Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a circuit for an electrical stimulation and electric field treatment device, as shown in fig. 1, including a direct current unit 61, an alternating current/direct current unit 63, a feedback unit 64, and a controller 62. The direct current unit 61 is connected with the alternating current/direct current unit 63 and is used for providing reference voltage for the alternating current/direct current unit 63; the feedback unit 64 is respectively connected with the ac/dc unit 63 and the controller 62, and the feedback unit 64 is used for feeding back the electric signal of the ac/dc unit 63 to the controller 62; the controller 62 is configured to adjust the reference voltage and the driving signal of the ac/dc unit based on the operating mode of the circuit and the electrical signal.

Specifically, the dc unit 61 not only provides a reference voltage for the ac/dc unit 63, but also provides a dc voltage for other electric circuits of the circuit. The DC unit 61 is a DC-DC conversion unit, and is configured to convert an input battery voltage into a DC voltage of at least one class, where the converted DC voltage is used to provide a reference voltage and voltages required by other circuits. For example, the circuit includes a rechargeable power supply connected to the DC-DC conversion unit to supply a direct current power to the DC-DC conversion unit.

The AC/DC unit 63 is a DC-AC circuit, and may be designed by an inverter circuit such as a full bridge circuit or a half bridge circuit, and the specific structure thereof is not limited herein. The ac/dc unit 63 is connected to a controller and the electrodes, wherein the controller is configured to provide a driving signal for the ac/dc unit 63, and when the circuit operates in the first mode, the controller is further configured to adjust a reference voltage setting value of the ac/dc unit 63.

It should be noted that the first mode for electrical stimulation is a low current mode, and the second mode for electric field therapy is a high current mode. Specifically, various electrical stimulation functions are built into the controller of the circuit, each corresponding to a respective mode, for example, function a and function B correspond to a first mode, and function C corresponds to a second mode. Optionally, in the first mode and/or the second mode, the first gear, the second gear and the like are also classified according to different intensities. The number of the gears divided by each mode and the relationship between the gears can be set according to actual requirements, and the setting is not limited herein. The first mode and the second mode provide different stimulation current ranges, and the first mode provides a smaller stimulation current range, so the stimulation current range can also be called as a low current mode; the second mode provides a stimulation current with a large current range and may therefore also be referred to as a high current mode.

Under the low current mode, because the stimulation current is less, therefore the controller adjusts the reference value through comparing first, adjusts the reference voltage to the alternating current-direct current unit with it cooperation for the stimulation current of alternating current-direct current unit output can satisfy the demand that the user set up. In a large-current mode, the amplitude of the pulse current flowing through the electrode is controlled in a closed loop mode by adjusting the driving signal of the alternating current-direct current unit based on the magnitude of the electric signal.

The feedback unit 64 is used for feeding back the electrical signal of the ac/dc unit 63 to the controller 62, wherein the electrical signal may be the stimulation current of the ac/dc unit 63, or the like. For example, a current detection element may be provided near the electrode, and the detection result of the current detection element may be fed back to the controller 62; or, different feedback units 64 are provided for different operation modes, specifically, for the first mode, the comparison of the stimulation currents may be performed by means of an operational amplifier branch; for the second mode, the current sensing element may be used to collect the current and send the collected current to the controller 62 for comparison. A detailed description will be made below regarding a specific circuit structure of the feedback unit 64.

The controller 62 may be any device having a data processing function, such as a single chip, an FPGA, or the like. The selection of the specific type of the controller 62 is made according to actual requirements, and is not limited herein.

The circuit for the electrical stimulation and electric field therapy device provided by this embodiment adjusts different objects according to different working modes of the electrical stimulation and electric field therapy device, that is, adjusts the magnitude of the reference voltage and the driving signal respectively for different working modes, so that the controller can adjust the corresponding control strategy for the working modes, wherein the adjustment for the reference voltage is suitable for the working mode with small current, and the adjustment for the driving signal is suitable for the working mode with large current, thereby expanding the application scenarios of the electrical stimulation and electric field therapy device.

