Magnetic therapy device

The present invention relates to a magnetic treatment device that is used on a neck or arm and is expected to have an effect of promoting blood circulation by the action of magnetism.

It is known that wearing a necklace or bracelet with a magnet can provide effects such as blood circulation promotion by the action of magnetism. For example, a magnetic treatment device such as a necklace in which a magnet is embedded in a flexible ring-shaped support member has been proposed.

In a conventional magnetic therapy device, magnets are arranged in a ring-shaped support member at almost equal intervals. As for the direction of the magnetic pole, the magnets that are symmetric with respect to the center of the ring are arranged so that the direction of the magnetic pole is the target, or the inner diameter side is all S poles (or N poles). What to place has been proposed.

However, the conventional magnetic therapy device has a problem that the magnetic flux generated by the magnet is distributed only in a narrow area around the magnet, and it is difficult to cause sufficient magnetism to act on the treatment site away from the magnet.

This invention is made in view of such a situation, and is providing the magnetic treatment tool which can make magnetism act also on the treatment location away from the magnet.

In order to achieve the above object, a magnetic therapy device according to the present invention comprises:
A plurality of magnet arrangement portions arranged along a circumferential direction surrounding the ring center position;
A plurality of magnet arrangement parts connected to each other to form a ring shape,
Each of the magnet arrangement portions includes a plurality of magnets arranged along the circumferential direction,
The plurality of magnets included in the same magnet arrangement portion are arranged such that the magnetic pole directions are all directions intersecting the circumferential direction and the same poles face the same side,
The angle seen from the ring center position between two magnets adjacent to each other and included in the same magnet arrangement part is θ, and the angle seen from the ring center position between two magnet arrangement parts adjacent to each other Is δ, and the number of the magnets included in the same magnet arrangement part is n,
θ <δ / n.

The magnetic treatment device according to the present invention does not arrange magnets at equal intervals in the circumferential direction, but arranges a group of magnets included in the same magnet arrangement portion at a narrow interval and with the magnetic poles aligned in the same direction. Thus, the magnetic flux can be applied to the treatment site away from the magnet. Moreover, it can prevent that the number of the magnets contained in a magnetic treatment tool increases too much by expanding the space | interval of one magnet arrangement | positioning part and another one magnet arrangement | positioning part more than predetermined.

Also, for example, δ ≧ 2 × n × θ may be sufficient for the magnetic treatment device according to the present invention.

In such a magnetic treatment device, the interval between the magnets included in the same magnet arrangement portion becomes smaller than the interval between the magnet arrangement portions, so that the magnetic flux acts more effectively at a position away from the magnet. Can do. In addition, since such a magnetic treatment device has a wide interval between the magnet arrangement portions, it can have higher flexibility and is advantageous in terms of weight reduction.

Also, for example, the magnetic treatment device according to the present invention may have θ ≦ 10 °.

The value of θ that defines the interval between the magnets included in the same magnet arrangement portion can be appropriately set according to the size of the magnetic therapy device, the magnetic force of the magnet included in the magnetic therapy device, etc. ≦ 10 ° is preferable from the viewpoint of more effectively acting the magnetic flux at a position away from the magnet.

Further, for example, the connection portion may have a first joint end portion and a second joint end portion that can be joined and separated from each other,
The magnet arrangement part and the connection part may form the ring shape by joining the first joint end part and the second joint end part to each other.

A magnetic treatment device having a first joint end and a second joint end as a connecting portion can be easily worn and removed, and can be worn on a place such as a neck or an arm. Thus, it can have a more suitable circumference.

Further, for example, in the cross section orthogonal to the circumferential direction of the connection portion, a first length that is a radial length from the ring center position toward the connection portion is orthogonal to the circumferential direction and the radial direction. It may be shorter than the second length which is the length in the axial direction.

When such a magnetic treatment device is attached to the neck, for example, the inner side of the magnetic treatment device is easily directed toward the neck. The effect of magnetic flux can be enhanced.

First Embodiment FIG. 1 is a conceptual diagram showing the arrangement of magnets 30 in a magnetic treatment device 10 according to a first embodiment of the present invention, and FIG. 2 is an external view of the magnetic treatment device 10. The magnetic treatment device 10 has a ring-shaped outer shape, and promotes blood circulation around the magnetic treatment device 10 by being hung on the neck like a necklace or on the arm like a bracelet. It is.

