Description

[Technical Field]

[0001] The present invention relates to an electronic device for therapeutic or cosmetic purposes, and is particularly useful in the field of electrotherapy, where it integrates two types of current products in a single channel, which are suitably combined: low frequency, medium frequency (electrical stimulation) and high frequency (radio frequency). [Background technology]

[0002] Electrotherapy is a safe, non-invasive technique that uses electricity for therapeutic purposes. This technique has been shown to be effective in relieving pain, strengthening muscle fibers, or accelerating the healing of living tissue. Three main frequency groups are low frequency (1Hz-150Hz) for superficial nerve stimulation, mid frequency (1kHz-10kHz) for deep nerve stimulation, and high frequency (100kHz-1.2MHz) for selective superficial or deep diathermy. Low frequency (LF) and mid frequency (MF) are commonly referred to as electrical stimulation, and high frequency (HF) is commonly referred to as radiofrequency.

[0003] These various types of electrotherapeutic currents circulate between two fixed or movable conductive plates that act as electrodes in contact with the skin. Therapists can use different types of currents sequentially. Low-frequency (1Hz-150Hz) currents, known as microcurrents, consist of pulsed heat for the treatment of chronic pain, inflammation, drainage, and muscle recruitment. They are generally characterized by lower pulse electrical properties than other forms of electrical stimulation current. Microcurrents are particularly well-suited for localized or superficial areas.

[0004] Mid-frequency (1kHz-10kHz) interferential current is a sine wave modulated with a low-frequency signal, providing excellent therapeutic compliance to the patient and allowing for deep penetration into the body. This current consists of a 1kHz-10kHz sine wave carrier with amplitude modulation, generating a low-frequency signal capable of contracting deep muscles with an analgesic effect. This current is particularly used to mobilize deep muscles essential for the patient's posture.

[0005] Therefore, electrical stimulation devices used for muscle strengthening are used independently or by a therapist such as a physical therapist.

[0006] Heat therapy has been used in physical therapy for several years and is divided into two types: superficial thermotherapy and deep thermotherapy. Deep thermotherapy methods include long-wave and short-wave diathermy, ultrasound, and contact radiofrequency. Contact radiofrequency, also known as high-frequency current, ranges from 100 kHz to 1.2 MHz. These types of deep thermotherapy methods are called diathermy.

[0007] There is also Thecatherapy, which uses TECAR (Transfer Energy Capacitive And Resistive, hereinafter referred to as "Theca") current. Thecatherapy is a contact radiofrequency treatment method, a type of electrical treatment that uses high-frequency current. This technology was developed in the early 1990s through the development of resistive electrodes, which generate contact radiofrequency current in the high-frequency band. In the dose-sensitive mode, resonance is greater in soft tissues such as muscles, while in the resistive mode, resonance is even greater in hard tissues such as ligaments and bones. The treatment wavelength band is generally 300kHz-1.2MHz.

[0008] Although there are various electrical treatment techniques, each treatment requires a different device, which makes the treatment protocol complicated. Also, if a therapist has specific equipment for each treatment field, the possibilities for utilizing various techniques are limited.

[0009] Therefore, there is a need to provide technological solutions that can optimize and simplify treatment.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Before considering the embodiments of the present invention in detail, optional features that can be used simultaneously or alternately are as follows:

[0023] According to one embodiment, the first power generating module (100) is adapted to generate a sinusoidal voltage.

[0024] According to one embodiment, the first frequency belongs to a first frequency band between 1 kHz and 10 kHz.

[0025] According to one embodiment, the first power generation module (100) is adapted to generate a sinusoidal voltage at a first frequency modulated to a third frequency.

[0026] According to one embodiment, the third frequency belongs to a third frequency band between 1 Hz and 150 Hz.

[0027] According to one embodiment, the third frequency is a sinusoidal voltage.

[0028] The present invention generates a medium-frequency sine wave signal to modulate a low-frequency signal (electrical stimulation) and combines it with a high-frequency sine wave signal (diathermy). The present invention combines the advantages of electrical stimulation and diathermy radio frequency on the same channel to generate a non-invasive current that activates the body's natural healing mechanisms and cellular metabolism. The present invention has excellent effects on rehabilitation through the rapid recovery of muscle and joint function.

