Description

Technical Field

[0001] This disclosure relates to the field of blood glucose control, and more particularly to a blood glucose control device based on electrical stimulation. Background Technology

[0002] Currently, the control of hyperglycemia mainly includes medication and lifestyle interventions. Medication, such as insulin injections and various oral hypoglycemic agents, is a common method; however, long-term use may cause side effects, and some users develop drug resistance. Furthermore, while lifestyle interventions such as dietary control and exercise are beneficial, their implementation requires a high degree of self-discipline and their effectiveness is limited. Therefore, blood glucose control is neither effective nor precise. Utility Model Content

[0003] In view of this, the purpose of this disclosure is to provide an electrical stimulation-based blood glucose control device to at least solve one of the above-mentioned technical problems.

[0004] A first aspect of this disclosure provides an electrical stimulation-based blood glucose control device, comprising:

[0005] The power module is used to provide the operating voltage;

[0006] An interactive interface, connected to the power module, is used to indicate electrical stimulation parameters and / or set electrical stimulation parameters based on user operation; the electrical stimulation parameters include at least one of the following: the frequency or intensity of an electrical pulse signal;

[0007] An electrical pulse generator, connected to the interactive interface, is used to generate the corresponding electrical pulse signal based on the electrical stimulation parameters;

[0008] An electrode, connected to the electrical pulse generator, is used to transmit the target electrical pulse signal to the target area of ​​the target object.

[0009] As can be seen from the above, the electrostimulation-based blood glucose control device provided in this disclosure uses transcutaneous electrical stimulation of specific acupoints to non-invasively control the ecological balance of the intestinal flora, promoting the growth and reproduction of beneficial bacteria and inhibiting harmful bacteria. This improves intestinal barrier function, reduces insulin resistance caused by endotoxins entering the bloodstream, and effectively lowers blood glucose levels. Compared with drug control, it reduces the risk of drug side effects; compared with traditional intestinal flora control methods, it improves the accuracy and stability of control.

Obviously, the accompanying drawings described below are only embodiments of this disclosure.

[0016] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] Currently, the control of hyperglycemia mainly includes medication and lifestyle interventions. Medication, such as insulin injections and various oral hypoglycemic agents, is a common method; however, long-term use may cause side effects, and some users develop drug resistance. Lifestyle interventions, such as dietary control and exercise, while beneficial, require high levels of self-discipline and have limited effectiveness. In recent years, the role of gut microbiota in blood glucose control has gradually gained attention. Some studies have attempted to control gut microbiota by directly administering probiotics or using special diets, but these methods suffer from problems such as unstable gut microbiota colonization and significant individual variability in the effects of probiotics, making it difficult to precisely regulate the composition and function of the gut microbiota. Therefore, improving the accuracy of blood glucose control has become an urgent technical problem to be solved.

[0019] Therefore, the electrostimulation-based blood glucose control device disclosed herein uses transcutaneous electrical stimulation of specific acupoints to non-invasively control the ecological balance of the gut microbiota, promoting the growth and reproduction of beneficial bacteria and inhibiting harmful bacteria. This improves intestinal barrier function, reduces insulin resistance caused by endotoxins entering the bloodstream, and effectively lowers blood glucose levels. Compared with drug control, it reduces the risk of drug side effects; compared with traditional gut microbiota control methods, it improves the accuracy and stability of control.

[0020] See Figure 1 , Figure 1 A schematic diagram of an electrically stimulated blood glucose control device according to an embodiment of the present disclosure is shown. The electrically stimulated blood glucose control device 100 according to an embodiment of the present disclosure may include:

[0021] Power module 110 is used to provide operating voltage;

[0022] An interactive interface 120, connected to a power module 110, is used to indicate electrical stimulation parameters and / or set electrical stimulation parameters based on user operation; the electrical stimulation parameters include at least one of the following: the frequency or intensity of an electrical pulse signal;

[0023] An electrical pulse generator 130 is connected to the interactive interface 120 and is used to generate corresponding electrical pulse signals based on the electrical stimulation parameters.

[0024] Electrode 140 is connected to the electrical pulse generator 130 and is used to transmit the electrical pulse signal to the target area of ​​the target object.

