[0047] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0049] In the related art, the display of anesthesia machine status information is usually performed by combining all relevant information into one display interface. For example, the gas source pressure information, the patient's breathing condition information, the anesthesia machine capacity information, etc. are displayed simultaneously in one display interface. Figure 1 As shown, different status information contains a large amount of data, resulting in unintuitive display. The specific parameters representing different status information can only be displayed in small text due to the limited size of the status screen. This makes it difficult for medical staff to obtain important information from the display interface and cannot accurately grasp the amount of information about the anesthesia process. This can lead to incomplete and incomplete monitoring of the patient's respiratory status, affecting anesthesia safety.

[0050] In response to the above technical problems, an embodiment of the present application provides an anesthesia machine display solution. In response to changes in the device status of the anesthesia machine, the currently displayed first display interface is switched to the second display interface corresponding to the current device status. When the current device status is the anesthesia mode state, in response to a touch operation on the second display interface, the visualization sub-interface to be displayed is determined from the multiple visualization sub-interfaces about different anesthesia status information included in the second display interface. The visualization sub-interface is then displayed. In this process, by automatically switching to the display interface corresponding to the device status according to the device status, and displaying the visualization sub-interface related to the anesthesia status information based on the interactive switching method triggered by the user in the anesthesia mode state, medical staff can pay more attention to the display screen they select, reducing the information carrying capacity of the status screen, making the status information more focused and flexible to display, thereby improving anesthesia safety.

[0051] Figure 1 A hardware architecture diagram of a possible application of an anesthesia machine display method provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the anesthesia machine can adopt a layered architecture to realize the monitoring of the entire anesthesia process through the architecture of state perception layer → data processing layer → visual interaction layer → anesthesia machine execution unit. Optionally, an event-driven architecture (EDA) is adopted to automatically switch the interface when the sensor data meets the state transition threshold. Example: When the O2 concentration is monitored to be >21% and the airway pressure fluctuation is <2cmH2O for 5 seconds, the standby → anesthesia mode switch is triggered. The state perception layer can be implemented using the anesthesia process state machine (Anesthesia Process State Machine, APSM), which is an intelligent decision-making model developed based on the finite state machine theory. As shown in Table 1 below, it can include three core states and transition conditions:

[0052] Table 1

[0053] state Trigger Conditions Show focus Self-test mode Power on the device Such as gas source pressure verification / sensor calibration progress Standby mode Self-test passed and no patient connected Such as gas cylinder remaining quantity / ambient temperature and humidity monitoring Anesthesia mode Patient airway tube connection completed Such as respiratory waveform / compliance parameters / dynamic lung animation

[0054] Based on the above hardware layer architecture, during the startup phase: after the system is powered on, hardware initialization and software loading are performed to detect the normal operation of each module (such as the data acquisition module, data processing module, display module, interaction module, etc. corresponding to each layer in the layered architecture), laying the foundation for subsequent processes.

[0055] Hardware initialization: Detect and initialize the hardware such as various sensors (such as the air source pressure sensor and flow sensor in the data acquisition module), circuit boards, display screens (also known as status screens) to ensure that they are in normal working condition.

[0056] Software loading: Load the system software and related configuration files stored in the memory into the internal memory, prepare for operation, and provide software support for subsequent processes.

[0057] Self-test and standby phase: Comprehensively test the functions of all components of the equipment to promptly detect potential faults and ensure equipment reliability; in standby mode, the equipment is ready to respond to anesthesia instructions from medical staff at any time and quickly enter working mode.

[0058] Comprehensive testing: Detailed testing of each key component of the equipment, including the sensitivity of the sensor, the stability of the circuit board, the display effect of the display, etc., to ensure the overall performance of the equipment is good.

[0059] Quick response: In standby mode, the system maintains low power consumption and monitors the medical staff's operating instructions in real time. Once an anesthesia instruction is received, the anesthesia process can be started quickly to reduce waiting time.

[0060] Anesthesia stage: Real-time collection and analysis of the patient's respiratory and other physiological data, combined with the equipment's operating status, to provide medical staff with comprehensive, real-time monitoring information to ensure the safety and effectiveness of the anesthesia process.

[0061] Real-time monitoring: During anesthesia, the system continuously collects patient respiratory parameters and equipment operation data through sensors, such as airway pressure, tidal volume, respiratory rate, etc., to ensure the real-time and accuracy of the data.

[0062] Comprehensive analysis: Comprehensively analyze the collected data to determine the patient's respiratory status and equipment working conditions, detect abnormal conditions in a timely manner and issue alarms, providing medical staff with a reliable basis for decision-making.

[0063] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0064] The above is a brief description of the scenario diagram of this application. Figure 1 Taking the anesthesia machine in the example as an example, the anesthesia machine display method provided by the embodiment of the present application is described in detail.