In an optional implementation manner of this embodiment, the feedback unit includes a first feedback module and a second feedback module. The first feedback module corresponds to the first mode, and the second feedback module corresponds to the second mode. When the current working mode of the electrical stimulation and electric field treatment device is determined, the controller 62 controls the corresponding pins to work and receives the electrical signals fed back by the first feedback module or the second feedback module corresponding to the feedback unit.

For example, a first feedback module is connected to a first pin of the controller 62 and a second feedback module is connected to a second pin of the controller 62. When the controller 62 determines that the current operating mode of the electrical stimulation and electric field treatment device is the first mode, the controller 62 controls the first pin to operate and the second pin to not operate, and receives the electrical signal fed back by the first feedback module. At this time, the second feedback module may also collect the electrical signal, but the controller 62 does not adopt the result collected by the second feedback module; alternatively, the controller 62 directly controls the second feedback module to be inactive and only the first feedback module to be active.

When the controller 62 determines that the current operating mode of the electrical stimulation and electric field treatment device is the second mode, the controller 62 controls the second pin to operate and the first pin to operate, and receives the electrical signal fed back by the second feedback module. At this time, the first feedback module may also perform electric signal acquisition, but the controller 62 does not adopt the result acquired by the first feedback module; alternatively, the controller 62 directly controls the first feedback module to be inactive and only the second feedback module to be active.

Specifically, the first feedback module is provided with an electric signal branch and an operational amplifier branch, the electric signal branch is connected with the alternating current-direct current unit, and the operational amplifier branch is respectively connected with the electric signal branch and the controller. As shown in fig. 2, the electrical signal branch 97 is used for transmitting the electrical signal of the ac/dc unit to the operational amplifier branch 90. The electrical signal branch 97 performs electrical signal acquisition by using a resistor voltage division method, and may also perform electrical signal acquisition by using other methods.

The operational amplifier branch 90 is used for connecting the electrical signal branch 97 with the controller 22, and the operational amplifier branch 90 is used for comparing the electrical signal collected by the electrical signal branch 97 with an electrical signal standard value preset in the controller 22 based on the current working mode, so as to realize constant current control. The actual current in the circuit is sampled by resistor 19 and fed back to controller 22 via isolation 20, regulated 25 and filtered 33. The controller 22 adjusts the reference voltage of the ac-dc unit based on the actual current sample feedback. In the first mode, the driving signal output by the controller 22 does not change with the change of the electric signal, and the driving signal is output according to the setting parameter of the first mode. That is, the current amplitude of the basic pulse is determined by the positive and negative input terminals of the operational amplifier 21, and the duration of the positive and negative pulses of the basic pulse is determined by the controller 22 according to the setting parameters of the first mode.

Further, the circuit shown in fig. 2 can provide a basic pulse waveform, and can also realize low-frequency modulation of the basic waveform, and realize various waveform combinations. Wherein the fundamental frequency of the fundamental waveform may be an intermediate frequency or a high frequency. The local amplification of the intermediate frequency or high frequency waveform is realized by carrying out low frequency modulation on the intermediate frequency or high frequency waveform. For example, in the circuit shown in fig. 2, in the first mode, the amplitude of the output pulse waveform can be adjusted by adjusting the magnitude of the first comparison reference value output from the DA terminal of the controller 22; by adjusting the duration of the output pulse from the controller 22, the time to output the pulse waveform can be adjusted. In the second mode, the duty ratio of the driving pulse is adjusted according to the result of the current loop operation 33, so that the amplitude of the output pulse waveform can be adjusted, and the duration of the output pulse of the controller 22, that is, the time of the output pulse waveform, can be adjusted. The low-frequency modulation is carried out on the basic waveforms, so that the low-frequency modulation of various basic waveforms such as square wave alternating current pulses can be realized.

