Description

Technical Field

[0001] The present application relates to the field of interventional robot technology, and more specifically, to a method, system, device and medium for detecting the state of a peristaltic pump door and controlling a fluid path. Background Art

[0002] During existing interventional procedures, saline infusion is often required, and the status of the peristaltic pump door is crucial to the safety and reliability of the infusion process. If the peristaltic pump door is accidentally opened during the infusion process, blood may flow back into the infusion line, which will not only contaminate the remaining liquid medicine, but also cause unforeseen operational risks.

[0003] Some saline infusion devices currently on the market lack the ability to monitor the status of the peristaltic pump door in real time and are unable to take prompt action to reduce potential hazards when abnormal conditions occur.

[0004] Therefore, during the existing interventional operation, the use status of the peristaltic pump door cannot be monitored and controlled in time, resulting in an increased risk of liquid reflux, which needs to be solved urgently. Summary of the invention

[0005] The main purpose of this application is to provide a peristaltic pump door status detection and liquid circuit control method, system, equipment and medium, aiming to solve the problem that in the existing intervention process, the use status of the peristaltic pump door cannot be timely supervised and controlled, resulting in an increased risk of liquid reflux.

[0006] The first aspect of the present application provides a peristaltic pump door state detection and fluid circuit control method, comprising:

[0007] When the peristaltic pump door is detected to be open, it is identified whether the current liquid system is in the startup state;

[0008] If it is not in the start-up state, the liquid stop valve on the liquid circuit system is not closed;

[0009] If it is in the startup state, determining the infusion state of the liquid circuit system in the startup state;

[0010] Based on the infusion status, the liquid stop valve on the liquid circuit system is controlled to close, and corresponding prompt information is generated.

[0011] Furthermore, before the step of detecting that the peristaltic pump door is opened and identifying whether the current fluid circuit system is in the startup state, the following steps are included:

[0012] Detecting the closing state of the peristaltic pump door based on the sensor;

[0013] If the peristaltic pump door is detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is closed;

[0014] If the peristaltic pump door cannot be detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is open. Further, it is characterized in that the step of identifying whether the current fluid circuit system is in the startup state includes:

[0015] Determine whether the infusion pipeline of the current fluid system is in an installation or removal state;

[0016] If it is in the installation or removal state, it is determined to be not in the startup state;

[0017] If it is not in the installation or removal state, it is determined that the current fluid system is in the startup state.

[0018] Furthermore, it is characterized in that, if in the startup state, the step of determining the infusion state of the liquid circuit system in the startup state comprises:

[0019] Check whether the motor of the peristaltic pump is in a rotating state;

[0020] If it is in the rotating state, it is determined that the fluid system is in the infusion state;

[0021] If it is not in the rotating state, it is determined that the fluid system is in the state of waiting for infusion;

[0022] Or, detecting the fluid pressure or fluid flow in the infusion line based on a sensor;

[0023] If the fluid circuit pressure or fluid circuit flow rate is within a preset range, it is determined that the fluid circuit system is in a state of having been infused;

[0024] If the fluid circuit pressure or fluid circuit flow rate is not within a preset range, it is determined that the fluid circuit system is in a state ready for infusion.

[0025] Furthermore, the step of controlling the closing of the liquid stop valve on the liquid circuit system based on the infusion state and generating corresponding prompt information includes:

[0026] If the infusion state is a waiting infusion state, generating corresponding prompt information;

[0027] The closing instruction of the user is identified, and based on the closing instruction, the valve of the liquid stop valve is controlled to squeeze the infusion pipeline to close the liquid stop valve.

[0028] Furthermore, after the step of identifying the closing instruction of the user and controlling the valve of the liquid stop valve to squeeze the infusion pipeline based on the closing instruction to close the liquid stop valve, the method further comprises:

[0029] generating a preparatory delivery interface, and identifying a user's delivery instruction based on the preparatory delivery interface;

[0030] The motor of the peristaltic pump is controlled to rotate based on the delivery instruction, and the peristaltic pump drives the liquid in the infusion pipeline to flow and deliver.

