Abstract

The present invention relates to a high frequency therapeutic apparatus for treating multi-joints and, more specifically, to a high frequency therapeutic apparatus which can: maximize therapeutic effects by improving tightness to fit with a curved body part like a multi-joint; and efficiently perform high frequency therapy by generating high frequency corresponding to resonance frequency of a human body part. To achieve this, the high frequency therapeutic apparatus for treating multi-joints comprises: an insulated electrode unit which generates and emits high frequency to a body part through high frequency power supplied with flexibility; and a high frequency controller which controls the high frequency power supplied to the insulated electrode unit. The high frequency controller determines frequency of power supplied in response to the resonance frequency of a human body part. According to the present invention, since the insulated electrode unit with flexibility comes in contact with a curved body part, the generated high frequency is effectively delivered to the human body part. In addition, as power corresponding to the resonance frequency of the human body part can be provided to the insulated electrode unit, the high frequency therapeutic apparatus can minimize power consumption and maximize efficiency. Furthermore, the supplied frequency can be controlled with different resonance frequencies for each body part in real time, thus the high frequency therapeutic apparatus can provide power suitable for each body part. In addition, deep heat can be maximized while minimizing a leakage of high frequency generated in the insulated electrode unit into the outside of the body part by winding a band unit around a cylindrical body part like arms and legs.

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a high-frequency therapeutic apparatus using a feedback circuit and a flexible electrode.

The present invention relates to a multi-joint high-frequency treatment apparatus, and more particularly, to a multi-joint high-frequency treatment apparatus for improving multi-joint high-frequency treatment apparatuses by improving adhesiveness so as to fit a curved body part such as a joint, maximizing a therapeutic effect and generating a high frequency corresponding to a resonance frequency To a high frequency treatment apparatus capable of performing high frequency treatment.

Generally, electrical therapy refers to an electrotherapy that heals a disease by passing current directly through the body. There are three types of electric therapy used for medical use: pseudo-electricity, reactive electricity, and alternating-current electricity. The electric therapy has various functions and uses depending on the frequency of the frequency, the intensity of the electric current,

In recent years, a high frequency treatment apparatus and a low frequency treatment apparatus have been developed and used according to the frequency to be applied. The low-frequency treatment apparatus uses a frequency of several Hz to 1,000 Hz, and the high-frequency treatment apparatus uses a frequency of 10,000 Hz or more to treat a specific region of the human body.

In particular, the high-frequency treatment apparatus applies a high-frequency signal to a lesion portion of a human body to apply heat to the deep region to stimulate sensory nerves and motor nerves, thereby reducing the inconvenience in the human body, A specific region could be heated.

Such a high-frequency treatment apparatus generally comprises a main body for generating a high-frequency current, a therapeutic electrode and an electrode plate, and generates a deep heat in the body through a current between the electrode for treatment and the electrode plate, .

However, in the above-described conventional high frequency treatment apparatus, when the same amount of high-frequency current is applied to the electrode, the electrode having a small diameter has a high current density, thereby providing a cause of image-like danger.

Above all, since the electrode is made of a non-bending metal electrode, the electrode is not firmly adhered to a bending part, for example, a joint part, resulting in a poor wearing feeling and a poor therapeutic effect. For example, high-frequency stimulation to the joints of the body is not properly applied, so that the therapeutic effect is not exhibited.

In addition, in the case of the conventional high frequency treatment apparatus, since it is not possible to detect whether or not the human body is in contact with the human body, there is a risk that the electric current flows in a state where the human body is not in contact with the human body. Furthermore, there is a risk that the user feels uncomfortable with the generated heat or burns because the temperature of the heat generation applied to the human body by the RF treatment apparatus can not be confirmed in real time based on the temperature suitable for the human body.

Furthermore, since the resistance value of each part of the human body is different, it is important to determine the high-frequency current corresponding to the human body part in order to generate the appropriate deep heat. However, since it is difficult to measure the resistance value of the body part changed in real- There is a problem in that the appropriate current value can not be determined in accordance with the body part in the case of the treatment apparatus.

