Description

Technical Field

[0001] The present invention relates to the technical field of silicone catheter pressure regulation, and particularly to a pressure self-adaptive regulation system for silicone catheters. Background Art

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

[0003] For example, the invention patent with the publication number CN104922777B discloses a catheter with adjustable head-end opening size, which includes a straight catheter. Three sliding guide wires are evenly arranged inside the side wall of the straight catheter. The front ends of the guide wires are connected to the catheter head, and an adjustment switch for adjusting the telescopic length of the guide wires is provided at the rear section of the catheter. When inserting the catheter, the head-end opening can be slightly adjusted smaller, and after indwelling, the opening can be adjusted larger or closed according to needs.

[0004] For example, the invention patent with the publication number CN118320279A discloses a catheter, which includes a catheter main body and a flexible pressure sensing unit. The flexible pressure sensing unit is coated on the part of the catheter main body inserted into the bladder. After the catheter main 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 a pressure monitoring device outside the body. Medical staff can obtain the pressure value in the bladder through the pressure monitoring device to judge whether there is a blockage problem with the catheter.

[0005] However, in the process of implementing the technical solutions of the present invention in the embodiments of the present application, it is found that the above technologies have at least the following technical problems:

[0006] In existing silicone catheter pressure regulation systems, manual adjustment of the catheter by medical staff is required, and it is impossible to respond in real time to changes in bladder pressure. When the bladder pressure suddenly changes, the pressure of the catheter cannot be adjusted in time, resulting in unsmooth urine drainage. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the present invention provides a pressure self-adaptive regulation system for silicone catheters, which can effectively solve the problems involved in the above background art.

[0008] To achieve the above object, the present invention is realized through the following technical solutions: A pressure adaptive adjustment system for a silicone catheter includes a silicone catheter monitoring module, which is used to detect and obtain the internal information of each silicone catheter in the simulated state, analyze to obtain the function index of each catheter, and compare it with the defined value of the catheter function index preset in the pressure adjustment database. If the function index of a certain catheter is less than the preset defined value of the catheter function index, a warning prompt for the function of the catheter is given. If the function index of a certain catheter is greater than or equal to the preset defined value of the catheter function index, it enters the pressure sensing module; The pressure sensing module is used to count several catheters corresponding to the catheter function index greater than or equal to the preset defined value of the catheter function index, and record them as each functionally good catheter, and real-time monitor the pressure data of the area where each functionally good catheter belongs, and perform analysis to obtain the pressure stability index of each functionally good catheter; The pressure adjustment module is used to compare the pressure stability index of each functionally good catheter with the preset catheter pressure stability threshold to obtain each catheter that needs pressure adjustment, and automatically adjust the pressure of each catheter that needs pressure adjustment; The adjustment warning module is used to obtain the adjustment data of each catheter that needs pressure adjustment during the pressure adjustment period, perform analysis to obtain the pressure adjustment stability index of each catheter that needs pressure adjustment, and compare it with the preset catheter pressure adjustment stability index threshold in the pressure adjustment database, and finally give a warning prompt for the pressure adjustment of each catheter that needs pressure adjustment.

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

[0010] Divide the total urine flow of each catheter during the function determination period by the total number of urine drainage times to obtain the average urine flow of each catheter during the function determination period.

[0011] Comprehensively analyze the balloon water injection content, average urine flow, average urine flow velocity, and average internal pressure of each catheter during the function determination period to obtain the function index of each catheter. The specific analysis method is as follows:

[0012]

[0013] In the formula, F v is the function index of the v-th catheter, v is the number of each catheter, v = 1, 2, 3,... m, m is the total number of catheters, e is the natural constant, NL v is the average urine flow of the v-th catheter during the function determination period, ΔNL is the reference urine flow preset in the pressure adjustment database, NS v is the average urine flow velocity of the v-th catheter during the function determination period, ΔNS is the reference urine flow velocity preset in the pressure adjustment database, NW vThe balloon water injection content of the v-th urinary catheter within the function determination period, ΔNW is the reference balloon water injection content of the urinary catheter preset in the pressure regulation database, NY v is the average internal pressure of the v-th urinary catheter within the function determination period, and ΔNY is the reference internal pressure of the urinary 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] Obtain the internal pressure of each well-functioning urinary catheter corresponding to the current simulated usage time point.

