Abstract

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.

带流体动力轴承的轴流式聚合物桥泵

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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
