Description

Technical Field

[0001] This invention relates to the field of medical device therapy, specifically to an ultrasonic headgear device and treatment method based on acupoint calibration. Background Technology

[0002] Stroke, vascular dementia, carotid artery plaques, and other cardiovascular and cerebrovascular diseases are prevalent chronic diseases worldwide, and their treatment and rehabilitation have always been a key research focus in the medical field. Throughout the long history of medical development, both traditional Chinese and Western medicine have developed unique treatment systems for brain lesions. With the advancement of technology, the integration of traditional treatment methods with modern equipment has become a new trend.

[0003] Traditional Chinese medicine (TCM) associates brain lesions with symptoms such as stroke, dizziness, and dementia, proposing core theories such as "all dizziness and vertigo belong to the liver" and "the brain is the residence of the primordial spirit," laying the foundation for the understanding that the brain is closely related to the internal organs and meridians. Regarding the pathogenesis of diseases, TCM believes that the core of brain lesions in cardiovascular and cerebrovascular diseases lies in "disordered qi and blood, and obstructed meridians," emphasizing the pathological mechanism that "if the meridians are blocked, the brain will not be nourished." Acupuncture, moxibustion, and massage are the core methods, stimulating relevant acupoints on the head and throughout the body to regulate qi and blood. For example, Baihui (GV20) can treat headaches, dizziness, and aphasia caused by stroke; and the fontanelle (BL62) can unblock brain meridians and awaken the mind. However, the location of acupoints depends on the practitioner's experience, and the operation is entirely manual, with accuracy greatly affected by individual skill. With the popularization of physiotherapy equipment, traditional Chinese medicine has begun to try to combine techniques such as electrical stimulation and magnetic therapy with acupoints, resulting in simple acupoint electrical stimulation devices, magnetic therapy head patches, and other equipment. However, these devices can only achieve single physical stimulation, do not combine with the theory of syndrome differentiation in traditional Chinese medicine, and the location of acupoints still relies on manual pressing to find the soreness and distension sensation. They lack objective quantitative standards and are difficult to adapt to the individual differences of different patients.

[0004] With the development of technology, ultrasound technology has been gradually applied in the medical field. By converting electrical energy into mechanical vibration, it utilizes the mechanical and thermal effects of sound waves to improve tissue blood circulation and promote cell metabolism, becoming an auxiliary means of rehabilitation for cardiovascular and cerebrovascular diseases. Early ultrasound therapy equipment mainly consisted of large desktop ultrasound machines with a single rigid probe that needed to be manually held and aimed at a general area of ​​the head. There was no concept of acupoint targeting, and parameters such as frequency and intensity were fixed, allowing only wide-area coverage. Energy transfer efficiency was low, accuracy was low, and treatment effects were poor. To improve accuracy, devices with simple positioning functions emerged, such as the ultrasound therapy device for brain rehabilitation disclosed in application publication number CN108014430A. This device includes a head-mounted treatment end and a main unit connected to the head-mounted treatment end. The head-mounted treatment end includes a skeleton structure for wearing on the human head and an ultrasound therapy head for performing ultrasound therapy. The ultrasound therapy head is installed on the inner wall of the skeleton structure close to the human head. This ultrasound therapy device uses the skeleton structure to fix the treatment head, but the skeleton structure is relatively rigid and cannot adapt to the curvature of different patients' heads, resulting in poor patient comfort.

[0005] Although both traditional Chinese medicine theory and ultrasound technology have been used in the treatment of cardiovascular and cerebrovascular diseases for a long time, both have their own shortcomings. Therefore, how to effectively combine the two and achieve better treatment results by accurately locating the acupoints to be treated through ultrasound therapy has become a technical problem that needs to be solved. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide an ultrasound headgear device based on acupoint calibration, so as to solve the technical problem that existing technologies cannot simultaneously and accurately combine traditional Chinese medicine acupoint therapy and ultrasound therapy to improve the treatment effect; the purpose of this invention is also to provide a treatment method based on acupoint calibration, which can integrate traditional Chinese medicine meridian positioning, ultrasound energy regulation and artificial intelligence to achieve auxiliary treatment and rehabilitation management of cardiovascular and cerebrovascular diseases.

