Description

Technical Field

[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 onto the affected area of the living body to stimulate cells in the affected area.

Background Art

[0002] Conventionally, as a device for treating pain in an affected area of a living body by irradiating a magnetic field onto the affected area to stimulate cells in the affected area, for example, the one described in Patent Document 1 is known. This treatment device is configured to be portable by accommodating a high-frequency coil and a low-frequency coil in a housing together with a transmission circuit and a battery, each in a spiral or loop shape.

[0003] Then, this treatment device generates magnetic fields in the high-frequency coil and the low-frequency coil respectively by high-frequency signals and low-frequency signals of a certain frequency output from the transmission circuit, irradiates the magnetic field onto the affected area by applying the housing to the affected area of the living body to stimulate cells in the affected area, promotes the production of a group of neurotrophic factors in the cells of the affected area by the stimulation, and promotes the repair, growth, differentiation, and proliferation of the cells to treat the pain in the affected area.

[0004] Further, Patent Document 2 discloses a system for electromagnetic induction therapy, etc., which includes one or more probes that conform to ergonomics or the body contour, and the probes include one or more conductive coils configured to generate an electromagnetic field or a magnetic field focused on a target nerve, muscle, or other body tissue positioned close to the coil. One or more sensors are used to detect the stimulation and provide feedback regarding the effectiveness of the applied electromagnetic induction therapy, and a controller is adjustable to vary the current passing through the coil and adjust the magnetic field focused on the target nerve, muscle, or other body tissue based on the feedback provided by the sensor or the patient.

[0005] [Patent Document 1] International Publication No. 2008 / 056414 [Patent Document 2] Special Publication No. 2013-508119 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] However, in the device described in Patent Document 1, the high-frequency coil, low-frequency coil, oscillator circuit, and battery are all housed together in the casing. Therefore, in order to irradiate the affected area with the magnetic field generated by these coils, the casing must be placed against the affected area. This has the disadvantage of the casing being bulky and getting in the way, or getting caught on clothing and falling off the affected area.

[0007] 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.

[0008] The sensor described in Patent Document 2 detects the electrical conduction of nerves stimulated by electromagnetic therapy, and does not directly detect high-frequency magnetic field strength or probe abnormalities, nor does it specify a means of communication. Furthermore, the coil and sensor are mainly provided separately, and the connections to the control unit are also made by separate wiring. Therefore, the problem of housing the communication signal line between the probe and the main unit and the wiring for supplying high-frequency current within the same signal cable has not been considered.

[0009] Incidentally, electronic devices such as magnetic therapy equipment can malfunction or fail due to electromagnetic noise. In particular, magnetic therapy equipment is electronic equipment that irradiates the affected area with magnetic fields generated by high-frequency coils and low-frequency coils, respectively. Therefore, malfunctions such as malfunctions or failures in magnetic therapy equipment can sometimes lead to accidents that put patients in danger. Consequently, countermeasures against electromagnetic noise are extremely important for the normal and safe operation of magnetic therapy equipment.

[0010] From this perspective, magnetic therapy devices are required to be electromagnetically compatible (EMC). Specifically, EMC is defined as "the ability of a device or system to function satisfactorily in the electromagnetic environment in which it exists, without causing unacceptable electromagnetic interference to anything in that environment" (JIS C 60050-161, IEV terminology related to EMC). Establishing EMC in magnetic therapy devices includes measures against electromagnetic emissions and electromagnetic susceptibility (establishment of immunity). Immunity also includes measures against electrostatic discharge (ESD). Furthermore, the standards for electromagnetically compatible (EMC) devices for medical electronic equipment have been replaced by standards for electromagnetic interference (EMD).

