Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical monitoring system, in particular to a medical monitoring system, a method for displaying monitoring data and a monitoring display device. BACKGROUND

[0002] Patient monitoring systems are widely used in hospitals, for example in intensive care units (ICU), to monitor the physiological state of patients. A common patient monitoring system usually includes a bedside monitor with one or more sensors placed on the patient to sense parameter data of ECG, blood pressure, blood oxygen, blood sugar and body temperature, etc., which can be displayed on a video display or stored for subsequent analysis.

[0003] When medical staff reviews the historical parameter data of a patient using a monitor, they generally need to browse the parameter changes of the patient in a past period of time to find some abnormal or key change time points for detailed viewing. Currently, the monitor usually presents the historical data of the patient in a window, and the medical staff can adjust the content of the patient's historical data displayed in the window by adjusting the sampling interval / window time period of the patient's historical data displayed in the window. The disadvantage of this method is that when the medical staff uses a small data sampling interval / a short window time to view, they cannot understand the parameter data change of the patient outside the display window time. When the medical staff uses a large data sampling interval / a long window time to view, they can understand the parameter data change of the patient in a long period of time, but the information of the abnormal or key change time points is not displayed in detail, which causes the medical staff to need to frequently switch between different data sampling intervals / window times, and the browsing operation is very inconvenient.

[0051] The contact / motion module 136, together with the touchscreen display controller 122, detects contact with the touchscreen 126. The contact / motion module 136 includes various software components for performing various operations associated with contact detection on the touchscreen 126, such as determining whether a contact has occurred, determining whether the contact has moved, tracking movement on the touchscreen 126, and determining whether the contact has been interrupted (i.e., whether the contact has stopped). Determining the movement of the contact point may include determining the rate (amplitude), velocity (amplitude and direction), and / or acceleration (including amplitude and / or direction) of the contact point.

Further details related to the user graphical interface will be described below.

[0054] The above Figure 1 This merely refers to a structural block diagram of a medical monitoring system 100. System 100 is just one example of a medical monitoring device.

[0056] The system 100 can have a plurality of graphical user interface states. A graphical user interface state is a state in which the system 100 responds to user input in a predetermined manner. In some embodiments, the plurality of graphical user interface states include a display interface for current monitoring time parameter data and historical time interval parameter data. Herein, a time interval refers to a time period.

[0057] Figure 2 A graphical user interface for some embodiments of the present application. Figure 2 The graphical user interface 200 shown in FIG. 1 presents current monitoring time and historical monitoring time interval parameter data information. In some embodiments, the graphical user interface 200 includes a first region 202, a second region 204, a third region 206, and a fourth region 208.

[0058] In some embodiments, the first area 202 includes a patient information area 210, such as the number of the ICU (Intensive Care Unit) where the patient is located, and the like, an important physiological parameter abnormality marker area 212, and a current monitoring time area 214. In some of the embodiments, the important physiological parameter abnormality marker area 212 further includes a button for printing a 12-lead ECG and important physiological parameter abnormality markers, which include but are not limited to ECG high frequency noise and Art Sys Too High. The current monitoring time area 214 includes but is not limited to an indication of whether the sound is on, the current monitoring time, the network connection status, and the power level of the system 100, and the like.

[0059] In some embodiments, the second area 204 is disposed in the middle of the graphical user interface. The second area 204 includes parameter data of the current monitoring time. The parameter data is displayed in the form of waveforms and numerical values. In some of the embodiments, the upper left portion of the second area 204 displays the parameter data in the form of waveforms, and the upper right portion and the bottom of the second area 204 display the parameter data in the form of data and percentages. The arrangement of the waveforms and the numerical values can also have other forms, which are not limited to the description of the embodiments.

[0060] In some embodiments, the third area 206 includes but is not limited to being displayed in a layer on the left front portion of the second area 204. The third area 206 includes parameter data in a historical monitoring time interval. The third area 206 will be described in detail in combination with Figures 3 to 8 In some embodiments, the fourth area 208 further includes a menu area. The menu area further includes at least one menu icon or button 216. The at least one menu icon or button 216 is used to set the display form of the graphical user interface, such as a display setup button, a privacy mode button, a standby mode button, an audio pause button, a volume setup button, and the like.

[0061] The following will take Figures 3 to 8 as an example to illustrate the case where the third area 206 displayed by the graphical user interface 200 displays parameter data in a historical monitoring time interval.

[0062] In some embodiments, as Figure 3As shown, the third region 206 includes a title region 208, a menu region 212, a waveform display region 218, a historical monitoring time interval region 220, a monitoring time selection region 222, and a configuration menu region 224. The title region 208 is disposed at the top of the graphical user interface 300, the menu region 306 and the current monitoring time region 310 are disposed in sequence at the lower portion of the menu region 306, and occupy the upper region in the graphical user interface 300. The waveform / data display region 312 is disposed at the middle portion of the third region 206, the historical monitoring time interval region 220 and the monitoring time selection region 222 are disposed in sequence at the lower portion of the waveform display region 218, and the configuration menu region 224 is disposed at the bottom of the third region 206.

