Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a color-recognizable multi-channel liquid output monitoring device. Background Art

[0002] Fluid output monitoring is an important part of medical care, especially in postoperative management, intensive care and diagnosis and treatment of urinary system diseases. Fluid output monitoring can provide important physiological index information for patients. Urine is an important excretion of human metabolism. Its flow and color can not only reflect kidney function and bladder function, but also indicate pathological changes in the urinary system.

[0003] At present, the existing technology can monitor the patient's urine discharge through a monitoring device, specifically by measuring the flow rate and total amount of the patient's urine through a flow sensor. The flow data is mostly used to judge bladder function, urinary tract obstruction and fluid balance. However, most of the current monitoring devices focus on the collection of flow data, while the monitoring of urine color mostly relies on manual observation or offline analysis, which makes it difficult to achieve real-time, automatic color change monitoring; and most of the current catheterization channels are single-channel, and urine is collected into a urine storage bag through a single channel, resulting in urine at different times being collected together, making it difficult to observe and sample urine at the same time or at different time periods according to current different needs. Although the patent with application number CN119318509A discloses a urine sampler, which discloses that four shunt tubes are fixedly installed inside the mounting shell, and the patient's urine is gathered and shunted by opening and closing on time to achieve storage and sampling in different time periods, for patients with intubation and urination, since urination is difficult to control, there will be continuous urine discharge in the urination tube. It is difficult to obtain valuable urine samples only by opening and closing on time to collect urine at different time periods unless there are a large number of shunt tubes.

[0004] In response to the above problems, there is an urgent need for a device that can realize multi-channel liquid output monitoring, real-time urine color recognition and flow data analysis. It uses flow sensors and optical sensors to dynamically associate multiple urinary channels, and preserve urine samples when abnormal urine is identified in the patient. It realizes high-precision, multi-dimensional and intelligent liquid output monitoring methods, providing reliable technical support for patient care and disease diagnosis. Summary of the invention

[0005] This application aims at the problem that most current monitoring devices focus on the collection of flow data, which makes it difficult to achieve real-time and automatic color change monitoring; and most of the urinary catheterization channels are single-channel, which makes it difficult to identify changes in urine at different time periods, and it is also difficult to sample urine at different time periods. A device that can achieve multi-channel liquid output monitoring, real-time urine color recognition and flow data analysis is provided. Through flow sensors and optical sensors combined with multiple urinary tract channels, a high-precision, multi-dimensional, intelligent liquid output monitoring method is provided. The specific technical solution is as follows:

[0006] In a first aspect of the present application, a color-recognizable multi-channel liquid output monitoring device is provided, comprising a monitoring system, wherein the monitoring system comprises:

[0010] The sample collection module is provided with a plurality of sub-channels on the urinary catheterization channel, each sub-channel is provided with a first switch, and the first switch is turned on when abnormal urine flow and / or urine color is identified, so that urine enters the sub-channel for sample retention.

[0011] In one embodiment of the present application, the sample collection module also includes a conventional collection submodule, which opens and closes the corresponding first switches one by one according to the arrangement order of the sub-channels at a predetermined time, compares the urine color changes of adjacent sub-channels through an optical sensor, and when it belongs to the normal change range, opens the second switch set on each sub-channel to discharge the urine in the sub-channel back to the urinary catheterization channel.

[0012] In one embodiment of the present application, a pressure monitoring module is further included, wherein a pressure sensor is arranged at one end of the urinary catheter channel inserted into the bladder, and the pressure sensor is used to measure the pressure data in the patient's bladder;

[0013] The data comparison module compares the pressure data with the standard pressure of a normal bladder to determine whether the pressure data is abnormal; when the pressure data monitored by the alarm processing module exceeds the set normal range, an alarm is issued through the alarm device to alert medical staff and / or patients to pay attention and take measures.

[0014] The pressure monitoring module further includes a feedback sub-module that dynamically displays the pressure data and the real-time data of the urine flow to medical staff and / or patients through a visualization device, sets the pressure data and the urine flow as associated data, and presets that the pressure data in different data segments corresponds to the urine flow in different data segments. When an abnormality occurs, it alerts medical staff and / or patients to pay attention and take measures.

[0015] In an embodiment of the present application, the feedback sub-module further includes a functional training sub-sub-module that stimulates the bladder area through an auxiliary device at a preset time and when the pressure data reaches a preset value, induces a reflexive contraction of the detrusor muscle, and simultaneously records the patient's bladder capacity, pressure changes, and urine emptying data to generate a personalized bladder function recovery suggestion, and correspondingly adjusts the preset time and the preset value of the pressure data.

[0016] In an embodiment of the present application, the sample collection module further includes a segmented discharge sub-module configured to control the phased collection of urine during the planned urination process of the functional training sub-sub-module, including:

[0017] A front-segment discharge unit configured to turn on all second switches of the sub-channels when urination is initiated, and simultaneously turn on the first switch of the sub-channels one by one, and only one first switch is turned on at the same time;

[0020] In an embodiment of the present application, during the process of bladder function recovery, the functional training sub-module further includes setting a biochemical sensor in the anti-blocking channel to detect key biochemical indicators in urine in real time, including the pH value of urine, red blood cell concentration, protein concentration, and inflammatory factors; fusing and analyzing the collected biochemical indicators with bladder pressure, urine flow rate, and color data to establish a health assessment model; using the health assessment model to determine in real time whether there is a situation where the current stimulation causes abnormal bladder training; when the current stimulation causes abnormal bladder training, automatically adjusting the working parameters of the auxiliary device, including stimulation intensity, duration, and mode, and sending out a warning signal to prompt medical staff to intervene and adjust; at the same time, generating personalized bladder function recovery suggestions according to the dynamic changes of biochemical indicators to guide the adjustment of subsequent training programs.