The size of the magnetic therapy device 10 is not particularly limited. For example, a device used as a necklace has a peripheral length of about 30 to 70 cm in the circumferential direction 14, and a device used as a bracelet has a peripheral length of about 30 to 70 cm. It is about 10 to 30 cm.

As shown in FIG. 1, the magnetic treatment device 10 includes a plurality (eight in the first embodiment) of magnet arrangement portions 20 arranged along the circumferential direction 14 surrounding the ring center position 12 and a plurality of magnet arrangement portions. 20 and a connecting portion 40 that forms a ring shape.

Each magnet arrangement portion 20 includes a plurality (two in the first embodiment) of magnets 30 arranged along the circumferential direction 14. The magnetic therapy device 10 has eight magnet arrangement portions 20 each having two magnets 30, and therefore has a total of 16 magnets 30. However, the number of magnets 30 included in the magnetic therapy device 10 is not limited as long as a mathematical formula (1) relationship described later is satisfied.

The two magnets 30 included in the same magnet arrangement unit 20 are arranged such that the magnetic pole directions are both directions intersecting the circumferential direction 14 and the same poles face the same side. As shown in FIG. 1, in the magnet placement portion 20 of the magnetic treatment device 10, the magnetic pole direction of the magnet 30 faces the radial direction that is perpendicular to the circumferential direction 14, and the N poles of the two magnets 30 are both It is arranged so that the inner diameter side faces and the S poles of the two magnets 30 both face the outer diameter side.

Here, as shown in FIG. 1, the magnetic treatment device 10 is included in the same magnet arrangement portion 20 and is adjacent to each other, where θ is an angle viewed from the ring center position 12 between two adjacent magnets 30. When the angle seen from the ring center position 12 between the two magnet arrangement parts 20 is δ and the number of magnets 30 included in the same magnet arrangement part 20 is n, the following Expression 1 is satisfied.

Θ <δ / n (Formula 1)

When the arrangement of the magnets 30 included in the magnetic therapy device 10 satisfies the relationship of Equation 1, the magnets 30 included in the magnetic therapy device 10 are not evenly arranged along the circumferential direction 14. Furthermore, when paying attention to an arbitrary magnet 30 in the magnetic therapy device 10, a certain magnet 30 (for example, M <b> 1 in FIG. 1) is placed in the same magnet arrangement unit 20 than any magnet 30 included in the other magnet arrangement unit 20. It will be in the state arrange | positioned adjacent to the other magnet 30 (M2 of FIG. 1) which is contained and adjoins.

Further, as shown in FIG. 1, since the magnets 30 included in the same magnet arrangement part 20 are all arranged so that the same pole faces the same side, the magnetic treatment device 10 has the same magnetic pole direction. The magnets 30 arranged are arranged close to each other. Thereby, in the magnetic therapy tool 10, it becomes possible to exert a magnetic flux to the position away from the magnet 30, and it becomes possible to make magnetic force act also on the treatment location away from the magnet 30. Moreover, since the space | interval (magnitude | size of (delta)) between the magnet arrangement | positioning parts 20 becomes large by satisfy | filling the relationship of Numerical formula 1, it prevents that the number (total number) of the magnets 30 contained in a magnetic treatment tool increases too much. This contributes to weight reduction of the magnetic therapy device 10.

The angle θ is appropriately set according to the size and material of the magnet 30, the residual magnetic flux density, etc., for example, preferably 10 ° or less, and more preferably 6 ° or less. By reducing the angle θ, the magnetic flux can be applied to a position further away from the magnet 30. The angle θ is defined by an angle formed by a line connecting the center of the magnet 30 and the ring center position 12, as shown in FIG. Further, the angle θ in the magnetic therapy device 10 is 4 °.

