Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the field of urological nursing, and particularly relates to a bladder irrigation device based on pressure and flow monitoring and automatic blockage removal function. BACKGROUND
[0002] Bladder irrigation is a common and important nursing measure in urological treatment, especially after bladder surgery, after urinary catheterization, and during the treatment of urinary tract infection. Bladder irrigation helps to remove blood clots, stones, impurities and infection sources in the bladder, prevent urinary tract infection, maintain urinary tract patency, and promote patient recovery. With the development of medical technology, traditional bladder irrigation methods have gradually exposed a series of shortcomings, especially in terms of urinary catheter blockage, pressure control, and irrigation fluid adjustment, which seriously affect the treatment effect and patient comfort, and may even cause serious complications. How to solve these problems and improve the accuracy, safety and patient experience of bladder irrigation has become a major problem in urological nursing.
[0003] Shortcomings of existing bladder irrigation technology
[0004] (1) Strong dependence on manual operation. Traditional bladder irrigation methods are mostly manually operated by medical staff, which is simple but has many uncertainties. Due to differences in technical level and experience among different nursing staff, the flow rate, pressure and temperature during the irrigation process are often difficult to control accurately. Excessive irrigation pressure may cause bladder damage, and low flow rate may not effectively remove blood clots or impurities in the bladder, and may even increase the risk of urinary tract infection due to incomplete irrigation. In addition, due to the lack of real-time data feedback in manual operation, nursing staff often cannot timely detect problems that may occur during bladder irrigation, and cannot achieve precise intervention.
[0005] (2) Frequent urinary catheter blockage. Urinary catheter blockage is one of the common complications in bladder irrigation, especially in cases of viscous liquid or high blood clots. The risk of urinary catheter blockage increases. Traditional bladder irrigation methods cannot monitor the patency of the urinary catheter in real time, and blockage usually occurs without being timely detected, causing problems such as poor liquid drainage, increased bladder pressure, and even bladder damage or urinary tract infection. Even if blockage occurs, traditional methods lack effective solutions, and blockage removal often depends on manual intervention, such as replacing the urinary catheter, manual irrigation, etc., resulting in treatment delay and affecting patient recovery progress.
[0006] (3) Inaccurate flow and pressure control. The flow and pressure of the irrigation liquid have a significant impact on the treatment outcome during bladder irrigation. Traditional methods often fail to accurately regulate the flow and pressure of the irrigation liquid, especially during the irrigation process. Excessive flow or pressure can cause bladder expansion or damage to the urinary catheter, while insufficient flow can result in poor irrigation results, failing to effectively remove blood clots, stones, and other impurities from the bladder. In addition, manual adjustment of flow and pressure is prone to human error, affecting the effectiveness of treatment.
[0007] (4) Difficulty in controlling the temperature of the irrigation liquid. The temperature of the irrigation liquid has a significant impact on patient comfort and treatment outcome. Extremely cold liquid can irritate the bladder and cause discomfort, while extremely hot liquid can cause damage to the bladder tissue. However, traditional bladder irrigation devices often lack temperature control functions, and the temperature of the irrigation liquid often depends on manual judgment, making it difficult to achieve precise control, resulting in discomfort for patients during the irrigation process, and even causing local bladder damage.
[0008] (5) Lack of real-time data monitoring and feedback mechanism. Currently, many bladder irrigation devices still lack real-time monitoring and data feedback mechanisms. Medical staff can only rely on their experience to judge the flow, pressure, and patency of the urinary catheter during the entire irrigation process. Moreover, once an abnormal situation occurs, such as blockage, excessive pressure, or poor liquid flow, traditional devices often cannot automatically detect and alarm, and often require manual observation or patient response to detect, thereby delaying treatment opportunities.
[0009] (6) Lack of automated and intelligent solutions. Traditional bladder irrigation devices are usually manually controlled and rely on manual operation and judgment, lacking automated and intelligent technical support. Especially in the case of handling urinary catheter blockage and other emergencies, traditional devices cannot detect and automatically unblock, often relying on nursing staff for manual intervention, which is not only time-consuming but also inefficient. Moreover, traditional devices often cannot be adjusted according to individual differences of patients, and the individualization and refinement of the treatment process are insufficient.
