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: 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: A channel drainage module is used to collect urine discharged through the urinary catheterization channel, one end of which enters the bladder through the urethra and the other end is connected to the urine storage bag; The data comparison module monitors the urine flow rate of the catheterization channel through a flow sensor and the urine color of the catheterization channel through an optical sensor; and compares the urine flow rate and the standard color range with normal urine; 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; 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.

[0006] 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.

[0007] 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; 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 action; The pressure monitoring module also includes a feedback submodule, which dynamically displays the real-time data of the pressure data and the flow data to medical staff and / or patients through a visualization device, sets the pressure data and the flow data as associated data, and presets the pressure data of different data segments to correspond to the flow data of different data segments. When an abnormality occurs, the medical staff and / or patients are reminded to pay attention and take action.

[0008] In one embodiment of the present application, the feedback submodule also includes a functional training submodule, which stimulates the bladder area through an auxiliary device to induce reflex contraction of the detrusor muscle at a preset time and when the preset value of the pressure data is reached, and simultaneously records the patient's bladder capacity, pressure changes and urine emptying data, generates personalized bladder function recovery suggestions, and adjusts the preset time and the preset value of the pressure data accordingly.

[0009] In one embodiment of the present application, the sample collection module further includes a segmented discharge submodule, which is configured to control the segmented collection of urine during the planned urination process of the functional training submodule, including: The front discharge unit is configured to open the second switches of all the sub-channels when urination is started, and simultaneously open the first switches of the sub-channels one by one, and only one first switch is opened at the same time; A flushing trigger unit, configured to generate a flushing completion signal after the discharge of the first urine segment is completed, wherein the amount of the first urine segment is determined according to the channel data and the length of the urinary catheterization channel; The urine collection unit responds to the flushing completion signal and closes the second switch to allow the middle and rear urine to enter the branch channel set by the sample collection module.

[0010] In one embodiment of the present application, during the bladder function recovery process, the functional training 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 the collected biochemical indicators with bladder pressure, urine flow and color data for analysis to establish a health assessment model; using the health assessment model to determine in real time whether the bladder tissue has a current stimulus that causes abnormal bladder training; when the current stimulus causes abnormal bladder training, automatically adjusting the working parameters of the auxiliary equipment, including stimulation intensity, duration and mode, and issuing a warning signal to prompt medical staff to intervene and make adjustments; at the same time, based on the dynamic changes of biochemical indicators, generating personalized bladder function recovery suggestions to guide the adjustment of subsequent training plans.

[0011] In one embodiment of the present application, a personalized management module is also included, which is used to obtain the normal urine flow standard and urine color standard of the current patient, specifically by obtaining the medical data of the current patient, the medical data including the patient's vital signs data and the disease suffered by the patient, and the current urine flow standard and color standard of the current patient are obtained through the medical data.

[0012] In one embodiment of the present application, the medical data also includes prescription data, and the type of medicine and the amount of liquid input are obtained based on the prescription data. The urine flow standard and the urine color standard are adjusted according to the changes in urine color and urine volume caused by the use of the type of medicine, and the urine flow standard is adjusted according to the liquid input amount.

[0013] In one embodiment of the present application, the personalized management module also includes obtaining the patient's work and rest schedule and medication time, obtaining the sampling time of nocturnal urine, morning urine, and regular urine according to the work and rest schedule, obtaining the sampling time of regular urine and post-medication urine according to the medication time, turning on the switch corresponding to the sub-channel at the sampling time, and recording the sub-channel that urine enters, and closing the switch corresponding to the sub-channel after sampling is completed.

[0014] In a second aspect of the present application, a color-recognizable multi-channel liquid output monitoring device is also provided, comprising: A channel assembly, comprising a urinary catheter channel, one end of which enters the bladder through the urethra and the other end of which is connected to a urine storage bag; A sensor assembly, which monitors the urine flow rate of the catheterization channel through a flow sensor and monitors the urine color of the catheterization channel through an optical sensor; and compares the urine color with a standard flow rate and a standard color range of normal urine; Communication alarm component, when the monitored urine flow and / or urine color exceeds the normal range, an alarm is sounded through the alarm device to remind medical staff and / or patients to pay attention and take measures; at the same time, the urine discharge report and comparison results are sent to the doctor; The sample collection component has a plurality of sub-channels arranged 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.

