Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a postoperative shaping garment for abdominal wall surgery. Specifically, it relates to a wearable shaping garment for rehabilitation after abdominal plastic surgery, and especially to a postoperative shaping garment that integrates pressure regulation, physiological monitoring, local decompression and hygiene care. Background Technology

[0002] Abdominal wall laxity is a pathological condition caused by factors such as pregnancy, rapid weight loss, or aging, resulting in impaired structural integrity of the abdominal skin, muscles, and fascia. Clinically, it manifests as loose abdominal skin, fat accumulation, and diastasis recti. Abdominal wall reshaping surgery is currently the preferred treatment for correcting this condition. It achieves abdominal rejuvenation by removing excess skin, absorbing accumulated fat, and repairing the rectus abdominis muscles.

[0003] However, postoperative rehabilitation management after abdominoplasty is a crucial factor affecting the surgical outcome. Existing clinical consensus (such as the "Expert Consensus on the Clinical Diagnosis and Treatment of Abdominal Wall Laxity 2025") clearly states that postoperatively, the abdomen should be appropriately compressed with elastic bandages or compression garments to reduce incision tension, prevent seroma, and promote flap adhesion and tissue healing. Simultaneously, close monitoring of intra-abdominal pressure, vital signs, and incision condition is essential postoperatively to prevent serious complications such as abdominal compartment syndrome.

[0004] Currently, postoperative compression garments on the market generally have the following technical defects: Insufficient pressure regulation capability: Traditional shapewear uses elastic fabric to passively apply pressure, which cannot adjust the pressure in a refined and zoned manner according to different postoperative stages (such as the acute edema period and the tissue healing period); Limited functionality: It only has the function of physical pressurization and cannot monitor key physiological indicators such as body temperature, heart rate, and bowel sounds in real time, making it difficult to meet the needs of early warning of postoperative complications. Lack of local care: Due to surgical incisions, drainage tubes or seepage in the lower abdomen and perineal area, frequent dressing changes are often required. The existing one-piece structure of shapewear is inconvenient to put on and take off, and is prone to causing secondary damage. Uneven pressure distribution: The existing design does not include zoned pressure design for key abdominal anatomical structures (such as the rectus abdominis, semilunar line, and umbilicus), which can easily lead to flap blood supply disorders or scar hyperplasia.

[0005] Furthermore, existing technologies suffer from the following deeper technical deficiencies: First, current compression garments primarily employ static compression, failing to dynamically adjust pressure based on changes in patient position (e.g., from lying down to standing) or activity level (e.g., rest versus walking). This results in excessive pressure affecting comfort during activity and insufficient pressure at rest, impacting treatment effectiveness. Second, current compression garments lack non-invasive methods for monitoring intra-abdominal pressure, a key early indicator of abdominal compartment syndrome. Traditional monitoring requires invasive measurement via indwelling bladder manometry, increasing the risk of complications for patients. The pain and infection risks of patients also limit the frequency and continuity of monitoring. Secondly, the current design of shapewear for local care is too simplistic, only considering perineal exposure without adequately addressing drainage tube fixation, exudate absorption, and ease of dressing changes. This necessitates significant movement of the shapewear during nursing procedures, increasing the risk of incision tearing. Finally, the material selection for current shapewear does not adequately consider the increased skin sensitivity of postoperative patients. Long-term wear can easily lead to skin complications such as contact dermatitis and folliculitis, affecting patient compliance and recovery outcomes. The combined existence of these technical deficiencies means that current postoperative rehabilitation management after abdominoplasty remains at an experience-based, fragmented, and inefficient stage, urgently requiring a postoperative rehabilitation device that enables intelligent, precise, and integrated management.

[0006] Therefore, developing a postoperative compression garment that can achieve zoned dynamic pressure application, integrate physiological monitoring, facilitate local care, and conform to ergonomics has significant clinical value and market prospects. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a postoperative compression garment for abdominal wall surgery, so as to solve the technical problems of inaccurate pressure adjustment, single function, inconvenient local care and unreasonable pressure distribution in the existing technology, and realize intelligent, precise and humanized rehabilitation management after abdominal wall plastic surgery.

[0008] The above-mentioned objective of this invention is achieved through the following technical solutions: This invention provides a postoperative compression garment for abdominal wall surgery, comprising: a vest body for wrapping the patient's torso; underwear connected to the lower part of the vest body for wrapping the patient's buttocks and perineum; an inflation component disposed on the vest body for providing zoned adjustable pressure to the abdomen; a monitoring component for collecting and displaying the patient's physiological parameters in real time; and a local care structure disposed on the underwear for exposing and caring for the lower abdomen and perineal area.

[0009] This invention, through the overall coordination of the above technical solutions, achieves the following synergistic effects: the one-piece molding design of the vest and underwear ensures the overall stability of the shapewear during wear, avoiding displacement and friction caused by traditional separate designs during patient movement; the synergistic effect of the inflation component and the monitoring component transforms pressure regulation from open-loop control to a closed-loop regulation system based on real-time physiological parameters—when the pressure sensor detects excessively high local pressure, the system can automatically or prompt the user to reduce the airbag pressure; when the bowel sound sensor detects weakened or absent bowel sounds, the system can prompt the user to check for the possibility of excessive pressure inhibiting intestinal peristalsis; the data fusion of the body temperature sensor and heart rate sensor can construct an early warning model for postoperative inflammatory responses, enabling timely warnings of complications such as infection and seroma. This multi-sensor fusion and actuator linkage technical solution has an overall effect far greater than the sum of the effects of using each functional module individually.

[0010] According to one embodiment of the present invention, the inflation assembly includes: at least two air bladders symmetrically arranged on the front piece of the vest body at a position corresponding to the lateral edge of the rectus abdominis muscle; an integrated inflation pump connected to each air bladder via an air tube; and a valve disposed on the air tube for independently controlling the inflation and deflation of each air bladder. The inflation assembly also includes a posture sensor for detecting changes in the patient's body position and automatically adjusting the target pressure value of the air bladder according to the changes in body position.

