Description

Technical Field

[0001] The present application relates to the field of medical device technology, and more specifically, to a pneumoperitoneum machine control system, method, device, electronic equipment, and storage medium. Background Art

[0002] The use of insufflators is crucial in medical surgery, broadening the doctor's field of vision and operating space by establishing pneumoperitoneum. However, the issue of abdominal pressure control by insufflators cannot be ignored. If the safety and stability of abdominal pressure cannot be ensured, frequent high-pressure conditions may cause serious complications such as pneumothorax, posing a threat to the patient's health. This requires the insufflator to have precise pressure control capabilities, capable of real-time monitoring and adjusting abdominal pressure to maintain it within a safe range. Pressure stabilization control is closely related to multiple modules, including exhaust control and flow control, and the coordination between these modules directly affects the pressure stabilization effect.

[0003] Some existing pneumoperitoneum control systems usually use simple switch control or linear control methods, which are difficult to cope with complex pressure changes. When faced with sudden pressure fluctuations, these systems often do not respond quickly and accurately, which can easily cause excessive fluctuations in abdominal pressure.

[0004] There is currently no effective technical solution to the above problems. Summary of the Invention

[0005] The purpose of this application is to provide a pneumoperitoneum control system, method, device, electronic equipment and storage medium, which introduces a state machine for module control to achieve rapid response, precise control and flexible adaptation of abdominal cavity pressure.

[0006] In a first aspect, the present application provides a pneumoperitoneum control system for controlling the pneumoperitoneum to establish pneumoperitoneum, wherein the pneumoperitoneum controls gas supply based on a proportional valve and exhaust based on an exhaust valve, and wherein the system controls the operation of the proportional valve based on a proportional valve state machine and controls the operation of the exhaust valve based on an exhaust valve state machine;

[0007] The states of the proportional valve state machine include a waiting state for blowing, a blowing state, and a waiting state after blowing, which are switched in a cycle in sequence;

[0008] The exhaust valve state machine includes the exhaust closed state, exhaust open state, and exhaust waiting state, which are switched in sequence;

[0009] The exhaust valve state machine switches from the exhaust closed state to the exhaust open state when the abdominal cavity pressure is too high.

[0010] The pneumoperitoneum control system of the present application realizes fine control of the gas supply and exhaust processes by introducing a proportional valve state machine and an exhaust valve state machine. The control process simplifies the control logic, enables rapid response, precise control and flexible adaptation of the abdominal cavity pressure, effectively prevents frequent high-pressure conditions, and thus improves the safety and efficiency of the operation; secondly, the introduction of the state machine enables doctors and technicians to understand the working status of the pneumoperitoneum more intuitively, helps to discover potential problems in a timely manner, and effectively improves the observability of the system. This high observability not only improves the safety of the system, but also provides valuable data support for subsequent optimization and improvement.

[0011] The pneumoperitoneum machine control system, wherein the insufflation state of the proportional valve state machine and the exhaust opening state of the exhaust valve state machine are mutually exclusive;

[0012] When the abdominal cavity pressure is too high, the proportional valve state machine switches and locks to the waiting for insufflation state.

[0013] In this example, the proportional valve state machine switches and locks into the waiting state for insufflation when the intra-abdominal pressure is too high. This feature can immediately stop the insufflation operation when excessive intra-abdominal pressure is detected, preventing the intra-abdominal pressure from further increasing, thereby protecting the patient's safety.

[0014] The pneumoperitoneum machine control system, wherein the exhaust valve state machine switches from the exhaust open state to the exhaust waiting state after the abdominal cavity pressure returns to normal, and switches from the exhaust waiting state to the exhaust closed state after the abdominal cavity pressure stabilizes, and the proportional valve state machine is unlocked after the abdominal cavity pressure stabilizes.

[0015] The multi-stage control strategy of the present application can respond to pressure abnormalities more quickly and quickly resume normal operation after the pressure is restored. This rapid response and recovery capability is particularly important in emergency situations and can minimize the interruption time of surgery. In terms of safety, the present application greatly reduces the risk of sudden pressure changes or sustained high pressure through precise state control and multiple judgment mechanisms, which not only improves the safety of patients, but also provides doctors with a more stable surgical environment. In terms of system adaptability, the technical solution of the present application uses adjustable parameters (such as pressure thresholds, time thresholds, etc.) to enable the system to be flexibly adjusted according to the needs of different patients and different types of surgeries, thereby improving the versatility and adaptability of the system.

[0016] In the pneumoperitoneum machine control system, the state switching timing of the proportional valve state machine is performed when the exhaust valve state machine is in the exhaust closed state.

