Method of monitoring the functionality of a cutting element of flow and flow stop system for an extracorporeal fluid circuit.

摘要

Method for monitoring the functionality of an element for cutting the flow of a fluid through an extracorporeal circuit (2), said circuit (2) at least one length of deformable tubing (10) which acts at least one element flow cut (9) having at least one movable part (11) actuable to switch between an open state in which it allows the passage of fluid, and at least one closed state, in the which it prevents the flow of fluid through said pipe section (10), said method comprising the following steps: - moving the movable portion (11) of the cutting element (9) in order to pass from said open state to said state closure; - associating at least one dynamic parameter with a motion of said movable part (11); - determining a value of said dynamic parameter is at least one with respect to said movable portion (11) at least during said movement; - verify that the value adopted by said dynamic parameter meets predetermined criteria acceptability.
