Abstract

In the arrangement for magnetic field therapy of the human skin, at least one treating element is connected as "horseshoe matrix" and/or one treating element is connected as "lobe matrix" respectively optionally or simultaneously to a control device with a frequency stepping switch. The "horseshoe matrix" is assembled in the form of a matrix from horseshoe-shaped electromagnets consisting of the ferromagnetic material and the coils, so that magnetic south poles and north poles alternate in the manner of a chessboard. The "lobe matrix" is assembled analogously, but each magnetic pole consists, for its part, of a matrix having a plurality of magnetic poles which are arranged in parallel and have a direction effect.

Description

Arrangement for magnetic field therapy of the human skin

The invention relates to a medical magnetic field therapy device, used for the treatment of human skin and subcutaneous tissue shall be.

Magnetic therapy is well known and has great advantage Depth effect. Should only a cosmetic or dermatological skin treatment or Treatment of the subcutaneous tissue achieved without affecting deeper layers the alternating magnetic field strength must preferably be concentrated on the surface stay. If this is not observed, undesirable side effects such as E.g. nervousness in the treated patient.

In the case of the well-known magnetic field therapy devices that are also used in the Cosmetics are used, frequency modulation (wobbling, So-called. Wave swing) used because the therapeutically effective oulsationsfre frequencies of the magnetic field depend on the indication and the type of patient and the practitioner should not be expected to find the right frequencies. the Therapeutically useful frequencies are only used for a very short time the frequency modulation effective.

From the German utility model Gr 7923751 is a magnetic one Dipole matrix known, which has a particularly great depth effect of the magnetic lines of force achieved by close-lying, parallel-connected rod-shaped electromagnets. Rir the intended application, this arrangement has the technical disadvantage that it is useless Magnetic lines of force in the room are wasted, which has poor efficiency result from the arrangement.

As an arrangement that, conversely, has a surface effect, the horseshoe magnet is known, but it only has a spatially small area in its iitift gap interspersed with strong magnetic lines of force.

The disadvantage of the known arrangements is therefore poor efficiency both as a result of excessive force line spread and as a result of only short-term presence the correct pulsation frequencies, which requires a long total therapy time, so it is uneconomical.

The present invention has as its object an arrangement to construct that does not have these disadvantages, but only a short total therapy time requires and over a larger area a concentrated magnetic field in this area generated perpendicular to this surface in the direction of the remote from the arrangement Side as rapidly as possible (as you progress in this direction) in field strength.

It is necessary that the treatment elements when used in the face area at a certain distance of a few centimeters from the skin be positioned, while on other parts of the body a direct support on the Clothing can be tolerated.

Thus three tasks have to be solved: 1. Flat magnetic field less Penetration depth (about one centimeter) when the treatment element is placed directly tes on the body or clothing.

2. Club-shaped magnetic field with a depth of a few centimeters when using the treatment element at a respectable distance from the skin.

D. The longest possible exposure time to fixed therapy frequencies.

The tasks set are achieved according to the invention as follows: 1. Structure of a matrix from not too dense, but rather far enough apart magnetic dipoles with alternating polarity, hereinafter referred to as the horseshoe matrix.

2. Structure of a matrix like 1., but with alternating polarity magnetic dipoles themselves consist of tightly packed matrices with the same polarity, hereinafter referred to as the "lobe matrix".

3. Replace the wobble (? Frequency modulation) with step \ #eise Change in therapy frequency at which each frequency - hereinafter referred to as frequency level " called - acts for a certain time and then switched to the next will. This arrangement is referred to below as the "frequency step circuit".

The proposed solutions to the given tasks are based on explained by figures.

Figure 1 shows the overall arrangement in principle: To the control unit (1) The treatment elements are either at the same time or alternatively the horseshoe matrix (2) or club matrix (3) connected, with each treatment element also multiple may be present e.g. two horseshoe matrices (2) or. two club matrices (3).

