[0041] The core of the present utility model is to provide an electric stimulation intensity and negative pressure linkage control system and an electric stimulation therapeutic apparatus. The control module can flexibly adjust the intensity of the electric stimulation signal and the negative pressure in the suction cup of the target electrode according to the treatment requirements, thereby avoiding skin problems caused by a constantly constant negative pressure value and improving the user experience.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an electric stimulation intensity and negative pressure linkage control system provided by the present utility model; please refer to Figure 2 , Figure 2 which is a schematic structural diagram of an electric stimulation therapeutic apparatus provided by the present utility model, where the electrode marked with + is the first electrode and the electrode marked with - is the second electrode; to solve the above technical problems, the present utility model provides an electric stimulation intensity and negative pressure linkage control system, including:

[0044] An electric stimulation signal generation module, whose control end is connected to the output end of the control module 3, the first output end is connected to the first electrode of the target electrode 4, and the second output end is connected to the second electrode of the target electrode 4, and is used to output a corresponding electric stimulation signal based on the control of the control module 3;

[0045] A current detection module 12, whose input end is connected to the output end of the electric stimulation signal generation module, and is used to detect the current value of the electric stimulation signal output by the electric stimulation signal generation module;

[0046] An air pump 21, whose input end is connected to the output end of the control module 3;

[0047] A pressure detection module 22, whose input end is respectively connected to the output end of the air pump 21 and the suction cup of the target electrode 4, and is used to detect the pressure value in the suction cup of the target electrode 4;

[0048] A control module 3, whose input end is respectively connected to the output ends of the current detection module 12 and the pressure detection module 22, and is used to adjust the suction force of the air pump 21 based on the current value and / or the pressure value, and adjust the intensity of the electric stimulation signal output by the electric stimulation signal generation module based on the current value.

[0049] It is not difficult to understand that, on the one hand, the control module 3 controls the electrical stimulation signal generation module to generate medium-frequency electrical stimulation signals according to the treatment requirements. The electrical stimulation signals are output to the target electrode 4, flowing in from the first electrode of the target electrode 4 and flowing out from the second electrode, thus forming a treatment loop. At the same time, a current detection module 12 is installed on the output side of the electrical stimulation signal generation module to detect the electrode output current, and the detected current value is transmitted to the control module 3 as a feedback signal. Through the circuit closed-loop control loop composed of the electrical stimulation signal generation module, the current detection module 12 and the control module 3, the control module 3 can realize the adjustment and output control of the generated electrical stimulation signals. On the other hand, the control module 3 also outputs control signals to control the working process of the air pump 21 according to the actual application requirements. The output end of the air pump 21 is connected to the suction cup of the target electrode 4. The control module 3 can adjust the pressure in the suction cup of the target electrode 4 by controlling the suction force of the air pump 21, so as to realize the adjustment process of the negative pressure value during the electrode negative pressure adsorption process and avoid the influence on the patient caused by the long-term unchanged negative pressure value. Through the air circuit closed-loop control loop composed of the air pump 21, the air pressure detection module 22 and the control module 3, the control module 3 can effectively realize the adjustment process of the adsorption situation of the target electrode 4.

[0050] It can be understood that the control module 3 can further realize the associated adjustment of the intensity of the output electrical stimulation signal and the negative pressure value of the electrode adsorption through the control of the circuit closed-loop control loop and the air circuit closed-loop control loop. For example: as the output intensity of the electrical stimulation signal increases, the negative pressure value in the adsorption bowl of the electrode gradually increases; as the output intensity of the electrical stimulation signal increases, the negative pressure value in the adsorption bowl of the electrode gradually decreases; when the electrical stimulation signal is output intermittently, the negative pressure value in the adsorption bowl of the electrode also changes intermittently; after the output of the electrical stimulation signal changes from strong to weak, a periodic fluctuation is generated by adjusting the negative pressure value of the electrode adsorption to produce a massage effect; in addition, the adsorption negative pressure of the electrode can also be adjusted according to the length of the treatment time. Taking the treatment time of 10 minutes as an example, as the electrical stimulation treatment time increases, the negative pressure value in the adsorption bowl of the electrode gradually weakens, and at the end of the treatment time, the pressure in the adsorption bowl of the electrode only needs to meet the requirement that the electrode adsorption does not fall off. There are various choices for the specific adjustment method of the adsorption pressure of the electrode by the control module 3 through the air pump 21. This application does not make a special limitation here, and is not limited to the adjustment of the adsorption pressure according to the intensity of the electrical stimulation signal and the length of the treatment time proposed in this application. The adjustment method of the adsorption pressure can be set according to the actual application requirements.

