Device for treating brain diseases based on pulse semiconductor laser external irradiation technology

Abstract

The invention relates to a device for treating brain diseases, in particular to a device for treating brain diseases based on a pulse semiconductor laser external irradiation technology, and solves the problems that irradiation light of an existing device cannot effectively penetrate through skull, irradiation treatment is carried out on deep brain cells of the skull, irradiation treatment can becarried out on the deep brain cells of the skull, and adverse effects cannot be generated due to over-high temperature. The device comprises a helmet, at least one pulse type laser generator, a powersupply and a main control box. The device is characterized in that: the helmet comprises a helmet outer layer, a helmet middle layer and a helmet inner layer; the helmet inner layer is made of a transparent material; and the light-emitting end of the pulse type laser generator is fixed on the inner side of the helmet middle layer. after laser penetrates through the helmet inner layer, the following conditions at met: the peak power density is 1-500 W / cm<2>, the average power density is smaller than 500 mW / cm<2>, the laser spot diameter is not smaller than 3 mm, the laser pulse width ranges from 1 ps to 10 ms, and the wavelength is 600-1400 nm.

Description

technical field [0001] The invention relates to a device for treating brain diseases, in particular to a device for treating brain diseases based on pulsed semiconductor laser external irradiation technology. Background technique [0002] Low-level laser therapy (Low-level laser therapy, or Low-level lighttherapy, LLLT) has been used for decades to treat tissue pain within 30 cm below the human skin. So far, researchers around the world have completed more than 500 various clinical trials and more than 4,000 animal studies in the laboratory, confirming that red light and infrared light with a wavelength of 600-1400nm can relieve pain and reduce pain. It plays an effective role in inflammation, regulating immune response, promoting wound healing, stimulating human acupuncture points, and promoting hair growth. Its biophysical principle is: the use of low and medium power densities (mW / cm 2 ) and high energy density (J / cm 2 ) quasi-monochromatic light, which produces photob...
