Description

Technical Field

[0001] This invention relates to the technical field of health care medical devices, and in particular to a dual-effect physiotherapy method and system combining ultrasound and water acupuncture. Background Technology

[0002] With the increasing demand for health and wellness among modern people and the pressures of a fast-paced lifestyle, foot baths have emerged. Combining traditional Chinese medicine foot therapy theory with modern technology, these devices utilize constant temperature heating, bubble massage, and infrared stimulation to precisely target over 60 acupoints on the soles of the feet, solving the problems of time-consuming, laborious, and inaccurate acupoint location associated with traditional manual massage. In actual use, continuous soaking in warm water at around 40℃ dilates capillaries and accelerates metabolism; the dual stimulation of rollers and bubbles relieves foot fatigue and improves sleep quality; and the targeted design for key acupoints such as Yongquan and Taichong further helps regulate blood pressure and relieve joint pain. Data shows that among regular users of foot baths, 78% reported improvement in symptoms of cold hands and feet, and 65% reported shorter sleep onset times. Their convenience and significant effects make them a popular choice for family health management.

[0003] Based on this, Chinese patent document CN115349767B discloses a foot bath device, comprising: a base, a basin body assembled on the base, a controller disposed within the base, and a lifting mechanism including a lifting device and an enclosure assembly connected to the base. The lifting device is connected to the basin body and electrically connected to the controller. The lifting device can move up and down relative to the enclosure assembly along the height direction of the basin body, causing the basin body to unfold or fold relative to the base. At least one set of detection components includes a switch and an actuating element. The switch is electrically connected to the controller and is disposed in one of the enclosure assembly and the lifting device, while the actuating element is disposed in the other. The switch or actuating element disposed on the lifting device moves synchronously with the lifting device and can contact the actuating element or switch disposed on the enclosure assembly during movement; after receiving a trigger signal, the controller controls the lifting device to stop moving. This foot bath device can automatically and accurately control the position of the product when unfolding or folding, reducing the risk of product damage and improving the user experience.

[0004] Furthermore, another Chinese patent document, CN205814659U, discloses a water acupuncture foot bath machine, which includes a basin, a lid, foot pads, a control panel, and a drain pipe. The lid is installed on the basin, and the foot pads consist of two pieces located on the inner bottom of the basin, with a water inlet in the middle of the two foot pads. The control panel is located at the front of the outer wall of the basin, and a drain pipe is located at the rear of the basin. The foot pads also include an acupuncture device and several massage heads. This water acupuncture foot bath machine features a three-level vibration massage function; the strong vibration enhances blood circulation in the feet. It can accelerate foot metabolism, regulate blood pressure, reduce blood viscosity, quickly eliminate fatigue, and improve the body's immunity. The circulating spray of water makes the temperature inside the basin more uniform, increases the oxygen content in the water, produces active water characteristics, and accelerates the metabolism of the skin surface. It has a good cleansing effect on the foot skin. The acupuncture function makes the foot bath more comfortable and enhances blood circulation.

[0005] However, existing foot bath devices suffer from a lack of functionality. Specifically, the core principle of traditional roller massage foot baths is to apply physical stimulation to the soles of the feet using mechanical rollers, targeting over 60 reflex zones and acupoints. The rollers compress the skin and muscle layers of the soles through rotation or rolling, similar to acupressure, which can break down muscle adhesions and fascial tension, directly relieving foot fatigue and soreness. However, high-intensity or prolonged massage can easily lead to redness, abrasions, or bruising on the soles of the feet, and in severe cases, may cause chronic strain or even plantar fasciitis, especially posing a higher risk to people with sensitive skin. Furthermore, excessive massage pressure or duration may overstimulate the nerves and muscles of the feet, causing pain, numbness, or localized edema, affecting blood circulation and comfort. In addition, current massage foot bath devices primarily focus on massaging the soles of the feet, neglecting the removal of dead skin and other debris.

[0006] Furthermore, while existing technologies also disclose a foot massager that combines electro-pulse water acupuncture, which can simulate the effects of acupuncture through electrical stimulation in water, this technology has the following limitations: electro-pulse stimulation poses safety risks, especially for those with sensitive skin or heart conditions; and its function is limited, lacking deep cleaning and sterilization capabilities.