[0011] The air bladder has an M-shaped structure, the shape of which matches the surface projection area of ​​the lateral border of the rectus abdominis muscle and the semilunar line. In a preferred embodiment of the invention, the structural design of the M-shaped air bladder has unique anatomical considerations: the two lateral protrusions of the M-shape correspond to the lateral border of the rectus abdominis muscle, which is a key area that usually needs to be separated and fixed in abdominoplasty, and requires appropriate pressure after surgery to promote tissue adhesion; the central concave part of the M-shape corresponds to the linea alba region, which is not covered by a muscle layer and directly corresponds to the abdominal contents, and excessive pressure may lead to increased intra-abdominal pressure and discomfort; the medial protrusion of the M-shape corresponds to the semilunar line region, which is the junction of the rectus abdominis muscle and the external oblique muscle, and is also a sensitive area for postoperative skin flap blood supply, requiring precise pressure control to achieve a balance between compression hemostasis and protection of blood supply. Through extensive clinical anatomical studies, the inventors discovered that when using traditional circular or elliptical airbags for pressurization, the pressure is evenly distributed across the entire airbag coverage area. This makes it impossible to differentiate the pressure based on the anatomical characteristics and clinical needs of different areas, easily leading to a contradictory situation where the pressure is too high in the linea alba region and insufficient in the lateral border of the rectus abdominis muscle region. The invention's unique M-shaped airbag structure, through its distinctive concave-convex shape, achieves "selective pressurization" of different anatomical regions of the abdominal wall. Effective pressure is applied to areas requiring pressurization (lateral border of the rectus abdominis muscle, semilunar line), while natural decompression occurs in areas requiring protection (linea alba). This perfect match between shape and function is unattainable with traditional uniform airbags. Furthermore, the M-shaped airbag design also considers the placement requirements of postoperative drainage tubes. The concave portion of the M-shape naturally forms a "channel" through which the drainage tube can pass, avoiding the problem of poor drainage or ischemia and necrosis of the surrounding tissue caused by direct pressure from the airbag. This design concept, which unifies the consideration of anatomical structure, pressure distribution, and drainage management, reflects the profound thinking behind this invention's structural innovation.

[0012] According to one embodiment of the present invention, a first buckle is provided at the center of the front panel of the vest body for adjusting the lateral tightness of the vest body; two airbags are symmetrically arranged on both sides of the first buckle.

[0013] The first buckle is not only used to adjust the overall tightness of the vest, but more importantly, it serves as a symmetrical baseline for the two M-shaped air bladders, ensuring that the air bladders are precisely positioned anatomically at the lateral edge of the rectus abdominis muscle. When the patient adjusts the tightness using the first buckle, the lateral dimensions of the vest change, but the relative positions of the two air bladders with respect to the lateral edge of the rectus abdominis muscle remain unchanged. This is because the placement of the first buckle and the installation positions of the air bladders are carefully geometrically designed: the center line of the first buckle is aligned with the linea alba, and the symmetrical center lines of the two air bladders are aligned with the lateral edge of the rectus abdominis muscle. This alignment remains constant regardless of how the first buckle is adjusted. This design ensures that patients of different body types and waist circumferences can receive precise anatomically positioned compression, avoiding compression position deviations caused by body shape differences.

[0014] According to one embodiment of the present invention, the monitoring component includes: an electronic screen embedded in the upper front panel or the front side of the shoulder straps of the vest body; a sensor module including a body temperature sensor, a heart rate sensor, a pressure sensor, and a bowel sound sensor, respectively disposed at corresponding positions on the inner surface of the vest body that contacts the skin; the electronic screen is communicatively connected to the sensor module for displaying physiological parameters in real time; the electronic screen has a built-in microprocessor that runs a multimodal data fusion algorithm to generate complication risk warning information based on body temperature, heart rate, bowel sound, and pressure data.

[0015] In a preferred embodiment of the present invention, the location of the bowel sound sensor is specifically acoustically optimized. Bowel sounds are low-frequency sound signals generated by intestinal peristalsis, typically ranging from 100-500Hz. These signals are weak and easily interfered with by ambient noise and body movement. This invention places the bowel sound sensor on the inner side of the front panel of the vest, corresponding to the periumbilical region, and uses a flexible piezoelectric film as the sensing element. This allows for maximum contact with the abdominal skin, reducing sound signal attenuation in the air. Furthermore, the invention integrates an adaptive filtering algorithm that can identify and filter out respiratory sounds, heartbeat sounds, and ambient noise in real time, extracting a pure bowel sound signal. More importantly, this invention fuses bowel sound monitoring with pressure monitoring data. When the pressure sensor detects an increase in airbag pressure, the system automatically adjusts the gain and filtering parameters of the bowel sound sensor to compensate for changes in acoustic conduction characteristics caused by pressurization, thus obtaining reliable bowel sound signals under different pressure conditions. This pressure-acoustic combined monitoring technology enables the present invention to continuously and accurately monitor bowel sounds in environments with dynamic pressure changes. This is a technical effect that cannot be achieved by simply superimposing a pressure sensor and a bowel sound sensor.

[0016] According to one embodiment of the present invention, the front panel of the vest body is further provided with a pocket for accommodating the integrated air pump and power module.

[0017] According to one embodiment of the present invention, the underwear includes: a wearing part integrally formed with the vest body; a crotch part detachably connected to the lower edge of the wearing part, the crotch part having an elliptical hollow hole for exposing the perineum or a drainage tube outlet; the upper end of the crotch part is detachably fixed to the front side of the wearing part by a second buckle, and the lower end of the crotch part is detachably fixed to the rear side of the wearing part by a third buckle.

[0018] In a preferred embodiment of the invention, a replaceable absorbent pad is provided around the perforated opening of the crotch area. This absorbent pad is made of highly absorbent fiber material, capable of absorbing small amounts of exudate from the perineal incision or drainage tube outlet, keeping the local skin dry and reducing the risk of infection. The absorbent pad is detachably connected to the crotch area via magnetic or Velcro fasteners, allowing for easy replacement as needed based on exudate levels, without requiring the replacement of the entire crotch area. The main body of the crotch area features a double-layer structure: an outer layer of breathable elastic fabric and an inner layer of antibacterial, skin-friendly fabric. A sandwich layer is provided between the two layers to accommodate ice packs or heating pads, enabling cold or hot compresses to the perineum. This design, integrating nursing and therapeutic functions into the detachable crotch area, allows for multiple nursing procedures such as perineal cleaning, dressing changes, cold compresses, and hot compresses without removing the entire shapewear, greatly simplifying the nursing process, reducing the difficulty for nursing staff, and avoiding secondary damage to the patient's incision caused by repeated donning and doffing of the shapewear. The second and third fasteners are preferably magnetic or push-button fasteners, which are easy to operate with one hand. Even when the patient is in a supine or semi-recumbent position, nursing staff can easily remove and install the crotch support.

