| 摘 要： | 为了与作者所承担的国家自然科学基金项目“以膜肺为基础的脑保护机制的研究”配套，作者设计了以８０３１芯片为控制核心，用变频器控制特制的同步电机，以压力、压差、温度传感器检测心脑肺复苏装置的体外循环状况，并将信息反馈给控制系统。为适应人体内血液流动情况，设计了恒速与脉动两种模式来驱动血泵。对血泵的调速及控制的测试验证这两种调速模式均能有效地实现调速功能。压力、温度和流量测量的精度远大于八位Ａ／Ｄ转换顺

| Abstract: | A novel idea in developing cardiopulmonary cerebral resuscition(CPCR) device has been developed, using a combination of membrane artificial lung(oxygenator), mild hypothermia, and centrifugal blood pump technologies. A control system for the CPCR has been introduced, using converter control and sensor monitor, with 8031 chips as the controller. Pressure, flow rate and temperature monitors were installed in the system. Two modes of blood pump regulation have been adopted, i.e. continous flow and pulsatile flow. The in vitro evaluation tests showed that the two modes were reasonable and feasible. |
