Electrotherapy is a method of treating a disease by directing electric current to the human body and is used for the treatment of musculoskeletal injuries and diseases, nervous system damage and diseases, circulatory diseases, skin diseases, medical diseases and chronic inflammatory diseases.

Electrotherapy can be divided into high frequency therapy and low frequency therapy depending on the frequency of use.

High-frequency therapy generates high-frequency signals and applies them to the affected part of the human body, thereby generating deep heat in the skin of the human body. Thus, there is an effect of alleviating pain through improvement of blood circulation and regeneration of damaged tissue by making cell division active.

On the other hand, the low-frequency therapy generates low-frequency signals to be applied to the affected part of the human body, thereby relieving the pain by contraction and relaxation of the muscles caused by the electric stimulation.

However, in order to apply the conventional radiofrequency therapy and low-frequency therapy to the human body, the radiofrequency treatment apparatuses and the low-frequency treatment apparatuses have to be used separately. This has increased the financial burden on the medical institutions that have to equip each apparatus.

In addition, since the patient has to selectively treat one of the two therapies, there is a limit to the therapeutic effect. In order to perform both of the two therapies, the cost of the treatment and the time required for the treatment are long, There was a problem.

In this regard, Korean Patent Laid-Open No. 2001-0101459 discloses "electrotherapy apparatus and method ".

1 is a view for explaining an external structure of a high-frequency and low-frequency complex treatment apparatus according to the present invention.

Referring to FIG. 1, the high-frequency and low-frequency complex treatment apparatus according to the present invention includes a main body 100 and a handpiece 200.

The main body 100 is a device for applying a high frequency and a low frequency and is connected to a connection line for supplying a high frequency and a low frequency applied to the main body 100 to a handpiece 200 by a predetermined length.

The handpiece 200 may include a handle portion that can be gripped by a hand, and an insertion portion that is drawn out from the handle by a predetermined length and inserted into the skin of the patient.

The main body 100 and the handpiece 200 described and illustrated herein are of a general shape, and the outer structure is not limited thereto and can be freely changed in design.

FIG. 2 is a view for explaining a configuration of a high-frequency and low-frequency complex treatment apparatus according to the present invention, and FIG. 3 is a view for explaining a frequency filter unit employed in the high-frequency and low-

2, the high-frequency and low-frequency complex therapy apparatus 100 according to the present invention mainly includes a high-frequency generating unit 110, a low-frequency generating unit 120, an amplitude modulating unit 130, an FET H- 140, a high frequency transformer 150, and a frequency filter 160.

The high frequency generating unit 110 generates and supplies a high frequency current by an external power source.

In this case, a high frequency refers to a high frequency radio wave or an alternating current, and refers to a frequency higher than an audible frequency (20 Hz to 20 kHz) or a radio wave in a range of 3 to 30 MHz. An alternating current of 100 kHz or more is referred to as a " current. The former often refers to frequencies higher than audible frequencies (20 to 20,000 Hz), and the latter refers to radio waves in the range of 3 to 30 MHz.

High-frequency currents are used in medical fields such as quenching of metals, drying of wood, industrial fields such as high-frequency therapy, as well as wire communication such as return telephones and carrier telegraphs. The high-frequency current used in high-frequency therapy refers to an alternating current of 100,000 Hz or more. When oscillating impulse is very short when a high-frequency current is passed through a human body, ion motion hardly occurs and electrochemical reaction or electricity There is no electrorolytic reaction, and fast vibrational current energy is converted into heat energy in the path. In addition, the pulse duration that can stimulate the normal muscles is about 1 ms, but the pulsating period of the high frequency current is only 0.001 ms, unlike the other current types, it does not stimulate sensory nerve and motor nerve, Can heat certain areas in the body tissue without causing the problem.

The low frequency generator 120 generates and supplies a low frequency current by an external power source.

At this time, low frequency refers to a low frequency wave, which is opposite to high frequency, usually 10kHz or less. The low frequency used in the low frequency therapy in which the low frequency current is used is a device used for treatment of nerves and muscles by applying a low frequency pulse to the living body with a square wave having a width of 0.01 to 1 ms and a frequency of 1 to 500 Hz. Use an anode when calming down pain and a cathode when stimulating paralysis.

The amplitude modulator 130 modulates the amplitude of the supplied high frequency current to generate a high frequency and a low frequency simultaneously. Here, modulation refers to changing an AC signal of a high frequency in accordance with an AC signal of a low frequency. This is the process of including a relatively low audible frequency at a relatively high frequency, called a carrier wave, for transmission of the signal. Carrier wave is the high frequency used for modulation and carries the signal wave of voice. Therefore, amplitude modulation (AM) is an operation of changing the amplitude of a carrier wave according to the intensity of a signal wave. Here, the carrier wave is a sweep wave, and the demodulation is a process of receiving a sweep wave and reproducing a signal wave included in the sweep wave.

