Description

Technical Field

[0001] This application relates to the field of interventional robotics technology, and more specifically, to a peristaltic pump door status detection and fluid circuit control method, system, device and medium. Background Technology

[0002] In current interventional procedures, saline infusion is often required, and the status of the peristaltic pump valve is crucial to the safety and reliability of the infusion process. If the peristaltic pump valve accidentally opens during infusion, blood may flow back into the infusion tubing, which will not only contaminate the remaining medication but also cause unforeseen operational risks.

[0003] Currently, some saline infusion devices on the market lack real-time monitoring of the peristaltic pump door status and cannot take swift action to reduce potential harm in the event of abnormalities.

[0004] Therefore, the current intervention process cannot monitor and control the usage status of the peristaltic pump door in a timely manner, which increases the risk of liquid backflow and urgently needs to be addressed. Summary of the Invention

[0005] The main objective of this application is to provide a method, system, device, and medium for peristaltic pump door status detection and fluid circuit control, aiming to solve the problem that the current intervention process cannot timely monitor and control the usage status of the peristaltic pump door, leading to an increased risk of fluid backflow.

[0006] The first aspect of this application proposes a method for peristaltic pump door status detection and fluid circuit control, including: When the peristaltic pump door is detected to be open, it is determined whether the current fluid circuit system is in the start-up state. If the system is not in the startup state, the check valve on the liquid circuit system will not be closed. If the system is in the startup state, determine the fluid delivery status of the fluid circuit system in the startup state; Based on the infusion status, the stop valve on the fluid circuit system is controlled to close, and a corresponding prompt message is generated.

[0007] Furthermore, prior to the step of detecting whether the current fluid circuit system is in the start-up state when the peristaltic pump door is detected to be open, the following steps are included: Based on sensor detection of the peristaltic pump door's closing status; If a peristaltic pump door is detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is closed; If the peristaltic pump door is not detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is open. Further, the step of identifying whether the current fluid circuit system is in an active state includes: Determine whether the fluid delivery pipeline of the current fluid system is in an installation or disassembly state; If it is in the installation or disassembly state, it is determined that it is not in the start state; If it is not in the installation or disassembly state, it is determined that the current liquid circuit system is in the start state.

[0008] Further, the feature is that, if in the start-up state, the step of determining the infusion status of the fluid circuit system in the start-up state includes: Check if the motor of the peristaltic pump is running; If it is in a rotating state, the fluid circuit system is determined to be in a state of fluid delivery; If it is not in a rotating state, the fluid circuit system is determined to be in a state of waiting for infusion. Alternatively, it can be based on the detection of fluid pressure or flow rate in the infusion line using sensors; If the pressure or flow rate of the liquid circuit is within a preset range, the liquid circuit system is determined to be in a state of liquid delivery. If the pressure or flow rate of the liquid circuit is not within the preset range, the liquid circuit system is determined to be in a state of waiting for liquid delivery.

[0009] Furthermore, the step of controlling the closure of the check valve on the fluid circuit system based on the infusion status and generating corresponding prompt information includes: If the infusion status is "awaiting infusion", a corresponding prompt message will be generated; The system identifies the user's shutdown command and, based on the shutdown command, controls the valve of the check valve to squeeze the infusion pipeline, thereby closing the check valve.

[0010] Further, after the step of recognizing the user's closing command and controlling the valve of the check valve to squeeze the infusion pipeline based on the closing command to close the check valve, the procedure includes: Generate a pre-delivery interface and identify the user's delivery instructions based on the pre-delivery interface; The peristaltic pump motor is controlled to rotate based on the delivery command, and the peristaltic pump drives the liquid in the infusion pipeline to flow and be delivered.

[0011] Furthermore, the step of controlling the closure of the check valve on the fluid circuit system based on the infusion status and generating corresponding prompt information includes: If the infusion status is in the infusion state, the valve controlling the stop valve will squeeze the infusion line to close the stop valve, terminate the infusion delivery, and generate a corresponding prompt message to be sent to the user interface.

[0012] The second aspect of this application proposes a system for peristaltic pump door status detection and fluid circuit control, comprising: The identification module is used to identify whether the current fluid circuit system is in the start-up state when the peristaltic pump door is detected to be open; The non-control module is used to prevent the stop valve on the liquid circuit system from closing if it is not in the start-up state; The judgment module is used to determine the infusion status of the fluid circuit system if it is in the startup state. The control module is used to control the closure of the stop valve on the fluid circuit system based on the infusion status and generate corresponding prompt information.

[0013] A third aspect of this application provides a computer device including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the peristaltic pump door state detection and fluid circuit control method described in any one of the above-mentioned methods.

