Summary of the Invention

Problem to be Solved by the Invention

[0005] By the way, in such a magnetic therapy device that generates a biological stimulation signal wave, reducing the level of harmonic noise of high-frequency signals so as not to cause influences such as malfunction to other devices and equipment is required by, for example, the international standard such as EN55011 (Industrial, scientific and medical equipment - Radio frequency interference characteristics - Limit values and measurement methods).

[0006] However, in conventional magnetic therapy devices as described above, a single-frequency high-frequency signal is used as the biostimulation signal wave to the coil. As a result, increasing the output of the biostimulation signal wave also increases the level of harmonic noise, making it difficult to meet EMI standards while obtaining sufficient therapeutic effects.

[0007] Therefore, this invention aims to provide a magnetic therapy device that meets EMI standards while increasing the output of biostimulatory signal waves to obtain sufficient therapeutic effects. [Means for solving the problem]

[0008] The magnetic therapy device of this invention generates a biostimulation signal wave, and irradiates the affected area of ​​the body with a magnetic field for stimulating the affected area generated by the biostimulation signal wave in a coil, thereby stimulating the cells and nerves in and around the affected area and treating pain in the affected area. A device body having a signal wave output unit that generates and outputs a first signal wave for biological stimulation, A probe, formed separately from the main body of the device, has a first coil connected by a signal cable to the signal wave output section and supplied with the first signal wave output from the signal wave output section, Equipped with, The signal wave output unit is characterized by varying the frequency of the first signal wave within a predetermined range. [Effects of the Invention]

[0009] In the magnetic therapy device of this invention, the main body of the device has a signal wave output unit that generates and outputs a first signal wave, for example, a high-frequency signal wave for biostimulation, and a first coil of a probe formed separately from the main body of the device is connected to the signal wave output unit by a signal cable and is supplied with the first signal wave output from the signal wave generation unit, and generates a first alternating magnetic field for stimulating the affected area with the first signal wave.

[0010] Therefore, according to the magnetic therapy device of this invention, by applying a probe, which is separate from the main body of the device, to the affected area of ​​the body, the first alternating magnetic field generated by the first coil is irradiated onto the affected area, stimulating the cells and nerves in and around the affected area. This stimulation is expected to activate the damaged nerves in the affected area, and through self-repair, reduce nerve damage in the affected area.

[0011] Furthermore, according to the magnetic therapy device of this invention, the signal wave output unit of the device body varies the frequency of the first signal wave for biostimulation within a predetermined range. As a result, the QP (quasi-peak) value of the harmonic noise is lower than when the frequency of the first signal wave is kept constant. For example, a first signal wave for biostimulation with high intensity within EMI standards can be supplied to the first coil to generate a first alternating magnetic field for stimulating the affected area with high intensity.

[0012] In the magnetic therapy device of this invention, the frequency fluctuation of the first signal wave may be within a predetermined range with a center frequency of 250 MHz, preferably within 250 MHz ± 20%, and more preferably within 250 MHz ± 10%. In this case, the first alternating magnetic field at the center of 250 MHz has a high effect in activating damaged nerves, and it is expected that the effect of reducing nerve damage in the affected area through self-repair will be enhanced.

[0013] Furthermore, in the magnetic therapy device of this invention, the signal wave output unit may also generate and output a second signal wave for biostimulation, and the probe may have a second coil connected to the signal wave output unit by a signal cable and supplied with the second signal wave output from the signal wave output unit. In this way, the stimulation applied to the affected area by irradiating it with a second alternating magnetic field for stimulating the affected area, generated by the second coil using, for example, a low-frequency second signal wave for biostimulation, 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.

[0014] On the other hand, in the magnetic therapy device of this invention, the signal wave output unit may also generate a second signal wave for biostimulation, and generate and output the first signal wave by frequency modulating the fundamental signal wave with the second signal wave. In this way, the first alternating magnetic field for stimulating the affected area generated by the first coil by the first signal wave for biostimulation, which is frequency modulated by the second signal wave for biostimulation supplied from the signal wave output unit, stimulates the cells and nerves in and around the affected area. This is expected to activate the damaged nerves in the affected area more than in the absence of frequency modulation, and to further reduce nerve damage in the affected area through self-repair.

