Description

Technical Field

[0001] The invention relates to the technical field of pressure regulation of silicone urinary catheters, and in particular to a pressure self-adapting regulation system for silicone urinary catheters. Background Art

[0002] In modern medicine, the use of urinary catheters is very common, especially in patients who require long-term indwelling catheterization. However, traditional urinary catheters often face some problems during use, such as obstruction of the catheter, excessive or insufficient pressure, etc. These problems may cause discomfort, infection or other complications to the patient. Therefore, performance improvement and function enhancement of urinary catheters have become an important direction for the development of current medical technology.

[0003] For example, the invention patent with announcement number CN104922777B announces a catheter with adjustable head opening size, including a straight catheter, three sliding guide wires built into the side wall of the straight catheter at medium intervals, the front end of the guide wire is connected to the end of the catheter, and an adjustment switch for adjusting the extension of the guide wire is provided at the rear end of the catheter. When inserting the catheter, the head opening can be slightly reduced, and after indwelling, the opening can be enlarged or closed as needed.

[0004] For example, the invention patent with publication number CN118320279A discloses a urinary catheter, including a urinary catheter body and a flexible pressure sensing unit, wherein the flexible pressure sensing unit is coated on the portion of the urinary catheter body inserted into the bladder. When the urinary catheter body is inserted into the bladder, the flexible pressure sensing unit can detect the pressure in the bladder in real time and transmit the pressure value to an external pressure monitoring device. Medical staff can obtain the pressure value in the bladder through the pressure monitoring device to determine whether the urinary catheter has a blockage problem.

[0005] However, in the process of implementing the technical solution of the invention in the embodiments of the present application, the present application found that the above technology has at least the following technical problems:

[0006] The existing silicone catheter pressure regulation system requires medical staff to manually adjust the catheter, and cannot respond to changes in bladder pressure in real time. As a result, when the bladder pressure changes suddenly, the catheter pressure cannot be adjusted in time, resulting in poor urine discharge. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a pressure adaptive regulation system for a silicone urinary catheter, which can effectively solve the problems involved in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a pressure adaptive regulation system for silicone urinary catheters, including a silicone urinary catheter monitoring module, which is used to detect and obtain the internal information of each silicone urinary catheter in a simulated state, analyze and obtain the function index of each urinary catheter, and compare it with the preset catheter function index boundary value of the pressure regulation database. If the function index of a certain catheter is less than the preset catheter function index boundary value, an early warning prompt is given to the function of the catheter. If the function index of a certain catheter is greater than or equal to the preset catheter function index boundary value, a pressure sensing module is entered; the pressure sensing module is used to count a number of catheters corresponding to the catheter function index greater than or equal to the preset catheter function index boundary value. , and recorded as each well-functioning catheter, real-time monitoring of the pressure data of the area to which each well-functioning catheter belongs, and analysis, to obtain the pressure stability index of each well-functioning catheter; a pressure regulation module, for comparing the pressure stability index of each well-functioning catheter with the preset catheter pressure stability threshold, to obtain each catheter requiring pressure regulation, and automatically regulating the pressure of each catheter requiring pressure regulation; an adjustment warning module, for obtaining the adjustment data of each catheter requiring pressure regulation within the pressure regulation cycle, analyzing, to obtain the pressure regulation stability index of each catheter requiring pressure regulation, and comparing with the catheter pressure regulation stability index threshold preset in the pressure regulation database, and finally giving an early warning prompt for the pressure regulation of each catheter requiring pressure regulation.

[0009] As a further solution, the specific analysis process of each urinary catheter function index is as follows:

[0010] The total urine flow rate of each catheter during the function determination period is divided by the total number of catheterizations to obtain the average urine flow rate of each catheter during the function determination period.

[0011] The balloon water content, average flow rate, average flow rate of catheterized urine and average pressure inside the catheter of each catheter during the function determination period were comprehensively analyzed to obtain the function index of each catheter. The specific analysis method is as follows:

[0012]

[0013] In the formula, F v is the vth catheter function index, v is the number of each catheter, v = 1, 2, 3, ... m, m is the total number of catheters, e is a natural constant, NL v is the average flow rate of catheterized urine during the function determination cycle of the vth catheter, ΔNL is the reference flow rate of catheterized urine preset in the pressure regulation database, and NS v is the average flow rate of urine during the function determination cycle of the vth catheter, ΔNS is the reference flow rate of urine preset in the pressure regulation database, and NW vis the airbag water content of the vth catheter in the function determination cycle, ΔNW is the reference water content of the catheter airbag preset in the pressure regulation database, and NY v is the average pressure inside the vth catheter during the function determination cycle, and ΔNY is the reference pressure inside the catheter preset in the pressure regulation database.

[0014] As a further solution, the specific analysis process of the pressure stability index of each well-functioning urinary catheter is as follows:

[0015] The internal pressure of each well-functioning catheter corresponding to the current simulated use time point is obtained.

[0016] The internal pressure of the catheter, the simulated bladder pressure and the simulated urethra pressure corresponding to each well-functioning catheter at the current simulated use time point are comprehensively analyzed to obtain the pressure stability index of each well-functioning catheter.

[0017] As a further solution, the pressure stability index of each well-functioning urinary catheter is compared with a preset urinary catheter pressure stability threshold to obtain each urinary catheter that needs pressure regulation. The specific comparison process is:

[0018] If the pressure stability index of a well-functioning catheter is not equal to the preset catheter pressure stability threshold, the catheter is recorded as a catheter requiring pressure regulation.

