Description

Technical Field

[0001] The present application relates to the technical field of negative pressure drainage, and in particular to a cleaning control method, device, storage medium and electronic equipment for a negative pressure drainage tube. Background Art

[0002] Since its introduction, negative pressure drainage technology has been widely used in the field of surgery. It promotes blood circulation in the wound and accelerates the discharge of exudate by applying negative pressure on the wound, thereby significantly improving the speed and quality of wound healing. From the early simple negative pressure suction device to today's intelligent, multifunctional negative pressure drainage system, this technology has continued to evolve, providing a more effective means for clinical treatment. But no matter how the technology advances, the problem of drainage tube blockage has always been a major problem that plagues clinical treatment. Once the drainage tube is blocked, the pus produced by the wound cannot be discharged in time, and will accumulate locally, forming an environment that is conducive to the growth of bacteria, leading to the spread of infection, making the wound that could have healed smoothly become more complicated, increasing the patient's pain and treatment costs.

[0003] At present, the usual treatment process for drainage tube blockage is: relying on the experience of medical staff, according to the color, flow rate and other information of the exudate in the drainage tube, discover the blockage of the drainage tube, and finally manually flush the blockage of the drainage tube. In judging the blockage of the drainage tube, this method is highly subjective, and when the drainage tube is slightly blocked or blocked in the early stage, it is difficult to detect it in time and accurately through this method. By the time the staff detects the blockage, the problem is often more serious. At this time, manual flushing of the drainage tube has a poor flushing effect on the drainage tube. Summary of the invention

[0004] In order to improve the flushing effect of the drainage tube, the present application provides a cleaning control method, device, storage medium and electronic equipment for a negative pressure drainage tube.

[0005] In a first aspect of the present application, a method for cleaning a negative pressure drainage tube is provided, which specifically includes: Obtain the actual drainage speed and actual negative pressure of the current negative pressure drainage tube of the target patient; When the actual drainage speed is not in the corresponding normal speed interval, based on the actual drainage speed, the actual negative pressure, the target speed interval of the historical patient and at least one corresponding target negative pressure interval, determine whether the target patient has a risk of negative pressure drainage tube blockage, the target speed interval is a speed interval in which the negative pressure drainage speed is easily located when the historical patient has a wound infection, the target negative pressure interval is a negative pressure interval in which the negative pressure is easily located when the historical patient has a wound infection and the cause is drainage tube blockage, the historical patient and the target patient are consistent in patient portrait and wound type; If so, determine the target flushing speed for flushing the negative pressure drainage tube; Determine the risk coefficient of wound infection of the target patient, and based on the risk coefficient, determine the target drug concentration of the anti-infection drug in the flushing solution when flushing the negative pressure drainage tube; Flush the negative pressure drainage tube according to the target flushing speed and the target drug concentration.

[0006] By adopting the above technical solution, after obtaining the actual drainage speed and the actual negative pressure magnitude, if the actual drainage speed is not within the corresponding normal speed range, it indicates that the current drainage speed is slow and there may be a risk of blockage of the negative pressure drainage tube, which needs to be further verified. Then, based on the target speed range and the corresponding target negative pressure range, analyze the likelihood of wound infection caused by blockage in the target patient under the actual drainage speed and the actual negative pressure magnitude, and then more accurately determine whether the target patient has a blockage risk. If there is a blockage risk, then specifically determine the target flushing speed for flushing, and reasonably determine the target drug concentration of the anti-infection drug in the flushing solution according to the risk coefficient of wound infection of the target patient. By timely monitoring the blockage risk, once the negative pressure drainage tube is indeed blocked, it can be flushed in a timely manner with this target flushing speed and target drug concentration, and the flushing effect is better. Avoid flushing after a real blockage occurs, as the flushing effect is poor.

