Description

Technical Field

[0001] This invention belongs to the field of medical rehabilitation technology, specifically a device for repairing rectus abdominis diastasis and pelvic floor rehabilitation. Background Technology

[0002] Diastasis recti and pelvic floor dysfunction are common problems in postpartum women and some women who have undergone abdominal surgery or have long-term increased abdominal pressure. Diastasis recti refers to excessive stretching of the linea alba on both sides of the rectus abdominis muscle, leading to abdominal wall laxity and bulging, which not only affects appearance but also weakens the support of the abdominal core muscles for the spine and internal organs. Pelvic floor dysfunction manifests as pelvic floor muscle laxity and decreased contractility, leading to a series of problems such as urinary incontinence, uterine prolapse, and sexual dysfunction.

[0003] Currently, most diastasis recti repair devices on the market focus on abdominal training, such as various abdominal muscle trainers and abdominal massagers. These devices primarily train the contraction and stretching of the rectus abdominis muscle, promoting its recovery by simulating abdominal movements or stimulating the abdominal muscles.

[0004] Existing pelvic floor rehabilitation devices mainly focus on individual training of the pelvic floor muscles, such as pelvic floor muscle electrical stimulators and biofeedback devices. These devices help patients perceive and control the contraction of the pelvic floor muscles through electrical stimulation or biofeedback technology, thereby enhancing the strength and endurance of the pelvic floor muscles.

[0005] Patients often need to use different devices for abdominal and pelvic floor training during rehabilitation, which not only increases rehabilitation time and cost but may also lead to poor rehabilitation results. For example, a patient may need to use an abdominal muscle trainer to repair the rectus abdominis muscle first, and then use a pelvic floor muscle electrical stimulator to train the pelvic floor muscles. This separate training method cannot achieve synchronous recovery of the rectus abdominis and pelvic floor muscles, resulting in a prolonged rehabilitation period and difficulty in achieving the expected rehabilitation results.

[0006] Given the shortcomings of existing technologies, there is an urgent need for a device that can simultaneously repair diastasis recti and pelvic floor muscle dysfunction and achieve synergistic training of both. Summary of the Invention

[0007] To address the aforementioned problems, the present invention aims to provide a device for the repair of rectus abdominis diastasis and pelvic floor rehabilitation, which can help patients restore the function of the rectus abdominis and pelvic floor muscles in a single training session, thereby shortening the rehabilitation cycle, improving rehabilitation effectiveness, and ultimately achieving a more comprehensive and efficient rehabilitation goal.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows:

[0009] A device for repairing rectus abdominis diastasis and for pelvic floor rehabilitation includes a rectus abdominis repair component and a pelvic floor muscle repair component; the rectus abdominis repair component is used to perform electrical stimulation therapy on the rectus abdominis muscle of a patient.

[0010] The pelvic floor muscle repair component includes at least one insert, on which an in vivo electrode and a pelvic floor muscle contraction sensing component are disposed. The pelvic floor muscle contraction sensing component is used to adjust the electrical stimulation intensity of the rectus abdominis muscle based on the patient's pelvic floor muscle contraction intensity. The pelvic floor muscle contraction intensity is positively correlated with the electrical stimulation intensity of the rectus abdominis muscle.

[0011] A connecting component is provided between the rectus abdominis muscle repair component and the pelvic floor muscle repair component. The connecting component is used to connect the circuit of the pelvic floor muscle contraction sensing component and the rectus abdominis muscle repair component when the patient performs synergistic repair training of the rectus abdominis muscle and the pelvic floor muscle.

[0012] Working principle:

[0013] The core of this invention lies in achieving simultaneous repair of the rectus abdominis muscle and pelvic floor muscles through the synergistic work of the rectus abdominis repair component and the pelvic floor muscle repair component. The specific principle is as follows:

[0014] Rectus abdominis repair component: It acts directly on the rectus abdominis muscle through electrical stimulation to help it restore strength and function.

[0015] Pelvic floor muscle repair component: The insert (such as a probe inside the vagina or rectum) contains an internal electrode and a pelvic floor muscle contraction sensing component. The pelvic floor muscle contraction sensing component can monitor the contraction intensity of the patient's pelvic floor muscles in real time and transmit the signal to the rectus abdominis muscle repair component.