[0019] Among them, if the pressure stability index of a well-functioning catheter is less than the preset catheter pressure stability threshold, the catheter requiring pressure regulation is recorded as the first pressure-regulated catheter; if the pressure stability index of a well-functioning catheter is greater than the preset catheter pressure stability threshold, the catheter requiring pressure regulation is recorded as the second pressure-regulated catheter.

[0020] If the pressure stability index of a well-functioning catheter is equal to a preset catheter pressure stability threshold, there is no need to adjust the pressure of the catheter.

[0021] As a further solution, the pressure of each urinary catheter requiring pressure regulation is automatically regulated, and the specific automatic regulation process is:

[0022] The internal pressure of the catheter, the simulated bladder pressure and the simulated urethra pressure corresponding to the first pressure-adjustable catheter at the current simulated use time point are obtained, the simulated bladder pressure and the simulated urethra pressure are averaged, and the result is then differenced with the internal pressure of the catheter. The final value is recorded as the pressure value that needs to be adjusted for the catheter.

[0023] For the first regulated pressure catheter, the pressure reducing device is started, that is, the pressure reducing device releases the pressure value that needs to be adjusted for the catheter, and the pressure data of the area to which the first regulated pressure catheter belongs is obtained and analyzed, specifically including the simulated bladder pressure and the simulated urethra pressure corresponding to the first regulated pressure catheter at the time point of completion of simulated adjustment, the internal pressure of the catheter corresponding to the first regulated pressure catheter at the time point of completion of simulated adjustment is obtained, and the pressure stability index of the first regulated pressure catheter at the time point of completion of simulated adjustment is obtained through comprehensive analysis. If the pressure stability index of the first regulated pressure catheter at the time point of completion of simulated adjustment is equal to the preset catheter pressure stability threshold, the pressure increase is stopped; if the pressure stability index of the first regulated pressure catheter at the time point of completion of simulated adjustment is not equal to the preset catheter pressure stability threshold, the pressure is adjusted again according to the above-mentioned automatic pressure adjustment process.

[0024] For the second regulated pressure catheter, the boosting device is started, that is, the boosting device increases the pressure value that needs to be regulated in the catheter, and obtains and analyzes the pressure data of the area to which the second regulated pressure catheter belongs, specifically including the simulated bladder pressure and the simulated urethra pressure corresponding to the second regulated pressure catheter at the time point when the simulated regulation is completed, obtains the internal pressure of the catheter corresponding to the simulated regulation completion time point of the second regulated pressure catheter, and comprehensively analyzes to obtain the pressure stability index of the second regulated pressure catheter at the time point when the simulated regulation is completed. If the pressure stability index of the second regulated pressure catheter at the time point when the simulated regulation is completed is equal to the preset catheter pressure stability threshold, stop releasing the pressure; if the pressure stability index of the second regulated pressure catheter at the time point when the simulated regulation is completed is not equal to the preset catheter pressure stability threshold, perform pressure regulation again according to the above-mentioned pressure automatic regulation process.

[0025] As a further solution, the specific analysis process of the pressure regulation stability index of each pressure-regulated urinary catheter is as follows:

[0026] Obtain the catheter function index for each catheter requiring pressure regulation.

[0027] The pressure regulation time of each urinary catheter requiring pressure regulation in the pressure regulation cycle is compared with the time corresponding to the pressure regulation cycle to obtain the pressure regulation time ratio of each urinary catheter requiring pressure regulation in the pressure regulation cycle.

[0028] The catheter function index of each catheter requiring pressure regulation, the pressure regulation time ratio, the pressure regulation speed and the average urine output of each catheter requiring pressure regulation within the pressure regulation cycle were comprehensively analyzed to obtain the pressure regulation stability index of each catheter requiring pressure regulation.

[0029] As a further solution, the pressure regulation stability index of each urinary catheter requiring pressure regulation is compared with the pressure regulation stability index threshold of the urinary catheter preset in the pressure regulation database, and finally an early warning prompt is given for the pressure regulation of each urinary catheter requiring pressure regulation. The specific comparison process is:

[0030] The pressure regulation stability index of each urinary catheter requiring pressure regulation is compared with the catheter pressure regulation stability index threshold value preset in the pressure regulation database. If the pressure regulation stability index of a urinary catheter requiring pressure regulation is greater than or equal to the preset catheter pressure regulation stability index threshold value, there is no need to issue an early warning prompt for the pressure regulation of the urinary catheter requiring pressure regulation.

[0031] If the pressure regulation stability index of a catheter requiring pressure regulation is less than the preset catheter pressure regulation stability index threshold, the catheter requiring pressure regulation will be recorded as a pressure regulation warning catheter, and eventually a warning prompt will be issued for the pressure regulation of the pressure regulation warning catheter.

[0032] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0033] (1) The present invention can accurately evaluate the performance of the catheter by detecting the internal information of each silicone catheter in a simulated use state and analyzing the function index of each catheter. By analyzing the function index of the catheter, it can be timely determined whether the function of the catheter meets the standard, thereby reducing the risk of subsequent catheters in the simulated pressure adjustment process.

[0034] (2) The present invention monitors the pressure data of the area to which each well-functioning catheter belongs in real time, and analyzes the pressure stability index of each well-functioning catheter to obtain the pressure abnormality index, so as to timely discover the pressure abnormality that may occur in the catheter during the simulated use, and avoid the catheter failure caused by the pressure abnormality. At the same time, by analyzing the pressure stability index of each well-functioning catheter, the pressure change of each catheter during the simulated use can be understood, and the data basis is provided for the subsequent pressure regulation of the catheter.

