Description

A defibrillation system to produce dual sequential defibrillation shocks The present invention relates to a defibrillation system that generates a double consecutive defibrillation shock, wherein two pairs of pad portions, namely a first pad portion and a second pad portion, are formed using four electrodes attached to different locations on the patient's chest to increase the resuscitation rate, and the first pad portion and the second pad portion are used alternately to provide two consecutive defibrillation shocks. When cardiac arrest occurs, blood circulation to the entire body ceases, so failure to take immediate action can lead to death or severe brain damage. In particular, the brain can be permanently damaged if blood supply is interrupted for just 4 to 5 minutes. The most common cause of cardiac arrest is a heart rhythm disorder called ventricular fibrillation, which is very dangerous because it causes the heart to stop pumping blood and cut off the blood supply to the brain and other vital organs. However, ventricular fibrillation can often be successfully treated by applying an electric shock to the heart through a procedure called defibrillation. Generally, an Automated External Defibrillator (AED) is a device that automatically eliminates cardiac fibrillation. It is a device that restores the heartbeat to normal by delivering an electric shock from the outside when a sudden cardiac arrest (SCA) occurs, which is a phenomenon in which the heart stops beating and blood flow to tissues is interrupted, thereby cutting off the supply of oxygen and other substances essential for biological activity. Dual sequential defibrillation (DSD) methods, which apply two consecutive electric shocks (defibrillation shocks) with a time difference of less than one second rather than applying a single shock to increase the survival rate, have been researched and developed for a long time. For example, U.S. Patent No. 06327500, filed on November 15, 1999, is a dual shock atrial defibrillator configured to deliver a second atrial defibrillation pulse 0 to 500 milliseconds after a first defibrillation pulse. In addition, prior patents related to dual continuous defibrillators include U.S. Patent No. 10632320, U.S. Patent No. 20210420, U.S. Patent Publication No. 2018/0280709, etc. Generally, a defibrillator delivers a defibrillation shock (electric shock) to a patient using high-voltage energy, that is, high-voltage current. To do this, a high-voltage capacitor is required to charge the high voltage, and it takes a certain amount of time to charge this high-voltage capacitor. Therefore, in the dual continuous defibrillation (DSD) method, which delivers a defibrillation shock with a time difference of less than one second, two high-voltage capacitors must be used to generate high-voltage energy for two consecutive electric shocks. As a prior art patent, Korean registered patent No. 10-1997369 relates to an automated external defibrillator for double electric shock, which applies two consecutive electric shocks (defibrillation shocks) at intervals of 3 to 5 seconds, which is different from the general double consecutive defibrillation method. Korean registered patent No. 10-1997369 is equipped with a capacitor unit consisting of two capacitors, and also includes a first switch between the electrode and the high-voltage control unit, and a second switch between the high-voltage control unit and the capacitor unit. In particular, the second switch selectively transmits high-voltage energy from the first capacitor (310) and the second capacitor (320) to the high-voltage control unit. In general, switches can generate noise due to switching operations and cause damage due to malfunctions; therefore, in the circuits of defibrillators handling high-voltage energy, it may be relatively better in terms of safety and cost to avoid using switches whenever possible. In particular, when a double continuous defibrillation shock is applied using only a pair of pads fixed in a specific position, the patient may suffer significant organ damage even if resuscitation is achieved, and it is also necessary to change the position of the electrode pads placed on the chest to increase the success rate of resuscitation by considering the blood flow path within the heart, cardiac polarization, etc. Accordingly, the present invention proposes a defibrillation system that generates a double continuous defibrillation shock by forming two pairs of pad sections, namely a first pad section and a second pad section, with four electrodes attached to different locations on the patient's chest to increase resuscitation, and by using the first pad section and the second pad section alternately to continuously provide a double continuous defibrillation shock. FIG. 1 is an explanatory diagram for schematically illustrating a defibrillation system that generates a double continuous defibrillation shock according to the present invention.
