Abstract
(EN)
Provided are a hemodialysis device and a supplemental liquid line connection state detection method that can accurately detect the attachment state of a supplemental liquid clamp for opening-closing a supplemental liquid line. The hemodialysis device 100 comprises a blood circuit 110, a dialysate circuit 130, a supplemental liquid line 140, a supplemental liquid pump 140a, a supplemental liquid clamp 140b, a pressure sensor 140c measuring the liquid pressure in the supplemental liquid line 140, a control unit 161, and a determination unit 162, wherein the control unit 161 activates the supplemental liquid pump 140a, causing the liquid pressure of the supplemental liquid line 140 to rise, and the determination unit 162 determines that the supplemental liquid line 140 is connected correctly if the measured liquid pressure in the supplemental liquid line 140 is at a predetermined value or higher, and determines that the supplemental liquid line 140 is not connected correctly if the measured liquid pressure is smaller than the predetermined value.

L'invention concerne un dispositif d'hémodialyse et un procédé de détection d'état de raccordement de ligne de liquide supplémentaire qui peut détecter avec précision l'état de fixation d'une pince à liquide supplémentaire pour ouvrir et fermer une ligne de liquide supplémentaire. Le dispositif d'hémodialyse 100 comprend un circuit sanguin 110, un circuit de dialysat 130, une ligne de liquide supplémentaire 140, une pompe à liquide supplémentaire 140a, une pince à liquide supplémentaire 140b, un capteur de pression 140c mesurant la pression de liquide dans la ligne de liquide supplémentaire 140, une unité de commande 161 et une unité de détermination 162, l'unité de commande 161 activant la pompe à liquide supplémentaire 140a, provoquant l'élévation de la pression de liquide de la ligne de liquide supplémentaire 140 et l'unité de détermination 162 déterminant que la ligne de liquide 140 supplémentaire est reliée correctement si la pression de liquide mesurée dans la ligne de liquide supplémentaire 140 est à une valeur prédéterminée ou plus et déterminant que la ligne de liquide supplémentaire 140 n'est pas raccordée correctement si la pression de liquide mesurée est inférieure à la valeur prédéterminée.
(JA)
補充液ラインを開閉する補充液クランプの装着状態を精度よく検出できる血液透析装置及び補充液ラインの接続状態検出方法を提供する。血液透析装置100は、血液回路110、透析液回路130、補充液ライン140、補充液ポンプ140a、補充液クランプ140b、補充液ライン140の液圧を測定する圧力センサ140c、制御部161及び判定部162、を備え、制御部161は、補充液ポンプ140aを作動させて補充液ライン140の液圧を上昇させ、判定部162は、補充液ライン140の測定液圧が所定の値以上である場合に、補充液ライン140が正しく接続されていると判定し、測定液圧が所定の値より小さい場合に、補充液ライン140が正しく接続されていないと判定する。
