Description: A DEVICE FOR EXTERNAL MEDICAL TREATMENT WITH MONOCHROMATIC LIGHT The present invention relates to an apparatus for external medical treatment with the aid of light, and then more specifically with light that will alleviate and/or cure different diseases, illnesses, sicknesses, etc., hereinafter referred generally as health disorders. The Swedish Patent Specification No. 502 784 teaches appara¬ tus for external medical treatment with the aid of light. The device includes light-emitting devices which are intended to lie against or be held in the close proximity of the body of an individual, and means for driving the light-emitting device, said light-emitting device including light-emitting diodes or corresponding light-emitting elements. According to this prior publication, the treatment apparatus also includes a drive means which functions to cause the light- emitting device to emit monochromatic light over a predeter- mined period of time. The drive means is also adapted to cause the light-emitting device to emit pulsating light in accordance with a predetermined series of pulse frequencies. It has been found that apparatus of this kind can be used very successfully in the treatment of 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 liyhl 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. The present invention is based on the conception that treatment corresponding to acupuncture treatment can be effected with the aid of emitted pulsating light that has a certain pulse frequency, wherein the light replaces conven¬ tional acupuncture needles. The present invention thus relates to apparatus for external medical treatment with the aid of light, wherein the appara¬ tus includes a light-emitting device which is intended to be placed against or held in the close proximity of an acupoint on the body of an individual, and a light-emitting device drive means, wherein the light-emitting device includes light-emitting diodes or corresponding light-emitting elements, wherein the light-emitting device is adapted to emit monochromatic light of a predetermined wavelength, wherein the drive device is adapted to cause the light- emitting device to emit said monochromatic light over a predetermined period of time, and wherein the drive device is adapted to cause the light-emitting device to emit light that pulsates in accordance with a predetermined pulse frequency. The apparatus is characterized in that the drive device is operative in causing the light-emitting device or elements to emit said pulsating monochromatic light at a pulse repetition frequency in one of the ranges 5 Hz to 9.5 Hz, 22.2. Hz to 36.0 Hz or 273.8 Hz to 324.0 Hz. The invention will now be described in more detail with reference to exemplifying embodiments and also with reference to the accompanying drawings, in which - Figure 1 is a block schematic of the inventive apparatus, - Figure 2 is a side view of a light-emitting device; and - Figure 3 illustrates a modified construction of an inven¬ tive apparatus. Figures 1 and 2 illustrate apparatus for external medical treatment with the aid of light. The apparatus includes a light-emitting device 1, which is intended to lie against or to be held in the close proximity of the body of an individu- al. Figure 2 shows the light-emitting device from one side, while Figure 1 shows the element from beneath. The light- emitting device includes a housing 5 which is provided with a transparent plate 6. Located beneath the plate 6 is a surface 2 on which a plurality of light-emitting diodes 3, 4 or corresponding light-emitting elements are mounted. The light-emitting diodes send light through the plate 6 when the diodes are energized, i.e. supplied with current through a cable 7. In use, the housing 5 is held so that the plate 6 will lie against the relevant part of the body. The apparatus also includes drive means 8, 9, 10 for driving the light- emitting device 1. The light-emitting device 1 may include light-emitting diodes 3 or corresponding means for emitting infrared light. These diodes or the like are marked with solid circles in Figure 1. The drive means 8, 9, 10 are adapted to cause the light- emitting device 1 to emit monochromatic light of a given wavelength over a predetermined time period. The drive means may also be adapted to emit monochromatic light of a wave- length different to the first-mentioned wavelength over a second predetermined time period, in an optional second stage of the treatment. Visible light is emitted with the aid of light-emitting diodes 4 or corresponding elements. These diodes are marked with hollow circles in Figure 1. The drive means 8, 9, 10 are also adapted to cause the light- emitting device 1 to emit pulsating light in accordance with a predetermined pulse frequency or a series of pulse frequen¬ cies over predetermined time periods. The drive means include a computer 8 which functions to control drive circuits 9, 10, to which voltage is applied for driving the light-emitting diodes via conductors 11, 12. The computer and drive circuits are of an appropriate known kind. Connected to the drive means is a keyboard 13 by means of which the operator can enter drive means control data for actuating the light-emitting device in a desired manner. The apparatus will also conveniently include a display 14, on which the settings made through the keyboard are displayed. Infrared light-emitting diodes 3 are preferably semi-conduc¬ tor diodes of the GaAs kind (Gallium