Description

Technical Field

[0001] This invention relates to the field of medical device electronic products, and in particular to a method and device for the neural regulation of ejaculation control by dynamic adjustment of electrical pulses. Background Technology

[0002] In recent years, physical therapy has been applied to the treatment of premature ejaculation, including devices such as premature ejaculation trainers and electrical pulse stimulation devices. Some of these trainers are large devices that require individuals to regularly visit the hospital for electrical stimulation, resulting in long stimulation cycles and frequent hospital visits. Most trainers are one-piece devices with long training cycles, making it difficult to keep the penis in an erection for extended periods, thus limiting their practicality.

[0003] Among them, electrical pulse stimulation devices release pulsed electrical stimulation through pulsed circuits, acting on the sensitive nerves of the dorsal root of the penis to lower the nerve excitation threshold, thereby effectively inhibiting nerve sensitivity and achieving effective control over the prolongation of ejaculation time. These electrical pulse stimulation devices have advantages such as miniaturization, short single-session stimulation time, and portability, and are therefore widely used.

[0004] However, existing neurostimulation devices include those that stimulate muscles or nerves in the perineal region and those that stimulate penile nerves. Stimulation of perineal muscles or nerves is indirect and does not target the dorsal root nerve of the penis, making its effectiveness uncertain and requiring prolonged use and training to achieve results. While penile nerve stimulation directly targets the dorsal root nerve, it mostly uses a single frequency stimulation signal, lacking the simultaneous generation and fusion of multi-frequency stimulation signals, thus failing to stimulate multiple neuromodulation targets simultaneously. Furthermore, it suffers from inaccurate stimulation location, non-adjustable output energy, and an inability to precisely stimulate individuals of different ages or levels of nerve sensitivity. In addition, its energy regulation relies on capacitors with fixed parameters, preventing flexible energy control and resulting in significant variations in output energy, thus affecting the effectiveness of electrical stimulation. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to disclose a method and device for the neural regulation of ejaculation control by dynamically adjusting electrical pulses; it aims to achieve effective, safe and comfortable electrical stimulation of the dorsal root nerve of the penis through multi-frequency electrical pulses with dynamically adjustable energy.

[0006] This invention discloses a method for neuromodulation of ejaculation control through dynamic adjustment of electrical pulses, comprising the following steps:

[0007] Step S1: Based on the contact resistance of the two electrodes used for stimulating the dorsal root nerve of the penis at the dorsal root of the penis, determine whether the position of the two electrodes is an effective stimulation position; if yes, proceed to the next step; if no, adjust the position of the two electrodes until it is determined to be an effective position, then proceed to the next step.

[0008] Step S2: Select at least one working mode from high frequency mode, low frequency mode, mixing mode, mixing group mode and modulation mixing mode, and output electrical pulse signals of the corresponding frequency mode to the dorsal root nerve of the penis through two electrodes for electrical stimulation.

[0009] Step S3: During the electrical stimulation process, the output energy of the electrical pulse signal is dynamically adjusted based on the contact resistance value of the two electrodes to control the dynamic balance of the charging and discharging process, so as to ensure the effectiveness and safety of the electrical stimulation.

[0010] Further, step S1 includes:

[0011] Automatically detects the impedance value between two electrodes placed at the base of the penis, or the current value indirectly represented by the impedance.

[0012] The detected impedance or current value is compared with the preset impedance or current value range of the sensitive nerve.

[0013] If the impedance detection value is within the preset impedance range or the current detection value is within the preset current range, a prompt signal indicating that the electrode is in the correct position will be provided by one or a combination of light, sound, or vibration. If the impedance or current value is not within the preset range, no prompt signal will be output. The electrode position will be adjusted until a prompt signal is output, indicating that the electrode is in the correct position.

[0014] When the electrode positions are incorrect, the two electrodes will not output pulse signals to electrically stimulate the nerve, thus avoiding stimulation of ineffective areas.

[0015] Furthermore, in step S2, the mixing mode mixes and modulates low-frequency pulse signals in the frequency range of 1KHz-100KHz and high-frequency pulse signals in the frequency range of 100KHz-500KHz through composite frequency modulation, and then outputs the mixed signal to the dorsal root nerve of the penis through two electrodes to act on multiple neuromodulation targets.

[0016] The modulation process of a frequency mixing signal includes:

[0017] 1) Output a set of low-frequency pulse signals with a frequency of 1KHz-100KHz, a voltage amplitude of 10-25V, a duration of 1ms-10ms, and an interval of 0-10ms.

[0018] 2) Change the duty cycle parameter to output a set of high-frequency pulse signals with a frequency of 100KHz-500KHz. The voltage amplitude of the high-frequency pulse electrical signal is 10-25V, and the duration of each high-frequency pulse signal is 1ms-10ms with an interval of 0-10ms.

[0019] 3) The high-frequency pulse period and the low-frequency pulse period are spaced 0-1000ms apart; the duty cycle parameter is continuously changed in a loop to alternately output high-frequency pulses and low-frequency pulses, thereby generating a set of pulse signals with alternating high-frequency and low-frequency mixing at a voltage of 10-25V.

[0020] Furthermore, in step S2, the mixing group mode will alternately output and modulate low-frequency pulse signals in the frequency range of 1KHz-100KHz and high-frequency pulse signals in the frequency range of 100KHz-500KHz, and output the mixing group pulse signals to the dorsal root nerve of the penis through two electrodes, acting on multiple neuromodulation targets.

[0021] The modulation process of a mixer-group pulse signal includes:

[0022] 1) Continuously output several sets of low-frequency pulse signals with frequencies between 1KHz and 100KHz. The voltage amplitude of the low-frequency pulse signal is 10-25V. The duration of each low-frequency pulse signal is 1ms-10ms, with an interval of 0-10ms. The entire low-frequency pulse cycle lasts 10-100ms.

[0023] 2) Change the duty cycle parameter and then continuously output multiple sets of high-frequency pulse signals with a frequency of 100KHz-500KHz. The voltage amplitude of the high-frequency pulse signal is 10-25V, the duration of each high-frequency pulse signal is 1ms-10ms, the interval is 0-10ms, and the entire high-frequency pulse cycle lasts 10-100ms.

