Description

  The present invention relates to a health care device that synergistically uses a magnetic field effect, a far-infrared effect, a mid-infrared effect, and a charge injection effect on the skin.

Magnetic field lines generated from permanent magnets have the effect of promoting blood circulation to the human body. Therefore, a type of health medical device in which a magnetic material is chipped into a predetermined shape and attached to the human body with an adhesive tape or the like is widely used. . As a magnet material, a rare earth magnet having a BHmax of 20 to 30 is recently used from a conventional ferrite magnet having a BHmax of about 3.
Infrared rays also have blood circulation promoting effects, nerve fiber activation effects, analgesic effects, and the like, and are known to have a positive effect on the human body. Like infrared magnets, they are used in the form of chips that are attached to affected areas. As the infrared radiation material, Ge that emits far infrared rays is used alone.
Recently, a fatigue recovery effect due to skin penetration of charged particles having a negative charge has been recognized, and tourmaline is processed and used in the same manner as a magnet as the charged particle emitting material.

  Recently, a composite magnet in which a magnet powder and an infrared radiation material powder are mixed has been proposed aiming at a synergistic effect of a magnetic field effect and an infrared effect, and used as a health care device (for example, Patent Document 1, Patent). Reference 2).

Tourmaline or the like is also used as an infrared radiation material, but the effective infrared wavelength of tourmaline is 10 to 15 μm, and mid-infrared rays with a wavelength of 2.5 to 25 μm act relatively on the surface of the skin to exert its effect. Since the magnetic field lines have a great skin penetration effect, they penetrate into the body. For this reason, infrared rays and magnetic lines of force did not sufficiently exhibit the synergistic effect inside the body (for example, Patent Document 3).
JP-A-5-347206 JP-A-10-241924 JP 2001-126908 A

  The present invention has been made in view of the above circumstances, and the problem to be solved is that infrared rays and magnetic lines of force sufficiently exert the synergistic effect inside the body, promoting blood circulation inside the human body, restoring muscle fatigue, An object of the present invention is to provide a health care device that can provide an analgesic effect.

In order to solve the above-mentioned problems, the health care device of the present invention is obtained by mixing a rare earth magnet powder and a far infrared radiation material, a mid infrared radiation and a piezoelectric pyroelectric material powder together with a binder, and molding and heating the mixture. It is characterized by comprising a composite magnet (claim 1).
It is desirable to use a semiconductor having a forbidden band width of 0.7 eV or less as the far infrared radiation material, and to use a ferroelectric material having spontaneous polarization as the mid infrared radiation and the piezoelectric pyroelectric material.
Further, as far-infrared radiation materials, one or more of Ge (germanium), InSb (indium antimonide), PbS (lead sulfide) and HgTe (mercury telluride) can be used as intermediate infrared radiation and piezoelectric pyroelectric. It is desirable to use one kind or plural kinds of tourmaline, barium titanate, lead zirconate titanate, crystal, ZnO, lithium niobate and LBO (LiB3O5 lithium boron oxide) crystal as a material (Claim 3).
The total volume addition amount of the far-infrared radiation material powder, the mid-infrared radiation material and the piezoelectric pyroelectric material powder to the magnet powder is 10 to 70%, and the volume ratio of the blend amounts of both infrared radiation materials is 5% or more. Desirable (Claim 4).
That is, the present invention adds a mid-infrared radiation effect and a piezoelectric pyroelectric effect in accordance with the penetration effect of magnetic field lines into the deep part of the human body, and at the same time provides a far-infrared radiation effect with a wavelength of 25 μm or more emitted from a semiconductor with a narrow band gap. It is intended to be used.

