Can do.

JP 2011-83394 A

  However, in the magnetic therapy device of Patent Document 1, the permanent magnet does not move unless the user moves. For example, when the magnetic therapy device is used at the time of sleeping of the user, the user hardly moves, so that the permanent magnet moves and hardly generates a variable magnetic field. Thus, when used in a state where the user does not move, the magnetic therapy device of Patent Document 1 cannot be expected to have a sufficient magnetic therapy effect.

  The present invention has been made in view of the above problems, and can be used by being attached to a user's skin, and can generate a variable magnetic field in a wide range even when the user does not move. An object of the present invention is to provide a portable variable magnetic field magnetic therapy device.

  The variable magnetic field magnetic therapy device of the present invention is a portable variable magnetic field magnetic therapy device that is used by being attached to the skin of a user when the internal space and the variable magnetic field magnetic therapy device are attached to the skin.

  In addition, the magnet unit includes a plurality of magnets each having a magnetic pole direction extending substantially perpendicular to the bottom surface of the container, and the plurality of magnets are separated from each other along the rotation direction of the magnet unit. Among the plurality of magnets, magnets adjacent to each other in the rotation direction of the magnet portion have magnetic pole directions that are substantially opposite to each other, and the magnet portion generates an alternating magnetic field by the rotation of the magnet portion. It is preferably configured to generate.

  Moreover, it is preferable that the magnet provided in the said magnet part is formed in the substantially partial annular shape extended along the rotation direction of the said magnet part.

  According to the present invention, a portable variable magnetic field magnetic treatment that can be used by being attached to the user's skin and can generate a variable magnetic field in a wide range even when the user does not move. Can be provided.

It is a top view which shows the internal structure of the magnetic field magnetic therapy apparatus of FIG. It is a bottom view which shows the internal structure of the magnetic field magnetic therapy apparatus of FIG. (A) is a bottom view of the magnet part of the magnetic field magnetic therapy apparatus of FIG. 1, (b) is the sectional view on the AA line of (a). It is a figure which shows typically the magnetic flux line produced | generated by the magnet part of the magnetic field magnetic therapy apparatus of FIG.

  Hereinafter, a variable magnetic field magnetic therapy device according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, when the terms “upper side” and “lower side” are used, they are opposite to the skin when the magnetic field magnetic therapy device is attached to the user's skin, respectively. The side means “upper side” and the skin side means “lower side”.

  A variable magnetic field magnetic therapy device (hereinafter simply referred to as “therapeutic device”) 1 according to an embodiment of the present invention (hereinafter referred to as “this embodiment”) is applied to the skin S of a user as shown in FIG. Installed and used as a portable type. The treatment device 1 is used by being attached to the user's skin S, thereby giving a fluctuating magnetic field to the surface of the user's skin S and to the body in the vicinity of the surface of the user's skin S, thereby providing a magnetic treatment effect. The treatment device 1 can be used for any magnetic therapy purpose that can utilize a magnetic therapy effect such as promoting blood circulation or improving metabolism. Moreover, the position to which the treatment device 1 is attached is not particularly limited, and may be any position as long as the magnetic treatment effect can be used, such as a shoulder or a waist skin.

  As shown in FIG. 1, the treatment device 1 includes a container 2 having an internal space 21 and a bottom surface 24, a magnet unit 3 rotatably accommodated in the internal space 21, and a direction substantially perpendicular to the bottom surface 24. And a rotational drive mechanism 4 that rotationally drives the magnet portion 3 in a plane substantially parallel to the bottom surface 24 with the rotational axis X extending in the direction of the center. The therapeutic device 1 varies in a wide range even when the user does not move because the magnet unit 3 is rotationally driven by the rotational drive mechanism 4 in a plane substantially parallel to the bottom surface 24. A magnetic field can be generated.

  As shown in FIG. 1, the container 2 rotatably accommodates the magnet unit 3 in an internal space 21, and directly or indirectly on the skin S when the treatment device 1 is attached to the user's skin S. It is a member to contact. In this embodiment, as shown in FIGS. 1 to 3, the container 2 is formed in a substantially cylindrical shape as a whole, and surrounds the internal space 21. The upper surface 22, the side surface 23, and the treatment device 1 is the skin S. And a bottom surface 24 that directly or indirectly contacts the skin S when attached to the skin. However, the container 2 only needs to have an inner space 21 having a size capable of rotatably accommodating the magnet unit 3 and a bottom surface 24 that directly or indirectly contacts the skin S. Other shapes such as a prismatic shape or a substantially conical shape may be used.

