[0006]
[0001] The present invention relates to an intelligent defibrillator operation system and method using motion sensing. More specifically, it relates to an intelligent defibrillator operation system and method using motion sensing that can control the operation of an automated external defibrillator (AED) based on the gradient, acceleration, gradient, and holding time of acceleration change of the AED.
Background Art
[0002] As shown in FIG. 1, a conventional automated external defibrillator 10 includes a power supply unit 11, a display unit 12, an audio output unit 13, electrodes 14, a defibrillation pulse unit 15, and a control unit 16.
[0003] The defibrillation pulse unit 15 is connected to the electrodes 14. After the electrodes 14 are attached to a part of the patient's body (preferably the heart side) by the user, the patient's ECG (electrocardiogram) signal is input and transmitted to the defibrillation pulse unit 15, and the defibrillation pulse unit 15 transfers the ECG signal to the control unit 16.
[0004] Also, in the process of analyzing the patient's ECG signal, when an abnormal pattern (e.g., dangerous heart rhythms such as ventricular fibrillation, pulseless ventricular tachycardia, asystole, bradycardia, tachycardia, etc.) in the ECG signal is analyzed, the control unit 16 controls the display unit 12 or the audio output unit 13 to generate a warning notification and guide the user with the patient status information.
[0005] Furthermore, 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 signal is detected.
[0006] Such conventional automated external defibrillators 10 are usually stored in a designated location, and when an emergency situation occurs, the user moves the automated external defibrillator 10 to the patient while holding it in their hand at the designated location. When the user presses a button or opens the cover, the power supply unit 11 switches the power of the automated external defibrillator 10 from the off state to the on state so that power is applied and the defibrillation process using the automated external defibrillator 10 can proceed.
[0007] However, conventional automated external defibrillators 10 have a problem in that they require manual power supply by the user, which can lead to delays in operation in emergency situations, making it inconvenient to perform the defibrillation process in emergency situations.

[0008] [Patent Document 1] Republic of Korea Published Patent Gazette No. 10-2024-0071505 (Published May 23, 2024) [Overview of the project] [Problems that the invention aims to solve]
[0009] Therefore, the present invention has been made to solve the above-mentioned problems, and the object of the present invention is to provide an intelligent defibrillator operating system and method using motion sensing that can control the operation of an automated external defibrillator (AED) based on the gradient of the AED, acceleration, and the holding time of the gradient and acceleration change.
[0010] Another object of the present invention is to provide an intelligent motion-sensing defibrillator operating system and method that enables the power supply of the automated external defibrillator to be automatically applied by the movement of the automated external defibrillator, and to intelligently control the automated external defibrillator to automatically proceed with a defibrillation pulse generation-based defibrillation process, including screen and audio output for guiding the use of the automated external defibrillator, and depending on whether the automated external defibrillator is movable and whether it can reach a position for use to advance the defibrillation process.
[0011] However, the technical problems that this invention aims to solve are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those with ordinary skill in the art to which this invention belongs from the following description. [Means for solving the problem]
[0012] An intelligent defibrillator activation system using motion sensing according to one embodiment of the present invention for achieving the above-mentioned objectives is an intelligent defibrillator activation system for controlling the operation of an automated external defibrillator, comprising: a power supply unit for supplying power to the automated external defibrillator; a display unit equipped with a display for outputting warning notifications to guide the user of the automated external defibrillator on how to use the automated external defibrillator, the defibrillation process using the automated external defibrillator, and that a defibrillation pulse-based electric shock is necessary for the patient; and an audio output unit equipped with a speaker. The invention is characterized by comprising: an electrode attached to a part of the patient's body to receive the patient's ECG (electrocardiogram) signal; a defibrillation pulse unit that transmits the patient's ECG signal via the electrode; a sensing unit that senses the gradient change amount (△θ), gradient holding time, acceleration change amount (△a), gradient value (θ), gradient and acceleration holding time of the automated external defibrillator; and a control unit that analyzes the patient's ECG signal transmitted by the defibrillation pulse unit and controls the operation of the automated external defibrillator based on the gradient, acceleration, gradient and acceleration change holding time of the automated external defibrillator.
