[0075] The processor 120 of the monitoring device 100 can be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor. The processor 120 is the control center of the monitoring device 100, connecting all parts of the monitoring device 100 via various interfaces and lines.

[0076] The display 110 is used to provide a visual display output to the user. Specifically, the display 110 can be used to provide a visual display interface to the user, including but not limited to a monitoring interface, a monitoring parameter setting interface, an alarm parameter interface, etc. The monitoring interface displayed on the display 110 is used to display the monitoring data monitored within a preset time period. For example, the display 110 can be implemented as a touch display, or a display 110 with an input panel, that is, the display 110 can be used as an input / output device.

[0077] The monitoring device 100 also includes a memory. The memory stores program code, and the processor 120 uses this program code to execute the steps in the following display method. The memory can be used to store patient monitoring data. The memory can primarily include a program storage area and a data storage area. The program storage area can store the operating system, applications required for multiple functions (such as sound playback, image playback, etc.), etc.; the data storage area can store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory can include high-speed random access memory, and may also include non-volatile memory, such as hard disks, RAM, plug-in hard disks, smart media cards (SMC), secure digital (SD) cards, flash cards, multiple disk storage devices, flash memory devices, or other volatile solid-state storage devices.

[0078] In some embodiments, the monitoring device 100 further includes sensors. The sensors, processor 120, and display 110 can be connected via wired or wireless communication protocols to enable data exchange between them. Wireless communication technologies include, but are not limited to, various generations of mobile communication technologies (2G, 3G, 4G, and 5G), wireless networks, Bluetooth, ZigBee, UWB, NFC, etc.

[0079] Specifically, the sensor is used to collect patient monitoring data. This monitoring data may include, but is not limited to, one or more vital signs parameters selected from electrocardiogram (ECG), respiration, pulse oximetry, heart rate, blood oxygen saturation, non-invasive blood pressure, and invasive blood pressure. In some embodiments, the sensor may be independently located outside the monitoring device 100, but detachably connected to it.

[0080] The processor 120 is also used to process monitoring data signals from sensors. Sensors include, but are not limited to, monitoring parameters such as electrocardiogram (ECG), respiration, blood oxygen saturation, blood pressure, cerebral blood flow, cerebral blood oxygen saturation, electroencephalogram (EEG), and cerebrovascular regulation. The monitoring device 100 is provided with several connection interfaces. These interfaces include, but are not limited to, ECG / respiration interfaces, blood oxygen saturation interfaces, invasive blood pressure interfaces, non-invasive blood pressure interfaces, cerebral blood flow interfaces, cerebral blood oxygen saturation interfaces, EEG interfaces, and cerebrovascular regulation interfaces. Monitoring parameter monitoring accessories are electrically connected to the monitoring device 100 through these connection interfaces. In some other embodiments, the sensors may also be integrated into the monitoring device 100.

[0081] In some other embodiments, the monitoring device 100 may not include sensors, and the monitoring device 100 may receive monitoring data collected by external monitoring accessories through a communication module.

[0082] The processor 120 can also be used to control the collaboration of various functional devices within the monitoring device 100. Specifically, the processor 120 processes vital sign parameters such as electrocardiogram, respiration, blood oxygen, blood pressure, cerebral blood flow, cerebral blood oxygen, electroencephalogram, and cerebrovascular regulation collected by sensors to obtain monitoring data, and controls the display 110 to display the monitoring data. The monitoring data includes, but is not limited to, at least one of parameter values ​​and parameter waveforms.

[0083] In some embodiments, the monitoring device 100 further includes an alarm module connected to the processor 120. The alarm module outputs alarm prompts to enable medical personnel to take appropriate rescue measures and to monitor the patient's condition and the device's operating status in real time, thereby preventing negligence by medical personnel or the patient and improving monitoring safety. The alarm module includes, but is not limited to, alarm lights and alarm speakers. For example, the alarm module includes a light-emitting diode and / or a buzzer to generate audible and visual alarm signals. When one or more monitored parameters exceed a preset threshold, such as heart rate below a preset threshold or blood pressure above a preset threshold, the alarm module is triggered, thereby alerting medical personnel. Specific alarm information can be displayed on a monitor, played through an audio alarm speaker, or printed out using a printing device.

[0084] To enable user interface and data exchange, in addition to the display 110, the monitoring device 100 may also include an input / output device connected to the processor 120.

Specifically, in some embodiments, the input / output device enables the monitoring device 100 to interface with a computer, and the user can input configuration parameters through the computer and the input / output device. In other embodiments, the input / output device enables the monitoring device 100 to connect to the network interface of the HLAN and can receive additional timestamped clinical information, such as blood gas data and laboratory results, which the user can use as additional input configuration parameters via the HLAN and the input / output device. In some embodiments, as described above, the display 110 may also serve as an input / output device, such as a touch screen.

