Description

[Detailed Description of the Invention] <Technical Field of the Invention> This invention relates to a magnetic field generating therapeutic device that applies magnetic lines of force to the human body to increase blood circulation and alleviate various symptoms such as stiffness.

<Background of the invention> Conventionally, as this type of treatment device, one has been proposed in which an alternating magnetic field generator is built into a case body, and the alternating magnetic field is applied to an affected area such as a stiffness to apply an alternating magnetic field to the human body. However, in the case of this type of device, the magnetic field lines only act on one part of the human body, so if the affected area is spread over a wide area, the therapeutic effect is extremely weak. Moreover, in order to treat a wide area of the affected area, it is necessary to move the instrument sequentially along the surface of the human body, which poses problems such as requiring laborious operations and increasing the time required for treatment.

Therefore, a structure was proposed in which multiple magnetic field generators were pivotally connected in a row using hinges to enable treatment over a wide range of areas.
No. 13303). However, although this treatment device is convenient for wrapping around arms and legs, it is not suitable for treating areas that extend two-dimensionally, such as the back, because it is arranged in a one-dimensional manner. Moving the equipment is still required. Furthermore, since ordinary hinges are used to connect the magnetic field generators, there is a problem in that the connection is not easy and requires a lot of effort.

<Purpose of the invention> The object of this invention is to provide a magnetic field generating treatment device that enables magnetic treatment over a wide range without moving the device and has a structure that is extremely easy to assemble and connect.

<Structure and Effects of the Invention> In order to achieve the above object, in this invention, a plurality of case bodies each containing a built-in magnetic field generator that generates an alternating magnetic field are arranged in an equal array vertically and horizontally to form a magnetic field generating treatment device.

Each case body is formed by butting the opening surfaces of the upper and lower cases, which have a symmetrical shape, and the opposing sides of the adjacent case bodies to be connected are provided with connection pieces protruding from the sides of the upper and lower cases. A connecting portion formed by overlapping is integrally formed, and each connecting piece has a half-shaft portion that forms a shaft body when the cases are stacked, and protrudes in opposite directions along the side surface.

Then, the connecting parts of the case bodies to be connected are pivotally connected by a vertically split connecting tool having a bearing part into which each shaft body is rotatably fitted, thereby integrating the case bodies in a flexible manner. .

According to this invention, each case body, which is connected vertically and horizontally, can be bent and deformed freely to adapt to the surface shape of the human body, so that magnetic lines of force can be applied over a wide range and effectively on the human body. . Therefore, even if the affected area is a two-dimensionally expanding area such as the back, magnetic treatment can be performed reliably and in a short time without moving the instrument and keeping it fixed.

In addition, the number of connections can be freely set, and it can be used alone or incorporated into equipment such as chairs and beds, making the range of application extremely wide.

Furthermore, since the shaft body is integrally formed in the case body, and each shaft body of the case body to be connected is pivotally connected using a connecting tool, it is compared to the conventional example in which a normal hinge is used to connect the magnetic field generator. Therefore, the connection work is easy.

Furthermore, the connecting tool has a vertically divided structure, and the case body is formed by butting the upper and lower cases together, and each upper and lower case has a half-shaft portion that forms the shaft body by overlapping, so that it is easy to assemble the case body. It has many practical effects, such as being able to simultaneously achieve fixation and connection between the case bodies, and efficiently perform the assembly and connection operations of the case bodies.

A capacitor 8 is interposed between the capacitor d and the capacitor 8. This capacitor 8 is used to ensure that the current flowing through the coils 20c and 20d is out of phase by 90 degrees with respect to the current flowing through the coils 20a and 20b. By reversing the winding directions between the coils 20c and 20d, as shown in FIG. It has been done.