[0017] In a second aspect, the present application further provides a method for controlling an insufflator, which is applied to the insufflator control system provided in the first aspect, and the method comprises the following steps:

[0018] Adjusting the states of the proportional valve state machine and the exhaust valve state machine so that the abdominal cavity pressure information is stabilized within a target range, the step of adjusting the states of the proportional valve state machine and the exhaust valve state machine comprising:

[0019] When the exhaust valve state machine is in the exhaust closed state, the proportional valve state machine is controlled to cyclically switch in the waiting state for insufflation, the insufflation state, and the waiting state after insufflation to establish pneumoperitoneum;

[0020] During the process of establishing pneumoperitoneum, abdominal cavity pressure information is acquired in real time, and when the abdominal cavity pressure information is greater than a first preset air pressure, the proportional valve state machine is controlled to switch and lock to the waiting for insufflation state, and the exhaust valve state machine is controlled to switch from the exhaust closed state to the exhaust open state to perform abdominal cavity pressure relief, and the first preset air pressure is greater than or equal to the upper limit of the target range;

[0021] During the abdominal pressure relief process, when the abdominal pressure information is less than the second preset air pressure, the exhaust valve state machine is controlled to switch from the exhaust open state to the exhaust waiting state, and after the abdominal pressure stabilizes, the exhaust valve state machine is simultaneously controlled to switch from the exhaust waiting state to the exhaust closed state and the proportional valve state machine is controlled to be unlocked, and the second preset air pressure is less than or equal to the upper limit value of the target range.

[0022] The insufflator control method of the present application realizes the intelligent and precise control of the insufflator by introducing the concept of a state machine. The proportional valve state machine switches cyclically between three states: waiting for air blowing, during air blowing, and waiting after air blowing. This design enables the system to flexibly adjust the air supply according to actual needs, avoiding the problems of excessive air supply or insufficient air supply that may occur in traditional control methods; secondly, a dual-threshold control strategy is introduced, which can adaptively adjust the exhaust and pressure relief of the overshooting abdominal pressure, effectively preventing the potential risks caused by excessive abdominal pressure, and when the pressure drops below the second preset air pressure, the system will not resume air supply immediately, but enter a stable waiting stage, which can further avoid frequent switching caused by pressure fluctuations and improve the stability of the system.

[0023] The method for controlling the pneumoperitoneum machine further comprises the following steps:

[0024] Draw and output the abdominal cavity pressure information, change curves of the states of the proportional valve state machine and the exhaust valve state machine with respect to time.

[0025] In the described method for controlling an insufflator, the process of cyclically switching the control proportional valve state machine among the waiting state for insufflation, the insufflation state, and the waiting state after insufflation is performed based on a preset switching interval.

[0026] In a third aspect, the present application further provides a pneumoperitoneum control device, which is applied to the pneumoperitoneum control system provided in the first aspect, and the device comprises:

[0027] an adjusting module, configured to adjust the states of the proportional valve state machine and the exhaust valve state machine so that the abdominal cavity pressure information is stabilized within a target range;

[0028] The adjustment module includes:

[0029] A pneumoperitoneum establishment module, configured to control the proportional valve state machine to cyclically switch among a waiting state for insufflation, a state during insufflation, and a waiting state after insufflation to establish pneumoperitoneum when the exhaust valve state machine is in an exhaust closed state;

[0030] a pressure relief trigger module, configured to obtain abdominal pressure information in real time during the process of establishing pneumoperitoneum, and control the proportional valve state machine to switch and lock to the waiting for insufflation state, and control the exhaust valve state machine to switch from the exhaust closed state to the exhaust open state to perform abdominal pressure relief when the abdominal pressure information is greater than a first preset pressure, wherein the first preset pressure is greater than or equal to the upper limit of the target range;

[0031] The pressure relief and stabilization module is used to control the exhaust valve state machine to switch from the exhaust open state to the exhaust waiting state when the abdominal pressure information is less than a second preset air pressure during the abdominal pressure relief process, and to control the exhaust valve state machine to switch from the exhaust waiting state to the exhaust closed state and control the proportional valve state machine to unlock after the abdominal pressure stabilizes, and the second preset air pressure is less than or equal to the upper limit value of the target range.

[0032] The insufflator control device of the present application realizes the intelligent and precise control of the insufflator by introducing the concept of a state machine. The proportional valve state machine switches cyclically between three states: waiting for air blowing, during air blowing, and waiting after air blowing. This design enables the system to flexibly adjust the air supply according to actual needs, avoiding the problems of excessive or insufficient air supply that may occur in traditional control methods; secondly, a dual-threshold control strategy is introduced, which can adaptively adjust the exhaust and pressure relief of the overshooting abdominal pressure, effectively preventing the potential risks that may be caused by excessive abdominal pressure, and when the pressure drops below the second preset air pressure, the system will not resume air supply immediately, but enter a stable waiting stage, which can further avoid frequent switching caused by pressure fluctuations and improve the stability of the system.

[0033] In a fourth aspect, the present application also provides an electronic device comprising a processor and a memory, wherein the memory stores computer-readable instructions. When the computer-readable instructions are executed by the processor, the steps in the method provided in the second aspect above are executed.

[0034] In a fifth aspect, the present application further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, runs the steps of the method provided in the second aspect above.