[0021] In an embodiment of the present application, it further includes a personalized management module for obtaining the normal urine flow rate standard and urine color standard of the current patient, specifically by obtaining the medical data of the current patient, where the medical data includes patient physical sign data and the diseases suffered, and obtaining the current urine flow rate standard and color standard of the current patient through the medical data.

[0022] In an embodiment of the present application, the medical data further includes prescription data. According to the prescription data, the types of drugs and the liquid input volume are obtained, and the urine flow rate standard and urine color standard are adjusted according to the urine color change and urine volume change caused by using the types of drugs. At the same time, the urine flow rate standard is adjusted according to the liquid input volume.

[0023] In an embodiment of the present application, the personalized management module further includes obtaining the work and rest time and medication time of the patient, obtaining the sampling times of nocturia, morning urine, and routine urine according to the work and rest time, obtaining the sampling times of routine urine and urine after medication according to the medication time, opening the switch corresponding to the sub-channel at the sampling time, and recording the sub-channel into which the urine enters, and closing the switch corresponding to the sub-channel after sampling is completed.

[0024] In the second aspect of the present application, there is also provided a multi-channel liquid output monitoring device capable of recognizing colors, including:

[0025] A channel component, including a urinary catheterization channel, one end of the urinary catheterization channel enters the bladder through the urethra, and the other end is connected to a urine storage bag;

[0026] A sensor component, monitoring the urine flow rate of the urinary catheterization channel through a flow sensor and monitoring the urine color of the urinary catheterization channel through an optical sensor; comparing with the standard flow rate and standard color range of normal urine;

[0027] A communication alarm component that, when the monitored urine flow rate and / or urine color exceed the normal range, issues an alarm through an alarm device to alert medical staff and / or patients to pay attention and take measures; at the same time, it sends the urine discharge report and comparison results to the doctor's end;

[0028] A sample collection component, with multiple sub-channels provided on the urinary catheterization channel, and each sub-channel is provided with a first switch, which is turned on when it is recognized that the urine flow rate and / or urine color is abnormal, allowing urine to enter the sub-channel for sampling.

[0029] The present application has the following beneficial effects:

[0030] 1. The urine flow rate in the channel is collected by the flow sensor, and the color data in the channel is collected by the optical sensor. The system compares with the urine flow rate standard and urine color standard in real time and automatically. When it is recognized that the patient's urine is different from the standard, the alarm device alerts medical staff and / or patients to pay attention and take measures, avoiding the further development of abnormal conditions and enabling early treatment; through the multi-channel setting, it is avoided that a single-channel urinary catheter directly collects urine at different times into the urine storage bag, making it difficult to observe, sample, etc. the urine at the same time or at different time periods. Specifically, according to requirements, urine at the same time can enter multiple sub-channels respectively to obtain multiple identical samples, facilitating sampling and detection; or separate samples can be left in the sub-channels without being mixed with normal urine at other times, improving the representativeness of the samples and the accuracy of the detection results, providing reliable technical support for patient care and disease diagnosis; in the prior art, although time-segmented preservation has been achieved, the number of sub-channels and the storage capacity are limited. However, the urine discharge of intubated patients at the initial stage is continuous, and the time when abnormal urine appears is also uncertain. Therefore, to not miss abnormal urine with test value, a large number of sub-channels are required to achieve full coverage of the collection time through sub-channels, but this makes the whole device bulky and the cost increase; or medical staff need to frequently process the urine in the sub-channels, increasing the workload of medical staff, and no matter how it is set, since the sub-channels are opened and closed according to preset time, although abnormal urine is collected in the sub-channels, there will basically be some normal urine in it, making it difficult to achieve targeted collection of abnormal urine; while in the present application, through the setting of the sample collection module, multiple sub-channels are provided on the urinary catheterization channel. Different from the prior art of using multiple channels to save urine in time segments, the sub-channels in the present application are combined with the alarm processing module, and when it is recognized that the patient's urine is abnormal, the sub-channels are opened for sample collection. This design realizes targeted preservation of abnormal urine and can effectively reduce the number of sub-channels;

[0031] 2. Mechanical timing devices and / or signal control devices are set for the first switch and the second switch of the sub-channels. By presetting and / or remotely controlling the opening and closing of different sub-channel switches, urine enters the sub-channel with the first switch open within a preset time, and urine is discharged from the sub-channel with the second switch open within a preset time. By setting different switch logics, different types of urine samples are obtained in the sub-channels. For example, when multiple sub-channels are opened simultaneously, the urine samples in the multiple sub-channels are the same. Only one sub-channel is opened, filled, and then closed, and the next sub-channel is opened. According to the sorting of the sub-channels, the change in the color of the patient's urine can be more intuitively seen. On the basis of opening the sub-channel after an abnormality is identified, this application supplements the conventional collection function. Because for patients who urinate through a catheter initially, the urine discharge is continuous and slow, so the amount of urine in the catheterization channel is not much, and it is relatively difficult to identify the change in color. Therefore, this application concentrates the urine in the sub-channels and compares the urine in adjacent sub-channels to identify the change in urine color within a similar time. If an abnormality occurs, the urine is preserved. If there is no abnormality, the urine returns to the catheterization channel through the second switch and enters the urine storage bag. At the same time, the flow rate of the catheterization channel collected by the flow sensor can be compared with the sum of the flow rates of the sub-channels with the switches open. If the sum of the flow rates of the sub-channels is less than the flow rate of the catheterization channel, an inspection is carried out to avoid liquid leakage or poor circulation due to blockage of the sub-channels. Further, by presetting and / or remotely controlling the opening and closing of the switches, urine samples of patients at specific times, such as morning urine and night urine, can be collected without increasing the workload of medical staff.

