Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0024] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0025] One embodiment of this utility model provides an intelligent and controllable pulsed electrical stimulation acupoint therapy device, including a power module 1, a pulse generator 2, and an acupoint stimulator 3. The pulse generator 2 includes a single pulse circuit 21, a single-use switch 22, a continuous switch 23, and a manual switch 24. The single-use switch 22 and the continuous switch 23 are arranged in parallel and are both electrically connected to the acupoint stimulator 3 through the single pulse circuit 21. The single-use switch 22 is electrically connected to the power module 1, and the continuous switch 23 is electrically connected to the power module 1 through the manual switch 24.

[0026] In this embodiment, as Figure 1 As shown, a smart and controllable pulsed electrical stimulation acupoint therapy device is constructed by a power supply module 1, a pulse generator 2, and an acupoint stimulator 3. The pulse generator 2 includes a single-pulse circuit 21, a single-use switch 22, a continuous switch 23, and a manual switch 24. The single-use switch 22 and the continuous switch 23 are connected in parallel and are both electrically connected to the acupoint stimulator 3 through the single-pulse circuit 21. The single-use switch 22 is electrically connected to the power supply module 1, and the continuous switch 23 is electrically connected to the power supply module 1 through the manual switch 24. This configuration ensures that when the continuous switch 23 is closed, the single-pulse circuit 21 and the power supply module 1 are connected, and the electrical energy... Driven by the single-pulse circuit 21, it continuously emits pulse signals to the acupoint stimulator 3, thereby generating continuous pulsed electrical stimulation through the acupoint stimulator 3. After the single-time switch 22 is closed, the operator can connect the single-pulse circuit 21 and the power module 1 by closing the manual switch 24, thereby manually realizing the output of single-pulse electrical stimulation. This allows for adjustment of the frequency of the output single-pulse electrical stimulation as needed, effectively increasing the stimulation methods of acupoint stimulation through pulsed electrical stimulation. The operator can select different stimulation methods according to different needs, thereby improving the diversity of acupoint stimulation through pulsed electrical stimulation.

[0027] Optionally, the pulse generator 2 also includes a pulse width modulator 25, which is electrically connected to the power supply module 1 and the single pulse circuit 21, respectively.

[0028] Specifically, the pulse width regulator 25 is a pulse width modulation controller (PWM), which is a technique for adjusting the width of a pulse signal. Its characteristic is that at a fixed frequency, the pulse width is changed to adjust the effective power or signal strength of the output.

[0029] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the pulse generator 2 is also equipped with a pulse width regulator 25, which is electrically connected to the power supply module 1 and the single pulse circuit 21 respectively. With this configuration, when the single pulse circuit 21 emits a pulse signal, the pulse width can be adjusted by the pulse width regulator 25, thereby changing the intensity of the pulse electrical stimulation output by the acupoint stimulator 3, and thus realizing the stimulation of acupoints in different scenarios.

[0030] For example, by adjusting the pulse width regulator 25, the single pulse circuit 21 can emit a low-voltage narrow pulse, wherein the pulse width is <2ms.

[0031] Optionally, the power module 1 includes a first power component 11, which includes a first voltage regulator 111, a first rectifier 112, and a diode 113. The first voltage regulator 111 is used to connect to low-voltage AC power and is electrically connected to the first rectifier 112. One output terminal of the first rectifier 112 is electrically connected to a continuous switch 23 through the diode 113, and the other output terminal of the first rectifier 112 is electrically connected to a manual switch 24 and a pulse width regulator 25.

[0032] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the power module 1 is configured with a first power supply component 11, which consists of a first voltage regulator 111, a first rectifier 112, and a diode 113. The first voltage regulator 111 is used to connect to low-voltage AC power and is electrically connected to the first rectifier 112, so that the connected low-voltage AC power can be adjusted by the first voltage regulator 111 and then converted into DC power by the first rectifier 112. One output terminal of the first rectifier 112 is electrically connected to the continuous switch 23 through the diode 113, and the other output terminal of the first rectifier 112 is electrically connected to the manual switch 24 and the pulse width regulator 25. With this configuration, the rectified DC power can be clipped by the diode 113 to generate a square wave signal, ensuring that a stable pulse signal can be output when the DC power is input to the single pulse circuit 21. At the same time, the rectified DC power can be input to the pulse width regulator 25, and the pulse width can be adjusted by the pulse width regulator 25, thereby changing the intensity of the pulse electrical stimulation output by the acupoint stimulator 3, and thus realizing the stimulation of acupoints in different scenarios.

[0033] For example, the first rectifier 112 is a bridge rectifier that can rectify alternating current into direct current.

