Description

[Technical Field]

[0001] The present invention relates to a device that generates a signal wave for biostimulation, generates a magnetic field in a coil using the signal wave, and irradiates the affected area of ​​the living body with the magnetic field to stimulate the cells and nerves in the affected area, thereby treating pain in the affected area. [Background technology]

[0002] Conventionally, a device for treating pain in an affected area by irradiating a magnetic field onto the affected area of ​​a living body to stimulate the cells and nerves in the affected area is known, for example, as described in Patent Document 1.This treatment device is configured to be portable by arranging a spiral-shaped high-frequency coil and a low-frequency coil side by side within a housing, or by arranging a loop-shaped high-frequency coil and a low-frequency coil stacked on top of each other within a housing, and storing these coils together with a transmitting circuit and a battery within the housing.

[0003] This treatment device generates magnetic fields in the high-frequency coil and low-frequency coil using high-frequency and low-frequency signals of constant frequency output from the transmitting circuit, and by placing the casing over the affected area of ​​the body, the magnetic field is irradiated onto the affected area, stimulating the cells and nerves in the area.This stimulation activates the self-repair function of the affected area, repairing the cells and tissues and thereby treating the pain in the affected area. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2008 / 056414 Summary of the Invention [Problem 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 in a housing together with the transmitting circuit and battery, so in order to irradiate the magnetic field generated by these coils to the affected area, the housing must be placed on the affected area, which has the inconvenience of making the housing bulky and getting in the way, or getting caught on clothing and falling off the affected area.

[0006] It was discovered that if the housing were made smaller to solve this problem, the transmitting circuit and battery would also need to be made smaller, which would create a new problem in that sufficient magnetic field strength and operating time could not be obtained.

[0007] The probe of a magnetic therapy device must be able to contact and deform to fit the affected area of ​​the human body, such as an arm or leg, and must be designed to ensure high yield during the manufacturing process.

[0008] The present invention has been made in view of the above circumstances, and has an object to provide a magnetic therapeutic device that has a high magnetic therapeutic effect and can be fitted appropriately to the affected area. [Means for solving the problem]

[0009] The magnetic therapy device of the present invention, which advantageously solves the above-mentioned problems, is a magnetic therapy device that generates biostimulation signal waves, generates a magnetic field for stimulating the affected area in a coil using the biostimulation signal waves, and irradiates the affected area of ​​a living body with a magnetic field for stimulating the affected area, thereby stimulating the cells and nerves in and around the affected area, thereby treating pain in the affected area.The magnetic therapy device comprises a device main body having a signal wave output unit that generates and outputs biostimulation signal waves of a first frequency, and a probe formed separately from the device main body, which is connected to the signal wave output unit by a signal cable and has a coil to which the biostimulation signal waves output from the signal wave output unit are supplied, and the probe is a roughly quadrilateral flat plate molded from a deformable resin, and has a raised portion on its upper surface for pulling out the signal cable. [Effects of the Invention]

[0010] In the magnetic therapy device of this invention, a signal wave output unit possessed by the device main body generates and outputs a biostimulation signal wave (first frequency), and one coil possessed by a probe formed separately from the device main 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 generating unit, and the biostimulation signal wave generates an alternating magnetic field for stimulating the affected area.

[0011] Therefore, with the magnetic therapy device of this invention, by applying a probe separate from the device body to the affected area of ​​a living body, a high-frequency alternating magnetic field for stimulating the affected area, generated by one coil, for example, is irradiated onto the affected area, stimulating the cells and nerves in and around the affected area, and 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 roughly quadrilateral flat plate molded from deformable resin, and has a raised portion on the top surface for pulling out the signal cable, so the probe can be deformed to fit appropriately to the affected area, and the cable for sending and receiving signals can be securely connected to the probe, making the probe more durable.

[0013] In addition, the magnetic therapy device of this invention contains an insulating flexible thin plate having a coil section in which coils including the one coil are wired, and an electronic circuit section including a central processing unit, and it is preferable to have a protective means for covering the electronic circuit section, as this can protect the electronic circuit section during the resin molding stage of the probe and improve manufacturing yield.

