Description

Technical Field

[0001] The present invention relates to the technical field of abdominal drainage control, and specifically to an abdominal drainage control system for digestive care internal medicine. Background Art

[0002] Abdominal drainage is a common surgical procedure aimed at removing accumulated fluid, blood, and other harmful substances in the abdominal cavity to reduce intra-abdominal pressure, prevent infection, and promote wound healing. This technique plays an important role in the diagnosis and treatment of digestive system diseases. The principle of its abdominal drainage control system is to drain the accumulated fluid in the abdominal cavity to the outside through a drainage tube, reduce the accumulation of fluid in the abdominal cavity, and utilize the principles of negative pressure and gravity to make the fluid in the abdominal cavity flow out continuously or intermittently. During this period, various data in the drainage process, including drainage rate and drainage efficiency, need to be monitored in real time to ensure the drainage effect.

[0003] However, existing abdominal drainage control systems often rely on medical staff to manually adjust input fluid volume and time interval parameters, lacking intelligent and automated adjustment mechanisms. This leads to untimely and inaccurate parameter adjustment, thereby affecting the drainage effect and patient safety. Moreover, some systems lack a comprehensive assessment of system stability and cannot monitor and warn potential instability factors in real time. Among them, if the system stability is poor, it will lead to problems such as unsmooth drainage and pipeline blockage, thus increasing the risk and discomfort of patients. In addition, when some systems evaluate drainage efficiency, they do not fully consider the impact of lost fluid volume on efficiency, resulting in inaccurate evaluation results. This will cause medical staff to misjudge the drainage effect and thus affect subsequent treatment plans. Furthermore, existing systems often lack a closed-loop feedback mechanism and cannot automatically adjust parameters based on real-time monitored data to improve the drainage effect and system stability, which limits the adaptive ability and intelligent level of the system. Summary of the Invention

[0004] The purpose of the present invention is to provide an abdominal drainage control system for digestive care internal medicine, solving the problems raised in the above background art.

[0006] Optionally, the devices used by the data acquisition module include an abdominal cavity drainage tube, a liquid metering device, and a time controller; The devices used by the data calculation module include a data processing and calculation system; The devices used by the system warning module include a data control system; The devices used by the adjustment control module include an alarm device.

[0007] Optionally, the calculation formula of the unit for timely understanding the current drainage situation of the patient is as follows: LS = SQRT(YV in - YV out ) / T; Where: LS is the drainage rate; YV in is the input abdominal cavity fluid volume; YV out is the drained fluid volume; T is the time interval, and T reflects the time difference between the input abdominal cavity fluid volume YV in and the drained fluid volume YV out .

[0008] Optionally, the calculation formula of the unit for evaluating the effectiveness of the drainage strategy is as follows: YX = (LS × T) / YV in - (YV lose / YV in ) × (1 - LS / LS max ); Wherein: YX is the drainage efficiency; YV lose is the volume of drained liquid lost, and YV lose reflects the volume of liquid lost by the patient during drainage; LS max is the maximum drainage rate, and LS max reflects the fastest degree of the drainage rate LS stored in the control system.

[0009] Optionally, the volume of drained liquid YV out does not include the volume of drained liquid lost YV lose , and the volume of drained liquid lost YV lose represents the volume of liquid lost due to reasons including pipeline leakage and system errors during drainage. This part of the liquid is not drained as expected, but is an additional loss due to system imperfections and external factors. The volume of drained liquid YV out represents the actual volume of liquid drained from the abdominal cavity, which is the result of the normal operation of the control system and reflects the drainage capacity of the control system without loss.

[0010] Optionally, the calculation formula for the unit evaluating the overall stability of the abdominal drainage control system is as follows: W = (YX × (LS - LS old ) / LS) - SQRT((YX old - YX) 2 ); Wherein: W is the system stability index, and its value range is from negative to positive, and the closer it is to 0, the more stable; LS old is the drainage rate before adjustment; YX old is the drainage efficiency before adjustment; △T is the adjustment time difference, and △T reflects the time difference between the previous adjustment of the patient's drainage and the start of the current drainage.

