伯尔尼研究人员设计使用心脏的液压动力运行医疗器械

Lucas在IEEE(电机及电子学工程师联合会)谱网站上发表的文章中表示,瑞士伯尔尼大学和伯尔尼应用科学院的研究人员开发出可以放在动脉内的小型涡轮机。

这种涡轮机可以通心脏自然产生的液压动力设计, 为诸如心脏起搏器等医疗器械供电。这将无需使用电池或通过手术更换电池,也会使设备体积更小。

生物医学工程师Alois Pfenniger领导该项研究,并在瑞士卢塞恩举办的医疗和生物微技术国际会议上介绍了最近的实验结果。试验中,涡轮机在模拟胸廓内动脉中进行测试。根据该文章,最有效的涡轮机据说生成出大约800微瓦的功率,而一个起搏器大约需要10微瓦的功率。

由于涡轮机在动脉中产生湍流,容易造成血液凝块。研究人员正努力找到解决办法。

除了心脏起搏器,涡轮机还可以驱动如血压传感器、药物输送泵或神经刺激器等医疗器械。欧洲医疗设计技术主编Norbert Sparrow在六月期的“编者案”中讨论了此种自充电的心脏起搏器,文章讨论了有关Heart-Beat Scavenger (HBS) 联合机构。此联合机构由法国格勒诺布尔的研发机构——Leti牵头,旨在开发由心脏运动产生的能量驱动的心脏起搏器。
