Description

Technical Field

[0001] The present invention relates to a magnetic irradiation device.

Background Art

[0002] Conventionally, it has been known that a jewelry equipped with a permanent magnet can be worn around the neck, wrists, ankles, etc. of the body, and the magnetism of the permanent magnet can act on the human body to promote blood circulation and improve the health of the user (see, for example, Patent Documents 1 and 2).

[0003] Patent Document 1 describes a permanent magnet ring formed by magnetically attracting a plurality of permanent magnets to each other in a ring shape. By wearing this on the arm, neck, ankle, etc., it is shown that blood circulation promotion and the like can be achieved. Patent Document 2 describes a magnetic therapeutic device provided with a plurality of permanent magnets adapted to the body, and having opposite polarities on the surfaces of adjacent permanent magnets that are adapted to the body. It is shown that stiff shoulders can be effectively eliminated.

[0004] However, since the magnetic field generated by the permanent magnet fixed to the above-described jewelry is a steady magnetic field in which the N pole and the S pole do not interchange, the range of the magnetic field is narrower than that of an alternating magnetic field in which the N pole and the S pole interchange. That is, in the alternating magnetic field, a magnetic field is formed separately from the steady magnetic field by the induced current generated thereby, so the range of the magnetic field is wider than that of the permanent magnet (steady magnetic field). For this reason, since magnetism reaches deep into the body, various magnetic stimulation devices such as a magnetic stimulation device for inducing muscle contraction, a magnetic stimulation device for treating urinary incontinence, and a magnetic stimulation device for transcranial treatment using an alternating magnetic field have been put into practical use (see, for example, Patent Document 3).

[0005] The biological magnetic stimulation device described in Patent Document 3 includes two coils arranged such that magnetic poles of opposite polarities are formed toward the living body. By repeatedly passing a pulsed large current (for example, several thousand amperes) through the two coils, a magnetic flux is formed in the living body, and an eddy current is generated around the magnetic flux, and it is shown that this is effective for stimulating nerves and the like in the living body.

BEST MODE FOR CARRYING OUT THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each figure, components having substantially the same function are denoted by the same reference numerals, and redundant descriptions thereof are omitted.

[0013] [First Embodiment] FIG. 1 is a perspective view showing an example of the magnetic irradiation device according to the first embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof.

[0014] This magnetic irradiation device 1 includes, for example, a base 2 disposed on a floor surface or the like, a pair of slide members 3 slidably attached to the base 2, a first fan unit 4A incorporating a first permanent magnet 43A (see FIG. 7), a second fan unit 4B incorporating a second permanent magnet 43B (see FIG. 7), and a pair of attachment members 5 for attaching the first fan unit 4A and the second fan unit 4B (collectively referred to as "fan unit 4" when referring to both) to the slide members 3 respectively.

[0015] In the magnetic irradiation device 1, as the first permanent magnet 43A and the second permanent magnet 43B (collectively referred to as "permanent magnet 43" when referring to both) rotate and move along with the rotation of the blades 413 (see FIG. 4), a magnetic stimulation based on an alternating magnetic field is applied to the target sites 110 (see FIG. 7) such as the shoulders, arms, legs, head, spinal cord, etc. of the body 100 disposed between the first fan unit 4A and the second fan unit 4B.

[0016] The base 2 has a dovetail groove portion 2a formed along its longitudinal direction A. The base 2 may be formed of, for example, a metal material such as wood, resin material, or aluminum.

[0017] The slide member 3 has a substantially prismatic shape, and a dovetail portion 3a that fits into the dovetail groove portion 2a of the base 2 and protrudes is provided on a part of the side surface, enabling the slide member 3 to slide in the longitudinal direction A of the base 2. The slide member 3 may be formed of, for example, a metal material such as wood, resin material, or aluminum. With the slide mechanism of the slide member 3, according to the size of the target site 110 (see FIG. 7) disposed between the first fan unit 4A and the second fan unit 4B, the first fan unit 4A or the second fan unit 4B can be manually moved in the longitudinal direction A of the base 2 to adjust the distance between the first fan unit 4A and the second fan unit 4B.