[0024] 3) The interval between the high-frequency pulse period and the low-frequency pulse period is 100-1000ms; the duty cycle parameter is changed in this way to alternately output high-frequency pulses and low-frequency pulses, thereby generating a set of high-frequency and low-frequency alternating mixed group pulse signals with voltage of 10-25V; the interval between the high-frequency and low-frequency alternating pulse signals is 100-1000ms, and the duration is 220ms-2200ms.

[0025] Furthermore, in step S2, the modulation mixing mode mixes a low-frequency pulse signal in the frequency range of 1KHz-100KHz and a high-frequency pulse signal in the frequency range of 100KHz-500KHz to form a modulation mixing pulse, which is then output to the dorsal root nerve of the penis through two electrodes to act on multiple neuromodulation targets.

[0026] The signal modulation process of frequency modulation mixing includes:

[0027] 1) Output a 1KHz-100KHz low-frequency pulse signal with a pulse voltage of 10-25V, a duration of 1-10ms, and an interval of 0-10ms, to generate a 10-25V low-frequency stimulation pulse signal.

[0028] 2) Output a set of high-frequency pulse signals of 100KHz-500KHz, with a pulse voltage of 10-25V, a duration of 1ms-10ms, and an interval of 0-10ms, to generate a set of high-frequency stimulation pulse signals of 10-25V.

[0029] 3) By superimposing the two signals at the same time point and within the same time interval, a set of modulated mixed-frequency pulse signals with a voltage value of 10-25V, a duration of 1-10ms, and an interval of 0-10ms can be generated. At the same time, if different control methods are applied during superposition, amplitude modulation waveforms and frequency modulation waveforms can also be generated.

[0030] Further, step S3 includes:

[0031] 1) Determine the sensitivity of the dorsal root nerve of the penis; based on the resistance value of the two electrodes or the current value indirectly represented by the impedance, determine whether the sensitivity threshold of the dorsal root nerve of the penis is a high sensitivity threshold or a low sensitivity threshold.

[0032] 2) Adjust the electrical stimulation pulse energy according to the sensitivity threshold; if the dorsal root nerve of the penis is determined to be at a low sensitivity threshold, then the capacitor that generates stimulation pulses through discharge is charged with a small capacity to release low voltage electrical stimulation pulse energy; if it is at a high sensitivity threshold, then the capacitor that generates stimulation pulses through discharge is charged with a large capacity to release high voltage electrical stimulation pulse energy.

[0033] 3) Control the dynamic balance of the charging and discharging process; during the pulse discharge stage, the voltage and discharge current values ​​at the capacitor terminal are collected in real time. Through the PID control algorithm, the capacitor is dynamically charged by pulse width modulation (PWM), charging and discharging simultaneously to maintain the stability of the energy storage state inside the capacitor and achieve dynamic balance in the charging and discharging process.

[0034] This invention also discloses an ejaculation control neural modulation device that implements the ejaculation control neural modulation method of dynamic adjustment of electrical pulses as described above, comprising: a main control electrical stimulation circuit, an impedance feedback circuit, and two electrodes; wherein,

[0035] Two electrodes are placed at the base of the penis, close to the coronal sulcus;

[0036] Impedance feedback circuit is used to collect the contact resistance between the two electrodes;

[0037] The main control electrical stimulation circuit is used to generate electrical pulse signals of corresponding frequencies according to at least one of the selected high-frequency mode, low-frequency mode, mixing mode, mixing group mode and modulation mixing mode, and output them through two electrodes to electrically stimulate the dorsal root nerve of the penis.

[0038] Before electrical stimulation, the contact resistance of the two electrodes is collected by the impedance feedback circuit to determine whether the position of the two electrodes is an effective stimulation position; if yes, the ejaculation control neural modulation begins; if no, the position of the two electrodes is adjusted until it is determined to be an effective position.

[0039] During electrical stimulation, the output energy of the electrical pulse signal is dynamically adjusted based on the contact resistance value of the two electrodes collected by the impedance feedback circuit, thereby controlling the dynamic balance of the charging and discharging process to ensure the effectiveness and safety of electrical stimulation.

[0040] Furthermore, the main control electrical stimulation circuit includes a high-frequency stimulation circuit, a low-frequency stimulation circuit, and a pulse generation circuit;

[0041] The high-frequency stimulation circuit is used to generate high-frequency pulse signals within the frequency range of 100KHz-500KHz.

[0042] The low-frequency stimulation circuit is used to generate low-frequency pulse signals within the frequency range of 1KHz-100KHz.

[0043] The pulse generation circuit is used to generate an electrical pulse signal of the corresponding mode and output it to the two electrodes according to at least one of the selected high-frequency mode, low-frequency mode, mixing mode, mixing group mode and modulation mixing mode.

[0044] Furthermore, it also includes a dynamic charging circuit;

[0045] The dynamic charging circuit is used to dynamically charge the capacitor of the output electrical stimulation pulse based on the contact resistance of the two electrodes collected by the impedance feedback circuit or the current value indirectly represented by the impedance, and output an electrical stimulation pulse with corresponding energy.

[0046] Based on the resistance values ​​of the two electrodes or the current values ​​indirectly represented by the impedance, the sensitivity threshold of the dorsal root nerve of the penis is determined to be either a high sensitivity threshold or a low sensitivity threshold. If it is a low sensitivity threshold, the capacitor that generates stimulation pulses through discharge is charged with a small capacity to release low-voltage electrical stimulation pulse energy. If it is a high sensitivity threshold, the capacitor that generates stimulation pulses through discharge is charged with a large capacity to release high-voltage electrical stimulation pulse energy.

[0047] During the pulse discharge phase, the dynamic charging circuit collects the voltage and discharge current values ​​at the capacitor terminals in real time. Through a PID control algorithm, it dynamically performs pulse width modulation (PWM) charging on the capacitor to achieve the effect of charging and discharging simultaneously, maintaining the stability of the energy storage state inside the capacitor and achieving dynamic balance in the charging and discharging process.

[0048] Furthermore, it also includes a heating module;

[0049] The heating module is located at the electrode end and is used to adjust the temperature of the output electrode according to the individual's needs for electrical stimulation.