[0007] To solve the above problems, the ultrasonic headgear device based on acupoint calibration provided by the present invention adopts the following technical solution: An ultrasonic headgear device based on acupoint calibration includes an elastic headgear, multiple ultrasonic treatment heads, and multiple impedance electrodes. The elastic headgear has a heat-sensitive layer and a heat-sensitive marking layer. The heat-sensitive layer uses a thermochromic material that changes color at the corresponding acupoints on the head when it comes into contact with the skin of the human head. Multiple ultrasonic treatment heads are detachably connected to the elastic head cover and are used to be attached to the target acupoints on the human head. Multiple impedance electrodes are integrated into the thermal marker layer, each corresponding to a thermal marker in the layer. When powered on, the impedance electrodes scan within a set radius centered on the corresponding thermal marker. The scanning range of the multiple impedance electrodes covers the entire head area. The beneficial effects of the acupoint-based ultrasonic headgear device of the present invention are as follows: The elastic headgear of the present invention can conform to different head shapes and curvatures, has good versatility, and can avoid the pressure of rigid structures, thus improving the comfort of patients. In addition, the thermosensitive layer in the elastic headgear uses a thermochromic material, which can initially change color at the acupoints when in contact with the scalp, realizing the initial positioning of the acupoints. The impedance electrodes connected in the elastic headgear can scan with the thermosensitive markers as the center during operation. Since the scanning range covers the entire head area, a full-head impedance distribution map can be formed to determine which areas are acupoints and which are not. By comparing with the target acupoints in the given prescription, the precise positioning of the target acupoints can be achieved, that is, the precise installation of the ultrasonic treatment head can be realized, avoiding the deviation caused by the traditional method of finding acupoints based on experience, thus achieving precise treatment of the target acupoints and ensuring the treatment effect. The present invention effectively combines acupoint stimulation in traditional Chinese medicine with deep brain targeting in ultrasound technology, and can accurately and effectively treat target acupoints in different locations according to different prescriptions, achieving better treatment results.

[0008] Furthermore, the ultrasonic treatment head is detachably connected to the elastic head cover via magnetic adsorption.

[0009] Beneficial effects: The magnetic adsorption method enables the rapid disassembly and precise fitting of the ultrasonic treatment head, ensuring close contact between the treatment head and acupoints; compared with the adhesive attenuation or displacement problems of traditional patches, the magnetic connection can dynamically adapt to head movements, maintain stable contact pressure, and significantly improve the efficiency of ultrasonic energy transmission.

[0010] Furthermore, the elastic headgear also includes a magnetic fiber layer and an elastic fabric layer disposed between the thermally sensitive layer and the thermally sensitive marking layer, and the ultrasonic treatment head is provided with a strong magnetic part that is attracted to the magnetic fiber layer.

[0011] Beneficial effects: The magnetic fiber layer, in conjunction with the strong magnetic part of the treatment head, enhances the stability of magnetic adsorption and prevents the treatment head from falling off or shifting during use; the elastic fabric layer provides elastic recovery force for the elastic headgear, making it more suitable for the curved contours of different head shapes and further improving wearing comfort; at the same time, the layered design of the magnetic fiber layer, the thermal layer, and the thermal marker layer can avoid interference from magnetism on temperature sensing or impedance detection, ensuring the independence and reliability of positioning and treatment functions.

[0012] Furthermore, the ultrasonic treatment head includes a front cover, a head, an ultrasonic pad, a silicone pad, a rear cover, and wires. The front cover is snapped onto the head and sealed with adhesive. The rear cover is threaded onto the head. The rear cover presses and seals the silicone pad containing coupling agent onto the end face of the head. The ultrasonic pad is fixed inside the head and contacts the silicone pad. The head is provided with the strong magnetic part. The wires are electrically connected to the ultrasonic pad.

[0013] Beneficial effects: The silicone pad with built-in coupling agent reduces ultrasound reflection loss between the skin and the treatment head, improving energy penetration efficiency; the sealed silicone pad design of the rear cover prevents coupling agent loss and ensures the stability of energy transfer during treatment; the gel seal between the front cover and the head, and the threaded connection between the rear cover and the head ensure the waterproof and dustproof performance of core components such as the ultrasound plate inside the treatment head, extending the service life of the equipment and avoiding treatment interruptions due to component damage.

[0014] Furthermore, the elastic headgear has a facial opening for exposing facial organs, a first brain opening and a second brain opening for exposing a portion of the top of the head, and a back brain opening for exposing the back of the head. The elastic headgear also has two neck wraps for wrapping the neck, and the two neck wraps can be detachably glued together.