[0011] Here, electromagnetic emission countermeasures are measures to prevent magnetic therapy devices from generating electromagnetic noise that adversely affects other electronic devices. Electromagnetic susceptibility (EMS) countermeasures are measures to ensure that magnetic therapy devices operate normally even when subjected to external electromagnetic noise. In other words, magnetic therapy devices need to maintain an environment resistant to magnetic noise by implementing both electromagnetic emission countermeasures and electromagnetic susceptibility (EMS) countermeasures. Electromagnetic noise generated from noise sources of electronic devices such as magnetic therapy devices can be divided into two types depending on how the electromagnetic noise is transmitted: differential (normal) mode noise and common mode noise. Therefore, electromagnetic susceptibility (EMS) countermeasures must address both of these modes of noise.

[0012] On the other hand, static electricity is generated when the human body comes into contact with a magnetic therapy device, and a discharge of this static electricity occurs. The voltage generated by this phenomenon (electrostatic discharge surge (ESD)) is several thousand volts or more, and such high-voltage pulses can penetrate the inside of the magnetic therapy device, causing malfunction or damage to the IC circuit built into the device. In order to prevent static electricity from entering the inside of the magnetic therapy device, it is necessary to suppress and eliminate electrostatic discharge surges (ESD).

[0013] In other words, magnetic therapy devices require electrostatic discharge (ESD) surge (ESD) countermeasures to suppress and eliminate ESD. ESD countermeasures are necessary for all components and locations where the human body comes into contact with the magnetic therapy device. Specifically, components and locations requiring ESD countermeasures include USB output terminals, LAN and other inlet connectors that users plug and unplug, and the operation buttons of the magnetic therapy device. For this reason, standards for ESD countermeasures that magnetic therapy devices must meet have been established.

[0014] This invention has been made in view of these technical circumstances, and aims to provide a magnetic therapy device that is excellent in countermeasures against electromagnetic interference (EMD), increases the output of high-frequency signals, and can obtain the necessary therapeutic effect to treat pain in the affected area. [Means for solving the problem]

[0015] To solve the above problems, the magnetic therapy device of the present invention generates a biostimulation signal wave, and treats pain in a affected area by irradiating 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 and around the affected area, comprising a device body having a first insulating film between a casing equipped with a liquid crystal display cover and a liquid crystal display, and a probe formed separately from the device body, wherein the first insulating film has a thin metal film made of a conductive metal on the surface facing the liquid crystal display.

[0016] Furthermore, it is considered that a more preferable solution for the magnetic therapy apparatus of the present invention is that (a) the metal thin film is formed such that the first insulating film is exposed to the liquid crystal display, (b) the metal thin film is in the shape of a rectangular frame formed to surround the outer edge of the first insulating film, (c) the conductive metal includes at least one metal selected from aluminum, copper, silver, and gold, (d) the thickness of the first insulating film is 10 to 100 μm, (e) the total light transmittance of the first insulating film is 70% or more, and (f) a second insulating film is provided between the metal thin film and the liquid crystal display, and the metal thin film is integrally formed by being sandwiched between the first insulating film and the second insulating film. [Effects of the Invention]

[0017] The present invention provides a magnetic therapy device that is excellent in countermeasures against electromagnetic interference (EMD). Specifically, since the first insulating film of the magnetic therapy device of the present invention has a thin metal film made of a conductive metal on the surface facing the liquid crystal display, it can effectively prevent electromagnetic noise from entering the liquid crystal display from the outside and satisfy the requirements for electromagnetic interference (EMD). Moreover, even in magnetic therapy devices where the metal part of the liquid crystal display cannot be in contact with the frame ground in order to protect the operator or patient, the magnetic therapy device of the present invention can effectively prevent electromagnetic noise from entering the liquid crystal display from the outside.

Modes for Carrying Out the Invention

[0019] Hereinafter, the magnetic therapy device according to the present embodiment will be described in detail based on the drawings. Each drawing is schematic and may be different from the actual one. Further, the following embodiments illustrate devices for embodying the technical idea of the present invention, and their configurations are not limited to the following. That is, the technical idea of the present invention can be variously modified within the technical scope described in the claims.