[0014] The fourth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the peristaltic pump door status detection and fluid circuit control method as described in any of the preceding claims.

[0015] Beneficial effects: Separating the identification and control of the start-up and infusion states of the fluid system ensures efficient operation of each link and improves the overall system performance. Different control strategies are adopted based on different states to adapt to various usage scenarios, enhancing the system's applicability and flexibility. The system can make different judgments and control responses based on the fluid system's usage status, accurately identifying the risk of fluid backflow in actual application scenarios, generating prompts at key operational nodes to notify users of the current equipment status, helping users take timely measures, and improving operational convenience and transparency. By real-time monitoring of the peristaltic pump door's opening and closing status, it can respond immediately when the pump door opens to prevent fluid backflow and reduce operational risks during intervention.

[0020] Reference Figure 1 - Figure 2 This application provides a method for peristaltic pump door status detection and fluid circuit control, including steps S1-S4: S1. When the peristaltic pump door is detected to be open, identify whether the current liquid circuit system is in the start-up state; S2. If not in the start-up state, the stop valve 2 on the liquid circuit system is not closed; S3. If it is in the start-up state, determine the liquid delivery status of the liquid circuit system in the start-up state; S4. Based on the infusion status, control the stop valve 2 on the liquid circuit system to close and generate corresponding prompt information.

[0021] In this embodiment, the system first uses sensors to detect the state of the peristaltic pump door. Other types of sensors, such as infrared sensors, ultrasonic sensors, magnetic switches, and proximity switches, can be used to achieve the same function. This step is crucial for timely detection of changes in the pump door's state, ensuring infusion safety. It can proactively prevent safety accidents that may occur due to unexpected pump door opening, such as fluid backflow.

[0022] Once the system confirms the peristaltic pump door is open, it will then determine if the fluid circuit system is in an active state. "Active state" here refers to whether the fluid circuit system is in a usable, operational state, i.e., whether it is already installed or not disassembled. If the system determines that it is not currently in an active state (e.g., during installation or disassembly of the fluid circuit system), it will not perform the closing operation on check valve 2. This decision logic is designed to avoid accidental operation during non-infusion states, reducing unnecessary equipment wear and energy consumption. Furthermore, this design protects medical personnel from interference during maintenance or replacement operations. It improves the system's intelligence and user experience while reducing equipment maintenance costs.

[0023] Once the fluid system is confirmed to be in the startup state, the system will further check the current infusion status, i.e., determine whether it is in a state of waiting for infusion or infusion already in progress. This can be done by monitoring the motor status of peristaltic pump 1 or by directly measuring the pressure and flow rate in the infusion tubing. If the motor is running or the detected fluid pressure and flow rate meet the preset conditions, the system can be determined to be in the process of infusion. Conversely, if the motor stops running or the fluid parameters do not meet the infusion conditions, the system is considered to be in a state of waiting for infusion. This step helps the system to make more accurate responses, ensuring that appropriate measures are taken in different situations. It enhances the adaptability and safety of the system, and can effectively prevent dangerous situations such as fluid backflow under various operating conditions.

[0024] Finally, based on the infusion status determined in the previous step, the system will take corresponding control measures. If the system is in a pre-infusion state, it will generate a prompt message to notify the user to close the pump door to ensure safe preparation before infusion. If the system is already in an infusion state, it will immediately close check valve 2, using a motor-driven valve to squeeze the infusion tubing, preventing further fluid flow, and simultaneously generate a warning message to alert medical staff through auditory and visual means. This series of actions responds quickly and accurately to abnormal pump door opening events, greatly reducing potential risks. It provides immediate fault handling capabilities, ensures operational safety, and helps operators quickly locate problems.

[0025] In one embodiment, before the step of identifying whether the current fluid circuit system is in a startup state when the peristaltic pump door is detected to be open, the following steps are included: S10. Detect the closing status of the peristaltic pump door based on sensors; S11. If a peristaltic pump door is detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is closed; S12. If the peristaltic pump door is not detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is open.

[0026] In this embodiment, the system needs to detect the closing state of the peristaltic pump door using a pump door detection device 4. This is achieved by detecting the pump door's closing state using sensors such as photoelectric sensors, proximity switches, or magnetic switches. The photoelectric sensor is installed in the closed position of the pump door. When the pump door is closed, the light from the photoelectric sensor is blocked, indicating a closed state; when the pump door is open, the light passes through, indicating an open state. The proximity switch is also installed in the closed position of the pump door. When the pump door is closed, the proximity switch detects an object, indicating a closed state; when the pump door is open, the proximity switch does not detect an object, indicating an open state. The magnetic switch has a small magnet installed on the pump door and a magnetic switch installed in a fixed position. When the pump door is closed, the magnetic switch detects a magnetic field, indicating a closed state; when the pump door is open, the magnetic switch does not detect a magnetic field, indicating an open state. The system performs an initialization check upon startup to determine the initial state of the pump door. Then, during system operation, the pump door's state is continuously monitored to ensure real-time control of its opening and closing status. By using or combining these sensors, the system can detect the status of the pump door with high precision, ensuring the safety and reliability of the infusion process.

