[0002] During anesthesia and surgery, medical staff often need to monitor urine volume and color to assess renal function and the patient's condition. After urology surgery, complications may occur due to a variety of reasons, among which bladder spasm and postoperative catheter bleeding are common complications, which will have a certain impact on the patient's postoperative recovery.

[0003] At present, after the patient's urology surgery is completed, medical staff will continuously flush the bladder with saline to ensure that the blood in the bladder does not coagulate and avoid the formation of blood clots.

[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and cannot be understood as limiting the present invention.

[0047] It should be noted that although the functional modules are divided in the system diagram, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0049] According to a first aspect of the present invention, a urine volume measurement monitoring system is provided. Figure 1 In this embodiment, a urine volume metering monitoring system includes: a flushing component, a drainage component, a three-lumen catheter, an image acquisition module, a flow monitoring module, a monitoring line, a monitoring box, a control processing module and a hydraulic regulating valve. One end of the three-lumen catheter is respectively connected to the flushing component and the drainage component, and the other end of the three-lumen catheter extends into the human bladder through the human urethra. The hydraulic regulating valve is installed on the flushing component. The control processing module is arranged inside the monitoring box, the flow monitoring module is connected to the control processing module through the monitoring line, and the control processing module is respectively connected to the image acquisition module and the hydraulic regulating valve.

[0050] The flushing assembly is used to store the flushing liquid and introduce the flushing liquid into one end of the three-lumen urinary catheter. The flushing liquid enters the patient's bladder through the three-lumen urinary catheter to flush the patient's bladder. The drainage assembly is used to draw out the drainage liquid flowing out of the three-lumen urinary catheter and store the drainage liquid. The flow monitoring module is used to collect the amount of flushing liquid introduced into the three-lumen urinary catheter, and collect the amount of drainage liquid drawn out of the three-lumen urinary catheter. The flow monitoring module sends the collected amount of flushing liquid introduced and the amount of drainage liquid drawn out to the control processing module inside the monitoring box through the monitoring line. In other words, the liquid flow introduced into the human bladder and the liquid flow flowing out of the human bladder are collected, and the two collected liquid flows are sent to the control processing module. The image acquisition module is used to collect image information of the drainage liquid, and the collected image information is sent to the control processing module. The hydraulic control valve is used to adjust the flow rate of the flushing liquid introduced into the three-lumen urinary catheter.

[0051] The control processing module receives the amount of flushing fluid introduced and the amount of drainage fluid discharged collected in real time by the flow monitoring module, and performs calculation processing to obtain the patient's urine volume. The control processing module receives the drainage fluid image information collected by the image acquisition module, and performs image color recognition on the image information to identify the color of the drainage fluid and objectively determine the amount of blood in the drainage fluid. The control processing module controls the operation of the hydraulic regulating valve and adjusts the flow rate of the flushing fluid in the flushing component according to the obtained urine volume and the blood content in the drainage fluid. This is beneficial for patients to safely pass through the perioperative period, reduce postoperative complications, and bring a good experience to patients, so as to prevent the problem of subjective judgment of blood content and improper selection of flushing speed, which affects the effect of bladder flushing.

[0052] In this embodiment, the urine volume of the patient obtained by the control processing module is the difference between the drainage volume and the flushing volume.

[0053] The hydraulic regulating valve is operated according to predetermined requirements under the action of the sensor signal. The valve relies on a drive or automatic mechanism to make the opening and closing parts move up and down, slide, swing or rotate, thereby changing the size of its flow channel area to achieve its control function. In this embodiment, the hydraulic regulating valve is a micro electric hydraulic regulating valve. The control processing module sends a control signal to the hydraulic regulating valve according to the obtained urine volume and blood content in the drainage fluid. The hydraulic regulating valve is operated according to the predetermined requirements under the action of the control signal, so that the opening and closing parts slide, thereby changing the size of the flow channel area of ​​the drainage fluid in the drainage component, so as to achieve the change and regulation of the flow rate of the flushing fluid in the flushing component.