The angle δ is appropriately set according to the circumference of the magnetic treatment device 10, the size and material of the magnet 30, the residual magnetic flux density, etc., but is preferably 20 to 120 °, for example, 30 to 90 °. More preferably. By making the angle δ greater than or equal to a predetermined value, the number of magnets 30 used in the magnetic therapy device 10 can be reduced to reduce the weight of the magnetic therapy device 10, and by making the angle δ less than or equal to a predetermined value, magnetic therapy can be performed. By increasing the number of magnets 30 used in the tool 10, the range covered by the strong magnetic flux can be expanded. As shown in FIG. 1, the angle δ is defined by an angle formed by a line connecting the center of the magnet placement portion 20 and the ring center position 12. Further, the angle δ in the magnetic therapy device 10 is 45 °.

Further, the magnetic therapy device 10 shown in FIG. 1 satisfies the following mathematical formula 2 in addition to the mathematical formula 1 described above.

Δ ≧ 2 × n × θ (Formula 2)

Since the magnetic treatment device 10 satisfying the relationship of the mathematical formula 2 has a smaller interval (angle θ) between the magnets included in the same magnet arrangement unit 20 than the interval (angle δ) between the magnet arrangement units 20, The magnetic flux can be effectively applied to a position away from the magnet 30. In addition, since the magnetic treatment device 10 has a wide interval (angle δ) between the magnet arrangement portions 20, it can have higher flexibility and is advantageous in terms of weight reduction. Even when the magnetic treatment device 10 can be flexibly deformed into a shape other than a circle, the ring center position 12 is arranged so that the magnetic treatment device 10 is in a ring shape that is in use, and a circle defined by the ring. (Or is defined by the center of the arc (see FIG. 13) that forms part of the ring).

The connecting portion 40 of the magnetic treatment device 10 is preferably flexible depending on the material itself or the structure, and the material is not particularly limited. For example, a molding resin material such as silicon rubber or urethane rubber, or a belt-like shape is used. Alternatively, a string-like fiber material, a metal material connected like a chain, or a combination thereof can be used. Moreover, although the cross-sectional shape of the magnet arrangement | positioning part 20 and the connection part 40 shown in FIG. 2 is circular, the cross-sectional shape of the magnet arrangement | positioning part 20 and the connection part 40 is not limited to this, Other than circular, such as an ellipse, trapezoid, and a rectangle The shape may also be Furthermore, the cross-sectional shape of the magnet arrangement | positioning part 20 and the connection part 40 may be changing with the position of the circumferential direction 14, and the magnetic treatment tool 10 may have the outer shape which has undulations on the surface.

Further, the cross-sectional shape of the connection portion 40 may be the same as the cross-sectional shape of the magnet arrangement portion 20, but the cross-section and appearance shape of the magnet arrangement portion 20 and the connection portion 40 may be different. For example, the magnet arrangement | positioning part 20 may have a bulge in the part in which the magnet 30 is located.

2 can be manufactured, for example, by integrally molding the magnet arrangement portion 20 excluding the magnet 30 and the connection portion 40 with silicon rubber. As shown in FIG. 1, such a magnetic therapy device 10 can be manufactured by molding silicon rubber so that a magnet 30 is embedded in a predetermined position. In this case, the magnet 30 may be magnetized before being embedded in the silicone rubber or after being embedded in the silicone rubber.

The magnetic treatment device 810 according to the ninth embodiment has four magnet arrangement portions 20 and one magnet arrangement portion 820, and is the first embodiment in that the largest angle δ (δ7) is 180 °. It differs from the magnetic therapy tool 10 which concerns on a form. However, since the magnetic treatment device 810 is the same as the magnetic treatment device 10 in other points, only the differences from the magnetic treatment device 10 will be described in the description of the magnetic treatment device 810, and the common parts will be described.

As shown in FIG. 12, the magnet arrangement unit 20 includes two magnets 30, whereas the magnet arrangement unit 820 includes three magnets 30. The three magnets 30 included in the magnet arrangement unit 820 are similar to the two magnets 30 included in the magnet arrangement unit 20, so that the N poles of the three magnets 30 face the inner diameter side, and the S poles of the three magnets 430. Are arranged so as to face the outer diameter side.

The angle θ viewed from the ring center position 12 between the two magnets 30 that are included in the magnet arrangement part 820 and are adjacent to each other is the same as that of the magnet arrangement part 20. The magnet arrangement part 820 and the magnet arrangement part 20 are adjacent to each other, and the angle δ (δ6) viewed from the ring center position 12 between the magnet arrangement part 820 and the magnet arrangement part 20 is an expression in relation to the angle θ. 1 and Formula 2 are satisfied.