[0035] (3) The present invention can automatically adjust the pressure of each catheter that needs pressure regulation, and can adjust the pressure in the catheter according to the simulated bladder pressure and simulated urethral pressure of the catheter during the function determination cycle, so as to keep the pressure of the catheter suitable for the bladder pressure and the urethral pressure, thereby ensuring the safety of the catheter.

[0036] (4) The present invention can timely monitor the changes in catheter pressure by acquiring the adjustment data within each catheter pressure adjustment cycle, and analyze the data to obtain the catheter pressure adjustment stability index, which is compared with the preset catheter pressure adjustment stability index threshold. This can ensure that an alarm is quickly issued when pressure adjustment is abnormal, which helps to improve the timeliness and safety of silicone catheter pressure adjustment.

A person skilled in the art can obtain other drawings based on the following drawings without creative work.

[0038] Figure 1 It is a schematic diagram of system module connection of the present invention. DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 As shown, an embodiment of the present invention provides a technical solution: a pressure adaptive regulation system for a silicone urinary catheter, comprising a silicone urinary catheter monitoring module, a pressure sensing module, a pressure regulation module, a regulation warning module and a pressure regulation database.

[0041] The silicone urinary catheter monitoring module is connected to the pressure sensing module, the pressure sensing module is connected to the pressure regulating module, the pressure regulating module is connected to the regulating warning module, and the pressure regulating database is respectively connected to the silicone urinary catheter monitoring module, the pressure sensing module, the pressure regulating module and the regulating warning module.

[0042] The silicone catheter monitoring module is used to detect and obtain the internal information of each silicone catheter in a simulated state, analyze and obtain the function index of each catheter, and compare it with the catheter function index limit value preset in the pressure regulation database. If the function index of a catheter is less than the preset catheter function index limit value, an early warning prompt is given for the function of the catheter; if the function index of a catheter is greater than or equal to the preset catheter function index limit value, the pressure sensing module is entered.

[0043] The pressure sensing module is used to count a number of catheters corresponding to a catheter function index greater than or equal to a preset catheter function index boundary value, and record them as catheters with good functions, monitor the pressure data of the area to which each catheter with good functions belongs in real time, and analyze them to obtain the pressure stability index of each catheter with good functions.

[0044] The pressure regulating module is used to compare the pressure stability index of each well-functioning catheter with a preset catheter pressure stability threshold, obtain each catheter that needs pressure regulation, and automatically regulate the pressure of each catheter that needs pressure regulation.

[0045] The adjustment warning module is used to obtain the adjustment data of each urinary catheter requiring pressure adjustment within the pressure adjustment cycle, analyze it, obtain the pressure adjustment stability index of each urinary catheter requiring pressure adjustment, and compare it with the urinary catheter pressure adjustment stability index threshold preset in the pressure adjustment database, and finally issue an early warning prompt for the pressure adjustment of each urinary catheter requiring pressure adjustment.

[0046] The pressure regulation database is used to store a preset catheter function index boundary value, a preset catheter pressure stability threshold, a preset catheter pressure regulation stability index threshold, a preset catheter urine reference flow rate, a preset urine reference flow rate, a preset catheter airbag water injection reference content, a preset catheter internal reference pressure, a preset pressure regulation reference value, a weight factor corresponding to the catheter function index preset in the pressure regulation database, a preset pressure regulation reference speed, a preset pressure regulation reference time ratio and a preset urine reference output.

[0047] In this embodiment, the pressure regulation of the silicone urinary catheter is a simulation test of the pressure regulation of the silicone urinary catheter performed by the hospital before the actual use of the silicone urinary catheter, which is usually carried out under simulated human environmental conditions. This simulated environment is as close as possible to the physiological conditions of the patient during actual use to ensure the accuracy and reliability of the simulation test results. Special pressure testing equipment, catheter flow tester, catheter kink stability tester, etc. are used to simulate the working environment of the catheter in actual use. Through the simulation test, the pressure regulation performance of the catheter can be fully evaluated to ensure that it can withstand the expected pressure changes in actual use without leakage, rupture or other performance problems.

[0048] Specifically, the internal information of each silicone urinary catheter in the simulation state includes the airbag water content of each urinary catheter within the function determination period, the average flow rate of catheterized urine, the average flow rate of catheterized urine and the average pressure inside the catheter.

[0049] It should be noted that the airbag water content of each catheter during the function determination period can be obtained by injecting an appropriate amount of physiological saline into the airbag using a sterile syringe with a clear scale, and recording the actual airbag water content injected, thereby obtaining the airbag water content of each catheter during the function determination period; the total flow rate of catheterized urine is measured by using a catheter flow meter, and the amount of urine passing through the catheter during the function determination period is recorded by weighing, and the amount of urine in each catheterization during the function determination period is accumulated to obtain the total flow rate of catheterized urine. The average flow rate of catheterized urine is calculated by measuring the flow rate during the function determination period. During the period, the urine volume and catheterization time of each catheterization are recorded. The urine flow rate of each catheterization can be obtained by calculating the urine volume divided by the catheterization time. The urine flow rates of all times are added up and divided by the total number of catheterizations to obtain the average urine flow rate of catheterization. The average pressure inside the catheter is measured by a pressure sensor to measure the pressure inside the catheter, and the average pressure inside the catheter is calculated by an average function. In this embodiment, the function determination cycle refers to the time period used to detect and determine the function of the catheter, and is randomly arranged according to the actual use status of each catheter.

