Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the priority of Korean Patent Application No. 10-2024-0158107 filed on November 8, 2024, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND Field The present disclosure relates to an intelligent defibrillator operating system and method through motion detection, and more particularly, to an intelligent defibrillator operating system and method through motion detection that is capable of controlling the operation of an automated external defibrillator (AED) based on the tilt, acceleration, and maintenance time of tilt and acceleration changes of the AED. Description of the Related Art The conventional automated external defibrillator (AED) 10 includes a power supply unit 11, a display unit 12, a voice output unit 13, electrodes 14, a defibrillation pulse unit 15, and a control unit 16, as illustrated in FIG. 1. The defibrillation pulse unit 15 is connected to the electrodes 14. The electrodes 14 are attached by the user to a part of the patient's body (preferably, the cardiac side), receive the patient's electrocardiogram (ECG) signals, and transmit them to the defibrillation pulse unit 15. The defibrillation pulse unit 15 transmits the ECG signals to the control unit 16. In addition, when an abnormal pattern (e.g., dangerous cardiac rhythms such as ventricular fibrillation, pulseless ventricular tachycardia, asystole, bradycardia, tachycardia, and others) in the ECG signals is analyzed during the process of analyzing the patient's ECG signals, the control unit 16 controls the display unit 12 or the voice output unit 13 to generate a warning alert and provide the patient's status information to the user. Further, the control unit 16 controls the defibrillation pulse unit 15 to generate a defibrillation pulse for treating the patient in whom an abnormal pattern in the ECG signals is detected. Such a conventional automated external defibrillator 10 is typically stored in a designated location. When an emergency situation occurs, and the user carries the automated external defibrillator 10 from the designated location to the patient, then presses a button or opens a cover (lid) by hand, the power supply unit 11 supplies power, thereby converting the automated external defibrillator 10 from an OFF state to an ON state so that a defibrillation process using the automated external defibrillator 10 may proceed. However, since the conventional automated external defibrillator AED 10 is powered on manually by the user, there is a possibility of operation delay in an emergency situation, thereby causing inconvenience in proceeding with the defibrillation process in the emergency situation.