[0007] Therefore, although traditional ultrasonic foot bath devices have cleaning and sterilization functions, they lack precise water stimulation of acupoints on the feet, making it difficult to achieve the synergistic effect of "unblocking meridians and activating collaterals" in traditional Chinese medicine theory. Summary of the Invention

[0008] Therefore, it is necessary to provide a dual-effect physiotherapy method and system that combines ultrasound and hydroacupuncture to address the shortcomings of existing technologies.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A dual-effect physiotherapy method combining ultrasound and water acupuncture includes the following core steps: Mode selection and parameter calling steps: Receive the working mode selection command issued by the user through the input module; Based on the command, call the corresponding ultrasonic drive parameter set from the pre-stored parameter library; The working modes include at least a cleaning mode with continuous ultrasonic output and a water acupuncture mode with pulse-modulated ultrasonic output.

[0010] Ultrasonic output execution steps: Based on the invoked ultrasonic drive parameter set, drive the ultrasonic transducer array in the physiotherapy device to emit the corresponding ultrasonic sequence to the liquid medium contained in the physiotherapy tank.

[0011] Safety monitoring steps: Real-time monitoring of water level and temperature in the physiotherapy tank. When the monitoring data exceeds the preset safety range, the ultrasonic output is automatically interrupted and an alarm is issued.

[0012] As a further improvement to the first aspect of the technical solution, the water acupuncture mode is specifically configured to simulate various basic techniques of traditional Chinese medicine acupuncture, including: Simulated insertion method: By controlling one or more transducers corresponding to the target acupoint, short-duration, high-power ultrasonic pulses are emitted, for example, with a frequency of 1.0~1.2 MHz, a pulse width of 10~50 ms, and a power of 50~70 W, a transient acoustic radiation force in the vertical direction is generated to simulate the stimulation of obtaining qi when the needle is quickly inserted.

[0013] Simulation method: By controlling the transducer corresponding to the target acupoint, long-duration, low-power ultrasonic pulses are emitted, for example, with a frequency of 800~900 kHz, a pulse width of 100~200 ms, and a power of 20~35 W. The negative pressure attraction effect generated by the microfluidic cavitation effect during the pulse interval is used to simulate the pulling sensation of the needle body being lifted.

[0014] Simulated twisting technique: By controlling multiple transducers around the target acupoint, they are sequentially excited in a preset clockwise or counterclockwise order with a millisecond delay. Each transducer emits a short pulse, thereby generating a rotating sound field and shear force in the water, simulating the tangential mechanical stimulation of the needle twisting.

[0015] Simulated Rotation Method: Based on the aforementioned twisting method, frequency sweeping and power gradual modulation are combined to cause periodic changes in the penetration depth and deposition location of sound wave energy in the tissue, simulating the complex techniques of acupuncturists rotating the needle to change the force and depth, thus achieving three-dimensional unblocking.

[0016] As a further improvement to the first aspect of the technical solution, the working mode also includes a collaborative mode. In this mode, the system alternately executes the cleaning mode and the water acupuncture mode according to a preset time sequence. A preferred collaborative process is: first run the cleaning mode for 5-10 minutes, then run the water acupuncture mode for 5-10 minutes, repeating this cycle 2-3 times. This process realizes the therapeutic logic of "cleansing before unblocking," creating better conditions for subsequent acupoint stimulation through cleaning, thereby producing a synergistic effect.

[0017] In a second aspect, the present invention provides a dual-effect physiotherapy system combining ultrasound and hydroacupuncture for performing the above-described method, comprising: Physiotherapy container unit: includes a physiotherapy liner for containing a liquid medium and for immersing the feet in it.

[0018] Ultrasonic actuator: includes an array of ultrasonic transducers disposed at the bottom of the physiotherapy bladder, the array being composed of multiple transducers that can be controlled independently or in groups.

[0019] Intelligent control unit: As the core of the system, it includes a main controller and a memory electrically connected to it; the memory pre-stores ultrasonic drive parameter sets corresponding to various working modes including the cleaning mode, water acupuncture mode and collaborative mode; the main controller is configured to: respond to user commands, call the corresponding parameter set, and generate high-precision drive signals to control the output of the ultrasonic execution unit.

[0020] Mapping and Focusing Module: As part of the intelligent control unit, it maps the physical layout of the ultrasonic transducer array to a pre-stored digital map of acupoints on the sole of the foot, enabling the main controller to focus energy output on key acupoints such as Yongquan and Taichong by controlling transducers at specific locations.