[0016] Comprehensively analyze the internal pressure of each well-functioning urinary catheter corresponding to the current simulated usage time point, the simulated bladder internal pressure, and the simulated urethral internal pressure to obtain the pressure stability index of each well-functioning urinary catheter.

[0017] As a further solution, the specific comparison process of comparing the pressure stability index of each well-functioning urinary catheter with the preset urinary catheter pressure stability threshold to obtain each urinary catheter that requires pressure regulation is as follows:

[0018] If the pressure stability index of a well-functioning urinary catheter is not equal to the preset urinary catheter pressure stability threshold, then mark this urinary catheter as a urinary catheter that requires pressure regulation.

[0019] Among them, if the pressure stability index of a well-functioning urinary catheter is less than the preset urinary catheter pressure stability threshold, then mark this urinary catheter that requires pressure regulation as the first pressure regulation catheter, and if the pressure stability index of a well-functioning urinary catheter is greater than the preset urinary catheter pressure stability threshold, then mark this urinary catheter that requires pressure regulation as the second pressure regulation catheter.

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

[0021] As a further solution, the specific automatic adjustment process of automatically adjusting the pressure of each urinary catheter that requires pressure regulation is as follows:

[0022] Obtain the internal pressure of the first pressure regulation catheter corresponding to the current simulated usage time point, the simulated bladder internal pressure, and the simulated urethral internal pressure, perform an average value process on the simulated bladder internal pressure and the simulated urethral internal pressure, and then perform a difference process on the obtained result and the internal pressure of the urinary catheter. The finally obtained value is recorded as the pressure value that the urinary catheter needs to be adjusted.

[0023] For the first pressure-adjustable catheter, start the decompression device, i.e., the decompression device releases the pressure value to be adjusted for the catheter, and obtains and analyzes the pressure data of the area where the first pressure-adjustable catheter is located, specifically including the simulated bladder pressure and the simulated urethral pressure corresponding to the first pressure-adjustable catheter at the simulated adjustment completion time point, obtains the internal pressure of the catheter corresponding to the first pressure-adjustable catheter at the simulated adjustment completion time point, and comprehensively analyzes to obtain the pressure stability index corresponding to the first pressure-adjustable catheter at the simulated adjustment completion time point. If the pressure stability index corresponding to the first pressure-adjustable catheter at the simulated adjustment completion time point is equal to the preset catheter pressure stability threshold, stop increasing the pressure. If the pressure stability index corresponding to the first pressure-adjustable catheter at the simulated adjustment completion time point is not equal to the preset catheter pressure stability threshold, perform pressure adjustment again according to the above pressure automatic adjustment process.

[0024] For the second pressure-adjustable catheter, start the pressurization device, i.e., the pressurization device increases the pressure value to be adjusted for the catheter, and obtains and analyzes the pressure data of the area where the second pressure-adjustable catheter is located, specifically including the simulated bladder pressure and the simulated urethral pressure corresponding to the second pressure-adjustable catheter at the simulated adjustment completion time point, obtains the internal pressure of the catheter corresponding to the second pressure-adjustable catheter at the simulated adjustment completion time point, and comprehensively analyzes to obtain the pressure stability index corresponding to the second pressure-adjustable catheter at the simulated adjustment completion time point. If the pressure stability index corresponding to the second pressure-adjustable catheter at the simulated adjustment completion time point is equal to the preset catheter pressure stability threshold, stop releasing the pressure. If the pressure stability index corresponding to the second pressure-adjustable catheter at the simulated adjustment completion time point is not equal to the preset catheter pressure stability threshold, perform pressure adjustment again according to the above pressure automatic adjustment process.

[0025] As a further solution, the specific analysis process of the pressure adjustment stability index of each catheter to be pressure-adjusted is as follows:

[0026] Obtain the catheter function index of each catheter to be pressure-adjusted.

[0027] Compare the pressure adjustment duration of each catheter to be pressure-adjusted during the pressure adjustment cycle with the duration corresponding to the pressure adjustment cycle to obtain the pressure adjustment time ratio of each catheter to be pressure-adjusted during the pressure adjustment cycle.