[0015] This application has the following beneficial effects: 1. The flow sensor collects the flow data in the channel, and the optical sensor collects the color data in the channel. The system automatically compares the data with the urine flow standard and the urine color standard in real time. When it is identified 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 action to avoid further development of the abnormal situation and take action as soon as possible; through the multi-channel setting, it is avoided that the single-channel catheter directly collects urine at different times into the urine storage bag, which makes it difficult to observe and sample urine at the same time or different time periods. Specifically, according to needs, urine at the same time can be allowed to enter multiple branch channels respectively to obtain multiple identical samples, which is convenient for sampling and testing; samples can also be kept separately in the branch channels without mixing with normal urine at other times, thereby improving sample representativeness and the accuracy of test results, providing reliable technical support for patient care and disease diagnosis; in the prior art, although time-divided storage is achieved, the number and storage capacity of branch channels are limited, and the initial urine discharge of intubated patients is continuous, and the time when abnormal urine appears is also uncertain. Therefore, in order not to miss abnormal urine with testing value, a large number of branch channels are required to achieve full coverage of the collection time through the branch channels, but such a setting makes the entire device bulky and increases the cost. ; or medical staff are required to frequently process 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 the preset time, even if 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; and the present application sets a plurality of sub-channels on the urinary catheterization channel through the setting of the sample collection module. Different from the prior art of storing urine in different time periods through multiple channels, the sub-channels of the present application are combined with an alarm processing module. When the patient's urine is abnormal, the sub-channels are opened for sample collection. This design achieves targeted storage of abnormal urine and can also effectively reduce the number of sub-channels; 2. A mechanical timing device and / or a signal control device are provided for the first switch and the second switch of the sub-channel, and the opening and closing of different sub-channel switches are pre-set and / or remotely controlled, so that urine enters the sub-channel opened by the first switch at a preset time, and urine is discharged from the sub-channel opened by the second switch at a preset time; by setting different switch logics, different types of urine samples are obtained in the sub-channels, for example, multiple sub-channels are opened at the same time, and the urine samples in the multiple sub-channels are the same; only one sub-channel is opened, and it is closed after it is full, and the next sub-channel is opened, and the change in the patient's urine color can be intuitively seen according to the order of the sub-channels; the present application supplements the conventional collection function on the basis of opening the sub-channel after identifying the abnormality, because the urine discharge of patients who are intubated for urination in the early stage is continuous and slow, so The amount of urine in the urinary channel is not much, so it is relatively difficult to identify the color change. Therefore, the present application concentrates the urine in the sub-channels and compares the urine in the adjacent sub-channels to identify the change in urine color in a similar period of time. If an abnormality occurs, the urine is stored; if there is no abnormality, the urine is returned to the urinary catheterization channel through the second switch and enters the urine storage bag; at the same time, the flow of the urinary catheterization channel collected by the flow sensor can be compared with the sum of the flows of the sub-channels turned on by the switch. If the sum of the flows of the sub-channels is less than the flow of the urinary catheterization channel, an inspection is performed to avoid leakage or blockage of the sub-channels; further, by pre-setting and / or remotely controlling the opening and closing of the switch, it is possible to collect urine samples of patients at specific times, such as morning urine and night urine, without increasing the workload of medical staff.

[0016] 3. By setting a pressure sensor at one end of the catheterization channel entering the bladder, the pressure data in the patient's bladder can be monitored. First, when the pressure data is identified to be abnormal, the medical staff and / or the patient are notified to pay attention and take measures to avoid the bladder pressure being in an abnormal state for a long time; further, the real-time data of the pressure data and the flow data 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 flow data. 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 any abnormality.

