Apparatus for the treatment of skin wounds
First Claim
1. An ambulatory apparatus for the treatment of psoriasis skin wounds which comprises:
- a lamp possessing a narrow beam light with a high intensity for emitting ultraviolet and infro-red rays to the skin to be treated;
a glass lens which receives the rays, and focuses the beam of the light, said glass leans completely removing residual radiation in the range of 300 to 330 nm;
a black filter for receiving and filtering said focused rays having a transmittance of about 0.5 in the UVA and substantially a zero transmittance from 370 nm up to 750 nm; and
a liquid light guide having a diameter in the range of between 2 to 10 nm for receiving said filtered rays, and directing said filtered rays toward an area to be treated said liquid light guide providing at least 70% transmittance in UVA and substantially zero transmittance above 750 nm.

Abstract
A method and apparatus for the treatment of psoriasis skin wounds are described. The method is based on the use of a short arc lamp having the capability of providing a narrow beam light source. The light source possesses a high intensity, the minimum irradiance applied being at least 1 mW/cm2 to be obtained by a light guide. The light guide is made from fused glass or an anaerobic liquid, with a diameter in the range of 2 to 10 mm and provides a transmittance of above 70%. The apparatus using this method, comprises a lamp selected from Xenon or Mercury-Xenon type, a glass lens, a black filter and a light guide having a diameter in the range of between 2 to 10 mm. It can be connected to a microprocessor, which by monitoring the time of treatment, delivers the correct dose of light.
