Description

Technical Field

[0001] This application relates to the technical field of scar prevention, and particularly relates to a wound pressure monitoring method, system, device and medium for preventing scars. Background Art

[0002] Scar is a general term for the appearance and histopathological changes of normal skin tissue caused by various traumas, and it is an inevitable product in the process of human wound repair. When scar growth exceeds a certain limit, various complications will occur, such as the destruction of appearance and the disorder of functional activities, bringing great physical and mental pain to patients, especially the scars left after burns, scalds and severe trauma. Scars have many adverse effects on people. For example, scars may cause uneven skin surface, pigmentation or depigmentation, thus affecting the appearance and bringing psychological burden to patients, especially the scars on exposed parts such as the face. At the same time, scars will make people have discomfort symptoms such as itching and pain, seriously affecting the quality of life. Therefore, how to prevent the scars on the wound surface of people and reduce the risk of people getting scars is an urgent problem to be solved.

[0003] Currently, the commonly used method for scar prevention in people is to monitor the discomfort symptoms such as itching and pain of people and the condition of the wound surface in real time. Once an abnormality is found, external pressure treatment is carried out in time to achieve scar prevention. However, once an abnormality is found in this way, the scar has usually initially formed, and the intervention carried out is the intervention after the scar appears, resulting in a poor prevention effect on the scar at the wound surface. Summary of the Invention

[0004] To improve the prevention effect of scars at the wound surface, this application provides a wound pressure monitoring method, system, device and medium for preventing scars.

[0005] In the first aspect of this application, a wound pressure monitoring method for preventing scars is provided, which specifically includes:

[0006] Obtain the target group type of the target patient, and obtain the target wound type of the wound that the target patient has;

[0007] When the negative pressure drainage of the target patient has not ended, based on at least one target negative pressure and the corresponding at least one target duration range during the negative pressure drainage of historical patients, determine whether to adjust the current negative pressure in the negative pressure drainage of the target patient; the historical patients are patients with the target group type and having the target wound type, the target negative pressure is the negative pressure that is easy to set for negative pressure drainage, and the target duration range is the duration range in which the negative pressure duration of the target negative pressure is easy to be when scars appear at the wound surface;

[0008] If so, determine the appropriate negative pressure that matches the target patient, and continue the negative pressure drainage for the target patient based on the appropriate negative pressure;

[0009] At the end of the negative pressure drainage for the target patient, determine the appropriate interval duration for starting the pressure application for scar prevention for the target patient based on at least one actual negative pressure and the corresponding actual duration in the negative pressure drainage of the target patient;

[0010] Determine the appropriate applied pressure for the pressure application for scar prevention for the target patient, and perform the pressure application for scar prevention for the target patient according to the appropriate interval duration and the appropriate applied pressure.

[0011] By adopting the above technical solution, after obtaining the target group type and the target wound surface type, based on the target negative pressure of historical patients and the corresponding target duration range, analyze the likelihood of the current negative pressure during the negative pressure drainage of the target patient inducing scars in the future, and then determine whether to adjust the current negative pressure. If it is determined that adjustment is needed, then determine the appropriate negative pressure and continue the drainage with the appropriate negative pressure, so as to achieve the prevention of scars during the negative pressure drainage stage. Further, at the end of the negative pressure drainage, based on the actual negative pressure and the corresponding actual duration, analyze the optimal timing for performing the pressure application for scar prevention, so as to determine the appropriate interval duration. Finally, according to the appropriate interval duration and the appropriate applied pressure, perform the pressure application for scar prevention on the wound surface of the target patient at a reasonable timing and external pressure, so as to better improve the prevention effect of scars at the wound surface.

