Description

Technical Field

[0001] The invention relates to the technical field of obstetrics and gynecology rehabilitation equipment, and in particular discloses obstetrics and gynecology rehabilitation training equipment. Background Art

[0002] In the field of obstetrics and gynecology rehabilitation, pelvic floor muscle training is an important part of postpartum recovery, and has significant effects on improving pelvic floor muscle function and preventing urinary incontinence. However, traditional pelvic floor muscle training methods often rely on manual operation or simple equipment assistance, lack of scientificity and pertinence, and the training effect is difficult to quantify and evaluate. At the same time, the comfort and safety during training also need to be improved. Although some existing pelvic floor muscle training devices provide certain training functions, they often have shortcomings such as a single design, lack of intelligent adjustment mechanism, and inability to monitor physiological indicators in real time. For example, traditional training equipment may only provide fixed training trajectories and intensities, and cannot be personalized according to the user's physical condition and training needs. Summary of the invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a gynecological rehabilitation training device.

[0004] To achieve the above-mentioned purpose, a gynecological rehabilitation training device of the present invention comprises a fixing frame, a pelvic floor muscle trainer and a seat installed on the fixing frame, the pelvic floor muscle trainer is used in conjunction with the seat, the pelvic floor muscle trainer comprises a support frame, a first bracket, a second bracket, a first connecting member and a second connecting member respectively arranged on both sides of the support frame, one end of the first connecting member is installed on the support frame, and the end away from the support frame is connected to the first bracket to form a first sliding track, one end of the second connecting member is installed on the other side of the support frame away from the first connecting member, and the end of the second connecting member away from the support frame is connected to the second bracket to form a second sliding track, the pelvic floor muscle trainer also comprises a first sliding member and a second sliding member, the first sliding member is slidably arranged on the first connecting member, and the second sliding member is slidably arranged on the second connecting member; the user sits on the seat, steps on the first sliding member and the second sliding member with both feet respectively, and pushes the first sliding member and the second sliding member along the sliding track by the strength of the legs and buttocks to perform contraction and relaxation training of the pelvic floor muscles.

[0005] The user sits on the seat on the fixed frame, steps on the first and second sliding members with both feet, and pushes the sliding members along the sliding tracks (such as arc or linear paths) of the first connecting member and the second connecting member through the force of the legs and buttocks to reciprocate, thereby pulling the pelvic floor muscles to actively contract and relax. The rigid connection between the support frame and the two side brackets ensures the stability of the sliding track, and the dual-track independent motion mode can adapt to the force habits of different users to avoid muscle imbalance; this structure uses body movements to link pelvic floor muscle training, the operation is intuitive and conforms to the natural force mode, and is suitable for postpartum pelvic floor muscle recovery, combining safety, comfort and training efficiency.

[0006] The first sliding member and the second sliding member have the same structure. The sliding member includes a pedal, a rolling member and a limit member. A U-shaped groove is provided at the bottom of the pedal. The rolling member is accommodated in the U-shaped groove. The pedal is slidably arranged on the first connecting member or the second connecting member via the rolling member. The limit member includes a main body and a hook-shaped portion arranged on the main body. The main body is installed at the bottom of the pedal via a fastener. The hook-shaped portion is arranged under the connecting member to hook the connecting member to prevent the pedal from falling off.

[0007] This design achieves safe and reliable pelvic floor muscle training operation through the modular structure of the sliding part (pedal, rolling part, limiter). The user steps on the pedal of the sliding part with both feet, and the rolling part (such as roller or bearing) is embedded in the bottom U-shaped slot, so that the pedal can move smoothly along the surface of the first / second connecting part to reduce friction resistance; the hook-shaped part of the limiter hooks the connecting part from below, and the main body is fixed with the fastener to form a double anti-fall protection to ensure the stable connection between the pedal and the connecting part during exercise. This structure optimizes the sliding smoothness through rolling parts, and the limit hook design takes into account the training safety. It is especially suitable for dynamic load scenarios when the legs are exerting force to avoid the risk of derailment of the equipment. The double-sided sliding parts with the same structure simplify the production and assembly process, and support rapid maintenance and replacement, improving the overall durability of the equipment.