[0054] Reference Figure 1 In some embodiments of the present invention, a urine volume measurement monitoring system further includes: a temperature monitoring module, a pressure monitoring module and a heating module. The temperature monitoring module is arranged at the other end of the three-lumen urinary catheter and the flushing assembly, the pressure detection module is arranged at the other end of the three-lumen urinary catheter, the control processing module is connected to the temperature monitoring module and the pressure monitoring module through monitoring lines, the heating module is arranged on the flushing assembly, and the control processing module is connected to the heating module.

[0055] The temperature monitoring module is used to monitor the patient's bladder temperature and the liquid temperature of the flushing fluid, and sends the bladder temperature and liquid temperature to the control processing module through the monitoring line. The pressure monitoring module is used to monitor the pressure information of the bladder, and sends the pressure information to the control processing module through the monitoring line. The heating module is used to heat the flushing fluid in the flushing component. The control processing module receives the bladder temperature and liquid temperature sent by the temperature monitoring module and compares them. When the liquid temperature of the flushing fluid is lower than the patient's bladder temperature, the control processing module controls the operation of the heating module to heat the flushing fluid in the flushing component until the liquid temperature of the flushing fluid is consistent with the patient's bladder temperature. Since the temperature of the postoperative bladder flushing fluid is closely related to the occurrence of bladder spasm, the lower the temperature of the flushing fluid, the higher the incidence of bladder spasm. The use of flushing fluid close to the bladder temperature to flush the bladder has a lower incidence of bladder spasm, which is conducive to the patient's safe perioperative period, reduces postoperative complications, and brings a good experience to the patient.

[0056] In this embodiment, the types of the temperature monitoring module and the pressure monitoring module are not limited, and both the temperature monitoring module and the pressure monitoring module are arranged in front of one end of the three-lumen urinary catheter and are embedded in the catheter body. The monitoring line is close to the wall of the three-lumen urinary catheter, and the rear end of the monitoring line extends out of the three-lumen urinary catheter.

[0057] Reference Figure 1In some embodiments of the present invention, a urine volume metering monitoring system further includes: a warning module and a display module. The warning module and the display module are both installed on the upper surface of the monitoring box, and the control processing module is electrically connected to the warning module and the display module respectively. The control processing module processes the inlet amount of the flushing liquid and the outlet amount of the drainage liquid to obtain the inlet flow rate of the flushing liquid, the outlet flow rate of the drainage liquid, and the total outlet amount of the drainage liquid. The display module is used to display the inlet amount of the flushing liquid, the inlet flow rate of the flushing liquid, the outlet amount of the drainage liquid, the outlet flow rate of the drainage liquid, the blood content in the drainage liquid, the pressure information of the bladder, the bladder temperature of the patient, and the liquid temperature of the flushing liquid.

[0058] The warning module is used to send out a warning signal. The control processing module controls the operation of the warning module according to the amount of flushing fluid introduced, the total amount of drainage fluid discharged, the flow rate of flushing fluid introduction, the flow rate of drainage fluid discharge, bladder pressure information, the patient's bladder temperature and the liquid temperature of the flushing fluid.

[0059] When the amount of flushing fluid introduced is higher than the set introduction amount threshold, it is considered that too much flushing fluid is introduced, and the control processing module controls the warning module to send a warning signal to remind the medical staff to stop flushing.

[0060] The total amount of drainage fluid drawn is calculated based on the amount of drainage fluid drawn. When the total amount drawn is higher than the set total amount drawn threshold, it is considered that the amount of drainage fluid drawn is excessive and the drainage fluid stored in the drainage component overflows. The control processing module controls the warning module to send a warning signal to remind medical staff to replace the component.

[0061] The introduction flow rate of the flushing liquid is calculated based on the introduction amount of the flushing liquid. When the introduction flow rate of the flushing liquid is lower than the set introduction flow rate threshold, it is considered that the flushing liquid has been introduced. The control processing module controls the warning module to send a warning signal to remind medical staff to replace the new flushing liquid.

[0062] The drainage flow rate of the drainage fluid is calculated based on the drainage volume. When the drainage flow rate of the drainage fluid is lower than the set drainage flow rate threshold, it is considered that blood clots may have accumulated at the wound, blocking the urinary catheter, and the flushing fluid cannot be discharged. The control processing module controls the warning module to send a warning signal to remind medical staff to check the patient's condition.

