[Action]

 In the pulsed electromagnetic hyperthermia treatment device having the above-mentioned configuration, the pulsed electromagnetic field generator can be arranged in close contact with the affected part of the human body together with the vibration generator arranged in the central void. When the pulse current generator is operated in that state, a pulse electromagnetic field is generated in the central portion of the pulse electromagnetic field generator in a direction perpendicular to its main surface, and this electromagnetic field effectively acts on the affected area. Further, in the present invention, since the pulse electromagnetic field generator is formed by vertically stacking and integrating a plurality of planar coils formed by spirally winding an insulated wire, A strong pulsed electromagnetic field is generated and much heat is generated. Further, the fluctuating electromagnetic field thus generated causes a slight vibration in the permanent magnet of the vibration generator and the indicator lamp is turned on.

Therefore, in the affected part of the human body, in addition to the electrochemical action and the thermal action due to the magnetism of the pulsed electromagnetic field, the massage action due to the vibration of the permanent magnets acts, the stiffness of the muscle is positively removed, and the blood circulation is positively affected. Is promoted. Further, since the lighting brightness of the display lamp changes in proportion to the strength of the pulse electromagnetic field, the generation and strength of the electromagnetic field can be visually confirmed by the brightness of the display lamp.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram schematically showing the entire embodiment of the pulse electromagnetic hyperthermia device of the present invention. In this figure, reference numeral 1 is a pulse current generator, 2 is a plate-shaped pulse electromagnetic field generator electrically connected to the pulse current generator 1 by a conductor 3, and 4 is a vibration generator.

As shown in FIG. 2, the pulse current generator 1 includes a voltage variable circuit 5, an inverter circuit including a step-up transformer 6 and a conversion control circuit 7, a rectifier circuit 8 and a filter 9. The inverter circuit converts the DC current input from either the step-down rectifier circuit for AC power supply or the battery circuit into an AC current of 40 to 100 KHz at a voltage up to 10 times the power supply voltage, and the rectifier circuit 8 converts it. A linear converter 10 for converting into a DC current, a high-voltage charging / discharging unit 11 and a high-voltage switch 12 connected to the linear converter 10, and a trigger generation circuit 13 for driving the high-voltage switch 12 are provided. Then, the direct current output from the linear converter 10 is charged in the high voltage charging / discharging unit 11, and is supplied as a pulse current to the pulse electromagnetic field generator 2 by the high voltage switch 12 driven by the trigger generating circuit 13. Has been done.

In the pulse electromagnetic field generator 2, as shown in FIG. 3, two layers of the planar coil 15 formed by spirally winding the insulated wire 14 are vertically stacked, and the insulated wire 14 is The upper and lower windings are bonded and integrated. The upper and lower two-layer planar coils 15 are connected in series, and the end of the insulated wire 14 of each layer is connected to the conductor 3. A sheet 16 made of plastic is laid on the main surface (upper surface) of one side of such a coil laminate, and the planar coil 15 and the vibration generator in the upper layer are fused to the sheet 16. ing. Further, a nonwoven fabric sheet 17 having cushioning properties and heat insulating properties is overlapped and sewn on the main surface on the opposite side of such a coil laminated body, and the whole is housed in a cover case (not shown). Has been done.

Further, as shown in FIG. 4, the vibration generator 4 has a vibrating body 20 in which a permanent magnet piece 18 is covered with a foam plastic 19, and a magnetic thin plate 21 is magnetically attached to one end of the metal piece. A display unit having a coil 22 formed by winding a copper wire around the other end, and a display lamp 23 connected to both ends of the copper wire, and a display lamp with a current induced in the coil 22 by a pulse varying electromagnetic field. 23 is configured to light up. Then, the vibrating body 20 is housed in the void in the center of the pulse electromagnetic field generator 2, and the magnetic thin plate 21 is attracted by the magnetic force of the permanent magnet pieces 18 constituting the vibrating body 20 so that the display portion is made of plastic. It is seated against the vibrating body 20 through the seat 16 and the cover case.

In the pulse electromagnetic hyperthermia treatment apparatus of the embodiment configured as described above, since the pulse electromagnetic field generator 2 has a flat plate shape with almost no thickness, it is arranged in the central space thereof. Together with the vibration generator 4, it can be placed close to the affected part of the human body. Then, when the pulse current generator 1 is operated, the electric charge stored in the high voltage charging / discharging unit 11 is intermittently discharged to the pulse electromagnetic field generator 2 and the central portion thereof is pulsed in the direction perpendicular to the main surface. Since a field is generated, the electrochemical action of the magnetic field can be effectively exerted on the affected area. In addition, since the linear converter 10 is used for the pulse current generator 1, it is possible to apply an arbitrary output voltage to the pulse electromagnetic field generator 2 and the variable range up to 10 times the power supply voltage can be set by the inverter circuit. Since a high voltage can be applied, the heating effect of the heat generated by the planar coil 15 can be expected. Furthermore, it does not require a large-capacity, heavy-weight power transformer, and can be used as a portable device. Furthermore, since the fluctuating electromagnetic field generated by the pulse electromagnetic field generator 2 causes vibrations in the permanent magnet pieces 18 of the vibrating body 20 disposed in the space, the vibration mechanically massages the affected area. , Muscle stiffness is positively removed and blood circulation is promoted. Further, since the indicator lamp 23 is lit by the pulsed electromagnetic field and its brightness changes in proportion to the strength of the magnetic field, not only the treatment person himself but also another person varies depending on the brightness of the indicator lamp 23. The generation and strength of the field can be easily determined. Further, since the vibrating body 20 is covered by the cover case, it is difficult to see the position where the vibrating body is arranged from the outside. However, since the display lamp 23 is provided in confrontation therewith, the vibrating body 20 is provided by the display lamp 23. 20 can be positioned, and this can be accurately applied to the acupoint of the affected area.