[0012] Optionally, the determining whether to adjust the current negative pressure in the negative pressure drainage of the target patient based on at least one target negative pressure and the corresponding at least one target duration range during the negative pressure drainage of historical patients specifically includes:

[0013] Obtain the historical negative pressure in the negative pressure drainage performed by historical patients, count the first occurrence times of each historical negative pressure, and select the first number of historical negative pressures from each historical negative pressure in descending order of the first occurrence times as the target negative pressure;

[0014] Obtain the historical duration range in which the duration of a single target negative pressure is located on the premise that scars appear on the wound surface of historical patients, count the second occurrence times of each historical duration range, and select the second number of historical duration ranges from each historical duration range in descending order of the second occurrence times as the target duration range, where the target duration range is the historical duration range corresponding to a single target negative pressure;

[0015] Determine the first weight of each of the target negative pressures, and determine the second weight of each of the target duration ranges corresponding to each of the target negative pressures. The first weight is the ratio of the first occurrence times of each target negative pressure to the sum of the first occurrence times of all target negative pressures, and the second weight is the ratio of the second occurrence times of a single target duration range corresponding to a target negative pressure to the sum of the second occurrence times of all the target duration ranges corresponding thereto;

[0016] Obtain the current negative pressure and the corresponding current duration in the negative pressure drainage of the target patient, and determine whether to adjust the current negative pressure in the negative pressure drainage of the target patient based on the current negative pressure, the current duration, the first weight, and the corresponding second weights.

[0017] By adopting the above technical solution, the larger the first occurrence times, the easier it is for the historical patient to set the corresponding historical negative pressure for the wound surface during negative pressure drainage, and then determine the target negative pressure; the larger the second occurrence times, during the negative pressure drainage process, when the duration of the target negative pressure is within the corresponding historical duration range, it is more likely to have scars after the subsequent wound healing. Finally, combining the first weight and the corresponding second weights, analyze the current negative pressure at the current duration, and induce the possibility of subsequent scar formation. Then, based on the consideration of scar prevention, more accurately determine whether to adjust the current negative pressure in the negative pressure drainage of the target patient.

[0018] Optionally, the determining whether to adjust the current negative pressure in the negative pressure drainage of the target patient based on the current negative pressure, the current duration, the first weight, and the corresponding second weights specifically includes:

[0019] When the current negative pressure is the target negative pressure, if the current duration is within the target duration range corresponding to the current negative pressure, then determine the corresponding target duration range as the first duration range;

[0020] Calculate the first product of the first weight of the current negative pressure and the second weight of the corresponding first duration range. If the first product is greater than a preset first threshold, then determine to adjust the current negative pressure;

[0021] When the current negative pressure is not the target negative pressure, determine the target negative pressure greater than the current negative pressure as the first negative pressure, determine the target negative pressure less than the current negative pressure as the second negative pressure, and determine the target duration range in which the current duration is located as the second duration range;

[0022] Calculate the second product of the first weight of the first negative pressure and the second weight of the corresponding second duration range, and calculate the third product of the first weight of the second negative pressure and the second weight of the corresponding second duration range;

[0023] When both the second product and the third product are greater than the first threshold, it is determined to adjust the current negative pressure.

[0024] By adopting the above technical solution, the larger the first product, the greater the risk of scar formation at the subsequent wound surface under the current negative pressure with the current duration in the negative pressure drainage of the target patient. If the first product is greater than the preset first threshold, it indicates that if the negative pressure drainage continues at this current negative pressure, the risk of scar formation at the subsequent wound surface is relatively high. Then, it is determined to adjust this current negative pressure, so as to prevent scars in advance during the negative pressure drainage stage. If both the second product and the third product are greater than the first threshold, it means that whether the negative pressure is greater than the current negative pressure or less than the current negative pressure, the risk of scar formation at the subsequent wound surface will be relatively high under the current duration. This further indicates that the current negative pressure needs to be adjusted.

[0025] Optionally, the determination of the appropriate negative pressure matching the target patient specifically includes:

[0026] Determine the remaining drainage duration of the negative pressure drainage of the target patient;

[0027] If the remaining drainage duration exists in the target duration range corresponding to the target negative pressure, the corresponding target negative pressure is determined as the key negative pressure, and the target duration range where the remaining drainage duration exists is determined as the key duration range;

[0028] Calculate the fourth product of the first weight of each key negative pressure and the second weight of the corresponding key duration range, and select the minimum fourth product from each of the fourth products;

[0029] Determine the appropriate negative pressure matching the target patient as the key negative pressure corresponding to the minimum fourth product.