[0017] 4. Patients undergo bladder training in the later stage of catheterization to gradually restore bladder capacity, urination reflex and autonomous urination function. At the preset time and when the preset value of the pressure data is reached, the bladder area is stimulated by auxiliary equipment to induce reflex contraction of the detrusor muscle, and the patient's bladder capacity, pressure changes and urine emptying data are recorded at the same time to generate personalized bladder function recovery suggestions, and the preset time and preset value of the pressure data are adjusted accordingly; the autonomous urination function of the bladder is gradually realized; the specific technical solutions include: Early intervention of bladder function: In the later stage of catheterization, evaluate the patient's bladder function. When the patient's bladder function has not been completely lost, use a monitoring and training system to gradually enhance the bladder function and reduce the risk of urination disorders after catheter removal.

[0018] Provide personalized training guidance: Design a personalized bladder training plan based on the patient's bladder filling capacity, urination time and urine flow characteristics to gradually improve the detrusor contraction ability and sphincter control ability.

[0019] Promote nerve reflex recovery: through physical stimulation, including electrical stimulation, or behavioral intervention, including urination guidance and feedback, reactivate the urination reflex arc and improve the nerve's ability to control the bladder. The patient can view his own bladder pressure through the visualization device, and when the predetermined pressure is reached, urination is induced; Through advance training, urinary retention or incontinence caused by bladder insufficiency can be reduced, avoiding the need for re-catheterization; it can help patients resume autonomous urination as soon as possible, reduce the psychological and physiological burden of long-term dependence on a catheter, and effectively improve the patient's quality of life; at the same time, urination problems after catheter removal may increase the risk of urinary tract infection, and bladder training can help reduce the risk of these complications.

[0020] 5. Considering that the urination of intubated patients during the later training is planned urination, which is different from the continuous slow urination when the catheter is just intubated, planned urination will store urine for a period of time and then discharge it in a centralized manner, so that the patient's bladder can achieve functional training and recovery before the catheter is removed. 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 centralized urination, these bacteria may be brought into the sample, making the number of bacteria in the sample different from the bacteria in the patient's actual urine, resulting in inaccurate data. Therefore, this application abandons the front section of urine during centralized urination and opens the full The central controller switches on all the sub-channels to flush the urinary catheter through the front section of urine; specifically, when urination starts, the central controller opens the second switches of all the sub-channels synchronously, and opens the first switches one by one to form a flushing passage. The first switch adopts a sequential pulse opening mode (for example, switching a sub-channel every 200ms) to ensure that the flushing liquid flow covers the inner walls of all sub-channels; after the discharge of the front section of urine is completed, that is, after the flushing of the catheterization channel and the sub-channels is completed, a flushing completion signal is generated. The amount of front section urine is determined according to the sub-channel data and the length of the catheterization channel. Specifically, the front section urine amount determination model is:

[0021] Among them, V i is the volume of the ith sub-channel (preset value), k is the tube wall adhesion coefficient (default 0.15), L is the real-time catheterization channel length, and the middle and rear urine samples are retained after the front urine is emptied. The hierarchical design of the catheterization channel and sub-channels for flushing the front urine can solve the problem of bacterial interference in the planned urination mode.

[0022] 6. By introducing biochemical indicators to monitor the bladder status comprehensively, it is no longer limited to a single mechanical data. It can more comprehensively reflect the health status of bladder tissue and timely detect potential inflammation or metabolic abnormalities, thereby preventing secondary injuries that may be caused by stimulation training methods; intelligent analysis after data fusion can realize real-time and dynamic feedback regulation to ensure that the auxiliary equipment can effectively activate the detrusor muscle and avoid tissue fatigue or damage due to excessive stimulation, thus realizing truly personalized rehabilitation training; at the same time, through real-time monitoring and comprehensive data analysis, the system can detect abnormal conditions earlier and adjust the treatment strategy in time, thereby significantly improving the overall bladder function recovery effect and patient safety.

[0023] 7. Obtain the patient's medical data, and specify the corresponding personalized urine flow rate standard and color standard according to the patient's disease, treatment stage and medication used, so as to effectively improve the accuracy of the alarm and reduce false alarms that lead to increased workload for medical staff and disturbing the patient's rest; further, obtain the patient's prescription data, including the type and amount of fluid the patient inputs every day. The more fluid the patient inputs, the higher the urine will be. Otherwise, the patient will have adverse reactions such as edema, and when there are diuretic components in the drug or the urine color changes, the urine volume will increase or the urine will change color; therefore, the urine color standard and the urine flow standard are adjusted accordingly according to the type and amount of fluid the patient inputs every day.

