METHOD AND DEVICE FOR DETECTING THE DETACHMENT OF THE VENOUS NEEDLE FROM A PATIENT DURING DIALYSIS

摘要

A method of detecting the detachment of the venous needle (13) from a patient (P) during an extracorporal blood treatment in a dialysis machine (1) having an extracorporal blood circuit (2) provided with an arterial branch (8) and a venous branch (10) comprises the measurement of the arterial presure (Pa) in the arterial branch (8) and the venous pressure (PV) in the venous branch (10), and the determination of whether or not decreases of the arterial pressures (Pa) and pressures (PV) are occuring during the dialysis treatment in normal conditions.
