[0001] The present invention relates to a device for treating pain in an affected area of a living body by generating a signal wave for biological stimulation, irradiating a magnetic field generated in a coil by the signal wave to the affected area of the living body, and stimulating cells and nerves in the affected area.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the device described in Patent Document 1, the high-frequency coil and the low-frequency coil are housed together with the oscillating circuit and battery within the housing. Therefore, in order to irradiate the affected area with the magnetic field generated by these coils, the housing must be placed against the affected area. This has the disadvantage of the housing being bulky and getting in the way, or getting caught on clothing and falling off the affected area.

[0006] Furthermore, it was discovered that reducing the size of the casing to solve this problem would necessitate smaller oscillator circuits and batteries, leading to a new problem: insufficient magnetic field strength and operating time could not be achieved.

[0007] The probe of a magnetic therapy device needs to be able to conform to and move along the affected area of ​​the human body, such as the arm or leg, and it must be able to be easily fixed to the affected area with surgical tape or similar material, as well as be easily removable.

[0008] This invention has been made in view of these circumstances, and aims to provide a magnetic therapy device that has a high magnetic therapy effect, can be appropriately positioned to the affected area, and is easy to remove. [Means for solving the problem]

[0009] The magnetic therapy device according to the present invention, which advantageously solves the above problems, is a magnetic therapy device that generates a biostimulation signal wave and irradiates the affected area of ​​a living body with a magnetic field for stimulating the affected area generated by the biostimulation signal wave in a coil to stimulate cells and nerves in the affected area and surrounding area to treat pain in the affected area, comprising: a device body having a signal wave output unit that generates and outputs a biostimulation signal wave of a first frequency; and a probe formed separately from the device body, which is connected to the signal wave output unit by a signal cable and has a coil to which the biostimulation signal wave output from the signal wave output unit is supplied, wherein the probe is a substantially quadrilateral flat plate molded from a deformable resin and has irregularities on its upper surface to reduce the contact area of ​​adhesive tape. [Effects of the Invention]

[0010] In the magnetic therapy device of this invention, a signal wave output unit of the device body generates and outputs a biostimulation signal wave (first frequency), and a coil of a probe formed separately from the device body is connected to the signal wave output unit by a signal cable and is supplied with the biostimulation signal wave output from the signal wave generation unit, and generates an alternating magnetic field for stimulating the affected area with the biostimulation signal wave.

[0011] Therefore, according to the magnetic therapy device of this invention, by applying a probe separate from the main body of the device to the affected area of ​​the body, an alternating magnetic field for stimulating the affected area, such as a high-frequency field, generated by a single coil is irradiated onto the affected area, stimulating the cells and nerves of the affected area. This stimulation is expected to activate damaged nerves in the affected area, for example, and reduce nerve damage in the affected area through self-repair.

[0012] Furthermore, according to the magnetic therapy device of this invention, the probe is a substantially quadrilateral flat plate molded from a deformable resin and has irregularities on its upper surface that reduce the contact area of ​​the adhesive tape. Therefore, the probe can be deformed to conform appropriately to the affected area, and after being fixed to the affected area with surgical tape or the like, the surgical tape is easily peelable, making it easy to remove the probe.

[0013] Furthermore, in the magnetic therapy device of this invention, it is preferable that the probe has a textured surface or an engraved surface on its upper surface, as this allows for appropriate control of the unevenness of the probe's upper surface and is also preferable in terms of productivity.

[0014] Furthermore, in the magnetic therapy device of this invention, the signal wave output unit may also generate and output a biostimulation signal wave of a different frequency (second frequency), and the probe may also have another coil connected to the signal wave output unit by a signal cable and supplied with the biostimulation signal wave of the different frequency output from the signal wave output unit. In this way, the stimulation applied to the affected area by irradiating it with, for example, a low-frequency alternating magnetic field for stimulating the affected area, generated by the other coil using the biostimulation signal wave of the different frequency, travels through sensory nerves (Aβ fibers: touch) to the spinal cord dorsal horn and then to the brain (sensory cortex), so the brain recognizes the pleasantness of touch, and it can be expected that the descending pain inhibitory system will be activated, resulting in analgesic and relaxing effects. [Brief explanation of the drawing]

