    15 20 25 30 35 The device has also been used with great success for wound treatment, for example for diabetic foot ulcers, and in elderly care and further in aesthetics and equestrian sports.
    There is thus an insight that light treatment by emitting certain light in certain frequency series gives a significantly increased effect in the form of shortening the time for a disease to cure or alleviate a disease.
    Since the light treatment is assumed to have an effect already at the cellular level, it is desirable to use a dynamic light image and that the entire area of the body to be treated receives an equal amount of light over time. For example, those who are treating a problem with the mentioned devices, described in Swedish patent 502 784 above, in order to meet the requirement for a dynamic light image and as large an amount of light over time as possible, must perform an oscillating movement with the light emitting means when it abuts or is held close to the area of the body of the individual to be treated. The reason for this is that the LEDs which are arranged at the bottom of the light emitting member have a certain geometric extent, which is why there is a certain distance in order to be whole and of different kinds, between two nearby LEDs of the same type. the area to be treated must be exposed to as even lighting as possible, the light-emitting body must therefore be moved back and forth over the area.
    Since a treatment typically takes about two to ten minutes, it is very burdensome for the staff to perform such a treatment often.
    It is therefore previously known to arrange an eccentric device between the housing of the light emitting means and the plate which in this case carries the LEDs, see Swedish patent 515 992. the eccentric device comprises a first part which is fixed h: docworkkmsökstextdoc, Arranged relative to the housing and a second part which is connected to the LED plate and a spring which prevents rotation of the plate. An electric motor is arranged to drive the eccentric device, whereby the plate with the LEDs performs an oscillating movement.
    It is also previously known to arrange an electric motor fixed relative to the housing of the light emitting member and which is connected to the LED plate via a drive shaft, 515 991. a rotating movement, see the Swedish patent Hereby the plate with the LEDs will perform whereby it is obtained overall. a more even lighting and increased cellular response in the area to be treated.
    A disadvantage of the devices described above for achieving the required oscillating or rotating movement is that they are both based on a mechanically generated movement pattern where expensive and relatively heavy components are built into the device. This in turn leads to higher production costs, increased wear and thus increased costs for maintenance and the risk of complaints. Requests for as friction-free components as possible lead to tight tolerances during manufacture and strict requirements when assembling the moving parts.
    A further disadvantage of today's equipment for creating an even lighting is that the mechanically generated movement pattern takes place in a plane and thus limits the geometry of the diode plate to such a plane. If the illuminated surface is also flat, this is not a problem, as even and sufficient illumination is obtained over the surface. But in reality, the surface to be treated is rarely flat. There is therefore a desire to increase the degree of freedom with respect to the geometric shape of the diode plate so that it becomes more adapted to the body part to be treated.
    The present invention solves this problem by giving the diode surface a curved shape and replacing the mechanical rotation with an electronically generated movement pattern. An electronically generated movement pattern provides significantly greater freedom with respect to the desired movement along the body part to be treated and does not include any mechanically moving parts. It provides an opportunity to design the diode plate into a shape that is adapted to the body part to be treated.
    It also provides an opportunity for a more arbitrary movement along the body part to be treated.
    The present invention thus relates to a device for medical treatment externally by means of light. The device comprises a light emitting means arranged to abut against or held close to the body of an individual and a drive device for the light emitting means, which light emitting means comprises LEDs or the like which LEDs are arranged to emit light in different wavelength ranges, where the drive device is arranged to control the light emitting means for emitting one or more lights during one or more predetermined times and arranged to pulsate emitting said light according to a predetermined pulse frequency or series of pulse frequencies during said times, said light emitting means comprising a housing and a surface supporting the LEDs and there the LEDs are arranged, for example, in matrix form on said surface so that there is a certain distance between two adjacent LEDs.
    According to the invention, the diode surface has a curved shape for adaptation to the body part to be treated and an electric drive circuit is arranged for sequential or arbitrary control of the LEDs, which drive circuit is connected to one or more of the individual LEDs and arranged to turn them on and off so that a moving light image appears over the curved LED surface.
