Description

Technical Field

[0001] The present application relates to the technical field of negative pressure drainage, and in particular to a monitoring method, device, medium and equipment for negative pressure drainage after burn skin grafting. Background Art

[0002] Burn skin grafting is a medical technology that covers and repairs burn wounds by transplanting one's own skin or other biological materials. The main purpose is to provide new blood and nutrition supply to the burn site by transplanting healthy skin tissue, thereby accelerating the healing process of the wound. After the burn skin grafting surgery, in order to further and better promote the good healing of the wound, negative pressure drainage technology is usually used to apply negative pressure to the grafted wound for recovery. Negative pressure drainage technology is a new technology for treating wounds developed in recent years. It uses a biological semipermeable membrane to close the open wound, uses a special negative pressure machine to generate a certain negative pressure, and acts on the wound after debridement through drainage tubes and dressings, so that the wound is in a negative pressure environment, thereby better discharging exudate and improving the recovery effect of skin grafting.

[0003] At present, during the process of negative pressure drainage for patients with burn skin grafts, the patients' daily activities are usually not restricted. Therefore, if the patients are not vigilant during their daily activities, it is easy for the dressing to loosen and create gaps between the skin due to posture problems. The negative pressure environment at the wound surface will be destroyed, resulting in poor recovery effect of negative pressure drainage on the patients. Summary of the invention

[0004] In order to improve the recovery effect of negative pressure drainage on patients, the present application provides a monitoring method, device, medium and equipment for negative pressure drainage after burn skin grafting.

[0005] In a first aspect of the present application, a method for monitoring negative pressure drainage after burn skin grafting is provided, which specifically comprises: Acquiring at least one actual activity posture of a target patient within a preset time period before a current time, wherein the target patient is a patient undergoing negative pressure drainage treatment after burn skin grafting; Determine the risk value of the dressing at the skin grafting site at the current time to be loosened based on the skin grafting site of the target patient, each of the actual activity postures, at least one target activity posture of the burn skin grafting patient that is likely to cause the dressing to loosen between the skin, and at least one corresponding target site, wherein the target site is a body site where the corresponding target activity posture is likely to cause the dressing to loosen between the skin, and the greater the risk value, the more likely the dressing at the skin grafting site is to be loosened at the current time; The risk value is compared with a preset risk threshold. If the risk value exceeds the risk threshold, a risk reminder is sent to the doctor's terminal. The risk reminder is used to remind the doctor that there is a risk of the negative pressure environment being destroyed during the negative pressure drainage treatment.

[0006] By adopting the above technical solution, after obtaining the actual activity posture of the target patient within the preset time before the current time, the risk value of the dressing loosening at the skin grafting site is determined based on the target activity posture and corresponding target site that are prone to cause the dressing to loosen in the burn skin grafting patient, as well as the actual skin grafting site of the target patient and the actual activity posture that has occurred, so as to accurately analyze the possibility of the dressing loosening at the skin grafting site of the target patient at the current time. Finally, if the risk value exceeds the risk threshold, it means that the overall possibility of the dressing loosening at the skin grafting site of the target patient at the current time is relatively high, and it is easier to produce gaps, destroying the negative pressure environment of the skin grafting site, which is not conducive to the discharge of exudate from the wound surface of the skin grafting site under the action of negative pressure, thereby affecting the recovery effect of the wound surface of the skin grafting site, then a risk reminder is sent to the doctor's terminal to remind the doctor to go for investigation in time, which is conducive to improving the recovery effect of negative pressure drainage on patients.

