Description

Technical Field

[0001] The invention relates to the field of adaptive regulation, in particular to a pressure adaptive regulation and control system for a silicone urinary catheter. Background Art

[0002] Silicone urinary catheters are used to help users who cannot urinate on their own to drain urine. In order to improve the user's comfort, reduce the damage to the urethra that is usually caused during catheterization, and ensure the effectiveness of urine drainage, silicone urinary catheters need to be able to adjust pressure adaptively.

[0003] The prior art, such as the invention patent with announcement number: CN103908706B, is an automatic urinary catheterization system that can automatically control the closing of the urinary catheter according to the change of human urine pressure to achieve automatic urination, and has high control accuracy. It can achieve individualized control according to different patients and the patient's current posture, and maximize the normal bladder function of the patient. In order to achieve high-precision and automated control of the automatic urination process, an initial value processing unit, a signal processing unit, a urination threshold setting unit, a urination channel control unit and an early warning unit are set in the control unit of the system; at the same time, an intelligent urine volume measurement unit is connected to the end of the catheter where the electronic drainage valve is located. The initial value processing unit is used to set the initial value of the pressure sensor unit, and the signal processing unit is used to perform signal processing on the collected value of the pressure sensor unit and compare it with the urination threshold set in the urination threshold setting unit. When the urination threshold is reached, the urination channel control unit opens the urination channel.

[0004] The prior art, such as the announcement number: CN103055361B, is a urinary catheterization device and abdominal pressure monitoring system. It includes: a urinary catheter and a drainage bag for collecting liquid in the urinary catheter, the urinary catheter is connected to a capillary for connecting to a pressure sensor; a first control valve is provided on the urinary catheter and between the capillary and the drainage bag; a buffer air bag is provided on the capillary and near the connection between the capillary and the urinary catheter. The urinary catheterization device provided by the present invention can effectively prevent urine in the urinary catheter from being sucked back into the capillary by means of the buffer air bag provided on the capillary, thereby effectively preventing urine from flowing back into the pressure sensor and causing the pressure sensor to malfunction, thereby ensuring the accuracy of the bladder pressure detected by the pressure sensor, and preventing the pressure sensor from being contaminated by urine, thereby avoiding cross infection caused by reuse of the sensor.

[0005] Based on the above scheme, it can be seen that the existing technology often only focuses on the automatic control of the equipment and processes the data in a single way. In actual applications, the equipment will be affected by the use environment, and the use effect will vary from person to person, so targeted real-time adjustment is required. At the same time, the existing technology only processes the pressure data, but the data transmission of the equipment itself will also affect the use effect. If the data transmission of the equipment itself is abnormal, it may cause the automatic control to fail or cause hardware damage. Therefore, it is necessary to monitor the data transmission nodes of the equipment. Summary of the invention

[0044] Figure 1 It is a schematic diagram of the system module of the present invention. DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0047] See also Figure 1 As shown, an embodiment of the present invention provides a pressure adaptive regulation and control system for a silicone urinary catheter, comprising:

[0048] The pressure sensing module is used to obtain real-time usage pressure data of the silicone urinary catheter to be adjusted during use.

[0049] The step of obtaining the real-time pressure data of the silicone urinary catheter to be adjusted during use specifically includes:

[0050] The real-time usage pressure data includes an initial pressure, a peak pressure, an average pressure, and a pressure fluctuation frequency in a preset real-time sensing period.

[0051] The real-time usage pressure data of the silicone urinary catheter to be adjusted is obtained through a pressure sensor.

[0052] In another embodiment of the invention, the preset real-time sensing period length is 1 minute.

[0053] Initial pressure refers to the instantaneous pressure when the catheter is inserted into the urethra and begins to drain urine. It is used to assess the ease of catheter insertion and as a reference for adjusting the position and angle of the catheter.

