Description

  The present invention relates to a health care device that provides a human body penetration effect of infrared rays and charged particles.

  When infrared rays are emitted to the human body, it is recognized that there are blood circulation promoting effects, nerve fiber activation effects, analgesic effects, and the like. 2. Description of the Related Art Conventionally, a health care device that is worn on a part of a body and promotes health promotion effect by infrared radiation is known in which Ge and tourmaline are processed into chips as an infrared radiation material.

  In addition, muscle fatigue recovery effect and analgesic effect by penetration of charged particles activated by body temperature of piezoelectric pyroelectric materials such as tourmaline into the human body have been recognized and utilized.

Recently, a composite magnet composed of a magnet material and an infrared radiation material having a piezoelectric pyroelectric effect has been proposed with the aim of a synergistic effect of magnetic field lines, infrared rays and charged particles (for example, Patent Document 1).
JP 05-347206 A

  However, the proposed medical pyroelectric material, such as tourmaline and semiconductor material Ge, is activated while the heating effect due to the human body temperature continues, and emits infrared material specific to it. Although the effect is sustained, charged particles generated by the piezoelectric pyroelectric effect are distorted when the tourmaline is heated by the body temperature and the crystal body is distorted, or the temperature difference between the body temperature and the health care device continues to change. When the entire temperature reaches a steady state after the medical device is mounted, the piezoelectric pyroelectric material electrically belongs to an insulator, so that the amount of emitted charge is drastically reduced and the effect of charged particles is You can't expect. That is, the charge release effect of the piezoelectric pyroelectric material is limited to the time until the temperature of the health care device reaches a steady state, and the action effect is limited in terms of time.

  In addition, tourmaline emits infrared rays having a large thermal effect with a wavelength of 4-10 μm emitted from an energy level of 0.1-0.4 eV, but since it is an insulator, the level density is low, and the excited carrier Since the number is small, a sufficient amount of infrared radiation cannot be ensured by thermal excitation at about body temperature. In addition, since piezoelectric pyroelectric materials such as tourmaline are electrically insulating materials, the number of excited charged particles is small, and the generated charged particles are accelerated by an electric field and have little mobility to move in the object. The charged particle penetration effect cannot be expected so much.

  Furthermore, Ge has a forbidden band width as small as about 0.6 eV, and infrared rays radiated from an impurity level of 0.01 eV are mainly used at a wavelength of about 100 μm and penetrate deeply into the human body. As shown in Wien's displacement law, infrared rays with a wavelength of 100 μm are close to infrared rays emitted from a cryogenic object with a temperature of about 30 ° K. Since the thermal effect is small, the effect is mainly due to heating excitation by body temperature. It seems to be a charged particle penetration effect.

In composite magnets made by press-molding a mixture of magnet powder and infrared radiation material powder produced for the purpose of synergistic effect of charged particles and infrared rays and magnetic field lines, the effect of charged particles is particularly increased. In addition, a manufacturing method in which tourmaline powder, which is a charged particle emitting material, is insulation-coated with a coupling agent in advance and resin-molded has been proposed (Patent Document 2).
JP 2001-126908 A

  The rare earth magnet is a conductive metal material and reflects infrared rays almost completely. The ferrite magnet is an insulator and transmits infrared rays. Therefore, it seems that there is not much absorption loss of infrared rays due to the magnet material, but since the bond resin has a large infrared absorption ability due to the functional group attached to the basic polymer main chain, the infrared radiation material inside the magnet is active at body temperature. Infrared rays that are converted into light are absorbed on the way and hardly reach the surface of the composite magnet. Therefore, the blended infrared radiation material has low effectiveness unless its radioactivity is large.

  As for the effect of charged particles on the human body, the generated charge is limited to the time required to reach a steady state. When the surface of tourmaline, a piezoelectric pyroelectric material, is insulated, the charged particles are insulated. The effect is hardly expected because it is difficult to pass through the membrane. The charged particles that have passed through the insulating film are not trapped in the resin because the lifetime and mobility of the charge in the bond resin are not large, and even if charge is generated from tourmaline, the amount reaching the human body surface is small. Since Ge is a semiconductor, charged particle radioactivity is large, but since the infrared wavelength resulting from the semiconductor band structure is as large as 100 μm, the thermal effect of infrared is small. For this reason, the synergistic effect of infrared & charge penetration in the composite magnet type using conventional infrared and charged particles can hardly be expected.

  The present inventor has solved the drawback that conventional medical medical devices using piezoelectric pyroelectric materials are limited in time due to the penetration effect of charged particles and infrared rays into the human body, and charged particles that are always effective when worn on the body. And a medical device capable of emitting infrared rays was proposed in Japanese Patent Application No. 2006-241359. The health care device according to this proposal is characterized in that the composite carbon particles having SP3 structure and SP2 structure synthesized by shock wave are arranged on the metal or non-metal human contact surface side constituting the health care device. And this health care device has the feature which can always radiate | emit effective charged particle and infrared rays, when mounting | wearing.

