The embodiment of the application has important significance for patients with craniocerebral nerve special surgery and complex cardio-thoracic surgery. In complex cardiothoracic surgery, the deficiency of blood supply to the heart, chest and brain easily causes hypoxia of the brain of a patient, causes tissue necrosis and causes irreversible brain injury; the craniotomy has a large blood change amount, tissue scraps are easy to appear, and if the tissue scraps fall down, the infarct is easy to be caused. The display interface of the embodiment of the application can display the anesthesia depth graphic for representing the real-time anesthesia state, the second vital sign parameter and brain graphic for representing the brain injury, and the parameter trend of the vital sign parameter related to the anesthesia depth and the brain injury on the same screen, and pay attention to the influence of anesthesia on the brain, thereby providing more specialized comprehensive evaluation of brain related monitoring parameters for the operation type of a special brain injury patient operation and a large-scale heart-chest operation, and enabling a user to judge the possible brain injury in time by combining the parameter trend with the visual anesthesia depth graphic and the visual brain graphic.

Referring to fig. 2, the monitoring evaluation information displayed on the display interface of the display 110 includes at least the anesthesia depth map displayed in the first display area 210, the brain map displayed in the second display area 220, and the parameter trend displayed in the third display area 230. In the display interface shown in fig. 2, the first display area 210, the second display area 220, and the third display area 230 are three display areas in the same window, the first display area 210 and the second display area 220 are located on the left side of the window, and the second display area 220 is located below the first display area 210; the third display area 230 is located to the right of the window. In other embodiments, the display interface may have other layouts, such as a brain graphic displayed above an anesthesia depth map, as the embodiments of the present application are not limited in this respect.

Wherein the anesthesia depth map is generated based on the real-time monitoring data of the first vital sign parameter, and graphically represents the real-time anesthesia status of the target object. In one embodiment, the real-time anesthetic state includes a real-time pain state, a real-time sedation state, and a real-time muscle relaxation state. The anesthesia depth map graphically represents the real-time pain state, the real-time sedation state, and the real-time muscle relaxation state of the target subject, which can be provided to an anesthesiologist for real-time monitoring of the intra-operative anesthesia state.

The processor 120 acquires the first vital sign parameters in real time during the surgical procedure and determines a real-time pain state, a real-time sedation state, and a real-time muscle relaxation state from the real-time monitoring data of the first vital sign parameters for graphical display thereof via the anesthesia depth map. The first vital sign parameter used to determine the real-time pain state may be Heart Rate (HR), blood Pressure (BP), or a combination of Heart Rate and Blood Pressure, among others. Alternatively, the first vital sign parameter used to determine the real-time pain state may be a nociceptive stimulation index (Aanalgesia Nociception Index, ANI). ANI is an index that measures autonomic nerve activity by analyzing high frequency components in heart rate variability on-line in real time, thereby reflecting the balance between analgesic and nociceptive stimuli, and is more sensitive to the responses of intraoperative nociceptive stimuli than to heart rate, blood pressure, and other indexes. The first vital sign parameters for determining the real-time sedation state include brain electrical double frequency index (BIS) which can reflect the excitation or inhibition state of cerebral cortex and the sedative hypnotic information, and can monitor the sedation component in the anesthesia depth well, thereby determining the sedation state. The first vital sign parameters for determining the real-time muscle relaxation state include TOF (Train-of-four serial stimuli).

With continued reference to fig. 2, the anesthesia depth map for displaying real-time anesthesia status may be implemented in the form of an "anesthesia balance triangle", specifically including three indicator bars arranged in a triangle line around the same center point, each indicator bar being used to represent a real-time anesthesia status in one dimension, the three indicator bars respectively representing a real-time pain status (Analgesia), a real-time Sedation status (session), and a real-time muscle relaxation status (analysis), and each indicator bar being labeled with a type of real-time anesthesia status corresponding to the indicator bar in the vicinity thereof. In the example of fig. 2, the background color of the indicator strip is gray, and the proportion of the indicator strip filled with the other color represents the corresponding anesthetic state. Other arrangements of the three indicators corresponding to the real-time pain state, the real-time sedation state, and the real-time muscle relaxation state, such as a parallel arrangement, may also be used; the shape of the indicator strip is not limited to a rectangle, and may be any shape other than a rectangle.

