Description

The present invention relates to a fluctuating magnetic field magnetic therapy device. More specifically, the present invention relates to a portable variable magnetic field magnetic therapy device that is attached to the user's skin and used to generate a variable magnetic field.

Conventionally, in order to improve blood circulation of a user and alleviate the symptoms of stiff shoulders and low back pain, a magnetic therapy device that uses an adhesive plaster or the like with a fixed magnet attached to the user's skin has become widespread. Such a magnetic therapy device is compact and can be attached directly to the user's skin for use, so that the user can use it in any condition, whether active or sleeping. The therapeutic effect can be effectively obtained.

However, in such a magnetic therapy device, the magnet is fixed at a specific position with respect to the skin, and the magnetic field is fixed (a static magnetic field is formed), so that a large stimulus is given to blood vessels and tissues in the body, which is high. There is a problem that the magnet must be enlarged to increase the magnetic force in order to exert the magnetic therapy effect. To solve such a problem, for example, Patent Document 1 proposes a magnetic therapy device in which a permanent magnet is movably housed in a protective case portion. When the magnetic therapy device of Patent Document 1 is attached to the user's skin and used, the permanent magnet moves in the protective case according to the movement of the user, so that a fluctuating magnetic field is generated and a high magnetic therapy effect is exhibited. can do. In particular, since this magnetic therapy device is configured so that the permanent magnet moves in a plane parallel to the skin, it can be formed thin and easily attached to the skin, and also generates a fluctuating magnetic field over a wide range. Can be done.

Japanese Unexamined Patent Publication No. 2011-83394

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 bedtime of the user, the user hardly moves, so that the permanent magnet hardly moves and a fluctuating magnetic field is hardly generated. When the user is used in such a state that 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 the skin of the user, and can generate a fluctuating magnetic field in a wide range even when the user does not move. It is an object of the present invention to provide a portable variable magnetic field magnetic therapy device.

The variable magnetic field magnetic treatment device of the present invention is a portable variable magnetic field magnetic treatment device used by being attached to the user's skin, and when the internal space and the variable magnetic field magnetic treatment device are attached to the skin. A container having a bottom surface in contact with the skin, a magnet portion rotatably housed in the internal space, and a rotation axis extending in a direction substantially perpendicular to the bottom surface. The magnet portion is provided with a rotation drive mechanism for rotationally driving the magnet portion in a parallel plane, the magnet portion includes a magnetic shield portion and a magnet, and the magnetic shield portion receives a magnetic field generated by the magnet of the container. It is characterized in that it is configured to block leakage to the side opposite to the bottom surface.

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

Further, it is preferable that the magnet provided in the magnet portion is formed in a substantially annular shape extending along the rotation direction of the magnet portion.

According to the present invention, a portable variable magnetic field magnetic therapy that can be attached to the user's skin and can generate a fluctuating magnetic field in a wide range even when the user does not move. A vessel can be provided.

It is a side view which shows the internal structure of the variable magnetic field magnetic therapy apparatus which concerns on one Embodiment of this invention. It is a top view which shows the internal structure of the variable magnetic field magnetic therapy apparatus of FIG. It is a bottom view which shows the internal structure of the variable magnetic field magnetic therapy apparatus of FIG. (A) is a bottom view of the magnet portion of the fluctuating magnetic field magnetic therapy device of FIG. 1, and (b) is a sectional view taken along line AA of (a). It is a figure which shows typically the magnetic flux line generated by the magnet part of the fluctuating magnetic field magnetic therapy apparatus of FIG.

Hereinafter, the variable magnetic field magnetic therapy device according to the 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 variable magnetic field magnetic therapy device is attached to the user's skin and used. The side shall mean "upper side" and the skin side shall mean "lower side".

