Description

Technical Field

[0001] This invention relates to the field of bladder irrigation device technology, and more particularly to an intelligent integrated bladder irrigation device based on automatic RGB color recognition. Background Technology

[0002] A bladder irrigator is an important medical device, primarily used to clean and irrigate the bladder to prevent and treat urinary tract infections, bladder stones, bladder tumors, and other diseases. Its core function is to remove blood clots, mucus, and other foreign substances from the bladder, promoting patient recovery.

[0003] Chinese invention patent CN118490907A discloses an automatic bladder irrigation device, including a base. One end of the base has a water storage mechanism and a waste collection mechanism. An inner partition is fixed to the inner side of the other end of the base. Supports and a hollow cylinder are respectively arranged on both sides of the inner partition and inside the base. A Y-shaped three-way urinary catheter is arranged inside the upper end of the inner partition. A pressure sensor is arranged on the outer side of the Y-shaped three-way urinary catheter and above the inner partition. A control module and an ultrasonic module are respectively arranged inside the inner partition. A water pump is fixed to the upper end of the support. A support block is fixed to the inner side of the base and above the hollow cylinder, and a second drainage hose is arranged inside the support block. This invention provides an automatic bladder irrigation device that, through its overall structural design, achieves automated bladder irrigation, effectively improving irrigation efficiency compared to relying on gravity to allow irrigation fluid to flow out naturally or for medical personnel to manually squeeze the urinary catheter to drain the irrigation fluid.

[0004] Chinese invention patent CN114522289A discloses a bladder irrigation device. This device includes a cylindrical body and several ports connected to one end of the cylindrical body, the ports selectively communicating with the interior of the cylindrical body. The other ends of the ports are connected to several medical devices and / or the bladder and / or a catheter in a fluid-transmitting manner. One or more of the medical devices are equipped with the heating device. This bladder irrigation device simplifies the operation for medical personnel, saves irrigation time, improves irrigation efficiency, and achieves stable control over the entire irrigation process.

[0005] Chinese invention patent CN109224169B discloses a bladder irrigation device. In this device, one end of each of the two branches of the irrigation bag connecting tube is connected to one end of a three-lumen urinary catheter connecting tube. The other ends of each branch are connected to an irrigation bag. A first flow rate regulator is installed on each branch. The three-lumen urinary catheter connecting tube is connected to the irrigation drip tube of the three-lumen urinary catheter. One end of the drainage tube is connected to the urinary catheter drainage tube end of the three-lumen urinary catheter, and the other end is connected to a collector. A drainage tube squeezing device and a second flow rate regulator are installed on the drainage tube. This invention overcomes the shortcomings of existing bladder irrigation devices, such as inconvenient flow rate control, difficulty in measurement, and easy blockage of the urinary catheter tip, which leads to wasted manpower and time for nursing staff. Most existing bladder irrigation devices are mechanical, requiring manual observation of the irrigation fluid color and time to verify flow rate adjustment. This makes it difficult to achieve rapid and accurate control, thus reducing the therapeutic effect of bladder irrigation devices on patients. Summary of the Invention

[0006] To address the aforementioned problems in existing technologies, we now provide an intelligent integrated bladder irrigation device based on automatic RGB color recognition.

[0007] The specific technical solution is as follows: Design an intelligent integrated bladder irrigation device based on RGB color automatic recognition, including a medicine bag, a main pipe and a color recognition module. The bottom of the medicine bag is connected to one end of the inlet pipe, and the other end of the inlet pipe is connected to one end of the main pipe. The inlet pipe is connected to a clamp valve by a snap-fit ​​mechanism. An outlet pipe is provided below the inlet pipe and is connected to the main pipe. The bottom of the outlet pipe is connected to a storage bag, and the color recognition module is provided on the side of the outlet pipe.

[0008] Preferably, the color recognition module is connected to the liquid outlet tube via a fastener buckle, and the buckle is connected to the liquid outlet tube by a snap-fit ​​mechanism.

[0009] Preferably, the color recognition module integrates a color sensor, a light source, and a timer. The color recognition module uses optical principles to detect the color of the liquid, and a temperature sensor is integrated on the color recognition module.

[0010] Preferably, the color recognition module integrates a color sensor, a light source, and a timer. The color recognition module uses optical principles to detect the color of the liquid, and a temperature sensor is integrated on the color recognition module.