Disclosure of the Invention The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a flexible patch type electrode and a multi-joint type electrode having an insulating pad structure, And an object thereof is to provide a high-frequency treatment apparatus.

It is another object of the present invention to provide a high-frequency treatment apparatus for generating a heat suitable for a patient by measuring in real time whether or not the high-frequency treatment apparatus is in contact with the human body and the heat generated thereby.

It is another object of the present invention to provide a high-frequency treatment apparatus which determines a high-frequency driving current suitable for a part of a human body in which a high-frequency treatment apparatus is used in real time and generates a high-frequency degree at a corresponding site.

It is another object of the present invention to provide a multi-joint high-frequency treatment apparatus having a flexible patch-type electrode and an insulating pad structure capable of enhancing the adhesion to the joints of the joints and stimulating sensory nerves caused by the vibrator.

To this end, the present invention relates to an insulated electrode unit for generating a high frequency with respect to a human body region through high frequency power supplied with flexibility; And a high frequency controller for controlling the high frequency power supplied to the insulating electrode part, wherein the high frequency controller includes a high frequency treatment device for determining a frequency of power supplied to correspond to a resonance frequency of a human body part to provide.

According to the present invention, since the flexible insulating electrode can be closely attached along the bent portion of the human body, the high frequency generated can be efficiently transmitted to the human body.

Further, since the electric power corresponding to the resonance frequency of the human body part can be provided to the insulating electrode part, the maximum deep heat can be generated while minimizing the power consumption rate. Furthermore, since the supply frequency can be controlled in real time according to different resonance frequencies for each part of the human body, it is possible to provide an appropriate power to the body part.

In addition, the bend portion is wound around a cylindrical portion such as an arm and a leg so that the leakage of the high frequency generated from the insulating electrode portion to the outside of the human body can be minimized, and the deep heat can be maximized.

Furthermore, by providing a vibration massage function simultaneously with the generation of deep heat through a high frequency in the human body region through the vibrator, more effective high frequency treatment is provided.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Fig. 1 is a diagram illustrating an example of a high frequency treatment apparatus 1 according to an embodiment of the present invention.

1, the RF treatment apparatus 1 according to an embodiment of the present invention includes a high frequency therapeutic apparatus 1 for giving a high frequency treatment to a specific region of a human body (hereinafter referred to as a "human body region 400"), An insulating electrode unit 100 and a high-frequency controller 200.

The insulation electrode unit 100 according to the present invention includes a flexible cloth electrode unit 103 and a pair of insulation pad units 101 and 1011 and 1013 made of a material for insulating upper and lower surfaces of the cloth electrode unit Respectively.

Here, it is preferable that the cloth electrode unit 103 is made of a conductive material so that commonly known +, - electrodes are applied, and at the same time, a flexible material such as a conductive cloth.

The insulating pad part 101 (1011, 1013) is flexible like the cloth electrode part and has an insulating effect from the cloth electrode part 103 and is made of an insulating material such as rubber, urethane or silicone Can be produced. However, the material is not limited to such a material. The insulation pad unit 101 has a function of directly insisting the human body part and insulating the human body part and the cloth electrode part so that the current flowing in the cloth electrode part 103 does not flow to the human body. The insulating pad portion 101 is provided with a lower surface insulating pad portion 1013 directly contacting the human body and attached to the lower surface of the cloth electrode portion and an upper surface insulating pad portion 1011 attached to the upper surface of the cloth electrode portion .

Hereinafter, the structure of the insulating electrode unit 100 will be described in more detail with reference to an enlarged view of FIG.

1, the insulating electrode unit 100 of the high frequency treatment apparatus 1 according to the first embodiment of the present invention includes a cloth electrode unit 103 made of a conductive cloth so as to have flexibility, And an insulating pad portion 101 made of medical PVC and non-toxic nonconductive rubber so as to be adhered to the upper and lower surfaces of the pad portion 103.