[0032] 3. By setting a pressure sensor at the end of the catheterization channel that enters the bladder, the monitoring of the pressure data in the patient's bladder is realized. First, when the abnormal pressure data is recognized, medical staff and / or patients are notified and reminded to pay attention and deal with it to avoid the bladder pressure being in an abnormal state for a long time. Further, the pressure data and the real-time data of the urine flow rate are dynamically displayed to medical staff and / or patients through a visualization device, so that patients and medical staff can more intuitively obtain and understand their own physical sign data. By combining the pressure data with the urine flow rate, when there is no corresponding change between the two, an alarm is sent to notify and remind medical staff and / or patients to pay attention and check whether there is an abnormality.

[0033] 4. The patient undergoes bladder training in the later stage of indwelling catheterization to gradually restore the bladder capacity, micturition reflex, and autonomous micturition function. At the preset time and when the preset value of the pressure data is reached, the bladder area is stimulated through an auxiliary device to induce reflexive contraction of the detrusor muscle. Meanwhile, the patient's bladder capacity, pressure changes, and urine emptying data are recorded to generate personalized bladder function recovery suggestions, and the preset time and the preset value of the pressure data are adjusted accordingly; gradually achieve the autonomous micturition function of the bladder. The specific technical solutions include:

[0034] Early intervention in bladder function: In the later stage of indwelling catheterization, evaluate the patient's bladder function. When the patient's bladder function has not been completely lost, use the monitoring and training system to gradually enhance the bladder function and reduce the risk of micturition disorders after the catheter is removed.

[0035] Provide personalized training guidance: According to the patient's bladder filling ability, micturition time, and urine flow characteristics, design a personalized bladder training plan to gradually improve the detrusor muscle contraction ability and sphincter control ability.

[0036] Promote the recovery of nerve reflexes: Through physical stimulation, including electrical stimulation, or behavioral intervention, including micturition guidance and feedback, reactivate the micturition reflex arc and improve the nerve's control ability over the bladder. Specifically, the patient views their own bladder pressure through the visualization device and induces micturition when the predetermined pressure is reached;

[0037] Through early training, problems such as urinary retention or urinary incontinence caused by bladder dysfunction can be reduced, and the need for the patient to reinsert the catheter can be avoided; it can help the patient recover autonomous micturition as early as possible, relieve the psychological and physiological burden of long-term dependence on the catheter, and effectively improve the patient's quality of life; at the same time, micturition problems after catheter removal may increase the risk of urinary tract infection, and bladder training helps reduce these complication risks.

[0038] 5. Considering that the urination of intubated patients during later training is planned urination, which is different from the continuous and slow urination when they are first intubated. Planned urination stores urine for a period of time and then discharges it concentratedly, enabling the patient's bladder to achieve functional training recovery before extubation. Therefore, during the urine storage process, there is no continuous urine flow in the urinary catheter, making it easier for bacteria to breed. During concentrated urination, these bacteria may be carried into the sample together, resulting in different numbers of bacteria in the sample and the actual urine of the patient, causing inaccurate data. Therefore, in this application, during concentrated urination, the front section of urine is discarded, and all switches are turned on simultaneously. The urinary catheter is flushed through the front section of urine. Specifically, when urination is initiated, the central controller simultaneously turns on the second switches of all sub-channels and turns on one first switch one by one to form a flushing path. The first switch adopts a sequential pulse opening mode (for example, switching one sub-channel every 200 ms) to ensure that the flushing fluid flow covers the inner walls of all sub-channels. When the front section of urine is discharged, that is, after the catheterization channel and sub-channels are all flushed, a flushing completion signal is generated. The volume of the front section of urine is determined according to the sub-channel data and the length of the catheterization channel. Specifically, the determination model for the volume of the front section of urine is:

[0039]

[0040] where V i is the volume of the i-th sub-channel (preset value), k is the wall adhesion coefficient (default 0.15), L is the real-time length of the catheterization channel. After the front section of urine is emptied, the middle and rear sections of urine are retained as samples. Through the hierarchical design of flushing the catheterization channel and sub-channels by emptying the front section of urine, the problem of bacterial interference in the planned urination mode is solved.

[0041] 6. By introducing biochemical index monitoring to comprehensively monitor the bladder state, not limited to single mechanical data, it can more comprehensively reflect the health status of the bladder tissue, timely detect potential inflammation or metabolic abnormalities, and thus prevent secondary injuries that may be caused by the stimulation training method. The intelligent analysis after data fusion can achieve real-time and dynamic feedback regulation, ensuring that the auxiliary device can effectively activate the detrusor muscle and avoid tissue fatigue or injury caused by excessive stimulation, realizing personalized rehabilitation training in the true sense. At the same time, through real-time monitoring and comprehensive data analysis, the system can detect abnormal states earlier, timely adjust the treatment strategy, and thus significantly improve the overall bladder function recovery effect and patient safety.