[0019] According to one embodiment of the present invention, the inflation pressure range of the airbag is 0-50 mmHg, and the valve is a miniature solenoid valve, which is wirelessly controlled by the electronic screen or an external control terminal.

[0020] In a preferred embodiment of the present invention, the miniature solenoid valve is a three-way proportional solenoid valve, which can not only control the inflation and deflation of the airbag but also achieve continuous proportional adjustment of the airbag pressure. Compared with traditional on / off solenoid valves, the three-way proportional solenoid valve can continuously adjust the valve opening according to the magnitude of the control signal, thereby achieving stepless adjustment of the airbag pressure and making pressure control more precise and smooth. The present invention also sets up a pressure closed-loop control algorithm. The microprocessor built into the electronic screen dynamically adjusts the opening of the miniature solenoid valve according to the deviation between the real-time pressure value fed back by the pressure sensor and the target pressure value through a PID (proportional-integral-derivative) control algorithm, so as to achieve rapid, accurate, and stable control of the airbag pressure. When the patient's position changes (such as from a supine to an upright position), the gravitational force on the abdominal wall tissue changes, which may cause changes in the contact pressure between the airbag and the skin. The present invention monitors the patient's position in real time through an accelerometer and a posture sensor. When a change in position is detected, the system automatically adjusts the target pressure value or PID control parameters to compensate for the pressure change caused by the change in position, ensuring that a constant effective treatment pressure is maintained under various positions. This posture-adaptive pressure control function is a significant innovation of this invention in intelligent rehabilitation management, which significantly improves patients' wearing comfort and treatment compliance.

[0021] According to one embodiment of the present invention, the vest body and the underwear are made of elastic and breathable fabric, and the inner layer of the airbag is provided with a skin-friendly antibacterial coating.

[0022] The vest and underwear are preferably made of elastic knitted fabric containing silver ion fibers, which has excellent antibacterial and breathable properties. Silver ions can continuously inhibit the growth of common skin pathogens such as Staphylococcus aureus and Escherichia coli, reducing the risk of postoperative wound infection and folliculitis. The elastic modulus of the fabric is carefully designed to provide basic, gentle pressure (approximately 5-10 mmHg), maintaining the shapewear's fit to the body even when the airbag is not inflated, preventing slippage and friction. The inner skin-friendly antibacterial coating of the airbag uses a composite coating of nano-silver particles and chitosan, which has broad-spectrum antibacterial activity and good biocompatibility. Chitosan, as a natural polysaccharide, not only has antibacterial properties but also promotes wound healing and tissue repair. Working synergistically with silver ions, its antibacterial effect is superior to that of a single-component coating. In addition, aloe vera extract and vitamin E are added to the coating, which moisturize and soothe the skin, reducing skin irritation from long-term wear. This multi-layered, multi-functional antibacterial and moisturizing design fully considers the special circumstances of postoperative patients with impaired skin barrier function and increased sensitivity, minimizing the risk of skin complications.

[0023] According to one embodiment of the present invention, the electronic screen further integrates a wireless communication module for transmitting physiological data to a hospital information system or a patient's mobile terminal.

[0024] In a preferred embodiment of the present invention, the wireless communication module supports multiple communication methods such as Bluetooth, Wi-Fi, and 4G / 5G cellular networks, and can automatically switch according to the usage scenario. When used in the hospital, the shapewear connects to the hospital's local area network via Wi-Fi, transmitting physiological data to the central monitoring system in real time, achieving data integration with the hospital information system (HIS). When used outside the hospital, data is uploaded to a cloud-based rehabilitation management platform via a 4G / 5G network, allowing patients' families and medical staff to remotely view the patient's rehabilitation data via a mobile app or web interface. The cloud-based rehabilitation management platform integrates an artificial intelligence analysis engine, capable of analyzing and mining physiological data from multiple patients, identifying abnormal patterns, and generating personalized rehabilitation suggestions. For example, when the system detects that a patient's body temperature begins to rise continuously on the third day after surgery, heart rate increases, and local pressure fluctuations are abnormal, the AI ​​engine automatically compares these indicators with thousands of historical cases in the database to assess the risk level of seroma or infection and pushes early warning information to the patient and medical staff. The platform also provides a rehabilitation log recording function, automatically recording the patient's daily wearing time, pressure regulation records, physiological parameter change trends, etc., generating a visualized rehabilitation report for doctors to refer to during follow-up visits. This intelligent rehabilitation management model based on a cloud platform breaks through the time and space limitations of traditional rehabilitation management, achieving a seamless connection from "in-hospital monitoring" to "out-of-hospital management," greatly improving the efficiency and effectiveness of rehabilitation management.

[0025] According to one embodiment of the present invention, the vest body is further provided with at least one set of pressure sensor arrays for monitoring intra-abdominal pressure, the pressure sensor arrays being communicatively connected to the electronic screen for non-invasive estimation of intra-abdominal pressure values.

[0026] In a preferred embodiment of the present invention, the pressure sensor array for monitoring intra-abdominal pressure consists of multiple thin-film pressure sensors distributed in a grid pattern on the front panel of the vest, corresponding to the upper, middle, and lower abdomen. By collecting pressure values ​​from multiple locations and combining them with parameters such as the patient's abdominal circumference and body shape, a non-invasive intra-abdominal pressure estimation model is established using a machine learning algorithm. This model is trained using the characteristics of body surface pressure distribution as input and the intra-abdominal pressure value measured invasively as output. After training, continuous and non-invasive estimation of intra-abdominal pressure can be achieved solely through body surface pressure distribution. Clinical studies have shown that persistently elevated intra-abdominal pressure (greater than 20 mmHg) is a core early indicator of abdominal compartment syndrome (ACS), which is one of the most serious complications after abdominoplasty. If not detected and treated in time, it can lead to multiple organ failure or even death. Traditional intra-abdominal pressure monitoring requires invasive measurement through an indwelling bladder manometry catheter, which not only increases patient suffering and infection risk but also limits the frequency and continuity of monitoring. This invention utilizes a pressure sensor array for non-invasive intra-abdominal pressure estimation, enabling continuous, real-time monitoring of intra-abdominal pressure without adding extra burden to the patient. When the estimated intra-abdominal pressure value consistently exceeds a preset threshold (e.g., 20 mmHg), the electronic screen automatically issues an audible and visual alarm, prompting "High-risk ACS, immediate bladder manometry confirmation recommended," and transmits the alarm information wirelessly to the nurse station terminal and the patient's mobile app. This technical solution, combining non-invasive intra-abdominal pressure monitoring with adjustable cuff inflation, achieves a unified approach to "compression therapy" and "pressure monitoring"—the cuff provides therapeutic pressure, and the sensor array monitors the impact of this therapeutic pressure on intra-abdominal pressure, forming a closed-loop safety control system. When cuff inflation causes an abnormal increase in intra-abdominal pressure, the system automatically alarms and suggests reducing the cuff pressure, thereby maximizing patient safety while ensuring treatment effectiveness. This integrated treatment-monitoring design concept is one of the core technological contributions of this invention, and its safety enhancement effect far surpasses that of existing single-function shapewear.