The fluctuating magnetic field magnetic therapy device (hereinafter, simply referred to as “therapeutic device”) 1 according to one embodiment of the present invention (hereinafter, “the present embodiment”) is applied to the skin S of the user as shown in FIG. Attached and used as a portable type. When the treatment device 1 is attached to the user's skin S and used, a fluctuating magnetic field is applied to the user's skin S surface and the body near the skin S surface to bring about a magnetic therapeutic effect. The treatment device 1 can be used for any magnetic therapy purpose that can utilize magnetic therapeutic effects such as promoting blood circulation and improving metabolism. The position where the treatment device 1 is attached is not particularly limited, and may be any position such as the skin of the shoulder or the waist as long as the magnetic treatment effect can be utilized.

As shown in FIG. 1, the treatment device 1 has a container 2 having an internal space 21 and a bottom surface 24, a magnet portion 3 rotatably housed in the internal space 21, and a direction substantially perpendicular to the bottom surface 24. It is provided with a rotation drive mechanism 4 that rotationally drives the magnet portion 3 in a plane substantially parallel to the bottom surface 24 about the rotation axis X extending to the center. The treatment device 1 is varied in a wide range even when the user does not move because the magnet portion 3 is rotationally driven by the rotation 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 portion 3 in the internal space 21, and when the treatment device 1 is attached to the user's skin S, directly or indirectly to the skin S. It is a member that comes into contact. In the present embodiment, as shown in FIGS. 1 to 3, the container 2 is formed in a substantially columnar shape as a whole, and surrounds the internal space 21, the upper surface 22, the side surface 23, and the treatment device 1 are the skin S. It has a bottom surface 24 that comes into direct or indirect contact with the skin S when attached to. However, the container 2 may have an internal space 21 having a size capable of rotatably accommodating the magnet portion 3, and may have a bottom surface 24 that directly or indirectly contacts the skin S. It may have other shapes such as a prismatic shape or a substantially conical shape.

The treatment device 1 can be attached to the user's skin S so that the bottom surface 24 comes into direct contact with the skin S, for example, by an adhesive tape provided so as to cover from above or an attachment means such as a band. For example, an adhesive sheet may be provided between the bottom surface 24 and the skin S, and the bottom surface 24 may be attached to the user's skin S so as to indirectly contact the skin S. As described above, the treatment device 1 may be attached to the skin S so that the bottom surface 24 of the container 2 comes into direct or indirect contact with the skin S, and the attachment method is not particularly limited, but the magnet portion 3 described later is not limited. In order to maximize the magnetic therapeutic effect of the above, it is preferable that the bottom surface 24 is attached to the skin S so as to be 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 an external force, and the magnetic flux lines generated by the magnet portion 3 can be easily transmitted (the magnetic field generated by the magnet portion 3). The material may be any material that does not shield the material, and is not particularly limited. For example, acrylonitrile butadiene styrene (ABS), polycarbonate acrylonitrile butadiene styrene (PC-ABS), polyethylene (PE), or polyethylene terephthalate (PET). Synthetic resin materials such as the above can be preferably used. In particular, since the strength of the magnetic field rapidly attenuates as the distance from the magnet portion 3 increases, the magnet portion 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 fluctuating magnetic field by being rotated by a rotation drive mechanism 4 in the internal space 21 of the container 2 rotatably housed. In the present specification, the term "fluctuation magnetic field" means a magnetic field in which the direction and intensity of the magnetic field fluctuate. In the treatment device 1, the magnet portion 3 is rotated by the rotation drive mechanism 4 to generate a fluctuating magnetic field, thereby giving a large stimulus to the skin S surface and the blood vessels and tissues in the body near the skin S surface, resulting in high magnetism. It can exert a therapeutic effect. The configuration of the magnet portion 3 is not particularly limited as long as it is rotatably housed in the internal space 21 of the container 2 and can be rotated by the rotation drive mechanism 4 to generate a fluctuating magnetic field. A suitable configuration as described can be adopted.

