Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to electrode current output circuits and therapeutic devices. Background Technology
[0002] EMS (Electrical Muscle Stimulation) and RF (Radio Frequency) are widely used in non-invasive beauty and body conditioning. EMS generates electrical stimulation current to stimulate muscles, while RF generates radio frequency current to heat the skin.
[0003] Currently available treatment products typically use RF or EMS as energy sources alone, and can only achieve muscle stimulation or skin heating in a single treatment. This results in long treatment cycles for beauty and body conditioning treatments.
[0004] Therefore, for cases with long treatment cycles, a combination of RF+EMS treatment is conventionally proposed. However, this method applies the generated electrical stimulation current and radiofrequency current to different sites simultaneously. Operators need to manually move the electrodes that generate electrical stimulation current and radiofrequency current according to the treatment situation to ensure that each site is treated with electrical stimulation current and radiofrequency current, which may result in poor treatment effects. Summary of the Invention
[0005] The main purpose of this application is to provide an electrode current output circuit and a therapeutic device, which aims to solve the technical problem of how to simultaneously apply electrical stimulation current and radio frequency current to the same site to avoid poor treatment results.
[0006] To achieve the above objectives, this application proposes an electrode current output circuit, which is applied to a therapeutic device. The therapeutic device is equipped with an electrode module, and the electrode current output circuit consists of at least one current output circuit, which includes:
[0007] The current coupling unit is used to filter the initial radio frequency current and the initial electrical stimulation current that flow in simultaneously to obtain the target radio frequency current and the target electrical stimulation current, and to couple the target radio frequency current and the target electrical stimulation current to obtain the coupling current.
[0008] The coupling current output terminal connected to the current coupling unit is used to output coupling current and apply the coupling current to the treatment area that is in contact with the target electrode. The electrode module includes at least one electrode, and the target electrode is an electrode connected to the coupling current output terminal.
[0009] In one embodiment, the current output circuit further includes a radio frequency current input terminal and an electrical stimulation current input terminal. The radio frequency current input terminal includes a first radio frequency positive electrode, and the electrical stimulation current input terminal includes an electrical stimulation positive electrode and an electrical stimulation negative electrode.
[0010] The positive electrode of electrical stimulation is connected to the first sub-output terminal of the coupling current output terminal via the first connecting line and the current coupling unit. The first sub-output terminal is connected to the first electrode region in the target electrode device.
[0011] The negative electrode of the electrical stimulation is connected to the second sub-output terminal of the coupling current output terminal via the second connecting line and the current coupling unit. The second sub-output terminal is connected to the second electrode region in the target electrode device, and an isolation gap is formed between the first electrode region and the second electrode region.
[0012] The first radio frequency positive electrode is connected to the first connection line via the third connection line and the current coupling unit, so as to transmit the target first radio frequency current to the first connection line and couple it with the target first electrical stimulation current on the first connection line to obtain the first coupling current.
[0013] The first radio frequency positive electrode is also connected to the second connection line via the fourth connection line and the current coupling unit, so as to transmit the target first radio frequency current to the second connection line and couple it with the target second electrical stimulation current on the second connection line to obtain the second coupling current.
[0014] The target radio frequency current includes a target first radio frequency current, the target electrical stimulation current includes a target first electrical stimulation current and a target second electrical stimulation current, and the coupling current includes a first coupling current and a second coupling current.

[0017] The electrode module includes a negative electrode component connected to the radio frequency negative output terminal, and the negative electrode component corresponds to the target electrode component.
[0018] In one embodiment, the electrode module is a unipolar radio frequency electrode module, which has multiple target electrodes and one negative electrode. When it is obtained that each target electrode is in contact with the treatment area and the negative electrode is in contact with the non-treatment area, the first sub-output terminal is controlled to output a first coupling current to the treatment area through the first electrode area, and the second sub-output terminal is controlled to output a second coupling current to the treatment area through the second electrode area.
[0019] The target first electrical stimulation current in the first coupling current flows into the second sub-output terminal in the treatment area through the second electrode area, and the target second electrical stimulation current in the second coupling current flows into the first sub-output terminal in the treatment area through the first electrode area, thereby forming an electrical stimulation circuit in the treatment area.
[0020] The target first radio frequency current in the first coupling current and the target first radio frequency current in the second coupling current flow into the radio frequency negative electrode through the negative electrode after passing through the non-treatment area in the treatment area.
[0021] In this case, the treatment area and the non-treatment area are under the same load.
[0022] In one embodiment, the electrode module is a bipolar radio frequency electrode module, which has multiple negative electrode components that correspond one-to-one with multiple target electrode components. When it is obtained that both the target electrode components and the negative electrode components are in contact with the treatment area, the first sub-output terminal is controlled to output a first coupling current to the treatment area through the first electrode area, the second sub-output terminal is controlled to output a second coupling current to the treatment area through the second electrode area, and the radio frequency negative electrode output terminal is controlled to output a second radio frequency current to the treatment area through the negative electrode component.

