Description

Technical Field

[0001] This application relates to the field of pressure monitoring technology, and in particular to a method, system, device and medium for monitoring the pressure of an ostomy abdominal binder. Background Technology

[0002] In modern medicine, especially for patients after colostomy, parastomal hernia is a relatively common and challenging complication. It mainly occurs when abdominal organs or tissues protrude from the defect next to the stoma. With an aging population and rising incidence of various intestinal diseases, the number of patients undergoing colostomy is gradually increasing, making the prevention and treatment of parastomal hernia an important clinical issue. The main manifestation of parastomal hernia is bulging of the abdominal wall next to the stoma, and standing, walking, or straining can exacerbate the symptoms. In the early stages, parastomal hernia is generally asymptomatic, but as the disease progresses, it gradually affects the patient's daily life, causing poor adhesion and leakage of the ostomy bag baseplate, increasing the difficulty of stoma care, and in severe cases, leading to intestinal adhesions, abdominal pain, intestinal incarceration or necrosis due to narrowing, and even threatening life.

[0003] Currently, after stoma surgery, doctors usually recommend that patients use a stoma abdominal binder after the initial wound healing (i.e., after the sutures or staples are removed) to provide protection and support for the stoma site, help reduce abdominal tension, promote wound healing, and reduce the likelihood of complications such as stoma prolapse and parastomal hernia by applying pressure to the entire abdomen. However, in practice, because the design of stoma abdominal binders is relatively simple, often consisting of a simple elastic material wrapped around the abdomen, they cannot precisely fit each patient's unique stoma location and body contour. This results in uneven pressure distribution, and in the critical prevention area for parastomal hernia (i.e., around the stoma), they cannot effectively prevent abdominal organs from protruding outward through the weak area next to the stoma, resulting in poor preventive effect. Summary of the Invention

[0004] To enhance the therapeutic and preventative effects of stoma abdominal binders on parastomal hernia in stoma patients, this application provides a method, system, device, and medium for monitoring stoma abdominal binder pressure.

[0005] In a first aspect, this application provides a method for monitoring the pressure of a stoma abdominal binder, employing the following technical solution: A method for monitoring stoma abdominal binder pressure, based on a stoma abdominal binder, the method comprising: Initial pressure parameters were obtained for each key area around the stoma during the initial period after the patient first wore the stoma abdominal binder. The average reference threshold is obtained based on all initial pressure parameters; The system acquires the patient's medical information and determines the corresponding safe threshold range based on this information and an average reference threshold. During the patient's daily use of the stoma abdominal binder, the system monitors the pressure in key areas in real time, obtaining the actual pressure parameters for each key area. After obtaining each actual pressure parameter, it is determined whether it falls within the safe threshold range. If the actual pressure parameter exceeds the safe threshold range, it is considered that the current pressure value poses an abnormal risk. In this case, several actual pressure parameters over a subsequent period are acquired, and the trend of these parameters over that period is used to determine whether to trigger an alarm. By adopting the above technical solution, significant individual differences among patients in terms of body shape, physical function, stoma type and location, and postoperative recovery stage are fully considered. By obtaining the initial pressure parameters after the patient first wears the abdominal binder and combining them with the patient's medical information, a personalized safety threshold range can be customized for each patient. Compared with the traditional uniform standard monitoring method, this personalized method can more accurately reflect the actual pressure tolerance and needs of each patient around the stoma, thereby achieving more precise pressure monitoring and management. During the patient's daily use of the stoma abdominal binder, the pressure in key areas is continuously monitored in real time. If the actual pressure parameters exceed the pre-set safety threshold range, the system immediately identifies the abnormal pressure value and quickly initiates subsequent analysis procedures. This real-time monitoring and timely judgment mechanism can detect problems in the early stages of pressure abnormalities, buying valuable time for timely intervention and effectively reducing the probability of complications such as parastomal hernia and local tissue damage caused by pressure abnormalities. For pressure exceeding the safety threshold, the analysis not only focuses on the current abnormal state but also acquires several actual pressure parameters over a period of time. By analyzing the trends in these parameters, it determines whether an alarm should be triggered and, if so, at what level. This trend-based analysis method is more scientific and accurate than simply relying on pressure values. For example, by calculating the rate of positive and negative pressure changes and determining the overall trend of pressure changes (increase, decrease, fluctuation, or stability), a more comprehensive understanding of the severity and development of the pressure abnormality can be obtained. This provides healthcare professionals and patients with more targeted early warning information, guiding them to take appropriate measures, such as timely adjustment of abdominal binder pressure and checking the stoma condition.

[0006] In one specific implementation scheme, the initial time period is a period after the patient has gradually adapted to the pressure of the abdominal binder and their condition has stabilized; the stoma perimeter is divided into several key areas, each key area corresponding to an initial pressure parameter; obtaining the average reference threshold based on all initial pressure parameters includes: Obtain the patient's BMI index; The average reference threshold is obtained based on the BMI index and all initial stress parameters.