The magnet portion 3 of the treatment device 1 according to the present embodiment will be described with reference to FIGS. 4 (a), 4 (b) and 5. The magnet portion 3 includes a magnetic shield portion 31 and magnets 32a and 32b, and the magnetic shield portion 31 has a magnetic field generated by the magnets 32a and 32b on the side opposite to the bottom surface 24 of the container 2 (in FIG. 4A). It is configured to block leakage to the back side of the paper surface, the upper middle side of FIG. 4B, and the upper middle side of FIG. More specifically, as shown in FIG. 5, the magnet portion 3 has a direction in which the magnetic flux lines M generated by the magnets 32a and 32b face the side opposite to the bottom surface 24 of the container 2, and the magnet portion 3 The direction in which the magnetic flux line M extends in the radial direction inward and outward directions of the rotating orbit is changed by the magnetic shield portion 31 so as to face the bottom surface 24 side of the container 2. Therefore, the treatment device 1 can avoid the magnetic field leakage to the upper side opposite to the skin S, that is, in the 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 affected by the leakage magnetic field and damage the magnetic card when using the treatment device 1. You may come across situations 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. Further, since the magnet portion 3 is configured so that the magnetic field does not leak in a direction other than the bottom surface 24 side of the container 2, it is possible to prevent the magnetic field from leaking to the rotation drive mechanism 4 and the electronic substrate 6 described later, and these portions. Malfunctions and wasteful energy consumption due to the magnetic field of the magnet are avoided. Further, the magnetic flux lines M generated by the magnets 32a and 32b are concentrated in the direction toward the bottom surface 24 side of the container 2, so that they are concentrated in the skin S surface below the magnet portion 3 and in the body near the skin S surface. A magnetic field can be applied to the magnet, and even if the magnets 32a and 32b are made small, a larger magnetic therapeutic effect can be obtained.

The magnetic shield portion 31 contains a material capable of shielding the magnetic field, and shields 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. In the present embodiment, as shown in FIGS. 4A and 4B, the magnetic shield portion 31 has a substantially U-shaped cross section substantially perpendicular to the rotation direction of the magnet portion 3, and the magnet portion as a whole has a magnet portion. It is formed in a substantially annular shape extending along the rotation direction of 3. More specifically, the magnetic shield portion 31 has a magnet holding portion 31a formed in a substantially annular flat plate shape and a skin S side (bottom surface 24 side of the container 2) from the outer outer circumference of the magnet holding portion 31a in the radial direction. It is provided with an outer peripheral portion 31b extending inward and an inner peripheral portion 31c extending from the inner circumference of the magnet holding portion 31a in the radial direction to the skin S side (bottom surface 24 side of the container 2). The magnetic shield portion 31 is fixed to the inner peripheral portion 31c, and is fixed to the shaft X1 in a relative non-rotatable manner by a fixing portion 34 provided with a hole H into which the shaft X1 (see FIG. 1) can be inserted. In the present embodiment, the magnets 32a and 32b are provided on the skin S side of the magnet holding portion 31a of the magnetic shield portion 31 between the outer peripheral portion 31b and the inner peripheral portion 31c of the magnetic shield portion 31, and the magnets 32a, The direction of the magnetic flux line M generated from the 32b is changed to prevent the magnetic field generated by the magnets 32a and 32b from leaking to the upper side and the radial outer side and the inner side of the magnetic shield portion 31. However, the magnetic shield portion 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), and has a shape thereof. Is not particularly limited, and can be appropriately changed according to the shapes of the magnets 32a and 32b.

The material contained in the magnetic shield portion 31 capable of shielding the magnetic field is not particularly limited, but a high magnetic permeability material can be used, and for example, permalloy, pure iron, silicon steel, or the like can be used. Can be done. Among them, permalloy having excellent coercive force is preferable, and Mo-based permalloy having more excellent coercive force is more preferable.