Here, the cloth electrode unit 103 is made of cloth which is a flexible material so as not to be damaged by bending. Such cloth is conductive by the high frequency controller 200 to transmit a high frequency to a human body part. The cloth electrode portion 103 can be manufactured by variously forming the pad, and is very advantageous because it has good bendability and adhesion even when it comes into contact with a human body.

On the other hand, when the insulation pad portion 101 is made of medical PVC and / or non-toxic nonconductive rubber having insulating properties, the cloth electrode portion 103 is insulated from the upper and lower surfaces of the cloth electrode portion 103.

At this time, the rubber compound to be combined with PVC may be natural rubber or synthetic rubber. For example, styrene butadiene rubber (SBR), polychloroprene rubber (CR), acrylonitrile-butadiene rubber (NBR), isoprene-isobutylene rubber (IIR), butadiene rubber butadiene rubber (BR), isoprene rubber (IR), ethylene propylene rubber (EPR), polysulfide rubber, silicone rubber, urethane rubber, A synthetic rubber such as an acrylic rubber may be made of a nonconductive insulating pad portion 101. [

These natural or synthetic rubbers may be prepared in various combinations when combined with PVC. Further, it is needless to say that the insulating pad portion 101 may be made by itself without being combined with PVC in any ratio.

Meanwhile, the upper surface insulation pad portion 1011 attached to the upper surface of the cloth electrode portion 103 according to the present invention preferably has a thickness of 0.3 mm to 0.7 mm. If the thickness is less than 0.3 mm, it is too thin to be easily damaged. If the thickness is more than 0.7 mm, it is difficult to adhere to the joints of the human body due to the low flexibility (flexibility) and adhesion (wearability) It improves adhesion (wearability) and bendability and helps to treat high frequency.

The lower surface insulation pad portion 1013 attached to the lower surface of the cloth electrode portion 103 should be made of a material having a low density because a high frequency wave must pass through it. For example, the upper surface insulating pad portion 1011 may be made of a silicon material because high frequency radio waves need not pass therethrough. However, in the case of the lower surface insulating pad portion 1013, Silicone materials can not be used because the radio wave can not pass through or the through rate is very low. For this reason, it is preferable to use a urethane material for the lower surface insulating pad portion 1013.

FIG. 2 is a view showing a method of connecting the upper and lower surface insulating pad portions 101.

The insulating pad portion 101 is preferably made of urethane. The insulating pad portion 101 is attached to upper and lower surfaces of the electrode portion with the cloth electrode portion 103 as a center. At this time, the edge of the insulating pad portion 101 is formed with a fusion line, The upper surface insulating pad portion and the lower surface insulating pad portion are coupled (fused) to each other through a fusion welding method (hereinafter referred to as a high-frequency thermal welding method). At this time, for bonding between the urethane materials, the hot melt is melted by the heat applied when the strip-shaped hot melt is interposed between the upper surface insulative pad portion and the lower surface insulative pad portion, so that the upper and lower insulating pads of the urethane material are bonded to each other . If such a high-frequency welding and heat-sealing method is not used, the urethane material is not completely coupled to each other, causing the upper surface insulating pad and the lower surface insulating pad to be separated from each other. In the case of using the bonding method shown in FIG. 2, since the conductive cloth electrode portion 103 is located between the strip-shaped hot melts, A portion of the corner should be cut so that the power line 300 can be connected.

The high frequency controller 200 applies the + and - voltages to the insulation electrode unit 100 to apply the power to the insulation electrode unit 100 so that high frequency is generated in the cloth electrode unit 103, .

The high frequency controller 200 according to the present invention determines the power value corresponding to the resonance frequency of the human body part and supplies the power value to the insulating electrode part 100, And a resonance frequency determination unit for generating a maximum deep heat with respect to the region. Furthermore, as will be described later, when the resonance frequency determining unit is used, it is possible to determine whether or not the insulating pad is attached to the human body.

