Description

Series-Parallel 2-Channel High-Frequency Electrical Therapy Device

The present invention relates to a high-frequency electrical treatment device for therapeutic or cosmetic purposes. The present invention is particularly applicable to the field of electrical treatment for diathermy or conduction therapy.

Electrotherapy is a safe, non-invasive technique that uses electricity for therapeutic purposes. It has been shown to be effective in relieving pain, strengthening muscle fibers, and accelerating tissue healing. Three main frequency groups are used in electrotherapy: low frequency (1 Hz-150 Hz) for superficial nerve stimulation, medium frequency (1 kHz-1 kHz) for deep nerve stimulation, and high frequency (100 kHz-1.2 MHz) for selective superficial or deep diathermy and promoting healing. Low frequency (LF) and medium frequency (MF) are commonly referred to as electrical stimulation, while high frequency (HF) is referred to as radiofrequency. These various types of electrotherapeutic currents circulate between two conductive elements, or plates, that contact the skin and act as electrodes. Thus, therapists can utilize a variety of currents depending on their specific needs.

Diathermy, a type of physical therapy that has been used for many years, is categorized into two types: superficial hyperthermia and deep hyperthermia. Deep hyperthermia methods include longwave and shortwave diathermy, ultrasound, and contact radiofrequency. Contact radiofrequency, also known as high-frequency current, operates at frequencies between 100 kHz and 1.2 MHz. This type of deep hyperthermia is called diathermy. Diathermy heats the damaged tissue between two electrodes in contact with the tissue, causing an electric current to circulate.

As specified in Spanish patent ES 287964, a diathermy device utilizing current conduction comprises an active electrode and a ground electrode. Due to the inherent impedance of the tissue, the current circulates within the tissue, increasing its temperature through the Joule effect. This increases the degree of heating, which is correlated with the intensity of the current. The thermal conductivity of the tissue is enhanced by the high-frequency current. Higher current voltages increase the thermal conductivity of the tissue, accelerating recovery. Multiple electrodes, connected to a single high-frequency voltage generator, simultaneously promote diathermy and tissue recovery during treatment. These two effects occur together and are not separated.

U.S. Patent No. 5,773,173 discloses an interferometric stimulation device for electrotherapy. The device comprises two generators, each generating an output signal with a specific frequency within the device. The output signal passes through another element before passing through a mixer, which is configured to select the output signal via a selector switch that selects between bipolar and quadrupole treatment modes. The device provides a single, synthesized low-frequency signal to the electrode pairs.

U.S. Patent No. 2010/0152817 discloses a network simulator for electrical nerve stimulation using serial/parallel electrode pairs. The simulator continuously generates electrical stimulation and transmits signals sequentially to the serial electrode pairs within a cycle. Each electrode pair receives the corresponding signal in parallel, rather than simultaneously, so the signals do not start and end simultaneously. By applying various electrical stimulations, the simulator can generate simulated stimulations with higher amplitudes or longer durations.

U.S. Patent No. 2003/0181960 discloses a device that generates a therapeutic signal from an electrode using a first electrical signal and a second electrical signal, which is then absorbed by a ground electrode. The device is a low-frequency device and does not offer a wide range of prescribed treatments.

Therefore, patients need safer and more effective treatment solutions, and therapists need simpler and more optimized treatment solutions.

Other features and advantages of the present invention will be discussed with reference to the following description and drawings, and other advantages may also be included.

The present invention is an electrical therapy device that provides diathermy or conduction therapy to a user's body.

In one embodiment, the electrotherapy device of the present invention can provide diathermy treatment or conduction treatment, or can provide treatment by linking diathermy treatment with conduction treatment.

In one embodiment, the electrotherapy device of the present invention can perform different treatments by serializing or parallelizing the generators.

The electrical treatment device of the present invention includes a plurality of electrodes (2-3), and the number of electrodes is referred to as N (N=2 or 3). The number of electrodes may be 2 or 3, or an even or odd number.