[0029] The result is a 1-10 kHz sinusoidal current modulated to a frequency of 1-150 Hz. Modulation of the stimulation current can avoid tetany of the excited muscles during electrical stimulation.

[0030] According to one embodiment, the second power generation module (200) is provided for sinusoidal voltage generation.

[0031] According to one embodiment, the second frequency belongs to a second frequency band between 100 kHz and 10 MHz.

[0032] According to one embodiment, a second power generating module (200) is provided for generating a sinusoidal voltage at a second frequency modulated to a fourth frequency.

[0033] According to one embodiment, the fourth frequency belongs to a fourth frequency band between 1 Hz and 150 Hz.

[0034] According to one embodiment, the fourth frequency is a pulse.

[0035] According to one embodiment, the second power generation module (200) includes an activation control device (38) configured to generate a sinusoidal pulsed voltage at a fourth frequency.

[0036] According to one embodiment, the first power generating module (100) includes a transmission control device (37) configured to transmit voltage at the fourth frequency from the first power generating module.

[0037] According to one embodiment, the first power generating module (100) includes a first transformer (11) having a first inductance, and the second power generating module (200) includes a second transformer (21) having a second inductance, and the ratio of the first inductance to the second inductance is preferably greater than 500, more preferably greater than 1000.

[0038] According to one embodiment, the second power generating module (200) includes an output filter (24) and can be coupled to a second transformer (21) including an LC circuit with a coil (L) (26) and a capacitor (25).

[0039] According to one embodiment, the output filter (24) includes a resonant capacitor (27) for resonating at the second frequency of the second generator.

[0040] According to one embodiment, the control device is configured to vary the impedance of the transmission channel (4) when controlling the first power generation module (100).

[0041] According to one embodiment, the device generating impedance changes during the operation process of the electrotherapy device (1) when the first power generating module (100) is activated.

[0042] According to one embodiment, the second transformer (21) is isolated during the operation of the electrotherapy device (1) when the first power generating module (100) is activated, otherwise a short circuit may occur at the output of the first transformer (11) and it may not be able to generate output current.

[0043] According to one embodiment, during the operation of the electrotherapy device 1 with the second power generating module 200 activated, the first transformer 11 does not modulate the output sinusoidal voltage of the second transformer 21. The impedance it presents is negligible compared to the impedance of the user 30.

[0044] The present invention relates to an electrotherapy device (1) that includes two power generation modules (100, 200).

[0045] Preferably, the two power generating modules are separated.

[0046] The electrotherapy device (1) of the present invention can simultaneously combine a medium frequency interference current and a high frequency tectatherapy current, and preferably can combine pulses to simulate a low frequency microcurrent.

[0047] The electrotherapy device (1) of the present invention includes a first power generating module (100) including a first generator (10). The first generator (10) is configured to generate a first voltage at a first frequency. The first voltage is a sinusoidal voltage, and preferably, the first frequency can be in a first frequency band between 1 kHz and 10 kHz. This frequency band is considered a medium frequency type. An example of a medium frequency sinusoidal voltage is shown in FIG. 2A. This frequency band has a drainage effect and is useful for muscle recovery. The first power generating module (100) includes a first terminal (12) and a second terminal (13). The first power generating module (100) is used for electrical stimulation and deep muscle strengthening.

[0048] Preferably, the first power generation module (100) generates a medium frequency sinusoidal current between 1 kHz and 10 kHz to promote deep and effortless muscle recruitment through low frequency amplitude modulation.

[0049] According to a preferred embodiment, the first power generating module (100) of the present invention comprises a first transformer (11) associated with a first current generator (10).

[0050] The first power generation module (100) can include a first modulator configured to generate a third voltage that modulates the first voltage, preferably the third voltage being a sinusoidal voltage. For example, the first modulator can perform pulse width modulation (PWM).