[0050] This invention can achieve one of the following beneficial effects:

[0051] This invention discloses a method and device for dynamically adjusting ejaculation control neural modulation via electrical pulses. By detecting electrode contact resistance, the device precisely locates the electrode position, ensuring it is at an effective stimulation location, thereby improving the accuracy of ejaculation control neural modulation. It provides multiple stimulation modes, including high-frequency, low-frequency, and mixed-frequency modes, to meet different neural modulation needs. It can dynamically adjust the electrical pulse energy based on contact resistance and utilize a PID control algorithm to maintain capacitor charging and discharging balance, ensuring safe and effective use. Furthermore, the device can interact with the user through lights, sound, or vibration, making operation convenient. The device is also equipped with a heating module, allowing users to adjust the electrode temperature according to their needs, increasing user comfort. Attached Figure Description

[0068] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0069] Example 1

[0070] One embodiment of the present invention discloses a method for neuromodulation of ejaculation control by dynamic adjustment of electrical pulses, such as... Figure 1 The above includes the following steps:

[0071] Step S1: Based on the contact resistance of the two electrodes used for stimulating the dorsal root nerve of the penis at the dorsal root of the penis, determine whether the position of the two electrodes is an effective stimulation position; if yes, proceed to the next step; if no, adjust the position of the two electrodes until it is determined to be an effective position, then proceed to the next step.

[0072] Step S2: Select at least one working mode from high frequency mode, low frequency mode, mixing mode, mixing group mode and modulation mixing mode, and output electrical pulse signals of the corresponding frequency mode to the dorsal root nerve of the penis through two electrodes for electrical stimulation.

[0073] Step S3: During the electrical stimulation process, the output energy of the electrical pulse signal is dynamically adjusted based on the contact resistance value of the two electrodes to control the dynamic balance of the charging and discharging process, so as to ensure the effectiveness and safety of the electrical stimulation.

[0074] Specifically, step S1 includes:

[0075] Step S101: Automatically detect the impedance value between the two electrodes placed at the base of the penis, or the current value indirectly represented by the impedance.

[0076] The distance between the two electrodes is a specific value within the range of 2-10 mm. Regarding the selection of the electrode distance, a greater distance results in a higher impedance value, indirectly manifesting as a lower current value. Furthermore, the differences in impedance or current values ​​among different skin types are greater, affecting the accuracy of the signal fed back by the impedance feedback circuit. Conversely, a closer distance results in a lower impedance value, indirectly manifesting as a higher current value, but this leads to excessive energy concentration and poor nerve stimulation. After repeated verification, this embodiment selects a specific value within the range of 2-10 mm as the distance between the two electrodes, which satisfies both the feedback accuracy of the feedback circuit and the energy distribution requirements for nerve stimulation.

[0077] Step S102: Compare the detected impedance or current value with the preset impedance or current value range of the sensitive nerve.

[0078] The preset impedance range or preset current range is a relative reference value obtained through experiments and actual clinical practice; within this range, the nerves in the dorsal root region of the penis are dense, and a better stimulation effect can be obtained.

[0079] Step S103: If the impedance detection value is within the preset impedance value range or the current detection value is within the preset current value range, a prompt signal indicating that the electrode position is correct will be provided through one or a combination of light, sound or vibration to indicate that the position is correct; if the impedance value or current value is not within the preset range, no prompt signal will be output, and the position of the electrode will be adjusted until the prompt signal is output to achieve the correct electrode position.

[0080] When the electrode positions are incorrect, the two electrodes will not output pulse signals to electrically stimulate the nerve, thus avoiding stimulation of ineffective areas.

[0081] This step allows for rapid screening of densely nerve-rich areas in the dorsal root region of the penis, further enhancing control and effectiveness of electrical stimulation, and reducing ineffective and erroneous electrical stimulation.

[0082] In this embodiment, the stimulation pulse can be a square wave pulse, a sine wave pulse, or other desired waveform pulse. The accompanying drawings in this embodiment use a sine wave pulse as an example of a waveform for generating and mixing electrical pulse signals, and are not intended to limit the electrical pulse waveform.

[0083] Specifically, in step S2, at least two types of stimulation pulses, high and low, can be output to the dorsal root nerve of the penis, and the high and low frequency stimulation pulses can be mixed; wherein, the frequency range of the low frequency pulse signal is 1KHz-100KHz; and the frequency range of the high frequency pulse signal is 100KHz-500KHz.

[0084] In step S2, the high-frequency mode and low-frequency mode are used separately to target different physiological mechanisms (such as the strength of nerve excitation). However, this is only the most basic use in this embodiment. In a more optimized application, this embodiment also provides a variety of more effective stimulation modes such as mixing mode, mixing group mode, and modulation mixing mode.

[0085] In step S2, the mixing mode mixes and modulates low-frequency pulse signals in the frequency range of 1KHz-100KHz and high-frequency pulse signals in the frequency range of 100KHz-500KHz through composite frequency modulation, and then outputs the mixed signal to the dorsal root nerve of the penis through two electrodes to act on multiple neuromodulation targets.

[0086] The modulation process of a frequency mixing signal includes:

[0087] 1) Output a set of low-frequency pulse signals with a frequency of 1KHz-100KHz, a voltage amplitude of 10-25V, a duration of 1ms-10ms, and an interval of 0-10ms.

[0088] 2) Change the duty cycle parameter to output a set of high-frequency pulse signals with a frequency of 100KHz-500KHz. The voltage amplitude of the high-frequency pulse electrical signal is 10-25V, and the duration of each high-frequency pulse signal is 1ms-10ms with an interval of 0-10ms.

[0089] 3) The high-frequency pulse period and the low-frequency pulse period are spaced 0-1000ms apart; the duty cycle parameter is continuously changed in a loop to alternately output high-frequency pulses and low-frequency pulses, thereby generating a set of pulse signals with alternating high-frequency and low-frequency mixing at a voltage of 10-25V.

[0090] like Figure 2 The diagram illustrates the waveform synthesis process of the mixing mode. The mixing mode applies waveforms of different frequencies alternately, such as a low frequency of 1kHz and a high frequency of 200kHz, simultaneously acting on multiple neuromodulation targets (such as neuronal excitability, neurotransmitter release, and synaptic plasticity). Its high-frequency components can instantly modulate the neuronal excitation threshold and inhibit pain signals (e.g., the 200kHz high-frequency component may: rapidly activate nerve fibers, increase the neuronal excitation threshold, thereby effectively delaying ejaculation impulses; may promote glutamate release, enhancing synaptic transmission efficiency); the low-frequency components can simultaneously reduce nerve sensitivity and promote tissue repair (e.g., the 1kHz low-frequency component may: reduce neuronal excitability by inducing inhibitory postsynaptic potentials (IPSPs); achieve deep tissue penetration, reducing nerve sensitivity; enhance local blood circulation, promoting tissue repair).

