Description

Technical Field

[0001] This invention relates to the field of intelligent pressure adjustment technology for abdominal binders, and in particular to an intelligent pressure adjustment method and system for abdominal binders used in postoperative rehabilitation. Background Technology

[0002] With advancements in abdominal surgical techniques, open surgery, laparoscopic surgery, and minimally invasive procedures are becoming increasingly common. Postoperative abdominal binders, used to apply pressure and support to the abdomen, have become a routine auxiliary method to aid wound healing, prevent dehiscence, and reduce complications. Currently, most common abdominal binders are made of elastic fabric or adjustable straps, and their main function is to provide continuous external force to the abdomen, restricting abdominal movement, reducing wound tension, and thus alleviating postoperative pain.

[0003] In recent years, with the development of wearable devices and smart sensing technology, some abdominal binders have begun to incorporate pressure sensors, electronic adjustments, or airbag structures to monitor and adjust the pressure applied to the abdomen, gradually making postoperative rehabilitation aids more intelligent. However, overall, existing technologies still mainly rely on static or semi-static pressure application methods, and pressure adjustment largely depends on the experience of medical staff or simple mechanical structures. A mature method that can systematically, automatically, and in a closed loop adjust the pressure based on the patient's actual pressure state has not yet been developed.

[0004] Current technologies still have many shortcomings in practical applications of postoperative rehabilitation:

[0005] First, most abdominal binders lack differentiated pressure control for different surgical types and different areas of the abdomen. Often, the entire abdomen is treated with the same tightness, but the support needs of the upper, middle, and lower abdomen after surgery vary. This easily leads to some areas being under-compressed while others are over-compressed. Second, once the abdominal binder is applied, it's impossible to continuously monitor actual pressure changes. Patient breathing, turning over, or daily activities all cause pressure fluctuations, but medical staff often cannot detect these in time, resulting in pressure deviating from the ideal range for extended periods.

[0006] Although some intelligent adjustment solutions have emerged, most can only adjust a single parameter or only provide local control. They suffer from problems such as complex control logic, insufficient stability, and inconsistent adjustment, and are still difficult to meet the actual clinical requirements of "stability, continuity, and controllability" in the postoperative rehabilitation process. Summary of the Invention

[0007] In view of the aforementioned existing problems, the present invention is proposed.

[0008] Therefore, this invention provides an intelligent pressure adjustment method and system for postoperative abdominal binders, which solves the problems of existing postoperative abdominal binder technologies, such as crude pressure control, lack of closed-loop regulation, and inability to balance overall stability and local key support.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0010] In a first aspect, the present invention provides a method for intelligent pressure adjustment of an abdominal binder for postoperative rehabilitation, comprising,

[0011] After abdominal surgery, a smart abdominal binder is put on the patient and the corresponding postoperative rehabilitation mode is selected. Based on this, the target pressure parameters are loaded and the initialization settings are completed.

[0012] The pressure acquisition unit inside the abdominal binder continuously collects the pressure status of various areas of the abdomen, forming real-time pressure data. The pressure data is compared with the target pressure range to determine the current pressure status and generate a pressure adjustment command.

[0013] According to the pressure adjustment command, the overall tightness is adjusted through the pressure adjustment structure of the abdominal belt so that the abdominal pressure gradually reaches the set range. After the overall pressure meets the requirements, local pressure compensation is performed on the incision or key areas, and the pressure status is retested at the same time to confirm the adjustment result.

[0014] During stable pressure operation, the pressure fluctuations caused by changes in patient position and activity are continuously monitored, and adaptive adjustments are made as needed.

[0015] As a preferred embodiment of the intelligent pressure adjustment method for abdominal binders in postoperative rehabilitation according to the present invention, the steps are as follows: After abdominal surgery, the patient wears an intelligent abdominal binder and selects the corresponding postoperative rehabilitation mode, thereby loading the target pressure parameter and completing the initialization settings.

[0016] After abdominal surgery, the patient wears and powers on the smart abdominal belt. Medical staff select the corresponding postoperative rehabilitation mode, and the system automatically loads the target pressure range and safety threshold of the upper, middle and lower abdomen from the built-in surgical procedure database. It also calculates the central control pressure of each monitoring point and completes the initial setting of closed-loop pressure regulation control.