[0025] The power module 110 provides a stable operating voltage for the entire device, ensuring the normal operation of other modules. For example, the power module 110 can use a rechargeable lithium battery to meet the needs of long-term nighttime use and is equipped with a power display and low-battery reminder function to ensure the control process is not affected by power levels. The interactive interface 120 can indicate electrical stimulation parameters. This can be done by displaying the current electrical stimulation parameter value in a display area, or by pointing to a parameter value indicated by an adjustment component (e.g., a scale for electrical stimulation parameters is printed on the interactive interface, and the adjustment component can point to a parameter value to indicate the current value. The user can change the parameter value indicated by the adjustment component, thereby adjusting the electrical stimulation parameters). The user operates through the interactive interface 120, such as setting electrical stimulation parameters (e.g., current intensity, pulse frequency, pulse width, etc.). After detecting the user's operation, the interactive interface 120 transmits these parameters to the current generator 130. The electrical pulse generator 130 generates corresponding electrical pulse signals based on the electrical stimulation parameters received from the interactive interface 120. These signals have specific waveforms, frequencies, and intensities, designed to be transmitted to the target area of ​​the target object through electrode patches. Electrode 140 can be closely attached to a target area of ​​a target object (such as a human body), for example, electrode 140 can be an electrode patch. When the electrical pulse generator generates electrical pulse signals, these signals are conducted through the electrodes to the target area, thereby stimulating the nerve or muscle tissue in that area. For example, in terms of blood glucose control, electrical stimulation may lower or maintain blood glucose levels by influencing insulin secretion, improving insulin resistance, or controlling appetite.

[0026] The frequency of an electrical pulse signal refers to the number of times the signal repeats per unit time, usually measured in Hertz (Hz). Different frequencies correspond to different biological effects. For example, low-frequency electrical stimulation may be more suitable for promoting muscle relaxation and relieving pain, while high-frequency stimulation may be more suitable for promoting muscle contraction and increasing muscle strength. By adjusting the frequency, the effects of electrical stimulation on biological tissues can be precisely controlled to achieve specific effects. The intensity of an electrical pulse signal refers to its amplitude or power, measured in milliamperes (mA) or volts (V). The intensity directly determines the degree of stimulation to biological tissues. By precisely adjusting these parameters, personalized electrical stimulation control can be achieved, thereby maximizing control effectiveness and minimizing potential risks.

[0027] Therefore, through the interactive interface, users can set appropriate electrical stimulation parameters according to their own circumstances to achieve personalized blood glucose control. Compared with traditional drug control or insulin injection, this device uses electrical stimulation, eliminating the need for skin punctures or oral medication, thus reducing user pain and inconvenience. The electrical pulse signals generated by the current generator have precise control functions, ensuring safety and comfort during the control process. At the same time, the electrode patch design also takes into account the adaptability and safety of human skin.

[0028] In some embodiments, the electrical pulse generator includes:

[0029] A frequency generator for generating the electrical pulse signal based on the electrical stimulation parameters;

[0030] The first coil is connected to the frequency generator and is used to generate a corresponding induced electric field based on the electrical pulse signal;

[0031] The second coil, corresponding to the first coil, is used to receive the electrical pulse signal based on the induced electric field.

[0032] A frequency generator is a device that produces pulses with adjustable width, amplitude, and repetition frequency. Specifically, a frequency generator may include: an oscillator responsible for generating a stable oscillating signal at a certain frequency, such as a square wave or sine wave; a counter used to count the signal generated by the oscillator, recording the period of the oscillation signal to a fixed value; a multivibrator circuit that can frequency-convert the signal output from the counter, obtaining the desired output frequency through frequency division or multiplication; and a trigger that can switch the signal output from the multivibrator circuit to generate continuous pulse signals. The electrical pulse signals generated by the frequency generator can serve as an important means of bioelectric stimulation experiments and control. Its working principle is to convert the power supply current into an output signal with a specific current waveform through a circuit, which is then used to electrically stimulate a target object (e.g., biological tissue) through output electrodes. When current passes through the organism, an electrochemical reaction occurs between the electrodes and the target object, producing electrolytes and ions. These ions migrate under the influence of an electric field, thereby producing a stimulating effect on the target object. Different pulse waveforms and parameters can produce different stimulating effects, such as muscle contraction and nerve conduction inhibition.