[0030] By adopting the above technical solution, the smaller the fourth product, the smaller the possibility of scar formation at the subsequent wound surface when the key negative pressure corresponding to the negative pressure drainage lasts for this remaining drainage duration. Then, the minimum fourth product is selected from each of the fourth products, and the key negative pressure corresponding to the minimum fourth product is determined as the appropriate negative pressure matching the target patient. Finally, the current negative pressure is adjusted to this appropriate negative pressure through the negative pressure drainage device, and the wound surface of the target patient is continuously subjected to negative pressure drainage with this appropriate negative pressure, which can not only optimize the effect of negative pressure drainage, but also play a better role in preventing subsequent scars.

[0031] Optionally, the determination of the appropriate interval duration for starting the pressure application to prevent scars based on at least one actual negative pressure and the corresponding actual duration in the negative pressure drainage of the target patient specifically includes:

[0032] If the actual negative pressure in the negative pressure drainage of the target patient is the target negative pressure, the corresponding actual negative pressure is determined as the important negative pressure, and when the actual duration of the important negative pressure is within the corresponding target duration range, the corresponding target duration range is determined as the important duration range;

[0033] Calculate the fifth product of the first weight of each important negative pressure and the second weight of the corresponding important duration range, and sum up the fifth products to obtain the corresponding sum of the first products;

[0034] According to the sum of the first products, determine the appropriate interval duration between the pressure application for scar prevention and the end of negative pressure drainage. The larger the sum of the first products, the smaller the appropriate interval duration.

[0035] By adopting the above technical solution, the larger the sum of the first products, the greater the possibility of increasing the risk of scar appearance during the entire negative pressure drainage stage, and the more necessary it is to prevent scars earlier after the end of negative pressure drainage. Then the appropriate interval duration is smaller, so that the pressure application for scar prevention has a better preventive effect on the scars at the wound surface.

[0036] Optionally, the determination of the appropriate applied pressure when performing pressure application for scar prevention on the target patient specifically includes:

[0037] Obtain the interval duration when the historical patients without scars start pressure application for scar prevention, and count the first occurrence frequencies of at least one historical duration range where the interval duration is located. Then, in the order from largest to smallest of the first occurrence frequencies, select the third number of historical duration ranges from each historical duration range and determine them as the target duration ranges; the interval duration is the duration between the end time of negative pressure drainage and the start time of pressure application for scar prevention;

[0038] Obtain the historical pressures applied when the historical patients without scars perform pressure application for scar prevention under a single target duration range, count the second occurrence frequencies of each historical pressure, and in the order from largest to smallest of the second occurrence frequencies, select the fourth number of historical pressures from each historical pressure and determine them as the target pressures for the corresponding target duration ranges;

[0039] Determine the third weight of each target duration range and the fourth weight of each target pressure corresponding to each target duration range. The third weight is the ratio of the first occurrence frequency of each target duration range to the sum of the first occurrence frequencies of all target duration ranges, and the fourth weight is the ratio of the second occurrence frequency of a single target pressure corresponding to the target duration range to the sum of the second occurrence frequencies of all target pressures corresponding to the target duration range;

[0040] Determine the appropriate applied pressure for scar prevention by compression on the target patient according to the third weight and the corresponding fourth weights.

[0041] By adopting the above technical solution, the greater the first occurrence frequency, the smaller the possibility of scarring when the interval duration is within the corresponding historical duration range, and then the target duration range is determined; the greater the second occurrence frequency, the smaller the possibility of scarring when the interval duration is within a single target duration range and the corresponding historical pressure is externally applied for scar prevention, and then the target pressure is determined. Finally, in combination with the third weight and the corresponding fourth weights, the appropriate applied pressure with a relatively small possibility of scarring is accurately analyzed and determined.

[0042] Optionally, the determining the appropriate applied pressure for scar prevention by compression on the target patient according to the third weight and the corresponding fourth weights specifically includes:

[0043] Calculate the sixth product of the third weight of each target duration range and the corresponding fourth weights of the target pressures, and sum up the sixth products to obtain the sum of the second products corresponding to the target duration range.