Further, the processor 120 is further configured to control the display 110 to display values of the real-time monitoring data for determining the first vital sign parameters of the real-time pain state, the real-time sedation state and the real-time muscle relaxation state of the target subject in the surrounding area of the anesthesia depth map. In some embodiments, a marker representing a threshold value for the corresponding first vital sign parameter is also displayed in each indicator strip to facilitate a user's determination of whether the first vital sign parameter corresponding to the indicator strip is within a normal threshold range.

With continued reference to fig. 2, a brain graphic and at least one second vital sign parameter for characterizing a brain injury are displayed in a second display area 220 of the display interface. Illustratively, the second vital sign parameter comprises at least one of the following: brain electrical related parameters, brain blood flow related parameters, brain oxygen related parameters, and brain vascular resistance related parameters.

The electroencephalogram related parameters at least include, but are not limited to, an electroencephalogram double index (BIS). The brain electrical double frequency index comprises brain electrical double frequency index (BIS-L) of left brain and brain electrical double frequency index (BIS-R) of right brain. BIS mainly reflects the excitation or inhibition state of cerebral cortex and sedative hypnotic information, can well monitor sedative components in the anesthesia depth, and the appropriate anesthesia depth is beneficial to the perioperative safety of patients and reduces postoperative complications.

The cerebral blood flow related parameters include at least intracranial pressure (Intracranial Pressure, ICP), cerebral perfusion pressure (Cerebral Perfusion Pressure, CPP), mean arterial pressure (mean arterial pressure, MAP), but are not limited thereto. The ICP is the pressure of the content of the cranial cavity on the wall of the cranial cavity, when the back flow of the intracranial vein is blocked or excessively poured, cerebral blood flow is increased, the intracranial blood volume is increased, the intracranial pressure is increased, and the ICP can be monitored to monitor craniocerebral injury, cerebral hemorrhage, hydrocephalus and the like. The brain has brain tissue, blood and cerebrospinal fluid, so that it has a certain intracranial pressure, and the arterial blood vessel must overcome the intracranial pressure to ensure that the blood enters brain cells, and the difference between the arterial pressure and the intracranial pressure is CPP, so that the CPP can be used for representing whether normal cerebral blood supply is maintained or not. MAP is a periodic average value of arterial blood pressure of heart in every cardiac cycle of heart, MAP can influence cerebral blood flow, when average arterial pressure is too low, blood pressure flowing through heart is reduced, blood pressure circulation speed is reduced, cerebral blood supply insufficiency is easily caused, and therefore MAP can indirectly reflect cerebral blood flow.

The brain oxygen related parameter at least comprises brain oxygen saturation (rSO) ₂ ) But is not limited thereto. Brain tissue is especially sensitive to hypoxia, and the hypoxia in a short time can possibly cause unrecoverable damage to the central nervous system, and the brain oxygen saturation is monitored in real time and intervened in time, so that the probability of cerebral apoplexy of a patient in operation or after operation can be reduced.

The cerebrovascular resistance-related parameters include at least end-of-breath carbon dioxide concentration (EtCO ₂ ) But is not limited thereto. CO in blood ₂ Is an important factor for regulating the cerebrovascular blood flow state, and CO ₂ Smooth muscle may relax. When CO ₂ When the partial pressure is increased, vascular smooth muscle cells are relaxed, and the cerebral blood flow speed is increased; when CO ₂ When the partial pressure is reduced, the brain resistance blood vessel contracts, and the blood flow speed is reduced. When cerebral angiogenesis lesions, these autoregulation functions are reduced or lost, and thus EtCO ₂ Can effectively evaluate the cerebrovascular resistance.

