New proposal of safely long-term drive for Pediatric cardiopulmonarysupport system

为保证小儿心肺支持系统的安全性，应建立离心泵在低流量和高耐用性条件下的安全驱动方法。我们通过动物实验来评估小儿CPS的新方法。暖风吹向人工肺气体出口，提高了人工肺的耐用性。吹温气对人工肺中空纤维膜的亲水性有抑制作用。人工肺与血泵之间的分流回路在低流量下稳定泵速，提高气体交换能力，抑制血栓形成，减少血栓形成。

For safe Pediatric cardiopulmonary support (CPS), we shouldestablish the secure drive methods of centrifugal pump at low flow and high durabilityof the CPS system. We performed animal experiments to assess our new methods forpediatric CPS. Warm wind blew to artificial lung gas outlet due to improve durabilityof the artificial lung. Blowing warm gas showed the prevention of hydrophilization ofhollow fiber membrane in the artificial lung. The Shunt circuit between artificial lungand blood pump showed the effectiveness to stabilize the pump speed at low flow rate,improve the gas exchange capacity , suppressive, and reduce the thrombus formation.