arsenide). The light- emitting diodes 4 that emit visible light are also preferably of the GaAs type. For instance, the number of light-emitting diodes included in the light-emitting device may be such that the infrared light-emitting diodes will together generate a light power of 1800 milliwatts, and the diodes that emit visible light may each have a power of 3000 millicandela. According to one embodiment of the invention, the light- emitting device 1 includes red light emitting diodes 4 that emit visible light at the wavelength of 660 nanometers and/or infrared light emitting diodes that emit light at the wavelength of 950 nanometers. In another embodiment of the invention, the light-emitting device 1 includes light-emitting diodes 4 that emit a substantially monochromatic visible light in one of the colours violet, blue, yellow, orange, red or green. The subject matter described above with reference to the accompanying drawings is essentially also found described in the aforementioned patent specification. According to the invention, the drive means 8, 9, 10 are adapted to cause the light-emitting device or elements to emit said pulsating monochromatic light at a pulse repetition frequency in one of the ranges 5 Hz to 9.5 Hz, 22.2 Hz to 36.0 Hz or 273.8 Hz to 324.0 Hz. It has surprisingly been found that the inventive apparatus can be used for acupuncture treatment in a manner correspond¬ ing to acupuncture treatment with the aid of conventional acupuncture needles. It has also surprisingly been found that the treatment, i.e. stimulation of the acupoints, is effected much more quickly than conventional acupuncture. Normally, each acupoint need only be treated for a period of about one minute, as compared with treatment for from about five minutes to up to an hour with conventional acupuncture. Furthermore, the patient need not feel any pain. The present invention thus represents considerable steps forward in the art. Treatment is effected in the same way as conventional acupuncture, although, with the difference, that the light-emitting device is placed over the acupoint in question instead of needles, and the therapist then activates the light-emitting device such as to emit desired monochro¬ matic light in accordance with a desired pulse repetition frequency. Because the light-emitting device has a relatively large irradiating surface area, the acupoint in question can be found easily. It will be understood that the illuminating, or irradiating, surface area of the light-emitting device can be adapted so that a smaller surface can be made illuminat¬ ing, or irradiating, for treatment at acupoints which are relatively close together, so as to avoid treating acupoints that shall not be treated when treating a specific acupoint. Three ranges of pulse repetition frequencies have been mentioned in the aforegoing. The intermediate range of 22.2- 36-0 Hz is preferably used against so-called specific acupoints. The highest range is used for so-called weighted acupoints found on feet and hands. The lowest range is used for so-called reflex points, which are found on the ears. The invention is not concerned with the question of which of the aforesaid monochromatic light shall best be used for different treatments. The wavelength of the light is chosen to give the intended treatment effect, depending on the health disorder or injury to be treated and also on which acupoints shall be included in the treatment. The drive means includes selector means of known kind with which the operator can choose a pulse repetition frequency that lies within each of said ranges. For instance, the selector means may include the aforesaid keyboard by means of which desired pulse repetition frequencies are set. The chosen setting will suitably be shown in the display. According to a preferred embodiment of the invention, the light-emitting device includes at least two separate light- emitting elements 1, 15; see Figure 3. The light-emitting elements are adapted to emit monochromatic light of mutually the same wavelength. Both elements are connected to the drive means 8, 9, 10. When more than two light-emitting elements are included, as indicated with the light-emitting element 16 shown in broken lines in Figure 3, all said elements are connected to the drive means. The drive means functions to cause each of the light-emitting elements to emit the monochromatic light synchronously in accordance with a predetermined selected pulse frequency. This embodiment thus enables two or more acupoints to be treated simultaneously. According to one embodiment, the light-emitting device is adapted to emit monochromatic light of different wavelengths. In this case, the drive means function to cause the light- emitting device to emit solely light of one wavelength at each time point. The drive means is provided with a selector means of known kind, for instance a selector means in which the operator can enter, and therewith select, a desired wavelength. Selected wavelengths will conveniently be shown on the display. It will be apparent that the illustrated and described light- emitting device can be modified. For instance, the device may have form of a light pen that emits a light point having a diameter of, e.g., 0.5 cm to 2 cm. It will be understood that the invention is not restricted to the aforedescribed and illustrated exemplifying embodi¬ ments thereof and that modifications and variations can be made within the scope of the following Claims.
