PROBLEM TO BE SOLVED: To provide a fluid conveyance monitoring system to minimize the risk of haemolysis.SOLUTION: The resent invention relates to a method for monitoring fluid conveyance in an extracorporeal blood treatment device, which method allows fluid to be conveyed by a peristaltic pump 2 in a fluid system from a low-pressure side to a high-pressure side in that an elastically deformable fluid line 19 positioned between the low-pressure side and the high-pressure side is deformed in such a way that conveyance volume sections 22, 23 are formed between a support surface and at least two squeeze elements 16, 17 of a rotor 12 rotating opposite the support surface. As for the conveyance volume sections, fluid pressure values in the fluid system are detected that are specific to the conveyance volume sections, and the detected conveyance-volume-specific fluid pressure value of a conveyance cycle n is compared with the detected conveyance-volume-specific fluid pressure value of a previous conveyance cycle n-x in each conveyance volume section.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】溶血リスクを最小化するための、流体運搬モニタリングシステムを提供する。【解決手段】体外血液処置装置中における流体運搬をモニタする方法は、支持面と、支持面とは反対向きに回転するロータ12の少なくとも2つの圧搾要素群16、17との間において、運搬容積区間22、23が形成されるように、低圧側と高圧側の間に位置する弾性変形可能な流路19が変形し、変形のため、流体システムにおける蠕動ポンプ2を用いて、流体が、該低圧側から該高圧側へ運搬されるものであり、運搬容積区間に関し、流体システムにおける運搬容積区間に特有な血圧値が検出され、運搬サイクルnの運搬容積に特有な検出済み血圧値が、先行する運搬サイクルn-xの運搬容積に特有な検出済み血圧値と比較される。【選択図】図1