[0033] Specifically, see Figure 2 , Figure 2 A schematic diagram of an electrical pulse generator according to an embodiment of the present disclosure is shown. Figure 2In this device, the electrical pulse generator includes a frequency generator and a first coil connected in series, with a second coil corresponding to the first coil. The frequency generator can be connected to a power module and converts the input signal into an electrical pulse signal, which is transmitted to an electrode via an induced electric field between the first and second coils. Specifically, the electrode can include a first electrode and a second electrode, which can be electrode patches used to transmit the electrical pulse signal from the second coil to a target area of ​​a target object. For example, the electrical pulse signal can be transmitted to an acupoint on the human body by clicking the patch.

[0034] In some embodiments, the first coil includes a first input terminal, a first intermediate terminal, and a first output terminal. The first input terminal and the first output terminal are connected to the electrical stimulation generator. A first wire between the first input terminal and the first intermediate terminal is parallel to a second wire between the first intermediate terminal and the first output terminal.

[0035] The first coil can be configured using a dual-circuit design, such as... Figures 3-4 As shown, Figures 3-4 A schematic diagram of the first coil is shown. Figures 3-4 In this design, the first coil includes a first input terminal A, a first intermediate terminal O, and a first output terminal B. The first input terminal A and the first output terminal B are connected to an electrical stimulation generator. A first wire between the first input terminal A and the first intermediate terminal O is parallel to a second wire between the first intermediate terminal O and the first output terminal B. This helps ensure a uniform current distribution within the coil, thereby improving the coil's performance and efficiency. Furthermore, the parallel wire arrangement may also help reduce electromagnetic interference and energy loss.

[0036] In some embodiments, the second coil includes a second input terminal and a second output terminal, and the electrode includes a first electrode and a second electrode, with the second input terminal and the second output terminal respectively connected to the first electrode and the second electrode;

[0037] The second coil also includes a second intermediate terminal, and a third wire between the second input terminal and the second intermediate terminal is parallel or serial with a fourth wire between the second intermediate terminal and the second output terminal.

[0038] The second coil can be configured in a dual-circuit or single-circuit manner, such as... Figures 5-6 As shown, Figures 5-6 A schematic diagram of the second coil is shown. Figure 5 In the second coil, there are a second input terminal C, a second intermediate terminal O' and a second output terminal D. The second input terminal C and the second output terminal D are connected to the electrical stimulation generator. The third wire between the second input terminal C and the second intermediate terminal O' and the fourth wire between the second intermediate terminal O' and the second output terminal D are parallel. Figure 6In the circuit, the second input terminal C and the second output terminal D are connected to the electrical stimulation generator, and the third wire between the second input terminal C and the second intermediate terminal O' and the fourth wire between the second intermediate terminal O' and the second output terminal D are connected in series.

[0039] In some embodiments, the electrical stimulation parameters have default values;

[0040] The electrical pulse generator is also used to generate a periodic first electrical pulse signal based on the default value. The first electrical pulse signal in each period includes one or more signal types, including: triangular wave, rectangular wave, sine half wave, spike wave or step wave.

[0041] The waveform of an electrical pulse signal describes the shape or pattern of its change over time. Examples include square waves, sine waves, and triangular waves. Different waveforms have different effects on biological tissues. For instance, square waves may produce a more direct and intense stimulation, while sine waves may be smoother and provide a relatively gentler stimulation. Choosing an appropriate waveform helps optimize the effect of electrical stimulation while reducing potential damage to biological tissues.

[0042] Sampling various types of electrical pulse signals can stimulate nerve cells and muscle fibers, triggering more complex physiological responses. These responses include muscle contraction, nerve excitation, and improved blood circulation, helping to relieve muscle fatigue, reduce pain, and promote tissue repair on multiple levels. Different types of electrical pulse signals have different stimulating effects on tissues; for example, triangular waves may focus more on promoting blood circulation, while rectangular waves may emphasize muscle contraction. Therefore, the waveform of an existing electrical pulse signal can be selected through the first user operation, such as... Figure 7 As shown, Figure 7 A waveform diagram of an electrical pulse signal according to an embodiment of the present disclosure is shown. Figure 7 The combination of multiple signal types in electrical pulse signal sampling can produce a more comprehensive therapeutic effect. Furthermore, users have different needs, and a single signal type of electrical pulse signal may not meet the treatment requirements of all users. Combinations of multiple signal types can be personalized according to the specific circumstances of each user, thus providing more precise treatment.

