Title (EN) PUMP DEVICE
(FR) DISPOSITIF DE POMPE
(JA) ポンプ装置
Abstract:
(EN) This pump device (10) comprises: a housing (30) including a blood inflow port (38) through which blood flows in, and having a fixed-side repulsive magnet (44) arranged in an annular manner; and an impeller (14) rotatably housed inside the housing (30), and having a movable-side repulsive magnet (56) arranged in an annular manner. The fixed-side repulsive magnet (44) is arranged in a position offset toward the blood inflow port (38) side relative to the movable-side repulsive magnet (56). In the fixed-side repulsive magnet (44) and the movable-side repulsive magnet (56), a fixed-side repulsive surface (44a) and a movable-side repulsive surface (56a) adjacent to one another have the same polarity.
(FR) Ce dispositif de pompe (10) comprend : un boîtier (30) comprenant un orifice d'entrée de sang (38) à travers lequel s'écoule le sang, et ayant un aimant répulsif côté fixe (44) disposé de manière annulaire; et une roue (14) logée rotative à l'intérieur du boîtier (30), et ayant un aimant répulsif côté mobile (56) agencé de manière annulaire. L'aimant répulsif côté fixe (44) est disposé dans une position décalée vers le côté d'orifice d'entrée de sang (38) par rapport à l'aimant répulsif côté mobile (56). Dans l'aimant répulsif côté fixe (44) et l'aimant répulsif côté mobile (56), une surface répulsive côté fixe (44a) et une surface répulsive côté mobile (56a) adjacentes l'une à l'autre ont la même polarité.
(JA) ポンプ装置(10)は、血液を流入させる血液流入ポート(38)を備えると共に、固定側反発磁石(44)を環状に配置したハウジング(30)と、ハウジング(30)内に回転自在に収容され、可動側反発磁石(56)を環状に配置したインペラ(14)と、を備える。固定側反発磁石(44)は、可動側反発磁石(56)に対して血液流入ポート(38)側にオフセットされた位置に配置される。固定側反発磁石(44)と可動側反発磁石(56)は、相互に近接し合う固定側反発面(44a)と可動側反発面(56a)の極性が同一である。