[0063] In some embodiments, the title region 208 further includes at least one shortcut operation icon 210, such as a printer, a close icon, etc. The menu region 212 includes at least one parameter data display mode icon or button 214, which further includes a List Trend button, a Graphic Trend button, an Events button, a Full Disclosure button, an OxyCRG button, a 12-lead ECG button, and an ST segment button. In this embodiment, the parameter data in the historical monitoring time interval is displayed in the form of a Full Disclosure. In some embodiments, in this embodiment, the waveform display region 218 displays the parameter data in the historical monitoring time interval in the form of a waveform in the Full Disclosure mode.

[0064] In some embodiments, the historical monitoring time interval region 220 includes a main timeline 226 (or time axis, referred to as a global timeline, global time axis, etc.), a main viewing marker 228 disposed on the main timeline 226, and an abnormality marker 230 for indicating an abnormal event. In one embodiment, the main timeline 226 (monitoring time line) corresponds to the entire monitoring time period of a single patient up to the current time, and the abnormal event is an abnormal event generated according to all monitoring parameters that occurs in the monitoring time period.

[0065] In some embodiments, the main timeline 226 indicates the entire length of time from the start of monitoring to the current monitoring time of the patient. In some embodiments, the main timeline 226 can be displayed as a line or a long bar. For example Figure 3 a horizontal long bar. In addition, when the display controller 122 does not receive an input instruction, the main timeline 226 will be hidden.

[0066] In some embodiments, when the display controller 122 receives an input command from a user (medical staff) via the main timeline 226, it positions the main viewing marker 228 to the anomaly identifier 230 corresponding to the anomaly event closest to the input time point. The input time point can be any moment or time segment within the historical monitoring time interval on the main timeline 226. When the user (medical staff) views parameter data on the main timeline 226, the waveform display area 218 displays the parameter data corresponding to the anomaly event closest to the input time point. In this embodiment, the parameter data within the time segment of the anomaly event corresponding to the anomaly identifier 230 is shown in 236.

[0067] In some embodiments, the main viewing marker 230 is overlaid on the main timeline 226 and can be moved along the main timeline 226. In this embodiment, the user (guardian) can use a finger placed on the touch display screen 126 or other input devices 128, such as, but not limited to, a mouse, gamepad, keyboard, joystick, click wheel, etc., to control the main viewing marker 228 to select the monitoring time corresponding to the main viewing marker 228.

[0068] In some embodiments, the main viewing marker 228 is displayed as a slider / slider, and the width of the main viewing marker 228 is greater than the width of the horizontal bar used to represent the main timeline 316. This makes it easier for medical staff to select the monitoring time via the touch display screen 126. The parameter data of the monitoring time segment corresponding to the main viewing marker 228 can be viewed by moving the main viewing marker 228. In this embodiment, the downward arrow of the main viewing marker 228 indicates the historical monitoring time point corresponding to the main viewing marker 228, such as 05-07, 04:50. Simultaneously, the time corresponding to the main viewing marker 228 is also displayed synchronously in section 216. The parameter data of the time segment corresponding to the monitoring time corresponding to the main viewing marker 228 corresponds to the time window 234 section of the waveform display area 218.

[0069] Time window 234 represents the position and / or proportion of the time segment corresponding to the monitoring time corresponding to the main viewing mark 228 within the historical monitoring time interval. As the main viewing mark 228 moves, time window 234 also moves accordingly.

[0070] In some embodiments, the length of the slider / slider identifying the main viewing mark 234 can be extended or retracted, for example, by the relative horizontal movement of two contact points detected on the touch display screen 126. Extending the slider / slider can lengthen the time segment in which the monitoring moment corresponding to the main viewing mark 234 is located. Similarly, shortening the slider / slider can shorten the time segment in which the monitoring moment corresponding to the main viewing mark 234 is located.

[0071] In some embodiments, the main timeline 226 includes an anomaly identifier 230 displayed on the main timeline 226 to indicate an abnormal event when an anomaly occurs. These abnormal events include physiological parameter alarms, events manually marked by healthcare personnel when an anomaly is detected, and technical alarm events related to patient parameter measurements, etc.

[0072] In some embodiments, the anomaly identifier 230 is displayed as a light bar of different colors and / or shapes according to the different attributes of the anomaly event described above. For example, different attributes of the anomaly identifier 230 can be displayed as different colors, and the duration of the anomaly event with different attributes can be displayed as different shapes. In this embodiment, the length of the light bar is set according to the duration of the anomaly event. For example, if the anomaly event lasts for a long time, the width of the vertical light bar is larger.