[0010] (7) Lack of remote monitoring and management functions. Existing bladder irrigation devices are usually operated locally and lack remote monitoring and management functions. Medical staff can only observe at the device, making it difficult to obtain real-time data of device operation and patients. Especially in a multi-patient, multi-bed environment, manual management becomes more difficult, and medical staff cannot real-time monitor patient treatment progress, lacking the ability to remotely adjust and intervene, which may result in some emergency situations not being handled in a timely manner.
[0011] Based on the limitations of traditional bladder irrigation methods, automated bladder irrigation devices have gradually become the focus of research and development. The bladder irrigation device based on pressure, flow monitoring and automatic unblocking function not only can monitor the pressure, flow and liquid flow in real time, but also can automatically detect and remove the blockage of the urinary catheter, adjust the flow and temperature of the irrigation fluid, and ensure the accuracy and safety of the treatment process. In addition, through the integration of algorithms and remote monitoring functions, the bladder irrigation device can realize real-time feedback of the device state, help medical staff adjust the treatment plan in time, and optimize the treatment effect.

[0050] The present application proposes a bladder irrigation device based on pressure and flow monitoring and automatic blockage removal function, aiming to solve the shortcomings of existing bladder irrigation technology by integrating modern sensing technology, control and automatic operation, and to improve the safety, accuracy and comfort of the bladder irrigation process. Compared with traditional bladder irrigation equipment, the present application has many advantages, can provide more efficient and accurate treatment during bladder irrigation, and significantly improve the quality of urological nursing.
[0051] 1. Improve the safety of the bladder irrigation process;
[0052] During the bladder irrigation process, the flow, pressure and temperature of the flushing liquid are crucial to the safety of the patient. Due to the limitations of manual control, traditional bladder irrigation devices often cannot guarantee the precise control of these parameters, which can easily lead to high pressure or low flow, resulting in bladder damage, urethral damage and other safety hazards. The present application integrates various sensors (such as pressure sensors, flow sensors and liquid flow monitoring sensors) to realize real-time monitoring of the irrigation process, which can accurately control the flow, pressure and temperature of the flushing liquid during the irrigation process.
[0053] Specifically, the pressure sensor monitors the pressure of the flushing liquid in real time to avoid damage to the bladder or urethra due to high pressure; the flow sensor accurately monitors the liquid flow to ensure the stability of the irrigation process; the liquid flow monitoring sensor monitors the speed and amount of liquid flow to ensure the patency of the urinary catheter and avoid urinary catheter blockage. Through real-time data feedback, the system can automatically adjust the flow and pressure of the flushing liquid to ensure the safety and stability of the irrigation process, greatly reducing the influence of human factors on treatment safety.
[0054] 2. Automated blockage detection and removal function to improve treatment effectiveness;
[0055] Ureteral obstruction is a common complication during bladder irrigation, especially when there are blood clots, stones or viscous substances in the liquid during the irrigation process. When obstruction occurs, the irrigation fluid cannot be properly discharged, the internal pressure of the bladder increases, and even serious complications such as bladder injury and urinary tract infection may occur. Traditional bladder irrigation methods usually rely on manual judgment and handling of blockage, which has the risk of delayed detection and handling of blockage, affecting treatment effectiveness.
[0056] The present application integrates a blockage detection sub-module, uses the data of pressure sensors and flow sensors to automatically judge whether the ureter is blocked. When the system detects a sudden decrease in flow or a sudden increase in pressure, the alarm system is triggered and the blockage removal device is started, automatically performing reverse flushing or pulse flushing operations to effectively remove the blockage and restore the patency of the ureter. This automated function avoids the risk of delay caused by manual intervention and can handle the blockage at the first time, thereby reducing the risk caused by blockage.
[0057] In addition, the present application also includes a cleaning and maintenance sub-module that can automatically restore the cleanliness of the pipeline after blockage removal to prevent secondary blockage or infection caused by unclean pipelines. This integrated blockage removal and cleaning function greatly improves the continuity and stability of the bladder irrigation process, ensuring the maximization of treatment effectiveness.