[0054] Peak pressure refers to the highest value reached by the pressure in the catheter during the preset real-time sensing period. It reflects the maximum force acting on the catheter, and too high pressure usually causes damage. Average pressure refers to the average value of the pressure in the catheter during the preset real-time sensing period. Pressure fluctuation frequency refers to the frequency of pressure changes in the catheter during the preset real-time sensing period. By real-time monitoring of pressure parameters, abnormal pressure conditions can be discovered in time, such as excessive pressure, too low pressure, excessive fluctuations, etc., so that timely measures can be taken to avoid equipment damage or accidents. By analyzing the changing trend of pressure parameters, the operating parameters of the equipment can be optimized. By analyzing the changing trend of pressure parameters, the fault type of the equipment, such as leakage, blockage, etc., can be identified and fault diagnosis can be performed. For example, when the pressure drops suddenly, it can be judged that the equipment usually has a leak. When the pressure fluctuation frequency is abnormal, it can be judged that the equipment usually has a blockage.

[0055] A set of pressure data control values ​​for the silicone urinary catheter is extracted from the database, wherein the set of pressure data control values ​​includes an initial pressure control value, a peak pressure control value, an average pressure control value, and a pressure fluctuation frequency control value.

[0056] Based on the real-time usage pressure data of the silicone urinary catheter to be adjusted during use and a set of usage pressure data control values, the real-time pressure performance value of the urinary catheter to be adjusted is processed and analyzed to obtain the real-time pressure performance value of the urinary catheter to be adjusted, and the real-time pressure performance value of the urinary catheter to be adjusted is used to characterize the internal pressure value performance of the catheter to be adjusted during use.

[0057] The real-time pressure data of the silicone urinary catheter to be adjusted during use and the control value set of the pressure data of the silicone urinary catheter are compared and analyzed to obtain the real-time pressure performance value of the silicone urinary catheter to be adjusted. The specific processing method is as follows:

[0058]

[0059] Wherein, A is the real-time pressure performance value of the silicone urinary catheter to be adjusted, D is the real-time initial pressure of the silicone urinary catheter to be adjusted, E is the real-time peak pressure of the silicone urinary catheter to be adjusted, F is the real-time average pressure of the silicone urinary catheter to be adjusted, G is the real-time pressure fluctuation frequency of the silicone urinary catheter to be adjusted, D0 is the initial pressure control value, E0 is the peak pressure control value, F0 is the average pressure control value, G0 is the pressure fluctuation frequency control value, is the initial pressure weight factor, is the peak pressure weight factor, is the average pressure weight factor, is the pressure fluctuation frequency weight factor, and e is a natural constant.

[0060] It should be noted that the initial pressure weight factor, peak pressure weight factor, average pressure weight factor and pressure fluctuation frequency weight factor all have a value range between 0 and 1 and satisfy The initial pressure weight factor is an influence factor corresponding to the real-time pressure performance value of the silicone catheter to be adjusted preset in the database, which indicates the numerical value of the influence of the real-time initial pressure on the real-time pressure performance value of the silicone catheter to be adjusted. The peak pressure weight factor is an influence factor corresponding to the real-time pressure performance value of the silicone catheter to be adjusted preset in the database, which indicates the numerical value of the influence of the real-time peak pressure on the real-time pressure performance value of the silicone catheter to be adjusted. The average pressure weight factor is an influence factor corresponding to the real-time pressure performance value of the silicone catheter to be adjusted preset in the database, which indicates the numerical value of the influence of the average pressure on the real-time pressure performance value of the silicone catheter to be adjusted. The pressure fluctuation frequency weight factor is an influence factor corresponding to the real-time pressure performance value of the silicone catheter to be adjusted preset in the database, which indicates the pressure fluctuation frequency. The numerical value of the degree of influence on the real-time pressure performance value of the silicone urinary catheter to be adjusted can be used to directly obtain the initial pressure weight factor, peak pressure weight factor, average pressure weight factor and pressure fluctuation frequency weight factor from the database, and the corresponding relationship is a pre-set mapping relationship. For example: the real-time pressure performance value of the silicone urinary catheter to be adjusted and the initial pressure, peak pressure, average pressure and pressure fluctuation frequency corresponding to the initial pressure, peak pressure, average pressure and pressure fluctuation frequency respectively form a mapping set, and the real-time initial pressure, real-time peak pressure, real-time average pressure and real-time pressure fluctuation frequency are input into the mapping set to obtain the initial pressure weight factor, peak pressure weight factor, average pressure weight factor and pressure fluctuation frequency weight factor, and the mapping relationship is one-to-one correspondence.