[0051] It is not difficult to understand that there are various implementation manners for the correlation relationship between the adjustment process of the output electrical stimulation signal by the control module 3 and the adjustment process of the adsorption negative pressure value of the adjustment electrode. The negative pressure value can be set to be proportional to the intensity of the electrical stimulation signal, or the correlation relationship between parameters such as the amplitude, period, and modulation depth of the electrical stimulation signal and the negative pressure value can be set. For how the control module 3 coordinates the two adjustment processes and the specific process of adjusting the electrical stimulation signal and the electrode adsorption negative pressure value through which correlation relationship can be adjusted and set according to the treatment effect in actual applications, and it is not limited to adjusting the adsorption pressure according to the intensity of the electrical stimulation signal and the length of the treatment time proposed in this application. This application does not make special limitations here. The control of the electrical stimulation signal generation module by the control module 3 is not limited to adjusting the signal intensity, and other parameters of the electrical stimulation signal, including amplitude, period, modulation depth, etc., can also be adjusted.

[0052] It should be noted that this application does not make special limitations here on the specific types and implementation manners of the target electrode 4, the electrical stimulation signal generation module, the current detection module 12, the air pump 21, the air pressure detection module 22, and the control module 3. A set of target electrodes 4 requires a pair of electrodes, that is, a first electrode and a second electrode to be realized. The specific material, shape, and size of the electrodes can all be adjusted according to the actual application situation. The current detection module 12 can be realized by means of a current transformer, etc., and the air pressure detection module 22 can be realized by means of an air pressure sensor, etc. The air pressure sensor is installed between the electrode suction cup and the air pump 21 to detect the pressure change in the adsorption bowl. The control module 3 can be realized by means of a microprocessor, a control chip, etc. The suction cup of the target electrode 4 is the adsorption device of the electrode, and there are various implementation manners. This application does not make special limitations here and is not limited to the form of the suction cup or adsorption bowl adopted in this application. A processing circuit for the electrical stimulation signal and a driving circuit for the air pump 21 can also be added and set in the circuit according to requirements. This application does not make special limitations here.

[0053] In actual applications, multiple sets of target electrodes 4 and several electrical stimulation intensity and negative pressure linkage control systems corresponding to each set of target electrodes 4 are set to implement the entire electrode system. Each electrical stimulation intensity and negative pressure linkage control system can adopt the same control module 3. Each set of target electrodes 4 is adsorbed at different positions on the human body according to application requirements. The control module 3 can comprehensively consider the treatment requirements and the adsorption positions of each set of target electrodes 4 to control the intensity of the electrical stimulation signal of each set of target electrodes 4 and the adsorption pressure conditions of each set of target electrodes 4.

[0054] It is not difficult to understand that the electrostimulation intensity and negative pressure linkage control system provided by the present utility model is applicable to physiotherapy scenarios with electrostimulation signal output and negative pressure adsorption in multi-channel medium frequency, interference current, and roaming current modes, and can be widely applied to various circuits and devices that utilize electrode adsorption to achieve functions such as treatment. The frequency and intensity of the generated electrostimulation signal can be set and adjusted according to the actual application scenario, and no special limitation is made herein for this application.