[0007] Optionally, the step of determining the risk value of the dressing loosening at the skin grafting site at the current time based on the skin grafting site of the target patient, each of the actual activity postures, at least one target activity posture of the burn skin grafting patient that is likely to cause the dressing to loosen between the skin and the skin, and at least one corresponding target site, specifically includes: Obtaining the first history of burn skin graft patients with a history of loosening of the dressing and skin, counting the first occurrence times of each of the historical activity postures, and selecting the first historical activity posture from each of the historical activity postures in descending order of the first occurrence times as the target activity posture; Obtaining historical parts where the dressing and the skin are loosened when the first historical patient has a single target activity posture, counting the second occurrence times of each historical part, and selecting the historical part with the second occurrence times from each historical part in descending order as the target part of the corresponding target activity posture; Calculate a first weight of each target activity posture and a second weight of each corresponding target part, wherein the first weight is a ratio of a first occurrence number of each target activity posture to a sum of first occurrence numbers of all target activity postures, and the second weight is a ratio of a second occurrence number of a single target part corresponding to the target activity posture to a sum of second occurrence numbers of all corresponding target parts; The risk value of loosening of the dressing at the skin grafting site at the current time is determined according to the skin grafting site of the target patient, each of the actual activity postures, the first weight and the corresponding second weights.

[0008] By adopting the above technical solution, the greater the number of first occurrences, the more likely the corresponding historical activity posture will cause the dressing to loosen with the skin, destroying the negative pressure environment during negative pressure drainage, and thus determining the target activity posture; the greater the number of second occurrences, the greater the possibility of looseness between the dressing and the skin at the corresponding historical site when the first historical patient makes the target activity posture, and thus determining the target site. Finally, combining the first weight and the corresponding second weights, the possibility of loose dressing in the target patient at this skin grafting site and actual activity posture is analyzed, and then the possibility of loose dressing at the skin grafting site is more accurately assessed, thereby achieving subsequent accurate early warning.

[0009] Optionally, determining the risk value of the dressing loosening at the skin grafting site at the current time according to the skin grafting site of the target patient, each of the actual activity postures, the first weight and each corresponding second weight specifically includes: Determine the target activity posture of the skin grafting part in the corresponding target parts as the key activity posture, and calculate the first product of the first weight of at least one actual activity posture in each key activity posture and the second weight of the corresponding skin grafting part; The first products are summed to obtain the sum of the first products, and the sum of the first products is determined as the risk value of the dressing loosening at the skin grafting site at the current time.

[0010] By adopting the above technical solution, the larger the first product is, the greater the possibility that the dressing at the skin graft site will loosen when the target patient makes the corresponding actual activity posture. Then, the first products are summed to obtain the sum of the first products. The larger the sum of the first products is, the greater the overall possibility that the dressing at the skin graft site of the target patient will loosen at the current time. Then, the sum of the first products is determined as the risk value of loosening of the dressing at the skin graft site at the current time, thereby accurately judging whether there is a risk of damage to the negative pressure environment of the skin graft site.

[0011] Optionally, the method further includes: If the risk value does not exceed the risk threshold, calculating a second product of a first weight of at least one actual activity posture existing in each of the target activity postures and a second weight of each corresponding target part, and summing each of the second products to obtain a sum of the second products of the corresponding actual activity postures; Summing the sums of the second products to obtain a final product sum, and comparing the final product sum with a preset product sum threshold; If the final sum of the products is greater than the product sum threshold, it is determined whether there is a first risk in the drainage tube, and when the first risk exists, a blockage troubleshooting reminder is sent to the terminal, where the first risk is a risk of blockage of the drainage tube; If the final sum of the products is not greater than the product sum threshold, it is determined whether the target patient has a second risk. When the second risk exists, the negative pressure drainage is temporarily treated with a reduced blood pressure, and the second risk is the risk of discomfort caused by continuous negative pressure.