[0007] Optionally, the determining whether the target patient has a risk of blockage of the negative pressure drainage tube based on the actual drainage speed, the actual negative pressure magnitude, the target speed range of historical patients, and the corresponding at least one target negative pressure range specifically includes: Obtain the historical speed range in which the negative pressure drainage speed is located when a historical patient has a wound infection, count the first occurrence times of each historical speed range, and select the first number of historical speed ranges from each historical speed range in descending order of the first occurrence times and determine them as the target speed range; Obtain the historical negative pressure range in which the negative pressure magnitude is set when a historical patient has a wound infection and the cause is blockage of the negative pressure drainage tube and the negative pressure drainage speed is within a single target speed range, and count the second occurrence times of each historical negative pressure range; Select the second number of historical negative pressure ranges from each historical negative pressure range in descending order of the second occurrence times and determine them as the target negative pressure range corresponding to a single target speed range; Determine the first weight for each of the target speed intervals, and determine the second weight for the target negative pressure interval corresponding to each target speed interval. The first weight is the ratio of the first occurrence times of each target speed interval to the sum of the first occurrence times of all target speed intervals. The second weight is the ratio of the second occurrence times of a single target negative pressure interval corresponding to the target speed interval to the sum of the second occurrence times of all corresponding target negative pressure intervals; Based on the actual drainage speed, the actual negative pressure magnitude, the first weight, and the second weight, determine whether there is a risk of blockage of the negative pressure drainage tube for the target patient.

[0008] By adopting the above technical solution, the larger the first occurrence times, the more likely it is that wound infection occurs when the negative pressure drainage speed is in the corresponding historical speed interval, and then the target speed interval is determined. The larger the second occurrence times, the more likely it is that the drainage tube is blocked and wound infection is caused when the negative pressure is in the corresponding historical negative pressure interval. Finally, by combining the first weight and the second weight, analyze the likelihood of wound infection caused by blockage for the target patient under the actual drainage speed and the actual negative pressure magnitude, so as to more accurately determine whether there is a risk of blockage of the negative pressure drainage tube for the target patient.

[0009] Optionally, the determining whether there is a risk of blockage of the negative pressure drainage tube for the target patient based on the actual drainage speed, the actual negative pressure magnitude, the first weight, and the second weight specifically includes: If the actual drainage speed is within the target speed interval, determine the corresponding target speed interval as the key speed interval, and determine the target negative pressure interval where the actual negative pressure magnitude is located as the important negative pressure interval; If the important negative pressure interval exists among the target negative pressure intervals corresponding to the key speed interval, determine the corresponding key speed interval as the important speed interval, and calculate the first product of the first weight of the important speed interval and the second weight of the corresponding important negative pressure interval; Compare the first product with a preset first threshold. If the first product exceeds the first threshold, determine that there is a risk of blockage of the negative pressure drainage tube for the target patient.

[0010] By adopting the above technical solution, the larger the first product, the greater the likelihood that the target patient has a blockage of the negative pressure drainage tube and causes wound infection under the current actual drainage speed and actual negative pressure magnitude. Finally, if the first product exceeds the first threshold, then it is determined that the likelihood of blockage of the negative pressure drainage tube and causing wound infection is relatively large, so as to more accurately determine whether there is a risk of blockage of the negative pressure drainage tube for the target patient currently.

[0011] Optionally, the determining the target flushing speed for flushing the negative pressure drainage tube specifically includes: Calculate the second product of the first weight of each of the target speed intervals and the second weight of the corresponding target negative pressure intervals; Summarize the target negative pressure intervals that have intersections with each other into a set of negative pressure intervals, sum up the second products corresponding to the target negative pressure intervals in the set of negative pressure intervals, and obtain the corresponding sum of the first products; Select the minimum sum of the first products from the sums of the first products, determine the set of reference intervals corresponding to the minimum sum of the first products, and determine the appropriate negative pressure magnitude based on the intersection of the target negative pressure intervals in the set of reference intervals; Adjust the actual negative pressure magnitude to the appropriate negative pressure magnitude, and determine the target flushing speed for flushing the negative pressure drainage tube based on the appropriate negative pressure magnitude.