[0007] By employing the aforementioned technical solution, the patient's BMI index is obtained, cleverly incorporating the key factor of patient body shape into the calculation of the average reference threshold. The BMI index indirectly reflects the thickness of abdominal fat, which is closely related to the body's tolerance to pressure. For example, obese patients (higher BMI values) typically have thicker abdominal fat, resulting in a relatively stronger ability to buffer pressure; while thin patients (lower BMI values) have relatively thinner abdominal muscles and fat, leading to poorer pressure tolerance. By considering the BMI index, this solution can more rationally adjust the average reference threshold for patients of different body types, making it more closely aligned with the individual patient's actual pressure tolerance. This provides a more accurate baseline standard for subsequent pressure monitoring. This comprehensive calculation method avoids the one-sidedness of determining the threshold based solely on a single factor, making the determination of the average reference threshold more scientific and comprehensive. It can more accurately reflect the pressure level experienced by the patient's stoma perimeter under normal conditions, providing a more reliable reference standard for subsequent assessment of whether the actual pressure is abnormal.

[0008] In one specific implementation scheme, the average reference threshold is calculated using the following formula: Δt = t - t0; f(Δt) = 1 + γ·Δt; Where α and β are constant values ​​derived from clinical data fitting, used to adjust the relationship between coefficient k and BIM; k is the adjustment coefficient related to BMI; P0 is the average reference threshold; N represents the total number of critical areas; W i The weighting parameter of the initial pressure parameter in the i-th critical region; P i The initial pressure parameter in the i-th critical region is represented by t0; the time of the first measurement of the pressure parameter is t0, and the current monitoring time is t; Δt represents the time interval; f(Δt) is a function that varies with time to describe the adjustment law of pressure with time; γ is a constant determined based on clinical experience and patient recovery, representing the rate of pressure change with time.

[0009] In a specific feasible implementation, determining whether to trigger an alarm based on the changing trend of the actual pressure parameters over that period includes: Acquire several actual pressure parameters over a period of time after an abnormal risk is detected in the current pressure value; The positive and negative rates of change of pressure over a period of time are obtained based on the actual pressure parameters. The formula for calculating the positive and negative rates of change is as follows: Where V0 represents the rate of change of the actual pressure parameter over a period of time; T 末 T represents the last actual pressure parameter acquired within a certain period of time. 初 t0 represents the first actual pressure parameter acquired within a certain period; t0 represents the duration of the period; the overall trend of pressure change is determined based on all actual pressure parameters within a certain period, and the target velocity is obtained based on the overall trend of pressure change and the positive and negative change rates; The target speed is compared with a preset first speed threshold and a preset second speed threshold to obtain the judgment result of the positive and negative speed changes; The alarm should be triggered based on the changes in actual pressure parameters during that period.

[0010] In a specific feasible implementation, the step of determining the overall trend of pressure change based on all actual pressure parameters over a period of time and obtaining the target velocity based on the overall trend of pressure change and the positive and negative change rates includes: If the actual pressure parameter continues to increase over a period of time, then the general trend of pressure change is upward. If the actual pressure parameter continues to decrease over a period of time, then the general trend of pressure change is downward. When the overall trend of pressure change is either increasing or decreasing, the current positive or negative rate of change is directly taken as the target rate. Otherwise, the pressure fluctuation judgment mechanism is triggered to obtain the overall trend of pressure change and the target speed is obtained based on the overall trend of pressure change and the positive and negative change rates; The target speed is compared with a preset first speed threshold and a preset second speed threshold to obtain the judgment result of the positive and negative speed changes; If the first actual pressure parameter acquired within a certain period is higher than the safety threshold range and the target speed is not negative, or if the first actual pressure parameter acquired within a certain period is lower than the safety threshold range and the target speed is not positive, then a Level 1 alarm is triggered when the change judgment result is relatively fast; a Level 2 alarm is triggered when the change judgment result is relatively slow; and a Level 3 alarm is triggered when the change judgment result is relatively stable.

[0011] In a specific feasible implementation, the triggering pressure fluctuation judgment mechanism to obtain the overall trend of pressure change and to obtain the target velocity based on the overall trend of pressure change and the positive and negative change rates includes: Input several actual pressure parameters over a period of time and their corresponding time points into a preset curve fitting algorithm model to obtain the fitted curve T(t). Calculate the average pressure of the fitted curve T(t) over a certain time interval. The formula for calculating the average pressure is: in, This represents the average pressure of the fitted curve T(t) in the interval [0, t0]. Calculate the sum of variances between all actual pressure parameters acquired over a period of time and the average pressure, and compare this sum of variances with a preset variance threshold to obtain the overall trend of pressure changes. The formula for calculating the sum of variances is: Among them, T i represents the i-th actual pressure parameter obtained within a certain period; N represents the total number of actual pressure parameters obtained within a certain period; D(t) represents the sum of variances between all actual pressure parameters and the average mixing pressure within a certain period; If the overall trend of pressure change is stable, then the positive and negative change rates are directly taken as the target rate.

[0012] In one specific implementation scheme, the pressure monitoring and early warning method further includes: After the patient has just put on the abdominal binder, the actual pressure and humidity levels at the stoma site, as well as the actual pressure values ​​of various key areas at the stoma site, are obtained. Determine whether the patient is currently suitable to wear an abdominal binder based on the actual pressure value, actual temperature, and humidity level.