[0014] In the magnetic therapy device of the present invention, it is preferable to have an electronic circuit section within the raised portion for pulling out the cable, since this allows for efficient manufacturing of the probe.

[0015] In addition, in the magnetic therapy device of the present 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 given by irradiating the affected area with a low-frequency alternating magnetic field for stimulating the affected area, which is generated in the other coil by the biostimulation signal wave of the different frequency, travels through sensory nerves (Aβ fibers: touch) and reaches the brain (sensory area) from the dorsal horn of the spinal cord, so that the brain recognizes the pleasantness of the touch and activates the descending pain inhibitory system, which is expected to bring about an analgesic effect or a relaxing effect.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the present invention will be described in detail. Note that the drawings are schematic and may differ from the actual product. Furthermore, the following embodiments are intended to exemplify methods for embodying the technical concept of the present invention, and are not intended to limit the configuration to the following. In other words, the technical concept of the present invention can be modified in various ways within the technical scope described in the claims.

[0018] An overall conceptual diagram of a magnetic therapy device according to one embodiment of the present invention is shown in Figure 1. In the following figures, reference numeral 1 denotes the device main body provided with 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 inserted into the device main body 1.

[0019] The device main body 1 of the magnetic therapy device of this embodiment has a resin casing 2, a touch panel display 3 housed diagonally upward in the front part of the casing 2 and exposed from an opening in the front of the casing 2, a signal wave output unit housed in the upper part of the rear of the casing 2, and a power supply unit housed in the lower part of the rear of the casing 2. An alarm stop button and a power switch button are provided on the left and right sides below the opening in the front of the casing 2 of the device main body 1. Further below these buttons, three sockets for plugging in signal cables 21 are provided side by side to enable connection of three probes 11 to the device main body 1.

[0020] 2A shows a top view, a back view, and an AA cross-sectional view of the probe 11 of the magnetic therapy device of this embodiment. In this embodiment, the probe 11 has a roughly quadrilateral exterior 12 made of a flexible material and a truncated pyramidal portion 13 for pulling out the signal cable 21 in order to protect the electrical circuitry.

[0021] As shown in FIG. 2(c), the probe 11 contains a flexible thin plate 14, which is a printed circuit board on which a coil and an electric circuit are arranged, in an exterior 12 made of a resin such as an elastomer or rubber material.

[0022] FIG. 3 is a printed wiring diagram showing the coil arrangement of the magnetic therapy device of this embodiment, showing a top view (a) and a bottom view (b). An electronic circuit unit 13a, a high-frequency output coil 15 as one coil that outputs a first frequency, a magnetic field strength detection coil 16, and a low-frequency output coil 17 as another coil that outputs a second frequency are arranged on a printed circuit board 14. In this embodiment, the high-frequency output coil 15 is an annular disk on the upper surface of the printed circuit board 14, and the magnetic field strength detection coil 16 is an annular disk arranged on the outer side. A spiral-shaped 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 each other so that high-frequency current and low-frequency current flow in the same direction on both the upper and lower surfaces. This allows the centers of the magnetic fields generated by the coils on both the upper and lower surfaces to coincide. A slit 18 is provided between the high-frequency output coil 15 and the low-frequency output coil of the printed circuit board 14, making it easier for the printed circuit board 14 to follow the deformation of the probe 11. In addition, multiple points on the circumference of the slit 18 are connected by bridge portions 19, allowing for stable molding when the printed circuit board 14 is covered with resin. Note that the high-frequency output coil 15, magnetic field strength detection coil 16, and low-frequency output coil may be rectangular instead of annular.

[0023] The probe 11 is preferably a generally quadrilateral, particularly a generally rectangular flat plate, which makes it easy to attach to the affected limb of a person and fix with tape. The size of the probe 11 is such that the sides W and L of the quadrilateral are in the range of 25 to 75 mm, allowing it to fit around half the circumference of an arm, for example, and thus improving the therapeutic effect. The thickness t is preferably in the range of 0.2 to 5 mm. The lower limit of the thickness is preferably determined based on the insulating properties of the wiring on the printed circuit board and the lifespan of the probe, taking into account wear and tear. The upper limit of the thickness is preferably determined based on the ability to deform the probe appropriately by hand.

