Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for increasing the penetration amount of magnetic field line pulses in order to obtain a strong magnetic flux density even at a distance from a magnetic field line generation coil when performing magnetic therapy using magnetic field lines. B. The coils for generating lines of magnetic force are arranged in tandem in the same direction so that the lines of magnetic force pass through each coil for generating lines of magnetic force, thereby reducing leakage and demagnetization flux to the outside of the coil for generating lines of magnetic force, and The purpose is to increase the lines of magnetic force generated in the inner diameter direction.

That is, the present invention connects a plurality of magnetic force line generation coils in series or in parallel to a magnetic force line generation pulse transmitter, and arranges the magnetic force line generation coils so that the magnetic force lines generated pass through them in the same direction. The gist of the present invention is the structure of a device for increasing the amount of penetration of magnetic field pulses.

When a current is passed through the coil for generating lines of magnetic force, as shown in Fig. 1, the lines of magnetic force F become almost circular leakage magnetic flux except those that pass through the center line of the coil for generating lines of magnetic force L, and leave the coil L for generating lines of magnetic force. Accordingly, the lines of magnetic force decrease significantly.

In other words, as shown in Figure 2, if the vertical axis represents the magnetic intensity and the horizontal axis represents the distance from the magnetic force-generating coil surface with radius r as a reference, then the point is a point that is the radius away from the magnetic field line generating coil surface. The magnetic strength at point b is about 1/2, and at a point a diameter away, the magnetic strength at b is less than 1/8.

FIG. 3 shows the state of the lines of magnetic force F when the two coils L1 and 2 for generating lines of magnetic force are arranged with a distance equal to their diameters apart. In this case, the lines of magnetic force F are almost parallel within the coil diameter between the coils LI L2 for generating lines of magnetic force, and the leakage magnetic flux to the outside is extremely small. As shown in Fig. 4, the magnetic intensity at this time reaches its maximum value when the distance O is close to one of the magnetic field line generating coils Ll, and decreases only slightly when the distance is away by the radius. , when it approaches the other magnetic field line generating coil L2, it becomes the maximum value again.

In this way, when two coils for generating magnetic lines of force are arranged along the center line and an object is placed between the coils for generating lines of magnetic force, the lines of magnetic force are formed inside the object in the form of almost parallel magnetic lines of force. This makes it possible to supply a strong magnetic flux density to the target object.

Figure 5 shows three magnetic field line generation coils LI L2 La
are arranged in parallel, and the lines of magnetic force F pass through the coil for generating lines of magnetic force as almost parallel lines as shown in the figure.

In the case of using two coils for generating magnetic lines of force as shown in Fig. 3, a current for magnetic therapy is passed through the two coils for generating lines of magnetic force so that magnetic flux is generated in the same direction at the same time. By placing your body between them, almost parallel lines of magnetic force will penetrate inside your body.

As shown in Figure 5, when three coils for generating magnetic lines of force are arranged in the direction of the center line, treatment can be performed simultaneously by placing both hands or both feet between the coils for generating lines of magnetic force. .

The wiring diagram in Figure 6 shows two magnetic field line generation coils LIL2.
The wiring diagram in Fig. 7 shows a state in which three magnetic field line generating coils L+ L2 La are connected in parallel to the magnetic field line generating pulse transmitting device A. The connected state is shown, and an appropriate device can be adopted as the pulse transmitter A for generating magnetic lines of force, and an appropriate connection can be adopted depending on the voltage and current capacity of the power source.

Figures 8 to 10 show the waveforms of the current flowing through the magnetic field line generating coil, unipolar pulse current as shown in Figure 8, or biphasic action potential waveform pulses as shown in Figure 9. Any current, or even rectangular wave current as shown in FIG. 10, may be arbitrarily employed.