[0035] From the above, it can be seen that the present application provides a pneumoperitoneum control system, method, device, electronic device and storage medium, wherein the pneumoperitoneum control system realizes fine control of the gas supply and exhaust process by introducing a proportional valve state machine and an exhaust valve state machine. The control process simplifies the control logic, enables the abdominal cavity pressure to respond quickly, be precisely controlled and flexibly adapted, effectively prevents the frequent occurrence of high-pressure conditions, thereby improving the safety and efficiency of the operation; secondly, the introduction of the state machine enables doctors and technicians to understand the working status of the pneumoperitoneum more intuitively, helps to discover potential problems in a timely manner, and effectively improves the observability of the system. This high observability not only improves the safety of the system, but also provides valuable data support for subsequent optimization and improvement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0045] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0046] First, please refer to Figure 1 and Figure 2 Some embodiments of the present application provide a pneumoperitoneum control system for controlling the pneumoperitoneum to establish pneumoperitoneum. The pneumoperitoneum controls gas supply based on a proportional valve and exhaust based on an exhaust valve. The system controls the operation of the proportional valve based on a proportional valve state machine and controls the operation of the exhaust valve based on an exhaust valve state machine.

[0047] The states of the proportional valve state machine include the waiting state for blowing, the blowing state, and the waiting state after blowing, which are switched in a cycle in sequence;

[0048] The exhaust valve state machine includes the exhaust closed state, exhaust open state, and exhaust waiting state, which are switched in sequence;

[0049] The exhaust valve state machine switches from the exhaust closed state to the exhaust open state when the abdominal cavity pressure is too high.

[0050] Specifically, if Figure 1As shown, the pneumoperitoneum machine includes an air inlet 101, an air supply pipe 102 connected to the air inlet 101 at one end, an insufflation tube 103 connected to the other end of the air supply pipe 102, a proportional valve 104 and an exhaust valve 105 arranged on the air supply pipe 102, and a microcontroller 106 electrically connected to the proportional valve 104 and the exhaust valve 105; wherein, the air inlet 101 is generally connected to an air supply component (not shown in the figure), such as a carbon dioxide air supply component; in this embodiment, the proportional valve 104 is opened to connect the air supply component with the insufflation tube to output gas to the patient to establish pneumoperitoneum, and changing the opening of the proportional valve 104 can adjust the output flow of the gas, and closing the proportional valve 104 and opening the exhaust valve 105 can allow the gas in the patient's abdominal cavity to flow back to the exhaust valve 105 for discharge to achieve pressure relief.

[0051] More specifically, since the air pressure in the pneumoperitoneum tube is almost consistent with the abdominal cavity pressure during the process of outputting gas to establish pneumoperitoneum, in the embodiment of the present application, a pressure sensor 107 is also provided on the air supply pipe 102 for obtaining the air pressure in the tube and obtaining the abdominal cavity pressure through the air pressure in the tube; in other embodiments, the pressure sensor 107 can also be set on the pneumoperitoneum tube 103.

[0052] More specifically, the state machine is composed of a state register and a combinational logic circuit, and can transfer states according to a pre-set state based on a control signal. It is a control center that coordinates related signal actions and completes specific operations. In the embodiment of the present application, the proportional valve state machine and the exhaust valve state machine are actually 106 components of the microcontroller, that is, the pneumoperitoneum machine control system in the embodiment of the present application is based on two types of state machines constructed in the microcontroller to realize the control of the proportional valve and the exhaust valve to adaptively adjust the abdominal cavity pressure.

[0053] More specifically, in traditional pressure control methods, pneumoperitoneum machines generally use a PID control valve method. PID control can be adjusted according to the pressure error, but when faced with rapidly changing abdominal pressure, there may be a response lag problem. In addition, PID control requires complex parameter tuning and is difficult to adapt to different patients and surgical conditions. However, for the pneumoperitoneum control system, pressure control is essentially a discrete event, and its behavior can be described by a finite state machine. Therefore, the embodiment of the present application proposes a pneumoperitoneum control system that controls changes in abdominal pressure based on a state machine. By controlling the operation of the proportional valve based on a proportional valve state machine and controlling the operation of the exhaust valve based on an exhaust valve state machine, adaptive and efficient regulation of abdominal pressure is achieved.

[0054] More specifically, the proportional valve state machine consists of three states: Waiting for Blow, Blowing, and Waiting After Blowing. These three states cycle through each other, enabling precise control of the airflow process. The Waiting for Blow state allows the system to perform necessary preparations and checks before commencing airflow; the Blowing state corresponds to the actual airflow operation; and the Waiting After Blow state provides a buffer period for the system to achieve stable intra-abdominal pressure after each round of airflow, allowing for evaluation of the airflow effect and preparation for the next operation. The proportional valve is closed in the Waiting for Blow and Waiting After Blow states, and open in the Blowing state.