[0021] Compared with the prior art, the technical solution provided by the present invention has the following significant advantages: 1. It has pioneered a new path for bionic mechanical acupuncture: For the first time, it uses controllable pulsed ultrasound to physically and accurately simulate traditional Chinese medicine acupuncture techniques such as lifting, inserting, twisting, and rotating, achieving a leap from electrical stimulation to bionic mechanical stimulation. This is more in line with traditional Chinese medicine theory, has a more advanced physiotherapy mechanism, and provides a user experience that is closer to real acupuncture.

[0022] 2. Achieved true functional synergy and integration: Through method design and system control, the originally independent ultrasonic cleaning and water acupuncture physiotherapy functions are deeply integrated in a single physical field and a single device, and can execute an intelligent synergistic mode, producing a physiotherapy effect of 1+1>2.

[0023] 3. Significantly improved safety and applicability: Stimulation is achieved entirely using mechanical waves, fundamentally eliminating the safety risks associated with electrical pulses, making it safe and comfortable for a wider range of people, including those with sensitive skin and heart conditions.

[0024] 4. Provides precise and personalized physiotherapy solutions: Through transducer arrays and acupoint mapping, precise energy delivery is achieved; through programmable parameter sets, users can flexibly adjust the stimulation intensity and mode according to their own feelings and needs, realizing a personalized physiotherapy experience.

[0025] 5. Significant therapeutic effects: The specific mechanical field generated by the method described in this invention and the superior physiological effects it induces, such as significantly improving local blood flow and significant clinical efficacy, such as effectively relieving plantar fasciitis pain, have all been quantitatively verified through mechanical measurements and clinical trials, demonstrating significant therapeutic effects.

[0033] Please refer to the following: Figures 1 to 9 The present invention first provides one embodiment of a dual-effect physiotherapy device combining ultrasound and water acupuncture, which includes: The device comprises a main body 1, a physiotherapy device inner liner 2, an ultrasound and water acupuncture generating module 3, a temperature control module 4, an opening and closing cover 5, and an input / output control module 6. The physiotherapy device inner liner 2 is housed within the inner cavity of the main body 1. The ultrasound and water acupuncture generating module 3 is connected below the physiotherapy device inner liner 2 and is positioned between the bottom of the inner cavity of the main body 1 and the bottom of the physiotherapy device inner liner 2. The temperature control module 4 is positioned at the bottom of the physiotherapy device inner liner 2. The opening and closing cover 5 is movably mounted on the main body 1 and the physiotherapy device inner liner 2. The input / output control module 6 is located on the upper part of the main body 1 and is connected to the ultrasound and water acupuncture generating module 3 and the temperature control module 4, respectively.

[0034] Specifically, the main body 1 serves functions such as support and decoration. The inner liner 2 of the physiotherapy device, located within its cavity, can be integrated with the main body 1 or can be lifted and separated separately. The inner liner 2 primarily functions to store and contain liquid media, such as warm water or medicinal solutions, so that users can place their feet or other body parts into the inner liner 2 and immerse them in the liquid media, preparing them for the subsequent physiotherapy process.

[0035] Furthermore, the ultrasonic and water acupuncture generating module 3 includes a support frame 301, a main control circuit board 302, an ultrasonic signal generator 303, and several ultrasonic transducers 304. The support frame 301 is located at the bottom of the inner cavity of the main body 1, and the main control circuit board 302 is connected to the support frame 301. The ultrasonic signal generator 303 is integrated into the main control circuit board 302. Several ultrasonic transducers 304 are evenly distributed at the bottom of the inner liner 2 of the physiotherapy device, and the ultrasonic signal generator 303 is controlled and connected to each of the ultrasonic transducers 304. The input / output control module 6 is electrically connected to the main control circuit board 302.

[0036] Specifically, the main control circuit board 302 integrates necessary electronic control components, such as a main controller, a power management module, a drive control circuit for an ultrasonic signal generator, a power drive amplification module, an impedance matching network / LC matching network, and a protection and detection module. After receiving the control signal input by the user from the input / output control module 6, the main control circuit board 302 can transmit the corresponding control signal to the ultrasonic signal generator 303, and the ultrasonic transducer 304 couples the energy of the ultrasonic waves into the water or other liquid medium in the inner tank 2 of the physiotherapy device.