[0012] By adopting the above technical solution, the larger the sum of the first products, when the set negative pressure is within the intersection of each target negative pressure interval in the corresponding set of negative pressure intervals, the greater the overall possibility of wound infection caused by blockage of the negative pressure drainage tube. Then, adjust the actual negative pressure magnitude to this appropriate negative pressure magnitude, thereby reducing the risk of subsequent blockage and infection.

[0013] Optionally, the determining the target flushing speed for flushing the negative pressure drainage tube based on the appropriate negative pressure magnitude specifically includes: Obtain the historical flushing speeds that did not interfere with the negative pressure during the historical flushing of the negative pressure drainage tube, count the first occurrence frequencies of each of the historical flushing speeds, and select the third number of historical flushing speeds from the historical flushing speeds in descending order of the first occurrence frequencies to determine the key flushing speeds; Obtain the negative pressure interval where the set negative pressure is located when a single key flushing speed does not interfere with the negative pressure, count the second occurrence frequencies of each of the negative pressure intervals, and select the fourth number of negative pressure intervals from the negative pressure intervals in descending order of the second occurrence frequencies to determine the key negative pressure intervals corresponding to a single key flushing speed; Determine the third weight of each of the key flushing speeds, and determine the fourth weight of the key negative pressure intervals corresponding to each of the key flushing speeds. The third weight is the ratio of the first occurrence frequency of each key flushing speed to the sum of the first occurrence frequencies of all key flushing speeds, and the fourth weight is the ratio of the second occurrence frequency of a single key negative pressure interval corresponding to a key flushing speed to the sum of the second occurrence frequencies of the corresponding all key negative pressure intervals; Determine the target flushing speed for flushing the negative pressure drainage tube based on the appropriate negative pressure magnitude, the third weight, and the fourth weight.

[0014] By adopting the above technical solution, the greater the first occurrence frequency, the less likely it is to interfere with the negative pressure environment of the wound surface when flushing the negative pressure drainage tube at the corresponding historical flushing speed, and then the key flushing speed is determined; the greater the second occurrence frequency, the less likely it is to interfere with the negative pressure when flushing at a single key flushing speed and the set negative pressure is within the corresponding negative pressure range, and then the key negative pressure range is determined. Finally, by combining the third weight and the fourth weight, the flushing speed with less interference to the negative pressure is analyzed, so as to ensure the effect of negative pressure drainage.

[0015] Optionally, determining the target flushing speed for flushing the negative pressure drainage tube based on the appropriate negative pressure magnitude, the third weight, and the fourth weight specifically includes: If the appropriate negative pressure magnitude is within the key negative pressure range, then determine the corresponding key negative pressure range as the final negative pressure range. When the final negative pressure range exists among the key negative pressure ranges corresponding to the key flushing speed, determine the corresponding key flushing speed as the final flushing speed; Calculate the third product of the third weight of each of the final flushing speeds and the fourth weight of the corresponding final negative pressure range; Select the maximum third product from each of the third products, and determine the final flushing speed corresponding to the maximum third product as the target flushing speed.

[0016] By adopting the above technical solution, the greater the third product, the less likely it is to interfere with the negative pressure when flushing the drainage tube at the corresponding final flushing speed under this appropriate negative pressure magnitude. Finally, select the maximum third product from each of the third products, and determine the final flushing speed corresponding to this maximum third product as the target flushing speed. When flushing the drainage tube at this target flushing speed subsequently, the possibility of interfering with the negative pressure is the smallest, and at the same time, it can better reduce the risk of wound infection caused by blockage of the negative pressure drainage tube.