Hereinafter, the resonance frequency determining unit will be described with reference to FIGS.

When the insulation electrode unit 100 of the high frequency controller 200 is attached to the human body, a change in the current or voltage value flowing through the insulation electrode unit 100 occurs due to the load value at the human body. 3, the high frequency controller includes a resonance frequency determiner (not shown) that changes the frequency of the high frequency supplied to the insulation electrode unit 100 based on the change value of the current or voltage through the feedback circuit 215 210). The target value of the changed frequency is the resonance frequency value of the human body part.

Hereinafter, the resonance frequency determination unit 210 will be described in more detail with reference to FIG.

The resonance frequency determining unit 210 is supplied with the rectified current through the rectifying and filtering circuit 220. Then, the resonance frequency determining unit 210 amplifies the magnitude (voltage) of the current using the field effect transistor (FET) 211. Thereafter, the voltage is increased through the power transformer 212, and the high-frequency power is supplied to the insulating electrode unit 100 through the resonance and filtering circuit 213.

As described above, since it is impossible to directly measure the resonance frequency of the human body part, the present invention is applicable to the resonance frequency of the human body part on the side of the high frequency controller 200 through the current or voltage change value on the insulating electrode part 100 side To determine the frequency. For this, the resonance frequency determining unit 210 includes a feedback circuit 230 that feeds back a current or voltage change value on the insulating electrode unit 100 side.

At this time, the resonance frequency determining unit 210 determines, based on the current or voltage change value fed back through the feedback circuit 230, the human body having the maximum current or voltage value in the insulating electrode unit 100, The frequency corresponding to the resonance frequency of the portion is determined.

 The resonance frequency determining unit 210 sequentially supplies power having two or more frequencies having different values within a predetermined range to the insulating electrode unit, thereby determining a frequency corresponding to the resonance frequency of the human body part. For example, the resonance frequency determining unit 210 sequentially supplies power of a plurality of frequencies having predetermined intervals (for example, 5 to 50 kHz) within the range of 100 kHz to 1 MHz to the insulating electrode unit 100 The frequency at which the maximum current value or the voltage value is determined as the frequency corresponding to the resonance frequency of the human body part.

More specifically, the middle of the inductors L0 and L of the resonant and filtering circuit 213 is insulated (indicated by insulation in Fig. 4), and the left and right values of the insulated inductor are L0 and L, respectively. Hereinafter, the left side of the insulated reference is referred to as the primary side, and the right side of the insulated reference is referred to as the secondary side. At this time, the human body part is in non-contact with the insulating electrode part 100 (more precisely, the cloth electrode part 103 generating high frequency is not in contact with the human body part 400) , But the secondary side total impedance can be bundled into one by the resistance value R of the human body portion (secondary side impedance Z0 in Fig. 4). That is, when the insulating electrode unit 100 is attached to the human body part, the resonance in the secondary side and the inherent impedance Z0 of the inductor value L, the capacitor value C and the human body resistance R of the filtering circuit 213 ) Is determined. When the secondary side impedance Z0 is resonant with the high frequency frequency value supplied from the high frequency controller 200, a maximum current or a maximum voltage is generated. Therefore, the frequency of the high frequency is changed in the feedback circuit 215, And determines the resonance frequency corresponding to the impedance Z0.

As a method of determining the resonance frequency, the power of a plurality of frequencies having a predetermined interval (for example, 5 to 50 kHz) within the range of 100 kHz to 1 MHz is sequentially supplied to the insulating electrode unit 100 The frequency at which the maximum current value or the voltage value is determined as the frequency corresponding to the resonance frequency of the human body part. The feedback circuit 215 and the CPU receive feedback based on the impedance value of the secondary side and change (control) the frequency period (duty cycle) by using the oscillator OSC and the pulse width modulator PWM, Determine the resonant frequency at which the voltage value can occur.

