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) having an extracorporeal blood circuit (2), in which an electric current is made to flow along a closed-loop path (P1) of an electrical circuit (37) formed by an electrical line (21, 22, 23) external to the extracorporeal circuit (2), a portion of extracorporeal circuit (2) directly connected to the venous needle (13), and the patient (P); a signal correlated with the electric current along the electrical line (21, 22, 23) is detected; and the signal is compared with a threshold value by means of a control unit (15).
La présente invention concerne la détection de sortie d'aiguille (13) de la veine d'un patient (P) pendant un traitement extracorporel du sang dans un dialyseur (1). Ce dernier comporte une circulation sanguine extracorporelle (2) dans lequel on fait circuler un courant électrique selon un trajet en boucle (P1) par un circuit électrique (37) réunissant une ligne électrique (21, 22, 23) extérieure à la circulation extracorporelle (2), une partie de la circulation extracorporelle (2) en contact direct avec l'aiguille de la veine (13), et le patient (P). On détecte un signal en corrélation avec le courant électrique circulant dans la ligne électrique (21, 22, 23), et un contrôleur (15) vient le comparer à une valeur de seuil.
