Description

  The present invention relates to a magnetic therapy device, and more particularly to a magnetic therapy device used by being attached to a body.

  For a long time, a magnetic therapy device has been widely known in which a magnet is disposed on an adhesive surface of an adhesive tape and can be used by being attached to a site with stiff shoulders or low back pain. By wearing such a magnetic therapy device on the body, it is said that the so-called affected part is magnetized to relieve stiff shoulders and back pain.

  In such a magnetic therapy device, it is known that the state of the affected area is better in the case of a fluctuating magnetic field in which the magnetic force and the magnetic pole appropriately change than the so-called static magnetic field in which the affected area is given a constant magnetic force and magnetic pole. In recent years, it has been proposed to move the magnet of a magnetic therapy device attached to the body. As such a magnetic therapy device, for example, a magnetic therapy device as disclosed in Patent Document 1 is known.

In the magnetic therapy device shown in the cited reference 1, since the magnet is movably enclosed in the internal space of the small chamber body provided in the sticking body having the adhesive layer, such a time therapy device is mounted. In everyday life in the state, the magnet moved in the inner space of the small chamber body, and a large amount of fluctuation of the magnetic field was expected, but in reality the magnet sealed in the small chamber body often slides, There is a problem that almost no pair can be expected for the change of the magnetic pole, and sufficient magnetic field fluctuation cannot be applied to the affected area.
In addition, such a small body has a problem that it is damaged by an impact given in daily life.

  Therefore, the present invention can provide a sufficient magnetic field fluctuation to the affected part by moving the magnet accommodated in the capsule part with the change of the magnetic pole, thereby improving the strength of the capsule part. An object is to provide a magnetic therapy device that can greatly reduce the risk of breakage.

  The present invention comprises an adhesive sheet having at least one surface as an adhesive surface, a capsule portion fixed to a surface opposite to the adhesive surface of the adhesive sheet, and a magnet accommodated in an internal space of the capsule portion. In the magnetic treatment device, in the internal space of the capsule portion, a protrusion extends from the ceiling portion of the capsule portion toward the bottom surface, and the magnet circulates around the protrusion in the internal space of the capsule portion. It is a magnetic therapy device characterized by being formed into a possible rotating body.

  Moreover, as another invention, at least one surface is an adhesive sheet, a capsule part fixed to a surface opposite to the adhesive surface of the adhesive sheet, and a magnet accommodated in the internal space of the capsule part, , Wherein the capsule part is formed in a ring-shaped space, and the magnet is formed in a rotating body that can circulate in the ring-shaped space of the capsule part. It can also be set as a magnetic therapy device.

  The magnet formed on the rotating body is characterized in that magnetic poles are alternately provided in the circumferential direction of the rotating surface. Thereby, the fluctuation | variation of the magnetic field given by the magnet which orbits the inside of a capsule can be enlarged.

  Further, the magnet formed on the rotating body is formed by connecting a plurality of magnet pieces. Further, these magnet pieces are preferably formed in a plate shape. As described above, the magnetic pole states alternately arranged in the circumferential direction of the rotating surface can be easily provided.

  The plate-shaped magnet piece is characterized in that a magnetic pole is magnetized in the plate thickness direction. Thereby, the magnetic force of the same strength can be applied over the whole area of the inner diameter side and the outer diameter side of the capsule portion inner space.

  The magnet formed on the rotating body is characterized in that a height dimension on the outer diameter side of the capsule part is formed higher than a height dimension on the protruding part side. As a result, the magnet can easily circulate in the space inside the capsule around the protruding portion, so that the amount of fluctuation of the magnetic field applied to the affected part can be increased.