Accordingly, the amplitude modulator 130 modulates the amplitude of the high-frequency current so that the characteristics of the low-frequency are superimposed on the high-frequency.

FET (Field Effective Transistor) The H-bridge unit 140 amplifies a high-frequency voltage including characteristics of a low frequency and applies the amplified voltage to the load.

The high frequency transforming unit 150 changes the amplified voltage of the high frequency including the low frequency characteristic according to the rated voltage of the load.

The high-frequency transformer 150 can increase or decrease the voltage input from the outside according to the rated voltage of the load by using an inverter capable of freely modulating a frequency of 200 Hz or more and a frequency of 1 KHz or more.

The frequency filter unit 160 passes only a predetermined frequency component range at a rated voltage and transmits the signal to the handpiece 200 contacting the skin of the patient.

The frequency filter unit 160 passes only a predetermined frequency component range as shown in FIG. 3 (a), and, as shown in FIG. 3 (b), corresponds to a predetermined frequency component range at the rated voltage Frequencies that are not allowed can be filtered.

The handpiece 200 may include a demodulator 210 and an electrode 220.

The demodulator 210 demodulates the waveform modulated by the nonlinearity of the living tissue in the skin into high frequency and low frequency when the skin of the patient contacts with the skin.

At this time, the modulation waveform received by the human body is analyzed by the square modulation equation as follows.

It can be seen that only the input signal is passed through the frequency filter unit 160.

The electrode unit 220 transmits the demodulated high frequency and low frequency to the patient's skin.

Although not shown in the drawing, the handpiece 200 may include an electrode part velocity adjusting part for adjusting the velocity of the electrode part 220, an electrode part movement detecting part for collecting movement information of the electrode part 220, And an electrode position adjuster for adjusting the position of the electrode 220 by feedback.

FIG. 4 is a diagram for explaining the sequence of the high-frequency and low-frequency combined treatment method according to the present invention.

Referring to FIG. 4, the high-frequency and low-frequency complex treatment method according to the present invention uses the above-described high-frequency and low-frequency complex treatment apparatus, and a description thereof will be omitted.

First, a high frequency current is generated and supplied by an external power source (S100).

Next, a low frequency current is generated and supplied by an external power supply (S110).

Next, the amplitude of the supplied high-frequency current is modulated to generate high frequency and low frequency simultaneously (S120). In step S120, the amplitude of the high frequency current is modulated so that the characteristics of the low frequency are superimposed on the high frequency.

Next, a high-frequency voltage including a low-frequency characteristic is amplified and applied to the load (S130).

Next, the amplified voltage of the high frequency including the characteristic of the low frequency is changed according to the rated voltage of the load (S140). In step S140, the inverter can be used to increase or decrease the voltage input from the outside according to the rated voltage of the load.

Then, only the predetermined frequency component range is transmitted from the rated voltage to the handpiece contacting the skin of the patient (S150). In step S150, the high frequency passing through the frequency component range includes low frequency characteristics.

Next, the waveform modulated by the nonlinearity of the living tissue in the skin of the patient is demodulated into high frequency and low frequency (S160).

Finally, the demodulated high frequency and low frequency are transmitted to the patient's skin (S170).

5 is a view for explaining the effect of the high-frequency and low-frequency complex treatment apparatus and method according to the present invention.

Referring to FIG. 5, the conventional combined therapy apparatus has a configuration in which a high-frequency treatment apparatus and a low-frequency treatment apparatus are separately arranged and densely arranged in a single space due to hardware limitations. In this case, since the frequency difference between the high frequency and the low frequency is large, a separate high frequency transformer and a frequency filter have to be used. As a result, the electrodes of the handpiece were separately formed.

However, in the high-frequency and low-frequency complex treatment apparatus according to the present invention, a low-frequency wave is simultaneously generated by high-frequency amplitude modulation in one waveform generator using the amplitude modulation method, thereby minimizing the hardware volume and reducing power consumption. Since a single electrode is used for the handpiece, the efficiency of treatment is improved as compared with the method using each electrode.

As described above, according to the present invention, it is possible to perform the high-frequency treatment and the low-frequency treatment by one treatment using one treatment apparatus, and simultaneously provide the high-frequency treatment effect and the low-frequency treatment effect without each treatment apparatus, It is possible to solve the time problems according to the problem and the procedure time.
