    摘要: Catheter (1), comprising a first proximal cannula (3) and a second proximal cannula (3'), for connection to blood lines of machines for haemodialysis or similar, respectively affected by a first lumen (4) and by a second lumen (4') for the passage of blood and medical fluids, and pressurised release means (5,5';5) arranged in communication with said first lumen (4) and/or said second lumen (4') for the controlled dispensing of an anti-coagulant fluid in the periods between one treatment and another, so as to prevent the formation of occlusions in the catheter (1), the pressurised release means (5,5';5) comprising an elastomeric pump (6) contained inside a rigid casing (8), said casing (8) being able to be removably associated, at a first opening (9a) for dispensing the anti-coagulant fluid, with said first cannula (3) and/or with said second cannula (3') through a first quick connection element (3a) and/or a second quick connection element (3b). The casing (8) comprises a second opening (10a) for filling said elastomeric pump (6) with anti-coagulant fluid, at which there is a respective quick-fastening closing cap (10c).
