The technical aspects of artificialheart design for experiments on calves are presented in this paper. The object of the design was to verify the basic anatomic and hemodynamic criteria for the design of more perfect cardiac prostheses. Each of the ventricles has a 100-ml stroke volume and is dismountable. Rigid parts are made of polymethylmethacrylate. The inlet valve has the shape of a flap. The outlet valve has two polyurethane reinforcing leaves. The diaphragm is also made of polyurethane. During tests using artificial circulation, a maximum cardiac output of 14.6 L/min was achieved. Typical sensitivity of flow on the atrial pressure is 0.3 L/min/torr at a frequency of 90 pulses per minute.
本文介绍了用于小牛实验的人工心脏设计的技术方面。设计目的是验证更完善的心脏假体设计的基本解剖学和血液动力学标准。每个心室的搏出量为100毫升，且可拆卸。刚性部件由聚甲基丙烯酸甲酯制成。入口阀为瓣状。出口阀有两片聚氨酯加强叶。隔膜也由聚氨酯制成。在使用人工循环的测试中，最大心输出量达到14.6升/分钟。在每分钟90次搏动的频率下，流量对心房压力的典型敏感度为0.3升/分钟/托。