[0012] By adopting the above technical solution, if the risk value does not exceed the risk threshold, it means that the possibility of loosening of the dressing at the skin grafting site of the target patient at the current time is small, and there is a high probability that there will be no loosening between the dressing and the skin. Further, if the final sum of products is greater than the sum of products threshold, it means that the actual activity posture within the preset time before the current time causes a large degree of contraction and extension of the body parts, which affects blood circulation and lymphatic return, so that the possibility of increased wound exudate at the skin grafting site at the current time is large. In this case, it is necessary to monitor the blockage of the drainage tube in time to avoid the exudate from not being removed in time and effectively; if the final sum of products is not greater than the sum of products threshold, it means that the possibility of increased wound exudate at the skin grafting site at the current time is small, and the drainage tube needs to remove less exudate, then it is necessary to determine whether the target patient has discomfort caused by continuous negative pressure, so as to avoid the target patient from experiencing uncomfortable negative pressure drainage.

[0013] Optionally, the determining whether there is a first risk in the drainage tube specifically includes: Acquire at least one drainage velocity of the drainage tube within the preset time period; Based on each drainage speed, a corresponding actual speed change curve is drawn, and the actual speed change curve is fitted with a preset normal speed change curve to obtain a fitting rate; If the fitting rate is less than a preset fitting rate threshold, it is determined that there is a first risk in the drainage tube; if the fitting rate is not less than the preset fitting rate threshold, it is determined that there is no first risk in the drainage tube.

[0014] By adopting the above technical solution, if this fitting rate is less than the preset fitting rate threshold, it means that the actual speed change curve is less similar to the normal speed change curve, and there is a high probability of blockage risk, then it is determined that there is a first risk in the drainage tube; otherwise, it is determined that there is no first risk in the drainage tube.

[0015] Optionally, the determining whether the target patient has a second risk specifically includes: Determine a patient portrait of the target patient, and obtain a historical negative pressure duration range during which a second historical patient of the patient portrait felt discomfort due to continuous negative pressure, wherein the skin grafting site of the second historical patient is the same as the skin grafting site of the target patient; Counting the first occurrence frequency of each of the historical negative pressure duration ranges, and selecting the third historical negative pressure duration range from each of the historical negative pressure duration ranges in descending order of the first occurrence frequency to determine as the target duration range; Obtaining a historical negative pressure value range in which the second patient was in each of the target duration ranges when the continuous negative pressure caused discomfort, counting the second occurrence frequency of each of the historical negative pressure value ranges, and selecting a fourth number of historical negative pressure value ranges from each of the historical negative pressure value ranges in descending order of the second occurrence frequency to determine as the target negative pressure range for the corresponding target duration range; Calculating a third weight of each target duration range and a fourth weight of each corresponding target negative pressure range, wherein the third weight is a ratio of a first occurrence frequency of each target duration range to a sum of first occurrence frequencies of all target duration ranges, and the fourth weight is a ratio of a second occurrence frequency of a single target negative pressure range corresponding to the target duration range to a sum of second occurrence frequencies of all corresponding target negative pressure ranges; It is determined whether the target patient has a second risk based on the third weight and the corresponding fourth weights.

[0016] By adopting the above technical scheme, the greater the first occurrence frequency, the more likely the target patient will feel discomfort caused by negative pressure when the negative pressure duration is within the corresponding historical negative pressure duration range, and the target duration range is determined; the greater the second occurrence frequency, the more likely the target patient will feel discomfort when the negative pressure duration is within the target duration range and the set negative pressure value is within the corresponding historical negative pressure value range, and the target negative pressure range is determined; finally, the third weight and the corresponding fourth weights are combined to analyze the possibility of discomfort in the target patient under the negative pressure duration and negative pressure size at the current time, and thus more accurately determine whether there is a second risk.

[0017] Optionally, determining whether the target patient has a second risk according to the third weight and the corresponding fourth weights specifically includes: Determining a target negative pressure duration of the target patient based on the current time and the start time of the negative pressure drainage; Determine the target duration range in which the target negative pressure duration is located as the key duration range, calculate the third product of the third weight of the key duration range and the corresponding fourth weight of each target negative pressure range, and sum them to obtain the corresponding sum of the third products; Determine the target duration range after the target negative pressure duration as an important duration range, calculate and sum the fourth products of the third weight of each important duration range and the corresponding fourth weights of each target negative pressure range, obtain the corresponding sum of the fourth products, and sum the sums of the fourth products to obtain a re-sum result; If the sum of the third products is greater than the re-summed result, it is determined that the target patient has a second risk.