[0013] By employing the aforementioned technical solution, the system can comprehensively determine whether a patient is suitable to wear an abdominal binder based on actual pressure, temperature, and humidity levels. By considering these different physiological indicators, the system can more accurately determine whether the abdominal binder is suitable for the current patient, improving the accuracy and scientific rigor of patient condition assessment. For example, excessively high or low pressure may affect the normal function of the stoma and the patient's comfort, while abnormal humidity levels may indicate problems such as stoma leakage, excessive local sweating, or dry and fragile skin. Through comprehensive judgment, adverse effects on the patient due to improper use of the abdominal binder can be avoided.

[0014] Secondly, this application provides a smart terminal, which adopts the following technical solution: A smart terminal is characterized by comprising a memory and a processor, wherein the memory stores at least one instruction, at least one program, code set, or instruction set, and the at least one instruction, at least one program, code set, or instruction set is loaded and executed by the processor to implement a stoma abdominal binder pressure monitoring method as described in the first aspect.

[0015] Thirdly, this application provides a stoma abdominal binder pressure monitoring system, which adopts the following technical solution: A stoma abdominal binder pressure monitoring system, comprising: The stoma abdominal binder provides protection and support for the patient's abdominal stoma, helping to reduce abdominal tension and promote wound healing. The data acquisition device includes a pressure detection unit and a physiological data acquisition unit. The pressure detection unit accurately measures the minute pressure values ​​around the stoma and sends the detected actual pressure values ​​to a smart terminal. The physiological data acquisition unit includes a pressure sensor and a humidity sensor. The pressure sensor monitors the actual pressure on the skin around the stoma in real time and sends the actual pressure to the smart terminal. The humidity sensor monitors the humidity level of the skin around the stoma in real time and sends the humidity level to the smart terminal. The intelligent terminal described in the second aspect is used to receive the actual pressure value emitted by the pressure detection unit and the actual pressure and humidity levels emitted by the physiological data acquisition unit, and to determine whether the patient is currently suitable to wear the stoma abdominal binder based on the actual pressure and humidity levels, and to determine whether to issue an early warning based on the actual pressure value to remind medical staff to readjust the pressure value of the abdominal binder on the patient's stoma site.

[0016] By adopting the above technical solution, this application has the following beneficial effects: I. Protective effect on stoma: ① Fixing the ostomy bag: When patients with enterostomy or urostomy move (such as walking, bending over, turning over, etc.), the ostomy bag is prone to shifting or falling off. The stoma abdominal binder of this application can help fix the ostomy bag by tightly fitting it to the body, reducing the risk of shaking and accidental fall off, thereby preventing leakage of excrement and causing infection of the stoma. ② Reduce pressure on the skin around the stoma: When the ostomy bag is directly attached to the skin, if the weight of the ostomy bag increases due to being filled with excrement, it may create a large pressure point on the skin around the stoma, leading to skin damage such as pressure sores. The stoma abdominal binder of this application reduces the possibility of local skin damage by evenly distributing the pressure over a larger area of ​​the abdomen, which helps to reduce the pressure of the stoma device on the skin and thus maintain the health of the skin around the stoma. ③Prevent external injury: In daily life, stoma patients may accidentally bump into objects, such as being bumped by others in crowded places, or being subjected to minor impacts during exercise. The stoma abdominal binder of this application can act as a protective shield, providing a certain physical protection for the stoma and reducing the occurrence of external forces directly acting on the stoma, thereby protecting the stoma and its surrounding tissues from damage. II. Supportive function for the body: ① Reducing abdominal pressure: For patients who have just undergone stoma surgery, their abdominal muscles and tissues may be relatively weak due to the surgical incision. The stoma abdominal binder of this application can provide certain support to the abdomen and reduce the increase in abdominal pressure caused by physical activity, coughing, laughing and other actions. For example, when patients cough after surgery, the abdominal binder can help reduce the stretching range of the abdominal muscles and reduce the risk of incision dehiscence and parastomal hernia formation. ② Promote physical recovery: The stoma abdominal binder of this application can promote local blood circulation in the skin by applying moderate pressure to the abdomen, reduce tissue edema, and help wound healing and tissue repair; ③ Improve body posture and mobility: Some patients may unconsciously hunch over due to abdominal discomfort after surgery. The stoma abdominal binder of this application can remind patients to straighten their backs to reduce the burden on their lower back. At the same time, this support can also enhance patients' confidence when moving, enabling them to perform simple exercises such as walking more freely, which is conducive to the recovery of physical function.