[0015] Beneficial effects: The facial opening avoids pressure on organs such as the eyes, nose, and mouth, while the openings at the head and back of the head reduce coverage of non-treatment areas, improving breathability and comfort. The neck wrap is detachable and adhesive to adapt to different neck sizes, enhancing the overall stability of the headgear and preventing device displacement due to head movements during treatment. This ensures that the treatment head is always aligned with the target acupoints, further guaranteeing treatment accuracy.

[0016] Furthermore, the ultrasonic treatment head is provided with five parts, which are respectively located at the corresponding fontanelle, internal carotid artery, basilar artery, Baihui acupoint, and the reflex zone on the side of the lesion.

[0017] Beneficial effects: These five acupoints are key targets for TCM treatment of cardiovascular and cerebrovascular diseases. The differentiated layout of the five ultrasound treatment heads can precisely treat the lesion areas of different diseases such as stroke and vascular dementia, improving the targeting and effectiveness of treatment.

[0018] The technical solution of the acupoint-based treatment method provided by this invention is as follows: The treatment method based on acupoint calibration, using any of the above-mentioned technical solutions, employs an ultrasonic headgear device based on acupoint calibration, and includes the following steps: Obtain images of the patient's tongue and pulse; The tongue image and pulse information are processed to generate a prescription; According to the prescription, the ultrasonic treatment head is connected to the elastic head cover in sequence and attached to the target acupoint. The corresponding ultrasonic treatment head is controlled to treat the target acupoints according to the set parameters.

[0019] Furthermore, the processing of the tongue image includes processing four elements: tongue color, tongue coating thickness, crack distribution, and ecchymosis detection. Tongue color is processed using histogram clustering in the HSV color space; in Traditional Chinese Medicine (TCM), tongue color reflects the state of Qi and blood, with red pigment value as the quantitative indicator. Tongue coating thickness is processed using the GLCM texture analysis algorithm; in TCM, tongue coating thickness reflects the degree of internal dampness and turbidity, with coating thickness index as the quantitative indicator. Crack distribution is processed using a combination of Canny edge detection and morphological operations; crack distribution reflects Yin deficiency in TCM, with crack density as the quantitative indicator. Ecchymosis detection is processed using YOLOv5 object detection; in TCM, it reflects blood stasis syndrome, with the number / area ratio of ecchymosis as the quantitative indicator.

[0020] Furthermore, the processing of pulse information includes processing the four elements of pulse location, pulse rate, pulse strength, and pulse shape separately. The pulse location is processed using a pressure amplitude analysis algorithm, which in Traditional Chinese Medicine (TCM) reflects the severity of the disease (exterior or interior), with the pressure ratio at the superficial level as a quantitative indicator. The pulse rate is processed using an FFT spectrum analysis algorithm, which in TCM reflects the slow / slow / rapid nature of the disease, with the dominant frequency as a quantitative indicator. The pulse strength is processed using a signal envelope integral algorithm, which in TCM reflects the differentiation of deficiency and excess, with the pulse strength integral as a quantitative indicator. The pulse shape is processed using a first-order derivative peak detection algorithm, which in TCM reflects the wiry / slippery / hesitant pulse, with the tidal wave height ratio as a quantitative indicator.

[0021] Furthermore, the method for determining the installation position of the ultrasonic treatment head is as follows: First, locate the target acupoints for treatment based on the generated prescription; Then the patient puts the elastic headgear on their head. The heat-sensitive layer on the elastic headgear is activated and initially changes color at the corresponding acupoints on the head, forming a preliminary distribution map of acupoints on the whole head. Each impedance electrode scans to form a full head impedance distribution map. The control system compares the impedance distribution map of the whole head with the characteristics of the target acupoints in the prescription, selects the acupoints that meet the conditions on the head, and activates the thermal markers corresponding to the acupoints. This causes the elastic head cover to display a color marker at the acupoint, which is different from the initial color change of the thermal layer. The ultrasonic treatment head is installed at the aforementioned color marker.