[0065] Please refer to Figure 2 , Figure 2 A flowchart of an anesthesia machine display method is provided for an embodiment of the present application, and the method includes steps S201-S203.

[0066] Step S201: In response to a change in the device state of the anesthesia machine, switching the currently displayed first display interface to a second display interface corresponding to the current device state.

[0067] Optionally, the device status of the anesthesia machine may include a self-test state, a standby state, an anesthesia state, etc. The anesthesia machine may automatically switch to the display interface under the corresponding device status, making it easier for medical staff to observe the display interface under the corresponding device status. Figure 3a-3c As shown in the figure, they are the display interface diagrams of self-test state, standby state and anesthesia state respectively, among which, Figure 3a As shown in the figure, in the self-test state, the self-test logo is displayed, and information such as gas source pressure verification / sensor calibration progress can be displayed; Figure 3b As shown, in standby mode, the gas source pressure information can be displayed, and dynamic data can be displayed in the form of a dashboard to quickly grasp the focus of medical staff for easy observation; Figure 3c As shown, in the anesthesia state, there is a lot of anesthesia state information that needs to be displayed and the information load is too large. And as the anesthesia process progresses, the focus of medical staff is different, and it supports interactive selection of display sub-interfaces for displaying different anesthesia state information, such as the lung animation visualization sub-interface, which displays current respiratory compliance and other data. In some embodiments, for different gas (gas used for anesthesia) configurations and gas alarms, in order to facilitate the observation of medical staff, the display interface in the standby state can display information about the gas configuration, compared with the above Figure 3b The figure shows a scenario where only central gas is configured (only oxygen and air pressure are shown as 72 psi), and both gases are supplied through the central gas supply system. Figure 4a-4d As shown, Figure 4a Three gas configurations + full gas cylinders are shown: oxygen (O2), nitrous oxide (N2O), and air (AIR) are all at 72 psi, with all three gases supplied by cylinders; Figure 4b Shown is the central gas without nitrous oxide + full gas cylinder: without nitrous oxide configuration, only oxygen and air pressure are shown at 72kPa×100, and oxygen and air are supplied by gas cylinders; Figure 4c Two gases, central gas + gas cylinder, are shown: oxygen and air pressure is shown to be 72kPa×100, and the two gas supply modes are a combination of central gas and gas cylinder; Figure 4d The alarm situation is shown. For example, if the oxygen reaches 72kPa×100 (for example, the alarm is displayed in red when the value 72 is displayed), an alarm prompt will be displayed in the interface, or other reasons such as gas supply stability, gas ratio, system failure, etc. may also trigger an alarm.

[0068] Optionally, a state machine can be used to monitor changes in the anesthesia machine's device status and switch display interfaces. For example, the possible states of the anesthesia machine, such as power-on self-test, standby, and anesthesia, can be defined, as well as events that may cause state changes, such as power-on completion and the start of anesthesia. A state transition diagram can be designed to clarify the transition conditions between each state, and the state machine logic can be implemented using a programming language to enable receiving events and transitioning based on the current state. In some embodiments, by associating the anesthesia machine's sensors and control signals with state machine events, it is possible to trigger interface updates and switch to the corresponding display interface when the state changes.

[0069] Among them, the first display interface and the second display interface can be the same display interface (such as the interface layout, the display content is the same), or they can be different display interfaces. For example, the first display interface can be the device self-test parameter interface corresponding to the self-test state, the basic monitoring interface corresponding to the standby state, and the anesthesia display interface corresponding to the anesthesia mode state; or, the second display interface can be the device self-test parameter interface corresponding to the self-test state, the basic monitoring interface corresponding to the standby state, and the anesthesia display interface corresponding to the anesthesia mode state. The anesthesia display interface includes multiple visual sub-interfaces about different anesthesia status information. It should be understood that the first display interface corresponds to the display interface of the device state before the current device state, and the second display interface corresponds to the display interface of the current device state.

[0070] In response, it is used to indicate the conditions or states on which the executed operations depend. When the dependent conditions or states are met, one or more operations executed can be in real time or with a set delay. Unless otherwise specified, there is no restriction on the order of execution of the multiple operations executed.

[0071] Step S202: When the current device state is the anesthesia mode state, in response to a touch operation on the second display interface, determine a visualization sub-interface to be displayed from a plurality of visualization sub-interfaces related to different anesthesia state information included in the second display interface.