According to the invention of claim 1, a composite magnet obtained by mixing rare earth magnet powder and far infrared radiation material, intermediate infrared radiation and piezoelectric pyroelectric material powder together with a binder and molding and heating the mixture is used. Therefore, the magnetic field lines and infrared rays are sufficiently exerted to the inside of the body, and in combination with the charge penetration action, blood circulation promotion, muscle fatigue recovery, and analgesic effects are obtained within the human body.
When a semiconductor having a band gap of 0.7 eV or less is used as the far infrared radiation material and a ferroelectric material having spontaneous polarization is used as the intermediate infrared radiation and the piezoelectric pyroelectric material as in the invention of claim 2, the semiconductor From the far infrared ray of 25 μm or more, the infrared ray of 25 μm or less and the electric charge are activated by the body temperature from the ferroelectric material having spontaneous polarization.
As in the invention of claim 3, one or more of Ge, InSb, PbS and HgTe are used as the far infrared radiation material, and tourmaline, barium titanate, lead zirconate titanate as the intermediate infrared radiation and piezoelectric pyroelectric material, When one or more of quartz, ZnO, lithium niobate and LBO crystals are used, far infrared rays, intermediate infrared rays and electric charges are generated simultaneously, and far infrared rays of 25 μm or more are infrared rays of 25 μm or less deeper than the human body. Heats up blood circulation near the surface of the skin, and simultaneously generated charged particles penetrate into the muscles and promote fatigue recovery.
As in the invention of claim 4, the total volume addition amount of the far infrared radiation material powder, the mid infrared radiation and the piezoelectric pyroelectric material powder to the magnet powder is 10 to 70%, and the volume ratio of the blending amount of both infrared radiation materials is When both are 5% or more, when the magnet is a rare earth magnet, an infrared superposition effect and a charge penetration effect with a long and short wavelength can be reliably obtained.

In order to carry out the present invention, intermediate infrared radiation and piezoelectric pyroelectric materials that generate infrared rays and charged particles having a wavelength of 2.5 to 25 μm, and far infrared radiation materials having a wavelength of 25 μm or more are powdered and mixed with magnet material powder. The composite magnet is then molded and used as a health device.
Since the piezoelectric pyroelectric material is usually an insulator having a forbidden band width of 2 eV or more, charged particles and intermediate infrared rays having a wavelength of 2.5 to 25 μm are simultaneously emitted by activation by the human body. Since the human body penetration force of infrared rays increases as the wavelength becomes longer, the human body penetration effect of magnetic lines of force can be sufficiently exhibited by using the infrared effect of both wavelengths together.

  The magnetic line density that exhibits a sufficient medical effect is 800 to 2000G. Since the ferrite magnet has a small energy product BHmax, the surface magnetic flux density may be less than 800 G when a far-infrared emitting material and a mid-infrared emitting material (hereinafter sometimes referred to as ceramics) are combined at the same time. Many are difficult to use. The ratio of the addition amount of the ceramic powder volume to the magnet powder volume is preferably in the range of 10 to 70%. In the case of a barium ferrite magnet, the required magnetic flux density cannot be obtained because BHmax is less than 0.3 when the amount of ceramic powder added is 60%.

  On the other hand, in the case of rare earth magnets, when the ceramic content is 10% of the total volume, BHmax is about 8, and a surface magnetic flux density of 1500 G can be sufficiently secured. Further, the BHmax of the composite magnet in the case of 70% of the total volume is about 2.5, and a minimum surface magnetic flux density of 800 G can be secured. Therefore, the blending amount of the ceramic powder with respect to the total volume is limited to 10 to 70%.

  The mixing ratio of the far-infrared material powder (A) to the mid-infrared and piezoelectric pyroelectric material (B) is preferably 5-95%. When either A or B material is less than 5%, the effect of superimposing long and short wavelength infrared rays is reduced. In order to sufficiently exhibit the effect of the charged particles as a blending ratio, the blending ratio of the mid-infrared and piezoelectric pyroelectric materials to the far-infrared emitting material is preferably 60% or more. Since the lifetime and mobility of charged particles generated by activation by the human body are short, it is necessary to secure the amount of piezoelectric pyroelectric material in order to exert the muscle penetration effect of charged particles.
