Description

Technical Field

[0001] This invention relates to the field of acupuncture treatment technology, specifically to an electric acupuncture rehabilitation device for stroke patients. Background Technology

[0002] Stroke patients often experience limb dysfunction and diminished acupoint perception after the onset of the disease. Acupuncture rehabilitation therapy is an important means to improve their limb function. Electric acupuncture devices, due to their ability to reduce manual operation, have been gradually applied in the clinical rehabilitation treatment of stroke patients. However, existing electric acupuncture rehabilitation devices on the market have significant deficiencies in terms of suitability and safety for stroke patients, making it difficult to meet the actual needs of clinical treatment. The most critical problem is the inability to simultaneously achieve precise control of acupuncture parameters, adaptive adjustment of patient limb posture, and safety protection during the treatment process, resulting in poor treatment effects and potential safety hazards.

[0003] Traditional electric acupuncture devices rely heavily on the manual experience of medical personnel to adjust the puncture depth and contact force of the acupuncture needles. Lacking precise control mechanisms, they struggle to flexibly adjust parameters according to the needs of stroke patients at different stages of rehabilitation. Excessive force can damage acupoints, while insufficient force may fail to achieve the desired therapeutic effect. Stroke patients, with their fragile limbs and diminished senses, are highly susceptible to secondary injuries due to these abnormalities, severely compromising the safety of treatment.

[0004] In summary, traditional electric acupuncture devices suffer from insufficient adaptability and safety due to their inability to simultaneously address the core issue of precise control of acupuncture parameters, making it difficult to meet the rehabilitation needs of stroke patients. There is an urgent need for an electric acupuncture rehabilitation device that can solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an electric acupuncture rehabilitation treatment device for stroke patients. This device solves the issues of traditional electric acupuncture devices' inability to simultaneously achieve precise control of acupuncture needle puncture depth and contact force, adaptive adjustment of patient limb posture, and safety protection during the treatment process. These limitations result in poor adaptability and insufficient safety, making it difficult to meet the rehabilitation needs of stroke patients. The invention improves the accuracy, safety, and adaptability of acupuncture treatment, reduces the operational burden on medical staff, and ensures the smooth progress of stroke patient rehabilitation.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An electric acupuncture rehabilitation treatment device for stroke patients, comprising a device base, an acupuncture execution module, and a control unit. The control unit is used to receive and process signals collected during the operation of the acupuncture execution module and control the operation of the acupuncture execution module. It also includes an adjustment structure, an adaptive structure, and a protective structure. The adjustment structure is used to regulate the puncture depth and contact force of the acupuncture needle. The adaptive structure is used to automatically adjust the position and angle of the acupuncture execution module according to changes in the patient's limb posture. The protective structure is used to monitor abnormal pressure and acupuncture needle deviation during treatment in real time and trigger protective actions. The adjustment structure is embedded inside the acupuncture execution module, the adaptive structure is hinged between the top of the device base and the bottom of the acupuncture execution module, and the protective structure is partially embedded in the front end of the acupuncture execution module.

[0007] The acupuncture execution module, adjustment structure, adaptive structure, and protective structure are all connected to the control unit. The control unit receives pressure and acupuncture needle deviation detection signals from the protective structure, analyzes and processes the pressure and acupuncture needle deviation detection signals, and then synchronously outputs control commands to the acupuncture execution module, adjustment structure, and adaptive structure.

[0008] Furthermore, the adjustment structure includes a drive unit and a pressure sensor. The output shaft of the drive unit is coaxially fixedly connected to a lead screw, and a nut seat is threaded onto the lead screw. The acupuncture execution module is fixedly connected to the nut seat. The pressure sensor is installed on the acupuncture execution module and is used to collect real-time contact pressure data between the acupuncture needle and the patient's acupoint. Both the drive unit and the pressure sensor are signal-connected to the control unit. The control unit is used to adjust the speed and direction of the drive unit according to the pressure data fed back by the pressure sensor, thereby driving the acupuncture execution module to move up and down through the threaded engagement of the lead screw and the nut seat.