Figures 2 and 3 show the principle of the horseshoe matrix (2). This sets consist of several garland-shaped lines (Fig. 2), consisting of one ferromagnetic material (4) - for example a bundle made of isolated from each other Iron wires, strands or strips - whereby the ferromagnetic material (4) consists of consists of several roughly horseshoe-shaped or U-shaped curved sections and each one second U-leg contains a coil (7) and the coils (7) are all polarized the same, so that the U-Schenlçel alternately have a magnetic south pole (5) and north pole (6) represent when the coils (7) with direct current and / or pulsating direct current get excited.

Several such lines according to Fig. (2) are to form a horseshoe matrix (2) according to Fig. (3) housed in a cup-shaped ferromagnetic housing (8), with at least one of the U-legs at the edge without a coil (7) magnetically with the housing (8) is connected, so that the upper edge of the housing (8) itself a magnetic pole (in Fig. 3 south pole) represents. The opposite side of the case (8) is magnetically closed, so that backwards (in Fig. 3 perpendicular to the Plane of the drawing) no magnetic lines of force can escape.

Figure 4 shows the principle of the lobe matrix. Several (at least two, as shown in Fig. 4) wires, strips or strands made of ferromagnetic material (4) used in parallel, with one of the magnetic leg sides (in Fig. 4 north pole leg) each contains a separate coil (7) and here, too, all coils (7) in parallel or are connected in series or in groups in such a way that they have the same polarity. At the open ends of the U-legs create a directional effect due to lines or flatriax effects Magnetic field (in Fig.

4 up), which is caused by the neighborhood of the reversely polarized magnetic poles does not have too great a depth effect, but club shape.

A housing (8) can also be used here.

Figure 5 shows the inside of the control unit (1) in principle. The generator (9) for pulsating direct current, which forms the horseshoe matrix in the treatment elements (2) and / or lobe matrix (3) contained coils (7), contains an electronic or mechanical frequency step switch () o), the several frequency-determining elements (11), e.g. ohmic resistors, switches periodically or aperiodically so that each Therapy frequency one remains switched on for a defined period of time and then the next therapy frequency is switched on in a very short time.

According to the invention, the following details are provided for a meaningful design Suggested: The frequency step switch (10) is used as an automatic time switch it freezes out with an adjustable switching rhythm. The horseshoe matrix (2) can be made flexible by using the ferromagnetic material (4) the coils (7) in a flexible tape or other flat cover - for example Made of rubber or flexible plastic - cast in or inserted, as a ferromagnetic Material (4) and housing (8) are used for this purpose stranded wire or braided wire or so-called. Metglas in question (amorphous flexible ferromagnetic, shock-cooled from the melt Material).

The output stage of the generator (9) is expediently in the Treatment elements horseshoe matrix (2) or club, 1atrix (3) relocated to none Letting losses occur due to lead resistance and inductance are advantages of the invention are optimal efficiency and optimal therapeutic effect as well negligible reduction of the arrangement when used in cosmetics and dermatology, shorter therapy time and thus higher economic efficiency than with arrangements with continuous frequency modulation and optimal adaptation of the treatment element Horseshoe matrix (2) to the patient's body shape.

The subject of the invention is the combination of several Horseshoe or U-shaped ferromagnetic materials (4) in wire, tape or Strand shape to form a horseshoe matrix (2) and its flexible design with each alternating magnetic south poles (5) and north poles (6), with a housing (8) the Feldw lines can only emerge on the treatment side.

The invention also relates to the modification of the horseshoe matrix (2) to a so-called lobe matrix (3) by utilizing the known directivity of several Ferromagnetic materials (4) connected in parallel in wire, tape or stranded form with coils (7) according to FIG. 4.

Finally, the invention relates to the use of an automatic Frequency step switch (1o) in the control of the treatment elements horseshoe matrix (2) and / or club matrix (3) as well as the use of the entire arrangement in cosmetics and dermatology.