  The treatment device 1 can be attached to the skin S of the user so that the bottom surface 24 is in direct contact with the skin S by an attaching means such as an adhesive tape or a band provided so as to cover from above. For example, an adhesive sheet may be provided between the bottom surface 24 and the skin S and attached to the user's skin S so that the bottom surface 24 indirectly contacts the skin S. Thus, the treatment device 1 may be attached to the skin S so that the bottom surface 24 of the container 2 is in direct or indirect contact with the skin S, and the attachment method is not particularly limited. Is preferably attached to the skin S so that the bottom surface 24 is in direct contact with the skin S.

  The molding material of the container 2 can maintain the shape of the internal space 21 when receiving a force from the outside, and can easily transmit the magnetic flux lines generated by the magnet unit 3 (the magnetic field generated by the magnet unit 3). Is not particularly limited, and examples thereof include acrylonitrile butadiene styrene (ABS), polycarbonate acrylonitrile butadiene styrene (PC-ABS), polyethylene (PE), and polyethylene terephthalate (PET). A synthetic resin material such as can be suitably used. In particular, since the strength of the magnetic field rapidly attenuates as it moves away from the magnet unit 3, the magnet unit 3 is preferably provided as close to the skin S as possible, and the bottom surface 24 is preferably formed as thin as possible.

  The magnet unit 3 generates a variable magnetic field by being rotated by the rotation driving mechanism 4 in the internal space 21 of the container 2 rotatably accommodated. In the present specification, the term “variable magnetic field” means a magnetic field in which the direction and strength of the magnetic field vary. In the treatment device 1, the magnet unit 3 is rotated by the rotation drive mechanism 4 to generate a variable magnetic field, thereby giving a large stimulus to the blood vessels and tissues in the body near the surface of the skin S and the surface of the skin S, and high magnetic properties. A therapeutic effect can be exerted. The configuration of the magnet unit 3 is not particularly limited as long as the magnet unit 3 is rotatably accommodated in the internal space 21 of the container 2 and can be rotated by the rotation driving mechanism 4 to generate a fluctuating magnetic field. A preferred configuration to be described can be employed.

  With reference to Fig.4 (a), FIG.4 (b), and FIG. 5, the magnet part 3 of the treatment device 1 which concerns on this embodiment is demonstrated. The magnet unit 3 includes a magnetic shield unit 31 and magnets 32a and 32b. The magnetic shield unit 31 has a magnetic field generated by the magnets 32a and 32b opposite to the bottom surface 24 of the container 2 (in FIG. 4A). It is configured to shield leakage to the back side of the drawing, the upper side in FIG. 4B and the upper side in FIG. More specifically, as shown in FIG. 5, the magnet unit 3 is configured such that the magnetic flux lines M generated by the magnets 32 a and 32 b face in the direction facing the side opposite to the bottom surface 24 of the container 2, and the magnet unit 3. The direction in which the magnetic flux lines M extending in the radial direction inside and outside of the rotating track extend in the direction toward the bottom surface 24 of the container 2 is changed by the magnetic shield portion 31. Therefore, the treatment device 1 can avoid magnetic field leakage to the upper side opposite to the skin S, that is, in a direction away from the user. Since the treatment device 1 is attached to the skin S and used as a portable device, for example, the user may be damaged by the influence of the leakage magnetic field when using the treatment device 1. You may encounter a scene where you have to use. Even in such a case, the user can use the treatment device 1 without worrying about damage to the magnetic card. Furthermore, since the magnet unit 3 is configured so that the magnetic field does not leak in directions other than the bottom surface 24 side of the container 2, it is possible to prevent magnetic field leakage to the rotation drive mechanism 4 and the electronic substrate 6 described later. Malfunctions due to the magnetic field and unnecessary energy consumption are avoided. Further, the magnetic flux lines M generated by the magnets 32a and 32b extend intensively in the direction toward the bottom surface 24 of the container 2, thereby concentrating on the skin S surface on the lower side of the magnet portion 3 and the body in the vicinity of the skin S surface. Therefore, even if the magnets 32a and 32b are made small, a larger magnetic treatment effect can be obtained.