The electrotherapy device of the present invention comprises two sinusoidal voltage generators (210, 220). Preferably, the number of sinusoidal voltage generators (210, 220) is determined according to the number of electrodes, particularly the number of active electrodes (212, 222). If the number of electrodes is even, the number of sinusoidal voltage generators is determined accordingly.

The electrotherapy device of the present invention comprises two channels, each channel originating from a voltage generator (210, 220). Active electrodes (212, 222) deliver current to the body of the user (10). Preferably, the active electrodes (212, 222) are each connected to a different channel. The active electrodes (212, 222) are each connected to a voltage generator.

The electrical treatment device of the present invention may be configured to include a ground electrode (240) or a neutral electrode, wherein the neutral electrode refers to an electrode that receives an electric current transmitted from an active electrode (212, 222) and passed through a body part of a user (10). The ground electrode (240) closes an electric circuit of the body of the user (10) and forms a ground. The electrode may preferably be fixed, but may also be flexible depending on the type of treatment. Here, fixed means that the ground electrode does not move during treatment, and in this case, the electrode can be fixed to the body of the user through a retaining device. Flexible means that the electrode can move during treatment.

Electrodes (212, 222, 240) may be provided for application to the body of the user (10). Preferably, the electrodes (212, 222, 240) are in contact with the body of the user (10).

The active electrodes (212, 222) may be capacitive, resistive, or multipolar. Multipolar means that the active electrodes (212, 222) have both capacitive and resistive electrodes.

The active electrodes (212, 222) may be fixed or flexible depending on the treatment.

The electrotherapy device of the present invention includes a control device that can alternately adopt the first and second configurations. The control device is a microcontroller, a microprocessor, a CPLD (Complex Programmable Logic Device), an FPGA (Field Programmable Gate Array), or an analog circuit.

According to the first configuration, the electrotherapy device of the present invention includes N electrodes (N=2), two of which are active electrodes (212, 222) and do not include a ground electrode (240). Each active electrode is connected to a voltage generator (210, 220) connected in parallel. This configuration is illustrated in FIGS. 1 and 2.

According to the second configuration, the electrotherapy device of the present invention comprises N electrodes (N=3), which are active electrodes (212, 222) and a ground electrode (240). The active electrodes (212, 222) are respectively connected to voltage generators (210, 220) arranged in parallel, and the ground electrode (240) is connected to the intersection between the voltage generators. This configuration is illustrated in FIGS. 3, 4, and 5.

According to a preferred embodiment, the voltage generators (210, 220) can be separated, and galvanic separation is performed at this time. According to the embodiment shown in the drawing, a transformer (211, 221) is arranged at the output of each voltage generator (210, 220). By separating the generators, the user can be separated from the electrical circuit of the electrotherapy device of the present invention, thereby increasing safety.

The transformer (211, 222) is provided with a phase shift or dephase shift in the opposite direction as needed to the phase shift or dephase shift of the output signal of the voltage generator (210, 220).

According to the present invention, the use of a ground electrode (240) within the device may be optional. The ground electrode (240) prevents or reduces the occurrence of a circulating origin current between the two active electrodes (212, 222).

Each of the active electrodes (212, 222) is connected to a sinusoidal voltage generator (210, 220) using a separate channel. Preferably, the electrotherapy device of the present invention does not include a switch for transmitting the first signal of the voltage generator (210) or the second signal of the second voltage generator (210) to the active electrodes, and does not include a mixer unit for combining the first generator first signal and the second generator secondary signal.

The signal generated by each generator is applied to one active electrode.

The device of the present invention is provided to generate different potentials at each of the electrodes (212, 222) for current flow between the two closest electrodes among the electrodes (212, 222, 240).

According to the present invention, the active electrode (212, 222) is connected or not connected to the body ground electrode (240) of the user (10) depending on the neutral point or common point configuration.