[0013] The defibrillation pulse unit generates a defibrillation pulse to deliver an electric shock to the patient when the control unit analyzes an abnormal pattern in the patient's ECG signal, the electrodes deliver the electric shock from the defibrillation pulse to the patient, and the display unit and audio output unit output patient status information and information regarding the procedure for subsequent measures (CPR) to be performed after the defibrillation process.
[0014] The abnormal patterns within the ECG signal are ECG signals that match rhythm types such as ventricular fibrillation, pulseless ventricular tachycardia, acontraction, bradycardia, and tachycardia.
[0015] The patient status information includes the type of cardiac rhythm of the patient for determining whether the patient is eligible for defibrillation or not, the readiness status of the automated external defibrillator for defibrillation of the patient, whether the patient's movement can be detected, and whether a defibrillation pulse-based electric shock is required.
[0016] The control unit controls the power supply unit so that power is supplied to the automated external defibrillator based on the gradient change amount (△θ), gradient holding time, and acceleration change amount (△a) of the automated external defibrillator.
[0017] The control unit controls the display unit and the audio output unit based on the acceleration change amount (△a) and the gradient change amount (△θ) while power is applied to the automated external defibrillator and the power of the automated external defibrillator is kept on, so that the automated external defibrillator is kept in an operational standby state before proceeding with the defibrillation process.
[0018] When the automated external defibrillator (AED) is in standby mode, the display unit and audio output unit do not output any screen or audio to guide the user on how to use the AED.
[0019] The control unit determines whether the automated external defibrillator can reach the usage position for the user to proceed with the defibrillation process, based on the gradient value (θ), acceleration change amount (△a), gradient, and acceleration holding time (stopping holding time) of the automated external defibrillator.
[0020] When it is determined that the automated external defibrillator has reached the usage position, the control unit controls the display unit and the audio output unit so that the defibrillation process using the automated external defibrillator proceeds.
[0021] The display unit outputs the defibrillation process using the automated external defibrillator for guiding the user from the display, and the audio output unit outputs an audio for guiding the usage method of the automated external defibrillator from the speaker.
Advantages of the Invention
[0022] In the present invention, since the power supply of the automated external defibrillator is automatically applied by the movement of the automated external defibrillator, in an emergency situation, the defibrillation process can proceed without delaying the operation of the automated external defibrillator.
[0023] Further, in the present invention, depending on whether the automated external defibrillator can be moved and whether it can reach the usage position for performing the defibrillation process, a screen and audio output for guiding the use of the automated external defibrillator, and a defibrillation process based on defibrillation pulse generation automatically proceed, thereby providing convenience in the defibrillation process.

[0031] Motion-sensing intelligent defibrillator activation system The following describes in detail an intelligent defibrillator activation system 100 using motion sensing according to one embodiment of the present invention, with reference to the attached drawings.
[0032] Figure 2 is an illustrative diagram showing an intelligent defibrillator activation system using motion sensing according to one embodiment of the present invention.
[0033] As shown in Figure 2, the intelligent defibrillator operating system 100 according to one embodiment of the present invention is a system configured in an automated external defibrillator (AED) and includes a power supply unit 110, a display unit 120, an audio output unit 130, electrodes 140, a defibrillation pulse unit 150, a sensing unit 160, and a control unit 170.
[0034] In one embodiment, when an emergency situation occurs and the user starts moving the power supply unit 110 from a predetermined location (e.g., a storage box inside a subway station), the sensing unit 160 senses information in real time and applies power to the automated external defibrillator, changing the power supply of the automated external defibrillator from the off state to the on state.
[0035] In other words, the power supply unit 110 can automatically supply power to the automated external defibrillator based on information sensed in real time by the sensing unit 160, rather than requiring the user to manually supply power to the automated external defibrillator.