[0042] 7. Obtain the medical data of the patient. According to the disease the patient suffers from, the treatment stage, and the medications used, specify corresponding personalized urine flow standards and color standards, which can effectively improve the accuracy of alarms and reduce the workload of medical staff caused by false alarms and the disturbance of the patient's rest. Further, obtain the prescription data of the patient, including the types and amounts of fluids input by the patient every day. The more fluids are input, the corresponding urine output will increase. Otherwise, the patient will have adverse reactions such as edema. When there are diuretic components in the medications or the medications cause urine color changes, the urine volume will increase or the urine color will change. Therefore, adjust the urine color standard and the urine flow standard according to the types and amounts of fluids input by the patient every day.

[0043] 8. Obtain the patient's work and rest time and medication time. Specifically, the patient and medical staff can input the work and rest types and times, as well as the medication time into the system. It can also automatically identify the patient's daily sleep, waking up, and taking medications through an image acquisition device. When corresponding samples are needed, including nocturia, morning urine, routine urine, and urine after taking medications, according to the patient's work and rest time and medication time, select the switch corresponding to the sub-channel to be opened at the corresponding time, and close it after sampling, waiting for the medical staff to pick it up. Combining the setting of the sub-channel, it is more convenient to obtain the corresponding type of sample urine. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0056] The solution of the present application will be further described below with reference to the accompanying drawings.

[0057] As Figure 1 shown, the electronic device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to implement connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0058] Those skilled in the art can understand that Figure 1 the structure shown in

[0059] As Figure 1As shown, the memory 1005, which is a storage medium, may include an operating system, a network communication module, a user interface module, and a data storage module.

[0060] In Figure 1 the electronic device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the electronic device of the present invention may be arranged in the electronic device, and the electronic device calls, through the processor 1001, a multi-channel liquid output monitoring device capable of identifying colors stored in the data storage module of the memory 1005, and executes the liquid output monitoring system of the present application.

[0061] Based on the foregoing hardware operating environment and system architecture, in the first aspect of the present application, with reference to Figure 2 、 Figure 3 and Figure 4 shown, a multi-channel liquid output monitoring device capable of identifying colors is provided, including a monitoring system, and the monitoring system includes:

[0062] A channel drainage module, configured to collect urine discharged through a urinary catheter channel, one end of the urinary catheter channel enters the bladder through the urethra, and the other end communicates with a urine storage bag;

[0063] A data comparison module, which monitors the urine flow rate of the urinary catheter channel through a flow sensor and monitors the urine color of the urinary catheter channel through an optical sensor; and compares with the standard flow rate and standard color range of normal urine;

[0064] It should be noted that the flow sensor collects the flow rates in different pipelines to obtain the current real-time flow rate of the patient, and further stage flow rates in different time periods can be obtained based on the real-time flow rate; similarly, color data in the channel is collected through the optical sensor to obtain the current urine color of the patient, and further, by comparing the urine colors at different times, the change in urine color is obtained;

[0065] It should be noted that the urine output of normal adults is usually 800 milliliters to 2,000 milliliters per day. For patients with long-term urinary catheterization, the normal hourly urine flow rate should be 30 milliliters per hour to 100 milliliters per hour. If the urine flow rate is lower than 30 milliliters per hour, the patient may have poor urine drainage;

[0066] It should be noted that the normal standard color of urine is light yellow or golden yellow, indicating that the concentration of urochrome (the main pigment in urine) in the urine is moderate, the patient usually has a normal water intake, and there are no obvious pathological problems;

[0067] The alarm processing module, when the monitored urine flow and / or urine color exceeds the normal range, sends an alarm through the alarm device to remind medical staff and / or patients to pay attention and take action; at the same time, the urine discharge report and comparison results are sent to the doctor;

[0068] It should be noted that the alarm device includes bells at the nurse station and the patient's bedside, a central display screen at the nurse station, and other devices that can notify and remind medical staff and / or patients; the doctor's end includes an information receiving device (desktop computer) and / or a mobile device in the doctor's office;

[0069] The sample collection module is provided with a plurality of sub-channels on the urinary catheterization channel, each sub-channel is provided with a first switch, and the first switch is turned on when abnormal urine flow and / or urine color is identified, so that urine enters the sub-channel for sample retention.

[0070] It should be noted that the end of the urinary catheter channel entering the bladder is the same as an existing urinary catheter, such as a three-chamber urinary catheter. Medical staff operate the urinary catheter channel to pass through the urethra into the bladder, and the urine in the bladder is discharged from the body through the urinary catheter channel. The difference between the urinary catheter channel and the three-chamber urinary catheter is that a plurality of branch channels are provided on the channel. When urine passes through the urinary catheter channel, a part of the urine enters the branch channel opened by the first switch.