[0024] The target first radio frequency current in the first coupling current and the target first radio frequency current in the second coupling current flow into the radio frequency negative electrode in the treatment area through the negative electrode device, and the second radio frequency current flows into the first sub-output terminal in the treatment area through the first electrode area, or into the second sub-output terminal through the second electrode area, thereby forming a radio frequency circuit in the treatment area.
[0025] In one embodiment, the current coupling unit includes a first resonant network;
[0026] The first resonant network is connected between the positive electrode of the electrical stimulation and the first sub-output terminal through the first connecting line. It is used to filter the high-frequency signal in the initial first radio frequency current that is transmitted to the first connection point of the first connecting line and the third connecting line, so that the low-frequency signal in the initial first electrical stimulation current can be transmitted to the first sub-output terminal to form the target first electrical stimulation current.
[0027] The first resonant network includes a first inductor group and a first capacitor group connected in parallel;
[0028] The first end of the first inductor group is connected to the first end of the first capacitor group and connected to the positive electrode of the electrical stimulation. The second end of the first inductor group is connected to the second end of the first capacitor group and connected to the first sub-output terminal.
[0029] In one embodiment, the current coupling unit includes a second resonant network;
[0030] The second resonant network is connected between the negative electrode of the electrical stimulation and the second sub-output terminal via the second connecting line. It is used to filter the high-frequency signal in the initial first radio frequency current that is transmitted to the second connection point of the second connecting line and the fourth connecting line, so that the low-frequency signal in the initial second electrical stimulation current can be transmitted to the second sub-output terminal to form the target second electrical stimulation current.
[0031] The second resonant network includes a second inductor group and a second capacitor group connected in parallel;
[0032] The first end of the second inductor group is connected to the first end of the second capacitor group and is connected to the negative electrode of the electrical stimulation. The second end of the second inductor group is connected to the second end of the second capacitor group and is connected to the second sub-output terminal.
[0033] In one embodiment, the current coupling unit includes a high-pass network;
[0034] The Qualcomm network is connected between the first RF positive terminal and the first sub-output terminal via a third connection line, and the Qualcomm network is also connected between the first RF positive terminal and the second sub-output terminal via a fourth connection line;
[0035] Used to filter the low-frequency signal in the initial first electrical stimulation current input to the first connection point and the low-frequency signal in the initial second electrical stimulation current input to the second connection point, so that the high-frequency signal in the initial first radio frequency current can be input to the first sub-output terminal and the second sub-output terminal to form the target first radio frequency current.
[0036] Qualcomm networks include a third capacitor and a fourth capacitor;
[0037] The first terminal of the third capacitor and the first terminal of the fourth capacitor are connected and connected to the first radio frequency positive terminal.
[0038] The second terminal of the third capacitor is connected to the first connection line between the first resonant network and the first sub-output terminal via the third connection line.
[0039] The second terminal of the fourth capacitor is connected to the second connection line between the second resonant network and the second sub-output terminal via the fourth connection line.
[0040] In one embodiment, the radio frequency current input terminal further includes at least one second radio frequency positive electrode;
[0041] The second radio frequency positive electrode is connected to the third sub-output terminal of the coupling current output terminal via the sixth connection line and the resonant network. The third sub-output terminal is connected to the third electrode region in the target electrode device.
[0042] The third electrode region forms an isolation gap with the first electrode region and the second electrode region, respectively.
[0043] In addition, to achieve the above objectives, this application also provides a therapeutic device that includes the electrode current output circuit as described above.
[0044] One or more technical solutions proposed in this application have at least the following technical effects:
[0045] An electrode current output circuit for use in a therapeutic device is proposed. The electrode current output circuit consists of at least one current output circuit, which includes: a current coupling unit for filtering the simultaneously flowing initial radio frequency current and initial electrical stimulation current to obtain the target radio frequency current and the target electrical stimulation current, and coupling the target radio frequency current and the target electrical stimulation current to obtain a coupling current; and a coupling current output terminal connected to the current coupling unit for outputting the coupling current and applying the coupling current to the treatment area that is in contact with the target electrode. The electrode module includes at least one electrode, and the target electrode is an electrode connected to the coupling current output terminal.
[0046] This application uses a current coupling unit to couple radiofrequency current and electrical stimulation current into a coupling current, which is then output from an electrode connected to the output terminal of the coupling current and applied to the treatment area that is in contact with the electrode. Since the coupling current includes both radiofrequency current and electrical stimulation current, applying the coupling current to the treatment area that is in contact with the electrode is equivalent to simultaneously outputting radiofrequency current and electrical stimulation current to the same treatment area. This avoids the problem of poor treatment effect in conventional RF+EMS combined treatment methods and can achieve highly efficient multi-level combined treatment. Attached Figure Description

[0065] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0066] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0067] RF, as a type of radio frequency energy, can directly penetrate the skin, instantly raising the temperature of the dermis and stimulating the production of new collagen, thus achieving a lifting and wrinkle-reducing effect. It primarily utilizes the thermal effect. EMS, on the other hand, is an electrical stimulation energy that releases weak electrical currents to stimulate the muscle layer beneath the dermis, helping to restore the balance between muscles. Therefore, RF and EMS technologies are two commonly used technologies in therapeutic devices. The electrode module of the therapeutic device is attached to the skin to be treated, i.e., the treatment area. The device generates radio frequency energy and / or electrical stimulation energy, and the radio frequency current corresponding to the radio frequency energy and / or the electrical stimulation current corresponding to the electrical stimulation energy are passed through the electrode module to form a corresponding circuit under the treatment area, thereby achieving the therapeutic effect.