[0061] It should also be noted that there is a certain correlation between the initial pressure, peak pressure, average pressure and pressure fluctuation frequency. The peak pressure is usually higher than the initial pressure and average pressure, reflecting the pressure fluctuation. The difference between the peak pressure and the initial pressure and average pressure can reflect the pressure fluctuation amplitude. The larger the fluctuation amplitude, the more drastic the pressure change the equipment is subjected to. The average pressure is usually between the initial pressure and the peak pressure, reflecting the overall level of pressure. The difference between the average pressure and the initial pressure and peak pressure can reflect the pressure fluctuation range. The larger the fluctuation range, the wider the pressure change range the equipment is subjected to. The pressure fluctuation frequency reflects the speed of pressure change. The higher the pressure fluctuation frequency, the faster the pressure change and the more drastic the pressure change the equipment is subjected to. The difference between the pressure fluctuation frequency and the initial pressure, peak pressure and average pressure can reflect the amplitude and range of pressure change. By comprehensively analyzing the initial pressure, peak pressure, average pressure and pressure fluctuation frequency, we can have a more comprehensive understanding of the pressure change trend and the operating status of the equipment. For example, if the initial pressure and average pressure are low, but the peak pressure is high, it means that there is a liquid leak or failure in the equipment. If the pressure fluctuates at a high frequency, this usually indicates a vibration or noise problem with the equipment.

[0062] The data statistics module is used to collect the precision interference data of the silicone urinary catheter to be adjusted and send it to the data processing module.

[0063] The method of collecting the precision interference data of the silicone urinary catheter to be adjusted and sending the data to the data processing module specifically includes:

[0064] The precision interference data of the silicone urinary catheter to be adjusted include the accumulated use time of the silicone urinary catheter to be adjusted, the mechanical stress caused by the real-time average pressure on the sensor, and the electromagnetic interference intensity of the external environment.

[0065] The cumulative usage time refers to the total length of time from the start of use of the silicone catheter to the current moment. The cumulative usage time of the silicone catheter to be adjusted can be obtained through the records in the work log. Evaluate the degree of wear and aging of the catheter. Long-term use usually leads to a decrease in material performance, affecting the accuracy of pressure measurement.

[0066] Mechanical stress refers to the physical force exerted by the real-time average pressure in the catheter on the built-in pressure sensor. It is used to evaluate the sensor's ability to withstand pressure for a long time. Excessive mechanical stress usually causes sensor fatigue or damage. Ensure that the sensor works within the designed pressure range to ensure the accuracy of the measurement data.

[0067] Electromagnetic interference intensity refers to the degree of influence of electromagnetic waves in the external environment on the catheter pressure sensor and its control system. The electromagnetic interference intensity of the external environment is collected by an external spectrum analyzer on the silicone catheter to be adjusted. Electromagnetic interference can affect the transmission and reception of sensor signals, resulting in data distortion or errors.

[0068] Understanding the common sources of error during measurement can help improve the accuracy of catheter pressure measurements. These parameters can be used as a basis for data correction and can be adjusted to reduce errors.

[0069] A precision interference data parameter set is extracted from a database, wherein the precision interference data parameter values ​​specifically include a cumulative usage time parameter value, a mechanical stress parameter value, and an environmental electromagnetic interference intensity parameter value.

[0070] Based on the precision interference data and precision interference data parameter set of the silicone urinary catheter to be adjusted, the environmental impact value of the silicone urinary catheter to be adjusted is obtained through analysis and processing. The specific processing method is as follows:

[0071]

[0072] Among them, B is the environmental impact value of the silicone catheter to be adjusted, C is the real-time comprehensive performance value of the silicone catheter to be adjusted, H is the cumulative use time of the silicone catheter to be adjusted, I is the mechanical stress of the silicone catheter to be adjusted, J is the external environment electromagnetic interference intensity of the silicone catheter to be adjusted, H0 is the cumulative use time parameter value, I0 is the mechanical stress parameter value, J0 is the environmental electromagnetic interference intensity parameter value, β1 is the cumulative use time weight factor, β2 is the mechanical stress weight factor, β3 is the external environment electromagnetic interference intensity weight factor, and e is a natural constant.

