The narrow-wave UVB 311nm narrow-wavelength UVB UVB is emitted by a dedicated lamp. The efficacy is determined.

Patients should study hard, learn from the instructions, and ask experts. It is best to learn from professional dermatologists and nurses.

Prevention and treatment of injury, radiation transition!

1. Look at the base of the machine and see that there is a label. If the machine you purchased has an irradiation intensity of 11.00mw/cm2, turn on the power switch.

2. Set the irradiation time: If the initial irradiation dose is set to 0.2 J/cm2, the initial irradiation time can be calculated according to the following two methods:

1) Calculation method: according to the formula: irradiation time = irradiation dose / irradiation intensity irradiation time = 200mJ / cm2 / 11.00mw / cm2 = 18s 2) In the specification table method: according to "usual irradiation dose / intensity / Time time table, directly check the irradiation time. See the table below for details. There is a large table in the opening manual, and the left side is the intensity of each exposure. Find the number corresponding to your device horizontally. If it is 11.0mw/cm2, it corresponds to the radiation dose 200, and find 0:18, which means 0 minutes and 18 seconds.

3, with goggles, appropriate shielding around the white class,

4. Gently attach the lamp baffle to the skin or psoriasis lesions. Insufficient illumination too far, too close will be printed out by the baffle.

5 Press the work button to illuminate

6, by the time, automatically stop taking photos. Or as many as planned, stop seeing when it is time. Do not extend the time yourself to prevent excessive exposure and is not good for treatment.