[0031] Furthermore, the step of controlling the closing of the liquid stop valve on the liquid circuit system based on the infusion state and generating corresponding prompt information includes:

[0032] If the infusion state is the infusion state, the valve of the liquid stop valve is controlled to squeeze the infusion pipeline to close the liquid stop valve, terminate the liquid line transportation, and generate corresponding prompt information to be sent to the user interface.

[0033] The second aspect of the present application provides a system for peristaltic pump door state detection and fluid circuit control, comprising:

[0034] An identification module is used to identify whether the current fluid system is in a startup state when it is detected that the peristaltic pump door is opened;

[0035] A non-control module, used for not controlling the closing of the liquid stop valve on the liquid circuit system if it is not in the startup state;

[0036] A judgment module, used for judging the infusion state of the liquid circuit system in the startup state if it is in the startup state;

[0037] The control module is used to control the closing of the liquid stop valve on the liquid circuit system based on the infusion state and generate corresponding prompt information.

[0038] The third aspect of the present application proposes a computer device, including a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the steps of the method for peristaltic pump door status detection and liquid circuit control described in any one of the above are implemented.

[0039] A fourth aspect of the present application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method for peristaltic pump door state detection and fluid circuit control as described in any one of the above.

[0040] Beneficial effects:

[0041] The identification and control of the startup state and infusion state of the liquid system are processed separately to ensure that each link can operate efficiently and improve the overall performance of the system. Different control strategies are adopted according to different states to adapt to various usage scenarios and improve the applicability and flexibility of the system. Different judgments and control responses can be made based on the usage status of the liquid system, and the risk of liquid reflux in actual application scenarios can be accurately identified. Prompt information is generated at key operation nodes to notify users of the current device status, helping users to take corresponding measures in time, and improving the convenience and transparency of operations. By real-time detection of the opening and closing status of the peristaltic pump door, it can respond immediately when the pump door is opened to prevent liquid reflux and reduce operational risks during intervention.

[0050] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with those in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0051] Reference Figure 1 - Figure 2 , the embodiment of the present application provides a peristaltic pump door state detection and liquid circuit control method, including steps S1-S4:

[0052] S1, when the peristaltic pump door is detected to be open, identify whether the current liquid circuit system is in the startup state;

[0053] S2, if it is not in the start-up state, the liquid stop valve 2 on the liquid circuit system is not closed;

[0054] S3, if in the startup state, determining the infusion state of the liquid circuit system in the startup state;

[0055] S4. Based on the infusion status, the liquid stop valve 2 on the liquid circuit system is controlled to close, and corresponding prompt information is generated.

[0056] In this embodiment, the system first uses a sensor to detect the state of the peristaltic pump door. Other types of sensors such as infrared sensors, ultrasonic sensors, magnetic switches, proximity switches, etc. can be used to achieve the same function. The role of this step is to detect the state change of the pump door in time, which is crucial to ensure the safety of infusion. It can prevent safety accidents that may be caused by the unexpected opening of the pump door, such as liquid backflow, in advance.

[0057] When the system confirms that the peristaltic pump door is open, it will then determine whether the fluid system is in the startup state. The "startup state" here refers to whether the fluid system is in a state that has been started and can be used, that is, whether it has been installed or is not disassembled. If the system determines that it is not in the startup state (for example, the fluid system is being installed or disassembled), the closing operation of the stop valve 2 will not be performed. This decision logic is designed to avoid misoperation in the non-infusion state and reduce unnecessary equipment wear and energy consumption. In addition, such a design can also protect medical personnel from interference during maintenance or replacement operations. It improves the intelligence level of the system and user experience, while reducing the maintenance cost of the equipment.

[0058] Once it is confirmed that the fluid circuit system is in the startup state, the system will further check the current infusion state, that is, determine whether it is in the waiting for infusion or the infusion state. This can be done by monitoring the motor state of the peristaltic pump 1 or directly measuring the pressure and flow in the infusion tube. If the motor is running or the detected fluid circuit pressure and flow meet the preset conditions, it can be determined that the system is in the infusion process. On the contrary, if the motor stops running or the fluid circuit parameters do not meet the infusion conditions, the system is considered to be in the waiting for infusion state. This step helps the system to respond more accurately and ensure that appropriate measures are taken in different situations. The adaptability and safety of the system are enhanced, and it can effectively prevent dangerous situations such as liquid backflow under various working conditions.

