Description

ECG detection circuit and ECG analysis algorithm inspection apparatus and method

The present invention relates to an electrocardiogram (ECG) detection circuit used in an automatic defibrillator and a manual defibrillator, and an apparatus and a method for checking an electrocardiogram detection circuit and an electrocardiogram analysis algorithm for testing the operation of an electrocardiogram analysis algorithm.

A defibrillator is a defibrillator called a defibrillator that performs resuscitation to restore normal pulses by allowing high voltage current to flow through the heart for short periods of time such as ventricular fibrillation, atrial fibrillation, atrial fibrillation, and ventricular tachycardia. Two unipolar poles are placed on the chest and the cardiac part of the chest wall to allow current to flow. For arrhythmia other than ventricular fibrillation, a device with an electrocardiogram is required.

The Automated Extemal Defibrillator (AED) is a device that allows CPR while receiving voice guidance. In general, the AED is designed to automatically check the patient's heart condition to give an electric shock.

Because a heart attack stops blood circulation throughout the body, it can lead to death or serious brain damage if not taken immediately. In particular, the brain can be permanently damaged even if the blood supply is interrupted for 4-5 minutes.

Cardiopulmonary resuscitation (CPR) is an emergency treatment that artificially circulates blood and helps breathing when a heart attack occurs (cardiac arrest). When acute cardiac arrest occurs when a patient suddenly stops, CPR is performed by first aid. In general, CPR recovers 20% of normal blood flow, while AED can recover 100%, so AED can restore heart rate to normal and increase survival rate of cardiac arrest patients up to 70%.

The human heart has a command system that operates the myocardium in a certain order in order to release blood effectively. The heart supplies blood to the arteries by repeating contraction and expansion in a certain sequence. If the heart does not move in a certain order, the heart cannot efficiently supply blood to the arteries.

Therefore, cardiopulmonary resuscitation using AED, which supplies blood to the arteries by repeatedly contracting and expanding the heart in a certain order and causes the heart to move according to the order, greatly affects the survival rate after the accident.

Therefore, in order to operate the defibrillator properly, the reliability of the device for detecting and analyzing an electrocardiogram is important.

The databases may include de-noise signals and de-noise signals.

The electrocardiogram generator 260 connects with a predetermined electrocardiogram database of the various electrocardiogram databases, receives an electrocardiogram signal therefrom, and converts the received electrocardiogram signal into a small size, such as an electrocardiogram signal detected from an electrocardiogram electrode mounted on a patient. It is produced by outputting ECG signal with noise. To this end, the ECG generator 260 may include a mixing device (or multiplier) for mixing an amplifier (or attenuator) with noise. The output of the ECG generator 260 is transmitted to an input terminal of the ECG detection circuit 330 to be tested.

The electrocardiogram generator 260 and the electrocardiogram simulator 230 form the test signal generator 200.

The test unit 300 is a portion on which the ECG detection circuit 330 or the ECG analyzer 360 to be tested is mounted, and when the ECG detection circuit 330 and the ECG analyzer 360 are both mounted, the ECG detection circuit 330. Is passed to the ECG analyzer 360.

The input terminal of the ECG detection circuit 330 may select either the output terminal of the ECG generator 260 or the external input port 290. Here, the external input port 290 is a connection port to which the output of the ECG electrode 190 mounted on the subject is connected or to read ECG data of the external memory 195.