The second feedback module is provided with a current detection piece and is used for measuring an electric signal of the alternating current-direct current unit and feeding back the electric signal to the controller. As shown in fig. 2, two electrodes, electrode 1 and electrode 2, are connected to the ac/dc unit, and a current detector may be disposed near the two electrodes to detect the stimulation current. The current detection element may be a hall element, a current transformer, or the like, and is not limited herein, and may be selected according to actual requirements. As shown in fig. 2, after the current detection element in the second feedback module collects the electrical signals of the ac/dc unit, the electrical signals are processed by the isolation 30 and the rectification filter 32 and then fed back to the controller. The controller performs closed-loop operation on the electric signals inside and outputs two paths of driving signals with dead zones.

The controller is internally provided with an electric signal standard value corresponding to the setting parameter of the second mode, the second feedback module feeds back the collected electric signal to the controller, the controller compares the electric signal with the electric signal standard value, closed-loop calculation is carried out according to the comparison result, and the driving signal is adjusted according to the result. Specifically, in the second mode, the reference voltage of the ac/dc unit is kept constant, which is determined according to the setting parameters of the second mode. And the controller controls and adjusts the driving signal according to the closed-loop operation result, performs current closed-loop operation based on the electric signal acquired by the second feedback unit and the current signal standard value determined by the setting parameter of the second mode, and adjusts the driving signal according to the operation result.

Two different feedback modules are adopted to correspond to different working modes, pulse constant current control is carried out in a mode of an operational amplifier branch circuit aiming at a small current mode, then a reference voltage matched with a first comparison reference value, namely the amplitude of basic pulse current is determined, the size of the reference voltage is adjusted, the matching degree of the reference voltage and the stimulation current is improved, and therefore the overall efficiency of the electrical stimulation and electric field treatment equipment is improved.

As an alternative to this embodiment, as shown in fig. 2, the electrical signal branch 97 includes a first controllable switch 18 and a resistor 19. The first controllable switch is respectively connected with the alternating current-direct current unit and the operational amplifier branch, the first end of the resistor is connected with the first controllable switch, the second end of the resistor is grounded, and the first end of the resistor is connected with the operational amplifier branch. The first working mode is selected and the feedback of the electric signal is realized through the form of the first controllable switch and the resistor, the current control precision is higher in low current, and the circuit structure is simplified.

When the electrical stimulation and electric field treatment device works in the first mode, as shown in fig. 2, the controller 22 controls the first controllable switch 18 to be turned on, the voltage division and sampling are performed through the resistor 19, the electrical signal of the resistor is fed back to the operational amplifier branch 90, and after the operational amplifier branch 90 performs the isolation processing on the electrical signal, the processed electrical signal is compared with the standard value of the electrical signal output by the DA pin of the controller 22, so as to realize the constant current control of the basic pulse. The voltage sampling result of the resistor 19 is fed back to an AD pin of a controller 22 after being isolated by 20, stabilized by 25 and filtered by 23. After receiving the actual current sampling result, the controller 22 adjusts the reference voltage to correspond thereto based on the result, ensuring that a desired actual current value can be output. In the working process of the equipment, the judgment is carried out in real time according to the actual current sampling result, and if the current output capacity is not enough, the value of the reference voltage is increased; if the reference voltage is greater than the corresponding actual current value demand, the reference voltage is decreased.

As shown in fig. 2, the operational amplifier branch 90 includes an operational amplifier 21, an isolation 20, a voltage regulator 25, and a filter 23. Specifically, the anode of the operational amplifier 21 is connected to a DA pin of the controller 22, and the DA pin is used for outputting a first comparison reference value; the negative pole of the operational amplifier 21 is connected to the current sample 19 via an isolation 20 for constant current control of the basic pulses. When the first controllable switch 18 is turned on and the switching tube 07 is turned off, the device operates in the low-current operating mode. When the first controllable switch 18 is turned off and the switching tube 07 is turned on, the high-current operating mode is performed.

In some optional implementations of this embodiment, the first feedback module further includes a second controllable switch, and the second controllable switch is connected in parallel with the electrical signal branch. The controller is used for controlling the action of the second controllable switch based on the working mode of the electric stimulation and electric field treatment device. The working state of the electric signal branch circuit is controlled through the second available switch, so that the alternating current and direct current unit can be normally grounded.