The device execution step of the first configuration generates a line current (110) between the active electrodes (212, 222), and the second configuration generates a simple current (120, 121) between the active electrodes (212, 222) and a ground electrode (240) attached to the body of the user (10).

According to a preferred embodiment, the electrotherapy device of the present invention can be used for electrotherapy, particularly diathermy. Accordingly, each of the voltage generators (210, 220) is configured to generate high voltage. The high-frequency voltage preferably has a value between 100 kHz and 10 MHz.

The electrotherapy device of the present invention may include a measuring unit (213, 223) for each of the voltage generators (210, 220). The measuring units (213, 223) are provided to measure output signal parameters of the separated generators (210, 220). The measuring units (213, 223) are provided to transmit control data to the control module (214, 224).

The control module (214, 224) controls, for example, the frequency of the current and the phase shift of the voltage generator. For example, the control module (214, 224) is a microcontroller, a microprocessor, a CPLD (Complex Programmable Logic Device), an FPGA (Field Programmable Gate Array), or an analog circuit.

The electrical treatment device of the present invention may include a synchronization unit (230) arranged for the purpose of controlling voltage generators (210, 220). The synchronization unit (230) is arranged at the synchronization introduction part of each of the voltage generators (210, 220) and is provided for synchronization or desynchronization of transmission signals. Here, synchronization means that at least one of the pulse, frequency, and period of the transmission signal is the same. For example, the synchronization unit (230) generates a synchronization signal for each voltage generator to control synchronization or desynchronization of the signal. As shown in FIGS. 4 and 5, during synchronization of the two voltage generators (210, 220), the current circulates between each of the active electrodes (212, 222) and the neutral ground electrode (240), but during desynchronization of the voltage generators (210, 220), the current also circulates between the active electrodes (212, 222), and in the latter case, the current is derived current (110). The synchronization unit (230) can generate and maintain a current derived between two active electrodes by controlling the synchronization or desynchronization of the signal.

According to one aspect of the present invention, the voltage generators (210, 220) of the electrotherapy device of the present invention are independent and can adjust the output signal according to the measured impedance. The electrotherapy device of the present invention may be equipped with a multi-output device, meaning that it may include two active electrodes each connected to two voltage generators that generate different output signals.

Preferably, the signal transmitted by each of the voltage generators (210, 220) is a sine wave. Preferably, V = Vamp × sin(wt + Φ), where Vamp = amplitude of the sine wave signal, w = angular frequency, and Φ: phase angle.

According to another aspect of the present invention, the electrotherapy device of the present invention may be provided so as to enable phasing or dephasing of the signals of each of the voltage generators (210, 220). Accordingly, the output voltage varies depending on the occurrence of a wavelength phase difference. When the signals of the voltage generators (210, 220) are in a phased state, the voltage between the active electrodes (212, 222) is twice the output voltage Vout (V110 = 2 × Vout) (Vout: voltage generator output voltage). When the signals of the voltage generators (210, 220) are dephased by 180°, the output voltage is null, and Vamp = 0V (Vamp: amplitude of the output sinusoidal signal).

A first configuration of a first embodiment of the electrotherapeutic device of the present invention is illustrated in Fig. 1.

According to the first configuration of the first embodiment of the present invention, N=2, and active electrodes (212, 222) are connected to each of the voltage generators (210, 220). In the first configuration, the electrotherapy device of the present invention does not include a ground electrode. In this configuration, the voltage generators (210, 220) are arranged in series.

The voltage generators (210, 220) are separated through transformers (211, 222) placed at the outputs of each of the voltage generators (210, 220).

The transformer (211, 222) is provided with an output signal in a phase-shifted or dephased state, or in the opposite phase-shifted or dephased form if necessary.

According to a first embodiment, the electrotherapeutic device of the present invention includes measuring units (213, 223) each positioned at an output of a voltage generator (210, 220). Each of the measuring units (213, 223) is connected to a voltage generator (210) and a control module (214, 224) corresponding to the voltage generator (210, 220).