[0058] 3. Provide personalized treatment plans to improve patient comfort;
[0059] Each patient's bladder state and urinary tract condition is different, so the treatment plan for bladder irrigation should have individualized adjustment space. Traditional bladder irrigation devices usually rely on the manual experience of medical personnel for operation and cannot automatically adjust the flow, pressure and temperature of the irrigation fluid according to the individual differences of patients. This not only may affect the treatment effectiveness, but also easily makes patients feel uncomfortable.
[0060] The irrigation fluid control module of the present application adjusts the flow, pressure and temperature of the irrigation fluid through algorithms to meet the needs of different patients. The combination of liquid pumps and control valves can provide continuous, intermittent or pulse irrigation modes according to the set parameters, thereby meeting the treatment needs under different conditions. At the same time, the temperature control sub-module ensures that the temperature of the irrigation fluid is appropriate to avoid low-temperature liquid stimulating the bladder and causing discomfort.
[0061] This precise individualized adjustment not only improves the treatment effectiveness of the bladder irrigation process, but also greatly improves the comfort of patients, reducing the discomfort caused by too low or too high temperature during the irrigation process, and effectively avoiding pain caused by too high pressure or too large flow.
[0062] 4. Realize remote monitoring and management, improve treatment quality and efficiency;
[0063] In modern medicine, remote medical treatment and remote monitoring have become an important means to improve medical quality and work efficiency. Especially in the environment of multiple beds and multiple patients, real-time monitoring of the treatment process of patients is of great significance to improve nursing efficiency and reduce medical risks. Traditional bladder irrigation devices lack remote monitoring function, and medical staff need to rely on on-site observation, which cannot obtain real-time data of patients in time, and there is a problem of treatment management lag.
[0064] The control and data analysis module of the present application realizes the display and uploading of real-time data by connecting the display screen and the remote monitoring platform. Medical staff can check the device status and patient data through APP or cloud platform, real-time monitor the pressure, flow and liquid discharge during the irrigation process, timely adjust the treatment plan, and ensure the accuracy and effectiveness of the treatment. Remote monitoring function not only helps the centralized management of multiple patients, but also reduces the workload of medical staff, making the treatment process more efficient and convenient.
[0065] In addition, the remote platform also supports real-time push of alarm information. Once an abnormal situation occurs (such as blockage, excessive pressure, etc.), the system will automatically trigger an alarm and upload it to the remote platform, ensuring that medical staff can respond in the first time, thereby avoiding the risks caused by delayed response.
[0066] 5. Improve the level of automation and automation of device operation;
[0067] Traditional bladder irrigation devices usually rely on manual operation, and medical staff need to manually adjust the flow, pressure and temperature, and cannot real-time perceive the pipeline state and liquid flow condition, increasing the risk of human error. The present application can realize whole-process monitoring, real-time regulation and automatic feedback on the basis of automation through the sensor and control module. The real-time data monitored by the sensor is analyzed by the processor to real-time adjust the flow, pressure and temperature of the irrigation fluid, and to determine whether the blockage removal mechanism needs to be started according to the blockage detection algorithm.
[0068] This kind of automatic and automatic control method not only reduces the operation burden of medical staff, but also significantly improves the safety and accuracy of the treatment process, ensuring the efficiency and accuracy of bladder irrigation treatment. At the same time, the high degree of automation of the device also improves the controllability and convenience of operation in each link of the treatment process, greatly improving the work efficiency of medical staff.
[0069] 6. Promote the optimal use of medical resources;
[0070] With the aging population and the increasing number of chronic disease patients, the demand for urological treatment is increasing year by year, especially in the patient group who needs long-term bladder irrigation treatment. The traditional bladder irrigation device has many limitations, which leads to an excessive workload for medical staff and makes it difficult to provide adequate nursing support. Through the bladder irrigation device of the present application, the need for manual operation can be reduced, and an automated and intelligent treatment plan can be provided, thereby optimizing the utilization of medical resources.
[0071] Remote monitoring and data analysis functions enable medical staff to more efficiently manage multiple patients, adjust treatment plans in a timely manner, reduce patient waiting time, and improve the quality of care. In addition, the integration of automatic blockage removal and irrigation fluid adjustment functions enables the device to work continuously without frequent intervention, thereby improving the work efficiency of medical facilities and the treatment experience of patients.