[0055] As a specific embodiment, for example Figure 2 shown, taking the application scenario of medium frequency electrostimulation signal as an example. An electrostimulation intensity and negative pressure linkage control system can form two closed-loop control circuits. The first closed-loop control circuit consists of a control module 3, an electrostimulation signal generation module including a signal conditioning and amplification circuit and a transformer, a current detection module 12, a roaming switching circuit 31, and a target electrode 4, and can realize the adjustment and control of the output intensity of the electrostimulation signal. The second closed-loop control circuit consists of a power control circuit, an air pump 21, an air hose, a three-way joint, a pressure detection module 22, a shunt, and a target electrode 4, and can realize the pressure adjustment in the electrode adsorption bowl. The air pump 21 is connected to the three-way joint through the air hose, and is connected to the shunt and the pressure detection module 22 through the air hose and the three-way joint. No special limitation is made herein for the specific type and implementation manner of the air hose for this application. Considering that the control of the suction force of the air pump 21 generally needs to be achieved by adjusting the power of the air pump 21, a power control circuit is additionally provided between the control module 3 and the air pump 21. The control module 3 issues a corresponding power control signal to the power control circuit, and realizes the adjustment of the suction force of the air pump 21 by controlling the power control circuit. The control module 3 can also realize the control of the suction force of the air pump 21 through other means, and no special limitation is made herein for this application, and it is not limited to the power control method proposed in this embodiment.

[0056] The utility model provides an electrostimulation intensity and negative pressure linkage control system, which includes an electrostimulation signal generation module, a current detection module 12, an air pump 21, a barometric pressure detection module 22, and a control module 3. The electrostimulation signal generation module, the current detection module 12, and the control module 3 form a closed-loop control circuit for generating electrostimulation signals. The air pump 21, the barometric pressure detection module 22, and the control module 3 form a closed-loop control circuit for the pressure inside the suction cup of the target electrode 4. The control module 3 can flexibly adjust the intensity of the electrostimulation signal and the negative pressure inside the suction cup of the target electrode 4 according to the treatment requirements, thereby avoiding skin problems caused by a constant negative pressure value. During the treatment process, the negative pressure value inside the electrode suction cup can also change with the change of the stimulation current intensity of the electrostimulation signal under the action of the control module 3. It can not only play the role of negative pressure massage but also produce an output effect in which the negative pressure cooperates with the electrostimulation and is interrelated, which can accelerate the muscle blood circulation of the rehabilitation patient, play the role of enhancing analgesia and eliminating stimulation fatigue, and improve the user experience.

[0057] Based on the above embodiments: Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of another electrostimulation therapeutic apparatus provided by the utility model; Please refer to Figure 4 , Figure 4 which is a schematic diagram of an electrode switching method provided by the utility model; Please refer to Figure 5 , Figure 5 which is a schematic structural diagram of an electrostimulation signal generation module provided by the utility model; Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of a roaming switching circuit provided by the utility model.

[0058] As an optional embodiment, the electrostimulation signal generation module includes:

[0059] an analog-to-digital conversion module, whose input end is connected to the output end of the control module 3, and is used to convert the output signal of the control module 3 into an intermediate-frequency electrostimulation signal;

[0060] a filtering module, whose input end is connected to the output end of the analog-to-digital conversion module;

[0061] a power amplification module, whose input end is connected to the output end of the filtering module, the first output end is used as the first output end of the electrostimulation signal generation module, and the second output end is used as the second output end of the electrostimulation signal generation module, and is used to amplify the power of the electrostimulation signal.

[0062] It is not difficult to understand that the electrical stimulation signal generation module can specifically convert the digital control signal output by the control module 3 into an electrical stimulation signal output by the electrode through a signal conditioning and amplification circuit including an analog-to-digital conversion module, a filtering module, and a power amplification module, thereby realizing the generation process of the electrical stimulation signal. The analog-to-digital conversion module can first convert the digital control signal output by the control module 3 into an analog voltage signal or current signal, realizing the modulation function of the intermediate-frequency electrical stimulation signal, so that the control module 3 can control the D / A (analog-to-digital) conversion module through digital quantity to realize the intermediate-frequency electrical stimulation signal modulation, making the signal have the output result of low-frequency modulation of intermediate frequency. The converted electrical signal is then filtered by the filtering module. For the intermediate-frequency electrical stimulation signal (1KHz - 15KHz), the filtering module generally needs to be implemented by a band-pass filter circuit, and the signals below 1KHz and above 15KHz need to be filtered out. The power amplification module mainly realizes the amplification of voltage or current of the filtered signal, generally mainly current amplification, and the amplification factor can also be adjusted separately by the control module 3. The specific types and implementation methods of the analog-to-digital conversion module, the filtering module, and the power amplification module are not particularly limited in this application and can be set and adjusted according to the specific situation of the electrical stimulation signal.