[0073] It should be noted that the cumulative usage time weight factor, the mechanical stress weight factor and the external environment electromagnetic interference intensity weight factor all have a value range between 0 and 1, and satisfy β1+β2+β3=1. The cumulative usage time weight factor is the influence factor corresponding to the environmental impact value of the silicone catheter to be adjusted preset in the database, which indicates the numerical value of the influence of the cumulative usage time on the environmental impact value of the silicone catheter to be adjusted. The mechanical stress weight factor is the influence factor corresponding to the environmental impact value of the silicone catheter to be adjusted preset in the database, which indicates the numerical value of the influence of real-time mechanical stress on the environmental impact value of the silicone catheter to be adjusted. The external environment electromagnetic interference intensity weight factor is the influence factor corresponding to the environmental impact value of the silicone catheter to be adjusted preset in the database, which indicates the external environment electromagnetic The numerical value of the influence of the interference intensity on the environmental impact value of the silicone catheter to be adjusted can be used to directly obtain the cumulative usage time weight factor, mechanical stress weight factor and external environment electromagnetic interference intensity weight factor from the database when used, and the corresponding relationship is a pre-set mapping relationship. For example: the environmental impact value of the silicone catheter to be adjusted and the cumulative usage time, mechanical stress and external environment electromagnetic interference intensity corresponding to the cumulative usage time, mechanical stress and the cumulative usage time weight factor, mechanical stress weight factor and external environment electromagnetic interference intensity form a mapping set, and the real-time cumulative usage time, real-time mechanical stress and real-time external environment electromagnetic interference intensity are input into the mapping set to obtain the cumulative usage time weight factor, mechanical stress weight factor and external environment electromagnetic interference intensity weight factor, and the mapping relationship is one-to-one correspondence.

[0074] It should also be noted that there is a certain correlation between the cumulative usage time of the silicone catheter to be adjusted, the mechanical stress caused by the real-time average pressure on the sensor, and the intensity of electromagnetic interference in the external environment. As the cumulative usage time increases, the silicone catheter will usually age, wear or deform, resulting in changes in the real-time average pressure. As the cumulative usage time increases, the mechanical stress on the sensor usually increases, resulting in a decrease in sensor performance and affecting the measurement accuracy. The intensity of electromagnetic interference in the external environment usually affects the output signal of the sensor, resulting in an error in the real-time average pressure. The higher the electromagnetic interference intensity, the greater the interference to the sensor, and the greater the error in the real-time average pressure.

[0075] By comprehensively analyzing the accumulated usage time, the mechanical stress caused by the real-time average pressure on the sensor, and the intensity of electromagnetic interference in the external environment, we can have a more comprehensive understanding of the accuracy interference of the silicone catheter to be adjusted.

[0076] The data processing module is used to process and analyze the real-time usage pressure data of the silicone urinary catheter to be adjusted, and obtain the real-time pressure performance value of the catheter to be adjusted. The environmental impact value is obtained based on the precision interference data of the silicone urinary catheter to be adjusted to correct the real-time pressure performance value of the catheter to be adjusted, and the real-time comprehensive performance value of the silicone urinary catheter to be adjusted is obtained through comprehensive processing.

[0077] The environmental impact value obtained based on the precision interference data of the silicone urinary catheter to be adjusted is used to correct the real-time pressure performance value of the urinary catheter to be adjusted, and the real-time comprehensive performance value of the silicone urinary catheter to be adjusted is obtained by comprehensive processing. The specific processing method is:

[0078] C=(A+1) 2 *ω1-B 2 *ω2;

[0079] Among them, A is the real-time pressure performance value of the silicone catheter to be adjusted, B is the environmental impact value of the silicone catheter to be adjusted, C is the real-time comprehensive performance value of the silicone catheter to be adjusted, ω1 is the real-time pressure performance value weight factor, and ω2 is the environmental impact value weight factor.