[0068] However, existing electrode modules can only output radiofrequency current or electrical stimulation current. Therefore, the treatment area attached to the electrode can only receive either radiofrequency or electrical stimulation current at any given time, making it impossible to simultaneously apply both types of current to the same treatment area and achieve two different therapeutic effects. This forces operators to adjust the electrode placement based on the current received in the previous treatment period, potentially leading to missed areas and reduced treatment effectiveness. Alternatively, using the same electrode to output radiofrequency and electrical stimulation current at different times also fails to achieve simultaneous treatment effects on the same area, hindering the reduction of total treatment time and resulting in suboptimal treatment outcomes.
[0069] Based on this, this application provides an electrode current output circuit 10, referring to... Figure 1 , Figure 1 This is a schematic diagram of the electrode current output circuit 10 of this application.
[0070] The electrode current output circuit 10 consists of at least one current output circuit, which includes: a current coupling unit for filtering the simultaneously flowing initial radio frequency current and initial electrical stimulation current to obtain the target radio frequency current and the target electrical stimulation current, and coupling the target radio frequency current and the target electrical stimulation current to obtain a coupling current; and a coupling current output terminal connected to the current coupling unit for outputting the coupling current and applying the coupling current to the treatment area that is in contact with the target electrode, wherein the electrode module includes at least one electrode, and the target electrode is an electrode connected to the coupling current output terminal.
[0071] To enable both radiofrequency current and electrical stimulation current to be applied simultaneously to a single treatment area via a single electrode, this embodiment proposes the following... Figure 1 The electrode current output circuit 10 shown includes a current coupling unit that couples the radio frequency current and the electrical stimulation current and transmits them to the coupling current output terminal in the electrode current output module. The coupling current output terminal is connected to only one electrode. Therefore, the coupled current is transmitted to the treatment area through the electrode connected to it via the coupling current output terminal, which can achieve the effect of simultaneous application of radio frequency current and electrical stimulation current to the same treatment area at the same time.
[0072] Specifically, after the control device enters the start-up state, the initial radio frequency current and the initial electrical stimulation current are simultaneously transmitted to the current coupling unit. The initial radio frequency current and the initial electrical stimulation current need to be filtered by the current coupling unit to ensure that the radio frequency current and the electrical stimulation current can be coupled. This avoids the high-frequency signal in the radio frequency current and the low-frequency signal in the electrical stimulation current from interfering with each other, which would prevent the radio frequency current and the electrical stimulation current from being transmitted to the coupling current output terminal normally, resulting in treatment failure.
[0073] The output after filtering is the target radiofrequency current and the target electrical stimulation current. Because of the filtering operation, the target radiofrequency current and the target electrical stimulation current can be coupled to a connecting line connected to the coupling current output terminal. They are simultaneously transmitted to the coupling current output terminal through this connecting line and then to an electrode connected to the coupling current output terminal. This allows the electrode to simultaneously form a corresponding treatment circuit in the treatment area, achieving heating of the dermis and stimulation of the muscle layer in the treatment area at the same time. This avoids the cumbersome process of the operator having to attach the electrode corresponding to the non-active current to the corresponding treatment area based on the current action of different treatment areas in the previous time period, thus eliminating the need for two currents to be applied to the same treatment area. Based on the electrode current output circuit 10 proposed in this embodiment, only one electrode needs to be attached to a treatment area, avoiding the cumbersome process and treatment errors that require attaching the electrode twice in the conventional method. At the same time, it enables the simultaneous output of the target radiofrequency current and the target electrical stimulation current by operating the current output once on one electrode in a certain time period, and simultaneously acting on the same treatment area to achieve two treatment effects. This avoids the defects of conventional methods that require outputting two treatment currents in different time periods based on one electrode, effectively shortening the total treatment time and improving the treatment effect.
[0074] It should be noted that the electrode module in this embodiment refers to a complete set of electrode components, such as electrode components corresponding to the cheeks, electrode components corresponding to the chin, and / or electrode components corresponding to the forehead, as well as radio frequency negative electrode components. As mentioned above, the coupling current generated by the current output circuit is output from one electrode component. Therefore, based on actual production needs, an electrode current output circuit composed of one or more current output circuits can be produced to generate an electrode module composed of electrode components and radio frequency negative electrode components corresponding to one or more components. The radio frequency negative electrode component can be shared with multiple electrode components.
[0075] First, the specific structure of the electrode current output circuit 10 proposed in this application will be described, and then the principle of solving the technical problem of this application will be explained based on the specific structure.
