空气驱动式左心辅助泵血泵部分与气室部分之间的密封方法 ,一直是泵研制者关注的问题。广东省心血管病研究所研制的左心辅助泵 (罗叶泵 )由原来设计的螺栓密封改进为树脂螺纹套密封 ,泵体积在有效容积不变的情况下 ,外尺寸大大缩小 ,密封性能也大幅度提高。改进后的左心辅助泵? The sealing method between the blood-driven part of the air-driven left heart assisted pump and the air chamber part has always been a concern of the pump developer. The left heart auxiliary pump (Luoye pump) developed by the Guangdong Institute of Cardiovascular Disease has been improved from the original designed bolt seal to the resin threaded sleeve seal. With the pump volume constant under the same effective volume, the external dimensions are greatly reduced, and the sealing performance is also reduced. substantial improvement.
