目的研制动物心肺时相撞击自动控制系统 ,以进行动物心或肺不同活动时相的撞击伤研究。方法控制系统由信号采集装置、触发器、电磁铁和微计算机组成 ,与摆锤式撞击台配套使用。由计算机键盘输入摆锤下落时间、K值及撞击指令 ,撞击程序运行。以呼吸波峰或心电R波峰作为撞击触发的参照点 ,计算出触发延时量 ,确定触发点 ,实施触发 ,完成预定的心或肺活动时相撞击。结果能准确地进行动物心肺不同活动时相的撞击。结论本控制系统可用于各种动物撞击装置的心肺时相撞击控制
Objective To develop an automatic control system of animal heart-lung phase-to-phase collision to study the impact injury of different phase of heart or lung activity in animals. Method The control system consists of signal acquisition device, trigger, electromagnet and microcomputer, and is used together with pendulum impact stage. Enter the pendulum drop time by computer keyboard, K value and impact command, impact program operation. Take the peak of respiratory wave or R wave of ECG as the reference point of impact trigger, calculate the trigger delay amount, determine the trigger point, implement the trigger, and complete the scheduled heart or lung activity phase impact. Results can accurately carry out the impact of different activities of animal heart and lung phase. Conclusion The control system can be used for CPR control of various animal impact devices