[0063] Specifically, the signal conditioning and amplification circuit including the analog-to-digital conversion module, the filtering module, and the power amplification module can effectively realize the function of the electrical stimulation signal generation module, enabling the control module 3 to generate the intermediate-frequency electrical stimulation signal through digital quantity. The specific working parameters of the power amplification module and the filtering module can also be flexibly adjusted according to the actual application situation to ensure that the target electrode 4 can obtain accurate and effective electrical stimulation signals.

[0064] As an optional embodiment, the electrical stimulation signal generation module further includes:

[0065] An absorption module, the first input end is connected to the first output end of the power amplification module, the second input end is connected to the second output end of the power amplification module, the first output end is used as the first output end of the electrical stimulation signal generation module, and the second output end is used as the second output end of the electrical stimulation signal generation module, for eliminating electromagnetic interference signals.

[0066] It is not difficult to understand that considering that the power amplification process may cause abnormal electromagnetic interference signals, an absorption circuit can be further added in the electrical stimulation signal generation module to eliminate the electromagnetic interference signals generated by power amplification, so that the entire system is protected from its own electromagnetic interference and the interference of this device to other electromagnetic devices. Therefore, the absorption circuit generally needs to be implemented by an EMI (Electromagnetic Interference) absorption circuit. The specific implementation method and circuit structure of the absorption circuit are not particularly limited in this application.

[0067] Specifically, an absorption circuit can also be added to absorb interference signals in the circuit, further ensuring the accuracy and reliability of the finally output electrical stimulation signal. The entire electrical stimulation signal generation module has a simple structure and is easy to implement, which is conducive to the simple implementation of the entire electrical stimulation intensity and negative pressure linkage control system.

[0068] As an alternative embodiment, the electrical stimulation signal generation module further includes:

[0069] A transformer, where the first end of the primary winding is connected to the first output end of the absorption module, the second end of the primary winding is connected to the second output end of the absorption module, the first end of the secondary winding serves as the first output end of the electrical stimulation signal generation module, and the second end of the secondary winding serves as the second output end of the electrical stimulation signal generation module.

[0070] It is not difficult to understand that in some application scenarios, the voltage of the electrical stimulation signal also needs to reach a certain value to meet the treatment requirements. Therefore, the intermediate-frequency electrical stimulation signal passing through the signal conditioning and amplification circuit can be further transmitted to the transformer for step-up amplification, that is, the process of voltage amplification, so as to achieve the voltage gain of the electrical stimulation signal. The electrical stimulation signal passing through the power amplification module is further power-amplified by the transformer. At this time, the current transformer can be directly installed on the secondary side of the transformer to detect the electrode output current, and the detection result is transmitted to the control module 3 as a feedback signal. The specific type, working parameters, and specific implementation manner of the transformer are not particularly limited in this application and can be set and adjusted according to actual application requirements.

[0071] Specifically, the power amplification of the electrical stimulation signal can also be further achieved by adding a transformer, ensuring that the voltage and power of the electrical stimulation signal can meet the treatment requirements and guaranteeing the final treatment effect; the entire electrical stimulation signal generation module has a simple structure and is easy to implement, which is conducive to the simple implementation of the entire electrical stimulation intensity and negative pressure linkage control system.

