Description

Technical Field

[0001] The present invention relates to the technical field of medical care, and in particular to an intelligent urination care system and an intelligent urination care method. Background Art

[0002] With the increasing aging of the population, the number of disabled people continues to increase. Due to the loss of physical functions, disabled people are unable to independently complete basic activities in daily life, such as urination and defecation, and require long-term nursing and care. Traditional nursing methods mainly rely on manpower, which is not only labor-intensive and inefficient, but also fails to protect the privacy of the disabled, makes it difficult to meet the needs of the disabled, and also places a heavy burden on caregivers and families. In the field of medical care equipment technology, care products for the disabled have made certain progress. Existing nursing equipment usually has basic flushing, drying or sterilization functions, and some products also try to integrate multiple functions to improve nursing efficiency. These devices have alleviated the nursing difficulties of disabled people to a certain extent and provided auxiliary tools for caregivers.

[0003] However, existing technologies still have many shortcomings. Existing care products have significant flaws in sensing technology, often using single sensors (such as humidity or temperature sensors) to determine defecation, resulting in false alarm rates exceeding 30%. Single sensors are susceptible to interference from environmental factors. For example, humidity sensors can misjudge in humid environments, while temperature sensors can fail when exposed to temperature fluctuations, making it impossible to accurately and reliably identify defecation events. This not only increases the workload of caregivers but can also lead to delayed care, compromising the comfort and health of disabled individuals. Summary of the Invention

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. It should be noted that, in the absence of conflict, the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0022] With the increasing aging of the population, the number of disabled people continues to increase. Due to the loss of physical functions, disabled people are unable to independently complete basic activities in daily life, such as urination and defecation, and require long-term nursing and care. Traditional nursing methods mainly rely on manpower, which is not only labor-intensive and inefficient, but also fails to protect the privacy of the disabled, making it difficult to meet the needs of the disabled, and also brings a heavy burden to caregivers and families. Therefore, there is an urgent need for an intelligent nursing system and method that can meet the needs of the disabled, improve nursing efficiency, protect user privacy, and reduce the burden on caregivers. Although there are many nursing products on the market, there is still a technical gap in nursing that integrates flushing, sterilization, drying, and odor extraction functions.

[0023] To solve the above problems, the embodiments of the present application provide an intelligent urine care system and method. They have the following functions: intelligent sensing of urine discharge, automatic flushing, automatic sterilization with medicated washing, automatic drying, odor extraction, and the ability to simultaneously use the system while inserting a urinary catheter, protecting the user's privacy while reducing the workload of caregivers. like Figure 1As shown, the embodiment of the present application provides an intelligent urine collection care system, including a urinal 1, on which an intelligent recognition system 4 and a control unit are provided. The urinal 1 has a collection chamber 2 therein, which is used to collect urine. The urinal 1 is provided with a collection port 15 and an external discharge hole 3 connected to the collection chamber 2. The collection port 15 is used to allow urine to flow in, and the external discharge hole 3 is used to discharge urine; the intelligent recognition system 4 includes a plurality of excretion detectors and a plurality of environmental detectors arranged in the collection chamber 2, the excretion detectors are used to detect urine excretion, and the environmental detectors are used to detect the environment of the collection chamber 2; the urinal 1 is provided with a plurality of connecting ports connected to the collection chamber 2, the edges of the connecting ports extending outward into a tubular shape, and the connecting ports are used to connect different care systems respectively, so as to care for the collection chamber 2 through the connecting ports; the excretion detector, the environmental detector and the care system are respectively connected to the control unit, and the control unit is used to control the start or shut down of the care system.

[0024] The embodiment of the present application significantly improves the accuracy of excretion event recognition and reduces the false alarm rate through multi-sensor collaborative detection; modular expansion design: the connecting port supports quick connection to different care systems (flushing / sterilization / drying, etc.) to achieve customizable functions; fully automatic closed-loop control: the control unit automatically triggers the care process, reducing manual intervention and improving care efficiency and timeliness.

[0025] By incorporating multiple sensors into the intelligent recognition system and control unit, the system can detect defecation and provide care in a timely manner, effectively resolving the high false alarm rate associated with single sensors in existing technologies. This improves the accuracy and stability of defecation detection, reduces the workload of caregivers, and enhances the comfort and health of disabled individuals. It can be used in conjunction with nursing equipment (such as mattresses) to meet the needs of disabled individuals with bowel movements during prolonged bed rest.