[0017] Fourthly, this application provides a computer-readable storage medium, which adopts the following technical solution: A computer-readable storage medium storing at least one instruction, at least one program, code set, or instruction set, wherein the at least one instruction, at least one program, code set, or instruction set is loaded and executed by a processor to implement a stoma abdominal binder pressure monitoring method as described in the first aspect.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. This application introduces an intelligent terminal for monitoring the pressure values ​​of key areas around the stoma, which solves the problem that existing stoma abdominal binders cannot directly and effectively treat the specific situation of the parastomal hernia after the patient inevitably develops a parastomal hernia due to factors such as lifestyle habits. This allows the abdominal binder to go beyond just basic fixation and limited support. Instead, it promotes the return of the hernia contents through dynamic pressure monitoring, adaptive safety threshold ranges for different patients, and manual adjustment of the pressure value to the safety threshold range, thus creating a favorable environment for the healing of the parastomal hernia. 2. This application can accurately monitor the pressure exerted by intra-abdominal organs on the outside of the abdomen based on the patient's individual physiological characteristics, such as abdominal contour, degree of obesity, and surgical-related factors (e.g., stoma location, surgical incision size, etc.). This helps medical staff to accurately locate abnormal areas based on the actual pressure values ​​of each key area, and enhances the ability to inhibit the outward protrusion of abdominal organs through the weak area next to the stoma. This greatly reduces the probability of treatment ineffectiveness or recurrence due to insufficient pressure, and improves the treatment effect.

[0019] 3. This application fully considers the individual differences of patients in terms of body shape, stoma type and location, and postoperative recovery stage. Through a series of steps (such as collecting initial pressure parameters, combining BMI index, and considering disease information), it determines the adaptive safe threshold range of various indicators, which changes the limitations of the traditional uniform standard and makes pressure monitoring more in line with the actual physical condition of each patient, thereby greatly improving the accuracy of using abdominal binders to treat parahernias. 4. When the actual pressure parameters exceed the safe threshold range, this application can accurately determine the speed and stability of pressure changes by further analyzing the rate and direction of pressure changes. It can also trigger corresponding alarm levels based on different situations, enabling medical staff and patients to promptly understand the urgency of the pressure abnormality and take targeted countermeasures. This effectively avoids serious complications such as parastomal hernia and local tissue damage caused by abnormal pressure, ensuring the patient's health and safety. 5. After the patient has just put on the abdominal binder, this application can comprehensively determine whether it is appropriate to continue wearing it based on multiple indicators such as the actual pressure value, temperature, duration of wear, and humidity level. This helps patients or medical staff to promptly identify situations where continued wear is not suitable, such as improper abdominal binder pressure settings or abnormal skin conditions at the stoma (uncomfortable humidity, abnormal temperature indicating inflammation or blood circulation problems, etc.). This avoids further harm to the patient from inappropriate wear and optimizes the entire stoma care process. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the structure of a stoma abdominal binder pressure monitoring system according to an embodiment of this application.

[0021] Figure 2 This is a schematic flowchart of a stoma abdominal binder pressure monitoring method according to another embodiment of this application. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0023] The following describes in further detail, with reference to the accompanying drawings, an embodiment of a stoma abdominal binder pressure monitoring method, system, device, and medium of this application.

[0024] One embodiment of this application discloses a stoma abdominal binder pressure monitoring system.

[0025] Reference Figure 1A stoma abdominal binder pressure monitoring system includes a stoma abdominal binder, data acquisition devices, and a smart terminal. The data acquisition devices are evenly and closely arranged on the stoma abdominal binder according to the shape and size of the stoma, and these devices can fully cover the skin area surrounding the stoma. For example, for a circular stoma, the data acquisition devices can be distributed in a ring around the corresponding position on the abdominal binder; for an elliptical stoma, the pressure monitoring devices can be arranged along the extensions of its major and minor axes to ensure accurate measurement of the pressure on different areas around the patient's stoma. The data acquisition device in this embodiment includes a pressure detection unit and a physiological data acquisition unit. The pressure detection unit takes a high-precision and high-sensitivity pressure sensor, such as a thin-film pressure sensor, as an example. The pressure detection unit is used to accurately measure the minute pressure value around the stoma and send the detected actual pressure value to the smart terminal. The physiological data acquisition unit integrates a variety of advanced sensors, including a pressure sensor and a humidity sensor, which can comprehensively collect physiological information closely related to the patient's health. Among them, the pressure sensor is used to monitor the actual pressure of the skin around the stoma in real time and send the actual pressure to the smart terminal; the humidity sensor is used to monitor the humidity level of the skin around the stoma in real time and send the humidity level to the smart terminal.

[0026] Considering that inflammatory reactions at the stoma site are often accompanied by increased local pressure, continuous pressure monitoring helps to detect potential infection risks in a timely manner. At the same time, leakage of stoma discharge or sweating of the local skin can lead to changes in humidity. If the humidity is too high, it may cause skin maceration, damage, and other problems, affecting stoma care and healing. Therefore, the stoma abdominal binder in this application uses corresponding pressure sensors / humidity sensors to monitor the temperature and humidity of the skin around the stoma in a comprehensive and real-time manner, so as to accurately sense the pressure from the abdominal organs on different parts of the abdominal binder.

[0027] The intelligent terminal receives the actual pressure value from the pressure detection unit and the actual pressure and humidity levels from the physiological data acquisition unit. Based on the actual pressure and humidity levels, it determines whether the patient is currently suitable to wear a stoma abdominal binder. It also determines whether to issue an alert based on the actual pressure value to remind medical staff to readjust the pressure of the abdominal binder on the patient's stoma site. The intelligent terminal includes a processor and a memory, which stores at least one instruction, at least one program, code set, or instruction set. When the processor executes at least one instruction, at least one program, code set, or instruction set, it performs the following steps.