[0076] For details, please refer to Figure 2 As shown, the current output circuit also includes an RF current input terminal (i.e., Figure 2 and Figure 3 The IRF input and the electrical stimulation current input (i.e., the input of the IRF input) and the electrical stimulation current input terminal (i.e. Figure 2 and Figure 3 The IEMS input terminal includes a first RF positive electrode IRF+IN, and the electrical stimulation current input terminal includes an electrical stimulation positive electrode IEMS+IN and an electrical stimulation negative electrode IEMS-IN.
[0077] Electrical stimulation of the positive electrode IEMS+IN through the first connection line (i.e. Figure 2 and Figure 3 The wire marked "1" in the diagram is connected to the coupling current output terminal (i.e., the current coupling unit) via the current coupling unit. Figure 2 and Figure 3 The first sub-output terminal IEMS+ / IRF+OUT of the IEMS / IRF output enables the initial first electrical stimulation current connected from the positive electrode IEMS+IN to be output as the target first electrical stimulation current through the current coupling unit, and can be transmitted to the first sub-output terminal IEMS+ / IRF+OUT through the first connection line.
[0078] Simultaneously, the negative electrode IEMS-IN is electrically stimulated through the second connecting line (i.e. Figure 2 and Figure 3 The wiring marked "2" in the diagram is connected to the second sub-output terminal IEMS- / IRF+OUT of the coupling current output terminal via the current coupling unit, so that the initial second electrical stimulation current connected from the negative electrode IEMS-IN of the electrical stimulation is output as the target second electrical stimulation current through the current coupling unit and can be transmitted to the second sub-output terminal IEMS- / IRF+OUT through the second connection line.
[0079] When the therapeutic device only needs to output electrical stimulation energy, the structure of the positive electrode IEMS+IN-current coupling unit-first sub-output terminal IEMS+ / IRF+OUT and the negative electrode IEMS-IN-current coupling unit-second sub-output terminal IEMS- / IRF+OUT can simultaneously output the target first electrical stimulation current and the target second electrical stimulation current from the target electrode connected to the coupling current output terminal. An electrical stimulation circuit is formed in the muscle layer corresponding to the treatment area that is in contact with the target electrode. This allows for electrical stimulation treatment of the treatment area with only one electrode. Compared with the conventional scheme that requires two electrodes to form an electrical stimulation circuit for electrical stimulation treatment, this embodiment can significantly improve the utilization rate of the electrode.
[0080] The first radio frequency positive terminal IRF+IN is connected to the third connection line (i.e. Figure 2 and Figure 3The wiring marked "3" in the diagram is connected to the first connection line via the current coupling unit to transmit the target first radio frequency current to the first connection line and couple it with the target first electrical stimulation current on the first connection line to obtain the first coupling current. This allows the target first radio frequency current output from the first radio frequency positive electrode IRF+IN via the current coupling unit to be transmitted to the first connection line through the third connection line, coupled with the target first electrical stimulation current on the first connection line, and output from the first sub-output terminal IEMS+ / IRF+OUT. This enables a target electrode connected to the first sub-output terminal IEMS+ / IRF+OUT to output the first coupling current coupled with the target first radio frequency current and the target first electrical stimulation current.
[0081] At the same time, the first radio frequency positive electrode IRF+IN is also connected through the fourth connection line (i.e. Figure 2 and Figure 3 The wiring marked "4" in the diagram is connected to the second connection line via the current coupling unit to transmit the target first radio frequency current to the second connection line and couple it with the target second electrical stimulation current on the second connection line to obtain a second coupling current. This allows the target first radio frequency current output from the first radio frequency positive electrode IRF+IN via the current coupling unit to be transmitted to the second connection line through the fourth connection line, coupled with the target second electrical stimulation current on the second connection line, and output from the second sub-output terminal IEMS- / IRF+OUT. This enables a target electrode connected to the second sub-output terminal IEMS- / IRF+OUT to output a second coupling current coupled with the target first radio frequency current and the target second electrical stimulation current.
[0082] Because the first sub-output terminal IEMS+ / IRF+OUT and the second sub-output terminal IEMS- / IRF+OUT in a current output circuit are set on a coupled current output terminal, and a coupled current output terminal is connected to an electrode, and an electrode is attached to a treatment area, this embodiment can achieve simultaneous output of radiofrequency current and electrical stimulation current on the treatment area through a single electrode, thereby shortening the treatment cycle while ensuring the convenience of treatment operation.
[0083] The target radio frequency current includes a target first radio frequency current and a target second radio frequency current; the target electrical stimulation current includes a target first electrical stimulation current and a target second electrical stimulation current; the coupling current includes a first coupling current and a second coupling current; the initial radio frequency current includes an initial first radio frequency current and a second radio frequency current; and the initial electrical stimulation current includes an initial first electrical stimulation current and an initial second electrical stimulation current.
[0084] Depend on Figure 2It can be seen that the current output circuit also includes an RF negative output terminal IRF-OUT, and the RF current input terminal also includes an RF negative terminal IRF-IN. The RF negative terminal IRF-IN is connected through the fifth connection line (i.e. Figure 2 and Figure 3 The wiring marked "5" is connected to the radio frequency negative output terminal IRF-OUT. The electrode module includes a negative electrode component connected to the radio frequency negative output terminal IRF-OUT, and the negative electrode component corresponds to the target electrode component.
