[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more apparent, various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in various embodiments of the present invention to help readers better understand the present invention. However, even without these technical details and various variations and modifications based on the following embodiments, the technical solutions claimed in the present invention can still be implemented.

[0030] Example 1:

[0031] In the existing technology, taking the postoperative management process of hepatobiliary surgery as an example, the control of the drainage speed of abdominal drainage is crucial. If the drainage fluid is discharged too quickly, it may cause a sudden drop in abdominal pressure, increase the risk of hypovolemic discomfort or abnormal anastomotic tension; while too slow drainage may lead to fluid retention in the abdominal cavity, induce infection or affect the healing of the surgical area. In addition, when abnormal components such as fresh blood, purulent exudate or changes in bile properties appear in the drainage fluid, the traditional manual timed observation drainage method is difficult to capture sudden changes in the drainage process in real time, and may not be able to complete early intervention for complications such as intra-abdominal bleeding, infection or bile leakage in time.

[0032] In order to solve the above problems, an embodiment of the present invention provides a drainage control device.

[0033] Compared with the prior art, the embodiments of the present invention adopt a flow regulation module to regulate the liquid flow of the drainage fluid in the drainage tube according to the regulation instruction, adopt a drainage detection module to detect the liquid flow and liquid composition of the drainage fluid, and adopt a processing module to generate alarm information according to the liquid flow and liquid composition. While realizing the regulation of the liquid flow in the drainage tube, it also realizes the real-time monitoring of the liquid flow and liquid composition in the drainage tube, thereby solving the problem that the patient fails to detect sudden conditions in time during the drainage process.

[0034] The structure of the drainage control device of this embodiment is described in detail below. The following content is only implementation details provided for ease of understanding and is not necessary for implementing this solution.

[0035] An embodiment of the present invention provides a drainage control device, such as Figure 1 FIG. 1 is a schematic diagram of a drainage control device 100 , which includes a flow regulating module 101 , a drainage detection module 102 , and a processing module 103 .

[0036] A flow regulating module 101 is connected to the processing module 103 and is used to regulate the flow of the drainage fluid in the drainage tube according to the regulation instruction;

[0037] The drainage detection module 102 is connected to the processing module 103 and is used to detect the liquid flow rate and liquid composition of the drainage fluid;

[0038] The processing module 103 is used to generate adjustment instructions and generate alarm information according to the liquid flow rate and liquid composition.

[0039] It should be noted that the drainage control device in this embodiment achieves relative fixation between the drainage tube and the drainage control device by clamping the drainage tube, rather than invasively fixing the drainage tube or the drainage container. The structure in the drainage control device will not come into direct contact with the drainage tube and the drainage liquid in the drainage container to avoid contamination of the drainage control device.

[0040] It should be noted that the drainage tube in this embodiment is generally a silicone tube or a polyurethane tube, and the drainage tube is preferably a transparent drainage tube.

[0041] In this embodiment, it can be a separate box-shaped fixing module, which is provided with a pipe groove that matches the drainage tube. The drainage tube is fixed in the box-mounted fixing module through the pipe groove to achieve fixation of the drainage tube without squeezing the drainage tube. The box-shaped fixing module is provided with a flow regulating module 101 and a drainage detection module 103. In addition, the drainage tube can also be fixed by clamping the drainage tube through the flow regulating module 101. In one example, the flow regulating module 101 also has a pipe groove that partially matches the drainage tube to achieve fixation of the drainage tube without squeezing the drainage tube. In this embodiment, there is no limitation on the fixing method of the drainage control device 100 and the drainage tube.

[0042] In some embodiments, the flow regulating module 101 includes a pipe trough module, which includes a pipe trough adjustment component and a pipe trough. The pipe trough adjustment component is used to adjust the diameter or width of the pipe trough to accommodate drainage tubes of different diameters. In this example, the pipe trough adjustment component includes, but is not limited to, an adjustable knob, and adjusting the adjustable knob adjusts the diameter or width of the pipe trough.

[0043] In the drainage control device 100 , the flow regulating module 101 and the drainage detection module 102 are electrically connected to the processing module 103 respectively, so as to enable data transmission. The connection methods include but are not limited to CAN bus connection.

