Dermatology excimer laser premixed gas
As the most advanced instrumental technology for the treatment of vitiligo, psoriasis and leukoplakia, it was originally invented in the United States. As the most advanced treatment for vitiligo and psoriasis, the 308 nm excimer laser for clinical treatment of dermatology is a kind of excimer laser. That is, xenon chloride (XeCl) excimer laser, which is a continuous pulsed gas laser, has a wavelength in the UVB range, and the pulse width is generally about 10 to 30 ns. Clinically used laser emitters are Xtrac (PhotoMedex, USA) [4-6], Lambda Physics LPX105E [2, 3, 7, 8] and other types of emitters [9], often including XeCl gas systems, due to The XeCl dimer consists of an inert gas crucible (8 electrons in the outermost layer) and halogen chlorine (7 electrons in the outermost layer), which are present in a combined state upon current activation, and emit a pulsed laser. Different laser emitter parameters are slightly different. Take the Xtrac AL7000 as an example. The 308 nm laser has a pulse width of 30 ns, a repetition rate of 154 Hz, and a single pulse energy density of 2 to 3 mJ / cm2. The laser can be transmitted to form a square spot of 2 cm × 2 cm. During the treatment, the spot can be adjusted as needed or the appropriate dose can be selected to achieve the best therapeutic effect. In the clinical use of various types of laser transmitters are easy to operate, the operator can hold the hand, the handle only moves on the skin lesions, evenly irradiate all skin lesions, can also be fixed in a part of the irradiation for a period of time, moved to the adjacent part.
The important consumable for exciting 308 nm excimer lasers is XeCl premixed gas, which is essentially Xe, HCl, Ne and other gases premixed in specific proportions for specific brands and models. At present, PUREGAS can provide XeCl premixed gas for dermatological excimer laser equipment of almost all brands on the market.