[0015] Furthermore, in the magnetic therapy device of this invention, the signal wave output unit also generates and outputs a second signal wave for biostimulation, the probe is connected to the signal wave output unit by a signal cable and also has a second coil to which the second signal wave is supplied from the signal wave output unit, and the signal wave output unit generates the first signal wave by frequency modulating the fundamental signal wave with the second signal wave and outputs it separately from the second signal wave. In this way, it is expected that the second alternating magnetic field for stimulating the affected area generated by the second coil with the second signal wave for biostimulation will bring analgesic and relaxing effects, and the first alternating magnetic field for stimulating the affected area generated by the first coil with the first signal wave for biostimulation, which is obtained by frequency modulating the fundamental signal wave with the second signal wave for biostimulation, will further reduce nerve damage in the affected area.

[0016] Furthermore, in the magnetic therapy device of this invention, the frequency of the second signal wave may be 1 kHz or higher and 3 kHz or lower. In this case, the stimulation from the second alternating magnetic field of 1 kHz or higher and 3 kHz or lower generated in the second coil by the second signal wave for biostimulation is particularly likely to reach the brain from the spinal cord dorsal horn via sensory nerves, and is therefore expected to bring about greater analgesic and relaxing effects, as well as other neurological disorder reduction effects.

MODE FOR CARRYING OUT THE INVENTION

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing the overall external appearance of a magnetic therapy apparatus according to an embodiment of the present invention; FIG. 2 and FIG. 3 are a front view and a side view respectively showing the external appearance of the device main body of the magnetic therapy apparatus according to the embodiment; FIG. 4 and FIG. 5 are cross-sectional views respectively showing the A-A cross-section and the B-B cross-section in FIG. 3 of the magnetic therapy apparatus according to the embodiment.

[0019] As shown in Figure 1, the magnetic therapy device of this embodiment comprises a device body 1, a probe 2, a signal cable 3 for connecting the probe 2 to the device body 1, and a power cable (not shown) that is detachably plugged into and attached to the device body 1. As shown in Figures 2 to 5, the device body 1 mainly comprises a resin casing 4, a touch input display 5 housed diagonally upward within the casing 4 and exposed from an opening 4a on the front of the casing 4, two printed circuit boards 6 and 7 housed diagonally downward behind the display 5 within the casing 4 and arranged left and right when viewed from the rear of the device body, two AC-DC converters 8 and 9 housed horizontally within a protrusion 4b on the lower rear side of the casing 4 and arranged left and right when viewed from the rear of the device body, and a battery 10 housed below the AC-DC converters 8 and 9 within the protrusion 4b on the lower rear side of the casing 4.

[0020] Furthermore, an alarm stop button and a power switch button are provided on the left and right sides of the lower part of the opening 4a on the front of the casing 4 of the device body 1. Below these buttons, three sockets for plugging in the signal cable 3 are provided side by side to allow connection of the three probes 2 to the device body 1.

[0021] Figure 6 is a block diagram showing the configuration of the magnetic therapy device of this embodiment in functional blocks. As shown in this figure, the magnetic therapy device of this embodiment comprises a device body 1, a probe 2, and a signal cable 3. Functionally, the device body 1 has a signal wave output unit 13, a screen control unit 14, and a power supply unit 15. In this embodiment, the signal wave output unit 13 is mainly configured using a plurality of central processing units (CPUs) (not shown) on the printed wiring board 6 on the left side. The basic high-frequency signal generation unit 13a generates a basic high-frequency signal of 250 MHz as a basic signal wave, and the basic high-frequency signal shift unit 13b shifts (varies) this basic high-frequency signal appropriately at regular intervals, for example, every 0.00014 seconds (i.e., approximately 7000 times / second), within a range of 225 MHz to 275 MHz, which is ±10% of 250 MHz as the center frequency, while excluding the frequency band used in aircraft life-saving radios, and outputs the shifted basic high-frequency signal as a first signal wave to the basic high-frequency signal frequency modulation unit 13c.

[0022] Here, the basic high-frequency signal generation unit 13a is configured using, for example, a direct digital synthesizer (DDS), and can generate a basic signal of any frequency from a range of, for example, 200 MHz to 300 MHz, including the range of 225 MHz to 275 MHz mentioned above. The basic high-frequency signal shifting unit 13b sets the target frequency of the shift using, for example, random numbers, so that the frequency distribution is uniform.

[0023] The signal wave output unit 13 also reads a magnetic signal pattern, including sound source signals such as music, which is pre-recorded on an SD card (not shown) inserted in a card slot on the left printed circuit board 6, from the SD card using the magnetic signal pattern reading unit 13d and supplies it to the biostimulation low-frequency signal generation unit 13e. The biostimulation low-frequency signal generation unit 13e generates a biostimulation low-frequency signal as a second signal wave from the frequency information (for example, 1kHz or higher and 3kHz or lower) of the magnetic signal pattern and outputs the biostimulation low-frequency signal to the basic high-frequency signal frequency modulation unit 13c.