[0028] It should be noted that the stoma abdominal binder mentioned in this embodiment is mainly used in two stages: On the one hand, after the abdominal wound caused by the stoma surgery has initially healed and the patient wears the stoma abdominal binder, the stoma abdominal binder in this embodiment, with its built-in high-precision pressure sensor, can monitor the pressure in different areas around the stoma in real time and transmit the data to the connected smart terminal. When the smart terminal analyzes and determines that the pressure in a certain key area is insufficient or exceeds the appropriate range, it will promptly issue an alarm to the patient. After receiving the alarm, the patient needs to manually adjust the pressure value of the abdominal binder on that key area by increasing (decreasing) the pressure on that key area. The methods include: (1) A flexible, movable thickened pad is used. When the alarm indicates insufficient pressure, the patient slides the thickened pad along the circular track of the abdominal binder to a specific critical area to increase pressure support for that critical area. Conversely, the thickened pad is moved in the opposite direction to distribute the pressure to the surrounding area. (2) An adjustment buckle is set around the stoma of the abdominal binder. The side wall of the adjustment buckle is provided with several elastic bags corresponding to each key area. Each elastic bag and the outer surface of the abdominal binder form a slot. Pressure adjustment inserts of different thicknesses can be inserted into the slot. In the default state, the inner side wall of the elastic bag is close to the outer side wall of the abdominal binder (that is, when inserting the pressure adjustment insert, the elastic bag needs to be opened first. After the insert is inserted, the elastic bag will close again under its own retraction pressure. However, since there is one more insert in the slot than before, the pressure on the key area corresponding to the elastic bag will increase. When the smart terminal reports that the pressure of a key area is lower than the appropriate range for preventing parastomal hernia, the patient can insert a pressure adjustment insert into the corresponding slot to increase the overall tightness of the abdominal binder, thereby indirectly increasing the pressure on the key area. Conversely, the corresponding pressure adjustment insert is removed to loosen the abdominal binder, thereby reducing the pressure on the key area. Through this combination of real-time automatic warning and manual adjustment, the stoma abdominal binder of this embodiment can effectively enhance the prevention effect of parastomal hernia through simple operation. The thickened pads / pressure adjustment inserts in (1) and (2) above are all made of soft and supportive materials, such as memory foam. These materials have good plasticity and resilience, which can not only adjust the abdominal belt pressure more accurately, but also avoid causing local hard compression on the patient's abdomen due to their softness. They can relieve local tissue compression to a certain extent, promote blood circulation, and help improve the discomfort symptoms caused by the presence of hernia sac. On the other hand, in the early stage of parastomal hernia, patients can still wear the stoma abdominal binder of this embodiment. At this time, the pressure detection unit of the stoma abdominal binder is used to continuously monitor the pressure changes of the protruding part of the hernia sac and the surrounding area (i.e., some key areas), and to provide feedback on abnormal pressure to the patient through the smart terminal. Based on these warning information, the patient can take corresponding measures (the specific methods are the same as those in (1) and (2) above). Therefore, the stoma abdominal binder of this embodiment, through precise pressure monitoring of key areas, helps patients adjust the pressure value of key areas in a timely manner according to the actual pressure situation, so as to effectively and appropriately inhibit the protruding part of the hernia sac, help maintain the relative stability of the hernia sac, avoid the rapid deterioration of the condition due to pressure fluctuations and other factors, thereby slowing down the progression of the disease, and to a certain extent, can help the hernia sac retract slowly and improve parahernia symptoms. In summary, compared with traditional stoma abdominal binders, the stoma abdominal binder of this embodiment has several advantages in preventing parastomal hernias. It utilizes a data acquisition device for real-time monitoring and early warning, guiding patients to adjust pressure in key areas promptly and effectively. This overcomes the limitations of traditional abdominal binders, which suffer from uneven pressure distribution and lack of real-time feedback, providing a relatively stable and suitable pressure environment for the critical areas around the stoma and greatly enhancing the preventative effect. Regarding the treatment of parastomal hernias, the stoma abdominal binder of this embodiment can still be used in the early stages of treatment after the onset of a parastomal hernia. It can fully utilize its role in assisting the treatment of parastomal hernias by helping patients adjust the pressure at the protruding part of the hernia sac, significantly enhancing the practicality of the stoma abdominal binder.