[0085] Because the electrode that outputs the first radio frequency current needs to cooperate with the negative electrode that outputs the second radio frequency current in order to form a radio frequency loop in the treatment area and achieve the heating effect on the treatment area, the current output circuit in this embodiment also includes a structure in which the radio frequency negative electrode IRF-IN is connected to the radio frequency negative electrode output terminal IRF-OUT through the fifth connecting line. This allows the second radio frequency current connected from the radio frequency negative electrode IRF-IN to be adjusted by the power of the matching element set on the fifth connecting line, and the adjusted second radio frequency current is transmitted to the radio frequency negative electrode output terminal IRF-OUT through the fifth connecting line. The second radio frequency current is then transmitted to the non-treatment area that is in contact with the middle electrode through the middle electrode connected to the radio frequency negative electrode output terminal IRF-OUT, forming a radio frequency loop with the positive radio frequency current output by the target electrode.
[0086] In addition, according to Figure 2 It can be seen that the first sub-output terminal IEMS+ / IRF+OUT and the second sub-output terminal IEMS- / IRF+OUT in the coupling current output terminal of the current output circuit proposed in this embodiment can output positive radio frequency current respectively. That is, one target electrode can output two positive radio frequency currents. The two output positive radio frequency currents form two radio frequency loops through the treatment area and the second radio frequency current on the intermediate electrode. Therefore, compared with the conventional method where one electrode can only output one positive radio frequency current, this embodiment has a better radio frequency treatment effect on the treatment area and improves the treatment effect of one target electrode on one treatment area.
[0087] The reason why a target electrode can simultaneously output the first target electrical stimulation current, the second target electrical stimulation current, and the positive radio frequency current without short-circuiting the electrical stimulation current is that a target electrode is divided into at least two electrode regions, and there is a certain isolation distance between the electrode regions so that the electrode regions do not affect each other. Each electrode region will output one positive radio frequency current, but an electrode region can only output one target first electrical stimulation current or one target second electrical stimulation current. That is, an electrode region can simultaneously output one positive radio frequency current and one target first / second electrical stimulation current, and there must be at least two electrode regions in a target electrode for outputting one target first electrical stimulation current and one target second electrical stimulation current, respectively.
[0088] In one feasible implementation, the radio frequency current input terminal further includes at least one second radio frequency positive terminal;
[0089] The second radio frequency positive electrode is connected to the third sub-output terminal of the coupling current output terminal via the sixth connection line and the resonant network. The third sub-output terminal is connected to the third electrode region in the target electrode device. The third electrode region forms an isolation gap with the first electrode region and the second electrode region respectively.
[0090] To enhance the therapeutic effect of radiofrequency current, this embodiment proposes that a separate radiofrequency current channel can be set in the current output circuit, that is, in Figure 3 Based on this, an additional IRF input is added to set the second radio frequency positive electrode. This second radio frequency positive electrode is connected to the initial second radio frequency current. The initial second radio frequency current is transmitted through the sixth connection line to a resonant network that is independent of the first resonant network 301 and the second resonant network 302. The high-frequency signal of the initial second radio frequency current is filtered by this resonant network to form the target second radio frequency current. After the target second radio frequency current is formed, it is transmitted to the third sub-output terminal of the coupling current output terminal. The third sub-output terminal is controlled to output the target second radio frequency current IRF+ to the treatment area through the third electrode area.
[0091] Specifically, such as Figure 4 As shown, this embodiment divides a target electrode into four electrode regions. Electrode region b is designated as the first electrode region for connection to the first sub-output terminal, electrode region d is designated as the second electrode region for connection to the second sub-output terminal, and electrode regions a and c are designated as the third electrode region for connection to the third sub-output terminal. Each of these four electrode regions can output a positive radiofrequency current IRF+, while electrode region b also outputs a target first electrical stimulation current IEMS+, and electrode region d also outputs a target second electrical stimulation current IEMS-. By dividing the target electrode into electrode regions, the treatment failure caused by electrical stimulation short circuits in the output of the target first and second electrical stimulation currents from a single electrode region is avoided. Furthermore, the electrode regions outputting the radiofrequency current can be dynamically adjusted based on actual treatment needs.
[0092] In one feasible embodiment, see [reference] Figure 3 As shown, the current coupling unit includes a first resonant network 301;
[0093] The first resonant network 301 is connected via a first connecting line between the positive electrode IEMS+IN and the first sub-output terminal IEMS+ / IRF+OUT, and is used to control the input to the first connection point (i.e., the connection point between the first connecting line and the third connecting line) Figure 3 The high-frequency signal in the initial first radio frequency current (marked as "A") is filtered to allow the low-frequency signal in the initial first electrical stimulation current to be transmitted to the first sub-output terminal IEMS+ / IRF+OUT to form the target first electrical stimulation current. This avoids interference from the high-frequency signal in the initial first radio frequency current transmitted to the first connection point, which would otherwise reduce the performance and accuracy of the low-frequency signal in the initial first electrical stimulation current and cause it to fail to output correctly.