[0015] [Figure 1] This is an overall conceptual diagram of a magnetic therapy device according to one embodiment of the present invention. [Figure 2] This is a schematic diagram showing the probe of the magnetic therapy device according to the above embodiment, where (a) represents a top view, (b) represents a rear view, and (c) represents a cross-sectional view AA. [Figure 3] The above embodiment of the magnetic therapy device is shown in the printed wiring diagram, where (a) represents a top view and (b) represents a bottom view. [Figure 4] In the magnetic therapy device according to the above embodiment, (a) is a schematic perspective view of the probe fixed to the upper arm with surgical tape, and (b) is a cross-sectional view of BB. [Modes for carrying out the invention]

[0016] The embodiments of the present invention will be described in detail below. Note that the drawings are schematic and may differ from actual examples. Furthermore, the following embodiments are illustrative examples of methods for realizing the technical concept of the present invention and do not limit the configuration to those described below. In other words, the technical concept of the present invention can be modified in various ways within the technical scope described in the claims.

[0017] Figure 1 shows an overall conceptual diagram of a magnetic therapy device according to one embodiment of the present invention. In the following figures, reference numeral 1 denotes the main body of the magnetic therapy device of this embodiment, reference numeral 11 denotes a probe, and reference numeral 21 denotes a signal cable. The device also includes a power cable (not shown) that is detachably plugged into the main body 1.

[0018] The main body 1 of the magnetic therapy device in this embodiment includes a resin casing 2, a touch panel display 3 housed diagonally upward in the front part of the casing 2 and exposed through an opening on the front of the casing 2, a signal wave output unit housed in the upper rear part of the casing 2, and a power supply unit housed in the lower rear part of the casing 2. An alarm stop button and a power switch button are provided on the left and right sides of the lower part of the opening on the front of the casing 2 of the main body 1. Further below these buttons, three sockets for plugging signal cables 21 are provided side by side to allow connection of three probes 11 to the main body 1.

[0019] Figure 2 shows a top view (a), a rear view (b), and a cross-sectional view (c) of the probe 11 of the magnetic therapy device in this embodiment. In this embodiment, the probe 11 has a roughly quadrilateral flexible outer casing 12 and a truncated pyramidal raised portion 13 for routing the signal cable 21, for the purpose of protecting electrical circuits and the like.

[0020] As shown in FIG. 2(c) and FIG. 3, the probe 11 houses a flexible thin plate 14, which is a printed circuit board with coils and electric circuits, within a resin exterior 12 made of an elastomer, rubber material, or the like. The probe 11 can be manufactured by resin molding such as injection molding or RIM molding. A mold for protecting the electronic circuit portion 13a can be pre-raised, for example, with a heat-resistant silicone-based resin. When resin-molding the probe 11, by using the mold that protects the electronic circuit portion 13a as a raised portion 13 for leading out the signal cable 21, the flat exterior 12 can be easily deformed, and the electronic circuit portion 13a is protected from deformation by the thick and rigid raised portion 13. Therefore, it is possible to achieve both easy deformation of the probe and an improvement in its lifespan.

[0021] FIG. 3 is a printed wiring diagram showing the coil arrangement of the magnetic therapy device of this embodiment, representing a top view (a) and a bottom view (b). On the printed circuit board 14, an electronic circuit portion 13a, a high-frequency output coil 15 as one coil for outputting a first frequency, a magnetic field strength detection coil 16, a low-frequency output coil 17 as another coil for outputting 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 ring outside it. 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 to be symmetric with respect to the plane 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 connected by bridge portions 19, enabling stable molding when covering the printed circuit board 14 with resin molding. Note that the high-frequency output coil 15, the magnetic field strength detection coil 16, and the low-frequency output coil may be changed to a rectangular shape instead of an annular shape.

[0022] Fig. 4(a) shows a schematic perspective view of the state where the probe 11 is fixed along the upper arm part M with the surgical tape S. Fig. 4(b) shows a sectional view taken along line B-B of the contact state between the surgical tape S and the upper surface of the exterior 12 of the probe 11. The probe 11 is preferably a substantially quadrilateral, particularly a substantially rectangular flat plate, which is easy to attach to the limbs of a person with the affected part and is easy to fix with a tape. When the sides W and L of the quadrilateral of the probe 11 are in the range of 25 to 75 mm, for example, it is possible to run along about half of 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 life considering the wear of the probe. The upper limit of the thickness is preferably determined from the fact that it can be appropriately deformed manually.

