Description

[Technical Field]

[0001] The present invention relates to an electric potential therapy device, and more particularly to a technique for controlling the electric potential of an electric potential therapy device. [Background technology]

[0002] An electric potential therapy device is a device that generates an electric field around the human body and stimulates the human body with that field to achieve a therapeutic effect.

[0003] For this reason, the electric potential therapy device applies high voltage to the insulated human body through pads, but since the floor and walls of the room surrounding the human body are close to the earth, which has a potential of 0V, an electric field is formed between the high voltage and the earth, which is the floor or wall.

[0004] Conventional electric potential therapy devices generate an electric field in only one direction by fixing the phase difference between the pads, which limits the ability to provide appropriate stimulation to each part of the body and achieve therapeutic effects.

[0005] In addition, since different voltages are used for different treatment areas, the amount of output current also changes with each change in voltage, which causes the electric shock sensation felt by the user to change, leading to psychological anxiety for the user.

[0006] The inventors of the present invention have been researching and working to solve these problems with conventional electric potential therapy devices. After much effort, they have been able to complete the present invention, which is an electric potential therapy device that can deliver therapeutic effects to various parts of the body and prevent electric shocks by adjusting the phase and electric potential of each pad of the electric potential therapy device. Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention aims to prevent electric shocks while delivering therapeutic effects to various parts of the body by setting different phases and voltages for each pad in an electric potential treatment device including multiple pads.

[0008] On the other hand, other objects of the present invention not explicitly stated will be considered within the scope that can be easily inferred from the detailed description below and the effects thereof. [Means for solving the problem]

[0009] The electric potential therapy device of the present invention includes a power supply input unit to which an AC power source is input; a first transformer unit that converts the input voltage of the power supply input unit into a high voltage; a second transformer unit that converts the input voltage of the power supply input unit into a voltage that is the same as the output voltage of the first transformer unit but has an opposite phase to the output voltage of the first transformer unit; a third transformer unit that converts the input voltage of the power supply input unit into a voltage that is lower than the output voltage of the first transformer unit; a plurality of pads connected to the first, second or third transformer unit; and a switch unit that controls the connection between the first, second or third transformer unit and the plurality of pads.

[0010] The electric potential treatment device further includes a control unit including one or more processors and a memory, and the control unit controls the connection state of the switch unit according to a user's input.

[0011] The switch unit is configured so that one of the pads is connected to the output tap of the first transformer unit and one of the remaining pads is connected to the output pad of the second transformer unit.

[0012] Of the remaining pads, excluding the pads connected to the first and second transformers, only the pads that come into contact with the part of the user that needs treatment are connected to the output tap of the third transformer.

[0013] The remaining pads except for the pads connected to the first transformer and the second transformer are all connected to the output tap of the third transformer. [Effects of the Invention]

[0014] According to the present invention, by adjusting the potential and phase of the pads of the electric potential treatment device, it is possible to maximize the therapeutic effect on various parts of the user's body, and by reversing the voltage and phase of unused pads from the main voltage, it is possible to prevent electric shocks.

[0015] On the other hand, it is noted that even if an effect is not explicitly mentioned here, the effects and provisional effects described in the following specification that are expected by the technical features of the present invention are treated as the same as those described in the specification of the present invention.

For example, a "first component" may be referred to as a "second component," and similarly, a "second component" may be referred to as a "first component" without departing from the scope of the present invention.

[0019] Hereinafter, the configurations of the present invention and the effects resulting from the configurations thereof will be described in detail with reference to the drawings, which illustrate various embodiments of the present invention.

[0020] FIG. 1 is a structural diagram of an electric potential treatment device for controlling the flow of electric potential according to a preferred embodiment of the present invention.

[0021] An electric potential therapy device 100 according to the present invention includes a power supply input section 110, transformer sections 120-124, output resistors 130-134, switch sections 141-145, 151-155, and pad sections 160-165.

[0022] The power input unit 110 receives AC power input and transmits it to the transformer unit.

[0023] The transformers 120, 122, and 124 respectively convert the voltage and phase of the AC power supply for potential treatment.

[0024] The first transformer 120 converts the AC power from the power input unit 110 into a high voltage, which may be 9000 volts (9 kV) or higher.

[0025] The second transformer 122 also converts the AC power from the power input unit 110 into a high voltage. The voltage is the same as that of the first transformer 120, but the phase is opposite to that of the first transformer 120.

[0026] The first transformer 120 and the second transformer 122 are high voltage, and by using the same voltage but opposite phases, the potential of the user who is the patient can be made close to zero, thereby preventing electric shock.

[0027] The third transformer 124 converts the AC power from the power input unit 110 into a low voltage. The low voltage is a voltage lower than that of the first transformer 120 and the second transformer 122, and may be 450 volts (450V) or less.

[0028] The third transformer 124 has a phase opposite to that of the output voltage of the first transformer 120 and a lower voltage, thereby allowing a minute current to flow between the pad connected to the first transformer 120 and the pad connected to the third transformer 124, thereby achieving a therapeutic effect on the desired area.

[0029] The output resistors 130, 132, and 134 adjust the output current transmitted to the pads 160-165.

[0030] The switch section is made up of voltage selection switches 141 to 145 and connection switches 151 to 155.

[0031] The voltage selection switches 141 to 145 are used to select which transformer each pad is connected to.

[0032] The user can connect the pads that are not being used for treatment to the second transformer 122 to generate a high voltage of opposite phase to that of the first transformer 120, thereby preventing electric shock.

