Description

[Detailed Description of the Invention] The present invention relates to a magnetic therapy device that performs magnetic therapy by bringing a magnet into contact with the skin surface and allowing magnetic lines of force to penetrate into the body.

Conventionally, ferrite magnets have been generally used as magnets for such magnetic therapy devices.

However, in order to improve the therapeutic effect, a magnet that can generate stronger lines of magnetic force is desired, and it has been impossible to obtain strong magnetic force with ferrite magnets due to the material they are made of.

For this reason, rare earth magnets have recently been proposed that can provide strong magnetic force, but rare earth magnets are difficult to polish, so the edges of the magnets are rounded, causing pain when they come into contact with the coating surface. There is also a risk of skin damage.

For this reason, some devices have been entirely coated with a resin film or the like, but these have disadvantages such as the magnetic force being reduced by the film and the material cost being high.

The present invention addresses the above-mentioned difficulties, and its purpose is to attach a relatively small rare earth magnet to a ferrite magnet with gentle edges, thereby generating strong lines of magnetic force without damaging the skin surface. can be caused, and
The present invention aims to provide a magnetic therapy device that can reduce material costs.

In this invention, a rare earth magnet, which is stronger than a ferrite magnet, is fitted into a recess formed on one side of a disc-shaped ferrite magnet.
Preferably, the surfaces of both magnets are the same, and the other side of the ferrite magnet is attached to an adhesive base material for application to the skin. When the adhesive base material is applied to the skin surface, the rare earth magnet will be attached to the skin surface. Correspondingly, lines of magnetic force can be obtained from both ferrite magnets and rare earth magnets, but strong lines of magnetic force are generated from rare earth magnets.

EMBODIMENT OF THE INVENTION Hereinafter, the magnetic therapy device of this invention will be specifically explained with reference to the drawings shown as examples.

Reference numeral 1 denotes a disk-shaped ferrite magnet, which is formed by compressing and sintering ferrite powder, and is magnetized to about 700 to 800 Gauss.

A recess 2 is formed on one surface of the ferrite magnet 1, and a rare earth magnet 3 is fitted into the recess 2.

This rare earth magnet 3 is formed by compressing and sintering samarium powder and cobalt powder, and can be strongly magnetized.
In this example, magnetization is performed at 1800 to 2000 Gauss.

The other surface of the ferrite magnet 1 with the rare earth magnet 3 fitted onto the negative surface is attached to the center of an adhesive base material 4 such as a bandage.

Therefore, as shown in FIG. 3, the human body 5 is
7 generated by the ferrite magnet 1 when attached to the affected area.
Magnetic lines of force of approximately 00 to 800 Gauss and strong magnetic lines of force of 1800 to 2000 Gauss generated by the rare earth magnet 3 penetrate into the affected area from the skin surface, resulting in excellent therapeutic effects.

In addition, as the material of the rare earth magnet, in addition to the above examples,
Powders of aluminum, nickel, cobalt, iron, copper, etc. can also be used.

As is clear from the above explanation, the magnetic therapy device of the present invention has a rare earth magnet that has a stronger magnetic force than the ferrite magnet fitted into the recess formed in the ferrite magnet, so strong lines of magnetic force can be obtained. Therefore, it is possible to improve the magnetic treatment effect.

Furthermore, if the surfaces of the rare earth magnet and the ferrite magnet are made the same, there is no risk of causing pain or rash when they come into contact with the skin.

Furthermore, since the rare earth magnet is fitted into a portion of the ferrite magnet, the volume is extremely small, and the material cost can be reduced.