The arrangement and the like are the same as those of the magnetic therapy device 810. Therefore, in the description of the magnetic treatment device 910, only differences from the magnetic treatment device 810 will be described, and description of common parts will be omitted.

The magnetic treatment device 910 has a flexible arc-shaped portion 942 connected to the magnet arrangement portion, and an L-shaped portion 943 that connects both ends of the arc-shaped portion 942. The arc-shaped portion 942 is made of a flexible material such as silicon, while the L-shaped portion 943 is made of a resin or metal harder than the material forming the arc-shaped portion 942.

Unlike the magnetic treatment device 810 shown in FIG. 12, the magnetic treatment device 910 shown in FIG. 13 does not have a circular ring. However, the magnetic treatment device 910 is similar to the magnetic treatment device 810 shown in FIG. Formula 2 is satisfied, and the same effect as the magnetic treatment device 810 is achieved. Even when the ring is not circular as in the case of the magnetic treatment device 910, the ring center position 812 is defined by the center of a circle including the arc of the arc-shaped portion 942.

As mentioned above, although the present invention has been described with reference to the embodiments, it is needless to say that the present invention is not limited to these embodiments, and has many other embodiments and modifications. For example, in the first embodiment shown in FIG. 1, the magnetization direction of the magnet 30 is the radial direction of the ring, but the magnetization direction of the magnet 30 may be another direction that intersects the circumferential direction. The magnetization direction may be the axial direction of the ring.

Moreover, as shown in FIG.11 (b), although the cross section of the magnet arrangement | positioning part 720 and the connection part 740 which concern on 8th Embodiment is longer than the radial direction 16 side on the axial direction 15 side, on the contrary, other The magnet arrangement | positioning part and connection part of embodiment may have a cross section where the radial direction 16 side is longer than the axial direction 15 side. In such an embodiment, in the cross section orthogonal to the circumferential direction of the magnet arrangement portion, the first length that is the radial length from the ring center position 12 toward the magnet arrangement portion is in the circumferential direction 14 and the radial direction 16. It is longer than the second length which is the length of the axial direction 15 perpendicular to the axis.

In such a magnetic treatment device according to another embodiment, for example, when it is hung on the neck, the adhesion to the base portion of the neck such as the periphery of the collarbone is improved. The effect can be enhanced. Further, in this case, by setting the magnetization direction of the magnet included in the magnetic treatment tool as the axial direction, the magnetic flux of the magnet easily reaches the treatment site such as the base of the neck and the shoulder.

In the magnetic therapy device according to Comparative Example 2, the magnet 30 with the north pole facing the inner diameter side and the magnet 430 with a different magnetic pole direction from the magnet 30 and the south pole facing the inner diameter side are adjacent to each other in the same magnet arrangement portion 920. Are arranged as follows. The magnet 30 included in the magnetic therapy device according to the comparative example 3 is the same as that of the first embodiment, and the magnet 430 is the same as the magnet 30 except that the direction of the magnetic pole is opposite to the ring center position 12. is there. Further, the magnets 30 and 430 were arranged on the circumference of a circle having a diameter of 170 mm centered on the ring center position 12 as in the first embodiment. The calculation results are shown in FIG.

Comparative Example 3
FIG. 14 (d) is a conceptual diagram showing the arrangement of the magnets 30 in the magnetic therapy device according to Comparative Example 3. In the magnetic therapy device according to Comparative Example 3, the same number (16 in total) of magnets 30 and 430 as in Example 1 were arranged at equal intervals along the circumferential direction 14 surrounding the ring center position 12. In the magnetic therapy device according to Comparative Example 3, the magnet 30 with the north pole facing the inner diameter side and the magnet 430 with the south pole facing the inner diameter side were alternately arranged along the circumferential direction 14. The angle θ viewed from the ring center position 12 between the two adjacent magnets 30 and 430 is 22.5 °. The magnet 30 included in the magnetic therapy device according to the comparative example 3 is the same as that of the first embodiment, and the magnet 430 is the same as the magnet 30 except that the direction of the magnetic pole is opposite to the ring center position 12. is there. Further, the magnets 30 and 430 were arranged on the circumference of a circle having a diameter of 170 mm centered on the ring center position 12 as in the first embodiment. The calculation results are shown in FIG.