[0072] After research, it was found that the anesthesia mode status involves a large amount of anesthesia status information (hereinafter referred to as status information), such as gas source pressure information, lung animation information, etc. If this information is simply listed and displayed in the display interface, it will be difficult for medical staff to focus on the corresponding display content. In this embodiment, the user is supported to flexibly interact with the interface and select the content to be displayed. Optionally, in the initial state, a default screen pre-set by the user can be displayed (such as displaying basic information of all status information, or preferentially displaying detailed information of a certain status information).

[0073] For example, touch operations can include screen swiping, gestures, and other interactive operations. These touch operations allow medical staff to quickly switch between different interfaces and access required information, improving operational convenience and work efficiency. For example, the anesthesia machine can support multi-touch operation, allowing medical staff to switch interfaces, view and set parameters, and perform other functions through simple gestures such as swiping and pinching. For example, during the anesthesia phase, medical staff can swipe left and right on the status screen to switch between different interfaces, such as swiping the lung animation interface to switch to the pressure gauge interface. Alternatively, pinching and pinching can be used: The lung animation supports pinch-to-zoom interaction, allowing medical staff to zoom in on the lung animation to view respiratory status. In actual operation, medical staff can: 1) Under normal circumstances, zooming in on the lung animation can demonstrate the dynamic process of oxygen diffusion from the bronchi to the alveoli into the bloodstream. 2) When compliance is excessive, zooming in on the lung animation can graphically demonstrate the loss of alveolar elastic recoil and the collapse of small bronchi.

[0074] 3) When compliance is too low, the enlarged lung animation will show airway obstruction and a graphic display of gas exchange impairment.

[0075] 4) When the resistance is too great, the enlarged lung animation shows that the airflow in the airway is significantly obstructed, with some gas trapped.

[0076] By way of further example, in combination Figure 5a-5d Different visualization sub-interfaces are shown, Figure 5a The gas source pressure interface is shown, and the real-time value of the gas source pressure is displayed on the instrument panel; as mentioned above, Figure 3c The lung animation interface is shown, focusing on the patient's breathing situation, and can simultaneously display various information such as resistance, compliance, elasticity, respiratory time constant, spontaneous breathing mark, asphyxia status, etc. Figure 5b The respiratory pressure interface is shown, which displays respiratory pressure (i.e., airway pressure) monitoring information and can also be displayed in the form of a dashboard; Figure 5c It shows a respiratory capacity interface, which displays respiratory capacity (ie, airway capacity) monitoring information and can also be displayed in the form of a dashboard.

[0077] Step S203: Display the visualization sub-interface.

[0078] As mentioned above, when displaying a visualization sub-interface selected by the user, such as the lung animation interface, medical staff can also use touch operations to enlarge or reduce the display of the lung animation interface to optimize the display effect of the visualization sub-interface.

[0079] For example, the visualization sub-interface may be displayed on the anesthesia machine status screen, or may be displayed on the main interface, which is not particularly limited in this embodiment.

[0080] Through the above technical solution, the interface automatically switches based on the device status, and the interface of human-computer interaction switches flexibly. The anesthesia machine can display the main parameters and visual content corresponding to different processes according to different stages, reducing the information load of the status screen, allowing medical staff to concentrate on the current key tasks, that is, focusing on the current tasks, avoiding the tedious process of screening the required data from a large amount of information, and improving the efficiency and safety of anesthesia work.

[0081] In some embodiments, in response to a touch operation on a visualization sub-interface, the display may be switched to another visualization sub-interface other than the currently displayed visualization sub-interface, wherein the switching of the visualization sub-interfaces is achieved through a predefined mapping relationship between the touch gesture and the visualization sub-interface.

[0082] Those skilled in the art can adaptively configure touch gestures based on actual applications or prior data. For example, a user can use a swipe operation to switch between the various visualization sub-interfaces described above. For example, if the currently displayed visualization sub-interface is a lung animation interface, a left swipe can switch to the air source pressure interface, or a right swipe can switch to the respiratory capacity interface.

[0083] In this way, by switching the display of the visualization sub-interfaces, the medical staff's flexible observation of different visualization sub-interfaces is improved.

[0084] Figure 6 This is a flow chart of another anesthesia machine display method provided by an embodiment of the present application, such as Figure 6 As shown, based on the above embodiment, this embodiment realizes interactive display of the process of anesthesia surgery and the main interface of the anesthesia machine through a visual interface corresponding to the real-time status of the anesthesia machine and the real-time generated anesthesia status of the anesthesia subject, further improving the real-time and interactivity of the anesthesia machine display. Specifically, in addition to the above steps S201-S203, the method provided in this embodiment can also include steps S601 and S602.

[0085] Step S601: collecting the operating information of the anesthesia machine and / or the breathing information of the anesthetized subject in real time.