[0020] FIG. 1 is a perspective view showing the overall appearance of a magnetic therapy device 100 according to an embodiment of the present invention. As shown in FIG. 1, the magnetic therapy device 100 according to the present embodiment includes a device main body 101, a probe 102, a communication cable 103 connecting the probe 102 to the device main body 101, and a power cable (not shown) detachably inserted and attached to the device main body 101.

[0021] The magnetic therapy device 100 of the present embodiment generates a signal wave for biological stimulation, irradiates a magnetic field for stimulating a diseased part, which is generated in a coil by the signal wave for biological stimulation, onto the diseased part of a living body, and stimulates cells and nerves in the diseased part and the periphery of the diseased part, thereby treating the pain of the diseased part. The magnetic therapy device 100 is a magnetic therapy device excellent in electromagnetic interference (EMD) countermeasures. The magnetic therapy device 100 includes a device main body 101 having a first insulating film 111 between a casing 104 provided with a liquid crystal display cover and a liquid crystal display 110 described later, and a probe 102 formed separately from the device main body 101. The first insulating film 111 has a metal thin film 113 made of a conductive metal on the surface facing the liquid crystal display 110. Hereinafter, each member included in the magnetic therapy device 100 of the present embodiment will be described.

[0022] The device main body 101 included in the magnetic therapy device 100 includes a resin casing 104 and a touch input type display screen 105 housed obliquely upward in the casing 104 and exposed from an opening 104a on the front surface of the casing 104.

[0023] The magnetic therapy device 100 includes a probe 102 formed separately from the device main body 101 and connected to the signal wave output unit by a communication cable 103. The probe 102 is a member for applying the magnetic therapy device 100 of the present embodiment to a diseased part of a living body, generating a magnetic field, and irradiating the diseased part with the magnetic field to treat the pain of the diseased part. The magnetic therapy device 100 may include at least one probe 102, and the number of probes 102 may be increased as needed.

[0024] The magnetic therapy device 100 of this embodiment has a probe 102 that is separate from the main device body 101. Therefore, by applying only the probe 102 to the affected area of ​​the body, the magnetic field generated by the main device body 101 can be irradiated onto the affected area. Here, the probe 102 does not house the signal wave generation unit and the power supply unit. Therefore, the probe 102 can be designed to be more compact than the main device body 101. As a result, when using the magnetic therapy device 100, the probe 102 is not bulky, does not get caught on clothing, and does not fall off the affected area.

[0025] Figure 2 is a front view showing the external appearance of the main body of the magnetic therapy device according to this embodiment. As shown in Figure 2, an alarm stop button 107 and a power switch button 108 are provided on the left and right sides below the opening 104a on the front of the casing 104 of the device body 101. Further below the alarm stop button 107 and the power switch button 108, three sockets 109 for plugging in a communication cable 103 are provided side by side to allow connection of three probes 102 to the device body 101.

[0026] Figure 3 is a schematic rear view showing the external appearance of the liquid crystal display (LCD) provided in the magnetic therapy device of this embodiment. Figure 3(a) is a front perspective view showing the external appearance of the device body provided in the magnetic therapy device of the above embodiment. As shown in Figure 3(a), the device body 101 includes a liquid crystal display (LCD) 110 inside the casing 104 which is the front cover and the casing 104 which forms the back of the device body 101. Furthermore, a first insulating film 111 is installed between the liquid crystal display (LCD) 110 and the casing 104 which has a liquid crystal display cover.

[0027] Figure 3(b) is a side view showing the external appearance of the main body of the magnetic therapy device according to the above embodiment. As shown in Figure 3(b), a silicone tube 112 is placed between the casing 104 equipped with a liquid crystal display cover and the first insulating film 111. The silicone tube 112 seals the space between the first insulating film 111 and the casing 104 equipped with a liquid crystal display cover.