[0036] In one embodiment, the display unit 120 and the audio output unit 130 output information regarding the method of using the automated external defibrillator, the defibrillation process using the automated external defibrillator, warning notifications that the patient needs a defibrillation pulse-based electric shock, patient status information, and the method of performing subsequent measures (CPR) after the defibrillation process.
[0037] In one embodiment, the display unit 120 is provided with a display (not shown), and in the process of the control unit 170 analyzing the patient's ECG (electrocardiogram) signal, when it analyzes abnormal patterns in the ECG signal (e.g., ECG signals that match dangerous cardiac rhythm types such as ventricular fibrillation, pulseless ventricular tachycardia, acontraction, bradycardia, tachycardia, etc.), it can guide the patient through the display information on the patient's condition and the procedure for subsequent measures (CPR) to be performed after the defibrillation process. The display outputs information regarding the patient's condition and the procedure for subsequent measures (CPR).
[0038] Here, patient status information includes the patient's cardiac rhythm type (eligible for defibrillation or not eligible for defibrillation), the patient's readiness for defibrillation (electrically charged or ready for electric shock), whether the patient's movement can be detected, and whether a defibrillation pulse-based electric shock is required.
[0039] In one embodiment, the audio output unit 130 is equipped with a speaker (not shown), and when the control unit 170 analyzes the patient's ECG signal and detects an abnormal pattern in the ECG signal, it can inform the user through the speaker that the patient needs a pulse-based defibrillation shock, and the speaker can generate a warning notification to inform the user that a pulse-based defibrillation shock is needed.
[0040] In one embodiment, the electrode 140 is connected to a defibrillation pulse generation unit 150, and while power from the power supply unit 110 is supplied to the defibrillation pulse generation unit 150, it is attached to a part of the patient's body (preferably the side of the heart), and the patient's ECG signal is input and transmitted to the defibrillation pulse generation unit 150.
[0041] Furthermore, the electrode 140 provides the patient with an electric shock from the defibrillation pulse generated by the defibrillation pulse generation unit 150, so that the defibrillation process of the patient can proceed using an automated external defibrillator.
[0042] In one embodiment, the defibrillation pulse unit 150 is connected to an electrode 140 and a control unit 170, and transmits the patient's ECG signal, measured by the electrode 140 which is in contact with a part of the patient's body, to the control unit 170.
[0043] Furthermore, the defibrillation pulse unit 150 generates a defibrillation pulse to deliver an electric shock to the patient if the control unit 170, in the process of analyzing the patient's ECG signal, detects an abnormal pattern in the ECG signal.
[0044] In one embodiment, the sensing unit 160 includes a gradient sensor, a gyro sensor, and a 3-axis accelerometer, and senses the gradient change amount (△θ), gradient holding time, acceleration change amount (△a), gradient value (θ), gradient and acceleration holding time (stop holding time) of the automated external defibrillator in real time.
[0045] In one embodiment, the control unit 170 controls the power supply unit 110 so that power is supplied to the automated external defibrillator (AFF) based on the gradient change amount (△θ), gradient holding time, and acceleration change amount (△a) of the AFF, which are sensed in real time by the sensing unit 160.
[0046] Furthermore, while power is applied to the automated external defibrillator (AED) and the AED remains powered on, the control unit 170 controls the display unit 120 and the audio output unit 130 based on the acceleration change amount (△a) and gradient change amount (△θ) sensed in real time by the sensing unit 160, so that the AED remains in an operational standby state before proceeding with the defibrillation process.
[0047] Here, the display unit 120 and the audio output unit 130 do not output any screen or audio to guide the user on how to use the automated external defibrillator when the automated external defibrillator is in standby mode.
[0048] Furthermore, the control unit 170 determines whether the automated external defibrillator (AFF) can reach the user's position (patient side) for the user to proceed with the defibrillation process, based on the gradient value (θ), acceleration change amount (△a), gradient, and acceleration holding time (stop holding time) of the AFF that the sensing unit 160 senses in real time.
[0049] Furthermore, when the control unit 170 determines that the automated external defibrillator (AED) has reached the position for use, it controls the display unit 120 and the audio output unit 130 so that the defibrillation process using the AED proceeds.