[0044] Determine the target duration range where the appropriate interval duration is located as the final duration range. If the sum of the second products corresponding to the final duration range is greater than a preset second threshold, it is determined that the rationality verification of the appropriate interval duration passes.

[0045] After the rationality verification of the appropriate interval duration passes, determine the target pressures corresponding to the final duration range as the candidate pressures, and sum up all the sixth products corresponding to the same candidate pressure to obtain the sum of the third products.

[0046] Select the maximum sum of the third products from the sums of the third products, and determine the candidate pressure corresponding to the maximum sum of the third products as the appropriate applied pressure for scar prevention by compression on the target patient.

[0047] By adopting the above technical solution, if the sum of the second products corresponding to the final duration range is greater than the preset second threshold, it indicates that when the interval duration is within this final duration range, the possibility of subsequent scarring is smaller, indicating that the preventive effect of scar prevention by compression is better after an appropriate interval duration at the end of negative pressure drainage. Then it is determined that this appropriate interval duration is relatively reasonable, that is, the rationality verification passes, thus making the timing of scar prevention by compression more reasonable. The greater the sum of the third products, the smaller the overall possibility of subsequent scarring when scar prevention is carried out with this candidate pressure, indicating that the scar prevention effect of this candidate pressure is better, and then the appropriate applied pressure is determined.

[0048] In the second aspect of the present application, a wound pressure monitoring system for preventing scars is provided, specifically including:

[0049] An information acquisition module, configured to acquire the target group type of the target patient and the target wound type of the wound the target patient has;

[0050] An adjustment determination module, configured to determine whether to adjust the current negative pressure in the negative pressure drainage of the target patient based on at least one target negative pressure and the corresponding at least one target duration range during the negative pressure drainage of historical patients when the negative pressure drainage of the target patient has not ended; the historical patients are patients of the target group type with wounds of the target wound type, the target negative pressure is the negative pressure that is easy to set for negative pressure drainage, and the target duration range is the duration range in which the negative pressure duration of the corresponding target negative pressure is easy to be when scars appear at the wound;

[0051] A negative pressure monitoring module, configured to, if so, determine the appropriate negative pressure matching the target patient and continue the negative pressure drainage of the target patient based on the appropriate negative pressure;

[0052] A duration determination module, configured to determine the appropriate interval duration for starting the pressure application for scar prevention treatment of the target patient based on at least one actual negative pressure and the corresponding actual duration during the negative pressure drainage of the target patient when the negative pressure drainage of the target patient ends;

[0053] A scar prevention module, configured to determine the appropriate applied pressure for the pressure application for scar prevention treatment of the target patient and perform the pressure application for scar prevention treatment on the target patient according to the appropriate interval duration and the appropriate applied pressure.

[0054] By adopting the above technical solutions, after the information acquisition module acquires the target group type and the target wound type, the adjustment determination module determines whether to adjust the current negative pressure in the negative pressure drainage of the target patient. Then, the negative pressure monitoring module determines the appropriate negative pressure matching the target patient and continues the negative pressure drainage of the target patient based on the appropriate negative pressure. Next, the duration determination module determines the appropriate interval duration for starting the pressure application for scar prevention treatment of the target patient. Finally, the scar prevention module performs the pressure application for scar prevention treatment on the target patient according to the appropriate interval duration and the appropriate applied pressure.

[0055] In the third aspect of the present application, a computer-readable storage medium is provided. A computer program is stored in the computer-readable storage medium. When the computer program is loaded and executed by a processor, the method steps described in any one of the first aspect are executed.

[0057] A processor, a memory, and a computer program stored in the memory and capable of running on the processor, the processor being configured to load and execute the computer program stored in the memory so that the electronic device executes the method described in any one of the first aspect.

[0058] In summary, the present application includes at least one of the following beneficial technical effects:

[0059] Based on the target negative pressure of historical patients and the corresponding target duration range, analyze the likelihood of the current negative pressure during negative pressure drainage of the target patient inducing scarring in the future, and then determine whether to adjust the current negative pressure. If it is determined that adjustment is needed, then determine the appropriate negative pressure and continue to drain with the appropriate negative pressure, thereby achieving scar prevention during the negative pressure drainage stage. Further, at the end of the negative pressure drainage, based on the actual negative pressure and the corresponding actual duration, analyze the optimal timing for applying pressure to prevent scarring, thereby determining the appropriate interval duration. Finally, according to the appropriate interval duration and the appropriate applied pressure, apply pressure to prevent scarring to the wound surface of the target patient at a reasonable timing and external pressure, thereby better improving the scar prevention effect at the wound surface.

