Description

[Detailed Description of the Invention] The present invention provides pain relief by applying magnetic lines of force to the human body.
The present invention relates to medical magnets that are useful for eliminating physical discomfort such as numbness and heaviness, or for promoting health.

Prior Art Problem to be Solved by the Invention It is well known that magnetism affects the human body and has the effect of alleviating discomfort such as stiffness and pain and promoting health. bangles, magnetic pine tresses,
Many magnetic treatment instruments such as magnetic band Magrain and magnetic particles with adhesive bands have been commercially available and in use.

On the other hand, magnetic particles with adhesive bands, which have been rapidly used recently, can apply magnetic field lines directly to the affected area, no matter what part of the body it is, but they do not come into contact with the skin. Because the magnetic poles present are limited to one pole (often the north pole), it is not possible to create a strong magnetic field at the affected area, and the lines of magnetic force that act on it are extremely weak.

That is, when using a magnet for magnetic therapy, various treatment methods have been proposed, but conventionally a single magnet with a pair of N and S poles has been used. The simplest method of use is to apply the north pole of the single magnet mentioned above to the skin surface of the affected area and fix it with an adhesive band or the like to perform treatment.

However, as various magnetic therapy methods using magnets have been tried, treatments such as applying the north pole of a single magnet to the affected area and then applying the south pole of another single magnet adjacent to it have also been found to be effective. It is becoming. The present inventors previously filed a patent application in Sho 6l-
21521 (>) found that using a pair of strong magnetic forces with a large contact area that contact the affected area would be very effective in treatment, and proposed a new magnetic therapy device. .

It was discovered that using a magnet with multiple poles on eight sides would be even more effective whether used alone or in combination, and filed a patent application as Japanese Patent Application No. 259970/1983.

As a result of extensive studies, the inventors of the present invention found that the therapeutic effect would be even better if the magnetic pole surface that comes into contact with the human body is shaped like a protrusion, and the protrusions are arranged alternately as N and S poles. The present invention was developed based on this knowledge.

Means for Solving the Problems A new type of medical magnet proposed by the present invention has a surface that comes into contact with the human body having a plurality of protruding magnetic poles.
This medical magnet is constructed so that poles and south poles are arranged alternately.

There are several ways to construct the protruding magnetic poles on the surface that comes into contact with the human body, such as split magnetization of a single-piece molded product, assembling a single magnet, and assembling a unit magnet consisting of multiple poles. It is also convenient to configure the section and the protruding section separately and to combine them.If the protruding section is made of a magnetically permeable material and combined with the magnet section, it is easy to handle and has a remarkable therapeutic effect. In addition, various methods as described below are applicable to the present invention.

The medical magnet of the present invention has N on its contact surface with the human body.

Since it has protruding magnetic poles in which S poles are arranged alternately, it penetrates deeply into the vicinity of affected areas, acupuncture points, etc. where it comes into contact with the human body, and stimulates the human body with the protruding parts, as well as strongly acting on lines of magnetic force. In other words, since the magnet of the present invention has a plurality of protruding magnetic poles, the magnetic flux density near the protrusions is stronger than in the case without protrusions, and at the same time, it is thought that a plurality of magnetic circuits are formed, and the therapeutic effect is higher than that of conventional medical magnets. It's much better.

When carrying out the present invention, there is no particular restriction on the number of protruding magnetic poles on the contact surface as long as it is possible to manufacture them, but a sufficient effect can be obtained if the number of protruding magnetic poles on the contact surface is several to several dozen per 1 to 1 contact area of the magnet. can be expected. In particular, when there are four protruding magnetic poles, it is convenient to manufacture and remove, and if it is a square with four protrusions, it is even more advantageous to use them in combination as a unit magnet without having to consider the direction. It is. In this case, the area of contact with the human body can be set to any size depending on the area of the treatment area. There is no particular restriction on the shape of the abutting surface, and in addition to the square, it may be circular, elliptical, donut-shaped, rectangular, hexagonal, hexagonal, or the like. shape of the protrusion,
There are no particular restrictions on the size, but the appropriate height is 10u+
m or less is suitable, and the shape is also conical, 1 cylindrical,
Each trapezoidal shape can be adopted, such as a truncated cone shaped like a pyramid. In particular, a rounded conical shape with a diameter of 1 to 2 mm and a height of 3 to 7 mm is advantageous for stimulating acupuncture points.