  According to the magnetic therapy apparatus according to the present invention, the magnet extends around the protruding portion in the internal space of the capsule portion by disposing the protruding portion extending from the ceiling portion to the bottom surface portion in the internal space of the capsule portion. Since it is formed in a space shape that can be circulated, the magnet formed on the rotating body makes a circular motion around the protrusion, and can greatly increase the fluctuation of the magnetic field applied to the affected area. Further, by providing the capsule portion with the protruding portion, the mechanical strength of the capsule portion can be improved, and the risk of breakage of the capsule portion in daily life can be greatly reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view of a magnetic therapy device in the present embodiment. 2 is a cross-sectional view taken along line AA in FIG. FIG. 3 is a perspective view of the magnet in the present embodiment.
As shown in FIGS. 1 and 2, the magnetic therapy device 50 according to the present embodiment fixes the capsule part 20 containing the magnet 30 on the back surface 14 of the so-called double-sided tape 10 whose front surface 12 and back surface 14 are adhesive surfaces. It is a thing. It is preferable to use the pressure-sensitive adhesive used in the medical pressure-sensitive adhesive tape for the surface 12 which is the surface to be attached to the affected area.

  The capsule part 20 in the present embodiment is formed in a dome-like internal space by a ceiling part 22 whose central part protrudes outward, a side wall part 24 continuous to the ceiling part 22, and a bottom plate 26. In the internal space of the capsule portion 20, a protruding portion 28 extending from the ceiling portion 22 on the inner wall surface of the central portion of the ceiling portion 22 toward the bottom plate 26 is disposed. Here, as shown in FIG. 2, the protruding portion 28 is disposed so as to allow the ceiling portion 22 and the bottom plate 26 to communicate with each other. Such a protruding portion 28 can function as a support for improving the mechanical strength of the capsule portion 20. With such a columnar protrusion 28, the internal space of the capsule portion 20 can be configured as a donut-shaped space.

  The capsule portion 20 is formed by integrally forming the ceiling portion 22, the side wall portion 24, and the projecting portion 28 with synthetic resin or the like, and accommodating the magnet 30 between the projecting portion 28 and the side wall portion 24, and then separately separating the same with the same synthetic resin. It can be formed by contacting the bottom plate 26 with the side plate 24 and the edge of the side wall 24 and the protruding portion 28 and the bottom plate 26 by ultrasonic bonding or the like. As the material of the capsule part 20, it is preferable to use a synthetic resin material that is transparent and excellent in mechanical strength, such as acrylic, but is not necessarily transparent as long as it has the necessary mechanical strength. It need not be a synthetic resin material.

The magnet 30 is disposed in the internal space of the capsule part 20 formed in the donut-shaped space as described above. The magnet 30 in the present embodiment is formed in a cylindrical shape that is a rotating body as shown in FIG. The cylindrical magnet 30 in the present embodiment connects the side wall portions of a plurality of plate magnets 32 which are magnet pieces having a cross-sectional shape formed in an arcuate belt shape, and the cylindrical magnet 30 which is a rotating body. Is formed. Since the plate-like magnet 32 in the present embodiment uses a magnet whose magnetic poles are magnetized in the longitudinal direction, like a so-called bar magnet, the rotating magnet 30 can be obtained at low cost.
When the plate magnets 32 are connected to each other, the magnetic poles at both ends of the plate magnet 32 are connected so as to appear alternately in the circumferential direction of the rotating surface. Moreover, when connecting the plate-shaped magnets 32, it is preferable to connect via a separator (not shown).

  The cylindrical magnet 30 formed in this manner circulates in the internal space of the capsule part 20 formed in a donut shape by the columnar protrusions 28 with the columnar protrusions 28 as the center of rotation. become. The length of the cylindrical magnet 30 is determined by the distance between the columnar protrusion 28 of the capsule portion 20 and the inner wall surface of the side wall portion 24 of the capsule portion 20 (the passage width of the donut-shaped space of the capsule portion 20). Therefore, the cylindrical magnet 30 circulates only in any direction of the arrow Z direction shown in FIG. Further, the height of the magnet 30 is slightly lower than the height of the side wall 24 of the capsule part 20.