[0086] For example, an anesthesia machine may include a variety of sensors, such as gas source pressure sensors, flow sensors, and capacity sensors. These sensors are installed in key locations on the anesthesia machine (in some embodiments, they may also be electrically connected to multiple sensors to communicate and obtain relevant data). They collect physical signals in real time and convert them into electrical signals for subsequent processing to obtain operating information of the anesthesia machine or respiratory information of the anesthetized subject. For example, an airflow sensor can use advanced thermal measurement principles to accurately calculate respiratory airflow velocity and flow by detecting heat changes caused by gas flow; an air pressure sensor can convert pressure changes into resistance changes based on the piezoresistive effect to obtain accurate airway pressure readings. To improve data acquisition accuracy, these sensors can have micron-level accuracy and millisecond-level response speeds, so that the captured respiratory signals are both accurate and timely.

[0087] Step S602: Acquire anesthesia status information according to the operation information and / or respiratory information, and generate a corresponding visualization sub-interface according to the anesthesia status information.

[0088] For example, after collecting relevant operating information and respiratory information, a high-performance microcontroller or processor can be used to perform pre-processing operations such as filtering, amplification, and analog-to-digital conversion on the collected signals, and the data can be analyzed and processed to determine the device status and status information related to anesthesia. For example, the signal can be filtered first, and the filter parameters can be dynamically adjusted using an adaptive filtering algorithm to effectively remove signal impurities caused by environmental noise, electromagnetic interference of the device itself, etc., to ensure the purity of the signal. Feature extraction can then be performed, and mathematical tools such as wavelet transform can be used to perform multi-scale analysis on the filtered signal to accurately identify key feature points in the respiratory process, such as the inspiratory peak and the expiratory trough, so as to calculate respiratory parameters such as respiratory rate and tidal volume. In addition, by establishing a respiratory mechanics model, combined with real-time monitored airflow and air pressure data, the finite element analysis method can be used to simulate the mechanical behavior of lung tissue, and then pulmonary function parameters such as respiratory compliance and airway resistance can be inferred.

[0089] In one embodiment, the anesthesia status information includes lung function parameter information, and the visualization sub-interface includes a lung animation interface. In the above step S602, the anesthesia status information is obtained based on the operation information and / or respiratory information, and the corresponding visualization sub-interface is generated based on the anesthesia status information, which can be:

[0090] According to the respiratory information, the lung function parameter information is obtained, and the lung function parameter information includes dynamic compliance, airway resistance, spontaneous breathing information and respiratory rate;

[0091] Determine, in real time, a dynamic respiratory state index for a lung animation interface based on the lung function parameter information, including at least one of the following: a dynamic lung characteristic index, spontaneous breathing intensity, an asphyxia risk index, and a respiratory change rate;

[0092] A lung animation interface is generated based on the dynamic respiratory status index, and the lung animation interface includes at least one of the following: a lung graphic for displaying a morphological or color presentation based on the dynamic lung characteristic index, identification information for displaying whether it is spontaneous breathing based on the spontaneous breathing intensity, identification information for displaying whether asphyxiation is occurring based on the asphyxiation risk index, and a fluctuation curve for displaying the respiratory change rate.

[0093] For example, during the collection of respiratory information, the embedded system can control the synchronous sampling of airflow, air pressure, and temperature sensors (sampling rate ≥ 200Hz) to ensure time stamp alignment. The original signal is subjected to sliding average filtering (window width 5ms) and low-pass filtering (cutoff frequency 50Hz) to eliminate high-frequency noise and mechanical vibration interference. In one implementation, respiratory information can be used to obtain lung function parameter information in the following manner:

[0094] First, the tidal volume (V) of a single respiratory cycle is calculated using the flow-volume conversion method. t For example, according to the calibration curve of the thermal flow sensor, the airflow velocity signal is converted into real-time gas flow (Q) in L / min. The flow signal is time-integrated to calculate the tidal volume (V) of a single respiratory cycle. t )

And respiratory phase segmentation and feature extraction, respiratory cycle segmentation, based on the flow signal zero crossing point detection, divided into the inspiration phase (Q>0) and the expiration phase (Q<0), and the pressure signal is used to verify the accuracy of the segmentation. And dynamically mark the key time points: the start of inspiration (t start ), peak inspiratory flow rate (t peak ), end of exhalation (t end ).

[0096] Then, the respiratory mechanics parameters are calculated, that is, the lung function parameters are calculated. For example, (respiratory) dynamic compliance (C rs ) can be calculated in volume-controlled ventilation mode without spontaneous breathing using the end-inspiratory pause method, which can be calculated using the following formula:

[0097]

[0098] Where, P plat PEEP stands for positive end-expiratory pressure, which is the positive pressure applied at the end of expiration to keep the alveoli open and prevent alveolar collapse.