The spacing between the protruding magnetic poles is not particularly limited, and it is generally preferable that the protruding magnetic poles are evenly distributed on the contact surface and set at intervals of 3 to 7 degrees. Also, the distance between the protrusions is about 3 to 7 mm ↓
(It is a good idea to keep the trapezoid shape.Also, in the case of the trapezoid shape, if the spacing becomes narrow, it will look like a slit cut in a plane, but in this case too, the magnetic flux density is stronger than that of a plane, and it is advantageous because it can be easily manufactured.) The number of protrusions and the magnetic poles do not necessarily have to correspond one-to-one, and it may be more convenient for manufacturing to have a plurality of protrusions at each of the N pole or the S pole.

The above-mentioned medical magnet of the present invention has one magnetic pole (
ξAlthough it can be manufactured by dividing magnetization so that the N and S poles are alternately configured to constitute a plurality of magnetic poles,
A magnet having only one pole or a unit of multi-pole magnet, for example, a plurality of magnets having four magnetic poles can be collected and assembled so that the N and S poles are arranged alternately on the contact surface. in this case,
They are bonded and integrated by a commonly known method or a method described in the invention previously filed by the applicant (Japanese Patent Application No. 61-215210). In other words, a method of fixing with an adhesive, a method of fixing stainless steel A method of covering with a thin plate of non-magnetic permeable material such as steel, aluminum and its alloys, copper and copper alloy, a method of coating and fixing plastic, rubber, leather, paper, woven cloth, etc. as a protective member can be advantageously used.

A specific example of plastic is polyethylene.

Polypropylene, vinyl chloride resin, polyester.

Polyamide, acrylic resin, polycarbonate.

Polyurethane, ABS resin, etc., and specific examples of rubber include natural rubber and synthetic rubbers such as butadiene-styrene rubber, butyl rubber, chloroprene rubber, silicone rubber, and the like.

Even when the medical magnet of the present invention is constructed by dividing the single magnet into magnets, it is advantageous to use a protective member in the same manner for ease of handling.

The protective member can be used in a variety of ways. The simplest way to use magnetically non-permeable materials is to coat the entire medical magnet. The coating strengthens the magnet and prevents it from being damaged during handling, and when used for magnetic therapy, it has the effect of softening the contact with the friend during treatment and making treatment operations easier. I can do it. Various coating methods can be used as the coating method. In addition to painting with ordinary liquid paints, when plastic is used as a protective member, it can be advantageously and beautifully painted by a fluidized dipping method using powder.

It is also possible to perform painting using metal plating or composite plating. When coating medical magnets with non-magnetic materials such as metals such as stainless steel, aluminum, aluminum alloys, copper, and copper alloys, plastics, leather, paper, cloth, etc., foil of the material.

It is convenient to use by gluing thin plates etc. together using an adhesive, or by making a suitably shaped casing, bag, etc. and inserting a magnet therein.

In addition, when constructing the magnet of the present invention, a foil made of a magnetically permeable material such as iron, nickel, cobalt, or an alloy thereof, in order to increase the magnetic flux density of the contact surface and to protect and reinforce the magnet.
It is also an effective means to cover an appropriate part of the magnet surface with a plate or the like, for example, to cover the bottom surface.

In both of the above cases, the medical magnet of the present invention is composed of an integrated magnet, but it is not necessarily necessary to integrate the entire magnet with a magnet, and only the protruding portion is composed of a magnet, and the substrate is made of a magnetically permeable material. Alternatively, the protruding portion may be made of a magnetically permeable material and the substrate may be made of a magnet. In the former case, if the protrusions are made of magnets with truncated cone-shaped north or south poles, they can be arranged on the substrate with arbitrary distribution and spacing; Depending on the condition of the affected area, this method may be more effective for treatment. When configured with n - , the magnetic flux density of the protruding portion may be increased by n − and the therapeutic effect may be enhanced compared to when the entire portion is composed of an integrated magnet.Furthermore, the protruding portion does not necessarily need to be composed of a magnetically permeable material. It can also be made of stainless steel, aluminum alloy, or plastic ceramics, etc., so that stimulation of the affected area and the action of magnetic lines of force can be shared.