FIG. 15 is a graph showing the calculation results regarding the relationship between the radial distance r (see FIG. 1) from the magnet and the maximum value B of the magnetic flux density for the magnetic therapy device shown in FIGS. 14 (a) to 14 (b). It is a thing. The solid line (a) in FIG. 15 represents the calculation result of the magnetic therapy device according to Example 1, and the broken line (b) in FIG. 15 represents the calculation result of the magnetic therapy device according to Comparative Example 1. A one-dot chain line (c) in FIG. 15 represents the calculation result of the magnetic therapy device according to Comparative Example 2, and a two-dot chain line (d) in FIG. 15 represents the calculation result of the magnetic therapy device according to Comparative Example 3. Represents.

As can be understood from FIG. 15, the magnetic treatment device according to Example 1 indicated by the solid line (a) has a higher density than the magnetic treatment devices according to Comparative Examples 1 to 3 to a position further away from the magnet. It can be understood that the magnetic flux is reaching. For example, taking the position of 10 mm from the magnet as an example, the magnetic flux of 0.935 mT is exerted in Example 1 indicated by the solid line (a), whereas in Comparative Examples 1 to 3, compared to Example 1. It can be understood that the magnetic flux density is reduced by about 40 to 60% (Comparative Example 1 (0.545 mT), Comparative Example 2 (0.382 mT), and Comparative Example 3 (0.577 mT)).

FIG. 16 is a conceptual diagram for explaining that the difference as shown in FIG. 15 occurs in the magnetic flux distribution state in the magnetic therapy device according to Example 1 and Comparative Examples 1 to 3. FIG. 16A is a conceptual diagram showing the state of magnetic flux lines distributed around the magnets 30 and 430 in the magnetic therapy device in which the magnets 30 and 430 are evenly arranged as in Comparative Example 1 and Comparative Example 3. . In the magnetic therapy device according to Comparative Example 1 and Comparative Example 3 in which the magnets 30 and 430 are evenly arranged, as shown by a broken line in FIG. 16A, no other magnets are arranged nearby. In the vicinity of 30 and 430, a magnetic circuit is formed in which magnetic flux is emitted from the N pole of the magnet, returns to the S pole of the same magnet, and the magnetic flux concentrates in a region near the magnets 30 and 430. Therefore, the magnetic flux of the magnets 30 and 430 does not extend far from the magnet 30.

FIG. 16B illustrates a magnetic treatment device in which two magnets 30 and 430 having different poles facing the same side are arranged adjacent to each other in the same magnet arrangement portion 920 as in Comparative Example 2. 430 is a conceptual diagram illustrating a state of magnetic flux lines distributed around 430. FIG. In the magnetic therapy device according to Comparative Example 2 in which two magnets 30 and 430 having different poles facing the same side are arranged close to each other as represented by a broken line in FIG. Since the S pole of the other magnet is arranged close to the magnetic pole, the magnetic flux emitted from the N pole of the magnets 30 and 430 returns to the S pole of the other adjacent magnet or the S pole of the same magnet. Therefore, in the magnetic therapy device according to Comparative Example 2, a magnetic circuit in which magnetic flux concentrates in a region near the magnets 30 and 430 is formed. Therefore, the magnetic flux of the magnets 30 and 430 does not extend far from the magnet 30.

FIG. 16C shows a magnetic treatment device in which two magnets 30 with the same pole facing the same side are arranged adjacent to each other in the same magnet arrangement part 20 as in the first embodiment. It is a conceptual diagram showing the state of the distributed magnetic flux line. In the magnetic therapy device according to the first embodiment in which two magnets 30 and 430 having the same pole facing the same side are arranged close to each other as represented by a broken line in FIG. (Or S pole) and the N pole (or S pole) of the other magnet 30 are arranged close to each other, so that the magnetic flux emitted from the N pole of the magnet 30 is influenced by the N pole of the other adjacent magnet. This prevents the return to the south pole through the region close to the magnet 30. Therefore, in the magnetic therapy device according to the first embodiment, a magnetic circuit that extends the magnetic flux to a region far from the magnet 30 is formed. Therefore, the magnetic therapy device according to the first embodiment can deliver magnetism to a position far away from the magnet 30.