In the display interface of fig. 2, the second vital sign parameters displayed around the brain graphic include the following: etCO ₂ 、rSO ₂ -1、rSO ₂ -2, BIS-R, BIS-L, MAP and CPP. Values of the real-time monitoring data of the second vital sign parameter are displayed in a surrounding area of the brain pattern. Illustratively, the values of the real-time monitoring data of the second vital sign parameter are displayed in the vicinity of the corresponding location of the brain pattern. For example, BIS-R is displayed near the right brain, BIS-L is displayed near the left brain, MAP and CPP are displayed near blood vessels, etc., to prompt the user for locations in brain tissue corresponding to the respective second vital sign parameters.

Illustratively, the brain graphic may also dynamically change as the real-time monitoring data of the second vital sign parameter changes, the form of the dynamic change including, but not limited to, a color change, a thickness change, highlighting, displaying an indicator icon, and the like. For example, if the MAP of the target object increases, the blood vessels in the brain pattern will thicken to alert the user to the increased pressure of the blood flow of the target object against the vessel wall. Conversely, when a blood vessel in the brain pattern becomes thin, it is indicated that the blood flow of the target subject is reduced in pressure against the vessel wall.

Further, the brain pattern is also used for outputting early warning information. Specifically, the processor 120 may determine whether the real-time monitoring data of the second vital sign parameter meets a preset early warning condition, and when determining that the real-time monitoring data of the second vital sign parameter meets the early warning condition, control the display 110 to output early warning information through the brain pattern, so as to prompt the user to perform the manual intervention in time.

Illustratively, the processor 120 determines that the real-time monitoring data of the second vital sign parameter satisfies the pre-warning condition when it is determined that at least one of the following conditions is satisfied: the real-time monitoring data of at least one second vital sign parameter is in a preset early warning range; and, a brain damage state occurs in the brain state of the target subject. Wherein the brain state is determined from real-time monitoring data of at least two second vital sign parameters. The alarm triggered according to the fact that the real-time monitoring data of the second vital sign parameters are in a preset early warning range can be called parameter alarm, and the alarm triggered according to the brain damage state of the brain state can be called state alarm. The state alarm can timely identify the brain damage state when the individual vital sign parameters do not enter the early warning range, so that the occurrence of missing alarm is avoided.

Further, if the processor 120 determines that the second target vital sign parameter within the preset pre-warning range exists in the real-time monitoring data of the second vital sign parameter, the display 110 can be controlled to highlight the target monitoring portion corresponding to the second target vital sign parameter in the brain graph, and by highlighting the target monitoring portion, the medical care can quickly and intuitively learn about the abnormal position in the brain graph so as to perform corresponding manual intervention, thereby improving the working efficiency of the medical care personnel. The processor 120 may further control the display 110 to highlight the value of the second target vital sign parameter on the display interface. The target monitoring site is illustratively determined from the location of a sensor that acquires a second target vital sign parameter. For example, when the brain electrical double frequency index (BIS-L) of the left brain is in a preset early warning range, a position corresponding to the left brain of the target object in the brain pattern may be highlighted.

Illustratively, the highlighting includes a combination of one or more of highlighting, blinking, changing color, adding a reminder, changing transparency, changing background color, changing font, enlarging the size of the target monitoring site or the value of the second vital sign parameter.

The brain graphic of the embodiment of the application can be specifically realized as a three-dimensional virtual brain graphic, and in some embodiments, a user can rotate the brain graphic so as to display the brain graphic in different angular orientations. For example, the brain graphic shown in fig. 2 presents an anterior brain portion that can be rotated to present a posterior brain portion when a user rotation command is received. The rotation instruction includes, but is not limited to, at least one of a single click, a long press, a double click, a slide, a toggle, a preset slide track, and a multi-touch.

The processor 120 is further configured to control the display 110 to display the parameter trend of at least some of the first vital sign parameter and the second vital sign parameter in the third display area 230 of the display interface. Parameter trend the specific vital sign parameter is a parameter trend within a preset time range from the historical moment to the current moment, for example, the parameter trend may be a parameter trend within 2 hours before the current moment. Illustratively, the parameter trends of the plurality of vital sign parameters share a same time axis and are displayed in alignment in a time dimension to represent the parameter trends of the plurality of vital sign parameters within the same time range. Illustratively, the parameter trend of the vital sign parameter includes a parameter trend curve formed based on the real-time monitoring data and the monitoring data over a period of time in the past, and a threshold baseline of a preset threshold corresponding to the real-time monitoring data, and the user can determine whether the vital sign parameter has been abnormal over the period of time in the past with reference to the threshold baseline. The processor 120 may also adjust the preset threshold and its corresponding threshold baseline in response to receiving an adjustment instruction to the preset threshold.

