[0002] The low-frequency therapeutic device uses a wave frequency range of 0 to 1000 Hz. It can only stimulate the sensory nerves of the epidermis. Its working principle is: electrodes are attached to the painful area, and low-frequency current is input to affect the pain nerves, thereby affecting the body's function of transmitting pain, so that it is difficult for the brain to receive the pain information transmitted by the nerves.

[0003] The therapeutic mechanism is as follows: ① Balance the body's bioelectric charge: The intercellular matrix is ​​the main pathway for bioelectricity between cells and the basis for cells to generate action potentials. The imbalance of intercellular matrix charge will affect the conduction of action potential electrical signals between cells, and then affect the generation and flow of bioelectricity in the body's organs and affect the function of tissues and organs. The intercellular matrix is ​​equivalent to the capacitor in the circuit. It is not only part of the bioelectric current running channel, but also plays a role in regulating bioelectricity. Our bioelectric resonance treatment technology is to apply an external voltage to balance the positive and negative charges outside the cell and the positive and negative charges inside the cell, and generate bioelectric resonance. ② Correct the bioelectric laws of the human body: The bioelectric laws of different people are different. The bioelectric laws include the frequency, intensity, waveform, etc. of bioelectricity.

[0004] With the development of electronic technology, existing low-frequency therapeutic devices treat diseases such as pain by synthesizing modulated pulses of different waveforms, including changing the pulse width and the shape of the leading and trailing edges of the pulse to simulate different action effects.

[0005] However, the existing low-frequency therapeutic devices still have single functions and are not good in preventing or delaying disuse atrophy of lower limb muscles, enhancing muscle performance, muscle retraining, and restoring muscle motor function. Utility Model Content

[0006] The existing low-frequency therapeutic apparatus has a single function, resulting in poor performance and short service life in treating lower limb muscle diseases.

[0007] In view of the above problems, a multifunctional venous circulation improver is proposed. By making the waveform control module output a first waveform with specified parameters, it can be effectively used to prevent or delay disuse atrophy, enhance muscle performance, muscle retraining, and restore muscle motor function. It can also output a second waveform and a third waveform with specified parameters to effectively improve the blood circulation of the lower limb veins, reduce lower limb swelling and local muscle soreness. The three waveforms are used alternately to improve the treatment effect. By setting a protection unit in the waveform control module, the residual voltage in the electronic components of the boost unit and the output unit can be quickly released after stopping the output or working, which is beneficial to improving the patient experience and increasing the life of the electronic components.

By making the waveform control module 130 output the first waveform of the specified parameters, it can be effectively used to prevent or delay disuse atrophy, enhance muscle performance, muscle retraining, and restore muscle motor function. The second waveform and the third waveform of the specified parameters can also be output to effectively improve the blood circulation of the lower limb veins, reduce lower limb swelling and local muscle soreness. The three waveforms are used alternately, which is beneficial to improve the treatment effect. By setting the protection unit 135 in the waveform control module 130, after stopping the output or working, the residual voltage in the electronic components of the boost unit 131 and the output unit 133 is quickly released, which is beneficial to improve the life of the electronic components.

[0085] It can be understood that as an electronic device, it must have basic functional components, such as a power management module and a battery.

[0086] It can also be understood that, for the purpose of interaction, a display module may also be included, such as an LED screen, an LCD screen, etc.

[0087] In this embodiment, the MCU module 120 controls the waveform control module 130 to output the first waveform, which can effectively prevent or delay disuse atrophy, enhance muscle performance, retrain muscles, and restore muscle motor function.

[0088] It is worth noting that, in some implementations, the waveform control module 130 may also output multiple waveforms, such as one or more of the second waveform and the third waveform, which also falls within the protection scope of the present application.

After a certain period of time, the multifunctional venous circulation improver is controlled to stop working. The MCU module 120 controls the switch of the boost unit 131 according to the feedback of the working voltage signal of the boost unit 131 by the feedback unit 132 to maintain the stability of the output of the boost unit 131.

[0095] Furthermore, if Figure 3 , Figure 3 This is a schematic diagram of the connection of the electronic components of the waveform control module; the electronic components of the boost unit 131 are composed of:

[0099] The working principle of the boost unit 131 is:

[0100] A square wave with a certain pulse width and frequency is input to the PWM end, and the on and off of the first transistor Q is controlled by controlling the duty cycle. After the first transistor Q1 is turned on, the second capacitor C2 (energy storage capacitor) is charged to generate a voltage several times higher than the input power supply. The boost value is controlled by controlling the pulse width of the above square wave, thereby controlling the intensity of treatment.

[0101] Furthermore, the electronic components of the output unit 133 are composed of:

[0102] The first input terminal, the third resistor R3, the second transistor Q2, the fourth resistor R4, and the fifth resistor R5.

[0103] The second input terminal, the sixth resistor R6, the third transistor Q3, the seventh resistor R7, and the eighth resistor R8.

[0104] The fourth transistor Q4, the fifth transistor Q5, the sixth transistor Q6, and the seventh transistor Q7.

[0105] A ninth resistor R9, a tenth resistor R10, and an output electrode OUT.

[0106] The first input terminal, the third resistor R3, the second transistor Q2, the fourth resistor R4, and the fifth resistor R5 form a first input circuit.

[0107] The second input terminal, the sixth resistor R6, the third transistor Q3, the seventh resistor R7, and the eighth resistor R8 form a second input circuit.

[0108] The fourth transistor Q4, the fifth transistor Q5, the sixth transistor Q6 and the seventh transistor Q7 form an H-bridge circuit.

[0109] The first input circuit inputs a square wave signal in a first direction through an H-bridge circuit.

[0110] The first input circuit inputs a square wave signal in the second direction through an H-bridge circuit.

[0111] The phase difference between the square wave signal in the first direction and the square wave signal in the second direction is 180 degrees.

[0112] Its circuit structure is:

[0113] The first input terminal is electrically connected to a first terminal of the third resistor R3 , a second terminal of the third resistor R3 is electrically connected to a base of the second transistor Q2 , and an emitter of the second transistor Q2 is grounded.

[0114] The collector of the second transistor Q2 is electrically connected to the first end of the fourth resistor R4 and the first end of the fifth resistor R5, the second end of the fourth resistor R4 is electrically connected to the second end of the ninth resistor R9 and the base of the fourth transistor Q4, and the second end of the fifth resistor R5 is electrically connected to the base of the sixth transistor Q6.

[0121] The working principle of the output unit 133 is as follows: the MCU module 120 transmits waveform signals to the base of the second transistor Q2 and the base of the third transistor Q3 respectively. The high-level signal in the waveform signal turns on the second transistor Q2 and the third transistor Q3 respectively. Since the emitter of the second transistor Q2 and the emitter of the third transistor Q3 are grounded, the low-level signal controls the fourth transistor Q4, the fifth transistor Q5, the sixth transistor Q6, and the seventh transistor Q7 in the H-bridge to turn on. After turning on, the boosted working current flows from the emitter to the collector to perform treatment. The MCU module 120 controls the on and off of the fourth transistor Q4, the fifth transistor Q5, the sixth transistor Q6, and the seventh transistor Q7 through the first waveform, the second waveform, and the third waveform to simulate various treatment techniques.

[0122] The phase difference between the square wave signal in the first direction and the square wave signal in the second direction is 180 degrees, that is, when the first input circuit is working, the fourth transistor Q4 and the sixth transistor Q6 are turned on to output the treatment waveform. After reversing, the second input circuit is working, the fifth transistor Q5 and the seventh transistor Q7 are turned on to output the treatment waveform.