[0016] Connection component: When the patient performs synergistic training of the rectus abdominis and pelvic floor muscles, the connection component connects the circuit of the pelvic floor muscle contraction sensing component with the rectus abdominis repair component to achieve dynamic linkage between the two.

[0017] Dynamic adjustment mechanism: The pelvic floor muscle contraction sensing component dynamically adjusts the electrical stimulation intensity of the rectus abdominis muscle according to the contraction intensity of the pelvic floor muscles, ensuring that the training intensity of the rectus abdominis muscle matches the tolerance of the pelvic floor muscles.

[0018] The above approach has the following beneficial effects:

[0019] 1. Traditional methods for repairing the rectus abdominis and pelvic floor muscles are usually performed separately. However, this approach achieves synergistic repair of both muscles through pelvic floor muscle contraction sensing components and connecting components. This design not only shortens the rehabilitation period but also improves rehabilitation outcomes.

[0020] 2. This solution uses a pelvic floor muscle contraction sensing component to monitor the contraction intensity of the pelvic floor muscles in real time and dynamically adjust the electrical stimulation intensity of the rectus abdominis muscle. This avoids the risk of secondary damage to the pelvic floor muscles due to excessive rectus abdominis muscle training intensity, thereby improving the safety and effectiveness of rehabilitation.

[0021] 3. This solution integrates rectus abdominis muscle repair and pelvic floor muscle repair into one device, eliminating the need for patients to switch between different devices, simplifying the operation process and improving the convenience of rehabilitation.

[0022] Furthermore, the rectus abdominis repair component includes a pant body; a tension band is provided on the pant body, a waistband is provided at the other end of the tension band, an abdominal pad is provided on the inside of the waistband, and several electrode patches are symmetrically arranged on the abdominal pad, with the electrode patches electrically connected to the main circuit.

[0023] Beneficial effects: The combination of tension band and waist belt provides physical support, helping patients maintain abdominal stability during training and reducing abdominal sagging or laxity caused by diastasis recti.

[0024] The electrode patches act directly on the rectus abdominis muscle, promoting muscle contraction and recovery through electrical stimulation. Combined with physical support, this achieves a more comprehensive repair effect.

[0025] Furthermore, the pants body has at least one opening; the connecting component includes a connecting ring, which is embedded in the opening; the connecting ring has a groove, which is connected to a through slot; an annular carrier is slidably fitted inside the groove, and several second springs are provided between the annular carrier and the bottom of the groove; spring contacts are provided in the side wall of the groove, and the spring contacts are connected to the main circuit of the electrode patch; a circuit post is provided on the side of the annular carrier near the spring contacts, and the circuit post is electrically connected to a local circuit, which is located inside the annular carrier; when the spring contacts align with the circuit post, the main circuit of the electrode patch forms a closed circuit.

[0026] Beneficial effects: When the electrode patch is operating normally, the annular carrier, supported by the second spring, precisely aligns the circuit terminal with the spring contact. The electrode patch (main circuit), spring contact, circuit terminal, and local circuit form a complete closed circuit. When the annular carrier is compressed by external force, the circuit terminal and spring contact misalign until they completely separate. At this point, the spring contact can be connected to an external circuit. This design provides greater flexibility to the device, allowing other circuits to be connected when needed.

[0027] Furthermore, the pelvic floor muscle contraction sensing component includes several first piston grooves circumferentially opened on the outside of the insert. Each first piston groove has a pressure block slidably fitted inside it. A multi-port tube is connected between the first piston grooves. The outlet end of the multi-port tube is connected to an elastic airbag. A Tesla valve channel is connected along the communication path between the multi-port tube and the elastic airbag. The fluid in the Tesla valve channel flows in the opposite direction from the multi-port tube to the elastic airbag. A second piston groove is connected at the point where the resistance is greatest in the Tesla valve channel. A piston post is slidably fitted inside the second piston groove. A first spring is provided at the bottom of the piston post to support the piston post's reset. A sliding rheostat is provided on one side of the piston post. The slider of the sliding rheostat is fixedly connected to one side of the piston post. The sliding rheostat is electrically connected to an electrode.

[0028] The insert has a base and a locking mechanism at its tail end. When the base is inserted into the connecting ring, the base slides into the groove. A sliding groove is provided on the outside of the base, and the electrode is located in the sliding groove. When the electrode is connected to the spring contact, the sliding rheostat is connected in series to the main circuit of the electrode patch. The locking mechanism is used to fix the base in the groove.

