Description

[Detailed Description of the Invention] The present invention is a strong magnetic bandage characterized by having a magnetic circuit formed by a yoke and a magnet in a shape that can mechanically stimulate the human body. The structure promotes blood circulation and eliminates stiffness in the affected area.

Figures 1 and 2 show a conventionally known ferromagnetic bandage. Figure 1 shows an adhesive sheet 2 attached to a disc-shaped ferrite 1 magnetized in the axial direction.
By attaching the ferrite to the body surface, the ferrite is brought into contact with the body surface, but since only the single magnetic pole of the ferrite is in contact with the body, the magnetic field 4 is completely ineffective on the upper surface, and the lower surface is also inefficient and does not have enough magnetic force to act on the body. In addition, the ferrite surface 5 has drawbacks such as the fact that the adhesive tape does not stick firmly to it. Also,
As shown in FIG. 2, there is a conventional product that provides stimulation by forming projections 6 on the ferrite surface in contact with the body 3, but it has drawbacks such as high cost due to high-pressure molding of the specially shaped ferrite including the projections.

3 and 4 also show a conventionally known example, in which a disc-shaped ferrite etc. 1 is magnetized in its axial direction, and a silicon steel plate with low magnetic resistance, a cast steel plate is placed on the outside of the ferrite 1 so as to surround it. A flexible adhesive sheet 2 made of skin-colored vinyl or the like is bonded to this yoke using a pressure-sensitive adhesive layer 8, and a magnetic circuit is formed by the combination of the ferrite magnet 1 and the yoke 7. A strong magnetic field 9 is generated, and when it is fixed on three sides of the body with the adhesive sheet 2, this strong magnetic field 9 acts strongly on the blood flow in blood vessels, muscles, and mind, relieving stiff shoulders and promoting blood circulation. There is.

In the embodiment of the present invention, as shown in FIG. 5, a circular plate 11 with jagged edges 10 is punched out to form a yoke, and this is pressed into a disc shape as shown in FIG. As shown in Figures 6 and 7, the teeth 10 of the yoke 7 are made to protrude slightly beyond the surface of the ferrite 1, and the area of mechanical stimulation to the body is expanded by the teeth 10 of the yoke 7, where the magnetic circuit formed by the yoke 7 and the magnet 1 is concentrated. This is an embodiment of the present invention in which the effects of the strong magnetic field are greatly enhanced by the action of the strong magnetic field on the body. The ferrite has a normal cylindrical shape, and a tooth-shaped protrusion for stimulation can be formed in any desired shape by the yoke edge.

FIG. 8 is a bottom view thereof.

The present invention is not only extremely effective, but also compact as a whole, as it has a combination of a magnetic circuit made up of a ferrite magnet and a yoke, and a shape that mechanically stimulates the human body, making the magnetic force that acts on the body much stronger than conventional products. You can use it on stock at your convenience.

In addition, the metal yoke surrounds and protects the fragile ferrite, so the ferrite will not break even if you accidentally drop or step on it.

Furthermore, as is well known, the adhesive sheet is not directly attached to the rough ferrite but is attached to the smooth surface of the yoke, so that it can be adhered reliably.

Furthermore, since the yoke can be colored to improve the appearance of the product, the product value can be increased because it can be colored in a more colorful manner than the plain brown color of known ferrite.

In addition to the above embodiments, the present invention may be attached to the back of a futon sheet or pillow cover, and a magnetic field or mechanical stimulation may be applied to the body or head resting on it through the sheet or cover. Various modifications of magnets, yokes and adhesive sheets such as ferrite,
All patterns, coloring, etc. are included in the present invention.