[0059] Finally, according to the infusion status determined in the previous step, the system will take corresponding control measures. If the system is in the state of waiting for infusion, a prompt message will be generated to notify the user to close the pump door to ensure safe preparation before infusion. If the system is already in the state of infusion, the system will immediately close the stop valve 2, drive the valve of the stop valve 2 through the motor to squeeze the infusion tube to prevent the liquid from continuing to flow, and generate a warning message at the same time to remind medical staff through auditory and visual means. This series of actions quickly and accurately responds to the abnormal opening event of the pump door, greatly reducing potential risks. It can provide immediate fault handling capabilities, ensure the safety of the operation process, and help operators quickly locate problems.

[0060] In one embodiment, before the step of detecting that the peristaltic pump door is opened and identifying whether the current fluid circuit system is in a startup state, the step includes:

[0061] S10, detecting a closed state of a peristaltic pump door based on a sensor;

[0062] S11, if the peristaltic pump door is detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is closed;

[0063] S12: If the peristaltic pump door cannot be detected within the preset detection range of the sensor, it is determined that the peristaltic pump door is open.

[0064] In this embodiment, the system needs to detect the closed state of the peristaltic pump door through the pump door detection device 4, that is, the closed state of the pump door is detected by a sensor that detects the pump door, such as a photoelectric sensor, a proximity switch or a magnetic switch. The photoelectric sensor is installed at the closed position of the pump door. When the pump door is closed, the light of the photoelectric sensor is blocked and it is determined to be in a closed state; when the pump door is opened, the light passes through and it is determined to be in an open state. The proximity switch is also installed at the closed position of the pump door. When the pump door is closed, the proximity switch detects an object and it is determined to be in a closed state; when the pump door is opened, the proximity switch cannot detect an object and it is determined to be in an open state. The magnetic switch installs a small magnet on the pump door and installs the magnetic switch at a fixed position. When the pump door is closed, the magnetic switch detects a magnetic field and it is determined to be in a closed state; when the pump door is opened, the magnetic switch cannot detect a magnetic field and it is determined to be in an open state. When the system starts, an initialization test is performed to determine the initial state of the pump door, and then the state of the pump door is continuously detected during the operation of the system to ensure that the opening and closing of the pump door is mastered in real time. By using or combining these sensors, the system can detect the status of the pump door with high accuracy, ensuring the safety and reliability of the infusion process.

[0065] In one embodiment, the step of identifying whether the current fluid circuit system is in a startup state includes:

[0066] S20, determining whether the infusion pipeline 3 of the current fluid system is in an installation or removal state;

[0067] S21, if it is in the installation or removal state, it is determined to be not in the startup state;

[0068] If it is not in the installation or removal state, it is determined that the current fluid system is in the startup state.

[0069] In this embodiment, it is determined whether the infusion pipeline 3 of the current liquid circuit system is in an installation or removal state. This is because during the installation or removal process, the liquid circuit system should not perform any infusion-related control operations to avoid interfering with the operation of medical staff or causing unnecessary equipment damage. The specific judgment method may include the following aspects: 1. Physical sensor detection: Sensors, such as proximity switches or photoelectric sensors, can be installed at the connection points of the liquid circuit system to detect whether the pipeline is connected in place. If the sensor detects that the pipeline is not connected or is being connected, the system will judge it as an installation or removal state. 2. Manual operation confirmation: A manual operation button or interface is provided for manual confirmation by medical staff when starting to install or remove the pipeline, which can ensure that the system's judgment is more accurate.