[0023] Also, as shown in Fig. 4(b), the upper surface of the planar part of the probe 11 has concavo-convex parts 12a, which reduces the contact surface with the surgical tape S. With this configuration, it is possible to reduce the adhesive force of the surgical tape S and improve the peelability from the probe 11. As a processing method for forming the concavo-convex parts 12a, it is preferable to perform molding by a mold typified by embossing in which concavo-convex are provided on the mold and transferred, or engraving processing for shaving the resin surface. In embossing, the surface of the mold can be sandblasted or made into a satin finish by chemical etching. Also, striped grooves or twill-like grooves can be transferred. In engraving processing, it is possible to mechanically shave or perform thermal processing with a laser beam. The contact area ratio between the adhesive part of the surgical tape S and the planar part of the exterior 12 of the probe 11 is preferably about 30 to 80%. If it is less than the lower limit, the adhesive force is too low and there is a risk of peeling off during magnetic therapy. If it exceeds the upper limit, the effect of reducing the adhesive force is not sufficient. The contact area ratio can be adjusted by increasing or decreasing the depth of the recess of the concavo-convex processing and changing the concavo-convex shape. <00001"00> In this embodiment of the magnetic therapy device, the main unit 1 functionally comprises 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 multiple central processing units (CPUs). A basic high-frequency signal generation unit generates a basic high-frequency signal of 100 MHz or higher. The basic high-frequency signal shifting unit shifts (varies) this basic high-frequency signal appropriately at regular intervals, for example, 0.00014 seconds (i.e., approximately 7000 times / second), within a range of 225 MHz to 275 MHz, which is ±10% of 250 MHz, while excluding the frequency band used by aircraft life-saving radios. The shifted basic high-frequency signal is then output to the basic high-frequency signal frequency modulation unit. While there is no particular upper limit to the frequency, around 400 MHz is preferable from the standpoint of the effectiveness of magnetic therapy.

[0025] The signal wave output unit also reads magnetic signal patterns, including sound source signals such as music, that have been pre-recorded on an external storage device such as an SD card inserted in a card slot or on an internal storage device, from the SD card or other device using the magnetic signal pattern reading unit and supplies them to the biostimulation low-frequency signal generation unit. The biostimulation low-frequency signal generation unit generates a biostimulation low-frequency signal from the frequency information (for example, 1 kHz or higher and 3 kHz or lower) of the magnetic signal pattern and outputs the biostimulation low-frequency signal to the basic high-frequency signal frequency modulation unit.

[0026] The basic high-frequency signal frequency modulation unit then frequency modulates a basic high-frequency signal, for example 250 MHz ± 10%, generated by the basic high-frequency signal generation unit and frequency-shifted by the basic high-frequency signal shift unit, with a biostimulation low-frequency signal, for example, between 1 kHz and 3 kHz, generated by the biostimulation low-frequency signal generation unit, and supplies it to the biostimulation high-frequency signal output unit. The biostimulation high-frequency signal output unit then amplifies and outputs the frequency-modulated biostimulation high-frequency signal. Alternatively, the biostimulation high-frequency signal output unit may amplitude modulate the frequency-modulated biostimulation high-frequency signal with the biostimulation low-frequency signal before amplifying and outputting it. Furthermore, the biostimulation low-frequency signal output unit may amplify and output a biostimulation low-frequency signal, for example, between 1 kHz and 3 kHz, generated by the biostimulation low-frequency signal generation unit. These operations in the signal wave output unit are controlled by the operation state control unit.

[0027] In this embodiment, the probe 11 houses a flexible printed circuit board, on which a high-frequency output coil 15 is formed by printed wiring 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. Furthermore, an operating state detection unit is circuit-configured using a temperature detection element and a CPU mounted on the flexible printed circuit board. The high-frequency output coil 15 generates a high-frequency alternating magnetic field for stimulating the affected area with a high-frequency signal for biostimulation supplied via a signal cable 21 from a high-frequency signal output unit for biostimulation. The low-frequency output coil 17 may generate a low-frequency alternating magnetic field for stimulating the affected area with a low-frequency signal for biostimulation supplied via a signal cable 21 from a low-frequency signal output unit for biostimulation.

