Description

[Detailed description of the invention] Industrial applications The present invention relates to a medical soft magnetic sheet.

BACKGROUND OF THE INVENTION Films made of rubber-like soft plastics in which permanent magnetic particles of ferrite material, such as barium or strontium ferrite, are embedded are already known. These sheets are magnetized with a plurality of magnetic poles of alternating polarity, such that their effective, i.e., surface facing the human body in use, is magnetized with a plurality of magnetic poles of alternating polarity, i.e., straight lines extending in parallel with the same distance between the poles, i.e. The strip is followed by the south pole strip, and so on.

These sheets are intended to be fixed to the corresponding body parts.
The magnetized surface may be provided with a skin-compatible adhesive layer (DE 31 47 852).

However, these magnetic sheets are limited in their optimal use and their therapeutic efficacy.

Blood, for example, behaves like an electrically conductive fluid medium, so that an alternating magnetic field induces in the body part a low voltage or current that acts on the body part to be treated; Local heating and blood circulation promoting effects are produced especially in the peripheral area.

However, the optimal therapeutic effect, which is characterized in particular by the relief and elimination of pain, is only obtained if the magnetic poles of crossed t♀ polarity extend across or at right angles to the direction of blood flow.

In the case of known medical magnetic sheets, the strip-shaped magnetic poles of alternating polarity extend in only one direction, in which case the direction in which the strip-shaped magnetic poles extend is unknown when the sheet is observed. For this reason, known magnetic sheets cannot be eliminated from being improperly removed, resulting in little therapeutic efficacy. Therefore, it is unclear whether the sheet is attached to the body part to be treated in a manner that produces optimal therapeutic effect.

This difficulty is exacerbated by the fact that the therapeutic magnetic sheets can be easily obtained anywhere without a prescription by individual laymen who are unaware of the above relationship.

Another drawback of the known sheet is that due to the plurality of alternatingly polarized magnetic poles extending in one direction, the therapeutic effect is significant only on blood vessels that extend across them.

Problems to be Solved by the Invention The object of the invention is that, while avoiding these drawbacks, it can be applied to the body parts to be treated in any arbitrary position and without special guidance and expertise; The object of the present invention is to create magnetic sheets of the type mentioned above, with which an optimal therapeutic effect can be obtained at all times.

Means for Solving the Problem According to the invention, this problem is solved if the magnetic poles of alternating polarity have a geometrical mulberry-like shape, in which case these magnetic poles are arranged in sheets, concentrically and at an angle. and/or in a radially extending plane.

Embodiment Part 1 In an advantageous embodiment, the magnetic sheet is provided with a plurality of magnetic poles in the form of a plurality of rings arranged concentrically with respect to each other and having alternating polarity from ring to ring.

Also in an advantageous embodiment, the magnetic sheet is arranged with magnetic poles in the form of sectors with alternating polarity from sector to sector.

In another embodiment of the invention, the magnetic seam 1 is
It can be constructed in such a way that it consists of a number of sheet parts provided with a plurality of alternatingly polarized magnetic poles, which sheet parts are preferably connected to one another by a non-magnetic soft adhesive sheet.

It is advantageous for the magnetic poles to have mutually different magnetic poles 1j and/or different pole-to-pole spacings, as described in German patent application No. P 33 25 356.0. In any case, this applies to sectored pole structures.

A metal coating can be provided on at least one side of the sheet to retain or reflect body heat. This coating is
For example, it can be vapor deposited.

To avoid wear and tear on the metallization, it can additionally be provided with a protective layer, for example a lacquer.

Effect: With this solution, it has been achieved that a plurality of alternatingly polarized magnetic poles can act on a plurality of blood vessels, each with an arbitrary blood flow direction. A particular advantage of the invention is therefore that an optimal therapeutic effect is always achieved, regardless of the state of the magnetic sheet on the body part to be treated.

Furthermore, compared to known magnetic sheets, the therapeutic effect is not limited to a single blood flow direction.

Therefore, according to the invention, it is not only possible to use it freely, i.e. independently of position, but also to achieve an optimal therapeutic effect in all directions of blood flow, especially in the peripheral skin area. However, a medical magnetic sheet that can be used for IJ has been created.

It consists of a skin-compatible rubber-like soft plastic in which permanent magnetic particles of moufferite or strontium 7-elite are embedded.

As is clear from FIG. 1, on the effective surface contacting the body part to be treated, the magnetic sheet 1 is provided with a plurality of rings 3 in the form of a plurality of rings 3 arranged concentrically with respect to each other and having alternating polarity from ring to ring. A magnetic pole 2 is provided. In this figure the north and south poles are represented by the symbols N and S. These may have different electrode widths a4+a2.

In a further embodiment according to FIG. 2, the magnetic sheet 1 is magnetized with a plurality of magnetic poles 2 in the form of a plurality of sectors 4 with alternating polarity from sector to sector. Again, the north and south poles are represented by the symbols N and S.

In a further embodiment according to FIG. 6, a plurality of magnetic poles 2 of alternating polarity have the shape of a quadrilateral 5 and are arranged concentrically with respect to each other in the magnetic sheet. It is not necessary that the respective magnetic poles abut or connect to each other at the corners.

According to another embodiment according to FIG. 4, several triangular-shaped soft magnetic sheet members 8 are attached to a non-magnetic soft sheet 7 provided with an adhesive layer. A sector-shaped pattern is thus obtained, in which a plurality of magnetic poles 2 are developed at an angle to each other. Furthermore, the north and south poles are represented by the symbols N and S.

Evidently, a plurality of magnetic poles on the sheet are arranged concentrically, angularly and/or radially with respect to each other,
As long as their alternating magnetic pole dynamics intersect with the vertically as well as horizontally extending blood flow direction, they can also have different geometric patterns. In this case, the shape of the sheet can be arbitrary, for example, disc-shaped, rectangular, or square.

In order to secure the sheet to the skin, one side of the sheet may be provided with a skin-compatible adhesive coating (not shown), which coats a releasable sheet IJ.
Protected by a J-n paper covering. However, the magnetic sheet may also be fixed using a separately applied skin-compatible plaster.

A metal coating 6 is provided on the back side of the sheet to maintain or reflect body heat. This coating can be applied by adhesive or vapor deposition.

In order to avoid wear and tear on the metallization, it can additionally be provided with a protective layer, for example a lacquer.
