Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an application of a rubber sheet carrying far-infrared radiating tourmaline powder, which is effective for maintaining and treating physical health.

[0002]

2. Description of the Related Art Far-infrared radiation is effective for relieving and treating muscle pain and / or joint pain, and far-infrared radiation therapy equipment has been put into practical use as a medical device. However, many patients with myalgia and / or arthralgia are aware of pain relief during the far-infrared irradiation time of the far-infrared radiation therapy device, but do not recover pain after leaving the therapy device. It is said that there are many cases where they are not aware that they are completely cured.

As described above, since many patients with myalgia and / or joint pain are aware of pain relief when irradiating the affected area with far infrared rays, continuous irradiation with far infrared rays is performed. A health treatment tactile article has been proposed that makes it possible. The proposal is to fabricate a health treatment tactile article by mixing a cloth to be worn, such as underwear, with a powder of pyroelectric ceramics or tourmaline in a binder, and pattern-coating the radiation effect of far infrared rays, It is expected that the effect of electrical stimulation given to the body by the action of pyroelectric and piezoelectricity of pyroelectric ceramics will be for the prevention or treatment of low back pain, neuralgia and stiff shoulder. (For example, see Japanese Patent Publication No. 1-198566)

However, it is considered that there is a problem in the relationship between the amount of the functional component effectively acting on the coating surface and the therapeutic effect in the above-mentioned conventional health care tactile article. That is, the conventional coating method for fixing the necessary weight of pyroelectric ceramics or tourmaline per unit area on the surface of the function of the tactile material for health treatment leaves an unsolved technical problem in its practical application. It is believed that

Further, the surface of the health-care tactile article produced by coating the above conventional pyroelectric ceramic or tourmaline in a binder and coating the same leaves medical problems such as skin irritation or contact poisoning of the binder. It is thought that
In addition, the problem of discomfort due to various causes on the mounting surface when mounting on the affected area is considered to be an unsolved problem.

[0006]

In the conventional health care tactile article, an effective amount of pyroelectric ceramic per unit area of the surface that functions in contact with an affected area for the purpose of preventing and / or treating pain is provided. As mentioned above, there was a problem in terms of technical and economic costs for fixing.

The present invention focuses on the fact that tourmaline is a far-infrared radiator expected to have an effective therapeutic effect on local diseases that cause muscle pain and joint pain at room temperature. As a result, we have proposed a health-care tactile object with tourmaline powder fixed.

It can be said that the therapeutic effect of a health care tactile article using a far-infrared radiator as a functional material depends on the amount of far-infrared energy received by an affected part in the range of room temperature or near body temperature. It is considered that the weight of the far-infrared radiator per unit area of the body correlates with the therapeutic effect. In general, the therapeutic effect of the tactile object for health treatment is sensual, and it is necessary to rely on the patient's subjective judgment or expression. We have proposed a health treatment tactile article that can be expected to have an effective effect by quantifying the weight relationship of the far infrared radiator.

Further, the present invention is a lightweight body which enables a wearer of a health care tactile article to wear it for a long time in a cycle of life without feeling any discomfort in various kinds of work and exercise. , And a health treatment tactile article that is highly flexible is proposed.

[0010]

In order to solve the above-mentioned problems, in the present invention, a rubber sheet obtained by kneading a powder of tourmaline which radiates far infrared rays at room temperature is used for a functional portion of a health care tactile article. It is what

The reason why rubber is used as a carrier for powder of tourmaline in the present invention is (1) rubber is compounded at a relatively high concentration when kneading an insoluble inorganic additive such as tourmaline powder. Even when the tourmaline powder is fixed at a high concentration, it can be molded into an elastic body having physical properties required for a health care tactile article such as hardness, elasticity and elasticity.

(2) Health treatment It is desirable to reduce the weight in order to reduce the burden of wearing tactile materials, but rubber is made lighter by blending wood powder, glass balloons, shirasu balloons, etc. as a weight reducing material. Can be expected. Further, it is possible to reduce the weight by using a foam molding method.

(2) Health treatment When a tactile article is attached to the affected area, the rubber has elasticity and elasticity, so that it can be expanded and contracted in accordance with the operation of the affected area so as not to hinder the operation of the affected area. It is a material that can reduce the discomfort caused by the operation of the parts.

(3) Rubber is a material that can be easily laminated with cloth, nonwoven cloth, or the like. When using rubber as a tactile object, by laminating the surface of the rubber with a cloth or a non-woven fabric, the surface of the tactile object can be made of a material similar to clothing, reducing the discomfort caused by the contact between the rubber and the skin. can do. In addition, it is possible to enhance the sewing workability of the tactile material and expand the range of use.

(4) Rubber can be easily selected from materials that are considered to have relatively high biomedical safety, such as silicone rubber, which is unlikely to cause allergies when it comes into contact with the skin.

