Description

Technical Field

[0001] The present disclosure relates to the technical field of monitoring equipment, and in particular to an intracranial pressure monitor. Background Art

[0002] Increased intracranial pressure (ICP) can cause serious adverse consequences, which are common in brain diseases such as craniocerebral trauma, intracranial infection, cerebrovascular disease and brain tumors. As an indispensable monitoring device in modern medicine, intracranial pressure monitor plays a vital role in neurosurgery, intensive care and other fields. It can help doctors to timely grasp the changes in physiological parameters such as intracranial pressure of the monitored object through real-time and continuous monitoring. Invasive (invasive) intracranial pressure measurement has always been regarded as the "gold standard" for intracranial pressure monitoring. Accurately monitoring changes in intracranial pressure and reasonably confirming the intracranial pressure intervention threshold are the key to effectively controlling intracranial pressure, reducing mortality and improving neurological prognosis. If the intracranial pressure measurement is inaccurate, it may cause doctors to make wrong decisions, posing a serious threat to the patient's life safety.

[0003] The invasive intracranial pressure monitor measures intracranial pressure and other physiological parameters by connecting to the brain sensor implanted in the skull. Before the brain sensor is implanted in the skull, it is necessary to calibrate the brain sensor to zero pressure. Specifically, the doctor immerses the probe with the brain sensor in standard saline at a specific height for zero point calibration. After the calibration is completed, the probe is implanted into the patient's skull to monitor intracranial pressure. In order to ensure the accuracy of the monitoring results, it is strictly forbidden to calibrate the brain sensor after implanting it in the patient's skull.

[0004] For the existing intracranial pressure monitor, there is usually only one zero-point calibration opportunity for the same brain sensor. However, due to the lack of standardization of the calibration process or the influence of environmental factors, sometimes the zero point is not adjusted, but the monitor does not support the zero-point calibration of the brain sensor again. In this case, the user is accustomed to manually recording the non-zero calibration value, and manually deducting the non-zero calibration value based on the later monitoring results as the patient's intracranial pressure. This method is not only cumbersome, but also causes great inconvenience to clinical intracranial pressure monitoring. What is more serious is that if the zero point is not adjusted for the first time or the non-zero calibration value obtained is large, the non-zero calibration value is unreliable data, and the intracranial pressure measurement data obtained by manually deducting the non-zero calibration value will be distorted and cannot truly reflect the patient's intracranial pressure. Therefore, it is of great significance to effectively calibrate the brain sensor to zero before monitoring so that the intracranial pressure results measured during the monitoring process are accurate. Summary of the invention

[0005] In view of this, the present disclosure proposes an invasive intracranial pressure monitor that can provide multiple zero-point calibration opportunities for the same brain sensor to ensure the accuracy of the zero-point calibration, thereby obtaining accurate intracranial physiological parameters; at the same time, it protects the security of monitoring data and facilitates clinical operations.

[0006] According to one aspect of the present disclosure, an intracranial pressure monitor is provided, comprising a host having a display screen for displaying a user interface, the host being connectable to a brain sensor for implantation in the skull, the brain sensor being used to measure physiological parameters including intracranial pressure, and the host being capable of performing two or more zero-point calibrations for the same brain sensor.

[0007] In this way, the intracranial pressure monitor disclosed in the present invention has multiple zero-point calibration functions for the same brain sensor, so that the measurement basis of the brain sensor is accurate, thereby ensuring the accuracy and reliability of the monitored intracranial pressure value, and is convenient for clinical operation. It can effectively solve the problem of failure of zero-point calibration of the brain sensor in related technologies due to factors such as irregular calibration operation.

[0008] In a possible implementation, the host confirms execution of a first-time zero-point calibration procedure or confirms execution of a non-first-time zero-point calibration procedure in response to a user operation on the user interface.

[0009] In this way, the monitor can provide the user with confirmation operations on the calibration procedure through the user interface, making the calibration process more intuitive and easy to understand, thereby improving the user experience.

[0010] In one possible implementation, the first zero-point calibration is that after the host detects that the connection with the brain sensor is successful, it controls the appearance of a first calibration control on the user interface, and executes the zero-point calibration procedure in response to a trigger operation confirmation for the first calibration control; the user interface has a permanent calibration control, and the non-first zero-point calibration is that the host detects a trigger operation confirmation for the permanent calibration control to execute the non-first zero-point calibration procedure.

[0011] In this way, the user interface of the monitor can display the first calibration controls, allowing the user to intuitively identify and indicate whether to perform the first calibration procedure, thereby improving the convenience of the calibration operation and the friendliness of the user interface; moreover, the user can perform non-first-time zero-point calibration on the brain sensor through the permanent calibration controls to ensure the reliability of the brain sensor use process, thereby obtaining accurate intracranial physiological parameters and facilitating clinical operations.

