Cardio-pulmonary resuscitation auxiliary system

Abstract

The invention discloses a cardio-pulmonary resuscitation auxiliary system, which comprises an ECG sensor, a PPG sensor, a pressure sensor, and a displacement sensor; an electrocardio ECG signal, a blood oxygen impulse wave signal, a pressing force signal and a pressing depth signal are correspondingly extracted from a pressed patient; four sensors are connected with an intelligent controller through a serial port, and the intelligent controller can process the signal through an internal uninterrupted external chest compression defibrillation rhythm identifying module, an external chest compression depth optimizing module and an autonomous circular identifying module, so as to obtain the autonomous circular recovery prompt information, individualized optimal compression depth prompt information, and uninterrupted external chest compression defibrillation rhythm prompt information of the pressed patient; these information can be displayed through a man-machine interactive interface or promoted in a voice form through a loudspeaker. The cardio-pulmonary resuscitation auxiliary system can provide an optimal auxiliary suggestion according to the vital signs of the patient, so that the cardio-pulmonary resuscitation quality is effectively improved.

Description

technical field [0001] The invention relates to the field of cardiopulmonary resuscitation, in particular to a cardiopulmonary resuscitation assisting system. Background technique [0002] Cardiovascular disease has become the main cause of human morbidity and death, many of which manifest as sudden cardiac death. This disease has become an important killer that threatens human life and health, and the most effective and direct medical method for this disease is cardiopulmonary resuscitation (CPR). CPR creates temporary artificial circulation by increasing intrathoracic pressure or directly squeezing the heart to create blood flow that allows oxygen to be delivered to the brain or other vital organs. The key to successful CPR is to perform high-quality CPR as early as possible. High-quality cardiopulmonary resuscitation is mainly reflected in the following three aspects: [0003] 1. Defibrillation rhythm identification for uninterrupted chest compressions; [0004] Studi...

AI Technical Summary

Problems solved by technology

[0012] The above-mentioned patents all have deficiencies. Although patent 201310685817.2 provides a method for real-time identification of ROSC during CPR, it cannot identify the ECG rhythm in real time during chest compressions, nor can it evaluate the current quality of cardiopulmonary resuscitation. Optimal CPR Advice

The latter four patents (patent 201380033138.5, patent 201510266747.6, patent 201110068162.5, and patent 200820145170.9) all evaluate the quality of current chest compressions and provide prompt information to assist correction, but they cannot recognize the ECG rhythm in real time, and there is no independent Circulatory reconstruction (ROSC) recognition function, unable to judge whether it is necessary to interrupt chest compressions for electric shock defibrillation, or whether it is necessary to terminate cardiopulmonary resuscitation

And the prompt information given by patent 201380033138.5, patent 201510266747.6 and patent 200820145170.9 did not consider the individual differences of patients, and all followed the fixed cardiopulmonary resuscitation guidelines as the gold standard, so that it was impossible to implement personalized optimal cardiopulmonary resuscitation operations