[0028] Comprehensively analyze the catheter function index of each catheter to be pressure-adjusted, the pressure adjustment time ratio, the pressure adjustment speed, and the average urine output of each catheter to be pressure-adjusted during the pressure adjustment cycle to obtain the pressure adjustment stability index of each catheter to be pressure-adjusted.

[0029] As a further solution, the pressure regulation stability indicators of each catheter requiring pressure regulation are compared with the threshold values of the catheter pressure regulation stability indicators preset in the pressure regulation database, and finally, a warning prompt for the pressure regulation of each catheter requiring pressure regulation is given. The specific comparison process is as follows:

[0030] The pressure regulation stability indicators of each catheter requiring pressure regulation are compared with the threshold values of the catheter pressure regulation stability indicators preset in the pressure regulation database. If the pressure regulation stability indicator of a certain catheter requiring pressure regulation is greater than or equal to the preset threshold value of the catheter pressure regulation stability indicator, there is no need to give a warning prompt for the pressure regulation of this catheter requiring pressure regulation.

[0031] If the pressure regulation stability indicator of a certain catheter requiring pressure regulation is less than the preset threshold value of the catheter pressure regulation stability indicator, this catheter requiring pressure regulation is recorded as a catheter with a pressure regulation warning, and finally, a warning prompt for the pressure regulation of this catheter with a pressure regulation warning needs to be given.

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

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

[0034] (2) By real-time monitoring the pressure data of the areas where each catheter with good function is located and analyzing to obtain the pressure stability indicators of each catheter with good function, the present invention can detect in time the possible pressure abnormalities that may occur during the simulated use of the catheter, avoid catheter failures caused by pressure abnormalities, and at the same time, by analyzing the pressure stability indicators of each catheter with good function, it can understand the pressure change situation of each catheter during the simulated use process, providing a data basis for the subsequent pressure regulation of the catheter.

[0035] (3) By automatically regulating the pressure of each catheter requiring pressure regulation, the present invention can adjust the pressure inside the catheter according to the simulated bladder pressure and simulated urethral pressure of the catheter within the function determination period, keep the pressure of the catheter applicable to the bladder pressure and urethral pressure, and ensure the safety of the catheter.

[0036] (4) By obtaining the adjustment data within each catheter pressure adjustment cycle, the present invention can timely monitor the changes in the catheter pressure, analyze this data to obtain the catheter pressure adjustment stability index, and compare it with the preset catheter pressure adjustment stability index threshold, which can ensure that an alarm is quickly issued when abnormal pressure adjustment occurs, and is helpful to improve the timeliness and safety of the silicone catheter pressure adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be further described with reference to the accompanying drawings. However, the embodiments in the drawings do not constitute any limitation to the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained according to the following drawings.

[0038] Figure 1 It is a schematic diagram of the connection of the system modules of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0040] Refer to Figure 1 As shown, the embodiments of the present invention provide a technical solution: a pressure adaptive adjustment system for a silicone catheter, including a silicone catheter monitoring module, a pressure sensing module, a pressure adjustment module, an adjustment warning module, and a pressure adjustment database.

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

[0042] The silicone catheter monitoring module is used to detect and obtain the internal information of each silicone catheter in the simulation state, analyze and obtain the function index of each catheter, and compare it with the preset catheter function index boundary value in the pressure adjustment database. If the function index of a certain catheter is less than the preset catheter function index boundary value, a warning prompt for the function of the catheter is given. If the function index of a certain catheter is greater than or equal to the preset catheter function index boundary value, it enters the pressure sensing module.

[0043] The pressure sensing module is used to count several catheters corresponding to the catheter function index greater than or equal to the preset catheter function index definition value, and record them as each catheter with good function. It real-time monitors the pressure data of the area where each catheter with good function belongs, and conducts analysis to obtain the pressure stability index of each catheter with good function.

[0044] The pressure adjustment module is used to compare the pressure stability index of each catheter with good function with the preset catheter pressure stability threshold value to obtain each catheter requiring pressure adjustment, and automatically adjust the pressure of each catheter requiring pressure adjustment.

[0045] The adjustment warning module is used to obtain the adjustment data of each catheter requiring pressure adjustment during the pressure adjustment period, conduct analysis to obtain the pressure adjustment stability index of each catheter requiring pressure adjustment, and compare it with the catheter pressure adjustment stability index threshold value preset in the pressure adjustment database, and finally give a warning prompt for the pressure adjustment of each catheter requiring pressure adjustment.