[0026] like Figure 1 The urinal 1 of the present application is shown. The edge of the collection port 15 is provided with several wearing and fixing holes 9. The outer surface of the urinal 1 is provided with several protruding fixing blocks, each of which is provided with a tethering hole 10. The tethering hole 10 and the wearing and fixing hole 9 are used to pass through fixing parts to fix the urinal 1. The urinal 1 can be conveniently fixed to a disabled person or to a nursing device using fixing parts (such as an elastic band). This ensures that the urinal 1 is stable and reliable during use, is not easily displaced or detached, and prevents leakage caused by displacement. This improves the safety of use, and also facilitates the wearing operation of the caregiver, saving nursing time. It is also adaptable to different equipment and user body shapes: the multi-hole design supports flexible binding and improves wearing comfort.

[0027] The urinal 1 comprises a sealed upper shell 11 and a lower shell 12. Several pairs of protruding connection blocks are positioned near the joint on the outer surfaces of the upper and lower shells 11 and 12. Each of these blocks is provided with a coaxial pin hole 13, through which a pin passes to connect the upper and lower shells 11 and 12. This sealed connection of the upper and lower shells 11 and 12, secured by the connection blocks and pins, makes the urinal 1 easier and faster to assemble and disassemble, facilitating cleaning, maintenance, or component replacement when necessary. It also ensures the sealing of the collection chamber 2, preventing urine leakage and odor, and ensuring that no fluid leaks from the collection chamber, thereby enhancing the product's practicality and reliability.

[0028] The urinal 1 is provided with a catheter port 14 that connects to the collection chamber 2. The inner diameter of the port is adapted to the standard catheter size (Fr12-Fr18), and a backflow prevention check valve is installed at the port. The catheter port 14 is used to pass the catheter through. The catheter port 14 is located at the connection between the upper shell 11 and the lower shell 12; the catheter port 14 is located near the external discharge hole 3; the edges of the catheter port 14 extend inward and outward in a tubular shape. It is convenient for the insertion of the catheter and is located at the connection between the upper shell 11 and the lower shell 12, near the external discharge hole 3. Figure 2 and Figure 4 As shown, both sides of the urinal 1 are provided with pin connections. When using the urinal 1 with a catheter inserted, the user first separates the upper shell 11 and the lower shell 12 on one side, and then rotates the other side through the pin to connect. The catheter interface 14 is divided into two halves along the side wall, so that the catheter is placed into the catheter interface 14, and then the other sides of the upper shell 11 and the lower shell 12 are combined and fixed by pins. The catheter interface 14 combines and fixes the catheter. It can be used even if the user has inserted a catheter, realizing undisturbed care for patients with catheters. There is no need to remove the catheter when using this urinal 1. The catheter interface 14 supports the use of catheter equipment by severely disabled people, realizing diversified functions, and is unisex and does not need to be customized for each user. At the same time, the edge of the catheter interface 14 extends inwardly and outwardly into a tubular shape, which is conducive to the smooth insertion and fixation of the catheter, and supports the catheter to prevent the catheter from being offset or twisted during use. The external discharge hole 3 is set at the bottom of the lower shell 12, which facilitates the natural discharge of urine under the action of gravity and avoids urine retention; the connecting port is set at the top of the upper shell 11, which is conducive to the function of each nursing system. For example, the exhaust ventilation system can effectively discharge the odorous gas in the collection chamber 2, and the drying system can quickly dry the inside of the collection chamber 2. Such a layout design is more in line with fluid mechanics and actual use, and improves the nursing effect and efficiency of the entire system.

[0029] The collection chamber 2 is configured to be funnel-shaped, extending from the external discharge hole 3 toward the collection port 15 with an increasing width. A silicone pad 16 is provided at the end of the collection port 15. The shape of the silicone pad 16 is a curved surface that fits the curvature of the human body to avoid compressing the skin. It is suitable for long-term wear and reduces side leakage. It can improve the user's comfort, reduce friction and discomfort, and make the urinal more ergonomic during use, facilitate urination for disabled people, and enhance the user experience of the product. The wearing fixing hole 9 is provided on the silicone pad 16. The urinal 1 adopts a surface high molecular polymer material, combined with a local silicone pad 16 to ensure that splashing liquid does not leak out during cleaning. The silicone pad 16 adopts a bionic 3D curved surface design and is provided with an antibacterial coating on the surface. The hardness of the surface in contact with the human body is Shore A20-30‌.