[0091] Compared to mixed-frequency pulse output signals that alternate between high-frequency and low-frequency signals, the mixed-frequency pulse output mode, with multiple sets of high-frequency and low-frequency alternating outputs, increases the output energy of a single frequency within the same time frame, enhancing stimulation and accelerating the establishment of nerve tolerance. The mixed-frequency pulse energy within the pulse group acts on the dorsal root nerve of the penis in a dense array, further improving the device's effectiveness in stimulating the dorsal root nerve of the penis in the recipient compared to single-frequency mixing.

[0092] In step S2, the mixing group mode alternately outputs and modulates low-frequency pulse signals in the frequency range of 1KHz-100KHz and high-frequency pulse signals in the frequency range of 100KHz-500KHz, and outputs the mixing group pulse signals to the dorsal root nerve of the penis through two electrodes, acting on multiple neuromodulation targets.

[0093] The modulation process of a mixer-group pulse signal includes:

[0094] 1) Continuously output multiple sets of low-frequency pulse signals with frequencies ranging from 1KHz to 100KHz. The voltage amplitude of the low-frequency pulse signal is 10-25V. The duration of each low-frequency pulse signal is 1ms-10ms, with an interval of 0-10ms. The entire low-frequency pulse cycle lasts 10-100ms.

[0095] 2) Change the duty cycle parameter and then continuously output multiple sets of high-frequency pulse signals with a frequency of 100KHz-500KHz. The voltage amplitude of the high-frequency pulse signal is 10-25V, the duration of each high-frequency pulse signal is 1ms-10ms, the interval is 0-10ms, and the entire high-frequency pulse cycle lasts 10-100ms.

[0096] 3) The interval between the high-frequency pulse period and the low-frequency pulse period is 100-1000ms; the duty cycle parameter is changed continuously in this way to alternately output high-frequency pulses and low-frequency pulses, thereby generating a set of high-frequency and low-frequency alternating pulse signals with a voltage of 10-25V; the interval between the high-frequency and low-frequency alternating pulse signals is 100-1000ms, and the duration is 220ms-2200ms.

[0097] like Figure 3 The image shows a schematic diagram of the waveform synthesis result in the mixing group mode.

[0098] The modulation mixing mode mixes low-frequency pulse signals in the frequency range of 1KHz-100KHz and high-frequency pulse signals in the frequency range of 100KHz-500KHz to form a modulation mixing pulse. The modulation mixing pulse signal is output to the dorsal root nerve of the penis through two electrodes and acts on multiple neuromodulation targets.

[0099] The signal modulation process of frequency modulation mixing includes:

[0100] 1) Output a set of 1KHz-100KHz low-frequency pulse signals, with a pulse voltage of 10-25V, a duration of 1-10ms, and an interval of 0-10ms, to generate a 10-25V low-frequency stimulation pulse signal.

[0101] 2) Output a set of high-frequency pulse signals of 100KHz-500KHz, with a pulse voltage of 10-25V, a duration of 1ms-10ms, and an interval of 0-10ms, to generate a set of high-frequency stimulation pulse signals of 10-25V.

[0102] 3) Superimpose the two signals at the same time point and within the same time interval to produce a set of modulated mixing pulse signals with a voltage of 10-25V, a duration of 1-10ms, and an interval of 0-10ms.

[0103] like Figure 4 The diagram shown is a schematic of the basic waveform synthesis process of the modulation mixing mode;

[0104] like Figure 5 The image shown is a schematic diagram of the amplitude modulation waveform synthesis result in the modulation mixing mode;

[0105] like Figure 6 The figure shows a schematic diagram of the frequency modulation waveform synthesis result in the modulation mixing mode.

[0106] In this embodiment, specific implementation methods and corresponding effects of high-frequency mode, low-frequency mode, mixing mode, mixing group mode and modulation mixing mode are given. Other foreseeable working modes obtained based on the same idea in this embodiment should be considered as technical solutions within the protection scope of this invention.

[0107] Specifically, step S3 includes:

[0108] Step S301: Determine the sensitivity of the dorsal root nerve of the penis; based on the resistance value of the two electrodes or the current value indirectly represented by the impedance, determine whether the sensitivity threshold of the dorsal root nerve of the penis is a high sensitivity threshold or a low sensitivity threshold.

[0109] Step S302: Adjust the electrical stimulation pulse energy according to the sensitivity threshold; if the dorsal root nerve of the penis is determined to be at a low sensitivity threshold, then the capacitor that generates stimulation pulses through discharge is charged with a small capacity to release low-voltage electrical stimulation pulse energy; if it is at a high sensitivity threshold, then the capacitor that generates stimulation pulses through discharge is charged with a large capacity to release high-voltage electrical stimulation pulse energy.

[0110] Step S303: Control the dynamic balance of the charging and discharging process; During the pulse discharge stage, the voltage value and discharge current value at the capacitor terminal are collected in real time. Through the PID control algorithm, the capacitor is dynamically charged by pulse width modulation (PWM), charging and discharging at the same time to maintain the stability of the energy storage state inside the capacitor and achieve the dynamic balance of the charging and discharging process.

[0111] Steps S301-S302 constitute a closed-loop control of neural stimulation. Considering the differences in individuals receiving electrical stimulation and age groups, the sensitivity of the skin at the base of the penis varies, and the impedance characteristics under electrical stimulation also differ. Through closed-loop control, the electrical stimulation needs of different individuals and age groups can be effectively adapted.

[0112] In closed-loop control, the corresponding electrical pulse stimulation energy is controlled based on this impedance value (for example, when dry skin causes an increase in impedance, the main control electrical stimulation circuit increases the output voltage; when moist skin causes a decrease in impedance, the main control electrical stimulation circuit decreases the output voltage). Since impedance detection is actually the dynamic change of current between the output electrodes, when static impedance detection is transformed into dynamic current monitoring, the closed-loop feedback becomes more accurate, thereby achieving a dual-mode collaborative workflow.