[0029] The implementation of the method will be explained in detail below with reference to the above system: Reference Figure 2 Another embodiment of this application provides a method for monitoring stoma abdominal binder pressure, including: Considering the significant individual differences among patients in terms of body shape, physical function, stoma type and location, and postoperative recovery stage—meaning that each patient has different key indicators such as the appropriate pressure around the stoma and the skin's temperature and humidity tolerance range under normal physiological conditions—it is difficult to measure and define them using a uniform standard. Therefore, the following steps are used to determine the adaptive threshold ranges for each indicator: S100 measures the initial pressure parameters of each key area around the stoma during the initial period after the patient has worn the stoma abdominal binder for the first time. The initial wearing of a stoma abdominal binder is typically determined by medical staff based on the stoma's healing progress, skin condition, and overall recovery. This period generally coincides with the initial healing phase of the post-stomach wound, during which there should be no significant exudation, redness, or other abnormalities. Once medical staff confirm that the patient is suitable for initial wear of the abdominal binder, the patient should be guided to maintain a comfortable and relatively still state, such as lying quietly on an examination bed or sitting quietly in a comfortable chair. The initial period refers to the time after the patient gradually adapts to the pressure of the binder and their condition stabilizes. In this embodiment, the period is 3 consecutive hours after the patient has worn the binder for 10 minutes. In this embodiment, the area around the stoma is divided into several key regions. This embodiment uses 8 regions as an example: directly above the stoma, directly below the stoma, to the left, to the right, radiating 45 degrees upwards from the stoma, and radiating 45 degrees downwards from the stoma. The initial pressure parameters correspond one-to-one with each key region.

[0030] S200, the average reference threshold is obtained based on all initial pressure parameters; The average reference threshold is used as a standard pressure indicator for subsequent pressure monitoring, to help determine whether there are abnormalities in the pressure exerted by intra-abdominal organs at the stoma site on each key area; specifically, S200 includes: S210, obtain the patient's BMI index; In this embodiment, considering the influence of factors such as patient body shape and physical function on stress tolerance, the BMI index is used to indirectly reflect the relationship between the patient's abdominal fat thickness and the body's tolerance to pressure. S220, based on the BMI index and all initial pressure parameters, yields an average reference threshold; The formula for calculating the average reference threshold is as follows: Δt = t - t0; f(Δt) = 1 + γ·Δt; Here, α and β are constant values ​​derived from clinical data fitting, used to adjust the relationship between coefficient k and BMI. Generally, β can be taken as the median value of the normal BMI range, while α can be determined through regression analysis of a large number of patients' pressure tolerance experimental data. k is an adjustment coefficient related to BMI. When a patient's BMI value deviates significantly from the normal range, the k value will be adjusted accordingly to increase the average reference threshold. For example, obese patients (higher BMI values) have thicker abdominal fat, which may provide stronger pressure buffering capacity, so the k value will be appropriately increased, thereby raising the average reference threshold. Conversely, thin patients (lower BMI values) have relatively thin abdominal muscles and fat, so the k value will be decreased to lower the average reference threshold, better adapting to the patient's physical condition. P0 is the average reference threshold; N represents the total number of critical areas; W i The weighting parameter of the initial pressure parameter in the i-th critical region; P i Let represent the initial pressure parameter in the i-th critical region; the time of the first measurement of the pressure parameter is t0, and the current monitoring time is t; Δt represents the time interval; f(Δt) is a function that varies with time to describe the adjustment law of pressure over time. As time goes by, the patient's body gradually adapts to the abdominal binder pressure, which may require appropriate adjustment of the average reference threshold. For example, in the early postoperative period, the patient's body is more sensitive, and the average reference threshold is lower; as the recovery time increases, the body's adaptability increases, and the average reference threshold is appropriately increased through the f(Δt) function to ensure that the abdominal binder pressure is always within an appropriate range; γ is a constant determined based on clinical experience and the patient's recovery, representing the rate of pressure change over time.

[0031] S300: Obtain the patient's disease information and determine the safe threshold range corresponding to the patient based on the disease information and the average reference threshold. The medical information includes other underlying conditions besides stoma-related diseases, such as hypertension, diabetes, and cardiovascular disease. These conditions significantly impact a patient's physical condition and stress tolerance. For example, hypertensive patients experience greater pressure on their blood vessel walls, and excessive abdominal binder pressure may increase the burden on the cardiovascular system; therefore, the upper limit of the safe threshold range should be appropriately lowered. Diabetic patients have poor skin healing ability and relatively low stress tolerance, so the safe threshold range should be set more cautiously. Simultaneously, stoma-related medical information should be considered, such as the cause of the stoma and the presence of complications such as stoma stenosis or retraction. If the stoma is caused by a tumor and the surrounding tissues are fragile, the safe threshold range needs to be strictly controlled to avoid excessive pressure on the tumor site. If stoma stenosis exists, the lower limit of the pressure threshold should be appropriately lowered to prevent excessive pressure from worsening the stenosis. Based on the average reference threshold and the above medical information, adjustments should be made. For patients with poor physical condition and high disease risk, the safe threshold range should be appropriately narrowed to ensure patient safety. For patients with relatively good physical condition and less impact from their disease, the safe threshold range can be appropriately expanded within a reasonable range to improve patient comfort.

[0032] The S400 monitors the pressure in key areas in real time during the patient's daily use of the stoma abdominal binder, obtains the actual pressure parameters corresponding to each key area, and determines whether each actual pressure parameter is within the safe threshold range.

[0033] S500: If the actual pressure parameter exceeds the safety threshold range, it is considered that the current pressure value has an abnormal risk. At this time, several actual pressure parameters are obtained in the following period, and the alarm is triggered based on the changing trend of the actual pressure parameter in that period. Specifically, the steps taken by the S500 after detecting an abnormal risk in the current pressure value include: S510: Obtain several actual pressure parameters within a certain period of time after detecting an abnormal risk in the current pressure value; In this embodiment, a period of time is taken as ten minutes. The acquired actual pressure parameters correspond one-to-one with several time points within a period of time. This embodiment takes the acquisition of five actual pressure parameters at five different time points within ten minutes as an example.