[0071] In this embodiment, the urine flow in the channel is collected by the flow sensor, and the color data in the channel is collected by the optical sensor. The system compares with the urine flow standard and the urine color standard in real time and automatically. When it is recognized that the patient's urine is different from the standard, the alarm device reminds the medical staff and / or the patient to pay attention and take measures to avoid the further development of abnormal situations and perform treatment as early as possible. Through the multi-channel setting, it is avoided that a single-channel catheter directly collects the urine at different times into the urine storage bag, making it difficult to observe, sample, etc. the urine at the same time or at different time periods. Specifically, according to the needs, the urine at the same time can enter multiple sub-channels respectively to obtain multiple identical samples, which is convenient for sampling and detection; or separate samples can be taken in the sub-channels without being mixed with the normal urine at other times, improving the representativeness of the samples and the accuracy of the detection results, and providing reliable technical support for patient care and disease diagnosis. In the prior art, although segmented storage is achieved, the number and storage capacity of the sub-channels are limited. However, the urine excretion of intubated patients in the initial stage is continuous, and the time when abnormal urine appears is also uncertain. Therefore, in order not to miss the abnormal urine with test value, a large number of sub-channels are required to achieve full coverage of the collection time through the sub-channels. However, such a setting makes the whole device bulky and the cost increases; or it requires medical staff to frequently process the urine in the sub-channels, increasing the workload of the medical staff. And no matter how it is set, since the sub-channels are opened and closed according to the preset time, although abnormal urine is collected in the sub-channels, there will basically be a part of normal urine in it, making it difficult to achieve targeted collection of abnormal urine. In this application, through the setting of the sample collection module, multiple sub-channels are set on the urinary catheterization channel. Different from the prior art of segmentally storing urine through multiple channels, the sub-channels in this application are combined with the alarm processing module. When it is recognized that the patient's urine is abnormal, the sub-channels are opened for sample collection. Such a design realizes the targeted preservation of abnormal urine and can effectively reduce the number of sub-channels;

[0072] Further, according to the abnormal conditions of the urine flow and the color data of the urine, hierarchical alarms are carried out, and the medical staff take corresponding treatment measures; for example, abnormal urine volume includes the abnormal condition of decreased urine volume, oliguria: If the daily urine volume of an intubated patient is less than 400 ml / day or the hourly flow rate is less than 30 ml / hour, it usually indicates that the patient may have problems such as renal insufficiency, dehydration, and urinary tract obstruction. Anuria: If an intubated patient has no urine output at all (urine volume close to 0 ml / hour), it may indicate acute pathological problems such as acute renal failure and urinary tract obstruction, which require emergency treatment. Abnormal condition of increased urine volume: Polyuria: If the urine volume exceeds 2,500 ml / day, possible disease factors such as diabetes, diuretic use, or kidney disease should be considered.

[0073] Abnormal urine color includes dark yellow or amber (mild dehydration): If the urine color is dark, presenting amber or dark yellow, it usually indicates that the patient may be in a state of mild dehydration or insufficient water intake. Special attention should be paid to the fluid balance of intubated patients because long-term catheterization may lead to fluid balance disorders. Transparent or almost colorless (overhydration): If the urine is transparent or almost colorless, it may indicate that the patient has ingested too much fluid, resulting in urine dilution. Long-term overhydration may affect the body's electrolyte balance, especially in patients with weak renal function. Pink or red (hematuria): If the urine of an intubated patient is pink, red, or tea-colored, it usually indicates that the urine contains blood, which may be caused by urinary tract injury, infection, or improper catheter operation. Hematuria may require further examination to rule out urinary tract infection, kidney disease, or catheter-related complications (such as catheter irritation of the bladder wall or bladder injury). Orange or yellow (drugs or bilirubin): Certain drugs (such as antibiotics, vitamin B, etc.) may cause the urine to appear orange or yellow. Bilirubinuria (yellow urine) usually indicates abnormalities in the hepatobiliary system, such as hepatitis, biliary obstruction, etc. If this occurs in an intubated patient, the possibility of drugs or hepatobiliary diseases should be considered. Green or blue (drugs or infection): The urine of an intubated patient being green or blue is usually caused by certain drugs (such as meclor, painkillers, etc.) or infection (such as Pseudomonas aeruginosa infection). If there is no history of drug use, further examination is required to check for urinary tract infection. Milky white (chyluria): Chyluria is usually caused by the entry of lymph fluid into the urine, which may be due to lymphatic vessel injury or infection (such as lymph node enlargement, lymphoma, etc.). If an intubated patient has milky white urine, further diagnosis is usually required.

[0074] Medical staff can take corresponding treatment measures according to the specific abnormalities identified by the system, combined with the patient's medical record data, effectively saving time.

[0075] In an embodiment of the present application, as shown in Figure 5 When the sample collection module further includes a conventional collection sub-module, at a predetermined time, the corresponding first switches are sequentially turned on and off according to the arrangement order of the sub-channels, and the urine color changes in adjacent sub-channels are compared through an optical sensor. When it belongs to the normal change range, the second switches provided on each sub-channel are turned on to drain the urine in the sub-channel back to the urinary catheterization channel.