[0012] In a possible implementation, after the host detects that the permanent calibration control is triggered and before a non-first zero-point calibration procedure is executed, the host issues a calibration operation reminder through a user interface and requires a password to be entered.

[0013] In this way, the monitor reminds users of non-first-time zero-point calibration operations through the user interface, and has encryption settings to prevent accidental zero-point calibration operations from causing loss or confusion of stored data, thereby ensuring the accuracy and security of intracranial pressure monitoring data.

[0014] In a possible implementation, the physiological parameters also include intracranial temperature, the user interface includes a monitoring interface, the monitoring interface includes a first area, a second area, a third area and a fourth area, wherein the first area is used to display the intracranial pressure value, the second area is used to display the intracranial temperature value, the third area is used to display the real-time intracranial pressure waveform, and the fourth area is used to display the intracranial pressure waveform and / or intracranial temperature waveform for a historical period of time; preferably, the historical period of time has more than two time lengths to choose from.

[0015] In this way, the user interface displays the intracranial pressure value, intracranial temperature value, real-time intracranial pressure waveform and historical intracranial pressure and temperature waveform through four areas, providing comprehensive intracranial status monitoring, which helps medical staff to fully understand the intracranial condition of the monitored object. The user interface also provides more than two different time lengths for flexible selection, which helps to observe the changing trend of the intracranial status of the monitored object over different time lengths.

[0016] In a possible implementation, the user interface includes a monitoring interface, and the host controls the user interface to display an input box for basic information of the monitored patient, and controls the monitoring interface to display the input basic information of the patient.

[0017] In this way, the monitor can display the input basic information of the patient, so that medical staff can intuitively view, check or understand the basic information of the patient.

[0018] In one possible implementation, the user interface includes a patient information display interface, which is used to display information of one or more patients who have previously used the intracranial pressure monitor. Before entering the patient information display interface, a password is required.

[0019] In this way, the monitor sets encryption before entering the patient information display interface to prevent irrelevant personnel from viewing or modifying private data, thereby ensuring the security of intracranial pressure monitoring data.

[0020] In one possible implementation, the patient information display interface can simultaneously display information of multiple patients, where the patient information includes the patient's name. Preferably, the patient information also includes an alarm mark, which is used to display whether the patient has had an alarm during the monitoring process and / or the corresponding matters of the alarm.

[0021] In this way, the patient information display interface can display the information of multiple patients at the same time, which allows medical staff to browse, search and compare the conditions of different patients, quickly locate the monitoring status of the patients they want to view, improve work efficiency, and by centrally displaying patient information, medical staff can more easily track the patient's care process, which is conducive to the continuity and consistency of care. The setting of alarm signs enables medical staff to quickly identify which patients have had alarm conditions, so as to give priority to emergency or serious situations.

[0022] In one possible implementation, the host displays and / or exports monitoring data of a specific patient in response to the operation of the patient information display interface. Preferably, the monitoring data includes an intracranial pressure waveform or an intracranial temperature waveform over a period of time. Further preferably, the length of the period of time has more than two time lengths to choose from.

[0023] In this way, this monitor can enable medical staff to quickly obtain key information by displaying and / or exporting monitoring data of specific patients on the patient information display interface, thereby improving the efficiency of medical decision-making, and can export intracranial pressure waveforms or intracranial temperature waveforms over a period of time, so that medical staff can conduct a more in-depth analysis of the patient's condition and optimize the monitoring plan. At the same time, it provides more than two time length options, allowing medical staff to select data from different time periods as needed, thereby enhancing the flexibility and availability of data.

[0024] In one possible implementation, the host has an alarm function, and when an alarm occurs, the user interface displays text information of the alarm item; preferably, when an alarm occurs, the host will also produce one or more of an alarm sound, flashing lights, and color changes of indicators corresponding to the alarm item on the monitoring interface; preferably, the text information of the alarm item appears on multiple different user interfaces.

[0025] In this way, the alarm function of the host can remind medical staff at critical moments, and ensure that medical staff can quickly notice and respond to alarm matters through text messages, sounds, visual stimulation and other methods, so that medical staff can take quick action to reduce the risks that may arise from untimely treatment of the monitored objects. At the same time, the text information of the alarm matters is displayed on multiple different user interfaces, which can inform the user of the cause of the alarm at any time during the entire monitoring process of the monitor, even when in different interfaces.

[0026] In a possible implementation, the alarm items include abnormal intracranial pressure and abnormal intracranial temperature, and preferably, also include at least too long implantation time, insufficient device power and device failure, and the alarm items are provided with alarm priority sorting.

[0027] In this way, the monitor can handle various alarm matters in a timely manner, remind medical staff to handle abnormalities, and ensure the correct use of the instrument.

[0028] Further features and aspects of the present disclosure will become apparent from the following detailed description of exemplary embodiments with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate exemplary embodiments, features, and aspects of the disclosure and, together with the description, serve to explain the principles of the disclosure.