[0024] The basic high-frequency signal frequency modulation unit 13c then frequency modulates a basic high-frequency signal, for example 250 MHz ± 10%, generated by the basic high-frequency signal generation unit 13a and frequency-shifted by the basic high-frequency signal shifting unit 13b, with a second signal wave, for example, a low-frequency biostimulation signal of 1 kHz or higher and 3 kHz or lower, generated by the low-frequency biostimulation signal generation unit 13e, and supplies it to the high-frequency biostimulation signal output unit 13f. The high-frequency biostimulation signal output unit 13f then amplifies and outputs the frequency-modulated first signal wave, the high-frequency biostimulation signal. Alternatively, the high-frequency biostimulation signal output unit 13f may amplitude modulate the frequency-modulated high-frequency biostimulation signal with the low-frequency biostimulation signal before amplifying and outputting it. Furthermore, the low-frequency biostimulation signal output unit 13g amplifies and outputs a second signal wave, for example, a low-frequency biostimulation signal of 1 kHz or higher and 3 kHz or lower, generated by the low-frequency biostimulation signal generation unit 13e. These operations in the signal wave output unit 13 are controlled by the operation state control unit 13h.

[0025] In this embodiment, the probe 2 houses a flexible printed circuit board (not shown) within a soft resin cover. A high-frequency coil 2a is formed on the flexible printed circuit board by printed wiring, and a low-frequency coil 2b is formed inside it. In addition, a magnetic detection coil is formed outside the high-frequency coil 2a. Furthermore, an operating state detection unit 2c is circuit-configured using a temperature detection element and a CPU mounted on the flexible printed circuit board. The high-frequency coil 2a generates a first alternating magnetic field, 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 13f via a signal cable 3. The low-frequency coil 2b generates a second alternating magnetic field, 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 13g via a signal cable 3.

[0026] The operating state detection unit 2c then detects the operating state of the signal wave output unit 13 and the state of the probe 2 based on the temperature of the high-frequency coil 2a and low-frequency coil 2b detected by the temperature detection element and the high-frequency or low-frequency magnetic intensity detected by the magnetic detection coil, based on the instruction signal provided by the operating state control unit 13h of the signal wave output unit 13 via the signal cable 3. Based on this signal, the operating state control unit 13h monitors the operation of the signal wave output unit 13, such as signal wave generation and output, and consequently the level of the alternating magnetic field generated by the high-frequency coil 2a and low-frequency coil 2b. If an abnormality is detected, an alarm sound is output from, for example, a speaker (not shown) built into the main body 1. The output of this alarm sound is stopped when the abnormal condition is resolved or when the alarm stop button on the front of the casing 4 of the main body 1 is operated. Furthermore, if the operation state control unit 13h detects an abnormality, it immediately stops the supply of a high-frequency signal for biostimulation from the high-frequency signal output unit 13f to the high-frequency coil 2a and the supply of a low-frequency signal for biostimulation from the low-frequency signal output unit 13g to the low-frequency coil 2b, in order to ensure the safety of the user of the magnetic therapy device.

[0027] In this embodiment, the screen control unit 14 is mainly configured on the right-side printed circuit board 7 using a graphics processing unit (GPU) or the like (not shown). The image display unit 14a reads screen information such as instruction buttons to be displayed on the liquid crystal display (LCD) 5a of the touch input display 5 from an SD card (not shown) that has been pre-recorded on the SD card inserted into the card slot on the right-side printed circuit board 7, and displays it on the LCD 5a. The instruction input unit 14b detects the position where the user's finger touches the touch panel 5b of the touch input display 5 from changes in static electricity at that position, and sends a signal to the operation state control unit 13h indicating instruction input by an operation button displayed on the LCD 5a corresponding to that touch position. Based on this instruction input signal, the operation state control unit 13h controls the operation of the signal wave output unit 13, such as signal wave generation and output, and consequently the alternating magnetic field generated by the high-frequency coil 2a and low-frequency coil 2b, according to the user's instructions.

[0028] The screen control unit 14 also creates a log that records the instruction input to the instruction input unit 14b via the operation buttons displayed on the LCD 5a and the operating status of the signal wave output unit 13 at that time. This log information is stored in a USB memory (not shown) that is inserted into a USB memory slot 11, which is located between the AC-DC converters 8 and 9 in the lower rear protrusion 4b of the casing 4 and covered with an openable and closable lid, and is removable from the top side of the protrusion 4b. Furthermore, the image display unit 14a has a clock function that displays the time on the LCD 5a, and this clock function is maintained by a button battery (not shown) mounted in a battery holder on the right-side printed circuit board 7.