[0018] The fan unit 4 includes a unit body 41 that sends out air in one direction by a plurality of blades 413 (see FIG. 4), and a pair of decorative plates 42 attached to both surfaces of the unit body 41 and serving as a cover inside the unit body 41.

[0019] The decorative panel 42 has a plurality (for example, four) of openings 42a for intake and discharge of air by the unit body 41. The decorative panel 42 may be formed of a plate material made of, for example, a metal material such as wood, a resin material, or aluminum.

[0020] (Configuration of the unit body) FIG. 4 shows an example of the unit body 41, where (a) is a front view and (b) is a cross-sectional view taken along line C-C of (a). As shown in FIG. 4(a), the unit body 41 includes a rectangular frame portion 411 having an opening at the center, a motor portion 412 disposed in the opening of the frame portion 411, a plurality (for example, eight) of blades 413 that extend radially from the rotating portion of the motor portion 412 and rotate by driving of the motor portion 412, and a plurality (for example, eight) of permanent magnets 43 that are attached to both surfaces of a part (for example, four) of the plurality of blades 413 by an adhesive or the like.

[0021] The plurality of blades 413 of the first fan unit 4A and the plurality of blades 413 of the second fan unit 4B are arranged on the same axis with a predetermined interval therebetween. That is, as shown in FIG. 1, the center line Oa of the first fan unit 4A and the center line Ob of the second fan unit 4B coincide. The blades 413 are formed of a non-magnetic material. Note that the number of the blades 413 is not limited to eight. Also, the number of the permanent magnets 43 attached to one surface of the blade 413 is not limited to four. Further, the permanent magnets 43 may be attached to all the blades 413.

[0022] Here, the motor portion 412 and the plurality of blades 413 of the first fan unit 4A are examples of a first drive portion and a first rotating body, respectively. The motor portion 412 and the plurality of blades 413 of the second fan unit 4B are examples of a second drive portion and a second rotating plate, respectively.

[0023] The motor units 412 of the first fan unit 4A and the second fan unit 4B rotate a plurality of blades 413 in opposite directions when viewed from the right side B in FIG. 3 by a control unit 10 (see FIG. 5) described later. Further, the motor unit 412 can change the rotation speed in the range of, for example, 500 to 2400 rpm.

[0024] As shown in FIG. 4(a), the permanent magnets 43 are attached to four blades 413 on the same circle (for example, a circle with a diameter of 5 to 7 cm) D at equal intervals (for example, 90° intervals) so that the polarities of the permanent magnets 43 arranged on the outer and inner surfaces of the blade 413 are alternately different in the circumferential direction. That is, the permanent magnets 43 arranged on the same circle of the blade 413 visible on the front side in FIG. 4(a) have alternately different polarities of N-pole face 43a, S-pole face 43b, N-pole face 43a, and S-pole face 43b. Further, as shown in FIG. 4(b), a pair of permanent magnets 43 arranged at the same position with the blade 413 interposed therebetween are attached to the blade 413 so that the polarities are different from each other. Note that when the magnetic force of the permanent magnet 43 is sufficient, it may be arranged on either the outer surface or the inner surface of the blade 413.

[0025] The permanent magnet 43 has a cylindrical shape, and for example, a neodymium magnet, a samarium cobalt magnet, a samarium magnet, or the like can be used. The magnetic force of the permanent magnet 43 is preferably, for example, 300 to 500 mT. Note that the permanent magnet 43 may have another shape such as a prismatic shape.

[0026] (Configuration of the control system of the magnetic irradiation device) FIG. 5 is a block diagram showing an example of the control system of the magnetic irradiation device 1. The magnetic irradiation device 1 has a control unit 10 that controls each part of the magnetic irradiation device 1, and an operation unit 11 and the motor units 412 of the first fan unit 4A and the second fan unit 4B are connected to the control unit 10.

[0027] The operation unit 11 is composed of a selection button, a dial, a touch panel, etc. so that the rotation speed of the motor units 412 of the first fan unit 4A and the second fan unit 4B can be input or selected.

