Embodiment 1

[0039] A kind of cardiac arrest first aid integrated device, see figure 1 , the device includes: a microprocessor 1 , an external defibrillation module 2 , a chest compression module 3 , a breathing assistance module 4 , and a voice prompt module 5 .

[0040] The whole device is controlled by the microprocessor 1, operates the external defibrillation module 2, the external chest compression module 3, and the assisted breathing module 4 to provide first aid to the patient, and uses the voice prompt module 5 to instruct rescuers. Among them, the patient's physiological signals, pressing, and breathing related reference signals are uploaded to the microprocessor 1 by the integrated sensor in the corresponding module, and the microprocessor 1 analyzes and determines the next step.

[0041] The workflow of the whole device is as follows figure 2 As shown, after the rescuer places the patient in the correct position according to the voice prompt module 5, the first aid process is ...

Embodiment 2

[0050] Below in combination with specific calculation formulas and examples, the microprocessor 1 in Embodiment 1 performs interference noise filtering on ECG signals and the process of ECG rhythm type identification is further introduced, see the following description for details:

[0051] Since the chest compression process will introduce serious noise interference in the ECG, the ECG analysis algorithm cannot accurately classify the ECG rhythm. Therefore, the purpose of the embodiment of the present invention is to filter out the chest compression interference noise in the ECG signal , so that continuous chest compressions and electrocardiographic signal analysis before electrical defibrillation can be implemented simultaneously, without the need to pause chest compressions before implementing electrical defibrillation.

[0052] 1) With 250Hz as the sampling frequency, sample the ECG signal for 10s, with a total of 2500 sampling points;

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,...