[0009] Furthermore, the acupuncture execution module includes a housing, an acupuncture needle holder, a guide assembly, and a mounting bracket. The housing is fixedly connected to the device base and has a hollow structure. The mounting bracket is fixedly connected inside the housing, and the drive component is fixedly mounted on the mounting bracket. The acupuncture needle holder is fixedly connected to a nut seat and has needle holes for fixing acupuncture needles. The guide assembly includes a guide plate and a guide protrusion. The guide plate is fixedly connected to the inner wall of the housing, and the inner wall of the guide plate has several symmetrical guide grooves along the axial direction. The guide protrusion is fixedly connected to the outer side of the acupuncture needle holder and is embedded in the guide groove and slides with the guide groove.

[0010] Furthermore, the adaptive structure includes several articulated links, articulated seats, several drive servos, and angle sensors. The articulated seats are fixedly connected to the top of the device base. One end of each articulated link is hinged to the articulated seat, and the other end of each articulated link is hinged to the mounting bracket. Each articulated link has a hinge shaft installed at its hinge joint. Drive servos are installed at each hinge joint of the articulated link, and the output shaft of the drive servo is fixedly connected to the hinge shaft. The drive servos are used to drive the link to rotate around the hinge shaft. Angle sensors are embedded at the hinge joints of the articulated links and are signal-connected to the control unit. The angle sensors are used to detect the patient's limb posture deviation angle in real time and feed it back to the control unit. The control unit synchronously drives the drive servos at the corresponding hinge joint according to the deviation angle, and simultaneously adjusts the drive components of the adjustment structure and the pressure sensor to adjust the puncture depth and contact force of the acupuncture needle.

[0011] Furthermore, the protective structure includes a displacement sensor, an emergency braking component, and a flexible protective sleeve. The flexible protective sleeve is fitted onto the end of the acupuncture execution module near the tip of the acupuncture needle. The displacement sensor is embedded in the inner wall of the flexible protective sleeve and is signal-connected to the control unit. The displacement sensor is used to detect the radial offset of the acupuncture needle in real time.

[0012] The emergency braking assembly includes an electromagnetic brake pad and a return spring. The electromagnetic brake pad is mounted on the output shaft of the drive unit. One end of the return spring is fixedly connected to the end of the acupuncture needle fixing seat away from the needle tip, and the other end of the return spring is fixedly connected to the end of the guide plate near the mounting bracket.

[0013] When the acupuncture needle deviates or is subjected to abnormal pressure, the control unit immediately triggers the emergency braking component. The electromagnetic brake pads lock the output shaft of the drive component, stopping the operation of the adjustment structure. At the same time, the reset spring contracts, causing the acupuncture needle holder to move in the opposite direction, allowing the acupuncture needle to quickly detach from the patient's acupoint. Simultaneously, the drive servo motor of the adaptive structure stops its operation.

[0014] Furthermore, it also includes a warning component, which includes a buzzer and an indicator light. Both the buzzer and the indicator light are fixedly installed on the side wall of the device base and are electrically connected to the control unit. When the acupuncture needle deflection exceeds the preset deflection threshold in the control unit, or the pressure exceeds the preset range of the corresponding rehabilitation stage for the stroke patient, the control unit simultaneously triggers the warning component and the emergency braking component. The buzzer sounds a warning and the indicator light illuminates. When the abnormality is eliminated, the warning component stops working.

[0015] Furthermore, the device base is equipped with a limb fixation assembly, which includes an arc-shaped support plate and an electric adjustment rod. The electric adjustment rod is fixedly connected to the device base, and the end of the electric adjustment rod away from the device base is fixedly connected to the arc-shaped support plate. A medical flexible cushioning pad is detachably connected to the inner wall of the arc-shaped support plate. The electric adjustment rod is electrically connected to the control unit. The control unit is used to receive limb posture signals fed back by the adaptive structural angle sensor and synchronously drive the electric adjustment rod to extend and retract, so as to realize the adaptive adjustment of the height of the arc-shaped support plate.

[0016] Furthermore, several ventilation holes are provided on the arc-shaped support plate, and the ventilation holes are evenly distributed on the arc-shaped support plate.