[0028] Based on the rotational speed Na input or selected from the operation unit 11, the control unit 10 transmits a rotational speed command signal corresponding to the rotational speed Na to the motor unit 412 of the first fan unit 4A, and rotates the motor unit 412 of the first fan unit 4A shown in FIG. 3 in the left direction when viewed from the right side B. Further, based on the rotational speed Na input or selected from the operation unit 11, the control unit 10 transmits a rotational speed command signal corresponding to the rotational speed Na to the motor unit 412 of the second fan unit 4B, and rotates the second fan unit 4B shown in FIG. 3 in the right direction when viewed from the right side B.

[0029] (Operation of the Magnetic Irradiation Device) Next, the operation of the magnetic irradiation device 1 will be described with reference to FIGS. 6 and 7. FIG. 6 is a perspective view for explaining the eddy current generated by the movement of the permanent magnet 43. FIG. 7 is a schematic diagram for explaining the principle of the magnetic irradiation device 1. In FIG. 7, only the eddy current 432 on the front side is illustrated.

[0030] As shown in FIG. 6, when the permanent magnet 43 moves in the left direction Y, as shown in the figure, based on the principle of Arago's disk, a downward central magnetic flux 431a is generated, eddy currents 432 are generated in the directions shown in the figure on both sides of the central magnetic flux 431a, and a magnetic field is generated at the center of the eddy currents 432.

[0031] As shown in FIG. 7, the target site 110 is arranged between the first fan unit 4A and the second fan unit 4B, the blades 413 of the first fan unit 4A are rotated in one direction (for example, the left direction) when viewed from the right side B, and the blades 413 of the second fan unit 4B are rotated in the other direction (for example, the right direction) when viewed from the right side B.

[0032] There are times when the first permanent magnet 43A of the first fan unit 4A and the second permanent magnet 43B of the second fan unit 4B are spatially aligned in the same direction. That is, as shown in FIG. 7, the magnetic flux 431a at the center of the first permanent magnet 43A and the magnetic flux 431b at the center of the second permanent magnet 43B coincide. From left to right, the S - pole surface 43b, N - pole surface 43a, central space, S - pole surface 43b, and N - pole surface 43a are arranged, and there are times when the magnetic field strength becomes stronger. As shown in FIG. 7, magnetic flux (magnetic force lines) 431 is generated from the first permanent magnet 43A and the second permanent magnet 43B, and the magnetic flux 431 reaches deep into the target site 110, generating eddy currents 432. Thereby, magnetic stimulation by the eddy currents 432 can be applied to the deep part of the target site 110.

[0033] (Effect of the First Embodiment) According to the magnetic irradiation device 1 according to the first embodiment, the following effects can be obtained. (a) Magnetic flux 431 is generated from the first permanent magnet 43A and the second permanent magnet 43B of the first fan unit 4A and the second fan unit 4B provided on both sides of the target site 110 toward the deep part of the target site 110, and eddy currents 432 are generated around it. Therefore, it is possible to irradiate the deep part of the target site 110 with magnetism by a non - invasive method. Compared with the case where magnetism is irradiated only from one side using one fan unit, blood circulation in the target site 110 can be further promoted, and the health of the subject can be improved. (b) Since the blades 413 of the fan unit 4 are used as the rotating plate, the magnetic irradiation device 1 can be manufactured at low cost.

[0034] [Second Embodiment] FIG. 8 is a diagram for explaining a second embodiment of the present invention, and is a diagram schematically showing the positions of the first permanent magnet 43A and the second permanent magnet 43B when the first fan unit 4A and the second fan unit 4B are viewed from the right side B. In the first embodiment, the motor units 412 of the first fan unit 4A and the second fan unit 4B are rotated in opposite directions at the same rotational speed. However, in the present embodiment, the rotational speeds of the motor units 412 of the first fan unit 4A and the second fan unit 4B are made different.

[0035] For the motor units 412 of the first fan unit 4A and the second fan unit 4B, in order to achieve a high-precision rotational speed, for example, a stepping motor or the like may be used.