[0055] More specifically, the pneumoperitoneum control system of the embodiment of the present application establishes pneumoperitoneum by cyclically switching between the waiting for blowing state, the blowing state and the waiting state after blowing, wherein a switching cycle consisting of the waiting for blowing state, the blowing state and the waiting state after blowing constitutes an inflation behavior. In this inflation behavior, the waiting for blowing state belongs to the pre-start state of the proportional valve in the pneumoperitoneum machine, and the blowing state belongs to the formal inflation state of the pneumoperitoneum machine (the open state of the proportional valve). After the inflation of this inflation behavior is completed, the gas in the abdominal cavity will cause a short-term fluctuation in air pressure due to inertia after the proportional valve is closed. Therefore, after the inflation is completed, it is necessary to first switch to the waiting state after blowing to stabilize the abdominal cavity pressure, and then execute the next inflation behavior to avoid air pressure fluctuations affecting air pressure monitoring, and ensure that the inflation behavior can be carried out in a stable and orderly manner, so that the abdominal cavity pressure can be steadily adjusted to improve patient comfort.

[0056] More specifically, the exhaust valve state machine also includes three states: exhaust closed state (Exhaust OFF), exhaust open state (Exhaust ON) and exhaust waiting state (Exhaust Wait). This design enables the system to accurately control the exhaust process; when exhaust pressure relief is not required, the exhaust valve state machine is always in the exhaust closed state. The exhaust open state corresponds to the actual exhaust pressure relief operation, which is executed at the time node when the abdominal pressure is too high; the exhaust waiting state provides a buffer period for the system exhaust pressure relief, so that the abdominal pressure can reach stability after the exhaust pressure relief behavior, so as to evaluate the exhaust pressure relief effect and prepare for the next operation; among them, in the exhaust closed state and the exhaust waiting state, the exhaust valve is in the closed state, and in the exhaust open state, the exhaust valve is in the open state.

[0057] More specifically, when the abdominal pressure is too high, the exhaust valve state machine can quickly switch from the exhaust closed state to the exhaust open state to achieve rapid pressure relief; after the exhaust valve is closed, the gas in the abdominal cavity will cause short-term fluctuations in air pressure due to inertia. Therefore, after the exhaust is completed, it is necessary to switch to the post-exhaust waiting state to stabilize the abdominal pressure before executing the next step to avoid air pressure fluctuations affecting air pressure monitoring and ensure that the exhaust behavior can be carried out stably and orderly, so that the abdominal pressure can be smoothly adjusted to improve patient comfort.

[0058] More specifically, the coordinated operation of the proportional valve state machine and the exhaust valve state machine is the core of this system. When intra-abdominal pressure is normal, the proportional valve state machine dominates the control process, intermittently executing inflation by cyclically switching states to establish pneumoperitoneum and maintain stable intra-abdominal pressure. If excessive pressure is detected, the exhaust valve state machine immediately intervenes, opening the exhaust valve to relieve pressure. This collaborative mechanism ensures that the system can quickly respond to pressure changes and effectively prevent the occurrence of high-pressure conditions.

[0059] More specifically, in each round of inflation, the switching of the proportional valve state machine can be performed based on preset time intervals. For example, the waiting state for inflation may last for 1-2 seconds, the inflation state lasts for 3-5 seconds, and the waiting state after inflation lasts for 2-3 seconds. These time intervals can be adjusted according to surgical requirements and patient conditions.

[0060] More specifically, the state machine-based pressure control approach offers several advantages: First, it simplifies control logic, making system behavior more predictable and controllable. Second, the discrete nature of the state machine enables the system to quickly respond to pressure changes, effectively preventing the occurrence of high-pressure conditions. Third, by adjusting the conditions and time intervals for state switching, the system can flexibly adapt to different surgical needs and patient conditions. Finally, the state machine's state switching characteristics improve the system's observability, facilitate the timely detection and handling of abnormal situations, and enhance the system's safety and reliability.

[0061] The pneumoperitoneum machine control system of the embodiment of the present application achieves fine control of the gas supply and exhaust processes by introducing a proportional valve state machine and an exhaust valve state machine. This control process simplifies the control logic, enables rapid response, precise control and flexible adaptation of the abdominal cavity pressure, effectively prevents frequent high-pressure conditions, and thus improves the safety and efficiency of the operation; secondly, the introduction of the state machine enables doctors and technicians to understand the working status of the pneumoperitoneum machine more intuitively, helps to discover potential problems in a timely manner, and effectively improves the observability of the system. This high observability not only improves the safety of the system, but also provides valuable data support for subsequent optimization and improvement.

[0062] In some preferred embodiments, the blowing state of the proportional valve state machine and the exhaust opening state of the exhaust valve state machine are mutually exclusive;

[0063] When the abdominal cavity pressure is too high, the proportional valve state machine switches and locks to the waiting for insufflation state.