[0050] Specifically, the specific analysis process of each urinary catheter function index is as follows:

[0051] The balloon water content, average flow rate, average flow rate of catheterized urine and average pressure inside the catheter of each catheter during the function determination period were comprehensively analyzed to obtain the function index of each catheter. The specific analysis method is as follows:

[0052]

[0053] In the formula, F v is the vth catheter function index, v is the number of each catheter, v=1, 2, 3, ...m, m is the total number of catheters, and e is a natural constant.

[0054] NL v is the average flow rate of catheterized urine during the function determination cycle of the vth catheter, which is the ratio of the total amount of urine discharged through the catheter during the function determination cycle to the time period occupied by the function determination cycle.

[0055] ΔNL is the reference urine flow rate for catheterization preset in the pressure regulation database, which refers to setting a reasonable urine flow rate reference value to ensure the patency of the catheter and avoid urine reflux during the catheterization operation.

[0056] NS v is the average flow rate of urine during the function determination cycle of the vth catheter, and is the average speed of urine flow during the function determination cycle of the catheter.

[0057] ΔNS is the urine reference flow rate preset in the pressure regulation database, which refers to setting a reasonable urine flow rate reference value to ensure the patency of the catheter and avoid urine reflux during catheterization.

[0058] NW v The water content of the air bag of the vth urinary catheter during the function determination cycle is the water content of the air bag recorded during the function determination cycle of the urinary catheter.

[0059] ΔNW is the reference water content of the catheter balloon preset in the pressure regulation database, which means setting a reasonable balloon water volume to ensure the fixation of the catheter during the catheterization operation.

[0060] NY v is the average internal pressure of the vth catheter during the function determination cycle, and is the average internal pressure of the catheter recorded during the function determination cycle of the catheter.

[0061] ΔNY is the reference pressure inside the catheter preset in the pressure regulation database, which refers to setting a reasonable pressure inside the catheter to ensure the patency of the catheter and avoid urine reflux during the catheterization operation.

[0062] In this embodiment, when the airbag water injection content of the catheter during the function determination cycle deviates greatly from the preset reference airbag water injection content of the catheter, when the airbag water injection content is insufficient, the catheter cannot be effectively fixed, which will cause the sealing between the catheter and the urethra to decrease, thereby causing urine leakage. If the airbag water injection content is too much, the lumen of the catheter will be squeezed to make its inner diameter thinner, thereby affecting the drainage effect of urine and causing urine to be retained in the bladder; when the average catheterized urine flow rate of the catheter during the function determination cycle deviates greatly from the preset reference catheterized urine flow rate, it indicates that the patency of the catheter is not good or the urine discharge efficiency is low, which will cause urine to be retained in the catheter, causing impurities, crystals or bacteria in the urine to accumulate in the catheter, further aggravating the blockage; when the average catheterized urine flow rate deviates greatly from the reference urine flow rate, it means that the fluid dynamics performance inside the catheter is affected, and the low flow rate may cause urine to flow in the catheter. If the flow is not smooth, the risk of blockage will increase. High flow rate will increase the scouring force of urine on the inner wall of the catheter, which will accelerate the wear and aging of the silicone material. When the average pressure inside the catheter during the function determination period deviates greatly from the preset reference pressure inside the catheter, especially under continuous high or low pressure conditions, the silicone material will accelerate aging, resulting in reduced elasticity and increased brittleness of the silicone, and even possible material rupture. At the same time, long-term exposure to abnormal pressure may cause the structure of the catheter to deform, such as bending, twisting or swelling. These deformations will affect the normal use of the catheter, reduce its drainage effect, and may even cause the catheter to be unable to be smoothly inserted or removed. Therefore, by conducting a detailed analysis of each parameter in each catheter function index, the performance of the catheter can be evaluated more accurately. At the same time, possible problems in the simulated use of the catheter, such as structural deformation, can be discovered, so that corresponding improvement measures can be taken to reduce the risks of subsequent catheters in actual use.

[0063] In this embodiment, each catheter function index is compared with the catheter function index limit value preset in the pressure regulation database. If a catheter function index is less than the preset catheter function index limit value, it means that the performance of the catheter may no longer meet the expected requirements and there is a potential risk of functional failure or performance degradation. In this case, it is necessary to give an early warning prompt for the function. The specific early warning prompt may be to issue a sound alarm and to recycle and repair the catheter.

[0064] If a catheter function index is greater than or equal to the preset catheter function index limit value, it means that the catheter can maintain good performance in the current state and meet the expected usage requirements. At this time, there is no need to issue an early warning prompt for the function of the catheter, but the monitoring of each function index should continue and enter the pressure sensing module.