[0017] As a preferred embodiment of the intelligent pressure regulation method for abdominal binders in postoperative rehabilitation according to the present invention, the steps for generating real-time pressure data are as follows:

[0018] After completing the initial setup, medical staff placed the three pressure sensors on the inside of the abdominal binder in the standard positions of the upper, middle and lower abdomen, and secured the abdominal drainage tube to the outside to ensure accurate pressure on the sensors and that they were not interfered with by the catheter. After confirming the placement, real-time sampling was started to continuously collect the actual pressure status of each area of ​​the abdomen and form three points of real-time pressure data to generate a real-time pressure sequence.

[0019] As a preferred embodiment of the intelligent pressure regulation method for abdominal binders in postoperative rehabilitation according to the present invention, the steps of determining the current pressure status and generating a pressure regulation command are as follows:

[0020] After completing the initial fitting pressure calibration and confirming the validity of the real-time pressure data, the collected three-point real-time pressure data are compared with the corresponding target pressure range point by point to calculate the deviation of the current pressure of each abdominal region relative to the target center value.

[0021] Based on the pressure deviation, it is determined whether each monitoring area is in a state of high pressure, low pressure, or target stability, and a clear pressure regulation control command is generated to guide the abdominal belt to perform pressure regulation operations such as tightening, loosening, or maintaining.

[0022] As a preferred embodiment of the intelligent pressure adjustment method for abdominal binders in postoperative rehabilitation described in this invention, the steps for adjusting the overall tightness of the abdominal binder through its pressure adjustment structure are as follows:

[0023] After completing the pressure state determination and generating the pressure adjustment command, the pressure adjustment structure inside the abdominal belt is driven to adjust the overall tightness of the abdominal belt according to the pressure adjustment command, so that the abdominal belt is tightened or loosened evenly in the circumferential direction.

[0024] As a preferred embodiment of the intelligent pressure adjustment method for abdominal binders in postoperative rehabilitation as described in this invention, the steps of performing local pressure compensation on the incision or key areas and simultaneously re-measuring the pressure status to confirm the adjustment result are as follows:

[0025] After the overall pressure adjustment is completed, the pressure status of the three points of the abdominal binder is continuously monitored. When the pressure of each monitoring point remains within the allowable error range for multiple consecutive sampling cycles, it is determined that the overall pressure has stabilized and met the standard, and the local compensation function is automatically unlocked. After the overall pressure stabilizes, medical staff adjust and fix the movable micro-airbag on the inside of the abdominal binder to the corresponding key area according to the surgical incision location or bleeding risk area, so that it fits the local skin and does not affect the working status of the existing pressure sensor.

[0026] After the airbag is positioned, the medical staff inflates the airbag according to the compensation parameters preset in the procedure, so that the key area can obtain additional local support pressure on the basis of the original overall pressure.

[0027] After local compensation is completed, the original pressure sampling frequency is maintained, and the overall three-point pressure and local area pressure status are re-measured simultaneously to confirm that local pressurization has not disrupted the overall pressure stability and that the local pressure has reached the expected compensation level. When the re-measurement results show that the overall pressure is still in the stable range and the local compensation is effective, the current abdominal pressure distribution is taken as the final adjustment result.

[0028] As a preferred embodiment of the intelligent pressure adjustment method for abdominal binders in postoperative rehabilitation according to the present invention, the adaptive adjustment when needed includes:

[0029] During stable pressure operation, real-time pressure data of each area of ​​the abdominal binder is continuously collected, and pressure changes caused by the patient turning over, getting up, or moving are monitored. When a short-duration instantaneous pressure fluctuation is detected, it is determined to be a transient effect caused by a change in body position. No pressure adjustment operation is performed, and the pressure recovery is monitored. If the pressure deviates from the stable range and continues to exceed the set time window, it is determined that the current pressure state has changed. The adaptive adjustment mechanism is then triggered, and the overall tightness of the abdominal binder is adjusted slightly through the pressure adjustment structure to bring the pressure back to the stable range.

[0030] Secondly, this invention provides an intelligent pressure regulating system for postoperative abdominal binders, comprising,

[0031] The parameter initialization module is used to load the target pressure parameters and safety thresholds of the corresponding postoperative rehabilitation mode after the patient wears the abdominal binder, and to complete the initialization settings of the abdominal binder pressure control.