[0080] It should be noted that the real-time pressure performance value weight factor and the environmental impact value weight factor both have a value range between 0 and 1, and satisfy ω1+ω2=1. The real-time pressure performance value weight factor is an influence factor corresponding to the real-time comprehensive performance value of the silicone catheter to be adjusted preset in the database, indicating the numerical value of the influence degree of the real-time pressure performance value on the real-time comprehensive performance value of the silicone catheter to be adjusted. The environmental impact value weight factor is an influence factor corresponding to the real-time comprehensive performance value of the silicone catheter to be adjusted preset in the database, indicating the numerical value of the influence degree of the real-time environmental impact value on the real-time comprehensive performance value of the silicone catheter to be adjusted. When used, the real-time pressure performance value weight factor and the environmental impact value weight factor can be directly obtained from the database, and the corresponding relationship is a pre-set mapping relationship. For example: the real-time comprehensive performance value of the silicone catheter to be adjusted and the real-time pressure performance value weight factor and the environmental impact value weight factor corresponding to the real-time pressure performance value and the environmental impact value respectively form a mapping set, and the real-time pressure performance value and the real-time environmental impact value are input into the mapping set to obtain the real-time pressure performance value weight factor and the environmental impact value weight factor, wherein the mapping relationship is one-to-one correspondence.

[0081] The environmental impact value is obtained based on the precision interference data of the silicone urinary catheter to be adjusted, and the real-time pressure performance value of the urinary catheter to be adjusted is corrected. By correcting the environmental impact value, the influence of environmental factors on the measurement results can be further eliminated or reduced, thereby improving the pressure measurement accuracy of the silicone urinary catheter to be adjusted.

[0082] The pressure prediction module analyzes and processes the real-time comprehensive performance value of the silicone urinary catheter to be adjusted together with the historical real-time comprehensive performance value of the silicone urinary catheter to be adjusted, obtains the pressure prediction parameters of the silicone urinary catheter to be adjusted and transmits them to the intelligent control module.

[0083] The step of obtaining the pressure prediction parameters of the silicone urinary catheter to be adjusted specifically includes:

[0084] The historical real-time comprehensive performance values ​​of the silicone urinary catheter to be adjusted are extracted from the database, and based on the real-time comprehensive performance values ​​of the silicone urinary catheter to be adjusted, the historical real-time comprehensive performance values ​​of the silicone urinary catheter to be adjusted and the real-time comprehensive performance values ​​of the silicone urinary catheter to be adjusted are jointly analyzed and processed to obtain the pressure prediction parameters of the silicone urinary catheter to be adjusted.

[0085] The historical real-time comprehensive performance value of the silicone urinary catheter to be adjusted is used to characterize the historical usage performance of the silicone urinary catheter to be adjusted, and the pressure prediction parameter of the silicone urinary catheter to be adjusted is used to characterize the real-time pressure change trend in the urinary catheter to be adjusted.

[0086] The step of obtaining the pressure prediction parameters of the silicone urinary catheter to be adjusted specifically includes:

[0087]

[0088] Wherein, L is the pressure prediction parameter of the silicone urinary catheter to be adjusted, C is the real-time comprehensive performance value of the silicone urinary catheter to be adjusted, C0 is the historical real-time comprehensive performance value of the silicone urinary catheter to be adjusted, and e is a natural constant.

[0089] By jointly analyzing and processing the historical real-time comprehensive performance values ​​of the silicone catheter to be adjusted and the real-time comprehensive performance values ​​of the silicone catheter to be adjusted, the real-time pressure change trend in the catheter can be predicted, thereby providing early warning of problems such as urinary tract obstruction or abnormal pressure. The historical real-time comprehensive performance values ​​can reflect the effectiveness of the use of the catheter. By analyzing historical data, the effectiveness of the use of the catheter can be evaluated and the use of the catheter can be optimized.

[0090] The intelligent control module analyzes and processes the pressure prediction parameters and real-time comprehensive performance values ​​of the silicone urinary catheter to be adjusted to obtain the pressure range adjustment value of the silicone urinary catheter to be adjusted, and constructs an adaptive pressure adjustment range based on the pressure range adjustment value of the silicone urinary catheter to be adjusted to adjust and control the pressure range.

