Description

Technical Field

[0001] This invention relates to the field of adaptive adjustment, specifically to a pressure adaptive adjustment and control system for silicone urinary catheters. Background Technology

[0002] Silicone catheters are used to help users who are unable to urinate independently to drain urine. To improve user comfort, reduce the damage to the urethra that usually occurs during catheterization, and ensure effective urine drainage, silicone catheters need to be pressure-adaptive.

[0003] Existing technology, such as the invention patent with publication number CN103908706B, is an automatic urinary catheterization system. This system can automatically control the closure of the catheter based on changes in urine pressure, achieving automatic urination with high control precision. It can provide individualized control based on different patients and their current posture, maximizing the preservation of normal bladder function. To achieve high-precision, automated control of the automatic urination process, the system's control unit includes an initial value processing unit, a signal processing unit, a urination threshold setting unit, a urination pathway control unit, and an early warning unit. Simultaneously, an intelligent urine volume measurement unit is connected to the end of the catheter containing the electronic drainage valve. The initial value processing unit sets the initial value of the pressure sensor unit, and the signal processing unit processes the collected values ​​from the pressure sensor unit and compares them with the urination threshold set in the urination threshold setting unit. When the urination threshold is reached, the urination pathway control unit opens the urination channel.

[0004] Existing technology, such as CN103055361B, discloses a urinary catheterization device and an abdominal pressure monitoring system. It includes a urinary catheter and a drainage bag for collecting fluid from the catheter. A capillary tube for connecting to a pressure sensor is connected to the catheter. A first control valve is provided on the catheter and between the capillary tube and the drainage bag. A buffer balloon is provided on the capillary tube near the connection point between the capillary tube and the catheter. The urinary catheterization device provided by this invention, through the buffer balloon on the capillary tube, effectively prevents urine from being drawn back into the capillary tube, thereby effectively preventing urine from flowing back to the pressure sensor and causing it to malfunction. This ensures the accuracy of the bladder pressure detected by the pressure sensor and also prevents the pressure sensor from being contaminated by urine, avoiding cross-infection from reusing the sensor.

[0005] As can be seen from the above solutions, existing technologies often focus only on the automated control of equipment and process data in a single way. However, in practical applications, equipment is affected by the usage environment, and the effect varies from person to person, requiring targeted real-time adjustments. At the same time, existing technologies only process pressure data, but the data transmission of the equipment itself also affects the effect. If the data transmission of the equipment itself is abnormal, it may lead to the failure of automated control or cause hardware damage. Therefore, it is necessary to monitor the data transmission nodes of the equipment. Summary of the Invention

The specific processing method is as follows:

[0020] C = (A + 1) 2 *ω1-B 2 *ω2;

[0021] Where 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 weighting factor of the real-time pressure performance value, and ω2 is the weighting factor of the environmental impact value.

[0022] As a preferred technical solution, obtaining the pressure prediction parameters of the silicone catheter to be adjusted specifically includes:

[0023] Historical real-time comprehensive performance values ​​of the adjustable silicone catheter are extracted from the database. Based on these values, the historical real-time comprehensive performance values ​​are analyzed together to obtain pressure prediction parameters for the adjustable silicone catheter. The historical real-time comprehensive performance values ​​characterize the historical performance of the adjustable silicone catheter, while the pressure prediction parameters characterize the real-time pressure change trend within the adjustable silicone catheter.

[0024] As a preferred technical solution, the step of analyzing and processing the pressure prediction parameters and real-time comprehensive performance values ​​of the adjustable silicone catheter to obtain the pressure range adjustment value of the adjustable silicone catheter specifically includes:

[0025] The lower and upper limits of the pressure range of the adjustable silicone catheter are the reflux prevention pressure and the over-prevention pressure, respectively, and the reflux prevention pressure and the over-prevention pressure are the minimum and maximum allowable pressure values ​​of the adjustable silicone catheter, respectively.

[0026] Based on the pressure prediction parameters and real-time comprehensive performance values ​​of the adjustable silicone catheter, the pressure range pre-adjustment index values ​​of the adjustable silicone catheter are obtained through analysis and processing.