[0022] The beneficial effects of the treatment method of the present invention: 1. The treatment method of this invention involves the acquisition and processing of multimodal data on tongue and pulse patterns, automatically generating a treatment prescription based on quantitative indicators, and utilizing a uniquely designed ultrasound headgear device based on acupoint calibration for treatment. This deeply integrates the dialectical treatment theory of traditional Chinese medicine with ultrasound therapy technology. It retains the core pathogenesis of cardiovascular and cerebrovascular diseases—"disordered qi and blood, and obstructed meridians"—while leveraging the precision of the ultrasound treatment head as a modern device, thus overcoming the shortcomings of traditional ultrasound equipment that can only cover a wide area and lack acupoint targeting. The treatment method of this invention reduces manual intervention through streamlined operation; from diagnosis to the execution of the treatment prescription, it can be automated, solving the problems of high operational thresholds and reliance on human experience in traditional physiotherapy.

[0023] 2. The treatment method of this invention addresses the problem of strong subjectivity and difficulty in quantification in the process of TCM diagnosis. By using an algorithm, the TCM characteristics of tongue and pulse are transformed into objective quantitative indicators. This quantitative processing eliminates the diagnostic bias caused by differences in physician experience, making the generated prescription more accurate, achieving the goal of precise treatment, and thus ensuring the treatment effect.

[0024] 3. The treatment method of the present invention achieves the goal of accurately locating the target acupoints through the initial positioning of the thermosensitive layer on the elastic headgear and the precise verification of the impedance electrode. This solves the problem of low accuracy in acupoint positioning caused by differences in head shape among different patients, thereby enabling precise treatment and ensuring the targeting and effectiveness of ultrasound therapy.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] An embodiment of the ultrasonic headgear device based on acupoint calibration provided by the present invention: like Figure 1 and Figure 2 As shown, the acupoint-based ultrasonic headgear device includes an elastic headgear 1, multiple ultrasonic treatment heads 2, and multiple impedance electrodes.

[0029] Specifically, in terms of appearance, the elastic headgear 1 has a facial opening 18 for exposing facial organs, a first brain opening 15 and a second brain opening 16 for exposing the top of the head, and a back brain opening 17 for exposing the back of the head. The elastic headgear 1 also has two neck wraps 19 for covering the neck, with Velcro fasteners at the two neck wraps 19. These fasteners can be attached together during use and can be removed when not in use. Structurally, as... Figure 5 As shown, the elastic headgear 1 includes a thermosensitive layer 11, a magnetic fiber layer 12, an elastic fabric layer 13, and a thermosensitive marking point layer 14, arranged sequentially from the outside in and bonded together. The thermosensitive layer 11 uses a thermochromic material, which develops color at a critical point of 38°C. Since the temperature of acupoints on the human body is 0.3°C to 0.8°C higher than the surrounding area, when the elastic headgear 1 is worn on the patient's head and comes into contact with the scalp, the thermosensitive layers 11 at the positions corresponding to various acupoints on the head are activated, initially developing color and forming a preliminary distribution map of acupoints across the entire head. In practical applications, the thermochromic material can be an organic fluorane dye or a cholesteric liquid crystal material. Both of these materials meet the requirement of a color-changing temperature close to 38°C, exhibiting obvious color changes and sensitive response, and are compatible with the substrate of the elastic headgear 1.

[0030] like Figure 3 and Figure 4As shown, each ultrasonic treatment head 2 includes a front cover 21, a head 22, an ultrasonic plate 23, a silicone pad 24, a rear cover 25, and a wire 26. The front cover 21 is fastened to the head 22 via a pin and a socket, and the seam around the fastening point is sealed with adhesive. The rear cover 25 is threaded onto the side of the head 22 opposite to the front cover 21, and the rear cover 25 presses the silicone pad 24, which contains coupling agent, onto the rear end face of the head 22. The ultrasonic plate 23 is a ceramic plate, fixed inside the head 22 and in contact with the silicone pad 24. The wire 26 is electrically connected to the ultrasonic plate 23 and is used to connect to control equipment. A strong magnetic section is provided in the head 22, using neodymium iron boron permanent magnets, which have high magnetic strength, small size, and high stability. The strong magnetic section is magnetically attracted to the magnetic fiber layer 12 in the elastic head cover 1, achieving reliable fixation of the ultrasonic treatment head 2 on the elastic head cover 1. In use, the silicone pad 24 is placed against the acupoints on the head that require treatment. Since the ultrasonic treatment head 2 is fixed by magnetic force, after treatment, it can be pulled out of the elastic head cover 1 by using a force greater than the suction force, thus disassembling the ultrasonic treatment head 2. The working principle of the ultrasonic treatment head 2 is to convert electrical energy into mechanical energy to achieve directional energy transfer. This technology is existing and will not be described in detail here.

