Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the device described in Patent Document 1, since the high-frequency coil and the low-frequency coil are housed in the casing together with the transmission circuit and the battery, in order to irradiate the affected part with the magnetic field generated by these coils, it is necessary to apply the casing to the affected part. There were inconveniences such as the casing being bulky and getting in the way, or getting caught on clothing and falling off the affected part.

[0006] And in order to solve this problem, if the casing is made smaller, it is necessary to make the transmission circuit and the battery smaller as well, and it has been found that this causes a new problem that sufficient magnetic field strength and operating time cannot be obtained.

[0007] The probe of the magnetic therapy device needs to be in contact with the affected part of the human body, such as the arm or leg, and be deformed to follow it, and it also needs to be designed so that it can be manufactured with a good yield during the manufacturing process.

[0008] The present invention has been made in view of such circumstances, and an object thereof is to provide a magnetic therapy device having a high magnetic therapy effect and capable of appropriately following the affected part.

Means for Solving the Problems

[0009] The magnetic therapy device according to the present invention that advantageously solves the above problems is a magnetic therapy device that generates a signal wave for biological stimulation, irradiates the affected part of the living body with a magnetic field for stimulating the affected part generated in a coil by the signal wave for biological stimulation, and treats the pain of the affected part by stimulating the cells and nerves in the affected part and the periphery of the affected part. It is a device having a signal wave output unit that generates and outputs signal waves for biological stimulation of a plurality of frequencies, and a probe formed separately from the device body, which is connected to the signal wave output unit by a signal cable and has one coil that outputs the first frequency and the other coil that outputs the second frequency, each of which is supplied with the signal wave for biological stimulation output from the signal wave output unit. The one coil and the other coil are formed as planar bodies on both sides of an insulating flexible thin plate, and the flexible thin plate between the one coil and the other coil is provided with slits separated by a plurality of crosslinks.

Effects of the Invention

[0010] In the magnetic therapy device of the present invention, a signal wave output unit provided in the device main body generates and outputs biological stimulation signal waves of a plurality of frequencies. A coil that outputs a first frequency and another coil that outputs a second frequency, which are provided in a probe formed separately from the device main body, are connected to the signal wave output unit by a signal cable and supplied with the biological stimulation signal waves output from the signal wave generation unit, and an alternating magnetic field for stimulating the affected area is generated by the signal waves of the first frequency and the second frequency for biological stimulation.

[0011] Therefore, according to the magnetic therapy device of the present invention, by applying a probe separate from the device main body to the affected area of the living body, the high-frequency alternating magnetic field generated by one coil for high-frequency output, for example, the first frequency, is irradiated to the affected area to stimulate the cells of the affected area, and by this stimulation, for example, the damaged nerves in the affected area can be activated and self-repaired, and it is expected to reduce the nerve disorder in the affected area. In addition, the stimulation given by irradiating the affected area with the low-frequency alternating magnetic field for stimulating the affected area generated by another coil for low-frequency output, for example, the second frequency, reaches the brain (sensory area) from the posterior horn of the spinal cord along the sensory nerve (Aβ fiber: touch sense), so it is expected that the brain will recognize the pleasure of touch and activate the descending pain inhibitory system to bring about an analgesic effect and a relaxation effect.

[0012] Moreover, according to the magnetic therapy device of the present invention, since a slit is provided in the insulating flexible thin plate in the probe in which the coil is formed, the probe can be easily deformed and can be appropriately adapted to the affected area. In addition, since the slit of the flexible thin plate is divided by a plurality of crosslinks, the flexible thin plate does not protrude even when resin molding is used during the molding of the probe, and it can be manufactured with good yield.

[0013] In the magnetic therapy device of the present invention, when the probe is a substantially quadrilateral flat plate and the side length as a quadrilateral is in the range of 25 to 75 mm, it is easy to attach to a human limb with tape or the like. For example, if it is an arm, it can be wrapped around about half a circumference, so the treatment effect is enhanced, which is preferable.