[0027] Based on the pre-adjustment index value of the pressure range of the silicone catheter to be adjusted, it is matched with the pressure range adjustment value corresponding to each pressure range pre-adjustment index value range stored in the database to obtain the pressure range adjustment value of the silicone catheter to be adjusted.

[0028] As a preferred technical solution, the adaptive pressure adjustment range is constructed based on the pressure range adjustment value of the silicone catheter to be adjusted, and the pressure range is adjusted and controlled. The specific processing conditions are as follows:

[0029] If the pressure range adjustment value of the silicone catheter to be adjusted is positive, then the pressure range increment corresponding to each pressure range adjustment value stored in the database is matched based on the pressure range adjustment value of the silicone catheter to be adjusted to obtain the pressure range increment of the silicone catheter to be adjusted.

[0030] If the pressure range adjustment value of the silicone catheter to be adjusted is negative, then the pressure range adjustment value of the silicone catheter to be adjusted is matched with the pressure range subtraction value corresponding to each pressure range adjustment value stored in the database to obtain the pressure range subtraction value of the silicone catheter to be adjusted.

[0031] The pressure range of the silicone catheter is controlled and adjusted based on the increase or decrease of the pressure range of the silicone catheter to be adjusted.

[0037] If the network transmission performance value of a certain module is greater than or equal to the network transmission performance threshold of that module, then the network transmission result of that module is determined to be normal.

[0038] If the network transmission performance value of a certain module is less than the network transmission performance threshold of that module, the network transmission result of that module is determined to be abnormal, and the result is sent to the management terminal for warning.

[0039] Compared with the prior art, the embodiments of the present invention have at least the following beneficial effects:

[0043] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0044] Figure 1 This is a schematic diagram of the system modules of the present invention. Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

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

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

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

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

[0051] The real-time pressure data of the adjustable silicone catheter is obtained through a pressure sensor.

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

[0053] Initial pressure is the instantaneous pressure at which the catheter is inserted into the urethra to begin draining urine. It is used to assess the ease of catheter insertion and as a reference for adjusting the catheter's position and angle.

[0054] Peak pressure refers to the highest pressure reached within the catheter during a preset real-time sensing period. It reflects the maximum force exerted by the catheter; excessively high pressure usually causes damage. Average pressure refers to the average pressure within the catheter during the preset real-time sensing period. Pressure fluctuation frequency refers to the frequency of pressure changes within the catheter during the preset real-time sensing period. By monitoring pressure parameters in real time, abnormal pressure conditions can be detected promptly, such as excessively high, low, or large pressure fluctuations, allowing for timely intervention to prevent equipment damage or accidents. Analyzing the trends in pressure parameter changes allows for optimization of equipment operating parameters. It also helps identify equipment fault types, such as leaks or blockages, and enables fault diagnosis. For example, a sudden drop in pressure usually indicates a leak, while abnormal pressure fluctuation frequency usually indicates a blockage.

[0055] Extract a set of usage pressure data comparison values ​​for silicone urinary catheters from the database. The set of usage pressure data comparison values ​​includes initial pressure comparison value, peak pressure comparison value, average pressure comparison value, and pressure fluctuation frequency comparison value.

[0056] Based on the real-time usage pressure data and the set of usage pressure data comparison values ​​of the adjustable silicone urinary catheter during use, the real-time pressure performance value of the adjustable urinary catheter is obtained through processing and analysis. The real-time pressure performance value of the adjustable urinary catheter is used to characterize the internal pressure value performance of the adjustable urinary catheter during use.

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

[0058]

[0059] Where A represents the real-time pressure performance value of the silicone catheter to be adjusted, D represents the real-time initial pressure of the silicone catheter to be adjusted, E represents the real-time peak pressure of the silicone catheter to be adjusted, F represents the real-time average pressure of the silicone catheter to be adjusted, G represents the real-time pressure fluctuation frequency of the silicone catheter to be adjusted, D0 represents the initial pressure reference value, E0 represents the peak pressure reference value, F0 represents the average pressure reference value, and G0 represents the pressure fluctuation frequency reference value. As the initial pressure weighting factor, As the peak pressure weighting factor, As the average pressure weighting factor, is the pressure fluctuation frequency weighting factor, and e is the natural constant.