[0024] The probe 11 can be manufactured by resin molding such as injection molding or RIM molding. FIG. 4 is a perspective view showing how the electronic circuit section 13a is protected. The mold 13b that protects the electronic circuit section 13a can be made of, for example, a heat-resistant silicone resin. When resin molding the probe 11, the coil section is placed on the flat surface of the exterior 12, and the mold 13b that protects the electronic circuit section 13a is made into the raised section 13 for pulling out the signal cable 21. This makes it easy to deform the flat exterior 12, and the electronic circuit section 13a is protected from deformation by the thick, rigid raised section 13. This therefore achieves both ease of deformation of the probe and an extended lifespan.

[0025] In this embodiment of the magnetic therapy device, the device main body 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 configured using multiple central processing units (CPUs), and the fundamental high-frequency signal generating unit generates a fundamental high-frequency signal of 100 MHz or more. The fundamental high-frequency signal shifting unit appropriately shifts (varies) the fundamental high-frequency signal, for example, at a center frequency of 250 MHz within a range of 225 MHz to 275 MHz, which is ±10% of the center frequency, excluding the frequency band used in aircraft emergency locators, for example, every 0.00014 seconds (i.e., approximately 7000 times per second), and outputs the shifted fundamental high-frequency signal to the fundamental high-frequency signal frequency modulation unit. The upper limit of the frequency is not particularly limited, but a frequency of around 400 MHz is preferable in terms of the effectiveness of magnetic therapy.

[0026] The signal wave output unit also reads 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 inserted in a card slot or in an internal storage device, from the SD card or the like using a magnetic signal pattern reading unit, and supplies the read magnetic signal pattern to a biostimulation low-frequency signal generation unit, which generates a biostimulation low-frequency signal from the frequency information of the magnetic signal pattern (for example, 1 kHz or more and 3 kHz or less), and outputs the biostimulation low-frequency signal to a fundamental high-frequency signal frequency modulation unit.

[0027] The fundamental high-frequency signal frequency modulation unit frequency-modulates the fundamental high-frequency signal, for example, 250 MHz ± 10%, generated by the fundamental high-frequency signal generation unit and frequency-shifted by the fundamental high-frequency signal shift unit, with the biostimulation low-frequency signal, for example, 1 kHz or more and 3 kHz or less, generated by the biostimulation low-frequency signal generation unit, and supplies the frequency-modulated biostimulation high-frequency signal output unit, which amplifies and outputs the frequency-modulated biostimulation high-frequency signal. Note that the biostimulation high-frequency signal output unit may amplitude-modulate the frequency-modulated biostimulation high-frequency signal with the biostimulation low-frequency signal, and then amplify and output the signal. The biostimulation low-frequency signal output unit may also amplify and output the biostimulation low-frequency signal, for example, 1 kHz or more and 3 kHz or less, generated by the biostimulation low-frequency signal generation unit. These operations of the signal wave output unit are controlled by the operating state control unit.

[0028] In this embodiment, probe 11 houses a flexible printed wiring board, on which a high-frequency output coil 15 is formed on the outside and a low-frequency output coil 17 is formed on the inside using printed wiring. In addition, a magnetic field strength detection coil 16 is formed on the outside of high-frequency output coil 15. Furthermore, an operating state detection unit is configured as a circuit using a temperature detection element and a CPU mounted on the flexible printed wiring board. High-frequency output coil 15 generates a high-frequency alternating magnetic field for stimulating the affected area using a high-frequency signal for biostimulation supplied from a high-frequency signal output unit for biostimulation via a signal cable 21. Low-frequency output coil 17 may generate a low-frequency alternating magnetic field for stimulating the affected area using a low-frequency signal for biostimulation supplied from a low-frequency signal output unit for biostimulation via a signal cable 21.