[0066] See Figure 1 , the embodiments of the present application disclose a schematic flowchart of a wound surface pressure monitoring method for preventing scars, which can be implemented depending on a computer program or run on a wound surface pressure monitoring system for preventing scars based on the von Neumann architecture. This computer program can be integrated into an application or run as an independent tool-like application, and specifically includes:

[0067] S101: Obtain the target group type of the target patient and obtain the target wound type of the wound that the target patient has.

[0068] Specifically, in the embodiments of the present application, the target patient is a patient who has undergone repair treatment for an injured wound surface and requires scar prevention at the wound surface. The wound surface can be a wound surface after burn skin grafting. In other embodiments, it can also be a wound surface after treatment such as knife injury or laceration. The target group type is the group type divided based on the first basic information of the target patient. The first basic information of the target patient includes, but is not limited to, information such as age, underlying diseases, and family scar history. The target wound surface type is based on the second basic information of the wound surface of the target patient. The second basic information includes, but is not limited to, information such as the location, area, and depth of the wound surface. Further, the execution subject of a wound surface pressure supervision method for preventing scars disclosed in the embodiments of the present application is a server. The server is wirelessly connected to a terminal. A client related to wound surface pressure supervision is installed in the terminal. The server is the background server of the client, and specifically can be an independent physical server or a server cluster composed of multiple physical servers. The terminal can be a smart phone or a personal computer. A feasible way to obtain the target group type and the target wound surface type is as follows: Based on the electronic medical records of the target patient in the hospital, the first basic information and the second basic information are respectively obtained. The first basic information is input into a preset group type prediction model to obtain the target group type. The second basic information is input into a preset wound surface type prediction model to obtain the target wound surface type. Both the group type prediction model and the wound surface type prediction model are trained decision tree models or recurrent neural network models. The training process is briefly described as follows: Taking the group type prediction model as an example, the first basic information of the patients who have visited the hospital is marked with the correct group type, and then used as training samples to train the model. During the process, the model parameters are optimized through the reverse gradient algorithm until the model converges. This is the prior art and will not be elaborated here.

[0069] S102: When the negative pressure drainage of the target patient has not ended, based on at least one target negative pressure and the corresponding at least one target duration range during the negative pressure drainage of the historical patient, determine whether to adjust the current negative pressure in the negative pressure drainage of the target patient.

[0070] Specifically, the historical patients are patients of the target group type with wounds of the target wound type, the target negative pressure is the negative pressure that is easy to set for negative pressure drainage, and the target duration range is the duration range in which the negative pressure of the corresponding target negative pressure is likely to be when scars appear at the wound. It should be noted that after the repair of the injured wound, negative pressure drainage treatment is usually required for the wound to timely remove infectious tissue effusion, necrotic tissue, bacteria, etc., so as to reduce the number of bacteria on the wound and promote wound healing. In addition, negative pressure drainage will also affect the risk of scar formation at the subsequent wound. Exemplarily, the setting and monitoring of the wound negative pressure during negative pressure drainage have an impact on the risk of scar formation at the subsequent wound. If the wound negative pressure is too large or too small, it will not only affect the effect of negative pressure drainage, but also increase the risk of scar formation. Therefore, during the negative pressure drainage stage, the monitoring of the wound negative pressure is crucial for scar prevention.