[0031] Sixty-four impedance electrodes are evenly distributed on the elastic headgear 1. Multiple impedance electrodes are integrated and adhered to the thermal marker layer 14, each individually connected to a cable, corresponding one-to-one with a thermal marker on the layer 14. When powered on, the impedance electrodes scan within a 10mm radius of their corresponding thermal marker. The scanning range of multiple impedance electrodes covers the entire head area, forming a full-head impedance distribution map. The working principle of the impedance electrodes is based on the different impedance values ​​of acupoint and non-acupoint areas on the head. The impedance of acupoint areas is 50-100kΩ, while the impedance of non-acupoint areas is 200-500kΩ, showing a significant difference.

[0032] It should be noted that the acupoint-based ultrasonic headgear device of the present invention needs to be connected to a control system during use. This control system generates a corresponding prescription for each patient, determines the acupoints to be treated based on the symptoms in the prescription, and, based on the initial color change of the thermosensitive layer 11 and further comparison and screening by the impedance electrodes, finally activates the thermosensitive marker point of the target treatment acupoint on the elastic headgear 1, making its color distinct from that of other acupoints. After the user installs the ultrasonic treatment head in the above position, the control system can control the corresponding ultrasonic treatment head to work and treat according to the set parameters according to the prescription.

[0033] Taking the patient's syndrome of liver yang hyperactivity with phlegm as an example, its specific manifestations are red tongue with yellow and greasy coating and slippery and rapid pulse, which corresponds to dizziness and high blood pressure during the recovery period of stroke. The target acupoints are the fontanelle, internal carotid artery, basilar artery, Baihui acupoint, and the lesion side head reflex zone. That is, the five ultrasonic treatment heads are respectively attached to the positions of the elastic head cover corresponding to the above five acupoints.

[0034] It should be noted that the number of ultrasonic treatment heads is not limited to the five mentioned above. During treatment, the number of heads used should correspond to the number of acupoints targeted according to the given prescription. Similarly, the number of impedance electrodes is not limited to the 64 mentioned above and can be used according to actual needs.

[0035] The acupoint-based ultrasound headgear of this invention can fit patients with different head shapes and curvatures, offering good versatility. During use, it can accurately locate the target acupoints according to the prescription, avoiding the errors caused by traditional methods that rely on experience to find acupoints. This invention creatively and effectively combines acupoint stimulation from Traditional Chinese Medicine with deep brain targeting in ultrasound technology, thus improving treatment efficacy.

[0036] An embodiment of the acupoint-based treatment method provided by this invention: Treatment is performed using an ultrasonic headgear device based on acupoint calibration, employing the ultrasonic headgear device based on acupoint calibration described in the above embodiments, such as... Figure 6 As shown, it includes the following steps: Step 1: Obtain the patient's tongue image and pulse information; Step 2: Process the tongue image and pulse information to generate a prescription; Step 3: According to the prescription, connect the ultrasonic treatment head to the elastic head cover in sequence and attach it to the target acupoints. Step 4: Control the corresponding ultrasonic treatment head to treat the target acupoints according to the set parameters.

[0037] In step one, the tongue image can be captured using a mobile phone, camera, or other device with a camera function. The tongue image displays four elements: tongue color, tongue coating thickness, distribution of cracks, and ecchymosis. Pulse information is obtained by wearing a wristband pulse monitor, including four elements: pulse location, pulse rate, pulse strength, and pulse shape.

[0038] Step two involves processing four elements of the tongue image: tongue color, tongue coating thickness, crack distribution, and ecchymosis detection. Tongue color is processed using histogram clustering in the HSV color space. In Traditional Chinese Medicine (TCM), tongue color reflects the state of Qi and blood, quantified by hemoglobin values ​​ranging from 0 to 100. Tongue coating thickness is processed using the GLCM texture analysis algorithm. In TCM, tongue coating thickness reflects the degree of internal dampness and turbidity, quantified by a coating thickness index, graded from 1 to 5. Crack distribution is processed using a combination of Canny edge detection and morphological operations. In TCM, crack distribution reflects Yin deficiency, quantified by crack density (pixels / square centimeter). Ecchymosis detection uses YOLOv5 object detection. In TCM, ecchymosis reflects blood stasis, quantified by the number / area ratio of ecchymosis.