[0064] Specifically, the blowing state of the proportional valve state machine and the exhaust opening state of the exhaust valve state machine are mutually exclusive, which means that the system will not perform blowing and exhaust operations at the same time, which can effectively avoid operational conflicts and help to control the abdominal pressure more accurately; the proportional valve state machine switches and locks to the waiting for blowing state when the abdominal pressure is too high. This feature can immediately stop the blowing operation when the abdominal pressure is detected to be too high, preventing the abdominal pressure from further increasing, thereby protecting the patient's safety.

[0065] More specifically, when intra-abdominal pressure becomes excessive, the system immediately stops insufflation and locks the proportional valve state machine, while simultaneously allowing the exhaust valve to open for pressure relief. This effectively prevents continued increases in intra-abdominal pressure and allows for rapid pressure reduction when needed, enhancing system safety and reliability. Furthermore, the mutually exclusive design and locking mechanism of the state machine enable the system to rapidly switch between insufflation and exhaust operations, more precisely controlling intra-abdominal pressure and keeping it within the target range.

[0066] More specifically, in an embodiment of the present application, the mutual exclusion design of the proportional valve state machine and the exhaust valve state machine can be achieved in a variety of ways, such as using a mutual exclusion lock mechanism to associate them. When the proportional valve state machine enters the blowing state, the system will lock the exhaust valve state machine to prevent it from entering the exhaust-on state; similarly, when the exhaust valve state machine enters the exhaust-on state, the system will lock the proportional valve state machine to prevent it from entering the blowing state. For example, mutual exclusion can be achieved through state checking and switching logic. Before each state switch, the system will check the current state of the other state machine and allow switching only when the mutual exclusion condition is met.

[0067] More specifically, the design of the proportional valve state machine switching and locking to the waiting for insufflation state when the abdominal pressure is too high can also be implemented in multiple ways: for example, setting a pressure threshold, and immediately triggering the state switching and locking operation when it is detected that the abdominal pressure exceeds the threshold; or judging by the pressure change rate, when the pressure rise rate exceeds the preset value, triggering switching and locking; in the embodiment of the present application, the former is preferred.

[0068] It should be noted that the proportional valve state machine is switched and locked to the waiting for air blowing state, which means that the proportional valve state machine cannot switch states after switching to the waiting for air blowing state, and the regular cyclic switching process must be performed after the unlocking conditions are met and the unlocking is completed.

[0069] It should be noted that when the abdominal cavity pressure is too high, the exhaust valve state machine will switch to the exhaust open state to exhaust and relieve pressure. The switching timing may be later than or synchronized with the timing when the proportional valve state machine switches to the waiting for insufflation state.

[0070] It should be noted that, based on the above content, when the proportional valve state machine is in the waiting state for blowing, the abdominal pressure must be in a relatively stable state, and excessive abdominal pressure only occurs when the proportional valve state machine is in the blowing state and the waiting state after blowing; when the proportional valve state machine is in the blowing state, if excessive abdominal pressure occurs, the proportional valve state machine can directly switch to the waiting state for blowing and then lock the state, or it can first switch to the waiting state after blowing and then switch to the waiting state for blowing and then lock the state. In actual operation, the waiting state after blowing takes a shorter time, and in order to ensure the stable state operation timing of the proportional valve state machine, the switching behavior of the proportional valve state machine is preferably the latter.

[0071] In some preferred embodiments, the exhaust valve state machine switches from the exhaust open state to the exhaust waiting state after the abdominal cavity pressure returns to normal, and switches from the exhaust waiting state to the exhaust closed state after the abdominal cavity pressure stabilizes, and the proportional valve state machine is unlocked after the abdominal cavity pressure stabilizes.

[0072] Specifically, the process of the exhaust valve state machine switching from the exhaust open state to the exhaust waiting state after the abdominal pressure returns to normal can be achieved by setting a pressure threshold. For example, when the abdominal pressure drops below a pressure threshold, the exhaust valve state machine switches from the exhaust open state to the exhaust waiting state; the exhaust valve state machine switching from the exhaust waiting state to the exhaust closed state can also be triggered by setting a time threshold or by setting a pressure deviation. For example, by setting a time threshold, it is believed that the abdominal gas will inevitably reach a stable state after the time threshold. For example, by setting a pressure deviation threshold, if the maximum deviation of the abdominal pressure within a certain period of time is less than the pressure deviation threshold, the abdominal pressure is considered to be stable. For example, by setting a pressure deviation percentage threshold, if the maximum deviation percentage of the abdominal pressure within a period of time is less than the pressure deviation percentage threshold, the abdominal pressure is considered to be stable.

[0073] More specifically, the unlocking of the proportional valve state machine can be performed synchronously with the exhaust valve state machine switching to the exhaust closed state, or it can be delayed for a period of time after the exhaust valve state machine switches to the exhaust closed state. The latter can ensure that the system has enough time to complete the state transition.