  The magnetic shield unit 31 includes a material capable of shielding a magnetic field, and shields the magnetic field generated by the magnets 32 a and 32 b from leaking to the side opposite to the bottom surface 24 of the container 2. In this embodiment, the magnetic shield part 31 has a substantially U-shaped cross section substantially perpendicular to the rotation direction of the magnet part 3 as shown in FIGS. 4A and 4B, and the magnet part as a whole. 3 is formed in a substantially annular shape extending along the rotation direction. More specifically, the magnetic shield part 31 includes a magnet holding part 31a formed in a substantially annular substantially flat plate shape, and a skin S side (on the bottom face 24 side of the container 2) from the outer periphery in the radial direction of the magnet holding part 31a. And an inner peripheral portion 31c extending from the inner periphery on the inner side in the radial direction of the magnet holding portion 31a to the skin S side (the bottom surface 24 side of the container 2). The magnetic shield part 31 is fixed to the shaft X1 by a fixing part 34 which is fixed to the inner peripheral part 31c and provided with a hole H into which the shaft X1 (see FIG. 1) can be inserted. In the present embodiment, magnets 32a and 32b are provided on the skin S side of the magnet holding portion 31a of the magnetic shield portion 31 and between the outer peripheral portion 31b and the inner peripheral portion 31c of the magnetic shield portion 31, and the magnet 32a, The direction of the magnetic flux line M generated from 32b is changed, and the magnetic field generated by the magnets 32a and 32b is prevented from leaking to the upper side of the magnetic shield part 31 and radially outside and inside. However, the magnetic shield part 31 only needs to be able to shield the magnetic field generated by the magnets 32a and 32b from leaking to the side opposite to the bottom surface 24 of the container 2 (or in a direction other than the bottom surface 24 side). Is not particularly limited, and can be appropriately changed according to the shapes of the magnets 32a and 32b.

  The material included in the magnetic shield part 31 that can shield the magnetic field is not particularly limited, but a high magnetic permeability material can be used, for example, permalloy, pure iron, silicon steel, or the like. Can do. Among these, a permalloy excellent in coercive force is preferable, and a Mo-based permalloy excellent in coercive force is more preferable.

  In this embodiment, as shown in FIG. 4A and FIG. 4B, the magnet portion 3 has a plurality of magnetic pole directions (in this embodiment, each having a magnetic pole direction extending substantially perpendicular to the bottom surface 24 of the container 2. 2) magnets 32a and 32b. Each of the plurality of magnets 32a and 32b is arranged to be separated from each other along the rotation direction of the magnet unit 3, and among the plurality of magnets 32a and 32b, the magnets 32a and 32b adjacent to each other in the rotation direction of the magnet unit 3. Each has a magnetic pole direction that faces substantially opposite directions. In the present embodiment, the magnet 32a is magnetized so that the lower side is the N pole and the upper side is the S pole (the magnetic pole direction faces the upper side), and the magnet 32b is the S pole on the lower side and the N pole on the upper side. So that the magnetic pole direction faces downward. The magnet unit 3 includes a plurality of magnets 32 a and 32 b that are separated from each other and have magnetic pole directions that are substantially opposite to each other, thereby generating an alternating magnetic field by the rotation of the magnet unit 3. The magnet unit 3 includes a plurality of magnets 32a and 32b in which the respective magnetic pole directions are opposite to each other, so that the change in the magnetic field strength received by the skin S when the magnet unit 3 is rotated has the magnetic pole direction in the same direction. Compared with the case where a plurality of magnets are used, the size is almost doubled, and a larger alternating magnetic field can be generated. Furthermore, the magnetic pole direction of the magnets 32a and 32b used extends substantially perpendicular to the bottom surface 24 (and the surface of the skin S) of the container 2, so that the magnetic pole direction extends substantially parallel to the bottom surface 24 (and the surface of the skin S). Compared with the case where a magnet is used, the magnetic field strength in a direction substantially perpendicular to the surface of the skin S increases, and magnetism acts from the skin S surface to a deeper body. In addition, since the magnets 32a and 32b are separated from each other along the rotation direction of the magnet unit 3, when the magnet unit 3 rotates, blood vessels and internal tissues near the skin S surface and the surface of the skin S feel a magnetic field. No time, that is, time for relaxation without being affected by the magnetic field can be secured. Therefore, the blood vessel and the internal tissue near the skin S surface and the skin S surface can alternately repeat the relaxation and the tension more reliably. Giving great stimulation to tissues and exerting high magnetic therapeutic effect.