In this way, for example, it is possible to expand the range of ways in which stimulation can be given to the human body, such as by giving a soft touch, and if the height of this protruding part is made small, the effect of magnetic lines of force from the magnet that serves as the substrate can be increased. does not substantially decrease,
Conversely, various effects such as controlling the strength of magnetic lines of force can be achieved by adjusting the height. For example, if this is applied to the soles of slippers, shoes, etc., the effects of magnetic lines of force will be added to the same effect as the so-called ``green bamboo stomping'', so it can be expected to have the effects of improving health and increasing physical strength. The same effect can be expected for items that are constantly kept in close contact with the human body, such as headbands, bellybands, corsets, etc., by using a similar structure.

In this case, the applicant should first apply the
The "plate magnet" filed on May 19th can be advantageously used as it is as a substrate, or the whole can be molded from a plastic magnet.

Furthermore, when the medical magnet of the present invention is composed of a plurality of unit magnets, various magnetically permeable or non-magnetically permeable materials can be interposed between the magnets, thereby increasing or controlling the magnetic flux density. Various effects may be achieved.

There are no particular restrictions on the type of magnet used in the present invention, and generally widely used commercially available ferrite magnets, alnico magnets, rare earth magnets, and plastic magnets using these magnets can be used. Since the magnet 4 has a strong magnetic force, it has the advantage of being able to be made smaller in size and can be used advantageously.

When using the medical magnet of the present invention, it may be pressed against the affected area by hand, but if the contact surface of the magnet is small, it is recommended to use it by fixing it with an adhesive band, etc., so that it can withstand long-term use. Needless to say, it's convenient.

Hereinafter, embodiments of the present invention will be explained based on the drawings. Figs. 1 and 2 show an example of the medical magnet of the present invention having a disc-shaped contact surface. In this example, the contact surface is made up of four conical protruding magnetic poles with N and S poles arranged alternately, and the top of the cone is rounded to slightly soften the stimulation to the human body. It is shaped like this. In the example of FIG. 1, the abutting portion with the protrusion is made of an integrally molded magnet as shown by ■, but it can of course also be constructed by combining a single pair of N and S pole magnets. In this embodiment, a soft steel plate made of a magnetically permeable material (2) is attached to the bottom of the magnet to increase the magnetic flux density near the protrusion that comes into contact with it.

In the example shown in Fig. 2, the shape of the medical magnet is the same as in the example shown in Fig. 1, and it has four protrusions, but the protrusion v at the part that comes into contact with the human body is
The A pole portion (■) is made of magnetically permeable mild steel. Generally used ferrite magnets and rare earth magnets are sintered magnets, which are brittle and difficult to process. If the disk-shaped sintered magnet part and the protrusion part are constructed separately as shown in Figure 2, it is advantageous because the protrusion abutment part, which is difficult to process, can be made of a magnetically permeable material such as iron or iron alloy that is easy to process. many.

In this case, the substrate (2) is made of rare earth magnet.

In FIG. 3, the protruding magnetic pole (2) of the abutting portion has a square trapezoid shape, and is composed of six protruding magnetic poles in which N and S poles are arranged alternately. In this embodiment, six single magnets each having one north pole or one south pole are combined.

Furthermore, if the number of unit magnets, each consisting of two N and S poles, can be freely disassembled during use, the number can be increased or decreased depending on the condition of the affected area, which is very convenient.

FIG. 4 shows an example in which the protruding magnetic pole (2) of the abutting portion is made of a magnetically permeable material, and the substrate (2) is made of a rare earth magnet, with a plurality of protrusions forming N and S poles.

FIG. 5 shows an example of how the medical magnet shown in FIG. 3 is used, where ■ is a magnet, ■ is a protrusion, ■ is an adhesive tape, and ■ is a human body.

Treatment Example 1 A medical magnet shown in FIG. 2 was used for treatment. The magnet (2) is a 10φ samarium and cobalt rare earth magnet, and the contact protrusion (2) is made of mild steel and has a height of 6 m. 5
Two of the medical magnets of the present invention described above were attached to the affected area using an adhesive band for a 4-year-old male patient who was complaining of straining in his left shoulder. Two hours later, the strain in the patient's left shoulder was significantly reduced.

Also, my skin is sensitive and after applying a commercially available magnet for a day, the marks from the adhesive band became itchy, but this time the treatment time was very short, so I didn't experience any itching from the adhesive band.

Treatment Example 2 A male patient, 57 years old, who was complaining of soreness in the muscles near the knee joint of his left leg during movement, was treated using the medical magnet shown in Figure 3. The contact area was 10×15#, the height of the trapezoidal protrusion was 7#, and a neodymium iron-based rare earth magnet was used as the magnet.

