Title: Medical monitoring system, method of displaying monitoring data, and monitoring data display device

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of PCT Application No. PCT/CN2015/091665, filed Oct. 10, 2015, for MEDICAL INTENSIVE CARE SYSTEM, METHOD OF DISPLAYING INTENSIVE CARE DATA, AND INTENSIVE CARE DATA DISPLAY DEVICE, which is incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to the field of medical monitoring systems, and in particular to a medical monitoring system, a method of displaying monitoring data, and a monitoring data display device. 
     BACKGROUND ART 
     Patient monitoring systems are commonly used, for example, in intensive care units (ICUs) of hospitals to monitor physiological states of patients. A common patient monitoring system is a bedside monitoring device having one or more sensors disposed on the patient to sense parameter data, such ECG, blood pressure, blood oxygen, blood glucose, and temperature. The parameter data can be displayed on a video display or stored for subsequent analysis. 
     When health care personnel review historical parameter data of the patient with a monitoring device, they generally need to browse parameter change conditions of the patient over a past period of time so as to find anomalous or key change time points for inspection. Conventional monitoring devices generally present historical data of the patient with one window, and the health care personnel adjust the contents of the historical data of the patient displayed in the window by adjusting a sampling interval or window time interval of the historical data of the patient displayed in the window. A defect of this method is that the health care personnel cannot observe parameter data change conditions of the patient outside the selected time interval of the display window when inspecting with a smaller data sampling interval, e.g., shorter window time interval. Likewise, when inspecting a greater data sampling interval, e.g., longer window time interval, although the health care personnel can observe the parameter data change conditions over a wider time range, information about these anomalous or key change time points is not displayed in sufficient detail, which causes the health care personnel to frequently switch between different data sampling intervals or window time intervals, making browsing operations inconvenient. 
     SUMMARY 
     To solve the aforementioned problems, a medical monitoring system, a method of displaying monitoring data, and a monitoring data display device are provided. In one embodiment, a medical monitoring system may include: a memory; one or more signal sampling devices to detect parameter data corresponding to at least one physiological parameter; a display to display the parameter data obtained by the one or more signal sampling devices; and a processor to obtain, according to the parameter data, instructions of anomalous events with a plurality of different attributes, and transmit the instructions of the anomalous events to the display; wherein one or more anomalies identifiers corresponding to the anomalous events are displayed on a monitoring timeline according to the attributes of the anomalous events. 
     In one embodiment, a method of displaying monitoring data may include: obtaining parameter data of at least one physiological parameter; obtaining, according to the parameter data, anomalous events with a plurality of different attributes; and displaying, according to the attributes of the anomalous events, one or more anomalies identifiers corresponding to the anomalous events in a monitoring timeline. 
     In one embodiment, a display device may include: a memory to store at least one physiological parameter and parameter data corresponding to the at least one physiological parameter; a display to display the parameter data; and a processor to obtain, according to the parameter data, instructions of anomalous events with a plurality of different attributes, and transmit the instructions of the anomalous events to the display; wherein one or more anomalies identifiers corresponding to the anomalous events are displayed in the entire monitoring time interval of a timeline according to the attributes of the anomalous events. 
     The medical monitoring system, method of displaying monitoring data, and monitoring data display device enhance convenience for users, such as health care personnel, to inspect parameter data of a patient in a historical monitoring time interval, greatly improving the user experience.

The menu region further includes at least one menu icon or button  216 . The display form of the GUI can be via at least one menu icon or button  216 , for example, a display setup (Display setup) button, a privacy mode (Privacy Mode) button, a standby mode (Standby) button, an audio pause (Audio Pause) button and a volume setup (Volume Setup) button. 
     The parameter data in the historical monitoring time interval that are displayed in the third region  206  of the GUI  200  are illustrated by referring to  FIGS. 3 to 8 . 
     In some embodiments, as shown in  FIG. 3 , 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 .