  In the present embodiment, the magnets 32a and 32b of the magnet unit 3 generate magnetic fields having substantially the same size and facing each other in the same location on the skin S when the magnet unit 3 rotates. It is configured. As shown in FIGS. 4 (a) and 4 (b), the magnets 32a and 32b are both formed in a substantially partial annular shape extending along the rotation direction of the magnet portion 3, and are both formed in the same size. . More specifically, each of the magnets 32a and 32b extends in the rotation direction of the magnet portion 3 by approximately ¼ circumference, and the inner circumference diameter thereof is formed in a substantially partial ring shape that is substantially half or more of the outer circumference diameter. Yes. In other words, the magnets 32a and 32b are formed in an arc-shaped belt shape with the fan-shaped radial inner side removed, and are arranged so as to form a substantially circular locus when the magnet portion 3 rotates. The magnet portion 3 may be formed to have a larger diameter as compared with the case where the magnets 32a and 32b are formed in a substantially partial ring shape (strip shape) and use the same amount of fan-shaped magnets. The magnetic force can be applied to more blood vessels near the surface of the skin S. Since a rare earth magnet capable of generating a strong magnetic field has a relatively large specific gravity, the volume that can be used in the treatment device 1 is limited, but it is small by forming the magnet in a substantially annular shape (band shape) as in this embodiment. Magnetic force can be applied to more blood vessels even in the volume, and a larger magnetic therapeutic effect can be obtained. Furthermore, since the magnet part 3 can be reduced in weight, the torque which the rotational drive mechanism 4 receives from the magnet part 3 can be made small, and the rotational drive mechanism 4 can be designed more compactly. Therefore, the treatment device 1 can be made smaller and can be easily attached to the skin S.

  As shown in FIGS. 4 (a) and 4 (b), the magnets 32a and 32b are provided via two hollow portions 33a and 33b having substantially the same shape and size as the two magnets 32a and 32b. The magnet unit 3 is disposed away from each other in the rotation direction. When the magnet part 3 having such an arrangement rotates at a constant speed, the magnet part 3 passes through the surface of the skin S in the order of the magnet 32a, the cavity part 33a, the magnet 32b, and the cavity part 33b (or vice versa) An alternating magnetic field having a single frequency with respect to the skin S surface is generated. Since the treatment device 1 generates an alternating magnetic field having a single frequency, it can expose the alternating magnetic field having a single frequency to the surface of the user's skin S and in the body tissue in the vicinity of the skin S surface. In addition, the cells in the tissue can be stimulated to bring about an effect of healing cell dysfunction such as inflammation.

  In the magnet unit 3 in the present embodiment, two magnets 32a and 32b are provided. However, if the magnet unit 3 can generate the alternating magnetic field having the single frequency described above, the number of magnets is one. Or three or more. At this time, the magnet part 3 has substantially the same shape as the magnet and has the same number of cavities, and the magnets and the cavities are alternately arranged along the rotation direction of the magnet part 3. A single frequency alternating magnetic field can be generated by rotation.

  The material of the magnets 32a and 32b is not particularly limited, and for example, neodymium, ferrite, samarium cobalt, an artificial magnetic material, or the like can be employed. However, the output level is preferably within the range of the certification standards of the Ministry of Health, Labor and Welfare.