[0034] Optionally, the first power supply assembly 11 further includes a counter frequency divider 114, which is connected between the diode 113 and the continuous switch 23, and is electrically connected to the circuit between the first rectifier 112 and the manual switch 24.

[0035] In this optional embodiment, in order to ensure that the current frequency of the input single-pulse circuit 21 meets the requirements, such as... Figure 1 and Figure 2 As shown, the first power supply component 11 is also provided with a counting frequency divider 114, wherein the counting frequency divider 114 is connected between the diode 113 and the continuous switch 23, and is electrically connected to the circuit between the first rectifier 112 and the manual switch 24. With this configuration, the counting frequency divider 114 can divide and count the square wave signal clipped by the diode 113, so that the single pulse circuit 21 can output a stable pulse signal.

[0036] For example, the counter divider 114 can convert a 50Hz signal to a 10Hz signal.

[0037] Optionally, the power module 1 further includes a second power component 12, which includes a MOSFET switch 121. The pulse generator 2 further includes an optocoupler 26. The single-pulse circuit 21 is electrically connected to the acupoint stimulator 3 through the optocoupler 26 and the MOSFET switch 121.

[0038] Specifically, the MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) switch 121 can control a low-voltage narrow pulse signal, and then control a high-voltage pulse signal to stimulate acupoints; the optocoupler (or opto-isolator) 26 is a device used to transmit electrical signals from one circuit to another while maintaining electrical isolation between the two circuits. This isolation can effectively prevent the propagation of noise and protect the circuit from damage caused by transient voltages.

[0039] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the power module 1 also includes a second power supply component 12, which includes a MOSFET switch 121. The pulse generator 2 also includes an optocoupler 26. The single-pulse circuit 21 can be electrically connected to the acupoint stimulator 3 through the optocoupler 26 and the MOSFET switch 121. This configuration allows for precise control of pulse transmission through the MOSFET switch 121 and electrical isolation through the optocoupler 26, ensuring the stability of the acupoint stimulator 3 during pulsed electrical stimulation.

[0040] Optionally, the second power supply assembly 12 further includes a second voltage regulator 122 and a test analog load 123. The second voltage regulator 122 is used to connect to high voltage DC power. One output terminal of the second voltage regulator 122 is electrically connected to a MOSFET switch 121. The MOSFET switch 121 is a single-pole double-throw switch for communication with the second voltage regulator 122 or the optocoupler 26. The other output terminal of the second voltage regulator 122 is electrically connected to the optocoupler 26 and the test analog load 123, respectively.

[0041] In this optional embodiment, in order to achieve control of the high-voltage pulse signal, such as... Figure 1 and Figure 2As shown, the second power supply assembly 12 is also provided with a second voltage regulator 122 and a test simulation load 123. The second voltage regulator 122 is used to connect to high voltage DC power. One output terminal of the second voltage regulator 122 is electrically connected to a MOSFET switch 121, which is a single-pole double-throw switch for communication with the second voltage regulator 122 or the optocoupler 26. The other output terminal of the second voltage regulator 122 is electrically connected to the optocoupler 26 and the test simulation load 123 respectively. This configuration allows for control of the input high-voltage DC power through the adjustment of the second voltage regulator 122, enabling the high-voltage DC power to be transmitted to the optocoupler 26 to control the formation of high-voltage pulses. These high-voltage pulses stimulate acupoints. Furthermore, since the MOSFET switch 121 is a single-pole double-throw switch, it can be connected to the second voltage regulator 122 before use, and then connected to the optocoupler 26 during use. This protects the optocoupler 26 and the single-pulse circuit 21. Additionally, the entire circuit can be tested using a simulated load 123 before use to ensure stability during subsequent use.

[0042] Optionally, the second power supply assembly 12 further includes a second rectifier 124, a capacitor 125, and a voltmeter 126. The second rectifier 124 is used to connect to high-voltage AC power and is electrically connected to the second voltage regulator 122. The two ends of the capacitor 125 and the two ends of the voltmeter 126 are respectively connected to the two output circuits of the second voltage regulator 122.

[0043] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the second power supply assembly 12 is also equipped with a second rectifier 124, a capacitor 125, and a voltmeter 126. The second rectifier 124 is used to connect to high-voltage AC power and is electrically connected to the second voltage regulator 122, thereby realizing voltage regulation and rectification of the connected high-voltage AC power. At the same time, the two ends of the capacitor 125 and the two ends of the voltmeter 126 are respectively connected to the two output circuits of the second voltage regulator 122. Not only can the capacitor 125 filter the connected current, making the rectified DC power more stable, but the voltage value in the circuit can also be obtained through the display of the voltmeter 126, which facilitates the regulation of the high-voltage DC power by the second voltage regulator 122.