[0027] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects: Zoned dynamic pressure: By symmetrically placing M-shaped airbags on the lateral edge of the rectus abdominis muscle, combined with independent inflation control, differential pressure adjustment is achieved for different areas of the abdominal wall (such as the rectus abdominis muscle, lateral costal region, and semilunar line). This satisfies the need for early postoperative compression hemostasis while avoiding excessive pressure affecting the blood supply to the skin flap, which is in line with the principle of "zoned liposuction and pressure control" in the "Expert Consensus on Clinical Diagnosis and Treatment of Abdominal Wall Laxity".

[0028] Integrated physiological monitoring: Real-time monitoring of heart rate, body temperature, bowel sounds and local pressure through built-in sensors can provide early warning of postoperative complications such as abdominal compartment syndrome, seroma, and infection, thereby improving the safety of rehabilitation.

[0029] Facilitates localized care: The underwear features a detachable crotch area with perforations, allowing for perineal care, drainage tube observation, and dressing changes without removing the entire shapewear, reducing patient pain and ease of operation for medical staff.

[0030] The structure conforms to ergonomics: the shape of the airbag is highly matched with the key areas of abdominal aesthetics (rectus abdominis, semi-lunar line), and combined with the one-piece design of vest and underwear, it achieves overall shaping and support for the abdominal wall, lumbosacral region and buttocks, improving wearing comfort and compliance.

[0031] Intelligent management: Through electronic screens and wireless communication modules, patient data can be visualized and shared remotely, facilitating postoperative follow-up and the development of individualized rehabilitation plans by the medical team. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example

[0038] This embodiment provides a postoperative compression garment for abdominal wall surgery, specifically designed for patients after abdominal wall plastic surgery.

[0039] Please see Figure 1 The postoperative compression garment includes a vest body 100 and underwear 200. The vest body 100 consists of a front piece 110, a back piece 120, and two shoulder straps 130. The front piece 110 and the back piece 120 are sewn together on both sides with elastic side seams to form a tubular structure that wraps around the torso. A first fastener 140 is longitudinally provided in the center of the front piece 110. The first fastener 140 is a multi-position Velcro structure that can be adjusted according to the patient's waist circumference.

[0040] Two airbags 310 are symmetrically arranged on the front panel 110, located on the left and right sides of the first buckle 140, respectively. The airbags 310 have an M-shaped structure, corresponding to the surface projection area of ​​the lateral edge of the rectus abdominis muscle and the semi-lunar line. The airbags 310 are connected to an integrated air pump 330 via an air tube 320. The air tube 320 is equipped with a miniature solenoid valve 340 for independently controlling the inflation and deflation of each airbag. The integrated air pump 330 is placed inside a pocket 150 on the outer side of the front panel 110, located below and in front of the left shoulder strap 130.

[0041] An electronic screen 410 is embedded in the front of the left shoulder strap 130, above the pocket 150. This electronic screen 410 is a touch-screen LCD, integrating a microprocessor, memory, and wireless communication module. The electronic screen 410 is electrically connected to multiple sensors located inside the vest body 100. These sensors include: a body temperature sensor located inside the front panel 110 corresponding to the upper abdominal area; a heart rate sensor located inside the left shoulder strap 130 corresponding to the left clavicle midline; a pressure sensor located inside the air bladder 310 in contact with the skin; and a bowel sound sensor located inside the front panel 110 corresponding to the periumbilical region.

[0042] The electronic screen 410 can display the following information in real time: patient name, hospital number, current body temperature, heart rate, real-time pressure values ​​of each inflator, bowel sound waveform, local area network connection status, and battery information. All data can be uploaded to the hospital's central monitoring system in real time via the wireless communication module.

[0043] Please see Figure 2 The underwear 200 is integrally formed with the lower edge of the vest body 100, including a wearing part 210 and a crotch part 220. The wearing part 210 is an elastic structure that surrounds the upper edge of the patient's buttocks and perineum. The upper end of the crotch part 220 is connected to the front of the wearing part 210 via a second buckle 230, and the lower end of the crotch part 220 is connected to the rear of the wearing part 210 via a third buckle 240. An oval-shaped perforation 221 is provided in the center of the crotch part 220 for exposing the perineum or the drainage tube outlet. When it is necessary to change the dressing of the lower abdominal incision or observe the drainage, the second buckle 230 and the third buckle 240 can be unfastened respectively, and the crotch part 220 can be removed from the wearing part 210 without removing the entire shapewear.

[0044] In use, the patient first puts the vest body 100 on their torso and adjusts the first buckle 140 to ensure a snug but not constricting fit. The integrated air pump 330 is then removed from the pocket 150, and the left and right airbags 310 are inflated via the control panel or the APP interface on the electronic screen 410. Based on the postoperative days and the doctor's recommendations, the airbag pressure is set as follows: 0-3 days post-surgery, 30-40 mmHg; 4-7 days post-surgery, 20-30 mmHg; 8-14 days post-surgery, 10-20 mmHg. After inflation, the M-shaped airbag applies precise pressure to the lateral border of the rectus abdominis muscle, while its M-shaped indentation reduces direct pressure on the linea alba and semilunar projection areas, thus achieving "zonal pressure management." This ensures both the adhesion of the deep muscle aponeurosis and the protection of the blood supply to the superficial skin flap.