[0030] Figure 1 A schematic diagram showing a zero-point calibration process of an intracranial pressure monitor provided according to an embodiment of the present disclosure is shown.

[0031] Figures 2 to 12 A schematic diagram showing an interface displayed by an intracranial pressure monitor provided according to an embodiment of the present disclosure. DETAILED DESCRIPTION

[0032] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0033] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0034] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0035] Now combined Figures 1 to 12 The intracranial pressure monitor (hereinafter referred to as monitor) provided in the embodiment of the present disclosure is schematically described.

[0036] The monitor may include a host. The host has a display screen. The display screen can be used to display a user interface. The host can be connected to a brain sensor for implantation in the skull. The brain sensor can be used to measure physiological parameters including intracranial pressure. The host can perform two or more zero-point calibrations for the same brain sensor. In this way, the monitor can provide multiple zero-point calibration opportunities for the same brain sensor to ensure the accuracy of the zero-point calibration, thereby obtaining accurate intracranial physiological parameters during the monitoring process, and is convenient for clinical operation, and can effectively solve the problem caused by the failure of the zero-point calibration of the brain sensor due to factors such as irregular calibration operations.

[0037] The host can confirm the execution of the first zero calibration procedure or the execution of the non-first zero calibration procedure in response to the user operation on the user interface. In this way, the monitor can provide the user with a confirmation operation on the calibration procedure through the user interface, making the calibration process more intuitive and easy to understand, thereby improving the user experience.

[0038] After the host is powered on, it can send out a message such as Figure 2 The first prompt T1 shown or for example Figure 3 The second prompt T2 shown, ie, controls the display screen to present the first prompt T1 or the second prompt T2 in the user interface.

[0039] The first prompt T1 can be used to remind the user that the communication connection between the brain sensor and the host is abnormal and / or remind the user of the correct communication connection method between the brain sensor and the host. When the host detects that the communication connection between the brain sensor and itself is in an abnormal state of disconnection, the first prompt T1 can be displayed in the user interface. For example Figure 2 As shown, the first prompt T1 may include the words "Attention: Please connect the brain sensor" to remind the user that the communication connection between the brain sensor and the host is abnormal, and may include Figure 2 The correct communication connection method is shown in the figure on the left. All the words and control styles shown in the interface in the figures herein are examples, which can be flexibly set in actual application, and the present disclosure does not limit this.

[0040] The second prompt T2 can be used to remind the user that the communication connection between the brain sensor and the host is successful. When the host detects that the communication connection between the brain sensor and itself is successfully connected, the second prompt T2 can be displayed in the user interface. For example Figure 3 As shown, the second prompt T2 may include the words "brain sensor identification successful" to inform the user that the brain sensor has been successfully connected to the host.

[0041] For example, the zero calibration process of a monitor can be as follows: Figure 1 shown.

[0042] When the host detects that the brain sensor is successfully connected, it automatically starts the first zero calibration confirmation procedure, that is, the control user interface appears, for example Figure 3 The first calibration control Q1 shown in the figure, and after receiving the confirmation instruction, respond to the trigger operation for the first calibration control Q1 to confirm the execution of the zero-point calibration procedure. In this way, the user interface of the monitor can display the first calibration control, so that the user can intuitively identify and confirm whether to execute the first zero-point calibration procedure, thereby improving the convenience of the calibration operation and the friendliness of the user interface.

[0043] The host can display, for example, Figure 4 The third prompt T3 shown is to inform the user that the monitor is undergoing zero-point calibration. After detecting that the zero-point calibration procedure is completed, the host can display, for example, Figure 5 The fourth prompt T4 is shown to inform the user that the monitor has completed zero point calibration.

[0044] After the first zero-point calibration is completed, the host can control the display screen to display the first zero-point calibration result, that is, the initial value of intracranial pressure. For example, the zero-point calibration result can be displayed in the monitoring interface. Since the purpose of zero-point calibration is to ensure the accuracy and reliability of the monitoring data of the monitor, the initial value of intracranial pressure should be zero. However, due to changes in the external environment, improper operation, etc., even after the first zero-point calibration, the initial value of intracranial pressure displayed by the monitor may not be zero. In this case, the user can perform another zero-point calibration through this monitor.

[0045] The user interface has a permanent calibration control, and the non-first zero-point calibration is when the host detects a trigger operation for the permanent calibration control to confirm the execution of the non-first zero-point calibration procedure. In this way, the user can perform a non-first zero-point calibration through the permanent calibration control to ensure the accuracy of the zero-point calibration, so that the monitor can obtain accurate intracranial physiological parameters during the monitoring process and facilitate clinical operation.