[0029] 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 the 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 this operating state to the operating state monitoring unit of the signal wave output unit via signal cable 21. Using this operating state signal, the operating state monitoring unit monitors the operation of the signal wave output unit, such as signal wave generation and output, and the level of the alternating magnetic field generated by the high-frequency output coil 15 and the low-frequency output coil 17, and if it detects an abnormality, it outputs an alarm signal (for example, sounding an alarm from a speaker (not shown) built into the device main body 1, displaying an alarm message on the display 3, etc.) via the alarm control unit. The sounding of this alarm can be stopped by operating the alarm stop button on the front of the casing of the device main body 1. In addition, upon detecting an abnormality, the operating 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 to ensure the safety of the user of the magnetic therapy device.

[0030] In this embodiment, the screen control unit is configured as a circuit using a graphics processing unit (GPU), and 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, pre-stored in an external storage device such as an SD card inserted in a card slot, from the SD card 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 from changes in static electricity at that position, and sends a signal indicating an instruction input via the operation button displayed on the LCD corresponding to the touch position to the operation state control unit. Based on this signal indicating the instruction input, the operation state control unit controls the signal wave generation and output operations of the signal wave output unit, and ultimately the alternating magnetic fields generated by the high-frequency output coil 15 and the low-frequency output coil 17, in accordance with the user's instructions.

[0031] The screen control unit also creates a log that records the instructions input to the instruction input unit using the operation buttons displayed on the LCD, etc., and the operating status of the signal wave output unit at that time, and saves the log information in a USB memory (not shown) that is attached to a USB memory slot in the protrusion on the lower rear of the casing 2 so that it can be inserted and removed from the top side of the protrusion.Furthermore, the image display unit has a clock function that displays a clock on the LCD, etc., and this clock function is maintained by a button battery attached to the battery holder.

[0032] The power supply unit in this embodiment is a 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 the two AC-DC converters generate a predetermined DC power supply. These DC power supplies are connected in series to obtain a battery charging voltage, which is then used to charge the battery. The predetermined DC power supply is stepped down from these DC power supplies by a switching power supply and a linear regulator, and the resulting DC power supply is supplied to the signal wave output unit and screen control unit of the device main body 1 and the operating state detection unit of the probe 11 as DC power supplies of the required voltages.

[0033] During normal use of the magnetic therapy device 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 main body 1 and the operating status detection unit of the probe 11, after reducing the voltage to the required DC voltage using a switching power supply and linear regulator, making the magnetic therapy device portable and usable.

[0034] In this embodiment of the magnetic therapy device, the fundamental high-frequency signal generating section, fundamental high-frequency signal shifting section, and fundamental high-frequency signal frequency modulating section of the signal wave output section of the device main body 1 generate a high-frequency signal for biostimulation, which is output by the high-frequency signal output section for biostimulation, and the high-frequency output coil 15 of the probe 11 formed separately from the device main body 1 is connected by a signal cable 21 to the high-frequency signal output section for biostimulation of the signal wave output section, and is supplied with a high-frequency signal for biostimulation having a center frequency of, for example, 250 MHz, which is output from the high-frequency signal output section for biostimulation, and this high-frequency signal for biostimulation generates a high-frequency alternating magnetic field for stimulating the affected area.

[0035] Therefore, according to the magnetic therapy device of this embodiment, by applying a probe 11 separate from the device main body 1 to the affected area of ​​a living 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 in the affected area, and this stimulation is expected to activate, for example, damaged sensory cells in the affected area and induce neurotrophic factors, thereby alleviating nerve damage in the affected area.The central high-frequency alternating magnetic field of 250 MHz has a high effect of activating damaged sensory cells and inducing neurotrophic factors, and is therefore expected to enhance the effect of alleviating nerve damage in the affected area.