As shown in fig. 2, when the electrical stimulation and electric field treatment device is in the first mode, the controller 22 controls the second controllable switch 07 to be turned off, and the electrical signal branch circuit works to collect the electrical signal of the ac/dc unit and feed back the electrical signal to the operational amplifier branch circuit 90. When the electrostimulation and electric field treatment device is in the second mode, the controller 22 controls the second controllable switch 07 to be on, the electrical signal branch is short-circuited, and the ac-dc unit is grounded 26.

In some optional implementations of this embodiment, the dc unit includes a power module and a voltage adjustment module. The input end of the voltage adjusting module is connected with the power supply module, and the output end of the voltage adjusting module is connected with the alternating current-direct current unit and used for providing reference voltage; and the control end of the voltage adjusting module is connected with the controller. The reference voltage is adjusted through the voltage adjusting module, and the adjusting mode of the reference voltage is simplified.

The specific working principle of the direct current unit is as follows: the power supply module is used for outputting at least one grade of direct current voltage, and the direct current voltage is used for providing working power supply for other power utilization circuits in the electric stimulation and electric field treatment equipment. One output voltage in the direct current unit is connected with a voltage adjusting module, the voltage adjusting module adjusts the output voltage of the voltage adjusting module under the control of the controller, and the output voltage of the voltage adjusting module is the reference voltage of the alternating current/direct current unit. The voltage adjusting module can be a variable resistor, a digital potentiometer, or the like.

In some optional implementations of this embodiment, the ac/dc unit includes a driving module, an isolating module, and a controllable module. The driving module is respectively connected with a first end and a second end of the controller, the first end corresponds to the first mode, and the second end corresponds to the second mode. Of course, the first end and the second end may be the same or different, and are specifically set according to actual requirements.

The isolation module is used for connecting the driving module and the corresponding controllable module and is used for realizing the isolation of the driving module and the controllable module. The isolation module may be isolated by photoelectric isolation or other isolation methods, which are not limited herein. Further, in the case where the 1VB voltage is low, no isolation module is required.

The controllable module is respectively connected with the direct current unit, the electrode and the feedback unit, wherein the direct current unit is used for providing reference voltage for the controllable module; the electrodes are respectively connected with the target object and used for applying electric stimulation to the target object; the feedback unit is used for feeding back the electric signal of the controllable module to the controller.

As mentioned above, the ac/dc unit may be a full bridge circuit, or a half bridge circuit, etc. Taking a full-bridge circuit as an example, as shown in fig. 2, the driving module includes a left driver 27 and a right driver 28, and the left driver 27 and the right driver 28 respectively include two drivers, each corresponding to one of the isolations. In fig. 2, the ac/dc unit includes a controllable unit 29 in addition to the driving module, and the controllable unit 29 includes a switching tube 1-a switching tube 4, two electrodes, and the like.

As shown in fig. 2, the voltage of the dc unit is determined by the load of the target object and the pulse intensity, and in order to ensure that a sufficiently large current is applied to the target object, a boost circuit of up to about one hundred volts is required to be designed even in a large current application scenario. The Boost circuit is a dc Boost circuit, and generally comprises a switching device, a diode, an inductor, and a capacitor.

The alternating current-direct current unit adopts a full-bridge circuit design, is used for outputting bipolar waveforms with completely symmetrical positive and negative, is applied to the electrode 1 and the electrode 2 shown in fig. 2, and acts on a target object. When the switching tubes 2, 3, 4 and 5 are all off, no current enters the electrodes; when the switch tubes 2 and 3 are closed and the switch tubes 4 and 5 are opened, the current flowing through the human body load is in the direction from the electrode 1 to the electrode 2, namely 11 → 10; when the switching tubes 4 and 5 are closed and the switching tubes 2 and 3 are opened, the current flowing through the target object flows from the electrode 2 to the electrode 1, i.e., 10 → 11. Based on this, there is a bipolar change in the current applied to the target object through the electrodes. The switching tubes 2 and 5 or 3 and 4 on the same bridge arm cannot be closed at the same time, and a power supply to ground short-circuit protection circuit is designed. The AC/DC unit is driven and controlled by switching tubes 2, 5, 4 and 3 through

optical coupling isolation

12, 15, 13 and 14 by driving signals 6, 7, 8 and 9 sent by a controller. The driving signal and the bridge arm have dead zones, the dead zone time is determined according to the relevant characteristics of the switching tube, and the driving design simultaneously meets the floating characteristic of the full bridge circuit.