[0024] 8. Obtain the patient's work and rest schedule and medication time. Specifically, the patient and medical staff can input the work and rest type and time, as well as the medication time into the system. The image acquisition device can also be used to automatically identify the patient's daily sleep, waking up, and medication. When corresponding samples are needed, including nocturnal urine, morning urine, regular urine, and urine after medication, according to the patient's work and rest schedule and medication time, the corresponding time is selected to open the switch of the corresponding sub-channel. After sampling is completed, it is closed and waits for medical staff to use it. Combined with the setting of the sub-channel, the corresponding type of sample urine can be obtained more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also 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 (WIreless-FIdelity, WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0037] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the electronic device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0038] like Figure 1As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module and a data storage module.

[0039] exist Figure 1 In 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 can be set in the electronic device, and the electronic device calls a color-recognizable multi-channel liquid output monitoring device stored in the data storage module in the memory 1005 through the processor 1001, and executes the liquid output monitoring system of the present application.

[0040] Based on the aforementioned hardware operating environment and system architecture, in the first aspect of the present application, refer to Figure 2 , Figure 3 and Figure 4 As shown, a multi-channel liquid output monitoring device capable of identifying colors is provided, including a monitoring system, wherein the monitoring system includes: A channel drainage module is used to collect urine discharged through the urinary catheterization channel, one end of which enters the bladder through the urethra and the other end is connected to the urine storage bag; The data comparison module monitors the urine flow rate of the catheterization channel through a flow sensor and the urine color of the catheterization channel through an optical sensor; and compares the urine flow rate and the standard color range with normal urine; It should be noted that the flow sensor collects the flow in different pipes to obtain the patient's current real-time flow, and the stage flow in different time periods can be further obtained based on the real-time flow; similarly, the optical sensor collects the color data in the channel to obtain the patient's current urine color, and further compares the urine color at different times to obtain the urine color change; It should be noted that the urine output of a normal adult is usually 800 ml to 2,000 ml / day. For patients with long-term catheterization, the normal hourly urine flow rate should be 30 ml / hour to 100 ml / hour. If the urine flow rate is less than 30 ml / hour, the patient may have difficulty in urinary discharge; It should be noted that the normal standard color of urine is light yellow or golden yellow, indicating that the concentration of uroflavin (the main pigment in urine) in the urine is moderate, and the patient usually has normal water intake and no obvious pathological problems; 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; 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; 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.

[0041] 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. In this embodiment, the flow data in the channel is collected by the flow sensor, and the optical sensor collects the color data in the channel. The system automatically compares the data with the urine flow standard and the urine color standard in real time. 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 action to avoid further development of the abnormal situation and to deal with it as soon as possible. Through the multi-channel setting, it is avoided that a single-channel catheter directly collects urine at different times into a urine storage bag, which makes it difficult to observe, sample, and perform other operations on urine at the same time or different time periods. Specifically, according to needs, urine at the same time can be allowed to enter multiple branch channels respectively to obtain multiple identical samples, which is convenient for sampling and testing; samples can also be kept separately in the branch channels without mixing with normal urine at other times, thereby improving sample representativeness and the accuracy of test results, providing reliable technical support for patient care and disease diagnosis; in the prior art, although time-divided storage is achieved, the number and storage capacity of branch channels are limited, and the initial urine discharge of intubated patients is continuous, and the time when abnormal urine appears is also uncertain. Therefore, in order not to miss abnormal urine with testing value, a large number of branch channels are required to achieve full coverage of the collection time through the branch channels, but such a setting makes the entire device bulky and increases the cost. ; or medical staff are required to frequently process 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 the preset time, even if 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; and the present application sets a plurality of sub-channels on the urinary catheterization channel through the setting of the sample collection module. Different from the prior art of storing urine in different time periods through multiple channels, the sub-channels of the present application are combined with an alarm processing module. When the patient's urine is abnormal, the sub-channels are opened for sample collection. This design achieves targeted storage of abnormal urine and can also effectively reduce the number of sub-channels; Furthermore, according to the abnormal conditions of the flow data and the color data of the urine, graded alarms are issued, and medical staff take corresponding treatment methods; for example, abnormal urine volume includes abnormal conditions of decreased urine volume, oliguria: If the daily urine volume of the 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 the intubated patient does not urinate at all (urine volume is close to 0 ml / hour), it may indicate acute renal failure, urinary tract obstruction and other acute pathological problems, which require emergency treatment. Abnormal conditions 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.