[0046] The pressure adjustment database is used to store the preset catheter function index definition value, the preset catheter pressure stability threshold value, the preset catheter pressure adjustment stability index threshold value, the preset catheter urine reference flow rate, the preset urine reference flow velocity, the preset catheter balloon water injection reference content, the preset catheter internal reference pressure, the preset pressure adjustment reference value, the weight factor corresponding to the catheter function index preset in the pressure adjustment database, the preset pressure adjustment reference speed, the preset pressure adjustment reference time ratio, and the preset urine reference discharge volume.

[0047] In this embodiment, the pressure adjustment of the silicone catheter is a simulation test of the pressure adjustment of the silicone catheter before its actual use in the hospital. Usually, it is carried out under the simulated human environment 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 test equipment, catheter flow testers, catheter kink stability testers, etc. are used to simulate the working environment of the catheter during actual use. Through the simulation test, the pressure adjustment performance of the catheter can be comprehensively evaluated to ensure that it can withstand the expected pressure changes during actual use and will not have problems such as leakage, rupture or other performance issues.

[0048] Specifically, the internal information of each silicone catheter in the simulated state specifically includes the balloon water injection content, the average urine drainage flow rate, the average urine drainage flow velocity, and the average internal pressure of the catheter during the function determination period of each catheter.

[0049] It should be noted that for the balloon water injection content of each of the above catheters during the function determination period, an appropriate amount of physiological saline can be injected into the balloon using a sterile syringe with clear graduations, and the actual balloon water injection content injected is recorded, thereby obtaining the balloon water injection content of each catheter during the function determination period; the total urine flow of catheterization is measured using a catheter flow meter, and the urine volume passing through the catheter during the function determination period is recorded by the weighing method. The urine volumes of each catheterization during the function determination period are accumulated to obtain the total urine flow of catheterization. The average urine flow velocity of catheterization is obtained by recording the urine volume and the catheterization duration of each catheterization during the function determination period. By calculating the urine volume divided by the catheterization duration, the urine flow velocity of each catheterization can be obtained. Adding up the urine flow velocities of all times and dividing by the total number of catheterizations can obtain the average urine flow velocity of catheterization. The average internal pressure of the catheter is measured using a pressure sensor and the average internal pressure of the catheter is calculated through an average function. In this embodiment, the function determination period refers to the time period used for detecting and determining the function of the catheter, which is randomly arranged according to the actual usage conditions of each catheter.

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

[0051] The balloon water injection content, the average urine flow of catheterization, the average urine flow velocity of catheterization, and the average internal pressure of the catheter during the function determination period of each catheter are 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 function index of the v-th catheter, v is the number of each catheter, v = 1, 2, 3,... m, m is the total number of catheters, and e is the natural constant.

[0054] NL v is the average urine flow of catheterization of the v-th catheter during the function determination period, which refers to the ratio of the total urine volume discharged through the catheter during the function determination period of the catheter to the time period occupied by the function determination period.

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

[0056] NS v is the average urine flow velocity of catheterization of the v-th catheter during the function determination period, which refers to the average velocity of urine flow in the catheter during the function determination period.

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

[0058] NW v NW is the water injection content of the balloon of the v-th catheter during the function determination period, which refers to the water injection content in the balloon recorded by the catheter during the function determination period.

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

[0060] NY v NY is the average internal pressure of the v-th catheter during the function determination period, which refers to the average value of the internal pressure of the catheter recorded during the function determination period.

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

[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 among the balloon injection content, the average urine flow rate during catheterization, the average urine flow velocity during catheterization, and the average internal pressure of the catheter within the function determination period. When the balloon injection content is appropriate, the sealing between the catheter and the urethra is good, and urine can flow out smoothly through the catheter, thus maintaining a relatively high urine flow rate. When the balloon injection content is too much or too little, the sealing between the catheter and the urethra will decrease, resulting in urine leakage, which will in turn affect the urine flow rate. At the same time, the more the balloon injection content, the greater the internal pressure of the catheter. The average urine flow rate during catheterization is positively correlated with the average urine flow velocity during catheterization. A high average urine flow velocity during catheterization 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 velocity is slow, urine will stagnate in the catheter, affecting the function of the catheter. Therefore, by comprehensively considering multiple parameters, the functional performance of the catheter can be evaluated comprehensively, avoiding the one-sidedness of single-parameter evaluation, ensuring the normal function of the catheter, and the safety of the catheter during subsequent use.