[0018] By adopting the above technical solution, the larger the sum of the third products is, the greater the possibility that the target patient will feel uncomfortable due to continuous negative pressure at the current time, and the larger the sum of the fourth products is, the greater the possibility that the target patient will feel uncomfortable due to the continuous negative pressure within the corresponding important duration. Further, the sum of each fourth product is summed to obtain a re-requirement and result. The larger the re-requirement and result is, the greater the possibility that the target patient will feel uncomfortable due to continuous negative pressure after the current time. If the sum of the third products is greater than the re-requirement and result, it means that the target patient is more likely to feel uncomfortable at the current time, then it is determined that the target patient has a second risk, thereby more accurately determining whether the target patient has a second risk at the current time.

[0019] In a second aspect of the present application, a monitoring device for negative pressure drainage after burn skin grafting is provided, which specifically comprises: An information acquisition module, used to acquire at least one actual activity posture of a target patient within a preset time period before a current time, wherein the target patient is a patient undergoing negative pressure drainage treatment after burn skin grafting; a risk determination module, for determining a risk value of the dressing at the skin grafting site being loose at the current time based on the skin grafting site of the target patient, each of the actual activity postures, at least one target activity posture of the burn skin grafting patient that is likely to cause the dressing to loosen between the skin, and at least one corresponding target site, wherein the target site is a body site where the corresponding target activity posture is likely to cause the dressing to loosen between the skin, and the greater the risk value, the more likely the dressing at the skin grafting site is to be loose at the current time; The risk reminder module is used to compare the risk value with a preset risk threshold. If the risk value exceeds the risk threshold, a risk reminder is sent to the doctor's terminal. The risk reminder is used to remind the doctor that there is a risk of the negative pressure environment being destroyed during the negative pressure drainage treatment.

[0020] By adopting the above technical solution, the information acquisition module obtains at least one actual activity posture within a preset time before the current time, and then the risk determination module determines the risk value of loosening of the dressing at the skin grafting site of the target patient at the current time. Finally, the risk reminder module sends a risk reminder to the doctor's terminal in time when the risk value exceeds the risk threshold.

[0021] In a third aspect of the present application, a computer-readable storage medium is provided, in which a computer program is stored. When the computer program is loaded and executed by a processor, the method steps described in any one of the first aspects are performed.

[0022] In a fourth aspect of the present application, an electronic device is provided, specifically comprising: A processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein the processor is used to load and execute the computer program stored in the memory so that the electronic device performs the method as described in any one of the first aspects.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: determining the risk value of loose dressing at the skin grafting site, thereby accurately analyzing the possibility of loose dressing at the skin grafting site of the target patient at the current time. Finally, if the risk value exceeds the risk threshold, it means that the overall possibility of loose dressing at the skin grafting site of the target patient at the current time is relatively high, and it is easier to produce gaps, destroying the negative pressure environment of the skin grafting site, which is not conducive to the discharge of exudate from the wound surface of the skin grafting site under the action of negative pressure, and further affecting the recovery effect of the wound surface of the skin grafting site. Then, a risk reminder is sent to the doctor's terminal to remind the doctor to go for investigation in time, which is conducive to improving the recovery effect of negative pressure drainage on patients.

[0029] See also Figure 1 The present application embodiment discloses a flow chart of a method for monitoring negative pressure drainage after burn skin grafting, which can be implemented by a computer program or run on a monitoring device for negative pressure drainage after burn skin grafting based on the von Neumann system. The computer program can be integrated into an application or run as an independent tool application, specifically including: S101: Acquire at least one actual activity posture of a target patient within a preset time period before the current time.