[0046] After the host detects that the permanent calibration control is triggered and before the non-first zero-point calibration procedure is executed, it issues a calibration operation reminder through the user interface and requires the password to be entered. In this way, by requiring the password to be entered before executing the non-first zero-point calibration procedure, the security of the calibration operation can be increased, preventing unauthorized personnel from performing calibration without authorization, protecting the security of the monitored object and data, and the calibration operation reminder can ensure that the user has met the calibration conditions before performing the calibration, such as the brain sensor is not in an implanted state, improving the calibration accuracy while ensuring the safety of the object to be detected.

[0047] The following example illustrates the process of performing a non-initial zero calibration. The user interface may display the following Figure 6The host can display the setting control Q4 in response to the trigger operation for the setting control Q4. Figure 7 The system setting prompt T6 is shown. Figure 7 As shown, the system setting prompt T6 may display a permanent calibration control Q5. The host may display a calibration component in response to a trigger operation for the permanent calibration control Q5. The calibration component may be provided with Figure 7 The calibration reminder information B2 and the first password input box X2 shown, for example, can display the calibration reminder information B2 such as "Note: It is strictly forbidden to perform this operation when the brain sensor is inside the patient" near the permanent calibration control Q5 or near the first password input box X2 or other conspicuous positions to inform the user that it is strictly forbidden to perform zero point calibration when the brain sensor is implanted in the body. In response to the input operation for the first password input box X2, the host can display the input user password in the first password input box X2 in a password-hiding manner. Figure 7 As shown, the calibration component may also display a first start control Q6 and a second cancel control Q7. The host may perform password verification in response to a trigger operation for the first start control Q6 to confirm the execution of a non-first zero-point calibration when the verification is passed (i.e., whether the entered password is the correct user password). The host may cancel the password verification in response to a trigger operation for the second cancel control Q7. Similarly to the first zero-point calibration, in the non-first zero-point calibration, the host may also display the words "The sensor is automatically calibrating..." and "Sensor calibration completed" to inform the user of the progress of the zero-point calibration. After the non-first zero-point calibration is completed, the host may display the zero-point calibration result in the same way as the first zero-point calibration. If the calibration result is still not ideal, the user may perform the non-zero-point calibration operation again as appropriate, and multiple zero-point calibrations may be performed. The calibration process is the same as the above-mentioned non-zero-point calibration, and will not be repeated herein.

[0048] Similarly to the non-first zero-point calibration, during the first zero-point calibration, a calibration operation reminder can also be issued through the user interface to ensure the safety of the monitored object. For example, a calibration reminder message such as "Caution: Do not perform this operation when the brain sensor is inside the patient" can be displayed near the first calibration control Q1 or other conspicuous locations.

[0049] In addition, if Figure 7 As shown, the user interface may also be provided with a volume setting control Q13, a brightness setting control Q14, a time setting control Q15, and a system viewing control Q16. Through these controls, the user can correspondingly set the volume of the host, the brightness of the screen, the displayed time, and the system information.

[0050] The user interface includes a monitoring interface, and the monitor can input patient information through the user interface and display it on the monitoring interface. For example, when it is confirmed that the brain sensor calibration is completed, the host controls the user interface to display the input box of the monitored patient's basic information, and controls the monitoring interface to display the input patient basic information. In this way, the monitor can display the input patient basic information, so that medical staff can intuitively view the patient information and quickly check or understand the patient's basic information.

[0051] For example, when Figure 5 After the first confirmation control Q2 indicating that the zero point calibration is completed is triggered, the host can display the result of the zero point calibration through the user interface in response to the triggering operation of the first confirmation control Q2. Figure 8 The first information prompt T5 shown. The first information prompt T5 may display multiple first input boxes X1 and a second confirmation control Q3. The host may display the determined basic information of the patient in the first information prompt T5 according to the input operation detected for the multiple first input boxes X1. The basic information of the patient may include name, gender, age, number (i.e. Figure 8 The host can switch the currently displayed first information prompt T5 to the monitoring interface in response to the trigger operation on the second confirmation control Q3, and control the monitoring interface to display the input patient basic information such as Figure 6 The patient basic information displayed in area B1 of the monitoring interface I1 is shown. The sensor number can also be Fig.12 The numbered area B5 shown is presented to the user.

[0052] like Figure 8 As shown, the first information prompt T5 can also display a first cancel control Q0. The host can switch the currently displayed first information prompt T5 to display the monitoring interface in response to the trigger operation for the first cancel control Q0. In this way, regardless of whether the input of basic information is confirmed, the host can display the monitoring interface, which is beneficial for medical staff to quickly obtain the monitoring interface in emergency scenarios. Since the input of basic information is cancelled, the monitoring interface can display the default basic information, and the default basic information can be flexibly set according to the actual situation. If the user cancels the input of the patient's basic information, the information can be supplemented and input later.