[0029] Beneficial effects: When synergistic training of the rectus abdominis and pelvic floor muscles is required, the insert is inserted into the patient's vagina or rectum along the opening. During insertion, the base slides into the bottom of the groove along the side wall of the connecting ring until the electrode plate and the spring contact are connected. The sliding rheostat is connected in series to the main circuit of the electrode patch to realize the dynamic adjustment of the pelvic floor muscle contraction intensity and the rectus abdominis electrical stimulation intensity. Then the base is fixed by the locking mechanism.

[0030] When the patient's pelvic floor muscles contract, the pressure block slides within the first piston groove, transmitting pressure to the elastic airbag through the multi-port tube, causing the airbag to inflate. The greater the contraction strength of the patient's pelvic floor muscles (e.g., the contraction force generated per unit time), the greater the resistance generated by the Tesla valve channel. This resistance acts on the piston rod through the second piston groove, causing the piston rod to compress the first spring and move, changing the resistance value of the sliding rheostat, thereby adjusting the intensity of electrical stimulation.

[0031] The pelvic floor muscle contraction sensing component is designed to achieve real-time correlation between the intensity of pelvic floor muscle contraction and the intensity of electrical stimulation of the rectus abdominis muscle through pressure transmission and dynamic adjustment mechanisms. This design not only improves the flexibility and adaptability of the device but also significantly enhances the safety and effectiveness of rehabilitation training.

[0032] Furthermore, the locking mechanism includes at least one locking element; the locking element is circumferentially fixed to the outside of the base, and a torsion member is provided at the bottom of the base, which is used to facilitate the user to rotate the base; a slot is opened on the surface of the connecting ring, the slot corresponds to the locking element, and one end of the slot is connected to a limiting groove. When the base enters the groove, the locking element slides and engages with the slot and the limiting groove in sequence.

[0033] Beneficial effects: When the base needs to be fixed, align the locking piece with the slot. After the locking piece enters the slot, rotate the toggle switch to screw the locking piece into the limiting groove. When the base needs to be removed, rotate the toggle switch in the opposite direction to allow the locking piece to slide out of the limiting groove and move out along the slot.

[0034] The design of the card slot and the limiting slot ensures that the insert will not slip out during training and affect normal training.

[0035] Furthermore, it also includes an electromyography (EMG) acquisition module and a control module. The EMG acquisition module is used to acquire the patient's EMG signals during the training process; the control module is used to determine the patient's rehabilitation progress based on the EMG signals and adjust the electrical stimulation parameters of the pelvic floor muscles and / or rectus abdominis muscles.

[0036] Beneficial effects: Through real-time acquisition and analysis of electromyographic signals, the device can accurately assess the patient's rehabilitation progress and avoid overtraining or undertraining.

[0037] Furthermore, it also includes an interaction module, which provides training guidance and abnormal warnings based on electromyographic signals.

[0038] Beneficial effects: Real-time training guidance ensures patients maintain proper form during training, improving effectiveness. Personalized training suggestions are provided based on the patient's rehabilitation progress and current condition, helping them gradually increase training intensity and complexity, ensuring the scientific rigor and effectiveness of the rehabilitation process. Patients can understand their training status and rehabilitation progress through real-time feedback from the interactive module, enhancing their sense of participation and confidence.

[0039] Furthermore, the surface of the pressure block is covered with an elastic membrane.

[0040] Beneficial effects: The cushioning and protective function of the elastic membrane effectively prevents the pressure block from pinching and injuring the patient's internal tissues during activity, ensuring the safety of the training process.

[0041] Furthermore, an ultrasonic sensor is installed on the abdominal pad. The ultrasonic sensor is used to collect information on the movement of the patient's organs and abdominal wall. The control module is also used to determine whether the abdominal pressure in the patient is stable based on the movement of the organs and abdominal wall, and to control the operation of the electrode patch.

[0042] Beneficial effects: Real-time intra-abdominal pressure monitoring effectively prevents common complications during electrical stimulation training, such as organ prolapse and abdominal wall hernia; combined with dual data of organ activity and abdominal wall deformation, the timing of electrical stimulation is dynamically optimized.