[0043] In some embodiments, the user operation is used to set the electrical stimulation parameters to a target value;

[0044] The electrical pulse generator is also used to generate a periodic second electrical pulse signal based on the target value, the second electrical pulse signal including a triangular wave, a rectangular wave, a half-sine wave, a spike wave, or a stepped wave.

[0045] In some embodiments, the interactive interface 120 includes an operation panel and a display panel.

[0046] Specifically, the control panel may include a series of buttons or knobs that users can use to set and adjust electrical stimulation parameters, such as current intensity, pulse frequency, and pulse width. The display panel can show various information about the electrical stimulation-based blood glucose control device, such as the currently set electrical stimulation parameters, battery level, operating time, and other current operating status or parameter settings. The display panel can use an LCD or LED display screen, providing clear display and high brightness to ensure normal information display under various lighting conditions. Furthermore, the display panel may support multiple languages ​​to meet the needs of different users.

[0047] In some embodiments, the interactive interface 120 includes a touch display interface.

[0048] Specifically, users can set and adjust electrical stimulation parameters and view various information by touching icons or buttons on the screen. The touch display interface also supports gesture operations such as swiping and zooming, improving the convenience and flexibility of user operation. For example, the touch display interface can adopt a graphical interface design, allowing users to operate through intuitive icons and buttons without having to read complicated manuals. Users can personalize the layout, colors, fonts, and other settings of the touch display interface according to their preferences and needs. The touch display interface supports displaying multiple windows or applications simultaneously, allowing users to easily switch between different tasks. The touch display interface can also provide prompting functions, such as parameter setting range prompts and error operation warnings, to help users avoid accidental operations.

[0049] In some embodiments, the electrode 140 is made of a conductive material. Specifically, the electrode 140 may be an electrode patch made of a soft, conductive, and non-irritating material. Its shape can be arbitrary, for example, designed to conform to the contours of acupoints on the human body for better transmission of electrical stimulation.

[0050] In some embodiments, the device 100 may further include a communication module for receiving external detection data. The external detection data may be blood glucose detection data from an external device (e.g., a blood glucose meter). For example, the communication module may be wired communication or wireless communication (e.g., Bluetooth communication).

[0051] In some embodiments, the device 100 may further include: a control module connected to the communication module, configured to update the default value based on the blood glucose detection data to update the first electrical pulse signal.

[0052] The control module can automatically adjust the electrical stimulation parameters based on the external detection data. For example, by linking with external devices, it can monitor blood glucose levels in real time and automatically adjust the electrical stimulation parameters as needed, i.e., adjust the waveform of the electrical pulse signal, to achieve better control.

[0053] In practical use, a target area on the target object can be identified. Taking the human body as an example, the target area can be acupoints closely related to intestinal function and blood sugar control, such as Zusanli, Sanyinjiao, and Tianshu. Before use, the skin around the target area (e.g., acupoints) should be cleaned to ensure there is no oil, dirt, or other substances that could affect the conductivity of the electrode patch. The electrode patch should be accurately attached to the corresponding acupoints according to their distribution, ensuring a tight fit between the electrode patch and the skin, without wrinkles or air bubbles, to ensure that the electrical pulses can be effectively conducted to the tissue at the acupoints. The electrode patch is connected to the electrical stimulation generator via wires, and the user enters the parameter setting mode through the human-computer interaction interface. Basic user information, such as age, gender, weight, blood sugar level, and past medical history, can be entered into the human-computer interaction interface to initially determine the frequency and intensity range of the electrical pulses. For example, for a typical adult with high blood sugar, the initial frequency can be set between 10Hz and 50GHz, and the intensity between 0mA and 10mA. Considering the special nature of nighttime control, the frequency can be appropriately shifted to the lower frequency range, such as 0Hz-30Hz, and the intensity can also be slightly reduced, such as 0mA-6mA, to reduce interference with the user's sleep while maintaining the control effect.

[0054] During the control process, if the user experiences decreased sleep quality at night due to electrical stimulation, the electrical stimulation parameters can be further fine-tuned through the human-computer interaction interface. For example, the frequency can be reduced by 2Hz-5Hz and the intensity by 0.5mA-1mA each time. The electrical stimulation parameters can be adjusted as needed to achieve the optimal combination of parameters that ensures the control effect while minimizing sleep disturbance. During daytime use, the parameters can be appropriately increased based on the user's tolerance and blood glucose monitoring results. The frequency can be adjusted to 20Hz-50Hz and the intensity to 4mA-10mA.