When treatment was applied to the affected area using an adhesive band, almost no pain was felt after 3 hours.

Effects of the Invention Since the medical magnet of the present invention has a plurality of protrusions on the contact surface, it stimulates the affected area, especially acupuncture points, and at the same time, combined with the action of magnetic lines of force, it has a more excellent therapeutic effect than conventional magnetic therapy devices. It can be played. Furthermore, if this product is used in slippers, shoes, belly wraps, etc. that are kept in close contact with the human body, it is expected to have effects such as improving health and increasing physical strength.

In this case, the area of contact with the human body can be set to any size depending on the area of the treatment area. There is no particular restriction on the shape of the abutting surface, and in addition to the square, it may be circular, elliptical, two-ring (doughnut), rectangular, hexagonal, hexagonal, or the like. There are no particular restrictions on the shape or size of the protrusion, but the height is usually 1
The suitable length is 0 m or less, and the shape can be a conical shape, a bicylindrical shape, a pyramid shape, or a trapezoidal shape such as a truncated cone. In particular, a rounded conical shape with a diameter of 1 to 2 seconds and a height of 3 to 7 inches is advantageous for stimulating acupuncture points. The spacing between the protruding magnetic poles is not particularly limited, and it is generally preferable that the protruding magnetic poles are evenly distributed on the contact surface and set at intervals of about 3 to 7 m. Also, the distance between the protrusions is preferably about 3 to 7#. In addition, in the case of the trapezoid shape, when the spacing becomes narrow, it looks like a slit has been cut in a plane, but in this case as well, the magnetic flux density is stronger than that of a plane, and it can be manufactured easily, so it can be said to be advantageous. The number of protrusions and the magnetic poles do not necessarily have to correspond one-to-one, and it may be more convenient for manufacturing to have a plurality of protrusions at each of the N pole or the S pole. As mentioned above, the medical magnet of the present invention can be manufactured by dividing magnetization so that the magnetic poles of one magnet are alternately N and S to form a plurality of magnetic poles, A magnet having only one pole or a unit of multi-pole magnet, for example, a plurality of magnets having four magnetic poles can be collected and assembled so that the N and S poles are arranged alternately on the contact surface. In this case, they are combined and integrated by a commonly known method or a method described in the invention previously filed by the applicant (Japanese Patent Application No. 61-215210). That is, methods of fixing with adhesive, methods of covering with thin plates of non-magnetically permeable materials such as stainless steel, aluminum and its alloys, copper and copper alloys, and methods of using plastic, rubber, leather, paper, woven cloth, etc. as protective members. A method of coating and fixing can be advantageously used. A specific example of plastic is polyethylene. Polypropylene, vinyl chloride resin, polyester. Polyamide, acrylic resin, polycarbonate.

The coating strengthens the magnet and prevents it from being damaged during handling, and when used for magnetic therapy, it can have the effect of softening the contact with the skin during treatment and making treatment operations easier. can. Various coating methods can be used as the coating method.

It is convenient to use by gluing thin plates etc. together using an adhesive, or by making a suitably shaped casing, bag, etc. and inserting a magnet therein. In addition, when constructing the magnet of the present invention, a foil made of a magnetically permeable material such as iron, nickel, cobalt, or an alloy thereof, in order to increase the magnetic flux density of the contact surface and to protect and reinforce the magnet.
It is also an effective means to cover an appropriate portion of the magnet surface with a plate or the like, for example, to cover the bottom surface. It is also possible to construct the entire magnet with a plastic magnet, which is considered to be more economically advantageous, so this is also an effective means depending on the application. In both of the above cases, the medical magnet of the present invention is composed of an integrated magnet, but it is not necessarily necessary to integrate the entire magnet with a magnet, and only the protruding portion is composed of a magnet, and the substrate is made of a magnetically permeable material.