[0053] The brain sensor can collect data of physiological parameters after it is powered on, and present the physiological parameters to the host when the communication connection between itself and the host is normal, so that the host can control the display screen to display the received intracranial physiological parameters. Intracranial physiological parameters may include intracranial pressure and intracranial temperature (ICT). For example, the brain sensor may be arranged in a bougie that is convenient for the user to operate, so that when the bougie is implanted in the intracranial target area of ​​the subject to be monitored, the brain sensor can collect the physiological parameters at the intracranial target area. In some embodiments, the brain sensor may include a pressure sensor chip and a temperature sensor chip at the same time so that the brain sensor can be used to measure intracranial pressure and intracranial temperature.

[0054] After zero point calibration, the host can display intracranial physiological parameters through the monitoring interface. The monitoring interface can include multiple areas, and different areas can display different information. Figure 6 As shown, the monitoring interface I1 may include a first area A1, a second area A2, a third area A3, and a fourth area A4. The first area A1 is used to display the intracranial pressure value and related information (such as systolic pressure, diastolic pressure, upper pressure limit value, and lower pressure limit value), the second area A2 is used to display the intracranial temperature value and related information (such as upper temperature limit value and lower temperature limit value), the third area A3 is used to display the real-time intracranial pressure waveform, and the fourth area A4 is used to display the intracranial pressure waveform and / or intracranial temperature waveform for a period of history. There are more than two time lengths for selection for a period of history. In this way, the user interface displays the intracranial pressure value, intracranial temperature value, real-time intracranial pressure waveform, and historical intracranial pressure and temperature waveforms through four areas, providing comprehensive intracranial status monitoring, which helps medical staff to fully and intuitively understand the intracranial condition of the subject to be monitored, and the user interface provides more than two different time lengths for flexible selection, which helps to observe the trend of changes in the intracranial status of the subject to be monitored at different periods.

[0055] like Figure 6 As shown, the fourth area A4 may also display a first time adjustment control Q8, and the host may display a time period list including multiple optional time periods in response to the trigger operation of the first time adjustment control Q8. The host may switch the originally displayed time period to the past 3 hours when it detects that a target time period (e.g., 3 hours) is determined from multiple optional time periods. In this way, the time length selection function facilitates medical staff to focus on a specific time period and conduct a more in-depth analysis of the changing trend of intracranial physiological parameters, which helps to discover potential problems or abnormalities.

[0056] The host has an alarm function. When an alarm occurs, the user interface displays text information about the alarm and the text information about the alarm can appear on multiple different user interfaces; when an alarm occurs, the host will also sound an alarm, lights flash, and one or more of the indicators corresponding to the alarm on the monitoring interface will have abnormal colors. In this way, the alarm function of the host can remind medical staff at critical moments, and ensure that medical staff can quickly notice and respond to alarms through text messages, sounds, visual stimulation and other methods. The text information can directly and clearly display the cause of the alarm so that medical staff can take prompt action to reduce the risks that may arise due to failure to deal with the monitored object in a timely manner. At the same time, the text information of the alarm is displayed on multiple different user interfaces, and the user can be informed of the cause of the alarm at any time when the monitor is in multiple different interfaces. The following example illustrates the text information of the alarm. Fig. 9 As shown, the alarm prompt T7 can display the text information of the alarm item, such as "intracranial high pressure alarm", the text information of the alarm item can also be "intracranial high temperature alarm", "sensor failure", "low battery", etc., and the alarm items are set with alarm priority sorting, and the alarm prompt T7 displays the alarm item with the highest priority at present. Figure 7 As shown, the host can display the alarm prompt T7 while displaying the system setting prompt T6, so that the monitor can accurately remind the user to handle abnormalities anytime and anywhere. Similarly to the text information of the alarm items, the intracranial physiological parameters can also appear in multiple different user interfaces, so that the user can obtain the intracranial physiological parameters in real time during the entire process of using the monitor.

[0057] The alarm items include abnormal intracranial pressure and abnormal intracranial temperature. Preferably, they also include abnormal implantation time (too long), insufficient device power and device failure, etc. The alarm function of the host is now described. The host can perform abnormal detection. Abnormal detection is used to determine whether the monitored object has abnormalities. The abnormality type may include at least one of abnormal intracranial pressure, abnormal intracranial temperature and abnormal implantation time. Each abnormality is preset with corresponding alarm conditions, alarm priorities and alarm reminders. The host can determine in the abnormality detection that there is an abnormality at present and the current abnormality is at least one of abnormal pressure, abnormal temperature and abnormal implantation time, and issue an alarm reminder matching the current abnormality according to the alarm priority level of different abnormalities. In other words, the host can give priority to issuing an alarm reminder of an abnormality with a higher alarm priority when multiple abnormalities are detected at the same time. The alarm priority of abnormal pressure is the highest, and the alarm priorities of abnormal temperature, device failure, insufficient power and abnormal implantation time can be preset from high to low, or the priorities of several alarm conditions are the same, which can be flexibly set according to actual needs.