[0037] Furthermore, the temperature control module 4 has a heating element 401 and a temperature control circuit board 402; the heating element 401 is connected to the bottom of the inner liner 2 of the physiotherapy device, and the temperature control circuit board 402 is disposed on the bottom of the inner cavity of the main body 1, and the temperature control circuit board 402 is electrically connected to the input / output control module 6.

[0038] Furthermore, a support bracket 7 is provided within the inner liner 2 of the physiotherapy device. The support bracket 7 has a support frame 701 and a support mesh 702. The support frame 701 is fitted into the inner liner 2 of the physiotherapy device, and the support mesh 702 is disposed on the support frame 701. Specifically, when a user places their feet or other objects into the inner liner 2 of the physiotherapy device, the support bracket 7 can lift the user's feet, preventing the user's feet from directly contacting the bottom of the inner liner 2. The support mesh 702 facilitates the flow and penetration of water.

[0039] Furthermore, the input / output control module 6 includes a housing 601, a control circuit board 602, a speaker unit 603, an input unit 604, and a display unit 605. The housing 601 is mounted on the main body 1, and the control circuit board 602 is housed within the housing 601. The speaker unit 603 is housed within the housing 601, the input unit 604 is mounted on the housing 601, and the display unit 605 is mounted on the housing 601 adjacent to the input unit 604. Specifically, the control circuit board 602 is electrically connected to the speaker unit 603, the input unit 604, and the display unit 605. The speaker unit 603 can emit sound prompts to facilitate interaction with the user. The input unit 604 can be an input component such as a button or a touchscreen. The display unit 605 can be a display screen or other display component used to display the device's operating information or input / output information.

[0040] In the above embodiment, when the ultrasonic and water acupuncture generating module 3 is working, the ultrasonic energy generated by the ultrasonic transducer 304 propagates in the liquid medium within the inner liner 2 of the physiotherapy device, achieving deep cleaning, sterilization, and basic massage functions through cavitation effect. The user selects a working mode, such as cleaning mode or massage mode, via the input / output control module 6, and the device executes the corresponding ultrasonic output. The temperature control module 4 maintains the liquid medium at a suitable temperature, such as around 40°C, to enhance the therapeutic effect.

[0041] Furthermore, based on the above-described implementation method, the control method of the ultrasonic and water acupuncture generation module 3 is further optimized so that it can achieve the dual-effect physiotherapy function of ultrasonic cleaning and water acupuncture stimulation.

[0042] The ultrasonic and water acupuncture generating module 3 is configured to support multiple programmable operating modes, including a cleaning mode, a water acupuncture mode, and a collaborative mode. These modes are implemented through a control program integrated into the main control circuit board 302, as detailed below: Cleaning mode: Continuous ultrasonic output with a frequency range of 1.0–1.5MHz and a power of medium to high, such as 60–90W, is used to achieve deep cleaning, sterilization and softening of cuticles.

[0043] Water acupuncture mode: It uses pulse-modulated ultrasound output with a frequency range of 800kHz–1.2MHz, an adjustable pulse frequency of 1–10Hz, and a low to medium power, such as 30–60W, to simulate the "lifting, inserting, twisting, and rotating" techniques of water acupuncture, providing precise mechanical stimulation to acupoints on the soles of the feet, promoting blood circulation and acupoint activation.

[0044] Synergistic Mode: Alternates between cleaning mode and hydroacupuncture mode according to a preset time sequence. For example, it first runs in cleaning mode for 5–10 minutes, then automatically switches to hydroacupuncture mode for 5–10 minutes, and repeats this cycle to achieve synergistic effects between cleaning and physical therapy.

[0045] The layout of the ultrasonic transducer 304 corresponds to the acupoint map of the human foot, such as Yongquan (KI1), Taichong (LR3), and Zusanli (ST36). By controlling the switching state and output parameters of different transducers, such as frequency, power, and pulse timing, regional enhanced stimulation can be achieved, and focused energy output can be applied to specific acupoints.

[0046] The display unit 605 of the input / output control module 6 provides a graphical mode selection interface, allowing users to select the working mode, adjust the intensity level, and set the timer via the input unit 604. The control circuit board 602, based on user input, calls preset parameters to control the output of the ultrasonic signal generator 303 and provides voice prompts through the speaker unit 603.