[0051] The first modulator modulates the first frequency with a third frequency, which is lower than the first frequency. The third frequency is preferably located within a third frequency band lower than the first frequency band. The third frequency band is preferably between 1 Hz and 150 Hz. This frequency band is considered a low-frequency type.

[0052] The third frequency may be varied during operation. During operation of the first power generating module (100), the third frequency may be varied to modulate the first frequency, particularly according to the needs of the user. An example of a single low frequency signal is shown in Figure 2B. This signal is represented by a multiplier on the ordinate between 0 and 1.5.

[0053] Advantageously, a sine wave is generated quickly using primary switching. Pulse width modulation generates a sine wave whose amplitude can be modulated at a low frequency (1 Hz-150 Hz). This results in a sinusoidal voltage with an amplitude between 1 kHz and 10 Hz modulated at a frequency between 1 Hz and 150 Hz. An example of such modulation is shown in Figure 2C. Modulation of the stimulation current in electrical stimulation prevents tetani from occurring in the stimulated muscle.

[0054] The first power generation module (100) promotes deep and relaxed muscle contraction.

[0055] The electrotherapy device (1) of the present invention includes a second power generating module (200) including a second generator (20). The second generator (20) is configured to generate a second voltage having a second frequency, preferably a sinusoidal voltage. The second frequency exceeds the first frequency. Preferably, the second frequency falls within a second frequency band exceeding the first frequency band. Specifically, the second frequency band falls within a range of 100 kHz-10 MHz, more specifically, 100 kHz-1.2 MHz. This frequency band is considered to be of a high-frequency type. An example of a high-frequency voltage is shown in FIG. 3A. The second power generating module (200) includes a third terminal (22) and a fourth terminal (23). This second power generating module (200) is used to achieve a diathermic effect. This type of current accelerates the metabolism of living tissue through which the current passes.

[0056] The second power generation module (200) supplies high frequency sinusoidal current between 10 kHz and 10 MHz, more specifically between 100 kHz and 10 MHz, more specifically between 100 kHz and 1.2 MHz, along with low frequency pulses, where the high frequency generates a selective diathermic effect and the low frequency provides anti-inflammatory and pain relief effects.

[0057] The second power generation module (200) may include a second frequency generator activation control device (38). The activation control device (38) is configured to control the generator output at the second frequency by a fourth pulse frequency. The fourth frequency is lower than the second frequency. The fourth frequency may belong to a fourth frequency band lower than the second frequency band. Specifically, the fourth frequency band is between 1 Hz and 150 Hz. This frequency band is considered a low frequency type. An example of a pulse low frequency is shown in Figure 3B. The fourth frequency may also be referred to as a square wave.

[0058] The output voltage of the second power generating module (200) is a high frequency sinusoidal voltage emitted by a low frequency pulse. An example of this type of modulation is shown in Figure 3C.

[0059] According to a preferred embodiment of the present invention, the second power generating module (200) includes a second transformer (21) associated with the second generator (20).

[0060] Preferably, the device of the present invention includes an output filter (24) associated with the second transformer (21). The output filter (24) is used to filter the secondary coil of the second transformer (21). The output filter (24) generates a sine wave. This filter includes an LC circuit including an inductor (L) (26) and a capacitor (C) (25). Preferably, the output filter (24) includes a resonant capacitor (27) that can resonate at the operating frequency. The resonant capacitor (27) is located at the output of the inductor (26) and the capacitor (25). An example of modulation by the output of the output filter (24) using the electrical circuit shown in FIG. 1 is shown in FIG. 4. In this design, the third terminal (22) and the fourth terminal (23) are located at the terminals of the output filter (24).

[0061] The electrotherapy device (1) of the present invention includes a transmitting channel (4) and a receiving channel (5). Preferably, the first terminal (12) and the third terminal (22) are connected to the same transmitting channel (4), and the second terminal (13) and the fourth terminal (23) are connected to the same receiving channel (5).

[0062] Preferably, the transmission channel (4) is provided to be coupled to an electrode, in particular to the active electrode (2), which can be capacitive and / or resistive.

[0063] A receiving channel (5) can be provided to be connected to the neutral electrode (3), which can be fixed or movable.