[0060] It should be noted that the initial pressure weighting factor, peak pressure weighting factor, average pressure weighting factor, and pressure fluctuation frequency weighting factor all have values ​​between 0 and 1, and satisfy the following conditions: The initial pressure weighting factor is a preset influence factor in the database corresponding to the real-time pressure performance value of the silicone catheter to be adjusted. It represents 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 weighting factor is a preset influence factor in the database corresponding to the real-time pressure performance value of the silicone catheter to be adjusted. It represents 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 weighting factor is a preset influence factor in the database corresponding to the real-time pressure performance value of the silicone catheter to be adjusted. It represents 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 weighting factor is a preset influence factor in the database corresponding to the real-time pressure performance value of the silicone catheter to be adjusted. It represents the pressure fluctuation frequency. To determine the impact of the real-time pressure performance of the silicone catheter to be adjusted, the initial pressure weighting factor, peak pressure weighting factor, average pressure weighting factor, and pressure fluctuation frequency weighting factor can be directly obtained from the database. The correspondence between these factors is a pre-defined mapping relationship. For example, the real-time pressure performance of the silicone catheter to be adjusted forms a mapping set with the initial pressure, peak pressure, average pressure, and pressure fluctuation frequency weighting factors corresponding to the initial pressure, peak pressure, average pressure, and pressure fluctuation frequency, respectively. Inputting the real-time initial pressure, real-time peak pressure, real-time average pressure, and real-time pressure fluctuation frequency into this mapping set yields the initial pressure weighting factor, peak pressure weighting factor, average pressure weighting factor, and pressure fluctuation frequency weighting factor, with a one-to-one mapping relationship.

[0061] It should also be noted that there is a certain correlation between the parameters of initial pressure, peak pressure, average pressure, and pressure fluctuation frequency. Peak pressure is usually higher than initial and average pressure, reflecting pressure fluctuation. The difference between peak pressure and initial and average pressure reflects the amplitude of pressure fluctuation; the larger the amplitude, the more drastic the pressure changes the equipment experiences. Average pressure usually falls between initial and peak pressure, reflecting the overall pressure level. The difference between average pressure and initial and peak pressure reflects the range of pressure fluctuation; the larger the range, the wider the pressure variation the equipment experiences. Pressure fluctuation frequency reflects the rate of pressure change. The higher the pressure fluctuation frequency, the faster the pressure changes, and the more drastic the pressure changes the equipment experiences. The difference between pressure fluctuation frequency and initial, peak, and average pressure reflects the amplitude and range of pressure changes. By comprehensively analyzing initial pressure, peak pressure, average pressure, and pressure fluctuation frequency, a more comprehensive understanding of pressure change trends and equipment operating status can be obtained. For example, if the initial and average pressures are low, but the peak pressure is high, it indicates a liquid leak or malfunction in the equipment. If the pressure fluctuation frequency is high, it indicates that the equipment usually has vibration or noise problems.

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

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

[0064] The accuracy interference data of the adjustable silicone catheter includes the cumulative usage time of the adjustable silicone catheter, the mechanical stress caused by the real-time average pressure on the sensor, and the intensity of electromagnetic interference from the external environment.

[0065] Cumulative usage time refers to the total time from the start of use of the silicone urinary catheter to the current moment. The cumulative usage time of the silicone urinary catheter to be adjusted can be obtained from the work log. Assess the wear and aging of the catheter; prolonged use usually leads to a decline in material performance, affecting the accuracy of pressure measurements.

[0066] Mechanical stress refers to the physical force exerted on the built-in pressure sensor by the real-time average pressure within the urinary catheter. It is used to assess the sensor's ability to withstand pressure over long periods; excessive mechanical stress often leads to sensor fatigue or damage. Ensuring the sensor operates within its designed pressure range guarantees the accuracy of the measurement data.

[0067] Electromagnetic interference (EMI) intensity refers to the degree of influence of electromagnetic waves in the external environment on the pressure sensor and control system of the urinary catheter. The EMI intensity of the external environment is collected using an external spectrum analyzer attached to the adjustable silicone urinary catheter. EMI can affect the transmission and reception of sensor signals, leading to data distortion or errors.