[0072] 7. Improve patient treatment satisfaction;
[0073] Patient treatment satisfaction is one of the important indicators for evaluating medical quality, especially in the process of bladder irrigation and other long-term care, the comfort and treatment effect of patients directly affect their satisfaction with treatment. The present application greatly improves the comfort and treatment effect of patients during treatment by adjusting, automatic blockage removal and personalized treatment plan design, reducing discomfort and pain.
[0074] Patients no longer need to bear excessive or low irrigation pressure, and low or high temperature liquid stimulation is no longer a problem. Through remote monitoring and real-time data feedback, patients can receive more accurate and personalized treatment plans, the treatment process is more stable, and the treatment effect is more guaranteed, thereby improving the overall treatment satisfaction of patients.
[0075] In summary, the present application integrates sensors, algorithms, automated control and remote monitoring platforms to solve many problems in traditional bladder irrigation devices, providing a safer, more accurate and convenient bladder irrigation solution. It has significant advantages in improving treatment effect, patient comfort, medical resource utilization, etc., and can provide efficient, safe and personalized treatment support for urological care. BRIEF DESCRIPTION OF DRAWINGS
[0076] Figure 1 is a schematic diagram of the overall structure of the present application. DETAILED DESCRIPTION
[0077] The application will be described in detail below in conjunction with specific embodiments. With the continuous development of urological treatment, bladder irrigation as a key nursing measure plays a crucial role in the process of bladder surgery, urinary tube intubation, and urinary tract infection treatment. Bladder irrigation helps to remove blood clots, stones, impurities, and infection sources in the bladder, prevent urinary tract infection, and maintain the patency of the urethra. However, the existing bladder irrigation devices still have problems such as complex operation, difficulty in precise control of the irrigation process, and inability to timely handle urinary tube blockage. Therefore, developing a bladder irrigation device with automation and intelligent functions is the key to improving treatment effectiveness and patient experience.
[0078] The present embodiment aims to demonstrate the working principle and application of a bladder irrigation device based on pressure and flow monitoring and automatic blockage removal function. Through precise flow and pressure control, blockage detection and automatic blockage removal, temperature regulation, and remote monitoring, the automation and intelligence of the bladder irrigation process are realized, and the safety, effectiveness of treatment, and patient comfort are improved.
[0079] The bladder irrigation device of the present embodiment includes the following modules:
[0080] Sensor module: pressure sensor, flow sensor, and liquid flow monitoring sensor for real-time monitoring of the pressure, flow, and liquid discharge state of the irrigation fluid.
[0081] Automatic blockage removal module: including blockage detection sub-module, blockage removal device, and cleaning and maintenance sub-module for automatic detection of urinary tube blockage and removal of blockage through reverse flushing or pulse flushing.
[0082] Irrigation fluid regulation module: composed of irrigation fluid injection sub-module and temperature regulation sub-module for adjusting the flow, pressure, and temperature of the irrigation fluid.
[0083] Control and data analysis module: including processor and alarm sub-module responsible for receiving data and running blockage detection algorithm and triggering alarm in case of abnormal situation.
[0084] Specific operation process of the embodiment
[0085] 1. Preparation and system initialization;
[0086] Before starting bladder irrigation, the medical staff first checks whether each component of the bladder irrigation device is working properly. At this time, the operation panel of the device displays the working status of each module, including the sensor module, blockage removal device, temperature regulation system, etc. The medical staff needs to ensure that all sensors (pressure, flow, liquid flow monitoring, etc.) have been installed correctly and that the blockage removal device (such as reverse flushing pipeline) has been connected.
[0087] 2. Irrigation fluid injection and regulation;
[0088] According to the treatment plan, the appropriate irrigation fluid is selected and injected into the irrigation fluid injection module. The system regulates the flow and pressure of the irrigation fluid through the liquid pump and control valves, ensuring that it is within the set range. The control of liquid flow and pressure is automatically completed by the control module, avoiding the inaccuracy of manual intervention.
[0089] At the same time, the temperature regulation sub-module ensures that the temperature of the irrigation fluid is within the range of patient comfort (usually 36-37°C). Both overcooling and overheating of the liquid can cause irritation or damage to the bladder, so temperature regulation is crucial.