The wireless communication device 06 may be a remote control, or other mobile terminal, etc. The working mode is set in a wireless communication mode, the setting mode is simple, and remote control can be realized.

As shown in fig. 3, the working mode of the electric stimulation and electric field treatment device and the setting of the mode parameters are set and adjusted by the wireless communication device 07 through a wireless communication mode. The electric stimulation and electric field treatment device can be charged by a built-in battery, and is compact in structure and portable to wear.

The electrical stimulation and electric field treatment device can be operated in two modes, a first mode (low current mode) and a second mode (high current mode). As shown in fig. 2, in the first mode, after the controller determines the driving signal based on the mode parameter, the controller outputs a corresponding driving signal according to the control requirement, and the driving signal controls the duration of the pulse and is not affected by the electric signal of the ac/dc unit. Meanwhile, the controller adjusts the reference voltage of the alternating current and direct current unit based on the electric signal of the alternating current and direct current unit so as to meet the control requirement.

In the second mode, after the controller determines the reference voltage of the ac/dc unit based on the mode parameter, the reference voltage is maintained during the subsequent control. Meanwhile, the controller adjusts the driving signals of the alternating current and direct current units based on the electric signals of the alternating current and direct current units so as to meet the control requirements. For example, as shown in fig. 2, the isolation 16 is transformer isolation, the controller is designed to output high frequency modulation pulses, the full bridge circuit is controlled after the isolation is performed by the driving 27 and 28, the output is applied to a target object between the

electrodes

11 and 10 after passing through the isolation 16 and the filtering 17, and the design of the filtering circuit is related to the steady-state accuracy of the pulse current. In this mode, the reference voltage of the alternating current-direct current unit does not need to be adjusted according to parameter setting, and the efficiency is higher. In the second mode, the feedback current is sampled, sent to the controller 22 through the isolation 30 and the rectifying filter 32 in fig. 2, and a closed-loop control algorithm is used in the controller 22 to obtain a suitable driving waveform 35, and sent to the left drive 27 and the right drive 28 from the port 99 for real-time control, so as to meet the requirement of constant current control. And various basic alternating current waveforms with higher precision can be output in the two modes, and various waveform combinations after low-frequency modulation are output.

In accordance with an embodiment of the present invention, there is provided a control method embodiment for an electrical stimulation and field therapy device, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein. For the specific structure of the electrical stimulation and electric field treatment device, reference may be made to the above description.

In this embodiment, a control method for an electrical stimulation and electric field therapy device is provided, which can be used in a controller of the electrical stimulation and electric field therapy device, and details of the structure of the electrical stimulation and electric field therapy device are described above and are not described herein again. Fig. 4 is a flowchart of a control method for an electrical stimulation and electric field treatment device according to an embodiment of the present invention, as shown in fig. 4, the flowchart including the steps of:

and S11, acquiring the setting result of the current control parameters of the electric stimulation and electric field treatment device.

Wherein the current control parameters comprise a current operating mode and configuration parameters, the current operating mode comprising a first mode for electrical stimulation or a second mode for electric field therapy.

The current operation mode includes the first mode and the second mode described above, i.e., the low current mode for electrical stimulation and the high current mode for electric field therapy. The configuration parameters are mode parameters in each mode, such as pulse intensity, current range, and the like. In each working mode, a plurality of intensities are corresponding for selection, and after a certain intensity is determined, the corresponding configuration parameters are correspondingly determined.

The acquisition of the current control parameters may be obtained by the interaction of the electrical stimulation and electric field therapy device with the user, or by the remote communication of the electrical stimulation and electric field therapy device with an external device, etc., and the acquisition mode is not limited in any way.