[0032] The pressure acquisition module is used to continuously collect the pressure status of various areas of the abdomen through pressure sensors inside the abdominal binder, forming real-time pressure data;

[0033] The status determination and pressure regulation command generation module is used to compare real-time pressure data with the target pressure range, determine the current pressure status, and generate corresponding pressure regulation control commands.

[0034] The overall pressure adjustment execution module is used to drive the abdominal belt pressure adjustment structure to uniformly adjust the overall tightness of the abdominal belt according to the pressure adjustment command, so that the abdominal pressure gradually reaches the set range.

[0035] The local compensation and adaptive adjustment module is used to compensate for local pressure in incisions or key areas after the overall pressure has stabilized, and to monitor pressure fluctuations caused by changes in body position during operation and make adaptive adjustments when necessary.

[0036] Thirdly, the present invention provides a computer device including a memory and a processor, wherein the memory stores a computer program, wherein: when the computer program is executed by the processor, it implements any step of the intelligent pressure adjustment method for abdominal binders for postoperative rehabilitation as described in the first aspect of the present invention.

[0037] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein: when the computer program is executed by a processor, it implements any step of the intelligent pressure adjustment method for abdominal binders for postoperative rehabilitation as described in the first aspect of the present invention.

[0038] The beneficial effects of this invention are as follows: By combining parametric management of surgical procedures with real-time closed-loop pressure control, precise and dynamic adjustment of overall and local abdominal pressure is achieved. Compared with existing abdominal binder techniques that rely on manual experience or static adjustment, this invention can automatically determine pressure deviations and generate pressure adjustment commands based on the real-time pressure status of different areas of the abdomen, gradually stabilizing the overall pressure of the abdominal binder within a safe and effective target range, significantly reducing the probability of excessive compression or insufficient support. Simultaneously, this invention introduces a localized key area compensation mechanism on the basis of achieving the overall pressure target, allowing for targeted pressure application to incisions or high-risk areas without compromising overall stability, which is beneficial for promoting incision healing and reducing complications such as bleeding. Furthermore, by continuously monitoring and adaptively adjusting pressure fluctuations caused by changes in body position and activity, this invention effectively improves the continuity and reliability of abdominal binder pressure management during postoperative recovery, reduces the need for frequent manual adjustments by medical staff, and enhances the safety and standardization of postoperative care.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0045] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a method for intelligent pressure adjustment of an abdominal binder for postoperative rehabilitation, including the following steps:

[0046] S1. Put a smart abdominal binder on the patient after abdominal surgery and select the corresponding postoperative rehabilitation mode. Load the target pressure parameters and complete the initialization settings accordingly.

[0047] Specifically, when the patient completes abdominal surgery and is about to wear the abdominal binder, the medical staff presses the power button on the abdominal binder control box to power on the abdominal binder, start it up, enter the initialization state, and automatically clear the operating parameters of the previous patient in preparation for loading the new postoperative rehabilitation control configuration.

[0048] After initialization, enter the "Postoperative Rehabilitation Mode Selection Interface" on the display screen or APP. Medical staff can select and confirm the unique abdominal surgery type / postoperative rehabilitation mode by scrolling through the interface, and lock the mode as the only control mode for this abdominal binder.

[0049] After the postoperative rehabilitation mode is confirmed, the built-in surgical pressure database is automatically invoked to read the three target pressure ranges and safety threshold parameters corresponding to the selected mode, and to generate target pressure ranges for three monitoring points in the upper abdomen, middle abdomen, and lower abdomen. Simultaneously, a global safety high-pressure threshold is generated. With global low-pressure warning threshold ;

[0050] After completing the target range reading, the control center pressure corresponding to each monitoring point is calculated. :

[0051]

[0052] In the formula, It is the lower bound of the target at point i. It is the upper limit of the target at point i;

[0053] After the parameters are fixed, the name of the currently loaded postoperative rehabilitation mode, the three-point target pressure range and the safety threshold are displayed on the screen or APP, and an initialization verification record is generated; after the medical staff confirms that there are no errors, the "initialization completed" status is marked.

[0054] S2. The pressure acquisition unit inside the abdominal binder continuously collects the pressure status of various areas of the abdomen to form real-time pressure data. The pressure data is compared with the target pressure range to determine the current pressure status and generate a pressure adjustment command.

