High-energy UV therapy instrument 【TheralightUV120-2】is an American product exclusively distributed by Beijing Kanglian Medical Equipment Co. With UVA and UVB dual-spectrum output, emitting UVA light peak 330nm and 365nm, for PUVA therapy; UVB light peak 302nm and 311nm “weighted wavelength 304nm”; radiation intensity is automatically calibrated and adjusted by the device, soft liquid optical fiber conduction makes the treatment reach a high degree of precision and targeting. High-energy ultraviolet light is radiated through the treatment handle of nearly 4 square centimeters, which is convenient to use, safe and economical, and highly intelligent, among which UVA high-energy ultraviolet light is the only UVA high-energy ultraviolet light treatment equipment in China at present. High-energy ultraviolet light not only has high energy and small adverse reactions, but also overcomes the shortcomings of NB-UVB treatment range and inaccuracy. High-energy UVB treatment instrument is especially suitable for the treatment of vitiligo and psoriasis, in addition, it can also be applied to the treatment of many allergic and inflammatory diseases. The clinical observation of our department shows that the high energy ultraviolet ray in the treatment of vitiligo and psoriasis has indeed achieved high efficiency, rapid, safe and reasonable. It is worthy of being a “high energy” product.