[0029] In this embodiment, the power supply unit 15 is circuit-configured using a power control unit 15a, which mainly has a CPU (not shown), a normal switching regulator, and a three-terminal regulator mounted on the left-side printed circuit board 7, and two AC-DC converters 8 and 9 located in the rear lower protrusion 4b of the casing 4. The power control unit 15a supplies 100V commercial AC power from a power cable (not shown), which is detachably plugged into a power socket 12 located facing backward in the rear lower protrusion 4b of the casing 4, to the two AC-DC converters 8 and 9. The switching control of the AC-DC converters 8 and 9 converts the 100V AC into DC of a predetermined voltage that has been stabilized. By connecting these DC voltages in series, a DC voltage corresponding to the output voltage of the battery 10 is obtained to charge the battery 10. The power control unit 15a then steps down and stabilizes this DC voltage and supplies it as a DC power supply of the required voltage to the signal wave output unit 13 and screen control unit 14 of the device body 1 and the operating state detection unit 2c of the probe 2.

[0030] Furthermore, when the power cable is not connected or when 100V commercial AC power is not supplied from the power cable, the power supply unit 15 steps down and stabilizes the DC voltage from the battery 10 using the switching regulator and three-terminal regulator of the power control unit 15a, and supplies it as a DC power supply of the necessary voltage to the signal wave output unit 13 and screen control unit 14 of the device body 1 and the operating state detection unit 2c of the probe 2, thereby enabling the magnetic therapy device to be used as a portable device.

[0031] In this embodiment of the magnetic therapy device, the signal wave output unit 13 of the device body 1 has a basic high-frequency signal generation unit 13a, a basic high-frequency signal shift unit 13b, and a basic high-frequency signal frequency modulation unit 13c which generate a biostimulation high-frequency signal. The biostimulation high-frequency signal output unit 13f outputs this biostimulation high-frequency signal. The high-frequency coil 2a of the probe 2, which is formed separately from the device body 1, is connected to the biostimulation high-frequency signal output unit 13f of the signal wave output unit 13 by a signal cable 3. The probe is supplied with a biostimulation high-frequency signal output unit 13f, for example, with a center frequency of 250 MHz, and this biostimulation high-frequency signal generates a high-frequency alternating magnetic field for stimulating the affected area.

[0032] Therefore, according to the magnetic therapy device of this embodiment, by applying a probe 2, which is separate from the main body 1 of the device, to the affected area of ​​the living body, a high-frequency alternating magnetic field generated by the high-frequency coil 2a is irradiated onto the affected area, stimulating the cells and nerves in and around the affected area. This stimulation is expected to activate, for example, damaged nerves in the affected area, and through self-repair, reduce nerve damage in the affected area.

[0033] Furthermore, according to the magnetic therapy device of this embodiment, the basic high-frequency signal shift unit 13b of the signal wave output unit 13 of the device body 1 varies the frequency of the biostimulation high-frequency signal within a range of, for example, 250 MHz ± 10%. As a result, the QP (quasi-peak) value of the harmonic noise is lower than when the frequency of the biostimulation high-frequency signal is kept constant, and a high-intensity biostimulation high-frequency signal within EMI standards is supplied to the high-frequency coil 2a, thereby generating a high-intensity alternating high-frequency magnetic field for stimulating the affected area.

[0034] Figure 7 is a graph showing, as an example, the output signal level and second harmonic noise level of the biostimulation high-frequency signal output unit 13f when the basic high-frequency signal shift unit 13b of the magnetic therapy device of this embodiment performs a shift operation, and Figure 8 is a graph showing, as a comparative example, the output signal level and second harmonic noise level of the biostimulation high-frequency signal output unit 13f when the basic high-frequency signal shift unit 13b of the magnetic therapy device of this embodiment does not perform a shift operation.

[0035] As shown in Figure 7, in the embodiment of this invention, when the basic high-frequency signal shift unit 13b is in shift operation, the level of the biostimulation high-frequency output signal BHS with a frequency of 250 MHz ± 10% from the biostimulation high-frequency signal output unit 13f is approximately 54 dB in QP value, and the level of its second harmonic signal (noise) SHS with a frequency of 500 MHz ± 10% is 33.8 dB in QP value, which is below the upper limit of 37 dB in QP value of the EN55011:2009 / A1:2010 (CISPR 11:2009 / A1:2010) international standard Group 2 Class B-H.

