A new type of motor-driven total artificial heart system with a moving-actuator mechanism has been developed. The prototype system consists of a brushless dc motor inside of a rolling-cylinder, two arc-shaped pusher-plates and two polyurethane sacs. The moving-actuator type electromechanical pump has structural advantages of small size and light weight, as compared to other reported motor-driven pumps with fixed-actuator mechanisms. The results of the mock circulation tests are reported in this paper with a cardiac output of 9 L/min at an aortic pressure of 120 mmHg and a heart rate of 120 bpm. The fulfillment of the basic control requirements of the artificial heart was also confirmed, i.e., preload sensitive and afterload insensitive cardiac output response and balanced right and left ventricular outputs.
一种新型的带有移动驱动机构的电动全人工心脏系统已被开发出来。该原型系统由一个位于滚动圆柱体内的无刷直流电机、两个弧形推板和两个聚氨酯囊组成。与其他报道的具有固定驱动机构的电动泵相比，移动驱动型机电泵具有体积小、重量轻的结构优势。本文报道了模拟循环测试结果，在心输出量为9升/分钟、主动脉压力为120毫米汞柱、心率为120次/分钟的情况下，人工心脏的基本控制要求也得到了证实，即前负荷敏感和后负荷不敏感的心输出量响应以及左右心室输出平衡。