[0042] Abnormal urine color includes dark yellow or amber (mild dehydration): If the urine is dark, amber or dark yellow, it usually indicates that the patient may be in a state of mild dehydration or insufficient water intake. The fluid balance of intubated patients requires special attention, because long-term catheterization may cause fluid imbalance. Clear or almost colorless (overhydration): If the urine is clear or almost colorless, it may mean that the patient has taken in too much fluid, resulting in dilution of the urine. Long-term overhydration may affect the electrolyte balance in the body, especially in patients with weak kidney function. Pink or red (hematuria): If the urine of intubated patients is pink, red or tea-colored, it usually indicates that there is blood in the urine, which may be caused by urinary tract injury, infection or improper operation of the catheter. 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 make the urine appear orange or yellow. Bilirubinuria (yellow urine) usually indicates abnormalities of the hepatobiliary system, such as hepatitis, biliary obstruction, etc. If this happens in an intubated patient, the possibility of drugs or hepatobiliary diseases should be considered. Green or blue (drugs or infection): The green or blue urine of intubated patients is usually caused by certain drugs (such as meclorol, painkillers, etc.) or infections (such as Pseudomonas aeruginosa infection). If there is no history of drug use, further examination is required for urinary tract infection. Milky white (chyluria): Chyluria is usually caused by lymph fluid entering the urine, which may be caused by lymphatic vessel damage or infection (such as lymphadenopathy, lymphoma, etc.). If an intubated patient has milky urine, further diagnosis is usually required.

[0043] Medical staff can take corresponding measures based on the specific abnormal conditions identified by the system and the patient's medical records, effectively saving time.

[0044] In one embodiment of the present application, see Figure 5 As shown, 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.

[0045] 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-channel, and the opening and closing of different sub-channel switches are pre-set and / or remotely controlled, so that urine enters the sub-channel opened by the first switch at a preset time, and urine is discharged from the sub-channel opened by the second switch at a preset time; by setting different switch logics, different types of urine samples are obtained in the sub-channels, for example, multiple sub-channels are opened at the same time, and the urine samples in the multiple sub-channels are the same; only one sub-channel is opened, closed after it is full, and the next sub-channel is opened, so that urine can be discharged from the sub-channel opened by the second switch at a preset time; According to the arrangement of the sub-channels, the change of the patient's urine color can be intuitively seen; the present application supplements the conventional collection function on the basis of opening the sub-channels after identifying the abnormality, because the urine discharge of the patients who are intubated for urination in the early stage is continuous and slow, so the amount of urine in the urinary catheter channel is not much, so it is relatively difficult to identify the color change, so the present application can identify the change of urine color in a similar time by concentrating the urine in the sub-channels and comparing the urine in the adjacent sub-channels, if there is an abnormality, the urine is stored; if there is no abnormality, the urine is returned to the urinary catheter 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 flows of the branch channels when the switch is turned on. If the sum of the flows of the branch channels is less than the flow rate of the catheterization channel, an inspection can be performed to avoid leakage or blockage of the branch channels. Furthermore, by presetting and / or remotely controlling the opening and closing of the switch, it is possible to collect urine samples of patients at specific times, such as morning urine and nocturnal urine, without increasing the workload of medical staff.

[0046] In one embodiment of the present application, see Figure 6 As shown, a pressure monitoring module is also included, wherein a pressure sensor is arranged at one end of the urinary catheterization channel inserted into the bladder, and the pressure sensor is used to measure the pressure data in the patient's bladder; 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 action; The pressure monitoring module also includes a feedback submodule, which dynamically displays the real-time data of the pressure data and the flow data to medical staff and / or patients through a visualization device, sets the pressure data and the flow data as associated data, and presets the pressure data of different data segments to correspond to the flow data of different data segments. When an abnormality occurs, the medical staff and / or patients are reminded to pay attention and take action.