Embodiments for Carrying out the Invention

[0015] Hereinafter, embodiments of the present invention will be specifically described. Note that the drawings are schematic and may be different from the actual ones. Also, the following embodiments illustrate methods for embodying the technical idea of the present invention and do not specify the configuration to be the following. That is, the technical idea of the present invention can be variously modified within the technical scope described in the claims.

[0016] An overall conceptual diagram of a magnetic therapy device according to an embodiment of the present invention is shown in FIG. 1. In the following figures, reference numeral 1 indicates the device main body included in the magnetic therapy device of this embodiment, reference numeral 11 indicates the probe, and reference numeral 21 indicates the signal cable. Also, it is provided with a power cable (not shown) that is detachably inserted and mounted on the device main body 1.

[0017] The device main body 1 of the magnetic therapy device of this embodiment includes a resin casing 2, a touch panel type display 3 that is obliquely upwardly accommodated in the front part within the casing 2 and exposed from the opening on the front surface of the casing 2, a signal wave output part accommodated in the upper side of the rear part within the casing 2, and a power supply part accommodated in the lower side of the rear part within the casing 2. Note that an alarm stop button and a power switch button are provided on the left and right of the lower side of the opening on the front surface of the casing 2 of the device main body 1. And further below those buttons, three sockets for plugs of the signal cable 21 are provided side by side in order to enable connection of three probes 11 to the device main body 1.

[0018] Figure 2 is a top view (a), a rear view (b), and an A-A cross-sectional view (c) of the probe 11 of the magnetic therapy device of this embodiment. In this embodiment, the probe 11 has an outer casing 12 made of a flexible material in a substantially quadrilateral shape, and a circuit part 13 raised in a frustum of a pyramid shape for the purpose of protecting an electric circuit or the like. The signal cable 21 is drawn out from the back of the circuit part.

[0019] As shown in Figure 2(c), the probe 11 houses a flexible thin plate 14, which is a printed circuit board on which a coil and an electric circuit are arranged, within an outer casing 12 made of a soft resin such as an elastomer or a rubber material. The probe 11 can be manufactured by resin molding such as injection molding or RIM molding. Since resin molding is accompanied by self-heating, it is preferable to pre-apply a resin mold to the circuit part 13 for the purpose of protecting an electric circuit or the like.

[0020] FIG. 3 is a printed wiring diagram showing the coil arrangement of the magnetic therapy device of this embodiment, and represents a top view (a) and a bottom view (b). On the printed circuit board 14, a circuit section 13, a high-frequency output coil 15 as one coil that outputs a first frequency, a magnetic field strength detection coil 16, a low-frequency output coil 17 as another coil that outputs a second frequency, etc. are arranged. In this embodiment, on the upper surface of the printed circuit board 14, the high-frequency output coil 15 is formed as an annular disk, and the magnetic field strength detection coil 16 is formed as an annular shape outside it and arranged. Also, a spiral low-frequency output coil 17 is arranged inside the high-frequency output coil 15. The high-frequency output coil 15 and the low-frequency output coil 17 are also arranged on the lower surface of the printed circuit board 14, and are configured symmetrically with respect to the surface so that high-frequency current and low-frequency current flow in the same direction on both the upper and lower surfaces. By doing so, the centers of the magnetic fields generated by the coils on both the upper and lower surfaces can be made to coincide. A slit portion 18 is provided between the high-frequency output coil 15 and the low-frequency output coil on the printed circuit board 14, facilitating the follow-up of the printed circuit board 14 when the probe 11 is deformed. Also, a plurality of locations on the circumference of the slit portion 18 are bridged and connected by bridge portions 19, enabling stable molding without a part of the printed circuit board deforming and protruding or being exposed when the printed circuit board 14 is covered with resin molding. Note that the high-frequency output coil 15, the magnetic field strength detection coil 16, and the low-frequency output coil 17 may be changed to a rectangular shape instead of an annular shape.