[0028] The operating state detection unit detects the operating state of the signal wave output unit from the temperatures of the high-frequency output coil 15 and low-frequency output coil 17 detected by the temperature detection element and the high-frequency or low-frequency magnetic field strength detected by the magnetic field strength detection coil 16, and inputs a signal indicating the operating state to the signal wave output unit's operating state monitoring unit via the signal cable 21. Based on this signal indicating the operating state, the operating state monitoring unit monitors the operation of the signal wave output unit, such as signal wave generation and output, and consequently the level of the alternating magnetic field generated by the high-frequency output coil 15 and low-frequency output coil 17. If an abnormality is detected, the alarm control unit outputs an alarm signal (for example, an alarm sound is emitted from a speaker (not shown) built into the main unit 1, or an alarm message is displayed on the display 3). The sound of this alarm can be stopped by operating the alarm stop button on the front of the casing of the main unit 1. Furthermore, upon detecting an abnormality, the operation state control unit immediately stops the supply of high-frequency signals for biostimulation from the high-frequency signal output unit to the high-frequency output coil 15 and the supply of low-frequency signals for biostimulation from the low-frequency signal output unit to the low-frequency output coil 17, in order to ensure the safety of the user of the magnetic therapy device.

[0029] In this embodiment, the screen control unit is configured using a graphics processing unit (GPU) or the like. The image display unit reads screen information, such as instruction buttons, to be displayed on the liquid crystal display (LCD) of the touch input display 3, which is pre-recorded on an external storage device such as an SD card inserted in a card slot, and displays it on the LCD. Furthermore, the instruction input unit detects the position where the user's finger touches the touch panel of the touch input display 3 based on changes in static electricity at that position, and sends a signal indicating instruction input by an operation button displayed on the LCD, corresponding to that touch position, to the operation state control unit. Based on this instruction input signal, the operation state control unit controls the operation of the signal wave output unit, such as signal wave generation and output, and consequently the alternating magnetic field generated by the high-frequency output coil 15 and the low-frequency output coil 17, according to the user's instructions.

[0030] The screen control unit also creates a log that records the instruction input to the instruction input unit via the operation buttons displayed on the LCD or the like, and the operating status of the signal wave output unit at that time. This log information is saved in a USB memory (not shown) that is removably inserted into a USB memory slot in the protrusion on the lower rear side of the casing 2 from the top side of the protrusion. Furthermore, the image display unit has a clock function that displays the time on the LCD or the like, and this clock function is maintained by a button battery installed in the battery holder.

[0031] In this embodiment, the power supply unit is circuit-configured with a CPU (not shown) and two AC-DC converters. A 100V commercial AC power supply is supplied via a power cable (not shown), and a predetermined DC power supply is obtained by the two AC-DC converters. These DC power supplies are connected in series to obtain the battery charging voltage and charge the battery. At the same time, a predetermined DC power supply, obtained by stepping down the voltage from these DC power supplies using a switching power supply and a linear regulator, is supplied as a DC power supply of the required voltage to the signal wave output unit and screen control unit of the device body 1 and the operating state detection unit of the probe 11, respectively.

[0032] Furthermore, when the magnetic therapy device is in normal use without a power cable attached, the power supply unit supplies DC power from the battery to the signal wave output unit and screen control unit of the device body 1 and the operating state detection unit of the probe 11, stepping down the voltage to the required DC voltage using a switching power supply and a linear regulator, thereby enabling the magnetic therapy device to be used as a portable device.

[0033] In this embodiment of the magnetic therapy device, the basic high-frequency signal generation unit, basic high-frequency signal shifting unit, and basic high-frequency signal frequency modulation unit of the signal wave output unit of the device body 1 generate a high-frequency signal for biostimulation, which is output by the biostimulation high-frequency signal output unit. A high-frequency output coil 15 of the probe 11, which is formed separately from the device body 1, is connected to the biostimulation high-frequency signal output unit of the signal wave output unit by a signal cable 21, and is supplied with a biostimulation high-frequency signal, for example, with a center frequency of 250 MHz, which is output from the biostimulation high-frequency signal output unit, and generates a high-frequency alternating magnetic field for stimulating the affected area with this biostimulation high-frequency signal.

[0034] Therefore, according to the magnetic therapy device of this embodiment, by applying the probe 11, which is separate from the main body 1 of the device, to the affected area of ​​the body, the high-frequency alternating magnetic field generated by the high-frequency output coil 15 is irradiated onto the affected area to stimulate the cells and nerves of the affected area. This stimulation is expected to activate damaged nerves in the affected area, for example, and reduce nerve damage through self-repair. The central 250MHz high-frequency alternating magnetic field is expected to enhance the effect of activating damaged nerves and reducing nerve damage through self-repair.