In this embodiment, the waveform display region  218  displays the parameter data in the historical monitoring time interval in the form of waveforms in a holographic waveform (Full Disclosure) mode. 
     In some embodiments, the historical monitoring time interval region  220  includes a main timeline  226  (or a time axis, an overall timeline, or an overall time axis, the same below), a main inspecting label  228  provided on the main timeline  226 , and one or more anomalies identifiers  230  for representing anomalous events. In an embodiment, the main timeline  226  (a monitoring timeline) corresponds to an entire monitoring time period of a single patient up to current time, and the anomalous events are anomalous events occurring according to all monitoring parameters that happen within the monitoring time period. 
     In some embodiments, the main timeline  226  indicates the whole time length from the starting of the monitoring of a patient to the current monitoring time. In some embodiments, the main timeline  226  can be displayed as a linear or elongated shape, for example, a horizontal long strip as shown in  FIG. 3 . In addition, when the display controller  122  receives no input instruction, the main timeline  226  will be hidden in one embodiment. 
     In some embodiments, when the display controller  122  receives an input instruction from users (health care personnel) through the main timeline  226 , the main inspecting label  228  is positioned to a nearest anomalies identifier  230 . In other words, a user input instruction at a particular point on the monitoring timeline may be detected, after which an anomalous event closest in time to the particular point is selected and the display of historical parameter data may be centered on the selected anomalous event. This is done in recognition that health care professionals may be primarily concerned about viewing details of anomalous events and the closest ones in time to a particular time of interest. The input time point can be any moment or time clip in the historical monitoring time interval of the main timeline  226 . When the users (health care personnel) inspect parameter data on the main timeline  226 , the waveform display region  218  displays parameter data corresponding to the main inspecting label  228 . 
     In some embodiments, the main inspecting label  230  is sleeved on the main timeline  226  and can move along the main timeline  226 . In this embodiment, a user (monitoring personnel) may utilize his or her finger on the touch display screen  126  or the other input apparatus  128 , for example but not limited to a mouse, a handle, a keyboard, a joystick, a click wheel, etc. to control the main inspecting label  228 , so as to selectively inspect monitoring moments corresponding to the main inspecting label  228 . 
     In some embodiments, the main inspecting label  228  is displayed as a slide bar/slide block, and the width of the main inspecting label  228  is greater than that of the horizontal long strip for representing a main timeline  226 . In this way, it is convenient for the health care personnel to select monitoring time through the touch display screen  126 . The parameter data of the monitoring time clip corresponding to the main inspecting label  228  are inspected by moving the main inspecting label  228 . In this embodiment, the downward arrow of the main inspecting label  228  indicates the historical monitoring time point corresponding to the main inspecting label  228 , for example, 05-07, 04:50. In one embodiment, the downward arrow of the inspecting label may represent a middle monitoring time point of the inspecting period. At the same time, the time corresponding to the main inspecting label  228  is also synchronously displayed in the part  216 . The parameter data in the time clip of the monitoring moment corresponding to the main inspecting label  228  correspond to a time window  234  in the waveform display region  218 . 
     The time window  234  represents the position and/or proportion of the time clip of the monitoring moment corresponding to the main inspecting label  228  in the historical monitoring time interval. With the movement of the main inspecting label  228 , the time frame  234  also moves accordingly. 
     In some embodiments, the slide bar/slide block identifying the main inspecting label  228  can be lengthened or shortened, for example, the slide bar/slide block can be lengthened or shortened by the relative movement of two contact points detected on the touch display screen  126  in a horizontal direction. The length of the time clip corresponding to the monitoring moment of the main inspecting label  228  can be expanded by extending the slide bar/slide block. Likewise, the length of the time clip corresponding to the monitoring moment of the main inspecting label  228  can be shortened by shortening the slide bar/slide block. 
     In some embodiments, the main timeline  226  includes the anomalies identifier  230  for representing the anomalous events, displayed on the main timeline  226  when an anomaly occurs. The anomalous events include a physiological parameter warning, a manually labeled event when health care personnel find an anomaly, and a technical warning event relevant to patient parameter measurement, etc.