[0058] When it is detected that the current intracranial pressure meets the preset pressure alarm condition, the host may determine that there is a pressure abnormality to issue a pressure alarm reminder. The preset pressure alarm condition may be that the current intracranial pressure is greater than the upper pressure limit or the current intracranial pressure is less than the lower pressure limit. The pressure alarm reminder may include at least one of the following: controlling the display screen to display the pressure alarm information in the alarm prompt T7, sending the pressure alarm information to the general intensive care unit, playing the preset first sound, controlling the alarm control Q9 to display an alarm silent form to prompt the user to trigger the alarm silence, controlling the display screen to highlight the current intracranial pressure or highlighting the entire first area A1. For example, it can be Fig. 9 The words "intracranial hypertension alarm" are displayed in the alarm prompt T7, and a color reminder will appear in the first area A1 for displaying the intracranial pressure value in the monitoring interface, for example Fig. 9 The first area A1 is highlighted in red, reminding the user that the subject to be monitored has abnormal intracranial pressure, so that the user can deal with the abnormal situation in time. It should be noted that the sound of various alarm reminders provided in the embodiment of the present disclosure can be flexibly set in type and duration according to actual conditions.

[0059] The alarm for abnormal intracranial temperature is similar to the alarm for abnormal intracranial pressure, that is, the temperature alarm reminder is the same as the pressure alarm reminder. When the host detects abnormal temperature, it will control the display screen to highlight the area related to the intracranial temperature. Considering the alarm priority, the host may not necessarily control the display screen to display the abnormal temperature alarm information in the text information of the alarm prompt T7. For example, Fig. 9 As shown, at this time, the host detects temperature abnormalities and pressure abnormalities, controls the display screen to display pressure alarm information in the alarm prompt T7, controls the first area A1 to be in a red highlighted state, and controls the second area A2 to be in an orange highlighted state. In this way, different display methods are used for different types of abnormalities, which helps users to quickly distinguish different abnormalities.

[0060] The host can record the implantation time of the brain sensor based on the bougie serial number and display the implantation time in the monitoring interface, e.g. Fig. 9 The implantation prompt B3 in the monitoring interface I1 shown shows that the implantation time is 5 hours and 51 minutes. The host can issue an implantation alarm reminder when it detects that the current implantation time meets the preset implantation alarm conditions. The implantation alarm reminder may at least include controlling the display screen to highlight the implantation time in the monitoring interface. For example, the preset implantation alarm threshold is 5 days of implantation. When the implantation time is within 5 days, it will be displayed in blue. After the implantation time exceeds 5 days, the blue will turn red. Such color distinction can enhance the visual reminder effect. This monitor not only takes into account pressure abnormalities and temperature abnormalities, but also introduces the implantation time of the brain sensor as one of the alarm types, which helps to promptly discover and deal with monitoring errors or infection risks that may be caused by excessive sensor implantation time.

[0061] like Fig.12 As shown, the monitoring interface I1 may also display a power control Q29. The host may display the remaining power of the monitor in response to a trigger operation on the power control Q29. The host may issue a low-power device reminder in response to the remaining power falling to a preset value. In addition, the host may also issue a fault reminder in response to a device failure. The relevant settings of the low-power device reminder and fault reminder can refer to the description of the alarm function above, which will not be repeated here.

[0062] The monitor also provides an alarm silencing function for target alarm reminders. The monitoring interface I1 can also display an alarm control Q9. When the monitor host detects that the intracranial physiological parameters are normal, it controls the alarm control Q9 to display an alarm state, such as Figure 6 When abnormal intracranial physiological parameters are detected, the host can control the alarm control Q9 to display as Fig. 9 The alarm silent mode is shown, which can prompt the user to trigger the alarm silent mode through the alarm control Q9 in the alarm silent mode. Alarm silent mode may include stopping the sound playback and / or stopping the color flashing in the target alarm reminder. In this way, when the user triggers the alarm control Q9 in the alarm silent mode, the monitor can respond immediately, avoid unnecessary noise interference by stopping the sound playback, and avoid unnecessary visual interference by stopping the alarm color flashing. Normally, the host will not allow the next operation and interface switching until it detects that it has entered the alarm silent state. In this way, when medical staff are executing the treatment plan, the alarm silent state may not interfere with the operation of medical staff.

[0063] The host can automatically switch to the alarm state when it detects that the duration of the alarm silent state meets the preset duration, and control the alarm control Q9 to display in the alarm form, and restore the alarm for the currently detected abnormal matters. For example, after the host issues a temperature alarm reminder, it detects that the alarm control Q9 in the alarm silent form is triggered, then stops playing the second sound and records the duration of the alarm silent state. If it is detected that the duration meets certain conditions such as 2 minutes, it automatically switches from the alarm silent state to the alarm state, and controls the form of the alarm control Q9 to switch to the alarm form. The host continues to monitor the current intracranial physiological parameters. If it is determined that there is no abnormality in the brain sensor at this time based on the latest monitored intracranial temperature compared with the temperature of the alarm condition, the temperature alarm reminder will not be issued. The intracranial pressure and implantation duration are similar, and will not be repeated. It should be noted that although the host can detect that the alarm control Q9 in the alarm silent form is triggered and enters the alarm silent state, during the entire alarm silent process, pressure abnormalities, temperature abnormalities, and implantation duration abnormalities can still be detected, so as to be recorded in the historical information. In addition, if the host detects an intracranial pressure abnormality with a higher alarm priority when the alarm is silent, it can break the silence and issue an intracranial pressure alarm. In this way, the monitor ensures that even if the user enables the alarm silent function, it can still continue to monitor the patient's physiological condition, so as to issue an alarm reminder in time when a higher priority abnormality occurs, thereby improving the continuity and safety of monitoring.

