According to some embodiments of the present disclosure, the pulse current output unit 150 may transmit a pulse current to at least one of the first coil 112 and the second coil 122. Meanwhile, the controller 180 may control the pulsed current output unit 150 to transmit a pulsed current alternately to each of the first coil 112 and the second coil 122.

Specifically, when transmitting a pulse current to the first coil 112 during the first stimulation time 11, the controller 180 controls the pulse current output unit 150 to not transmit the pulse current to the second coil 122. Can be controlled. In addition, the controller 180 controls the pulse current output unit 150 so as not to transmit the pulse current to the first coil 112 when transmitting the pulse current to the second coil 122 during the second stimulation time 21 can do. Accordingly, the controller 180 may prevent heat generation of the first coil 112 and the second coil 122, respectively, thereby preventing damage to the coil due to heat generation.

In addition, the controller 180 may control the pulse current output unit 150 so as not to transmit the pulse current to the first coil 112 during the first pause time 12 after the first stimulation time 11 has elapsed. have. In addition, the controller 180 can control the pulse current output unit 150 so as not to transmit the pulse current to the second coil 122 during the second pause time 22 after the second stimulation time 21 has elapsed. have. Here, the second stimulation time 21 may exist within the first pause time 12, and the first stimulation time 11 may exist within the second pause time 22. In addition, the length of the first pause time 12 is longer than the length of the first stimulation time 11 and the length of the second stimulation time 21, and may correspond to the length of the second pause time 22.

According to some embodiments of the present disclosure, the controller 180 turns on the first switch 111 connected between the pulse current output unit 150 and the first coil 112 during the first stimulation time 11, The first switch 111 may be turned off during the first pause time 12. In addition, the controller 180 turns on the second switch 121 connected between the pulse current output unit 150 and the second coil 122 during the second stimulation time 21, and a second pause time 22 During this time, the second switch 121 may be turned off.

For example, the controller 180 turns on the first switch 111 for 3 seconds, which is the first stimulation time 11, and after 3 seconds, which is the first stimulation time 11, the first pause time ( The first switch 111 may be turned off for 6 seconds, which is 12). In connection with this, the controller 180 turns on the second switch 121 for 3 seconds, which is the second stimulation time 21 included in the first pause time 12, 6 seconds, and the second stimulation time After 3 seconds of (21) elapses, the second switch 121 may be turned off for 6 seconds, which is the second pause time 22.

Meanwhile, the first coil 112, which received the pulse current from the pulse current output unit 150 during the first stimulation time 11, applies the first pulsed magnetic field 410 having a first frequency value to the first stimulation time ( 11) Can be created during. In addition, the second coil 122, which received the pulse current from the pulse current output unit 150 during the second stimulation time 21, has a second pulse magnetic field 420 having a second frequency value corresponding to the first frequency value. ) May be generated during the second stimulation time 21. However, the present invention is not limited thereto, and the first frequency value and the second frequency value may be different depending on the thickness, number of windings, and material of each of the first and second coils 112 and 122 described above.

The description of the presented embodiments is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be apparent to those of ordinary skill in the art, and general principles defined herein may be applied to other embodiments without departing from the scope of the present disclosure. Thus, the present disclosure is not limited to the embodiments presented herein, but is to be interpreted in the widest scope consistent with the principles and novel features presented herein.