[0017] Optionally, the method further includes: When the actual drainage speed is within the corresponding normal speed range, determine the target speed range within the normal speed range as the reference speed range, and determine the target negative pressure range where the actual negative pressure magnitude is located as the reference negative pressure range; Calculate the fourth product of the first weight of each of the reference speed ranges and the second weight of the corresponding reference negative pressure range, and sum each of the fourth products to obtain the sum of the second products; If the sum of the second products is less than a preset second threshold, determine that the target patient has a risk of wound infection and issue a warning for the wound infection.

[0018] By adopting the above technical solution, the larger the sum of the second products is, the greater the possibility that wound infection is caused by the blockage of the negative pressure drainage tube when the negative pressure drainage speed is carried out according to the actual negative pressure magnitude under normal circumstances; if the sum of the second products is less than a preset second threshold value, the possibility that wound infection is caused by the blockage of the negative pressure drainage tube is relatively small, and it is very likely that the injured wound itself is infected, then a warning message is sent, so as to realize the timely warning of wound infection.

[0019] In the second aspect of the present application, a cleaning control device for a negative pressure drainage tube is provided, which specifically includes: An information acquisition module, configured to acquire the actual drainage speed and the actual negative pressure magnitude of the current negative pressure drainage tube of the target patient; A risk determination module, configured to determine whether there is a risk of blockage of the negative pressure drainage tube for the target patient based on the actual drainage speed, the actual negative pressure magnitude, the target speed range of historical patients, and at least one corresponding target negative pressure range when the actual drainage speed is not within the corresponding normal speed range. The target speed range is the speed range in which the negative pressure drainage speed is likely to be when wound infection occurs in historical patients, and the target negative pressure range is the negative pressure range in which the set negative pressure magnitude is likely to be when wound infection occurs in historical patients and the inducing factor is blockage of the drainage tube. The historical patients and the target patient are identical in terms of patient portraits and wound types; A speed determination module, configured to, if so, determine the target flushing speed for flushing the negative pressure drainage tube; A concentration determination module, configured to determine the risk coefficient of wound infection of the target patient, and determine the target drug concentration of the anti-infection drug in the flushing solution when flushing the negative pressure drainage tube based on the risk coefficient; A drainage flushing module, configured to flush the negative pressure drainage tube according to the target flushing speed and the target drug concentration.

[0020] By adopting the above technical solution, after the information acquisition module acquires the actual drainage speed and the actual negative pressure magnitude, the risk determination module determines whether there is a risk of blockage of the negative pressure drainage tube for the target patient. Then, when there is a risk of blockage of the negative pressure drainage tube, the speed determination module determines the target flushing speed. Then, the concentration determination module determines the target drug concentration based on the risk coefficient. Finally, the drainage flushing module flushes the negative pressure drainage tube at the target flushing speed and the target drug concentration.

[0021] 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.

[0022] In a fourth aspect of the present application, an electronic device is provided, specifically including: a processor, a memory, and a computer program stored in the memory and capable of running on the processor, where the processor is used 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.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: If the actual drainage speed is not within the corresponding normal speed range, it indicates that the current drainage speed is slow, and there may be a risk of blockage of the negative pressure drainage tube, which needs to be further verified. Then, based on the target speed range and the corresponding target negative pressure range, analyze the likelihood of wound infection caused by blockage in the target patient under the actual drainage speed and actual negative pressure magnitude, and then more accurately determine whether the target patient has a blockage risk. If there is a blockage risk, then specifically determine the target flushing speed for flushing, and reasonably determine the target drug concentration of the anti-infection drug in the flushing solution according to the risk coefficient of wound infection of the target patient. By monitoring the blockage risk in a timely manner, once the negative pressure drainage tube is indeed blocked, flushing can be carried out in a timely manner with this target flushing speed and target drug concentration, and the flushing effect is better. Avoid flushing after a real blockage occurs, as the flushing effect is poor. Description of the Drawings

[0029] See Figure 1 , the embodiments of the present application disclose a schematic flow chart of a cleaning control method for a negative pressure drainage tube, which can be implemented depending on a computer program or run on a cleaning control device for a negative pressure drainage tube based on the von Neumann architecture. This computer program can be integrated into an application or run as an independent tool-type application, and specifically includes: S101: Obtain the actual drainage speed and actual negative pressure magnitude of the current negative pressure drainage tube of the target patient.

