Abstract

The invention relates to an audio power amplifier circuit applied to a defibrillator, and the circuit comprises a voice module which is used for outputting a voice signal; an audio power amplification module, which is electrically connected with the voice module and is used for acquiring the voice signal and performing power amplification on the voice signal and obtaining an audio power amplification output signal, and comprises an audio power amplification chip which is provided with an audio signal input end and an audio signal output end, the audio signal input end being electrically connected with the voice module. According to the audio power amplification circuit applied to the defibrillator, the audio signal is amplified through the audio power amplification chip of the audio power amplification module, and the problem that the use effect of an automatic defibrillator is not ideal due to the fact that the voice prompt tone is small is solved.

Description

technical field [0001] The invention relates to the field of circuits, in particular to an audio power amplifier circuit applied to a defibrillator and the defibrillator. Background technique [0002] An automatic external defibrillator (AED) is the only and effective rescue device for patients with sudden cardiac death. With the rapid improvement of my country's economic development and people's living standards, there are more than 545,000 sudden cardiac death patients in my country every year. From a medical point of view, when sudden cardiac death occurs, defibrillation must be performed within 12 minutes, otherwise, the survival rate of patients with sudden cardiac death is less than 2%. In today's busy world, almost no country or city can guarantee that an ambulance will arrive at the scene of the accident within 12 minutes to provide timely rescue for patients with sudden cardiac death. Therefore, in most developed countries, AEDs have entered families or are widely...