[0066] Further, the pressure data of the regions where the catheters with good functions are located specifically include the simulated bladder internal pressure and the simulated urethra internal pressure corresponding to each catheter with good function at the current simulated use time point.

[0067] It should be noted that the simulated bladder internal pressure corresponding to each catheter with good function at the current simulated use time point is obtained by measuring the pressure generated by the simulated urine transported by the catheter to the bladder at the current simulated use time point with a pressure sensor, and the simulated urethra internal pressure is obtained by measuring the pressure of the simulated urethra during the simulated urine flow process at the current simulated use time point with a pressure sensor.

[0068] Specifically, the specific analysis process of the pressure stability index of each catheter with good function is as follows:

[0069] Obtain the internal pressure of the catheter corresponding to each catheter with good function at the current simulated use time point.

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

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

[0072]

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

[0074] sn i is the internal pressure of the i-th functional urinary catheter corresponding to the current simulated usage time point, which refers to measuring and recording the internal pressure value of the i-th known functional urinary catheter at the current simulated usage time point.

[0075] my i is the simulated bladder internal pressure of the i-th functional urinary catheter corresponding to the current simulated usage time point, which refers to the measured simulated bladder internal pressure value for the i-th known functional urinary catheter at the current simulated usage time point.

[0076] ns i is the simulated urethral internal pressure of the i-th functional urinary catheter corresponding to the current simulated usage time point, which refers to the measured simulated urethral internal pressure value for the i-th known functional urinary catheter at the current simulated usage time point.

[0077] It should be explained that when the urinary catheter is correctly inserted into the simulated bladder and the drainage is opened, the internal pressure of the urinary catheter should be close to or equal to the simulated bladder internal pressure. If there is an obstruction or stenosis inside the urinary catheter, the internal pressure of the urinary catheter will be higher than the simulated bladder internal pressure. The simulated bladder internal pressure should be higher than the simulated urethral internal pressure to push urine from the bladder to the urethra. If there is an obstruction or stenosis in the urethra, the simulated urethral internal pressure will increase, which may cause the urine to not be discharged smoothly, thereby increasing the simulated bladder internal pressure. At the same time, during the urine drainage process of the urinary catheter, the relationship between the internal pressure of the urinary catheter and the simulated urethral internal pressure depends on the position and state of the urinary catheter in the urethra. If the urinary catheter is unobstructed in the urethra, the internal pressure of the urinary catheter should be close to or equal to the simulated urethral internal pressure (in the area where urine flows). If the urinary catheter encounters an obstruction or stenosis in the urethra, the internal pressure of the urinary catheter will be higher than the simulated urethral internal pressure (in the obstruction or stenosis area). Therefore, the corresponding relationship among the internal pressure of the urinary catheter, the simulated bladder internal pressure, and the simulated urethral internal pressure of each functional urinary catheter corresponding to the current simulated usage time point is a complex process.

[0078] In this embodiment, the mean value of the simulated intravesical pressure and the simulated intraurethral pressure is compared with the mean value of the simulated intravesical pressure and the simulated intraurethral pressure. When the deviation between the mean value of the simulated intravesical pressure and the simulated intraurethral pressure and the simulated intraurethral pressure is large, the deviation between the pressure stability index of the well-functioning catheter and the stability index in the ideal state is also large. When the deviation between the mean value of the simulated intravesical pressure and the simulated intraurethral pressure and the simulated intraurethral pressure is small, the pressure of the well-functioning catheter is closer to the standard state. When the mean value of the simulated intravesical pressure and the simulated intraurethral pressure is the same as the simulated intraurethral pressure, the pressure of the well-functioning catheter reaches a balanced state. At this time, the pressure of the catheter and the pressure of the simulated bladder and simulated urethra reach a stable state. Thus, the pressure stability threshold of the catheter can be obtained as When the deviation degree between the pressure stability index of the well-functioning catheter and the catheter pressure stability threshold is larger, it will accelerate the accumulation of deposits inside the catheter and increase the risk of blockage. If the catheter bears too much pressure, it will cause the internal pressure to rise, affecting the stability of the catheter. At the same time, if the catheter bears the intravesical pressure higher than the preset value for a long time, it will cause the deformation of the catheter material, affecting the sealing performance of the catheter, and then leading to urine leakage, reducing the use effect of the catheter. This uneven force will cause the displacement or unstable fixation of the catheter position, thus affecting the drainage effect of the catheter. Therefore, by analyzing each parameter in the pressure stability index of the well-functioning catheter in detail, it is possible to timely detect the possible pressure abnormalities during the simulated use of the catheter, avoid catheter failures caused by pressure abnormalities, and provide a data basis for the subsequent pressure adjustment of the catheter.