[0030] Specifically, in the embodiments of the present application, the target patient is a patient undergoing negative pressure drainage for an injured wound surface, where the injured wound surface is an acute traumatic wound surface, such as a burn wound surface. In other embodiments, the injured wound surface can also be a postoperative wound surface, etc. Performing negative pressure drainage on the injured wound surface means applying negative pressure on the injured wound surface to promote blood circulation of the injured wound surface, accelerate the discharge of exudates, and improve the speed and quality of wound healing. The negative pressure drainage tube used by the target patient during negative pressure drainage is a double-lumen drainage tube, which includes two cavities, namely a drainage cavity and a flushing cavity. The drainage cavity is used to extract the exudates of the injured wound surface under the negative pressure environment created by the negative pressure drainage device. The flushing cavity is connected to a flushing fluid supply device and is used to keep the negative pressure drainage tube unobstructed during drainage and clean the injured wound surface, etc.

[0031] The execution subject of the cleaning control method of the negative pressure drainage tube disclosed in the embodiments of the present application is a server, which is wirelessly connected to the negative pressure drainage device and the flushing fluid supply device. Exemplarily, in this connection state, the server can remotely monitor the operating state of the flushing fluid supply device, adjust the flushing parameters, etc. The server can be an independent physical server or a server cluster composed of multiple physical servers. The server is also wirelessly connected to an ultrasonic flow rate sensor preset in the negative pressure drainage tube. Further, the actual drainage speed of the current negative pressure drainage tube of the target patient can be obtained through the ultrasonic flow rate sensor. In addition, the set negative pressure magnitude is obtained through the negative pressure drainage device, and then the actual negative pressure magnitude is determined.

[0032] S102: When the actual drainage speed is not within the corresponding normal speed range, based on the actual drainage speed, the actual negative pressure magnitude, the target speed range of the historical patient, and the corresponding at least one target negative pressure range, determine whether there is a risk of blockage of the negative pressure drainage tube for the target patient.

[0033] Specifically, the target speed range is the speed range in which the negative pressure drainage speed is likely to be when the historical patient has a wound infection, and the target negative pressure range is the negative pressure range in which the set negative pressure magnitude is likely to be when the historical patient has a wound infection and the inducement is blockage of the drainage tube. Among them, the historical patient and the target patient are the same in terms of patient portrait and wound type. The patient portrait is a user model established based on the patient's gender, age, and physical health status. The wound type characterizes the patient's wound category, wound location, wound depth, etc. In addition, when the negative pressure drainage tube is blocked, the exudate cannot be effectively drained out of the body, resulting in the accumulation of exudate in the injured wound. This accumulation provides an environment for bacteria to multiply and increases the risk of infection.

[0034] Further, it is judged whether this actual drainage speed is within the corresponding normal speed range, where the normal speed range is the drainage speed range when the exudate is normally discharged through the drainage tube under the actual negative pressure magnitude. If the actual drainage speed is not within the normal speed range, it means that the current drainage speed is slow and there may be a risk of blockage of the negative pressure drainage tube. Then, based on the historical monitoring record of wound surface negative pressure drainage, obtain the historical speed range in which the negative pressure drainage speed is located when the historical patient has a wound infection, and count the first occurrence times of each historical speed range. The larger the first occurrence times, the easier it is for the negative pressure drainage speed to have a wound infection in the corresponding historical speed range. Then, in the order from largest to smallest of the first occurrence times, select the first number of historical speed ranges from each historical speed range and determine them as the target speed range. It should be noted that the historical monitoring record includes but is not limited to the negative pressure drainage speed, the set negative pressure situation, and the infection inducement of different historical wound surface patients who have had wound infections.