[0065] In this embodiment, there is a certain correlation and mutual influence between the airbag water content, the average flow rate of catheterized urine, the average flow rate of catheterized urine and the average pressure inside the catheter during the function determination period of each of the above-mentioned catheters. When the airbag water content is moderate, the sealing between the catheter and the urethra is good, and urine can flow out smoothly through the catheter, thereby maintaining a high urine flow rate. When the airbag water content is too much or too little, the sealing between the catheter and the urethra will decrease, resulting in urine leakage, thereby affecting the urine flow rate. At the same time, the airbag water content is too high or too low. The higher the content, the greater the internal pressure of the catheter. The average flow rate of catheterized urine is positively correlated with the average flow rate of catheterized urine. A high average flow rate of catheterized urine means that urine passes through the catheter faster, which will lead to an increase in the internal pressure of the catheter. On the other hand, if the average urine flow rate is low and the flow rate is slow, urine will be retained in the catheter, affecting the function of the catheter. Therefore, by combining multiple parameters, the functional performance of the catheter can be comprehensively evaluated, avoiding the one-sidedness of a single parameter evaluation, ensuring the normal function of the catheter and the safety of the catheter in subsequent use.

[0066] Furthermore, the pressure data of the area to which each well-functioning catheter belongs specifically includes the simulated intra-bladder pressure and the simulated intra-urethral pressure corresponding to each well-functioning catheter at the current simulated use time point.

[0067] It should be noted that the simulated bladder pressure corresponding to the above-mentioned well-functioning catheters at the current simulated use time point is obtained by measuring the pressure generated by the simulated urine delivered to the bladder by the catheter at the current simulated use time point through a pressure sensor, and the simulated urethral pressure is obtained by measuring the pressure of the simulated urethra during the simulated urine flow process of the catheter at the current simulated use time point through a pressure sensor.

[0068] Specifically, the specific analysis process of the pressure stability index of each well-functioning urinary catheter is as follows:

[0069] The internal pressure of each well-functioning catheter corresponding to the current simulated use time point is obtained.

[0070] It should be noted that the internal pressure of the catheter corresponding to the current simulated use time point of the above-mentioned good-function catheters is obtained by measuring the pressure of the catheter at the current simulated use time point through a pressure sensor.

[0071] Comprehensively analyze the internal pressure of the catheter, the simulated bladder pressure, and the simulated urethra pressure corresponding to each well-functioning catheter at the current simulated use time point to obtain the pressure stability index of each well-functioning catheter. The specific analysis method is as follows:

[0072]

[0073] In the formula, SDi is the pressure stability index of the i-th well-functioning urinary catheter, i is the number of each well-functioning urinary catheter, i=1, 2, 3, ...j, j is the total number of well-functioning urinary catheters, and e is a natural constant.

[0074] s i The internal pressure of the catheter corresponding to the i-th well-functioning catheter at the current simulated use time point refers to the internal pressure value measured and recorded for the i-th known well-functioning catheter at the current simulated use time point.

[0075] my i is the simulated bladder pressure corresponding to the i-th well-functioning urinary catheter at the current simulated use time point, and refers to the simulated bladder internal pressure value measured for the i-th known well-functioning urinary catheter at the current simulated use time point.

[0076] ns i is the simulated urethral pressure corresponding to the i-th well-functioning catheter at the current simulated use time point, and refers to the simulated urethral internal pressure value obtained by measuring the i-th known well-functioning catheter at the current simulated use time point.

[0077] It should be explained that when the catheter is correctly inserted into the simulated bladder and opened for drainage, the internal pressure of the catheter should be close to or equal to the simulated bladder pressure. If there is obstruction or stenosis inside the catheter, the internal pressure of the catheter will be higher than the simulated bladder pressure. The simulated bladder pressure should be higher than the simulated urethra pressure to push urine from the bladder to the urethra. If there is obstruction or stenosis in the urethra, the simulated urethra pressure will increase, which may cause the urine to be unable to be discharged smoothly, thereby increasing the simulated bladder pressure. At the same time, during the catheterization process, the relationship between the internal pressure of the catheter and the simulated urethra pressure depends on the position and state of the catheter in the urethra. If the catheter is unobstructed in the urethra, the internal pressure of the catheter should be close to or equal to the simulated urethra pressure (in the area where urine flows). If the catheter encounters obstruction or stenosis in the urethra, the internal pressure of the catheter will be higher than the simulated urethra pressure (in the obstruction or stenosis area). Therefore, the correspondence between the internal pressure of the catheter, the simulated bladder pressure, and the simulated urethra pressure corresponding to each well-functioning catheter at the current simulated use time point is a complex process.

[0078] In this embodiment, the average of the simulated bladder pressure and the simulated urethra pressure is compared with the average of the simulated bladder pressure and the simulated urethra pressure. If the deviation between the average of the simulated bladder pressure and the simulated urethra pressure and the simulated urethra pressure is large, the deviation between the obtained pressure stability index of the well-functioning catheter and the stability index of the ideal state is also large. When the deviation between the average of the simulated bladder pressure and the simulated urethra pressure and the simulated urethra pressure is small, the pressure of the well-functioning catheter is closer to the standard state. If the average of the simulated bladder pressure and the simulated urethra pressure is the same as the simulated urethra pressure, the pressure of the well-functioning catheter reaches a balanced state. At this time, the pressure of the catheter reaches a stable state with the pressure of the simulated bladder and the simulated urethra. Therefore, the pressure stability threshold of the catheter can be obtained as When the pressure stability index of a well-functioning catheter deviates more from the pressure stability threshold of the catheter, the accumulation of sediment inside the catheter will be accelerated, increasing the risk of blockage. If the catheter is subjected to excessive pressure, the internal pressure will increase, affecting the stability of the catheter. At the same time, if the catheter is subjected to an intra-bladder pressure higher than the preset value for a long time, the catheter material will be deformed, affecting the sealing performance of the catheter, and then causing urine leakage, reducing the effectiveness of the catheter. This uneven force will cause the catheter to shift in position or become unstable, affecting the drainage effect of the catheter. Therefore, through a detailed analysis of the various parameters in the pressure stability index of a well-functioning catheter, the pressure anomalies that may occur during the simulated use of the catheter can be discovered in a timely manner, avoiding catheter failures caused by pressure anomalies, and providing a data basis for subsequent pressure regulation of the catheter.

