External cardiac massage rhythm prompting device and method thereof

Abstract

The invention provides a closed cardiac compression rhythm prompting device applicable to an automatic in-vitro defibrillator and a method thereof. The device comprises an ARM / DSP controller, a rhythm prompting module and a detection module, wherein a sound generation circuit, a light generation circuit and an image generation circuit in the rhythm prompting module are controlled by the ARM / DSP controller respectively; in the detection module, an excitation pulse generation and drive circuit, an electrocardioelectrode, a preposed difference pre-magnifying circuit, a diode detection and regulation circuit, a filter circuit, gain adjustment and potential transition and an A / D converting circuit are electrically connected in sequence; the A / D converting circuit is electrically connected withthe ARM / DSP controller; and the excitation pulse generation and drive circuit and the gain adjustment and potential transition are controlled by the ARM / DSP controller. The device and the method givean operator correct guidance through three prompting modes, namely sound, light and image, and give a specific prompt to incorrect compressing operation by detecting actual compressing rhythm and strength so as to prompt the operator to correct the incorrect operation in time.

Description

technical field [0001] The present invention relates to an external cardiac compression rhythm prompter suitable for automatic external defibrillators and a method thereof to correctly guide the implementation of cardiopulmonary resuscitation first aid measures, and in particular to a monitoring method for chest impedance changes caused by external cardiac compressions Detection belongs to the technical field of medical equipment. Background technique [0002] Most sudden cardiac arrests are caused by ventricular fibrillation (VF), in which the heart stops beating, resulting in insufficient blood flow to the heart, brain and other organs. Failure to terminate ventricular fibrillation in time to allow the heart to resume its own normal rhythm usually results in death. Rapid defibrillation is the only effective means of restoring normal heart rate and preventing death from ventricular fibrillation after cardiac arrest. If defibrillation is performed within 1 minute of cardia...