[0079] In this embodiment, the internal pressure of the catheter, as an important parameter, is used in calculating the pressure stability index and the overall function index of the well-functioning catheter. The reason why this parameter can be applied in different scenarios is that the internal average pressure is a key index whether in function evaluation, pressure stability analysis or adjustment effect evaluation, revealing the stability and reliability of the catheter during urine flow. Although the internal average pressure of the catheter is applied in both indexes, they correspond to different application scenarios respectively. The function index focuses on the overall performance of the catheter, and the pressure stability index focuses on the stability of the well-functioning catheter.

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

[0081] If the pressure stability index of a well-functioning catheter is not equal to the preset catheter pressure stability threshold, then this catheter is recorded as a catheter that needs pressure adjustment.

[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 adjustment is recorded as the first pressure-adjusted catheter. If the pressure stability index of a well-functioning catheter is greater than the preset catheter pressure stability threshold, the catheter requiring pressure adjustment is recorded as the second pressure-adjusted 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 to meet the current pressures in the bladder and urethra, resulting in abnormal urine drainage. 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, increasing the risk of damage to the urethra and bladder.

[0084] If the pressure stability index of a well-functioning catheter is equal to the 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, there is no need to perform any pressure adjustment operation on this well-functioning catheter, and its current pressure state is maintained.

[0086] Specifically, the automatic adjustment of the pressure of each catheter requiring pressure adjustment is as follows:

[0087] Obtain the internal catheter pressure, simulated bladder pressure, and simulated urethral pressure corresponding to the first pressure-adjusted catheter at the current simulated usage time point. Perform a mean process on the simulated bladder pressure and the simulated urethral pressure, and then perform a difference process on the result and the internal catheter pressure. The finally obtained value is recorded as the catheter pressure value to be adjusted.

[0088] Activate the pressure reduction device for the first pressure-adjusted catheter, that is, the pressure reduction device releases the catheter pressure value to be adjusted, and obtain and analyze the pressure data of the area where the first pressure-adjusted catheter is located, specifically including the simulated bladder pressure and the simulated urethral pressure corresponding to the first pressure-adjusted catheter at the simulated adjustment completion time point, and obtain the internal catheter pressure corresponding to the first pressure-adjusted catheter at the simulated adjustment completion time point. Comprehensively analyze to obtain the pressure stability index corresponding to the first pressure-adjusted catheter at the simulated adjustment completion time point. If the pressure stability index corresponding to the first pressure-adjusted catheter at the simulated adjustment completion time point is equal to the preset catheter pressure stability threshold, stop increasing the pressure. If the pressure stability index corresponding to the first pressure-adjusted catheter at the simulated adjustment completion time point is not equal to the preset catheter pressure stability threshold, perform pressure adjustment again according to the above pressure automatic adjustment process.

[0089] For the second adjustable pressure catheter, the pressure boosting device is activated, that is, the pressure boosting device increases the pressure value to be adjusted by the catheter, and obtains and analyzes the pressure data of the area where the second adjustable pressure catheter is located, specifically including the simulated bladder pressure and the simulated urethral pressure corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point, obtains the internal pressure of the catheter corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point, and comprehensively analyzes to obtain the pressure stability index corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point. If the pressure stability index corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point is equal to the preset catheter pressure stability threshold, the pressure release is stopped. If the pressure stability index corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point is not equal to the preset catheter pressure stability threshold, the pressure adjustment is carried out again according to the above pressure automatic adjustment process.