[0011] Optionally, the calculation formula for the adjustment time difference △T is as follows: △T = T new - T old ; T new is the start time of the current drainage; Told is the end time of the previous drainage.

[0012] Optionally, the control adjustment based on the system stability index W is as follows: If the result value of the system stability index W is far from 0, and the drained lost liquid volume YV lose has increased compared to the previous drainage, it reflects that there are problems with the control system, including pipeline blockage and poor drainage. The input abdominal cavity liquid volume YV should be reduced during the next drainage in ; If the result value of the system stability index W is far from 0, and the drained lost liquid volume YV lose has decreased compared to the previous drainage, it reflects that the drainage efficiency YX of the control system has improved, but the stability is poor. It should be judged according to the positive and negative values of the result value of the system stability index W, as follows: If the result value of the system stability index W is positive, it reflects that the control system is too sensitive and responds too quickly. The time interval T should be increased to slow down the change speed of the control system; If the result value of the system stability index W is negative, it reflects that there are problems of insufficient response and being too slow in the control system. The time interval T should be reduced to speed up the response speed of the control system; If the result value of the system stability index W is equal to 0, it is considered that the control system drains normally and stably.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by introducing an intelligent algorithm and a feedback mechanism for early warning adjustment, the control system of the present invention can monitor various data during the drainage process in real time, and automatically adjust the abdominal cavity liquid volume YV in and the time interval T parameter according to the calculation results of the unit for timely understanding of the current drainage situation of the patient, the unit for evaluating the effectiveness of the drainage strategy, and the unit for evaluating the overall stability of the abdominal cavity drainage control system.

[0015] Third, the present invention fully considers the influence of the drained lost liquid volume YV lose on the drainage efficiency YX, and accurately evaluates it using the unit for evaluating the effectiveness of the drainage strategy. This helps to more accurately understand the drainage effect and then formulate a more reasonable treatment plan.

[0016] IV. The control system of the present invention forms a closed-loop feedback mechanism, which can automatically adjust parameters according to the real-time monitored data and calculation results. This mechanism not only improves the adaptive ability and intelligent level of the system, but also ensures the continuity and stability of the drainage process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Regarding the abdominal drainage control system for this department of digestive care medicine, different from the existing abdominal drainage control system for digestive care medicine, the existing abdominal drainage control system for digestive care medicine not only lacks an intelligent and automated adjustment mechanism, but also lacks a comprehensive evaluation of system stability, and thus lacks a closed-loop feedback mechanism and cannot automatically adjust parameters according to the real-time monitored data to improve the drainage effect and system stability. In addition, the influence of the lost liquid volume on the efficiency is not fully considered during the drainage process. However, through the innovative control management of introducing intelligent algorithms, comprehensive system stability evaluation, accurate drainage efficiency evaluation and closed-loop feedback mechanism, this algorithm unit effectively solves the problems and deficiencies existing in the prior art. These optimizations and innovations not only improve the performance and intelligent level of the system, but also provide a more reliable and accurate monitoring and management tool, which helps to improve the treatment effect and safety of patients.

[0020] Example 1, please refer to Figures 1 to 4, this implementation provides a digestive care internal medicine abdominal drainage control system, and the specific implementation steps are as follows: Step 1: Use the data acquisition module to collect the volume of abdominal cavity fluid YV input for abdominal drainage of the patient in , the volume of drained fluid YV out , time interval T, the volume of drained fluid loss YV lose , maximum drainage rate LS max , drainage rate LS before adjustment old , drainage efficiency YX before adjustment old , adjustment time difference △T; Step 2: Use the data calculation module and based on the volume of abdominal cavity fluid YV in , the volume of drained fluid YV out and time interval T, first calculate and output the current drainage rate LS of the patient; Then based on the drainage rate LS, time interval T, the volume of drained fluid loss YV lose , maximum drainage rate LS max , calculate and output the drainage efficiency YX; Finally, based on the drainage efficiency YX, drainage rate LS, drainage rate LS before adjustment old , drainage efficiency YX before adjustment old and adjustment time difference △T, calculate and output the system stability index W; Among them, the data calculation module includes a unit for timely understanding of the current drainage situation of the patient, a unit for evaluating the effectiveness of the drainage strategy, and a unit for evaluating the overall stability of the abdominal drainage control system; Step 3: Based on the system stability index W and use the system warning module to give a warning about the current abdominal drainage; Step 4: According to the warning result and use the adjustment control module to control and adjust the abdominal drainage by the control system; The devices used by the data acquisition module include an abdominal drainage tube, a liquid metering device, and a time controller; The devices used by the data calculation module include a data processing and calculation system; The devices used by the system warning module include a data control system; The devices used by the adjustment control module include an alarm device.