[0079] In this embodiment, the internal pressure of the catheter is used as an important parameter to calculate the pressure stability index and the overall functional index of a well-functioning catheter. The reason why this parameter can be used in different scenarios is that the internal average pressure is a key indicator in both functional evaluation, pressure stability analysis and regulation effect evaluation, which reveals the stability and reliability of the catheter during urine flow. Although the internal average pressure of the catheter is used in both indicators, they correspond to different application scenarios. The functional index focuses on the overall performance of the catheter, and the pressure stability index focuses on the stability of a well-functioning catheter.

[0080] Furthermore, the pressure stability index of each well-functioning urinary catheter is compared with a preset urinary catheter pressure stability threshold to obtain each urinary catheter that needs pressure regulation. The specific comparison process is:

[0081] If the pressure stability index of a well-functioning catheter is not equal to the preset catheter pressure stability threshold, the catheter is recorded as a catheter requiring pressure regulation.

[0082] Among them, if the pressure stability index of a well-functioning catheter is less than the preset catheter pressure stability threshold, the catheter requiring pressure regulation is recorded as the first pressure-regulated catheter; if the pressure stability index of a well-functioning catheter is greater than the preset catheter pressure stability threshold, the catheter requiring pressure regulation is recorded as the second pressure-regulated catheter.

[0083] It should be noted that when the pressure stability index of a well-functioning catheter is less than the preset catheter pressure stability threshold, it means that the pressure inside the catheter may be too low, insufficient to meet the current pressure in the bladder and urethra, resulting in abnormal drainage of urine. If the pressure stability index of a well-functioning catheter is greater than the preset catheter pressure stability threshold, it means that the pressure inside the catheter is too high, which will increase the risk of damage to the urethra and bladder.

[0084] If the pressure stability index of a well-functioning catheter is equal to a preset catheter pressure stability threshold, there is no need to adjust the pressure of the catheter.

[0085] It should be noted that if the pressure stability index of a well-functioning catheter is equal to the preset catheter pressure stability threshold, it means that the pressure inside the catheter is within a safe and stable range, neither too high nor too low. Therefore, the well-functioning catheter does not need to perform any pressure adjustment operation and maintains its current pressure state.

[0086] Specifically, the pressure of each urinary catheter requiring pressure regulation is automatically regulated, and the specific automatic regulation process is as follows:

[0087] The internal pressure of the catheter, the simulated bladder pressure and the simulated urethra pressure corresponding to the first pressure-adjustable catheter at the current simulated use time point are obtained, the simulated bladder pressure and the simulated urethra pressure are averaged, and the result is then differenced with the internal pressure of the catheter. The final value is recorded as the pressure value that needs to be adjusted for the catheter.

[0088] For the first regulated pressure catheter, the pressure reducing device is started, that is, the pressure reducing device releases the pressure value that needs to be adjusted for the catheter, and the pressure data of the area to which the first regulated pressure catheter belongs is obtained and analyzed, specifically including the simulated bladder pressure and the simulated urethra pressure corresponding to the first regulated pressure catheter at the time point of completion of simulated adjustment, the internal pressure of the catheter corresponding to the first regulated pressure catheter at the time point of completion of simulated adjustment is obtained, and the pressure stability index of the first regulated pressure catheter at the time point of completion of simulated adjustment is obtained through comprehensive analysis. If the pressure stability index of the first regulated pressure catheter at the time point of completion of simulated adjustment is equal to the preset catheter pressure stability threshold, the pressure increase is stopped; if the pressure stability index of the first regulated pressure catheter at the time point of completion of simulated adjustment is not equal to the preset catheter pressure stability threshold, the pressure is adjusted again according to the above-mentioned automatic pressure adjustment process.

[0089] For the second regulated pressure catheter, the boosting device is started, that is, the boosting device increases the pressure value that needs to be regulated in the catheter, and obtains and analyzes the pressure data of the area to which the second regulated pressure catheter belongs, specifically including the simulated bladder pressure and the simulated urethra pressure corresponding to the second regulated pressure catheter at the time point when the simulated regulation is completed, obtains the internal pressure of the catheter corresponding to the simulated regulation completion time point of the second regulated pressure catheter, and comprehensively analyzes to obtain the pressure stability index of the second regulated pressure catheter at the time point when the simulated regulation is completed. If the pressure stability index of the second regulated pressure catheter at the time point when the simulated regulation is completed is equal to the preset catheter pressure stability threshold, stop releasing the pressure; if the pressure stability index of the second regulated pressure catheter at the time point when the simulated regulation is completed is not equal to the preset catheter pressure stability threshold, perform pressure regulation again according to the above-mentioned pressure automatic regulation process.