[0068] Understanding the common sources of error during measurement helps improve the accuracy of catheter pressure measurements. These parameters can serve as a basis for data correction, allowing for adjustments to reduce errors.

[0069] Extract a set of precision interference data parameters from the database. The precision interference data parameters specifically include cumulative usage time parameters, mechanical stress parameters, and environmental electromagnetic interference intensity parameters.

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

[0071]

[0072] Wherein, 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 usage time of the silicone catheter to be adjusted, I is the mechanical stress of the silicone catheter to be adjusted, J is the external environmental electromagnetic interference intensity of the silicone catheter to be adjusted, H0 is the cumulative usage time parameter value, I0 is the mechanical stress parameter value, J0 is the environmental electromagnetic interference intensity parameter value, β1 is the cumulative usage time weighting factor, β2 is the mechanical stress weighting factor, β3 is the external environmental electromagnetic interference intensity weighting factor, and e is a natural constant.

[0073] It should be noted that the cumulative usage time weighting factor, mechanical stress weighting factor, and external environmental electromagnetic interference intensity weighting factor all range from 0 to 1, and satisfy β1+β2+β3=1. The cumulative usage time weighting factor is an influence factor corresponding to the preset environmental impact value of the silicone catheter to be adjusted in the database, representing the numerical value of the influence of cumulative usage time on the environmental impact value of the silicone catheter to be adjusted. The mechanical stress weighting factor is an influence factor corresponding to the preset environmental impact value of the silicone catheter to be adjusted in the database, representing 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 environmental electromagnetic interference intensity weighting factor is an influence factor corresponding to the preset environmental impact value of the silicone catheter to be adjusted in the database, representing the numerical value of the influence of real-time mechanical stress on the environmental impact value of the silicone catheter to be adjusted. The numerical value representing the degree of influence of interference intensity on the environmental impact value of the silicone catheter to be adjusted can be obtained directly from the database using the cumulative usage time weight factor, mechanical stress weight factor, and external environmental electromagnetic interference intensity weight factor. The correspondence between these factors is a pre-defined mapping relationship. For example, the environmental impact value of the silicone catheter to be adjusted is mapped to the cumulative usage time weight factor, mechanical stress weight factor, and external environmental electromagnetic interference intensity weight factor corresponding to the cumulative usage time, mechanical stress, and external environmental electromagnetic interference intensity, respectively. The real-time cumulative usage time, real-time mechanical stress, and real-time external environmental electromagnetic interference intensity are input into the mapping set to obtain the cumulative usage time weight factor, mechanical stress weight factor, and external environmental electromagnetic interference intensity weight factor. The mapping relationship is one-to-one.

[0074] It should also be noted that there is a certain correlation between the parameters of the cumulative usage time of the silicone catheter to be adjusted, the mechanical stress on the sensor caused by the real-time average pressure, and the intensity of electromagnetic interference in the external environment. As the cumulative usage time increases, the silicone catheter typically ages, wears, or deforms, leading to changes in the real-time average pressure. The mechanical stress on the sensor usually increases with the cumulative usage time, resulting in decreased sensor performance and affecting measurement accuracy. The intensity of electromagnetic interference in the external environment typically affects the sensor's output signal, leading to errors in the real-time average pressure. The higher the electromagnetic interference intensity, the greater the interference to the sensor, and the larger the error in the real-time average pressure.

[0075] By comprehensively analyzing the cumulative usage time, the mechanical stress caused to the sensor by the real-time average pressure, and the intensity of electromagnetic interference from the external environment, we can gain a more complete understanding of the precision 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 catheter to be adjusted, and obtain the real-time pressure performance value of the catheter. Based on the accuracy interference data of the silicone catheter to be adjusted, the environmental impact value is obtained to correct the real-time pressure performance value of the catheter. The comprehensive processing is used to obtain the real-time comprehensive performance value of the silicone catheter to be adjusted.

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

[0078] C = (A + 1) 2 *ω1-B 2 *ω2;

[0079] Where 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 weighting factor of the real-time pressure performance value, and ω2 is the weighting factor of the environmental impact value.