[0044] The flow regulating module 101 clamps and squeezes the drainage tube according to the regulation instructions sent by the processing module 103 to adjust the flow rate of the drainage fluid in the drainage tube. In this embodiment, the regulation instructions include but are not limited to adjusting parameters such as drainage time, liquid flow rate, number of drainages, and drainage time interval.

[0045] The drainage detection module 102 is provided with sensors that detect liquid flow and liquid composition. The sensors in the drainage detection module 102 are generally configured to be attached to the drainage tube, rather than being inserted into the tube in an invasive manner, and will not come into contact with the drainage fluid in the tube. For example, an ultrasonic sensor can be used to determine the liquid flow in the drainage tube. This sensor transmits an ultrasonic signal, receives a frequency-shifted signal reflected by particles or bubbles in the fluid, and calculates the flow rate to determine the liquid flow in the drainage tube. For another example, an infrared sensor can emit infrared light to illuminate the drainage tube. The concentration of infrared protein in the drainage fluid can be determined based on the light waves transmitted or reflected by the liquid in the drainage tube, thereby determining the presence of blood components in the drainage fluid.

[0046] In one example, if Figure 2 The drainage control device 100 is shown in the schematic diagram. The drainage tube passes through a flow regulating module 101. Pipe grooves (not shown) are provided at both ends of the flow regulating module 101 to secure the drainage tube and prevent it from being squeezed. The middle portion of the flow regulating module 101 clamps the drainage tube to achieve flow regulation. A drainage detection module 102 is used to detect the flow rate and composition of the liquid in the drainage tube.

[0047] The processing module 103 generates an adjustment instruction based on the preset drainage parameters or the externally input drainage parameters to control the flow adjustment module 101 to adjust the liquid flow of the drainage fluid in the drainage tube according to the adjustment instruction. In this embodiment, the drainage parameters include but are not limited to the drainage time, liquid flow, drainage time interval, number of drainages, etc. The preset drainage parameters are pre-set, for example, they can be set based on actual experience; the externally input drainage parameters can be input through the input device on the drainage control device 100 (the input device includes but is not limited to a touch screen or a button), or they can be drainage parameters sent to the drainage control device 100 by an external device through a communication connection, which is not limited in this embodiment.

[0048] Furthermore, processing module 103 receives liquid flow and composition data from drainage detection module 102. When the liquid flow and composition in the drainage tube meet preset alarm conditions, processing module 103 generates an alarm message. In this embodiment, the alarm message includes, but is not limited to, specific alarm items and alarm levels. A sudden change in flow rate within a preset period is defined as a flow rate mutation. If the sudden change in flow rate of the drainage fluid is a first flow rate value A, the alarm level is determined to be 1; if the sudden change in flow rate is a second flow rate value B, the alarm level is determined to be 2.

[0049] The drainage control device in this embodiment is clamped on the drainage tube. The flow regulation module in the device adjusts the liquid flow of the drainage fluid in the drainage tube according to the regulation instruction, thereby realizing the regulation of the liquid flow in the drainage tube; the liquid flow and liquid composition of the drainage fluid are detected by the drainage detection module, thereby realizing real-time monitoring of the liquid flow and liquid composition of the drainage fluid; the processing module generates regulation instructions, and generates alarm information according to the liquid flow and liquid composition. When the liquid flow and liquid composition in the drainage tube are abnormal, an abnormal alarm is issued to help medical staff to promptly discover the patient's sudden condition, thereby realizing closed-loop management of the entire drainage process, while ensuring the accuracy of drainage detection, significantly improving the safety and efficiency of clinical operations.

[0050] In addition, since the drainage control device of the embodiment of the present application is directly clamped on the drainage tube, it does not need to come into contact with the drainage fluid in the drainage tube, and can detect the liquid flow and liquid composition of the drainage fluid in the drainage tube. During actual use, there is no need to modify the existing drainage pipeline. It is compatible with all standardized drainage tubes (such as silicone tubes, polyurethane tubes) and can be quickly deployed through an external clamping device.

