Abstract

The laser acupuncture stimulation has been applied extensively, but the laser is diffusely reflected by the skin as well as scattered and absorbed by the subcutaneous tissue, so the curative effect of the laser irradiation on the acupoints is limited. To solve above problem, we have developed the new laser deep acupuncture stimulator of diode. Its lasing wavelength is 630nm. The lasing beam is modulated into the special wave forms (such as sine wave, rectangular wave, etc.). The modulation frequency and phase may be self-synchronized in the patient's pulse. For the multi-acupoint are stimulated simultaneously, there are 3-7 laser pins on this stimulator. The modulated laser beams are coupled into 50/125 micrometers nonofil optical fibers separately. After that they enter into the laser acupuncture pins through the fiber optic connectors. The lasing beams and pins are stimulated as the customary acupuncture in the depth of the acupoints simultaneously. The output power of the single pin is 0.5-1.5 mW. The outside diameter of the pin is 0.4mm. For the price of the acupuncture pin is lower, thus the laser acupuncture pin can be used only once. Seven hundred patients were treated on the period of the clinical practice. The case of illness contains palsy, post-palsy, apoplexy, tenositis and sactalgia etc. The rate of efficiency (cure of improvement) is 85%.