[0080] It should be noted that the weighting factors for real-time pressure performance and environmental impact are both between 0 and 1, and satisfy ω1 + ω2 = 1. The weighting factor for real-time pressure performance is a preset influence factor in the database corresponding to the real-time comprehensive performance value of the silicone catheter to be adjusted, representing the degree of influence of the real-time pressure performance value on the real-time comprehensive performance value of the silicone catheter to be adjusted. The weighting factor for environmental impact is a preset influence factor in the database corresponding to the real-time comprehensive performance value of the silicone catheter to be adjusted, representing the degree of influence of the real-time environmental impact value on the real-time comprehensive performance value of the silicone catheter to be adjusted. When using it, the weighting factors for real-time pressure performance and environmental impact can be directly obtained from the database. Their correspondence is a pre-set mapping relationship. For example, the real-time comprehensive performance value of the silicone catheter to be adjusted forms a mapping set with the weighting factors for real-time pressure performance and environmental impact respectively. Inputting the real-time pressure performance value and real-time environmental impact value into the mapping set yields the weighting factors for real-time pressure performance and environmental impact. The mapping relationship is one-to-one.

[0081] The environmental impact value is obtained based on the accuracy interference data of the adjustable silicone catheter. The real-time pressure performance value of the adjustable catheter is then 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 adjustable silicone catheter.

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

[0083] The specific parameters for obtaining the pressure prediction of the silicone catheter to be adjusted include:

[0084] Historical real-time comprehensive performance values ​​of the adjustable silicone catheter are extracted from the database. Based on these values, the historical and real-time comprehensive performance values ​​are analyzed together to obtain the pressure prediction parameters for the adjustable silicone catheter.

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

[0086] The specific parameters for obtaining the pressure prediction of the silicone catheter to be adjusted include:

[0087]

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

[0089] By jointly analyzing the historical real-time comprehensive performance values ​​of the adjustable silicone urinary catheter and its real-time comprehensive performance values, it is possible to predict the real-time pressure change trend within the catheter, 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 catheter's use. By analyzing historical data, the effectiveness of the catheter's use can be evaluated, and its use can be optimized.

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

[0091] The process of analyzing and processing the pressure prediction parameters and real-time comprehensive performance values ​​of the adjustable silicone catheter to obtain the pressure range adjustment value of the adjustable silicone catheter specifically includes:

[0092] The lower and upper limits of the pressure range of the adjustable silicone catheter are the reflux prevention pressure and the over-prevention pressure, respectively, and the reflux prevention pressure and the over-prevention pressure are the minimum and maximum allowable pressure values ​​of the adjustable silicone catheter, respectively.

[0093] Reflux prevention pressure refers to the minimum pressure set in a urinary catheterization system to prevent reflux. Over-prevention pressure refers to the maximum pressure set in a urinary catheterization system to prevent excessive pressure.

[0094] Based on the pressure prediction parameters and real-time comprehensive performance values ​​of the adjustable silicone catheter, the pressure range pre-adjustment index values ​​of the adjustable silicone catheter are obtained through analysis and processing.

[0095]

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

[0097] Based on the pre-adjustment index value of the pressure range of the silicone catheter to be adjusted, it is matched with the pressure range adjustment value corresponding to each pressure range pre-adjustment index value range stored in the database to obtain the pressure range adjustment value of the silicone catheter to be adjusted.

[0098] The adaptive pressure adjustment range is constructed based on the pressure range adjustment value of the silicone catheter to be adjusted, and the pressure range is adjusted and controlled. The specific processing conditions are as follows:

[0099] If the pressure range adjustment value of the silicone catheter to be adjusted is positive, then the pressure range increment corresponding to each pressure range adjustment value stored in the database is matched based on the pressure range adjustment value of the silicone catheter to be adjusted to obtain the pressure range increment of the silicone catheter to be adjusted.

[0100] If the pressure range adjustment value of the silicone catheter to be adjusted is negative, then the pressure range adjustment value of the silicone catheter to be adjusted is matched with the pressure range subtraction value corresponding to each pressure range adjustment value stored in the database to obtain the pressure range subtraction value of the silicone catheter to be adjusted.