[0017] Furthermore, a binding assembly is also installed on the curved pallet. The binding assembly includes binding straps, Velcro, and adjusting buckles. The Velcro is fixedly connected to the binding straps. One end of the binding strap is fixedly connected to one side of the curved pallet. The adjusting buckle is fixedly installed on the other side of the curved pallet. The end of the binding strap away from the curved pallet passes through the adjusting buckle and is detachably glued to it by the Velcro.

[0018] Furthermore, the control unit is electrically connected to a power module, a wireless communication module, and a display screen. The power module is used to supply power to the various components of the device, and the wireless communication module is used to establish Bluetooth or WiFi communication with external medical terminals and receive control commands sent by external terminals. The display screen is embedded in the side wall of the device base and is used to display various operating parameters and abnormal warning information in real time.

[0019] The above approach has the following beneficial effects:

[0020] 1. This solution achieves precise control of acupuncture needle puncture depth and contact force through the coordinated linkage of the adjustment structure, adaptive structure, and control unit. At the same time, it can automatically adjust the position and angle of the acupuncture execution module according to the changes in the patient's limb posture. Compared with the electric acupuncture devices in traditional technology, it solves the defects of traditional devices that rely on manual experience operation, cannot accurately control acupuncture parameters, and are difficult to adapt to changes in the patient's limb posture. It effectively avoids acupoint damage caused by improper force or acupoint alignment deviation, greatly improves the accuracy of acupuncture rehabilitation treatment, adapts to the treatment needs of stroke patients at different rehabilitation stages, and reduces the operation difficulty for medical staff.

[0021] 2. The protective structure, adjustment structure, and adaptive structure of this solution form a full-process linkage protection system, which can monitor the acupuncture needle deviation and abnormal pressure during the treatment process in real time and quickly trigger emergency braking and reset actions. Compared with the electric acupuncture devices in traditional technology, traditional devices lack effective safety monitoring and protection mechanisms, which can easily cause secondary damage to stroke patients with fragile limbs and dulled senses. This solution significantly improves the treatment safety of the device through multi-structure linkage protection, eliminates adverse consequences caused by abnormal situations, and ensures the personal safety of patients during the treatment process.

[0022] 3. The limb fixation components and adaptive structure of this solution work in conjunction, adaptively adjusting the height based on the patient's limb posture signals. Simultaneously, the binding components ensure stable limb fixation. The ventilation holes in the arc-shaped support plate and the medical-grade flexible cushioning pad work together to enhance patient comfort. Compared to traditional electric acupuncture devices, which often lack a limb fixation structure suitable for stroke patients, or have a rigid and uncomfortable structure that easily leads to limb movement and skin discomfort, this solution's fixation components are designed to better suit the limited limb movement characteristics of stroke patients. This ensures limb fixation stability while improving patient comfort during treatment. Furthermore, it adapts to different limb sizes, expanding the device's applicability.

[0023] 4. The early warning component, wireless communication module, and display screen in this solution enable real-time early warning, remote monitoring, and visual viewing of the treatment process. Compared with traditional electric acupuncture devices, which often require on-site monitoring by medical staff, are cumbersome to operate and make it difficult to detect abnormalities in a timely manner, this solution can promptly remind medical staff to handle abnormalities through the early warning component, achieve remote control and data transmission through the wireless communication module, and display operating parameters in real time through the display screen. This significantly reduces the workload of medical staff, improves the ease of operation and intelligence of the device, and adapts to the needs of stroke rehabilitation treatment in various scenarios.

[0031] The following detailed description illustrates the specific implementation method:

[0032] Example 1:

[0033] As attached Figures 1 to 3 The device, as shown, is an electric acupuncture rehabilitation treatment device for stroke patients. It includes a base 1, an acupuncture execution module, a control unit, and a power supply module. The control unit receives and processes signals collected during the operation of the acupuncture execution module and controls its operation. It includes an adjustment structure, an adaptive structure, and a protective structure. The adjustment structure regulates the puncture depth and contact force of the acupuncture needles. The adaptive structure automatically adjusts the position and angle of the acupuncture execution module based on changes in the patient's limb posture. The protective structure monitors abnormal pressure and acupuncture needle deviation during treatment in real time and triggers protective actions promptly. The adjustment structure is embedded within the acupuncture execution module, the adaptive structure is hinged between the top of the base 1 and the bottom of the acupuncture execution module, and the protective structure is partially embedded at the front end of the acupuncture execution module. The acupuncture execution module, adjustment structure, adaptive structure, and protective structure are all signal-connected to the control unit. The control unit receives pressure and acupuncture needle deviation detection signals from the protective structure, analyzes and processes these signals, and synchronously outputs control commands to the acupuncture execution module, adjustment structure, and adaptive structure. The power supply module provides power to the acupuncture execution module, adjustment structure, adaptive structure, and protective structure.

[0034] The adjustment structure includes a drive unit 2 and a pressure sensor. In this embodiment, the drive unit 2 is a servo motor. The output shaft of the drive unit 2 is coaxially fixedly connected to a lead screw 3. A nut seat 4 is threaded onto the lead screw 3. The acupuncture execution module is fixedly connected to the nut seat 4. The pressure sensor is installed on the acupuncture execution module. The pressure sensor is used to collect the contact pressure data between the acupuncture needle and the patient's acupoint in real time. Both the drive unit 2 and the pressure sensor are signal-connected to the control unit. The control unit is used to adjust the speed and direction of the drive unit 2 according to the pressure data fed back by the pressure sensor. Then, through the threaded engagement of the lead screw 3 and the nut seat 4, the acupuncture execution module is driven to move up and down, and the up and down movement speed of the acupuncture execution module is adjusted (to match the speed).

[0035] The acupuncture execution module includes a housing 5, an acupuncture needle holder 6, a guide assembly, and a mounting bracket 7. The housing 5 is fixedly connected to the device base 1. The housing 5 has a hollow structure. The mounting bracket 7 is fixedly connected inside the housing 5. The drive component 2 is fixedly installed on the mounting bracket 7. The acupuncture needle holder 6 is fixedly connected to the nut seat 4. The acupuncture needle holder 6 has a needle hole 601 for fixing the acupuncture needle. The pressure sensor is installed inside the needle hole 601. The guide assembly includes a guide plate 8 and a guide protrusion 9. The guide plate 8 is fixedly connected to the inner wall of the housing 5. The inner wall of the guide plate 8 has several symmetrical guide grooves 801 along its length. The guide protrusion 9 is fixedly connected to the outer side of the acupuncture needle holder 6. The guide protrusion 9 is embedded in the guide groove 801 and slides with the guide groove 801.

[0036] The adaptive structure includes several articulated links, articulated seats, several drive servos, and angle sensors. The articulated seats are fixedly connected to the top of the device base 1. One end of each articulated link is hinged to the articulated seat, and the other end of each articulated link is hinged to the mounting bracket 7. Each articulated link has an articulated shaft installed at its articulation point. Each drive servo is installed at each articulation point of the articulated link, and the output shaft of the drive servo is fixedly connected to the articulated shaft. The drive servo is used to drive the link to rotate around the articulated shaft. Angle sensors are embedded at the articulation points of the articulated links and are signal-connected to the control unit. The angle sensors are used to detect the angle of the patient's limb posture deviation in real time and feed it back to the control unit. The control unit synchronously drives the drive servos at the corresponding articulation point according to the deviation angle, and simultaneously adjusts the drive component 2 of the adjustment structure and the pressure sensor to adjust the puncture depth and contact force of the acupuncture needle.

[0037] The protective structure includes a displacement sensor, an emergency braking assembly, and a flexible protective sleeve. The flexible protective sleeve is fitted onto the end of the acupuncture execution module near the acupuncture needle tip. The displacement sensor is embedded in the inner wall of the flexible protective sleeve and is signal-connected to the control unit. The displacement sensor is used to detect the radial offset of the acupuncture needle in real time. The emergency braking assembly includes an electromagnetic brake pad and a return spring. The electromagnetic brake pad is mounted on the output shaft of the drive component 2. One end of the return spring is fixedly connected to the end of the acupuncture needle fixing seat 6 away from the needle tip, and the other end of the return spring is fixedly connected to the end of the guide plate 8 near the mounting bracket 7. When the acupuncture needle deviates or experiences abnormal pressure, the control unit immediately triggers the emergency braking assembly. The electromagnetic brake pad locks the output shaft of the drive component 2, stopping the operation of the adjustment structure. At the same time, the return spring contracts, causing the acupuncture needle fixing seat 6 to move in the opposite direction, allowing the acupuncture needle to quickly detach from the patient's acupoint. Simultaneously, the drive servo of the adaptive structure stops its operation.