[0047] It should be noted that patients with catheters are usually unable to urinate on their own, so the urination process is usually achieved through an externally inserted catheter. In the absence of other factors such as urethral obstruction, urination is determined by bladder pressure and urethral patency rather than active control. The urination process is mainly driven by bladder filling and pressure changes. There is a positive relationship between the pressure in the bladder and the urine flow in the catheter, and increased bladder pressure usually leads to an increase in urine flow. Therefore, when bladder pressure changes and urine flow does not change accordingly, it is necessary to consider whether there is something wrong with the patient or the catheter. Factors such as urethral resistance or catheter obstruction can affect urine flow. Close monitoring of bladder pressure and urine flow is crucial to the prevention and treatment of bladder dysfunction, urinary tract obstruction and other problems. In this embodiment, by setting a pressure sensor at one end of the catheterization channel entering the bladder, the pressure data in the patient's bladder is monitored. First, when the pressure data is identified to be abnormal, the medical staff and / or the patient are notified to pay attention and take measures to avoid the bladder pressure being in an abnormal state for a long time; further, the real-time data of the pressure data and the flow data 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 flow data. When there is no corresponding change between the two, an alarm notification is issued to remind the medical staff and / or the patient to pay attention and check whether there is any abnormality.

[0048] In one embodiment of the present application, see Figure 7 As shown, the feedback submodule also includes a functional training submodule, which stimulates the bladder area through auxiliary equipment to induce reflex contraction of the detrusor muscle at a preset time and when the preset value of the pressure data is reached, and simultaneously records the patient's bladder capacity, pressure changes and urine emptying data, generates personalized bladder function recovery suggestions, and correspondingly adjusts the preset time and the preset value of the pressure data.

[0049] It should be noted that long-term catheterization may lead to functional degeneration, including: Bladder deconditioning: Long-term catheterization may cause the bladder to remain empty, and the normal contraction function of the bladder muscle (detrusor muscle) gradually weakens or is lost, resulting in urine retention or difficulty urinating after the catheter is removed.

[0050] Weakened sphincter function: During catheterization, the urethral sphincter may become weak or lose the ability to control urine outflow due to lack of active control, making urinary incontinence more likely to occur after the catheter is removed.

[0051] Changes in the urination reflex pathway: The bladder urination reflex usually relies on complex neural regulation, including the participation of the spinal cord and the cerebral cortex. Catheterization may cause the reflex arc to be inactivated, and after the catheter is removed, the patient may not be able to sense the bladder filling or actively control urination.

[0052] Common urination problems after catheter removal: Dysuria or urinary retention: The patient is unable to start urination after the bladder is full and requires manual compression or reinsertion of the catheter.

[0053] Urinary incontinence: Particularly in patients with an overactive bladder, involuntary leakage of urine may occur because the urethral sphincter has not regained control.

[0054] Weak urination: Urine flow is low and urination time is long due to detrusor muscle weakness.

[0055] In this embodiment, in order to avoid the above problems, the patient undergoes bladder training in the later stage of catheterization to gradually restore the bladder capacity, urination reflex and autonomous urination function. At the preset time and when the preset value of the pressure data is reached, the bladder area is stimulated by an auxiliary device to induce reflex contraction of the detrusor muscle, and the patient's bladder capacity, pressure changes and urine emptying data are recorded at the same time, and personalized bladder function recovery suggestions are generated, and the preset time and the preset value of the pressure data are adjusted accordingly; the autonomous urination function of the bladder is gradually realized; the specific technical solutions include: Early intervention of bladder function: In the later stage of catheterization, evaluate the patient's bladder function. When the patient's bladder function has not been completely lost, use a monitoring and training system to gradually enhance the bladder function and reduce the risk of urination disorders after catheter removal.

[0056] Provide personalized training guidance: Design a personalized bladder training plan based on the patient's bladder filling capacity, urination time and urine flow characteristics to gradually improve the detrusor contraction ability and sphincter control ability.