[0036] Furthermore, according to the magnetic therapy device of this embodiment, the biostimulation low-frequency signal generating section of the signal wave output section of the device main body 1 generates a biostimulation low-frequency signal from the frequency information of the magnetic signal pattern (for example, 1 kHz or more and 3 kHz or less), and the biostimulation low-frequency signal output section 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 section of the signal wave output section by a signal cable 21, and the biostimulation low-frequency signal is supplied from the biostimulation low-frequency signal output section.The low-frequency alternating magnetic field for stimulating the affected area, generated by the biostimulation low-frequency signal in the low-frequency output coil 17, is irradiated onto the affected area, and the stimulation given by this biostimulation low-frequency signal travels along the sensory nerves (Aβ fibers: touch) and reaches the brain (sensory area) from the posterior horn of the spinal cord, so that the brain recognizes the pleasantness of the touch, activating the descending pain inhibitory system and bringing about an analgesic effect and a relaxing effect.

[0037] Furthermore, according to the magnetic therapy device of this embodiment, the fundamental high-frequency signal modulation section of the signal wave output section 13 of the device main body 1 frequency-modulates the fundamental high-frequency signal with the low-frequency signal for biostimulation generated by the signal wave output section to generate a high-frequency signal for biostimulation, and the high-frequency signal output section for biostimulation supplies the frequency-modulated high-frequency signal for biostimulation to the high-frequency output coil 15 of the probe 11.Therefore, by stimulating the cells and nerves in the affected area with 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, it is expected that damaged sensory cells in the affected area will be activated more than in the case where frequency modulation is not performed, and more neurotrophic factors will be induced, thereby further alleviating nerve damage in the affected area.

[0038] Furthermore, according to the magnetic therapy device of this embodiment, the signal wave output unit of the device main body 1 also generates and outputs a low-frequency signal for biostimulation, and 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 frequency-modulates the fundamental high-frequency signal with the low-frequency signal for biostimulation to generate a high-frequency signal for biostimulation and outputs it separately from the low-frequency signal for biostimulation.Therefore, it is expected that the low-frequency alternating magnetic field for stimulating the affected area generated by the low-frequency signal for biostimulation in the low-frequency output coil 17 will have an analgesic effect and a relaxing effect, and that the high-frequency alternating magnetic field for stimulating the affected area generated by the high-frequency signal for biostimulation in the high-frequency output coil 15 will further reduce nerve damage in the affected area.

[0039] Furthermore, according to the magnetic therapy device of this embodiment, the frequency of the low-frequency signal for biostimulation is 1 kHz or more and 3 kHz or less, and the stimulation by the low-frequency alternating magnetic field of 1 kHz or more and 3 kHz or less generated in the low-frequency output coil 17 by the low-frequency signal for biostimulation is particularly likely to be conducted from the posterior horn of the spinal cord to the brain via the sensory nerves, and therefore it can be expected to bring about effects mediated by the nervous system, such as a higher analgesic effect and a relaxing effect.

[0040] The above explanation has been based on the illustrated embodiment, but the magnetic therapy device of the present invention is not limited to the above embodiment and can be modified as appropriate within the scope of the claims. For example, the fundamental high-frequency signal shift unit may shift a 250 MHz fundamental high-frequency signal within a range of 250 MHz ±20%, for example.

[0041] Furthermore, for example, the biostimulation low-frequency signal generating section may generate a biostimulation low-frequency signal in a frequency range different from 1 kHz or more and 3 kHz or less, for example, in 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 generating unit housed in the device main body generates high-frequency and low-frequency signal waves for biostimulation, and by applying a probe separate from the device main body along the affected area of ​​the living body, the high-frequency alternating magnetic field generated by the high-frequency coil and low-frequency coil is irradiated onto the affected area, stimulating the cells and nerves in the affected area.This stimulation is expected to activate the self-repair function of damaged nerves and cells in the affected area, for example, and thereby alleviate nerve damage in the affected area.

[0043] Furthermore, according to the magnetic treatment device of this invention, the probe is an approximately quadrilateral flat plate molded from deformable resin, and a raised portion for pulling out the signal cable is provided on the top surface of the electronic circuit section for protection, thereby achieving both ease of deformation of the probe and an extended lifespan.