[0076] In this embodiment, a mechanical timing device and / or a signal control device are set for the first switch and the second switch of the sub-channels. By presetting and / or remotely controlling the opening and closing of different sub-channel switches, urine enters the sub-channel with the first switch open within a preset time, and urine is discharged from the sub-channel with the second switch open within a preset time. By setting different switch logics, different types of urine samples are obtained in the sub-channels. For example, when multiple sub-channels are opened simultaneously, the urine samples in the multiple sub-channels are the same; when only one sub-channel is opened, it is filled and then closed, and the next sub-channel is opened. According to the sorting of the sub-channels, the change in the color of the patient's urine can be seen more intuitively. On the basis of opening the sub-channel after an abnormality is identified in this application, the conventional collection function is supplemented. Because for patients who urinate through an indwelling catheter at the initial stage, the urine discharge is continuous and slow, so the amount of urine in the catheterization channel is not much, and it is relatively difficult to identify the change in color. Therefore, in this application, the urine is concentrated in the sub-channels, and the urine in adjacent sub-channels is compared to identify the change in urine color within a similar time. If an abnormality occurs, the urine is preserved; if there is no abnormality, the urine returns to the catheterization channel through the second switch and enters the urine storage bag.

[0077] At the same time, the flow rate of the catheterization channel collected by the flow sensor can be compared with the sum of the flow rates of the sub-channels with the switches open. If the sum of the flow rates of the sub-channels is less than the flow rate of the catheterization channel, an inspection is carried out to avoid the occurrence of liquid leakage or poor circulation due to blockage of the sub-channels. Further, by presetting and / or remotely controlling the opening and closing of the switches, urine samples of a patient at a specific time, such as morning urine and night urine, can be collected without increasing the workload of medical staff.

[0078] In an embodiment of this application, as shown in Figure 6 it also includes a pressure monitoring module. By setting a pressure sensor at the end of the catheterization channel inserted into the bladder, the pressure sensor is used to measure the pressure data in the patient's bladder.

[0079] The data comparison module compares the pressure data with the standard pressure of a normal bladder to determine whether the pressure data is abnormal. When the pressure data monitored by the alarm processing module exceeds the set normal range, an alarm is issued through the alarm device to remind medical staff and / or patients to pay attention and take measures.

[0080] The pressure monitoring module further includes a feedback sub-module. The pressure data and the real-time data of the urine flow rate are dynamically displayed to medical staff and / or patients through a visualization device. The pressure data and the urine flow rate are set as associated data, and different data segments of the pressure data correspond to different data segments of the urine flow rate. When an abnormality occurs, medical staff and / or patients are reminded to pay attention and take measures.

[0081] It should be noted that patients with indwelling catheters usually cannot urinate independently, and the urination process is usually achieved through an externally inserted catheter. And in the absence of other factors such as urethral obstruction, urination is determined by the pressure of the bladder and the patency of the urethra, rather than active control. The urination process is mainly driven by the filling and pressure changes of the bladder. There is a positive relationship between the pressure in the bladder and the urine flow rate in the catheter. An increase in bladder pressure usually leads to an increase in urine flow rate. Therefore, when there is a change in bladder pressure but no corresponding change in urine flow rate, it is necessary to consider whether there is an abnormality in the patient or the catheter. Factors such as urethral resistance or catheter blockage will affect the urine flow rate. Closely monitoring bladder pressure and urine flow rate is crucial for the prevention and treatment of problems such as bladder dysfunction and urinary tract obstruction;

[0082] In this embodiment, by setting a pressure sensor at one end of the catheterization channel that enters the bladder, the monitoring of the pressure data in the patient's bladder is realized. First, when it is recognized that the pressure data is abnormal, the medical staff and / or the patient are notified and reminded to pay attention and take measures to avoid the bladder pressure being in an abnormal state for a long time; further, the pressure data and the real-time data of the urine flow rate are dynamically displayed to the medical staff and / or the patient through a visualization device, so that the patient and the medical staff can more intuitively obtain and understand their own physical sign data, and combine the pressure data with the urine flow rate. When there is no corresponding change between the two, an alarm is notified to remind the medical staff and / or the patient to pay attention and check whether there is an abnormality.

[0083] In an embodiment of the present application, referring to Figure 7 as shown, the feedback sub-module further includes a functional training sub-module. At a preset time and when the preset value of the pressure data is reached, the bladder area is stimulated through an auxiliary device to induce a reflexive contraction of the detrusor muscle. At the same time, the patient's bladder capacity, pressure changes and urine emptying data are recorded, and a personalized bladder function recovery suggestion is generated, and the preset time and the preset value of the pressure data are correspondingly adjusted.

[0084] It should be noted that the functional degradation that may be caused by long-term indwelling of a catheter includes:

[0085] Bladder deconditioning: Long-term indwelling of a catheter may keep the bladder in a continuously emptied state, and the normal contraction function of the bladder muscle (detrusor muscle) gradually weakens or is lost, resulting in urinary retention or difficulty in urination after the patient removes the catheter.

[0086] Weakening of sphincter function: During the indwelling of the catheter, the urethral sphincter may become weak or lose the ability to control the outflow of urine due to the lack of active control, and urinary incontinence is likely to occur after the catheter is removed.

[0087] Changes in the micturition reflex pathway: The bladder micturition reflex usually depends on complex neural regulation, including the participation of the spinal cord and cerebral cortex. Insertion of a urinary catheter may inactivate the reflex arc, and after removal of the catheter, the patient may be unable to perceive bladder fullness or actively control urination.

[0088] Common micturition problems after removal of the urinary catheter: Difficulty in urination or urinary retention: After the patient's bladder is full, they are unable to initiate urination and need manual compression or reinsertion of the catheter.

[0089] Urinary incontinence: Especially in patients with overactive bladder, involuntary urine leakage may occur due to the failure of the urethral sphincter to regain control.