[0113] Closed-loop control enables personalized energy matching for different individuals, ensuring consistency in electrical stimulation effects and significantly improving safety and comfort. It upgrades the coarse discharge stimulation mode with "fixed parameters" to a precise electrical stimulation mode with "adaptive consistency".

[0114] The conventional technical solution is to charge and store energy using capacitors. This solution has two main technical limitations: First, the energy storage capacity is limited by the inherent parameters of the capacitor, making it impossible to dynamically adjust the energy. To adjust the energy, the capacitor must be replaced to change the amount of energy stored. Second, during the output pulse process, the energy stored in the capacitor is released rapidly, and the output energy gradually decreases, resulting in inconsistencies in the energy output before and after.

[0115] In step S303 of this embodiment, the dynamic balance of the charging and discharging process is controlled to precisely achieve two types of charging energy regulation.

[0116] First: Pulse Width Modulation (PWM) technology is used to dynamically adjust the capacitor charging duty cycle, thereby achieving dynamic automatic control of the capacitor's energy storage capacity. Different energies are used for electrical stimulation based on the different sensitivities of the penile skin surface of different individuals. Here, the maximum value of the capacitor's energy storage capacity can ensure the maximum energy required for electrical stimulation.

[0117] Two electrodes are placed at the dorsal root of the penis. When the dorsal root nerve sensitivity threshold of the individual being stimulated is low (i.e., more sensitive to pulsed electrical stimulation), pulse width modulation (PWM) is used to change the charging pulse width, reducing the amount of charge on the capacitor and releasing a low-voltage electrical stimulation pulse energy, which acts on the dorsal root nerve. When the dorsal root nerve sensitivity threshold of the individual being stimulated is relatively high (i.e., less sensitive to electrical pulse stimulation), pulse width modulation is used to change the charging pulse width, increasing the amount of charge on the capacitor and releasing a high-voltage electrical stimulation pulse energy, which acts on the dorsal root nerve. Through this PWM dynamic charging technology, the dynamically regulated output energy can construct a controllable energy gradient distribution according to the sensitivity level. This not only allows different individuals to receive effective stimulation, but also allows for the output of different energy stimulation pulses to different regions of the dorsal root of the penis in the same individual, making the stimulation more targeted, reducing the risk of neurovascular damage, and showing significant advantages in improving indications.

[0118] Secondly, when a certain impedance or current value is detected, the corresponding charging program is invoked to dynamically charge and discharge, generating a stimulation pulse. Furthermore, during the pulse discharge phase, the voltage and discharge current values ​​at the capacitor terminals are acquired in real time. Using existing proportional-integral-derivative (PID) control algorithms, the capacitor is dynamically charged using pulse-width modulation (PWM), achieving simultaneous charging and discharging. This maintains the stability of the capacitor's internal energy storage state, thereby achieving a dynamic balance in the charging and discharging process.

[0119] Meanwhile, during the dynamic regulation of nerve stimulation, the impedance or current value of the output electrode is detected, and corresponding control commands are output. PID and PWM technologies are used to control the energy of the stimulation pulse in real time to keep it stable, thereby obtaining a stable and effective electrical stimulation effect.

[0120] In summary, the ejaculation control neural modulation method with dynamic adjustment of electrical pulses disclosed in this embodiment accurately locates the electrode position by detecting the electrode contact resistance, ensuring that it is in an effective stimulation position, thereby improving the accuracy of ejaculation control neural modulation. It provides multiple stimulation modes, including high-frequency, low-frequency, and mixed-frequency, to meet different neural modulation needs; it can dynamically adjust the electrical pulse energy according to the contact resistance and use a PID control algorithm to maintain capacitor charging and discharging balance, ensuring safe and effective use. Furthermore, the device can interact with the user through lights, sound, or vibration, making it easy to operate.

[0121] Example 2

[0122] This embodiment discloses a neuromodulation device for ejaculation control with dynamic adjustment of electrical pulses, such as... Figure 7 As shown, it includes a main control electrical stimulation circuit, an impedance feedback circuit, and two electrodes; among which,

[0123] Two electrodes are placed at the base of the penis, close to the coronal sulcus;

[0124] Two electrodes are placed against the back of the penis. The rotation direction is adjusted so that the electrodes form a dotted line perpendicular to the penis. The electrodes are then advanced along the back of the penis towards the coronal sulcus until they are in close contact with the sulcus. The motor moves slightly left, right, up, and down around the coronal sulcus; the device will provide prompts to find the optimal position.

[0125] Impedance feedback circuit is used to collect the contact resistance between the two electrodes;

[0126] The main control electrical stimulation circuit is used to generate electrical pulse signals of corresponding frequencies according to at least one of the selected high-frequency mode, low-frequency mode, mixing mode, mixing group mode and modulation mixing mode, and output them through two electrodes to electrically stimulate the dorsal root nerve of the penis.

[0127] Before electrical stimulation, the contact resistance of the two electrodes is collected by the impedance feedback circuit to determine whether the position of the two electrodes is an effective stimulation position; if yes, the ejaculation control neural modulation begins; if no, the position of the two electrodes is adjusted until it is determined to be an effective position.

[0128] During electrical stimulation, the output energy of the electrical pulse signal is dynamically adjusted based on the contact resistance value of the two electrodes collected by the impedance feedback circuit, thereby controlling the dynamic balance of the charging and discharging process to ensure the effectiveness and safety of electrical stimulation.

[0129] The distance between the two electrodes is a specific value within the range of 2-10 mm. Regarding the selection of the electrode distance, a greater distance results in a higher impedance value, indirectly manifesting as a lower current value. Furthermore, the differences in impedance or current values ​​among different skin types are greater, affecting the accuracy of the signal fed back by the impedance feedback circuit. Conversely, a closer distance results in a lower impedance value, indirectly manifesting as a higher current value, but this leads to excessive energy concentration and poor nerve stimulation. After repeated verification, this embodiment selects a specific value within the range of 2-10 mm as the distance between the two electrodes, which satisfies both the feedback accuracy of the feedback circuit and the energy distribution requirements for nerve stimulation.

[0130] In one specific implementation, the main control electrical stimulation circuit includes a high-frequency stimulation circuit, a low-frequency stimulation circuit, and a pulse generation circuit;

[0131] The high-frequency stimulation circuit is used to generate high-frequency pulse signals within the frequency range of 100KHz-500KHz.

[0132] The low-frequency stimulation circuit is used to generate low-frequency pulse signals within the frequency range of 1KHz-100KHz.