[0030] Specifically, in the embodiment of the present application, the target patient is a patient who has undergone a burn skin grafting operation and negative pressure drainage treatment. The preset duration may be the interval duration for monitoring the postoperative negative pressure drainage situation. In other embodiments, the postoperative negative pressure drainage situation is monitored in real time. The preset duration may be 5 hours or other reasonable durations. The actual activity posture is the posture change that occurs during the negative pressure drainage treatment of the target patient within the preset duration before the current time. For example, the actual activity posture may be from lying flat to sitting, from lying flat to lying on the side, and so on.

[0031] In addition, the execution subject of a method for monitoring negative pressure drainage after skin grafting for burns in the application embodiment is a server, and the server is wirelessly connected to the terminal and the infrared sensor. The infrared sensor captures the activity posture of the target patient in real time to obtain a capture result, wherein the capture result includes the captured activity posture and the corresponding capture time node. The terminal can be a doctor's personal computer or tablet computer, and a client or applet for negative pressure drainage monitoring is installed in the terminal. The server can be a background server of the client or applet, specifically an independent physical server, or a server cluster or distributed system composed of multiple physical servers. Furthermore, a feasible way to obtain at least one actual activity posture within a preset time length is: based on the current time and the preset time length, determine the time period for obtaining the actual activity posture, and then filter out the activity posture whose capture time node is within the time period from the capture result, and determine it as the actual activity posture.

[0032] S102: Based on the skin grafting site of the target patient, each actual activity posture, at least one target activity posture of the burn skin grafting patient that is likely to cause the dressing to loosen between the skin and the skin, and at least one corresponding target site, determine the risk value of the dressing loosening at the skin grafting site at the current time.

[0033] Specifically, after the actual activity posture is determined, the doctor retrieves the fitting condition of the first historical patient who performed negative pressure drainage on the burn skin graft, that is, the historical inspection record of the fitting condition of the dressing and the skin graft wound. The historical inspection record includes but is not limited to the body parts where the dressing and the skin have loosened and the historical activity postures that induced the loose fitting. Based on the above historical inspection records, the historical activity postures accompanied by the loose fitting of the dressing and the skin of the first historical patient with burn skin grafting are obtained, and the first occurrence number of each historical activity posture is counted. The larger the first occurrence number, the more likely the corresponding historical activity posture will cause the dressing to loosen and destroy the negative pressure environment during negative pressure drainage, resulting in poor recovery of the skin graft wound. Then, in the order of the first occurrence number from large to small, the historical activity posture with the first number is selected from each historical activity posture to determine as the target activity posture, that is, the historical activity posture that is more likely to cause the dressing and skin in the skin graft area to loosen. Furthermore, based on the above historical examination records, the historical parts where the dressing and the skin are loose when the first historical patient has a single target activity posture are obtained, and the second occurrence number of each historical part is counted. The larger the second occurrence number, the greater the possibility that the dressing and the skin of the corresponding historical part are loose when the first historical patient makes the target activity posture. Then, in order of the second occurrence number from large to small, the historical part with the second number is selected from each historical part to be determined as the target part of the corresponding target activity posture, that is, the body part where the dressing and the skin are more likely to be loose. It should be noted that the dressing is used to cover or fill the skin graft wound surface, maintain the cleanliness and sterility of the wound surface, and play a role in maintaining the negative pressure environment of the skin graft wound surface.

[0034] Further, the first weight of each target activity posture and the second weight of each corresponding target part are calculated, the first weight being the ratio of the first occurrence number of each target activity posture to the sum of the first occurrence numbers of all target activity postures, and the second weight being the ratio of the second occurrence number of a single target part corresponding to the target activity posture to the sum of the second occurrence numbers of all corresponding target parts. Further, it is necessary to determine the risk value of the loosening of the dressing at the skin grafting part of the target patient at the current time according to each second weight corresponding to the sum of the first weight, that is, the risk of loosening between the dressing and the skin. In the present application, a feasible determination method is: determine the target activity posture of the skin grafting site in each corresponding target site as the key activity posture, calculate the first product of the first weight of at least one actual activity posture existing in each key activity posture and the second weight of the corresponding skin grafting site, the larger the first product is, the greater the possibility of loosening of the dressing at the skin grafting site when the corresponding actual activity posture is made, and then sum up each first product to obtain the sum of the first products. The larger the sum of the first products is, the greater the overall possibility of loosening of the dressing at the skin grafting site of the target patient at the current time, and then determine the sum of the first products as the risk value of loosening of the dressing at the skin grafting site at the current time.