[0035] Furthermore, according to the magnetic therapy device of this embodiment, the biostimulation low-frequency signal generation unit of the signal wave output unit of the device body 1 generates a biostimulation low-frequency signal from the frequency information of the magnetic signal pattern (for example, 1 kHz or higher and 3 kHz or lower), the biostimulation low-frequency signal output unit outputs the biostimulation low-frequency signal, and the low-frequency output coil 17 of the probe 11 is connected to the biostimulation low-frequency signal output unit of the signal wave output unit by a signal cable 21 and supplied with a biostimulation low-frequency signal from the biostimulation low-frequency signal output unit. As a result, the low-frequency alternating magnetic field for stimulating the affected area generated by the low-frequency output coil 17 by the biostimulation low-frequency signal is irradiated onto the affected area, and the stimulation transmitted is carried by sensory nerves (Aβ fibers: touch) from the spinal cord dorsal horn to the brain (sensory cortex). Therefore, it can be expected that the brain recognizes the pleasantness of touch, activates the descending pain inhibitory system, and brings about analgesic and relaxing effects.

[0036] 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 body 1 frequency modulates the basic high-frequency signal with the low-frequency signal for biostimulation generated by the signal wave output unit to generate a high-frequency signal for biostimulation, and the high-frequency signal output unit for biostimulation supplies the frequency-modulated high-frequency signal for biostimulation to the high-frequency output coil 15 of the probe 11. As a result, the cells and nerves in the affected area are stimulated by the high-frequency alternating magnetic field for stimulating the affected area generated by the high-frequency output coil 15 using the high-frequency signal for biostimulation that has been frequency-modulated with the low-frequency signal for biostimulation. This is expected to activate the damaged nerves in the affected area more than in the absence of frequency modulation, thereby reducing nerve damage in the affected area through self-repair.

[0037] Furthermore, according to the magnetic therapy device of this embodiment, the signal wave output unit of the device body 1 also generates and outputs a low-frequency signal for biostimulation, the probe 11 is connected to the signal wave output unit by a signal cable 21, and also has a low-frequency output coil 17 to which the low-frequency signal for biostimulation is supplied from the signal wave output unit, and the signal wave output unit generates a high-frequency signal for biostimulation by frequency modulating the basic high-frequency signal with the low-frequency signal for biostimulation and outputs it separately from the low-frequency signal for biostimulation. As a result, it is expected that the low-frequency alternating magnetic field for stimulating the affected area generated by the low-frequency output coil 17 by the low-frequency signal for biostimulation will provide analgesic and relaxing effects, and that the high-frequency alternating magnetic field for stimulating the affected area generated by the high-frequency output coil 15 by the high-frequency signal for biostimulation, which is obtained by frequency modulating the basic high-frequency signal with the low-frequency signal for biostimulation, will further reduce nerve damage in the affected area.

[0038] Furthermore, according to the magnetic therapy device of this embodiment, the frequency of the biostimulation low-frequency signal is 1 kHz or higher and 3 kHz or lower. The stimulation from the low-frequency alternating magnetic field of 1 kHz or higher and 3 kHz or lower generated by the low-frequency output coil 17 by this biostimulation low-frequency signal is particularly likely to reach the brain from the spinal cord dorsal horn via sensory nerves, thus it is expected to produce more analgesic and relaxing effects, and other effects mediated through the nervous system.

[0039] Although the above description is based on the illustrated embodiments, the magnetic therapy apparatus of this invention is not limited to the embodiments described above and can be modified as appropriate within the scope of the claims. For example, the basic high-frequency signal shifting unit may shift a 250 MHz basic high-frequency signal within a range of, for example, 250 MHz ± 20%.

[0040] Furthermore, for example, the biostimulation low-frequency signal generation unit may generate biostimulation low-frequency signals in a frequency range different from 1 kHz or higher and 3 kHz or lower, for example, a frequency range of 200 Hz or higher and 3 kHz or lower with a center frequency of 1.6 kHz. [Industrial applicability]

[0041] The magnetic therapy device of the present invention generates high-frequency and low-frequency biostimulatory signal waves in a signal wave generation unit housed in the main body of the device. By applying a probe, separate from the main body of the device, to the affected area of ​​the body, the high-frequency alternating magnetic field generated by the high-frequency coil and the low-frequency coil is irradiated onto the affected area, stimulating the cells and nerves in the affected area. This stimulation is expected to alleviate nerve damage in the affected area by activating the self-repair function of damaged nerves and cells, for example.

[0042] Furthermore, according to the magnetic therapy device of this invention, the probe is made of a roughly quadrilateral flat plate molded from a deformable resin, and a raised portion for signal cable extraction is provided on the upper surface of the electronic circuit section for protection, thereby achieving both ease of deformation of the probe and improved lifespan.