[0085] The monitoring device 100 may also include a communication module connected to the processor 120.

The communication module includes, but is not limited to, Wi-Fi, Bluetooth, NFC, ZigBee, UWB, or mobile communication modules such as 2G, 3G, 4G, and 5G. Therefore, patient monitoring parameters and alarm information can be wirelessly transmitted through the communication module of the monitoring device 100 to a third-party device in the hospital for centralized monitoring. In other embodiments, the monitoring device 100 can also establish a connection with a third-party device via a cable. The third-party device includes, but is not limited to, a central monitoring service station device or a bedside monitor. The third-party device can also be a cloud service system or a mobile terminal such as a mobile phone, tablet computer, or personal computer.

[0086] The number of monitoring devices 100 may include one or more. A third-party device establishes data communication with at least one monitoring device 100. The third-party device includes a processor, a display, a memory, and an alarm module. The processor is the control center of the third-party device, connecting various parts of the entire third-party device through various interfaces and lines. In some embodiments, the functions of the processor, display, memory, and alarm module of the third-party device may include the same as those of the processor 120, display 110, memory, and alarm module of the monitoring device 100. For example, the processor of the third-party device may also be used to process monitoring data collected by sensors and control the display to show the monitoring data. The processor, display, and memory of the third-party device may also include functions not possessed by the processor 120, display 110, and memory of the monitoring device 100. For example, the processor of the third-party device may receive and process monitoring data directly sent by different monitoring devices 100 through communication modules.

[0087] It should be understood that, Figure 1 This is merely an example of the components included in the monitoring device 100 and does not constitute a limitation on the monitoring device 100. Furthermore, the monitoring device 100 may include components beyond those specified in the original text. Figure 1 The monitor may include more or fewer components, or a combination of certain components, or different components. For example, the monitor 100 may also include a power module, a positioning and navigation device, a printing device, etc.

[0088] This application's embodiments are of significant importance for patients undergoing neurosurgical procedures and complex cardiothoracic surgeries. In complex cardiothoracic surgeries, insufficient blood supply to the brain can easily lead to cerebral hypoxia, causing tissue necrosis and irreversible brain damage. Craniotomy involves large blood exchange volumes and is prone to tissue debris; if this debris falls off, it can easily cause infarction. The display interface of this application's embodiments can simultaneously display an anesthesia depth graph representing the real-time anesthesia status, secondary vital signs parameters characterizing brain injury, brain graphics, and parameter trends related to anesthesia depth and brain injury. It focuses on the impact of anesthesia on the brain, thus providing a more professional comprehensive assessment of brain-related monitoring parameters for surgeries on patients with special brain injuries and for surgical types of major cardiothoracic surgeries prone to secondary brain injury complications. By combining parameter trends with intuitive anesthesia depth graphs and intuitive brain graphics, users can promptly identify potential brain damage.

[0089] See Figure 2 The monitoring and evaluation information displayed on the display 110 on its display interface includes at least an anesthesia depth diagram displayed in the first display area 210, a brain graph displayed in the second display area 220, and parameter trends displayed in the third display area 230. Figure 2 In the displayed interface, the first display area 210, the second display area 220, and the third display area 230 are three display areas within the same window. The first display area 210 and the second display area 220 are located on the left side of the window, with the second display area 220 located below the first display area 210; the third display area 230 is located on the right side of the window. In other embodiments, the display interface may also have other layouts, such as displaying a brain graphic above an anesthesia depth diagram; this application embodiment does not limit this.

[0090] The anesthesia depth map is generated based on real-time monitoring data of the first vital signs parameters, and graphically represents the real-time anesthesia status of the target subject. In one embodiment, the real-time anesthesia status includes real-time pain status, real-time sedation status, and real-time muscle relaxation status. The anesthesia depth map graphically represents the real-time pain status, real-time sedation status, and real-time muscle relaxation status of the target subject, providing anesthesiologists with the ability to monitor the anesthesia status in real time during surgery.