[0090] In this embodiment, the above-mentioned well-functioning catheter includes the first adjustable pressure catheter and the second adjustable pressure catheter. Therefore, the methods for obtaining the simulated bladder pressure, the simulated urethral pressure, and the internal pressure of the catheter corresponding to the first adjustable pressure catheter at the simulated adjustment completion time point, and the simulated bladder pressure, the simulated urethral pressure, and the internal pressure of the catheter corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point are the same as those for obtaining the simulated bladder pressure, the simulated urethral pressure, and the internal pressure of the catheter corresponding to the above-mentioned well-functioning catheters at the current simulated use time point; the analysis methods for the pressure stability index of the first adjustable pressure catheter during the current pressure adjustment cycle and the pressure stability index of the second adjustable pressure catheter during the current pressure adjustment cycle are the same as those for the pressure stability index of the above-mentioned well-functioning catheters.

[0091] It should be noted that when the pressure stability index of the first adjustable pressure catheter during the current pressure adjustment cycle is equal to the preset catheter pressure stability threshold, it means that by increasing the internal pressure of the first adjustable pressure catheter, the pressure corresponding to the first adjustable pressure catheter at the simulated adjustment completion time point is within a safe and stable range. Therefore, there is no need to perform a pressure increase adjustment operation on the pressure corresponding to the first adjustable pressure catheter at the simulated adjustment completion time point, and its current pressure state is maintained; when the pressure stability index of the second adjustable pressure catheter during the current pressure adjustment cycle is equal to the preset catheter pressure stability threshold, it means that by releasing the internal pressure of the second adjustable pressure catheter, the pressure corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point is within a safe and stable range. Therefore, there is no need to perform a release adjustment operation on the pressure corresponding to the second adjustable pressure catheter at the simulated adjustment completion time point, and its current pressure state is maintained, where the simulated adjustment completion time point is the next time point for pressure adjustment of the above-mentioned current simulated use time point.

[0092] Further, the adjustment data of each pressure-adjusting catheter during the pressure adjustment period specifically includes the pressure adjustment speed, the average urine discharge volume, and the pressure adjustment duration of each pressure-adjusting catheter during the pressure adjustment period.

[0093] It should be noted that the pressure adjustment speed of each pressure-adjusting catheter during the pressure adjustment period is obtained by a pressure sensor to real-time monitor the pressure change of the catheter during the pressure adjustment period, recording the change amount of each adjusted pressure, and performing a ratio process on the change amount of each adjusted pressure and the duration of each pressure adjustment to obtain the pressure adjustment speed. The average urine discharge volume is obtained by collecting the discharged urine with a urine collection container and using an accurate timing device to record the time, and dividing the total amount of collected urine by the recorded time period. The pressure adjustment duration is obtained by recording the time difference from the start to the end of the adjustment process with a timer. The pressure adjustment period refers to the time period required for the entire process from the start of the catheter pressure adjustment to the end of the catheter pressure adjustment. In this embodiment, it is arranged according to the actual pressure of each catheter. The pressure adjustment period includes, but is not limited to, the above current simulation usage time point and the simulation adjustment completion time point.

[0094] Specifically, the specific analysis process of the pressure adjustment stability index of each pressure-adjusting catheter is as follows:

[0095] Obtain the catheter function index of each pressure-adjusting catheter.

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

[0097] Compare the pressure adjustment duration of each pressure-adjusting catheter during the pressure adjustment period with the corresponding duration of the pressure adjustment period to obtain the pressure adjustment time ratio of each pressure-adjusting catheter during the pressure adjustment period.

[0098] It should be noted that the pressure regulation duration of each of the above-mentioned pressure-regulated catheters during the pressure regulation cycle refers to the time period during which the catheter actually performs pressure regulation within the pressure regulation cycle, while the duration corresponding to the pressure regulation cycle refers to the time 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 duration with the pressure regulation cycle duration, the performance of the catheter in terms of pressure regulation can be evaluated.

[0099] Comprehensively analyze the catheter function index of each pressure-regulated catheter, the pressure regulation time ratio, pressure regulation speed, and average urine output of each pressure-regulated catheter during the pressure regulation cycle to obtain the pressure regulation stability index of each pressure-regulated catheter.

