    摘要: The apparatus for blood flow control in an extracorporeal circuit comprises: a user interface for setting a desired blood flow value (qbREAL) and a datum relating to the vascular access, a memory for recording a plurality of mathematical relations having mathematical expressions relating to the vascular access organ to be used, and a control unit. The control unit identifies the vascular access, selects, from among the plurality of mathematical relations present in the memory, a relation which corresponds to the vascular access identified, and calculates, as a mathematical function of the set value for the desired flow (qbREAL), a value at which to set the angular velocity of the pump associated to the extracorporeal circuit and/or a theoretical value of the arterial pressure upstream of the pump.

    摘要: An extracorporeal blood treatment apparatus comprises a sensor (10) for emitting a signal indicating a change of hematic volume of an individual (7) subjected to a treatment and a weight loss system for actuating the individual's weight loss. A control unit (20) receives an effective weight value of the individual and a desired weight loss value and from these values determines a desired value of a change in hematic volume at end of treatment. The weight loss system is controlled on a basis of the hematic volume change signal and the desired value of the hematic volume change. The apparatus enables automatic control of a dialysis operation while preventing some complications arising from hypotension.
