International ClassA61N 005/06Foreign Application Priority Data1994-01-20 SEAbstractA device for the external medical treatment with the aid of light, including a light emitting element which is intended to lie against or be held close to a wound or sore on the body of an individual, and a drive arrangement for driving the light emitting element, wherein the light emitting element includes light emitting diodes or like devices and is constructed to emit infrared light. The arrangement (8, 9, 19) is constructed to cause the light emitting element (1) to emit infrared light in a first stage for a first predetermined length of time and thereafter to emit visible light in a second stage for a second predetermined length of time. The drive arrangement (8, 9, 10) is also constructed to cause the light emitting element (1) to pulsate the emitted infrared light and the emitted visible light respectively in accordance with a predetermined series of pulse frequencies over the predetermined time periods. The drive arrangement is constructed to emit two or more series having successively rising frequencies F1, F2, Fn, where F1 is a fundamental frequency and where F2, Fn are multiples of the fundamental frequency.Other References