[0036] It is assumed that the first permanent magnet 43A and the second permanent magnet 43B of the first fan unit 4A and the second fan unit 4B are located at the position P1 before the start of rotation. The four positions P1 in the figure are arranged at equal intervals (90° intervals). When the first permanent magnet 43A of the first fan unit 4A rotates leftward at the rotational speed Na when viewed from the right side B in FIG. 3, and the second permanent magnet 43B of the second fan unit 4B rotates rightward at the rotational speed Na when viewed from the right side B in FIG. 3, the first permanent magnet 43A and the second permanent magnet 43B overlap at the position P2 (θ = 45°). Further, when the first permanent magnet 43A rotates leftward and the second permanent magnet 43B rotates rightward, next, the first permanent magnet 43A and the second permanent magnet 43B overlap at the position P1. After that, the first permanent magnet 43A and the second permanent magnet 43B alternately overlap at eight positions such as position P2 and position P1. That is, the positions where the magnetic field is irradiated to the target site 110 are limited to eight positions.

[0037] In the second embodiment, the rotational speed of the motor unit 412 of the first fan unit 4A in the left direction is set as Na (rpm), and the rotational speed of the motor unit 412 of the second fan unit 4B in the right direction is set as Nb (rpm), so as to cause a rotational speed difference ΔN (rpm) between the two. Thereby, the overlapping position of the first permanent magnet 43A and the second permanent magnet 43B as viewed from the right side B in FIG. 3 can be increased compared to the case where the rotational speeds of the left and right motor units 412 are the same. For example, when Na is 1250 rpm and Nb is 1000 rpm, as shown in FIG. 8, Δθ can be set to about 5° with respect to θ = 45°, and the overlapping positions of the first permanent magnet 43A and the second permanent magnet 43B such as P3, P4, P5, P6, ··· can be made 16 or more. Here, the rotational speed difference ΔN is an example of a predetermined difference.

[0038] According to the magnetic irradiation device 1 according to the second embodiment, compared with the first embodiment, the position where the central magnetic flux 431a from the first permanent magnet 43A and the central magnetic flux 431b from the second permanent magnet 43B coincide can be increased, and the blood circulation of the subject can be further promoted compared with the first embodiment.

[0039] (Specific examples of the target site) FIGS. 9(a) to (d) are perspective views showing specific examples of the target site 110. The target site 110 of the body 100 can be various sites according to the purpose. For example, it may be the shoulder 111 shown in FIG. 9(a), the arm 112 shown in FIG. 9(b), the leg 113 shown in FIG. 9(c), or the head 114 shown in FIG. 9(d).

[0040] FIG. 10(a) is a side view showing another specific example of the target site 110, and FIG. 10(b) is a cross-sectional view taken along line E-E of FIG. 10(a). When the spinal cord 115 of the body 100 is taken as the target site 110, as shown in FIG. 10(a), a housing 200 having a U-shaped cross-section with a plurality (for example, three) of magnetic irradiation devices 1 arranged in the longitudinal direction of the body 100 is prepared between the head-side mat 120A and the foot-side mat 120B. Next, the subject is laid on the head-side mat 120A, the lower part of the housing 200, and the foot-side mat 120B. The head is placed on the pillow 121. By simultaneously driving the plurality of magnetic irradiation devices 1, the spinal cord 115 can be irradiated with magnetic fields from above and below.

[0041] When the target site 110 is the head 114 or the spinal cord 115, for example, symptoms of neurological diseases such as Parkinson's disease can be alleviated. That is, in Parkinson's disease, ionic species such as phosphorus ions (P 3- ) and phosphate ions (PO4 3- ) in phosphatidylinositol 3-phosphate (PIP3) in the brain bind to α-synuclein (protein), and α-synuclein aggregates, and it is known that the progression of this aggregation leads to the onset of the disease. By vibrating the ionic substances (for example, Na + , K + , Ca 2+ , Mg 2+ , Cl - , etc.) dissolved in the body fluid of the body 100 and dissolved oxygen O2 by magnetic irradiation with the magnetic irradiation device 1 according to the present embodiment, the cells are activated and the aggregates of α-synuclein are dispersed, and symptoms of neurological diseases such as Parkinson's disease can be alleviated.

[0042] As described above, the embodiments of the present invention have been described. However, the embodiments of the present invention are not limited to the above-described embodiments, and various modifications and implementations are possible. In each of the above embodiments, it has been described that it is effective for promoting blood circulation of the subject and alleviating symptoms of neurological diseases. However, the present invention is not limited thereto, and it is effective for alleviating various symptoms that are said to be improvable by magnetic stimulation.