[0099] In spontaneous breathing or pressure support mode, a dynamic compliance algorithm is used:

[0100]

[0101] Where ΔV represents the volume change of the lungs during one respiratory cycle, which corresponds to the tidal volume V t , that is, the volume of gas inhaled or exhaled; ΔP represents the change in airway pressure during the inspiratory phase, including the pressure difference between the positive end-expiratory pressure and the peak pressure at the end of inspiration.

[0102] The airway resistance (Raw) can be calculated by fitting the pressure-flow curve based on the Euler equation (equation of motion), as shown in the following formula:

[0103]

[0104] Where, P airway (t) represents the airway pressure at time t, Q(t) represents the airway rate at time t, V(t) represents the lung volume at time t, and P0 represents the baseline pressure, such as the externally applied pressure.

[0105] The respiratory rate can be obtained by extracting the real-time respiratory rate (RR), such as using the flow sensor signal to identify a single respiratory cycle (inhalation + exhalation) through zero-crossing detection, and calculating the interval time T (seconds) between two adjacent respiratory cycles. The respiratory rate RR = 60 / T (times / minute).

[0106] Spontaneous breathing information refers to whether the patient has the ability to breathe independently. The patient's spontaneous breathing ability can be directly identified through the slight fluctuation of the flow signal (input FFT analysis of the 0.1-0.5Hz frequency band energy).

[0107] By combining one or more of the lung function parameter information obtained above, the dynamic respiratory state index for the lung animation interface can be determined in real time, including at least one of the following: dynamic lung characteristic index, spontaneous breathing intensity, asphyxia risk index and respiratory change rate. For example, the dynamic lung characteristic index can be multiple parameters mentioned above, such as dynamic compliance (Compl, unit: ml / cmH2O), airway resistance (Raw, unit: cmH2O / (L / s); spontaneous breathing intensity is whether the patient has the ability to breathe independently; asphyxia risk index is determined based on the flow signal and / or pressure fluctuation that changes over time. For example, if there is no valid flow signal for 5 consecutive seconds and the pressure fluctuation is less than 2cmH2O, an alarm can be triggered; for the respiratory change rate, a sliding window can be used for dynamic tracking: for example, a time window is set (such as 30 seconds), and the respiratory rate RR value of all respiratory cycles in the window is recorded. The standard value (SD) and coefficient of variation (CV) of RR in the window are calculated.

[0108]

[0109] Where, CVRR Respiratory rate coefficient of variation, SD (RR) represents the standard value of respiratory rate, and Mean (RR) represents the mean value of respiratory rate.

[0110] Based on the calculated CV RR , the respiratory (frequency) change rate (ΔRR) can be defined as the CV of two adjacent windows RR The difference reflects respiratory stability. After back-end data processing, it is returned to the front-end for plotting as a fluctuation curve and percentage value. When the respiratory rate increases or decreases, the curve will fluctuate. The amplitude of the fluctuation reflects the speed of the frequency change. When the patient's breathing is stable, the curve flattens to a near straight line.

[0111] Exemplarily, the following interface information can be displayed in the lung animation interface: dynamic lung picture (graphic symbol), with the dynamic lung needing to display the contraction / relaxation process as it inhales and exhales; dynamic compliance (numerical display); airway resistance (numerical display); spontaneous breathing intensity (Fspont, unit: bpm) (numerical display); indicator C20 / C for evaluating lung compliance (numerical display); spontaneous breathing symbol (graphic symbol); asphyxia state (graphic symbol); respiratory change rate (numerical display, percentage value), etc.

[0112] For example, during the generation of the lung animation interface, corresponding animation effects can be designed based on different respiratory states, such as the speed and amplitude of lung expansion and contraction, the patency of the airway, etc., to vividly reflect the patient's respiratory condition. The display form can be: the lung contour reflects compliance, with high compliance resulting in a soft and collapsed lung contour, and low compliance resulting in a hard and sharp lung contour; normal compliance results in a full lung contour; the color of the trachea reflects the resistance, with purple in normal conditions and red when resistance is high; the overall color reflects suffocation or other abnormal conditions requiring an alarm; the semi-curved diaphragm below the lungs represents the respiratory diaphragm, which is displayed when the patient is monitored to have spontaneous breathing; the movement frequency: the lungs expand during exhalation and shrink during inhalation. The judgment criteria are as follows: 1. Based on dynamic compliance, there are four dynamic lung states: (a) No compliance detected (with a status indicator); (b) Normal compliance: when the compliance value is within the range of (compliance lower limit, compliance upper limit); (c) High compliance (soft lung) (with a status indicator): when the compliance value is within the range of (high limit, 300); (d) Low compliance (hard lung) (with a status indicator): when the compliance value is within the range of (0, low limit); 2. Based on airway resistance, there are three dynamic lung states: (a) No resistance detected (with a status indicator); (b) Normal resistance: when the resistance value is within the range of (0, high limit); (c) High resistance (with a status indicator): when the resistance value is within the range of (high limit, 600). The compliance upper / low limit and resistance upper limit can be configured by the medical staff, for example, in the settings menu on the main screen. In the case of apnea (with a status indicator), the dynamic lung function turns red. Note that the apnea status of the dynamic lung function is linked to the device's apnea alarm. When any apnea alarm (apnea, apnea > 2 minutes, CO2 apnea) is triggered, the dynamic lung function indicates apnea. The spontaneous breathing indicator is displayed in the form of the diaphragm, and its appearance can be synchronized with the spontaneous breathing indicator on the main interface waveform.