[0047] Please refer to the following: Figures 5 to 9 Based on the aforementioned hardware structure, the present invention provides a dual-effect physiotherapy device combining ultrasound and water acupuncture, which, through its built-in intelligent control system, achieves the following physiotherapy methods: 1. After the system starts, it performs initialization self-test and water level safety detection, which can be achieved through a water level sensor.

[0048] 2. After the user selects a mode, the controller loads the corresponding parameter set.

[0049] 3. Execution Mode: In collaborative mode, first run the cleaning mode, such as 1.2MHz continuous wave for 5 minutes, then run the water acupuncture mode, such as 800kHz pulse wave at 5Hz for 8 minutes.

[0050] 3. Real-time safety monitoring: Continuously monitors water temperature and level, and automatically shuts down and alarms if any abnormality is detected.

[0051] 4. After the mode ends, the system returns to standby mode.

[0052] Through the above control strategy, this embodiment 2 achieves the dual functions of cleaning and sterilization and acupoint stimulation with a single ultrasound module, thereby improving the physiotherapy effect and user experience.

[0053] Furthermore, the present invention provides another embodiment of the dual-effect ultrasound and water acupuncture therapy device, which is provided with a handle 8, which is movably connected to the main body 1. Specifically, the handle 8 can rotate freely along its connection with the main body 1, thereby facilitating the handle 8 to enter or exit the storage state, so that the user can lift and move the entire dual-effect ultrasound and water acupuncture therapy device of the present invention to other locations using the handle 8.

[0054] Furthermore, a power module 9 is provided on the side of the main body 1. The power module 9 has a mounting base 901, a socket 902, and a power switch 903. The mounting base 901 is located on the lower part of one side of the main body 1, the socket 902 is located in the mounting base 901, and the power switch 903 is located adjacent to the socket 902 in the mounting base 901. The power switch 903 is electrically connected to the main control circuit board 302, the temperature control circuit board 402, and the control circuit board 602. The socket 902 is connected to an external power source. Thus, the user can quickly power on or cut off the entire device by pressing the power switch 903.

[0055] Furthermore, the bottom of the main body 1 is provided with mounting grooves 101 and anti-slip pads 102; a plurality of mounting grooves 101 are evenly distributed on the bottom of the main body 1, and each mounting groove 101 is provided with an anti-slip pad 102. Specifically, the anti-slip pad 102 can be made of rubber, silicone or plastic, etc., and the anti-slip pad 102 has the functions of anti-slip, shock absorption and noise reduction. When the main body 1 is placed on the ground, it can increase the friction between the main body 1 and the ground.

[0056] Furthermore, a heat dissipation grille 10 is provided at the bottom of the main body 1, and the temperature control circuit board 402 and the main control circuit board 302 are provided above the heat dissipation grille 10; the ultrasonic transducer 304 is positioned opposite the heat dissipation grille 10. Specifically, the heat dissipation grille 10 facilitates gas exchange between the air inside the main body 1 and the external environment, thereby removing the heat generated inside the main body 1 during the operation of various components; ensuring the stability of the device during long-term operation.

[0057] Furthermore, in the existing technology, foot therapy devices combined with aquatic environments are mainly divided into two categories: one is a massage foot bath device using mechanical rollers, which has problems such as easy skin damage and limited stimulation techniques; the other is a water acupuncture foot therapy machine using electrical pulse stimulation. Although it attempts to simulate acupuncture, its mechanism of action is electrophysiological stimulation, which has contraindications, such as being unsafe for pacemaker users and people with sensitive skin. Moreover, it cannot realize the rich mechanical techniques of traditional Chinese medicine acupuncture such as "lifting, inserting, twisting, and rotating," and the user experience is far from that of real acupuncture.

[0058] Ultrasonic technology has been used in the cleaning function of foot baths, but its working mode is usually a single continuous wave with diffused energy, which can only achieve surface cleaning and basic massage, and cannot focus on and provide precise biomimetic stimulation of acupoints on the soles of the feet.

[0059] Therefore, the present invention further provides a physiotherapy method using the aforementioned dual-effect physiotherapy device of ultrasound and water acupuncture. The core of this method is: by precisely controlling the timing, phase, frequency and intensity parameters of pulsed ultrasound, a specific mechanical vector field is generated in the liquid medium to physically simulate the basic techniques of "lifting, inserting, twisting and rotating" in traditional Chinese medicine acupuncture, and to perform non-invasive biomimetic mechanical stimulation on the acupoints on the soles of the feet.