[0090] In this embodiment, the above-mentioned well-functioning catheter includes a first pressure-regulating catheter and a second pressure-regulating catheter. Therefore, the method for obtaining the simulated intra-bladder pressure and the simulated intra-urethral pressure corresponding to the time point of completion of the simulated regulation of the first pressure-regulating catheter, and the simulated intra-bladder pressure, the simulated intra-urethral pressure and the internal pressure of the catheter corresponding to the time point of completion of the simulated regulation of the second pressure-regulating catheter are the same as the method for obtaining the simulated intra-bladder pressure, the simulated intra-urethral pressure and the internal pressure of the catheter corresponding to the current simulated use time point of the above-mentioned well-functioning catheters; the pressure stability index of the first pressure-regulating catheter in the current pressure regulation cycle, the pressure stability index of the second pressure-regulating catheter in the current pressure regulation cycle and the analysis method of the pressure stability index of the above-mentioned well-functioning catheters are the same.

[0091] It should be noted that, when the pressure stability index of the first regulating pressure catheter in the current pressure regulation cycle is equal to the preset catheter pressure stability threshold, it means that by increasing the internal pressure of the first regulating pressure catheter, the pressure corresponding to the first regulating pressure catheter at the simulation regulation completion time point is within a safe and stable range. Therefore, the first regulating pressure catheter does not need to perform a pressure increase adjustment operation on the pressure corresponding to the simulation regulation completion time point, and maintains its current pressure state; when the pressure stability index of the second regulating pressure catheter in the current pressure regulation cycle is equal to the preset catheter pressure stability threshold, it means that by releasing the internal pressure of the second regulating pressure catheter, the pressure corresponding to the second regulating pressure catheter at the simulation regulation completion time point is within a safe and stable range. Therefore, the second regulating pressure catheter does not need to perform a release adjustment operation on the pressure corresponding to the simulation regulation completion time point, and maintains its current pressure state, wherein the simulation regulation completion time point is the next time point for pressure regulation of the above-mentioned current simulation use time point.

[0092] Furthermore, the regulation data of each urinary catheter requiring pressure regulation within the pressure regulation cycle specifically includes the pressure regulation speed, the average urine discharge volume and the pressure regulation duration of each urinary catheter requiring pressure regulation within the pressure regulation cycle.

[0093] It should be noted that the pressure regulation speed of each of the above-mentioned catheters requiring pressure regulation within the pressure regulation cycle is obtained by real-time monitoring of the pressure changes of the catheter within the pressure regulation cycle through a pressure sensor, and the pressure regulation speed is obtained by recording the change in pressure of each adjustment and performing ratio processing on the change in pressure of each adjustment and the duration of each pressure regulation. The average urine discharge is obtained by collecting the discharged urine through a urine collection container, and using an accurate timing device to record the time. The total amount of urine collected is divided by the recorded time period to obtain the average urine discharge. The pressure regulation duration is obtained by recording the time difference from the start to the end of the regulation process through a timer. The pressure regulation cycle is the time period required for the entire process from the start of catheter pressure regulation to the end of catheter pressure regulation. In this embodiment, it is arranged according to the actual pressure of each catheter, and the pressure regulation cycle includes but is not limited to the above-mentioned current simulated use time point and simulated regulation completion time point.

[0094] Specifically, the specific analysis process of the pressure regulation stability index of each urinary catheter requiring pressure regulation is as follows:

[0095] Obtain the catheter function index for each catheter requiring pressure regulation.

[0096] It should be explained that, in this example, each catheter includes a well-functioning catheter and each catheter requiring pressure regulation. Therefore, each catheter function index includes the catheter function index of each catheter requiring pressure regulation. The catheter function index is a comprehensive evaluation indicator, which combines multiple performance parameters and can comprehensively reflect the effectiveness of the catheter in actual use. It has a significant impact on the process of catheter pressure regulation and is directly related to the urine discharge rate of the catheter after pressure regulation.

[0097] The pressure regulation time of each urinary catheter requiring pressure regulation in the pressure regulation cycle is compared with the time corresponding to the pressure regulation cycle to obtain the pressure regulation time ratio of each urinary catheter requiring pressure regulation in the pressure regulation cycle.

[0098] It should be explained that the pressure regulation time of the above-mentioned catheters requiring pressure regulation within the pressure regulation cycle refers to the time period during which the catheter actually performs pressure regulation within the pressure regulation cycle, and the duration corresponding to the pressure regulation cycle refers to the duration of the entire pressure regulation process, including the preparation time before pressure regulation, the actual pressure regulation time, and the stabilization time after regulation, etc. By comparing the pressure regulation time with the pressure regulation cycle duration, the performance of the catheter in pressure regulation can be evaluated.

[0099] The catheter function index of each catheter requiring pressure regulation, the pressure regulation time ratio, the pressure regulation speed and the average urine output of each catheter requiring pressure regulation within the pressure regulation cycle were comprehensively analyzed to obtain the pressure regulation stability index of each catheter requiring pressure regulation.

[0100] In this embodiment, there is a complex data change relationship between the catheter function index of each of the above-mentioned catheters requiring pressure regulation, the pressure regulation time ratio, the pressure regulation speed and the average urine discharge volume of each of the catheters requiring pressure regulation within the pressure regulation cycle. A catheter with a high function index often has better pressure regulation ability and therefore has a higher pressure regulation time ratio. A catheter with a high function index usually has a faster pressure regulation speed. An efficient catheter usually completes pressure regulation in a shorter time, thereby having a higher pressure regulation time ratio and a faster pressure regulation speed. A catheter that can stably regulate pressure helps to urinate better, thereby having a higher average urine discharge volume.