In the present embodiment, as shown in FIGS. 4 (a) and 4 (b), the magnet portions 3 have a plurality of magnetic pole directions extending substantially perpendicular to the bottom surface 24 of the container 2, respectively (in the present embodiment). The magnets 32a and 32b of (2) are provided. Then, each of the plurality of magnets 32a and 32b is arranged apart from each other along the rotation direction of the magnet portion 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 portion 3 They have magnetic pole directions that face substantially opposite directions. In the present embodiment, the magnet 32a is magnetized so that the lower side is the north pole and the upper side is the south pole (so that the magnetic pole direction faces the upper side), and the magnet 32b has the lower side the south pole and the upper side the north pole. It is magnetized so that (the magnetic pole direction faces downward). The magnet unit 3 is provided with a plurality of magnets 32a and 32b, each of which is separated from each other and has magnetic pole directions facing substantially opposite directions, thereby generating an alternating magnetic field by the rotation of the magnet unit 3. The magnet portion 3 is provided with a plurality of magnets 32a and 32b whose 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 portion 3 is rotated has the magnetic pole directions facing 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. Further, the magnetic pole directions of the magnets 32a and 32b used extend substantially perpendicular to the bottom surface 24 (and the skin S surface) of the container 2, so that the magnetic pole directions extend substantially parallel to the bottom surface 24 (and the skin S surface). Compared with the case of using a magnet, the magnetic field strength in a direction substantially perpendicular to the skin S surface becomes larger, and magnetism acts from the skin S surface to a deeper body. Further, since the magnets 32a and 32b are separated from each other along the rotation direction of the magnet portion 3, when the magnet portion 3 rotates, the skin S surface and the blood vessels and internal tissues near the skin S surface feel a magnetic field. It is possible to secure a time when there is no time, that is, a time for relaxation without being affected by the magnetic field. Therefore, since the blood vessels and internal tissues on the skin S surface and in the vicinity of the skin S surface can alternately repeat relaxation and tension more reliably, the treatment device 1 can be used in the skin S surface and in the vicinity of the skin S surface. It can give a great stimulation to the tissue and exert a high magnetic therapeutic effect.

In the present embodiment, the magnets 32a and 32b of the magnet portion 3 generate magnetic fields of substantially the same size and facing opposite directions at the same location on the skin S when the magnet portion 3 rotates. It is configured. As shown in FIGS. 4A and 4B, the magnets 32a and 32b are both formed in a substantially annular shape extending along the rotation direction of the magnet portion 3, and both are formed to have the same size. .. More specifically, the magnets 32a and 32b are formed in a substantially annular shape in which the magnets 32a and 32b each extend by about 1/4 circumference along the rotation direction of the magnet portion 3 and the inner circumference diameter thereof is approximately half or more of the outer circumference diameter. There is. In other words, the magnets 32a and 32b are formed in an arc-shaped band shape with the radial inside of the fan shape removed, and are arranged so as to form a substantially annular locus when the magnet portion 3 rotates. The magnet portion 3 can be formed so that the magnets 32a and 32b are formed in a substantially annular shape (belt shape) so that the magnet portion 3 has a larger diameter than the case where a magnet formed in a fan shape in the same amount is used. It is possible to apply a magnetic force to more blood vessels near the surface of the skin S. Since the rare earth magnet that can generate 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 (belt shape) as in the present embodiment. A magnetic force can be applied to more blood vessels even by volume, and a larger magnetic therapeutic effect can be obtained. Further, since the weight of the magnet portion 3 can be reduced, the torque received from the magnet portion 3 by the rotation drive mechanism 4 can be reduced, and the rotation 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 pass through two cavities 33a and 33b having substantially the same shape and size as the two magnets 32a and 32b. The magnet portions 3 are arranged apart from each other in the rotation direction. When the magnet portion 3 having such an arrangement rotates at a constant speed, the magnet portion 3 passes through the skin S surface in the order of the magnet 32a, the cavity 33a, the magnet 32b, and the cavity 33b (or vice versa). An alternating magnetic field having a single frequency is generated with respect to the skin S surface. By generating an alternating magnetic field having a single frequency, the treatment device 1 can expose the alternating magnetic field having a single frequency to the skin S surface of the user and the tissues in the body near the skin S surface. It can also stimulate cells in tissues to have the effect of healing cell dysfunction such as inflammation.

In the magnet portion 3 of the present embodiment, two magnets 32a and 32b are provided, but if the magnet portion 3 can generate the alternating magnetic field having a single frequency described above, the number of magnets is one. It may be three or more. At this time, the magnet portion 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 portion 3, so that the magnet portion 3 has the same shape. A single frequency alternating magnetic field can be generated by rotation.

