1. An element of a phototherapeutic device comprising an element in the form of a flexible head made of optical fiber with a core for transmitting light, wherein the element in the form of a flexible head includes a proximal end and a distal end, wherein the diameter of the proximal end is larger than the diameter of the distal end, and the proximal end is bent to provide convergence of light entering the element in the form of a flexible head through the proximal end； an elastic tubular coupling for mechanically attaching a flexible head element to a light source, wherein the coupling includes a proximal end with a hole and a distal end with a hole, the proximal end being configured to stretch and mechanically attach to the light source； an element in the form of a flexible head made of optical fiber is partially located inside the sleeve so that the distal end of the element in the form of a flexible head made of optical fiber extends in the distal direction uu through an opening in the distal end of the sleeve, and the proximal end of the element in the form of flexible head of the fiber was positioned inside the sleeve between the proximal and distal ends of the sleeve, thus locating element in the form of flexible head of the fiber near sveta.2 source. An element of a phototherapeutic device according to claim 1, wherein the element in the form of a flexible fiber optic head is formed as a solid part. The phototherapeutic device element according to claim 1 or 2, wherein the element in the form of a flexible fiber head has a rough outer surface configured to allow part of the light passing through the core to be diffused through1. Элемент фототерапевтического устройства, содержащийэлемент в виде гибкой головки из оптоволокна с сердечником для передачи света, причем элемент в виде гибкой головки включает проксимальный конец и дистальный конец, при этом диаметр проксимального конца больше диаметра дистального конца, и при этом проксимальный конец изогнут для обес
