当前除颤器已广泛用于临床,但心脏除颤复律率仍无可靠的规律性,这样给医务工作者带来困难,给心脏除颤病人带来莫大的危害。为了研究除颤电流与心脏复律率间的规律性,去除心脏除颤工作中的盲目性,我们制作了一台用普通电表显示除颤放电峰峰值的测定器,它具有电路简单、重复性好、存储与记忆时间长、使用安全方便等特点。临床应用已见成效,现继续在临床试用,检验效果。理论分析为了找出除颤电流峰值与各种电量间的关系,必须进行定量分析。分析中C(放电电容18μf/TKV)和L(阻尼电感0.2H)的取值来源于全国使用最广的XQQ-1型除颤器。一、除颤器中储能电容C(18μf)的端电
The current defibrillator has been widely used in clinical practice, but the defibrillation cardioversion rate is still no reliable regularity, so that medical staff to bring difficulties to patients with cardiac defibrillation great harm. In order to study the regularity between defibrillating current and cardioversion rate and to eliminate the blindness in defibrillation work, we made an analyzer that displays the peak-to-peak defibrillation discharge with an ordinary electric meter, which has the advantages of simple circuit and repeatability Good, storage and memory of a long time, the use of safe and convenient features. Clinical results have been achieved, is now continuing in clinical trials, test results. Theoretical Analysis In order to find out the relationship between the peak value of defibrillation current and various power levels, we must conduct quantitative analysis. Analysis of C (discharge capacitance 18μf / TKV) and L (damping inductance 0.2H) value from the country’s most widely used XQQ-1-type defibrillator. First, the defibrillator storage capacitor C (18μf) the end of electricity
