DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates to a device for healing wounds and sores with the aid of light, where, more specifically, the light facilitates healing of the wound or sore and accelerates the healing process.
2. DESCRIPTION OF THE RELATED ART
It has been found that the treatment of wounds and sores with the aid of light has a favorable effect on the healing process, such as to accelerate healing. This applies to both wounds in the form of continuity interruptions in normal tissue and such sores as pressure sores caused by violence, leg ulcers, burn injuries, etc.
It has been observed that infrared light has a favorable effect on the healing of wounds and sores.
SUMMARY OF THE INVENTION
The present invention is based on the understanding that light treatment effected by transmitting given light at given time intervals will give a significantly improved effect in the form of a shortened healing time. The present invention enables the time taken to heal a wound or sore to be halved in all essential in comparison with a healing process in which no treatment is given.
The present invention thus relates to a device for healing wounds and sores with the aid of light, this device 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 means for powering the light emitting element. The light emitting element includes light emitting diodes or the like and is intended to emit infrared light. The power means is constructed to cause the light emitting element to emit infrared light in a first stage for a first predetermined length of time, and thereafter to cause the light emitting element to emit visible red light in a second stage for a second predetermined length of time. The power means is also constructed to cause the light emitting element to pulsate the emitted infrared light and the visible red light respectively in accordance with a predetermined series of pulse frequencies over said predetermined time periods.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described in more detail, partly with reference to an exemplifying embodiment of the invention illustrate in the accompanying drawing, in which
FIG. 1 is a block schematic illustrating the device, and
FIG. 2 is a side view of a light emitting element.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1 and 2 illustrate a device for healing wounds and sores with the aid of light, said device including a light emitting element 1 which is intended to be placed against or held close to a wound or sore on the body of an individual. The light emitting element is shown from one side in FIG. 2 and from beneath in FIG. 1. This member includes a housing 5 which is provided with a transparent plate 6. Above the plate 6 there is located a surface 2 in which a number of light emitting diodes 3, 4 or corresponding devices are mounted. Thus, the light emitting diodes are intended to transmit light through the plate 6 when activated, i.e. when supplied with current through a cable 7. In use, the housing 5 is held so that the plate 6 will lie against the part of the body to be treated. The device also includes drive means 8, 9, 10 for driving the light emitting element 1. The light emitting element 1 includes light emitting diodes 3 or like devices which are constructed to emit infrared light. These diodes are marked with solid circles in FIG. 1.
According to the invention the drive means are provided to cause the light emitting element 1 to emit infrared light in a first stage for a first predetermined length of time, and then to emit visible red light in a second stage for a second predetermined length of time. Visible red light is emitted by means of light emitting diodes 4 or like devices. These devices are marked with hollow circles in FIG. 1. It is extremely important that the treatment is carried out in the order infrared light followed by visible light.
According to the present invention, the drive means are als