[0091] The pressure prediction parameter and the real-time comprehensive performance value of the silicone urinary catheter to be adjusted are analyzed and processed to obtain the pressure range adjustment value of the silicone urinary catheter to be adjusted, specifically including:

[0092] The lower limit and upper limit of the pressure range of the silicone urinary catheter to be adjusted are the reflux prevention pressure and the over-prevention pressure respectively, and the reflux prevention pressure and the over-prevention pressure are the minimum allowable pressure and the maximum allowable pressure of the silicone urinary catheter to be adjusted respectively.

[0093] Reflux prevention pressure is the lowest pressure set in the catheter system to prevent reflux. Overpressure prevention pressure is the highest pressure set in the catheter system to prevent overpressure.

[0094] Based on the pressure prediction parameters and real-time comprehensive performance values ​​of the silicone urinary catheter to be adjusted, the pressure range pre-adjustment indication value of the silicone urinary catheter to be adjusted is obtained through analysis and processing.

[0096] Among them, M is the pressure range pre-adjustment indicator value of the silicone urinary catheter to be adjusted, L is the pressure prediction parameter of the silicone urinary catheter to be adjusted, and C is the real-time comprehensive performance value of the silicone urinary catheter to be adjusted.

[0097] Based on the pressure interval pre-adjustment indication value of the silicone urinary catheter to be adjusted, the pressure interval adjustment value corresponding to each pressure interval pre-adjustment indication value interval stored in the database is matched to obtain the pressure interval adjustment value of the silicone urinary catheter to be adjusted.

[0098] The pressure interval is adjusted and controlled by constructing an adaptive pressure adjustment interval based on the pressure interval adjustment value of the silicone urinary catheter to be adjusted. The specific processing conditions are:

[0099] If the pressure interval adjustment value of the silicone urinary catheter to be adjusted is positive, the pressure interval adjustment value of the silicone urinary catheter to be adjusted is matched with the pressure interval increments corresponding to the pressure interval adjustment values ​​stored in the database to obtain the pressure interval increment of the silicone urinary catheter to be adjusted.

[0100] If the pressure interval adjustment value of the silicone urinary catheter to be adjusted is negative, the pressure interval adjustment value of the silicone urinary catheter to be adjusted is matched with the pressure interval impairment values ​​corresponding to each pressure interval adjustment value stored in the database to obtain the pressure interval impairment value of the silicone urinary catheter to be adjusted.

[0101] Based on the increase in the pressure range of the silicone urinary catheter to be adjusted or the decrease in the pressure range of the silicone urinary catheter to be adjusted, air is introduced through the pressure regulating device to control the pressure inside the silicone urinary catheter to achieve the size control and adjustment of the pressure range of the silicone urinary catheter.

[0102] The pressure range of the silicone urinary catheter is [P1, P2], where P1 is the reflux prevention pressure of the silicone urinary catheter, and P2 is the excessive prevention pressure of the silicone urinary catheter. In another embodiment of the invention, the pressure range of the silicone urinary catheter during size control and adjustment is [P1-δ, P2-δ], where δ is the pressure range subtraction of the silicone urinary catheter to be adjusted.

[0103] In this embodiment, the present invention also includes a fault monitoring module for obtaining execution parameters of each module of the silicone urinary catheter to be adjusted and monitoring whether data transmission of each module is abnormal, wherein:

[0104] The network transmission parameters of each module of the silicone urinary catheter to be adjusted include: the response time of each module, the data transmission rate of each module and the information bit error rate of each module.

[0105] A set of comparison values ​​of network transmission parameters of each module is extracted from the database, specifically including: a response time comparison value, a data transmission rate comparison value and an information bit error rate comparison value.

[0106] The response time of each module refers to the time required for each module of the silicone catheter to be adjusted to receive a command and execute the command. It reflects the response speed of each module. The shorter the response time, the more sensitive the device carrying the module.

[0107] The data transmission rate of each module refers to the speed of data transmission between modules of the silicone urinary catheter to be adjusted or between the silicone urinary catheter to be adjusted and an external device. The higher the transmission rate, the stronger the module's ability to process data and the higher the data transmission efficiency.

[0108] The bit error rate of each module refers to the probability of errors occurring during data transmission. The lower the bit error rate, the more reliable the data transmission and the more stable the module.

[0109] A set of comparison values ​​of network transmission parameters of each module is extracted from the database, specifically including: a response time comparison value, a data transmission rate comparison value and an information bit error rate comparison value.

[0110] Monitor whether data transmission of each module is abnormal, including:

[0111] The network transmission parameters of each module of the silicone catheter to be adjusted and the network transmission parameter control value set of each module are comprehensively analyzed and processed to obtain the network transmission performance value of each module. Based on the network transmission performance value of each module of the silicone catheter to be adjusted, the network transmission performance threshold of each module pre-stored in the database is compared to obtain the network transmission result of each module.

[0112] Based on the network transmission parameters of each module of the silicone urinary catheter to be adjusted and the set of network transmission parameter comparison values ​​of each module, the network transmission performance values ​​of each module of the silicone urinary catheter to be adjusted are generated by analysis and processing. The specific analysis process is as follows:

[0113]

[0114] Among them, N i is the network transmission performance value of the ith module of the silicone urinary catheter to be adjusted, O i is the response time of the ith module of the silicone urinary catheter to be adjusted, Q i is the data transmission rate of the ith module of the silicone urinary catheter to be adjusted, R i is the information bit error rate of the i-th module of the silicone urinary catheter to be adjusted, O is the response time control value, Q is the data transmission rate control value, R is the information bit error rate control value of each module, e is a natural constant, i is the module number of the silicone urinary catheter to be adjusted, i=1,2,3,4,5.

[0115] It should be noted that there is a certain correlation between the parameters of each module response time, each module data transmission rate and each module information bit error rate. Generally, the higher the data transmission rate, the faster the data exchange between modules, which can shorten the response time. If the data can be transmitted quickly in a short time, the module can receive the required data and respond faster. If the data transmission rate is low, even if the module has strong processing power, the response time will increase due to waiting for data transmission. If the information bit error rate is high, it will usually cause data transmission failure or need to be retransmitted, which will increase the response time. Because it takes extra time to correct errors or retransmit data. High bit error rates usually require more confirmation and retransmission mechanisms for the module, which will further extend the response time. Increased data transmission rates usually lead to increased bit error rates, because high-speed transmission usually exceeds the reliability range of the communication link, especially in the case of poor signal quality or strong interference.

[0116] If the network transmission performance value of a module is greater than or equal to the network transmission performance threshold of the module, the network transmission result of the module is determined to be normal.

[0117] If the network transmission performance value of a module is less than the network transmission performance threshold of the module, the network transmission result of the module is determined to be abnormal, and the result is sent to the management terminal for early warning.

[0118] The network transmission performance threshold is obtained by extraction from a database and is used to comprehensively evaluate the network transmission performance of each module of the silicone urinary catheter to be adjusted.

[0119] The network transmission performance threshold is processed as follows: in a specific embodiment, the network transmission performance threshold is set directly in the database during the development of the pressure adaptive regulation and control system of the silicone urinary catheter involved in the embodiment of the present invention. There are many methods for setting the network transmission performance threshold, such as obtaining it through statistical analysis, including counting the network transmission performance values ​​under historical poor network transmission performance states (for example, the response time of a module is greater than or equal to 10 milliseconds), and averaging the network transmission performance values ​​obtained multiple times to obtain the network transmission performance threshold, or experts judge the boundary between high network transmission performance values ​​and low network transmission performance values ​​through corresponding historical data to set the threshold, thereby adjusting the threshold.

[0120] By monitoring the network transmission results of each module, you can understand the data transmission performance of each module, such as latency, bandwidth utilization, etc., so as to perform targeted optimization. When there is a problem with network transmission, the transmission results can provide a basis for fault diagnosis and help quickly locate the module where the problem occurs. Monitoring network transmission results can help detect potential security threats, discover and respond in a timely manner, and protect the system from damage.
