[0002] During the perioperative period of open heart surgery, including the intraoperative extracorporeal circulation stage, postoperative intensive care stage and general ward recovery stage, close monitoring of the patient's urine is a crucial clinical link. As a key window indicator of whether the kidney perfusion is sufficient and whether the heart function is good, the real-time changes in the flow and color of the urine are directly related to the immediate judgment of the medical staff on the patient's circulation state, hemolysis and the risk of acute kidney injury.

[0003] Currently, the medical staff in charge of monitoring needs to observe the amount and color of urine in the urine bag or drainage tube by naked eye and manually record. However, this method highly depends on manual work, not only increases the workload, but also the monitoring accuracy is not very high, manual naked-eye counting is prone to errors, and uninterrupted continuous monitoring cannot be achieved, especially when the medical staff is busy or on shift, key changes are easily missed. Moreover, the judgment of urine color, especially if hemoglobinuria caused by mechanical damage or long-term suction during extracorporeal circulation in open heart surgery is not found in time, depends entirely on the visual observation of medical staff, lacks objectivity and real-time, and may cause serious complications due to delayed intervention.

[0004] In summary, the manual monitoring of urine has technical defects of lack of reliability, low accuracy and poor real-time performance, and how to solve the above technical defects has become a technical problem to be solved. SUMMARY

[0005] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a urine monitoring device.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] To address the technical problems mentioned in the background section, this application combines... Figures 1 to 4 A urine monitoring device was proposed.

[0028] like Figure 1 and Figure 2 As shown, the urine monitoring device 100 provided in this application embodiment includes: a housing 1, the housing 1 including a mounting position 11, the mounting position 11 being detachably connected to a drainage tube 200; an optical detection device 2, disposed inside the housing 1, for detecting urine through the drainage tube 200; an alarm 3, disposed in the housing 1; and a controller 31, electrically connected to the optical detection device 2 and the alarm 3, the controller 31 being used to acquire detection information from the optical detection device 2, wherein the detection information includes at least one of flow information and color information, and the controller 31 is also used to control the alarm 3 to issue an alarm when the detection information meets preset conditions.

[0029] This embodiment provides a urine monitoring device 100 for connection to a drainage tube 200 used to drain urine from a patient. It is characterized by comprising a housing 1, an optical detection device 2, an alarm 3, and a controller 31. The housing 1 constitutes the external support and protection structure of the device, and its interior is hollow to accommodate other components. A mounting position 11 is provided in the housing 1, configured for the drainage tube 200 to pass through and be detachably connected to. This connection can be a tubular channel with a locking mechanism, allowing the drainage tube 200 to be stably locked in and easily removed when needed. The optical detection device 2 is fixedly disposed within the cavity of the housing 1, and its detection optical path is precisely aligned with a section of transparent tube wall of the drainage tube 200 passing through the mounting position 11. The function of the optical detection device 2 is to detect the optical properties of the urine flowing through this section of the tube without contact, through the tube wall.

[0030] In perioperative monitoring during open-heart surgery, the optical detection device 2 begins operation after being installed on the patient's urine drainage tube 200. It continuously emits a light beam of a specific wavelength that penetrates the wall of the drainage tube 200 and the urine inside. As the urine flows, whether continuously or in discontinuous droplets, it modulates the detection beam. The optical detection device 2 converts the received light signal into a real-time changing electrical signal. These electrical signals are transmitted to a controller 31, also located inside the housing 1. The controller 31 is an integrated circuit board electrically connected to the optical detection device 2 and the alarm 3. The controller 31 acquires and processes the raw detection information from the optical detection device 2. Based on set thresholds, the controller 31 can parse flow and color information from this information.

[0031] The controller 31 compares the parsed detection information with thresholds set within the controller 31. These thresholds are based on clinical standards, such as: urine output below 1 mL / (kg·h) or above 2 mL / (kg·h) after cardiopulmonary bypass surgery [urine output after cardiopulmonary bypass surgery should be maintained at 1–2 mL / kg body weight per hour]; urine output below 0.5 mL / (kg·h) or above 1 mL / (kg·h) after non-cardiopulmonary bypass surgery [the standard urine output for ordinary non-cardiopulmonary bypass surgery is usually 0.5–1 mL / kg body weight per hour]; 24-hour urine output exceeding 2500 ml; urine output less than 400 ml in 24 hours; or urine output less than 17 ml per hour; urine output less than 100 ml in 24 hours; or no urine output within 12 hours; or when the urine color changes abruptly from the normal color range to the red spectrum range, and then corrects back to the normal color range, the alarm conditions are met. Once any preset condition is met, the controller 31 will send a command to the alarm 3. Alarm 3 is a buzzer. Upon receiving a command, alarm 3 immediately sounds an alarm to alert medical staff.