[0051] In some embodiments, as Figure 3 As shown, the drainage control device 100 also includes a communication module 104, which is connected to the processing module 103 and is used to send liquid flow, liquid composition and alarm information to a preset terminal. In this embodiment, the drainage control device is interconnected with other equipment or medical systems through the communication module. The communication module 104 can be a wireless transmission module or a wired transmission module. In actual application scenarios, the communication module 104 can also encrypt the transmitted data, for example, after encrypting the data through the AES-256 (Advanced Encryption Standard) protocol, the data is uploaded to the hospital's private cloud or a third-party medical cloud platform.

[0052] In this embodiment, the wireless transmission module includes, but is not limited to, Bluetooth, WiFi, NFC, Zigbee, and cellular network communication modules. For example, the communication module 104 is a low-power wireless transmission module that supports Bluetooth 5.0 and WiFi dual-mode communication and supports seamless switching between the hospital information system (HIS) and the cellular network.

[0053] In some embodiments, the flow regulation module 101 includes a clamp 1010 and a pressure sensor 1012. The clamp 1010 is used to control the liquid flow rate by applying pressure to the drainage tube, and the pressure sensor 1012 is used to detect the pressure applied by the clamp to the wall of the drainage tube. The clamp 1010 mechanically adjusts the cross-sectional area of ​​the drainage tube to control the liquid flow rate. By real-time monitoring of the pressure applied by the clamp to the wall of the drainage tube, the operating status of the clamp 1010 is monitored, allowing for precise regulation of the liquid flow rate in the drainage tube.

[0054] In one example, the clamp 1010 is fixed to the drainage tube 10 cm away from the body surface outlet and adjusted according to the diameter of the drainage tube. The silicone gasket of the clamp 1010 is in close contact with the tube wall and mechanical pressure is applied to the drainage tube to fix the drainage tube.

[0055] Exemplarily, clamp 1010 is a stepper motor-driven, pressure-bar-type clamp, whose pressure intensity is linearly proportional to the voltage signal of the adjustment command. The clamping force has a dynamic adjustment range of 0-15N (corresponding to a drainage rate of 0-500ml / h). A pressure sensor 1012 (range 0-20N, accuracy ±0.1N) monitors the pressure exerted by clamp 1010 on the drainage tube wall in real time.

[0056] In some embodiments, the processing module 103 is further configured to adjust the regulation instructions based on the pressure and the real-time flow rate of the drainage fluid. In actual application scenarios, due to differences in drainage tube materials and pressures in the patient's body, the amount of change in the flow rate of the drainage tubes of different patients and different materials may vary under the same mechanical pressure applied by the clamp 1010. Therefore, it is necessary to dynamically adjust the mechanical pressure of the clamp 1010 in the regulation instructions based on the mechanical pressure collected by the pressure sensor 1012 and the real-time flow rate of the drainage fluid, so as to achieve precise regulation of the drainage flow rate in the drainage tube under different circumstances.

[0057] like Figure 4 The flow regulation flow chart of the flow regulation module 101 is shown. The flow regulation of the flow regulation module 101 may include the following steps:

[0058] S41, determining the target regulation flow;

[0059] For example, in this embodiment, the processing module 103 is configured to determine a target regulated flow rate and generate corresponding regulation instructions based on preset drainage parameters or drainage parameters received by the processing module 103. For example, the processing module 103 is configured to determine that the target regulated flow rate is 50 ml / h based on the drainage parameters pre-set by the drainage control device 100, and generate corresponding regulation instructions.

[0060] S42, obtaining the real-time liquid flow rate and the real-time pressure of the clamp;

[0061] Specifically, in response to the adjustment instruction generated by the processing module 103 , the real-time flow rate of the drainage fluid in the drainage tube and the real-time pressure applied by the clamper 1010 to the drainage tube are detected by the adjustment module 101 .

[0062] S43, adjusting the regulation instruction according to the real-time liquid flow and real-time pressure;

[0063] Specifically, the processing module 10 is configured to adjust the control instructions based on the real-time liquid flow rate and real-time pressure. Specifically, it can dynamically compensate for flow deviations caused by pipeline deformation based on a PID (Proportional Integral Differential) algorithm to ensure that the error between the preset drainage volume and the actual flow rate is ≤3%.