In some optional implementations of this embodiment, the step S11 may include:

(1) mode selection results of the electrical stimulation and electric field therapy device are obtained to determine a current operating mode.

(2) And acquiring a setting result of the configuration parameters in the current working mode to determine the configuration parameters.

Modes of electrical stimulation and electric field therapy devices include, but are not limited to, muscle stimulation, transcranial stimulation, implant modes, or software updates, each mode corresponding to an operating mode. Once the mode of the electrical stimulation and electric field treatment device is determined, the current mode of operation of the electrical stimulation and electric field treatment device can be determined accordingly.

The electrical stimulation and electric field treatment equipment provides a parameter setting function, and configuration parameters can be determined by setting the configuration parameters on an external equipment or an interactive interface provided by the electrical stimulation and electric field treatment equipment.

And S12, acquiring the electric signal of the alternating current and direct current unit fed back by the feedback unit.

For the specific structure and connection mode of the feedback unit and the ac/dc unit, please refer to the above detailed description of the electrical stimulation and electric field therapy apparatus, which is not described herein again.

Similarly, for different current operating modes, the corresponding first feedback module or second feedback module is used for collecting the electric signals of the ac/dc unit, and feeding the collected electric signals back to the electronic device, i.e., the controller.

And S13, adjusting the reference voltage or the driving signal of the AC/DC unit in real time based on the current working mode, the configuration parameters and the electric signal.

As described above, when the current operating mode of the electrical stimulation and electric field treatment device is the first mode, the electronic device adjusts the reference voltage of the ac/dc unit in real time based on the configuration parameters and the electrical signal; when the current working mode of the electric stimulation and electric field treatment equipment is the second mode, the electronic equipment adjusts the driving signals of the alternating current and direct current units in real time based on the configuration parameters and the electric signals. Both adjustments are such that the desired constant current pulse is achieved, and the duration of the pulse, i.e. the positive and negative switching times of the basic pulse, is determined by the mode of operation.

Furthermore, in the first mode, the driving signal output by the electronic device does not change along with the change of the electric signal, the change of the electric signal is a reference voltage, and the change of the driving signal of the electronic device determines the duration of the positive and negative pulses; in the second mode, the driving signal output by the electronic device is changed along with the change of the electric signal, and the reference voltage is not changed.

Details about this step will be described later. The control method of the electrical stimulation and electric field treatment device provided by the embodiment adopts different control strategies according to different working modes, so that the control reliability is improved.

In some optional implementations of this embodiment, the control method may further include:

(1) detecting whether the control parameters of the electrical stimulation and electric field treatment device are updated.

(2) And when the control parameters are updated, determining the updated control parameters as the current control parameters.

The updating of the control parameters may occur during the electrical stimulation, and may be updated if the user wants to adjust the operating mode, or configure the parameters. The electronic equipment detects whether the control parameters are updated in real time, determines the updated control parameters as the current control parameters after detecting that the control parameters are updated, and controls the electrical stimulation and electric field treatment equipment by utilizing the updated control parameters in time.

The control accuracy is ensured by detecting the updating condition of the control parameters in real time and taking the latest control parameters as the current control parameters.

In the present embodiment, there is provided a control method for an electrical stimulation and electric field treatment device, which can be used in the controller for the electrical stimulation and electric field treatment device, where in the case that the current operation mode is the first mode, fig. 5 is a flowchart of the control method for the electrical stimulation and electric field treatment device according to the embodiment of the present invention, as shown in fig. 5, the flowchart includes the following steps:

and S21, acquiring the setting result of the current control parameters of the electric stimulation and electric field treatment equipment.

Please refer to S11 in fig. 4 for details, which are not described herein.

And S22, acquiring the electric signal fed back by the feedback unit.

Please refer to S12 in fig. 4, which is not repeated herein.

And S23, adjusting the reference voltage or the driving signal of the AC/DC unit based on the current working mode, the configuration parameters and the electric signal.