[0032] Therefore, this embodiment integrates the optical detection device 2, controller 31, and alarm 3 into a housing 1 detachably connected to the standard drainage tube 200, constructing an automated closed-loop monitoring system. In the complex working environment of the operating room or intensive care unit, the optical detection device 2 achieves objective and continuous detection of urine flow and color, eliminating subjective errors caused by manual counting and misjudgments due to visual fatigue. The controller 31 processes data and executes logical judgments in real time, solving the problems of manual monitoring not being able to operate 24 hours a day and being prone to omissions during shift changes. Finally, the alarm 3 actively alarms when clinical danger thresholds are reached, transforming the need for proactive discovery of key information into proactive push notifications, shortening the response time from the occurrence of abnormalities to medical staff intervention. This urine monitoring device 100 solves the technical defects of low reliability and poor real-time performance in existing technologies, providing a precise means of urine monitoring for patients in the perioperative period of open-heart surgery.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments of this application, a throttling device 4 is included. The throttling device 4 is disposed in the drainage tube 200 and is used to throttle the drainage tube 200 so that the urine passing through the detection area of ​​the optical detection device 2 is in the form of water droplets.

[0034] In this embodiment, the throttling device 4 is installed on the drainage tube 200, located near the upstream or downstream section of the drainage tube 200 at the mounting position 11 of the housing 1. The throttling device 4 can reduce the flow area of ​​the drainage tube 200 by contacting it, that is, it can create a controllable flow resistance to the urine flowing through it by limiting the orifice diameter, causing the urine that should have flowed continuously to fall downwards in a droplet shape, thus achieving the throttling effect on the drainage tube 200.

[0035] When droplets of urine pass through the detection area, each droplet briefly blocks the light beam of the optical detection device 2. The controller 31 counts these standardized pulse signals to calculate the number of droplets passing through per unit time. Since the volume of each droplet is essentially constant under the same pipeline conditions, the real-time urine flow rate can be calculated after calibration. Therefore, by setting the throttling device 4 to force the urine to dropletize, an easily identifiable signal source is created for optical flow detection, solving the problem of blurred optical detection signals and large flow measurement errors caused by continuous liquid flow at low urine flow rates.

[0036] As can be seen, the throttling device 4, by throttling, diverts the continuous urine flow into discrete droplets. This structural feature works closely with the optical detection device 2 in the continuous operation of urine monitoring, enabling the optical detection device 2 to generate clearer flow signals and improving the real-time performance, accuracy, and reliability of urine flow monitoring in clinical settings.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the optical detection device 2 is a digital RGB color sensor, and the flow information is the number of drops of urine flowing through the detection area per unit time. The preset conditions include that the number of drops of urine flowing through the detection area per unit time is greater than or equal to a first threshold, which corresponds to the control alarm 3 issuing a polyuria alarm. The preset conditions also include that the number of drops of urine flowing through the detection area per unit time is less than or equal to a second threshold, which corresponds to the control alarm 3 issuing a oligouria alarm.

[0038] In this embodiment, an RGB color sensor is fixedly installed inside the housing 1. Its detection end is precisely aligned with the detection area of ​​the drainage tube 200 at the mounting position 11. Utilizing the light-blocking effect caused by urine droplets passing through, electrical pulses are generated. The controller 31 counts these pulses to obtain the number of urine droplets flowing through the detection area per unit time, providing flow rate information. Secondly, during the non-blocking period, the sensor emits RGB mixed light and analyzes the spectrum after urine reflection, outputting color information.

[0039] The controller 31 has two preset alarm conditions related to urine flow rate. Clinically, polyuria is defined as a 24-hour urine output exceeding 2500 ml, oliguria as a 24-hour urine output less than 400 ml, or a urine output less than 17 ml per hour, and anuria as a 24-hour urine output less than 100 ml, or no urine output within 12 hours. Since 15 drops are typically defined as 1 ml, a first threshold of 26 drops per minute or more is set, and a second threshold of 5 drops per minute or less is set. The condition is met when the calculated number of drops per unit time is consistently higher than or equal to a set first threshold, and vice versa. The first threshold is set at a higher urine flow rate level to indicate polyuria, and the second threshold is set at a lower urine flow rate level to indicate oliguria or anuria. The controller 31 continuously compares the real-time calculated number of drops per unit time with these two thresholds.