[0072] As an alternative embodiment, it further includes:

[0073] A shunt, with the input end connected to the output end of the air pump 21, the first output end connected to the suction cup of the first electrode of the target electrode 4, and the second output end connected to the suction cup of the second electrode of the target electrode 4.

[0074] It is not difficult to understand that, considering that the target electrode 4 refers to a pair of electrodes, including a first electrode and a second electrode, when the air pump 21 is connected to the target electrode 4, the output end of the air pump 21 can be connected to the first electrode and the second electrode respectively through a flow divider, and the flow divider divides the gas path output by the air pump 21 into two paths, thereby realizing the simultaneous control of the adsorption pressure of a pair of electrodes in the target electrode 4 by the air pump 21. The specific material, shape, type and other specific implementation methods of the flow divider are not particularly limited in this application, and can be set and adjusted according to actual application requirements.

[0075] Specifically, in order to ensure that the air pump 21 can uniformly control the adsorption pressure of a pair of electrodes in the target electrode 4, a diverter can be added to the air circuit to divide the air circuit into two circuits, thereby realizing unified control of the two electrodes by a single air pump 21, reducing the setting of the air pump 21, reducing the cost and volume, and facilitating the simple implementation of the entire electrical stimulation intensity and negative pressure linkage control system.

[0076] As an optional embodiment, it also includes:

[0077] The three-way connector has a first interface connected to the output end of the air pump 21 , a second interface connected to the input end of the diverter, and a third interface connected to the input end of the air pressure detection module 22 .

[0078] It is not difficult to understand that the control module 3 realizes the power regulation of the air pump 21 by controlling the power control circuit, and the air pump 21 realizes the negative pressure suction of the target electrode 4 by connecting the diverter through the air line hose. When the power of the air pump 21 changes, its suction force on the electrode will also change accordingly, thereby realizing the adjustment process of the adsorption pressure of the target electrode 4. Considering that the air pump 21 needs to use the diverter to realize the negative pressure suction process of the two electrodes in the target electrode 4, and the air pressure detection module 22 also needs to detect the current adsorption pressure of the target electrode 4, the air pressure detection module 22, the air pump 21 and the diverter can be connected to each other in the air line by setting a three-way joint. The air pressure detection module 22 detects the pressure value in the adsorption electrode suction cup in real time through the three-way joint; the air pump 21 sucks the target electrode 4 through the three-way joint, the diverter and the air line hose. The specific type and implementation method of the three-way joint are not particularly limited in this application.

[0079] Specifically, considering that the gas circuit needs to be connected through pipelines, when multiple devices are connected in the gas circuit, it is necessary to set up an air pipe joint to realize the connection between the gas circuit and each device to ensure that the gas can flow smoothly; the air pipe joint has good sealing performance, which can effectively prevent gas leakage and ensure the accurate and effective negative pressure suction process of the air pump 21 on the target electrode 4.

[0080] As an alternative embodiment, when the electrostimulation therapeutic apparatus includes at least two groups of target electrodes 4, the electrostimulation intensity and negative pressure linkage control system further includes:

[0081] A roaming switching circuit 31, with its first input terminal connected to the first output terminal of the electrostimulation signal generation module, its second input terminal connected to the second electrodes of each group of target electrodes 4, its first output terminal connected to the first electrodes of each group of target electrodes 4, and its second output terminal connected to the second output terminal of the electrostimulation signal generation module, for switching the inflow electrode and / or outflow electrode of the electrostimulation signal output by the electrostimulation signal generation module.