[0035] Furthermore, based on the above historical monitoring records, when the historical patients had wound infections and the cause was the blockage of the negative pressure drainage tube, and the negative pressure drainage speed was within a single target speed range, the historical negative pressure range where the set negative pressure magnitude was located was obtained. The second occurrence frequency of each historical negative pressure range was counted. The greater the second occurrence frequency, the more likely it was for the drainage tube to be blocked and cause wound infection when the negative pressure was within the corresponding historical negative pressure range. Then, in the order from largest to smallest of the second occurrence frequencies, the second number of historical negative pressure ranges was selected from each historical negative pressure range and determined as the target negative pressure range corresponding to the target speed range.

[0036] Next, the first weight of each target speed range was determined. The first weight was the ratio of the first occurrence frequency of each target speed range to the sum of the first occurrence frequencies of all target speed ranges. Then, the second weight of the target negative pressure range corresponding to each target speed range was determined. The second weight was the ratio of the second occurrence frequency of the single target negative pressure range corresponding to the target speed range to the sum of the second occurrence frequencies of all the corresponding target negative pressure ranges. Finally, in combination with the determined first weight and second weight, it was further determined whether the target patient had a risk of negative pressure drainage tube blockage. One achievable implementation method was as follows: If the actual drainage speed was within the target speed range, then the corresponding target speed range was determined as the key speed range. At the same time, the target negative pressure range where the actual negative pressure magnitude was located was determined as the important negative pressure range. Then, if there was an important negative pressure range among the target negative pressure ranges corresponding to the key speed range, then the corresponding key speed range was determined as the important speed range. Calculate the first product of the first weight of this important speed range and the second weight of the corresponding important negative pressure range. The larger the first product, the greater the possibility that the target patient would have a negative pressure drainage tube blockage and cause wound infection under the current actual drainage speed and actual negative pressure magnitude. Finally, if the first product exceeded the first threshold, then it was determined that the possibility of a negative pressure drainage tube blockage and causing wound infection was relatively large, and then it was determined that the target patient had a risk of negative pressure drainage tube blockage.

[0037] S103: If so, determine the target flushing speed for flushing the negative pressure drainage tube.

[0038] Specifically, if it is determined that the target patient has a risk of negative pressure drainage tube blockage and flushing needs to be performed through the flushing cavity, then it is necessary to determine the target flushing speed for flushing, so as to reduce the risk of blockage or quickly solve the blockage problem. In the embodiments of the present application, a feasible determination method is as follows: calculate the second product of the first weight of each target speed interval and the second weight of the corresponding target negative pressure intervals, then use the MATLAB tool to determine whether there is an intersection between the target negative pressure intervals, and then summarize the target negative pressure intervals with intersections with each other into a negative pressure interval set. Sum the second products corresponding to the target negative pressure intervals in the negative pressure interval set to obtain the sum of the first products of the corresponding negative pressure interval set. The larger the sum of the first products, the greater the overall possibility of wound infection caused by negative pressure drainage tube blockage when the set negative pressure is within the intersection of the target negative pressure intervals in the corresponding negative pressure interval set. Further, select the smallest sum of the first products from each sum of the first products, determine the negative pressure interval set corresponding to the smallest sum of the first products as the reference interval set, find the intersection of the target negative pressure intervals in the reference interval set, and determine the appropriate negative pressure magnitude according to the intersection. Specifically, the maximum value in the intersection can be selected as the appropriate negative pressure magnitude. Then, adjust the actual negative pressure magnitude to this appropriate negative pressure magnitude through the negative pressure drainage device, so as to reduce the risk of subsequent blockage and infection.

