An infusion connector. The outer surface and the outer edge of the infusion connector are a body (1) of a non-sharp structure. An infusion puncture device (16) of the infusion connector does not protrude out of the body (1), so that a nursing staff is prevented from being exposed to a puncture environment having sharp objects when the nursing staff performs infusion operations. The infusion puncture device (16) having a flow guide groove (118) communicates with a liquid discharge opening of an external infusion container, so that a very small quantity of particles or chips are generated, and harm to a human body due to entry of the particles or the chips to the infusion container and mixture of the particles or the chip with a liquid medicine is reduced. By arranging threads, a fastening structure and other forms of connection structures, the infusion connector is fixedly connected to the external infusion container, and more infusion accessory assemblies can be carried, so that a nursing staff can select more infusion accessory assemblies that are more suitable for satisfying demands in disease condition. By arranging a blocking device (15), the germ-free condition in an infusion tube is maintained, and higher infusion safety guarantee can be provided to a patient.La présente invention concerne un raccord de perfusion. La surface extérieure et le bord extérieur du raccord de perfusion sont un corps (1) fait dune structure arrondie. Un dispositif de ponction de perfusion (16) du raccord de perfusion ne fait pas saillie hors du corps (1), de sorte quun personnel soignant évite dêtre exposé à un environnement de ponction présentant des objets pointus lorsque le personnel soignant exécute des opérations de perfusion. Le dispositif de ponction de perfusion (16) ayant une rainure de guidage découlement (118) communique avec une ouverture de déversement de liquide dun récipient externe de perfusion, de sorte quune très petite quantité de particules ou déclats soit générée