[0036] On the other hand, as shown in Figure 8, in the comparative example of this invention, when the basic high-frequency signal shift unit 13b does not perform the shift operation, the level of the 250 MHz frequency biostimulation high-frequency output signal BHS from the biostimulation high-frequency signal output unit 13f becomes approximately 66 dB in QP value, and the level of its second harmonic signal (noise) SHS at 500 MHz frequency becomes approximately 39 dB in QP value, exceeding the upper limit of 37 dB in QP value of the EN55011:2009 / A1:2010 (CISPR 11:2009 / A1:2010) international standard Group 2 Class B-H.

[0037] These results confirm that, according to the magnetic therapy device of this embodiment, the basic high-frequency signal shift unit 13b of the signal wave output unit 13 of the device body 1 varies the frequency of the biostimulation high-frequency signal within a predetermined range. As a result, the QP value of harmonic noise is lower than when the frequency of the biostimulation high-frequency signal is kept constant, and a high-intensity biostimulation high-frequency signal within EMI standards is supplied to the high-frequency coil, thereby generating a high-intensity high-frequency alternating magnetic field for stimulating the affected area.

[0038] Furthermore, according to the magnetic therapy device of this embodiment, the biostimulation low-frequency signal generation unit 13e of the signal wave output unit 13 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 13g outputs the biostimulation low-frequency signal, and the low-frequency coil 2b of the probe 2 is connected to the biostimulation low-frequency signal output unit 13g of the signal wave output unit 13 by a signal cable 3 and supplied with a biostimulation low-frequency signal from the biostimulation low-frequency signal output unit 13g. As a result, the low-frequency alternating magnetic field for stimulating the affected area generated by the low-frequency coil 2b by the biostimulation low-frequency signal is irradiated onto the affected area, and the stimulation transmitted is transmitted through sensory nerves (Aβ fibers: touch) to the spinal cord dorsal horn and then 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.

[0039] Furthermore, according to the magnetic therapy device of this embodiment, the basic high-frequency signal modulation unit 13c 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 13 to generate a high-frequency signal for biostimulation, and the high-frequency signal output unit 13f for biostimulation supplies the frequency-modulated high-frequency signal for biostimulation to the high-frequency coil 2a of the probe 2. As a result, the cells and nerves in and around the affected area are stimulated by the high-frequency alternating magnetic field for stimulating the affected area generated by the high-frequency coil 2a 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 further reducing nerve damage in the affected area through self-repair.

[0040] Furthermore, according to the magnetic therapy device of this embodiment, the signal wave output unit 13 of the device body 1 also generates and outputs a low-frequency signal for biostimulation, the probe 2 is connected to the signal wave output unit 13 by a signal cable 3 and also has a low-frequency coil 2b that is supplied with a low-frequency signal for biostimulation from the signal wave output unit 13, and the signal wave output unit 13 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 coil 2b 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 coil 2a 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.

[0041] 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 coil 2b by this biostimulation low-frequency signal is particularly likely to reach the brain from the spinal cord dorsal horn via sensory nerves, thus providing a greater analgesic effect, relaxation effect, and other neurological disorder-reducing effects.

[0042] Although the above description is 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. For example, the basic high-frequency signal shifting unit 13b may shift the 250 MHz basic high-frequency signal within a range of, for example, 250 MHz ± 20%.

[0043] Furthermore, for example, the biostimulation low-frequency signal generation unit 13e may generate a biostimulation low-frequency signal 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]

[0044] Thus, according to the magnetic therapy device of this invention, the signal wave output unit of the device body generates and outputs a first signal wave for biostimulation, and the first coil of the probe, which is formed separately from the device body, is connected to the signal wave output unit by a signal cable and is supplied with the first signal wave output from the signal wave generation unit, and the first signal wave generates a first alternating magnetic field for stimulating the affected area. By applying the probe, which is formed separately from the device body, to the affected area, the first alternating magnetic field generated by the first coil is irradiated onto the affected area, stimulating the cells and nerves in and around the affected area. This stimulation is expected to activate, for example, damaged nerves in the affected area, and reduce nerve damage in the affected area through self-repair.

[0045] Furthermore, according to the magnetic therapy device of this invention, the signal wave output unit of the device body varies the frequency of the first signal wave for biostimulation within a predetermined range. As a result, the QP (quasi-peak) value of harmonic noise is lower than when the frequency of the first signal wave is kept constant. For example, a first signal wave of high intensity within EMI standards can be supplied to the first coil to generate a first alternating magnetic field of high intensity for stimulating the affected area.