[0021] In this embodiment, the system constructs a complete abdominal drainage control system for digestive care internal medicine through the mutual cooperation of three algorithm units and in combination with the calculation results of LS, YX, and W. Specifically, it realizes the accurate calculation of the drainage rate LS, the evaluation of the drainage efficiency YX, and the real-time monitoring and optimization of the system stability. Specifically, LS is the drainage rate, and this value can timely understand the patient's drainage situation, judge whether there are other potential problems such as unsmooth drainage or blockage, and provide a basis for adjusting parameters to ensure that the drainage rate LS is maintained within an appropriate range. YX is the drainage efficiency, and this value is an important indicator for evaluating the effect of the drainage process, which helps to understand the effectiveness of the drainage strategy and optimize it accordingly. W is the system stability index, which is used to evaluate the overall stability of the abdominal drainage control system, and system stability is crucial for ensuring the continuity and safety of the drainage process. By calculating W, it is possible to determine whether there are unstable factors in the system and take timely measures for intervention. Moreover, the calculation result of W can also affect the calculations of LS and YX, making the three algorithms of this system interrelated and influencing each other, and thus jointly constituting the core algorithm framework of the abdominal drainage control system for digestive care internal medicine, and providing comprehensive, accurate, real-time monitoring and evaluation means as well as a basis for optimization and adjustment.

[0022] Please refer to Figures 1 to 4 , the calculation formula for the unit to timely understand the patient's current drainage situation is as follows: LS = SQRT(YV in - YV out ) / T; Where: LS is the drainage rate; YV in is the volume of fluid input into the abdominal cavity; YV out is the volume of fluid drained out; T is the time interval, and T reflects the time difference for drainage between the volume of fluid YV in input into the abdominal cavity and the volume of fluid YV out drained out.

[0023] In this embodiment: First, in this algorithm unit, the calculation part of "SQRT(YV in - YV out ) / T" calculates the square root of the difference between the volume of fluid input into the abdominal cavity and the volume of fluid drained out per unit time, and divides it by the time interval T to obtain the drainage rate LS. And the drainage rate LS is a key indicator for evaluating the performance of the abdominal drainage system. It reflects how much fluid the system can handle within a certain period of time. By calculating this value, it is possible to understand the drainage capacity of the system and provide a basis for subsequent parameter adjustment. As the core calculation part of the unit to timely understand the patient's current drainage situation, it directly determines the magnitude of the drainage rate LS; The drainage rate LS of this algorithm will serve as an important input parameter for the unit evaluating the effectiveness of the drainage strategy and the unit evaluating the overall stability of the abdominal drainage control system, affecting the evaluation and stability analysis of the entire system; The drainage rate LS in the unit for timely understanding of the patient's current drainage situation in this algorithm is calculated in real time and depends on the input abdominal fluid volume YV in , the drained fluid volume YV out , and the time interval T. This means that the control system can immediately understand the change in the drainage rate LS and thus quickly respond to any abnormal situation; There is a close relationship between the parameters in the unit for timely understanding of the patient's current drainage situation and the drainage rate LS. Specifically, increasing the input abdominal fluid volume YV in and extending the time interval T will both result in an increase in the drainage rate LS, while the drained fluid volume YV out will result in a decrease in the drainage rate LS. This parameter correlation will provide a basis for optimizing the drainage process.

[0024] Please refer to Figures 1 to 4 , the calculation formula for the unit evaluating the effectiveness of the drainage strategy is as follows: YX = (LS × T) / YV in - (YV lose / YV in ) × (1 - LS / LS max ); Where: YX is the drainage efficiency; YV lose is the drained fluid volume lost, and YV lose reflects the fluid volume lost by the patient during the drainage process; LS max is the maximum drainage rate, and LS max reflects the fastest degree of the drainage rate LS stored in the control system.