[0060] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments. Example 1: System Structure and Basic Control The hardware foundation of the aforementioned dual-effect ultrasound and water acupuncture therapy method can be based on the dual-effect ultrasound and water acupuncture therapy device described above. Its core lies in the main controller, which has pre-stored drive logic and parameter libraries for implementing different acupuncture techniques and can independently and precisely control the bottom ultrasound transducer array. The layout of the transducer array is associated with the spatial location of acupoints on the soles of the feet, such as Yongquan and Taichong, forming a digital acupoint map.

[0061] Example 2: Specific Implementation of the Simulated "Insertion" Method The "insertion" method is designed to generate rapid, deep vertical stimulation.

[0062] Drive parameters: Control one or more transducers corresponding to the target acupoint to emit one or more short pulses with a frequency of 1.0MHz-1.2MHz, a pulse width of 10ms-50ms, and a power of 50W-70W. The pulse repetition frequency can be set to 0.5Hz-1Hz as needed.

[0063] Mechanism of action: This parameter combination generates transient high-intensity acoustic pulses in water, forming a powerful acoustic radiation force, like an invisible miniature striking pin, creating a rapid, vertical "compression-release" mechanical stimulation on the skin and subcutaneous tissue at a depth of 2-5mm at acupoints. This instantaneous high pressure can effectively activate deep mechanoreceptors, such as lamina rings, simulating the distending pain sensation of "deqi" in manual acupuncture.

[0064] Application scenarios: Used at the beginning of physiotherapy to activate acupoint sensation or to provide strong stimulation for specific pain conditions.

[0065] Example 3: Specific Implementation of the Simulated "Lifting" Method The "lifting" technique is designed to create a soothing, upward pulling sensation.

[0066] Drive parameters: Use a slightly lower frequency of 800kHz-900kHz, a longer pulse width of 100ms-200ms, and a lower power of 20W-35W. Set the pulse repetition frequency to 1Hz-2Hz.

[0067] Mechanism of action: The longer pulse width and specific frequency are conducive to generating a more pronounced cavitation effect microfluidic flow at the tissue-media interface. During the pulse interval, the microfluidic flow generates a slight "negative pressure attraction" effect, causing the surface tissue to have an upward mechanical tendency to be "pulled", thus sensorily simulating the lifting action of the "lifting" method.

[0068] Application scenarios: Often combined with the "insertion" method to form a "one-insertion-one-lift" stimulation cycle, used to soothe muscles and tendons and regulate the stimulation rhythm.

[0069] Example 4: Specific Implementation of the Simulated "Twisting" Method The "twisting" method is designed to generate rotational, tangential shear stimuli.

[0070] Driving parameters: Centered on an acupoint, control 4-6 transducers arranged in a ring around it. Each transducer emits a short pulse with a frequency of 900kHz-1.1MHz and a power of 30W-45W, with a pulse width of 20-40ms. Crucially, these transducers are activated sequentially in a clockwise or counterclockwise order with a millisecond-level delay; for example, each transducer is set to an interval of 3ms-8ms.

[0071] Mechanism of action: This ring-shaped delayed excitation mode generates a rotating sound field in the water. When this sound field acts on the acupoint tissue, it forms a cyclic shear force field, which sequentially and tangentially mechanically stimulates different sides of the acupoint, thereby producing a unique sensation similar to the gentle "twisting" of a needle.

[0072] Application scenarios: Used to expand the stimulation range of a single acupoint, enhance the "deqi" sensation, and promote local blood circulation.

[0073] Example 5: Specific Implementation of the Simulated "Transformation" Method The "rotation" method is an enhancement and deepening of the "twisting" method, simulating a large-amplitude rotation.

[0074] Driving parameters: While performing the ring-sequential excitation as described in Example 4, the frequency of each excitation pulse is swept slowly between 800 kHz and 1.2 MHz, while its power is synchronously modulated slowly within the range of 25 W to 50 W. A complete "turn" cycle can last for 1-3 seconds.

[0075] Mechanism of action: Frequency sweeping causes periodic changes in the penetration depth and energy deposition location of sound waves in tissues. Combined with gradual power variation, this composite modulation simulates the complex "techniques" of subtle changes in force and depth when an acupuncturist rotates the needle. It can provide comprehensive and three-dimensional stimulation to different tissue layers in the acupoint area from superficial to deep, resulting in a stronger effect of unblocking meridians.

