Conventionally, as one of the magnetic therapy devices of this type, as shown in FIG. 12, a magnetic therapy device 1 having a structure in which a short columnar magnet piece 3 is attached to the center of a circular bandage 2 is developed and marketed. ing. In this, as shown in FIG. 13, the adhesive plaster 2 is directly attached to the skin 4 so that the magnet piece 3 is in close contact with the skin 4 of the human body.

[0003]

However, in the above-mentioned magnetic therapy device 1, since the magnet piece 3 is only held by the adhesive force of the bandage 2, the holding force is weak, and depending on the handling, the magnet band 3 may be used. The problem that the piece 3 falls off easily occurs. However, if the adhesive force of the adhesive plaster 2 is increased, it is difficult to peel the adhesive plaster 2 from the skin 4 of the human body. Further, when performing magnetic treatment over a wide range of the human body surface, a plurality of magnetic treatment devices 1 may be attached within the range. However, it is troublesome to align a plurality of magnetic therapy devices 1 so that they do not overlap the body surface of the human body and accurately attach them to the most effective position. It is more difficult to attach. Therefore, a large-sized magnet piece may be manufactured, but it is difficult to adhere the large-sized magnet piece along the body surface shape of the human body. In addition, since the adhesive bandage 2 has a structure that is directly applied to the skin 4, it is likely to cause eczema and a rash, and is particularly unsuitable for application to a site such as a wound or an allergic constitution. is there. By the way, recently, as one of the fungal diseases that develop with medical treatment, candidiasis that occurs in the part where the plasters and various medical tapes are attached has been reported. Diseases also tend to develop.

[0009]

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a magnetic therapeutic device of this embodiment, and FIG. 2 is a sectional view thereof. The magnetic therapy device 10 is
A thin sheet 11 having elasticity and flexibility, a plurality (here, three) of magnets 21 arranged on the surface (upper) of the thin sheet 11, and the thin plate with the magnets 21 embedded therein. The polyurethane resin 31 held on the sheet 11 is included.

The thin sheet 11 is formed into a circular shape from soft transparent vinyl chloride or the like, and an adhesive layer 12 is applied to the back surface (side surface opposite to the polyurethane resin 31). The adhesive layer 12 is covered with a release sheet 13 which is peeled off at the time of use, for example, with an acrylic adhesive or the like. The size and shape of the thin sheet 11 may be arbitrary. The magnet 21 is configured by magnetizing a magnet element made of a ferromagnetic material (for example, ferrite) formed in a short cylinder shape while being held in the polyurethane resin 31. Here, the number of magnets 21 to be embedded can be arbitrarily selected according to the attachment site and shape of the human body. Further, the shape and arrangement are also arbitrary. The polyurethane resin 31 is a transparent urethane resin that is harmless to the human body used in artificial hearts and the like, and functional ceramic powder and titanium oxide powder are mixed therein at a predetermined ratio.

Next, a method of manufacturing the magnetic therapy device 10 will be described.
This will be described with reference to the process chart of FIG. What melt | dissolves the polyurethane resin 31 in the container 41, and mixes the ceramic powder and the titanium oxide in the predetermined ratio in it is dripped from the nozzle 42 on the thin sheet 11 which has elasticity and flexibility [( See A)]. When the polyurethane resin 31 reaches the end of the thin sheet 11 and the thickness reaches a predetermined value, the dropping of the polyurethane resin 31 is finished [see (B)]. In this state (the state where the polyurethane resin 31 is not cured), the magnet element 21A made of one or more ferromagnetic materials is embedded in the polyurethane resin 31, and the polyurethane resin 31 is left to stand naturally (about 12 hours). put. At this time, you may heat as needed. When the magnet element 21A is buried, the magnet element 21A is buried so that the tip of the magnet element 21A is slightly exposed from the surface of the polyurethane resin 31 or completely buried [see (C)]. Finally, the magnet element 21A is magnetized through the magnetizing device 43 to form the magnet 21 [see (D)].

In use, as shown in FIG. 4, after peeling off the release sheet 13 from the back surface side of the thin sheet 11, the adhesive layer 12 of the thin sheet 11 is attached to clothes or a supporter 51 corresponding to a magnetic treatment target site. wear. Then
Since the magnet 21 comes into contact with the magnetic treatment target portion of the skin 4, the stiff shoulder is treated and the muscle fatigue is recovered by this magnetic effect. Alternatively, instead of sticking the adhesive layer 12 of the thin sheet 11 to the clothes 51 or the like, as shown in FIG. 5, the adhesive layer 12 of the thin sheet 11 may be directly stuck to the skin 4 with a bandage 52. May be.