[0063] When the bladder pressure information is higher than the set pressure threshold, it is considered that the wound may bleed too much, blood clots are gathered, and the urinary catheter is blocked. The bladder pressure increases, and the control processing module controls the warning module to send a warning signal to remind medical staff to check the patient's condition. When the patient's bladder temperature is inconsistent with the liquid temperature of the flushing fluid, the control processing module controls the warning module to send a warning signal. In this embodiment, the flushing process of the patient can be monitored in real time. When the patient has a problem in some aspect, the warning module will send a warning signal to alert medical staff to check the patient.

[0064] In some embodiments of the present invention, the flushing assembly includes: a flushing liquid bag and a flushing pipeline. The flushing liquid bag is used to store the flushing liquid, the flushing pipeline is used to introduce the flushing liquid into the three-lumen urinary catheter, the flushing liquid bag is connected to one end of the flushing pipeline, the hydraulic regulating valve is installed at one end of the flushing pipeline, the other end of the flushing pipeline is connected to one end of the three-lumen urinary catheter, and the heating modules are all arranged on the flushing liquid bag. The temperature monitoring module for monitoring the liquid temperature of the flushing liquid is arranged on the flushing liquid bag, and the flow monitoring module for collecting the amount of flushing liquid introduced into the three-lumen urinary catheter is arranged in the center of the pipeline of the flushing pipeline.

[0065] The drainage assembly includes: a drainage fluid bag and a drainage pipeline. The drainage pipeline is used to draw out the drainage fluid flowing out of the three-lumen urinary catheter, the drainage fluid bag is used to store the drainage fluid, the drainage fluid bag is connected to one end of the drainage pipeline, and one end of the drainage pipeline is connected to one end of the three-lumen urinary catheter. The image acquisition module is arranged on the outer surface of the drainage pipeline, and the image acquisition module collects image information of the drainage fluid in the drainage pipeline. The flow monitoring module for collecting the drainage amount of the drainage fluid flowing out of the three-lumen urinary catheter is arranged in the center of the pipeline of the drainage pipeline.

[0066] A control method for a urine volume measurement monitoring system according to a second embodiment of the present invention is applied to a urine volume measurement monitoring system according to a first embodiment of the present invention, referring to Figure 2 , a control method of a urine volume measurement monitoring system comprises the following steps:

[0067] Step S100, the flow monitoring module collects the amount of flushing fluid introduced into the three-lumen urinary catheter and the amount of drainage fluid flowing out of the three-lumen urinary catheter;

[0068] Step S200, controlling the processing module to obtain the patient's urine volume according to the inlet volume and outlet volume;

[0071] Step S500, according to the urine volume and blood content, the control processing module controls the operation of the hydraulic regulating valve to adjust the flow rate of the flushing liquid.

[0072] In this embodiment, the flow monitoring module collects the amount of flushing fluid introduced and the amount of drainage fluid drawn out, and the control processing module obtains the patient's urine volume according to the difference between the amount of drainage fluid drawn out and the amount of flushing fluid introduced. The image acquisition module collects the image information of the drainage fluid, and the control processing module performs color recognition on the image information and recognizes the color of the drainage fluid, thereby determining the blood content of the drainage fluid. According to the obtained urine volume and blood content, the control processing module controls the operation of the hydraulic regulating valve, adjusts the flow rate of the flushing fluid, and controls the liquid speed of the bladder flushing. The patient's urine volume is monitored in real time, and the image information is processed for image color recognition, and the blood content in the drainage fluid is objectively judged according to the recognition result. According to the obtained urine volume and blood content, the flow rate of the flushing fluid is accurately adjusted through the hydraulic regulating valve, which is conducive to the patient's safe perioperative period, reducing postoperative complications, and bringing a good experience to the patient, so as to prevent the problem of subjective judgment of blood content and improper selection of flushing speed, which affects the bladder flushing effect.

In other words, due to light problems, when the color recognized by the image color contains slightly reddish and light red, and the proportion of light red is greater than that of slightly reddish, the output color recognition result is light red. The light red color is compared with the set color card to obtain the amount of blood in the drainage fluid at this time.
