| description | To provide a blood purification device capable of coping with a change in a detection value of a first detection part smoothly.SOLUTION: A blood purification device for purifying a patient's blood by circulating the blood extracorporeally through a dialyzer 3 and a blood circuit includes: a blood pump 4 for sending blood in the blood circuit; a piping part having a dialysis fluid introduction line L1 for introducing dialysis fluid to the dialyzer 3 and a drainage discharge line L2 for discharging drainage from the dialyzer 3; a first detection part disposed at a predetermined detection position in the blood circuit for detecting a flow rate or a pressure of the fluid; a second detection part for detecting a flow rate or a pressure either of the fluid on a downstream side of the detection position in the blood circuit or of the dialysis fluid in the piping part; and a determination part 23 for determining propriety of the detection value of the first detection part on the basis of a change in the pressure detected by the second detection part when the detection value of the first detection part reaches a predetermined threshold.SELECTED DRAWING: Figure 1
【課題】第１の検出部の検出値が変化した際の対応を円滑に行わせることができる血液浄化装置を提供する。【解決手段】ダイアライザ３及び血液回路を通じて患者の血液を体外循環させ、当該血液を浄化する血液浄化装置であって、血液回路の血液を送液させる血液ポンプ４と、ダイアライザ３に透析液を導入する透析液導入ラインＬ１、及びダイアライザ３から排液を排出する排液排出ラインＬ２を有する配管部と、血液回路における所定の検出位置に配設され、液体の流量又は圧力を検出する第１の検出部と、血液回路における検出位置より下流側の液体、及び配管部における透析液の何れかの流量又は圧力を検出する第２の検出部と、第１の検出部の検出値が所定の閾値に達するとき、第２の検出部で検出された圧力の変化に基づいて第１の検出部の検出値の適否を判断する判断部２３とを具備したものである。【選択図】図１ |