[0133] The pulse generation circuit is used to generate an electrical pulse signal of the corresponding mode and output it to the two electrodes according to at least one of the selected high-frequency mode, low-frequency mode, mixing mode, mixing group mode and modulation mixing mode.

[0134] Employing dual independent high- and low-frequency stimulation circuits ensures synchronized output of high-frequency and low-frequency signals without crosstalk, overcoming the limitations of traditional single-circuit time-division multiplexing. The pulse signal, after mixing, combines the reliability of the low-frequency signal with the stability of the high-frequency signal. Its circuit implementation is relatively simple, and the output state is stable. Furthermore, the stimulation pulses generated by the main control electrical stimulation circuit can be square wave pulses, sine wave pulses, or pulses of other desired waveforms.

[0135] In another specific implementation, the master control electrical stimulation circuit uses a single-pulse stimulation circuit, such as... Figure 8 As shown, the single stimulation circuit design can independently complete the alternating output of high and low frequency signals by changing the duty cycle parameter of the output pulse, thereby realizing multiple working modes.

[0136] The waveform of the electrical pulse signal corresponding to each specific working mode can be found in the content disclosed in Example 1.

[0137] like Figure 9 As shown, the ejaculation control neural modulation device in this embodiment also includes a dynamic charging circuit.

[0138] The dynamic charging circuit is used to dynamically charge the capacitor of the output electrical stimulation pulse based on the contact resistance of the two electrodes collected by the impedance feedback circuit or the current value indirectly represented by the impedance, and output an electrical stimulation pulse with corresponding energy.

[0139] Based on the resistance values ​​of the two electrodes or the current values ​​indirectly represented by the impedance, the sensitivity threshold of the dorsal root nerve of the penis is determined to be either a high sensitivity threshold or a low sensitivity threshold. If it is a low sensitivity threshold, the capacitor that generates stimulation pulses through discharge is charged with a small capacity to release low-voltage electrical stimulation pulse energy. If it is a high sensitivity threshold, the capacitor that generates stimulation pulses through discharge is charged with a large capacity to release high-voltage electrical stimulation pulse energy.

[0140] During the pulse discharge phase, the dynamic charging circuit collects the voltage and discharge current values ​​at the capacitor terminals in real time. Through a PID control algorithm, it dynamically performs pulse width modulation (PWM) charging on the capacitor to achieve the effect of charging and discharging simultaneously, maintaining the stability of the energy storage state inside the capacitor and achieving dynamic balance in the charging and discharging process.

[0141] For specific technical details of the dynamic charging circuit, please refer to the content disclosed in Embodiment 1.

[0142] like Figure 10 As shown, the ejaculation control neuromodulation device of this embodiment also includes a heating module; the heating module is disposed at the electrode end and is used to adjust the temperature of the output electrode according to the needs of the individual receiving electrical stimulation, so as to adapt to the temperature needs of different individuals receiving stimulation and the seasonal adaptability of the device.

[0143] In more specific designs, the ejaculation control neural modulation device may also include buttons, indicator lights, a miniature speaker, and may also include a miniature vibration motor; among these,

[0144] The button is a multi-function button that can be used to turn the device on and off, as well as select the working mode; the indicator light, miniature speaker, and miniature vibration motor are used to enable the device to interact with the individual receiving nerve stimulation through sound, light, and vibration.

[0145] After the device is powered on, the button indicator light will illuminate. Pressing the button again, accompanied by an audible prompt, allows you to set the device's operating mode. The device has settings 1 to n, corresponding to the high-frequency mode, low-frequency mode, mixing mode, mixing group mode, and modulation mixing mode, respectively. If the individual receiving the electrical stimulation has not set an operating mode, the device will default to Auto mode upon power-on; in Auto mode, the electrical pulses are output using any one of the mixing, mixing group, or modulation mixing modes.

[0146] In one embodiment of the device, the impedance feedback circuit feeds back an impedance value, such as... Figure 11 As shown, the specific work process includes:

[0147] Press and hold the button on the ejaculation control neuromodulation device for 1-2 seconds to turn it on. Then, place the output electrode of the device against the base of the penis. After the device is turned on, press the button and follow the audio prompts to set the device to the selected operating mode.

[0148] The device detects the impedance value between the output electrodes through an impedance feedback circuit and feeds it back to the main control electrical stimulation circuit. The main control electrical stimulation circuit has a built-in impedance range for the sensitive nerves of the individual experiencing premature ejaculation (this range is a relative reference value obtained through experiments and clinical practice). The main control electrical stimulation circuit compares the built-in reference value with the impedance detection feedback value. If the impedance feedback circuit detects an impedance value Z = 1000-3000Ω, it indicates that the output electrode is in the correct position suitable for electrical stimulation of the dorsal root of the penis, and the nerves in this area are relatively sensitive. In this case, the main control electrical stimulation circuit will control the indicator light on the device to illuminate, indicating that the nerves in this area are sensitive and complete electrical stimulation can be performed in this dorsal root region. If the impedance feedback circuit detects an impedance value Z < 500Ω or Z > 3000Ω, it indicates that the output electrode is in an unsuitable position in the dorsal root region of the penis, and there may be damage or insensitivity in this area. In this case, the main control electrical stimulation circuit will control the indicator light to turn off, indicating that electrical stimulation is not needed in this area or that the epidermis in this area is damaged.

[0149] After the correct position is detected, the main control electrical stimulation circuit outputs a control command according to the impedance value, which controls the discharge capacitor to output 10-25V of energy to the output electrode to electrically stimulate the dorsal root nerve of the penis.

[0150] During stimulation, when the impedance feedback circuit detects an increase in impedance, the main control electrostimulation circuit increases the output voltage; when the impedance feedback circuit detects a decrease in impedance, the main control electrostimulation circuit decreases the output voltage. In this way, the main control electrostimulation circuit can promptly calibrate the output energy to address impedance fluctuations caused by changes in skin condition. Furthermore, due to real-time impedance feedback—that is, the dynamic changes in current between the output electrodes—the main control electrostimulation circuit automatically matches the optimal energy output. Simultaneously, through dynamic monitoring of the current, if the output electrode shifts to a non-target area during electrostimulation, an abnormal current occurs, the indicator light goes out, and the main control electrostimulation circuit instantly cuts off the energy output, achieving closed-loop precise feedback and thus realizing a dual-mode collaborative workflow.