[0043] Furthermore, the insert surface is coated with a hydrogel coating.

[0044] Beneficial effects: The lubricating and softening properties of the hydrogel coating significantly improve patient comfort and reduce discomfort during use. The hydrogel coating has good biocompatibility and will not cause immune or allergic reactions in patients, ensuring safe use. Attached Figure Description

[0057] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0059] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0060] The following detailed description illustrates the specific implementation method:

[0061] Example 1 is basically as shown in the appendix. Figures 1-11The following is an illustration of a device for repairing rectus abdominis diastasis and for pelvic floor rehabilitation, mainly comprising a rectus abdominis repair component and a pelvic floor muscle repair component. The rectus abdominis repair component is used for electrical stimulation therapy of the patient's rectus abdominis muscles. Specifically, the rectus abdominis repair component includes a pant body 2, which in this embodiment is a close-fitting pair of underwear that the patient can wear. The pant body 2 has at least one opening; in this embodiment, the front opening 5 and the rear opening 6 are respectively located on the front and back sides of the pant body 2, corresponding to the patient's vagina and rectum, respectively. A tension band 4 is provided on the front side of the pant body 2. Figure 2 A waist belt 3 is provided at the top of the tension band 4, and an abdominal padding layer 301 is provided on the inner side of the waist belt 3. In this embodiment, the tension band 4, waist belt 3, and abdominal padding layer 301 are all integrated into one piece. (See attached diagram.) Figure 4 As shown, several electrode patches 302 are symmetrically arranged on the abdominal padding 301. The electrode patches 302 are electrically connected to the main circuit. In this embodiment, the main circuit is arranged inside the tension band 4 and the trouser body 2.

[0062] Combined with appendix Figure 5 Appendix Figure 6 and attached Figure 7 As shown, the pelvic floor muscle repair component includes at least one insert 7. In this embodiment, the surface of the insert 7 is coated with a hydrogel coating. An internal electrode 707 and a pelvic floor muscle contraction sensing component are disposed within the insert 7. In this embodiment, the internal electrode 707 is specifically a vaginal electrode or a rectal electrode. The pelvic floor muscle contraction sensing component is used to adjust the electrical stimulation intensity of the rectus abdominis muscle based on the strength of the patient's pelvic floor muscle contraction. The strength of the pelvic floor muscle contraction is positively correlated with the electrical stimulation intensity of the rectus abdominis muscle; that is, the higher the strength of the pelvic floor muscle contraction (indicating stronger pelvic floor muscle strength), the higher the electrical stimulation intensity of the rectus abdominis muscle (rectus abdominis muscle training increases abdominal pressure, thus requiring higher strength of the pelvic floor muscles).

[0063] Specifically, the pelvic floor muscle contraction sensing component includes several first piston grooves 709 circumferentially opened on the outer side of the insert 7, and each first piston groove 709 has a pressure block 708 slidably fitted within it. Preferably, Figure 7 The outermost surface of the pressure-bearing block 708 is curved, and the surface of the pressure-bearing block 708 is covered with an elastic membrane 705. The elastic membrane 705 encloses all the pressure-bearing blocks 708 within the first piston groove 709. A multi-port pipe 710 connects the first piston grooves 709. The multi-port pipe 710 has multiple inlets and one outlet, the number of inlets corresponding to the number of first piston grooves 709. The outlet end of the multi-port pipe 710 is connected to an elastic airbag 712. A Tesla valve channel 711 connects the multi-port pipe 710 and the elastic airbag 712. (The last sentence appears to be incomplete and possibly refers to a different topic.) Figure 7 and attached Figure 10As shown, the fluid (air in this embodiment) in the Tesla valve channel 711 flows in the opposite direction from the multi-port pipe 710 to the elastic airbag 712. A second piston groove 714 is connected to the point of greatest resistance within the Tesla valve channel 711 (i.e., the junction within the Tesla valve channel 711). Specifically, the Tesla valve channel 711 and the second piston groove 714 are connected via a transfer channel 713. A piston post 715 is slidably fitted within the second piston groove 714. A first spring 716 is provided at the bottom of the piston post 715, supporting the piston post 715 to return to its original position. The two ends of the first spring 716 are respectively bonded and fixed to the bottom of the piston post 715 and the bottom of the second piston groove 714. A sliding rheostat 717 is provided on one side of the piston column 715. Specifically, a side groove 718 is provided between the second piston groove 714 and the sliding rheostat 717. The slider of the sliding rheostat 717 passes through the side groove 718 and is welded and fixedly connected to one side of the piston column 715. The sliding rheostat 717 is electrically connected to an electrode 704. Specifically, the electrode 704 is made of metal foil or conductive material.