[0011] Preferably, the clamping valve is a proportional electric clamping valve, which adjusts the clamping force through voltage or current signals. The control unit performs color recognition based on a deep learning model and supports Wi-Fi and Bluetooth remote communication.

[0012] Preferably, it includes the following steps: S1: Acquires flushing fluid color data via an RGB sensor; S2: Classify and subdivide color data to generate control commands; S3: Adjust the clamping force of the clamp valve according to the control command to control the flow rate of the flushing fluid.

[0013] The above technical solution has the following advantages or beneficial effects: By incorporating a color recognition module and a control unit, when a patient needs to use the bladder irrigator, the color recognition module is clipped onto the outlet tube, and the clamp valve is installed on the inlet tube. When colorless liquid enters the orifice, the color recognition module calibrates. When the color of the flowing liquid changes, the control unit controls the clamp valve according to the color change via a pre-programmed sequence. The clamp valve controls the flow rate of the infusion tube, thus automatically adjusting the irrigation flow rate based on the irrigation color, eliminating the need for real-time monitoring by medical staff.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0020] Example 1 Reference Figure 1-3 A smart integrated bladder irrigation device based on RGB color automatic recognition includes a medicine bag 1, a main pipe 2 and a color recognition module 8. The bottom of the medicine bag 1 is connected to one end of the inlet pipe 3, and the other end of the inlet pipe 3 is connected to one end of the main pipe 2. The inlet pipe 3 is connected to the clamp valve 7 by a snap-fit. The outlet pipe 4 is provided below the inlet pipe 3. The outlet pipe 4 is connected to the main pipe 2. The bottom of the outlet pipe 4 is connected to the storage bag 5. The color recognition module 8 is provided on the side of the outlet pipe 4.

[0021] Specifically, the program design logic is divided into two steps. The first step is to establish a reliable color classification to distinguish between yellow and red, which is the key judgment for controlling the stop of the drip. The second step is to further subdivide the red color when red body fluid is detected. First, color calibration is performed when there is no liquid in the tubing or when it is filled with a bloodless transparent liquid such as saline. To facilitate the classification of the red series, the blood index is defined as BI = R / G + B*100, where 100 is the scaling factor. When body fluid flows through, the body fluid is first identified by its major color category, such as the basic colors red, green, and blue. Based on the color chart, the color threshold for distinguishing between color 1 (pale yellow) and color 2 (pale pink) is studied. The reason is that color 1 and color 2 are extremely important and are the key color numbers for controlling the start and stop of the titration. By normalizing the RGB colors, the influence of different light intensities is eliminated. Utilizing the characteristics of red (high R, low G, low B) and yellow (high R, high G, low B), the program first reads the RGB values ​​and calculates... The R / G value is used to distinguish between red and yellow. Color No. 1, i.e., yellow, is a mixture of red and green in a very balanced ratio, meaning that the rinsing liquid is pale yellow. When the color is yellow or similar to other yellow series, the R / B ratio is close to 1. The R / G value of color No. 2 is measured to be about 1.2. Subsequently, as the red gradually deepens, the R value remains high, greater than 200, while the G value drops significantly to below 100. Therefore, it is stipulated that an R / B ratio of 0.8-1.2 is considered to be similar to color No. 1, i.e., yellow series, and the equipment is in observation mode. When the ratio is greater than 1.2, it is judged to be red series, and subsequent red subdivision operations are started. When rinsing is required, the color change is linear, making it impossible to use precise RGB values ​​for comparison and classification. First, a custom classification is performed based on the user's RGB data of the color, and then a detection model is obtained through training. Then, deep learning is used to identify the current liquid color number, and different color numbers are controlled by the control unit 6 to send different control commands to the pinch valve 7. The RGB color sensor development part is completed on the development board. After the program is written, it is burned into the main control chip. It can also integrate Wi-Fi and Bluetooth connectivity, which can send RGB data and alarm information to a mobile APP, computer or hospital monitoring system in real time to achieve remote control.

[0022] Example 2 Furthermore, the color recognition module 8 is connected to the buckle 9 via fasteners, and the buckle 9 is connected to the liquid outlet tube 4 by snapping. The color recognition module 8 integrates a color sensor, a light source, and a timer. The color recognition module 8 uses optical principles to detect the color of the liquid, and a temperature sensor is integrated on the color recognition module 8.