[0091] The processor 120 acquires vital signs parameters in real time during the surgery and determines the real-time pain status, sedation status, and muscle relaxation status based on the real-time monitoring data of these parameters, so as to graphically display them through an anesthesia depth graph. The vital signs parameters used to determine the real-time pain status can be heart rate (HR), blood pressure (BP), or a combination of heart rate and blood pressure. Alternatively, the anaphylactic nociception index (ANI) can be used. The ANI measures autonomic nerve activity by analyzing the high-frequency components of heart rate variability in real time, thus reflecting the balance between analgesia and nociceptive stimuli. It is more sensitive to intraoperative nociceptive stimuli than indicators such as heart rate and blood pressure. The vital signs parameters used to determine the real-time sedation status include the bispectral index (BIS). The BIS reflects the excitation or inhibition state of the cerebral cortex and sedation / hypnosis information, and can effectively monitor the sedative component within the depth of anesthesia, thereby determining the sedation status. The primary vital signs parameters used to determine real-time muscle relaxation status include TOF (Train-of-four Ratio).

[0092] See also Figure 2 The anesthesia depth diagram used to display real-time anesthesia status can be implemented in the form of an "anesthesia balance triangle," specifically including three indicator bars arranged in a triangular pattern around the same central point. Each indicator bar represents a dimension of real-time anesthesia status. The three indicator bars represent real-time analgesia, real-time sedation, and real-time paralysis, respectively, and the type of real-time anesthesia status corresponding to each indicator bar is labeled nearby. Figure 2 In the example, the background color of the indicator bar is gray, and the proportion of the indicator bar filled with other colors represents the corresponding anesthesia state. The three indicator bars corresponding to the real-time pain state, real-time sedation state, and real-time muscle relaxation state can also be arranged in other ways, such as in parallel; and the shape of the indicator bars is not limited to rectangles, but can be any shape other than rectangles.

[0093] Furthermore, the processor 120 is also configured to control the display 110 to display values ​​of real-time monitoring data for determining the real-time pain state, real-time sedation state, and real-time muscle relaxation state of the target object in the area surrounding the anesthesia depth diagram. In some embodiments, each indicator bar also displays a marker representing a threshold for the corresponding first vital sign parameter, so that the user can determine whether the first vital sign parameter corresponding to the indicator bar is within the normal threshold range.

[0094] Continue to refer to Figure 2 The second display area 220 of the display interface displays a brain image and at least one second vital sign parameter used to characterize brain injury. Exemplarily, the second vital sign parameter includes at least one of the following: electroencephalogram (EEG) related parameters, cerebral blood flow related parameters, cerebral oxygenation related parameters, and cerebrovascular resistance related parameters.

[0095] Among the EEG-related parameters, at least the bispectral index (BIS) is included, but not limited to, the BIS. The BIS includes the left hemisphere BIS-L and the right hemisphere BIS-R. The BIS primarily reflects the excitation or inhibition state of the cerebral cortex and information on sedation and hypnosis. It can effectively monitor the sedative component within the depth of anesthesia; an appropriate depth of anesthesia is beneficial for patient perioperative safety and reduces postoperative complications.

[0096] Cerebral blood flow-related parameters include, but are not limited to, intracranial pressure (ICP), cerebral perfusion pressure (CPP), and mean arterial pressure (MAP). ICP is the pressure exerted by the contents of the cranial cavity on the cranial walls. When intracranial venous return is obstructed or excessive perfusion occurs, cerebral blood flow increases, leading to increased intracranial blood volume and consequently, elevated intracranial pressure. Monitoring ICP can detect conditions such as traumatic brain injury, cerebral hemorrhage, and hydrocephalus. The brain, containing brain tissue, blood, and cerebrospinal fluid, has its own intracranial pressure. Arteries must overcome this pressure to ensure blood reaches brain cells; the difference between arterial pressure and intracranial pressure is CPP, thus characterizing whether normal cerebral blood supply is maintained. MAP is the cyclic average of cardiac arterial blood pressure during each cardiac cycle. MAP affects cerebral blood flow; when mean arterial pressure is too low, blood pressure flowing through the heart decreases, reducing blood circulation and potentially causing insufficient cerebral blood supply. Therefore, MAP indirectly reflects cerebral blood flow.

[0097] Brain oxygenation-related parameters include, but are not limited to, brain oxygen saturation (rSO2). Brain tissue is particularly sensitive to hypoxia; even short-term hypoxia can cause irreversible damage to the central nervous system. Real-time monitoring and timely intervention of brain oxygen saturation can reduce the probability of stroke in patients during or after surgery.

[0098] Parameters related to cerebrovascular resistance include, but are not limited to, end-tidal carbon dioxide concentration (EtCO2). Blood CO2 is an important factor regulating cerebral blood flow; CO2 can relax smooth muscle. When the partial pressure of CO2 increases, vascular smooth muscle cells relax, and cerebral blood flow velocity increases; when the partial pressure of CO2 decreases, cerebral resistance vessels constrict, and blood flow velocity decreases. When cerebrovascular disease occurs, these autoregulatory functions are reduced or lost; therefore, EtCO2 can effectively assess cerebrovascular resistance.