[0151] In another embodiment of the device, such as Figure 12As shown, the impedance feedback circuit indirectly feeds back the detected impedance value in the form of current. At this time, the dynamic change of current between the output electrodes of the device will be fed back to the main control electrical stimulation circuit in real time. The main control electrical stimulation circuit has a specific current range for sensitive nerves (this current range is a relative reference value obtained through experiments and actual clinical practice). The main control electrical stimulation circuit will compare the built-in current reference range with the real-time monitored current value. If the impedance feedback circuit detects a current between the output electrodes of i = 0.1mA-2mA, it indicates that the output electrodes are in the correct position for electrical stimulation of the dorsal root of the penis, and the nerves in this area are relatively sensitive. In this case, the main control electrical stimulation circuit will illuminate the indicator light on the device, indicating that the nerves are sensitive and complete electrical stimulation can be performed in this dorsal root region. Current monitoring achieves precise targeting of the active nerve bundle. If the impedance feedback circuit detects an impedance value i < 0.1mA or i > 2mA, it indicates that the output electrodes are in an unsuitable position for electrical stimulation of the dorsal root of the penis, and there may be damage or insensitivity in this area. In this case, the main control electrical stimulation circuit will extinguish the indicator light, indicating that electrical stimulation is unnecessary or that there is damage to the skin in this area. Current monitoring immediately blocks ineffective stimulation. This dynamic detection method, which monitors the working current between the output electrodes, is more accurate than the static detection method, which monitors the impedance between the output electrodes.

[0152] In another embodiment of the device, the internal control circuit of the ejaculation control neuromodulation device, in addition to the main control electrical stimulation circuit and the impedance feedback circuit, includes a dynamic charging circuit. For example... Figure 13 As shown, the specific work process includes:

[0153] Press and hold the button of the ejaculation control nerve modulation device for 1-2 seconds to turn on the device, and then place the output electrode of the device against the base of the penis. After the device is turned on, press the button and follow the sound prompts to set the device to the selected operating mode.

[0154] The device detects the impedance value between the output electrodes through the impedance feedback circuit and feeds it back to the main control electrical stimulation circuit. The main control electrical stimulation circuit compares this impedance with the built-in impedance range. For example, when the output electrode detects an impedance value Z = 800-1500Ω, the device indicator light illuminates, indicating that the output electrode is in the correct position suitable for electrical stimulation of the dorsal root of the penis, and that the nerve sensitivity threshold of the dorsal root of the penis is low at this location (i.e., it is more sensitive to pulsed electrical stimulation). The main control electrical stimulation circuit outputs a control command, which enters the dynamic charging circuit. The dynamic charging circuit starts PWM to charge the charging capacitor with a small capacity, such as 5-10V, according to the command. Then, the main control electrical stimulation circuit controls the charging capacitor to output 5-10V pulse energy to the target area. The output electrode is applied to the sensitive nerve at the dorsal root of the penis to achieve gentle electrical stimulation with low energy. When the output electrode detects an impedance value Z = 2800-3000Ω, the device indicator light illuminates, indicating that the output electrode is in the correct position for electrical stimulation at the dorsal root of the penis. However, the nerve sensitivity threshold at this location is relatively high (i.e., not very sensitive to electrical pulse stimulation). The main control electrical stimulation circuit outputs a control command, which is sent to the dynamic charging circuit. The dynamic charging circuit, according to the command, activates PWM to charge the charging capacitor to a large capacity, such as 20-25V. Then, the main control electrical stimulation circuit controls the charging capacitor to output 20-25V pulse energy to the output electrode, which acts on the sensitive nerve at the dorsal root of the penis to achieve strong electrical stimulation with high energy. Through this PWM dynamic charging technology, the output dynamically adjustable energy can construct a controllable energy gradient distribution according to the needs of different individuals receiving electrical stimulation. This not only allows different people to obtain effective and comfortable electrical stimulation when using the device, but also allows different energy electrical stimulation effects to be output to different areas of the dorsal root of the penis of the same individual. This technology is particularly advantageous in reducing the risk of injury and expanding the range of indications. After stimulation, press and hold the device button for 2-3 seconds to stop the device from working and turn it off.

[0155] In another embodiment of the device, a PID control algorithm is also used to control the simultaneous charging and discharging of the capacitor in the dynamic charging circuit; such as Figure 14 As shown, the specific work process includes:

[0156] Press and hold the button of the ejaculation control nerve modulation device for 1-2 seconds to turn on the device, and then place the output electrode of the device against the base of the penis. After the device is turned on, press the button and follow the sound prompts to set the device to the selected operating mode.

[0157] The device detects the impedance value between the output electrodes through the impedance feedback circuit and feeds it back to the main control electrical stimulation circuit. The main control electrical stimulation circuit compares the impedance with the built-in impedance range. For example, when the output electrode detects an impedance value Z = 1000-3000Ω, the device indicator light illuminates, indicating that the output electrode is in the correct position for electrical stimulation of the dorsal root of the penis. The main control electrical stimulation circuit outputs a control command, which enters the dynamic charging circuit. The dynamic charging circuit starts the PWM charging program according to the command to charge the charging capacitor, such as charging the capacitor to 10-25V. Then, the main control electrical stimulation circuit controls the charging capacitor to output 10-25V pulse energy to the output electrode, which acts on the sensitive nerve at the dorsal root of the penis for electrical stimulation. During the release of pulse energy from the capacitor, the dynamic charging circuit continuously monitors the voltage and discharge current at the capacitor terminals. As the pulse energy is released, when the voltage at the capacitor terminals is detected to be below (10-25V) ± 20% (relative to the set value) or the discharge current is below 5mA, the PID control algorithm within the dynamic charging circuit is invoked, and a command is output. The dynamic charging circuit then initiates a PWM charging program to charge the capacitor according to the command. Charging stops when the capacitor voltage reaches (10-25V). The circuit then continues to monitor the voltage amplitude at the capacitor terminals. When the voltage amplitude again falls below (10-25V) ± 20% or the discharge current falls below 5mA, the PID control algorithm within the dynamic charging circuit is invoked again, and a command is output. The dynamic charging circuit then initiates a PWM charging program to charge the capacitor according to the command. Charging stops when the capacitor amplitude reaches (10-25V), and this cycle repeats continuously. This technology, which dynamically adjusts the PWM charging process by monitoring the voltage and discharge current of the charging capacitor in real time using a PID control algorithm, achieves simultaneous charging and discharging of the capacitor, thus maintaining a stable internal energy storage state and achieving dynamic balance in the charging and discharging process. This ensures that the energy output from the output electrodes remains consistent throughout use, resulting in a stable and effective electrical stimulation effect. After the electrical stimulation is complete, press and hold the device button for 2-3 seconds to stop the device and power it off.