[0064] In some embodiments, the drainage detection module 102 includes a flow detection module 1020 and a component identification module 1024. The flow detection module 1020 and component identification module 1024 are configured to be attached to the drainage tube. The flow detection module 1020 is used to detect the fluid flow rate, and the component identification module 1024 is used to detect the hemoglobin concentration and / or bilirubin concentration of the drainage fluid. In this embodiment, the drainage detection module updates the fluid flow rate and fluid composition data at preset intervals to enable real-time monitoring of the drainage fluid during the drainage process. For example, the instantaneous flow rate data of the drainage tube is updated every 10 milliseconds. In this embodiment, the flow detection module 1020 and component identification module 1024 can also be configured to be attached to the drainage container.

[0065] In one example, flow detection module 1020 is a clamp-on ultrasonic Doppler flowmeter. It transmits ultrasonic signals and receives frequency-shifted signals reflected by particles or bubbles in the fluid. Based on the Doppler effect, it calculates flow velocity and infers flow rate. Flow detection module 1020 is externally mounted on the drainage tube wall, eliminating the need to cut into the drainage tube or come into contact with the drainage fluid.

[0066] In this embodiment, the component identification module 1024 includes but is not limited to a sensor with a fiber optic probe. The fiber optic probe is placed on the surface of the drainage tube, and a specific wavelength (such as blue light with a wavelength of 450-470nm and green light with a wavelength of 520-550nm) is emitted to penetrate the wall of the drainage tube to detect the difference in the absorption / scattering characteristics of the drainage fluid to light, thereby determining the bilirubin concentration in the drainage fluid.

[0067] In this embodiment, the component identification module 1024 includes but is not limited to a micro-spectral analysis unit, which illuminates the drainage fluid flow area through a standardized light source, uses a high-resolution industrial camera to capture multi-band (such as visible light to near-infrared) reflection or transmission spectra, and combines a deep learning model to reconstruct the spectral response of the hemoglobin concentration sensitive band (such as 460-490nm) to determine the hemoglobin concentration in the drainage fluid.

[0068] In this embodiment, component identification module 1024 may also include, but is not limited to, an impedance sensor array capable of identifying pus cells based on differences in cell membrane electrical properties. The impedance sensor array includes a gold electrode microfluidic channel with a spatial resolution of ≤50 μm. In this embodiment, when the number of pus cells detected exceeds a preset pus cell concentration threshold, processing module 103 is triggered to generate a corresponding alarm.

[0069] In this embodiment, the processing module 103 is configured with a multi-dimensional feature fusion model constructed based on a support vector machine (SVM). The model input is the flow mutation gradient (ΔQ / Δt), the time series change of hemoglobin absorbance (or hemoglobin concentration), and the time series change of bilirubin concentration. The model output is alarm information.

[0070] For example, the drainage fluid flow rate and flow composition detected by the drainage detection module 102 are obtained. Based on historical records of the fluid flow rate, the flow rate mutation gradient, the time series changes in hemoglobin absorbance, and the time series changes in bilirubin concentration are obtained. Using a multi-dimensional feature fusion model, corresponding alarm information is generated. Optionally, the alarm information can be set to Level I (early warning) or Level II (emergency alarm). In actual application scenarios, different alarm modes can be set based on different alarm information.

[0071] In some embodiments, the drainage control device 100 may include indicator lights, such as red, yellow, and green indicator lights, where red indicates that the drainage control device has an alarm, green indicates that the drainage control device is operating normally, and yellow indicates that the drainage control device is operating abnormally.

[0072] In some embodiments, the drainage control device 100 further includes a display screen 105 for displaying liquid flow rate, liquid composition, and alarm information, enabling real-time presentation of drainage information during the drainage process. The display screen 105 can also display information such as device operating status and network status. Furthermore, when abnormal liquid components or alarm information are present, the abnormal components and alarm information can be highlighted on the display screen 105, for example, using a different font color or flashing.

