Particularly in a high-frequency magnetic therapy device that requires a coil and a high-frequency current generator, miniaturization thereof is an important issue.

成してある。Hereinafter, the present invention will be described based on examples. FIG. 1 is an exploded perspective view showing an embodiment of the present invention. In the figure, 1 is a case body made of a non-magnetic material, 2 is a printed circuit board having a coil pattern 3 formed by etching, and is adhered to the case body 1. It is fixed by. Reference numeral 4 denotes a high-frequency oscillation integrated circuit mounted on the printed circuit board 1, which is a well-known oscillation circuit and generates a high-frequency current of about 10 MHz. A button battery 5 for power supply is mounted on the printed circuit board 1. The coil pattern 3, the high frequency oscillation integrated circuit 4 and the battery 5 are electrically connected to each other so that a high frequency current is supplied to the coil 3. Reference numeral 6 denotes a case cover made of paramagnetic material, which is formed by squeezing aluminum in this embodiment.

オ等にノイズが入るなど、電磁波障害が大きくなる。By the way, since the strength of the magnetic field by the coil is proportional to the current and the number of turns of the coil, in order to downsize the high-frequency magnetic therapy device, it is sufficient to increase the current flowing through the coil or increase the number of turns of the coil. Since increasing the current accelerates the consumption of the battery, it is effective to reduce the size of the printed circuit board 1 by etching the coil pattern 3 with a minute width and a large number of turns to increase the number of turns. As described above, although the magnetic effect is enhanced by increasing the number of turns and strengthening the magnetic field, electromagnetic waves emitted outside the skin surface also become large, and electromagnetic interference such as noise in the transistor radio increases.

μＡとした。Therefore, in the present invention, the portion other than the surface of the case that comes into contact with the body (the case cover 6 in the above embodiment) is made of a paramagnetic material such as aluminum to shield the magnetic lines of force other than the skin surface, and The magnetic field lines reach the surface deeply. This will be easily understood from the analysis results shown in FIG. Note that the above analysis example is based on the finite element method, and the coil is symmetric, so the analysis is performed in half. In this analysis, the case cover is made of aluminum with a diameter of 27 mm, the number of turns of the coil is 30 turns, and the high frequency current flowing in the coil is 10 MHz, 2
It was set to μA.