[0033] The treatment pads are connected to the third transformer 124, which generates a low voltage of opposite phase to the output of the first transformer 120, allowing current to flow and providing a therapeutic effect.

[0034] The connection switches 151 to 155 allow each pad to be connected to the transformer. By disconnecting unused pads, unwanted current flow and electric shock can be prevented.

[0035] The pad section 160 to 165 includes a fixed pad 160 of a high voltage plus (+) phase and variable pads 161 to 165 selectively connected to a high voltage minus (-) phase or a low voltage minus phase.

[0036] The fixing pad 160 is generally placed on the user's head to form an electric field around the user's body.

[0037] The variable pads 161 to 165 are located on the areas to be treated by generating an electric field, such as the buttocks, back, arms, and legs. The variable pads on the areas requiring treatment are connected to the third transformer 124, and the unused variable pads are connected to the second transformer 122 to prevent electric shock.

[0038] For example, the first variable pad 161 can be located on the buttocks, the second variable pad 162 on the back, the third variable pad 163 on the left arm, the fourth variable pad 164 on the right arm, and the fifth variable pad 165 on the feet.

[0039] If it is desired to deliver a therapeutic effect only to the back, the second variable pad 162 located on the back must be connected to the third transformer 124. Therefore, the second voltage selection switch 142 must be connected to the third transformer 124, and the second connection switch 152 must be in an on state.

[0040] To prevent the user from receiving an electric shock, one of the remaining variable pads that is not being used must be connected to the second transformer 122, which has a high voltage with an opposite phase to the output of the first transformer 120. Therefore, the first variable pad 161 located on a part of the body other than the back, for example, the buttocks, can be connected to the second transformer 122. For this purpose, the first voltage selection switch 141 must be connected to the second transformer 122, and the first connection switch 151 must be in an on state.

[0041] The remaining unused third, fourth and fifth variable pads 163, 164 and 165 do not need to be connected to the power supply, so the third, fourth and fifth connection switches 153, 154 and 155 are maintained in the OFF state.

[0042] If it is desired to deliver a therapeutic effect to multiple sites, multiple variable pads can be connected to the therapeutic low voltage.

[0043] For example, if one wishes to receive treatment on both the arms and legs, the corresponding variable pads, the third, fourth, and fifth variable pads 163, 164, and 165, must all be connected to the low-voltage transformer, the third transformer 124. Therefore, the third, fourth, and fifth voltage selection switches 143, 144, and 145 must be connected to the third transformer 124, and the third, fourth, and fifth connection switches 153, 154, and 155 must also be connected to the on state.

[0044] One of the first and second variable pads 161, 162, which is not used for treatment, must be connected to the second transformer unit 122, which has the opposite phase of the high voltage, to prevent electric shock. Therefore, the first or second voltage selection switch 141, 142 may be connected to the second transformer unit 122, and the selected switch of the first or second connection switch 151, 152 may be turned on.

[0045] FIG. 2 is a structural diagram of an electric potential treatment device for controlling the flow of electric potential according to another preferred embodiment of the present invention.

[0046] The electric potential therapy device 200 according to another embodiment of the present invention may further include a control unit 270 for controlling the switch. The other components may be configured in the same manner as in the example of FIG.

[0047] The control unit 270 controls the switches according to the user's settings and may include one or more processors and memories. The processor can execute programs and commands for controlling the switches, and the memory can store commands and necessary data for operating the processor.

[0048] The control unit 270 controls the voltage selection switches 241 to 245 as required, and controls the on / off of the connection switches 251 to 255.

[0049] For this purpose, the switch unit may use switching elements such as a field effect transistor (FET), an insulated gate bipolar transistor (IGBT), etc. The control unit 270 controls the switching on / off of such switching elements.

[0050] The control unit 270 controls the connection of the variable pads 261 to 265 according to the treatment area selected by the user.

[0051] For example, the first variable pad 261 can be located on the buttocks, the second variable pad 262 on the back, the third variable pad 263 on the left arm, the fourth variable pad 264 on the right arm, and the fifth variable pad 265 on the feet.

[0052] If the user selects the left arm and the right arm as the treatment area, the control unit 270 controls the switches so that the third variable pad 263 and the fourth variable pad 264 are connected to the third transformer 224. Therefore, the control unit 270 connects the third and fourth voltage selection switches 243 and 244 to the third transformer 224 and controls the third and fourth connection switches 253 and 254 to the on state.

[0053] The control unit 270 can connect one of the remaining pads not used for potential treatment to the second transformer unit 222 as an electric shock prevention pad. The first, second, and fifth variable pads 261, 262, and 265, excluding those for the left and right arms, are not used for treatment and are therefore used for electric shock prevention. For example, if the fifth variable pad 265 is used for electric shock prevention, the control unit 270 can prevent electric shock by connecting the fifth voltage selection switch 245 to the second transformer unit 222 and controlling the fifth connection switch 255 to an on state.

[0054] According to the electric potential therapy device of the present invention, by adjusting the voltage and phase of the pads used for electric potential therapy, it is possible to simultaneously deliver therapeutic effects to various parts of the body as desired by the user, and it is also possible to prevent electric shocks by applying high voltage of the opposite phase to unused pads.

[0055] The scope of protection of the present invention is not limited to the description and expression of the embodiments explicitly described above, and it should be reiterated that the scope of protection of the present invention should not be limited by obvious modifications or substitutions in the technical field to which the present invention belongs.