[0039] Finally, based on this appropriate negative pressure magnitude, determine the target flushing speed. A feasible implementation method is as follows: based on the historical flushing records, obtain the historical flushing speeds that did not interfere with the negative pressure during the historical flushing of the negative pressure drainage tube, and count the first occurrence frequency of each historical flushing speed. The greater the first occurrence frequency, the less likely it is to interfere with the negative pressure environment of the wound when flushing the negative pressure drainage tube at the corresponding historical flushing speed. Select the third number of historical flushing speeds from each historical flushing speed in descending order of the first occurrence frequency as the key flushing speeds, that is, the flushing speeds that are not likely to interfere with the negative pressure and affect the negative pressure drainage effect. Among them, the historical flushing records include but are not limited to different flushing speeds and corresponding negative pressure magnitudes of past flushes that did not interfere with the negative pressure.

[0040] Based on the above historical flushing records, obtain the negative pressure interval where the set negative pressure is located when a single key flushing speed does not interfere with the negative pressure, and count the second occurrence frequency of each negative pressure interval. The greater the second occurrence frequency, the less likely it is to interfere with the negative pressure when flushing at a single key flushing speed and the set negative pressure is within the corresponding negative pressure interval. Then, select the fourth number of negative pressure intervals from each negative pressure interval in descending order of the second occurrence frequency as the key negative pressure intervals corresponding to this key flushing speed, that is, the negative pressure intervals that are not easily interfered with.

[0041] Further, determine the third weight for each key flushing speed and determine the fourth weight for the key negative pressure range corresponding to each key flushing speed. Among them, the third weight is the ratio of the first occurrence frequency of each key flushing speed to the sum of the first occurrence frequencies of all key flushing speeds. The fourth weight is the ratio of the second occurrence frequency of a single key negative pressure range corresponding to the key flushing speed to the sum of the second occurrence frequencies of all corresponding key negative pressure ranges.

[0042] Further, if the appropriate negative pressure magnitude is within the key negative pressure range, then determine the corresponding key negative pressure range as the final negative pressure range. At the same time, if this final negative pressure range exists among the key negative pressure ranges corresponding to the key flushing speed, then determine the corresponding key flushing speed as the final flushing speed. Then calculate the third product of the third weight of each final flushing speed and the fourth weight of the corresponding final negative pressure range. The larger the third product, the smaller the possibility of negative pressure interference when flushing the drainage tube at the corresponding final flushing speed under this appropriate negative pressure magnitude. Finally, select the largest third product from each third product, and determine the final flushing speed corresponding to this largest third product as the target flushing speed. Subsequently, flushing the drainage tube at this target flushing speed has the smallest possibility of negative pressure interference and can better reduce the risk of wound infection caused by blockage of the negative pressure drainage tube. In other embodiments, since the larger the first product, the greater the possibility of wound infection caused by blockage, which further indicates that the degree of blockage of the negative pressure drainage tube may be greater, and a greater flushing speed is required to better flush the drainage tube and make it unobstructed. Match the corresponding flushing speed range from the preset speed matching table according to the first product. The speed matching table includes different first products and the corresponding flushing speed ranges, all of which are set based on human experience. Further, if the final flushing speed corresponding to the largest third product is within this flushing speed range, then it is determined as the target flushing speed; if it is not within this flushing speed range, then select the smallest flushing speed from the flushing speed range. If the smallest flushing speed is the final flushing speed, then when the third product corresponding to the smallest flushing speed is greater than the preset threshold, determine this smallest flushing speed as the target flushing speed.

[0043] If the smallest flushing speed is not the final flushing speed, then determine the final flushing speed greater than the smallest flushing speed as the first flushing speed, and determine the final flushing speed less than the smallest flushing speed as the second flushing speed. If the third products corresponding to the first flushing speed and the second flushing speed are both greater than the preset threshold, then flushing at this smallest flushing speed has a smaller possibility of negative pressure interference, so determine it as the target flushing speed.

