  Hereinafter, a magnetic therapy device according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the magnetic treatment device 1 according to the present invention includes a curved substantially square base portion 2, a magnet body 3, and an adhesive layer 4.

  As shown in FIG. 2A, the base portion 2 is formed of a bag-like flexible film 2a and a soft resin material 2b enclosed in the flexible film 2a. Since the said base part 2 is formed in a bag shape, it has the surface 1a and the skin surface 1b. Moreover, as shown in FIG.1 (b), it curves and forms so that it may become convex along so that it may be easy to follow a wearer's skin, and upper part is made into the surface 1a. The bag-like flexible film 2a is made of, for example, polyurethane, and the soft resin material 2b is made of a mixed foamed material of silicone rubber and azodicarbonamide (trade name Binhoi, manufactured by Eiwa Kasei) which is an organic foaming agent. The foaming agent is used to reduce the weight of the magnetic therapy device 1 and does not necessarily need to be mixed. The soft resin material 2b means both the case of being made of silicone rubber and the case of being made of a mixed foam obtained by mixing a foaming agent into silicone rubber.

  The magnet body 3 is formed of a so-called permanent magnet such as a ferrite magnet, a samarium / cobalt magnet, or a neodymium magnet in a substantially cylindrical shape. The magnet body 3 is fixed to the skin surface 1b side of the base portion 2 as shown in FIG. In the present embodiment, as shown in FIG. 5A, it is fixed at four equally spaced sides on the skin surface 1b. However, one or more magnet bodies 3 can be provided depending on the strength of the magnetic force. Of course, the arrangement of magnetic poles is not limited.

  The pressure-sensitive adhesive layer 4 is composed of an adhesive silicone gel and a highly water-absorbing polymer, and both the silicone gel and the highly water-absorbing polymer are exposed on the surface of the pressure-sensitive adhesive layer 4. For example, KE-1052A / B (manufactured by Shin-Etsu Chemical Co., Ltd.) or the like is adopted as the silicone gel, and Sunfresh ST-500N (manufactured by Sanyo Chemical Industries) or the like is adopted as the superabsorbent polymer. Since an adhesive including silicone is employed, it is hygienic and safe for the wearer, and itching, rash, and stuffiness can be eliminated. The highly water-absorbing polymer is used to improve water absorption and does not necessarily need to be mixed.

  As shown in FIG. 2A, the magnetic therapy device 1 composed of the base portion 2, the magnet body 3, and the adhesive layer 4 is formed as follows. First, a single flexible film 2a is placed in a curved mold for molding, and the magnet body 3 is placed thereon. Then, the silicone rubber and the organic foam material are mixed to form the soft resin material 2b and poured into the mold. After that, it is encapsulated with a separate flexible film 2a from above the soft resin material 2b to form a bag and heated at about 120 ° C. to 160 ° C. As a result, the silicone rubber is in a foamed state under the action of the organic foam material, and is molded as a lightweight base portion 2 entirely covered with the flexible film 2a. Thereby, since the magnet body 3 is embed | buried in the base part 2, there is no possibility of losing.

  Moreover, in order to arrange | position the magnet body 3 easily, you may provide a recessed part in a type | mold. In such a case, the flexible resin 2b is poured after the flexible film 2a is placed and the magnet body 3 is installed in the recess.

  Furthermore, unlike the manufacturing method described above, the magnet body 3 can also be installed inside the bag-like base portion 2. In such a case, the soft resin material 2b is enclosed in the bag-like flexible film 2a at the time of molding, and the magnet body 3 is also arranged and enclosed at the same time.

  Regardless of the manufacturing method, the magnet body 3 is disposed on the skin surface 1b side (adhesive layer 4 side described later) in the soft resin material 2b so as to contact the flexible film 2a. The When it is difficult to arrange the magnet bodies 3, a method of magnetizing the magnet bodies 3 after forming the base portion 2 is desirable.

  Next, an adhesive made of silicone gel is applied to the skin surface 1b side of the base portion 2 taken out from the mold. After the application, it is dried at a temperature of 10 ° C. to 80 ° C. and dried and cured, and the superabsorbent polymer is sprinkled almost uniformly on the silicone gel to form the adhesive layer 4. Of course, the superabsorbent polymer may not be provided on the entire surface on the skin surface 1b side.

  Further, in order to make the surface of the adhesive layer 4 smooth, the superabsorbent polymer is embossed into a silicone gel. The embossing step is not always necessary, and can be terminated by sprinkling the superabsorbent polymer on the silicone gel.

  In addition, about the soft resin material 2b of the base part 2 in the magnetic therapy apparatus 1 which concerns on this invention, it is not restricted to a silicone rubber, For example, various well-known elastomers, such as urethane and a polyester elastomer, can be used. .

  In addition, a highly water-absorbing polymer having a water absorption amount of about 50 to about 1000 times the weight of the highly water-absorbing polymer can be used. The balance with drainage after water absorption is very excellent, and when washing and drying are performed after use, water can be sufficiently removed and it can be extremely suitable for reuse. .

  The magnetic treatment device 1 molded in this way is used by directly sticking to the affected part where the wearer feels stiffness such as shoulders and waist with the adhesive layer 4. It can reduce or eliminate stiffness and muscle fatigue.

As described above, according to the magnetic therapy device 1 according to the present invention described above, since the soft resin material 2b is used in the base portion 2, the weight of the entire magnetic therapy device 1 can be reduced. Can be prevented from accidental dropout.
Further, since the base portion 2 is formed in a bag shape, the internal soft resin material 2b is not exposed, and can be used many times by washing the magnetic therapy device 1 with water or a neutral detergent. is there.
Furthermore, since both the silicone gel forming the adhesive layer 4 and the superabsorbent polymer are exposed, it is hygienic and safe for the wearer and can eliminate itching, rash, and stuffiness, and is appropriate. Adhesive strength at various positions can be ensured, so that it can be stably adhered for a long period of time. Moreover, since extremely excellent sweat absorption can be ensured, it is possible to prevent stuffiness due to sweat.
Moreover, since the base part 2 in the magnetic therapy device 1 is curved, it can be easily attached to any part of the body.

  In addition, when the flexible film 2a does not have air permeability, the ventilation is blocked by the base portion 2, and when the flexible film 2a has air permeability, the closed cell soft resin material 2b Ventilation will be blocked. Thereby, while avoiding contact with outside air, it is possible to prevent the propagation of various germs and to prevent the diffusion of body odor, and a comfortable feeling of use can be obtained due to the synergistic effect with the sweat absorbency by the highly water-absorbent polymer.

  Further, unlike the above manufacturing method, as shown in FIG. 2B, the magnet body 3 can be fixed to the base portion 2 in a state of protruding from the skin surface 1b. Specifically, after forming the lightweight base portion 2 covered with the flexible film 2a and before drying and curing, the magnet bodies 3 are arranged on the skin surface 1b side to form the adhesive layer 4 What is necessary is just to fix with the adhesive agent 5 different from an agent. Thereby, in the state which protruded from the skin surface 1b, the magnet body 3 can be adhere | attached on the base part 2, and it is effective when stimulating an acupuncture point.

  The magnet body 3 may be covered with a synthetic resin cover (not shown) made of urethane rubber or the like. Thereby, it can also prevent that the magnet body 3 contacts a body directly.

  Further, powdered germanium and zirconium having a particle size of about 0.4 μm can be mixed in the adhesive made of silicone gel when forming the pressure-sensitive adhesive layer 4. Thereby, stiffness, muscle fatigue, etc. can be reduced or eliminated by the synergistic effect of the three physical actions of magnetism, germanium anion and far-infrared ray in zirconium.