[0050] Here, the display unit 120 and the audio output unit 130 output instructions on how to use the automated external defibrillator and the defibrillation process using the automated external defibrillator to guide the user.
[0051] Furthermore, in the process of analyzing the patient's ECG signal, when the control unit 170 begins to analyze abnormal patterns within the patient's ECG signal, it controls the display unit 120 and the audio output unit 130 to guide the user through patient status information and the procedure for subsequent measures (CPR) to be performed after the defibrillation process.
[0052] Here, the display unit 120 and the audio output unit 130 output patient status information and information regarding the procedure for subsequent measures (CPR) to be performed after the defibrillation process to the user.
[0053] Furthermore, the display unit 120 may be provided with an operating means (not shown) on one side of the display to forcibly operate the automated external defibrillator (AFF) in case the AFF is kept in an operating standby state due to a recognition (judgment) error by the control unit 170, even if physical conditions such as the gradient value (θ), acceleration change amount (△a), gradient and acceleration holding time (stop holding time) of the AFF meet the operating conditions for the AFF to proceed with the defibrillation process.
[0054] Method for operating an intelligent defibrillator using motion detection The following describes in detail, with reference to the attached drawings, an intelligent defibrillator activation method using motion sensing according to one embodiment of the intelligent defibrillator activation system 100 described above.
[0055] 1) Power application method Figure 3 is a flowchart showing a power supply application method according to one embodiment of the present invention.
[0056] As shown in Figure 3, the control unit 170 determines whether the automated external defibrillator (AED) can be physically moved, and if predetermined conditions are met, controls the power supply unit 110 so that power is supplied to the AED from the power supply unit 110.
[0057] First, the control unit 170 determines whether the amount of change in the gradient of the automated external defibrillator (ATF), which is sensed in real time by the sensing unit 160, is within a first set angle in order to sense whether the ATF has been physically moved by the user from its designated storage location (S110).
[0058] In one embodiment, the first set angle range is 1 to 20°, preferably 5° or more.
[0059] Here, if the gradient change amount (△θ) of the automated external defibrillator is less than or equal to the first set angle (e.g., 5°) (S110-NO), the control unit 170 determines that no physical movement of the automated external defibrillator will occur, and controls the power supply unit 110 so as not to apply power to the automated external defibrillator, and the automated external defibrillator is kept in a power-off state (S120).
[0060] In contrast, if the gradient change amount (△θ) of the automated external defibrillator (AED) is greater than or equal to a first set angle (e.g., 5°) (S110-YES), the control unit 170 determines whether the gradient holding time of the AED, as sensed in real time by the sensing unit 160, is within the first set time in order to sense whether sustained motion has occurred in the AED (S130).
[0061] In one embodiment, the first setting time is 100 milliseconds (hereinafter, ms) to 1 second (hereinafter, sec), and preferably 500 ms or more.
[0062] Here, if the gradient holding time of the automated external defibrillator is less than or equal to the first set time (e.g., 500 ms) (S130-NO), the control unit 170 determines that a temporary movement has occurred in the automated external defibrillator and controls the power supply unit 110 so as not to apply power to the automated external defibrillator, and the automated external defibrillator is kept in a power-off state (S140).
[0063] In contrast, if the gradient holding time of the automated external defibrillator is greater than or equal to the first set time (e.g., 500 ms) (S130-YES), the control unit 170 determines whether the amount of acceleration change (△a) of the automated external defibrillator, as sensed in real time by the sensing unit 160 for physical movement or vibration detection of the automated external defibrillator, is within a set value (unit: g) (S150).
[0064] In one embodiment, the set amount range is 0.1g to 1.5g (gravitational acceleration), and preferably 0.1g or more.
[0065] Here, if the acceleration change amount (△a) of the automated external defibrillator (AFF) is less than or equal to a set value (e.g., 0.1g) (S150-NO), the control unit 170 determines that no physical movement or vibration is detected in the AFF, and controls the power supply unit 110 so as not to apply power to the AFF, and the AFF is kept in a power-off state (S160).