According to the magnetic therapy device of this embodiment, one or a plurality of magnets 21 are provided on the flexible thin sheet 11.
And the polyurethane resin 31 for holding the magnet 21 in the embedded state on the thin sheet 11 is provided.
Since the magnet 21 is held on the thin sheet 11 while being embedded in the polyurethane resin 31, the magnet 21
The holding power of can be increased. Moreover, since the thin sheet 11 and the polyurethane resin 31 are highly flexible, they can be adhered to the human body along the surface shape of the body, even if they are made in any size and shape. Further, since the polyurethane resin 31 that comes into contact with the skin of the human body is a material that is also harmless to the human body and is also used in artificial hearts, etc., it is less likely to cause eczema, rashes, etc., and has less adverse effects on the human body. You can In addition, since there is no cracking or deterioration of elasticity over a long period of time, the quality can be stabilized.

Further, since the ceramic powder is mixed in the polyurethane resin 31, when the polyurethane resin 31 comes into contact with the body surface, the ceramic powder emits far-infrared rays at the temperature of the body surface, which assists the circulation of blood and heats the body. A synergistic effect with the effect can be expected. That is, a synergistic effect of the magnetic effect and the heating effect can be expected. Furthermore, since titanium oxide powder is mixed in the polyurethane resin 31, antibacterial properties can be expected. In addition, the adhesive layer 12 is formed on the back surface of the thin sheet 11.
Since the adhesive layer 12 is applied, the adhesive layer 12 can be applied to clothes, supporters 51, and the like, which are the treatment site, without needing to be applied to the skin, so that the adverse effect on the human body can be eliminated.

Further, according to the method for manufacturing the magnetic therapeutic device 10 of this embodiment, the molten polyurethane resin 31 is dropped on the thin sheet 11 and the molten polyurethane resin 31 is cured before the molten polyurethane resin 31 is cured. Since one or a plurality of magnet elements 21A are embedded in the magnet, and the magnet element 21A is magnetized after the molten polyurethane resin 31 is hardened, the magnet element 21A has a high holding force and should be adhered to the body surface shape of the human body. Further, it is possible to easily manufacture a magnetic therapeutic device with less adverse effect on the human body.

Although the present invention has been described above with reference to the preferred embodiment, the present invention is not limited to this embodiment, and modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the magnet element 21A is embedded in a state where the tip of the magnet element 21A is slightly exposed from the surface of the polyurethane resin 31, or is completely buried, but as shown in FIG. Magnet element 2
It is also possible to embed the tip of 1A with the tip of the polyurethane resin 31 slightly exposed from the surface, and cover the resin (sheet) 32 which is harmless to the human body on it. Alternatively, FIG.
As shown in, the tip of the magnet element 21A may be embedded in a state of being recessed from the surface of the polyurethane resin 31. By doing so, the magnet element 21A (magnet 21) does not directly touch the skin, and therefore, it can be applied to a person with a metal allergy.

The size and shape of the thin sheet 11 may be arbitrary, but as shown in FIGS. 8 and 9, the thin sheet 11 has a rectangular shape, and a polyurethane resin 31 is provided on the surface thereof. A plurality (here, 10) of magnets 21 may be arranged and held in two rows. Alternatively, as shown in FIG. 10, if it is formed in a crescent shape, it can be adhered along the circumference of the waist or the like. Further, as shown in FIG. 11, it may be configured in a donut shape.

[0018]

According to the magnetic therapy device of the present invention, one or a plurality of magnets arranged on the thin sheet are held on the thin sheet while being embedded in the polyurethane resin. The holding force of the magnet can be increased. Moreover, since the thin sheet and the polyurethane resin are highly flexible, the sheet and the polyurethane resin can be adhered to the body surface shape of the human body even if the sheet and the polyurethane resin are made to have arbitrary sizes and shapes. Furthermore, during use, the polyurethane resin, which is harmless to the human body, comes into close contact with the skin, so that adverse effects on the human body can be reduced. According to the method for manufacturing a magnetic therapeutic device of the present invention, a molten polyurethane resin is dropped on a flexible thin sheet, and one or a plurality of molten polyurethane resins are added to the molten polyurethane resin before the molten polyurethane resin is cured. Since the magnet element is buried and the molten polyurethane resin is hardened and then the magnet element is magnetized, the holding force of the magnet is high, and the magnet can be closely adhered along the body surface shape of the human body. It is possible to easily manufacture a magnetic therapy device with less adverse effect on the magnetic therapy device.
