The display 340 can be liquid-crystal display (LCD), light-emitting diode (LED) display, vacuum fluorescent display (VFD), plasma display panel (PDP), organic light-emitting diode (OLED), or field-emission display (FED).
The portable electronic device 100 can obtain a physiological signal of the user through the sensor 140, and can transmit the physiological signal or the position information to the terminal device 200 through the transceiver 130. In an embodiment, the sensor 140 may include a photoelectric sensor, and the physiological signal may include a photoplethysmography (PPG) signal.
After receiving the physiological signal, the processor 210 of the terminal device 200 can extract a feature value from the physiological signal. In an embodiment, the processor 210 can calculate the user's heart rate according to the PPG signal, wherein the heart rate is, for example, the user's average heart rate during a preset period of time (for example: 32 seconds). In an embodiment, the processor 210 can calculate a peak-to-peak interval (PPI) in the PPG signal, where the peak-to-peak interval is, for example, the average peak-to-peak interval of the user during a predetermined period of time (such as, 32 seconds).
After obtaining the feature value of the physiological signal (for example: heart rate or peak-to-peak interval), the processor 210 can determine whether an abnormal event related to the user's cardiovascular system occurs according to the feature value. In an embodiment, the processor 210 may determine that an abnormal event occurs in response to the user's heart rate being greater than a first threshold (for example: 170 bpm) or less than a second threshold (for example: 40 bpm, wherein the second threshold is less than the first threshold). In an embodiment, the processor 210 may determine that an abnormal event occurs in response to the user's peak-to-peak interval being less than a third threshold.
If the processor 210 determines that an abnormal event occurs, the processor 210 may transmit a first feedback information corresponding to the physiological signal to the server 300, the first feedback information may include information such as the physiological signal, the feature value of the physiological signal (such as heart rate or peak-to-peak interval), or the position information measured by the positioning device 150. If the processor 210 determines that no abnormal event has occurred, the processor 210 may not transmit the first feedback information to the server 300, so as to save power or communication resources consumed by the terminal device 200.
After receiving the first feedback information, the processor 310 of the server 300 can generate and output the alarm message according to the first feedback information, wherein the alarm message can be related to the physiological signal, the feature value of the physiological signal (such as heart rate or peak-to-peak interval), or the position information and other information. The processor 310 can, for example, transmit the alarm message to relevant personnel through instant messaging software, web browser, email, or short message service (SMS), etc.
In an embodiment, before the server 300 outputs the alarm message, the server 300 can display a graphical user interface through the display 340 for medical personnel to watch, wherein the graphical user interface may include the physiological signal, the feature value of the physiological signal (such as heart rate or peak-to-peak interval), or the position information and other information. The medical personnel can determine whether the abnormal event occurred this time is a misjudgment according to the physiological signal or the feature value. If the medical personnel determines that the abnormal event is not a misjudgment, the medical personnel can operate the server 300. The server 300 can receive user operations from the medical personnel, and output the alarm message according to the user operations. That is to say, the present invention provides a rejudgment mechanism for the medical personnel on abnormal events, so as to avoid the waste of medical information or rescue information caused by misjudgment of abnormal events.
In an embodiment, the processor 210 can transmit a second feedback information corresponding to the physiological signal to the server 300 according to a preset period. Compared with the first feedback information which is transmitted to the server 300 in real time when an abnormal event occurs, the second feedback information can contain long-term information. For example, the processor 210 can transmit the second feedback information related to the user's physiological signals throughout the day to the server 300 at a preset period of one day.
The processor 310 of the server 300 can generate and output a physiological state report of the user according to the second feedback information. For example, the processor 310 can display the physiological state report through the display 340 for medical personnel or ambulance personnel to watch. The physiological state report may include but not limited to a recording period of the physiological signal, a proportion of available physiological signals in the recording period, a proportion of abnormal atrial fibrillation, a frequency of occurrence of atrial fibrillation, a frequency of high heart rate, a frequency of low heart rate, a distribution of the abnormal events, and a waveform diagram of the physiological signal related to the abnormal event and other information, wherein the aforementioned information can be transmitted from the terminal device 200 to the server 300 through the second feedback information.
In summary, the portable electronic device of the present invention can be worn by the subject to measure the physiological signal of the subject in real time, and transmit the physiological signal to the terminal device with computing power. The terminal device can monitor the physiological signal to determine whether the subject has abnormal events associated with cardiovascular disease. The terminal device can transmit the relevant feedback information of the subject to the medical personnel or ambulance personnel when an abnormal event occurs, so as to report the physiological state and location information of the subject. After the medical personnel analyze the feedback information and determine that the report of the abnormal event is not a false alarm, the server can output the alarm message to the relevant personnel according to the user operation of the medical personnel. The present invention can not only monitor the physiological condition of the subject at any time, but also transmit the physiological signal of the subject to remote medical personnel for analysis. In this way, the probability of false alarms can be significantly reduced. Compared with the emergency equipment set in a fixed position (for example: emergency bell), the present invention can automatically report abnormal events through the portable electronic device that is easy to wear and small in size and the terminal device that does not require additional cost, so as to prevent the subject from losing consciousness and being unable to actively seek assistance.