[0099] exist Figure 2 The display interface shows the following secondary vital signs parameters around the brain image: EtCO2, rSO2-1, rSO2-2, BIS-R, BIS-L, MAP, and CPP. The real-time monitoring data of these secondary vital signs parameters are displayed in the area surrounding the brain image. For example, the real-time monitoring data of these secondary vital signs parameters are displayed near the corresponding locations on the brain image. For instance, BIS-R is displayed near the right brain, BIS-L near the left brain, and MAP and CPP near blood vessels, etc., to indicate to the user the location in the brain tissue corresponding to each secondary vital sign parameter.

[0100] For example, the brain graphic can also dynamically change in response to changes in real-time monitoring data of the second vital sign parameters. These dynamic changes can take forms including, but are not limited to, color changes, thickness variations, highlighting, and the display of indicator icons. For instance, if the target object's MAP (metastatic arterial pressure) increases, the blood vessels in the brain graphic will thicken to alert the user to increased pressure from blood flow on the vessel walls. Conversely, when the blood vessels in the brain graphic thin, it indicates decreased pressure from blood flow on the vessel walls.

[0101] Furthermore, the brain graphics are also used to output early warning information. Specifically, the processor 120 can determine whether the real-time monitoring data of the second vital sign parameters meet the preset early warning conditions. When it is determined that the real-time monitoring data of the second vital sign parameters meet the early warning conditions, the control display 110 outputs early warning information through the brain graphics to prompt the user to perform timely manual intervention.

[0102] For example, the processor 120 determines that the real-time monitoring data of the second vital sign parameter meets the warning conditions when at least one of the following conditions is met: the real-time monitoring data of at least one second vital sign parameter is within a preset warning range; and a brain injury state is present in the target object's brain state. The brain state is determined based on the real-time monitoring data of at least two second vital sign parameters. An alarm triggered based on the real-time monitoring data of the second vital sign parameter being within the preset warning range can be called a parameter alarm, and an alarm triggered based on the presence of a brain injury state can be called a state alarm. State alarms can promptly identify a brain injury state even when a single vital sign parameter does not enter the warning range, avoiding missed alarms.

[0103] Furthermore, if the processor 120 determines that the real-time monitoring data of the second vital sign parameter contains a second target vital sign parameter within a preset warning range, it can also control the display 110 to highlight the target monitoring area corresponding to the second target vital sign parameter in the brain image. By highlighting the target monitoring area, medical staff can quickly and intuitively understand the abnormal location in the brain image to carry out corresponding manual intervention, thus improving the work efficiency of medical staff. In addition, the processor 120 can also control the display 110 to highlight the value of the second target vital sign parameter on the display interface. For example, the target monitoring area is determined based on the location of the sensor that collects the second target vital sign parameter. For example, when the bispectral index (BIS-L) of the left brain is within a preset warning range, the location corresponding to the left brain of the target object can be highlighted in the brain image.

[0104] For example, the above-mentioned highlighting includes a combination of one or more of the following methods: highlighting, flashing, color changing, adding prompts, changing transparency, changing background color, changing font, and enlarging size of the value of the target monitoring site or second vital sign parameter.

[0105] The brain graphic in this application embodiment can be specifically implemented as a three-dimensional virtual brain graphic. In some embodiments, the user can rotate the brain graphic to display it from different angles and orientations. For example, Figure 2 The displayed brain graphic shows the forebrain portion, which can be rotated to show the hindbrain portion when a user rotates it. Rotation commands include, but are not limited to, at least one of the following: single click, long press, double click, swipe, flick, preset swipe trajectory, and multi-touch.

[0106] The processor 120 is also configured to control the display 110 to display, in the third display area 230 of the display interface, the parameter trends of at least a portion of the first and second vital sign parameters. The parameter trend specifically refers to the parameter trend of a vital sign parameter within a preset time range from a historical moment to the current moment; for example, the parameter trend could be the parameter trend within two hours prior to the current moment. Exemplarily, the parameter trends of multiple vital sign parameters share the same time axis and are aligned in the time dimension to represent the parameter trends of multiple vital sign parameters within the same time range. Exemplarily, the parameter trend of a vital sign parameter includes a parameter trend curve formed based on real-time monitoring data and monitoring data over a past period, and a threshold baseline corresponding to a preset threshold value of the real-time monitoring data. Users can refer to the threshold baseline to determine whether the vital sign parameter has exhibited abnormalities over a past period. The processor 120 can also adjust the preset threshold and its corresponding threshold baseline in response to a received adjustment command for the preset threshold.