Since the insulating electrode unit 100 is attached to the human body part at the same time and is instantaneously, periodically, and automatically processed, the resonance frequency determination process provides an appropriate frequency (resonance frequency) to the target human body part, So that the maximum efficiency can be achieved.

In addition, in order to measure heat acting on the human body part, the high frequency treatment apparatus according to the present invention may further include a temperature measuring unit (not shown). The temperature measuring unit measures the human skin heat generated by the deep heat acting on the human body part by being positioned between the cloth conductive part 103 and the lower surface insulating pad part 1013 to determine whether the human body is damaged due to excessive heat It can be judged. The temperature measuring unit may be connected to the high frequency controller 200 to perform an operation of stopping the generation of the high frequency in the high frequency controller when excessive heat (heat of a predetermined threshold value or more) is generated in the human body.

Further, when the resonance frequency determination unit 210 of the high frequency controller according to the present invention is applied, the state of the human body load can be confirmed by determining whether the human body load is applied when the insulating electrode unit 100 is attached to the human body area. That is, if the current is not applied to the human body and the voltage is changed to the minimum value, the current or voltage change due to the load change when the human body touches the body is different from the basic value. And at this time, it is possible to supply the high-frequency electric power. Therefore, the high frequency controller 200 can determine whether the insulating electrode unit 100 is attached to the human body in real time and securely apply the high frequency.

Hereinafter, referring to Figs. 5 to 7, an insulating electrode portion attached to a human body through a band portion will be described.

According to another embodiment of the present invention shown in FIG. 5, the high frequency treatment apparatus further includes a band portion 500 made of a cloth material and stretched in the longitudinal direction. The band portion has a length enough to be wound around an arm or a leg portion of the human body. In a more preferred embodiment, both ends of the band portion 500 may have a fixing portion (e.g., a Velcro, a hook, a button, etc.) so that the band portion 500 is wound after being wound around an arm or leg portion of the human body. At least two insulating electrode parts 100 are attached to the inner surface of the band part 500 in a detachable manner with a predetermined gap therebetween. In the case of the method of attaching the insulating electrode unit 100, a detachable fixing method such as a Velcro type may be used between the upper surface of the insulating electrode unit 100 and the inner surface of the band unit 500 so as to be easily removable. But any method capable of detachment can be used.

FIG. 6 shows an example in which a band portion having the insulating electrode portion is wound around an arm of a human body portion.

7 is a view showing a state in which two insulating electrode parts attached to a band part are wound on an arm or a leg part so as to be in contact with a human body while facing the lower side.

Generally, in the case of generating deep heat of a human body region through a high frequency wave, a considerable number of high frequency components can not permeate the inside of the human body and flow out to the outside of the human body. Therefore, as shown in FIG. 7, When the lower surfaces are arranged to face each other, the efficiency can be maximized.

8 is a cross-sectional view illustrating an insulating electrode unit 100 having vibration characteristics according to an embodiment of the present invention.

The insulating electrode part 100 according to the present invention includes a vibrator part 104 disposed between the upper surface of the cloth electrode part 103 and the upper surface insulating pad part 1011 to generate vibration .

At this time, the vibrator portion 104 formed on the upper surface of the cloth electrode portion 103 and formed below the insulating pad portion 1011 is formed on the upper surface of the printed circuit board 104a and the printed circuit board 104a A vibration element 104b for generating a vibration signal, a motor 104c for supplying power to the vibrator 104d in accordance with the vibration signal, and a vibrator 104d for generating vibration by the motor 104c.

When the insulating electrode unit 100 is closely attached to the articulation part of the human body, the vibrator unit 104 generates vibration and stimulates the human body part 400. Therefore, the effect of the high-frequency treatment on the sensory nerve in the human body region can be further enhanced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the exemplary embodiments or constructions. You can understand that you can do it. For example, the stock consolidation system described above is only an example, and it goes without saying that the present invention is also applied to a transmission / reception module of all transmission / reception systems that exchange data. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