[0090] 3. Real-time monitoring and feedback;
[0091] During the bladder irrigation process, the sensor module will monitor the flow, pressure, and flow of the irrigation fluid in real time. The working principle of each sensor is as follows:
[0092] Pressure sensor: installed at the interface between the irrigation pipe and the urinary catheter, it monitors the pressure of the irrigation fluid in real time. If the irrigation pressure is too high, the system will automatically adjust the flow rate of the irrigation fluid to avoid damage to the bladder.
[0093] Flow sensor: installed in the irrigation fluid delivery path, it monitors the liquid flow to ensure the stability of the irrigation process. If the liquid flow is too small, it may result in poor irrigation effect, and the system will automatically increase the flow to the set value.
[0094] Liquid flow monitoring sensor: located at the outlet of the urinary catheter, it monitors the smooth discharge of the liquid in real time. If the liquid flow is slow or stagnant, the system will determine whether a blockage has occurred.
[0095] 4. Blockage detection and automatic unblocking;
[0096] Blockage is a common complication in bladder irrigation, especially when there are blood clots, stones, or viscous substances in the liquid, the urinary catheter is prone to blockage. In order to avoid the delay of treatment caused by blockage, the device adopts a blockage detection system.
[0097] Blockage detection sub-module: by analyzing the data of pressure and flow sensors, the system can monitor in real time whether there are signs of blockage in the urinary catheter. If the flow decreases sharply or the pressure increases suddenly, the system will determine that a blockage may have occurred and trigger an alarm.
[0098] Unblocking device: once the blockage is detected, the system will automatically start the reverse irrigation line for a short time of reverse flow operation to remove the blockage. In addition, the system can also choose pulse irrigation mode to clean the blockage in the urinary catheter through intermittent high-pressure pulses.
[0099] Cleaning and maintenance: after unblocking, the system will start the cleaning and maintenance sub-module to automatically clean the pipeline to prevent secondary blockage.
[0100] 5. Data logging and remote monitoring;
[0101] All data collected during the flushing process, including flow rate, pressure, and fluid volume, is recorded in real time and uploaded to a remote monitoring platform. Medical staff can view the equipment's operating status via an app or cloud platform and adjust parameters at any time to ensure the accuracy and safety of the treatment process.
[0102] For example, if the system detects a sudden slowdown in fluid flow in a patient, it will immediately issue an alarm via sound or light, notifying medical staff to take appropriate measures. The remote monitoring function also helps hospitals achieve centralized management of multiple patients, reducing the workload of on-site examinations for medical staff and improving work efficiency.
[0103] 6. Completion of treatment and follow-up care;
[0104] After bladder irrigation is completed, the system automatically determines whether the irrigation was sufficient based on the amount of fluid in the bladder and the extent of fluid drainage. If the fluid is not completely drained, the system will initiate an additional irrigation step to ensure the integrity of the treatment.
[0105] Meanwhile, the device continues to monitor the patency of the urinary catheter and uploads relevant data to a remote platform for medical staff to provide follow-up care. The system automatically records all key data throughout the treatment process, providing patients with a complete treatment record for subsequent medical analysis and patient management.
[0106] IV. Problems and Solutions During Implementation
[0107] During implementation, some practical challenges may be encountered, such as sensor malfunctions and blockage device failures. To address these, we have developed several backup plans:
[0108] Sensor failure: When a sensor fails, the system will automatically switch to the backup sensor and prompt the user to check the faulty sensor via the display screen.
[0109] Unclogging Failure: If backflushing or pulse flushing fails to effectively remove the blockage, the system will initiate a secondary unclogging scheme, including deep cleaning via electrically controlled valves and higher-pressure flushing fluid.
[0110] Through the description of this embodiment, we can see that the bladder irrigation device based on pressure and flow monitoring and automatic unblocking functions solves the shortcomings of traditional bladder irrigation methods in several aspects. The automated design improves the safety and accuracy of treatment, and the real-time monitoring and feedback functions ensure patient comfort and treatment effectiveness.
[0111] This invention provides a novel solution for bladder irrigation therapy by integrating multiple sensing technologies, control modules, and remote monitoring functions. It optimizes the use of medical resources, improves the work efficiency of nursing staff, and ensures the efficiency and personalization of the treatment process.