[0070] If the system determines that the infusion line 3 of the current fluid system is in the installation or removal state, it will determine that the fluid system is not in the startup state. At this time, the system will not perform any control operations related to infusion, such as closing the liquid stop valve 2. Specific technical implementations may include: setting control logic in the software, disabling all infusion-related control functions when the installation or removal state is detected, to ensure that the system will not be misoperated. At the same time, a clear prompt message is displayed on the user interface to inform medical staff that the current system is in the installation or removal state to avoid misoperation.

[0071] In one embodiment, if the system is in a startup state, the step of determining the infusion state of the fluid system in the startup state includes:

[0072] S30, detecting whether the motor of the peristaltic pump 1 is in a rotating state;

[0073] S31, if it is in the rotating state, it is determined that the liquid circuit system is in the infusion state;

[0074] S32, if it is not in the rotating state, it is determined that the liquid circuit system is in the state of waiting for infusion;

[0075] S33, or, detecting the liquid pressure or liquid flow in the infusion pipeline 3 based on the sensor;

[0076] S34, if the fluid circuit pressure or fluid circuit flow rate is within a preset range, it is determined that the fluid circuit system is in a state of infusion;

[0077] S35. If the fluid circuit pressure or fluid circuit flow rate is not within a preset range, it is determined that the fluid circuit system is in a state ready for infusion.

[0078] In this embodiment, it is detected whether the motor of the peristaltic pump 1 is in a rotating state. The rotation state of the motor can directly reflect whether the infusion system is working. The specific detection method may include: judging whether the motor is rotating by detecting the change in the current of the motor. When the motor rotates, the current will fluctuate significantly, while the current is relatively stable when stationary. Or an encoder is installed on the motor, and the rotation state of the motor is judged by the pulse signal 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 in a rotating state, it will be determined that the liquid circuit system is in an infused state. This means that the infusion process is in progress, and the system needs to take corresponding control measures to keep the pump door closed normally. If the system detects that the motor of the peristaltic pump 1 is not in a rotating state, it will be determined that the liquid circuit system is in a waiting state for infusion. This means that the infusion process has not yet started, and the system needs to take corresponding control measures, such as prompting the user to close the pump door to ensure that the preparations before infusion are completed.

[0079] Alternatively, a pressure sensor may be installed on the infusion line 3 to detect changes in pressure in the line. When the pressure is within a preset range, the system is determined to be in an infusion state; otherwise, the system is determined to be in an infusion-waiting state. Alternatively, a flow sensor may be installed on the infusion line 3 to detect changes in flow in the line. When the flow is within a preset range, the system is determined to be in an infusion state; otherwise, the system is determined to be in an infusion-waiting state. If the system detects that the liquid line pressure or liquid line flow in the infusion line 3 is within a preset range, it will be determined that the liquid line system is in an infusion state. This means that the infusion process is in progress, and the system needs to take corresponding pump gate control measures.

[0080] In one embodiment, the step of controlling the liquid stop valve 2 on the liquid circuit system to close based on the infusion state and generating corresponding prompt information includes:

[0081] S40, if the infusion state is a waiting infusion state, generating corresponding prompt information;

[0082] S41, identifying a closing instruction from the user, and based on the closing instruction, controlling the valve of the liquid stop valve 2 to squeeze the infusion pipeline 3, so that the liquid stop valve 2 is closed.

[0083] In this embodiment, it has been determined that the liquid circuit system is in a state of waiting for infusion. This means that the infusion process has not yet started, but the peristaltic pump door is accidentally opened, and there is a potential safety risk. In order to ensure safe preparation before infusion, the system needs to generate corresponding prompt information to inform the user of the current state and the required actions. Specific technical implementations may include: 1. User interface prompts: Display clear prompt information on the display screen of the device, such as: "The peristaltic pump door is not closed, please close the pump door to continue operation." At the same time, a sound prompt can be issued through a built-in speaker or buzzer to remind medical staff to pay attention to the current state, or a visual warning can be provided by flashing or constantly lighting an LED light or other indicator light. After generating the prompt information, the system starts a program to receive the user's closing instruction and actively identifies the user's closing instruction. When the user confirms to close the peristaltic pump door on the interface, the system recognizes the user's closing instruction and takes corresponding control measures to close the liquid stop valve 2. Specific technical implementations may include: providing a confirmation button on the user interface, and the medical staff clicks the button after closing the pump door, and the system recognizes the closing instruction. Once the system recognizes the user's closing instruction, it will perform the following operations: start the motor to drive the valve of the liquid stop valve 2 to move inward, so that the valve of the liquid stop valve 2 is loosened from the infusion pipeline 3, and the fluid path is restored to be unobstructed. The current status is updated on the user interface, and a prompt message "The peristaltic pump door is closed, and the infusion can begin" is displayed. The main function of this step is that after the user confirms that the pump door is closed, the system can respond in time and restore the normal state of the fluid path to ensure the safety of the infusion process. The technical effect is to improve the automation level and reliability of the system, reduce human operation errors, and ensure the smooth progress of the infusion process.