[0057] Promote nerve reflex recovery: through physical stimulation, including electrical stimulation, or behavioral intervention, including urination guidance and feedback, reactivate the urination reflex arc and improve the nerve's ability to control the bladder. The patient can view his own bladder pressure through the visualization device, and when the predetermined pressure is reached, urination is induced; Through advance training, urinary retention or incontinence caused by bladder insufficiency can be reduced, avoiding the need for re-catheterization; it can help patients resume autonomous urination as soon as possible, reduce the psychological and physiological burden of long-term dependence on a catheter, and effectively improve the patient's quality of life; at the same time, urination problems after catheter removal may increase the risk of urinary tract infection, and bladder training can help reduce the risk of these complications.

[0058] In one embodiment of the present application, the sample collection module further includes a segmented discharge submodule, which is configured to control the segmented collection of urine during the planned urination process of the functional training submodule, including: The front discharge unit is configured to open the second switches of all the sub-channels when urination is started, and simultaneously open the first switches of the sub-channels one by one, and only one first switch is opened at the same time; A flushing trigger unit, configured to generate a flushing completion signal after the discharge of the first urine segment is completed, wherein the amount of the first urine segment is determined according to the channel data and the length of the urinary catheterization channel; The urine collection unit responds to the flushing completion signal and closes the second switch to allow the middle and rear urine to enter the branch channel set by the sample collection module.

[0059] In this embodiment, considering that the urination of the intubated patient during the later training is planned urination, which is different from the continuous slow urination when the catheter is just intubated, the planned urination will store the urine for a period of time and then discharge it in a concentrated manner, so that the patient's bladder can achieve functional training and recovery before the catheter is removed. 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, making the number of bacteria in the sample different from the bacteria in the patient's actual urine, resulting in inaccurate data. Therefore, during concentrated urination, the present application discards the front part of the urine, and at the same time Turn on all switches and flush the urinary catheter through the front section of urine; specifically, when urination starts, the central controller synchronously turns on the second switches of all sub-channels, and turns on the first switches one by one to form a flushing path. The first switch adopts a sequential pulse opening mode (for example, switching a sub-channel every 200ms) to ensure that the flushing liquid flow covers the inner walls of all sub-channels; after the discharge of the front section of urine is completed, that is, after the flushing of the catheterization channel and the sub-channels is completed, a flushing completion signal is generated. The amount of front section urine is determined according to the sub-channel data and the length of the catheterization channel. Specifically, the front section urine amount determination model is:

[0060] Among them, V i is the volume of the ith sub-channel (preset value), k is the tube wall adhesion coefficient (default 0.15), L is the real-time catheterization channel length, and the middle and rear urine samples are retained after the front urine is emptied. The hierarchical design of the catheterization channel and sub-channels for flushing the front urine can solve the problem of bacterial interference in the planned urination mode.

[0061] In one embodiment of the present application, during the bladder function recovery process, the functional training 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 the collected biochemical indicators with bladder pressure, urine flow and color data for analysis to establish a health assessment model; using the health assessment model to determine in real time whether the bladder tissue has a current stimulus that causes abnormal bladder training; when the current stimulus causes abnormal bladder training, automatically adjusting the working parameters of the auxiliary equipment, including stimulation intensity, duration and mode, and issuing a warning signal to prompt medical staff to intervene and make adjustments; at the same time, based on the dynamic changes of biochemical indicators, generating personalized bladder function recovery suggestions to guide the adjustment of subsequent training plans.

[0062] In this embodiment, by introducing biochemical indicators to monitor the bladder status comprehensively, it is no longer limited to a single mechanical data, and can more comprehensively reflect the health status of the bladder tissue, timely detect potential inflammation or metabolic abnormalities, thereby preventing secondary injuries that may be caused by stimulation training methods; intelligent analysis after data fusion can achieve real-time, dynamic feedback regulation to ensure that the auxiliary equipment can effectively activate the detrusor muscle and avoid tissue fatigue or damage due to excessive stimulation, thereby achieving truly personalized rehabilitation training; at the same time, through real-time monitoring and comprehensive data analysis, the system can detect abnormal conditions earlier and adjust the treatment strategy in time, thereby significantly improving the overall bladder function recovery effect and patient safety.