[0107] Figure 2 The displayed parameter trends include the following vital sign parameters: HR (heart rate) / PR (pulse rate), Art (arterial pressure) / NIBP (non-invasive blood pressure), EtCO2, rSO2, BIS-L, and DSA. HR, PR, Art, and NIBP are primary vital sign parameters used to characterize the depth of anesthesia, while EtCO2, rSO2, BIS-L, and DSA are secondary vital sign parameters used to characterize brain injury. For example, the parameter trends displayed in the third display area 230 may include the parameter trends of all primary vital sign parameters used to characterize the depth of anesthesia, and the parameter trends of all secondary vital sign parameters used to characterize brain injury. The parameter trends displayed in the third display area 230 can also be the parameter trends of some of the vital signs parameters. For example, the third display area 230 can support the simultaneous display of parameter trends of up to six vital signs parameters, which can be the default selection of the monitoring device 100; or, it can provide a list of all vital signs parameters in the first and second vital signs parameters, and determine the vital signs parameters whose parameter trends need to be displayed based on the received selection instruction for the vital signs parameters in the list.

[0108] The parameter trends of multiple vital signs can be sorted using the default sorting method, for example, due to Figure 2 In the display interface, the anesthesia depth diagram is shown above the brain image. Therefore, the primary vital sign parameter representing the anesthesia depth is displayed by default above the secondary vital sign parameter representing brain injury for easy comparison by the user. Alternatively, the sorting method of the parameter trends of multiple vital signs can be customized by the user.

[0109] Furthermore, the same vital sign parameters displayed in different locations on the display interface can be displayed in the same style, specifically including at least one of the following: color, font, font size, font style, font effect, font background color, or transparency. For example, for rSO2, the real-time monitoring data values ​​of rSO2 are displayed around the brain image, and the parameter trend of rSO2 is displayed in the parameter trend display area. Optionally, the real-time waveform of rSO2 is also displayed in other areas of the display interface. The real-time monitoring data values ​​of rSO2, the parameter trend curve, and the real-time waveform curve can be displayed in the same color, such as blue, so that users can quickly obtain all information about rSO2 on the display interface.

[0110] In some embodiments, when a selection instruction is received for one of the following information: the value, parameter trend, and real-time waveform of real-time monitoring data for any vital sign parameter, other information can be highlighted to further help the user quickly browse relevant information about that vital sign parameter. For example, when a selection instruction is received for the value of real-time monitoring data around an anesthesia depth indicator or a brain image, the parameter trend of the selected vital sign parameter can be highlighted, and vice versa.

[0111] Furthermore, when any vital sign parameter becomes abnormal, such as when the data of the first or second vital sign parameter falls within a preset warning range, the parameter trend of the vital sign parameter within the warning range can be highlighted. If the statistical value of a vital sign parameter is within a preset warning range over a period of time, the corresponding interval in the parameter trend can be highlighted to indicate to the user the time period during which the vital sign parameter became abnormal.

[0112] For example, the processor 120 is also configured to control the display 110 to highlight the closed region jointly enclosed by the parameter trend curve and the threshold baseline, the area of ​​which may be referred to as the area under the curve (AUC). The size of the closed region jointly enclosed by the parameter trend curve and the threshold baseline can reflect the degree of abnormality of the vital sign parameter. For example, highlighting includes one or more of the following methods: highlighting, flashing, changing color, adding a cue, changing transparency, and changing the background color of the closed region.

[0113] For example, processor 120 can control display 110 to display the area of ​​the closed region formed by the parameter trend curve of real-time monitoring data of cerebral oxygen saturation within a preset time period and the corresponding threshold baseline. Processor 120 can also control display to highlight the closed region formed by the parameter trend curve of real-time monitoring data of cerebral oxygen saturation and the corresponding threshold baseline, for example, by filling it with red. Exemplarily, the second parameter threshold used to calculate AUC is different from the first parameter threshold used for parameter alarm; for example, the second threshold is 85% of the first parameter threshold. When cerebral oxygen saturation is higher than the first parameter threshold, a warning message is generated; when cerebral oxygen saturation is higher than the second parameter threshold but has not reached the first parameter threshold, AUC calculation begins. The size of the closed region corresponding to cerebral oxygen saturation can reflect the degree of blood flow obstruction. When this area exceeds the threshold, a warning message can be generated even if cerebral oxygen saturation has not reached the first parameter threshold.

