Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a health device that applies magnetic health methods, and in particular, it relates to a health device that applies a magnetic health method, and in particular, uses the change in the position of magnetic lines of force brought about by a flowing magnetic field to spread the device over a wider range. This invention relates to a health device that applies a flowing magnetic field and that sends magnetic force into the body.

(Conventional technology) The human body, which is in contact with the large magnet called the earth, is also a magnetic material and has a magnetic field, but when the magnetic field weakens, the oxygen concentration in the blood decreases and the metabolic process becomes smoother. It is no longer practiced and becomes the cause of various diseases. To deal with this, conventional magnetic health methods have been used to replenish magnetic fields from the outside into the body and generate ions to convert some of the blood's kinetic energy into electrical energy, thereby increasing physical activity. , health promotion or treatment is being carried out. For example, health tools such as the magnetic treatment belt disclosed in Japanese Patent Publication No. 36-7248, health blankets with multiple small magnets fixed to them, health magnetic hats, and magnetic artificial turf health devices have been devised. Along with this, therapies such as micromagnetic metallic particle therapy, alternating magnetic field therapy, patch magnetic field therapy, etc. have been announced one after another (see Teruo Onishi, Amazingly Effective Electromagnetic Therapy, Marunouchi Publishing, 1985).

In addition, as a health device that uses fluids, shoe insoles are known in which water is sealed in a plastic film, and the pressure of the water promotes blood circulation and at the same time relieves the shock between the hard road surface and the shoe. It has been commercialized for this purpose (see Yasuhiko Igarashi, A Health Method for the Back of the Foot Reflective Band, Ikeda Shoten, 1984).

On the other hand, as a material made of a flowing magnetic field, there is a magnetic fluid researched in 1965 by S. It is obtained by colloidal dispersion in a solvent and is applied to sealing, liquid ratio control, magneto-thermal cycles, sensors, displays, etc. (Hiroyuki Ito Industrial Materials Vol. 29 No. 9 85-10
(See page 6, 1981).

For medical purposes, medicines are mixed with a magnetic fluid based on a solvent that has no effect on living organisms, injected into the blood vessels or subcutaneously of a patient in need of treatment, and guided by a magnet from outside the body to concentrate at the affected area. Only methods are being considered.

(Problem to be solved by the invention) Although the treatments of the conventionally known magnetic health devices as described above have changed in various ways, they apply a fixed magnetic field, so they cannot absorb all the magnetic lines of force passing through the human body. The route is uniquely determined. On the other hand, the purpose of simply applying a fluid is to physically prevent a large amount of local gravity from being applied.

Therefore, these are not intended to apply magnetic health methods over a wider area, but to apply health methods only to specific areas, so they are effective health tools that can spread the effects over a wide range of areas. It couldn't be.

The present invention has been made in view of the above-mentioned conventional problems, and aims to provide a health tool that applies a flowing magnetic field that widely spreads the effects of magnetic lines of force.

[Structure of the Invention (Summary of the Invention) To achieve the above object, the present invention uses a thermoplastic polymer to form a health tool having a hollow part inside, and the hollow part is filled with a magnetic fluid. Furthermore, the health tool is characterized in that it is provided with a magnetic field generating means for generating a fixed magnetic field.

First, the thermoplastic polymer used in the present invention is a resin or an elastomer, such as a homopolymer or mutual copolymer of α-olefins such as ethylene, propylene, butene, methylpentene, and hexene; polystyrene, ABS, etc. Styrenic polymers such as resin, As resin, SBR, styrene-butadiene block copolymer; Halogen-containing polymers such as vinyl chloride resin, vinylidene chloride resin, and fluororesin; Vinyl alcohol polymers such as ethylene-vinyl alcohol Acrylic polymers such as methacrylic resin, acrylonitrile resin, and acrylic rubber; Vinyl ester polymers such as polyvinyl acetal and polyvinyl butyral; Polyamide; Polyurethane; Polycarbonate; Thermoplastic polyester; Polyether; Butadiene rubber; Isoprene rubber, neoprene rubber, etc. diene rubber, natural rubber, etc., and these thermoplastic polymers can be used alone or in combination to form a multilayer and used on both sides to produce a hollow molded product, or a single layer or A hollow molded product is manufactured by attaching the multilayer molded product on one side to a material such as metal, wood, ceramics, or a separately molded thermoplastic polymer molded product.