[0028] Figure 4 is a schematic diagram showing the external appearance of the liquid crystal display (LCD) provided in the magnetic therapy device of the above embodiment. Figure 4(a) is a schematic rear view showing the external appearance of the liquid crystal display (LCD) provided in the magnetic therapy device of the above embodiment. As shown in Figure 4(a), the device body 101 is assembled by fitting together the casing 104, silicone tube 112, first insulating film 111, and liquid crystal display (LCD) 110 in the direction from the casing 104, which is the front cover, toward the liquid crystal display (LCD) 110, excluding the casing 104 that forms the rear of the device body 101.

[0029] Figure 4(b) is a cross-sectional view AA showing the appearance of the liquid crystal display (LCD) provided in the magnetic therapy device of the above embodiment. As shown in Figure 4(b), the first insulating film 111 has a thin metal film 113 made of a conductive metal on the surface facing the liquid crystal display (LCD) 110. Here, the metal foil film 113 is formed so that the first insulating film 111 is exposed to the liquid crystal display (LCD) 110. Specifically, the thin metal film 113 may be in the shape of a rectangular frame formed to surround the outer edge of the first insulating film 111. By forming the thin metal film 113 so that the first insulating film 111 is exposed to the liquid crystal display (LCD) 110 in this way, the display of the liquid crystal display (LCD) 110 is not obscured, and malfunctions of the touch panel of the touch input type display screen 105 can be prevented. A silicone tube 112 for sealing between the liquid crystal display (LCD) 110 and the casing 104 equipped with the liquid crystal display cover is provided on the back of the casing 104 equipped with the liquid crystal display cover and is tightly fitted into a casing groove 114 for the silicone tube that is formed along the inside of the rectangular frame-shaped liquid crystal display cover.

[0030] Figure 5 is an enlarged cross-sectional view showing the relationship between the liquid crystal display (LCD) and the liquid crystal display (LCD) cover in the magnetic therapy device of the above embodiment. As shown in Figure 5, the sides of the liquid crystal display (LCD) 110 are covered by a casing 104 equipped with a liquid crystal display cover having a rectangular frame shape. Between the liquid crystal display (LCD) 110 and the casing 104 equipped with a liquid crystal display cover, a first insulating film 111 is installed, which has a thin metal film 113 made of a conductive metal on the surface facing the liquid crystal display (LCD) 110. The space formed between the liquid crystal display (LCD) 110 and the casing 104, which includes the first insulating film 111 and the liquid crystal display cover, is sealed by a silicone tube 112 that is tightly fitted into a casing groove 114 for a silicone tube, which is formed along the inside of the outer edge of the liquid crystal display cover on the back of the casing 104.

[0031] The silicone tube 112 has a hollow structure with a hollow interior. In other words, the silicone tube 112, which has a hollow structure, is used as a material to seal between the liquid crystal display (LCD) 110 and the liquid crystal display cover integrated with the casing 104. Here, because the silicone tube 112 has a hollow structure, it is easily deformed. When the liquid crystal display (LCD) 110 is press-fitted into the casing 104 equipped with the liquid crystal display cover, the silicone tube 112 is compressed and deformed along the shape of the casing groove 114 for the silicone tube, which is formed along the inside of the liquid crystal display cover integrated with the casing 104. That is, since the silicone tube 112 employs a hollow structure with a hollow interior, it deforms to completely seal the space formed between the liquid crystal display (LCD) 110 and the liquid crystal display cover integrated with the first insulating film 111 and the casing 104. The radial cross-sectional shape of the silicone tube 112 changes from an annular shape to an elliptical annular shape when the liquid crystal display (LCD) 110 is press-fitted into the casing 104 equipped with the liquid crystal display cover. The hollow portion forming the hollow structure of the silicone tube 112 may be compressed.