[0071] Before the negative pressure drainage of the target patient is completed, retrieve the historical negative pressure monitoring records of the historical patients. The historical negative pressure monitoring records include, but are not limited to, the negative pressures set during negative pressure drainage for each historical patient, the duration of the negative pressure, and whether scars appear after the negative pressure drainage ends. Based on this historical negative pressure monitoring record, obtain the historical negative pressures in the negative pressure drainage performed by the historical patients, and count the first occurrence times of each historical negative pressure. The larger the first occurrence time, the easier it is for the historical patient to set the corresponding historical negative pressure for the wound during negative pressure drainage. Then, select the first number of historical negative pressures from each historical negative pressure in descending order of the first occurrence times and determine them as the target negative pressures. Further, obtain the historical duration range in which the duration of a single target negative pressure is located on the premise that scars appear at the historical patient's wound, and count the second occurrence times of each historical duration range. The larger the second occurrence time, the easier it is for scars to appear after the subsequent wound heals when the duration of the target negative pressure is within the corresponding historical duration range during negative pressure drainage. Then, select the second number of historical duration ranges from each historical duration range in descending order of the second occurrence times and determine them as the target duration range corresponding to the target negative pressure.

[0072] Further, determine the first weight of each target negative pressure. The first weight is the ratio of the first occurrence times of each target negative pressure to the sum of the first occurrence times of all target negative pressures. And determine the second weight of each target duration range corresponding to each target negative pressure. The second weight is the ratio of the second occurrence times of a single target duration range corresponding to the target negative pressure to the sum of the second occurrence times of all target duration ranges corresponding to the target negative pressure. Then, through a preset negative pressure drainage device, obtain the current negative pressure and the corresponding current duration in the negative pressure drainage of the target patient, that is, the negative pressure value currently set for the wound surface of the target patient and the duration of this negative pressure up to now. Further, when the current negative pressure is a target negative pressure, if the current duration is within the target duration range corresponding to the current negative pressure, then determine the corresponding target duration range as the first duration range, and calculate the first product of the first weight of this current negative pressure and the second weight of the corresponding first duration range. The larger the first product is, the greater the risk of scar formation at the subsequent wound surface under the current negative pressure with the current duration in the negative pressure drainage of the target patient. If the first product is greater than a preset first threshold, it indicates that if the negative pressure drainage continues with this current negative pressure, the risk of scar formation at the subsequent wound surface is relatively high. Then, determine to adjust this current negative pressure, so as to prevent scars in advance during the negative pressure drainage stage.

[0073] Further, when the current negative pressure is not a target negative pressure, determine the target negative pressure greater than the current negative pressure as the first negative pressure, determine the target negative pressure less than the current negative pressure as the second negative pressure, and determine the target duration range in which the current duration is located as the second duration range. Then calculate the second product of the first weight of the first negative pressure and the second weight of the corresponding second duration range, and calculate the third product of the first weight of the second negative pressure and the second weight of the corresponding second duration range. If both the second product and the third product are greater than the first threshold, it indicates that whether the negative pressure is greater than or less than the current negative pressure, the risk of scar formation at the subsequent wound surface is relatively high at the current duration. Furthermore, it shows that the current negative pressure needs to be adjusted. It should be noted that the supervision of the wound surface pressure can be the supervision of the negative pressure at the wound surface or the supervision of the external pressure at the wound surface.

[0074] S103: If so, determine the appropriate negative pressure matching the target patient, and continue the negative pressure drainage for the target patient based on the appropriate negative pressure.

[0075] Specifically, if it is determined that the current negative pressure needs to be adjusted for scar prevention, then an appropriate negative pressure matching the target patient is determined. In an embodiment of the present application, a feasible determination method is as follows: Obtain the remaining drainage duration sent by the doctor's terminal, that is, the duration for which this target patient still needs negative pressure drainage treatment. If this remaining drainage duration exists within the target duration range corresponding to the target negative pressure, then the corresponding target negative pressure is determined as the key negative pressure, and the target duration range in which the remaining drainage duration exists is determined as the key duration range. Further, calculate the fourth product of the first weight of each key negative pressure and the second weight of the corresponding key duration ranges. The smaller the fourth product, the smaller the possibility of scar formation at the subsequent wound surface when the key negative pressure corresponding to the negative pressure drainage lasts for this remaining drainage duration. Then, select the smallest fourth product from each of the fourth products, and determine the key negative pressure corresponding to the smallest fourth product as the appropriate negative pressure matching the target patient. Finally, adjust the current negative pressure to this appropriate negative pressure through the negative pressure drainage device, and continue to perform negative pressure drainage on the wound surface of the target patient with this appropriate negative pressure, which can not only optimize the effect of negative pressure drainage but also play a better role in preventing subsequent scars.