[0073] In some embodiments, the drainage control device 100 further includes a capacity detection module 106 connected to the processing module 103, and its connection mode includes but is not limited to a wired connection and a wireless connection (the connection mode is not shown in the figure), such as Figure 5 As shown, the capacity detection module 106 is attached to the outer wall of the drainage container 30 connected to the drainage tube 20 and is used to detect the volume of the drainage liquid in the drainage container 30. In this embodiment, the capacity detection module 106 is preferably a capacitive sensor or a photoelectric liquid level sensor. By installing the liquid level sensor on the outer wall of the drainage container 30, it detects the height of the drainage liquid in the drainage container 30. For example, when the capacity detection module 106 detects that the liquid volume in the drainage container 30 has reached the preset drainage capacity, the processing module 103 sends an adjustment instruction "adjust the liquid flow rate to 0" to the flow adjustment module 101 to stop drainage.

[0074] On the other hand, when the capacity detection module 106 detects that the height of the drainage liquid in the drainage container 30 exceeds the alarm threshold (for example, the scale line corresponding to 800 ml), it means that the drainage liquid in the drainage container 30 has reached the alarm capacity, and the processing module 103 is triggered to generate an alarm message.

[0075] In some embodiments, the drainage control device 100 also includes a weight detection module. The weight detection module in this embodiment is connected to the processing module 103, and its connection method includes but is not limited to wired connection and wireless connection. The weight detection module is connected to the processing module and is provided with a fixing component and a weight sensor. The fixing component is used to fix the drainage container connected to the drainage tube, and the weight sensor is used to detect the weight of the drainage container.

[0076] In one example, the weight detection module's fixing components include fixing hooks or fixing rings, etc., disposed at both ends of the weight detection module. The fixing components are used to secure the drainage container while also securing the weight detection module and the drainage container to the edge of a bed or the patient's body.

[0077] In this embodiment, the corresponding drainage concentration is pre-set according to the type of drainage fluid, and then the actual volume of the drainage fluid is determined based on the weight of the drainage fluid in the drainage container detected by the weight detection module.

[0078] In this embodiment, the processing module 103 can determine the volume of the drainage fluid in the drainage container according to the drainage fluid data sent by the capacity detection module 106 and the weight detection module, and then determine the accurate drainage fluid capacity based on a preset algorithm.

[0079] In some embodiments, the weight detection module further includes a height adjustment component for adjusting the length of the weight detection module. The height adjustment component on the weight detection module adjusts the overall length of the weight detection module by adjusting its own length, thereby adjusting the hanging height of the drainage container. The height adjustment component can drive a stepper motor in the height adjustment component based on a height adjustment instruction sent to the weight detection module by the processing module 103 to adjust the length of the adjustment component, thereby adjusting the length of the weight detection module and adjusting the hanging height of the drainage container.

[0080] In some embodiments, the drainage control device 100 further includes a signal indicator light for displaying the communication status of the communication module, so as to quickly determine the communication status of the drainage control device 100 and to quickly troubleshoot equipment failures.

[0081] In some embodiments, the drainage control device 100 further includes a power supply module for providing power for operation of the device.

[0082] Example 2

[0083] The embodiment of the present invention further relates to a drainage control method, which is applied to the drainage control device described in the above embodiment, such as Figure 6 As shown, the method may specifically include the following steps:

[0084] S601, receiving traffic diversion parameters sent by the control terminal and generating adjustment instructions corresponding to the traffic diversion parameters;

[0085] S602, regulating the flow of the drainage tube according to the regulation instruction, and monitoring the liquid flow and liquid composition of the drainage fluid in the drainage tube in real time;

[0086] S603, sending the liquid flow rate, liquid composition and alarm information to the control terminal, wherein the alarm information is generated based on the liquid flow rate and liquid composition.

[0087] In this embodiment, in response to drainage parameters sent by the control terminal, adjustment instructions corresponding to the drainage parameters are generated. Based on the adjustment instructions, mechanical pressure is applied to the drainage tube to achieve timed and quantitative flow adjustment. The liquid flow rate and liquid composition of the drainage fluid are monitored in real time. When the liquid flow rate and liquid composition reach their respective alarm thresholds, an alarm message is generated.

