The method of attaching the rotating magnetic therapy device 1 to the skin S is particularly limited as long as the rotating magnetic therapy device 1 is in direct or indirect contact with the skin S of the human body for a period during which the magnetic therapeutic effect is obtained. Instead, for example, a method of directly adhering to the skin S using an attachment band or the like, a method of indirectly adhering to the skin S via a known adhesive means such as an adhesive sheet, or the like can be adopted. Also, the position of the skin S to which the rotating magnetic therapy device 1 is attached is not particularly limited as long as it is a position where the magnetic therapy effect is exhibited, and any position such as the shoulder, arm, neck, waist, leg, etc. of the human body can be used. It can be a position.

As shown in FIGS. 1 and 2, the rotating magnetic therapy device 1 of this embodiment supports a housing 2, a therapeutic magnet unit 3 housed in the housing 2, and a therapeutic magnet unit 3. A support base 4 and a rotation drive device 5 for rotating the support base 4 are provided. As will be described in detail below, the rotary magnetic therapy device 1 rotates the therapeutic magnet unit 3 supported by the support base 4 by rotating the support base 4 with the rotary drive device 5, thereby applying the magnetic field to the skin S of the human body. produces a fluctuating magnetic field.

The rotating magnetic therapy device 1, in this embodiment, supplies power to the circuit board 9 for controlling the operation of the rotating magnetic therapy device 1, and to the circuit board 9 and the rotary drive device 5, as shown in FIG. It further comprises a battery 10, a switch 11 for turning on/off the rotating magnetic therapy device 1, and a USB terminal 12 for supplying power to the battery 10 from the outside in order to charge the battery 10. The rotating magnetic therapy device 1 further includes a circuit board 9, a battery 10, a switch 11, and a USB terminal 12, thereby functioning as a single controllable magnetic therapy device. However, the rotating magnetic therapy device 1 is not limited to this embodiment, and may be operated by external control without having the circuit board 9, the battery 10, the switch 11 and the USB terminal 12.

The housing 2 accommodates components that make up the rotating magnetic therapy device 1 . As shown in FIG. 1(b), the housing 2 is arranged at a position in direct or indirect contact with the skin S of the human body when the rotating magnetic therapy device 1 is attached to the skin S of the human body. The housing 2 has an internal space that accommodates the components that make up the rotating magnetic therapy device 1. The internal space is surrounded by a top surface, a side surface, and an area where the rotating magnetic therapy device 1 is attached to the skin S. It has a bottom surface 21 that comes into direct or indirect contact with the skin S when it is closed. The rotating magnetic therapy device 1 is used by being attached to the skin S of the human body so that the bottom surface 21 of the housing 2 contacts the skin S of the human body directly or indirectly.

In this embodiment, the housing 2 is formed in a substantially columnar shape or a substantially disk shape, as shown in FIGS. 1(a) and 1(b). However, the housing 2 is particularly limited as long as it has an internal space for housing the components of the rotating magnetic therapy device 1 and has a bottom surface 21 that directly or indirectly contacts the skin S of the human body. Instead, they may be formed in a substantially prismatic shape or the like. In addition, although the material constituting the housing 2 is not particularly limited, it has a strength capable of protecting the contained components against the force received from the outside, and the magnetic force lines of the therapeutic magnet unit 3 is preferably permeable, and synthetic resin materials such as acrylonitrile-butadiene-styrene (ABS), polycarbonate acrylonitrile-butadiene-styrene (PC-ABS), polyethylene (PE), and polyethylene terephthalate (PET) can be preferably used.

The therapeutic magnet section 3 has two magnetic poles (N pole, S pole) and generates a magnetic field that can affect the skin S of the human body. As shown in FIG. 2 , the therapeutic magnet unit 3 is supported by a support base 4 and rotated by the rotary drive device 5 to generate a varying magnetic field. In this specification, the term "varying magnetic field" means a magnetic field whose direction and strength fluctuate. The rotating magnetic therapy device 1 generates a fluctuating magnetic field by rotating the therapeutic magnet unit 3, thereby eliminating the so-called "familiarity" of the skin S surface and the vicinity of the skin S surface in the body, thereby exhibiting a high magnetic therapeutic effect. can do.

The therapeutic magnet unit 3 is shown in FIGS. 2 and 3, and as will be described in more detail below, the support base 4 rotates about a rotation axis 6 extending substantially perpendicular to the bottom surface 21 of the housing 2. As a result, it rotates in a plane substantially parallel to the bottom surface 21 of the housing 2 . When the rotating magnetic therapy device 1 is attached to the skin S of the human body, the therapeutic magnet portion 3 rotates in a plane substantially parallel to the bottom surface 21 of the housing 2, thereby spreading over a wide range of the skin S. A varying magnetic field can be produced over the entire length.

In this embodiment, the therapeutic magnet section 3 includes a plurality of (two in the illustrated example) therapeutic magnets 3a and 3b, as shown in FIGS. The plurality of therapeutic magnets 3a and 3b have magnetic pole directions that extend substantially perpendicularly to the bottom surface 21 of the housing 2. The matching therapeutic magnets 3a, 3b have magnetic pole directions that face substantially opposite directions. The plurality of therapeutic magnets 3a and 3b are arranged separately from each other along the rotation direction of the support base 4, and the plurality of therapeutic magnets 3a and 3b are rotated by the rotation of the support base 4 to alternate. configured to generate a magnetic field; In the illustrated example, the therapeutic magnet 3a is magnetized so that the bottom surface 21 side is the S pole and the side opposite to the bottom surface 21 is the N pole (the magnetic pole direction is directed toward the bottom surface 21 side). 3b is magnetized so that the bottom surface 21 side is the N pole and the side opposite to the bottom surface 21 is the S pole (the magnetic pole direction is directed to the side opposite to the bottom surface 21). Therefore, at a specific position on the rotational orbit of the therapeutic magnets 3a and 3b, each time the support base 4 rotates once, the upward and downward magnetic fields in the substantially vertical direction with respect to the bottom surface 21 of the housing 2 are generated once. occur alternately. In this way, since the therapeutic magnet section 3 includes a plurality of magnets whose magnetic pole directions are opposite to each other, changes in the magnetic field intensity received by the skin S when the therapeutic magnet section 3 is rotated are oriented in the same direction. Compared to using a magnet with a facing magnetic pole direction, it is nearly twice as large and can generate a larger fluctuating magnetic field. Furthermore, the magnetic pole direction of the therapeutic magnets 3a and 3b to be used extends substantially perpendicular to the bottom surface 21 (and the surface of the skin S) of the housing 2, so that the magnetic pole direction is parallel to the bottom surface 21 (and the surface of the skin S). The magnetic field strength in the direction substantially perpendicular to the surface of the skin S is greater than in the case of using a magnet extending into the skin S, and the magnetism can act from the surface of the skin S to a deeper part of the body.

However, the plurality of therapeutic magnets 3a and 3b may be arranged at different distances from the approximate center of the support base 4, respectively. Further, the respective distances of the plurality of therapeutic magnets 3a and 3b from the substantial center of the support base 4 can be appropriately set according to the range of the skin S desired to exert the magnetic therapeutic effect.