[0113] Specifically, it is used to display lung graphics in a morphological or color-coded manner according to the dynamic lung characteristic index. Figure 3c ,as well as Figure 7a-7c As shown ( Figure 3c It shows that the compliance and resistance are normal; Figure 7a It shows that no compliance, resistance was detected; Figure 7b Shows excessive compliance - soft lung, normal resistance; Figure 7c It shows that the compliance is too small - hard lung, resistance is too large. It should be understood that the color is not distinguished in the figure. In actual application, the corresponding color can be displayed in combination with the above example) to display the identification information of whether it is spontaneous breathing according to the spontaneous breathing intensity, such as Figure 8 As shown, the identification information for displaying whether suffocation is determined according to the suffocation risk index is as shown in Figure 9a and 9bAs shown in the figure, and the fluctuation curve used to show the respiratory rate of change is as follows Figure 10 shown.

[0114] By dynamically acquiring and displaying lung function parameters such as dynamic compliance and airway resistance, and generating a lung animation interface based on dynamic respiratory status indicators, the system provides immediate feedback on the patient's respiratory status. This allows the lung animation interface to vividly reflect the patient's respiratory status, such as excessive / inadequate compliance, excessive resistance, or suffocation, through vivid animation effects, helping medical staff more intuitively observe and judge the patient's condition. This real-time monitoring capability enables medical staff to more quickly identify potential problems such as dyspnea or obstruction, thereby improving patient safety.

[0115] In another embodiment, the anesthesia status information includes gas source pressure information, and the visualization sub-interface includes a gas source pressure interface. In the above step S602, the anesthesia status information is obtained based on the operation information and / or respiratory information, and the corresponding visualization sub-interface is generated based on the anesthesia status information, which can be:

[0116] According to the operation information, obtain the gas source pressure information of each gas supply device of the anesthesia machine;

[0117] According to the gas source pressure information of each gas supply device, the dynamic gas source pressure change information of each gas supply device is determined in real time;

[0118] An air source pressure interface is generated according to the dynamic air source pressure change information of each air supply device. The air source pressure interface includes a digital instrument panel for displaying the dynamic air source pressure change information.

[0119] Optionally, medical staff can select multiple gas supply devices for gas supply.

[0120] This embodiment can collect the gas source pressure information of each gas supply device in real time through the operating information of the anesthesia machine, use the gas source pressure information to obtain the dynamic pressure change information of each gas supply device, and display the real-time value and change trend of the gas source pressure in the gas source pressure interface.

[0121] In some embodiments, the anesthesia machine can automatically adjust the display content and layout of the gas source pressure interface according to different configurations and connection statuses, so that the gas source pressure information is displayed completely and accurately without the need for manual adjustment by medical staff, further improving the convenience of operation. For example, the anesthesia machine is connected to different types of gas sources, such as oxygen, air, and nitrous oxide (N2O) cylinders. Each gas source may have a different pressure range and safety threshold. When the anesthesia machine detects that an oxygen cylinder is connected, the anesthesia machine can automatically adjust the interface to display the oxygen pressure reading, remaining gas volume, and safety threshold warning. Can be combined with Figure 4a-4d Understand.

[0122] Through the above method, the gas source pressure interface adopts a digital instrument panel (the gas source pressure interface displays real-time values ​​and change trends in a combination of instrument panel and numbers), which is more intuitive and enables medical staff to quickly and accurately obtain key information.