[0032] The silicone tube 112 has a rectangular frame shape and can be appropriately set to match the outer frame shape of the liquid crystal display cover integrated with the casing 104. The shape of the silicone tube 112 can be appropriately set; for example, the inner diameter of the silicone tube 112 can be set in the range of 0.1 to 2.0 mm. The outer diameter of the silicone tube 112 can be set in the range of 0.4 to 3.0 mm. The thickness of the silicone tube 112 can be set in the range of 0.2 to 1.5 mm. Thus, the main body 101 of the magnetic therapy device 100 of this embodiment can completely seal the space formed between the first insulating film 111 and the casing 104 equipped with a liquid crystal display cover using a hollow silicone tube 112. As a result, static electricity discharged from the outside can be effectively prevented from entering the liquid crystal display (LCD) 110 provided in the main body 101 of the magnetic therapy device 100 of this embodiment. Consequently, the magnetic therapy device 100 of this embodiment has excellent electromagnetic interference (EMD) countermeasures.

[0033] As shown in Figure 5, a first insulating film 111 is installed in the gap formed between the liquid crystal display (LCD) 110 and the casing 104 equipped with a liquid crystal display cover. The first insulating film 111 has a thin metal film 113 made of a conductive metal on the surface facing the liquid crystal display (LCD) 110. The first insulating film 111 is used as a component for electromagnetic interference (EMD) countermeasures in the magnetic therapy device 100 of this embodiment.

[0034] Furthermore, a thin metal film 113 is formed on the surface of the first insulating film 111 that faces the liquid crystal display (LCD) 110. The thin metal film 113 is used as an electromagnetic compatibility (EMC) countermeasure for the magnetic therapy device 100 in this embodiment. The thin metal film 113 formed on the first insulating film 111 faces the liquid crystal display (LCD) 110. By positioning the thin metal film 113 facing the liquid crystal display (LCD) 110 in this way, the liquid crystal display (LCD) 110 is shielded, preventing electromagnetic noise from being radiated from outside the magnetic therapy device 100 to the device body 101. In other words, the thin metal film 113 shields the liquid crystal display (LCD) 110, preventing electromagnetic noise from entering the liquid crystal display (LCD) 110 from outside the magnetic therapy device 100.

[0035] The main body 101 of the magnetic therapy device 100 of this embodiment employs a structure in which a first insulating film 111 is installed between the liquid crystal display (LCD) 110 and the casing 104 equipped with a liquid crystal display cover, and a thin metal film 113 made of a conductive metal is formed on the surface of the first insulating film 111 facing the liquid crystal display (LCD) 110, thereby suppressing static electricity and preventing electromagnetic noise from entering the liquid crystal display (LCD) 110.

[0036] The first insulating film 111 is formed to completely cover the screen of the liquid crystal display (LCD) 110. The shape of the first insulating film 111 can be appropriately set to match the shape of the screen of the liquid crystal display (LCD) 110, and is larger than the screen of the liquid crystal display (LCD) 110 so as to maintain the insulating properties of the device body. The thickness of the first insulating film 111 is preferably 10 to 100 μm. A thickness of 10 μm or more is preferable because it can sufficiently prevent electromagnetic noise from entering from the liquid crystal display (LCD) 110. A thickness of 100 μm or less is preferable because it does not interfere with the visibility of the liquid crystal display (LCD) 110.

[0037] The first insulating film 111 is not particularly limited as long as it is made of a material with excellent insulating properties and processability. Examples of the first insulating film 111 include polyethylene terephthalate (PET), polycarbonate (PC), polypropylene (PC), polyethylene (PE), polyester, and low-pressure transparent polyurethane. Among these, polyethylene terephthalate (PET) and polycarbonate (PC) can be preferably used from the viewpoint of flame retardancy for the magnetic therapy device 100.