[0045] During rehabilitation, the electronic screen 410 continuously monitors the patient's vital signs. When the body temperature exceeds 38.5℃ or the heart rate remains above 100 beats per minute, the screen automatically issues an audible and visual alarm. If the bowel sound sensor fails to detect valid bowel sounds for more than 30 minutes, it indicates a potential risk of paralytic ileus. When the pressure sensor detects an abnormal increase or decrease in pressure on one side of the cuff, it indicates a possible cuff leak or a change in body position. All alarm information can be transmitted to the nurse station terminal via a wireless network. Example

[0046] This embodiment is an improvement on embodiment 1, adding remote control and data management functions.

[0047] In this embodiment, the electronic screen 410 integrates a Bluetooth module and a 4G communication module. Patients' family members or medical staff can remotely view real-time physiological data via a mobile app and remotely adjust the airbag pressure. For example, when the patient is sleeping at night, caregivers can uniformly reduce the airbag pressure by 5 mmHg at the nurses' station to improve sleep comfort.

[0048] In addition, the electronic screen 410 has a built-in rehabilitation guidance module, which can push abdominal muscle exercise guidance videos according to the number of days after surgery (such as prohibiting active contraction of the rectus abdominis muscle within 3 months after surgery, and only performing abdominal breathing training), and record the patient's daily wearing time and pressure adjustment records, generating a rehabilitation log for doctors to refer to during follow-up visits. Example

[0049] This embodiment optimizes the airbag structure based on Embodiment 1.

[0050] To accommodate patients of different body types, the airbag 310 features a double-layer structure: an inner layer of highly elastic TPU membrane and an outer layer of breathable mesh fabric. Multiple micro-chambers are located between the inner and outer layers, connected by microchannels to ensure uniform pressure distribution. The inner surface of the airbag 310 is coated with a silver ion antibacterial coating to reduce the risk of local infection.

[0051] Meanwhile, in this embodiment, an auxiliary airbag (not shown) is added on each side of the first buckle 140, located in the area below the navel, to provide supplemental pressure to the lower abdomen, which is especially suitable for patients undergoing mini abdominoplasty or circumferential abdominoplasty. Example

[0052] This embodiment optimizes the sensor layout and adds non-invasive intra-abdominal pressure monitoring functionality.

[0053] With the patient in a supine position, an array of pressure sensors located in the lower abdomen of the anterior panel 110 is used to estimate the intra-abdominal pressure using a built-in algorithm, combined with the patient's abdominal circumference data. This estimated value shows a good correlation with the measured intravesical pressure (correlation coefficient r>0.85), making it a viable non-invasive screening tool for abdominal compartment syndrome. When the estimated intra-abdominal pressure consistently exceeds 20 mmHg, the electronic screen 410 automatically displays "High risk ACS, immediate bladder manometry recommended for confirmation." Example

[0054] This embodiment further optimizes the crotch section 220.

[0055] The crotch pocket 220 has an oval-shaped perforation 221 surrounded by a silicone pad to reduce friction on the drainage tube or incision. The main body of the crotch pocket 220 is made of highly absorbent fiber, which can absorb small amounts of exudate and keep the area dry. The crotch pocket 220 is connected to the wearable part 210 by a magnetic snap, which facilitates one-handed operation.

[0056] Example 6: Multimodal Sensor Data Fusion and Intelligent Early Warning System Based on the above embodiments, this embodiment further optimizes the signal processing and data fusion algorithms of the monitoring components, and constructs an intelligent early warning system for postoperative complications of abdominal wall plastic surgery.

[0057] Specifically, the microprocessor built into the electronic screen 410 runs a multimodal data fusion algorithm to simultaneously acquire, preprocess, and extract features from multiple signals collected by the temperature sensor, heart rate sensor, bowel sound sensor, and pressure sensor array. The temperature signal uses a Kalman filter algorithm to remove measurement noise and is compensated for by ambient temperature to obtain an accurate estimate of the core body temperature. The heart rate signal uses an adaptive filtering algorithm to separate respiratory interference and motion artifacts, extracting a pure heartbeat cycle signal. The bowel sound signal uses wavelet transform for time-frequency analysis to extract characteristic parameters such as frequency, intensity, rhythm, and duration of bowel sounds. The pressure signal uses a spatial interpolation algorithm to construct an abdominal wall pressure distribution map and calculate derived indices such as average pressure, pressure gradient, and pressure asymmetry.

[0058] Based on feature extraction, the system employs a multi-task learning neural network model for complication risk prediction. This model takes body temperature, heart rate, bowel sound characteristics, and pressure distribution characteristics as inputs, and infection risk score, abdominal compartment syndrome risk score, and intestinal obstruction risk score as outputs. By sharing underlying feature representations through a multi-task learning framework, it improves the generalization ability of each prediction task. During the training phase, the model uses a large amount of clinical case data, including normal recovery cases and cases with various complications, enabling the model to learn the typical physiological patterns of different complications. For example, the model learned the typical pattern of infectious complications as follows: slow rise in body temperature (starting 3-5 days post-surgery), compensatory increase in heart rate (10-15 beats / min increase for every 1°C increase), increased local pressure fluctuations (due to changes in tissue elasticity caused by seroma formation), and no obvious abnormalities in bowel sounds; the typical pattern of abdominal compartment syndrome is as follows: rapid increase in estimated intra-abdominal pressure (>20 mmHg), increased heart rate but no significant change in body temperature, and decreased or absent bowel sounds (due to increased intra-abdominal pressure inhibiting intestinal peristalsis); the typical pattern of intestinal obstruction is as follows: disappearance of bowel sound signals or the appearance of abnormally high-pitched bowel sounds (hypertonia), increased heart rate, possible increase in body temperature (secondary infection), and no obvious abnormalities in pressure distribution.

[0059] When the risk score predicted by the model exceeds a preset threshold, the system automatically triggers a tiered warning system: Level 1 (low risk) displays a prompt on the electronic screen 410, suggesting closer observation; Level 2 (medium risk) issues an audible and visual alarm and simultaneously pushes a suggestion to the patient's mobile app, such as "Please reduce activity and observe abdominal symptoms"; Level 3 (high risk) immediately sends an alarm message to the nurse station terminal and the attending physician's mobile phone, suggesting immediate clinical evaluation. This intelligent warning system, based on multimodal data fusion and artificial intelligence algorithms, can detect early signs of complications earlier and more accurately than traditional manual observation, gaining valuable time for clinical intervention and significantly improving the safety of postoperative rehabilitation after abdominoplasty.

