Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a magnetic therapy device that can automatically perform acupressure on the skin and muscles while applying magnetic force to the human body using a magnetic body.

BACKGROUND ART FIGS. 7 and 8 are diagrams showing a conventional magnetic therapy device disclosed in, for example, Japanese Utility Model Application Publication No. 51-48388,
In the figure, 1 is a spherical magnet, and one part has a flat surface 1a.
have. 2 is an adhesive paper to which the magnet 1 is attached with its flat surface 1a.

When this is applied in close contact with acupressure points on the human body, the spherical part of the magnet 1 presses against the skin due to the activity of the skin and muscles, softening the muscles, improving blood circulation, and promoting recovery from fatigue. At this time, the effect of the magnetic action of the magnet body 1 is also synergistically exhibited.

Problems that the invention aims to solve In the conventional magnetic therapy device as described above, the magnet body 1
is fixed to the adhesive paper 2, the pressing force by the magnet 1 is small, and a problem arises in that a large acupressure effect cannot be obtained.

This invention was made to solve this problem, and the purpose is to provide a magnetic therapy device that can enhance the acupressure effect and exhibit great therapeutic effects.

Means for Solving the Problems The magnetic therapy device according to this invention has an adhesive piece bonded to the magnetic body so that at least the pressing surface side of the magnetic body can be moved in the pressing direction using a shape memory alloy.

Function: When applied to the human body, the shape memory alloy stretches and deforms due to body temperature, causing at least the pressing surface side of the magnetic body to move from the adhesive piece in the pressing direction, so that the pressing surface side of the magnetic body bites into the skin. included,
A large pressing force is applied.

Embodiment of the invention Figures 1 to 3 show an embodiment of the invention, in which 3 is a magnetic body consisting of two hemispherical metal magnetic bodies 3a and 3b having magnetic properties, and 4 is a magnetic body consisting of two hemispherical metal magnetic bodies 3a and 3b. An S-shaped shape memory alloy whose both ends are fixed to both metal magnetic bodies 3a and 3b respectively and constitutes a substantially spherical magnetic body 3; 5 is an adhesive piece having an adhesive layer 6 on one side;
It is made of film (acetate, polyester, polyethylene), raw cloth (woven fabric), metal foil, etc., and the adhesive side magnetic body 3b is attached to the adhesive layer 6.

When this is attached to the human body using the adhesive piece 5, the pressing surface 301 of the pressing surface side magnetic material 3a presses the skin, and at the same time, a magnetic force is generated from the magnetic material 3 to the human body. When the shape memory alloy 4 is elongated and deformed by body temperature as shown in FIG. 3, the pressing surface 301 of the pressing surface side magnetic body 3a digs into the skin, and a large pressing force is applied.

4 to 6 show other embodiments of this invention, in which 7 is a coil spring-like coil whose ends are fixed to both metal magnetic bodies 3a and 3b, respectively, constituting a substantially spherical magnetic body 3. It is a shape memory alloy.
The rest of the structure is the same as that of the embodiment shown in FIGS. 1 to 3, so the explanation will be omitted.

When this is attached to a human body using the adhesive piece 5, the pressing surface 301 of the pressing surface side magnetic body 3a presses the skin. When the shape memory alloy 7 is elongated and deformed by body temperature as shown in FIG. 6, the pressing surface 301 of the pressing surface side magnetic body 3a digs into the skin, and a large pressing force is applied.

In the above example, the shape memory alloys 4 and 7 were shown to stretch and deform due to body temperature, but for example, it could be made to stretch and deform when the temperature exceeds 30°C, or it could be made to stretch and deform at low temperatures so that it can be used even in cold regions. For example, it may be kept in the refrigerator at all times.

Further, in each of the above embodiments, if the dimensions of the magnetic bodies 3a and 3b are increased to 15 mm to 25 mm in diameter, an even greater acupressure effect can be obtained. This magnetic body 3a, 3
The shape of b, the shape of shape memory alloys 4 and 7, and the adhesive piece 5
Needless to say, the shape, material, etc. are not limited to those in each of the above embodiments. In addition, the magnetic body 3 is half body 3
Instead of using a and 3b, it is also possible to use one piece and press it with a shape memory alloy as in the conventional case.

Furthermore, in each of the above embodiments, if the adhesive piece 5 is disposable, the magnetic body 3 side can be used semi-permanently.

Effects of the invention As described above, this invention has the effect of providing a large therapeutic effect because the acupressure effect of the magnetic body can be enhanced by deformation due to the elongation of the shape memory alloy.