[0038] The transparency of the first insulating film 111 is preferably such that the total light transmittance is 70% or more. A total light transmittance of 70% or more for the first insulating film 111 is preferable because it can improve the visibility of the liquid crystal display (LCD) 110. Here, total light transmittance is defined, for example, in JIS K7375:2008. Specifically, JIS K7375:2008 specifies how to determine the total light transmittance and total light reflectance in the visible region for transparent, translucent, and opaque plastics in the form of plates and films, and specifies how to determine the total light transmittance of transparent plastic materials with a thickness not exceeding 10 mm.

[0039] The first insulating film 111 is characterized by having a thin metal film 113 made of a conductive metal on the surface facing the liquid crystal display (LCD) 110. The conductive metal constituting the thin metal film 113 preferably contains at least one metal selected from aluminum, copper, silver, and gold. These conductive metals are materials that can reduce electromagnetic noise due to eddy currents, but only in the case of high-frequency noise generated by the high-frequency biostimulation signal wave with a first frequency of several tens of MHz or more, for example, within a predetermined range with a center frequency of 250 MHz, which is used in the magnetic therapy device 100 of this embodiment.

[0040] In other words, the main body 101 of the magnetic therapy device 100 of this embodiment is characterized by the adoption of a specific material having high conductivity as the conductive metal formed in the first insulating film 111. The conductive metal constituting the metal thin film 113 may be one metal selected from aluminum, copper, silver, and gold, or it may be an alloy composed of a combination of multiple types of these metals.

[0041] The thickness of the metal thin film 113 should be such that it can shield electromagnetic noise generated from the liquid crystal display (LCD) 110, and is preferably 1.0 to 100 μm. A thickness of 1.0 μm or more is preferable because it can effectively shield electromagnetic noise generated from the liquid crystal display (LCD) 110. A thickness of 100 μm or less is preferable because no air layer remains at the step, and the metal thin film 113 can be easily formed on the first insulating film 111.

[0042] The metal foil film 113 is formed on the surface of the first insulating film 111 facing the liquid crystal display (LCD) 110, and it is necessary that the first insulating film 111 is exposed to the liquid crystal display (LCD) 110. The shape of the metal thin film 113 may be a rectangular frame shape formed to surround the outer edge of the first insulating film 111. That is, the metal foil film 113 is formed on the surface of the first insulating film 111 facing the liquid crystal display (LCD) 110, and can be formed only on the outer edge of the first insulating film 111, resulting in a so-called windowed shape.

[0043] Electromagnetic noise entering the main body 101 of the device from the outside can be classified into radiated emission electromagnetic noise that travels through space and conducted emission electromagnetic noise that travels through communication cables and their components such as metal frames, depending on their propagation mode. In the main body 101 of the magnetic therapy device 100 described above, the liquid crystal display (LCD) 110 is shielded by a thin metal film 113 formed on the first insulating film 111, so effective countermeasures against both types of electromagnetic noise can be taken.

[0044] Furthermore, since the first insulating film 111 provided on the main body 101 of the magnetic therapy device 100 in this embodiment is provided across the entire surface of the liquid crystal display (LCD) 110, it can prevent electromagnetic noise from entering from outside the main body 101. By preventing electromagnetic noise from entering from outside the main body 101, the first insulating film 111 prevents malfunction of the electronic circuits built into the main body 101.

[0045] A thin metal film 113 made of a conductive metal is placed on the surface of the first insulating film 111 facing the liquid crystal display (LCD) 110, shielding the liquid crystal display (LCD) 110. Shielding is an effective measure against electromagnetic interference (EMD). In the magnetic therapy device 100 of this embodiment, preventing external electromagnetic noise from entering the liquid crystal display (LCD) 110 is of utmost importance in order to reliably obtain the shielding effect of the thin metal film 113.