[0055] Specifically, the steps to generate real-time pressure data are as follows:

[0056] The medical staff first moved the first thin-film pressure sensor on the inside of the abdominal binder to the standard position on the patient's upper abdomen, about 2 cm below the xiphoid process, and gently attached the abdominal binder to the abdominal wall to ensure that the sensor is in full contact with the skin. During the application process, it was confirmed that the skin in this area was flat, without wrinkles or dressings, to ensure that the sensor's pressure surface was completely in contact with the abdominal wall. This completed upper abdominal application is a prerequisite for the placement of the sensor in the middle abdomen.

[0057] After confirming the upper abdominal sensor placement, medical staff placed the second thin-film pressure sensor within approximately 1 cm of the umbilicus, positioning it on the midline of the abdomen, and repeated the placement confirmation process to ensure there were no air gaps or folds between the sensor and the skin. After completing the placement of the mid-abdomen sensor, the system marked "Mid-abdomen ready" in the background, which serves as the trigger condition for the placement of the lower abdominal sensor.

[0058] After confirming the mid-abdomen position, the medical staff moved the third thin-film pressure sensor to the standard position in the lower abdomen, about 3cm above the pubic symphysis, and performed the same fitting check to ensure it was stably attached to the abdominal wall.

[0059] After all three sensors are in place, medical staff will conduct a complete inspection of the abdominal drainage tube area to confirm that no sensor covers the drainage outlet or compresses the catheter. Then, the drainage tube will be arranged along the outside of the abdominal band and fixed to the outside of the abdominal band with medical tape to physically isolate it from the pressure regulating structure inside the abdominal band, so as to avoid pulling on the catheter when the abdominal band contracts or relaxes.

[0060] After the drainage tube is fixed, the medical staff press the "Confirm Fit" command on the display screen or APP to perform a quick self-check on the contact status of the three sensors. When the signals at all three points are within the effective range, a "Placement Complete" mark is generated, which serves as a direct trigger signal to start real-time sampling.

[0061] After the "Deployment Complete" marker is generated, the pressure acquisition module is automatically activated, and the pressure at the three points is synchronously sampled at a fixed sampling frequency to form a real-time pressure sequence. .

[0062] Furthermore, the current pressure status is determined and a pressure regulation command is generated. The steps are as follows:

[0063] Medical staff first make an initial adjustment to the tightness of the abdominal binder using the basic Velcro straps. The adjustment standard is that two fingers can be stably inserted between the abdominal binder and the abdominal wall without any obvious pressure or discomfort. This operation is to ensure that the abdominal binder is within the adjustable physical working range, and this tightness is a physical prerequisite for pressure calibration.

[0064] After completing the basic tightness adjustment, the medical staff press the "Confirm / Calibrate" button on the display screen or APP to immediately enter the calibration mode and lock a fixed calibration time window T=10 s. During this time window, the abdominal binder structure is kept in a state of no active adjustment, and only pressure data is collected.

[0065] Within the calibration time window T, the real-time pressure sequences at three points are integrally averaged to obtain the short-time average pressure at each monitoring point. And compare it with the fixed safety threshold, and perform a controllability judgment point by point: If any monitoring point satisfies:

[0066]

[0067] If the current fit is deemed unusable, the medical staff will be prompted via the display screen or APP to readjust the tightness of the Velcro; after the medical staff has made the adjustment, the calibration process will be repeated.

[0068] When all three conditions are met:

[0069]

[0070] Then it is determined that the bonding pressure is within a controllable range;

[0071] After calibration, the three points will be... Mark the effective pressure baseline for the current wearing condition, and de-calibrate to enter continuous operation mode; read the three target pressure ranges from the motherboard parameter area. And calculate a unique control center pressure for each monitoring point. Real-time pressure obtained from continuous sampling Perform point-by-point deviation calculation (using real-time pressure minus center pressure) to obtain the three-point pressure deviation. ;

[0072] Compare the pressure deviation with the preset steady-state threshold. The pressure status of each monitoring point is determined by comparison according to the following rules:

[0073] like If so, the current pressure is relatively high. If the current pressure is relatively low, then... If so, the current pressure belongs to the target stable state;

[0074] If at least one monitoring point is in an elevated state, the overall pressure trend will be judged as "needing to be relaxed";

[0075] If all monitoring points are at a low level, the overall pressure trend will be judged as "needing to be tightened";

[0076] If all monitoring points are in a stable state, the current pressure is determined to be stable, and no pressure regulation action is triggered.