Among the rubbers used as carriers for tourmaline powder, silicone rubbers are known as tactile substances for medical treatment, which are said to have high biomedical safety, as mentioned above. The types of rubber that are considered to have relatively high biomedical safety are as follows. However, it is limited to the range of great grades such as medical supplies, food products, and clothing. or,
It should be additionally noted that what remains as an unreacted component after vulcanization may be toxic.

Silicone rubber Natural rubber Synthetic natural rubber Chloroprene Butyl rubber Nitrile rubber Ethylene propylene rubber Urethane rubber

The rubber sheet used for health treatment tactile is
The present invention proposes to use a rubber sheet with holes if necessary because it has almost no permeability to moisture such as sweat. The porosity is 15 to 30%, and the shape of the holes is preferably circular, quadrangular, star-shaped, or cross-shaped depending on the application. Further, by using a rubber sheet having holes, it is expected to reduce the apparent specific gravity of the tactile material for health treatment.

The wall thickness of the rubber sheet used for the health care tactile article of the present invention is in the range of 0.5 to 2 mm to satisfy the function and cost. The thickness of the rubber sheet should be determined in consideration of the amount of tourmaline powder added.

In the health care tactile article proposed by the present invention, the amount of tourmaline powder added to the rubber is in the range of 0.01 to 0.05 g per 1 cm 2 of the surface area of the rubber sheet. In the range of the amount of the tourmaline powder added, most patients who wear the health care tactile article experience an effective therapeutic effect. Further, it is considered that there is no particular technical problem from the kneading process of the rubber compound to the molding process within the above-mentioned addition amount range, and the rubber sheet can be molded within the economical cost range.

When the above-mentioned rubber sheet is directly attached to the skin of the affected area as a tactile object, there are many cases in which the affected area of the skin feels a feeling of coldness or a strange feeling. or,
It has been found that the high surface friction resistance peculiar to rubber gives a different sense of discomfort. Furthermore, the specific gravity of the rubber sheet mixed with tourmaline is around 1.2, and the magnitude of this specific gravity may cause discomfort.

As means for alleviating the above-mentioned drawbacks of the rubber sheet as a tactile article, the present invention provides one side of the rubber sheet,
Alternatively, it is proposed to avoid direct rubber contact with the film by laminating a cloth or a non-woven fabric on both surfaces. By laminating a cloth or a non-woven fabric on the rubber sheet, the holes of the rubber sheet are covered with the cloth or the non-woven fabric so that the holes cannot be seen in appearance. However, it may be considered that the water permeability function of the pores is maintained or enhanced.

As described above, the rubber sheet prepared by kneading the tourmaline powder has a specific gravity of about 1.2. However, a health care tactile article having a reduced specific gravity while maintaining the therapeutic effect is expected. . The present invention, in combination with the powder of tourmaline,
It has been proposed to blend wood powder, shirasu balloon, or glass balloon as a weight-reducing material and use a rubber sheet having a specific gravity of about 0.7 as a health care tactile article.

The rubber sheet, which is a functional part of the health care tactile article of the present invention, is laminated with a cloth or a non-woven fabric, for example, for the purpose of fixing to a shoulder pad, a supporter, a belt or the like, or wearing. It facilitates sewing work.

Tourmaline is composed of crystals that generate piezoelectricity and pyroelectricity, and the energy of the piezoelectricity and pyroelectricity is said to be converted into far infrared rays. Due to the fact that the health treatment tactile article of the present invention is attached to the affected area, forces such as strain, pressure, and friction force act on the rubber sheet, but this also applies to tourmaline fixed to the rubber sheet. The action is transmitted, and the tourmaline produces piezo electricity. It is said that this piezoelectricity is further converted into thermal energy to generate pyroelectricity. Many effective examples prove that far-infrared rays converted from piezoelectricity and pyroelectricity improve blood circulation in an affected area and effectively act on pain relief and treatment.

In the present invention, tourmaline used as a functional material for radiating far infrared rays is shawl, which is also known as iron tourmaline, drabite, which is also known as magma tourmaline, and elbite, which is also known as Lithia Electric
Among the types, it is recommended to use a shawl that has high activity as the above-mentioned functional material and is available at an economical cost.

As described in detail above, it is recommended that the health care tactile article provided by the present invention be formed into a sheet using rubber as the material for fixing the powder of tourmaline as the far infrared radiator. There is. This rubber sheet has elasticity and elasticity, and provides a health-care tactile article that easily fits to the shape of the affected part when attached to the affected part, and that inhibits the motor function of the affected part to a minimum. There is. In addition, the present invention points out a means for alleviating various factors causing discomfort, discomfort, weight, etc. when wearing the health treatment tactile article. The present invention provides muscle pain, joint pain, and neuralgia. The present invention provides a health-care tactile article that can alleviate such pains and expect a more effective therapeutic effect.