[0040] It is evident that the optical detection device 2 not only provides continuous and objective monitoring capabilities, but also further realizes intelligent identification and classification of clinical risks, improving the real-time performance, accuracy, and clinical guidance value of urine monitoring in patients undergoing open-heart surgery.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the throttling device 4 includes a first throttling device 41 and a second throttling device 42, with the first throttling device 41 located upstream of the detection area and the second throttling device 42 located downstream of the detection area.

[0042] In this embodiment, the throttling device 4 consists of two independent throttling components: a first throttling device 41 and a second throttling device 42, connected in series on the drainage tube 200 to regulate the resistance to urine flow. The first throttling device 41 is installed upstream of the detection area of ​​the optical detection device 2, i.e., on the section of the drainage tube 200 before urine flows into the detection area. The second throttling device 42 is installed downstream of the detection area of ​​the optical detection device 2, i.e., on the section of the drainage tube 200 after urine flows out of the detection area. The flow direction of urine along the drainage tube 200 is as follows: first throttling device 41, detection area, second throttling device 42.

[0043] By combining the first throttling device 41 and the second throttling device 42, a more stable environment is created for the optical detection area. The upstream throttling effect suppresses input fluctuations, while the downstream throttling effect balances output disturbances. This allows the urine flowing through the detection area to remain droplet-shaped, and the droplet flow rate and morphology become more consistent, maintaining the stability of droplet formation and the quality of the detection signal within the detection area. This ensures the accuracy of droplet counting and the reliability of colorimetric data acquisition in dynamically changing clinical environments.

[0044] It can be seen that the structural features of the first throttling device 41 and the second throttling device 42, located on the upstream and downstream sides of the detection area respectively, optimize the flow state of urine in the key detection section and reduce the interference caused by upstream pressure fluctuations and downstream siphon force changes to the detection process.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the throttling device 4 includes a retaining ring 43, which is detachably fitted onto the drainage tube 200.

[0046] In this embodiment, the main structure of the throttling device 4 is a ring-shaped mechanical component, whose function is to apply external radial constraint to the drainage tube 200 to achieve throttling. The retaining ring 43 is directly sleeved on the outer wall of the drainage tube 200 through its ring structure. The connection between the retaining ring 43 and the drainage tube 200 is detachable. The retaining ring 43 can slide along the axial direction of the drainage tube 200 to adjust its position, or can be directly removed from the drainage tube 200 without disconnecting or cutting the drainage tube 200. The inner diameter of the retaining ring 43 is slightly smaller than the outer diameter of the drainage tube 200 in its free state. When the retaining ring 43 is sleeved and locked on the drainage tube 200, it squeezes the wall of the drainage tube 200 inward, causing a local narrowing of the cavity of the drainage tube 200 at that point, forming a throttling point.

[0047] Therefore, the retaining ring 43 provides a flexible and easily adjustable method for throttling, allowing for quick installation, adjustment, or removal of the throttling point outside the drainage tube 200, thus conveniently controlling the dripping effect of urine. This enhances the device's versatility and adaptability to different tubing specifications and patient conditions, and also makes on-site fine-tuning of the detection signal quality possible during real-time monitoring, thereby further ensuring the stability and reliability of flow and color information acquisition.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the throttling device 4 further includes a screw 44, which passes through the retaining ring 43 and extends in the radial direction of the retaining ring 43.

[0049] In this embodiment, the screw passes through the ring body of the retaining ring 43. The ring body of the retaining ring 43 has a through hole with internal threads. The screw 44 engages with the internal threads of the through hole through its external threads, thereby achieving a through-connection. The axial extension direction of the screw 44 is set to be along the radial direction of the retaining ring 43, which means that when the screw 44 is screwed in, its end points perpendicularly to the drainage tube 200 fitted by the retaining ring 43.

