Abstract

A phototherapy apparatus intended for the treatment of psoriasis comprising a dielectric-discharge excimer lamp with a spectrum which has a well-defined peak in the wavelength range around 308 nm; the lamp is mounted on a hinged or manoeuvrable arm supported by a stand.

Claims

1. Phototherapy apparatus for the treatment of psoriasis, characterized in that it comprises a dielectric-discharge excimer lamp, with a spectrum which has a well-defined peak in the range of wavelengths around the wavelength of 308 nm.

2. Apparatus according to claim 1, characterized in that the dielectric-discharge excimer lamp is equipped with reflector and optical system able to ensure a substantially uniform density of energy in the desired band, at a distance of about 10-30 cm, on the skin of the patient to be treated.

3. Apparatus according to at least claim 1, characterized in that it comprises a stand, an arm for the lamp which can in any case be maneuvered and fixed in the positions desired in each case and extends from the stand so as to arrange the lamp in a suitable position with respect to the surface of the skin of the patient to be treated.

4. Apparatus according to at least claim 1, characterized in that it comprises a selective sensor for stabilizing in each instant the emission intensity in the spectrum range around 308 nm.

5. Apparatus according to claim 1, characterized in that it comprises a sensor for the flow of the cooling liquid, in order to prevent temperature fluctuations of the lamp.

7. Apparatus according to claim 2, characterized in that the dielectric-discharge excimer lamp is equipped with reflector and optical system able to ensure a substantially uniform density of energy in the desired band, at a distance of about 10-30 cm, on the skin of the patient to be treated.

6. Apparatus with excimer lamp, for the treatment of psoriasis, all of which as described above and shown by way of example in the accompanying drawing.