[0038] The specific implementation process is as follows: First, place the device on a flat treatment table, connect the power module, and ensure that the power module provides stable power to all components, including the device base 1, acupuncture execution module, control unit, adjustment structure, adaptive structure, and protective structure. Considering the characteristics of stroke patient rehabilitation, the control unit presets the acupuncture needle puncture depth range, contact pressure threshold, and acupuncture needle radial offset threshold. After setting, the acupuncture needles suitable for stroke patient treatment are fixed through the needle holes 601 on the acupuncture needle fixing seat 6, ensuring the acupuncture needles are securely installed and preventing them from falling off during treatment.

[0039] During treatment, the stroke patient places the limb to be treated on the device base 1, so that the flexible protective sleeve at the front end of the acupuncture execution module fits into the area where the acupoint is located. The flexible protective sleeve is made of medical silicone material, which can prevent the acupuncture execution module shell 5 from directly contacting the patient's skin and causing friction damage, while not affecting the acupuncture needle puncture operation. After the device is started, the control unit simultaneously activates the adjustment structure, adaptive structure, and protective structure, and each structure begins to operate in coordination: the angle sensor of the adaptive structure detects the patient's limb posture in real time. Because stroke patients have limited limb movement, they are prone to unconscious posture deviations. When the angle sensor detects a limb posture deviation, it immediately feeds back the deviation angle signal to the control unit. After the control unit quickly analyzes and processes the signal, it synchronously drives the drive servo motors at each hinge of the adaptive structure. The drive servo motor output shaft drives the hinge shaft to rotate, which in turn drives the hinge link to rotate around the hinge shaft. Since one end of the hinge link is hinged to the hinge seat of the device base 1, and the other end is hinged to the bottom of the housing 5 of the acupuncture execution module, the rotation of the hinge link can drive the acupuncture execution module to synchronously adjust its position and angle, ensuring that the acupuncture needle is always aligned with the patient's target acupoint without the need for the patient to actively adjust their limb, thus meeting the core needs of stroke patients with limited limb movement.

[0040] While the adaptive structure adjusts the position of the acupuncture execution module, the control unit's linkage adjustment structure begins to operate. The servo motor of the adjustment structure starts, and its output shaft drives the lead screw 3 to rotate synchronously. Since the lead screw 3 is threadedly engaged with the nut seat 4, and the acupuncture needle fixing seat 6 is fixedly connected to the nut seat 4, the rotation of the lead screw 3 causes the nut seat 4 to move up and down along the axis of the lead screw 3, thereby driving the acupuncture needle fixing seat 6 and the acupuncture needle to move synchronously, realizing the puncture action of the acupuncture needle. At this time, the guiding component of the acupuncture execution module plays a linkage role. The guide protrusion 9 on the outer side of the acupuncture needle fixing seat 6 slides along the guide groove 801 on the inner wall of the guide plate 8, effectively limiting the radial sway of the acupuncture needle fixing seat 6, preventing the acupuncture needle from deviating during puncture, ensuring accurate puncture direction, and forming a synergistic linkage with the posture adjustment of the adaptive structure, significantly improving the accuracy of acupuncture.

[0041] After the acupuncture needle contacts the patient's acupoint, the pressure sensor of the adjustment structure collects the contact pressure data between the acupuncture needle and the acupoint in real time and feeds the data back to the control unit. The control unit precisely adjusts the speed and direction of the servo motor according to the preset pressure threshold: when the pressure sensor detects that the contact pressure is less than the preset threshold, the control unit controls the servo motor to accelerate, driving the lead screw 3 to rotate in the forward direction, causing the acupuncture needle fixing seat 6 to move downward, increasing the puncture depth and contact force; when the pressure sensor detects that the contact pressure is greater than the preset threshold, the control unit controls the servo motor to decelerate or rotate in the reverse direction, driving the lead screw 3 to rotate in the reverse direction, causing the acupuncture needle fixing seat 6 to move upward, reducing the puncture depth and contact force, until the contact pressure reaches the preset range. This effectively solves the defects of existing devices that cannot accurately control the acupuncture depth and force and rely on manual experience, avoiding damage to the patient's acupoint due to improper force. It can flexibly adapt to the different rehabilitation needs of stroke patients in the acute, recovery, and sequelae stages, without the need for manual adjustment, reducing the operational difficulty for medical staff and improving the standardization and accuracy of treatment.

[0042] During treatment, the protective structure is constantly under real-time monitoring. A displacement sensor, embedded in the inner wall of the flexible protective sleeve, detects the radial offset of the acupuncture needle in real time, while a pressure sensor continuously monitors the contact pressure. Both data are synchronously fed back to the control unit. If the patient's limb suddenly moves, causing the radial offset of the acupuncture needle to exceed the preset offset threshold, or if a servo motor malfunctions or the adaptive structure fails to adjust in time, causing the contact pressure to exceed the preset range, the control unit immediately triggers the emergency braking component of the protective structure: the electromagnetic brake quickly locks the output shaft of the servo motor, stopping the lead screw 3 from rotating, thus stopping the operation of the adjustment structure and preventing further offset of the acupuncture needle or continued abnormal pressure. Simultaneously, the return spring rapidly contracts, causing the acupuncture needle fixing seat 6 to move in the opposite direction, allowing the acupuncture needle to quickly detach from the patient's acupoint. This synchronously controls the drive servo motor of the adaptive structure to stop, preventing the hinged linkage from continuing to rotate and causing further offset of the acupuncture needle. This effectively solves the shortcomings of existing devices, such as lack of safety protection and real-time monitoring functions, and the potential for secondary injury to the patient. It is tailored to the characteristics of stroke patients, whose limbs are fragile and whose senses are impaired, significantly improving the safety of the device.

[0043] After treatment, the control unit controls the servo motor to rotate in the opposite direction, causing the acupuncture needle holder 6 to move upward, so that the acupuncture needle is removed from the patient's acupoint. At the same time, it controls the drive servo motor of the adaptive structure to move the hinge link to reset, so that the acupuncture execution module returns to its initial position. Then, the power of the device is turned off, the acupuncture needle is removed and disinfected, and the flexible protective cover can be directly removed for cleaning and disinfection, which is convenient for subsequent reuse.

[0044] Example 2:

[0045] The difference from Embodiment 1 is that it also includes a warning component, which includes a buzzer and an indicator light. Both the buzzer and the indicator light are fixedly installed on the side wall of the device base 1 and are electrically connected to the control unit. When the acupuncture needle deflection exceeds the preset deflection threshold in the control unit, or the pressure exceeds the preset range of the corresponding rehabilitation stage of the stroke patient, the control unit simultaneously triggers the warning component and the emergency braking component, the buzzer sounds a warning, and the indicator light lights up; when the abnormality is eliminated, the warning component stops working.

[0046] The control unit is electrically connected to a wireless communication module and a display screen 13. The wireless communication module is used to establish Bluetooth or WiFi communication with an external medical terminal and receive control commands sent by the external terminal. The display screen 13 is embedded in the side wall of the device base 1 and is used to display various operating parameters and abnormal warning information in real time.

[0047] The specific implementation process is as follows: After the device is started, the early warning component, wireless communication module, and display screen 13 are activated synchronously with the control unit. The display screen 13 displays operating parameters such as acupuncture needle puncture depth, contact pressure, and offset in real time, as well as preset threshold ranges. Medical personnel can quickly grasp the operating status of the device through the display screen 13 without having to check each component individually, making operation convenient. The wireless communication module automatically establishes a Bluetooth connection with an external medical terminal to achieve real-time data transmission and remote control.