Specifically, S23 includes:

s231, determining an initial value of the reference voltage and a first comparison reference value based on the configuration parameters.

The configuration parameters may include a range of stimulation currents, and the initial value of the reference voltage is determined based on the range of stimulation currents. For example, in the first mode, the electrical stimulation and electric field therapy device provides the user with a choice of whether to soft start or direct start. If soft start is selected, the human body impedance is calculated using the minimum value of the stimulus current and the reference voltage applied at that time. Then the reference voltage is gradually increased based on the feedback electric signal until the magnitude of the reference voltage is matched with the stimulation current and the human body impedance; if the direct starting is selected, the reference voltage is calculated by utilizing the maximum values of the stimulation current and the human body impedance, and then the reference voltage is finely adjusted based on the feedback electric signal.

The first comparison reference value is determined based on the configuration parameters, for example, based on the type and intensity of the waveform.

And S232, outputting the first comparison reference value to an operational amplifier branch of the electrical stimulation and electric field treatment equipment.

The electronic device outputs the first comparison reference value to an operational amplifier branch of the electrical stimulation and electric field treatment device, which is used as a comparison reference of the operational amplifier.

S233, the comparison result of the operational amplifier branch is received.

Wherein the comparison result is determined based on the first comparison reference value and an electrical signal acquired by a feedback unit of the electrical stimulation and electric field therapy device based on an initial value of the reference voltage.

As described above, after the initial value of the reference voltage is set, the ac/dc unit outputs the stimulation current, which flows through the target object through the electrodes, by the driving signal and the reference voltage. The feedback unit collects the electric signal of the alternating current and direct current unit and outputs the electric signal to the operational amplifier branch circuit. And the operational amplifier branch circuit compares the electric signal with a first comparison reference value to realize constant current control.

And S234, adjusting the initial value of the reference voltage based on the comparison result.

The electronic equipment can determine the adjusting direction of the initial value of the reference voltage based on the judgment of the real-time sampling result of the stimulating current, so that the initial value of the reference voltage can be adjusted. Wherein, the stimulation current is sampled in real time, namely the electric signal fed back by the feedback unit; the judgment of the current real-time acquisition result is realized through an operational amplifier branch, and for the electronic equipment, the judgment result is obtained by receiving a comparison result output by the negative terminal of the operational amplifier. It should be noted that the adjustment of the reference voltage is not completed at one time, but is performed during the whole electrical stimulation process.

And S235, outputting a driving signal corresponding to the configuration parameter to the alternating current and direct current unit.

As described above, the driving signal output by the electronic device in the first mode is invariant to changes in the electrical signal, which is related to the configuration parameter. For example, the configuration parameters determine the duration and polarity of the drive signal, and the electronic device outputs the drive signal in the corresponding waveform according to the determined pulse width, i.e., the duration and polarity.

The control method for the electrical stimulation and electric field treatment device provided by the embodiment adopts the form of the branch of the operational amplifier to determine the comparison result, so that the control method can be suitable for the working mode of low current and improve the control precision in the low current mode.

In some optional implementations of this embodiment, the S235 may include:

(1) a timing time for a current polarity of the drive signal is determined based on the configuration parameter.

(2) And outputting the driving signal of the current polarity to the alternating current-direct current unit within the timing time.

(3) And when the timing time is over, switching the polarity of the driving signal and outputting the driving signal after polarity switching to the alternating current-direct current unit.

As described above, the configuration parameters determine the duration and direction of the drive signal. And when the electronic equipment outputs the driving signal with the current polarity, timing statistics is carried out. And in the timing time, the electronic equipment outputs a driving signal with the current polarity to the alternating current-direct current unit. And when the timing result reaches the timing time of the current polarity, switching the polarity of the driving signal and outputting the driving signal after polarity switching.