[0050] After the retaining ring 43 is fitted onto the outside of the drainage tube 200, medical staff can finely adjust the throttling level by rotating the screw 44. Since the screw 44 extends radially along the retaining ring 43, when it is screwed in, the end of the screw 44 moves radially inward, directly pressing against or further squeezing the wall of the drainage tube 200. Conversely, when the screw 44 is unscrewed, its pressure on the tube wall decreases. The threaded drive of the screw 44 converts rotational motion into precise linear displacement, allowing the radial pressure applied to the drainage tube 200 to vary linearly.

[0051] Therefore, by adding a screw 44 extending radially and passing through the retaining ring 43, the adjustment of the throttling degree is upgraded from a snap-locking mechanism to a precisely controllable threaded drive. This allows medical staff to finely adjust the degree of compression of the drainage tube 200 on-site based on the quality of the actual detection signal, thereby accurately controlling the state of urine dripping, optimizing the working conditions of the optical detection device 2, and improving the device's adaptability and adjustment accuracy under different patient individual differences, different urine characteristics, and dynamically changing clinical conditions.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the optical detection device 2 includes a digital RGB color sensor and an optical cross-correlation flow sensor, and the flow information is the flow rate value of urine flowing through the detection area.

[0053] In this embodiment, the optical detection device 2 consists of two functionally independent sensor components, which are integrated together or installed side by side within the housing 1, with their detection ends aligned with the same detection area or adjacent detection sections of the drainage tube 200. These two components are a digital RGB color sensor and an optical cross-correlation flow sensor, respectively.

[0054] The function of a digital RGB color sensor is to acquire color information from urine. It emits a mixture of light containing the three primary colors of red, green, and blue, and receives the spectrum after it is transmitted or reflected by the urine. The internal circuitry of the sensor quantizes this spectral signal into three independent digital values ​​representing the intensity of the red, green, and blue components, thus providing an objective and quantitative description of the urine color.

[0055] An optical cross-correlation flow sensor is used to acquire flow information, consisting of a light emitter and a photodetector arranged at known minute distances along the direction of urine flow. As urine flows past these two detection points, it causes similar but time-delayed fluctuations in the received light signals. By calculating the cross-correlation function between these two signals, the time required for urine to flow a known distance can be determined, thus calculating the flow rate. Based on this flow rate and the known inner diameter cross-sectional area of ​​the drainage tube 200, the controller 31 can directly calculate the quantified flow rate of urine flowing through the detection area, providing more direct and clinically accurate urine flow data compared to simply counting droplets.

[0056] Therefore, by specifically configuring the optical detection device 2 as a combination of a digital RGB color sensor and an optical cross-correlation flow sensor, the monitoring of both urine color and flow rate parameters is achieved. The digital RGB color sensor provides objective and quantitative color analysis, overcoming the subjectivity of human visual inspection, while the optical cross-correlation flow sensor provides quantitative flow rates that are more closely aligned with clinical diagnosis and treatment decisions, reducing potential conversion errors when high-precision quantitative monitoring is required. The combination of these two components, without imposing strict requirements on the urine flow pattern, provides the technological foundation for achieving highly reliable, high-precision, and highly objective automated urine monitoring.

[0057] like Figure 1 and Figure 3 As shown, in some embodiments of this application, the preset conditions include color information indicating that the urine contains red.

[0058] In this embodiment, the controller 31 defines the preset conditions as color information indicating that the urine contains red, and transforms the abnormal color state that requires timely intervention in clinical practice into a technical signal that the device can recognize objectively and in real time.

[0059] Clinically, red urine after cardiopulmonary bypass should raise concern, as it is usually a sign of hemoglobinuria, which may be related to red blood cell destruction, kidney damage, or perfusion problems.

[0060] For example, during cardiopulmonary bypass in open-heart surgery, mechanical injury or prolonged suction can lead to hemolysis, causing hemoglobin to enter the urine. Similarly, kidney injury can also cause hemoglobin to enter the urine; thrombosis, embolism, or hypotension can reduce renal blood flow, leading to hypoxic kidney injury. Furthermore, insufficient perfusion, inadequate flow, or poor drainage can directly affect urine volume and color.

[0061] Therefore, by specifically defining and pre-setting conditions, including the judgment of the specific color abnormality of urine containing red, the urine monitoring device 100 is endowed with an automated and objective early warning capability for clinical risk indicators, especially timely detection of hemoglobinuria caused by hemolysis. This replaces the visual observation method that relies entirely on medical staff, solves the technical problems of the lack of objectivity and real-time performance of the visual observation method, and thus achieves the technical effect of improving the automation level and monitoring accuracy of urine monitoring.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the housing 1 includes a mounting groove adapted to the drainage tube 200, the mounting groove forming a mounting position 11, and the housing 1 is also provided with a locking device 5, which is used to lock the drainage tube 200 in the mounting groove.