[0064] In addition, the alarm control Q9 also has an alarm off mode. The host can turn off the target alarm reminder when it detects that the alarm mode of the alarm control Q9 is switched to the alarm off mode. The alarm mode, alarm silent mode, and alarm off mode of the alarm control Q9 can correspond to different styles, so that the user can understand whether the current alarm reminder is alarm, silent, or off through the style of the alarm control Q9. The style of the alarm control Q9 can be flexibly set, and the embodiments of the present disclosure do not limit this.

[0065] The monitor can set the alarm threshold. Fig.10 The host can display an alarm setting prompt in response to a trigger operation on the alarm setting control Q10. Fig.10 As shown, the alarm setting prompt T8 can display the currently set pressure upper limit value (for example Fig.10 The high pressure shown is 20 mmHg) and the lower pressure limit, Fig.10 The first setting area C1 does not display the pressure unit, but can be adjusted according to actual needs, and the embodiment of the present disclosure does not limit this; the alarm setting prompt T8 can display the currently set temperature upper limit value (for example, Fig.10The high temperature shown is 38.5°C) and the lower temperature limit. The temperature unit is the same as the pressure unit and will not be repeated here. When the host detects a pressure setting operation for the upper pressure limit and / or the lower pressure limit, the upper pressure limit and / or the lower pressure limit displayed in the alarm setting prompt T8 can be updated according to the pressure setting operation. Similar to the pressure setting operation, the monitor can also set the detection of temperature setting operations. The pressure setting operation, temperature setting operation and implant setting operation can be implemented in the form of input boxes, sliding bars, options, etc., and can be flexibly set according to actual conditions. The embodiments of the present disclosure do not limit this.

[0066] Alarm setting prompt T8 can also display Fig.10 The host can adjust the required abnormality detection when the trigger operation for the alarm switch control Q11 is detected. Adjustment means turning abnormality detection on or off. Multiple alarm switch controls can be set, so that each alarm switch control can correspond to a different abnormality type. Or, Fig.10 As shown, only one alarm switch control Q11 can be set to control the opening and closing of all abnormalities at the same time. For example, when the host detects that the alarm switch control Q11 is adjusted to closed, it enters the alarm closed state. At the same time, the alarm control Q9 at the lower right corner of the interface is displayed as the corresponding alarm closed state. Before switching to the alarm closed state, you also need to enter a password, which is displayed as follows Fig.11 The second information prompt T10 is similar to the prompt page and input box, so as to avoid abnormal use of the monitor due to misoperation.

[0067] like Fig.10 As shown, the alarm setting prompt T8 may also display an alarm recovery control Q12. When the host detects a trigger operation for the alarm recovery control Q12, the host may restore the currently set alarm conditions of each abnormality to the default alarm conditions. The default alarm conditions may include, but are not limited to, information related to pressure abnormalities (such as an upper pressure limit, a lower pressure limit, pressure alarm information, a first sound, information related to temperature, and information related to implanted alarms).

[0068] The monitor also provides patient information related functions, such as viewing, editing, and exporting. The user interface includes a patient information display interface, which is used to display the information of one or more patients who have used the intracranial pressure monitor. Before entering the patient information display interface, a password is required. In this way, the monitor sets encryption before entering the patient information display interface to prevent unrelated personnel from viewing or modifying private data, thereby ensuring the security of intracranial pressure monitoring data.

[0069] The patient information display interface can display the information of multiple patients at the same time. The patient information includes the patient's name. Preferably, the patient information also includes an alarm mark, which is used to display whether the patient has an alarm during the monitoring process and / or the corresponding matters of the alarm. In this way, the patient information display interface can display the information of multiple patients at the same time, which allows medical staff to quickly browse, search and compare the conditions of different patients, improve work efficiency, and by centrally displaying patient information, medical staff can more easily track the patient's care process, which is conducive to the continuity and consistency of care. The setting of the alarm mark enables medical staff to quickly identify which patients have had alarms, so as to give priority to emergency or serious situations.

