By the way, in a magnetic therapy apparatus that generates a biostimulation signal wave in this way, it is necessary to reduce the level of harmonic noise of high-frequency signals so as not to affect other devices and facilities by malfunctioning, etc., for example, according to EN55011 ( Industrial, Scientific and Medical Equipment-Radio Frequency Interference Characteristics-Limit Values and Measurement Methods) International standards, etc.

However, in the conventional magnetic therapy apparatus as described above, since a high-frequency signal of a single frequency is used as a signal wave for biostimulation to the coil, the level of harmonic noise increases as the output of the signal wave for biostimulation is increased. Therefore, it was difficult to satisfy the EMI standard while obtaining a sufficient therapeutic effect.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a magnetic therapy apparatus that satisfies the EMI standard while increasing the output of biostimulation signal waves to obtain sufficient therapeutic effects.

The magnetic therapy apparatus of the present invention generates a signal wave for biostimulation, irradiates a magnetic field for stimulating an affected part generated in a coil with the signal wave for biostimulation, and irradiates the affected part of a living body with cells and nerves in and around the affected part. A magnetic therapy device for treating pain in an affected area by stimulating the
a device main body having a signal wave output section for generating and outputting a first signal wave for biostimulation;
a probe formed separately from the device body, the probe having a first coil connected to the signal wave output section with a signal cable and supplied with the first signal wave output from the signal wave output section;
with
The signal wave output section is characterized by varying the frequency of the first signal wave within a predetermined range.

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

Therefore, according to the magnetic therapy apparatus of the present invention, by applying the probe separate from the apparatus main body to the affected part of the living body, the first alternating magnetic field generated by the first coil is irradiated to the affected part, and the affected part and the surroundings of the affected part are irradiated. It can be expected to stimulate cells and nerves, activate damaged nerves in the affected area by the stimulation, and reduce neuropathy in the affected area through self-repair.

Moreover, according to the magnetic therapy apparatus of the present invention, the signal wave output section of the apparatus body varies the frequency of the first signal wave for biostimulation within a predetermined range, so that the frequency of the first signal wave is kept constant. The QP (quasi peak) value of the harmonic noise is lower than the case, for example, a high intensity biostimulation first signal wave within the EMI standard is supplied to the first coil to achieve a high intensity affected area. A first alternating magnetic field for stimulation can be generated.

In the magnetic therapy apparatus of the present invention, the fluctuation of the frequency of the first signal wave is within a predetermined range with a center frequency of 250 MHz, preferably within a range of 250 MHz ±20%, more preferably within a range of 250 MHz ±10%. may In this way, since the first alternating magnetic field of 250 MHz at the center has a high effect of activating damaged nerves, self-healing can be expected to increase the effect of alleviating nerve damage in the affected area.

Further, in the magnetic therapy apparatus of the present invention, the signal wave output section also generates and outputs a second signal wave for biostimulation, and the probe is connected to the signal wave output section with a signal cable to output the signal. It may also have a second coil supplied with the second signal wave output from the wave output section. In this way, the stimulation applied by irradiating the affected area with the second alternating magnetic field for stimulation of the affected area generated by the second coil by the second signal wave of low frequency for biostimulation, for example, is applied to the sensory nerves (Aβ fibers: Since it reaches the brain (sensory area) from the dorsal horn of the spinal cord through the sense of touch), it is also expected that the brain recognizes the pleasure of touch and activates the descending antinociceptive system to bring about analgesic and relaxing effects.

On the other hand, in the magnetic therapy apparatus of the present invention, the signal wave output section also generates a second signal wave for biostimulation, and modulates the frequency of the fundamental signal wave with the second signal wave to generate the first signal wave. It may be generated and output. With this configuration, the first alternating signal wave for stimulating the affected part generated in the first coil by the first signal wave for biostimulation frequency-modulated by the second signal wave for biostimulation supplied from the signal wave output section By stimulating the cells and nerves in and around the affected area with a magnetic field, the damaged nerves in the affected area are more activated than in the absence of frequency modulation, and self-repair is expected to further reduce neuropathy in the affected area.

Further, in the magnetic therapy apparatus of the present invention, the signal wave output section also generates and outputs a second signal wave for biostimulation, and the probe is connected to the signal wave output section with a signal cable to output the signal wave. It also has a second coil to which the second signal wave is supplied from the output section, and the signal wave output section generates the first signal wave by frequency-modulating the fundamental signal wave with the second signal wave, It may be output separately from the second signal wave. In this way, the second alternating magnetic field for stimulating the affected part generated by the second coil by the second signal wave for biostimulation brings about an analgesic effect and a relaxing effect, and the second signal wave for biostimulation produces a basic signal. It can be expected that the first alternating magnetic field for stimulating the affected area generated by the first coil by the first signal wave for biostimulation, which is a frequency-modulated wave, can further reduce neuropathy in the affected area.

And in the magnetic therapy apparatus of this invention, the frequency of said 2nd signal wave may be 1 kHz or more and 3 kHz or less. In this way, the stimulation by the second alternating magnetic field of 1 kHz or more and 3 kHz or less generated in the second coil by the second signal wave for biostimulation reaches the brain from the dorsal horn of the spinal cord through sensory nerves. Since it is easy to use, it can be expected to bring about a higher analgesic effect and a neuropathy-reducing effect such as a relaxing effect.

In the unit 13b, the basic high frequency signal is generated within a range from 225 MHz to 275 MHz, which is ±10% of the center frequency of 250 MHz, for a certain period of time while excluding the frequency band used in the lifesaving radio for aircraft. For example, every 0.00014 seconds (that is, about 7000 times/second) is moderately shifted (varied), and the shifted basic high-frequency signal as the first signal wave is output to the basic high-frequency signal frequency modulation unit 13c. do.

The basic signal of the frequency can be oscillated, and the basic high-frequency signal shifter 13b sets the frequency to be shifted using, for example, random numbers so that the frequency distribution becomes uniform.

The signal wave output unit 13 also uses the magnetic signal pattern reading unit 13d to read a magnetic signal pattern including a sound source signal such as music recorded in advance on an SD card (not shown) mounted in a card slot on the left printed wiring board 6. It is read from the SD card and supplied to the biostimulation low-frequency signal generation unit 13e, and the biostimulation low-frequency signal generation unit 13e uses the frequency information (for example, 1 kHz or more and 3 kHz or less) of the magnetic signal pattern as a second signal wave. , and outputs the low frequency signal for biostimulation to the basic high frequency signal frequency modulation unit 13c.

Then, the basic high-frequency signal frequency modulating unit 13c converts the basic high-frequency signal of, for example, 250 MHz±10% generated by the basic high-frequency signal generating unit 13a and frequency-shifted by the basic high-frequency signal shifting unit 13b to the biostimulation low-frequency signal generating unit.

The biostimulation low-frequency signal output unit 13g amplifies and outputs the biostimulation low-frequency signal of, for example, 1 kHz or more and 3 kHz or less as the second signal wave generated by the biostimulation low-frequency signal generation unit 13e. .

Based on the instruction signal given from the operating state control section 13h of the signal wave output section 13 via the signal cable 3, the operating state detecting section 2c detects the high-frequency coil 2a and the low-frequency coil 2b detected by the temperature detecting element. The operating state of the signal wave output unit 13 and the state of the probe 2 are detected from the temperature and the high or low frequency magnetic intensity detected by the magnetic detection coil, and a signal indicating the state is output via the signal cable 3. It is input to the operating state control section 13 h of the section 13 . Based on the signal indicating this state, the operation state control unit 13h monitors the operation of the signal wave output unit 13 such as signal wave generation and output, and the level of the alternating magnetic field generated by the high-frequency coil 2a and the low-frequency coil 2b, thereby detecting an abnormality. In this case, for example, an alarm sound is output from a speaker (not shown) built in the apparatus main body 1 . The output of this alarm sound is stopped when the abnormal state is resolved or when the alarm stop button on the front surface of the casing 4 of the apparatus main body 1 is operated. In addition, immediately after detecting an abnormality, the operating state control unit 13h supplies a high-frequency signal for biostimulation from the high-frequency signal output unit 13f to the high-frequency coil 2a and performs biostimulation in order to ensure the safety of the user of the magnetic therapy apparatus.

In the magnetic therapy apparatus of this embodiment, the basic high-frequency signal generation section 13a, the basic high-frequency signal shift section 13b, and the basic high-frequency signal frequency modulation section 13c of the signal wave output section 13 of the device main body 1 produce the biostimulation high-frequency signal. is generated, and the biostimulation high-frequency signal is output by the biostimulation high-frequency signal output unit 13f, and the high-frequency coil 2a of the probe 2 formed separately from the device main body 1 generates the biostimulation of the signal wave output unit 13.

Therefore, according to the magnetic therapy apparatus of this embodiment, by applying the probe 2 separate from the apparatus main body 1 to the affected area of the living body, the affected area and the affected area are irradiated with the high-frequency alternating magnetic field generated by the high-frequency coil 2a. It can be expected to stimulate peripheral cells and nerves, activate damaged nerves in the affected area, and reduce neuropathy in the affected area through self-repair.

Moreover, according to the magnetic therapy apparatus of this embodiment, the basic high-frequency signal shift section 13b of the signal wave output section 13 of the device main body 1 changes the frequency of the biostimulation high-frequency signal within a range of, for example, 250 MHz±10%. , the QP (quasi peak) value of the harmonic noise is lower than when the frequency of the biostimulation high-frequency signal is constant, and the biostimulation high-frequency signal of high intensity within the EMI standard is applied to the high-frequency coil 2a. can be supplied to generate a high-intensity, high-frequency alternating magnetic field for stimulation of the affected area.

FIG. 7 is a graph showing, as an example, the output signal level of the biostimulation high-frequency signal output unit 13f and the secondary harmonic noise level when the basic high-frequency signal shift unit 13b of the magnetic therapy apparatus of this embodiment shifts. , and FIG. 8 shows the output signal level and the secondary 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 apparatus of this embodiment does not perform the shift operation. It is a graph shown as a comparative example.

As shown in FIG. 7, when the basic high-frequency signal shift section 13b performs the shift operation, the high-frequency biostimulation signal output section 13f outputs a high-frequency biostimulation signal with a frequency of 250 MHz±10%. The level of the signal BHS is about 54 dB in QP value, and the level of the signal (noise) SHS at a frequency of 500 MHz±10% of the second harmonic is 33.8 dB in QP value, according to EN55011:2009/A1:2010 ( CISPR 11: 2009/A1: 2010) International Standard Group 2 Class B-H QP upper limit of 37 dB.

On the other hand, as shown in FIG. 8, when the basic high-frequency signal shifter 13b did not perform the shift operation, which is shown as a comparative example of the present invention, the biostimulation high-frequency signal with a frequency of 250 MHz was output from the biostimulation high-frequency signal output section 13f. The level of the output signal BHS is about 66 dB in QP value, and the level of the second harmonic 500 MHz frequency signal (noise) SHS is about 39 dB in QP value. : 2009/A1: 2010) exceeded the upper limit of QP value 37 dB of the international standard Group 2 Class B-H.

From this result, according to the magnetic therapy apparatus of this embodiment, the basic high-frequency signal shift section 13b of the signal wave output section 13 of the device main body 1 changes the frequency of the biostimulation high-frequency signal within a predetermined range. The QP value of the harmonic noise is lower than when the frequency of the high-frequency stimulation signal is constant, and a high-strength high-frequency biostimulation signal within the EMI standard is supplied to the high-frequency coil to produce a high-strength high-frequency stimulation of the affected area. It was proved that an alternating magnetic field can be generated.

Furthermore, according to the magnetic therapy apparatus of this embodiment, the biostimulation low-frequency signal generation unit 13e of the signal wave output unit 13 included in the apparatus main body 1 is based on the frequency information of the magnetic signal pattern (for example, 1 kHz or more and 3 kHz or less). A low frequency signal for stimulation is generated, the low frequency signal for biostimulation is output by the low frequency signal for biostimulation 13g, and the low frequency coil 2b of the probe 2 is applied to the signal wave output unit 13 for biostimulation. Since the biostimulation low-frequency signal is supplied from the biostimulation low-frequency signal output section 13g connected to the low-frequency signal output section 13g by the signal cable 3, the low-frequency signal for biostimulation causes the low-frequency coil 2b to rotate. The stimulation generated by irradiating the affected area with a low-frequency alternating magnetic field for stimulation of the affected area reaches the brain (sensory area) from the dorsal horn of the spinal cord through sensory nerves (Aβ fibers: tactile sensation), so that the brain develops tactile sensation. It can also be expected to recognize the pleasantness of pain and activate the descending antinociceptive system to bring about analgesic and relaxing effects.

Furthermore, according to the magnetic therapy apparatus of this embodiment, the basic high-frequency signal modulating unit 13c of the signal wave output unit 13 of the apparatus main body 1 converts the basic high-frequency signal into the biostimulation low-frequency signal generated by the signal wave output unit 13. is frequency-modulated to generate a biostimulation high-frequency signal, and the biostimulation high-frequency signal output unit 13f supplies the frequency-modulated biostimulation high-frequency signal to the high-frequency coil 2a of the probe 2. By stimulating the cells and nerves in and around the affected area with the high-frequency alternating magnetic field for stimulating the affected area generated by the high-frequency coil 2a with the high-frequency biostimulation signal frequency-modulated with the frequency signal, the damaged nerves in the affected area are frequency-modulated. It can be expected to be more active than when it is not present, and to reduce neuropathy in the affected area through self-repair.

Furthermore, according to the magnetic therapy apparatus of this embodiment, the signal wave output unit 13 of the apparatus main body 1 also generates and outputs a low-frequency biostimulation signal, and the probe 2 is connected to the signal wave output unit 13 via the signal cable 3. It also has a low-frequency coil 2b which is connected and supplied with a low-frequency signal for biostimulation from the signal wave output unit 13, and the signal wave output unit 13 modulates the frequency of the basic high-frequency signal with the low-frequency signal for biostimulation. Since the high frequency signal for biostimulation is generated and output separately from the low frequency signal for biostimulation, 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 has an analgesic effect. In addition, the high-frequency alternating magnetic field for stimulating the affected area generated by the high-frequency coil 2a by the high-frequency biostimulating high-frequency signal obtained by frequency-modulating the basic high-frequency signal with the low-frequency biostimulating low-frequency signal can further reduce nerve damage in the affected area. I can expect it.

According to the magnetic therapy apparatus of this embodiment, the frequency of the biostimulation low-frequency signal is 1 kHz or more and 3 kHz or less, and the biostimulation low-frequency signal generates 1 kHz or more and 3 kHz or less in the low-frequency coil 2b. Stimulation by a low-frequency alternating magnetic field is particularly likely to reach the brain from the dorsal horn of the spinal cord via sensory nerves, and is expected to bring about a higher analgesic effect, a relaxing effect, and other neuropathy-reducing effects.

Although the above has been described based on the illustrated embodiments, the magnetic therapy apparatus of the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the claims. The high-frequency signal shifter 13b may shift the basic high-frequency signal of 250 MHz within a range of 250 MHz±20%, for example.

Further, for example, the biostimulation low-frequency signal generation unit 13e generates a biostimulation low-frequency signal in a frequency range different from 1 kHz to 3 kHz, for example, a frequency range of 200 Hz to 3 kHz with a center frequency of 1.6 kHz. may

Thus, according to the magnetic therapy apparatus of the present invention, the signal wave output unit of the apparatus main body generates and outputs the first signal wave for biostimulation, and the probe formed separately from the apparatus main body has the first coil is connected to the signal wave output section by a signal cable, supplied with the first signal wave output from the signal wave generating section, and the first signal wave generates the first alternating magnetic field for stimulating the affected area. By applying a probe separate from the main body of the device to the affected part of the living body, the first alternating magnetic field generated by the first coil is applied to the affected part to stimulate the affected part and the cells and nerves around the affected part. It can be expected to reduce neuropathy in the affected area by activating damaged nerves and self-repairing.