[0158] In another embodiment of the device, a standby extension function is also implemented. The specific working process includes:

[0159] Press and hold the button of the ejaculation control nerve modulation device for 1-2 seconds to turn on the device, and then place the output electrode of the device against the base of the penis.

[0160] If, due to various external environmental factors, the individual receiving electrical stimulation does not use the device promptly after it is turned on, or if the output electrode fails to find the correct position at the base of the penis for an extended period, the indicator light will not illuminate. This indicates that the impedance between the output electrodes detected by the impedance feedback circuit is infinite or the current value is 0mA. The impedance feedback circuit will feed the detected value back to the main control electrical stimulation circuit. The main control electrical stimulation circuit will output a command based on the feedback value to control the discharge capacitor to disconnect from discharge, and simultaneously output a command to instruct the dynamic charging circuit to call the charging program. The dynamic charging circuit disconnects the charging capacitor through PWM, reducing the power consumption of this part of the circuit to 0. At this time, the device only retains the sensing function of the output electrode by the impedance feedback circuit. The other main control electrical stimulation circuit, the dynamic charging circuit, and surrounding auxiliary circuits and electronic components will enter a dormant state. The device will reduce to the lowest power consumption state of the powered-on state, with power consumption close to and less than 1mA.

[0161] When the individual receiving electrical stimulation begins using the device again, or when the output electrodes are correctly positioned against the dorsal root of the penis, the impedance feedback circuit senses external changes in the output electrodes and initiates impedance detection between them. Simultaneously, it activates the main control electrical stimulation circuit, the dynamic charging circuit, and surrounding auxiliary circuits and electronic components, bringing the device into normal operation. The impedance feedback circuit feeds back the impedance value to the main control electrical stimulation circuit, which outputs a command based on the feedback value to control the discharge of the charging capacitor. Simultaneously, it outputs a command to the dynamic charging circuit to invoke the charging program. The dynamic charging circuit charges the charging capacitor via PWM, and the device begins normal output with a power consumption of 50mA.

[0162] Therefore, by designing a standby extension function for the device, the power consumption difference between the working and standby states is approximately 40mA. This programming design enables an effective intelligent mode where the device operates in standby mode when there is no stimulation and automatically operates when stimulated, significantly reducing power consumption, greatly minimizing ineffective energy loss, increasing the device's usage frequency, and extending its lifespan. After electrical stimulation is complete, pressing and holding the device button for 2-3 seconds will stop the device and power it off.

[0163] In another embodiment of the device, the temperature of the output electrode is adjusted by a heating module according to the individual's needs for electrical stimulation; such as Figure 15 As shown, the specific work process includes:

[0164] Press and hold the button of the ejaculation control nerve modulation device for 1-2 seconds to turn on the device, and then place the output electrode of the device against the base of the penis.

[0165] If the output electrode temperature feels too low, affecting the user experience, quickly press the button twice (double-click, accompanied by an audible prompt) to activate the heating module. Heating and electrical stimulation can be performed simultaneously; a noticeable temperature increase is usually felt within 5-10 seconds. If the patient feels the output electrode temperature is too high, quickly press the button twice again (double-click, accompanied by an audible prompt) to deactivate the heating module and stop heating.

[0166] Preferably, the heating module is made of a composite material (such as a graphene and aerogel composite) and has the following two functions.

[0167] First, the effectiveness of temperature changes. When heating is turned on, the heating module heats up rapidly, allowing the patient to effectively feel the increase in temperature at the tip of their head; when heating is turned off, the heating module cools down slowly, preventing the patient from feeling a rapid drop in temperature. This design, with its rapid heating and slow cooling, aims to ensure that during heating, the power allocated to the heating module allows for a rapid temperature increase; and when heating is turned off, it allows for slow heat dissipation. This not only improves the efficiency of temperature changes but also significantly reduces the device's output power consumption.

[0168] Secondly, the temperature variation is limited. The heating module is made of composite materials, and the temperature it can reach under different external power conditions has a corresponding range limit. The power allocated to the heating module by this ejaculation control nerve modulation device allows the temperature of the heating module to rise to 35±2°C, after which the temperature will not rise further, thereby avoiding damage to the patient's nerves due to excessive temperature.

[0169] Therefore, this head-end heating module design not only enhances the device's adaptability to different seasons, but also significantly improves patients' willingness and comfort in receiving electrical stimulation.

[0170] After the electrical stimulation is complete, press and hold the device button for 2-3 seconds to stop the device from working and turn it off.

[0171] In summary, the integrated navigation fault detection method based on spiking neural networks disclosed in this embodiment enhances the system's sensitivity to faults and improves fault detection performance by utilizing the feature recognition and learning capabilities of SNNs for time series data.

[0172] Spike neural networks (SNNs) have excellent time-series information processing capabilities. They can fully utilize the time-series characteristics of innovation vectors to capture instantaneous changes and dynamic processes during fault occurrence. Compared with traditional fault detection methods based on artificial neural networks, they are more adaptable to application scenarios with strong time-series characteristics, such as integrated navigation systems.

[0173] In summary, the ejaculation control neuromodulation device with dynamic electrical pulse adjustment disclosed in this embodiment accurately locates the electrodes by detecting their contact resistance, ensuring they are in an effective stimulation position and thus improving the accuracy of ejaculation control neuromodulation. It provides multiple stimulation modes, including high-frequency, low-frequency, and mixed-frequency, to meet different neuromodulation needs; it can dynamically adjust the electrical pulse energy based on the contact resistance and uses a PID control algorithm to maintain capacitor charging and discharging balance, ensuring safe and effective use. Furthermore, the device can interact with the user through light, sound, or vibration, making it easy to operate. The device is also equipped with a heating module, allowing users to adjust the electrode temperature according to their needs, increasing user comfort.

[0174] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