6. A bladder irrigation device based on pressure and flow monitoring and automatic unblocking function according to claim 3, characterized in that, The blocking algorithm includes the following steps: S1. Data Acquisition: Acquire real-time data from the flow sensor and pressure sensor; S2, Blockage Detection Logic: A sudden drop in flow: If the flow suddenly decreases and does not enter an intermittent or pulsatile mode, this may indicate a blockage in the urinary catheter. A sharp increase in pressure: If the pressure rises significantly (greater than the preset threshold), it indicates that the flow of the flushing fluid is obstructed, and there may be a blockage. Judgment criteria: The system considers both flow rate changes and pressure fluctuations to determine if a blockage has occurred. A blockage is considered to have occurred if the flow rate decreases by more than 50% and the pressure increases by more than 20% within the same time period. S3, Alarm and Blockage Relief Activation: Once a blockage is detected, the alarm system will trigger an audible or visual warning and upload the alarm information to the remote monitoring platform; the system will automatically activate the blockage removal device, including reverse flushing or pulse flushing.
7. The method of using the bladder irrigation device based on pressure and flow monitoring and automatic unblocking function according to claims 1-6 includes: S1. Preparation: Check that the bladder irrigation device and its modules are working properly, and ensure that all sensors (pressure, flow, fluid flow monitoring) and unblocking devices (reverse irrigation, pulse irrigation) are correctly installed; prepare an appropriate irrigation solution according to the doctor's order, ensure that the fluid temperature is suitable, and inject it into the irrigation solution injection module; S2. Start bladder irrigation. Activate the irrigation fluid injection submodule to inject irrigation fluid into the bladder via a liquid pump and control valve. At this time, the control and data analysis module adjusts the flow rate and temperature of the irrigation fluid according to set parameters (such as flow rate, pressure, and temperature) to ensure a comfortable and effective irrigation process. Each sensor module (pressure, flow rate, and fluid flow monitoring) begins to monitor the pressure, flow rate, and fluid discharge status in real time during bladder irrigation to ensure the stability of the irrigation fluid flow and the safety of the bladder. S3. Blockage detection, monitoring the patency of the urinary catheter: Pressure and flow sensors continuously monitor the flow and pressure of the flushing fluid, and the fluid flow monitoring sensor checks whether the urinary catheter is unobstructed. The system will automatically determine whether there is a risk of blockage. If the flow rate suddenly drops by more than 50% or the pressure rises significantly above the preset threshold, the system will activate the blockage detection submodule. If the system detects signs of congestion (a sharp drop in flow and an increase in pressure), it will trigger an alarm mechanism. S4. Alarm and blockage relief; When the alarm submodule is triggered, the system will issue an alarm via sound or light signals when an abnormality is detected, based on the blockage detection logic, to notify medical staff to handle the situation promptly. Once the blockage is confirmed, the system automatically activates the blockage removal device: by controlling the valves and the reverse flushing pipeline, flushing fluid is injected into the urinary catheter in a short-term reverse flow to help clear the blockage; the system can also select a pulse flushing mode, which uses intermittent high-pressure pulses to clear the blockage in the urinary catheter. S5. Pipeline Cleaning and Restoration, Cleaning and Maintenance: After unblocking, the system will activate the cleaning and maintenance submodule to ensure that the flushing device is restored to a clean state through automatic pipeline cleaning, preventing recurrence of blockage; the cleaned equipment will continue to monitor the flow and pressure of the flushing fluid to ensure stable operation of the system; S6. End irrigation: Based on the amount of fluid in the bladder and the fluid discharge, the bladder irrigation process is completed; Data recording and uploading: The system records and uploads the data (such as pressure, flow rate, fluid volume, etc.) throughout the irrigation process to the remote monitoring platform, providing medical staff with a complete treatment record; S7. Follow-up care and monitoring: Medical staff can monitor the patient's treatment status, view data, and adjust parameters as needed through the cloud. After bladder irrigation, the system can continue to monitor the patency of the urinary catheter and provide follow-up care, such as regularly checking the status of the urinary catheter and monitoring bladder function.