[0082] It is not difficult to understand that when the electrostimulation therapeutic apparatus includes at least two groups of target electrodes 4, the electrode conduction state switching cooperation between each group of target electrodes 4 can also be achieved with the help of the roaming switching circuit 31. For example, Figure 3 As shown, taking two groups of target electrodes 4 as an example, at this time, the system includes the first electrode O1, the second electrode of the first group of target electrodes, the first electrode O2, and the second electrode of the second group of target electrodes. Under normal circumstances, the electrostimulation intensity and negative pressure linkage control system corresponding to the first group of target electrodes 4 will output a first electrostimulation signal to the first electrode O1 of the first group of target electrodes. The first electrostimulation signal flows into the human body from the first electrode O1 of the first group of target electrodes, and then flows out from the second electrode OUT1- of the first group of target electrodes and returns to the electrostimulation intensity and negative pressure linkage control system, forming a treatment loop; the electrostimulation intensity and negative pressure linkage control system corresponding to the second group of target electrodes 4 will output a second electrostimulation signal to the first electrode O2 of the second group of target electrodes. The second electrostimulation signal flows into the human body from the first electrode O2 of the second group of target electrodes, and then flows out from the second electrode OUT2- of the second group of target electrodes and returns to the electrostimulation intensity and negative pressure linkage control system, forming another treatment loop. After adding the roaming switching circuit 31, the roaming switching circuit 31 plays a role, and the treatment loop can be adjusted by adjusting the inflow electrode and / or outflow electrode corresponding to the electrostimulation signal. For example, Figure 4 As shown, it can be controlled that the first electrostimulation signal flows into the human body from the first electrode O1 of the first group of target electrodes, and then flows out from the second electrode OUT2- of the second group of target electrodes and returns to the electrostimulation intensity and negative pressure linkage control system, forming a treatment loop; control the second electrostimulation signal to flow into the human body from the first electrode O2 of the second group of target electrodes, and then flow out from the second electrode OUT1- of the first group of target electrodes and return to the electrostimulation intensity and negative pressure linkage control system, forming another treatment loop. Thus, the switching of the treatment loop is realized, and the treatment range is expanded. When multiple groups of target electrodes 4 are set. There are multiple choices for the combination of electrode switching methods. The present application does not make special limitations here, and the treatment range can be determined according to the actual treatment needs, so as to determine the specific method of electrode switching.

[0083] It should be noted that the roaming switching circuit 31 can be independently controlled by the control module 3 to achieve the switching of the electrode conduction state. At this time, the three control processes of the electrical stimulation output intensity, the negative pressure adsorption value, and the electrode conduction state switching can cooperate with each other to achieve a compound treatment effect. The roaming electrode switching will cause the situation of electrode crossover, which can effectively expand the treatment range. The specific type and implementation manner of the roaming switching circuit 31 are not particularly limited in this application and can be set according to the actual roaming requirements.

[0084] The present utility model not only provides an electrical stimulation generation system and method for realizing that the current intensity changes following the negative pressure magnitude, so that the negative pressure value in the electrode suction cup will change with the change of the stimulation current intensity during the treatment process, which can not only play the role of negative pressure massage, but also produce the effect of negative pressure cooperating with the associated output of electrical stimulation. It can also make the electrical stimulation intensity output, the negative pressure value change, and the electrode switching be interrelated in the interference current or roaming current mode, accelerate the muscle blood circulation of the rehabilitation patient, and play the role of enhancing analgesia and eliminating stimulation fatigue.

[0085] As an optional embodiment, if the electrical stimulation therapeutic apparatus includes two groups of target electrodes 4, the roaming switching circuit 31 includes:

[0086] A relay coil K0, with the first end connected to the power supply and the second end connected to the output end of the control module 3, for being energized or de-energized based on the control of the control module 3;

[0087] A first relay contact K11, with the moving end connected to the first electrode O1 of the first group of target electrodes, the first fixed end connected to the second electrode OUT1- of the first group of target electrodes, and the second fixed end connected to the second electrode OUT2- of the second group of target electrodes; the electrical stimulation signal flows into the first electrode of the target electrode and flows out from the corresponding second electrode of the target electrode;

[0088] A second relay contact K12, with the moving end connected to the first electrode O2 of the second group of target electrodes, the first fixed end connected to the second electrode OUT2- of the second group of target electrodes, and the second fixed end connected to the second electrode OUT1- of the first group of target electrodes; the operating states of the first relay contact K11 and the second relay contact K12 are the same.

