FIG. 1 is a view for explaining the overall configuration of a magnetic field applying apparatus for relieving skin pain caused by low frequency electric stimulation using a strong magnetic field according to an embodiment of the present invention. FIG. 2 is a view for explaining a configuration of a magnetic field applying apparatus for relieving skin pain caused by low frequency electric stimulation using a strong magnetic field according to an embodiment of the present invention. BACKGROUND OF THE
A magnetic field applying device for relieving skin pain caused by low frequency electric stimulation according to the present invention comprises: a low frequency electric stimulation device (10) for allowing a current to flow deeply to muscles for activation of cells; And a magnetic field generator 20 that is phase-locked with the low-frequency electric stimulation device 10 and generates a strong magnetic field to relieve pain caused by electric stimulation.
In a manual muscle contraction method using electrical stimulation, the flow of current does not reach the deep portion of the muscle layer, and in most cases, the current flows to the muscular layer or near the skin layer in most cases.
Therefore, when excessive current is used to obtain sufficient muscle contraction motion, a large amount of current flows to the skin layer, causing pain to the skin.
Therefore, a method of relieving skin pain caused by excessive electrical stimulation includes a method of effectively delivering a minimum current to the muscular side, a method of directing an induction current to a muscular side having a relatively lower resistance than a skin layer, Cooling and the like.
On the other hand, when the low-frequency electrical stimulation and the strong magnetic field are applied in parallel, it is expected that the use of the least current among the methods for relieving pain and the generation of the induced current are expected. In addition, the mental health department has used direct electrical stimulation or electrospun surgery for cell activation for a long time, but magnetic stimulation using a strong repetitive magnetic field is recently used due to side effects due to electrical stimulation.
There is currently a 'repetitive transcranial magnetic stimulation (rTMS)' using a maximum 3T (Tesla) class magnetic field as a noninvasive method using a magnetic field. By using such a strong magnetic field, it is possible to mitigate skin pain caused by manual muscle contraction using electrical stimulation, and at the same time stimulate and activate cells by magnetic fields.
Gauss (GAUSS) or T (Tesla) is used as the unit of the magnetic field. The size of 1 GAUSS is the magnitude of the magnetic field appearing at a distance of 1 cm from the conductor when a current of 5 A flows through the conductor, and 1 T = 10000 GAUSS. The magnitude of the earth's magnetic field is 0.2 ~ 0.7 GAUSS. In the case of MRI, magnetic field of 1.5 ~ 3T is used and TMS currently uses magnetic field of about 3T. In order to continuously generate magnetic field of 1T or more, Materials, shapes and cooling equipment are required.
In the case of the magnetic field generating apparatus according to the embodiment of the present invention, since it coincides with the electric stimulation signal of the low frequency electric stimulation apparatus 10 (FES), it satisfies the turn on time of about 100 us and the repetition operation of several hundred Hz, It is a device that generates a magnetic field.
FIG. 5 is a view for explaining a power source used in the low-frequency electric stimulation apparatus 10 of the magnetic field applying apparatus for relieving skin pain caused by low-frequency electric stimulation using a strong magnetic field according to an embodiment of the present invention.

Although the charge / discharge test was carried out with a large-capacity ultracapacitor with a capacity over 300F through actual testing, it was confirmed that it was difficult to obtain sufficient instantaneous discharge current due to relatively high ESR (Equivalent Serial Resistance) It is confirmed that the ESR can be obtained through the parallel connection.
The control of the IGBT, which is a switching element for supplying power to the
In the case of continuous pulses in which the current direction of the low-frequency electric stimulation apparatus 10 is constantly the same, the same stimulus is accumulated in the muscle, so resistance to stimulation is generated and the motion of the muscle gradually becomes dull.
For this reason, the output current direction of the low frequency electric stimulation apparatus 10 is appropriately switched during operation, so that the direction of the magnetic field supplied from the