[0077] When the judgment result is "needs to be tightened", a pressure adjustment command is generated to "increase the tightening amount of the abdominal binder".

[0078] When the judgment result is "needs to be relaxed", a pressure adjustment command is generated to "reduce the tightening amount of the abdominal binder".

[0079] When the determination result is "stable", a voltage regulation command to "maintain the current state" is generated.

[0080] S3. According to the pressure adjustment command, the overall tightness is adjusted through the pressure adjustment structure of the abdominal belt so that the abdominal pressure gradually reaches the set range. After the overall pressure meets the requirements, local pressure compensation is performed on the incision or key areas, and the pressure status is retested at the same time to confirm the adjustment result.

[0081] Specifically, the overall tightness is adjusted through the pressure-adjusting structure of the abdominal binder. The steps are as follows:

[0082] Upon receiving the pressure regulation command for the current cycle, the corresponding driving quantity is sent to the nickel-titanium alloy memory wire array inside the abdominal belt. This causes the memory wires to contract or release uniformly under the action of the corresponding current, thereby driving the entire abdominal belt to tighten or loosen uniformly along the circumference, thus adjusting the overall tension of the abdominal belt. Due to the use of a unified driving method, the abdominal belt maintains consistent circumferential force during the adjustment process, avoiding the problem of uneven local force. After the pressure regulation structure completes the driving action of the current cycle, the overall tension of the abdominal belt changes. This changed state of the abdominal belt is saved as the current operating state, and the system waits for the next sampling cycle to acquire new pressure data.

[0083] Furthermore, local pressure compensation is applied to the incision or key areas, and the pressure status is simultaneously re-measured to confirm the adjustment results. The steps are as follows:

[0084] After the overall pressure adjustment is completed, the pressure status of the three points of the abdominal binder is continuously monitored. When the pressure of each monitoring point remains within the allowable error range for multiple consecutive sampling cycles, it is determined that the overall pressure has stabilized and met the standard, and the local compensation function is automatically unlocked. Before this stable state is confirmed, the local airbag does not participate in pressurization to avoid interfering with the overall closed-loop pressure adjustment. After the overall stability is achieved, medical staff adjust and fix the movable micro airbag on the inside of the abdominal binder to the corresponding key area according to the surgical incision location or bleeding risk area, so that it fits the local skin and does not affect the working status of the existing pressure sensor.

[0085] After the airbag is positioned, the medical staff inflates the airbag according to the compensation parameters preset in the procedure, so that the key areas receive additional local support pressure on top of the original overall pressure, thereby enhancing the stable compression of the incision or high-risk areas.

[0086] After local compensation is completed, the original pressure sampling frequency is maintained, and the overall three-point pressure and local area pressure status are re-measured simultaneously to confirm that local pressurization has not disrupted the overall pressure stability and that the local pressure has reached the expected compensation level. When the re-measurement results show that the overall pressure is still in the stable range and the local compensation is effective, the current abdominal pressure distribution is taken as the final adjustment result.

[0087] S4. During stable pressure operation, continuously monitor pressure fluctuations caused by changes in patient position and activity, and make adaptive adjustments as needed.

[0088] Specifically, after entering the pressure stabilization operation phase, the continuous operation of each pressure acquisition unit within the abdominal binder is maintained. Data on overall abdominal pressure and local compensation area pressure are continuously acquired according to a predetermined sampling frequency, and real-time pressure changes are used as operational monitoring input. During this process, the pressure change rate and duration characteristics are simultaneously combined to identify instantaneous pressure fluctuations caused by changes in patient position such as turning over, sitting up, getting out of bed, or coughing. When a short-term pressure change is detected but its duration is below a preset threshold (set to 1-3 sampling cycles (corresponding to approximately 1-5 seconds), the value is determined to be a transient change caused by position or activity. Pressure deviations exceeding this time window often reflect changes in the actual fit or stress conditions of the abdominal binder. This setting method can be achieved through existing technologies such as conventional time-series signal stability analysis and sliding time window discrimination). In this case, the fluctuation is determined to be a transient change caused by position or activity. Pressure adjustment is not immediately triggered; instead, the current abdominal binder tightness is maintained, and pressure recovery is observed.

