摘要

我们开发了一种带有流体动力轴承的便携式轴向流动聚合物桥泵，可用于桥与桥之间。该泵制造成本低廉，可一次性使用。其重量为 185 克，经验证，在静音操作的情况下，使用寿命为 3 个月。在流量为 2 升/分钟的部分循环辅助中，验证了低于 9000 转/分钟的转速下溶血的临床极限，在此转速下产生的压力为 100 mmHg。在抗血栓形成测试中，泵稳定运行 6 小时，没有血栓形成。

Axial-flow polymer bridge pump with hydrodynamic bearings

A portable axial-flow polymer bridge pump with hydrodynamic bearings has been developed for bridge-to-bridge use. The pump is inexpensive to manufacture and disposable. It weighs 185 g and was verified to have a lifetime of 3 months with silent operation. For partial circulatory assist at a flow rate of 2 L/min, the clinical limit of hemolysis was verified for a rotational speed below 9000 rpm, at which a pressure of 100 mmHg was generated. In an anti-thrombogenic test, the pump stably operated for 6 h without thrombus formation.

期刊介绍： The aim of the Journal of Artificial Organs is to introduce to colleagues worldwide a broad spectrum of important new achievements in the field of artificial organs, ranging from fundamental research to clinical applications. The scope of the Journal of Artificial Organs encompasses but is not restricted to blood purification, cardiovascular intervention, biomaterials, and artificial metabolic organs. Additionally, the journal will cover technical and industrial innovations. Membership in the Japanese Society for Artificial Organs is not a prerequisite for submission.
