Description

Automated external defibrillator and its CPR guidance mode setting method {AUTOMATED EXTERNAL DEFIBRILLATOR AND METHOD FOR SETTING CARDIOPULMONARY RESUSCITATION GUIDE MODES THEREOF}

The present invention relates to an automatic external defibrillator, and more particularly, to an automatic external defibrillator that allows a rescue team to perform CPR by selecting a guidance method for the CPR mode and a method for setting the CPR guidance mode will be.

Prompt cardiopulmonary resuscitation (CPR) and defibrillation for patients with cardiac arrest can increase the patient's survival rate. Automated defibrillators, which can easily perform defibrillation not only by medical personnel but also by non-medical personnel, are provided in public places such as multi-use facilities, schools, and public institutions. The automated external defibrillator analyzes and determines the patient's arrhythmia or cardiac dysrhythmia, that is, ventricular tachycardia (VT) and ventricular fibrillation (VF), by an electrocardiogram (ECG) automatic analysis device, and determines if the arrhythmia is When it occurs, defibrillation is performed by applying an electric shock to the patient automatically or semi-automatically through the defibrillation electrode.

An automated external defibrillator consists of a main body, a cover, a controller, two defibrillation electrodes or electrode pads, an electrocardiogram automatic analyzer, and a battery pack. The controller controls defibrillation by applying an electric shock through defibrillation electrodes attached to the patient when arrhythmia occurs in the patient.

Korean Patent Registration No. 10-1049273 'Automated External Defibrillator and Operation Method Thereof' discloses a voice guidance unit for guiding a rescuer through the treatment steps of a patient by voice, and a step for evaluating the execution level of each step of the guidance voice of the voice guidance unit.

Meanwhile, the automated defibrillator operates in pause mode and voice guidance for CPR. In the case of voice guidance of CPR, information on chest compressions is output, and chest compression speed is guided by a metronome sound effect. In the case of a trained first responder, voice guidance may confuse the rescuer in the course of treatment and may cause the voice guidance to be paused.

The recent guideline for CPR suggests CPR in which ventilation of CPR is omitted when the chest compression time that occurs during artificial respiration is delayed or when an infectious disease such as coronavirus infection-19 (COVID-19) is prevalent. are doing Therefore, there is a demand for an automatic defibrillator in which a rescuer can set an operation for CPR guidance.

The present invention is to solve the various problems of the automatic external defibrillator as described above, and a new automatic external defibrillator and its cardiopulmonary bypass that allow rescuers to quickly and accurately perform CPR by selecting a guide method for the CPR mode in the CPR mode. It is to provide a method for setting the resuscitation guidance mode.

According to one aspect of the present invention, an automated external defibrillator is provided. The automatic defibrillator according to the present invention performs defibrillation and CPR mode by attaching two defibrillation electrodes to a patient, and provides voice guidance for chest compressions for CPR, output of metronome sound effects for chest compression speed, and artificial defibrillation. Voice guidance mode that executes voice guidance for breathing, compression-only mode that outputs a metronome sound effect to guide the rate of continuous chest compressions, and mute mode that stops voice guidance for CPR and announces the remaining time until ECG analysis is completed a CPR guidance mode control unit executing any one of the modes; CPR mode setting means capable of setting any one of a voice explanation mode, a compression-only mode, and a mute mode; and a controller controlling the execution of the corresponding mode set by the CPR mode setting means.

A method for setting a CPR guidance mode of an automatic external defibrillator according to another aspect of the present invention includes executing the CPR mode; activating a CPR mode setting means; A voice explanation mode that executes voice guidance for chest compression for CPR, metronome sound effect sound output for chest compression speed, and voice guidance for artificial respiration by CPR mode setting means, and a metronome for guiding continuous chest compression speed setting one of a compression-only mode that outputs sound effects and a mute mode that stops voice guidance for CPR and guides the remaining time until electrocardiogram analysis is completed; and executing a corresponding mode set among a voice explanation mode, a compression-only mode, and a mute mode.

The automatic external defibrillator and the method for setting the CPR guide mode according to the present invention has an effect that the rescue team can quickly and accurately perform CPR by selecting a guide method for the CPR mode in the CPR mode. Therefore, it is effective to increase the survival rate of patients with cardiac arrest by omitting artificial respiration of CPR and performing CPR in situations where rescuers are skilled or infectious diseases such as COVID-19 are prevalent.