[0094] in, Figure 3 The first resonant network 301 and the second resonant network 302 shown are only one possible implementation. The number of inductors and capacitors in the first resonant network 301 and the second resonant network 302 can be adjusted according to the actual filtering requirements.
[0095] Figure 3 The first resonant network 301 includes a first inductor group and a first capacitor group connected in parallel. The first end of the first inductor group is connected to the first end of the first capacitor group and connected to the positive electrode IEMS+IN of the electrical stimulation. The second end of the first inductor group is connected to the second end of the first capacitor group and connected to the first sub-output terminal IEMS+ / IRF+OUT.
[0096] In this embodiment, the first inductor group includes one inductor (hereinafter referred to as the first inductor L1), and the first capacitor group includes one capacitor (hereinafter referred to as the first capacitor C1). The first inductor L1 and the first capacitor form the first resonant network 301, and the resonant frequency of the first resonant network 301 is [missing information]. The first resonant network 301 is used as a band-stop filter to filter the high-frequency signal in the initial first radio frequency current input to the first connection line, that is, to suppress the interference of the high-frequency signal, so as to ensure that the initial first electrical stimulation current with low frequency signal on the first connection line can be used as the target first electrical stimulation current and normally transmitted to the first sub-output terminal IEMS+ / IRF+OUT to realize the output of the target first electrical stimulation current.
[0097] Further reference Figure 3 The current coupling unit includes a second resonant network 302. It should be noted that the circuit structures of the first resonant network 301 and the second resonant network 302 in the same current output circuit are the same.
[0098] The second resonant network 302 is connected via a second connecting line between the electrical stimulation negative electrode IEMS-IN and the second sub-output terminal IEMS- / IRF+OUT, and is used to control the input to the second connection point (i.e., the connection point between the second connecting line and the fourth connecting line) Figure 3The high-frequency signal in the initial first radio frequency current (marked as "B") is filtered to allow the low-frequency signal in the initial second electrical stimulation current to be transmitted to the second sub-output terminal IEMS- / IRF+OUT, forming the target second electrical stimulation current. This avoids interference from the high-frequency signal in the initial first radio frequency current transmitted to the second connection point, which would otherwise reduce the performance and accuracy of the low-frequency signal in the initial second electrical stimulation current. This would result in the low-frequency signal in the output first electrical stimulation current not being able to be output normally with the first electrical stimulation current, thus causing the electrical stimulation treatment for the treatment area to fail.
[0099] The second resonant network 302 includes a second inductor group and a second capacitor group connected in parallel. The first end of the second inductor group is connected to the first end of the second capacitor group and connected to the electrical stimulation negative electrode IEMS-IN. The second end of the second inductor group is connected to the second end of the second capacitor group and connected to the second sub-output terminal IEMS- / IRF+OUT.
[0100] Because the second resonant network 302 and the first resonant network 301 are on the same current output circuit, the second inductor group in the second resonant network 302 includes an inductor (hereinafter referred to as the second inductor L2), and the second capacitor group includes a capacitor (hereinafter referred to as the second capacitor C2). The second inductor L2 and the second capacitor form the second resonant network 302, and the resonant frequency of the second resonant network 302 is [missing information]. The second resonant network 302 is used as a band-stop filter to filter the high-frequency signal in the initial first radio frequency current input to the second connection line, that is, to suppress the interference of the high-frequency signal, so as to ensure that the initial second electrical stimulation current with low-frequency signal on the second connection line can be used as the target second electrical stimulation current and normally transmitted to the second sub-output terminal IEMS- / IRF+OUT, so as to realize the output of the target second electrical stimulation current and form a complete electrical stimulation circuit with the target first electrical stimulation current output on the first sub-output terminal IEMS+ / IRF+OUT.
[0101] The parameters related to the resonant frequencies in the first resonant network 301 and the second resonant network 302 are explained here: π is the mathematical constant pi, L is the inductance value, and C is the capacitance value.
[0102] In practical applications, depending on the impedance requirements of the RF current, a first inductor group and a first capacitor group, as well as a second inductor group and a second capacitor group, can be added in parallel. That is, the first resonant network 301 can be connected in series with multiple parallel first inductor groups and first capacitor groups, and the second resonant network 302 can be connected in series with multiple parallel second inductor groups and second capacitor groups. The inductors in the resonant network must be selected with low DC resistance and a high quality factor, and the capacitors must be selected with appropriate voltage ratings to ensure that the capacitors are not damaged under high-voltage power signals.
[0103] Further reference Figure 3 The current coupling unit also includes a Qualcomm network 303, which is connected between the first RF positive terminal IRF+IN and the first sub-output terminal IEMS+ / IRF+OUT via a third connection line. The Qualcomm network 303 is also connected between the first RF positive terminal IRF+IN and the second sub-output terminal IEMS- / IRF+OUT via a fourth connection line.