[0023] Specifically, the image recognition system continuously monitors the color changes of the flushing fluid, ensuring uninterrupted operation day and night through a supplemental lighting device. It automatically identifies different clarity levels, such as color codes on color charts, and immediately triggers an alarm mechanism upon detecting anomalies. It can also integrate a flow monitoring device, achieving high-precision measurement through droplet counting analysis or dynamic volume recognition, with an error range controlled within 2%. Combined with an AI visual model, it identifies bleeding levels, such as a preset color threshold of 5 corresponding to active bleeding. The control unit 6 can automatically adjust the speed within 3 seconds, such as accelerating flushing to dilute blood / remove blood clots, or slowing down to protect fragile mucous membranes. Through the integration of a high-precision temperature sensor and a closed-loop constant temperature control system, it monitors the flushing fluid temperature in real time, ensuring it is maintained within the physiologically suitable range of 35-37°C, with an error controlled within 0.5°C. When the temperature exceeds the preset safety threshold, falling below 30°C or rising above 40°C, the control unit 6 automatically triggers an alarm and pauses flushing to prevent bladder spasms due to low temperatures or tissue burns due to high temperatures. The constant temperature device, combined with PID control... The algorithm dynamically adjusts heating / cooling elements to optimize energy efficiency and supports data logging, storing temperature change curves for clinical analysis. This improves patient comfort and reduces discomfort and the risk of complications during irrigation. It also works in conjunction with pressure and flow monitoring modules. The self-made closed drainage device, composed of medical-grade silicone tubing and a sterile collection bag, ensures a completely sealed irrigation process, effectively isolating external contaminants. The device integrates a high-precision pressure sensor to monitor bladder pressure and drainage rate in real time. When the pressure exceeds a preset threshold, it automatically adjusts the drainage speed to prevent mucosal damage or reflux. In bladder irrigation applications, the device supports collaboration with AI vision models and temperature control modules. For example, it can combine bleeding recognition technology to optimize irrigation strategies or maintain stable irrigation fluid drainage under constant temperature control, improving operational safety and patient tolerance.

[0024] Example 3 Furthermore, the color recognition module 8 integrates a color sensor, a light source, and a timer. The color recognition module 8 uses optical principles to detect the color of the liquid. The color recognition module 8 also integrates a temperature sensor. The clamping valve 7 is a proportional electric clamping valve 7, which adjusts the clamping force through voltage or current signals. The control unit 6 performs color recognition based on a deep learning model and supports Wi-Fi and Bluetooth remote communication.

[0025] Specifically, the device of this application can integrate different types of sensors as needed, and construct a closed-loop precision rinsing system through intelligent control algorithms. The enclosed light-shielding structure installs the light source and sensors in an opaque device, which can minimize external light interference and ensure data stability.

[0026] Example 4 Furthermore, this includes the following steps: S1: Acquires flushing fluid color data via an RGB sensor; S2: Classify and subdivide color data to generate control commands; S3: Adjust the clamping force of the clamp valve 7 according to the control command to control the flow rate of the flushing fluid.

[0027] Specifically, the drip rate control of the flushing fluid is achieved using an electrically controlled pinch valve 7. Within the system, the degree of clamping of the pinch valve 7 onto the hose is altered by adjusting the voltage or current control signal. This, achieved through a four-wire distribution of two power lines and two control signal lines, controls the flow rate of the fluid within the hose. The proportional electric pinch valve 7 incorporates integrated motor motion control and drive, eliminating the need for an external controller. During operation, only a single control voltage or current signal is required to adjust the opening and closing of the pinch valve 7 over the inlet tube. First, an RGB sensor determines the presence of blood, then identifies the specific liquid color. Based on these color codes, different control commands are sent via the control unit 6. The pinch valve 7 then applies varying clamping forces according to these commands, thereby controlling the flow rate. Color classification can be set by the customer. The model is trained based on the settings to obtain a detection model. Liquid color is collected using a color sensor, which is equipped with LEDs and an OLED display connected to it. The principle is that different substances absorb and reflect different light. The sensor collects light intensity and projects it onto the corresponding R (red), G (green), and B (blue) sensing areas. AI color recognition is performed on the collected photon data. Then, through code writing, the liquid color level is associated with the control signal. On the one hand, the display screen is controlled to realize automatic color recognition and display. On the other hand, the force of the pinch valve 7 is controlled. The function of the pinch valve 7 is to control the flow rate by squeezing the tube wall. The force is controlled by external information, so the specific drip rate control can be achieved.

[0028] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