[0114] In some embodiments, when the trend of vital signs parameters is represented as a trend line, the trend line includes monitoring data from the past period (historical data) and current real-time monitoring data. The processor 120 can control the provision of a time selection control on the trend line. The processor 120 can receive operations on the time selection space on the trend curve, determine the selected specific time, and control the first and second display areas to update to display the anesthesia depth indicator and / or vital signs parameter values ​​corresponding to the selected time point based on the selected time. Further, if an abnormal event occurs corresponding to the selected time point, the monitoring site corresponding to the abnormal vital signs at the selected time point can be displayed on the brain graph. When the time selection control is located in the real-time portion of the trend graph, for example, on the far right of the diagram, the anesthesia depth indicator in the first display area and the vital signs parameter values ​​in the second display area are updated in real-time accordingly.

[0115] In some embodiments, the processor 120 is further configured to control the display 110 to display operation control icons representing monitoring and evaluation information on the monitoring interface. The processor 120 is also configured to respond to a preset operation on the operation control icons, controlling the display 110 to display the monitoring and evaluation information. That is, in a normal monitoring interface, the user can select the operation control icons representing monitoring and evaluation information to display monitoring and evaluation information, such as the anesthesia depth diagram, brain graphics, and parameter trends, as described above, on the display interface.

[0116] The monitoring interface displays the target object's routine vital signs parameters. Specifically, the information displayed on the monitoring interface includes at least the real-time values ​​of the target object's vital signs parameters, the real-time waveforms of the target object's vital signs parameters, the target object's personal information, and operation control icons. (See also...) Figure 2The monitoring interface includes a status bar 240, a menu bar 250, and a taskbar 260 located between the status bar 240 and the menu bar 250. The status bar 240 is displayed at the top of the monitoring interface, showing the target object's personal information, and may also display network identification icons, battery level icons, monitoring type icons, etc. The menu bar 250 is displayed at the bottom of the monitoring interface, showing operation control icons that users can interact with to adjust the content displayed on the monitoring interface. The taskbar 260 displays key monitoring information such as real-time values ​​and waveforms of the target object's vital signs. The taskbar 260 is positioned in the center of the monitoring interface for easy user observation and operation.

[0117] For example, monitoring and evaluation information can be displayed as follows: Figure 2 In the BoA Dashboard (brain protection) window shown, when the BoA Dashboard window pops up, the real-time waveforms and other information of the target vital signs parameters in the monitoring interface are displayed in a reduced size to reserve display space for the BoA Dashboard window and avoid obscuring the original information. Users can click the close option in the upper right corner of the BoA Dashboard window to close it. In some embodiments, the monitoring and evaluation information, exemplified by the BoA Dashboard, can also partially obscure the information in the monitoring interface and be displayed directly overlaid on the monitoring interface.

[0118] In some embodiments, the processor 120 is also configured to adjust portions of the monitoring and evaluation information other than the brain image in response to a received operation command. For example, the processor 120 may cancel the display of the anesthesia depth diagram or the display of the parameter trends of vital signs.

[0119] In summary, the monitoring device 100 of this application embodiment simultaneously displays an anesthesia depth diagram representing the real-time anesthesia status and a brain graph representing brain injury-related parameters on the display interface. The anesthesia depth diagram can be provided to the anesthesiologist to macroscopically control the patient's anesthesia status during surgery; the brain graph and brain injury-related vital sign parameters can be provided to the surgeon to more comprehensively assess the patient's brain-related feedback during surgery. It has outstanding comprehensive assessment advantages for patients undergoing craniocerebral neurosurgery and complex cardiothoracic surgery.

[0120] Below, we will refer to Figure 3 This application describes a display method for a monitoring device according to one embodiment. Figure 3 This is a schematic flowchart of a display method 300 for a monitoring device according to an embodiment of this application.

[0121] like Figure 3 As shown, the display method 300 for a monitoring device according to an embodiment of this application includes the following steps:

[0122] In step S310, real-time monitoring data of at least two vital signs parameters of the target object are obtained. The at least two vital signs parameters include at least one first vital sign parameter used to characterize the depth of anesthesia and at least one second vital sign parameter used to characterize brain injury.

[0123] In step S310, monitoring and evaluation information is displayed on the display interface. The monitoring and evaluation information includes: an anesthesia depth diagram generated based on real-time monitoring data of the first vital sign parameter, which graphically represents the real-time anesthesia state of the target object; a brain image, with the values ​​of the real-time monitoring data of the second vital sign parameter displayed in the surrounding area of ​​the brain image; and the parameter trends of at least some of the vital sign parameters, including the first vital sign parameter and the second vital sign parameter.

[0124] The display method 300 for a monitoring device in this embodiment can be implemented in the monitoring device 100 described above. Specifically, the processor 120 of the monitoring device 100 can execute the steps of the display method 300. Specific details of the display method 300 for a monitoring device can be found in the above description of the monitoring device 100, and will not be repeated here.