From the results of Example 1 and Comparative Examples 1 to 3 shown in FIGS. 14 to 16, the two magnets 30 having the same poles facing the same side as in Example 1 are adjacent to each other in the same magnet arrangement portion 20. It can be understood that the magnetic treatment device arranged can deliver magnetism not only to the vicinity of the surface near the magnet 30 but also to a deeper treatment site. The magnetic treatment device according to Example 1 can be expected to improve the treatment effect for a deep treatment site.

Example 2 and Comparative Example 4
FIGS. 17 and 18 illustrate the distribution state of the magnetic therapy device according to the second embodiment, in which the distribution of magnetic flux lines formed around the magnetic therapy device is calculated by the finite element method. Similarly to the magnetic treatment device shown in FIG. 14A, the magnetic treatment device according to the second embodiment has a plurality of magnet arrangement portions 20 arranged along the circumferential direction 14 surrounding the ring center position 12. The magnet arrangement unit 20 includes two magnets 30. The magnetic pole direction of the magnet 30 is aligned so that the N pole faces the inner diameter side and the S pole faces the outer diameter side. The angle θ viewed from the ring center position 12 between two adjacent magnets 30 in the same magnet arrangement portion 20 is 4 °. The magnet 30 included in the magnetic treatment device according to the second embodiment is the same as that of the first embodiment, but the magnetic treatment device according to the second embodiment is viewed from the ring center position 12 between two adjacent magnet arrangement portions 20. The angle δ is 30 °, and 12 magnet arrangement portions 20 are included.

FIG. 17 is a diagram observing magnetic flux lines formed around the magnetic treatment device according to the second embodiment from the axial direction, and FIG. 18 is formed around the magnetic treatment device according to the second embodiment from an oblique direction. FIG.

19 and 20 illustrate the distribution state of the magnetic treatment device according to Comparative Example 4 by calculating the distribution of magnetic flux lines formed around the magnetic treatment device by the finite element method. The magnetic therapy device according to Comparative Example 4 has a magnet at the same position as the position where the magnet 30 is arranged in Example 2, as in the relationship of Comparative Example 2 (see FIG. 14C) with respect to Example 1. 30 or magnet 430 was placed. In the magnetic therapy device according to Comparative Example 4, the magnet 30 with the north pole facing the inner diameter side and the magnet 430 with a different magnetic pole direction from the magnet 30 and the south pole facing the inner diameter side are adjacent to each other in the same magnet arrangement portion 920. Arranged. The magnets 30 and 430 included in the magnetic therapy device according to the comparative example 4 are the same as those in the comparative example 2.

FIG. 19 is a diagram observing magnetic flux lines formed around the magnetic treatment device according to Comparative Example 4 from the axial direction, and FIG. 20 is formed around the magnetic treatment device according to Comparative Example 4 from the oblique direction. FIG.

As can be understood from the results of Example 2 shown in FIGS. 17 and 18 and the results of Comparative Example 4 shown in FIGS. 19 and 20, two magnets 30 having the same poles facing the same side as in Example 2 are the same. In the magnetic therapy device arranged so as to be adjacent to each other in the magnet arrangement unit 20, the magnetic flux lines are spread farther away from the magnetic therapy device than in the comparative example 4, and the distribution of the magnetic flux lines is the comparative example 4. It can be understood that it is three-dimensional. Therefore, in the magnetic therapy device according to the second embodiment, improvement of the therapeutic effect can be expected not only in a narrow region near the magnetic therapy device but also in a wide range away from the magnetic therapy device.

Example 3
In Example 3, with respect to a magnetic therapy device having the same kind of magnet arrangement as that of the magnetic therapy device according to Example 1 as shown in FIG. When the magnetic flux density B is changed, how the magnetic flux density B changes at a position away from the magnet 30 in the inner diameter direction by a predetermined distance (7.5 mm) was calculated. The used magnet 30 and the arrangement of the magnet arrangement unit 20 are the same as those in the first embodiment. The calculation results are shown in FIG.

21, it can be understood that a strong magnetic flux can be exerted on a position away from the magnet 30 by reducing the angle θ between the two adjacent magnets 30 in the magnet arrangement portion 20. In particular, it can be understood that the magnetic flux density is remarkably increased by setting the angle θ to 10 ° or less.