[0070] The host can display and / or export the monitoring data of a specific patient in response to the operation of the patient information display interface. Preferably, the monitoring data includes an intracranial pressure waveform or an intracranial temperature waveform for a period of time. Further preferably, the length of a period of time has more than two time lengths to choose from. In this way, the monitor can enable medical staff to quickly obtain key information by displaying and exporting the monitoring data of a specific patient on the patient information display interface, thereby improving the efficiency of medical decision-making, and can export the intracranial pressure waveform or intracranial temperature waveform for a period of time, so that medical staff can conduct a more in-depth analysis of the patient's condition and optimize the monitoring plan. At the same time, more than two time length options are provided, so that medical staff can select data from different time periods as needed, thereby enhancing the flexibility and availability of data.

[0071] The following is an example of the patient information related functions of this monitor.

[0072] The user interface can also display Fig.11 The host may display a second information prompt in response to a trigger operation on the information control Q20. Fig.11 As shown, the second information prompt T10 displays a second password input box X3. In response to the input operation on the second password input box X3, the host can display the input user password in the second password input box X3 in a password-hiding manner. Fig.11 As shown, the second information prompt T10 may also display a second start control Q21 and a third cancel control Q22. The host may perform password verification in response to the trigger operation for the second start control Q21, so that the host may control the display screen to display the waveform and the patient list after the password verification is passed. In this way, the function of viewing user information is encrypted, which helps to ensure information security. In addition, when viewing user information, the host may also display the words "Wrong password input" in the alarm prompt T7 in response to the failure of password verification to remind the user to enter the correct password. The host may cancel the password verification in response to the trigger operation for the third cancel control Q22.

[0073] The host can be Fig.12 The waveform graph and the second time adjustment control Q23 are shown in the first sub-area D1. The waveform graph can be used to indicate the historical trend of the intracranial physiological parameters of the default object. The host can update the time period of the historical trend displayed in the waveform graph in response to the time period setting operation for the time period corresponding to the historical trend in the waveform graph. The time period setting operation can be determined based on the trigger operation of the second time adjustment control Q23. Fig.12 The triggering operation of the second time adjustment control Q23 shown is similar to Figure 6 The triggering operation of the first time adjustment control Q8 is shown in detail in the previous text and will not be repeated here.

[0074] The host can be Fig.12 The second sub-area D2 shown displays a patient list, which displays historical information, export controls, delete controls, and edit controls of at least one patient. Each historical information includes the corresponding patient's name, gender, age, number, sensor number, implantation duration, and alarm mark.

[0075] like Fig.12 As shown, a plurality of optional items Q24 are displayed in the patient list. Each optional item Q24 corresponds to the historical information of a different patient. When the host detects a confirmation operation of selecting a second target patient from at least one patient, the historical trend of the current patient displayed in the waveform chart can be updated to the historical trend of the second target patient. The confirmation operation can be determined by a trigger operation of the optional item Q24. For example, when the host detects a trigger operation for a certain optional item Q24, the patient corresponding to the optional item Q24 can be used as the second target patient, thereby controlling the display screen to display the historical trend of the patient in the waveform chart.

[0076] like Fig.12 As shown, an export control Q25 may also be displayed in the second sub-area D2. The host may export the target information of the selected second target patient to the target location in response to the trigger operation for the export control Q25. The number of the second target patients may be one or more, and the target information includes at least one of the following: historical information, historical trends of intracranial physiological parameters, and alarm event information. The alarm event information may include at least the time when monitoring starts, the type of alarm, the duration of the alarm, the intracranial physiological parameters at the time of the alarm, and the time when the alarm occurs.

[0077] like Fig.12 As shown, a delete control Q26 may also be displayed in the second sub-area D2. In response to a trigger operation on the delete control Q26, the host may delete the historical information and historical trends of the intracranial physiological parameters of the selected second target patient.

[0078] like Fig.12As shown, an editing control Q27 may also be displayed in the second sub-area D2. In response to the triggering operation of the editing control Q27, the host may edit the basic information of the selected second target patient according to the editing operation input by the user.

[0079] like Fig.12 As shown, the patient list also displays the alarm identification Q28 of each patient. When the host detects the confirmation operation of selecting the target identification from the alarm identification Q28 of at least one patient, it can display the alarm event information of the patient corresponding to the target identification. The confirmation operation can be a trigger operation for the alarm identification Q28. For example, the host can display the alarm event information of the patient in response to the trigger operation of the alarm identification Q28 corresponding to a certain patient. The alarm event information includes at least one of the following: current abnormality, alarm duration, intracranial physiological parameters at the time of alarm, and time of abnormal occurrence. In addition, different alarm types can be distinguished and displayed by alarm identifications Q28 of different colors. For example, the red alarm identification Q28 indicates abnormal pressure or abnormal implantation duration, and the yellow alarm identification Q28 indicates abnormal temperature. In this way, different styles of alarm identifications Q28 can be used to facilitate users to understand the monitoring information of different patients. In order to quickly focus on the most urgent situation of the patient, the host can only display the alarm identification Q28 of the highest priority abnormality.