[0089] It is not difficult to understand that in order to implement the roaming (crossing) function between two sets of electrodes, the present application designs an electrode switching circuit including a relay coil K0, a first relay contact K11, and a second relay contact K12. The electrode switching circuit is implemented by a single-pole double-throw relay, and the two relay contacts will act simultaneously. When the pins 1 and 8 at both ends of the relay coil K0 are powered on under the control of the control module 3, the moving end pin 3 of the first relay contact K11 is connected to the first fixed end pin 2, and the moving end pin 6 of the second relay contact K12 is connected to the first fixed end pin 7. The electrical stimulation signal will flow in from the first electrode O1 of the first group of target electrodes connected to the moving end, flow out from the second electrode OUT1- of the first group of target electrodes, and flow in from the first electrode O2 of the second group of target electrodes connected to the moving end, and flow out from the second electrode OUT2- of the second group of target electrodes, realizing as shown in Figure 4 the electrode state shown on the left, and two sets of parallel electrodes appear; when the pins 1 and 8 at both ends of the relay coil K0 are powered off under the control of the control module 3, the moving end pin 3 of the first relay contact K11 is connected to the second fixed end pin 4, and the moving end pin 5 of the first relay contact K11 is connected to the second fixed end pin 6. The electrical stimulation signal will flow in from the first electrode O1 of the first group of target electrodes connected to the moving end, flow out from the second electrode OUT2- of the second group of target electrodes, and flow in from the first electrode O2 of the second group of target electrodes connected to the moving end, and flow out from the second electrode OUT1- of the first group of target electrodes, realizing as shown in Figure 4 the electrode state shown on the right, and the crossing between electrodes appears.

[0090] Specifically, through the single-pole double-throw relay, the effective switching of the electrodes can be realized, and the second electrode connected to the first electrode O1 of the first group of target electrodes and the first electrode O2 of the second group of target electrodes is switched through the action of the relay contact, so as to realize the adjustment of the treatment circuit; the whole circuit structure is simple and easy to implement.

[0091] As an optional embodiment, the roaming switching circuit 31 further includes:

[0092] A power supply resistor R0, the first end of which is respectively connected to the power supply and the first end of the relay coil K0;

[0093] A prompt module D0, the first end of which is connected to the second end of the power supply resistor R0, and the second end of which is connected to the second end of the relay coil K0, and is used to perform corresponding prompt operations based on the power-on and power-off conditions of the relay coil K0.

[0094] It can be understood that, in order to facilitate the operator to accurately determine the inflow electrode and the outflow electrode of the current electrical stimulation signal and avoid confusion during the operation process, a prompt module D0 can be further added and set in the roaming switching circuit 31. The prompt module D0 is connected to the power supply through a power supply resistor R0. When the relay coil K0 is powered on, the prompt module D0 also works accordingly to prompt that the current electrodes are in a cross working state; when the relay coil K0 is powered off, the prompt module D0 does not work. The specific types and implementation methods of the power supply, the prompt module D0, and the power supply resistor R0 are not particularly limited in this application. The prompt module D0 can be implemented by means of a light-emitting diode D1, etc. The power supply resistor R0 mainly plays a role in current limiting and voltage division, and can be set according to the specific settings of the power supply and the prompt module D0. As Figure 6 shown, the power supply is realized by a 5V power supply.

[0095] Furthermore, in order to ensure the accurate control of the control module 3 over the roaming switching circuit 31, a diode D1 connected in parallel can be further added and set between the output end of the control module 3 and the power supply. The anode of the diode D1 is connected to the output end of the control module 3, and the cathode is connected to the power supply, to avoid the power supply from flowing back into the control module 3, ensure the accurate control of the control module 3 over the roaming switching circuit 31, and further protect the circuit. The specific type and implementation method of the diode D1 are not particularly limited in this application.

[0096] Specifically, components such as the prompt module D0, the power supply resistor R0, and the diode D1 can be further added and set in the roaming switching circuit 31 according to application requirements, to improve the accuracy and reliability of the control process of the control module 3 over the roaming switching circuit 31, protect the circuit, and ensure the normal operation of the roaming switching circuit 31.