[0055] After parameter settings are completed, the electrical stimulation generator produces periodic electrical pulse signals according to the set parameters, performing transcutaneous electrical stimulation control. The electrical pulse signals are transmitted to the skin, nerves, and muscle tissue at the acupoints via electrode patches. The electrical pulses stimulate nerve endings around the acupoints, causing nerve impulse conduction. These nerve impulses are transmitted along nerve fibers to the central nervous system and, through the complex control mechanism of the neuro-endocrine-immune network, affect the autonomic nervous system innervation and blood circulation of the intestines. For example, stimulation may control the balance of the sympathetic and parasympathetic nervous systems in the intestines, promoting intestinal peristalsis and digestive juice secretion, and improving the intestinal environment. Simultaneously, electrical stimulation may also affect the permeability and immune function of the intestinal mucosa, promoting the growth and reproduction of beneficial bacteria and inhibiting the growth of harmful bacteria. With the optimization of the intestinal flora structure, the intestinal barrier function is enhanced, reducing the amount of endotoxins entering the bloodstream, thereby reducing the impact of endotoxins on insulin sensitivity and contributing to blood glucose level control.

[0056] During nighttime use, a portable blood glucose meter with wireless communication (such as Bluetooth) can be connected to the controller (if the meter does not have Bluetooth, manual recording is possible). The meter can be set to automatically measure the user's fingertip blood glucose every 1-2 hours and transmit the data to the controller for recording and analysis. During the day, blood glucose can be measured every 30 minutes to 1 hour, depending on the actual situation.

[0057] The electrical stimulation parameters can be adjusted in a timely manner based on blood glucose monitoring data and user needs. If blood glucose decreases slowly or shows no obvious downward trend, the frequency or intensity of the electrical pulses can be appropriately increased. If the user experiences mild discomfort but blood glucose shows a downward trend, the parameters can be adjusted appropriately within the user's tolerance range, or stimulation can be paused briefly before resuming control with slightly lower parameters. For example, nighttime use can be set to 6-8 hours to fully utilize the body's repair and control functions during sleep. Daytime use can be set to 30-60 minutes per session, and 1-2 daytime sessions can be performed daily depending on the user's schedule.

[0058] The controllable electrical pulse frequency range is [0, 50] GHz, and the intensity range is [0, 10] mA. By setting different parameter combinations, it can adapt to the gut microbiota control needs of different individuals, thereby affecting blood glucose levels. For example, the working mode of the electrical stimulation current: the interactive interface can set the two main parameters of the electrical pulse: frequency and intensity. According to different combinations of frequency and intensity parameters, the electrical stimulation generator produces corresponding electrical pulse currents. For example, when the frequency is set to 30 Hz and the intensity to 5 mA, the electrical stimulation generator produces a periodic electrical pulse signal with a frequency of 30 Hz and an intensity of 5 mA.

[0059] When using a portable blood glucose meter with Bluetooth connectivity, automatically measure finger-prick blood glucose every 1-2 hours at night (and every 30 minutes-1 hour during the day). If the blood glucose level drops by less than 0.5 mmol / L in three consecutive measurements, it can be considered that the blood glucose level is decreasing slowly or without a significant downward trend. In this case, the frequency of the electrical pulse can be increased by 5 Hz-10 Hz each time, or the intensity can be increased by 0.5 mA-1 mA each time. If the blood glucose level shows an upward trend in two consecutive measurements and the increase is greater than 0.3 mmol / L, the frequency can be increased by 3 Hz-8 Hz or the intensity by 0.3 mA-0.8 mA within the user's tolerance range. If the user experiences mild discomfort such as local skin tingling or slight muscle spasms and the blood glucose level shows a downward trend, the stimulation can be paused for 5-10 minutes, and then the original frequency can be reduced by 2 Hz-5 Hz and the intensity reduced by 0.5 mA-1 mA.

[0060] Through the above specific implementation methods, the electrostimulation-based blood glucose control device disclosed herein can effectively utilize the user's rest time for control, and achieve stable control of blood glucose levels by controlling the balance of intestinal flora, providing a new non-drug, non-invasive, flexible and convenient way to control blood glucose.
