ABSTRACT:
The present invention relates to apparatus for external medical treatment with light, and more specifically light that will alleviate and/or cure different sicknesses, illnesses, diseases, etc., hereinafter referred to as health disorders.
It has been found that infrared light has a favourable effect in this regard.
Swedish Patent Specification No. 502 784 teaches apparatus for external medical treatment with light, comprising a light-emitting device which is intended to lie against or be held in the close proximity of the body of an individual, and drive means for driving the light-emitting device, wherein the light-emitting device includes light-emitting diodes or corresponding light-emitting elements and is adapted to emit infrared light. The invention according to this patent is mainly characterized in that the drive device is adapted to cause the light-emitting device to emit light over a predetermined period of time in a first stage, and thereafter to emit visible light over a second predetermined period of time in a second stage; and in that the drive device is adapted to cause the light-emitting device to pulsate the emitted infrared light and the visible light respectively in accordance with a predetermined series of pulse frequencies.
It has been found that such apparatus can be used very successfully in the treatment of other disorders and injuries, for instance injuries sustained in sporting activities, pulled or strained muscles, muscular pain, joint pains, headaches, different inflammatory conditions, different skin complaints, such as acne, back pains, etc., provided that the light is emitted in a certain way. Treatment with light has a favourable effect on the healing of injuries and will alleviate and/or cure various health disorders.
Thus, it is realized that treatment with light in which a certain light is emitted in a certain series of frequencies will have a significantly greater effect with respect to shortening the time taken to cure or alleviate a health disorder.
It has also been found that treatment with solely one or more monochromatic lights other than infrared light, such as visible light of different colours, emitted in accordance with a certain pulse frequency give a very good treatment result.
The present invention is based on the insight that the pulse length of emitted pulsating light of a given pulse frequency has a great effect on the result of the treatment.
The present invention thus relates to apparatus for external medical treatment with light, wherein the apparatus includes a light-emitting device which is intended to lie against or to be held in the close proximity of the body of an individual, and a drive device for driving the light-emitting device, wherein the light-emitting device includes light-emitting diodes or corresponding elements and is adapted to emit monochromatic light of a first wavelength, wherein the drive device is adapted to cause the light-emitting device to emit said monochromatic light over a predetermined first time period in a first state, and thereafter to emit selectively monochromatic light of a different wavelength to the first wavelength over a second predetermined time period in a possible second stage, and wherein the drive device is adapted to cause the light-emitting device to pulsate said emitted light in accordance with a predetermined pulse frequency or series of pulse frequencies over said time periods, and wherein the apparatus is characterized in that the drive device is adapted to cause the light-emitting devices to emit said pulsating light with a pulse length that lies within an interval of about 60% to 90% of the time between respective start edges of two mutually sequential pulses.