[0035] S103: Compare the risk value with a preset risk threshold, and if the risk value exceeds the risk threshold, send a risk reminder to the doctor's terminal.

[0036] Specifically, after the risk value of the dressing loosening at the skin grafting site at the current time is determined, the risk value is compared with the preset risk threshold. If the risk value exceeds the risk threshold, it means that the overall possibility of the dressing loosening at the skin grafting site of the target patient at the current time is relatively high, and it is easier to produce gaps, causing air to enter the negative pressure system, destroying the negative pressure environment at the skin grafting site, thereby affecting the negative pressure drainage effect, which is not conducive to the discharge of exudate from the wound at the skin grafting site under the action of negative pressure, and further affecting the recovery effect of the wound at the skin grafting site. Then a risk reminder is sent to the doctor's terminal, which can be a personal computer or a smart phone. Among them, the risk reminder is used to remind the doctor that there is a risk of the negative pressure environment being destroyed during the negative pressure drainage treatment, so as to promptly remind the doctor to go for examination.

[0037] See also Figure 2 The present application embodiment discloses a flow chart of another method for monitoring negative pressure drainage after burn skin grafting, which can be implemented by a computer program or run on a monitoring device for negative pressure drainage after burn skin grafting based on the von Neumann system. The computer program can be integrated into an application or run as an independent tool application, specifically including: S201: Acquire at least one actual activity posture of a target patient within a preset time period before the current time.

[0038] S202: Based on the skin grafting site of the target patient, each actual activity posture, at least one target activity posture of the burn skin grafting patient that is likely to cause the dressing to loosen between the skin and the skin, and at least one corresponding target site, determine the risk value of the dressing loosening at the skin grafting site at the current time.

[0039] S203: Compare the risk value with a preset risk threshold, and if the risk value exceeds the risk threshold, send a risk reminder to the doctor's terminal.

[0040] For details, please refer to steps S101-S103, which will not be described in detail here.

[0041] S204: If the risk value does not exceed the risk threshold, calculate the second product of the first weight of at least one actual activity posture existing in each target activity posture and the second weight of each corresponding target part, and sum the second products to obtain the sum of the second products of the corresponding actual activity postures.

[0042] S205: summing up the sums of the second products to obtain a final product sum, and comparing the final product sum with a preset product sum threshold.

[0043] S206: If the final sum of the products is greater than the product sum threshold, it is determined whether there is a first risk in the drainage tube, and when there is a first risk, a blockage inspection reminder is sent to the terminal.

