Title
(EN) HEMODIALYSIS APPARATUS AND CONNECTION STATE DETECTION METHOD OF REPLENISHMENT LIQUID LINE
(JA) 血液透析装置及び補充液ラインの接続状態検出方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a hemodialysis apparatus and a connection state detection method of a replenishment liquid line that can accurately detect a mounting state of a replenishment liquid clamp for opening/closing the replenishment liquid line.

SOLUTION: A hemodialysis apparatus 100 includes a blood circuit 110, a dialysis liquid circuit 130, a replenishment liquid line 140, a replenishment liquid pump 140a, a replenishment liquid clamp 140b, a pressure sensor 140c for measuring liquid pressure of the replenishment liquid line 140, a control unit 161, and a determination unit 162. The control unit 161 actuates the replenishment liquid pump 140a and increases the liquid pressure of the replenishment liquid line 140. The determination unit 162 determines that the replenishment liquid line 140 is correctly connected when the measured liquid pressure of the replenishment liquid line 140 is a predetermined value or more, and determines that the replenishment liquid line 140 is not correctly connected when the measured liquid pressure is less than the predetermined value.

【課題】本発明は、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ことを目的とする。
【解決手段】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。
