Irradiation method of ultraviolet phototherapy instrument

The irradiation method of the ultraviolet therapeutic instrument is to hold the irradiation hand, open the baffle of the base, take out the connecting line between the irradiator and the base, hold the irradiation hand, and aim the ultraviolet tube at the affected part. Fixed irradiation: insert the handle of the illuminator into the groove of the base, and aim the ultraviolet lamp tube at the affected part; During the nursing period, you can take temporary leave in case of special circumstances. After irradiation, the number is displayed as "zero" and the lamp is automatically turned off. Complete the whole therapeutic growth of the irradiation instrument. If you want to use it again, the whole program must start from scratch, and the time controller has no memory function of setting the irradiation time last time. Please turn off the power switch after use, unplug the power plug, clean it and put it in the box.

The irradiation wavelength is 3 10 ~ 3 13 nm. The initial radiation dose of vitiligo patients was 0.2J/cm2；. . The initial radiation dose of patients with psoriasis was 0.3 J/cm2. . If the irradiation intensity of the machine you bought is 1 1.00mw/cm2, and the initial irradiation dose is set to 0.2J/cm2, then the initial irradiation time can be calculated in the following two ways: 1) Calculation method: According to the formula: irradiation time = irradiation dose/irradiation intensity = 200mJ/cm2//kl.

Please use it under guidance, and pregnant women should use it with caution. Those with a history of skin tumor and radiotherapy should use it with caution.

Tips: (1) For psoriasis, use water bath 15 to 20 minutes before irradiation to remove scales from the lesions; (2) Cover or use sunscreen to protect the area around the focus during irradiation; (3) Wear ultraviolet goggles to protect eyes during irradiation; (4) Avoid excessive sunlight in the irradiated area, and cover with clothes or use sunscreen when going out; (5) After irradiation, if obvious erythema appears on the skin, it should be adapted to extend the irradiation interval or reduce the irradiation dose;