[0027] In one embodiment, the step of identifying whether the current fluid circuit system is in an active state includes: S20. Determine whether the infusion pipeline 3 of the current liquid circuit system is in the installation or disassembly state. S21. If it is in the installation or disassembly state, it is determined that it is not in the start state; If it is not in the installation or disassembly state, it is determined that the current liquid circuit system is in the start state.

[0028] In this embodiment, it is determined whether the infusion tubing 3 of the current fluid system is in an installation or disassembly state. This is because during installation or disassembly, the fluid system should not perform any infusion-related control operations to avoid interfering with the operation of medical personnel or causing unnecessary equipment damage. Specific determination methods may include the following: 1. Physical sensor detection: Sensors, such as proximity switches or photoelectric sensors, can be installed at the connection points of the fluid system to detect whether the tubing is connected correctly. If the sensor detects that the tubing is not connected or is being connected, the system will determine it to be in an installation or disassembly state. 2. Manual operation confirmation: A manual operation button or interface is provided for medical personnel to manually confirm when starting installation or disassembly of the tubing, ensuring more accurate system judgment.

[0029] If the system determines that the infusion line 3 of the current fluid system is in an installation or disassembly state, it will determine that the fluid system is not in the start state. At this time, the system will not perform any infusion-related control operations, such as closing the check valve 2. Specific technical implementations may include: setting control logic in the software to disable all infusion-related control functions when an installation or disassembly state is detected, ensuring the system does not misoperate. Simultaneously, a clear prompt message should be displayed on the user interface to inform medical personnel that the system is currently in an installation or disassembly state, preventing accidental operation.

[0030] In one embodiment, if the system is in an active state, the step of determining the infusion status of the fluid circuit system in the active state includes: S30. Check whether the motor of peristaltic pump 1 is rotating; S31. If it is in a rotating state, the fluid circuit system is determined to be in a state of fluid delivery. S32. If it is not in a rotating state, the fluid circuit system is determined to be in a state of waiting for infusion. S33, or, based on the sensor detection of the liquid pressure or liquid flow in the infusion line 3; S34. If the liquid circuit pressure or liquid circuit flow rate is within the preset range, the liquid circuit system is determined to be in the liquid delivery state. S35. If the liquid circuit pressure or liquid circuit flow rate is not within the preset range, the liquid circuit system is determined to be in a state of waiting for liquid delivery.

[0031] In this embodiment, the system detects whether the motor of the peristaltic pump 1 is rotating. The rotation status of the motor directly reflects whether the infusion system is working. Specific detection methods may include: determining whether the motor is rotating by detecting changes in the motor's current. When the motor is rotating, the current will fluctuate significantly, while the current is relatively stable when stationary. Alternatively, an encoder can be installed on the motor, and the rotation status can be determined by the pulse signals fed back by the encoder. The encoder can provide high-precision speed and position information. If the system detects that the motor of the peristaltic pump 1 is rotating, it will determine that the infusion system is in an infusion-ready state. This means that the infusion process is underway, and the system needs to take appropriate control measures to keep the pump door properly closed. If the system detects that the motor of the peristaltic pump 1 is not rotating, it will determine that the infusion system is in a pre-infusion state. This means that the infusion process has not yet started, and the system needs to take appropriate control measures, such as prompting the user to close the pump door to ensure that pre-infusion preparations are completed.

[0032] Alternatively, a pressure sensor can be installed on infusion line 3 to detect pressure changes within the line. When the pressure is within a preset range, the system is determined to be in infusion mode; otherwise, it is determined to be in a state awaiting infusion. Or, a flow sensor can be installed on infusion line 3 to detect flow changes within the line. When the flow rate is within a preset range, the system is determined to be infusion mode; otherwise, it is determined to be in a state awaiting infusion. If the system detects that the pressure or flow rate in infusion line 3 is within a preset range, it will determine that the infusion system is in infusion mode. This means that the infusion process is underway, and the system needs to take appropriate pump gate control measures.