[0034] S520, based on actual pressure parameters, obtains its positive and negative rate of change over a period of time; The positive and negative values ​​of the rate of change represent the direction of change of the actual pressure parameter over a period of time; positive values ​​represent an increase, and negative values ​​represent a decrease. The formula for calculating the rate of change is: Where V0 represents the rate of change of the actual pressure parameter over a period of time; T末 T represents the last actual pressure parameter acquired within a certain period of time. 初 t0 represents the first actual pressure parameter acquired within a certain period of time; t0 represents the duration of that period of time.

[0035] S530 determines the overall trend of pressure change based on all actual pressure parameters over a period of time and obtains the target speed based on the overall trend of pressure change and the positive and negative change rates. The general trend of pressure changes includes fluctuation, increase, decrease, and stabilization. Specifically, S530 includes the following steps S531-S533: S531, if the actual pressure parameter continuously increases over a period of time, the general trend of pressure change is increasing; if the actual pressure parameter continuously decreases over a period of time, the general trend of pressure change is decreasing. S532, when the overall trend of pressure change is increasing or decreasing, the positive and negative change rates in S520 are directly used as the target rate; S533, otherwise, the pressure fluctuation judgment mechanism is triggered to obtain the overall trend of pressure change and the target rate is obtained based on the overall trend of pressure change and the positive and negative change rates. The general trend of pressure changes includes fluctuations and stability; S533 specifically includes: S5331, input several actual pressure parameters over a period of time and their corresponding time points into a preset curve fitting algorithm model to obtain the fitted curve T(t). The fitted curve T(t) reflects the trend of the actual pressure parameter over a period of time. The curve fitting algorithm model adopts the least squares method, and its calculation formula is as follows: T = a + bt; Where a and b are coefficients of the fitted curve T(t); T represents the actual pressure parameter at each time point on the fitted curve T(t); t represents the actual pressure parameter at each time point obtained within a period of time; and n represents the nth actual pressure parameter obtained within a period of time and its corresponding time point.

[0036] S5332, calculate the average pressure of the fitted curve T(t) over a time interval; The average pressure is the average of all actual pressure parameters continuously applied to the fitted curve T(t) over a period of time; the formula for calculating this average pressure is: in, This represents the average pressure of the fitted curve T(t) in the interval [0, t0].

[0037] S5333, calculate the sum of variances between all actual pressure parameters and average pressure acquired over a period of time, and compare the sum of variances with a preset variance threshold to obtain the overall trend of pressure change; Specifically, if the sum of variances is greater than the variance sum threshold, the overall trend of pressure change is fluctuating; if the sum of variances is less than or equal to the variance sum threshold, the overall trend of pressure change is stable; in this embodiment, the variance sum threshold is taken as 1; the formula for calculating the sum of variances is: Among them, T i denoted as the i-th actual pressure parameter obtained within a certain period; N represents the total number of actual pressure parameters obtained within a certain period; D(t) represents the sum of variances between all actual pressure parameters and the average mixing pressure within a certain period.

[0038] S5334 If the overall trend of pressure change is stable, then the positive and negative change rates in S520 are directly used as the target rate.

[0039] S5335, if the overall trend of pressure change is fluctuating, then the offset velocity is obtained based on several actual pressure parameters over a period of time, and the offset velocity is substituted into a preset objective function formula to obtain the target velocity; The offset velocity is calculated from the fitted curve T(t) obtained based on several actual pressure parameters over a period of time, and its calculation formula is as follows: in, V represents the average pressure of the fitted curve T(t) in the interval [0, t0]; 偏移 This indicates the rate of change of the actual pressure parameter over a period of time. The objective function formula in S5335 is as follows: V0′=cV0+dV 偏移 ; c+d=1; Where V0′ represents the target velocity; c represents the weighting parameter of V0; and d represents the weighting parameter of V0. 偏移 The weighting parameters are: in this example, c is 0.7 and d is 0.3.

[0040] S540, compare the target speed with a preset first speed threshold and a preset second speed threshold to obtain the judgment result of the positive and negative speed changes; The first speed threshold is greater than the second speed threshold, and the change judgment result includes faster, slower, and more stable. In this embodiment, the first speed threshold is 3 mmHg / h, and the second speed threshold is 2 mmHg / h.

[0041] Specifically, the S540 includes: S541, If ​​the target speed obtained in S530 is greater than or equal to the first speed threshold, the change judgment result is relatively fast; S542, If the target speed obtained in S530 is less than the first speed threshold and greater than the second speed threshold, the change judgment result is slow. S543, if the target speed obtained in S530 is less than or equal to the second speed threshold, the change judgment result is relatively stable.