[0123] In another embodiment, the anesthesia state information includes a respiratory pressure parameter and / or a respiratory volume parameter, and the visualization sub-interface includes a respiratory pressure interface and / or a respiratory volume interface. In the above steps, the anesthesia state information is obtained based on the operation information and / or respiratory information, and the corresponding visualization sub-interface is generated based on the anesthesia state information, which can be:

[0124] obtaining respiratory pressure parameters and / or respiratory volume parameters of the anesthetized subject based on the respiratory information;

[0125] Determine dynamic pressure parameter change information of the anesthetized subject in real time based on the respiratory pressure parameter, and generate a respiratory pressure interface based on the dynamic pressure parameter change information; and / or,

[0126] According to the respiratory capacity parameters, the dynamic capacity parameter change information of the anesthetized subject is determined in real time, and the respiratory capacity interface is generated according to the dynamic capacity parameter change information;

[0127] The respiratory pressure interface includes a digital instrument panel for displaying dynamic pressure parameter change information; the respiratory capacity interface includes a digital instrument panel for displaying dynamic capacity parameter change information.

[0128] Similar to the gas source pressure interface generation process, this embodiment displays the pressure and capacity parameters in the form of an intuitive dashboard through dynamic pressure parameter change information and dynamic capacity parameter change information. Medical staff can clearly see the parameter change trend and current value, which is convenient for real-time monitoring and adjustment.

[0129] Optionally, the instrument panel can be designed with clear scales and pointers to intuitively display the real-time values ​​and ranges of pressure and volume parameters, making it easier for medical staff to quickly obtain information. For example, the respiratory pressure interface is as follows: Figure 5b As shown, the respiratory capacity interface is as follows Figure 5c In some embodiments, a parameter change trend curve can also be added to the dashboard interface. Medical staff can understand the dynamic changes of the parameters by observing the trend of the curve, providing a basis for adjusting the anesthesia plan.

[0130] In some embodiments, for the various visual sub-interfaces described above, status prompt information, such as text descriptions, color changes, etc., can also be added to the animation interface to help medical staff more accurately judge the patient's respiratory status and improve diagnostic efficiency.

[0131] In some embodiments, in response to at least one of the dynamic respiratory state indicator, dynamic gas source pressure change information, dynamic pressure parameter change information, and dynamic capacity parameter change information reaching a preset alarm condition, a visualization sub-interface corresponding to the alarm condition can be displayed.

[0132] Among them, those skilled in the art can set relevant alarm conditions based on actual applications or experience values. For example, the currently displayed visualization sub-interface is a lung animation interface. If the anesthesia machine detects that the gas source pressure reaches the corresponding alarm condition (such as gas source failure or blockage, etc., oxygen reaches 72kPa×100. It should be understood that this value is only an example).

[0133] By dynamically switching the visual sub-interface under alarm conditions, medical staff can quickly identify risk issues under the current anesthesia state and improve anesthesia safety.

[0134] In a further example of this embodiment, if the visualization sub-interface to be displayed is a lung animation interface, displaying the alarm information in the corresponding visualization sub-interface can be achieved in the following manner:

[0135] Method 1: Switch the display form or color of part or all of the lung graphic in the lung animation interface to a preset alarm form or color.

[0136] In this embodiment, the display form may include the lung shape corresponding to the expansion and contraction of the lungs, and may be displayed in a specific display form when abnormal (e.g., the normal form is a full form that expands outward, and the alarm form may be a soft form that contracts inward). Partial areas of the lung image, for example, may be displayed only for the lung outline color, or only for the trachea color in the lungs, or for both the lung outline color and the trachea color. For example, the trachea color may reflect the size of the resistance, with purple being the normal state and red being the high resistance; or, the overall color may reflect suffocation or other abnormalities requiring an alarm state.

[0137] Various status information is intuitively fed back to medical staff through color changes and animation effects. For example, under normal conditions, parameters are displayed in white; when an abnormality occurs, the relevant parameter display turns red, accompanied by flashing or animation prompts, to ensure that medical staff can detect and handle it in time. For example, an intuitive color coding method can be used to correspond different status information to specific colors. Medical staff can quickly identify the status of equipment and patients by color, thereby improving response speed. In abnormal situations, animation effects (such as parameter flashing, animation jumping, etc.) can be used to further emphasize abnormal information, thereby prompting medical staff to handle it in time.

[0138] Method 2: Add alarm identification information to the lung animation interface.

[0139] For example, the alarm identification information can be displayed in text form in the lung animation interface.

[0140] Method 3: Combine the lung animation color display, shape display and alarm mark display in the above methods 1 and 2. The relevant instructions will not be repeated here.