The materials of the magnets 32a and 32b are not particularly limited, and for example, neodymium, ferrite, samarium cobalt, artificial magnetic material and the like can be adopted. However, it is desirable that the output level is within the range of the certification standard of the Ministry of Health, Labor and Welfare.

With reference to FIGS. 1 to 3 again, the rotation drive mechanism 4 has an electric drive source 41 that generates a rotation drive force centered on a rotation axis Y extending substantially perpendicular to the bottom surface 24, and a magnet portion for the rotation drive force. It is provided with a rotational driving force transmission mechanism 42 that transmits to 3. The electric drive source 41 is provided apart from the magnet portion 3 in a plane substantially parallel to the bottom surface 24. That is, the electric drive source 41 is arranged so as not to overlap the magnet portion 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 fluctuating magnetic field generated from the magnet portion 3 toward the skin S side can be suppressed to a small extent. However, the rotation drive mechanism 4 is not limited to the above-described configuration as long as the magnet portion 3 can be rotated in a plane substantially parallel to the bottom surface 24 of the container 2. For example, the electric drive source 41 may be used. It may be arranged so as to overlap the magnet portion 3 along a direction substantially perpendicular to the bottom surface 24 and may be directly connected to the magnet portion 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 the electronic board 6 electrically connected to the power supply unit 5, and is electrically connected to the electronic board 6 from the power supply unit 5. Electric power is supplied through No. 6 to generate a rotational driving force centered on the rotational 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 the present embodiment, the power supply unit 5 is non-removably fixed to the container 2. The power supply unit 5 may be a replaceable battery, but by being non-removably fixed to the container 2, it is possible to prevent an accident such as a child accidentally swallowing the battery. 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, for example, other than during normal use. It does not mean that it cannot be removed until it needs to be removed for overhaul. In the present embodiment, the power supply unit 5 is a secondary battery that can be charged via the USB terminal 7. Therefore, since the power supply unit 5 can be easily charged, the treatment device 1 can be easily carried and carried. Further, since the power supply unit 5 can be used repeatedly, it is possible to save the trouble of replacing the battery as in the case of a non-rechargeable battery.

In the present embodiment, the rotational driving force transmission mechanism 42 is configured to reduce the rotation 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, as shown in FIGS. 1 and 2, the rotational driving force transmission mechanism 42 is fixed to the shaft Y1 extending from the electric drive source 41 along the rotation axis Y so as to be relatively non-rotatable. The second gear 42b, which meshes with the first gear 42a, has a larger diameter and has more teeth than the first gear 42a, and is fixed to a shaft X1 extending from the magnet portion 3 along the rotation axis X so as to be relatively non-rotatable. And have. 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 about the rotation shaft Y, and the second gear 42b that meshes with the first gear 42a accordingly. It rotates around the rotation axis X together with the shaft X1, and the magnet portion 3 fixed to the shaft X1 so as not to rotate relative to the shaft X1 rotates around 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 rotation speed of the electric drive source 41 is decelerated and the magnet portion 3 is rotated, so that the magnet portion 3 is slowed down. It can be rotated by rotation. Further, even if the weight of the magnet portion 3 is increased, the torque received by the electric drive source 41 from the magnet portion 3 can be reduced.

The treatment device 1 is further electrically connected to the electronic board 6 as shown in FIGS. 1 and 2, and lights up when the power supply unit 5 is in the charging state, and the charging of the power supply unit 5 is completed. It is provided with an LED lamp 8 configured to turn off the light. Therefore, in the treatment device 1, it is possible to easily determine whether the power supply unit 5 is in the charged state and whether the power supply unit 5 has completed charging, so that the charging operation becomes easy and the charge runs out during use. It becomes easier to avoid such a situation. Further, the treatment device 1 is further electrically connected to the electronic substrate 6 and includes a switch 9 for turning on / off the electric drive source 41. In the treatment device 1, when the user turns on the switch 9, the magnet portion 3 starts to rotate, resulting in a magnetic treatment effect.