[0021] The probe 11 is preferably made into a substantially quadrilateral shape, particularly a substantially rectangular flat plate, which is easy to attach to the limbs of a person who is the affected part and easy to fix with tape. When the sides W and L of the probe 11 as a quadrilateral are in the range of 25 to 75 mm, for example, it is possible to run along about half the circumference of the arm, so the therapeutic effect is high. Also, the thickness t is preferably in the range of 0.2 to 5 mm. The lower limit of the thickness is preferably determined from the insulation of the wiring on the printed circuit board and the lifespan considering the wear of the probe. The upper limit of the thickness is preferably determined so that it can be moderately deformed manually.

[0022] The flexible thin plate 14 is a film-like printed circuit board, preferably having a base layer made of a film of a flexible insulating material and, if necessary, an adhesive layer. The base layer can use polyimide resin, polyester resin, polyamide paper base epoxy resin, glass cloth base epoxy resin, glass base BT resin, etc. Each coil can be printed on the printed circuit board 14 such as a metal foil, or can be an etched conductor. The thickness of the printed circuit board 14 is preferably about 0.1 mm. The conductor constituting the coil is preferably about 12 to 70 μm, for example, as a copper foil. If it is less than the lower limit, the electrical resistance of the coil becomes too large, and there is a risk that heat generation becomes a problem. If it exceeds the upper limit, when the probe 11 is deformed, the deformation of the copper foil cannot follow, and there is a risk of peeling from the printed circuit board or disconnection.

[0023] As the first frequency, the frequency of the high-frequency current flowing through the high-frequency output coil is 100 MHz or more and about 400 MHz, and the frequency is changed continuously or at a predetermined time interval to prevent the affected area from getting used to the stimulation signal. Preferably, it is in the range of 200 MHz to 300 MHz.

[0024] As the second frequency, the frequency of the low-frequency current flowing through the low-frequency output coil is 1 kHz or more and about 3 kHz. It is preferable that the center of the magnetic field generated by the high-frequency output coil coincides with the center of the magnetic field generated by the low-frequency output coil. By doing so, it becomes possible to supply the low-frequency magnetic field to the affected area by superimposing it on the high-frequency magnetic field, and the magnetic therapy effect is enhanced.

[0025] In the magnetic therapy device of this embodiment, the device main body 1 functionally includes a signal wave output unit, a screen control unit, and a power supply unit. The signal wave output unit in this embodiment is circuit-configured using a plurality of central processing units (CPUs), generates a basic high-frequency signal of 100 MHz or more by a basic high-frequency signal generation unit, and the basic high-frequency signal shift unit shifts the basic high-frequency signal, for example, with a center frequency of 250 MHz, within a range from 225 MHz to 275 MHz, which is ±10% of it, while excluding the frequency band used in aircraft emergency radios, and moderately shifts (varies) it, for example, every 0.00014 seconds (i.e., about 7000 times / second) as a fixed time, and outputs the shifted basic high-frequency signal to the basic high-frequency signal frequency modulation unit.

[0026] The signal wave output unit also reads out from the SD card or the like a magnetic signal pattern including a sound source signal such as music, which is pre-recorded in an external storage device such as an SD card mounted on a card slot or a built-in storage device, by a magnetic signal pattern reading unit, and supplies it to a low-frequency signal generation unit for biological stimulation. The low-frequency signal generation unit for biological stimulation generates a low-frequency signal for biological stimulation from the frequency information of the magnetic signal pattern (for example, 1 kHz or more and 3 kHz or less), and outputs the low-frequency signal for biological stimulation to the basic high-frequency signal frequency modulation unit.