[0033] In one embodiment, the step of controlling the closure of the stop valve 2 on the fluid circuit system based on the infusion status and generating corresponding prompt information includes: S40. If the infusion status is a pending infusion status, generate a corresponding prompt message; S41. Identify the user's closing command, and based on the closing command, control the valve of the stop valve 2 to squeeze the infusion pipeline 3, so that the stop valve 2 closes.

[0034] In this embodiment, the infusion system has been determined to be in a state of imminent infusion. This means that the infusion process has not yet started, but the peristaltic pump door has been accidentally opened, posing a potential safety risk. To ensure safe preparation before infusion, the system needs to generate corresponding prompts to inform the user of the current status and required actions. Specific technical implementations may include: 1. User interface prompts: Displaying clear prompts on the device's screen, such as: "Peristaltic pump door not closed, please close the pump door to continue operation." Simultaneously, an audible prompt can be issued through a built-in speaker or buzzer to remind medical staff of the current status, or a visual warning can be provided through flashing or constant illumination of LEDs or other indicator lights. After generating the prompts, the system initiates a program to receive the user's closing command, actively recognizing the user's closing command. When the user confirms closing the peristaltic pump door on the interface, the system recognizes the user's closing command and takes corresponding control measures to close the check valve 2. Specific technical implementations may include: providing a confirmation button on the user interface; after the medical staff closes the pump door, clicking this button allows the system to recognize the closing command. Once the system recognizes the user's closing command, it will perform the following operations: Start the motor to drive the valve of check valve 2 inward, disengaging it from the infusion line 3 and restoring the flow of fluid. Update the current status on the user interface, displaying the message "Peristaltic pump door closed, infusion can begin." The main purpose of this step is to ensure that the system can respond promptly and restore the normal state of the fluid line after the user confirms the pump door is closed, ensuring the safe conduct of the infusion process. The technical benefits include improved system automation and reliability, reduced human error, and guaranteed smooth infusion.

[0035] In one embodiment, after the step of recognizing the user's closing command and controlling the valve of the check valve 2 to squeeze the infusion line 3 based on the closing command, thereby closing the check valve 2, the procedure includes: S50. Generate a pre-delivery interface and identify the user's delivery instructions based on the pre-delivery interface; S51. Based on the delivery command, control the motor of the peristaltic pump 1 to rotate, and drive the liquid in the infusion pipeline 3 to flow and be delivered by the peristaltic pump 1.

[0036] In this embodiment, after recognizing the user's closing command and controlling the closure of the check valve 2, a pre-delivery interface is generated, and the user's delivery command is recognized based on this interface. Specific technical implementations may include: generating a pre-delivery interface on the device's display screen, which includes infusion setting options such as infusion rate and total infusion volume. A confirmation button is provided on the pre-delivery interface; after the user sets the infusion parameters, clicking this button allows the system to recognize the delivery command. The user selects infusion parameters and confirms the delivery command via the touchscreen. Alternatively, physical buttons can be provided on the device, allowing the user to select infusion parameters and confirm the delivery command via these buttons. Furthermore, voice recognition functionality can be integrated, allowing the user to set infusion parameters and confirm the delivery command via voice commands.

[0037] After the system recognizes the user's delivery command, it controls the motor of the peristaltic pump 1 to rotate, driving the liquid in the infusion line 3 to flow and deliver. The rotation angle and speed of the peristaltic pump 1 are precisely controlled by a stepper motor or servo motor to ensure the accuracy of the infusion rate.

[0038] In one embodiment, the step of controlling the closure of the stop valve 2 on the fluid circuit system based on the infusion status and generating corresponding prompt information includes: S60. If the infusion state is in the infusion state, the valve of the control stop valve 2 is squeezed to close the infusion pipeline 3, thereby terminating the infusion delivery and generating a corresponding prompt message to be sent to the user interface.

[0039] In this embodiment, when the system determines that the infusion status is in progress, if the pump door is detected to be open, an automatic pump door closing procedure needs to be initiated to ensure the safety of the infusion process. At this time, the motor is directly started to drive the valve of the check valve 2 to move towards the infusion line 3, causing the valve of the check valve 2 to squeeze the infusion line 3 and close the check valve 2. A sensor is used to detect whether the check valve 2 is squeezed in place to ensure that the check valve 2 is completely closed. For example, an optocoupler sensor is used to detect whether the check valve 2 or other components moving with the check valve 2 are detected within a specified range, thereby determining whether the check valve 2 has moved a sufficient length to completely squeeze the infusion line 3, preventing the liquid from flowing. At the same time, the motor of the peristaltic pump 1 can be stopped to ensure that the infusion pump stops rotating and the infusion delivery is stopped. A clear prompt message is displayed on the device's display screen, such as: "The peristaltic pump door has automatically closed, the infusion has been terminated, please check the operating table." At the same time, an audible prompt is issued through the built-in speaker or buzzer to remind medical staff to pay attention to the current status, or a visual warning is provided through the flashing or constant illumination of LED lights or other indicator lights.