[0046] From this perspective, in the magnetic therapy device 100 of this embodiment, the device body 101 completely seals the casing 104 equipped with a liquid crystal display cover and the liquid crystal display (LCD) 110 with a silicone tube 112. In the magnetic therapy device 100 of this embodiment, by completely sealing the liquid crystal display cover and the liquid crystal display (LCD) 110 with the silicone tube 112, electromagnetic noise can be prevented from entering from outside the device body 101, and electromagnetic interference (EMD) countermeasures can be effectively taken by using a metal thin film 113 made of conductive metal on the surface facing the first insulating film 111 and the liquid crystal display (LCD) 110.

[0047] The magnetic therapy device 100 of this embodiment has a first insulating film 111 on the surface facing the liquid crystal display (LCD) 110 built into the device body 101, on which a thin metal film 113 made of a conductive metal is formed. This allows electromagnetic noise to enter the liquid crystal display (LCD) 110 without the metal parts of the LCD 110 coming into contact with the frame ground. Furthermore, the magnetic therapy device 100 of this embodiment may have a second insulating film between the thin metal film 113 and the liquid crystal display (LCD) 110. That is, the thin metal film 113 may be sandwiched between the first insulating film 111 and the second insulating film to form a single unit, thus employing a so-called sandwich structure. By adopting this sandwich structure of the device body 101 consisting of the thin metal film 113, the first insulating film 111, and the second insulating film, electromagnetic noise to enter the liquid crystal display (LCD) 110 can be further suppressed. In other words, the main body 101 of the magnetic therapy device 100 of this embodiment employs a first insulating film 111 with a thin metal film 113 made of a conductive metal formed on the surface facing the liquid crystal display (LCD) 110, or the first insulating film 111 and a second insulating film, thereby effectively preventing electromagnetic waves from entering the liquid crystal display (LCD) 110 and effectively providing countermeasures against electromagnetic interference (EMD). That is, the main body 101 of the magnetic therapy device 100 of this embodiment has an insulating film with a thin metal film 113 made of a conductive metal formed on the surface facing the liquid crystal display (LCD) 110 built into the main body 101, which provides excellent countermeasures against electromagnetic interference (EMD).

[0048] Although the above has been described based on the illustrated embodiments, the magnetic therapy device of this invention is not limited to the embodiments described above and can be modified as appropriate within the scope of the claims. That is, modifications may be made to the main body 101 of the magnetic therapy device 100 of this embodiment to generate a magnetic field for stimulating the affected area, which is generated in the coil using a biostimulation signal wave.

[0049] For example, the main body 101 of the magnetic therapy device 100 of this embodiment may have a signal wave output unit that generates and outputs a biostimulation signal wave of a first frequency, and may also have a first coil connected to the signal wave output unit by a communication cable, to which the biostimulation signal wave of the first frequency output from the signal wave output unit is supplied. Furthermore, in the main body 101 of the magnetic therapy device 100 of this embodiment, the frequency fluctuation of the biostimulation signal wave of the first frequency output from the signal wave output unit may be within a predetermined range with a center frequency of 250 MHz. In addition, the main body 101 of the magnetic therapy device 100 of this embodiment may have a second coil to which the signal wave output unit generates and outputs a biostimulation signal wave of a second frequency output from the signal wave output unit is supplied.

[0050] By setting the first frequency biostimulation signal wave to a high-frequency biostimulation signal wave centered at 250 MHz, a high-frequency alternating magnetic field is generated from this high-frequency signal wave. The generated high-frequency alternating magnetic field has a strong effect in activating damaged sensory cells and inducing neurotrophic factors, so it is expected to enhance the effect of reducing nerve damage in the affected area. Furthermore, by setting the second frequency biostimulation signal wave to a low-frequency biostimulation signal wave between 1 kHz and 3 kHz, a low-frequency alternating magnetic field is generated from this low-frequency signal wave. The generated low-frequency alternating magnetic field is particularly likely to travel through sensory nerves to the brain via the spinal cord's dorsal horn, so it is expected to bring about greater analgesic and relaxing effects, as well as other nerve damage reduction effects.