[0008] The rolling member includes an axle member installed on the pedal and a roller member rotatably arranged on the axle member. The roller member includes an arc-shaped sliding portion. The arc-shaped sliding portion is a hollow structure. A first mounting portion and a second mounting portion are arranged at both ends of the arc-shaped sliding portion. The first mounting portion and the second mounting portion are respectively built-in with ball bearings. The rolling member slides against the connecting member via the arc-shaped sliding portion.

[0009] The roller member of the rolling element slides in contact with the surface of the connecting member through a hollow arc-shaped sliding part. The first and second mounting parts at both ends are equipped with built-in ball bearings, so that the roller member can rotate around the shaft member with low friction, reducing mechanical losses when the pedal moves; the curved surface of the arc-shaped sliding part adapts to the contour of the connecting member to ensure that the sliding contact surface is evenly stressed and avoid local wear. When the user steps on the pedal, the arc-shaped sliding part of the roller member rolls in contact with the connecting member, and the smooth rotation of the ball bearing significantly reduces the movement resistance and improves the fluency and accuracy of training. The hook-shaped part of the limiter locks the connecting member from the bottom, and combined with the split shaft and roller design of the rolling member, it further prevents sliding deviation or falling off. This structure takes into account both lightness (hollow arc-shaped sliding part) and high strength, and is suitable for high-frequency rehabilitation training scenarios. The modular components are easy to disassemble and maintain, extending the service life of the equipment.

[0010] The fixing frame is also provided with a grip rod body, which includes an arc-shaped rod body, and a first grip part and a second grip part are bent from both ends of the arc-shaped rod body. The user can hold the first grip part and the second grip part with both hands, respectively, and stand with both feet on the first sliding member and the second sliding member respectively to move along the sliding track to perform pelvic floor muscle contraction and relaxation training.

[0011] By adding an ergonomic hand-grip rod and a lower limb sliding member linkage structure, the pelvic floor muscle training of the upper and lower limbs can be achieved. In the specific implementation, the user holds the first and second grips of the hand-grip rod with both hands (the bending angle is adapted to the natural gripping posture), steps on the sliding member pedal with both feet, stabilizes the core through arm support, and pushes the sliding member along the trajectory with leg force, driving the pelvic floor muscle group to contract and relax. The curved design of the arc rod reduces the static load on the upper limbs. The surface of the grip can be coated with a non-slip silicone layer and supports angle fine-tuning to adapt to different arm span requirements; the rod body is rigidly connected to the fixed frame to ensure body balance during training and avoid the risk of slipping. The lower limb sliding member ensures smooth sliding and anti-falling through the ball bearing and limit hook structure of the rolling member. Combined with the two-way support of the hand-grip rod, a coordinated training mode of "upper limb stability-lower limb force" is formed, which is especially suitable for users with weak postpartum muscle strength or insufficient balance ability, while reducing the risk of falling and improving the efficiency of pelvic floor muscle activation. The overall design takes into account both functionality and safety, and is suitable for multi-stage rehabilitation needs.

[0012] With the addition of a hand-grip rod, users can not only sit on the chair for rehabilitation training, but also stand for training in the later stage. In the sitting training stage, the user sits on the chair, holds the rod with both hands to stabilize the core, and pushes the slider with both feet to train the pelvic floor muscles; when switching to a standing position in the later stage of rehabilitation, the user stands on the pedal slider, adjusts the body's center of gravity with both hands through the grip, and simultaneously uses the strength of the legs and hips to drive the slider to move, strengthening the dynamic contraction of the pelvic floor muscles. It not only lowers the threshold for initial training, but also supports advanced training after muscle strength is improved, improving the applicability of the equipment and rehabilitation efficiency.

[0013] The arc-shaped sliding part has an embedded piezoelectric film sensor array for detecting the pressure distribution of the sliding contact surface in real time. The ball bearings of the first mounting part and the second mounting part are respectively connected to micro servo motors. The micro servo motors dynamically adjust the preload force of the ball bearings according to the pressure distribution data to balance the force exerted on both sides by the user.