[0039] Step two involves processing pulse information, specifically the four elements of pulse location, pulse rate, pulse strength, and pulse shape. Pulse location is processed using a pressure amplitude analysis algorithm, reflecting the severity of the condition in Traditional Chinese Medicine (TCM), with the superficial pressure ratio as the quantification indicator. Pulse rate is processed using an FFT spectral analysis algorithm, reflecting the slow / slow / rapid nature of the pulse in TCM, with the dominant frequency as the quantification indicator. Pulse strength is processed using a signal envelope integral algorithm, reflecting the differentiation of deficiency and excess in TCM, with the pulse strength integral as the quantification indicator. Pulse shape is processed using a first-order derivative peak detection algorithm, reflecting the wiry / slippery / hesitant pulse in TCM, with the tidal wave height ratio as the quantification indicator.

[0040] It should be noted that HSV color space histogram clustering, GLCM texture analysis, Canny edge detection and morphological operation, YOLOv5 target detection, pressure amplitude analysis, FFT spectrum analysis, signal envelope integration, and first derivative peak detection are all algorithms in existing technologies, and the specific processes will not be described in detail.

[0041] In step three, the method for determining the installation position of the ultrasonic treatment head is as follows: First, locate the target acupoints for treatment based on the generated prescription; The patient wears the elastic headgear, and the thermal layer on the headgear is activated. Due to temperature differences, the thermal material in the corresponding areas of all acupoints on the head initially shows color, forming a preliminary distribution map of acupoints on the whole head. After each impedance electrode is energized, it is scanned, and the scanning area covers the entire head. The skin impedance value of each area is collected to form a full head impedance distribution map. The control system compares the whole-head impedance distribution map with the characteristics of the target acupoints in the generated prescription, and filters out acupoints that meet the conditions on the head. For example, if the target acupoint in the prescription is Baihui, the system will look for a location with an impedance of 50~100kΩ in the whole-head impedance data, located in the midline area of ​​the top of the head, and where the thermal layer has initially shown color, excluding non-acupoint areas and non-target acupoints. After locking the location of the target acupoint, the system will activate the thermal marker corresponding to the target acupoint location, so that it displays a color different from the initial color of the thermal layer under the dual action of temperature and system commands. At this time, the therapist can clearly observe the location of the target acupoint on the elastic head cover and then install the ultrasonic treatment head at that location.

[0042] This invention's treatment method utilizes multimodal data acquisition. The patient photographs their tongue using their mobile phone, and a wristband-type pulse diagnostic device collects the pulse, transforming the diagnostic information from traditional Chinese medicine's "tongue observation and pulse diagnosis" into quantitative indicators. The control system uses a multimodal fusion algorithm to determine the symptom type and automatically generate a prescription, identifying the target acupoints and their corresponding physiological functions. Then, the elastic headgear's material and impedance electrodes precisely locate the target acupoints, ultimately using an ultrasonic treatment head for precise treatment. Compared to traditional treatment methods, this invention deeply integrates traditional Chinese medicine's diagnostic and treatment theories with ultrasonic therapy technology, overcoming the limitation of traditional ultrasound equipment lacking acupoint targeting. It also eliminates diagnostic biases caused by differences in physician experience, resulting in more accurate prescriptions and achieving precise and efficient treatment.

[0043] Here are some application scenario examples: The patient's tongue was red with a yellow, greasy coating. Algorithm calculations showed a hemoglobin value of 78, a coating thickness index of 4, a crack density of 0.2, and a ecchymosis number / area ratio of 0.25. The pulse analysis showed a superficial pressure ratio of 0.54, a dominant frequency of 2.2 Hz, a pulse force integral of 0.26, and a tidal wave height ratio of 0.28. Based on this data, the system determined the syndrome to be liver yang hyperactivity with phlegm (manifested as a red tongue with a yellow, greasy coating and a slippery, rapid pulse, corresponding to dizziness and high blood pressure during the recovery period after stroke). The target acupoints were identified as the fontanelle, internal carotid artery, basilar artery, Baihui (GV20), and the lesion-side head reflex zone. Five ultrasonic treatment heads were attached to the corresponding acupoints on the elastic headgear. The settings for the five treatment heads are shown below: The No. 1 ultrasonic therapy head is attached to the fontanelle, with a set frequency of 0.8MHz, a continuous waveform, an intensity of 800, a continuous timing mode, and a mechanism of action of gentle stimulation to refresh the mind and relieve dizziness.

