Problems solved by technology

A disadvantage of the known system is that it provides a rather uneven radiation distribution over the target area
Another disadvantage of the known system is that it is a relatively spacious construction, which renders this design less suitable for application in plasters, because due to this, the known system makes the patient uncomfortable when wearing the known system

Embodiment Construction

[0024] figure 1A system 1 according to a first embodiment of the invention is shown. The system 1 comprises a plaster 2 and in a stacked position (ie on top of the plaster) the radiation device 3 is adhered to the plaster by means of a first adhesive 8 . The system 1 is secured to a human skin surface 5 , which defines a plane P, by means of a second adhesive 4 . The skin surface is injured, creating a wound which defines a target area 6 which is the area of ​​the outer top surface of the wound. The target area 6 is covered by the radiation transparent window 7 of the plaster 2 . The radiation device 3 includes a light guide 9 which is in optical contact with the window 7 through a coupling medium 17 such as transparent or semi-transparent adhesive, or a coupling glue such as silica gel, and is illuminated by the edge of the radiation source 10 . The radiation source and light guide are in optical contact with each other at edge 18, but optical contact is not required. The...

Abstract

The invention relates to a compact, comfortably wearable system (1) comprising a plaster (2) and a radiation device (3) in a stacked position on top of the plaster. The radiation device (3) comprises a light-guide (9) which is optically connected and edge-lit by a radiation source (10). The radiation source (10) is electrically connected to an energy source (11), which is stacked on top of the light-guide 9. A reflector (12) is provided to reflect radiation in the direction of a target area (6). Due to total internal reflection (TIR) inside the light-guide (9) and multiple reflections a spreading is obtained of each of the radiation rays (15) generated by the radiation source (10), which results in the target area to be evenly irradiated.

Description

technical field [0001] The invention relates to a system comprising a plaster and a radiation device according to the preamble of claim 1 . [0002] The invention also relates to plasters and radiation devices suitable for use in such systems. Background technique [0003] During wound healing, there are usually three phases, 1) the inflammatory phase, when the wound is covered with cloth after injury and bacteria are fought off by white blood cells; 2) the new tissue formation phase, when new tissue is produced and the wound begins to shrink, and 3) ) stage of tissue remodeling, when new tissue becomes mature scar tissue. It is known from the literature that radiation therapy (e.g. phototherapy) may be beneficial in any of the three phases, that is, because it can accelerate and enhance the wound healing process during the first two phases and it can Keeping the process under control during the final stages of tissue remodeling prevents the production of excess scar tissu...