[0064] The device according to the present invention is designed to apply a voltage to the body of a user 30. Preferably, an active electrode 2 is applied to the body of the user 30 to apply a current, and an indifferent electrode 3 is also applied to the body of the user 30 to receive the current provided by the active electrode 2 and passed through a portion of the body of the user 30.

[0065] According to one embodiment of the present invention, the voltage generated by the first power generating module (100) is emitted in pulses at the same frequency as the fourth frequency generated by the second power generating module (200). To this end, the first power generating module (100) preferably controls the emission of a first power generating module (100) output signal, which operates in pulses at the same frequency as the fourth frequency of the second power generating module (200) activation control device (38), through the transmission control device (37).

[0066] According to the present invention, two generators (10 and 20) can be combined to supply a high frequency sinusoidal current and a low frequency modulated medium frequency sinusoidal current to the transmission channel (4) as shown in FIG.

[0067] Thus, the present invention combines the advantages of electrical stimulation through low frequency current in muscle contraction with the advantages of radio frequency in providing diathermic therapeutic effects through high frequency current in a single transmission channel (4).

[0068] To successfully combine the two currents in the same transmission channel 4 without sacrificing these advantages, the present invention generates a sinusoidal medium-frequency current to transmit a low-frequency signal for electrical stimulation, and combines this with a high-frequency current for diathermy, preferably a sinusoidal low-frequency pulse. Desirably, the present invention generates a non-invasive current that promotes the body's natural healing mechanisms and stimulates cell replacement.

[0069] It also provides excellent rehabilitation effects by helping muscles and joints recover quickly.

[0070] It can also be used to relieve pain, relieve mechanical tension, stimulate blood and lymph circulation, strengthen deep muscles and / or accelerate the natural healing of damaged tissue.

[0071] According to the present invention, the first power generating module (100) and the second power generating module (200) simultaneously generate voltages.

[0072] Here, "simultaneously" refers to the first power generating module (100) generating a first voltage emitted from a transmission channel (4) and, for at least a given non-zero time, the second power generating module (200) generating a second voltage emitted from the same transmission channel (4). During this at least non-zero time, the active electrode (2) simultaneously supplies the first current and the second current to the user (30).

[0073] The device of the present invention may include a control device configured to control the voltage generation by the first power generation module (100) and the voltage generation by the second power generation module (200). Preferably, the control device may also be configured to control the current strength and voltage, the inductance of the generated current, and / or the impedance of the device.

[0074] According to a preferred embodiment of the present invention, the first transformer (11) has a first inductance and the second transformer (21) has a second inductance, with the ratio of the two inductances preferably being greater than 500, more preferably greater than 1000. For example, the first transformer (11) has a maximum inductance of 590 mH, and the second transformer (21) has a maximum inductance of at least 385 μH.

[0075] The impedance of the second power generating module is negligible compared to the impedance of the user 30. Therefore, the main path of current flow is through the user 30.

[0076] When the second generator (20) is activated, the first transformer (11) does not modify the sinusoidal voltage of the second transformer (21) due to the inductance, so no frequency interference occurs.

[0077] The present invention also provides a method of operating an apparatus, comprising the following operational steps:

[0078] a step (a) of generating a first voltage having a first frequency preferably within a first frequency band by a first power generation module (100);

[0079] a step (step b) of generating a second voltage having a second frequency within a second frequency band exceeding the first frequency band by a second power generation module (200);

[0080] Steps a and b are provided in a manner that they are performed simultaneously.

[0081] In Figure 1, the electrical circuit of the electrotherapy device (1) according to the present invention includes a first power generating module (100) and a second power generating module (200). The first power generating module (100) includes a first generator (10) and a first transformer (11). The generator (10) includes a half-bridge or full-bridge topology for generating a signal. Preferably, the generator (10) is a medium frequency generator controlled by PWM (pulse width modulation). The first power generating module (100) includes a first terminal (12) and a second terminal (13).