[0141] For example, in combination Figures 7a-7c As shown, Figure 7a If compliance and resistance are not detected, the color of the lung graphic can be compared to the color of the lung graphic when compliance and resistance are detected (such as Figure 3c shown) is lighter in color; Figure 7b When the compliance is too high (those skilled in the art can determine the critical value corresponding to the compliance being too high based on actual application or experience), the shape of the lung graph (compared to Figure 3c The lungs have a full outline) and are in a soft couch shape; Figure 7c The compliance is too small (those skilled in the art can determine the critical value corresponding to the small compliance based on actual application or experience), the resistance is too large (those skilled in the art can determine the critical value corresponding to the large resistance based on actual application or experience), and the lung figure (compared to the smooth curve of the lung outline in 3c) is hard. The color of the trachea in the lung figure can be processed. For example, the normal lung figure is blue, but it is displayed in red due to the large resistance. Furthermore, it can be combined with Figure 9a and Figure 9b As shown, Figure 9a and Figure 9b In addition to the text alarm logo, the asphyxiation status can also be displayed with the color and shape of the lung graphics. For example, Figure 9a A red lung figure with a full outline can be presented (i.e., the lung outline and trachea color are both displayed in red, and in this embodiment, red can be an alarm color). Figure 9b The image of the lungs may appear soft, the trachea may appear red, and so on.

[0142] In some embodiments, in addition to the lung animation interface, other visualization sub-interfaces, such as the gas source pressure interface, the respiratory pressure and volume interface, etc., can also be fed back to medical staff through color, allowing users to clearly understand various abnormal conditions during the treatment process.

[0143] In a further example of this embodiment, to facilitate observation by medical personnel, the anesthesia machine can also zoom in or out on a designated area of ​​the visualization sub-interface in response to a zoom operation on the designated area. For example, medical personnel can interact with the visualization sub-interface through zooming operations. For example, a medical personnel can zoom in on a lung animation to view lung breathing status using a two-finger zoom gesture, or zoom out to view other parameter information using a finger pinch gesture.

[0144] In some embodiments, to further enhance the flexibility of the anesthesia machine display mode, the display range of each visualization sub-interface can be configured through the interactive function of the display interface. Specifically, the method may further include the following steps: in response to a touch operation on the third display interface, obtaining configuration information for configuring the display range of each visualization sub-interface corresponding to the second display interface. Displaying the corresponding visualization sub-interface according to the configuration information;

[0145] The third display interface is used to display basic parameter information of the anesthesia machine and configuration function items for configuring the second display interface. The third display interface and the second display interface are displayed in different display components of the anesthesia machine.

[0146] Exemplarily, the first display interface and the second display interface can be (switchably) displayed in the first display component, and the third display interface can be displayed in the second display component. The first display component can be a status screen, and the second display component can be the main screen of the anesthesia machine for displaying the main interface. The main screen can be used to display anesthesia scheme settings and various control options and adjustment parameters. In this embodiment, the configuration items of the display range of each visual sub-interface can be displayed on the main screen, such as designing a shortcut menu. Medical staff can quickly access the common functions and setting options of the status screen by clicking the menu button. Medical staff can configure the display range of the visual sub-interface on the main screen, such as customizing the information displayed on the status screen at different stages to improve operational efficiency.

[0147] For example, interactive modes can be configured, such as switching, zooming in and out, with important parameters highlighted and secondary parameters arranged in an orderly manner. Medical staff can use personalized settings to display visual graphics on the main anesthesia interface or status screen, allowing them to efficiently obtain key information under various conditions, such as at different distances and on different screens.

[0148] like Figure 11 As shown, medical staff can use the status display configuration item to configure which visual sub-screens are displayed on the status screen, as well as the parameters displayed in each visual sub-screen. Specifically, medical staff can interact with the anesthesia machine by touching and swiping the main screen, accessing different screens and functions on the status screen. This allows medical staff to customize the configuration and focus on the desired display content.

[0149] In summary, the intelligent interface display solution provided by this embodiment can effectively optimize medical staff's monitoring and management of patients' anesthesia status. Specifically, the gas source pressure interface automatically adjusts according to preset configurations, displaying the corresponding instrument panel and digital information about the gas cylinder, allowing medical staff to quickly obtain accurate data on the gas source status. The breathing lung animation interface dynamically displays the patient's respiratory status, including conditions such as excessive or insufficient compliance, excessive airway resistance, and asphyxia. This intuitive animation helps medical staff quickly identify and assess the patient's respiratory status. Furthermore, the pressure and volume instrument panels clearly display relevant parameters. Furthermore, medical staff can switch between different interfaces by swiping the screen and zooming with two fingers, making it convenient for medical staff to quickly access and view the required information. The main interface menu provides access to the status screen configuration and display content, allowing users to customize the display content as needed to meet different clinical needs. Furthermore, by monitoring device status and respiratory information in real time, abnormal conditions are fed back to medical staff through color changes and animation effects, allowing them to more clearly understand various abnormalities during treatment.

[0150] Based on the above technical solutions, the performance of anesthesia machines has been significantly improved in terms of information display, ease of operation, safety, work efficiency and adaptability to industry standards, providing medical staff with a higher-quality and more reliable anesthesia monitoring solution with important application value and promotion prospects.