[0090] Weak micturition force: Due to detrusor muscle weakness, the urine flow rate is low and the micturition time is long.

[0091] In this embodiment, considering to avoid the above problems, the patient undergoes bladder training in the later stage of catheter insertion to gradually restore the bladder capacity, micturition reflex, and autonomous micturition function. At the preset time and when reaching the preset value of the pressure data, the bladder area is stimulated by an auxiliary device to induce reflexive contraction of the detrusor muscle. At the same time, the patient's bladder capacity, pressure changes, and urine emptying data are recorded to generate personalized bladder function recovery suggestions, and the preset time and the preset value of the pressure data are adjusted accordingly; gradually achieve the autonomous micturition function of the bladder; The specific technical solutions include:

[0092] Early intervention in bladder function: In the later stage of catheter insertion, the patient's bladder function is evaluated. When the patient's bladder function has not been completely lost, the monitoring and training system is used to gradually enhance the bladder function and reduce the risk of micturition disorders after removal of the catheter.

[0093] Provide personalized training guidance: According to the patient's bladder filling ability, micturition time, and urine flow rate characteristics, a personalized bladder training plan is designed to gradually improve the detrusor muscle contraction ability and sphincter control ability.

[0094] Promote the recovery of nerve reflexes: Through physical stimulation, including electrical stimulation, or behavioral intervention, including micturition guidance and feedback, the micturition reflex arc is reactivated to improve the nerve's control ability over the bladder. Specifically, the patient views their own bladder pressure through the visualization device and induces micturition when the predetermined pressure is reached;

[0095] Through early training, problems such as urinary retention or urinary incontinence caused by bladder dysfunction can be reduced, and the need for the patient to reinsert the catheter can be avoided; it can help the patient restore autonomous micturition as early as possible, relieve the psychological and physiological burden of long-term dependence on the urinary catheter, and effectively improve the patient's quality of life; at the same time, micturition problems after removal of the catheter may increase the risk of urinary tract infection, and bladder training helps reduce these complication risks.

[0096] In an embodiment of the present application, the sample collection module further includes a segmented discharge sub-module, configured to control the phased collection of urine during the planned urination process of the functional training sub-module, including:

[0097] A front-segment discharge unit, configured to turn on the second switches of all sub-channels when urination starts, and at the same time turn on the first switches of the sub-channels one by one, and only one first switch is turned on at the same time;

[0098] A flushing trigger unit, configured to generate a flushing completion signal after the discharge of the front-segment urine, and the volume of the front-segment urine is determined according to the sub-channel data and the length of the urinary catheterization channel;

[0099] A urine collection unit, in response to the flushing completion signal, turns off the second switch to allow the middle and rear-segment urine to enter the sub-channels set in the sample collection module.

[0100] In this embodiment, considering that the urination of intubated patients during later training is planned urination, which is different from the continuous and slow urination when they are just intubated. Planned urination stores urine for a period of time and then discharges it concentratedly, enabling the patient's bladder to achieve functional training recovery before extubation. Therefore, during the urine storage process, there is no continuous flow of urine in the urinary catheter, which is more likely to breed bacteria. During concentrated urination, these bacteria may be brought into the sample together, resulting in different numbers of bacteria in the sample and the actual urine of the patient, causing inaccurate data. Therefore, in this application, during concentrated urination, the front-segment urine is discarded, and all switches are turned on at the same time to flush the urinary catheter through the front-segment urine; specifically, when urination starts, the central controller synchronously turns on the second switches of all sub-channels and turns on one first switch one by one to form a flushing path. The first switch adopts a sequential pulse opening mode (for example, switching one sub-channel every 200 ms) to ensure that the flushing fluid flow covers the inner walls of all sub-channels; when the discharge of the front-segment urine ends, that is, when the urinary catheterization channel and the sub-channels are all flushed, a flushing completion signal is generated. The volume of the front-segment urine is determined according to the sub-channel data and the length of the urinary catheterization channel. Specifically, the front-segment urine volume determination model:

[0101]

[0102] Among them, V i is the volume of the i-th sub-channel (preset value), k is the wall adhesion coefficient (default 0.15), L is the real-time urinary catheterization channel length. After the front-segment urine is emptied, the middle and rear-segment urine is retained as a sample; through the hierarchical design of flushing the urinary catheterization channel and the sub-channels by emptying the front-segment urine, the problem of bacterial interference in the planned urination mode is solved.

[0103] In an embodiment of the present application, during the process of bladder function recovery, the functional training sub-module further includes setting a biochemical sensor in the anti-blocking channel to detect key biochemical indicators in urine in real time, including the pH value of urine, red blood cell concentration, protein concentration, and inflammatory factors; fusing and analyzing the collected biochemical indicators with bladder pressure, urine flow rate, and color data to establish a health assessment model; using the health assessment model to determine in real time whether there is a situation where the current stimulation causes abnormal bladder training; when the current stimulation causes abnormal bladder training, automatically adjusting the working parameters of the auxiliary device, including stimulation intensity, duration, and mode, and sending out a warning signal to prompt medical staff to intervene and adjust; at the same time, generating personalized bladder function recovery suggestions according to the dynamic changes of biochemical indicators to guide the adjustment of the subsequent training plan.