Next, the magnetic fluid sealed in the hollow part is, for example, magnetite, manganese ferrite, nickel ferrite,
A ferromagnetic material such as cobalt ferrite, manganese zinc ferrite, nickel zinc ferrite, barium ferrite, etc. has an average grain size of 300A or less, preferably 200A or less,
Its surface is coated with oleic acid, linoleic acid, undecylenic acid,
Coated with long-chain unsaturated fatty acids such as ricinoleic acid, alkyl sulfates, alkyl allyl sulfates, alkyl ether sulfates, alkylbenzene sulfonates, α-olefin sulfonates, alkyl phosphates, alkyl allyl phosphates Acid ester salts, alkyl glycerin borate ester salts, anionic surfactants such as saturated or unsaturated fatty acids and/or polyoxyalkylene glycols; monoalkyl ethers, polyoxyalkylene glycols = monoalkylphenyl ethers, polyoxyalkylene glycol fatty acids ester, sorbitan fatty acid ester, polyoxydialkylene dirubitan fatty acid ester, N.

Kerosene,
Nonpolar solvents such as peptane, decane, and dodecane, mineral oils such as machine oil and spindle oil, dioctyl adipate,
It is produced by stably dispersing it in an ester solvent such as dioctyl sebacate or in water.

Further, in order to magnetize the above-mentioned magnetic fluid, examples of the magnetized material as a magnetic field generating means disposed near the magnetic fluid include ferrite, KS steel, MK steel, alnico,
OP electromagnets Permanent magnets made of which materials are first mentioned, either used as is or dispersed in a thermoplastic polymer to form a plastic magnet. do. Another example is an electromagnet that has a coil wound around a soft iron core, and is used by passing an electric current through the coil.

The health tool according to the present invention is manufactured as follows.

(1) Extrusion molding, blow molding, using the above-mentioned thermoplastic polymer alone or in combination of two or more.
After creating a single-layer or multi-layer hollow molded product using a method such as molding, a magnetic fluid made of a solvent that does not dissolve the material of the molded product is injected into the hollow part, and the material is heat-sealed or bonded using an adhesive. (2) Molding with a depression in the center by extrusion molding, mold molding, etc. using one or more of the above thermoplastic polymers After creating the object, a magnetic fluid made of a solvent system that does not dissolve the material of the molded object is injected into the recessed part, and then a flat plate made of a material such as metal, wood, ceramics, or a separately molded thermoplastic polymer molded object is injected. (3) A thermoplastic polymer molded product with a depression and an injection port in the center created in the same manner as in (2) and a material such as metal, wood, ceramics, or a separately molded thermoplastic polymer molded product. After joining the flat plate made of (1), (2) and (3).
) is produced by adhering a magnetized material that generates the above-mentioned fixed magnetic field inside and/or outside the hollow part.

At that time, if desired, chemicals such as ultraviolet absorbers, colorants, antistatic agents, and mold release agents may be added to the thermoplastic polymer side during molding, or waterproof paints, colored paints, etc. may be applied to the flat plate material side. There is absolutely no problem with applying it. The magnetization of the magnetic fluid enclosed in the health tool of the present invention as an essential component of the present invention is preferably 10 Gauss or more, preferably 50 Gauss or more, and the viscosity is, for example, at 25°C. 100 OCPS or less, preferably 500
It is desirable that it is below CPS. If the magnetization is less than 10 Gauss, the magnetic replenishment ability into the human body will be extremely weakened, and if the viscosity (25°C) exceeds 100 OCPS, the activity as a flowing magnetic field may decrease significantly. This results in a reduction in the effectiveness of the present invention as a health device applying a flowing magnetic field.

(Function) As is well known, in conventional magnetic health devices that use a fixed magnetic field (for example, fixed type, pasted type, etc.), lines of magnetic force are emitted from the N pole to the S pole in the magnetic material that is fixed in position on the human body. However, in the health device that applies a flowing magnetic field of the present invention, the magnetic field dispersed in the liquid is first applied from the health device side. In addition to the fact that there are instantaneous changes in the individual magnetic fields due to the Brownian motion of body particles, the structure of the health device itself is changed so that muscle movements of the human body are transmitted to the health device of the present invention through the thermoplastic polymer molded product. The magnetic field applied to the human body's muscle tissue is in a constantly changing state, making it an overwhelmingly effective stimulator for the human body as a magnetic health method in a microscopic state. There is.

