Automatic cardiopulmonary resuscitation device

Abstract

The present invention relates to an automatic cardiopulmonary resuscitation (CPR) device which, even in the middle of performing cardiopulmonary resuscitation, can measure an electrocardiogram and oxygen saturation, can measure an electroencephalogram so as to detect in real time a brain activity indicative of the degree of blood circulation in the brain, has a defibrillation function, can use a brain activity index as a CPR signal indicating the degree of cardiopulmonary resuscitation, and can remotely monitor biometric signals at a pre-hospital stage. The present invention provides a cardiopulmonary resuscitation device comprising: an electroencephalogram detection unit for detecting an electroencephalogram signal from the frontal lobe; and a calculation processing unit for detecting a brain activity index, which is used as a CPR signal indicating the degree of cardiopulmonary resuscitation, from the electroencephalogram signal received from the electroencephalogram detection unit, wherein the calculation processing unit derives, as the brain activity index, one or more of the burst suppression ratio (BSR), the beta ratio, and the SynchFastSlow (relative synchrony of fast and slow wave, SFS). The calculation processing unit eliminates noise from the electroencephalogram signal received from the electroencephalogram detection unit, and derives the beta ratio from the electroencephalogram signal, from which noise has been eliminated, using the following formula: Beta Ratio = log[spectral power (30-47 Hz) / spectral power (11-20 Hz)] (where, spectral power (30-47 Hz) denotes the spectral power in the 30-47 Hz band of the electroencephalogram, and spectral power (11-20 Hz) denotes the spectral power in the 11-20 Hz band of the electroencephalogram).

Description

technical field [0001] The present invention relates to a cardiopulmonary resuscitation device that measures electrocardiogram and oxygen saturation during a cardiopulmonary resuscitation process to detect brain activity as the degree of blood circulation in the brain in real time by measuring electroencephalogram, said cardiopulmonary resuscitation device is equipped with defibrillation function, using an index of brain activity as a CPR signal indicative of the degree of cardiopulmonary resuscitation, and enabling remote monitoring of biosignals during pre-hospital steps. Background technique [0002] Cardiopulmonary resuscitation (CPR) is an emergency treatment that occurs when a heart attack (cardiac arrest) [0003] During an attack, cardiopulmonary resuscitation assists breathing by artificially circulating blood. When the patient's heart stops beating in an acute cardiac arrest, cardiopulmonary resuscitation must be performed as a first aid. That is, performing artif...

[0012] However, Korean Laid-Open Patent Publication No. 10-2011-0014186 does not disclose details of calculation processing for oxygen saturation, ECG data, EEG data, etc., parameters extracted by calculation processing, and using the extracted data to control motors or Methods of automated external defibrillators, in addition, the apparatus for cardiopulmonary resuscitation excluding apparatus for detection and analysis of oxygen saturation, ECG and EEG

[0013] Usually, in emergency situations where CPR equipment is used, people panic, and in this situation, it is not easy to find measuring equipment for oxygen saturation, ECG and EEG, and it is not easy to put each of ECG, EEG Electrodes are attached to the patient in place for measurement