  However, continued research after filing revealed the following facts. In other words, diamonds produced by the explosion method are usually composed of a central SP3 structure (diamond structure) and an outer SP2 structure (graphite structure). This is because part of the SP3 structure returns to the SP2 structure when the pressure is high and the pressure is low. And by measuring the electrical resistance, it was found that the SP3 carbon particles synthesized by the shock wave have an energy level around the impurity level of 0.38 eV. The wavelength of infrared rays emitted when electrons excited to this energy level are stabilized is 4-10 μm. As a result, it became clear that all the effective electrons and infrared rays emitted from the composite carbon particles having the SP3 structure and the SP2 structure synthesized by the shock wave are emitted from the SP3 structure of the central core. On the other hand, since the SP2 structure is an electrical conductor, the electrons emitted from the SP3 structure are short-circuited to reduce the amount of emission from the carbon particles. Moreover, since the SP2 structure is an electric conductor having an energy width of 0, it absorbs infrared rays of all wavelengths. Therefore, infrared rays having a wavelength of 4 to 10 μm, which is emitted from a temperature of 300 to 400 ° C. and has a large thermal effect, are absorbed.

  The present invention has been made on the basis of the above-mentioned findings, and the problem is to provide a health care device that can emit charged particles and infrared rays that are always effective when worn on the body with higher efficiency. is there.

In order to solve the above-mentioned problem, the present invention uses a metal band constituting a health medical device or a carbon particle having an SP3 structure synthesized by a shock wave (hereinafter, simply referred to as “SP3 structure carbon particle”). The non-metallic band is disposed on the human body contact surface side (Claim 1).
When the health care device arranged in this way is used on the human body, the human body contact surface has a heating effect due to body temperature and a cooling effect due to the metal or nonmetal constituting the health care device. Due to temperature differences, high-efficiency infrared and charged particle emission effects are always maintained when worn as a health care device.

  In order to prepare SP3 structure carbon particles in a health care device, the SP3 structure carbon particles are mixed with an epoxy resin or a low-melting glass powder, and coated on a metal or non-metal human contact portion constituting the health care device and heated. It may be cured, or SP3-structured carbon particles may be mixed or adhered to the cloth or fiber (claim 2). As another method of use, a product obtained by coating the surface of a magnetic material with resin or glass and coating or integrally molding it as a mixed powder can be expected to have a combined effect of infrared rays, charged particles, and lines of magnetic force. ).

As a specific example, the method for obtaining the SP3-structured carbon particles is to explode a high-performance CB explosive in a sealed container to instantaneously generate a temperature of 2 million atmospheres and several thousand degrees, and the SP3-structured carbon particles are obtained. After synthesizing or putting carbon fine powder and Cu powder into a container and igniting the explosive set on the top, the same pressure temperature is applied to the powder mixture to change the crystal structure of the carbon, and then the metal powder is added. Dissolve with acid to obtain SP3 structure carbon particles. The particles may be covered with a carbon film having an SP2 structure in the cooling process after production. The carbon film having the SP2 structure may be heated with heated concentrated nitric acid or heated supercritical water as necessary. Remove. (See Non-Patent Documents 1 and 2). In the present invention, a carbon film having an SP2 structure is not necessarily required.

  The carbon powder obtained by the shock wave method contains impurities included in the particle manufacturing process, particularly nitrogen contained in the explosive, and is likely to be an N-type semiconductor. In addition, the solid band structure is disturbed by the influence of the strain inside the particle due to the pressure at the time of explosion, and has an impurity level of 0.2-0.4 eV, and therefore has electrical conductivity. Further, since the powder has a special SP3 structure, the present inventor has found that the infrared radiation ability and the charged particle emission ability are 5 to 10 times greater than those of conventional tourmaline and the like. Ordinary single crystal diamond has a forbidden band width of 5.5 eV and a specific resistance of 10E16Ω at room temperature, which is a nearly perfect insulator. However, the semiconductor SP3 structure carbon particles used in the present invention have a specific resistance of 10Ω depending on the manufacturing conditions. A value on the order of −10E10Ω can be obtained. A diamond that is close to an insulator and has a large specific resistance has a low impurity level density, so that the charge is not easily excited beyond the bandwidth when heated to about body temperature. Less emitted light is emitted when charged particles fall into the valence band.