[0044] In another embodiment, if the actual drainage rate is within the corresponding normal rate range, it indicates that at the actual negative pressure magnitude, this actual drainage rate is normal and the probability of blockage of the negative pressure drainage tube is relatively low. Then, the target rate range within the normal rate range is determined as the reference rate range, and the target negative pressure range where the actual negative pressure magnitude is located is determined as the reference negative pressure range. Next, calculate the fourth product of the first weight of each reference rate range and the second weight of the corresponding reference negative pressure range, sum up the respective fourth products to obtain the sum of the second products. The larger the sum of the second products, the greater the probability that wound infection is caused by blockage of the negative pressure drainage tube when performing negative pressure drainage at the actual negative pressure magnitude under normal negative pressure drainage rates; if the sum of the second products is less than a preset second threshold, the probability that wound infection is caused by blockage of the negative pressure drainage tube is relatively small, and it is highly probable that the injured wound itself is infected. Then, a warning message of wound infection is sent to the doctor's terminal, notifying the doctor to go and check in time. The terminal can be a smart phone or a personal computer. At the same time, it is also verified that the normal rate range corresponding to the actual drainage rate is correct.

[0045] S104: Determine the risk coefficient of wound infection of the target patient, and based on the risk coefficient, determine the target drug concentration of the anti-infection drug in the flushing solution when flushing the negative pressure drainage tube.

[0046] Specifically, in the embodiment of the present application, the first product is determined as the risk coefficient of wound infection of the target patient. The larger the risk coefficient, the greater the probability of wound infection. Then, according to this risk coefficient, the corresponding target drug concentration is matched from a preset concentration matching table. The larger the risk coefficient, the greater the corresponding target drug concentration. The concentration matching table includes different risk coefficients and the corresponding drug concentrations, all of which are set based on human experience. In other embodiments, the first product is determined as the first risk coefficient of wound infection of the target patient, and at least one negative pressure setting magnitude and the corresponding normal rate range at normal drainage rates from the start of negative pressure drainage to the current time are obtained. The target rate range within a single normal rate range is determined as the rate range to be analyzed, and the target negative pressure range where the negative pressure setting magnitude is located is determined as the negative pressure range to be analyzed. Calculate the product of the first weight of each rate range to be analyzed and the second weight of the corresponding negative pressure range to be analyzed and sum them up to obtain the sum of the products corresponding to a single negative pressure setting magnitude. Sum up the respective sums of the products to obtain the final sum of the products. The smaller the final sum of the products, the greater the probability that wound infection is caused by non-blockage reasons. Then, this final sum of the products is determined as the second risk coefficient. Finally, the first risk coefficient and the second risk coefficient are summed up to obtain the risk coefficient of wound infection of the target patient, so as to more accurately determine the target drug concentration based on this.

[0047] S105: Flush the negative pressure drainage tube according to the target flushing rate and the target drug concentration.

[0048] Specifically, after determining the target flushing speed and the target drug concentration, a corresponding flushing parameter adjustment instruction is sent to the flushing fluid supply device, so that the flushing fluid supply device flushes the negative pressure drainage tube at this target flushing speed and the target drug concentration. Once there is a blockage and wound infection, not only can the blockage be flushed, but also the wound can be cleaned to ensure the normal healing of the wound.

[0049] The implementation principle of the cleaning control method for the negative pressure drainage tube in the embodiment of the present application is as follows: If the actual drainage speed is not within the corresponding normal speed range, it means that the current drainage speed is slow, and there may be a risk of blockage of the negative pressure drainage tube, which needs to be further verified. Then, based on the target speed range and the corresponding target negative pressure range, analyze the possibility of wound infection caused by blockage under the actual drainage speed and the actual negative pressure of the target patient, and then more accurately determine whether there is a blockage risk for the target patient. If there is a blockage risk, then specifically determine the target flushing speed for flushing, and reasonably determine the target drug concentration of the anti-infection drug in the flushing fluid according to the risk coefficient of wound infection of the target patient. By timely monitoring the blockage risk, once the negative pressure drainage tube is indeed blocked, it can be flushed in time at this target flushing speed and the target drug concentration, and the flushing effect is better. Avoid flushing after a real blockage occurs, as the flushing effect is poor.