[0044] Specifically, if the risk value does not exceed the risk threshold, it means that the possibility of loosening of the dressing at the skin grafting site of the target patient at the current time is small, and there is a high probability that loosening will not occur between the dressing and the skin, then the first weight and the corresponding second weights are determined, and the details can be found in step S102, which will not be repeated here. Then, the second product of the first weight of at least one actual activity posture existing in each target activity posture and the corresponding second weight of each target part is calculated, and each second product is summed to obtain the sum of the second products of the corresponding actual activity postures. The larger the sum of the second products, the greater the possibility that the dressing will loosen due to contraction and extension of the body part when the target patient makes the corresponding actual activity posture, which indicates that the degree of contraction and extension of the body part caused by the corresponding actual activity posture is greater. Furthermore, the sum of the second products is summed to obtain a final product sum, and the final product sum is compared with a preset product sum threshold. If the final product sum is greater than the product sum threshold, it means that the actual activity posture within the preset time before the current time has caused a large degree of contraction and extension of body parts, affecting blood circulation and lymphatic return, thereby making it more likely that the wound exudate at the skin grafting site at the current time will increase, and the drainage tube needs to drain more exudate. In this case, it is necessary to monitor the blockage of the drainage tube in time, that is, to determine whether there is a first risk in the drainage tube, so as to avoid the exudate from not being cleared in time and effectively, wherein the first risk is the risk of drainage tube blockage. In the embodiment of the present application, a feasible judgment method is: from the flow rate of the exudate in the drainage tube obtained in real time by the preset ultrasonic flowmeter or hot film flowmeter, at least one drainage speed of the drainage tube within the preset time before the current time is obtained, based on each drainage speed, the corresponding actual speed change curve is drawn by the preset MATLAB tool, that is, the curve of the drainage speed changing with time within the preset time, and then the actual speed change curve is fitted with the preset normal speed change curve by the MATLAB tool to obtain the fitting rate, and the normal speed change curve is the curve of the drainage speed changing with time when the drainage tube is not blocked. If this fitting rate is less than the preset fitting rate threshold, it means that the similarity between the actual speed change curve and the normal speed change curve is low, and there is a high probability of blockage risk, then it is determined that there is a first risk in the drainage tube; otherwise, it is determined that there is no first risk in the drainage tube. Finally, when it is determined that there is a first risk, a blockage inspection reminder is sent to the doctor's terminal, so as to promptly remind the doctor to check whether the drainage tube is blocked, so that more exudate generated can be discharged in time, and the recovery effect of the skin grafting wound is improved.

[0045] S207: If the final sum of the products is not greater than the product sum threshold, it is determined whether the target patient has a second risk. If the second risk exists, a short-term blood pressure reduction treatment is performed on the negative pressure drainage.

[0046] Specifically, if the final sum of the products is not greater than the sum of the products threshold, it means that the possibility of an increase in wound exudate at the skin grafting site at the current time is small, and the drainage pressure of the drainage tube on the exudate is relatively small. Then, it is judged whether the target patient has a second risk at this time, that is, the risk of discomfort caused by continuous negative pressure. A feasible judgment method is: input the basic information of the target patient registered in the hospital into a preset portrait prediction model to determine the patient portrait of the target patient, wherein the basic information includes but is not limited to the name, gender, age and underlying disease of the target patient. The portrait prediction model can be a trained decision tree model or a random forest model. The training process is briefly described as follows: the basic information of historical patients marked with portraits is used as training samples to train the model. During the process, the parameters are optimized through the reverse gradient algorithm until the model converges. This is a prior art and will not be repeated here.

[0047] Furthermore, retrieve the historical monitoring records of negative pressure drainage discomfort of historical patients who underwent negative pressure drainage with skin grafting for burns, including but not limited to the duration of negative pressure drainage of historical patients, the size of negative pressure setting, and the existence of discomfort problems caused by continuous negative pressure. Based on this historical monitoring record, obtain the historical negative pressure duration range in which the second historical patient in the patient portrait felt discomfort due to continuous negative pressure, and the skin grafting site of the second historical patient is the same as the skin grafting site of the target patient. Further, count the first occurrence frequency of each historical negative pressure duration range, and the greater the first occurrence frequency, the more likely the target patient will feel discomfort caused by negative pressure when the negative pressure duration is within the corresponding historical negative pressure duration range. In order of the first occurrence frequency from large to small, select the third number of the historical negative pressure duration range from each historical negative pressure duration range to determine it as the target duration range, that is, the negative pressure duration range that is likely to cause discomfort to the target patient.