[0030] Several connecting ports include suction port 5, hot air port 6, drug washing port 7 and cleaning port 8. The nursing system includes: The exhaust ventilation system is connected to the suction port 5, which is used to purify the air in the collection chamber 2 and exhaust odors. The control unit controls the start-up of the exhaust ventilation system, which includes a negative ion generator and an odor extraction module. The negative ion generator is responsible for ionizing and decomposing odorous gas molecules to achieve efficient odor removal. The odor extraction module consists of a centrifugal fan and an activated carbon filter component, which work together. Under standard atmospheric pressure, the ventilation efficiency is as high as 50 cubic meters per hour or more. The centrifugal fan provides power to ensure the rapid extraction and discharge of gas; the activated carbon filter component filters tiny particles and residual odors in the gas, doubly ensuring the cleanliness of the exhaust gas, removing odors, and changing the ambient air quality of the collection chamber 2. Figure 3 and Figure 5 As shown, the suction vent 5 is connected to the exhaust ventilation system through the suction air connector 18. A water-proof and breathable pad 17 is also provided at the suction vent 5 to allow fresh air to enter the collection chamber 2. The gray part is the sensor installation position.

[0031] The drying system, connected to the hot air outlet 6, is used to dry the collection chamber 2. The drying system includes a temperature adaptive module and a wind speed adjustment module, which adjust the hot air parameters according to the ambient temperature to achieve local drying. The wind speed adjustment module of the drying system supports continuously variable speeds of 0.5-3m / s, and the temperature difference between the hot air and human skin temperature does not exceed ±2°C. The control unit activates the drying system. After the intelligent recognition system identifies the ambient and human temperatures, it automatically adjusts the hot air temperature to dry the cleaned area. By adjusting the wind speed and air volume, a slow-blowing method of hot air is set to improve the local environment and prevent eczema, erysipelas, dermatophytes, and skin infections.

[0032] The medicated disinfection system, connected to the medicated disinfection port 7, sterilizes the collection chamber 2. The system includes a drug concentration adjustment module, an atomization spray module, and an air curtain control module. These modules dynamically adjust drug concentration based on temperature changes and cover the target area through atomization spraying. The drug concentration adjustment module dynamically matches the dilution ratio of the hydrogen peroxide or hypochlorous acid solution based on temperature sensor data from the intelligent recognition system. The atomization module regulates the atomization frequency of the piezoelectric ceramic atomizer (1.7-2.4 MHz) to maintain a particle size range of 10-50 μm. The control unit activates the medicated disinfection system, adjusts the drug concentration through temperature sensor recognition, and determines the spraying area through intelligent recognition using optical and image sensors. The uniformity of the atomized drug is ensured by adjusting the drug liquid pressure and the wind force (air curtain) to disinfect the interior of the urinal.

[0033] The flushing system is connected to the cleaning port 8 and is used to flush the collection chamber 2 and / or the user's perineum. The urinal is equipped with a warm water flushing device, which can achieve a gentle flushing function for the perineum by electrically or manually controlling the temperature and the adjustment of the water outlet pressure. At the same time, the inside of the urinal is cleaned. The flushing system includes a warm water supply module, a pressure regulating module and a flushing nozzle, which are used to flush the user's perineum and the inner wall of the urinal; the warm water supply module of the flushing system has a built-in PID temperature control algorithm, and the water temperature adjustment range is ±0.5°C. The pressure regulating module supports a pulse flushing mode of 0.01-0.15MPa.

[0034] The embodiments of the present application reduce the risk of skin irritation and infection through a warm water flushing and drying system and an exhaust function.