[0066] In contrast, if the acceleration change amount (△a) of the automated external defibrillator (AED) is greater than or equal to a set value (e.g., 0.1g) (S150-YES), the control unit 170 controls the power supply unit 110 to supply power to the AED, and the AED is converted to a power-on state (S170).
[0067] In other words, in one embodiment, the control unit 170 controls the power supply unit 110 to supply power to the automated external defibrillator (AED) if the gradient change amount (△θ) of the AED detected in real time by the sensing unit 160 is greater than or equal to a first set angle, the gradient holding time of the AED is greater than or equal to a first set time, and furthermore, the acceleration change amount (△a) of the AED is greater than or equal to a set value.
[0068] 2) First method of standby and defibrillator operation Figure 4 is a flowchart showing a first operation standby and defibrillator activation method according to one embodiment of the present invention.
[0069] As shown in Figure 4, the control unit 170 determines whether or not sustained motion has occurred in the automated external defibrillator (AED) to which power has been applied under predetermined conditions in a step described later (S210), and then controls the display unit 120 and the audio output unit 130 to determine whether or not the defibrillation process will proceed in the AED.
[0070] First, the control unit 170 determines whether or not sustained movement occurs in the powered-on automated external defibrillator by determining whether the acceleration change amount (△a) of the powered-on automated external defibrillator is less than or equal to a set value (e.g., 0.1g), or whether the gradient change amount (△θ) is less than or equal to a first set angle (e.g., 5°) (S210).
[0071] Here, if the amount of acceleration change (△a) of the powered-up automated external defibrillator is less than or equal to a set value (e.g., 0.1g), or if the amount of gradient change (△θ) is less than or equal to a first set angle (e.g., 5°) (S210-YES), the control unit 170 determines that no sustained movement occurs in the automated external defibrillator and that the automated external defibrillator has reached the usage position (patient side) for use (S220).
[0072] Thereafter, the control unit 170 controls the display unit 120 and the audio output unit 130 so that a screen and audio output indicating how to use the automated external defibrillator are output from the display unit 120 and the audio output unit 130 in order to guide the user on how to use the automated external defibrillator (S230).
[0073] In contrast, if the acceleration change amount (△a) of the powered-on automated external defibrillator (AED) is greater than or equal to a set value (e.g., 0.1g), or if the gradient change amount (△θ) is greater than or equal to a first set angle (e.g., 5°) (S210-NO), the control unit 170 can determine that the AED has not reached the usage position (patient side) for proceeding with the defibrillation process, and that continuous movement is occurring in the AED. The control unit 170 maintains the AED's power on and controls the display unit 120 and the audio output unit 130 so that no screen or audio is output from the display unit 120 and the audio output unit 130 to guide the user on how to use the AED (S240).
[0074] In other words, in one embodiment, the control unit 170 can determine that there is no movement of the automated external defibrillator (AFF) when the amount of acceleration change (△a) of the AFF with power applied is less than or equal to a set value (e.g., 0.1g), or the amount of gradient change (△θ) is less than or equal to a first set angle (e.g., 5°), and can control the display unit 120 and the audio output unit 130 so that the defibrillation process proceeds.
[0075] 3) Second method of standby and defibrillator operation Figure 4 is a flowchart showing a second operation standby and defibrillator activation method according to one embodiment of the present invention.
[0076] As shown in Figure 5, after the operation standby state holding stage (S240) in Figure 4, the control unit 170 can control the display unit 120 and the audio output unit 130 to determine whether or not a sustained movement has occurred in the automated external defibrillator to which power has been applied under predetermined conditions in the stages described later (S310, S330, S350), so as to whether or not the defibrillation process in the automated external defibrillator will proceed.
[0077] First, the control unit 170 determines whether or not sustained movement of the automated external defibrillator occurs, by using a horizontal floor as a reference, whether or not the gradient value (θ) of the powered automated external defibrillator is within a second set angle (S310).
[0078] In the aforementioned step (S310), the second setting angle is 0 to 45° relative to the horizontal floor, preferably 15° relative to the horizontal floor.