[0042] S550: If the first actual pressure parameter acquired within a certain period of time is higher than the safety threshold range and the target speed is not negative, or if the first actual pressure parameter acquired within a certain period of time is lower than the safety threshold range and the target speed is not positive, then when the change judgment result is relatively fast, a level 1 alarm is triggered; when the change judgment result is relatively slow, a level 2 alarm is triggered; when the change judgment result is relatively stable, a level 3 alarm is triggered. Among them, a positive target speed indicates that the actual pressure parameter increases over a period of time, a negative target speed indicates that the actual pressure parameter decreases over a period of time, and a target speed that is neither positive nor negative indicates that the actual pressure parameter remains unchanged over a period of time. Once an alarm is triggered, the smart terminal will immediately send a warning notification to medical staff and patients. The notification methods include, but are not limited to, sound alarms, vibration alerts, pop-up reminders, and SMS push notifications. For Level 1 alarms, the message should emphasize the urgency of the situation, requiring immediate checking of the abdominal binder application and the patient's condition, potentially necessitating emergency intervention from medical staff. For example, a voice prompt could state, "Level 1 Alarm! Abnormally rapid pressure changes in critical stoma areas pose a serious risk; please take immediate action." For Level 2 alarms, inform medical staff and the patient of the potential risk associated with the pressure changes and recommend prompt review and assessment, such as, "Level 2 Alarm! Stoma pressure changes slowly but exceeds the safe range; close monitoring is required." For Level 3 alarms, remind the patient that the pressure is unstable and requires continuous observation, such as, "Level 3 Alarm! Stoma pressure is relatively stable but still deviates from the safe range; please be cautious."

[0043] It is important to note that upon receiving an alarm, medical staff should take appropriate action based on the alarm level: For a Level 1 alarm, they should promptly go to the patient's location to check if the abdominal binder is too tight or misaligned, and observe the patient for any discomfort symptoms such as abdominal pain or skin redness. If a problem with the abdominal binder is found, its tightness should be adjusted promptly. If the patient experiences discomfort, the stoma and surrounding tissues should be further examined, and relevant medical treatment should be provided if necessary. For a Level 2 alarm, communication can be conducted with the patient via telephone or video, instructing them to check the abdominal binder themselves and inquiring about any abnormal sensations. If the patient cannot resolve the issue independently, a follow-up appointment or home visit should be arranged as soon as possible. For a Level 3 alarm, the patient is advised to closely monitor their condition and record changes in pressure data. Medical staff should increase the frequency of monitoring for this patient in subsequent work.

[0044] In addition, since patients are not suitable to continue wearing abdominal binders in some cases, the stoma abdominal binder pressure monitoring method in this embodiment also includes the following steps: The S600, after the patient has just put on the abdominal binder, acquires the actual pressure and humidity level at the stoma through the physiological data acquisition unit, and acquires the actual pressure values ​​of various key areas at the stoma through the pressure acquisition unit.

[0045] The S700 determines whether a patient is suitable to wear an abdominal binder based on actual pressure, temperature, and humidity levels. The smart terminal has pre-stored normal reference temperature and humidity for the skin at the stoma site. Specifically, the smart terminal first compares the collected actual pressure value with a safe threshold range. If the actual pressure value is not within the safe threshold range, it indicates that the abdominal binder pressure may cause excessive pressure or insufficient support to the stoma, increasing the risk of local tissue damage or parastomal hernia. In this case, it is determined that the pressure value setting is incorrect and the patient is not suitable to wear the binder, and it needs to be readjusted. Regarding humidity levels, excessively high humidity, such as exceeding the upper limit of normal skin humidity, may indicate stoma leakage or excessive local sweating, which can easily lead to skin maceration and damage. If the humidity is too low, it may cause dry and fragile skin, which is also not conducive to stoma care. At the same time, if the skin temperature around the stoma is significantly higher than normal body temperature, there may be a risk of inflammation or infection, and continuing to wear an abdominal binder may worsen the symptoms. If the temperature is too low, it may affect local blood circulation. When one or both of the above two indicators (temperature / humidity) are abnormal, it is determined that the skin condition at the stoma is abnormal and it is not suitable to wear the binder.

[0046] In addition, it should be noted that the smart terminal in this embodiment can also start calculating the wearing time after the pressure value is not 0, and issue a reminder when the patient wears the device for too long. Specifically, the smart terminal has a pre-set database of reasonable wearing time standards for different patient conditions and the purpose of using the abdominal binder. This database is based on a large amount of clinical data and research. When the pressure sensor detects that the pressure applied by the abdominal binder to the stoma is not zero, it determines that the abdominal binder is being worn. At this time, the timing module of the smart terminal begins to accurately time and record the time the patient wears the abdominal binder in real time. During the timing process, the smart terminal continuously compares the current wearing time with the preset reasonable time standard. Once the wearing time reaches or exceeds the corresponding standard value, the smart terminal will issue reminders in various ways, such as sound alarms, vibration prompts, and prominent prompts on the display screen, informing the patient that they need to adjust the use of the abdominal binder in time, such as temporarily removing the abdominal binder for appropriate rest, to avoid skin damage, poor blood circulation and other problems that may be caused by wearing the abdominal binder for a long time. This ensures the safety and comfort of the patient when using the abdominal binder, and also helps to improve the effectiveness of the abdominal binder, better promote the patient's recovery and prevent related complications.