[0074] More specifically, in this embodiment, when intra-abdominal pressure is excessively high, the exhaust valve opens to relieve pressure. As pressure decreases, the exhaust valve state machine enters the post-exhaust waiting state, closing the exhaust valve. This stage acts as a buffer, preventing a sudden pressure surge. Only when the pressure stabilizes does the exhaust valve fully close (the exhaust valve state machine enters the exhaust closed state), and the proportional valve state machine simultaneously unlocks, allowing the system to resume normal pneumoperitoneum establishment. This phased control strategy ensures safety while improving system response speed and stability, ensuring that the system resumes normal operation at the appropriate time and avoiding unnecessary pressure fluctuations.

[0075] It should be noted that after the proportional valve state machine is unlocked, the proportional valve state machine re-enters the normal pneumoperitoneum establishment cycle.

[0076] More specifically, in terms of system response speed, the multi-stage control strategy of the present application can respond to pressure abnormalities more quickly and quickly resume normal operation after the pressure is restored. This rapid response and recovery capability is particularly important in emergency situations and can minimize the interruption time of surgery; in terms of safety, the present application greatly reduces the risk of sudden pressure changes or sustained high pressure through precise state control and multiple judgment mechanisms, which not only improves the safety of patients, but also provides doctors with a more stable surgical environment; in terms of system adaptability, the technical solution of the present application uses adjustable parameters (such as pressure thresholds, time thresholds, etc.) to enable the system to be flexibly adjusted according to the needs of different patients and different types of surgeries, thereby improving the versatility and adaptability of the system.

[0077] In some preferred embodiments, the state switching timing of the proportional valve state machine is performed when the exhaust valve state machine is in the exhaust closed state.

[0078] Specifically, in an embodiment of the present application, the state switching timing of the proportional valve state machine can be achieved in a variety of ways. For example, one possible implementation method is to set an exhaust valve state detection module, which monitors the on-off state of the exhaust valve in real time. Only when it is detected that the exhaust valve is in a closed state is the proportional valve state machine allowed to switch states. For another example, another implementation method is to set a state switching condition in the control logic, and only when the exhaust valve state machine is in an exhaust closed state, the switching instruction of the proportional valve state machine is executed; during the entire switching process of the proportional valve, the state switching of the proportional valve state machine is completed in the exhaust valve closed state, achieving precise coordination between the proportional valve and the exhaust valve, reducing possible conflicts and errors during state switching, improving the overall reliability and safety of the system, and avoiding pressure fluctuations that may be caused by changing the state of the proportional valve during the exhaust process.

[0079] Second, please refer to Figure 3 and Figure 4Some embodiments of the present application further provide a method for controlling an insufflator, which is applied to the insufflator control system provided in the first aspect. The method comprises the following steps:

[0080] S1, adjusting the states of the proportional valve state machine and the exhaust valve state machine to stabilize the abdominal cavity pressure information within a target range. The step of adjusting the states of the proportional valve state machine and the exhaust valve state machine includes:

[0081] S11, when the exhaust valve state machine is in the exhaust closed state, controlling the proportional valve state machine to cyclically switch among the waiting state for insufflation, the insufflation state, and the waiting state after insufflation to establish pneumoperitoneum;

[0082] S12. During the process of establishing pneumoperitoneum, abdominal cavity pressure information is obtained in real time. When the abdominal cavity pressure information is greater than a first preset pressure, the proportional valve state machine is controlled to switch and lock to the waiting state for insufflation, and the exhaust valve state machine is controlled to switch from the exhaust closed state to the exhaust open state to perform abdominal cavity pressure relief. The first preset pressure is greater than or equal to the upper limit of the target range.

[0083] S13. During the abdominal pressure relief process, when the abdominal pressure information is less than the second preset air pressure, the exhaust valve state machine is controlled to switch from the exhaust open state to the exhaust waiting state, and after the abdominal pressure stabilizes, the exhaust valve state machine is controlled to switch from the exhaust waiting state to the exhaust closed state and the proportional valve state machine is controlled to be unlocked, and the second preset air pressure is less than or equal to the upper limit value of the target range.

[0084] Specifically, the pneumoperitoneum machine control method of the embodiment of the present application is applied to the pneumoperitoneum machine control system provided in the first aspect, and the microcontroller in the pneumoperitoneum machine control system can operate based on the pneumoperitoneum machine control method of the embodiment of the present application to establish pneumoperitoneum and adaptively adjust the abdominal cavity pressure.

[0085] More specifically, the pneumoperitoneum control method accurately controls the abdominal cavity pressure through the coordinated work of the proportional valve state machine and the exhaust valve state machine. The proportional valve state machine is responsible for gas supply, and the exhaust valve state machine is responsible for exhaust. During the normal process of establishing pneumoperitoneum, the proportional valve state machine switches cyclically between three states to gradually establish pneumoperitoneum through multiple cycles of inflation. During this process, the system monitors the abdominal cavity pressure in real time. When the pressure exceeds the first preset air pressure, the gas supply is immediately stopped and exhaust is started. During the pressure relief process, the system continuously monitors the pressure changes. When the pressure drops below the second preset air pressure, the system stops exhausting and enters a stable waiting stage to ensure that normal operation is resumed only after the pressure is truly stable.