[0044] Optionally, the acupoint stimulator 3 includes a single-pole multi-throw switch 31 and multiple connectors 32. The single-pole multi-throw switch 31 is electrically connected to the pulse generator 2 and is used to connect to the multiple connectors 32. The connectors 32 are used to be placed at the acupoints to be stimulated.

[0045] Specifically, connector 32 can be an electrode pad or an acupuncture needle, etc.

[0046] In this optional embodiment, a single-pole multi-throw switch 31 and multiple connectors 32 are configured to form an acupoint stimulator 3. The single-pole multi-throw switch 31 is electrically connected to the pulse generator 2 and can be connected to multiple connectors 32. The connectors 32 can be placed at the acupoints to be stimulated. With this configuration, the single-pole multi-throw switch 31 can enable pulse electrical stimulation to be output from different connectors 32, thereby stimulating acupoints at different locations.

[0047] Optionally, the intelligent and controllable pulse electrical stimulation acupoint therapy device also includes a housing 4, a power module 1 and a pulse generator 2, both located inside the housing 4, and a portion of the acupoint stimulator 3 located inside the housing 4. A touch screen 41, a stimulation switch 42 and multiple LCD screens 43 are installed on the outer wall of the housing 4, and the stimulation switch 42 is connected to a manual switch 24.

[0048] In this optional embodiment, for ease of handheld use, such as Figure 3 As shown, a housing 4 is also provided, in which the power module 1 and the pulse generator 2 are both located, while the acupoint stimulator 3 is partially located inside the housing 4. This arrangement not only ensures a stable output of pulsed electrical stimulation, but also allows the operator to move the intelligent and controllable pulsed electrical stimulation acupoint therapy device by holding the housing 4, thereby improving the ease of use of the intelligent and controllable pulsed electrical stimulation acupoint therapy device. On this basis, a touch screen 41, a stimulation switch 42, and multiple LCD screens 43 are installed on the outer wall of the housing 4. The stimulation switch 42 is connected to the manual switch 24. This arrangement allows the touch screen 41 to easily adjust the circuit inside the housing 4, while the LCD screens 43 can display the parameters of the circuit inside the housing 4. The stimulation switch 42 is connected to the manual switch 24, allowing the operator to turn the manual switch 24 on and off by pressing or toggling the stimulation switch 42.

[0049] Optionally, the intelligent and controllable pulse electrical stimulation acupoint therapy device also includes a control module. The control module is electrically connected to the pulse generator 2, the touch screen 41, and the LCD screen 43, respectively. The control module stores working parameters so that the pulse generator 2 can drive the acupoint stimulator 3 according to the working parameters. The touch screen 41 is used to retrieve the working parameters, and the LCD screen 43 is used to display the working parameters.

[0050] In this optional embodiment, in order to facilitate the automated control of the intelligent and controllable pulse electrical stimulation acupoint therapy device, a control module is also provided. The control module is electrically connected to the pulse generator 2, the touch screen 41, and the liquid crystal display 43, respectively. The control module stores working parameters, which can be used by the pulse generator 2 to drive the acupoint stimulator 3 according to the working parameters. The touch screen 41 can retrieve the working parameters and then transmit the working parameters to the pulse generator 2 to realize the control of the acupoint stimulator 3. The liquid crystal display 43 can display the working parameters for easy observation by the operator.

[0051] For example, the working parameters can be at least one of acupoint type, frequency, pulse width, and intensity.

[0052] For example, in this utility model, such as Figure 2 As shown, a 220VAC (50Hz) mains power supply is isolated, rectified, and filtered (first power supply component 11) to be converted into high-voltage, adjustable-intensity DC power as the source of the electrical stimulation pulse signal. Its output is switched on / off by a MOSFET switch 121 to the acupoint. Another mains power supply (50Hz) is rectified, clipped, counted, and divided (second power supply component 12) to finally generate a 10Hz, small-amplitude continuous pulse signal (period 100m). This continuous pulse signal triggers a single-pulse generation circuit to generate a continuous low-voltage narrow pulse (pulse width <2ms, adjustable). The on / off state of the MOSFET switch 121 is controlled by this continuous narrow pulse. An optocoupler 26 is used for isolation. The switch can also be switched to manual mode to generate a single narrow pulse to control the generation of a single high-voltage pulse to stimulate the acupoint. The stimulation intensity can be adjusted by adjusting the amplitude of the high-voltage pulse or the width of the low-voltage pulse to adapt to different human tolerance levels.