[0064] A connecting component is provided between the rectus abdominis muscle repair component and the pelvic floor muscle repair component. The connecting component is used to connect the circuit of the pelvic floor muscle contraction sensing component and the rectus abdominis muscle repair component when the patient performs synergistic repair training of the rectus abdominis muscle and the pelvic floor muscle.

[0065] Specifically, in conjunction with the appendix Figure 8 As shown, the connecting component includes a connecting ring 8, which is embedded in the opening. Specifically, in this embodiment, the connecting ring 8 is bonded and fixed inside the front opening 5, and the inner diameter of the connecting ring 8 is equal to the inner diameter of the opening; in conjunction with the attached... Figure 8 and attached Figure 11 As shown, a groove 803 is provided in the connecting ring 8, and the groove 803 is connected to a through groove 804. The inner diameter of the groove 803 is larger than that of the through groove 804. An annular carrier 805 is slidably fitted in the groove 803. Several second springs 806 are bonded and fixed between the annular carrier 805 and the bottom of the groove 803. Spring contacts (existing technology, commonly found in battery slots) are provided in the side wall of the groove 803. The spring contacts are connected to the main circuit of the electrode patch 302. A circuit post (a metal protrusion or plane) is provided on the side of the annular carrier 805 near the spring contacts. The circuit post is used to connect to the contacts of the external circuit or the battery slot to ensure current conduction. The circuit post is electrically connected to a local circuit. In this embodiment, the local circuit is an arc-shaped wire. The local circuit is located in the annular carrier 805. When the spring contacts are connected to the circuit post, the main circuit of the electrode patch 302 forms a closed circuit.

[0066] Preferably, the tail end of the insert 7 (the end of the insert 7 inserted into the patient's body is the head end, and the end outside the patient's body is the tail end) is provided with a base 701 and a locking mechanism. In this embodiment, the base 701 is disc-shaped, and the base 701 and the insert 7 are integrated. When the base 701 is inserted into the connecting ring 8, the base 701 slides in conjunction with the groove 803. A sliding groove 703 is provided on the outer side of the base 701, which is combined with the attached... Figure 5 Appendix Figure 6 and attached Figure 7 As shown, electrode 704 is located within slide groove 703. When electrode 704 engages with spring contact, sliding rheostat 717 is connected in series to the main circuit of electrode patch 302. A locking mechanism is used to fix base 701 within groove 803. Specifically, the locking mechanism includes at least one locking member 702; in this embodiment, two locking members 702 are provided. The locking member 702 is circumferentially fixed to the outside of base 701 by welding. A torsion member 706 is welded to the bottom of base 701, and the torsion member 706 facilitates user rotation of base 701. (See attached diagram.) Figure 8 As shown, the surface of the connecting ring 8 has a slot 801, which corresponds to the slot 702 (i.e., the same number and corresponding position). Figure 8 The bottom of the card slot 801 is connected to the limiting groove 802. When the base 701 enters the groove 803, the card 702 slides and engages with the card slot 801 and the limiting groove 802 in sequence.

[0067] The specific implementation process is as follows:

[0068] In this embodiment, electrical stimulation training of the rectus abdominis muscle and pelvic floor muscles can be performed separately.

[0069] When performing synergistic electrical stimulation training of the rectus abdominis and pelvic floor muscles:

[0070] Put the trousers 2 on the patient, adjust the tension band 4 and waistband 3 to ensure that the abdominal pad 301 fits snugly against the rectus abdominis muscle area, providing appropriate physical support. Select either the vaginal insert 7 or the rectal insert 7 according to the patient's needs, and gently push the tip of the insert 7 into the corresponding cavity until the base 701 is aligned with the connecting ring 8. Secure the base 701 using the locking mechanism. Rotate the torsion member 706 to slide it from the slot 801 into the limiting slot 802, completing the mechanical locking and ensuring that the insert 7 will not slip out of the patient's body during training. At this time, the electrode 704 in the sliding groove 703 of the base 701 engages with the spring contact of the groove 803 of the connecting ring 8, connecting the sliding rheostat 717 in series to the main circuit of the electrode patch 302.