[0076] In other embodiments, if the first product is not greater than a preset first threshold, it indicates that the possibility of subsequent scar formation is relatively small when the current negative pressure is continuously applied for the duration within the first duration range. Then, subtract the current continuous duration from the end duration of the first duration range to obtain the remaining continuous duration. Then, compare the current continuous duration with a preset duration threshold, where the duration threshold is the minimum continuous duration for the target patient to feel discomfort under the current negative pressure. If the current continuous duration is greater than the duration threshold, it is determined that the current negative pressure needs to be adjusted; if the current continuous duration is not greater than the duration threshold, then calculate the duration difference obtained by subtracting the current continuous duration from the duration threshold. If the duration difference is not greater than the remaining continuous duration, then perform negative pressure adjustment after the duration difference; if the duration difference is greater than the remaining continuous duration, then when this duration threshold exists within the target duration range corresponding to the current negative pressure, determine the corresponding target duration range as the third duration range, calculate the product of the first weight of the current negative pressure and the second weight of the corresponding third duration range. If the product is not greater than the first threshold, then perform negative pressure adjustment after the duration threshold.

[0077] S104: At the end of the negative pressure drainage of the target patient, based on at least one actual negative pressure and the corresponding actual continuous duration during the negative pressure drainage of the target patient, determine the appropriate interval duration for starting the pressure application to prevent scarring for the target patient.

[0078] Specifically, when the negative pressure drainage of the target patient ends, it indicates that the wound surface of the target patient is approaching healing, and external pressure needs to be applied to the wound surface, that is, pressure is applied to prevent scarring, so as to prevent the appearance of scars. Furthermore, for the time of external pressure application, whether it is too early or too late, it will affect the scar prevention effect. In the embodiment of the present application, a feasible determination method is as follows: from the historical records of negative pressure drainage of the target patient by the negative pressure drainage device, at least one actual negative pressure and the corresponding actual duration in the negative pressure drainage of the target patient are obtained. Then, if the actual negative pressure is the target negative pressure, the corresponding actual negative pressure is determined as the important negative pressure, and when the actual duration of the important negative pressure is within the target duration range corresponding to the important negative pressure, the corresponding target duration range is determined as the important duration range. Next, calculate the fifth product of the first weight of each important negative pressure and the second weight of the corresponding important duration range, sum up each fifth product to obtain the corresponding sum of the first products. Finally, based on the sum of the first products, determine the appropriate interval duration between the pressure application for scar prevention treatment and the end of negative pressure drainage. The larger the sum of the first products, the greater the possibility of increasing the risk of scar appearance during the entire negative pressure drainage stage, and the more urgently scar prevention is needed after the end of negative pressure drainage, and the smaller the appropriate interval duration. Among them, in the embodiment of the present application, the appropriate interval duration corresponding to this sum of the first products is matched through a preset duration matching table. The duration matching table includes different sums of the first products and the corresponding interval durations, which are set based on the artificial experience of doctors. In addition, the pressure application for scar prevention treatment is mainly carried out by covering the wound surface with a silicone pressure pad and then moderately applying pressure bandaging with an elastic bandage. The appropriate interval duration is the duration between the time node of applying pressure for scar prevention treatment to the target patient and the time node of the end of negative pressure drainage.

[0079] S105: Determine the appropriate applied pressure when applying pressure for scar prevention treatment to the target patient, and perform pressure application for scar prevention treatment on the target patient according to the appropriate interval duration and the appropriate applied pressure.