  Further, if at least one of the bottom plate 26 of the capsule unit 20 and the rotating surface of the magnet 30 is subjected to anti-slip processing (coating process or uneven processing on the surface), the magnet 30 goes around the inner space of the capsule unit 20. This is suitable without sliding.

(Second Embodiment)
FIG. 4 is a perspective view of the magnet in the present embodiment.
The magnet 30 in the present embodiment has a peripheral length on the side wall portion 24 side (the outer diameter side of the capsule portion 20) that is longer than a peripheral length on the columnar protruding portion 28 side (the inner diameter side of the capsule portion 20). The magnet 30 is formed in the shape of a truncated cone. The height dimension on the outer peripheral part side of the magnet 30 is the same as that of the previous embodiment in that it is formed slightly lower than the height dimension of the side wall portion 24.
By adopting the magnet 30 having such a shape, the magnet 30 does not slip on the columnar protrusion 28 side, and the magnet 30 can be reliably rotated. This is preferable in that it can be generated.

(Third embodiment)
FIG. 5 is a perspective view of the magnet in the present embodiment.
In the present embodiment, the magnet 30 is formed by connecting the side wall portions of a plurality of plate-like magnets 32 that are magnet pieces having a cross-sectional shape formed in an arcuate belt shape. Although it is the same as that of 2nd Embodiment, it is the point that the magnetic pole of the plate-shaped magnet 32 is magnetized by the plate | board thickness direction. In the present embodiment, as shown in FIG. 5, the first plate magnet 32a having an N pole on the outer peripheral side and the S pole on the inner peripheral side, and a first plate magnet 32a having an S pole on the outer peripheral side and an N pole on the inner peripheral side. A cylindrical magnet 30 is configured by alternately connecting the two plate magnets 32b. The height dimension of the magnet 30 in this embodiment is the same as that in the first embodiment.

  The cylindrical magnet 30 is formed using the plate magnets 32a and 32b magnetized in the plate thickness direction, so that the magnetic pole at the contact portion between the magnet 30 and the bottom plate 26 has a donut shape of the capsule portion 20. This is advantageous in that it can be made to coincide with the entire width of the passageway of the space (from the columnar protruding portion 28 side to the side wall portion 24). It is also advantageous in that the magnetic force does not weaken at an intermediate position of the passage width of the doughnut-shaped space of the capsule portion 20 (from the columnar protruding portion 28 side to the side wall portion 24).

(Fourth embodiment)
FIG. 6 is a plan view and a cross-sectional view of the capsule portion in the present embodiment.
The magnetic therapy device 50 is preferably formed to a size that does not give a sense of incongruity when affixed to the body (a planar dimension of the diameter is about 10 mm and a thickness dimension is about 5 mm). If it is such a size, it may not be necessary to reinforce the mechanical strength of the capsule part 20. In such a case, it is only necessary that the magnet 30 can circulate only in a predetermined direction in the internal space of the capsule unit 20. That is, as shown in FIG. 6, it is not necessary for the projecting portion 28 to communicate with the ceiling portion 22 and the bottom plate 26, and the cantilevered portion of the ceiling portion 22 has a length up to the midway height position of the capsule portion 20.

By adopting such a shape of the capsule portion 20, the arrangement of the protruding portion 28 can be omitted, which is preferable in that the configuration can be simplified.
Moreover, the ring-shaped capsule part 20 can obtain the same mechanical strength as the capsule part 20 provided with the columnar protrusions 28, and there is no problem with respect to the mechanical strength. Furthermore, since the magnet 30 accommodated in the internal space of the ring-shaped capsule portion 20 inevitably circulates in the direction of the arrow Z in the drawing along the shape of the internal space, the same as in the above-described embodiments. The effect of this can be obtained.
Such a ring-shaped capsule part 20 can be easily manufactured by using a resin molding die. The magnet 30 used here was also a spherical body as shown in FIG.