In a specific application example of this embodiment, the control method of the low current mode includes: the electrical stimulation and electric field therapy apparatus first performs mode selection, performs selection confirmation of implantation and non-implantation, software update, or the like, and then performs selection of stimulation sites such as muscles. And according to the selection result, parameter configuration is carried out, and then a reference voltage initial value of a proper DC-AC circuit topology is selected according to the setting. A first comparison reference value matched with the setting parameter is output through the DA of the controller according to the type and the intensity of the required waveform. According to the feedback electric signal, the output value of the reference voltage is designed and adjusted to be proper, so that the system efficiency is improved, and the heat generation of the system is controlled within a reasonable range. And when the pulse timing time reaches a set value, switching the polarity of the current. And if the electrical stimulation and electric field treatment equipment updates the parameter setting through the remote controller and continues stimulation, the electrical stimulation and electric field treatment equipment resets the first comparison reference value and the reference voltage of the level, and program circulation is carried out.

In the present embodiment, there is provided a control method for an electrical stimulation and electric field treatment device, which can be used in the controller for the electrical stimulation and electric field treatment device, where in the case that the current operation mode is the second mode, fig. 6 is a flowchart of the control method for the electrical stimulation and electric field treatment device according to the embodiment of the present invention, as shown in fig. 6, the flowchart includes the following steps:

and S31, acquiring the setting result of the current control parameters of the electric stimulation and electric field treatment device.

Please refer to S11 in fig. 4 for details, which are not described herein.

And S32, acquiring the electric signal fed back by the feedback unit.

Please refer to S12 in fig. 4 for details, which are not described herein.

And S33, adjusting the reference voltage or the driving signal of the alternating current and direct current unit based on the current working mode, the configuration parameters and the electric signal.

Specifically, S33 includes:

s331, respectively determining an initial value of the reference voltage and a second comparison reference value based on the configuration parameter.

The configuration parameters may include a range of stimulation currents, and the initial value of the reference voltage is determined based on the range of stimulation currents. For example, in the second mode, the initial value of the reference voltage is calculated directly using the maximum value of the stimulation current, and the initial value of the reference voltage is determined.

The second comparison reference value is a reference value of the drive signal closed-loop control, the subsequent feedback unit outputs the acquired electric signal to the electronic equipment, and the electronic equipment compares the electric signal with the second comparison reference value to adjust the drive signal.

And S332, controlling the direct current unit to output an initial value of the reference voltage.

After determining the initial value of the reference voltage, the electronic apparatus controls the direct current unit to output the initial value of the reference voltage. Specifically, the voltage adjustment module in the dc unit is controlled so that it outputs an initial value of the reference voltage.

S333, the electric signal is compared with a second comparison reference value.

And S334, adjusting the driving signal output to the alternating current and direct current unit based on the comparison result.

And the electronic equipment performs closed-loop control on the driving signal, receives the fed back electric signal, compares the electric signal with a second comparison reference value to obtain a comparison result, and performs closed-loop calculation. And then, the comparison result is utilized to adjust the driving signal, and the adjusted driving signal is output to the AC/DC unit.

The control method for the electrical stimulation and electric field treatment device provided by the embodiment is more efficient as a whole due to the larger current mode.

In some optional implementations of this embodiment, the step S334 may include:

(1) and adjusting the driving signal output to the alternating current-direct current unit based on the closed loop calculation result.

(2) And judging whether the timing time of the driving signal with the current polarity is finished.

Corresponding to the first mode described above, the electronic device adjusts the amplitude of the driving signal using the closed loop calculation result to meet the requirement. Meanwhile, in the process of outputting the driving signals, whether the timing time of the driving signals with the current polarity is finished or not is judged, and if not, the driving signals with the current polarity are continuously output; and if the timing time is over, switching the polarity of the driving signal and outputting the switched driving signal to the AC/DC unit.

As a specific application example of the present embodiment, in the larger current mode, if the same reference voltage adjustment method as that in the first mode is adopted, the efficiency of the electrical stimulation and electric field treatment device is reduced. Therefore, in the second mode, the set value configured according to the parameters and the electric signal sampled by the feedback unit are adopted, closed-loop calculation is performed in the controller, then the corresponding full-bridge circuit output pulse is output, and the waveform control is realized through the filter circuit.