In the above embodiment according to the first configuration, the current flowing in the absence of the ground electrode (240) is the current (110) derived between the active electrodes (212, 222) applied to the body of the user (10), as shown in FIG. 3.

The signal of the first configuration is a line signal, and V110 = V120 + V121. V110 is the voltage of the current (110) circulating between the active electrodes (212, 222), V120 is the voltage of the current (120) circulating between the active electrode (212) and the absent ground electrode (240), and V121 is the voltage of the current (121) circulating between the active electrode (222) and the absent ground electrode (240).

In the first configuration, the nominal voltage value can be increased by up to two times by serializing the separated voltage generators (210, 220), thereby increasing the absorption rate of the living tissue (bone, ligament, etc.) and inducing an insulation breakdown effect that induces current flow within the tissue.

The first configuration enables serial diathermy treatment. This configuration allows for the serial configuration of voltage generators (210, 220) to generate a diathermy signal. The treatment is performed using two active electrodes and a ground electrode, which is a floating electrode that does not directly contact the user's body. This configuration increases only the voltage, not the intensity. The current maximizes the conductivity of biological tissue, accelerating wound healing while minimizing heat generation. The goal is to stimulate cellular metabolism in the tissue through voltages of up to 800 Vrms.

In the first configuration, the voltage generator (210, 220) may be provided so that the output signal is synchronized and in a dephased state.

According to one embodiment of the present invention, the second configuration shown in FIG. 3 can be applied alternately to the device.

According to a second configuration of the present invention, N=3, which includes active electrodes (212, 222) each connected to a voltage generator (210, 220). In the second configuration, the device also includes a ground electrode (240), which is connected to a common portion between the voltage generators (210, 220). In the second configuration, the voltage generators (210, 220) are arranged in parallel.

According to the second configuration including the ground electrode (240), the current flows between the active electrode (212, 222) and the ground electrode (240), but also circulates between the active electrode (212, 222) as depicted in FIG. 4.

In the second configuration, the signals of the currents (120, 121) are simple. The voltage generators (210, 220) each establish different impedances. As the active electrodes (212, 222) are applied to the body of the user (10), an impedance exists between the active electrodes (212, 222), and a voltage (V110) is generated between the active electrodes (212, 222). V110 varies depending on the distance between the active electrodes (212, 222) and whether the signals are dephased as specified above.

In the second configuration, the nominal voltage can be doubled by arranging the voltage generators (210, 220) in parallel, thereby heating the penetrating tissue. This is also called diathermy. The power can be varied as the active electrodes (212, 222) are positioned closer or further apart.

The second configuration allows for diathermy and mixed conduction therapy. This configuration allows for the application of diathermy and conduction-generating signals by arranging voltage generators (210, 220) in parallel. In the second configuration, a ground electrode (240) is positioned on the body of the user (10) to generate three current segments distributed among the three electrodes. The sum of the current segments (110, 120, 121) corresponds to the power of the electrotherapy device. The second configuration also promotes heating (diathermy) of the penetrating biological tissue by increasing only the intensity, not the voltage, up to a maximum of 4 amperes.

The active electrodes (212, 222) of FIGS. 4 and 5 transmit sinusoidal currents that may have different frequencies and characteristics. The two active electrodes converge to a ground electrode (240) via electrical segments through which currents (120, 121) flow, and at this time, a third electrical segment through which currents (110) flow can be generated depending on the setting of the ground electrode (240). The present invention can distribute power transmitted from a two-phase device through three electrical segments of three electrodes (212, 222, 240) on the body of a user (10). The electrical segments are positioned between the electrodes (212, 222, 240), and the therapist can decide how to distribute the power. The device can be equipped to synchronize/desynchronize through dephasing of the signals.

Figure 4 shows a phased or dephased synchronization signal, with no derived current.

Figure 5 shows a phased or dephased asynchronous signal, with one derived current.

