摘要： A blood access device including a fluid conduit configured to convey a flow of fluid to a target vessel, a second lever element pivotally and resiliently connected to a first lever element such that it may move from a first position to a second position. A biasing force is exerted on the second lever element for moving it from the first position to the second position, and a blocking member may be activated by the second lever element, such that a flow of fluid is decreased when the second lever element is moved from the first position to the second position. The lever elements are configured to be fixed to the target vessel when the second lever element is in the first position, and the second lever element moves to the second position and activates the blocking member if the fixation is at least partially lost.

摘要： It is disclosed a circuit for extracorporeal blood treatment in which a flow-inverting device is interposed between a blood treatment unit and a blood pump placed on an artery branch connected with a vascular access of a patient. The flow-inverting device allows the blood flow within the filtering unit to be kept unchanged even following an inverted circulation in the patient-side artery and vein branches controlled by the blood pump.

Flow measurement device which determines at least one blood flow parameter reflecting an average flow in relation to the blood treatment unit during a well-defined period of operation of the apparatus, for example while completing one operation cycle. The at least one blood flow parameter is determined based on a difference between (i) a first amount of fresh blood treatment fluid received into the blood treatment unit, and (ii) a second amount of used blood treatment fluid emitted from the blood treatment unit during another well-defined period.