[0125] Another aspect of this application provides a monitoring device, which includes a display and a processor. The processor is configured to: acquire real-time monitoring data of at least two vital signs parameters of a target object, the at least two vital signs parameters including at least one first vital sign parameter for characterizing the depth of anesthesia and at least one second vital sign parameter for characterizing brain injury; control the display to display monitoring and evaluation information on its display interface, the monitoring and evaluation information including: an anesthesia depth indication generated based on the real-time monitoring data of the first vital sign parameter, the anesthesia depth indication representing the real-time anesthesia status of the target object; a centrally displayed value of the real-time monitoring data of the second vital sign parameter; and a parameter trend of at least some of the first and second vital sign parameters.

[0126] The monitoring device in this embodiment is similar to the monitoring device described above. The main differences are as follows: First, the anesthesia depth indicator displayed by the monitoring device in this embodiment is not limited to the form of an anesthesia depth diagram. For example, the anesthesia depth can also be presented in text form after analyzing the first vital sign parameters to obtain the anesthesia status. Second, the monitoring device in this embodiment is not limited to displaying brain graphics while displaying the anesthesia depth indicator. For example, it can focus on displaying only at least one second vital sign parameter used to characterize brain injury to present the brain status of the target subject.

[0127] For example, the real-time anesthesia state includes real-time pain state, real-time sedation state, and real-time muscle relaxation state; the anesthesia depth indicator represents the target subject's real-time pain state, real-time sedation state, and real-time muscle relaxation state, and the representation method may include graphical or textual representation. While displaying the anesthesia depth indicator, the processor is also used to control the display to show the values ​​of real-time monitoring data of the first vital sign parameters used to determine the target subject's real-time pain state, real-time sedation state, and real-time muscle relaxation state. For example, the processor can determine the real-time pain state based on heart rate, blood pressure, a combination of heart rate and blood pressure, or a nociceptive stress index, and while displaying the real-time pain state, it can also display the values ​​of the real-time monitoring data of the aforementioned parameters used to determine the real-time pain state.

[0128] For example, the second vital sign parameters include at least one of the following categories: electroencephalogram (EEG) related parameters, cerebral blood flow related parameters, cerebral oxygenation related parameters, and cerebrovascular resistance related parameters. Among these, EEG related parameters include the bispectral index; cerebral blood flow related parameters include intracranial pressure, cerebral perfusion pressure, and mean arterial pressure; cerebral oxygenation related parameters include cerebral oxygen saturation; and cerebrovascular resistance related parameters include end-tidal carbon dioxide concentration. For example, the processor is further configured to determine, from the real-time monitoring data of the second vital sign parameters, a second target vital sign parameter that falls within a preset warning range, and control the display to highlight the value of the second target vital sign parameter on the display interface.

[0129] The display shows the parameter trends of vital signs, including parameter trend curves and threshold baselines corresponding to preset thresholds in the real-time monitoring data of the vital signs. The processor also controls the display to highlight the closed area enclosed by the parameter trend curves and the threshold baselines.

[0130] More specific details regarding the monitoring equipment can be found above and will not be repeated here. The monitoring equipment in this embodiment simultaneously displays an anesthesia depth indicator to represent the real-time anesthesia status, as well as vital signs parameters related to brain injury on the display interface. The anesthesia depth indicator can macroscopically present the patient's anesthesia status during surgery; the vital signs parameters related to brain injury can provide more comprehensive feedback on the patient's brain during surgery.

[0131] Below, we will refer to Figure 4 This application describes a display method for a monitoring device according to one embodiment. Figure 4 This is a schematic flowchart of a display method 400 for a monitoring device according to an embodiment of this application.

[0132] like Figure 4 As shown, the display method 400 for a monitoring device according to an embodiment of this application includes the following steps:

[0133] In step S410, real-time monitoring data of at least two vital signs parameters of the target object are obtained. The at least two vital signs parameters include at least one first vital sign parameter used to characterize the depth of anesthesia and at least one second vital sign parameter used to characterize brain injury.

[0134] In step S410, monitoring and evaluation information is displayed on the display interface. The monitoring and evaluation information includes: an anesthesia depth indication generated based on real-time monitoring data of the first vital sign parameter, the anesthesia depth indication representing the real-time anesthesia status of the target object; the numerical values ​​of real-time monitoring data of the second vital sign parameter displayed centrally; and the parameter trends of at least some of the vital sign parameters among the first vital sign parameter and the second vital sign parameter.

[0135] The display method 400 for a monitoring device in this embodiment can be implemented in the monitoring device described above. Specifically, the processor of the monitoring device can execute the steps of the display method 400. Specific details of the display method 400 for a monitoring device can be found in the relevant description of the monitoring device above, and will not be repeated here.