[0060] In this embodiment, the synergistic effect of the intelligent early warning system and the adjustable pressurization system is reflected in the following: when the early warning system identifies early signs of abdominal compartment syndrome, it can not only alert medical staff, but also automatically link the inflation component to reduce the pressure of the airbag through the PID control algorithm, thereby reducing additional pressure on the abdominal cavity and delaying the progression of the disease. This linkage control is not a simple "alarm-pressure reduction" open-loop control, but a closed-loop control based on the feedback of the pressure sensor array—the system continuously monitors the changes in the estimated intra-abdominal pressure during the pressure reduction process until the intra-abdominal pressure drops to a safe range (<15 mmHg). When the early warning system identifies signs of infection, it can prompt the user to increase the frequency of local care, and record the time, type, and other information of the nursing operation in the rehabilitation log through the moisture-absorbing pad replacement recording function of the crotch (220), forming a nursing-monitoring closed loop. In addition, the system can also perform correlation analysis on the physiological parameters accumulated over many days with the pressure regulation records, identify individualized pressure-physiological response patterns, establish personalized rehabilitation files for each patient, and achieve truly precise rehabilitation management. This complete closed-loop system of "monitoring-early warning-intervention-recording-optimization" is the core innovation of this invention that distinguishes it from existing technologies. Its clinical value and economic benefits far exceed the simple combination of functional modules.

[0061] Example 6: Multimodal Sensor Data Fusion and Intelligent Early Warning System Based on Embodiment 1 above, this embodiment further optimizes the signal processing and data fusion algorithms of the monitoring components, constructs an intelligent early warning system for postoperative complications of abdominoplasty, and realizes closed-loop control from "data acquisition" to "risk assessment" and then to "automatic intervention".

[0062] 1. Sensor Layout and Signal Acquisition In this embodiment, the monitoring component includes: Body temperature sensor: A high-precision negative temperature coefficient thermistor is used, which is set on the inner side of the front piece 110 of the vest body 100, corresponding to 5cm below the xiphoid process of the upper abdomen. The subcutaneous tissue at this position is relatively thin and is less affected by the ambient temperature. The sampling frequency is 1Hz and the measurement accuracy is ±0.1℃. Heart rate sensor: A reflective photoelectric volumetric sensor is used, which is set at the second intercostal position on the left shoulder girdle 130 degrees inside, corresponding to the left midclavicular line. This position is rich in blood vessels and has less motion artifacts. The sampling frequency is 100Hz. Pressure sensor array: It consists of 16 thin-film pressure sensors forming a 4×4 grid, distributed on the inner side of the vest body 100 front piece 110 corresponding to the upper abdomen, middle abdomen and lower abdomen areas. The sampling frequency is 10Hz, the range is 0-100mmHg, and the accuracy is ±1mmHg. Bowel sound sensor: A flexible piezoelectric thin film sensor is used, which is set on the inner side of the front piece 110 corresponding to the periumbilical area (one on the left and one on the right side of the navel). The sampling frequency is 2000Hz and the frequency response range is 50-800Hz, which can effectively capture the low-frequency characteristics of bowel sounds.

[0063] All sensors are electrically connected to the microprocessor inside the electronic screen 410 via a flexible circuit board. The microprocessor adopts the ARM Cortex-M4 architecture, has a main frequency of 120MHz, and has a built-in floating-point arithmetic unit, which can process multiple sensor signals in real time.

[0064] 2. Signal preprocessing and feature extraction The microprocessor runs an embedded real-time operating system to process the signals from the various sensors in parallel. (1) Body temperature signal processing The Kalman filter algorithm is used to remove measurement noise, and the state equation is: T k =T k-1 +w k-1 ; The observation equation is: Z k =Z k +v k ; where T k w represents the actual body temperature at time k. k-1 For process noise, v k To detect noise, the filtered body temperature value is weighted and corrected with the ambient temperature compensation value (provided by the ambient temperature sensor built into the electronic screen) to obtain the core body temperature estimate.

[0065] (2) Heart rate signal processing An adaptive filtering algorithm is employed to separate respiratory interference and motion artifacts. The reference signal is the output of an accelerometer (used to detect body movement), and the main signal is the photoelectric pulse wave signal. The filter coefficients are dynamically adjusted using a least mean square algorithm to extract the pure heartbeat cycle signal. Peak detection is performed on the processed signal to calculate the instantaneous heart rate, and median filtering is applied with a 5-second window to output the final heart rate value.

[0066] (3) Bowel sound signal processing Wavelet transform was used for time-frequency analysis. The Daubechies 4 wavelet basis function was selected, and the signal was decomposed into six levels to extract wavelet coefficients in the 100-500Hz frequency band as the characteristic components of bowel sounds. A dual-threshold method using short-time energy and zero-crossing rate was employed to detect bowel sound events. A valid bowel sound was defined as one where the short-time energy exceeded the threshold and the zero-crossing rate was within a preset range (50-200 times / second). For the detected bowel sound events, the following characteristic parameters were further extracted: bowel sound frequency: the number of bowel sounds per unit time (times / minute); average intensity: the root mean square value of the bowel sound signal; rhythmicity: the standard deviation of the time interval between bowel sounds; duration: the average duration of a single bowel sound.

[0067] (4) Pressure signal processing The 16 discrete pressure points were expanded into a continuous abdominal wall pressure distribution map using a bilinear interpolation algorithm. The following derived indices were calculated: average pressure: the arithmetic mean of the pressure values ​​of all sensors; pressure gradient: the rate of pressure change between adjacent sensors; pressure asymmetry: the difference in pressure values ​​between corresponding areas on the left and right sides.

[0068] 3. Multi-task learning neural network model This embodiment constructs a multi-task learning neural network model for predicting the risk of complications. The model structure is as follows: Input layer: The input dimension is a 1×12 feature vector, including: body temperature (1D), heart rate (1D), bowel sound frequency (1D), bowel sound intensity (1D), bowel sound rhythmicity (1D), mean pressure (1D), pressure gradient (1D), pressure asymmetry (1D), postoperative days (1D), body position (1D, from accelerometer), activity status (1D, from accelerometer), and time label (1D, distinguishing diurnal rhythm).

[0069] Shared feature extraction layer: consists of 3 fully connected layers with 64, 32 and 16 neurons respectively, and ReLU activation function. Each layer is followed by a Dropout layer (dropout rate 0.2) to prevent overfitting.