[0079] Here, if the gradient value (θ) of the powered automated external defibrillator (AED) relative to a horizontal floor is greater than or equal to a second set angle (e.g., 15° relative to a horizontal floor) (S310-NO), the control unit 170 can determine that the AED has not reached the usage position (patient side) for proceeding with the defibrillation process and that continuous movement is occurring in the AED. The control unit 170 keeps the AED powered on and controls the display unit 120 and the audio output unit 130 so that no screen or audio is output from the display unit 120 and the audio output unit 130 to guide the user on how to use the AED (S320).
[0080] In contrast, if the gradient value (θ) of the automated external defibrillator to which power is applied relative to a horizontal floor is less than or equal to a second set angle (e.g., 15° relative to a horizontal floor) (S310-YES), the control unit 170 determines whether the change in acceleration amount (△a) of the automated external defibrillator to which power is applied is greater than or equal to a set value (e.g., 0.1g) in order to sense whether sustained motion has occurred in the automated external defibrillator (S330).
[0081] Here, if the amount of acceleration change (△a) of the powered-up automated external defibrillator is less than or equal to a set value (e.g., 0.1g) (S330-NO), the control unit 170 determines that no sustained motion is occurring in the automated external defibrillator, keeps the power of the automated external defibrillator ON, and controls the display unit 120 and the audio output unit 130 so that no screen or audio is output from the display unit 120 and the audio output unit 130 to guide the user on how to use the automated external defibrillator (S340).
[0082] In contrast, if the amount of acceleration change (△a) of the powered external defibrillator is greater than or equal to a set value (e.g., 0.1g) (S330-YES), the control unit 170 determines whether the gradient value (θ) of the powered external defibrillator is greater than or equal to a second set angle, and whether the time during which the state in which the amount of acceleration change (△a) is greater than or equal to a set value is maintained is greater than or equal to a second set time, in order to sense whether sustained motion is occurring in the external defibrillator (S350).
[0083] In the aforementioned step (S350), the second setting time is 500ms to 2 seconds, preferably 1 second.
[0084] Here, if the gradient value (θ) of the powered-on automated external defibrillator is greater than or equal to the second set angle, and the time during which the acceleration change amount (△a) remains greater than or equal to the set value is greater than or equal to the second set time (e.g., 1 sec) (S350-NO), the control unit 170 can determine that the automated external defibrillator has not reached the usage position (patient side) for proceeding with the defibrillation process, and that continuous movement is occurring in the automated external defibrillator. The control unit 170 then keeps the power of the automated external defibrillator ON and controls the display unit 120 and the audio output unit 130 so that no screen or audio is output from the display unit 120 and the audio output unit 130 to guide the user on how to use the automated external defibrillator (S360).
[0085] In contrast, if the gradient value (θ) of the powered external defibrillator is less than or equal to the second set angle, and the time during which the acceleration change amount (△a) remains above the set value is less than or equal to the second set time (e.g., 1 sec) (S350-YES), the control unit 170 can determine that no sustained movement occurs in the external defibrillator and that the external defibrillator has reached the use position (patient side) for use of the external defibrillator (S370).
[0086] Thereafter, the control unit 170 controls the display unit 120 and the audio output unit 130 so that a screen and audio message guiding the user on how to use the automated external defibrillator are output from the display unit 120 and the audio output unit 130 (S380).
[0087] In other words, in one embodiment, after the operation standby state holding stage (S240) in Figure 4, the control unit 170 determines that there is no movement of the automated external defibrillator (AED) and controls the display unit 120 and the audio output unit 130 so that the defibrillation process proceeds if the time for which the AED maintains a state in which the AED maintains a gradient value (θ) of the AED with power applied to a horizontal floor is less than or equal to a second set angle (e.g., 15° with respect to a horizontal floor), the acceleration change amount (△a) of the AED with power applied is less than or equal to a set value (e.g., 0.1g), the gradient value (θ) is less than or equal to the second set angle range, and the acceleration change amount (△a) is greater than or equal to a set amount is less than or equal to a second set time (e.g., 1 sec).
