The best-known form of the disease is referred to as "acne vulgaris", which most of the afflicted people suffer from.

Description
Device for planar pulsed magneto-light therapy of acne
Field of the art
The invention concerns a device for pulsed magneto-light surface therapy of acne, formed by a system of switches, to which a combined applicator is connected.
State of the art
Acne is a chronic skin disease caused, among other things, by excessive production of sebum and manifested in the form of pimples, papules and perceptible spots. Sebum is produced in sebaceous glands and conveyed via excretory ducts to the skin surface. If for one reason or another the sebum cannot flow out freely, it accumulates in the gland and can cause an inflammation. Most acne types are inflammatory and appear during adolescence in particular. Acne affects 85% of the world population at the age of 12 to 24, and the disease may continue until adulthood. The best-known form of the disease is referred to as "acne vulgaris", which most of the afflicted people suffer from. It appears most frequently on the neck and face but also on the shoulders, chest and back. The disease can be considered grave in that it has an impact on young people's psyche and can lead to the inferiority complex and reluctance to communicate with other people.
There are many methods for the therapy of acne :which make use of the biochemical or biophysical therapy or their combination. Devices for biophysical therapy employ in most cases pulsed low-power lasers producing red or blue light. For the combined biochemical and biophysical therapy, one of the photo-serisitizers, from the porphyrin group in particular, is applied to the skin. After th application of light whose wavelength is in the region of 630 nm, which is one of the peaks of the spectral characteristic of porphyrins, free radicals get released, i.e. there is a photodynarhic reaction. This reaction leads to an almost necrotic decay or destruction of the undesirable tissue while the healthy tissue remains unaffected. The porphyrins used have also a signific nt effect on bacterial flora, one of the causes of ache;
If the therapy of acne begins immediately in its early phase, a more complex stage of the disease can be prevented, when cysts -are formed under the skin that result in scars which are difficult to remove. In addition to devices designed for the therapy of acne, there are also devices and methods aimed at removing such scars. t ! . η - -.
One of the possible therapy Methods is pulsed low-frequency magnetotherapy/ he essence of this method consists in the induction and force effects of variable magnetic field on the appearance and motion of electrically charged particles in the dissociated medium of
human tissue. Owing to the;; variable magnetic fields the permeability of intercellular membranes increase and so does the supply of nutrients and oxygen to the cells, and the removal of the products of metabolism is improved; Since a living organism is mostly diamagnetic, magnetic field can penetrate it without limitation. This fact, however, limits the therapy in the region of cranium, in addition to other limiting contraindications, because variable magnetic field can stimulate undesirable phenomena in the brain. Present-day devices have applicators, i.e. magnetic field exciters, in the fdrm of one or more big coils of insulated conductor, and the generated field penetrates deep below the surface of the organism. On these grounds it is almost ruled out to use pulsed magnetic field in the therapy of skin diseases on or near the head.
Another possible therapy method is pulsed non-invasive phototherapy. The substance of this method consists in
in the optic frequency band, produced by low-power light emitting diodes (lasers) drid focused on a relatively srnalla a of the surface of the organism. In addition to a negligible heat 'effect, this field has a . pronounced biochemical effect that supports Cell regeneration, arid 'also anti-inflammatory arid arialge c ingle-laiser