[0088] Then, the liquid flow, liquid composition and alarm information are sent to the control terminal at preset time intervals to achieve real-time monitoring of the drainage process. When the liquid flow and liquid composition in the drainage tube are abnormal, an abnormal alarm is issued to help medical staff detect the patient's sudden condition in time.

[0089] Example 3:

[0090] Embodiments of the present invention also relate to a drainage control system.

[0091] The structure of the drainage control system of this embodiment is described in detail below. The following content is only implementation details provided for ease of understanding and is not necessary for implementing this solution.

[0092] The embodiment of the present invention further provides a drainage control system, such as Figure 7 As shown, the drainage control system 300 includes: a drainage control device 100 and a control terminal 200, wherein:

[0093] The control terminal 200 is configured to generate drainage parameters according to an operation instruction acting on the control terminal 200, send the drainage parameters to the drainage control device 100, and display the liquid flow rate, liquid composition and alarm information;

[0094] The drainage control device 100 is configured to generate adjustment instructions according to the drainage parameters, adjust the drainage tube to perform drainage, and send liquid flow, liquid composition and alarm information to the control terminal 200.

[0095] The control terminal 100 can be an independent terminal device or a terminal device that has an application corresponding to the drainage control device 100 installed, such as a mobile phone with a specified application installed. In addition, this embodiment does not limit the operating system of the control terminal 200, and can be, for example, Android, iOS, Windows, Linux, and Hongmeng system.

[0096] In this embodiment, the operation instructions acting on the control terminal 200 can be operation instructions directly acting on the control terminal interaction module, such as operation instructions acting on a touch screen or button, or operation instructions sent to the control terminal 200 from the cloud.

[0097] The communication connection between the control terminal 200 and the drainage control device 100 can be through a local area network connection or a wide area network connection, which is not limited in this embodiment.

[0098] In one example, after the drainage control device 100 is fixed to the drainage tube, the preset application in the control terminal 200 is set to "drainage 4 times a day, single time ≤300ml", or "drainage is opened once at XX time, each time 200ml", or "limit the total drainage volume in 24 hours to ≤1500ml"; and whether to turn on bilirubin concentration monitoring (the alarm threshold is 5mg / dL), adjust the hemoglobin absorbance fluctuation threshold, etc., all of which can be set according to user needs.

[0099] In this embodiment, the operation instruction input by the user is sent to the drainage control device 100 through the control terminal 200. The communication module 104 in the drainage control device 100 receives the operation instruction and transmits it to the processing module 103. The processing module 103 obtains the corresponding drainage parameters based on the operation instruction, and generates the corresponding adjustment instruction based on the drainage parameters to control the flow adjustment module 101 to adjust the flow of the drainage tube.

[0100] Optionally, in this embodiment, the control terminal is installed with a preset application, wherein the control terminal 200 is configured to display a drainage report corresponding to the liquid flow, liquid composition and alarm information on the graphical user interface of the preset application.

[0101] In actual application scenarios, the processing module 103 in the drainage control device 100 is configured to record drainage data such as a single drainage volume and an instantaneous flow corresponding to a preset time point in real time, and send the drainage data to the control device 200 through the communication module 104 according to a preset synchronization time interval.

[0102] A preset application is installed in the control terminal 200. By synchronizing the drainage data and alarm information to the preset application, a drainage report containing time, drainage volume, and liquid composition is generated. The drainage report contains a 24-hour total volume trend chart, component abnormality timestamp, alarm event list, patient basic information, historical information and other information.

[0103] In some embodiments, the control terminal 200 is provided with a display screen, which displays a graphical user interface of a preset application on the display screen, and displays a drainage report corresponding to the liquid flow, liquid composition and alarm information of the drainage tube currently corresponding to the drainage control device 100.

[0104] In some embodiments, the control terminal 200 includes a first terminal 210 and a second terminal 220. The first terminal 210 is a medical terminal. The login account of the preset application in the first terminal 210 is a medical account. The medical account has operation permissions on the drainage control device 100 and can control the drainage control device. The second terminal 220 is a patient terminal. The login account of the preset application in the second terminal 220 is a patient account. The patient account does not have operation permissions on the drainage control device 100, but only has viewing permissions, and can only view the device status and alarm information of the drainage control device.