[0035] The control unit includes: a database with a pre-set defecation behavior recognition model; a data receiving module that receives three-dimensional situational awareness data collected by the intelligent recognition system 4 in real time, cross-validating the multi-dimensional data to overcome the environmental interference of a single sensor and reduce the risk of misjudgment; a comparison module that retrieves the defecation behavior recognition model from the database based on the three-dimensional situational awareness data received by the data receiving module and compares it. It determines whether defecation has occurred by determining whether the three-dimensional situational awareness data exceeds the threshold set by the defecation behavior recognition model; and an instruction generation module that selects the corresponding nursing system control mode from the corresponding defecation behavior recognition model based on the comparison module's results, generates control instructions for the nursing system, and automatically matches the optimal nursing plan based on the comparison results to avoid invalid operations (such as mistakenly starting flushing when there is no defecation). The data collected by the intelligent recognition system is systematically processed and analyzed. By comparing it with the defecation behavior recognition model in the database, it accurately determines whether defecation has occurred and generates corresponding nursing system control instructions, further improving the accuracy of defecation identification and the timeliness of care.

[0036] The control unit is connected to a manual operator and a signal transmission device. The manual operator displays the control unit's operating status and controls the instruction generation module. The signal transmission device transmits signals to the user terminal, displaying the control unit's operating status and controlling the instruction generation module. It supports both local manual operation and remote terminal control to accommodate diverse care scenarios. The user terminal synchronously displays device status, enabling caregivers to respond promptly to anomalies. The signal transmission device enables remote monitoring via Bluetooth / Wi-Fi.

[0037] The control unit detects any subsystem failure and triggers: a. immediately stop the actuator; b. start the backup manual operation mode; c. send a remote alarm signal.

[0038] The control unit also includes a learning module, which uses the control instructions corresponding to the sets of three-dimensional situational awareness data received by the data receiving module to add a new defecation behavior recognition model to the database. This module uses the new defecation behavior recognition model to optimize the threshold set by the new defecation behavior recognition model and the corresponding control mode of the nursing system in the instruction generation module. The control instructions are continuously optimized through historical data to improve system adaptability (such as personalized nursing rhythm), learn the user's defecation patterns, and dynamically adjust sensor sensitivity and nursing strategies. The learning module can continuously optimize control instructions based on the three-dimensional situational awareness data and its corresponding control instructions received by the data receiving module multiple times. This allows the system to continuously improve nursing methods as the number of uses increases, improving the accuracy and adaptability of nursing care and better meeting the nursing needs of people with different disabilities.

[0039] The excretion detector includes: infrared counter-radiation sensor, millimeter wave radar, thermal sensor, humidity sensor, liquid level sensor and flow sensor; the environmental detector includes: odor sensor, ultrasonic sensor and pressure distribution sensor; the excretion detector and environmental detector generate three-dimensional situational awareness data and transmit it to the control unit, which determines urine excretion to control the care system.

[0040] The urinal's integrated optical recognition (infrared beam sensor), image recognition (millimeter-wave radar), temperature recognition (thermal sensor), humidity recognition (humidity sensor), odor recognition (odor sensor), acoustic recognition (ultrasonic sensor), liquid level recognition (humidity sensor, liquid level sensor), and flow recognition (flow sensor) provide three-dimensional on-site situational awareness, completing a closed loop of intelligent recognition. Core algorithms mitigate the possibility of missed and incorrect reports.

[0041] The image sensor in the intelligent recognition system is a low-light millimeter-wave radar, which works in conjunction with an infrared counter-radiation sensor to achieve excretion detection through morphological analysis and liquid level dual verification.

[0042] Millimeter-wave radar is used to detect changes in shape, with a range of 0-10cm and an accuracy of ±0.5mm; infrared counter-radiation sensors are used to detect the passage of liquids, with a range of 0-100ml / s and an accuracy of 5ms response; thermal sensors form a thermal array to detect temperature field distribution, with a range of 20-50℃ and an accuracy of ±0.2℃.

[0043] After testing, the excretion recognition accuracy of the embodiment of the present application was 95.3%, which was 26.7% higher than that of traditional equipment; a single care time was 60 seconds, which was 71.5% less than that of traditional equipment; the skin infection rate was 1.3 times / 1,000 days, which was 89.3% less than that of traditional equipment.

[0044] This embodiment of the application constructs a three-dimensional situational awareness network based on eight heterogeneous sensor types (optical, image, temperature, humidity, odor, acoustic, liquid level, and flow), and combines it with a machine learning algorithm to establish a defecation behavior recognition model. This effectively overcomes the technical bottleneck of high false alarm rates associated with traditional single sensors. The collaborative working mechanism of low-light millimeter-wave radar and infrared beam sensors enables dual verification of excrement morphology analysis and liquid level detection, significantly improving recognition accuracy compared to existing technologies.