In the second embodiment of the first configuration of FIG. 6, there are two active electrodes (N=2), each connected to a voltage generator (210, 220). In the second embodiment, the device does not include a ground electrode. In the first configuration, the voltage generators (210, 220) are arranged in series.

As shown in FIGS. 6 and 7, active electrodes (212, 222) are provided to allow current to flow to the introduction and output of one of the active electrodes, thereby simultaneously or alternately exhibiting activity/neutrality.

There are also embodiments featuring smart active electrodes, in which the device features an inertial system that monitors the therapist's movements in real time. The therapist can then adjust the treatment method to utilize the device more effectively. The inertial system can also detect the type of electrode being used, and the control module (214, 224) can adjust the output based on the detected electrode type.

For example, the device can handle a maximum simplex voltage of 400 Vrms, a maximum simplex current of 1.2 Arms, and a power of 150 W for a frequency in the range of 300 kHz to 1 MHz, and a maximum simplex voltage of 800 Vrms, a maximum simplex current of 2.4 Arms, and a power of 300 W for a frequency in the range of 300 kHz to 1 MHz.

Therefore, the present invention can advantageously change the voltage and intensity of the high-frequency current, utilize different intensities and frequencies, and selectively combine different electrodes.

The voltage generators (210, 220) can generate multi-frequency voltages through low-frequency, medium-frequency, and high-frequency signal modulation, as described herein. The voltage generator with the highest frequency is amplitude-modulated by the voltage generator with the lowest frequency. Each generator must provide power corresponding to its respective electrode and associated electrode, and the power is regulated according to the amplitude and phase shift of the generator.

According to this possibility, the electrotherapy device comprises a voltage generator 1 configured to generate a first voltage having a first frequency and having a first terminal and first and second output terminals, and a voltage generator configured to generate a second voltage having a second frequency exceeding the first frequency and having a third terminal and third and fourth output terminals. The device is characterized in that it comprises one transmitting channel and one receiving channel, with the first and third terminals being connected to the corresponding transmitting channels, and the second and fourth terminals being connected to the corresponding receiving channels, respectively.

This allows two voltages of different frequencies to be used as a single transmit and receive channel. In particular, the electrotherapeutic device can be controlled so that the first voltage generator generates a first voltage of a first frequency, and the second voltage generator generates a second voltage of a second frequency.

Preferably, the control device is configured to generate a signal associated with a sine wave voltage of a first frequency modulated with a third frequency within the transmission channel and a sine wave voltage of a third frequency modulated with a fourth frequency, wherein the signal is a sum of a voltage of the first voltage generating module and a voltage of the second voltage generating module.

In another aspect, the working process of the electrotherapy device is

a. A step of generating a first voltage of a first frequency using a first generator;

b. A step of generating a second voltage having a second frequency exceeding the first frequency using a second generator, wherein a. and b. occur simultaneously, and the two generators operate simultaneously.

According to one embodiment, the first voltage generator is configured to generate a sinusoidal voltage.

According to one embodiment, the first frequency falls within a first frequency band between 1 kHz and 10 kHz.

According to one embodiment, the first voltage generator is configured to generate a sinusoidal voltage of a first frequency modulated by a third frequency.

In one embodiment, the third frequency falls within a third frequency band between 1 Hz and 150 Hz.

In one embodiment, the third frequency is a sinusoidal voltage.

In the above embodiment, the device generates a mid-frequency sine wave signal, modulating a low-frequency signal (electrical stimulation) and combining it with a high-frequency sine wave signal (diathermy). This device combines the benefits of electrical stimulation and diathermy radiofrequency via the same channel, generating a non-invasive current that promotes the body's natural healing mechanisms and activates cellular metabolism. This method demonstrates remarkable effectiveness in rehabilitation, promoting rapid recovery of muscle and joint function.

As a result, a sinusoidal current of 1 kHz–10 kHz modulated with a frequency of 1 Hz–150 Hz is generated. Modulation of the stimulation current can avoid tetany in the excited muscle during electrical stimulation.