[0086] More specifically, in some embodiments, the target range is a range of abdominal pressure suitable for doctors to perform surgical operations, including an upper limit and a lower limit, which can be set according to usage requirements; the first preset air pressure can be set to 105% to 110% of the upper limit of the target range, and the second preset air pressure can be set to 95% to 100% of the upper limit of the target range. Such a setting can create a pressure buffer zone, effectively preventing the system from frequently switching between air supply and exhaust.

[0087] More specifically, in other embodiments, the target range is a target abdominal pressure suitable for doctors to perform surgical operations, which can be set according to usage requirements. The pneumoperitoneum control method of the embodiment of the present application is used to adjust the abdominal pressure to dynamically fluctuate near the target abdominal pressure to maintain a relatively stable state; the first preset air pressure can be set to 105% to 110% of the target abdominal pressure, and the second preset air pressure can be set to 95% to 100% of the target abdominal pressure. Such a setting can create a pressure buffer zone, so that the abdominal pressure can be kept dynamically fluctuating near the target abdominal pressure, effectively preventing the system from frequently switching between air supply and exhaust.

[0088] It should be noted that during the process of establishing pneumoperitoneum, if the abdominal cavity pressure information is lower than the lower limit of the target range for a long time, it indicates that pneumoperitoneum cannot be effectively established at present and an error report is required.

[0089] It should be noted that when the abdominal pressure information is greater than the first preset air pressure, it can mean that the abdominal pressure information collected in real time is greater than the first preset air pressure, or it can mean that the average value of the abdominal pressure information collected within a period of time (such as 3 seconds) is greater than the first preset air pressure. The explanation of the abdominal pressure information being less than the second preset air pressure is the same.

[0090] More specifically, compared with the simple switch control or PID control commonly used in traditional methods, the present application achieves more precise and intelligent pressure control by introducing a state machine and dual threshold control. Traditional methods often have a delayed response when dealing with sudden increases in intra-abdominal pressure, which may cause patient discomfort or safety risks. In contrast, the method of the present application can quickly respond to pressure changes and relieve pressure in a timely manner, greatly improving the safety of the system. In addition, the method of the present application effectively reduces the frequent switching of the system and improves the stability and efficiency of the system by creating a pressure buffer zone, which is difficult to achieve with traditional methods.

[0091] The insufflator control method of the embodiment of the present application realizes the intelligent and precise control of the insufflator by introducing the concept of a state machine. The proportional valve state machine switches cyclically between three states: waiting for air blowing, during air blowing, and waiting after air blowing. This design enables the system to flexibly adjust the air supply according to actual needs, avoiding the problems of excessive air supply or insufficient air supply that may occur in traditional control methods; secondly, a dual-threshold control strategy is introduced, which can adaptively adjust the exhaust and pressure relief of the overshooting abdominal pressure, effectively preventing the potential risks caused by excessive abdominal pressure, and when the pressure drops below the second preset air pressure, the system will not resume air supply immediately, but enter a stable waiting stage, which can further avoid frequent switching due to pressure fluctuations and improve the stability of the system.

[0092] In some preferred embodiments, the method further comprises the following steps:

[0093] S2. Draw curves showing the change of the output abdominal pressure information, the states of the proportional valve state machine, and the exhaust valve state machine with respect to time.

[0094] Specifically, if Figure 5 As shown, the change curve drawn in step S2 constitutes a timing diagram of the abdominal pressure information, the states of the proportional valve state machine and the exhaust valve state machine; wherein, in the figure, 0, 1, and 2 at the states of the proportional valve state machine represent the waiting state for insufflation, the insufflation state, and the waiting state after insufflation, respectively, and 0, 1, and 2 at the states of the exhaust valve state machine represent the exhaust closed state, the exhaust open state, and the waiting state after exhaust, respectively.

[0095] More specifically, the curves drawn in step S2 provide intuitive visualization information for medical staff. By plotting these curves, medical staff can clearly observe fluctuations in intra-abdominal pressure, the switching states of the proportional and exhaust valves, and their interrelationships. This intuitive display makes it easier for medical staff to identify potential abnormalities, such as sudden increases or decreases in pressure or abnormal valve switching. Furthermore, these curves provide valuable data support for subsequent analysis and optimization of system performance.

[0096] More specifically, the drawing and outputting steps of the present application can be implemented in a variety of ways. For example, a real-time drawing method can be used, that is, the latest data points are continuously updated and displayed during the operation of the pneumoperitoneum machine; or a periodic refresh method can be used, where the chart is updated at regular intervals (such as 1 second or 0.5 seconds).

[0097] More specifically, in order to improve the readability of the data, the present application can also add auxiliary lines and marks in the chart, such as adding a mark line for the target range so that medical staff can quickly determine whether the current pressure is within a safe range. At the same time, obvious marks can be added at the state switching points to highlight the time of occurrence of key events.