[0042] Furthermore, the identification module 100 includes: The disassembly / assembly judgment unit is used to determine whether the infusion pipeline 3 of the current liquid circuit system is in the installation or disassembly state. The non-startup determination unit is used to determine that the device is not in the startup state if it is in the installation or disassembly state.

[0043] Furthermore, the judgment module 300 includes: The rotation detection unit is used to detect whether the motor of the peristaltic pump 1 is in a rotating state; The first infusion judgment unit is used to determine that the fluid circuit system is in the infusion state if it is in a rotating state; The first infusion-ready judgment unit is used to determine that the fluid circuit system is in an infusion-ready state if it is not in a rotating state. A pressure detection unit is used to detect, or based on a sensor, the pressure or flow rate of the fluid in the infusion line 3. The second infusion judgment unit is used to determine that the infusion system is in an infusion state if the infusion pressure or infusion flow rate is within a preset range. The second infusion-ready determination unit is used to determine that the liquid circuit system is in an infusion-ready state if the liquid circuit pressure or liquid circuit flow rate is not within a preset range.

[0044] Furthermore, the control module 400 includes: The first prompting unit is used to generate corresponding prompting information if the infusion state is a waiting infusion state; The first closing unit is used to identify the user's closing command and, based on the closing command, control the valve of the stop valve 2 to squeeze the infusion pipeline 3, so that the stop valve 2 is closed. Furthermore, the control module 400 also includes: The interface generation unit is used to generate a preliminary delivery interface and identify the user's delivery instructions based on the preliminary delivery interface. The rotation control unit is used to control the motor rotation of the peristaltic pump 1 based on the delivery command, and the peristaltic pump 1 drives the liquid in the infusion pipeline 3 to flow and transport.

[0045] Furthermore, the control module 400 also includes: The squeezing unit is used to control the valve of the stop valve 2 to squeeze the infusion pipeline 3 if the infusion state is in the infusion state, so that the stop valve 2 closes, terminates the infusion delivery, and generates a corresponding prompt message to be sent to the user interface.

If the system is in the startup state, determine the fluid delivery status of the fluid circuit system in the startup state; The startup status refers to whether the liquid circuit system is in a state that has been started and can be used, that is, whether it has been installed or not disassembled; by monitoring the motor status of the peristaltic pump or directly measuring the pressure and flow rate in the infusion tube, the current liquid delivery status is determined to be either a waiting state or a delivered state. Based on the infusion status, a control command is generated to drive the check valve on the fluid circuit system to close, and a corresponding prompt message is generated. If the liquid delivery state is in the waiting delivery state, a corresponding prompt message is generated, the user's closing command is identified, and the valve of the check valve is controlled to squeeze the delivery pipeline based on the closing command, so that the check valve is closed. If the liquid delivery status is "delivered", the valve controlling the stop valve will squeeze the delivery pipeline to close the stop valve, terminate the liquid delivery, and generate a corresponding prompt message to be sent to the user interface. After the stop valve is controlled to close, a sensor is used to detect whether the stop valve is fully compressed.

5. A system for peristaltic pump door status detection and fluid circuit control, characterized in that, include: The identification module is used to detect the opening event of the peristaltic pump door and, in response to the opening event, identify whether the current liquid circuit system is in the start-up state. The non-control module is used to prevent the stop valve on the liquid circuit system from closing if it is not in the start-up state; The judgment module is used to determine the infusion status of the fluid circuit system if it is in the startup state. The startup status refers to whether the liquid circuit system is in a state that has been started and can be used, that is, whether it has been installed or not disassembled; by monitoring the motor status of the peristaltic pump or directly measuring the pressure and flow rate in the infusion tube, the current liquid delivery status is determined to be either a waiting state or a delivered state. The control module is used to generate control commands based on the infusion status to drive the check valve on the fluid circuit system to perform a closing action and generate corresponding prompt information; If the liquid delivery state is in the waiting delivery state, a corresponding prompt message is generated, the user's closing command is identified, and the valve of the check valve is controlled to squeeze the delivery pipeline based on the closing command, so that the check valve is closed. If the liquid delivery status is "delivered", the valve controlling the stop valve will squeeze the delivery pipeline to close the stop valve, terminate the liquid delivery, and generate a corresponding prompt message to be sent to the user interface. After the stop valve is controlled to close, a sensor is used to detect whether the stop valve is fully compressed.