Furthermore, SP3 structure carbon particles are coated in the form of a mixture such as resin on the human body contact surface of a health care device component composed of a semiconductor thermoelectric element, magnet, or piezoelectric pyroelectric material, or SP3 structure carbon particles are coated with the material powder. It is preferable to arrange a composite magnet that is mixed with and integrally molded (claim 3-4). Specifically, a hole is made in an oxide or rare earth magnet, a particle is embedded in the center, or a metal health medical device surface that emits a magnetic field line is coated with a mixture with an organic or inorganic binder, or composite spraying, etc. A coating method can be proposed. In some cases, the surface of the magnet material may be coated with the material of the present invention.
Thereby, in addition to the charged particle penetration effect, it is possible to further improve the health care effect on the body by utilizing the synergistic action of infrared rays and magnetic lines of force.

  In addition, a band-shaped health medical device in which magnet powder is kneaded into a semi-hard magnetic material or cloth having an external magnetic field of 400 G or less with good workability is formed, and SP3-structured carbon particles are adhered to the surface of the band. It may be used (Claim 5). A health medical device that generates a 400-1500G magnetic field using a normal magnetic material is a strong magnetic field, and thus cannot be used for a human body part that affects an arm or a cardiac pacemaker. It can also be used on the human body that affects the arm and heart pacemaker.

  According to the first aspect of the present invention, the charged charged particle penetration effect based on the electric field generated by the excited charged particles due to the body temperature of the carbon particles having the SP3 structure and the temperature difference between the human body contact surface side and the outside air contact surface side of the health care device and infrared rays Since the radiation effect is used, the effect of charge and infrared radiation can be expected at all times when the health care device is worn. Accordingly, the effect of increasing the human body temperature is greater than that of the conventional product.

  According to the invention of claim 2, SP3 structure carbon particles can be used by mixing or adhering to the fiber, or can be used by mixing with resin or glass bond material and adhering to the surface of the health care device and curing treatment. The degree of freedom in the shape of use is great.

  According to the invention of claim 3, since the SP3-structured carbon particles are used by coating the surface of the health care device, the required amount of carbon powder is small, and the cost merit is large.

  According to the invention of claim 4, SP3 structure carbon particles can be mixed with magnetic material powder and piezoelectric pyroelectric material powder and integrally molded with resin or glass bond material, so that mass productivity is improved. Moreover, in addition to the charge penetration effect, a synergistic effect of magnetic field lines and infrared rays can be expected, and the effect on the human body is further improved.

  According to the invention of claim 5, a synergistic effect is expected even if it is used for a magnetic metal band such as a bracelet or a ring, or a band kneaded with magnetic powder, which radiates an external magnetic field of 400G or less constituting a health care device. Yes, there is no restriction on the place of use. This is also because the infrared radiation and charge penetration effect due to the special semiconductor structure of the SP3 structure carbon particles is large.

  As one embodiment of the present invention, SP3-structured carbon particles are mixed with a resin or glass bond agent, and a liquid semi-finished product is injected into a hole formed in a metal band constituting a health care device and cured by heating. . As another embodiment, the semi-finished product was coated on a surface of a magnet or the like used in a medical device and cured by heating. In either case, in order to generate an electric field due to the temperature difference between the excited carrier and the carrier due to the human body temperature, an element using SP3 structure carbon particles was placed on the human body contact surface of the medical device so as to be in close contact with the human body. This provided a sustained infrared and charged particle penetration effect. That is, the infrared radiation effect and the charged particle penetration effect were enhanced as compared with the conventional product.

  In the case of coating, it is also possible to use a mixed spray technique without using a binder. When the combined effect with the magnetic field lines is not required, the surface of the cloth may be mixed with an adhesive and coated, or may be mixed with or attached to the fibers constituting the cloth.

  As the infrared radiation material for the insulator, tourmaline, black quartz and the like have been conventionally used, but the use of carbon particles produced by an explosive force such as CB explosive is most preferable. These carbon particles are usually manufactured as particles of a composite structure in which the core is an SP3 semiconductor structure and the surface is covered with a thin graphite-like layer close to the SP2 structure, and the surface SP2 film is dissolved and removed depending on the application. The In the application of the present invention, the SP2 graphite layer is not required because it short-circuits the generated charged particles.

  During the manufacturing process, the nitrogen component in the explosive enters as an impurity, and the band structure as a semiconductor has a special structure that can produce an impurity level with a low energy difference of 0.1-0.4 eV in the forbidden band. Infrared radiation is large at a wavelength effective for temperature, and the effect of generating charged particles by heating is also large.

  FIG. 1 shows the characteristics of the infrared radiation ability of three members such as SP3 structure carbon particles, composite carbon particles having SP3 structure and SP2 structure, and tourmaline used in normal health care devices. An epoxy resin mixed with 10 wt% SP3 carbon particles (Example), an epoxy resin mixed with 50 wt% tourmaline (Comparative Example 1), and an epoxy resin having 10 wt% SP3 and SP2 structures Infrared spectral radioactivity was measured in a 40 ° C. environment for samples obtained by heating and coagulating carbon particles (Comparative Example 2) at 150 ° C.