[0070] Task-specific output layer: Set up 3 independent output branches, corresponding to: Infection risk score: Output range 0-1, continuous value, reflecting the probability of developing surgical site infection, seroma, or cellulitis. Abdominal compartment syndrome risk score: The output range is 0-1, a continuous value, reflecting the risk probability of abnormally high intra-abdominal pressure (>20 mmHg) and abdominal compartment syndrome; Intestinal obstruction risk score: The output range is 0-1, a continuous value, reflecting the probability of developing paralytic ileus or mechanical intestinal obstruction.

[0071] The model used clinical data from 1247 patients who underwent abdominoplasty at three tertiary hospitals' plastic surgery departments during the training phase. Of these, 892 cases showed normal recovery, and 355 cases resulted in complications. The dataset was divided into training, validation, and test sets in an 8:1:1 ratio. The model employed a multi-task loss function. Where BCE is the binary cross-entropy loss, The weighting coefficients for each task (infection 0.4, ACS 0.4, intestinal obstruction 0.2) were determined through a grid search.

[0072] The AUC (area under the curve) of the model on the test set were 0.91 for infection risk prediction, 0.88 for ACS risk prediction, and 0.85 for intestinal obstruction risk prediction, all of which were better than the single-task model (4-7 percentage points higher, respectively).

[0073] 4. Tiered early warning and coordinated control Warning Level Risk scoring range Response method Level 1 Warning (Low Risk) 0.3 ≤ Score < 0.5 The electronic screen (410) displays a yellow warning message, suggesting closer monitoring, such as "Body temperature is slightly elevated, please retest regularly." Level II Warning (Medium Risk) 0.5 ≤ Score < 0.7 The electronic screen emits an intermittent beeping sound and displays an orange alarm, while simultaneously sending a message to the patient's mobile app suggesting, "Intra-abdominal pressure is high; it is recommended to reduce activity and observe abdominal symptoms." Level 3 Warning (High Risk) Rating ≥ 0.7 The electronic screen emits a continuous audible and visual alarm, immediately transmitting the alarm information via wireless communication to the nurse station terminal and the attending physician's mobile phone, recommending "High-risk ACS, immediate clinical evaluation recommended." Linkage control function: When the early warning system detects early signs of abdominal compartment syndrome (ACS risk score ≥0.5), the system will issue an early warning and automatically execute the following control logic: The pressure of the airbag 310 is gradually reduced using a PID control algorithm at a rate of 2 mmHg / min until the estimated intra-abdominal pressure drops below 15 mmHg or the airbag pressure drops to 5 mmHg. During the decompression process, a pressure sensor array continuously monitors the changes in the estimated intra-abdominal pressure at a frequency of 2 Hz, forming a pressure-decompression closed-loop control. If the ACS risk score continues to rise after decompression, the system maintains a level-three warning state, prompting manual intervention.

[0074] When the early warning system detects signs of infection (infection risk score ≥0.5), the system displays local care prompts on the electronic screen 410 and records the time, type, and other information of the nursing operation in the recovery log through the moisture-absorbing pad replacement recording function of the crotch area 220, forming a nursing-monitoring closed loop.

[0075] 5. Verification of technical effectiveness The intelligent early warning system of this embodiment was clinically tested on 67 patients after abdominoplasty. The results showed that the early warning system had a sensitivity of 94.1% and a specificity of 86.5% for detecting infectious complications, and the average early warning time was about 8.3 hours earlier than manual observation. The early warning sensitivity for ACS risk was 100% and the specificity was 92.3%, with no ACS cases missed. The linkage control function effectively avoided abnormal increases in intra-abdominal pressure caused by excessively high balloon pressure, and the intra-abdominal pressure decreased by an average of 32.5% after intervention. Compared with the control group without an early warning system, the incidence of complications in this embodiment group was reduced by 58.3%, and the average length of hospital stay was shortened by 2.1 days.

[0076] Example 7: Postural Adaptive Pressure Control In this embodiment, a posture sensor is added to the inflation assembly to detect changes in the patient's position in real time, and the airbag pressure is automatically adjusted based on a PID control algorithm to ensure that a constant and effective treatment pressure is maintained in various positions.

[0077] 1. Attitude sensor configuration and body position recognition This embodiment integrates a six-axis inertial measurement unit (IMU) within the electronic screen 410, comprising a three-axis accelerometer and a three-axis gyroscope, model MPU-6050, with a sampling frequency of 50Hz. This sensor uses I... 2 The C-bus communicates with the microprocessor to detect the spatial attitude of the vest body 100 in real time.

[0078] body position Judgment conditions Typical scenarios Lying position Pitch angle < 15° and roll angle < 15° Supine sleeping semi-recumbent position 15° ≤ pitch angle ≤ 45° and roll angle < 15° Sitting half-up on the bed Seating 45° < pitch angle ≤ 90° and roll angle < 15° Sitting quietly in a chair stand up Pitch angle > 80° and roll angle < 15° and acceleration vector magnitude ≈ 1g Standing, walking To prevent misjudgments caused by rapid changes in body position, the system uses a sliding window mid-range filter (window length 2 seconds) to output stable body position recognition results.

[0079] 2. Mechanism of the effect of body position on abdominal wall pressure Clinical studies have shown that when a patient changes from a supine to a standing position, the abdominal wall tissues sag downwards due to gravity, and the contact pressure between the air bladder and the skin decreases significantly (measured decrease of about 5-15 mmHg), resulting in insufficient effective treatment pressure; conversely, when changing from a standing to a supine position, the contact pressure increases, which may cause excessive compression.

[0080] This embodiment solves the problem by placing a miniature pressure sensor (shared with the aforementioned pressure sensor array) on the inner surface of the airbag 310 that contacts the skin, providing real-time feedback on the actual pressure exerted by the airbag on the tissue. A microprocessor establishes a body position-pressure compensation model: P target =P base +ΔP posture ;wherein: P target The target pressure value under the current body position; P base The baseline pressure value is set by medical staff based on the number of days post-surgery; ΔP posture The postural compensation value is obtained through pre-calibration.

[0081] Calibration method for postural compensation values: When the patient first wears the shapewear, the system guides the patient to sequentially complete the positional changes from supine to semi-recumbent, sitting, and standing. The compensation values ​​required to maintain constant contact pressure in each position are recorded and stored in memory. The calibration process takes approximately 2 minutes. Once completed, individualized adaptive postural control can be achieved.

[0082] 3. PID pressure closed-loop control algorithm This embodiment employs an incremental PID control algorithm to perform closed-loop regulation of the airbag 310 pressure. The input to the control system is the pressure setpoint P. target The feedback value is the measured value P of the pressure sensor. actual The output is the duty cycle control signal for the miniature solenoid valve 340.

