Title (EN) IMPELLER AND BLOOD PUMP
(FR) TURBINE ET POMPE À SANG
(JA) インペラ及び血液ポンプ
Abstract:
(EN) An impeller (12) of a blood pump (10) comprises a hub (22) which is driven in rotation, and a plurality of blades (26) each comprising a resilient body extending radially from the hub (22). Each of the plurality of blades (26) is configured in such a way that the radial direction length of each of the plurality of blades (26) changes in accordance with a fluid force during rotation, and each of the plurality of blades (26) has a shape in which the radial direction length increases as the fluid force increases.
(FR) L'invention concerne une turbine (12) d'une pompe à sang (10) qui comprend un moyeu (22) qui est entraîné en rotation, et une pluralité de pales (26) comprenant chacune un corps élastique s'étendant radialement à partir du moyeu (22). Chaque pale de la pluralité de pales (26) est conçue de telle sorte que la longueur dans le sens radial de chaque pale de la pluralité de pales (26) change en fonction d'une force de fluide pendant la rotation, et chaque pale de la pluralité de pales (26) a une forme dont la longueur dans le sens radial augmente lorsque la force de fluide augmente.
(JA) 血液ポンプ(10)のインペラ(12)は、回転駆動されるハブ(22)と、ハブ(22)から放射状に延出した弾性体からなる複数の羽根(26)とを有する。複数の羽根(26)の各々は、回転時に流体力に応じて複数の羽根(26)の各々の径方向長さが変化するように構成されるとともに、流体力が大きくなる程、径方向長さが大きくなる形状を有する。
