Title
(EN) BLOOD PURIFICATION DEVICE AND PRIMING METHOD THEREFOR
(FR) DISPOSITIF DE PURIFICATION DU SANG ET PROCÉDÉ D'AMORÇAGE ASSOCIÉ
(JA) 血液浄化装置及びそのプライミング方法
Abstract
(EN) Disclosed is a blood purification device that is capable of transitioning from priming to blood purification therapy while a fluid replacement line is still connected and is capable of improving workability during the transition from priming to blood purification therapy. Also disclosed is a priming method therefor. During priming, the other end of the fluid replacement line (L3) is connected at the same location as the connected location of said fluid replacement line (L3), which is determined in accordance with whether either pre-fluid replacement in which rehydrating fluid is supplied to an arterial side air trap chamber (5) or post-fluid replacement in which the rehydrating fluid is supplied to a venous side air trap chamber (6) will be performed in the blood purification therapy process, and the end of an arterial side blood circuit (2) and the end of a venous side blood circuit (3) are connected together to communicate fluid. In addition, a blood pump (4) is driven in normal rotation or in reverse rotation while the rehydrating fluid is supplied from said fluid replacement line (L3), thereby discharging the rehydrating fluid from an overflow line (6a).
(FR) La présente invention concerne un dispositif de purification du sang capable d'assurer la transition entre un amorçage et un traitement de purification du sang, alors qu'un tuyau de substitution de liquide est encore connecté, et qui est capable de faciliter la transition entre l'amorçage et le traitement de purification du sang. L'invention concerne également un procédé d'amorçage associé. Durant l'amorçage, l'autre extrémité du tuyau de substitution de liquide (L3) est raccordée à l'emplacement correspondant à l'emplacement de raccordement dudit tuyau de substitution de liquide (L3), qui est déterminé selon qu'est pratiquée, dans le cadre du processus thérapeutique de purification du sang, soit une substitution préalable de liquide au cours de laquelle le liquide de réhydratation est amené jusqu'à une chambre faisant siphon (5) du côté artériel, soit une substitution a posteriori du liquide au cours de laquelle le liquide de réhydratation est amené jusqu'à une chambre faisant siphon (6) du côté veineux. L'extrémité d'un circuit sanguin côté artériel (2) et l'extrémité d'un circuit sanguin côté veineux (3) sont reliées entre elles pour qu'il y ait communication de liquide. En outre, une pompe sanguine (4) est activée dans le sens normal de rotation ou dans le sens inverse de rotation pendant que le liquide de réhydratation est amené depuis le tuyau de substitution de liquide (L3), ce qui permet l'évacuation du liquide de réhydratation par un tuyau de trop-plein (6a).
(JA) 【課題】補液ラインの接続状態を維持した状態にてプライミングから血液浄化治療に移行させることができ、プライミングから血液浄化治療へ移行する際の作業性を向上させることができる血液浄化装置及びそのプライミング方法を提供する。 【解決手段】プライミング時、血液浄化治療過程で動脈側エアトラップチャンバ5に補充液を供給する前補液又は静脈側エアトラップチャンバ6に補充液を供給する後補液の何れかが行われるかに応じて決定される補液ラインL3の接続部位と同一の部位に当該補液ラインL3の他端が接続されるとともに、動脈側血液回路2の先端と静脈側血液回路3の先端とが接続して連通した状態とされ、且つ、当該補液ラインL3から補充液を供給させつつ血液ポンプ4を正転駆動又は逆転駆動させ、オーバーフローライン6aから補充液を排出させるものである。