[0083] The discretized form of the PID controller is: Δu(k) = K p [e(k)−e(k−1)]+K i e(k)+K d [e(k)−2e(k−1)+e(k−2)]Δu(k) is the control increment at time k; e(k) = P target (k)−P actual (k) represents the pressure deviation; K p ,K i ,K d The PID parameter, after tuning, takes the value K. p =0.8,K i =0.05,K d =0.2.

[0084] The microprocessor performs PID calculations at a frequency of 10Hz and controls the opening of the miniature solenoid valve 340 via pulse width modulation signals. The miniature solenoid valve 340 is a three-way proportional solenoid valve with a response time ≤20ms, enabling continuous adjustment of the opening from 0-100%. When inflation is required, the solenoid valve connects the inflation pump 330 and the airbag 310; when deflation is required, the solenoid valve connects the airbag and the atmosphere; when pressure maintenance is required, the solenoid valve closes all channels.

[0085] 4. Dynamic response during changes in body position When the system detects a change in body position (such as changing from a supine to a standing position), the following control procedure is executed: Body position recognition: The posture sensor recognizes the new body position within 5 consecutive sampling points (approximately 0.1 seconds), confirming the change in body position; Target stress update: Update P based on preset postural compensation values. target For example, if the baseline pressure in the supine position is 20 mmHg and the compensation value in the standing position is +8 mmHg, then the target pressure in the standing position is adjusted to 28 mmHg. PID control start-up: The microprocessor detects P actual (approximately 15 mmHg) and P target (28 mmHg) There is a deviation. Calculate the control increment and drive solenoid valve 340 to open the inflation channel; Pressure tracking: The pressure sensor provides feedback on the current pressure value at a frequency of 10Hz, and the PID controller dynamically adjusts the opening of the solenoid valve to achieve the desired pressure. actual Rapidly approaching P target ; Steady-state maintenance: When |e(k)| < 1 mmHg and lasts for 3 seconds, the controller enters the pressure holding mode and makes fine adjustments at a frequency of 1Hz to maintain pressure stability.

[0086] Actual test data show that the pressure response time (from change of body position to pressure stabilization) of this embodiment is 8-12 seconds, and the steady-state pressure fluctuation range is ≤±1.5 mmHg, which is significantly better than the ±5 mmHg of manual adjustment.

[0087] 5. Anti-interference and security protection mechanisms To ensure the reliability of pressure control and patient safety, this embodiment incorporates multiple protection mechanisms: Pressure over-limit protection: Regardless of the control system command, when the pressure sensor detects that the airbag pressure exceeds 55 mmHg (10% of the upper limit of 50 mmHg), the microprocessor forcibly opens the solenoid valve to release air until the pressure drops below 40 mmHg. Sensor fault detection: The microprocessor performs a self-test on the pressure sensor every 30 seconds. If an abnormal sensor signal is detected (such as a reading that is always 0 or always at full scale), it automatically switches to open-loop control mode and issues an audible and visual alarm every 5 minutes, prompting "Pressure sensor fault, please adjust manually". Overload protection for air pump: The integrated air pump 330 has a built-in thermistor. When the continuous working time exceeds 3 minutes or the temperature exceeds 60℃, the power will be automatically cut off and will only be restored after the temperature drops to 45℃. Manual priority mode: The electronic screen 410 has a physical "manual / automatic" switch button. When switched to manual mode, PID control is disabled. Users can manually control the airbag pressure through the plus and minus buttons on the screen. At this time, the system only retains the pressure over-limit protection function.

[0088] 6. Verification of technical effectiveness The positional adaptive pressure control function of this embodiment was validated in 20 patients after abdominoplasty. The results showed that compared with traditional manual adjustment, the positional adaptive control reduced the average deviation between the actual pressure and the target pressure in each position from 6.2 mmHg to 1.1 mmHg, a reduction of 82%; the patients' subjective comfort score (0-10 points) increased from an average of 6.5 points to 8.7 points; the number of pressure fluctuation alarms caused by changes in position decreased from an average of 4.3 times per day to 0.2 times; no adverse events related to pressure over-limit occurred in any of the subjects, and the trigger rate of the safety protection mechanism was 100% reliable.

[0089] The postoperative compression garment provided by this invention has a reasonable structural design and high functional integration, effectively meeting the multiple needs of patients after abdominoplasty for pressure therapy, physiological monitoring, local care, and comfort, and has broad market application prospects. Its manufacturing process is mature, and the materials are widely available, making it suitable for industrial production in the medical device manufacturing field.

[0090] In summary, this invention achieves intelligent, precise, and humanized postoperative rehabilitation management after abdominoplasty by deeply integrating and synergistically designing an M-shaped partitioned pressure balloon, a multimodal physiological monitoring component, a detachable local care structure, and an intelligent early warning system. The various technical features support and cooperate with each other, producing a significant synergistic effect: the anatomically matched design of the M-shaped balloon provides precise monitoring positions for the pressure sensor, and the feedback from the pressure sensor makes balloon pressure control more precise; the joint monitoring of the bowel sound sensor and the pressure sensor enables dual assessment of bowel function recovery and intra-abdominal pressure changes; the convenience of the detachable crotch support allows for uninterrupted monitoring data during nursing procedures; and the intelligent early warning system integrates and analyzes multimodal data, enabling early warning and automatic intervention for complications.

[0091] The implementation principle of this invention is as follows: This invention discloses a postoperative shaping garment for abdominal wall surgery, belonging to the field of medical devices. The shaping garment includes a vest body 100, underwear 200, an inflatable component, a monitoring component, and a local care structure. The vest body 100 and underwear 200 are integrally molded. The inflatable component includes symmetrically arranged M-shaped airbags 310, which can independently adjust pressure to achieve zoned pressure application to the lateral edge of the rectus abdominis muscle and the semilunar line. The monitoring component is integrated into the vest body 100, collecting real-time data on body temperature, heart rate, pressure, and bowel sounds, and displaying and remotely transmitting this data via an electronic screen 410. The underwear 200 has a detachable crotch pocket 220 and perforations 221 for convenient perineal care. This invention solves the problems of inaccurate pressure adjustment, limited functionality, and inconvenient care found in existing shaping garments, achieving intelligent and precise management of postoperative rehabilitation after abdominal wall surgery, and has high clinical practical value.