[0025] In this embodiment, first, the calculation part of "(LS × T) / YV in " actually calculates the ratio of the product of the input abdominal fluid volume YV in entering the abdomen, the drainage rate LS, and the time interval T, that is, the ratio of the input volume to the drained volume per unit time. This calculation part reflects the utilization rate of the input fluid by the system, that is, what proportion of the input fluid is successfully drained. As a component of the calculation of the unit evaluating the effectiveness of the drainage strategy, it is used to evaluate the drainage efficiency YX of the system. When this ratio is high, it indicates that the system has a high utilization rate of the input fluid and good drainage effect; "(YV lose / YV in)×(1 - LS / LS max )” The calculation part calculates the volume of the drained liquid loss YV during the drainage process. lose与 The volume of the liquid input into the abdominal cavity YV in ratio, and multiplies it by a factor related to the drainage rate LS and the maximum drainage rate LS max This calculation part reflects the proportion of the liquid lost by the system during the drainage process and the relationship between this loss and the drainage rate LS. As another key component calculated by the unit for evaluating the effectiveness of the drainage strategy, it is used to evaluate the loss situation of the system during the drainage process. When this calculation part is large, it indicates that the system has more losses and the drainage efficiency YX decreases. This algorithm comprehensively considers the volume of the liquid input into the abdominal cavity, the drainage rate LS, the volume of the drained liquid loss YV lose and the maximum drainage rate LS of the system max by the unit for evaluating the effectiveness of the drainage strategy, and can accurately calculate the drainage efficiency YX. This accurate evaluation provides a direct indicator of the efficiency of the drainage process and helps to understand whether the drainage process is efficient. By evaluating the drainage efficiency YX, the bottlenecks and deficiencies in the drainage process can be discovered. For example, if the drainage efficiency YX is low, it is due to the excessive volume of the drained liquid loss YV lose or the too low drainage rate LS. Thus, the drainage strategy can be adjusted based on these findings to improve the drainage efficiency. The evaluation result of the drainage efficiency YX can also be used as a feedback signal to adjust the parameters in the unit for timely understanding the current drainage situation of the patient, thereby further improving the drainage efficiency YX. This feedback adjustment mechanism helps to form a closed-loop feedback system and continuously optimize the drainage process.

[0026] Please refer to Figures 1 to 4 , the calculation formula for the unit evaluating the overall stability of the abdominal drainage control system is as follows: W = (YX × (LS - LS old ) / LS) - SQRT((YX old - YX) 2 / △T); Where: W is the system stability index, and its value range is from negative to positive. The closer it is to 0, the more stable it is; LS old is the drainage rate before adjustment; YX old is the drainage efficiency before adjustment; △T is the adjustment time difference, and △T reflects the time difference between the drainage after the patient's last adjustment and the start of the current drainage; The calculation formula for the adjustment time difference △T is as follows: △T = T new - T old ; T new is the start time of the current drainage; T old is the end time of the previous drainage.