  Referring to FIGS. 1 to 3 again, the rotation drive mechanism 4 includes an electric drive source 41 that generates a rotation drive force about a rotation axis Y that extends substantially perpendicular to the bottom surface 24, and the rotation drive force as a magnet unit. And a rotational driving force transmission mechanism 42 that transmits to the motor 3. The electric drive source 41 is provided apart from the magnet unit 3 in a plane substantially parallel to the bottom surface 24. That is, the electric drive source 41 is disposed so as not to overlap the magnet unit 3 along a direction substantially perpendicular to the bottom surface 24. Therefore, even if the electric drive source 41 is provided with a magnet, the influence of the magnet of the electric drive source 41 on the variable magnetic field generated from the magnet unit 3 on the skin S side can be suppressed to a small level. However, the rotation drive mechanism 4 is not limited to the above-described configuration as long as the magnet unit 3 can be rotated in a plane substantially parallel to the bottom surface 24 of the container 2. The magnet unit 3 may be disposed so as to overlap with the magnet unit 3 along a direction substantially perpendicular to the bottom surface 24 and may be directly connected to the magnet unit 3.

  The electric drive source 41 is driven by the power supply unit 5. More specifically, as shown in FIGS. 1 and 2, the electric drive source 41 is electrically connected to an electronic board 6 that is electrically connected to the power supply unit 5, and the electronic board is connected to the electronic board 6. 6 is supplied with electric power, and generates a rotational driving force around the rotation axis Y. The electric drive source 41 is not particularly limited as long as it can generate a rotational driving force electrically, and a known DC motor or the like can be used.

  In this embodiment, the power supply unit 5 is fixed to the container 2 so as not to be detached. The power supply unit 5 can be a replaceable battery, but can be prevented from being accidentally swallowed by a child by being fixed to the container 2 so as not to be removed. Here, the term “non-removable” means that it cannot be removed from the container 2, but it means that it cannot be removed during normal use. It does not mean that it cannot be removed until it needs to be removed for overhaul. In this embodiment, the power supply unit 5 is a secondary battery that can be charged via the USB terminal 7. Therefore, since the power supply part 5 can be charged easily, the treatment device 1 can be easily carried and carried. Moreover, since the power supply part 5 can be used repeatedly, the effort which replaces like a battery which is not rechargeable can be saved.

  In this embodiment, the rotational driving force transmission mechanism 42 is configured to decelerate the rotational speed of the electric driving source 41 when transmitting the rotational driving force generated by the electric driving source 41 to the magnet unit 3. More specifically, the rotational driving force transmission mechanism 42 is, as shown in FIGS. 1 and 2, a first gear 42 a fixed to a shaft Y <b> 1 extending along the rotational axis Y from the electric drive source 41 so as not to be relatively rotatable. And a second gear 42b that meshes with the first gear 42a, has a larger diameter and a larger number of teeth than the first gear 42a, and is fixed to the shaft X1 extending from the magnet portion 3 along the rotation axis X so as not to be relatively rotatable. And. In the treatment device 1, when the electric drive source 41 generates a rotational driving force, the shaft Y1 and the first gear 42a rotate around the rotational axis Y, and accordingly, the second gear 42b that meshes with the first gear 42a is provided. The magnet unit 3 that rotates about the rotation axis X together with the shaft X1 and is fixed to the shaft X1 so as not to rotate relative to the shaft X1 rotates about the rotation axis X. At this time, since the number of teeth of the first gear 42a is smaller than the number of teeth of the second gear 42b, the rotational speed of the electric drive source 41 is reduced and the magnet unit 3 is rotated. Can be rotated by rotation. Furthermore, even if the weight of the magnet part 3 increases, the torque received by the electric drive source 41 from the magnet part 3 can be reduced.

  As shown in FIG. 1 and FIG. 2, the treatment device 1 is further electrically connected to the electronic board 6 and lights up when the power supply unit 5 is in a charged state, and charging of the power supply unit 5 is completed. Then, an LED lamp 8 configured to be turned off is provided. Therefore, since the treatment device 1 can easily determine whether the power supply unit 5 is in a charged state or whether the power supply unit 5 has completed charging, the charging operation is facilitated and the battery is out of charge during use. It becomes easy to avoid such a situation. In addition, the treatment device 1 further includes a switch 9 that is electrically connected to the electronic board 6 and for turning on / off the electric drive source 41. In the treatment device 1, when the user turns on the switch 9, the magnet unit 3 starts to rotate and brings about a magnetic treatment effect.