[0104] In this embodiment, by introducing biochemical index monitoring to comprehensively monitor the bladder state, it is no longer limited to single mechanical data, which can more comprehensively reflect the health status of the bladder tissue, timely detect potential inflammation or metabolic abnormalities, and thus prevent secondary injuries that may be caused by the stimulation training method; the intelligent analysis after data fusion can achieve real-time and dynamic feedback regulation, ensuring that the auxiliary device can effectively activate the detrusor muscle and avoid tissue fatigue or injury caused by excessive stimulation, realizing personalized rehabilitation training in the true sense; at the same time, through real-time monitoring and comprehensive data analysis, the system can detect abnormal states earlier, timely adjust the treatment strategy, and thus significantly improve the overall bladder function recovery effect and patient safety.

[0105] In an embodiment of the present application, as shown in Figure 8 it also includes a personalized management module for obtaining the normal urine flow rate standard and urine color standard of the current patient. Specifically, by obtaining the medical data of the current patient, the medical data includes patient physical sign data and the diseases suffered, and the current urine flow rate standard and color standard of the current patient are obtained through the medical data.

[0106] It should be noted that the flow rate and color of urine are not only affected by an individual's physiological state, but also significantly influenced by the type of disease the patient has, the treatment stage, and the use of medications. For normal healthy individuals, the color of urine is usually light yellow or golden yellow, and the flow rate is within a certain standard range (for example, the daily urine volume of an adult is 800 milliliters to 2000 milliliters, and the flow rate is between 30 milliliters and 100 milliliters per hour). However, for patients with specific diseases (such as those who have undergone bladder surgery, neurogenic bladder patients, or patients receiving certain medications), the changes in the color and flow rate of their urine may be different from the normal standards. For example, in patients who have undergone bladder surgery, the bladder has not fully recovered its normal function, resulting in a decrease in urine output (oliguria), or the urine may contain blood (hematuria), making the urine appear pink or red. However, these changes are normal or acceptable for the current stage of the patient's condition; after subsequent treatment and recovery, it gradually approaches the normal urine flow rate standard and color standard.

[0107] In an embodiment of the present application, the medical data further includes prescription data. The types of medications and the volume of fluid input are obtained according to the prescription data. The urine flow rate standard and the urine color standard are adjusted based on the changes in urine color and urine volume caused by using these types of medications. At the same time, the urine flow rate standard is adjusted according to the volume of fluid input.

[0108] In this embodiment, the medical data of the patient is obtained. According to the disease the patient has, the treatment stage, and the medications used, personalized urine flow rate standards and color standards are specified, effectively improving the accuracy of alarms and reducing the workload of medical staff caused by false alarms and disturbing the patient's rest. Further, the prescription data of the patient is obtained, including the types and volumes of fluids input by the patient every day. The more fluids are input, the corresponding urine volume will increase. Otherwise, the patient will have adverse reactions such as edema. When there is a diuretic component in the medication or it causes a change in urine color, the urine volume will increase or the urine color will change. Therefore, the urine color standard and the urine flow rate standard are adjusted according to the types and volumes of fluids input by the patient every day.

[0109] In an embodiment of the present application, the personalized management module further includes obtaining the patient's rest time and medication time. The sampling times for nocturia, morning urine, and routine urine are obtained according to the rest time, and the sampling times for routine urine and urine after medication are obtained according to the medication time. The switch corresponding to the sub-channel is turned on at the sampling time, and the sub-channel into which the urine enters is recorded. After the sampling is completed, the switch corresponding to the sub-channel is turned off.

[0110] In this embodiment, the work and rest time and medication time of the patient are obtained. Specifically, the patient and medical staff can input the work and rest type and time, as well as the medication time, into the system. Alternatively, an image acquisition device can automatically identify the patient's daily sleep, waking up, and medication. When corresponding samples are needed, including nocturia, morning urine, routine urine, and urine after medication, according to the patient's work and rest time and medication time, the switch corresponding to the sub-channel is selected to be opened at the corresponding time, and then closed after sampling, waiting for the medical staff to retrieve. Combining the setting of the sub-channel, it is more convenient to obtain the corresponding type of sample urine.

[0111] In the second aspect of the present application, as shown in Figure 9 Figure, a multi-channel liquid output monitoring device capable of identifying colors is further provided, including:

[0112] A channel assembly, including a urinary catheterization channel, multiple sub-channels, and an anti-blocking channel. One end of the urinary catheterization channel enters the bladder through the urethra, and the other end is connected to the multiple sub-channels and an anti-blocking channel. A switch is set for each sub-channel, and the anti-blocking channel remains connected to the urine storage bag. Urine enters the sub-channel and the anti-blocking channel with the switch opened after passing through the urinary catheterization channel;

[0113] A sensor assembly, including multiple flow sensors and multiple optical sensors. The flow sensors measure the liquid volume of urine in the urinary catheterization channel and each sub-channel to obtain flow data; the optical sensors measure the color of urine in each sub-channel to obtain color data;

[0114] A computer assembly analyzes and organizes the flow data and the color data to generate a urine discharge report. At the same time, it obtains the normal urine flow standard and urine color standard, and compares them with the urine discharge report to determine whether there are abnormalities in the flow data and the color data;

[0115] A communication and alarm assembly, including a communication device and an alarm device. The communication device receives an abnormal signal and controls the alarm device to issue an alarm; at the same time, the communication device sends the urine discharge report and the comparison result to the doctor's terminal.