[0027] In this embodiment, the algorithm unit first calculates the result of the product of the drainage efficiency YX and the change amount of the drainage rate before and after adjustment (LS - LS old ) divided by the drainage rate LS ratio in the part of "(YX × (LS - LS old ) / LS)". This result reflects the degree of influence of the change in the drainage efficiency YX on the system stability in the system stability index W. As a key component in the calculation of the overall stability unit of the abdominal drainage control system, it is used to evaluate the influence of the change in the drainage efficiency YX on the system stability. When this value is large, it indicates that the change in the drainage efficiency YX has a greater impact on the system stability; "SQRT((YX old - YX) 2 / △T)" calculates the square root of the ratio of the square of the change amount of the drainage efficiency before and after adjustment (YX old - YX) to the adjustment time difference △T. This calculation part reflects the degree of influence of the change rate of the drainage efficiency YX on the system stability in the system stability index W. As another key component in the calculation of the overall stability unit of the abdominal drainage control system, it is used to evaluate the influence of the change rate of the drainage efficiency on the system stability. When this value is large, it indicates that the change rate of the drainage efficiency YX is relatively fast, and thus has a greater impact on the system stability; The system stability index W calculated by the overall stability unit of the abdominal drainage control system evaluated by this algorithm can reflect the stable state of the system. When the system stability index W is far from 0, it means that there are unstable factors in the system, including pipeline blockage and abnormal fluctuations in the drainage rate. At this time, the overall stability unit of the abdominal drainage control system can send out a warning signal to prompt timely measures for intervention; According to the positive or negative and magnitude of the system stability index W, the change trend of the system stability can be further judged. Specifically, if the system stability index W is positive and gradually increasing, it means that the system is becoming unstable. If the system stability index W is negative and gradually decreasing, it means that the system is tending to be stable. Thus, the input volume of abdominal fluid YV in and the time interval T parameters can be adjusted to improve the system stability; The system stability index W of the calculation result of the overall stability unit of the abdominal drainage control system can cyclically affect the drainage rate LS in the unit for timely understanding of the current drainage situation of the patient. This means that when the system stability changes, the drainage rate LS will also be adjusted accordingly to adapt to the new stable state. This cyclic influence mechanism helps the system to adaptively adjust parameters to cope with various complex situations, thus ensuring the stability and safety of the drainage process.

[0028] Please refer to Figures 1 to 4 , and the control adjustment based on the system stability index W is as follows: If the result value of the system stability index W is far from 0, and the drained lost liquid volume YV lose has increased compared to the previous drainage, it reflects that there are problems with the control system, including pipeline blockage and poor drainage. When reducing the input abdominal cavity liquid volume YV during the next drainage in ; If the result value of the system stability index W is far from 0, and the drained lost liquid volume YV lose has decreased compared to the previous drainage, it reflects that the drainage efficiency YX of the control system has improved, but the stability is poor. It is judged according to the positive and negative values of the result value of the system stability index W, as follows: If the result value of the system stability index W is positive, it reflects that the control system is too sensitive and responds too quickly. When increasing the time interval T to slow down the change speed of the control system; If the result value of the system stability index W is negative, it reflects that there are problems of insufficient response and being too slow in the control system. When reducing the time interval T to speed up the response speed of the control system; If the result value of the system stability index W is equal to 0, it is considered that the drainage of the control system is normal and stable.

[0029] In this embodiment, based on the evaluation of the overall stability unit of the abdominal drainage control system by this algorithm unit, when the system stability index W is large, the input abdominal cavity liquid volume YV can be adjusted inand the time interval T parameter. Adjusting these parameters directly affects the drainage rate LS in the unit for promptly understanding the patient's current drainage situation, thereby achieving the purpose of dynamically adjusting the drainage rate. Evaluating the cyclic influence of the overall abdominal drainage control system stability unit on the unit for promptly understanding the patient's current drainage situation helps the system adaptively adjust the parameters to optimize the drainage process. Through continuous cyclic feedback and adjustment, the control system can gradually approach the optimal drainage state, thereby improving the drainage efficiency and patient comfort. Moreover, the mechanism of evaluating the cyclic influence of the overall abdominal drainage control system stability unit on the unit for promptly understanding the patient's current drainage situation helps the system improve its stability. When the system stability is poor, by adjusting the parameters and observing the change trend of the system stability index W, the system can be gradually adjusted to a stable state to ensure the safety and effectiveness of the drainage process; This algorithm calculates the drainage rate LS through the unit for promptly understanding the patient's current drainage situation, enabling the control system to real-time according to the input abdominal fluid volume YV in and the drained fluid volume YV out as well as the time interval T to evaluate the current drainage efficiency YX. When the control system detects any abnormalities, including the growth of the drained fluid volume YV lose the control system can respond promptly by adjusting the input abdominal fluid volume YV in and checking and optimizing the drainage system. This real-time and dynamic adaptability helps ensure that the system always operates in the best state; The unit for evaluating the effectiveness of the drainage strategy provides an important indicator for evaluating the system's performance by calculating the drainage efficiency YX. When the drainage efficiency YX is low, the system can attempt to improve stability by adjusting the parameters. This adjustment not only helps reduce the instability of the system but also improves the drainage efficiency, thereby ensuring that more fluid can be drained as expected; The unit for evaluating the overall stability of the abdominal drainage control system provides a comprehensive stability assessment for the control system by calculating the system stability index W. The system stability index W not only reflects the current state of the system but also can be used as a basis for future parameter adjustment, and through the input abdominal fluid volume YV in and T, enabling the control system to optimize its resource utilization, reduce unnecessary waste, and ensure the efficiency and stability of the drainage process; By continuously monitoring and analyzing the change trends of the system stability index W, drainage efficiency YX, and drainage rate LS parameters, the control system can detect potential faults or problems in advance. Specifically, when the drained fluid volume YV loseWhen there is continuous growth and the system stability index W is far from 0, the control system will indicate the occurrence of problems such as pipeline blockage and poor drainage. At this time, by taking preventive measures in a timely manner, the system can avoid failures, thereby extending its service life and reducing maintenance costs; Combining the above feedback loop with advanced control algorithms and technologies can achieve the intelligence and automation of the system. By real-time monitoring and analyzing data, the system can automatically adjust parameters to optimize performance and issue alarms or take other measures to ensure safety when necessary. These characteristics of intelligence and automation not only improve the reliability and stability of the system but also reduce the need and cost of manual intervention; In summary, by combining the unit for timely understanding of the current drainage situation of the patient, the unit for evaluating the effectiveness of the drainage strategy, the unit for evaluating the overall stability of the abdominal drainage control system, and the corresponding adjustment strategies, the system can form an effective feedback loop mechanism. This mechanism not only helps to real-time evaluate and optimize the system performance but also improves stability, efficiency, resource utilization rate, and intelligence level, which is particularly important for medical devices of the abdominal drainage control system because they need to ensure efficient and stable operation in complex and changing environments.