[0014] The piezoelectric film sensor array embedded in the arc-shaped sliding part collects the pressure distribution data of the contact surface between the sliding part and the connecting part in real time, and transmits it to the control module synchronously; the ball bearings of the first and second mounting parts are respectively connected to micro servo motors, and the preload force of the bearings on both sides is automatically adjusted based on the difference in pressure distribution (such as excessive force on one side): when it is detected that the left side is too strong, the servo motor on the left side increases the bearing damping to balance the resistance, and the damping on the right side is reduced to compensate for the weak side of the muscle force, thereby dynamically correcting the problem of uneven force on both sides. This design avoids muscle compensation or sports injuries during training through the "sensing-feedback-adjustment" closed-loop control, and is particularly suitable for the progressive rehabilitation of patients with postpartum muscle imbalance. At the same time, the sensor data can be synchronized to the terminal to generate a visual training report to guide users to optimize the action mode. The intelligent resistance adjustment of the sliding part is combined with the multi-posture support of the hand-grip rod body, taking into account the biomechanical adaptability in the sitting / standing mode, and significantly improving the safety, scientificity and personalization of training.

[0015] The outer side of the seat is also coated with a composite coating, which includes a nano-silver coating coated on the outer side of the seat and a photocatalytic titanium dioxide layer coated on the outer side of the nano-silver coating. The nano-silver coating is used to inhibit the growth of external bacteria on the seat, and the photocatalytic titanium dioxide layer can decompose organic dirt on the seat under UV LED irradiation.

[0016] The dual protection design of the seat composite coating (nano-silver coating + photocatalytic titanium dioxide layer) achieves long-lasting antibacterial and self-cleaning functions. In specific implementation, the nano-silver coating is directly applied to the seat surface, and the broad-spectrum antibacterial properties of silver ions are used to inhibit the growth of bacteria and fungi; the outer titanium dioxide coating decomposes sweat, grease and other organic pollutants through photocatalytic reactions under the irradiation of the built-in UV LED light source of the fixed frame, reducing the use of chemical detergents. The UV LED can be triggered by timing or manually by the user to ensure that the self-cleaning process is efficient and controllable. The composite coating and the antibacterial and breathable material of the seat work together to form a multi-level hygienic barrier of "active antibacterial-photocatalytic decomposition-physical protection", which is especially suitable for frequently used medical scenarios to reduce the risk of cross-infection. The coating material is non-toxic, environmentally friendly, wear-resistant and corrosion-resistant, adapted to the dynamic friction in sitting / standing training, ensuring hygienic safety under long-term use, while reducing equipment maintenance costs, improving user experience and medical compliance.

[0017] The seat also includes an angle adjuster arranged at the rear of the seat and a height adjuster arranged at the bottom of the seat. The user can adjust the height and tilt angle of the seat according to his or her own height and comfort requirements. The angle adjuster and micro servo motor of the seat are electrically connected to the external control center. When the user adjusts the seat angle, the external control center controls the micro servo motor according to the adjustment data to adjust the ball bearing preload.

[0018] The seat's angle adjuster (such as hydraulic or gear structure) and height adjuster (such as gas spring or screw mechanism) allow users to adjust the seat's inclination and height according to their body shape and training stage, optimizing the biomechanical line of the sitting posture; when the seat's angle or height changes, the external control center automatically links the micro-servo motor based on the adjustment data (such as inclination sensor feedback), and adjusts the preload of the ball bearings on both sides in real time (for example, increasing resistance to match the center of gravity shift when the seat reclines), ensuring the resistance adaptability of pelvic floor muscle training in different postures. This design uses "posture-resistance" closed-loop control to avoid force deviation caused by changes in body position, improving the scientificity and comfort of training.

[0019] The pedal is also provided with an adjustable arch support module, which includes a sliding guide rail arranged along the length direction of the pedal, a sliding support block arranged on the sliding guide rail, an electromagnet embedded in the sliding support block, a pressure sensor is provided at the joint between the sliding support block and the arch of the foot, and the sliding guide rail is made of magnetic conductive material. When the pressure in the arch area is less than a preset value, the sliding support block automatically moves forward. When the pressure in the arch area is equal to the preset value, the external control center is energized to cause the electromagnet to attract the sliding guide rail and lock the position of the sliding support block.

[0020] The intelligent dynamic adjustment function of the arch support module realizes adaptive balance and precise positioning of foot pressure. When the user steps on the pedal, the pressure sensor monitors the force applied to the arch fitting area in real time. If the pressure is detected to be lower than the preset threshold (such as insufficient arch support), the external control center drives the sliding support block to move forward along the magnetic sliding rail until the pressure reaches the standard; when the pressure reaches the preset value, the electromagnet is energized to adsorb the rail and instantly lock the position of the support block to prevent sliding deviation. This module dynamically adapts to different arch curvatures and force application habits through the closed-loop control of "real-time monitoring-automatic adjustment-magnetic locking", avoiding foot fatigue or posture compensation caused by insufficient support during training, and reducing manual adjustment operations. The magnetic properties of the sliding rail and the rapid response design of the electromagnet ensure support stability. Combined with the seat angle / height adjustment and ball bearing resistance linkage, a coordinated biomechanical adaptation from the foot to the pelvic floor muscle group is formed, further improving the training accuracy and comfort. This module can be expanded to independent regulation on both sides to adapt to the differences between the left and right arches, and enhance the individualization and safety of rehabilitation training.

[0021] The first grip part and the second grip part are both covered with an anti-slip cover, and the anti-slip cover includes a silicone lining layer that is interference fit with the grip part, and the outer side of the silicone lining layer is provided with an anti-slip texture with staggered protrusions, and the outer side of the first grip part and the second grip part are provided with a protruding annular strip, and the anti-slip cover is provided with an annular groove used in conjunction with the protruding annular strip.

[0022] The silicone lining is tightly wrapped around the surface of the first and second grips through interference fit, and the inner annular groove is nested and engaged with the protruding annular strip of the grip, forming a double anti-slip fixing mechanism to prevent the anti-slip sleeve from rotating or falling off during training; the staggered raised anti-slip texture on the outside increases the friction coefficient of the palm contact surface, effectively preventing the hand from slipping, especially during sweating or high-intensity training. The flexibility of the silicone material adapts to different hand shapes and relieves fatigue from long-term gripping, while the surface texture is easy to clean and maintain. This design combines the arc-shaped support of the grip rod with the intelligent adjustment function of the foot slider to form a collaborative training system of "upper limb anti-slip-lower limb dynamic adaptation", which is especially suitable for users with weak postpartum muscle strength or insufficient hand grip, ensuring the safety and operational accuracy of the entire rehabilitation training process.

[0023] The seat is equipped with a heart rate monitoring sensor and a body temperature monitoring sensor to monitor the user's physiological indicators in real time. The heart rate monitoring sensor adopts a photoelectric PPG module, and the body temperature monitoring sensor adopts an infrared non-contact probe. Both are communicated with an external control center; when abnormal heart rate or body temperature data is detected, the external control center triggers an audible and visual alarm and suspends the movement of the sliding part.

[0024] Photoelectric PPG modules (such as green LEDs and photoelectric sensors) are embedded in the seat contact surface to continuously monitor the user's heart rate through photoplethysmography; infrared non-contact probes (such as thermopile sensors) detect body surface temperature in a directional manner, and both data are transmitted to the external control center in real time. When the heart rate exceeds the threshold (such as >140bpm) or the body temperature is abnormal (such as >38°C), the system immediately triggers an audible and visual alarm (such as a warning light and a buzzer), cuts off the driving power of the slider or activates the electromagnetic brake to lock the slider, and forcibly stops the training to prevent accidents. The sensor data is uploaded to the terminal synchronously to generate a health log for medical staff to evaluate the rehabilitation process. This design deeply couples physiological indicator monitoring with equipment motion control to form a fully closed-loop safety protection system of "abnormal perception-active braking-data traceability", which is especially suitable for users with weak physical condition or potential health risks after childbirth. While ensuring the intensity of training, it avoids the risk of cardiovascular overload and improves the safety redundancy and emergency response capabilities of medical-grade rehabilitation equipment.

[0025] The beneficial effects of the present invention are as follows: through the dual-track design of the sliding part combined with intelligent sensing and dynamic resistance control, multi-dimensional coordinated training of the pelvic floor muscles can be achieved: the legs and buttocks are used to drive the sliding part to move along the preset track, directly activating the contraction and relaxation of the pelvic floor muscles; the piezoelectric film sensor monitors the pressure distribution in real time, and the micro-servo motor is linked to dynamically balance the bilateral resistance to correct muscle imbalance; the arch support module intelligently adapts to the foot pressure, and combines the seat angle / height adjustment with the stable support of the hand-grip rod to form a biomechanical closed loop of coordinated force between the upper and lower limbs. At the same time, nanosilver and photocatalytic coatings achieve self-cleaning and antibacterial properties, and the heart rate and body temperature monitoring system triggers emergency braking to build an integrated "training-protection-monitoring" system. The equipment significantly improves the accuracy and safety of training, reduces the user's operating threshold through adaptive adjustment, and expands the adaptability of the rehabilitation stage by combining the sit / stand dual mode. It has both high efficiency, hygiene and medical-grade safety redundancy to meet the personalized and scientific needs of postpartum rehabilitation. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0040] See also Figures 1 to 11 As shown, a gynecological rehabilitation training device of the present invention comprises a fixing frame 1, a pelvic floor muscle trainer 3 and a seat 2 installed on the fixing frame 1, wherein the pelvic floor muscle trainer 3 is used in conjunction with the seat 2, and the pelvic floor muscle trainer 3 comprises a support frame 4, a first bracket 5, a second bracket 6, a first connecting member 7 and a second connecting member 8 respectively arranged on both sides of the support frame 4, one end of the first connecting member 7 is installed on the support frame 4, and the end away from the support frame 4 is connected to the first bracket 5 to form a first sliding track 9, and one end of the second connecting member 8 is installed on the other side of the support frame 4 away from the first connecting member 7 On the upper part, one end of the second connecting member 8 away from the supporting frame 4 is connected to the second bracket 6 to form a second sliding track 11, and the pelvic floor muscle trainer 3 also includes a first sliding member 12 and a second sliding member 13, the first sliding member 12 is slidably set on the first connecting member 7, and the second sliding member 13 is slidably set on the second connecting member 8; the user sits on the seat 2, steps on the first sliding member 12 and the second sliding member 13 with both feet respectively, and pushes the first sliding member 12 and the second sliding member 13 along the sliding track through the strength of the legs and buttocks to perform pelvic floor muscle contraction and relaxation training.

[0041] The user sits on the seat 2 on the fixed frame 1, steps on the first and second sliding members 13 with both feet, and pushes the sliding members along the sliding tracks (such as arc or linear paths) of the first connecting member 7 and the second connecting member 8 through the force of the legs and buttocks to reciprocate, thereby pulling the pelvic floor muscles to actively contract and relax. The rigid connection between the support frame 4 and the two side brackets ensures the stability of the sliding track, and the dual-track independent motion mode can adapt to the force habits of different users to avoid muscle imbalance; this structure uses body movements to link pelvic floor muscle training, the operation is intuitive and conforms to the natural force mode, and is suitable for postpartum pelvic floor muscle recovery, combining safety, comfort and training efficiency.

[0042] The first sliding member 12 and the second sliding member 13 have the same structure, and the sliding member includes a pedal 14, a rolling member 15 and a limit member 16. A U-shaped groove 17 is provided at the bottom of the pedal 14, and the rolling member 15 is accommodated in the U-shaped groove 17. The pedal 14 is slidably set on the first connecting member 7 or the second connecting member 8 via the rolling member 15. The limit member 16 includes a main body 18 and a hook portion 19 arranged on the main body 18. The main body 18 is installed at the bottom of the pedal 14 via a fastener, and the hook portion 19 is arranged under the connecting member to hook the connecting member to prevent the pedal 14 from falling off.

[0043] This design achieves safe and reliable pelvic floor muscle training operation through the modular structure of the sliding part (pedal 14, rolling part 15, and limiter 16). The user steps on the pedal 14 of the sliding part with both feet, and the rolling part 15 (such as a roller or a bearing) is embedded in the bottom U-shaped slot 17, so that the pedal 14 can move smoothly along the surface of the first / second connecting part 8 to reduce friction resistance; the hook-shaped portion 19 of the limiter 16 hooks the connecting part from below, and combines with the fastener to fix the main body 18 to form a double anti-fall protection to ensure the stable connection between the pedal 14 and the connecting part during exercise. This structure optimizes the sliding smoothness through the rolling part 15, and the limit hook design takes into account the training safety. It is especially suitable for dynamic load scenarios when the legs are exerting force to avoid the risk of derailment of the equipment. The double-sided sliding parts with the same structure simplify the production and assembly process, support rapid maintenance and replacement, and improve the overall durability of the equipment.

[0044] The rolling member 15 includes an axle member 21 installed on the pedal 14 and a roller member 22 rotatably set on the axle member 21. The roller member 22 includes an arc-shaped sliding portion 23. The arc-shaped sliding portion 23 is a hollow structure. A first mounting portion 24 and a second mounting portion 25 are provided at both ends of the arc-shaped sliding portion 23. The first mounting portion 24 and the second mounting portion 25 are respectively built with ball bearings 26. The rolling member 15 slides against the connecting member via the arc-shaped sliding portion 23.