The parameter trends shown in fig. 2 include the parameter trends of the vital sign parameters: HR (heart rate)/PR (pulse rate), art (arterial pressure)/NIBP (non-invasive blood pressure), etCO ₂ 、rSO ₂ BIS-L, DSA. Wherein HR, PR, art, NIBP is a first vital sign parameter for characterizing depth of anesthesia, etCO ₂ 、rSO ₂ BIS-L, DSA is a second vital sign parameter used to characterize brain damage. Illustratively, the parameter trends displayed in the third display area 230 may include a parameter trend for characterizing all first vital sign parameters of the depth of anesthesia, and a parameter trend for characterizing all second vital sign parameters of the brain injury. The parameter trend displayed in the third display area 230 may also be a parameter trend of a portion of the vital sign parameters therein, e.g., the third display area 230 supports at most simultaneous display of parameter trends of six vital sign parameters, which may be selected by default by the monitoring device 100; or, a list of all vital sign parameters in the first vital sign parameter and the second vital sign parameter may be provided, and the vital sign parameter of which parameter trend needs to be displayed is determined according to the received selection instruction of the vital sign parameters in the list.

The parameter trends of the plurality of vital sign parameters may be ordered by default, for example, because the anesthesia depth graphic is displayed above the brain graphic in the display interface of fig. 2, the first vital sign parameter characterizing the anesthesia depth is displayed above the second vital sign parameter characterizing the brain injury by default to facilitate a user's control view. Alternatively, the ordering of the parameter trends for the plurality of vital sign parameters may be user-defined.

In addition, the vital sign parameters of the same kind displayed at different positions on the display interface may be displayed in the same style, specifically including at least one of the same color, font size, font style, font effect, font background color or transparency. For exampleFor rSO ₂ For example, rSO is displayed around the brain pattern ₂ Is displayed with rSO in the display area of parameter trend ₂ Optionally, rSO is also displayed in other areas of the display interface ₂ Is a real-time waveform of (a). rSO ₂ The values of the real-time monitoring data, the curves of the parameter trend and the curves of the real-time waveform can be displayed in the same color, such as blue, so that a user can quickly obtain information on rSO in a display interface ₂ Is a piece of information of the whole information.

In some embodiments, when a selection instruction of one of the numerical value, the parameter trend, and the real-time waveform of the real-time monitoring data of any vital sign parameter is received, other information may be highlighted to further help the user quickly browse the relevant information of the vital sign parameter. For example, when a selection instruction for the anesthesia depth indication or the value of the real-time monitoring data around the brain pattern is received, the parameter trend of the selected vital sign parameter may be highlighted, and vice versa.

In addition, when any vital sign parameter is abnormal, for example, when the parameter data of the first vital sign parameter or the second vital sign parameter is within a preset early warning range, the parameter trend of the vital sign parameter within the early warning range may be highlighted. If the statistical value of the vital sign parameter in a period of time is in a preset early warning range, a corresponding interval in the parameter trend can be highlighted to prompt a user of a period of time when the vital sign parameter is abnormal.

The processor 120 is also configured to control the display 110 to highlight, for example, a closed Area formed by the co-surrounding of the parameter trend Curve and the threshold baseline, and the Area of the closed Area may be referred to as Area Under the Curve (AUC). The size of the area of the enclosed area formed by the coarticulation between the parameter trend curve and the threshold value base line can reflect the abnormal degree of vital sign parameters. Illustratively, highlighting includes one or more of highlighting, blinking, changing color, adding a reminder, changing transparency, changing background color.