[0104] This is used to filter the low-frequency signal in the initial first electrical stimulation current input to the first connection point and the low-frequency signal in the initial second electrical stimulation current input to the second connection point, respectively, so that the high-frequency signal in the initial first radio frequency current can be input to the first sub-output terminal IEMS+ / IRF+OUT and the second sub-output terminal IEMS- / IRF+OUT to form the target first radio frequency current. This avoids interference or shielding of the initial first radio frequency current by the low-frequency signal in the initial first electrical stimulation current input to the first connection point, so that the high-frequency signal in the initial first radio frequency current cannot be accurately input to the first sub-output terminal IEMS+ / IRF+OUT.
[0105] Similarly, by using the Qualcomm network 303, the low-frequency signal in the initial second electrical stimulation current at the second connection point is prevented from interfering with or blocking the initial first radio frequency current. This prevents the high-frequency signal in the initial first radio frequency current from being accurately transmitted to the second sub-output terminal IEMS- / IRF+OUT, thus preventing the formation of a complete radio frequency circuit in the treatment area and leading to the failure of radio frequency therapy in the treatment area.
[0106] The Qualcomm network 303 includes a third capacitor C3 and a fourth capacitor C4;
[0107] The first terminal of the third capacitor C3 is connected to the first terminal of the fourth capacitor C4 and connected to the first RF positive terminal IRF+IN. The second terminal of the third capacitor C3 is connected to the first connection line between the first resonant network 301 and the first sub-output terminal IEMS+ / IRF+OUT through the third connection line.
[0108] The connection structure between the third capacitor C3 and the first radio frequency positive terminal IRF+IN forms a high-pass network 303 targeting the low-frequency signal in the initial first electrical stimulation current at the first connection point. The capacitive reactance of the third capacitor C3 is... The low-frequency signal in the initial first electrical stimulation current input to the first connection line is filtered, that is, the interference of the low-frequency signal is suppressed, so as to ensure that the initial first radio frequency current with high-frequency signal on the first connection line can be used as the target first radio frequency current and normally transmitted to the first sub-output terminal IEMS+ / IRF+OUT to realize the output of the target first radio frequency current.
[0109] Simultaneously, the second terminal of the fourth capacitor C4 is connected via a fourth connection line to the second connection line between the second resonant network 302 and the second sub-output terminal IEMS- / IRF+OUT. Through the connection structure between the fourth capacitor C4 and the first RF positive terminal IRF+IN, a high-pass network 303 is formed for the low-frequency signal in the initial second electrical stimulation current at the second connection point. The capacitive reactance of the fourth capacitor C4... The low-frequency signal in the initial second electrical stimulation current input to the second connection line is filtered, that is, the interference of the low-frequency signal is suppressed, so as to ensure that the initial first radio frequency current with high frequency signal on the second connection line can be used as the target first radio frequency current and normally transmitted to the second sub-output terminal IEMS- / IRF+OUT to realize the output of the target first radio frequency current.
[0110] It should be noted that, since the target first electrical stimulation current and target first radio frequency current at the first connection point, and the target second electrical stimulation current and target first radio frequency current at the second connection point are all currents after corresponding filtering operations, the interference between high-frequency signals and low-frequency signals on the corresponding currents will be reduced, so that the target first electrical stimulation current and target first radio frequency current, and the target second electrical stimulation current and target first radio frequency current can be coupled on a single connection line, achieving simultaneous transmission without mutual interference.
[0111] Among them, a third inductor L3 can be connected between the first RF positive terminal IRF+IN and the third capacitor C3 and the fourth capacitor C4. The third capacitor C3 serves as an impedance matching element to ensure that the first RF current can be output to the coupling current output terminal with the required power. That is, the output power of the first RF current is related to the inductance value of the third inductor L3.
[0112] A fifth capacitor C5 and a sixth capacitor C6 are connected in series between the RF negative terminal IRF-IN and the RF negative terminal output terminal IRF-OUT. The fifth capacitor C5 serves as an impedance matching element to ensure that the RF current can be output to the RF negative terminal output terminal IRF-OUT with the required power. That is, the output power of the second RF current is related to the capacitance value of the fifth capacitor C5. The sixth capacitor C6 is a capacitor set to meet safety requirements.
[0113] In practical applications, the third inductor L3 and the fifth capacitor C3 can be deleted or replaced as needed. They can be replaced with an oscillation circuit, a π-type inductor-capacitor network, or a resistor can be added directly after the second terminal of the third inductor L3.
[0114] The following is an explanation of the principles for solving the technical problems of this application based on a specific structure.
[0115] In a first feasible embodiment, combined with Figure 5 To explain, when the electrode module is a unipolar radio frequency electrode module, there are by default multiple target electrode components EC and one negative electrode component corresponding to each of the multiple target electrode components EC. When it is obtained that each target electrode component EC is in contact with the treatment area and the negative electrode component is in contact with the non-treatment area, the first sub-output terminal is controlled to output a first coupling current to the treatment area through the first electrode area R1 and the second sub-output terminal is controlled to output a second coupling current to the treatment area through the second electrode area R2.