[0063] In one embodiment of the present application, see Figure 8 As shown, it also includes a personalized management module, which is used to obtain the normal urine flow standard and urine color standard of the current patient, specifically by obtaining the medical data of the current patient, the medical data including the patient's physical sign data and the disease suffered by the patient, and the current urine flow standard and color standard of the current patient are obtained through the medical data.

[0064] It should be noted that the flow and color of urine are not only affected by the individual's physiological state, but also significantly affected by the type of disease the patient suffers from, the stage of treatment, and the use of drugs. For normal healthy people, 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 adults is 800 ml to 2000 ml, and the flow rate is between 30 ml and 100 ml per hour). However, for patients with specific diseases (such as patients after bladder surgery, patients with neurogenic bladder, or patients receiving certain medications), the color and flow of their urine may change from the standards of normal people. For example, for patients after bladder surgery, the bladder has not fully restored its normal function, resulting in reduced urine discharge (oliguria), or the urine may contain blood (hematuria), making the urine pink or red, but these changes are normal or acceptable for the current stage of the patient's condition; after subsequent treatment and recovery, it gradually approaches the flow standard and color standard of normal urine; In one embodiment of the present application, the medical data also includes prescription data, and the type of medicine and the amount of liquid input are obtained based on the prescription data. The urine flow standard and the urine color standard are adjusted according to the changes in urine color and urine volume caused by the use of the type of medicine, and the urine flow standard is adjusted according to the liquid input amount.

[0065] In this embodiment, the patient's medical data is obtained, and corresponding personalized urine flow standards and color standards are specified according to the patient's disease, treatment stage and medications used, so as to effectively improve the accuracy of alarms and reduce false alarms that lead to increased workload for medical staff and disturbing patients' rest; further, the patient's prescription data is obtained, including the type and amount of fluid the patient inputs every day. The more fluid the patient inputs, the higher the urine will be. Otherwise, the patient will have adverse reactions such as edema, and when there are diuretic components in the drug or the urine color changes, the urine volume will increase or the urine will change color; therefore, the urine color standard and the urine flow standard are adjusted accordingly according to the type and amount of fluid the patient inputs every day.

[0066] In one embodiment of the present application, the personalized management module also includes obtaining the patient's work and rest schedule and medication time, obtaining the sampling time of nocturnal urine, morning urine, and regular urine according to the work and rest schedule, obtaining the sampling time of regular urine and post-medication urine according to the medication time, turning on the switch corresponding to the sub-channel at the sampling time, and recording the sub-channel that urine enters, and closing the switch corresponding to the sub-channel after sampling is completed.

[0067] In this embodiment, the patient's work and rest schedule and medication time 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, or the image acquisition device can be used to automatically identify the patient's daily sleep, waking up, and medication. When corresponding samples are needed, including nocturnal urine, morning urine, regular urine and urine after medication, according to the patient's work and rest schedule and medication time, the switch of the corresponding sub-channel is turned on at the corresponding time, and the switch is closed after sampling is completed, waiting for medical staff to use it. Combined with the setting of the sub-channel, the corresponding type of sample urine can be obtained more conveniently.

[0068] In the second aspect of this application, see Fig. 9 As shown, a multi-channel liquid output monitoring device capable of identifying colors is also provided, comprising: A channel assembly includes a urinary catheterization channel, a plurality of branch 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 plurality of branch channels and the anti-blocking channel. A switch is provided for each branch channel. The anti-blocking channel maintains communication with the urine storage bag. Urine passes through the urinary catheterization channel and enters the branch channels and the anti-blocking channel with the switches turned on. A sensor assembly, comprising a plurality of flow sensors and a plurality of optical sensors, wherein the flow sensors measure the amount of urine in the urinary catheterization channel and each branch channel to obtain flow data; and the optical sensors measure the color of urine in each branch channel to obtain color data; A computer component analyzes and organizes the flow data and the color data to generate a urine discharge report, and simultaneously obtains a normal urine flow rate standard and a urine color standard, and compares them with the urine discharge report to determine whether the flow data and the color data are abnormal; The communication alarm component includes a communication device and an alarm device. The communication device receives an abnormal signal and controls the alarm device to sound an alarm. At the same time, the communication device sends the urine discharge report and comparison result to the doctor.