[0044] The second ultrasonic treatment head is attached to the artery within the well, with the frequency set to 1.0MHz, the waveform to be a pulse wave, and the intensity to be... The timing mode is intermittent, with a 5-second on-time followed by a 3-second interruption. Its mechanism of action is to enhance blood flow and dissolve micro-plaques.

[0045] The No. 3 ultrasonic treatment head is attached to the basilar artery, the frequency is set to 1.0MHz, the waveform is a pulse wave, and the intensity is... The timing mode is intermittent, with a 4-second on-time followed by a 2-second interruption. Its mechanism of action is to improve posterior circulation and reduce dizziness.

[0046] The No. 4 ultrasonic therapy head is attached to the Baihui acupoint, the frequency is set to 1.2MHz, the waveform is a pulse wave, and the intensity is... The time sequence is continuous, and the mechanism of action is to calm the liver and subdue yang, and regulate blood pressure.

[0047] The No. 5 ultrasonic treatment head is attached to the reflex area on the side of the lesion, with the frequency set to 0.6MHz, the waveform to be a continuous wave, and the intensity to be... The timing pattern is continuous, and the mechanism of action is to promote the recovery of limb function on the lesion side.

[0048] Of course, the above is just one example. In actual application, the system will generate prescriptions corresponding to individuals based on individual differences, and then carry out targeted treatment for different individuals' symptoms.

[0049] In the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

8. The treatment method based on acupoint calibration according to claim 7, characterized in that, The processing of tongue images includes processing four elements: tongue color, tongue coating thickness, crack distribution, and ecchymosis detection. Tongue color is processed using histogram clustering in the HSV color space; in Traditional Chinese Medicine (TCM), tongue color reflects the state of Qi and blood, with red pigment value as the quantitative indicator. Tongue coating thickness is processed using the GLCM texture analysis algorithm; in TCM, tongue coating thickness reflects the degree of internal dampness and turbidity, with coating thickness index as the quantitative indicator. Crack distribution is processed using a combination of Canny edge detection and morphological operations; crack distribution reflects Yin deficiency in TCM, with crack density as the quantitative indicator. Ecchymosis detection is processed using YOLOv5 object detection; in TCM, it reflects blood stasis syndrome, with the number / area ratio of ecchymosis as the quantitative indicator.

9. The treatment method based on acupoint calibration according to claim 7, characterized in that, The processing of pulse information includes processing four elements: pulse location, pulse rate, pulse strength, and pulse shape. The pulse location is processed using a pressure amplitude analysis algorithm, which in Traditional Chinese Medicine (TCM) reflects the severity of the disease (exterior or interior), with the superficial pressure ratio as a quantitative indicator. The pulse rate is processed using an FFT spectrum analysis algorithm, which in TCM reflects the slow / slow / rapid nature, with the dominant frequency as a quantitative indicator. The pulse strength is processed using a signal envelope integral algorithm, which in TCM reflects the differentiation of deficiency and excess, with the pulse strength integral as a quantitative indicator. The pulse shape is processed using a first-order derivative peak detection algorithm, which in TCM reflects the wiry / slippery / hesitant pulse, with the tidal wave height ratio as a quantitative indicator.

10. The treatment method based on acupoint calibration according to claim 7, characterized in that, The method for determining the installation position of the ultrasonic treatment head is as follows: First, locate the target acupoints for treatment based on the generated prescription; Then the patient puts the elastic headgear on their head. The heat-sensitive layer on the elastic headgear is activated and initially changes color at the corresponding acupoints on the head, forming a preliminary distribution map of acupoints on the whole head. Each impedance electrode scans to form a full head impedance distribution map. The control system compares the impedance distribution map of the whole head with the characteristics of the target acupoints in the prescription, selects the acupoints that meet the conditions on the head, and activates the thermal markers corresponding to the acupoints. This causes the elastic head cover to display a color marker at the acupoint, which is different from the initial color change of the thermal layer. The ultrasonic treatment head is installed at the aforementioned color marker.
