An infusion connector. By arranging a body (1) whose outer surface and outer edge are non-sharp structures and enabling an infusion puncture device (16) not to protrude out of the body (1), a nursing staff is prevented from being exposed to an infusion puncture environment having sharp objects when the nursing staff performs infusion operations. The infusion puncture device (16) is also provided with a hollow channel (119), the infusion puncture device (16) is provided with a connector liquid inlet (11), an connector liquid outlet (12) communicates with a liquid storage chamber of an external infusion container by means of the connector liquid inlet (11), a very small quantity of particles or chips are generated, and harm of the particles to a human body is reduced. By arranging threads, a fastening structure and other forms of fixing devices (2), 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 liquid dropping device (111) and a hollow chamber (110), the infusion connector can serve as a dropping hopper at the same time. 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.Dispositif de raccordement pour perfusion permettant déviter que le personnel soignant soit exposé, lors dune perfusion, à un environnement où il risque de se piquer avec les objets perçants quil manipule étant donné que la surface externe dagencement et que le bord extérieur tiennent lieu de corps (1) dune structure non élastique et que le corps (1) ne fait pas saillie au niveau dun dispositif de ponction pour perfusion.