[0071] When the patient actively or passively (through electrical stimulation by the internal electrode 707) contracts the pelvic floor muscles, the pressure block 708 is squeezed and slides into the first piston groove 709, pushing the fluid (air) in the multi-pass tube 710 to flow to the elastic airbag 712.

[0072] Tesla valve channel 711 generates nonlinear resistance to the fluid flowing in the opposite direction. The resistance peak is transmitted to the second piston groove 714 through transfer channel 713, which pushes piston column 715 to compress first spring 716 and drive sliding rheostat 717 slider to move.

[0073] The resistance of the 717 sliding rheostat changes with the intensity of pelvic floor muscle contraction:

[0074] Increased contraction → increased displacement of piston column 715 → decreased resistance → increased current in the main circuit → increased intensity of electrical stimulation of the rectus abdominis muscle.

[0075] Contraction weakens → first spring 716 resets → resistance increases → current decreases → electrical stimulation intensity decreases.

[0076] After training, rotate the torsion member 706 in the opposite direction to make the locking member 702 slide out of the limiting groove 802, move it out of the base 701 along the locking groove 801, and gently remove the insert 7.

[0077] Example 2

[0078] The only difference from Embodiment 1 above is that it also includes an electromyography (EMG) acquisition module and a control module. The EMG acquisition module is used to acquire the patient's EMG signals during the training process. Specifically, the EMG acquisition module integrates several EMG sensors, which are distributed in the abdominal pad 301 and the trouser body 2, and are used to acquire the EMG signals of the pelvic floor muscles and rectus abdominis muscles. The control module is used to determine the patient's rehabilitation progress based on the EMG signals and to adjust the electrical stimulation parameters of the pelvic floor muscles and / or rectus abdominis muscles.

[0079] Preferably, it also includes an interaction module 1. In this embodiment, the interaction module 1 is a tablet computer (in some other embodiments, it can be a smartwatch, mobile APP, etc.). The interaction module 1 is used to provide training guidance (muscle training movements) and provide abnormal warnings based on electromyographic signals.

[0080] Preferably, an ultrasonic sensor (ultrasonic patch) is also provided on the abdominal pad 301. The ultrasonic sensor is used to collect the activity of the organs and the abdominal wall in the patient's body. The control module is also used to determine whether the abdominal pressure in the patient's body is stable based on the activity of the organs and the abdominal wall, and to control the operation of the electrode patch 302.

[0081] The specific implementation process is as follows: During the patient's synergistic training of the rectus abdominis and pelvic floor muscles, the electromyography (EMG) acquisition module collects the EMG signals of the patient's rectus abdominis and pelvic floor muscles in real time. Ultrasonic sensors collect real-time data on the activity of the patient's internal organs and abdominal wall.

[0082] Interactive module 1 provides real-time training guidance through voice or graphical interface to help patients correctly perform rehabilitation training movements.

[0083] The control module dynamically adjusts the intensity, frequency, and duration of electrical stimulation based on electromyographic signals and abdominal pressure stability to ensure that the training intensity matches the patient's tolerance.

[0084] When abnormal signals are detected (such as excessive muscle fatigue, abnormal contraction of pelvic floor muscles, unstable abdominal pressure, etc.), the interactive module 1 will issue an early warning in a timely manner to remind the patient to adjust the training intensity or suspend training.

[0085] Electromyographic signals: The electromyographic amplitude (μV) and contraction frequency (Hz) of the rectus abdominis and pelvic floor muscles were acquired simultaneously.

[0086] The ultrasound sensor uses a dual-frequency scanning mode (high frequency 5MHz scans abdominal wall movement, low frequency 2.5MHz monitors deep organ displacement); it acquires the abdominal wall deformation rate (reflecting abdominal wall relaxation) and organ movement trajectory (such as the vertical displacement of the bladder and uterus, indirectly calculating the abdominal pressure value) in real time.

[0087] Signal fusion and feature extraction:

[0088] Low-frequency interference signals such as breathing and heartbeat are filtered out using wavelet transform algorithm;