[0048] During treatment, when the displacement sensor of the protective structure detects that the acupuncture needle offset exceeds the preset threshold, or when the pressure sensor detects abnormal pressure, the control unit simultaneously triggers the emergency braking component and the warning component: the buzzer issues a graded buzzing warning, with intermittent buzzing when the pressure / offset is slightly abnormal and continuous buzzing when the abnormality is severe, and the indicator lights illuminate yellow and red lights respectively. This solves the shortcomings of existing devices that only brake without warning and make it difficult for medical staff to detect abnormalities in time. It can quickly remind medical staff to check for problems and prevent the abnormality from escalating.

[0049] Medical staff can receive abnormal warning information and operating parameters transmitted by the wireless communication module through an external terminal. Without on-site supervision, they can remotely send control commands to adjust acupuncture parameters or restart the device. The display screen 13 simultaneously displays the abnormality type and handling prompts, facilitating rapid troubleshooting by on-site personnel. After the abnormality is resolved, the control unit stops the warning component, the display screen 13 resumes displaying normal operating parameters, and the wireless communication module simultaneously sends feedback information about the abnormality being resolved to the external terminal.

[0050] Example 3:

[0051] As attached Figure 1 As shown, the difference from Embodiment 2 is that the device base 1 is provided with a limb fixation assembly, which includes an arc-shaped support plate 10 and an electric adjustment rod. The electric adjustment rod is fixedly connected to the device base 1, and the end of the electric adjustment rod away from the device base 1 is fixedly connected to the arc-shaped support plate 10. A medical flexible cushioning pad is detachably connected to the inner wall of the arc-shaped support plate 10. The electric adjustment rod is electrically connected to a control unit. The control unit is used to receive the limb posture signal fed back by the adaptive structural angle sensor and synchronously drive the electric adjustment rod to extend and retract, so as to realize the adaptive adjustment of the height of the arc-shaped support plate 10. Several ventilation holes are opened on the arc-shaped support plate 10, and the ventilation holes are evenly distributed on the arc-shaped support plate 10. The curved tray 10 is also equipped with a binding assembly, which includes a binding strap 11, Velcro and an adjusting buckle 12. The Velcro is fixedly connected to the binding strap 11. One end of the binding strap 11 is fixedly connected to one side of the curved tray 10. The adjusting buckle 12 is fixedly installed on the other side of the curved tray 10. The end of the binding strap 11 away from the curved tray 10 passes through the adjusting buckle 12 and is detachably glued to it by the Velcro.

[0052] The specific implementation process is as follows: After the device is activated, the limb fixation component is ready synchronously with the control unit. First, the medical flexible cushioning pad is attached to the inner wall of the arc-shaped support plate 10 to conform to the skin of the stroke patient's limb and reduce pressure discomfort. The patient places the limb to be treated on the arc-shaped support plate 10, and the medical staff pulls the binding strap 11 to pass it through the adjustment buckle 12 and fix it with Velcro. The tightness is adjusted by rotating the adjustment buckle 12 to adapt to the thickness of the patient's limb, avoiding being too tight and affecting blood circulation, or too loose and difficult to fix.

[0053] During treatment, the angle sensor of the adaptive structure detects the patient's limb posture deviation signal in real time and synchronously feeds it back to the control unit. The control unit drives the electric adjustment rod to extend and retract, causing the arc-shaped support plate 10 to adaptively adjust its height. This works in conjunction with the adaptive structure to ensure limb posture stability, allowing the acupuncture execution module to accurately align with acupoints. Ventilation holes on the arc-shaped support plate 10 provide real-time ventilation, preventing the limb from becoming stuffy and damp due to prolonged contact. The adaptive adjustment of the electric adjustment rod requires no manual operation, adapting to the limited limb movement characteristics of stroke patients. The medical flexible cushioning pad works in conjunction with the ventilation holes to improve patient comfort. The binding components are easy to disassemble and adapt to different limb sizes, demonstrating outstanding innovation and significantly improving the device's adaptability and treatment stability.

[0054] After treatment, unfasten the Velcro, remove the binding strap 11, and the control unit drives the electric adjustment rod to reset, returning the arc-shaped support plate 10 to its initial height. The medical flexible cushioning pad can be detached and disinfected for easy reuse.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation.