[0063] In this embodiment, the mounting groove is a recessed structure inside the housing 1. Its shape and size are specially designed to fit the drainage tube 200. The radius of curvature of the arc-shaped bottom surface of the mounting groove matches the outer diameter of the drainage tube 200. The width of the groove is slightly larger than the diameter of the drainage tube 200, so that a section of the drainage tube 200 can be laterally embedded and accommodated in the groove, providing a preliminary positioning and bearing space for the drainage tube 200.

[0064] The locking device 5 is a separate mechanical component or a movable structure integrally formed with the housing 1. Its mounting position 11 is associated with the mounting groove and is usually located above the mounting groove. The function of the locking device 5 is to mechanically fix the drainage tube 200 after it is placed into the mounting groove, that is, to lock the drainage tube 200 in the mounting groove and prevent the drainage tube 200 from accidentally coming out of the mounting groove or shifting.

[0065] During installation, medical personnel first align and press the section of the drainage tube 200 to be monitored into the mounting groove of the housing 1. The fitting shape of the mounting groove ensures that the drainage tube 200 is in place and that the area to be monitored on the tube wall is aligned with the window of the optical detection device 2 inside the housing 1. Then, the locking device 5 is operated. The locking force applied by the locking device 5 securely restrains the drainage tube 200 within the mounting groove, reducing the possibility of axial movement and radial displacement. This stable connection ensures that the relative position between the drainage tube 200 and the optical detection device 2 remains stable under common clinical conditions such as patient movement, slight pulling of the tubing, or accidental impact to the equipment. The optical detection window is always aligned with the urine flow within the drainage tube 200, preventing deviation of the detection area or signal interruption due to tubing slippage.

[0066] Therefore, by defining the mounting position 11 as a mounting slot for the drainage tube 200 and adding a locking device 5 for fixing the drainage tube 200, a stable, reliable, and easy-to-operate tubing connection solution is provided. This structure solves the problem that the connection between the monitoring device and the drainage tube 200 may become loose or detached due to external forces in complex clinical environments, ensuring that the optical detection device 2 can continuously and stably align with the urine flow in the drainage tube 200 for detection, thus guaranteeing the continuity of automated monitoring and the reliability of data.

[0067] like Figure 1 and Figure 3 Figure 1 Figure 4 As shown, in some embodiments of this application, a display 6 and a data interface 7 are included. The controller 31 is electrically connected to the display 6 and the data interface 7. The display 6 is used to display flow information, color information and alarm information, and the data interface 7 is used to connect to monitoring equipment.

[0068] In this embodiment, the urine monitoring device 100 also includes a display 6 and a data interface 7. The display 6 is a small liquid crystal display screen, which is integrated and mounted on the outer surface of the housing 1 for easy viewing by medical personnel. The data interface 7 can be a physical port, which is located on the side or end of the housing 1. Both components are electrically connected to the controller 31, and are connected to the main control circuit board of the controller 31 through internal circuitry, receiving instructions from the controller 31 and transmitting data.

[0069] The function of display 6 is to visually present information. During the continuous operation of the device, the controller 31 processes the flow information, color information, and alarm information in real time, converts them into text format, and drives display 6 to display them. This allows medical staff to intuitively understand the real-time parameters and historical trends of urine without relying on a single audible and visual alarm.

[0070] Data interface 7 is used to connect to monitoring equipment. By connecting data interface 7 to the monitor, the controller 31 transmits the processed flow information, color information, alarm information, and raw detection data to the monitoring equipment according to the agreed communication protocol. This allows urine parameters to be centrally monitored, recorded, and correlated with other key vital signs such as heart rate, blood pressure, and blood oxygen saturation.

[0071] Therefore, the display 6 and data interface 7 enhance the human-computer interaction and data integration capabilities of the urine monitoring device 100. The display 6 provides real-time data visualization, and the data interface 7 enables connection to external monitoring systems, facilitating automatic data recording, centralized monitoring, and remote alarms. This solves the problems of tedious and error-prone manual recording, achieving recordable, traceable, and integrable monitoring data, thereby improving monitoring efficiency and protecting patient health.