[0088] 4) Defibrillation process progress method Figure 6 is a flowchart showing a method for carrying out the defibrillation process according to one embodiment of the present invention.
[0089] As shown in Figure 6, when the user receives a screen and audio from the display unit 120 and the audio output unit 130 to guide them on how to use the automated external defibrillator, they refer to the screen and audio and attach the electrodes 140 to a part of the patient's body (on the heart side). The electrodes 140 attached to the part of the patient's body receive the patient's ECG (electrocardiogram) signal (S410).
[0090] Thereafter, the control unit 170 analyzes the ECG signal of the patient to which the electrodes 140 have been input using the defibrillation pulse unit 150 (S420), and can detect abnormal patterns in the patient's ECG signal (e.g., ECG signals that match dangerous cardiac rhythm types such as ventricular fibrillation, pulseless ventricular tachycardia, acontraction, bradycardia, and tachycardia) (S430).
[0091] If, at this point, no abnormal pattern (e.g., an ECG signal that matches a dangerous cardiac rhythm type such as ventricular fibrillation, pulseless ventricular tachycardia, acontraction, bradycardia, or tachycardia) is detected from the patient's ECG signal (S430-NO), the control unit 170 controls the display unit 120 so that information regarding the patient's condition and the subsequent measures (CPR) are output from the display of the display unit 120 and the speaker of the audio output unit 130 to inform the user of the patient's condition and subsequent measures (CPR) (S440).
[0092] In the aforementioned step (S440), among the patient status information output from the display unit 120 and the audio output unit 130, it is desirable that the patient's cardiac rhythm type is a cardiac rhythm not subject to defibrillation, and that defibrillation pulse-based electrical shock is not required.
[0093] In contrast, if an abnormal pattern (e.g., an ECG signal that matches a dangerous cardiac rhythm type such as ventricular fibrillation, pulseless ventricular tachycardia, acontraction, bradycardia, or tachycardia) is detected from the patient's ECG signal (S430-YES), the control unit 170 controls the display unit 120 and the voice output unit 130 so that a warning notification is output from the voice output unit 130 informing the user that a defibrillation pulse-based electric shock is necessary, and further controls the display unit 120 so that patient status information is output from the display of the display unit 120 in order to inform the user of the patient's status information (S450).
[0094] In the aforementioned step (S450), among the patient status information output from the display unit 120, the patient's cardiac rhythm type is a cardiac rhythm that is subject to defibrillation, and in the case of a cardiac rhythm that is subject to defibrillation, it is desirable that a defibrillation pulse-based electrical shock is required.
[0095] Thereafter, the defibrillation pulse unit 150 generates defibrillation pulses for electric shock in order to carry out the defibrillation process using an automated external defibrillator (S460).
[0096] Thereafter, the electrodes 140 attached to a part of the patient's body provide the patient with an electric shock based on the defibrillation pulse generated by the defibrillation pulse unit 150, allowing the defibrillation process to proceed. The control unit 170 controls the display unit 120 and the voice output unit 130 so that they output patient status information and information regarding the method of proceeding with subsequent measures (CPR) to inform the user of the patient's condition and subsequent measures (CPR) (S470).
[0097] Thereafter, the user can respond to the patient's emergency situation by performing subsequent measures according to the sequence of subsequent measures (CPR) output to the display unit 120 and the audio output unit 130.
[0098] Effects according to the present invention The intelligent defibrillator activation system 100 of the present invention automatically applies power to the automated external defibrillator (AED) based on the movement of the AED, allowing the defibrillation process to proceed without delaying the operation of the AED in emergency situations.
[0099] Furthermore, the intelligent defibrillator operating system 100 of the present invention can provide convenience in the defibrillation process by automatically providing a screen and audio output to guide the use of the automated external defibrillator, and by automatically proceeding with the defibrillation pulse generation-based defibrillation process, depending on whether the automated external defibrillator is movable and whether it can reach the usage position for proceeding with the defibrillation process.