[0080] Specifically, after determining the appropriate interval duration for applying pressure to prevent scarring in the target patient, it is necessary to further determine the appropriate applied pressure during the pressure application for scar prevention. A feasible determination method is as follows: Retrieve the historical pressure monitoring records of historical patients from the database. The historical pressure monitoring records include, but are not limited to, the duration from the end of negative pressure drainage to the start of pressure application for scar prevention for each historical patient, the magnitude of the externally applied pressure, and whether scars finally appear, etc. Based on this historical pressure monitoring record, obtain the interval duration from the start of pressure application for scar prevention in historical patients without scars, and count the first occurrence frequency of at least one historical duration range in which the interval duration is located. The greater the first occurrence frequency, the smaller the likelihood of scarring when the interval duration is within the corresponding historical duration range. Then, select the third number of historical duration ranges from each historical duration range in descending order of the first occurrence frequency and determine them as the target duration ranges, that is, the duration ranges where scars are not likely to appear. Further, obtain the historical pressures applied during pressure application for scar prevention in historical patients without scars whose interval duration is within a single target duration range, and count the second occurrence frequency of each historical pressure. The greater the second occurrence frequency, the smaller the likelihood of scarring when the interval duration is within a single target duration range and the corresponding historical pressure is externally applied for scar prevention. Then, select the fourth number of historical pressures from each historical pressure in descending order of the second occurrence frequency and determine them as the target pressures corresponding to this target duration range, that is, the external pressures where scars are not likely to appear.

[0081] Further, determine the third weight of each target duration range. The third weight is the ratio of the first occurrence frequency of each target duration range to the sum of the first occurrence frequencies of all target duration ranges. Then, determine the fourth weight of each target pressure corresponding to each target duration range. The fourth weight is the ratio of the second occurrence frequency of a single target pressure corresponding to the target duration range to the sum of the second occurrence frequencies of all target pressures corresponding thereto. Next, calculate the sixth product of the third weight of each target duration range and the fourth weights of the corresponding target pressures. The larger the sixth product, the smaller the possibility of scarring when the pressure applied is the corresponding target pressure while the interval duration for starting pressure application to prevent scarring is within a single target duration range. Then, sum up the sixth products to obtain the sum of the second products for the corresponding target duration range. The larger the sum of the second products, the smaller the possibility of subsequent scarring when the interval duration is within the corresponding target duration range. Further, determine the target duration range where the appropriate interval duration is located as the final duration range. If the sum of the second products corresponding to the final duration range is greater than a preset second threshold, it indicates that when the interval duration is within this final duration range, the possibility of subsequent scarring is relatively small, suggesting that applying pressure to prevent scarring after an appropriate interval duration at the end of negative pressure drainage has a better preventive effect. Then, it is determined that this appropriate interval duration is relatively reasonable, that is, the rationality verification passes, thus making the timing of applying pressure to prevent scarring more reasonable.

[0082] Further, after the rationality verification of the appropriate interval duration passes, determine the target pressures corresponding to the final duration range as the candidate pressures. Then, sum up all the sixth products corresponding to the same candidate pressure to obtain the corresponding sum of the third products. The larger the sum of the third products, the smaller the overall possibility of subsequent scarring when using this candidate pressure to apply pressure to prevent scarring, indicating that the scar prevention effect of this candidate pressure is better. Finally, select the largest sum of the third products from the sums of the third products, and determine the candidate pressure corresponding to the largest sum of the third products as the appropriate pressure to be applied when applying pressure to prevent scarring to the target patient. Further, after the appropriate interval duration, apply pressure to the wound surface of the target patient based on this appropriate pressure to be applied, thereby achieving better prevention of scarring.

[0083] The implementation principle of a wound pressure monitoring method for preventing scars in an embodiment of the present application is as follows: Based on the target negative pressure of historical patients and the corresponding target duration range, analyze the likelihood of the current negative pressure during negative pressure drainage of the target patient inducing scars in the future, and then determine whether to adjust the current negative pressure. If it is determined that adjustment is required, then determine the appropriate negative pressure and continue to perform drainage with the appropriate negative pressure, so as to prevent scars during the negative pressure drainage stage. Further, at the end of the negative pressure drainage, based on the actual negative pressure and the corresponding actual duration, analyze the optimal timing for performing pressure application to prevent scars, so as to determine the appropriate interval duration. Finally, according to the appropriate interval duration and the appropriate applied pressure, perform pressure application to prevent scars on the wound of the target patient at a reasonable timing and external pressure, so as to better improve the prevention effect of scars at the wound site.
