An integrated first aid device for sudden cardiac arrest

Abstract

The invention discloses an integrated first aid device for sudden cardiac arrest. The device includes: a microprocessor simultaneously sends an instruction to start working to an external defibrillation module, a chest compression module, and an auxiliary breathing module; the external chest compression module, the auxiliary breathing module The module performs chest compressions and assisted ventilation according to the ratio of 30:2; the external defibrillation module collects ECG signals, and the microprocessor filters out the interference noise of the ECG signals, identifies the type of ECG rhythm, and the microprocessor judges whether electric shock is possible Defibrillation, if it is, the microprocessor controls the external defibrillation module to automatically deliver electric shocks; during the entire analysis and electric shock process, continuous chest compressions are performed simultaneously with the ECG signal analysis before defibrillation, and there is no need to pause the chest before defibrillation. External compression; the chest compression module and assisted breathing module implement uninterrupted chest compression and assisted ventilation. Using this device, emergency personnel can realize one-key operation of cardiopulmonary resuscitation, which will greatly simplify the difficulty of rescue and improve the survival rate of patients with cardiac arrest.

Description

technical field [0001] The invention relates to the field of first aid devices, in particular to an integrated first aid device for sudden cardiac arrest. Background technique [0002] Sudden cardiac arrest causes nearly one million deaths in our country every year, most of which occur outside the hospital. Cardiopulmonary resuscitation is the most effective treatment for patients with sudden cardiac arrest, mainly including three main links: chest compressions, artificial ventilation and electrical defibrillation. According to the requirements of the 2015 cardiopulmonary resuscitation guidelines, for patients with cardiac arrest, the frequency of chest compressions should be maintained at 100-120 times / min, the depth should be 5-6 cm, and 2 artificial ventilations should be given for every 30 chest compressions. ; When ventricular fibrillation occurs in the ECG signal, the electrical defibrillation is implemented in time. [0003] In the current out-of-hospital first aid,...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides an integrated first aid device for sudden cardiac arrest. The present invention overcomes the disadvantages of traditional cardiopulmonary resuscitation, such as high physical exertion, compression and defibrillation cannot be performed at the same time, and comprehensively utilizes physiological signals for real-time electric shock defibrillation, chest compressions, and assisted breathing automation. , integrated technology, design the automatic control program of cardiopulmonary resuscitation, develop the integrated device for cardiac arrest first aid, realize the one-key operation of the first aid process for patients with cardiac arrest, and the rescuers can directly use the device to provide first aid to patients according to the voice prompts, No human intervention is required during the process, see the description below for details:
