In the magnetic therapy apparatus of this embodiment, the basic high-frequency signal generation section, the basic high-frequency signal shift section, and the basic high-frequency signal frequency modulation section of the signal wave output section of the device main body 1 generate the biostimulation high-frequency signal.

Then, a biostimulation high-frequency signal output from the biostimulation high-frequency signal output unit, for example, having a center frequency of 250 MHz is supplied, and the biostimulation high-frequency signal generates a high-frequency alternating magnetic field for stimulation of the affected area.

Therefore, according to the magnetic therapy apparatus of this embodiment, by applying the probe 11, which is separate from the apparatus main body 1, to the affected area of the living body, the affected area is irradiated with the high-frequency alternating magnetic field generated by the high-frequency output coil 15. This stimulation activates, for example, damaged sensory cells in the affected area, induces neurotrophic factors, and can be expected to alleviate neuropathy in the affected area. Since it has a strong effect of activating the sensory cells and inducing neurotrophic factors, it can be expected to increase the effect of alleviating neuropathy in the affected area.

Furthermore, according to the magnetic therapy apparatus of this embodiment, the biostimulation low-frequency signal generation unit of the signal wave output unit of the device main body 1 uses the frequency information (for example, 1 KHz or more and 3 KHz or less) of the magnetic signal pattern for biostimulation. A low-frequency signal is generated, the biostimulation low-frequency signal output section outputs the biostimulation low-frequency signal, and the low-frequency output coil 17 of the probe 11 outputs the biostimulation low-frequency signal of the signal wave output section. Since the low-frequency signal for biostimulation is supplied from the low-frequency signal output part for biostimulation which is connected to the signal output part by the signal cable 21, the low-frequency signal for biostimulation is generated by the low-frequency output coil 17. The stimulation given 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 the sensory nerves (Aβ fibers: tactile sensation), so that the brain is stimulated by tactile sensation.

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 output coil 17 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 output coil 15 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 further reduces nerve damage in the affected area. can be expected.

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 Stimulation by a low-frequency alternating magnetic field of 3 kHz or less is particularly easy to conduct from the dorsal horn of the spinal cord to the brain through sensory nerves. .