Summary of the invention
The above drawbacks of the state of the art are solved by means of a device for planar pulsed magneto-light therapy of acne containing a control unit and an applicator. On the functional surface of the applicator an array of light-emitting diodes is arranged in nests, and on the side opposite to the functional surface of the applicator an array of flat coils is arranged above the array of light-emitting diodes. Each flat coil is associated with a nest of diodes that is above the coil. The supply inputs of the flat coils are connected to the outputs of the circuit of flat coil switches while the nests of light-emitting diodes have their supply inputs connected to the outputs of the circuit of switches of the nests of light-emitting diodes. The first output of the control unit is connected to the control input of the circuit of flat coil switches, to the input of the circuit of common switches and to the first input of the signal multiplier while the second output of the control unit is connected to the second input of the signal multiplier, whose output' is connected to the control input of the circuit of nests of light- emitting diodes. This arrangement makes it possible to sequentially connect to the supply circuit each individual nest of light-emitting diodes together with the flat coil associated by the common switch circuit with each individual nest of light-emitting diodes. At the same time, this arrangement enables the power supply of nests of light-emitting diodes to be interrupted while they are being connected by the common switch circuit to the power supply circuit, with a frequency given by the signal multiplier: ί
In an advantageous embod ment of the device for planar pulsed magneto-light therapy of acne according to the invention a : signal multiplier is formed for the generation of a pulsed signal whose frequency is at least one order higher than the switching frequency of the circuit of flat coil switches for at least ten connections of the circuit of switches of the nests of light- emitting diodes in the course of a single connection of the circuit of flat coil switches. Thus in the time interval when the flat; coil generates a steady magnetic field the nest of light-emitting diodes arranged below the flat coil produces a rectangular light signal so that the number of connections and thus also the number of rectangular signals in the course of a single connection of the circuit of flat coil switches is at least ten.
In another advantageous embodiment of the device for'planar pulsed magneto-light therapy of acne according to the invention, the flat coils, the nests of light-emitting diodes and the size of supply current from dc supply source intended to improve the therapeutic effect are dimensioned for heating the applicator to a temperature ranging from 37°C to 45°C. !
In yet another advantageous embodiment of the device for planar pulsed magneto-light therapy of acne according to the invention the applicator is on the side opposite to its
functional surface provided with at least one non-conductive non-magnetic carrier pad for fixing the coils of the flat coil array and the nests of diodes of the light-emitting diode array, with the applicator being provided with a translucent protective layer on its functional surface. This type of therapy, using a combination of planar low-frequency pulsed magnetic field and high-frequency pulsed light field for therapeutic and cosmetic purposes has been tested clinically by the applicant over a long time with positive results.

In accordance with the program of the control unit 6, electric1 c'urfent from the dc supply 'source 9 is conveyed by the circuit 4 of the respective switches to fiat coils 11 and simultaneously by the circuit 5 to the nests of light-emitting diodes 12 of the applicator 1. At the time the current pulse passes through a certain flat coil 11, the nest of light-emitting diodes 12 disposed above the respective flat coil 11 is simultaneously supplied wifti a great number of current pulses. 1 ; The control unit 6 thus sequentially connects individual flat coils 11 or groups of flat coils ll, and at the time when tlie given individual flat coils 11 or groups of flat coils 11 are connected to the dc supply source ^ it triggers the signal multiplier 8, which with a frequency at least one or two orders higher than' the frequency of the pulsed supply current of flat coils 11 connects/disconnects the dc "supply source 9 to/from the flat coils 11 associated with the nests of light-emitting diodes 12. This results in that i a selected area of the surface^ of the applicator 1 the flat coils ll' or groups of flat coils ll are current-supplied and thusi act by
their magnetic field on that part of; the skin being treated which is adjacent to this activated part of the applicator 1, while at the time when these flat; coils 11 or groups of flat coils 11. are connected to the dc supply source- 9 . the same part of the skin being treated is also acted on by light from nests of light-emitting .;diodes 12 such that in the course of one pulse pf the magnetic field acting on the skin being treated this skin is being acted on by at least ten, preferably over one hundred light pulses. This is because it has been established that it is in particular the abrupt change in lighting in the course pf the magnetic field action that has healing effects on the skin being treated.
The array 3 of flat coils 11 and the array 2 of nests of light-emitting diodes 12 thus generate a sequential pulsed magneto-light field, which in view of the size, shape and location of flat coils 11 and nests of light-emitting diodes 12 can be regarded as planar with a small penetration depth. ; J;;÷ ° ; ,
Flat coils 11, nests of light-cniitting diodes 12 and the magnitude of supply current from the dc supply source 9 are dimensioned for the heating of applicator 1 to a temperature of 37°C to 45°C because it has also been found that commensurate heat increases the therapeutic efficacy.
Industrial applicability
