help of this equipment. The wave of near-infrared and the laser of visible light have many physiological actions and treatment functions to organism and these can be shown by the improvement of partial blood circulation, nervous system function and anti-infection and the promotion of polygenesis of organism, as well as the analgesia function. The research about the use of the low energy laser in the medicine treatment is on the rise; along with the rapid development of semiconductor technology, kinds of light emitter diodes (light emitting diode, LED) with different length of wave have been developed and applied widely in various professions. At present, the application of LED in biomedicine is increasing day by day; at the same time it has assumed good prospects for development in the application of biomedicine. This article simply introduces the related content of the application of the low energy laser in the medicine treatment and mainly introduces the circuit model about low-energy laser therapy instrument, designed by ourselves.