For example, the processor 120 may control the display 110 to display the area of the enclosed area defined by the parameter trend curve of the real-time monitoring data of the brain oxygen saturation within the preset time period and the corresponding threshold baseline. The processor 120 may also control the display to highlight a closed area formed by co-enclosing a parameter trend curve of the real-time monitoring data of brain oxygen saturation and a corresponding threshold baseline, for example, to perform red filling. Illustratively, the second parameter threshold for calculating AUC is different from the first parameter threshold for parameter alerting, e.g., the second threshold is 85% of the first parameter threshold, and when brain oxygen saturation is higher than the first parameter threshold, generating the pre-warning information; when the brain oxygen saturation is above the second parameter threshold, but does not reach the first parameter threshold, the AUC is calculated. The size of the closed region corresponding to the cerebral oxygen saturation can reflect the degree of blood flow blocking, and when the area exceeds the threshold value, even if the cerebral oxygen saturation does not reach the first parameter threshold value, early warning information can be generated.

In some embodiments, when the parameter trend of the vital sign parameter is embodied as a parameter trend line, the parameter trend line includes monitoring data (historical data) over a period of time and current real-time monitoring data. The processor 120 may control providing a time selection control on the parameter trend line, the processor 120 may receive an operation on the time selection space on the parameter trend line, determine a specific time selected, and control updating values of anesthesia depth indicators and/or vital sign parameters corresponding to the selected time point in the first display area and the second display area according to the selected time. Further, if the abnormal event occurs corresponding to the selected time point, the monitoring part corresponding to the abnormal vital sign at the selected time point can be displayed on the brain graph. The anesthesia depth indication of the first display area and the value of the vital sign parameter of the second display area are refreshed in real time when the time selection control is located in the real-time portion of the parameter trend graph, e.g., at the far right side of the graph.

In some embodiments, the processor 120 is further configured to control the display 110 to display an operational control icon representing monitoring assessment information on the monitoring interface. The processor 120 is further configured to control 110 the display to display monitoring assessment information in response to a preset operation for operating the control icon. That is, under a conventional monitoring interface, the user may select an icon of an operation control representing monitoring evaluation information to display monitoring evaluation information including anesthesia depth graphic, brain graphic, parameter trend, and the like as described above on the display interface.

The monitoring interface is used for displaying conventional vital sign parameters of the target object, and specifically, the information displayed by the monitoring interface at least comprises real-time numerical values of the vital sign parameters of the target object, real-time waveforms of the vital sign parameters of the target object, personal information of the target object and operation control icons. With continued reference to FIG. 2, the guardian interface includes a status bar 240, a menu bar 250, and a task bar 260 located between the status bar 240 and the menu bar 250. The status bar 240 is displayed on top of the monitoring interface, in which personal information of the target object is displayed, and may also display a network identification icon, a power identification icon, a monitoring type icon, and the like. Menu bar 250 is displayed at the bottom of the monitoring interface for displaying operation control icons that a user can operate to adjust the content displayed by the monitoring interface. The task bar 260 displays main monitoring information such as real-time numerical values of vital sign parameters of the target object, real-time waveforms of the vital sign parameters of the target object, and the like, and the task bar 260 is displayed in the middle of the monitoring interface, so that a user can observe and operate conveniently.

The monitoring evaluation information may be displayed in a BoA Dashboard (brain protection) window as shown in fig. 2, and when the BoA Dashboard window is popped up, information such as a real-time waveform of a target vital sign parameter in the monitoring interface is displayed in a reduced manner, so as to reserve a display space of the BoA Dashboard window, and avoid the BoA Dashboard window from shielding original information. The user may click on the close option at the top right of the BoA Dashboard window to close the BoA Dashboard window. In some embodiments, the monitoring evaluation information, for example, a BoA Dashboard, may also cover a portion of the information on the monitoring interface, and may be directly displayed in an overlaid manner on the monitoring interface.

In some embodiments, processor 120 is further configured to adjust portions of the monitoring assessment information other than the brain pattern in response to the received operational instructions. For example, the processor 120 may cancel the display of the anesthesia depth map, or cancel the display of the parameter trend of the vital sign parameters, etc.
