靶向紫外线光疗 308-NM 准分子灯 UVB 光疗 紫外线用于皮肤病 白癜风

Powerful Mini excimer laser 308nm   308-NM Excimer Lamp TS The 308-nm excimer lamp represents the latest advance in the concept of selective phototherapy, for Psoriasis and vitiligo attracting most attention. Induced rates of repigmentation seem to be higher than with narrowband UV-B. Moreover, the selectivity ofthetreatment prevents irradiation of healthy skin and limits unsightly tanning of surrounding skin. MANY STUDIES HAVE EVALUATED THIS NEW DEVICE IN A NUBER OF DERMATOLOGIC DISORDERS.   Introduction of the 308-nm excimer lamp The excimer lamp emits a wavelength of 308 nm produced using xenon and chlorine gases. These technical characteristics provide with many advantages over conventional phototherapies. High fluencies are possible, which can be useful in thick plaques of psoriasis. It is also possible to selectively turn the beam of light and thus to treat the specific area involved, sparing healthy skin. It is easier to reach areas that are usually difficult to treat, such as mucosa. The use of a monochromatic wavelength of 308 nm gives photobiological effects theoretically superior to those provided by NB-UVB, Stimulation of melanocyte migration and proliferation from progenitor niches located in hair follicles is certainly the major factor. This stimulation is due to the direct action of UV on melanocytes but also to the action of cytokines secreted by keratinocytes. Advantages of 308-nm excimer lamp Monochromatic beam of lighting, consistent high fluencies, reducing treatment sessions and cycles. Selectively treat a lesion while sparing surrounding healthy skin, with the specific treatment handler. Portable, easy lighting replacement, convenient for home use. Reasonable price, more suitable for individual use No needing of preheating, longer life of lighting lamp, low cost of consumables. Excellent Targeting Limited Spots size for small area. It easier to reach areas that are usually difficult to treat. Applicable symptoms: 1. Psoriasis 2. Parapsoriasis 3. Vitiligo 4. Relapse eczema 5. pityriasis rosea 6. atopic dermatitis 7. palmoplantar pustulosis 8. alopeciaareata 9. chronic skin ulcer 10. granulomafungoides 11. prurituscutanea