[0098] In some preferred embodiments, the process of controlling the proportional valve state machine to cyclically switch among the waiting for air blowing state, the air blowing state, and the waiting state after air blowing is performed based on a preset switching interval.

[0099] Specifically, the preset switching interval includes the waiting for blowing state duration interval, the blowing state duration interval and the waiting state after blowing state duration interval, which respectively represent the single duration of the waiting for blowing state, the blowing state and the waiting state after blowing.

[0100] Specifically, the above-mentioned control method based on the switching interval can make the state switching of the proportional valve state machine more precise and controllable. By setting the preset switching interval, the pneumoperitoneum machine control method of the embodiment of the present application can more accurately control the duration of each state, thereby achieving fine adjustment of the pneumoperitoneum establishment process. This refined control helps to better maintain the abdominal cavity pressure within the target range and improve the stability and safety of pneumoperitoneum establishment. In addition, this control method based on the preset switching interval also provides greater flexibility for the system; according to different surgical requirements or patient conditions, these preset switching intervals can be adjusted to achieve personalized customization of the pneumoperitoneum establishment process.

[0101] In some preferred embodiments, the proportional valve opening and the preset switching interval are generated based on the target range.

[0102] Specifically, the proportional valve opening determines the air delivery rate, while the preset switching interval influences the switching frequency of the state machine, which determines the average inflation duration per unit time. By generating these two parameters based on the target range, the system can adaptively adjust the control strategy according to different target pressure requirements.

[0103] More specifically, this application provides multiple implementations for generating proportional valve openings and preset switching intervals based on target ranges. One method uses a lookup table to pre-set proportional valve openings and switching intervals based on different target ranges. Another method employs dynamic calculation algorithms, such as linear interpolation or nonlinear functions, to generate parameters in real time based on the target range.

[0104] More specifically, when the target range is high, the system automatically generates a larger proportional valve opening and a shorter switching interval to quickly achieve and maintain a higher intra-abdominal pressure. Conversely, when the target range is low, the system generates a smaller proportional valve opening and a longer switching interval, effectively preventing excessively rapid pressure increases and reducing fluctuations. This adaptive mechanism significantly improves the accuracy and adaptability of pneumoperitoneum pressure control; the automatically generated proportional valve opening and preset switching interval reduce the complexity and potential errors of manual settings, greatly improving the system's ease of use and reliability.

[0105] In some preferred embodiments, in step S1, the following steps are further included between step S12 and step S13:

[0106] S14. After each abdominal cavity decompression process is performed, the duration of the insufflation state is reduced, or the duration of the waiting for insufflation state is increased.

[0107] Specifically, the pneumoperitoneum control method of the embodiment of the present application achieves adaptive optimization of inflation behavior by adding step S14. Specifically, reducing the duration interval of the insufflation state can reduce the amount of gas in a single insufflation, reducing the risk of a rapid increase in abdominal pressure; increasing the duration interval of the waiting insufflation state can extend the interval between two insufflations, giving the abdominal pressure more time to fall, which is equivalent to reducing the average inflation time per unit time. Both of these adjustment methods help to more precisely control the insufflation process after abdominal pressure relief, thereby better maintaining the stability of abdominal pressure and achieving adaptive adjustment of the insufflation strategy, thereby better maintaining the abdominal pressure within the target range.

[0108] In some preferred embodiments, decreasing the duration interval of the blowing state is decreasing based on a preset percentage value, and increasing the duration interval of the waiting blowing state is increasing based on a preset percentage value.

[0109] Specifically, this percentage-based dynamic adjustment method can adaptively adjust the control parameters according to actual conditions, thereby achieving more precise and stable abdominal pressure control and effectively reducing the number of unnecessary exhaust times.

[0110] More specifically, the duration of the insufflation state can be reduced linearly or nonlinearly. For example, a fixed percentage value, such as 5% or 10%, can be set. After each abdominal deflation, the current duration of the insufflation state is multiplied by (1-percentage value). Alternatively, a decreasing percentage value can be used, initially set at 10%, and then reduced by 1 percentage point each time until it reaches a minimum of 3%.

[0111] More specifically, a linear increase or a nonlinear increase may be used to increase the duration of the waiting-for-air-blowing state.

[0112] More specifically, this percentage-based dynamic adjustment method, combined with the aforementioned state machine control, forms an adaptive control system. When excessive intra-abdominal pressure triggers pressure relief, the system not only performs the pressure relief operation but also automatically adjusts subsequent control parameters. This adjustment takes into account the system's historical performance, making control more precise and personalized.

[0117] The pressure relief trigger module 3012 is used to obtain abdominal pressure information in real time during the process of establishing pneumoperitoneum, and when the abdominal pressure information is greater than a first preset pressure, control the proportional valve state machine to switch and lock to the waiting for insufflation state, and control the exhaust valve state machine to switch from the exhaust closed state to the exhaust open state to perform abdominal pressure relief. The first preset pressure is greater than or equal to the upper limit of the target range;