[0027] Then, the basic high-frequency signal frequency modulation unit frequency-modulates the basic high-frequency signal of, for example, 250 MHz ± 10%, which is generated by the basic high-frequency signal generation unit and frequency-shifted by the basic high-frequency signal shift unit, with the low-frequency signal for biological stimulation of, for example, 1 kHz or more and 3 kHz or less, which is generated by the low-frequency signal generation unit for biological stimulation, and supplies it to the high-frequency signal output unit for biological stimulation. The high-frequency signal output unit for biological stimulation amplifies and outputs the frequency-modulated high-frequency signal for biological stimulation. Note that the high-frequency signal output unit for biological stimulation may amplify and output the frequency-modulated high-frequency signal for biological stimulation after amplitude-modulating it with the above-mentioned low-frequency signal for biological stimulation. Also, the low-frequency signal output unit for biological stimulation amplifies and outputs the low-frequency signal for biological stimulation of, for example, 1 kHz or more and 3 kHz or less, which is generated by the low-frequency signal generation unit for biological stimulation. These operations in the signal wave output unit are controlled by the operation state control unit.

[0028] In this embodiment, the probe 11 houses a flexible printed wiring board 14. On the flexible printed wiring board 14, there are printed wirings. A high-frequency output coil 15 is formed on the outside, and a low-frequency output coil 17 is formed on the inside. In addition, a magnetic field strength detection coil 16 is formed outside the high-frequency output coil 15. Further, an operation state detection unit is circuit-configured using a temperature detection element and a CPU mounted on the flexible printed wiring board 14. The high-frequency output coil 15 generates a high-frequency alternating magnetic field for stimulating the affected area with a high-frequency signal for biological stimulation supplied from the high-frequency signal output unit for biological stimulation via the signal cable 21. The low-frequency output coil 17 generates a low-frequency alternating magnetic field for stimulating the affected area with a low-frequency signal for biological stimulation supplied from the low-frequency signal output unit for biological stimulation via the signal cable 21.

[0029] Then, the operation state detection unit detects the operation state of the signal wave output unit from the temperatures of the high-frequency output coil 15 and the low-frequency output coil 17 detected by the temperature detection element and the magnetic field strength of high frequency or low frequency detected by the magnetic field strength detection coil 16, and inputs a signal indicating the operation state to the operation state monitoring unit of the signal wave output unit via the signal cable 21. Based on the signal indicating the operation state, the operation state monitoring unit monitors the operations such as signal wave generation and output of the signal wave output unit, and thus the levels of the alternating magnetic fields generated by the high-frequency output coil 15 and the low-frequency output coil 17. When an abnormality is detected, an alarm control unit outputs an alarm signal (for example, the sounding of an alarm sound by a speaker (not shown) built in the apparatus main body 1, the display of an alarm message on the display 3, etc.). Note that the sounding of this alarm sound is stopped by operating the alarm stop button on the front of the casing of the apparatus main body 1. Also, immediately when an abnormality is detected, the operation state control unit stops the supply of the high-frequency signal for biological stimulation from the high-frequency signal output unit to the high-frequency output coil 15 and the supply of the low-frequency signal for biological stimulation from the low-frequency signal output unit for biological stimulation to the low-frequency output coil 17 in order to ensure the safety of the user of the magnetic therapy apparatus.

[0030] The screen control unit in this embodiment is configured as a circuit using a graphics processing unit (GPU) or the like. In the image display unit, screen information such as instruction buttons to be displayed on a liquid crystal display (LCD) of the touch input type display 3 previously recorded in an external storage device such as an SD card mounted in a card slot or the like is read from the SD card or the like and displayed on the LCD or the like. Further, in the instruction input unit, the position where the finger of the user of the magnetic therapy device touches the touch panel of the touch input type display 3 is detected from the change in static electricity or the like at that position, and a signal indicating the instruction input by the operation button displayed on the LCD or the like corresponding to the touch position is sent to the operation state control unit. Based on the signal indicating this instruction input, the operation state control unit controls the operations such as signal wave generation and output of the signal wave output unit, and thus the alternating magnetic field or the like generated by the high-frequency output coil 15 and the low-frequency output coil 17 according to the user's instruction.