[0048] Furthermore, based on the above historical monitoring records, the historical negative pressure value range where the continuous negative pressure causes discomfort under a single target duration range is obtained, that is, the range of the negative pressure value set during negative pressure drainage, and the second occurrence frequency of each historical negative pressure value range is counted. The larger the second occurrence frequency, the more likely it is to cause discomfort to the target patient when the negative pressure duration is within the target duration range and the set negative pressure value is within the corresponding historical negative pressure value range. Then, in descending order of the second occurrence frequency, the fourth number of the historical negative pressure value range is selected from each historical negative pressure value range to determine it as the target negative pressure range of the corresponding target duration range, that is, the negative pressure value range that is likely to cause discomfort.

[0049] Further, the third weight of each target duration range and the fourth weight of each corresponding target negative pressure range are calculated, 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 negative pressure range corresponding to the target duration range to the sum of the second occurrence frequencies of all corresponding target negative pressure ranges. Finally, according to the third weight and the corresponding fourth weights, it is determined whether the target patient has a second risk. A feasible determination method is: subtract the start time of negative pressure drainage for the target patient from the current time to obtain the target negative pressure duration of the target patient, determine the target duration range where the target negative pressure duration is located as the key duration range, then calculate the third product of the third weight of the key duration range and the fourth weight of each corresponding target negative pressure range and sum them to obtain the corresponding sum of the third products. The larger the sum of the third products, the greater the possibility that the target patient will feel uncomfortable due to continuous negative pressure at the current time.

[0050] Further, the target duration range after the target negative pressure duration is determined as the important duration range, and the duration within the important duration range is greater than the target negative pressure duration. The fourth product of the third weight of each important duration range and the corresponding fourth weight of each target negative pressure range is calculated and summed to obtain the corresponding sum of the fourth products. The larger the sum of the fourth products, the greater the possibility that the target patient will feel uncomfortable when the negative pressure duration is within the corresponding important duration range. Further, the sum of each fourth product is summed to obtain a re-required sum result. The larger the re-required sum result, the greater the possibility that discomfort will be caused by continuous negative pressure after the current time. If the sum of the third products is greater than the re-required sum result, it means that the target patient is more likely to feel uncomfortable at the current time, and then it is determined that the target patient is at a second risk.

[0051] Finally, when it is determined that there is a second risk, and the exudate that needs to be removed is not large, in order to avoid the target patient from feeling uncomfortable and not responding in time, the negative pressure drainage is temporarily reduced. A feasible implementation method is: sending a reminder of the discomfort caused by continuous negative pressure to the doctor's terminal, receiving the negative pressure adjustment instruction sent by the terminal, and controlling the negative pressure drainage device to adjust the negative pressure value according to the negative pressure adjustment instruction. In other embodiments, if there is no second risk, the actual negative pressure value at the current time is obtained by the negative pressure drainage device, and the target negative pressure range containing this actual negative pressure value is determined as the important negative pressure range, and the third weight of at least one important duration range of this important negative pressure range in each corresponding target negative pressure range is calculated, and the weight product of the fourth weight of the corresponding important negative pressure range is multiplied, and the maximum weight product is selected from each weight product, and the important duration range corresponding to the maximum weight product is determined as the duration range that needs to be reminded, and when the negative pressure duration of the subsequent target patient is in this duration range that needs to be reminded, a reminder is sent to the terminal.

[0052] The implementation principle of the monitoring method of negative pressure drainage after burn skin grafting in the embodiment of the present application is: determine the risk value of loose dressing at the skin grafting site, so as to accurately analyze the possibility of loose dressing at the skin grafting site of the target patient at the current time. Finally, if the risk value exceeds the risk threshold, it means that the overall possibility of loose dressing at the skin grafting site of the target patient at the current time is relatively large, and it is easier to produce gaps, destroying the negative pressure environment of the skin grafting site, which is not conducive to the discharge of exudate from the wound surface of the skin grafting site under the action of negative pressure, and further affecting the recovery effect of the wound surface of the skin grafting site. Then, a risk reminder is sent to the doctor's terminal to remind the doctor to go for investigation in time, which is conducive to improving the recovery effect of negative pressure drainage on the patient.