The height does not substantially decrease, and on the contrary, various effects such as controlling the strength of the magnetic lines of force can be achieved by controlling the height. For example, slippers. If this is applied to the soles of shoes, etc., the effects of magnetic lines of force will be added to the effect of so-called ``green bamboo stomping'', so it can be expected to have the effect of improving health and increasing physical strength. This means that items that are constantly attached to the human body, such as headbands,
The above effects can be expected with similar configurations for belly bands, corsets, and the like. For such applications, it is especially advantageous to construct the magnet entirely from the plastic magnet. In the case of such a structure, the "Single Plate Magnet" previously filed by the present applicant on January 19, 1988 can be advantageously used as a substrate, or the whole can be molded with a plastic magnet. It is particularly suitable for uses that require flexibility, such as headbands and bellybands. Furthermore, when the medical magnet of the present invention is composed of a plurality of unit magnets, various magnetically permeable or non-magnetically permeable materials can be interposed between the magnets, thereby increasing or controlling the magnetic flux density. Various effects may be achieved. The type of magnet used in the present invention is not particularly limited, and generally widely used commercially available ferrite magnets, alnico magnets, rare earth magnets, and plastic magnets using these magnets can be used, but rare earth magnets are particularly suitable.

In this example, four conical protruding magnetic poles 1 with N and S poles arranged alternately are arranged on the contact surface, and the top of the cone is rounded to slightly soften the stimulation to the human body. It is shaped like this. In the example of FIG. 1, the abutting portion with the protrusion is made of an integrally molded magnet as shown by 1, but it can of course also be constructed by combining a single pair of N and S pole magnets. In this embodiment, a mild steel plate made of a magnetically permeable material (2) is attached to the bottom of the magnet to increase the magnetic flux density near the protrusion that comes into contact with the magnet. In the example shown in Figure 2, the shape of the medical magnet is the same as the example shown in Figure 1, and it has four protrusions, but the protruding magnetic pole part 1, which is the part that comes into contact with the human body, is made of magnetically permeable mild steel. . Generally used ferrite magnets and rare earth magnets are sintered magnets, which are brittle and difficult to machine. If the disk-shaped sintered magnet part and the protrusion part are constructed separately as shown in Figure 2, it is advantageous because the protrusion abutment part, which is difficult to process, can be made of a magnetically permeable material such as iron or iron alloy that is easy to process. many. In this case, the substrate 2 is made of rare earth magnets. In FIG. 3, the protruding magnetic pole 1 of the abutting portion has a square trapezoid shape, and is composed of six protruding magnetic poles in which N and S poles are arranged alternately. In this embodiment, six single magnets each having one north pole or one south pole are combined. Further, if the unit magnets each having a pair of N and S poles can be freely disassembled and assembled during use, the number can be increased or decreased depending on the condition of the affected area, which is very convenient. FIG. 4 shows an example in which the protruding magnetic pole 1 of the abutting portion is made of a magnetically permeable material and the substrate 2 is made of a rare earth magnet, with a plurality of protrusions forming N and S poles. FIG. 5 shows an example of how the medical magnet shown in FIG. 3 is used, in which 1 is a magnet, 2 is a protrusion, 3 is an adhesive tape, and 4 is a human body. Figure 6 shows a combination of magnets with square trapezoidal protrusions of different heights to match the unevenness of the soles of the feet! - An example is shown in which the N, S and poles are arranged alternately and used on a human body. -1 is a magnet with projections, and 2 is a human body. Treatment Example 1 A medical magnet shown in FIG. 2 was used for treatment. The magnet 2 is a 10φ samarium and cobalt rare earth magnet, and the abutting protrusion 1 is made of soft FIA and has a height of 6 m. Two medical magnets of the present invention described above were attached to the affected area using an adhesive band for a 54-year-old male patient who was complaining of straining in his left shoulder. The strain on the left shoulder of the resident for 2 hours was significantly reduced. Also, my skin is sensitive and after applying a commercially available magnet for a day, the marks from the adhesive band became itchy, but this time the treatment time was very short, so I didn't experience any itching from the adhesive band. Treatment Example 2 A male patient, 57 years old, who was complaining of soreness in the muscles near the knee joint of his left leg during movement, was treated using the medical magnet shown in Figure 3. The contact area was 1Q x 15#, the height of the trapezoidal protrusion was 7#, and a neodymium iron-based rare earth magnet was used as the magnet. When treatment was applied to the affected area using an adhesive band, almost no pain was felt after 3 hours. Effects of the Invention Since the medical magnet of the present invention has a plurality of protrusions on the contact surface, it stimulates the affected area, especially acupuncture points, and at the same time, combined with the action of magnetic lines of force, it has a more excellent therapeutic effect than conventional magnetic therapy devices. It can be played. Furthermore, if this product is used in slippers, shoes, belly wraps, etc. that are constantly in close contact with the human body, it is expected to have effects such as improving health and increasing physical strength. 4.