[0084] In one embodiment, after the step of identifying the closing instruction of the user and controlling the valve of the liquid stop valve 2 to squeeze the infusion pipeline 3 based on the closing instruction to close the liquid stop valve 2, the method includes:

[0085] S50, generating a preparatory delivery interface, and identifying a user's delivery instruction based on the preparatory delivery interface;

[0086] S51 . Based on the delivery instruction, the motor of the peristaltic pump 1 is controlled to rotate, and the peristaltic pump 1 drives the liquid in the infusion pipeline 3 to flow and deliver.

[0087] In this embodiment, after the user's closing instruction is recognized and the liquid stop valve 2 is controlled to close, a preparatory delivery interface is then generated, and the user's delivery instruction is recognized based on the interface. The specific technical implementation may include: generating a preparatory delivery interface on the display screen of the device, which contains infusion setting options, such as infusion rate, total infusion volume, etc. A confirmation button is provided on the preparatory delivery interface, and the user clicks the button after setting the infusion parameters, and the system recognizes the delivery instruction. The user selects the infusion parameters and confirms the delivery instruction through the touch screen, and physical buttons are set on the device, and the user selects the infusion parameters and confirms the delivery instruction through the buttons. Furthermore, a voice recognition function can be integrated, and the user sets the infusion parameters and confirms the delivery instruction through voice commands.

[0088] After the system recognizes the user's delivery instruction, it controls the motor of the peristaltic pump 1 to rotate, driving the liquid in the infusion pipeline 3 to flow and deliver. A stepper motor or servo motor is used to accurately control the rotation angle and speed of the peristaltic pump 1 to ensure the accuracy of the infusion rate.

[0089] In one embodiment, the step of controlling the closing of the liquid stop valve 2 on the liquid circuit system based on the infusion state and generating corresponding prompt information includes:

[0090] S60, if the infusion state is the infusion state, control the valve of the liquid stop valve 2 to squeeze the infusion pipeline 3 to close the liquid stop valve 2, terminate the liquid line transportation, and generate corresponding prompt information to send to the user interface.

[0091] In this embodiment, when the system determines that the infusion state is the infusion state, if the pump door is detected to be open, it is necessary to start the automatic control pump door closing program to ensure the safety of the infusion process. At this time, the motor is directly started to drive the valve of the stop valve 2 to move toward the infusion pipeline 3, so that the valve of the stop valve 2 squeezes the infusion pipeline 3 and closes the stop valve 2. The sensor detects whether the stop valve 2 is squeezed in place to ensure that the stop valve 2 is completely closed. For example, the optical coupling sensor detects whether the stop valve 2 or other components moving with the stop valve 2 are detected within the specified range, so as to determine whether the stop valve 2 moves a sufficient length so that the infusion pipeline 3 is completely squeezed and the liquid cannot flow. At the same time, the motor of the peristaltic pump 1 can be stopped to ensure that the infusion pump no longer rotates and the liquid line delivery is terminated. A clear prompt message is displayed on the display screen of the device, for example: "The peristaltic pump door has been automatically closed, the infusion has been terminated, please check the operating table." At the same time, a sound prompt is issued through the built-in speaker or buzzer to remind medical staff to pay attention to the current state or a visual warning is provided by the flashing or constant lighting of the LED light or other indicator light.