[0100] In this embodiment, there are complex data change relationships among the catheter function index of each of the above-mentioned pressure-regulated catheters, the pressure regulation time ratio, pressure regulation speed, and average urine output of each pressure-regulated catheter during the pressure regulation cycle. A catheter with a high function index often has better pressure regulation ability, so it 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, thus having a higher pressure regulation time ratio and a faster pressure regulation speed. A catheter that can stably regulate pressure helps to urinate better, thus having a higher average urine output.

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

[0102]

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

[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 its corresponding relationship can be a pre-set mapping relationship. For example, a mapping set is formed based on 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 therein can be one-to-one or many-to-one, and in this example, its value range is [0, 1].

[0105] jc n is the pressure adjustment speed of the nth catheter requiring pressure adjustment within the pressure adjustment period, which indicates the speed at which the catheter adjusts the pressure within the urethra.

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

[0107] ts n is the pressure adjustment time ratio of the nth catheter requiring pressure adjustment within the pressure adjustment period, which refers to the ratio of the pressure adjustment duration to the corresponding duration of the pressure adjustment period.

[0108] Δts is the reference pressure adjustment time ratio preset in the pressure adjustment database, which refers to a reference value of the pressure adjustment time ratio preset in the pressure adjustment database.

[0109] pn n is the average urine output of the nth catheter requiring pressure adjustment within the pressure adjustment period, which refers to the average amount of urine discharged within the pressure adjustment period.

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

[0111] In this embodiment, when the catheter function index corresponding to the catheter requiring pressure adjustment within the pressure adjustment period is low, it means that the pressure adjustment efficiency of the catheter is not high, which will lead to a decrease in the urine discharge efficiency, and further affect the pressure adjustment stability index of each catheter requiring pressure adjustment. When the actual pressure adjustment time ratio is lower than the preset reference time ratio, it means that the catheter does not perform effective pressure adjustment for most of the time within the pressure adjustment period, which may cause large fluctuations in the pressure within the urethra and a decrease in stability; when the deviation degree between the pressure adjustment speed and the preset reference pressure adjustment speed is large, it will affect the precise control of the pressure within the urethra by the catheter, thus reducing the adjustment accuracy. When the average urine output is much lower than the reference value, it will cause too much urine to accumulate within the urethra, increasing the pressure within the urethra. Therefore, by analyzing in detail each parameter in the pressure adjustment stability index of each catheter requiring pressure adjustment, potential safety hazards that may exist during the use of the catheter can be discovered in a timely manner, which helps to avoid problems such as damage, leakage, or reflux of the catheter caused by improper pressure, thereby improving the safety of catheter use.

[0112] Furthermore, the pressure adjustment stability index of each catheter requiring pressure adjustment is compared with the threshold value of the catheter pressure adjustment stability index preset in the pressure adjustment database, and finally a warning prompt for the pressure adjustment of each catheter requiring pressure adjustment is given. The specific comparison process is as follows:

[0113] Compare the pressure adjustment stability index of each catheter requiring pressure adjustment with the threshold of the catheter pressure adjustment stability index preset in the pressure adjustment database. If the pressure adjustment stability index of a catheter requiring pressure adjustment is greater than or equal to the preset threshold of the catheter pressure adjustment stability index, there is no need to give a warning prompt for the pressure adjustment of this catheter requiring pressure adjustment.

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

[0115] If the pressure adjustment stability index of a catheter requiring pressure adjustment is less than the preset threshold of the catheter pressure adjustment stability index, mark this catheter requiring pressure adjustment as a catheter with pressure adjustment warning, and finally, a warning prompt for the pressure adjustment of this catheter with pressure adjustment warning needs to be given.

[0116] It should be noted that when the pressure adjustment index of a catheter is less than the preset threshold of the catheter pressure adjustment stability index, it means that the catheter requiring pressure adjustment through pressure adjustment has not reached the preset safety standards, and there may be risks of overpressure or underpressure. This catheter requiring pressure adjustment needs to be marked as a catheter with pressure adjustment warning and a warning prompt needs to be given for it. In this embodiment, the warning prompt is specifically: there is a risk of overpressure or underpressure in the catheter pressure adjusted automatically, and it is necessary to immediately reinspect the pressure reducing device or pressure increasing device of the catheter with pressure adjustment warning.

Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods to replace them. As long as they do not deviate from the structure of the invention or exceed the scope defined in this specification, they should fall within the protection scope of the present invention.