[0082] The first transformer (11) is connected to the terminals of the first generator (10). According to a non-limiting implementation, the first transformer (11) advantageously includes a first primary circuit (28) and a first secondary circuit (29) that include a mid-frequency filter using PWM. A mid-frequency filter below 10 kHz generates a sine wave from a square wave signal. Utilizing PWM optimizes filtering. A first terminal (12) and a second terminal (13) are located on the first secondary circuit (29) of the first transformer (11).

[0083] The second power generation module (200) includes a second generator (20) and a second transformer (21). The second generator (20) includes a half-bridge or full-bridge topology that generates a square wave signal. The second power generation module (200) includes a third terminal (22) and a fourth terminal (23).

[0084] The second transformer (21) is connected to the terminals of the second generator (20). In a non-limiting implementation, the second transformer (21) includes a second primary circuit (31) and a second secondary circuit (32). Preferably, as shown in FIG. 1, the device of the present invention includes an output filter (24) connected to the secondary coil terminals of the second transformer (21). The output filter (24) includes a coil (26), a capacitor (25), and a resonant capacitor (27). The third terminal (22) and the fourth terminal (23) are connected to the output filter (24). The output filter is a high-frequency filter. A high-frequency filter higher than 100 kHz generates a sine wave from a square wave signal. The coil (26), resistor (25), and resonant capacitor (27) structure allows resonance to improve the shape of the sine wave, preferably at a frequency (f0). For example, f0 is set to 400 kHz.

[0085] The first terminal (11) and the third terminal (21) are connected to the transmitting channel (4), and the second terminal (13) and the fourth terminal (23) are connected to the receiving channel (5).

[0086] Preferably, as shown, the transmit channel (4) is coupled to at least one active electrode (2) and the receive channel (5) is coupled to at least one indifferent electrode (3). The electrodes (2) and (3) are applied to the user (30).

[0087] The generators (10) and (20) are insulated.

[0088] FIG. 2 illustrates the voltage generated by the first power generating module (100).

[0089] 2A shows a first frequency (4 kHz in this case) within a first frequency band that corresponds to medium frequencies, and the voltage is a sinusoidal voltage (curve 35).

[0090] 2B shows a second frequency (50 Hz in this case) within a third frequency band, which corresponds to low frequencies, and the voltage is a sinusoidal voltage (curve 36).

[0091] Thus, the first power generating module (100) generates the sinusoidal voltage shown in Figure 2C, which is a 4 kHz medium frequency modulated 150% in amplitude by a low frequency (curve 35). The voltage is modulated 100% and then 50% by the low frequency modulation frequency.

[0092] FIG. 3 illustrates the voltage generated by the second power generation module (200).

[0093] 3A shows a second frequency (500 kHz in this case) within a second frequency band corresponding to high frequencies, and the voltage is a sinusoidal voltage (curve 33).

[0094] 3B shows a modulated signal at a fourth frequency (25 Hz in this case) within a fourth frequency band, which corresponds to low frequencies. The signal is a square wave signal. Therefore, the modulated signal is a pulse (curve 34).

[0095] Therefore, the second power generation module (200) generates the sinusoidal voltage shown in Figure 3C, which is a high frequency of 500 kHz modulated by a spherical low frequency. More details about the sinusoidal voltage shown in Figure 3A are shown in the box in Figure 3c, which shows a high frequency voltage modulated by a low frequency pulse.

[0096] FIG. 4 shows the sinusoidal voltage at the output of the transmitting channel (4) when two voltages are applied simultaneously. Here, the sinusoidal voltage is the sum of the first voltage generated by the first power generating module (100) and the second voltage generated by the second power generating module (200). The output signal of the transmitting channel (4) is a high-frequency and medium-frequency sinusoidal voltage modulated by a low-frequency. Here, the first voltage generated by the first power generating module (100) is also modulated by the low-frequency pulses of the second power generating module (200). To this end, as previously described, the device includes a voltage transmission control device (37) configured to transmit the first power generating module voltage to a fourth frequency. Therefore, here, we can see the low-frequency pulses (curve 34), the high-frequency pulses (curve 33), and the medium-frequency pulse (curve 35) modulated by the low-frequency pulse (curve 36) with an amplitude greater than 100%.
