311 narrow spectrum UVB dermatology treatment instrument

Principle of treatment

At present, most hospitals use PUVA technology, which requires simultaneous irradiation of UVA ultraviolet light and oral photosensitive medical tablets. However, the side effects caused by UVA and the side effects caused by photosensitive medical tablets are obvious. The narrow-spectrum UVB illuminator solves the problem of excessive UV exposure. Not only can the patient fully receive the light of the narrow-spectrum UVB emission in the range of 311-312 nm (this range is the most beneficial part of natural sunlight), while UVB treatment does not require taking other auxiliary medicines. The side effects of using photosensitive medicine in traditional PUVA methods are avoided, and these features make narrow-spectrum UVB increasingly popular among patients and doctors.

Traditional broad-spectrum UVB lamps emit light in the wavelength range of 280-330 nm, and clinical studies have shown that light below 300 nm can cause severe burns and increase the risk of skin cancer. Therefore, 311 narrow-spectrum UVB emission of light in the 311-312 nm wavelength range is considered to be the safest and most efficient light.

Treatment advantage

The emergence of 311 nm narrow-spectrum UVB has made it possible to improve the irradiation intensity and shorten the treatment time, which has greatly improved the therapeutic effect of various skin diseases. 311 narrow-spectrum uvb is also a new method for the treatment of vitiligo. After phototherapy, the skin lesions in the patient can increase the tyrosinase activity in the skin, which promotes the synthesis of melanocytes, thereby achieving the purpose of cure. Clinical practice shows that the 311nm narrow spectrum The efficacy of UVB is superior to traditional phototherapy. In clinical practice, we also found that before the application of 311 narrow-spectrum UVB treatment, such as combined with traditional Chinese medicine fumigation treatment system or medicated bath therapy will achieve better therapeutic effect.

Superiority

Short course of treatment, fast effect, total effective rate of more than 90%; no need to take other auxiliary drugs, avoiding the side effects caused by the use of photosensitizing drugs; effective light output intensity, no phototoxic side effects, good safety and tolerance Sexuality has no significant effect on normal skin, avoiding the possibility of skin burns and carcinogenesis caused by traditional broad-spectrum UVB.

treatment method

311 narrow-spectrum UVB dermatological treatment instrument is better than broad-spectrum UVB, the incidence of erythema reaction is low, the disease remission time is long, the effect is similar to PUVA, but no medication, low cost, can be used for pregnant women and children, small carcinogenicity Wait. Irradiate once every other day, 15-20 times for a course of treatment. Clinical results in countries such as Europe and the United States show that the total effective rate is over 95%��
