Description

Technical Field

[0001] This invention relates to the field of rehabilitation training equipment technology, specifically to a postpartum pelvic floor muscle rehabilitation training device based on pressure sensing in obstetrics and gynecology. Background Technology

[0002] The pelvic floor muscles are a group of muscles that close the bottom of the pelvis. They resemble an elastic trellis, supporting the pelvic organs such as the urethra, bladder, vagina, uterus, and rectum, maintaining their normal physiological positions and ensuring proper functioning. During pregnancy and childbirth, the pelvic floor muscles bear the pressure of the enlarged uterus for an extended period. Simultaneously, to adapt to the demands of childbirth, the pelvic floor muscles and fascia undergo physiological expansion, leading to a significant decrease in muscle elasticity and even rupture of some muscle fibers. This weakens the supporting function of the pelvic floor muscles postpartum, making it a common cause of pelvic floor dysfunction.

[0003] Timely and standardized postpartum rehabilitation exercises are crucial for improving pelvic floor muscle function. Through scientific rehabilitation training, damaged pelvic floor muscles can gradually recover to near their pre-pregnancy state, effectively reducing the risk of pelvic organ prolapse, urinary incontinence, and other pelvic floor dysfunction disorders, which is of great significance for ensuring the quality of life of postpartum women. Therefore, postpartum pelvic floor muscle rehabilitation training has become one of the core needs in the field of postpartum rehabilitation, and various auxiliary training devices have emerged accordingly.

[0004] Currently, postpartum pelvic floor muscle training equipment on the market is mainly resistance training equipment. This involves the calves moving a plate to compress springs, causing the legs to flex and extend. The spring force then compresses the thighs to train the pelvic floor muscles. However, this type of equipment has significant technical limitations. Because it uses a single, fixed resistance setting, it cannot be personalized according to the different postpartum recovery stages and pelvic floor muscle strength levels of different users. For users with weak muscles, the fixed resistance may exceed their muscle tolerance, exacerbating muscle damage. For users whose muscle strength has recovered to some extent, the fixed resistance is insufficient to achieve an effective training intensity, resulting in poor training effects and failing to fully meet the personalized rehabilitation needs of different users. Therefore, those skilled in the art have proposed a pressure-sensor-based postpartum pelvic floor muscle rehabilitation training device to solve the aforementioned technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a pressure-sensing-based postpartum pelvic floor muscle rehabilitation training device for obstetrics and gynecology, which solves the problem that the fixed resistance of existing training equipment is difficult to adapt to the needs of users at different stages of rehabilitation training.

[0018] Preferably, the multidimensional collaborative mechanism further includes a pulse generator, with a pulse generator provided on one side of the bottom center of the training bed and an overcurrent and overvoltage protector provided on the other side of the bottom center of the training bed.

[0019] Working Principle: After childbirth, to aid in the recovery of the pelvic floor muscles, postpartum women undergo pelvic floor muscle rehabilitation training in stages. First, the rhythmic assist mechanism is activated. In the initial stage of rehabilitation training, the user often coordinates their breathing to control the contraction and relaxation of the muscles surrounding the pelvic floor. The user lies flat on the training bed, and a positioning pillow helps position their body. The user then uses a timer display on the mounting base to set a timer or reminder, coordinating their breathing with the count or prompts on the display to control the contraction and relaxation of the muscles surrounding the pelvic floor. As a further step in the breathing-coordinated rehabilitation training stage, the user can hold the stretching rings and pull them synchronously during breathing exercises. The movement of the stretching rings moves the sliding seat on the mounting frame, stretching the elastic band between the sliding seat and the fixed seat. After stretching to a certain extent, the elastic band returns the sliding seat and the stretching rings at the bottom of the mounting frame to their original position. The user then continues this process while breathing. Simultaneously, the use of the tension equipment engages the upper body muscles in coordination with the gluteal muscles, thereby enhancing the training effect on the pelvic floor muscles. After reaching a certain intensity, the user begins the finishing training phase of the initial training. The user lies flat on the training bed again, closes their eyes, and grips the ball seat tightly. This allows the air inside the ball seat to flow through the rubber connecting tube into the rubber elastic ball. Simultaneously, the user inhales, and as the air flows from the ball seat into the rubber elastic ball through the rubber connecting tube... The body compresses the one-way seat on the mounting ring, causing the one-way seat to fully open, allowing the air inside the hand-held ball seat to smoothly enter the rubber elastic ball. When the hand-held ball seat becomes flat, the user releases their hands from the ball seat and exhales simultaneously. At this time, due to the air pressure inside the rubber elastic ball, the air inside the rubber elastic ball slowly flows back to the hand-held ball seat through the reflux micropores on the one-way seat, causing the hand-held ball seat to return to its original shape, thus completing one training cycle. By repeating the above operation, the breathing-assisted training of the early stage of pelvic floor muscle can be completed.Then, the advanced training mechanism is activated. Once the user has completed the initial rehabilitation training, or their physical condition is suitable for the intermediate and later stages of training, the user first adjusts the angle adjustment seat on the training bed to a suitable angle for their posture. Then, the user adjusts their body position so that the inner thighs are in contact with the grooves on the fitting seat. Next, the user clamps their thighs together, causing the fitting seat on the mounting column to move inwards synchronously. Simultaneously, the fitting seat rotates the rotating ring seat on the mounting column. Once the designated angle is reached, the torsion spring on the rotating ring seat returns it and the fitting seat to their original position, completing one training cycle. When the user's thighs move the fitting seat, the fitting seat also simultaneously engages the adductor muscles of the thigh, i.e., the adductor muscles. Since the adductor muscles and pelvic floor muscles have a synergistic effect in body structure, clamping the legs directly triggers active contraction of the pelvic floor muscles, simulating the core contraction-relaxation movement of Kegel exercises, thus achieving advanced training for the user. Simultaneously, the dynamic adjustment mechanism is activated. When a user undergoes pelvic floor muscle rehabilitation training at an advanced training institution, the pressure sensor on the fitting seat synchronously monitors the user's pressure data and transmits it to the PID controller. When the pressure data transmitted from the pressure sensor exceeds a set threshold, it indicates that the user's physical condition or rehabilitation level does not meet the current training requirements. At this time, the PID controller reduces the current intensity of the electromagnetic coil seat on the mounting column, thereby reducing the number of magnetic particles in the magnetic suspension fluid in the concave cavity that adhere to the corresponding position on the outer wall of the mounting column. This reduces the friction force on the outer wall of the mounting column when the fitting seat drives the rotating ring seat on the mounting column to rotate. Conversely, the PID controller controls and increases the current intensity of the electromagnetic coil seat, thereby increasing the number of magnetic particles in the magnetic suspension fluid in the concave cavity that adhere to the corresponding position on the outer wall of the mounting column. This increases the resistance of the rotating ring seat and the fitting seat during rotation, thus achieving dynamic adjustment of the resistance during the user's rehabilitation training.Afterwards, the multidimensional synergistic mechanism is activated. After each of the above training sessions, the user lies flat on the training bed and begins the final synergistic training. First, the user's lower back, hips, and corresponding pelvic floor muscles are matched with the flexible electrode holders and positioning seats on the matching platform. At this time, the PID controller collects the user's resting electromyographic baseline data through the electromyography sensor. Then, the subsequent synergistic training phase is divided into two stages: passive electrical stimulation awakening and active contraction synergy. When in the passive stage, the PID controller outputs low-frequency pulses to the flexible electrode holders on the matching platform through the pulse generator based on the electromyographic baseline data transmitted from the electromyography sensor. The system stimulates the user's pelvic floor muscle fibers to passively contract, awakening damaged nerves and muscles. During the active phase, the PID controller controls the timing display on the mounting base to issue an active contraction command. The user voluntarily contracts their pelvic floor muscles, and an electromyography (EMG) sensor collects EMG signals in real time during the contraction process. The PID controller analyzes the amplitude and frequency characteristics of the EMG signals to determine the effectiveness of the contraction. Simultaneously, it dynamically adjusts the output parameters of the pulse generator to avoid over-reliance on passive stimulation. Overcurrent and overvoltage protectors monitor the electrical stimulation current and voltage in real time, immediately cutting off the output in case of abnormalities to ensure training safety. This achieves a multi-dimensional, synergistic training effect for the user.

[0020] This invention provides a pressure-sensor-based postpartum pelvic floor muscle rehabilitation training device for obstetrics and gynecology. It has the following beneficial effects:

[0021] 1. This invention, by adding and setting a rhythm-assisted mechanism, provides intuitive breathing rhythm reminders through a timing display screen during postpartum pelvic floor muscle rehabilitation training. This helps postpartum women accurately control the timing of pelvic floor muscle contraction and relaxation, quickly establishing a sense of linkage between breathing and pelvic floor muscle movement, and avoiding ineffective training due to rhythm confusion. On the other hand, the combination of the hand-held ball seat and the rubber elastic ball further enhances the synergy between breathing and pelvic floor muscle contraction through tactile feedback. At the same time, the one-way reflux structure ensures stable gas return, helping postpartum women accurately control the intensity of force exertion. The combination of the stretching ring and elastic band can drive the upper body muscles and gluteal muscle groups to move in synergy, which not only enriches the early training methods but also improves the overall effect of pelvic floor muscle training, adapting to the rehabilitation needs of weak muscles in the early postpartum period.

[0022] 2. This invention, by adding and setting an advanced training mechanism, allows users to perform postpartum pelvic floor muscle rehabilitation training. The mechanism not only achieves precise fit and positioning of the inner thighs through the fitting groove of the seat, making the leg-clamping movement more standardized, but also directly triggers active contraction of the pelvic floor muscles by leveraging the structural synergy between the adductor muscles and pelvic floor muscles, accurately simulating the core movements of Kegel exercises, laying the foundation for mid-to-late stage rehabilitation training. Furthermore, the angle-adjustable seat can adapt to different postpartum body postures, and multiple automatically resetting rotating ring seats ensure the continuity of the leg-clamping training cycle, reducing the burden of body adjustment during training. Simultaneously, the torsion spring reset function makes the training movements smoother, effectively improving the standardization and efficiency of mid-to-late stage training, and meeting the advanced training needs after muscle strength gradually recovers.

[0023] 3. By adding and setting a dynamic adjustment mechanism, this invention allows users to perform postpartum pelvic floor muscle rehabilitation training. First, the mechanism collects pressure data in real time during the training process through a pressure sensor. Then, in conjunction with a PID controller, it achieves precise control of the current intensity of the electromagnetic coil seat, thereby changing the amount of magnetic particles attached in the magnetic suspension and dynamically adjusting the resistance when the rotating ring seat rotates. Secondly, this dynamic adjustment mode can automatically adapt the training resistance according to the different muscle strength levels and rehabilitation stages of postpartum women. For those with weak muscle strength, the resistance is reduced to avoid muscle damage, while for those with better muscle strength recovery, the resistance is increased to ensure training intensity. This completely solves the problem of traditional equipment's fixed resistance not being able to be personalized, and significantly improves the safety and targeting of rehabilitation training.

[0024] 4. By adding and setting up a multi-dimensional synergistic mechanism, this invention enables users to perform postpartum pelvic floor muscle rehabilitation training. This mechanism not only achieves precise coverage of different areas of the pelvic floor muscles and related sphincter muscles through flexible electrode seats, but also allows the pulse generator to output personalized low-frequency pulses by combining the baseline data of electromyography (EMG) collected by the EMG sensor. This achieves precise awakening of weak areas of the pelvic floor muscles. Furthermore, through a two-stage training mode that combines passive electrical stimulation awakening with active contraction, it not only helps those with severely low muscle strength to start the rehabilitation process, but also gradually cultivates active contraction ability, avoiding over-reliance on passive stimulation. At the same time, the overcurrent and overvoltage protector monitors the electrical stimulation parameters in real time, and immediately cuts off the output in case of abnormality to ensure training safety. It can also improve the persistence and effectiveness of rehabilitation training by dynamically adjusting the electrical stimulation parameters. Attached Figure Description

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see the appendix Figure 1 -Appendix Figure 2 This invention provides a pressure-sensing-based postpartum pelvic floor muscle rehabilitation training device, including a training bed 1. The bottom of the training bed 1 is fixedly connected to a support seat 16 for supporting and fixing it, and a positioning pillow 2 for positioning the user's head is provided on one side of the top of the training bed 1.

[0036] Please see the appendix Figure 3 and attached Figure 5 A rhythm assist mechanism, which is located at the bottom of the training bed 1, is used to assist the user in adjusting the training rhythm during the initial rehabilitation training.

[0037] The rhythm assist mechanism includes a mounting frame 6. The mounting frame 6 is fixedly connected to the top of the training bed 1 on the side away from the positioning pillow 2. The mounting frame 6 is fixedly connected to the end of the mounting frame 6 away from the training bed 1. A timing display screen 4 for reminding the user of the breathing training rhythm is set in the middle of the bottom of the mounting frame 5. A sliding seat 7 is slidably connected to the mounting frame 6. Tension rings 9 are set on both sides of the bottom of the sliding seat 7. A fixed seat 8 is fixedly connected to the middle side of the mounting frame 6. The fixed seat 8 and the sliding seat 7 are connected by multiple elastic bands 19.

[0038] When the rhythm assist mechanism is activated, during the initial stage of rehabilitation training, the user often controls the contraction and relaxation of the muscles around the pelvic floor muscles by coordinating their breathing. At this time, the user lies flat on the training bed 1, and after lying flat, the positioning pillow 2 positions the user's body on the training bed 1. Then, the user uses the timing display screen 4 on the mounting base 5 to time or remind the user, thereby coordinating their own breathing with the counting or prompts of the timing display screen 4 to control the contraction and relaxation of the muscles around the pelvic floor muscles during rehabilitation training.

[0039] During the rehabilitation training phase involving coordinated breathing, as a further exercise, the user can hold the stretching ring 9 and simultaneously pull it during breathing exercises. As the stretching ring 9 moves, it causes the sliding seat 7 on the mounting frame 6 to move synchronously. During this movement, the elastic band 19 between the sliding seat 7 and the fixed seat 8 is stretched and opened. After being stretched to a certain extent, the elastic band 19 then causes the sliding seat 7 on the mounting frame 6 and the stretching ring 9 at its bottom to return to their original position. By coordinating the stretching device with breathing, the user can engage the upper body muscles and gluteal muscles, thereby enhancing the training effect on the pelvic floor muscles.

[0040] The rhythm assist mechanism also includes rubber elastic balls 15. Rubber elastic balls 15 are provided on both sides of the bottom of the training bed 1. Hand grip ball seats 22 are provided on both sides of the middle of the top of the training bed 1. The rubber elastic balls 15 on the same side are connected to the inside of the hand grip ball seats 22 through rubber connecting tubes 18. Multiple mounting ring seats 23 are equidistantly arranged inside the rubber connecting tubes 18. One-way seats 24 are rotatably connected to one side of each mounting ring seat 23. Multiple return flow microholes 25 are arranged in a circular array on each one-way seat 24. A counterweight seat is provided on each rubber connecting tube 18.

[0041] After the above training reaches a certain intensity, the user begins the final training phase of the initial training stage. The user lies flat on the training bed 1 again, closes their eyes, and holds the ball seat 22 tightly with both hands. This allows the air inside the ball seat 22 to enter the rubber elastic ball 15 through the rubber connecting tube 18. At the same time, the user begins to inhale. As the air in the rubber connecting tube 18 flows from the ball seat 22 into the rubber elastic ball 15, the air compresses the one-way seat 24 on the mounting ring seat 23, causing the one-way seat 24 on the mounting ring seat 23 to fully open, thus allowing the air inside the ball seat 22 to smoothly enter the rubber elastic ball 15.

[0042] When the hand-held ball seat 22 becomes flat, the user releases their grip on the ball seat 22 and exhales simultaneously. At this time, due to the gas pressure inside the rubber elastic ball 15, the gas inside the rubber elastic ball 15 slowly flows back to the hand-held ball seat 22 through the reflux micro-hole 25 on the one-way seat 24, causing the hand-held ball seat 22 to return to its original shape, thus completing one training cycle. By repeating the above operation, the breathing-assisted training of the early stage of pelvic floor muscle can be completed.

[0043] Please see the appendix Figure 4 Advanced training facility, set up on training bed 1, is used to provide users with intermediate and later pelvic floor muscle rehabilitation training.

[0044] The advanced training mechanism includes an angle adjustment seat 3. An angle adjustment seat 3 is rotatably connected to the middle side of the top of the training bed 1. An installation column 13 is provided on the top side of the angle adjustment seat 3. Multiple rotating ring seats 26 that are automatically reset by torsion springs are rotatably connected at equal intervals on the outer wall of the installation column 13. Two fitting seats 10 are mirror images provided on the top two sides of the angle adjustment seat 3. Each fitting seat 10 has a fitting groove 20 on its outer wall for fitting the inner thigh. One side of the fitting seat 10 is connected to the outer wall of the corresponding rotating ring seat 26.

[0045] When the advanced training facility is activated, once the user has completed the initial rehabilitation training or their physical condition is suitable for the intermediate and later stages of training, the user first adjusts the angle adjustment seat 3 on the training bed 1 to a suitable angle for their posture. Then, the user adjusts their body position so that the inner thigh of the user fits into the fitting groove 20 on the fitting seat 10. Afterward, the user clamps their thighs together, causing the fitting seat 10 on the mounting column 13 to move inward synchronously. As the fitting seat 10 moves, it simultaneously causes the rotating ring seat 26 on the mounting column 13 to rotate synchronously. When it moves to the designated angle, the torsion spring on the rotating ring seat 26 will cause it and the fitting seat 10 to return to their original positions, thus completing one training cycle.

[0046] When the user's thigh moves the fitting seat 10, the fitting seat 10 will also simultaneously cause the adductor muscles of the thigh to contract. The adductor muscles and pelvic floor muscles have a synergistic effect in the body structure. When the legs are clamped, the active contraction of the pelvic floor muscles will be directly triggered, simulating the core contraction-relaxation movement of Kegel exercises, thereby achieving advanced training for the user.

[0047] Please see the appendix Figure 6 -Appendix Figure 7 A dynamic adjustment mechanism, which is installed on the training bed 1, is used to dynamically adjust the resistance during the user's pelvic floor muscle rehabilitation training.

[0048] The dynamic adjustment mechanism includes a concave cavity 30. The concave cavity 30 is provided in the middle of the inner side of the rotating ring seat 26. Multiple partition plates 31 are arranged in a circular array on the inner wall of the concave cavity 30. The multiple partition plates 31 divide the interior of the concave cavity 30 into multiple magnetic suspension fluid cavities 33 with equal volume at equal intervals, and the interior of each magnetic suspension fluid cavity 33 is filled with magnetic suspension fluid.

[0049] When the dynamic adjustment mechanism is activated, the pressure sensor 28 on the fitting seat 10 monitors the pressure data information of the user when the user is performing pelvic floor muscle rehabilitation training through the advanced training mechanism, and transmits the data information to the PID controller 17. When the pressure data information transmitted from the pressure sensor 28 exceeds the set threshold, it indicates that the user's physical condition or rehabilitation level does not meet the current training requirements.

[0050] The dynamic adjustment mechanism also includes sealing gaskets 29. Sealing gaskets 29 are provided in the middle of the upper and lower sides of the rotating ring seat 26. Pressure sensors 28 are provided in the middle of the fitting groove 20. An electromagnetic coil seat 32 is provided at the bottom of the outer wall of the mounting column 13. A PID controller 17 is provided on the front side of the training bed 1 near the positioning pillow 2.

[0051] At this time, the PID controller 17 reduces the current intensity of the electromagnetic coil seat 32 on the mounting column 13, thereby reducing the number of magnetic particles in the magnetic suspension fluid in the concave cavity 30 and magnetic suspension fluid cavity 33 adhering to the corresponding positions on the outer wall of the mounting column 13. As a result, when the fitting seat 10 drives the rotating ring seat 26 on the mounting column 13 to rotate, the friction force of the concave cavity 30 and magnetic suspension fluid cavity 33 corresponding to the outer wall of the mounting column 13 is reduced. Conversely, the PID controller 17 controls and increases the current intensity of the electromagnetic coil seat 32, thereby increasing the number of magnetic particles in the magnetic suspension fluid in the concave cavity 30 and magnetic suspension fluid cavity 33 adhering to the corresponding positions on the outer wall of the mounting column 13. This increases the resistance of the rotating ring seat 26 and the fitting seat 10 during rotation, thus completing the dynamic adjustment of the resistance of the user during rehabilitation training.

[0052] Please see the appendix Figure 8 The multidimensional synergistic mechanism, set on training bed 1, is used to perform multidimensional synergistic training of the muscles around the pelvic floor muscles for the user.

[0053] The multidimensional collaborative mechanism includes a matching seat 11. The matching seat 11 is located on one side of the middle part of the top of the training bed 1. Multiple positioning seats 34 are equidistantly arranged on the top side of the matching seat 11 near the positioning pillow 2. Multiple flexible electrode seats 21 are provided on the top of both the positioning seats 34 and the matching seat 11. The multiple flexible electrode seats 21 correspond to the anterior, middle and posterior regions of the user's pelvic floor muscles and the related muscle groups of the urethral sphincter and anal sphincter, respectively. Electromyography sensors 27 are provided on both sides of the middle part of the fitting groove 20.

[0054] When the multidimensional collaborative mechanism is activated, after the user completes the above training each time, the user lies flat on the training bed 1 and begins the final collaborative training. First, the user's waist, buttocks and corresponding pelvic floor muscles are matched with the flexible electrode seat 21 and positioning seat 34 on the matching seat 11. At this time, the PID controller 17 collects the electromyographic baseline data of the user in the resting state through the electromyographic sensor 27.

[0055] The next phase of collaborative training is divided into two stages: passive electrical stimulation arousal and active contraction coordination. In the passive stage, the PID controller 17 outputs low-frequency pulses to the flexible electrode seat 21 on the matching seat 11 through the pulse generator 14 based on the electromyographic baseline data transmitted from the electromyographic sensor 27, thereby stimulating the user's pelvic floor muscle fibers to contract passively and awaken the damaged nerves and muscles.

[0056] During the user's training process, the PID controller 17 continuously compares the electromyographic signal with the preset standard value. If the electromyographic signal in a certain area is weak, it automatically increases the electrical stimulation intensity of the electrode channel in that area. If muscle spasm is detected, it pauses the electrical stimulation in that area or controls the pulse generator 14 to output low-frequency, low-amplitude pulses during the training process.

[0057] The multidimensional collaborative mechanism also includes a pulse generator 14. A pulse generator 14 is provided on one side of the bottom middle of the training bed 1, and an overcurrent and overvoltage protector 12 is provided on the other side of the bottom middle of the training bed 1.

[0058] When in the active phase, the PID controller 17 controls the timing display screen 4 on the mounting base 5 to issue an active contraction command. The user voluntarily contracts the pelvic floor muscles, and the electromyography sensor 27 collects the electromyographic signals during the contraction process in real time. The PID controller 17 analyzes the amplitude and frequency characteristics of the electromyographic signals to determine the effectiveness of the contraction. At the same time, it dynamically adjusts the output parameters of the pulse generator 14 to avoid over-reliance on passive stimulation. The overcurrent and overvoltage protector 12 monitors the electrical stimulation current and voltage in real time. Once an abnormality occurs, the output is immediately cut off to ensure training safety, thereby achieving a multi-dimensional synergistic training effect for the user.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