[0030] Embodiment 2, please refer to Figures 1 to 4 , the volume of drained liquid YV out does not include the volume of drained liquid loss YV lose , the volume of drained liquid loss YV lose represents the volume of liquid lost during the drainage process due to reasons including pipeline leakage and system errors. This part of the liquid is not drained as expected but is an additional loss due to system imperfections and external factors. The volume of drained liquid YV out represents the actual volume of liquid drained from the abdominal cavity, which is the result of the normal operation of the control system and reflects the drainage capacity of the control system without losses.

[0031] In this embodiment, according to the definition, the volume of drained liquid YV out is the actual volume of liquid drained from the abdominal cavity, which only includes those liquids that have been successfully drained, while the volume of drained liquid loss YV lose is the loss caused by various reasons and has not been successfully drained, so it should not be included in the volume of drained liquid YV out . If the volume of drained liquid loss YV lose is included in the volume of drained liquid YV out , then it will lead to misjudgment of the drainage effect because the volume of drained liquid loss YV loseIt is not the result of the normal operation of the system, but due to the imperfection of the system and external factors, and it is included in the drained liquid volume YV out will exaggerate the drainage capacity of the system, thus covering up the problems existing in the system; In addition, although the drained loss liquid volume YV lose should not be included in the drained liquid volume YV out However, when analyzing and adjusting the system, these two parameters still need to be considered simultaneously, because the drained loss liquid volume YV lose reflects the loss situation during the drainage process of the system and is one of the important indicators for evaluating the performance stability of the system. By comparing the drained liquid volume YV out and the drained loss liquid volume YV lose in terms of size and proportion, it is then possible to understand the drainage efficiency and loss situation of the system. If the drained loss liquid volume YV lose is large, it indicates that there are significant losses in the system and measures need to be taken for improvement. If the drained liquid volume YV out is large and the drained loss liquid volume YV lose is small, it indicates that the drainage effect of the system is good and the losses are small; In summary, the liquid volume drained from the abdominal cavity, the drained liquid volume YV out does not include the loss liquid volume, the drained loss liquid volume YV lose because the drained loss liquid volume YV lose is an additional loss caused by the imperfection of the system and external factors and has not been successfully drained. When analyzing and adjusting the system, the drained loss liquid volume YV lose and the drained liquid volume YV out need to be considered simultaneously to comprehensively understand the performance and stability of the system.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it is understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
