本工作是为开发婴儿用的人工心肺装置,特别是对灌流操作困难的早产儿安全实现体外循环的系统而进行的研究。控制系统由三台微型计算机所组成。其中一台用作控制脉动灌流泵,另一台为控制台操作用。而主要的一台微型机用于控制血流和血压。微型计算机通过人工心肺装置而完全控制血流和血压。在开始时人工心肺机自动地从每分钟26毫升/公斤的血流量增加到每分钟80毫升/公斤,并自 This work is intended to develop artificial cardiopulmonary devices for infants, especially those that safely perform cardiopulmonary bypass in premature infants who have difficulty in perfusion. The control system consists of three microcomputers. One of them is used to control the pulsatile perfusion pump and the other to operate the console. The main microchip is used to control blood flow and blood pressure. Microcomputers completely control blood flow and blood pressure through artificial cardiopulmonary devices. At the beginning, the artificial heart-lung machine automatically increased blood flow from 26 ml / kg to 80 ml / kg per minute and from
