Light guide device for phototherapy
First Claim
1. A light guide device for phototherapy, comprising an optical fiber light guide having a light guiding strand, a light reflecting envelope and a protective envelope, and a light scattering member provided at a distal end of the optical fiber light guide, characterized in that the protective envelope (4) of the optical fiber light guide (1) protrudes beyond an end face (6) of the distal end of the optical fiber light guide (1) and defines a closed space with the end face (6), and in that the light scattering member (5) is made of an optically turbed medium (7) which is contact with the end face (6) of the optical fiber light guide (1) and which fills up the entire closed space.

Abstract
A light guide device for phototherapy has an optical fiber light guide (1) and a light scattering member at its distal end. A protective envelope (4) of the light guide (1) protrudes beyond an end face (6) of its distal end and defines with this end face (6) a closed space which is filled up entirely with an optically turbid medium (7) which defines the light scattering member (5).