    According to an advantageous embodiment, the LEDs are arranged in matrix form in rows and columns on the curved surface. In the following, an exemplary embodiment of the invention will be described in more detail with reference to the accompanying drawings, in which - Figure 1 shows a previously known light emitting means in a side view, - Figure 2 shows a light emitting means according to the invention in a side view, - Figure 3 schematically shows a block diagram of a device according to the invention - Figure 4 schematically shows some different examples of suitable diode surfaces, and - Figure 5 shows an example how the surface mounted LEDs can be applied Figure 1 generally shows a device for medical external treatment by means of light comprising a light emitting means 1 arranged to abut against or held close to the body of an individual, for example an arm or a leg 8. The light emitting means is shown in the figure from the side and comprises a housing 2 provided with a transparent disc 3. Under this disc 3 inside the housing there is a surface 4 in which a number of LEDs 5,6 are mounted in matrix form, see figure 3. The LEDs 5,6 are arranged to emit light through the disc 3 when they are supplied with current via a cable 7. In use, the housing 2 is held so that the disc abuts or reaches the relevant body part of e.g. person whose wound injury is to be treated. Furthermore, the device comprises a drive device for the light emitting means, see the block diagram in Figure 3, where the light emitting means 1 is also shown from below. The drive device is arranged to control the light emitting means 1 to emit different monochromatic lights of different wavelengths during different predetermined times and to emit said light pulsating according to a predetermined pulse frequency or series of pulse frequencies during said times. The parts of the invention which have been touched upon so far are not described in more detail here, but reference is made to the above-mentioned Swedish patents. As shown in Figure 1, the surface 4 in which the LEDs 5,6 are mounted is substantially planar. This is due to the previously mechanically generated movement pattern. As can be seen from the figure, the lighting then only becomes optimal on a small part of This means that the body part in question, indicated by the arrow B. the equipment must be moved often around the body part.
    By generating the diode motion electronically, it is possible to design the diode surface 4 'curved as shown in Figure 2.
    In this way, the diode surface can be adapted more to the body part to be treated. In use, the housing 2 is held so that the curved disc 3 'abuts or close to the relevant body part. Then a larger part of the body part can be illuminated as indicated by the arrow B '.
    The drive device for the light emitting means comprises on 12 which drive circuits are supplied with signals from the computer to in turn edge a computer 10 for controlling drive circuits 11, drive the LEDs via the conductor 7. To the drive device or computer is connected a keyboard 13 by means of which the operator the controller can key in data to thereby control the drive device to control the light emitting means in the desired manner.
    Conveniently, there is also a display 14 for displaying the settings made by means of the keyboard 13. The device further comprises an electric drive circuit arranged for sequential or otherwise predetermined control of the LEDs, which drive circuit is connected to the individual LEDs and arranged to switch the LEDs on and off, for example in sequence so that a moving light image appears over the LED matrix. surface. Figure 3 schematically shows this drive circuit connected to the rows and columns of the diode matrix. According to an advantageous embodiment, the drive circuit comprises a separate drive circuit 15 arranged to control one or more rows of LEDs in the matrix and a separate drive circuit 16 for controlling one or more columns of LEDs in the matrix. The drive circuits 15,16 are connected to the computer 10 and a suitable power supply (not shown). The computer processor can, by default, control the drive circuits for rows and columns in the diode array so that a suitable moving light image appears over the surface of the diode array. By turning the individual LEDs on and off in sequence, the light intensity travels across the surface. A light pulse / light image appears and an arbitrary movement, for example a circular movement, can be generated, regardless of whether the diode surface is flat or curved. This movement replaces the previously mechanically generated movement of the light emitting member which for mechanical reasons was limited to flat surfaces.
    Figure 4 schematically shows some examples of suitable surface geometries adapted for the treatment of different body parts: single-curved surface in figure 4a, double-curved surface in figure 4b, tubular surface in figure 4c and flexible, body-shaped surface in figure 4d.
    The surfaces can be built up of a preformed, rigid material, but they can also advantageously be built up of a flexible material. In the latter case, the lighting device may be in contact with the body part in question and the shape of the diode surface is determined by the external shape of the body part. In the case of preformed, rigid diode surface, this is kept at a suitable distance from the body part during the treatment.
    Figure 5 shows an example of how the surface-mounted LEDs 5, 6 can be applied in a flexible "light mat" 17 with a shape that is adapted to the current body part. The material consists, for example, of a soft plastic material which has a certain "stretch". The LEDs can be equipped with built-in optical lenses to provide the desired light image for the individual LEDs compared to the scattering angle they have in them. The LEDs with optics are cast in a translucent material 18, soft plastic material such as polyethylene etc., which acts as a spacer element so that a suitable distance between the LEDs / optics and the current body part is maintained. In this way, the pillow 17 can be fixed to the body. via flexible PCB, the LED mat, easily laid against or tightened The LEDs are connected to the drive circuits flexible printed circuit board, so-called flexiboard 19. h: docworkkmsearchstextdoc, 2010-12-03 100233EN 10 15 20 25 30 Thanks to the increased degree of freedom with regard to the shape of the diode plate, a treatment equipment can be provided with several different lighting fixtures for different applications. The equipment may, for example, comprise a number of fixed, predetermined shapes in case one does not want physical contact with the body during the treatment operation, and one or more flexible diode mats, of model sock, belt, armband, bandage, blanket, in case the body part in question can determine the shape by contact.
    The invention is not limited to the above-mentioned embodiments but can be varied within the scope of the appended claims. The invention is thus not limited to the diode shapes described above but can be applied to all kinds of preformed or flexible bandages and bandages for medical treatment externally. The invention is also not limited to any particular layout or any specific movement pattern of the surface mounted LEDs. It is further understood that the LEDs may be distributed over the entire curved diode surface or only over a part thereof. h: docworkkmsökingstextdoc, 2010-12-03 100233EN