[0045] The present invention has the following advantages: 1) A three-dimensional situational awareness network based on eight heterogeneous sensor types (optical, image, temperature, humidity, odor, acoustic, liquid level, and flow) was constructed. Combined with machine learning algorithms, this model was developed to identify defecation behavior, effectively overcoming the technical bottleneck of high false alarm rates associated with traditional single-sensor systems. The collaborative working mechanism of low-light millimeter-wave radar and infrared beam sensors enabled dual verification of excrement morphological analysis and liquid level detection, significantly improving recognition accuracy compared to existing technologies.

[0046] 2) Developed a multi-stage nursing process with temperature-pressure-concentration adaptation; a pulsed flushing system (35-42°C warm water, 0.01-0.15MPa adjustable pressure); a dynamic medicated wash system (the concentration of the chlorhexidine solution is 0.01% to 0.05%, adjusted in real time with temperature); and a gradient drying system (±2°C skin temperature difference control, 0.5-3m / s stepless wind speed). Through the coordinated optimization of the PID temperature control algorithm and atomized particle size control (10-50μm), the incidence of complications such as incontinence dermatitis was significantly reduced.

[0047] 3) The ergonomic 3D curved sealing structure (ShoreA20-30 hardness silicone pad + antibacterial coating) combined with centrifugal air curtain splash protection technology achieves a liquid sealing efficiency of >98%. The modular design is compatible with the catheter interface (Fr12-Fr18 anti-reflux valve) and can be quickly adapted to different nursing scenarios. The exhaust system uses a combination of negative ion generation and activated carbon filtration to purify the air, with an air exchange efficiency of 50m 3 / h or more.

[0048] This solution transcends the technical limitations of traditional nursing equipment, which typically have limited functionality. Through multi-system coordinated control (rinsing → medicated wash → drying → ventilation in less than 120 seconds) and remote monitoring (Bluetooth / Wi-Fi), it improves nursing efficiency and significantly reduces the risk of skin infections. This provides a new paradigm for intelligent nursing care for people with disabilities, combining privacy protection with personalized care. Experimental validation has shown that this device improves nursing efficiency and significantly reduces the incidence of skin complications, making it particularly suitable for bedridden patients with disabilities.

[0049] On the other hand, the embodiment of the present application further provides a urine collection intelligent care method for caring for the urine collection intelligent care system described above, comprising the following steps: Real-time detection of urine excretion through intelligent recognition system 4; Based on the urine excretion situation, when the preset excretion threshold is exceeded, the control unit is automatically triggered to control the flushing system, the medical washing and sterilization system, the drying system, and the extraction and ventilation system in sequence to perform nursing operations on the collection chamber 2 of the urinal 1 according to the set nursing sequence.

[0050] like Figure 6 The following is a workflow diagram of an intelligent urination care method provided in an embodiment of the present application: S1, intelligent recognition system 4 detects urine excretion; S2, the control unit controls the flushing system to start; S3, the control unit controls the flushing system to shut down and the drug washing and sterilization system to start; S4, the control unit controls the chemical washing and sterilization system to be turned off and the drying system to be started; S5, the control unit controls the drying system to shut down and the exhaust ventilation system to start; S6, the control unit controls the exhaust ventilation system to shut down.

[0051] The timing control logic of the embodiment of the present application is as follows: 0-15s: double verification of excretion events (morphology + liquid level); 16-45s: dual-zone pulse flushing (human body + toilet); 46-75s: dynamic drug washing (adaptive concentration adjustment); 76-105s: gradient drying (temperature / wind speed closed loop); 106-120s: Composite extraction (negative ion + activated carbon filtration).

[0052] This intelligent urination care method starts the flushing system, drug washing and sterilization system, drying system and extraction and ventilation system in a reasonable order. Through the coordinated operation of each system, it can comprehensively and effectively complete the cleaning and care process of the collection cavity and the user's perineum, ensuring timely removal of urine, sterilization and disinfection, drying and purification of the air after excretion, preventing problems such as skin infection caused by residual excrement, and improving the quality of life of disabled people. At the same time, it also provides nursing staff with a set of standardized and automated nursing processes, reducing the complexity and labor intensity of nursing work, and improving the level and efficiency of nursing services.

[0053] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
