摘要

A method of sensing the detachment of the venous needle (13) from a patient(P) during an extracorporeal blood treatment in a dialysis machine (1) havingan extracorporeal blood circuit (2), in which an electric current is made toflow along a closed-loop path (P1) of an electrical circuit (37) formed by anelectrical line (21, 22, 23) external to the extracorporeal circuit (2), aportion of extracorporeal circuit (2) directly connected to the venous needle(13), and the patient (P); a signal correlated with the electric current alongthe electrical line (21, 22, 23) is detected; and the signal is compared witha threshold value by means of a control unit (15).