[0089] If the pressure at one or more pressure monitoring points deviates from the stable range and this deviation continues for more than a preset time window, it indicates that the patient's positional change has caused a substantial change in the actual pressure state of the abdominal binder. In this state, the system automatically enters the adaptive adjustment preparation state. In this state, the current pressure deviation is recalculated based on the latest collected pressure data, and the abdominal binder pressure adjustment structure is driven to make small, gradual adjustments to the overall tightness of the abdominal binder according to the established overall pressure adjustment mechanism, so that the overall abdominal pressure returns to the stable range.

[0090] After the adaptive adjustment is completed, pressure retesting is conducted to confirm the adjustment effect and then return to a stable monitoring state. Through the above continuous monitoring and adaptive adjustment process when necessary, the abdominal binder maintains appropriate support pressure during the patient's daily activities and changes in body position without frequent manual intervention, thereby achieving stable and continuous pressure management during the postoperative rehabilitation stage.

[0091] This embodiment also provides an intelligent pressure regulating system for postoperative abdominal binders, including:

[0092] The parameter initialization module is used to load the target pressure parameters and safety thresholds of the corresponding postoperative rehabilitation mode after the patient wears the abdominal binder, and to complete the initialization settings of the abdominal binder pressure control.

[0095] The overall pressure adjustment execution module is used to drive the abdominal belt pressure adjustment structure to uniformly adjust the overall tightness of the abdominal belt according to the pressure adjustment command, so that the abdominal pressure gradually reaches the set range.

[0096] The local compensation and adaptive adjustment module is used to compensate for local pressure in incisions or key areas after the overall pressure has stabilized, and to monitor pressure fluctuations caused by changes in body position during operation and make adaptive adjustments when necessary.

After local compensation is completed, the original pressure sampling frequency is maintained, and the overall three-point pressure and local area pressure status are re-measured simultaneously to confirm that local pressurization has not disrupted the overall pressure stability and that the local pressure has reached the expected compensation level. When the re-measurement results show that the overall pressure is still in the stable range and the local compensation is effective, the current abdominal pressure distribution is taken as the final adjustment result.

7. The intelligent pressure adjustment method for abdominal binders in postoperative rehabilitation as described in claim 6, characterized in that: The adaptive adjustment when needed includes: During stable pressure operation, real-time pressure data of each area of ​​the abdominal binder is continuously collected, and pressure changes caused by the patient turning over, getting up, or moving are monitored. When a short-duration instantaneous pressure fluctuation is detected, it is determined to be a transient effect caused by a change in body position. No pressure adjustment operation is performed, and the pressure recovery is monitored. If the pressure deviates from the stable range and continues to exceed the set time window, it is determined that the current pressure state has changed. The adaptive adjustment mechanism is then triggered, and the overall tightness of the abdominal binder is adjusted slightly through the pressure adjustment structure to bring the pressure back to the stable range.

8. A postoperative rehabilitation abdominal binder intelligent pressure adjustment system, based on the postoperative rehabilitation abdominal binder intelligent pressure adjustment method according to any one of claims 1 to 7, characterized in that: include, The parameter initialization module is used to load the target pressure parameters and safety thresholds of the corresponding postoperative rehabilitation mode after the patient wears the abdominal binder, and to complete the initialization settings of the abdominal binder pressure control. The pressure acquisition module is used to continuously collect the pressure status of various areas of the abdomen through pressure sensors inside the abdominal binder, forming real-time pressure data; The status determination and pressure regulation command generation module is used to compare real-time pressure data with the target pressure range, determine the current pressure status, and generate corresponding pressure regulation control commands. The overall pressure adjustment execution module is used to drive the abdominal belt pressure adjustment structure to uniformly adjust the overall tightness of the abdominal belt according to the pressure adjustment command, so that the abdominal pressure gradually reaches the set range. The local compensation and adaptive adjustment module is used to compensate for local pressure in incisions or key areas after the overall pressure has stabilized, and to monitor pressure fluctuations caused by changes in body position during operation and make adaptive adjustments when necessary.

9. A computer device comprising a memory and a processor, wherein the memory stores a computer program, characterized in that: When the processor executes the computer program, it implements the steps of the intelligent pressure adjustment method for abdominal binders for postoperative rehabilitation as described in any one of claims 1 to 7.

10. A computer-readable storage medium having a computer program stored thereon, characterized in that: When the computer program is executed by the processor, it implements the steps of the intelligent pressure adjustment method for abdominal binders for postoperative rehabilitation as described in any one of claims 1 to 7.