[0031] The screen control unit also creates a log recording the instruction input to the instruction input unit by the operation button displayed on the LCD or the like and the operation state of the signal wave output unit at that time, and stores the information of the log in a USB memory (not shown) detachably mounted from the upper surface side in a USB memory slot in the protruding portion on the lower side of the rear part of the casing 2. Further, the image display unit has a clock function for displaying a clock on the LCD or the like, and maintains the clock function with a button battery mounted in the battery holder.

[0032] The power supply unit in this embodiment is configured as a circuit by a CPU (not shown) and two AC-DC converters. Then, a 100V commercial AC power supply supplied via a power cable (not shown) is used by the two AC-DC converters to obtain a predetermined DC power supply, and the charging voltage of the battery is obtained by connecting these DC power supplies in series to charge the battery. At the same time, a predetermined DC power supply stepped down from these DC power supplies by a switching power supply and a linear regulator is supplied as a DC power supply with the required voltage to the signal wave output unit and the screen control unit of the apparatus main body 1 and the operation state detection unit of the probe 11, respectively.

[0033] When the power supply unit is in normal use of the magnetic therapy device without the power cable attached, it steps down the DC power from the battery to the necessary DC voltages for the signal wave output unit and the screen control unit of the device body 1 and the operation state detection unit of the probe 11 using a switching power supply and a linear regulator respectively, and supplies the power, enabling the magnetic therapy device to be portable and used.

[0034] In the magnetic therapy device of this embodiment, the basic high-frequency signal generation unit, the basic high-frequency signal shift unit, and the basic high-frequency signal frequency modulation unit of the signal wave output unit of the device body 1 generate a high-frequency signal for biological stimulation, and the high-frequency signal output unit for biological stimulation outputs it. The high-frequency output coil 15 of the probe 11 formed separately from the device body 1 is connected to the high-frequency signal output unit for biological stimulation of the signal wave output unit by the signal cable 21, and is supplied with a high-frequency signal for biological stimulation having, for example, a center frequency of 250 MHz output from the high-frequency signal output unit for biological stimulation, and a high-frequency alternating magnetic field for stimulating the affected area is generated by the high-frequency signal for biological stimulation.

[0035] Therefore, according to the magnetic therapy device of this embodiment, by applying the probe 11 separate from the device body 1 to the affected area of the living body, the high-frequency alternating magnetic field generated by the high-frequency output coil 15 irradiates the affected area to stimulate the cells of the affected area. By this stimulation, for example, the damaged sensory cells in the affected area can be activated to induce neurotrophic factors, and it is expected to reduce the nerve disorder in the affected area. Since the high-frequency alternating magnetic field of 250 MHz at its center has a high effect of activating the damaged sensory cells and inducing neurotrophic factors, it is expected to enhance the effect of reducing the nerve disorder in the affected area.

[0036] Furthermore, according to the magnetic therapy device of this embodiment, the low-frequency signal generation unit for biological stimulation in the signal wave output unit of the device main body 1 generates a low-frequency signal for biological stimulation from the frequency information of the magnetic signal pattern (for example, 1 KHz or more and 3 KHz or less), the low-frequency signal output unit for biological stimulation outputs the low-frequency signal for biological stimulation, and the low-frequency output coil 17 of the probe 11 is connected to the low-frequency signal output unit for biological stimulation of the signal wave output unit by the signal cable 21 and is supplied with the low-frequency signal for biological stimulation from the low-frequency signal output unit for biological stimulation. Therefore, the stimulation applied by irradiating the affected part with the low-frequency alternating magnetic field for stimulating the affected part generated by the low-frequency output coil 17 by the low-frequency signal for biological stimulation reaches the brain (sensory area) from the posterior horn of the spinal cord through the sensory nerve (Aβ fiber: touch sense). Thus, it is expected that the brain recognizes the pleasantness of the touch sense and activates the descending pain inhibitory system to bring about an analgesic effect and a relaxation effect.