[0101] The specific analysis method for obtaining the pressure regulation stability index of each urinary catheter requiring pressure regulation is as follows:

[0102]

[0103] In the formula, θ n is the pressure regulation stability index of the nth catheter requiring pressure regulation, n is the number of each catheter requiring pressure regulation, n=1, 2, 3, ...w, w is the total number of catheters requiring pressure regulation, e is a natural constant, F n It is the catheter function index of the nth catheter requiring pressure regulation.

[0104] u1 is the weight factor corresponding to the catheter function index preset in the pressure regulation database. The weight factor corresponding to the catheter function index can be directly obtained from the pressure regulation database, and the corresponding relationship can be a preset mapping relationship. For example, a mapping set is formed according to the historical catheter function index and the weight factor corresponding to the catheter function index, and the real-time catheter function index is input into the mapping set to obtain the weight factor corresponding to the catheter function index. The mapping relationship can be one-to-one or many-to-one. At the same time, in this example, its value range is [0, 1].

[0105] jc n The pressure regulation speed of the nth urinary catheter requiring pressure regulation during the pressure regulation cycle is the speed at which the catheter adjusts the pressure in the urethra.

[0106] Δjc is a pressure regulation reference speed preset in the pressure regulation database, and refers to a reference value of a pressure regulation speed preset in the pressure regulation database.

[0107] ts n It is the pressure regulation time ratio of the nth urinary catheter requiring pressure regulation within the pressure regulation cycle, which refers to the ratio of the pressure regulation time length to the time length corresponding to the pressure regulation cycle.

[0108] Δts is a pressure regulation reference time ratio preset in the pressure regulation database, and refers to a pressure regulation time ratio reference value preset in the pressure regulation database.

[0109] pn n It is the average amount of urine discharged during the pressure regulation cycle of the nth urinary catheter requiring pressure regulation, which refers to the average amount of urine discharged during the pressure regulation cycle.

[0110] Δpn is a reference amount of urine discharged preset in the pressure regulation database, and refers to a reference amount of urine discharged preset in the pressure regulation database.

[0111] In this embodiment, when the catheter function index corresponding to the pressure regulation cycle of the catheter requiring pressure regulation is low, it means that the pressure regulation efficiency of the catheter is not high, which will lead to a decrease in the urine discharge efficiency, thereby affecting the pressure regulation stability index of each catheter requiring pressure regulation. When the actual pressure regulation time ratio is lower than the preset reference time ratio, it means that the catheter does not perform effective pressure regulation for most of the time in the pressure regulation cycle, which may cause large fluctuations in the pressure in the urethra and decreased stability. When the pressure regulation speed deviates greatly from the preset pressure regulation reference speed, it will affect the catheter's precise control of the pressure in the urethra, thereby reducing the regulation accuracy. When the average urine discharge volume is far lower than the reference value, excessive urine accumulates in the urethra, increasing the pressure in the urethra. Therefore, through a detailed analysis of each parameter in the pressure regulation stability index of each catheter requiring pressure regulation, potential safety hazards that may exist during the use of the catheter can be discovered in a timely manner, which helps to avoid damage, leakage or reflux of the catheter due to improper pressure, thereby improving the safety of the use of the catheter.

[0112] Furthermore, the pressure regulation stability index of each urinary catheter requiring pressure regulation is compared with the pressure regulation stability index threshold of the urinary catheter preset in the pressure regulation database, and finally an early warning prompt is given for the pressure regulation of each urinary catheter requiring pressure regulation. The specific comparison process is:

[0113] The pressure regulation stability index of each urinary catheter requiring pressure regulation is compared with the catheter pressure regulation stability index threshold value preset in the pressure regulation database. If the pressure regulation stability index of a urinary catheter requiring pressure regulation is greater than or equal to the preset catheter pressure regulation stability index threshold value, there is no need to issue an early warning prompt for the pressure regulation of the urinary catheter requiring pressure regulation.

[0114] It needs to be explained that when a catheter pressure regulation index is greater than or equal to the preset catheter pressure regulation stability index threshold, it means that the pressure-regulated catheter that requires pressure regulation has reached a stable and safe state through pressure regulation. In this case, there is no need to give an early warning prompt for the pressure regulation of the catheter because it has met the preset safety standards. At the same time, in this embodiment, the termination pressure corresponding to the catheter pressure regulation index being greater than or equal to the preset catheter pressure regulation stability index threshold can be reset to the initial pressure regulation value of the catheter that requires pressure regulation. In subsequent actual use, if the catheter pressure has not changed significantly, there is no need to perform additional pressure regulation operations.

[0115] If the pressure regulation stability index of a catheter requiring pressure regulation is less than the preset catheter pressure regulation stability index threshold, the catheter requiring pressure regulation will be recorded as a pressure regulation warning catheter, and eventually a warning prompt will be issued for the pressure regulation of the pressure regulation warning catheter.

[0116] It needs to be explained that when a catheter pressure regulation index is less than the preset catheter pressure regulation stability index threshold, it means that the pressure-regulated catheter that needs pressure regulation has not yet reached the preset safety standard, and there may be a risk of overpressure or underpressure. The catheter that needs pressure regulation needs to be recorded as a pressure regulation warning catheter and a warning prompt is given. In this embodiment, the warning prompt is specifically: the pressure of the catheter that is automatically adjusted is at risk of overpressure or underpressure, and the pressure reducing device or the pressurizing device of the pressure regulation warning catheter needs to be re-inspected immediately.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined in this specification, they should all fall within the protection scope of the present invention.