[0136] Another embodiment of this application provides a monitoring device, which includes a display and a processor. The processor is configured to: acquire real-time monitoring data of at least two vital sign parameters of a target object, the at least two vital sign parameters including at least one first vital sign parameter for characterizing the depth of anesthesia and at least one second vital sign parameter for characterizing brain injury; and, in response to a first preset operation of a first operation control, control the display to display a first monitoring and evaluation window on its display interface, the first monitoring and evaluation window being configured to display first monitoring and evaluation information, the first monitoring and evaluation information including: an anesthesia depth diagram generated based on the real-time monitoring data of the first vital sign parameters, the anesthesia depth diagram graphically representing the real-time anesthesia state of the target object; and a brain image, the second vital sign parameter, etc. The values ​​of real-time monitoring data of vital signs are centrally displayed in the area surrounding the brain image; and the parameter trends of at least some of the first and second vital signs parameters; and, in response to a second preset operation on the second operation control, the display is controlled to display a second monitoring and evaluation window on its display interface, the second monitoring and evaluation window being used to display second monitoring and evaluation information, the second monitoring and evaluation information including: an anesthesia depth indication generated based on the real-time monitoring data of the first vital signs parameters, the anesthesia depth indication representing the real-time anesthesia status of the target object; the values ​​of the real-time monitoring data of the second vital signs parameters centrally displayed; and the parameter trends of at least some of the first and second vital signs parameters.

[0137] This application provides two types of monitoring and evaluation windows: the first monitoring and evaluation window displays first monitoring and evaluation information including at least an anesthesia depth diagram, brain graphics, and parameter trends; the second monitoring and evaluation window displays second monitoring and evaluation information including at least anesthesia depth indication, centrally displayed real-time monitoring data values ​​of the second vital sign parameters, and parameter trends. The second vital sign parameters corresponding to the second monitoring and evaluation window are at least partially different from those corresponding to the first monitoring and evaluation window. In one example, the second monitoring and evaluation window corresponds to more types of second vital sign parameters.

[0138] Users can switch between the two monitoring and assessment windows as needed. For example, if a user needs a more intuitive display of brain status, they can operate the first control to display the first monitoring and assessment window; if a user needs to view more vital signs parameters, they can operate the second control to display the second monitoring and assessment window.

[0139] This embodiment provides two types of monitoring and assessment windows. These different windows present the anesthesia and brain injury states in different ways. Users can select the appropriate monitoring and assessment window as needed to achieve real-time monitoring and assessment of the brain's state during surgery. Specific details regarding the two different types of monitoring and assessment windows have been described above and will not be repeated here.

[0140] Below, we will refer to Figure 5 This application describes a display method for a monitoring device according to one embodiment. Figure 5 This is a schematic flowchart of a display method 500 for a monitoring device according to an embodiment of this application.

[0141] like Figure 5 As shown, the display method 500 for a monitoring device according to an embodiment of this application includes the following steps:

[0142] In step S510, real-time monitoring data of at least two vital signs parameters of the target object are obtained. The at least two vital signs parameters include at least one first vital sign parameter used to characterize the depth of anesthesia and at least one second vital sign parameter used to characterize brain injury.

[0143] In step S510, in response to a first preset operation on the first operation control, a first monitoring and evaluation window is displayed on the display interface. The first monitoring and evaluation window is used to display first monitoring and evaluation information, which includes: an anesthesia depth diagram generated based on real-time monitoring data of the first vital sign parameters, the anesthesia depth diagram representing the real-time anesthesia state of the target object in a graphical manner; a brain image, the values ​​of the real-time monitoring data of the second vital sign parameters being concentrated in the surrounding area of ​​the brain image; and the parameter trends of at least some of the vital sign parameters among the first and second vital sign parameters.

[0144] In step S530, in response to a second preset operation on the second operation control, a second monitoring and evaluation window is displayed on the display interface. The second monitoring and evaluation window is used to display second monitoring and evaluation information, which includes: an anesthesia depth indication generated based on real-time monitoring data of the first vital sign parameters, the anesthesia depth indication representing the real-time anesthesia status of the target object; the numerical values ​​of the real-time monitoring data of the second vital sign parameters displayed centrally; and the parameter trends of at least some of the vital sign parameters among the first and second vital sign parameters.

[0145] The display method 500 for a monitoring device in this embodiment can be implemented in the monitoring device described above. Specifically, the processor of the monitoring device can execute the steps of the display method 500. Specific details of the display method 500 for a monitoring device can be found in the relevant description of the monitoring device above, and will not be repeated here.