[0037] Furthermore, according to the magnetic therapy device of this embodiment, the basic high-frequency signal modulation unit of the signal wave output unit 13 of the device main body 1 frequency-modulates the basic high-frequency signal with the low-frequency signal for biological stimulation generated by the signal wave output unit to generate a high-frequency signal for biological stimulation, and the high-frequency signal output unit for biological stimulation supplies the frequency-modulated high-frequency signal for biological stimulation to the high-frequency output coil 15 of the probe 11. Therefore, by stimulating the cells of the affected part with the high-frequency alternating magnetic field for stimulating the affected part generated by the high-frequency output coil 15 by the high-frequency signal for biological stimulation frequency-modulated with the low-frequency signal for biological stimulation, it is expected that the damaged sensory cells of the affected part are activated more than in the case without frequency modulation, more neurotrophic factors are induced, and the nerve disorder of the affected part is more alleviated.

[0038] Furthermore, according to the magnetic therapy device of this embodiment, the signal wave output unit of the device main body 1 generates and outputs a low-frequency signal for biological stimulation. The probe 11 is connected to the signal wave output unit by a signal cable 21 and has a low-frequency output coil 17 that is supplied with the low-frequency signal for biological stimulation from the signal wave output unit. The signal wave output unit frequency-modulates a basic high-frequency signal with the low-frequency signal for biological stimulation to generate a high-frequency signal for biological stimulation and outputs it separately from the low-frequency signal for biological stimulation. Therefore, the low-frequency alternating magnetic field for stimulating the affected part generated by the low-frequency output coil 17 with the low-frequency signal for biological stimulation brings about an analgesic effect and a relaxation effect, and it is expected that the high-frequency alternating magnetic field for stimulating the affected part generated by the high-frequency output coil 15 with the high-frequency signal for biological stimulation obtained by frequency-modulating the basic high-frequency signal with the low-frequency signal for biological stimulation can further reduce the nerve damage in the affected part.

[0039] And according to the magnetic therapy device of this embodiment, the frequency of the low-frequency signal for biological stimulation is 1 kHz or more and 3 kHz or less. The stimulation by the low-frequency alternating magnetic field of 1 kHz or more and 3 kHz or less generated by the low-frequency output coil 17 with the low-frequency signal for biological stimulation is particularly likely to be conducted from the spinal cord posterior horn to the brain through the sensory nerves. Therefore, it is expected to bring about higher effects such as analgesic effects and relaxation effects through the nervous system.

[0040] As described above, the description is based on the illustrated embodiment. However, the magnetic therapy device of the present invention is not limited to the above-described embodiment and can be appropriately changed within the scope described in the claims. For example, the basic high-frequency signal shift unit may shift the basic high-frequency signal of 250 MHz within a range of, for example, 250 MHz ± 20%.

[0041] Also, for example, the low-frequency signal generation unit for biological stimulation may generate a low-frequency signal for biological stimulation in a frequency range different from 1 kHz or more and 3 kHz or less, for example, a frequency range of 200 Hz or more and 3 kHz or less with a center frequency of 1.6 kHz.

Industrial Applicability

[0042] In the magnetic therapy device of the present invention, a signal wave output unit housed in the device main body generates high-frequency and low-frequency signal waves for biological stimulation. By applying a probe separated from the device main body along the affected part of the living body, a high-frequency alternating magnetic field generated by a high-frequency output coil and a low-frequency output coil is irradiated to the affected part to stimulate the cells of the affected part. It is expected to reduce the nerve disorder of the affected part by activating the self-repair function of damaged nerves and cells in the affected part, for example, by this stimulation.

[0043] Moreover, according to the magnetic therapy device of this invention, since a slit having a plurality of crosslinks is provided on a wiring board such as a coil housed in the probe, the wiring board easily follows the deformation of the probe. Therefore, not only is the magnetic therapy effect enhanced, but also an effect of high productivity of the probe can be obtained.