Therefore, if the conventional magnetic health method is a static magnetic health method, the magnetic health method using the flowing magnetic field of the present invention can be said to be a dynamic magnetic health method.

[Panel test example 1] 6 randomly selected men and women between the ages of 25 and 50 whose average train commuting time (one way) is 1 to 1.5 hours.
0 subjects (30 males and 30 females) were divided into three groups and were placed on the fluid magnetic field application health device of the present invention manufactured in Example 1 and comparative test articles 1 and 2 for 20 minutes every day after returning home. Participants were asked to perform a foot arch stimulation test in which they put their weight on for one month, and were asked to answer questions about their progress in recovering from commuting fatigue.

The results of the investigation are shown in Table 1, and it was confirmed that the arch stimulator-type fluid magnetic field applied health device of the present invention has a significantly superior effect on human body fatigue recovery compared to comparative test products 1 and 2. .

This is because when the tester irregularly applies his or her own weight to the health device of the present invention, the activity of the flowing magnetic field is further increased, thereby making the magnetic health method sufficiently effective even when used for a short time a day. This is considered to suggest that this may be the case.

[Panel test example 2: The average working distance is 20-25 km/day18
Thirty people out of 40 randomly selected women between the ages of 50 and 50 were divided into three groups: - days, full working hours (8 hours of restraint), and books manufactured in Example 2. The foot fatigue preventer type fluid magnetic field applied health device of the invention and comparative test article 3.4 were used as shoe insoles, and the remaining 10
We asked human subjects to answer questions about their ability to prevent leg fatigue while using the product and their ability to recover from full-body fatigue the next day after going to bed, while comparing it to when they did nothing.

The results of the investigation are shown in Table 2. By using the health device of the present invention as an insole for shoes during working hours, the stimulation to the human body caused by the flowing magnetic field increases in response to the tester's own walking movements. It was confirmed that it has a remarkable effect on preventing leg fatigue and recovering from whole body fatigue.

[3 panel test examples] 60 randomly selected men and women (30 men and women) between the ages of 18 and 20 who spend an average of 12 hours a day studying (6 hours of class and 6 hours of self-study) The subjects (30 people) were divided into three groups and placed their heads on the fluid magnetic field applied health device of the present invention and comparative test articles 5 and 6 manufactured in Example 3 for 30 minutes every day after finishing studying and before going to bed. The participants completed a test in which they maintained a resting state for one month, and were asked to answer questions about their ability to recover from head fatigue.

The results of the investigation are shown in Table 3, and the health tool of the present invention has significantly better recovery from head fatigue than Comparative Test Products 5 and 6, and the flowing magnetic field constantly stimulates the entire back of the head while resting. It was found that this has the effect of promoting this from the outside.

Additionally, 3 out of 20 test subjects for the health device of the present invention had been experiencing habitual headaches on a daily basis, but after conducting this panel test, the treatment effect was observed in that the symptoms almost disappeared. Ta.

[Panel test example 4] Thirty out of 40 randomly selected men between the ages of 25 and 50, whose average driving time is 10 hours/day, were divided into three groups, and each day after leaving home, The remaining 10 participants were asked to continue a test in which they wore the lower back fatigue prevention device type fluid magnetic field application health device of the present invention manufactured in Example 4 and Comparative Product 7-28 until they returned home after commuting. The subjects were asked to compare their ability to prevent lower back fatigue while using the product and to recover from full-body fatigue the next day after sleeping.

The investigation results are shown in Table 4, and since the health tool of the present invention acts widely on the lumbar region, which is the key point of the human body, while constantly changing the magnetic field, it has both lower back fatigue prevention properties and whole body fatigue recovery properties compared to comparative test product 7. It was confirmed that it was much better than 8.

In addition, 4 out of 10 test subjects for the health device of the present invention had mild symptoms of chronic lower back pain, but after conducting this panel test, they continued to use the health device of the present invention without taking it off even when sleeping for 6 months. We also received responses regarding the therapeutic effect, such as the fact that when people wore the product, they experienced almost no lower back pain symptoms.