  Although the compounding amount with respect to an epoxy resin is 1/5 of the comparative example 1, an Example has a large infrared radiation amount of 4-10 micrometers mainly from the object heated to 200-400 degreeC. Moreover, since the surface of the carbon particle of the present invention using carbon particles having only the SP3 structure is coated with a bond resin, the spectral emissivity is improved only by about 3% as compared with Comparative Example 2. Depending on the type of coupling agent used, higher spectral emissivity can be expected.

  FIG. 2 shows a change in resistance due to carriers generated by heating near the body temperature. The measurement method was to press-mold carbon particles to 5 mmφX5 mmt, attach a Cu electrode and a thermocouple, and measure resistance and temperature while heating with an electric heater. The electrical resistance value was halved at a temperature of 23-48 ° C. This indicates that the charged particles are doubled by heating. The activation energy calculated from the temperature coefficient of electrical resistance change is 0.37 eV, indicating that the carbon particles have semiconductor properties. As a semiconductor infrared radiation material, even if Ge, InSb, etc., which have a large infrared radiation with a wavelength of 100 μm and have a high performance index as a thermoelectric element, can be expected to have further effects.

  Carbon particles having an SP3 structure explosively molded by the shock wave method have a particle size as small as 100 nm to 3 nm due to the production method and a large specific surface area per unit weight, so that the influence of surface energy on the human body is large. When applied to a health care device, the effect can be expected. Moreover, it is easy to contain nitrogen resulting from the explosive used as an impurity, exhibits N-type semiconductor characteristics, has a wide electric conductivity of 10-10E15, and has a charge mobility and carrier concentration as a principle, such as a piezoelectric element such as Tolmarie. Since it is large compared to pyroelectric materials, it also has a large infrared radiation charged particle radioactivity, which is highly effective as a health care device.

Next, the temperature rise effect of body temperature when using a medical device using composite carbon particles having different SP3 structure and SP2 structure content ratios was measured and compared. When the temperature increase effect when the content ratio of the SP3 structure and the SP2 structure is 9 to 1, the measurement result is as follows.
SP3 SP2 Temperature rise ratio Manufacturer
9 1 1 Made by domestic S company
7 3 0.6 Made in Russia
5 5 0.4 Made in China The ratio of SP3 and SP2 is not essential by the manufacturer, but is due to the removal process of SP2.

[Example]
20 holes of 3 mmφ × 1.8 mmt were made on the human body contact surface side of a pure stainless steel and magnetic stainless steel bracelet having a radiation magnetic field of 150 G, and an epoxy resin mixture containing 50 wt% tourmaline was injected into the holes, and 10 wt% of SP3 carbon particles. Each of the epoxy resin mixtures containing was poured into holes and dried at 150 ° C. for 1 hour to make health care devices. Each was attached to the arm, and the temperature rise after 15 minutes was measured with a thermograph.

[Measurement result]
Health care equipment Tourmaline (50wt%) SP3 carbon particles (10wt%)
Pure titanium bracelet 0.2 ℃ 0.6 ℃
Magnetic stainless steel bracelet 0.3 ℃ 1.0 ℃

  From the above body temperature rise measurement results, it can be seen that the effect of heating the SP3 structure carbon particles according to the present invention on the human body is excellent. The effect is particularly great when used in combination with a weak magnetic field. In addition, when removing graphite (SP2 structure) with supercritical water from composite carbon particles having SP3 structure and SP2 structure synthesized by shock wave, it is completely removed, but when oxidizing graphite with concentrated nitric acid to remove graphite. Leaves about 1% SP2 structure by weight. However, even if the SP2 structure is slightly present, the infrared heating effect and the charged particle permeation effect are far superior to health care devices using composite carbon particles that have not been subjected to the SP2 structure removal treatment. Therefore, although the present invention does not make the SP2 structure an essential requirement, a case where a slightly remaining material is used also falls within the scope of the claims of the present invention.

  The compound for the human body with the medical device or the magnetic field line using the infrared heating effect by the body temperature heating and the charged particle permeation effect of the semiconductor particles having the SP3 structure mainly composed of carbon prepared by using the shock wave by the explosion of the present invention Health-care devices that use the action are molded into the required shape, such as general warm clothing as fibers, and necklaces, bracelets, rings, ankles, underwear, socks, abdomen, sheets, pillows, and bedding. In addition to being used for the human body, it can also be applied as an animal medical device. In particular, since the combined effect with a magnetic field of 400 G or less, which has been considered ineffective in the past, is great, it can be used even in the vicinity of an electronic medical device in which the use of a magnetic material is prohibited, such as a cardiac pacemaker. Useful. Because many pet animals have a higher body temperature than the human body, they seem to be particularly effective.
