针对体外反搏装置充排气时间准确性及自动化程度差的缺陷,提出了一种体外反搏装置充排气时间自动优化方法。开发了颞脉波的采集和处理电路,并根据采集的颞脉波在反搏前后的特征点,设计了颞脉波特征点的搜索算法。根据搜索的特征点,给出了体外反搏装置充排气时间自动调节算法,实现了体外反搏装置充排气时间自动调节,获得了最佳的反搏效果,大大提高了体外反搏装置的自动性、安全性和有效性,具有广阔的市场应用前景和参考价值。

Aimed at the shortcomings of accuracy and poor automation of the external counterpulsation inflation/deflation timing, an automatic optimization method of the external counterpulsation device inflation/deflation timing is presented. The temporal pulse wave acquisition and processing circuit is designed, and according to the temporal pulse acquisition in counterpulsation before and after the feature points, the search method of the temporal pulse potter character point is designed. According to the features of search points, the design of external counterpulsation device inflation/deflation timing automatic adjustment algorithm realizes the automatic adjustment of the external counterpulsation device inflation/deflation timing and optimal counterpulsation effect, which greatly improves the automatic, safety and effectiveness of the device, and has a good reference value and application prospects.