[0101] Based on the increase or decrease of the pressure range of the silicone catheter to be adjusted, the pressure range of the silicone catheter can be controlled and adjusted by introducing air through a pressure regulating device to control the internal pressure of the silicone catheter.

[0102] The pressure range of the silicone catheter is [P1, P2], where P1 is the reflux prevention pressure of the silicone catheter and P2 is the over-prevention pressure of the silicone catheter. In another embodiment of the invention, the pressure range of the silicone catheter is [P1-δ, P2-δ] when the size is controlled and adjusted, where δ is the reduction value of the pressure range of the silicone catheter to be adjusted.

[0103] In this embodiment, the present invention further includes a fault monitoring module, used to acquire the execution parameters of each module of the silicone catheter to be adjusted, and to monitor whether any abnormalities occur in the data transmission of each module, wherein:

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

[0105] Extract the set of network transmission parameter comparison values ​​for each module from the database, specifically including: response time comparison value, data transmission rate comparison value, and information 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 complete the execution of the instruction from receiving it. 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 at which data is transmitted between the modules of the adjustable silicone catheter or between the adjustable silicone catheter and external devices. The higher the transmission rate, the stronger the module's data processing capability 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] Extract the set of network transmission parameter comparison values ​​for each module from the database, specifically including: response time comparison value, data transmission rate comparison value, and information error rate comparison value.

[0110] Monitoring for abnormal data transmission in each module also includes:

[0111] The network transmission parameters of each module of the silicone catheter to be adjusted are comprehensively analyzed and processed with the reference values ​​of the network transmission parameters of each module 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, it is compared with the network transmission performance threshold of each module pre-stored in the database to obtain the network transmission result of each module.

[0112] Based on the network transmission parameters of each module of the adjustable silicone urinary catheter and the corresponding comparison values ​​of the network transmission parameters of each module, the network transmission performance values ​​of each module of the adjustable silicone urinary catheter are analyzed and generated. The specific analysis process is as follows:

[0113]

[0114] Where, N i For the network transmission performance value of the i-th module of the silicone urinary catheter to be adjusted, O i Q is the response time of the i-th module of the silicone catheter to be adjusted. i To adjust the data transmission rate of the i-th module of the silicone urinary catheter, R i Let represent the bit error rate of the i-th module of the silicone catheter to be adjusted, O be the response time reference value, Q be the data transmission rate reference value, R be the bit error rate reference value of each module, e be the natural constant, and i be the module number of the silicone catheter to be adjusted, i = 1, 2, 3, 4, 5.

[0115] It's important to note that there's a correlation between the response time, data transmission rate, and bit error rate of each module. Generally, a higher data transmission rate means faster data exchange between modules, thus shortening the response time. If data can be transmitted quickly, modules can receive the required data and respond more rapidly. If the data transmission rate is low, even with a powerful module, the response time will increase due to waiting for data transmission. A high bit error rate typically leads to data transmission failures or retransmissions, increasing response time because additional time is needed to correct errors or retransmit data. A high bit error rate usually requires modules to implement more acknowledgments and retransmission mechanisms, further extending the response time. Increasing the data transmission rate generally leads to an increased bit error rate because high-speed transmission often exceeds the reliability limits of the communication link, especially under conditions of poor signal quality or strong interference.

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

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

[0118] The network transmission performance threshold is obtained by extracting it from the database and is used to comprehensively evaluate the network transmission performance of each module of the silicone 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 adjustment and control system for the silicone catheter involved in this embodiment of the invention. There are various methods for setting the network transmission performance threshold, such as obtaining it through statistical analysis, including statistically analyzing the network transmission performance values ​​under historically poor network transmission performance conditions (e.g., the response time of a certain 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 setting the threshold based on the boundary between high and low network transmission performance values ​​determined by corresponding historical data, thereby adjusting the threshold.

[0120] By monitoring the network transmission results of each module, we can understand the data transmission performance of each module, such as latency and bandwidth utilization, and thus perform targeted optimizations. When network transmission problems occur, the transmission results can provide a basis for fault diagnosis, helping to quickly locate the module with the problem. Monitoring network transmission results can help detect potential security threats, enabling timely discovery and response, and protecting the system from damage.