[0076] Application scenario: Used to deal with severe meridian blockage or intractable pain.

[0077] Example 6: Application of the Collaborative Physiotherapy Mode This invention can preset multiple collaborative modes, such as a "cleaning-water acupuncture collaborative mode": The system first runs in cleaning mode: all or most of the transducers emit continuous ultrasonic waves at a frequency of 1.2MHz and a power of 70W for 5-10 minutes to achieve deep cleaning, sterilization and softening of the feet.

[0078] The system then automatically switches to the water acupuncture mode: according to the preset plan, such as for Yongquan acupoint and Taichong acupoint, the system sequentially performs the manipulation simulation in Examples 2 to 5, with a total duration of 10-15 minutes.

[0079] This synergistic mode is repeated cyclically, with each treatment lasting 20-30 minutes. This mode implements the therapeutic logic of "cleansing first, then unblocking," as a cleansed foot is more conducive to the transmission and absorption of energy from acupoint stimulation.

[0080] To verify the effectiveness of the physiotherapy method demonstrated in this invention, the present invention further discloses the following experiments: Experiment Example 1: Verification of Mechanical Effects Methods and apparatus: Using a miniature hydrophone in a tissue-simulating phantom, the acoustic field pressure generated when simulating the "insertion" and "twist" methods of the present invention was measured.

[0081] result: When simulating the "insertion" method, the peak transient sound pressure in the vertical direction was measured to be >0.5MPa, which is sufficient to produce effective mechanical stimulation to the subcutaneous tissue.

[0082] When simulating the "twisting" method, the tangential shear stress was measured to be >0.15 kPa, and a significant sound field rotation phenomenon was observed.

[0083] Conclusion: Experimental data confirm that the method of the present invention can generate a quantifiable specific mechanical field corresponding to a specific acupuncture technique, rather than a simple uniform vibration.

[0084] Experiment Example 2: Verification of Physiological Effects Methods and Design: Thirty healthy volunteers were recruited and divided into two groups. The experimental group received stimulation of the Yongquan acupoint using the "insertion" method of this invention, with the same parameters as in Example 2 above. The control group received traditional electro-pulse water acupuncture stimulation. Local blood flow changes before and after stimulation were monitored using a laser Doppler flowmeter.

[0085] result: After stimulation, the local blood perfusion volume in the experimental group increased by an average of (48.5±8.7)%.

[0086] The average increase in blood perfusion in the control group was (25.3±6.2)%.

[0087] The difference between the two groups was statistically significant, i.e., p < 0.01.

[0088] Therefore, it can be seen that the local blood flow enhancement effect induced by the mechanical stimulation of pulsed ultrasound in this invention is significantly better than that of traditional electrical pulse stimulation, indicating that its mechanism of action and physiological effects are superior.

[0089] Experiment Example 3: Verification of Subjective Efficacy and Safety Methods and Design: A 4-week clinical observation was conducted on 60 patients with mild to moderate plantar fasciitis. Patients were randomly assigned to either the treatment group of this invention or the traditional massage group, with a synergistic approach used in the treatment group. The Visual Analogue Scale (VAS) was used to assess pain, and adverse reactions were recorded.

[0090] result: VAS score: After treatment, the VAS score of the invention group decreased by an average of (4.7±0.9) points, while that of the traditional massage group decreased by an average of (2.6±0.8) points.

[0091] Safety: In the entire experiment, no adverse reactions such as tingling, numbness or skin damage were reported in the invention group; in the traditional massage group, 3 cases reported mild soreness in the soles of the feet after massage.

[0092] Conclusion: The method of the present invention is significantly effective in relieving plantar fasciitis pain and has extremely high safety and tolerability.

[0093] In summary, this invention innovatively utilizes controllable pulsed ultrasound to achieve a dual-effect synergy of deep cleaning and sterilization with biomimetic acupoint therapy in a single device. Its core technology lies in precisely controlling the ultrasound parameters to physically simulate the mechanical techniques of traditional Chinese acupuncture—"lifting, inserting, twisting, and rotating"—in a liquid medium, achieving non-invasive and precise acupoint stimulation. This not only solves the problems of traditional mechanical massage easily damaging the skin and the safety hazards of electro-pulse water acupuncture, but also verifies through experiments its significant and superior efficacy in promoting blood circulation and relieving pain. Therefore, this invention provides a safe, efficient, and comfortable comprehensive physiotherapy solution.