[0045] The roller member 22 of the rolling member 15 slides in contact with the surface of the connecting member through the hollow arc-shaped sliding portion 23. The first and second mounting portions 25 at both ends are equipped with ball bearings 26, so that the roller member 22 can rotate around the shaft member 21 with low friction, reducing the mechanical loss when the pedal 14 moves; the curved surface of the arc-shaped sliding portion 23 adapts to the contour of the connecting member to ensure that the sliding contact surface is evenly stressed and avoid local wear. When the user steps on the pedal 14, the arc-shaped sliding portion 23 of the roller member 22 rolls in contact with the connecting member, and the smooth rotation of the ball bearing 26 significantly reduces the movement resistance and improves the fluency and accuracy of training. The hook portion 19 of the limiter 16 locks the connecting member from the bottom, and combined with the split shaft and roller design of the rolling member 15, it further prevents sliding deviation or falling off. This structure takes into account both light weight (hollow arc-shaped sliding portion 23) and high strength, and is suitable for high-frequency rehabilitation training scenarios. The modular components are easy to disassemble and maintain, extending the service life of the equipment.

[0046] The fixing frame 1 is also provided with a hand grip rod 27, which includes an arc-shaped rod 28, and a first grip portion 29 and a second grip portion 31 are bent from both ends of the arc-shaped rod 28. The user can hold the first grip portion 29 and the second grip portion 31 with both hands, respectively, and stand with both feet on the first sliding member 12 and the second sliding member 13 respectively to move along the sliding track to perform pelvic floor muscle contraction and relaxation training.

[0047] By adding an ergonomic hand-grip rod 27 and a linkage structure of a lower limb slide, the pelvic floor muscle training of the upper and lower limbs can be achieved. In the specific implementation, the user holds the first and second gripping parts 31 of the hand-grip rod 27 with both hands (the bending angle is adapted to the natural gripping posture), steps on the sliding part pedal 14 with both feet, stabilizes the core through arm support, and pushes the sliding part along the trajectory with the leg force, driving the pelvic floor muscle group to contract and relax. The curved design of the arc rod 28 reduces the static load on the upper limbs. The surface of the grip part can be coated with a non-slip silicone layer and support angle fine-tuning to adapt to different arm span requirements; the rod body is rigidly connected to the fixed frame 1 to ensure body balance during training and avoid the risk of slipping. The lower limb slide ensures smooth sliding and anti-falling through the ball bearing 26 and the limit hook structure of the rolling part 15. Combined with the two-way support of the hand-grip rod 27, a coordinated training mode of "upper limb stability-lower limb force" is formed, which is particularly suitable for users with weak muscle strength or insufficient balance after childbirth, while reducing the risk of falling and improving the efficiency of pelvic floor muscle activation. The overall design takes into account both functionality and safety, and is suitable for multi-stage rehabilitation needs.

[0048] With the addition of a hand-grip rod 27, the user can not only sit on the seat 2 for rehabilitation training, but also stand for training in the later stage. In the sitting training stage, the user sits on the seat 2, holds the rod with both hands to stabilize the core, and pushes the sliding member with both feet to train the pelvic floor muscles; when switching to a standing position in the later stage of rehabilitation, the user stands on the pedal 14 sliding member, adjusts the body's center of gravity with both hands through the gripping part, and simultaneously uses the strength of the legs and hips to drive the sliding member to move, strengthening the dynamic contraction of the pelvic floor muscles. It not only reduces the initial training threshold, but also supports advanced training after muscle strength is improved, improving the applicability of the equipment and rehabilitation efficiency.

[0049] The arc-shaped sliding part 23 has an embedded piezoelectric film sensor array 32 for real-time detection of the pressure distribution of the sliding contact surface. The ball bearings 26 of the first mounting part 24 and the second mounting part 25 are respectively connected to micro servo motors 33. The micro servo motor 33 dynamically adjusts the preload of the ball bearings 26 according to the pressure distribution data to balance the force exerted on both sides by the user.

[0050] The piezoelectric film sensor array 32 embedded in the arc-shaped sliding part 23 collects the pressure distribution data of the contact surface between the sliding part and the connecting part in real time, and transmits it to the control module synchronously; the ball bearings 26 of the first and second mounting parts 25 are respectively connected to the micro servo motors 33, and the preload force of the bearings on both sides is automatically adjusted based on the difference in pressure distribution (such as excessive force on one side): when it is detected that the left side is too strong, the servo motor on the left side increases the bearing damping to balance the resistance, and the damping on the right side is reduced to compensate for the weak side of the muscle force, thereby dynamically correcting the problem of uneven force on both sides. This design avoids muscle compensation or sports injuries during training through the closed-loop control of "sensing-feedback-regulation", and is particularly suitable for the progressive rehabilitation of patients with postpartum muscle imbalance. At the same time, the sensor data can be synchronized to the terminal to generate a visual training report to guide users to optimize the action mode. The intelligent resistance adjustment of the sliding part is combined with the multi-posture support of the hand-grip rod body 27, taking into account the biomechanical adaptability in the sitting / standing mode, and significantly improving the safety, scientificity and personalization of training.

[0051] The outer side of the seat 2 is also coated with a composite coating 34, which includes a nano-silver coating 35 coated on the outer side of the seat 2 and a photocatalytic titanium dioxide layer 36 coated on the outer side of the nano-silver coating 35. The nano-silver coating 35 is used to inhibit the growth of external bacteria on the seat 2, and the photocatalytic titanium dioxide layer 36 can decompose organic dirt on the seat 2 under UV LED irradiation.

[0052] The double protection design of the composite coating 34 of the seat 2 (nano-silver coating 35 + photocatalytic titanium dioxide layer 36) achieves long-term antibacterial and self-cleaning functions. In specific implementation, the nano-silver coating 35 is directly applied to the surface of the seat 2, and the broad-spectrum antibacterial properties of silver ions are used to inhibit the growth of bacteria and fungi; the outer titanium dioxide coating is irradiated by the built-in UV LED light source of the fixed frame 1, and decomposes sweat, grease and other organic pollutants through photocatalytic reactions, reducing the use of chemical detergents. The UV LED can be triggered by timing or by the user manually to ensure that the self-cleaning process is efficient and controllable. The composite coating 34 and the antibacterial and breathable material of the seat 2 work together to form a multi-level hygienic barrier of "active antibacterial-photocatalytic decomposition-physical protection", which is especially suitable for frequently used medical scenarios to reduce the risk of cross infection. The coating material is non-toxic, environmentally friendly, wear-resistant and corrosion-resistant, adapted to the dynamic friction in sitting / standing training, ensuring hygienic safety under long-term use, while reducing equipment maintenance costs, improving user experience and medical compliance.

[0053] The seat 2 also includes an angle adjuster 37 arranged at the rear of the seat 2 and a height adjuster 38 arranged at the bottom of the seat 2. The user can adjust the height and tilt angle of the seat 2 according to his or her own height and comfort requirements. The angle adjuster 37 of the seat 2 and the micro servo motor 33 are both electrically connected to the external control center. When the user adjusts the angle of the seat 2, the external control center controls the micro servo motor 33 according to the adjustment data to adjust the preload force of the ball bearing 26.

[0054] The angle adjuster 37 (such as hydraulic or gear structure) and the height adjuster 38 (such as gas spring or screw mechanism) of the seat 2 support the user to adjust the inclination and height of the seat 2 according to the body shape and training stage, and optimize the biomechanical line of the sitting posture; when the angle or height of the seat 2 changes, the external control center automatically links the micro servo motor 33 based on the adjustment data (such as the feedback from the inclination sensor), and adjusts the preload force of the ball bearings 26 on both sides in real time (for example, when the seat 2 reclines, the resistance is increased to match the center of gravity offset), ensuring the resistance adaptability of pelvic floor muscle training in different postures. This design avoids force deviation caused by changes in body position through "posture-resistance" closed-loop control, improving the scientificity and comfort of training.

[0055] The pedal 14 is also provided with an adjustable arch support module 39, which includes a sliding guide rail 41 arranged along the length direction of the pedal 14, and a sliding support block 42 arranged on the sliding guide rail 41. The sliding support block 42 has an electromagnet embedded in it, and a pressure sensor 43 is provided at the joint between the sliding support block 42 and the arch of the foot. The sliding guide rail 41 is made of magnetic conductive material. When the pressure in the arch area is less than a predetermined value, the sliding support block 42 automatically moves forward. When the pressure in the arch area is equal to the predetermined value, the external control center is energized to cause the electromagnet to attract the sliding guide rail 41 and lock the position of the sliding support block 42.

[0056] The intelligent dynamic adjustment function of the arch support module realizes adaptive balance and precise positioning of foot pressure. When the user steps on the pedal 14, the pressure sensor 43 monitors the force applied to the arch fitting area in real time. If the pressure is detected to be lower than the preset threshold (such as insufficient arch support), the external control center drives the sliding support block 42 to move forward along the magnetic sliding guide rail 41 until the pressure reaches the standard; when the pressure reaches the preset value, the electromagnet is energized to adsorb the guide rail and instantly lock the position of the support block to prevent sliding deviation. This module dynamically adapts to different arch curvatures and force application habits through the closed-loop control of "real-time monitoring-automatic adjustment-magnetic locking", avoiding foot fatigue or posture compensation caused by insufficient support during training, and reducing manual adjustment operations. The magnetic properties of the sliding guide rail 41 and the rapid response design of the electromagnet ensure the stability of support. Combined with the angle / height adjustment of the seat 2 and the resistance linkage of the ball bearing 26, a coordinated biomechanical adaptation from the foot to the pelvic floor muscles is formed, further improving the training accuracy and comfort. This module can be expanded to independent bilateral regulation to adapt to the differences in left and right arches, and enhance the individualization and safety of rehabilitation training.

[0057] The first grip portion 29 and the second grip portion 31 are both covered with an anti-slip sleeve 44, and the anti-slip sleeve 44 includes a silicone lining layer that is interference fit with the grip portion, and the outer side of the silicone lining layer is provided with staggered raised anti-slip textures, and the outer sides of the first grip portion 29 and the second grip portion 31 are provided with protruding annular strips 46, and the anti-slip sleeve 44 is provided with an annular groove 47 used in conjunction with the protruding annular strip 46.

[0058] The silicone lining layer is tightly wrapped around the surface of the first and second gripping parts 31 through interference fit, and the inner annular groove 47 is nested and engaged with the protruding annular strip 46 of the gripping part to form a double anti-slip fixing mechanism to prevent the anti-slip sleeve 44 from rotating or falling off during training; the staggered raised anti-slip texture on the outside increases the friction coefficient of the palm contact surface, which effectively prevents the hand from slipping, especially when sweating or high-intensity training. The flexibility of the silicone material adapts to different hand shapes and relieves fatigue from long-term gripping. At the same time, the surface texture is easy to clean and maintain. This design combines the arc-shaped support of the hand grip rod 27 with the intelligent adjustment function of the foot slide to form a collaborative training system of "upper limb anti-slip-lower limb dynamic adaptation", which is especially suitable for users with weak postpartum muscle strength or insufficient hand gripping power, ensuring the safety and operation accuracy of the entire rehabilitation training process.

[0059] The seat 2 is equipped with a heart rate monitoring sensor 48 and a body temperature monitoring sensor 49 to monitor the user's physiological indicators in real time. The heart rate monitoring sensor 48 adopts a photoelectric PPG module, and the body temperature monitoring sensor 49 adopts an infrared non-contact probe. Both are connected to the external control center for communication; when abnormal heart rate or body temperature data is detected, the external control center triggers an audible and visual alarm and suspends the movement of the sliding part.

[0060] The photoelectric PPG module (such as green light LED and photoelectric sensor) is embedded in the contact surface of the seat 2, and the user's heart rate is continuously monitored by photoplethysmography; the infrared non-contact probe (such as thermopile sensor) detects the body surface temperature in a directional manner, and the data of both are transmitted to the external control center in real time. When the heart rate exceeds the threshold (such as >140bpm) or the body temperature is abnormal (such as >38℃), the system immediately triggers an audible and visual alarm (such as a warning light and a buzzer), cuts off the driving power of the sliding part or activates the electromagnetic brake to lock the sliding part, and forcibly stops the training to prevent accidents. The sensor data is synchronously uploaded to the terminal to generate a health log for medical staff to evaluate the rehabilitation process. This design deeply couples physiological indicator monitoring with equipment motion control to form a fully closed-loop safety protection system of "abnormal perception-active braking-data traceability", which is especially suitable for users with weak physical condition or potential health risks after childbirth. While ensuring the intensity of training, it avoids the risk of cardiovascular overload and improves the safety redundancy and emergency response capabilities of medical-grade rehabilitation equipment.