[0116] The target first electrical stimulation current in the first coupling current flows into the second sub-output terminal through the second electrode region in the treatment area, and the target second electrical stimulation current in the second coupling current flows into the first sub-output terminal through the first electrode region R1 in the treatment area, thereby forming an electrical stimulation circuit in the treatment area; the target first radio frequency current in the first coupling current and the target first radio frequency current in the second coupling current flow into the radio frequency negative electrode through the negative electrode after passing through the non-treatment area in the treatment area, thereby forming a radio frequency circuit in the treatment area, wherein the treatment area and the non-treatment area are on the same load.
[0117] Taking the RF negative output terminal of the electrode current output terminal as an example, which is connected to a single negative electrode device. Figure 5 In the case where the electrode module of the therapeutic device is a monopolar radio frequency electrode module, this embodiment presents a schematic diagram showing the effect of the radio frequency current and electrical stimulation current output by the two target electrode ECs connected to any two coupled current output terminals in the electrode current output circuit in the treatment area.
[0118] As shown in the figure, the coupling current transmitted to the treatment area by a target electrode EC includes a target first radiofrequency current, a target first electrical stimulation current, and a target second electrical stimulation current. After the target first radiofrequency current is transmitted into the dermis of the treatment area through its corresponding target electrode EC, it flows into the corresponding radiofrequency negative electrode according to the non-treatment area where the negative electrode is attached, forming a radiofrequency circuit in the treatment area. With the initial voltage value of the first radiofrequency current remaining constant, the power of the radiofrequency field formed by the radiofrequency circuit will increase, thereby enhancing the radiofrequency energy and increasing the depth of penetration into the dermis, which can improve the radiofrequency treatment effect to a certain extent. The radiofrequency circuit corresponds to... Figure 5 The red dashed line in the middle.
[0119] After the target first electrical stimulation current and the target second electrode stimulation current are transmitted to the muscle layer of the treatment area, an electrical stimulation circuit is formed directly on the muscle layer corresponding to the first electrode region R1 and the second electrode region R2 in the target electrode EC. That is, an electrical stimulation field is formed on the corresponding muscle layer through a target electrode EC, which heats the dermis layer of the treatment area while stimulating the muscle layer of the treatment area. The electrical stimulation circuit corresponds to… Figure 5 The blue dashed line in the middle.
[0120] In a second feasible embodiment, combined with Figure 6 To explain, when the electrode module is a bipolar radio frequency electrode module, there are by default multiple negative electrode components corresponding one-to-one with the multiple target electrode components EC. When it is obtained that both the target electrode component EC and the negative electrode component are in contact with the treatment area, a first coupling current is output to the treatment area through the first electrode area R1, the second coupling current is output to the treatment area through the second electrode area R2 through the second sub-output terminal, and the second radio frequency current is output to the treatment area through the negative electrode component through the radio frequency negative electrode output terminal.
[0121] The target first electrical stimulation current in the first coupling current flows into the second sub-output terminal in the treatment area through the second electrode region R2, and the target second electrical stimulation current in the second coupling current flows into the first sub-output terminal in the treatment area through the first electrode region R1, thereby forming an electrical stimulation circuit in the treatment area; the target first radio frequency current in the first coupling current and the target first radio frequency current in the second coupling current flow into the radio frequency negative electrode in the treatment area through the negative electrode, and the second radio frequency current flows into the first sub-output terminal in the treatment area through the first electrode region R1, or into the second sub-output terminal through the second electrode region R2, thereby forming a radio frequency circuit in the treatment area.
[0122] Figure 6In the case where the electrode module of the therapeutic device is a bipolar radio frequency electrode module, this embodiment illustrates the effect of the radio frequency current and electrical stimulation current output by a target electrode EC connected to any one of the coupling current output terminals in the electrode current output circuit in the treatment area.
[0123] As shown in the figure, the coupling current transmitted to the treatment area by a target electrode EC includes a target first radiofrequency current, a target first electrical stimulation current, and a target second electrical stimulation current. After the target first radiofrequency current is transmitted to the dermis of the treatment area through its corresponding target electrode EC, it flows into the radiofrequency negative electrode corresponding to the negative electrode, depending on the treatment area to which the negative electrode is attached. Simultaneously, the second radiofrequency current is transmitted to the dermis of the non-treatment area through its corresponding negative electrode, and then flows into the target first radiofrequency positive electrode, depending on the treatment area to which the target electrode is attached. A radiofrequency loop is formed between the two treatment areas. With the initial voltage value of the first radiofrequency current remaining constant, the power of the radiofrequency field formed by these two radiofrequency loops will increase, thereby enhancing the radiofrequency energy and increasing the depth of dermal penetration, which can improve the radiofrequency treatment effect to a certain extent. The radiofrequency loop corresponds to… Figure 6 The red dashed line in the middle.
[0124] After the target first electrical stimulation current and the target second electrode stimulation current are transmitted to the muscle layer of the treatment area, an electrical stimulation circuit is formed directly on the muscle layer corresponding to the first electrode region R1 and the second electrode region R2 in the target electrode EC. That is, an electrical stimulation field is formed on the corresponding muscle layer through a target electrode EC. While heating the dermis layer of the treatment area corresponding to the target electrode EC, the muscle layer in the treatment area is stimulated. The electrical stimulation circuit corresponds to... Figure 6 The blue dashed line in the middle.