Example 4 and Comparative Example 5
Below, using Example 4 and Comparative Example 5, the angle θ between the magnets 30 that are closest to each other is the same, but the magnetic treatment device according to Example 4 in which the magnets 30 are not evenly arranged and the magnet 30 A magnetic therapeutic device according to Comparative Example 5 that is evenly arranged is compared.

FIG. 22A is a conceptual diagram illustrating the arrangement of the magnets 30 in the magnetic therapy apparatus according to the fourth embodiment. The magnetic treatment device according to the fourth embodiment includes 18 magnet arrangement portions 20 arranged along the circumferential direction 14 surrounding the ring center position 12, and each magnet arrangement portion 20 includes two magnets 30. Have. The magnetic pole direction of the magnet 30 is aligned so that the N pole faces the inner diameter side and the S pole faces the outer diameter side. The angle θ seen from the ring center position 12 between two adjacent magnets 30 in the same magnet arrangement part 20 is 5 °, and the angle δ seen from the ring center position 12 between two adjacent magnet arrangement parts 20 is 20 °. .

FIG. 22 (b) is a conceptual diagram showing the arrangement of the magnets 30 in the magnetic therapy device according to Comparative Example 5. In the magnetic therapy device according to the comparative example 5, the magnets 30 are evenly arranged along the circumferential direction 14 surrounding the ring center position 12. The magnetic pole direction of the magnet 30 is aligned so that the N pole faces the inner diameter side and the S pole faces the outer diameter side. The angle θ viewed from the ring center position 12 between two adjacent magnets 30 is 5 °.

Like the magnetic treatment device according to Comparative Example 5, the total weight mb of the magnets included in the magnetic treatment device in which the magnets 30 are evenly arranged at the angle θ is the density ρ of the cylindrical magnet 30, the radius R of the magnet, the magnet Using the axial length L of 30 is expressed by the following Equation 3.

mb = π × ρ × R ² × L × 360 / θ (Formula 3)

As can be understood from Equation 3, the magnetic treatment device in which the magnets 30 are evenly arranged at the angle θ is inversely proportional to the value of θ when θ is reduced for the purpose of exerting a strong magnetic flux at a position away from the magnet 30. Thus, it can be understood that the total weight mb of the magnet 30 becomes heavy. Further, when the value of θ is reduced as in the comparative example 5, there is a possibility that the connecting portion for connecting the magnet 30 may not have sufficient flexibility.

On the other hand, as in the magnetic therapy device according to the fourth embodiment (see FIG. 22A), the magnet arrangement unit 20 that arranges the n magnets 30 at the angle θ is arranged in the circumferential direction at intervals of the angle δ. The total weight ma of the magnets 30 included in the magnetic therapy device is expressed by the following Equation 4 using the density ρ of the columnar magnet 30, the radius R of the magnet, and the axial length L of the magnet 30.

ma = π × ρ × R ² × L × 360 × n / δ (Formula 4)
(However, δ> nθ)

When it is desired to obtain the effect of halving the total weight of the magnets included in the magnetic therapy device as compared with the magnetic therapy device according to Comparative Example 5 with respect to the magnetic therapy device according to Example 4, By substituting Equation 3 and Equation 4, the relationship of Equation 2 shown in the first embodiment is derived.

ma ≦ mb / 2 (Formula 5)
δ ≧ 2 × n × θ (Formula 2)

In the magnetic therapy device according to Example 4 shown in FIG. 22A, the angle δ is 20 °, the angle θ is 5 °, and the number of the magnets 30 included in one magnet arrangement unit 20 is two. Therefore, the relationship of Formula 2 is satisfied. As described above, the magnetic therapy device according to the fourth embodiment can exert a strong magnetic flux at a position away from the magnet 30 and can effectively reduce the weight of the magnetic therapy device. In addition, by increasing the angle δ and widening the interval between the magnet arrangement portions 20, the connection portion can have sufficient flexibility, and the adhesion of the magnetic treatment tool to the treatment site is improved. Furthermore, since the magnetic therapy device according to Example 4 can reduce the number of magnets included in the magnetic therapy device, a cost reduction effect can also be expected.
