The invention relates to a transfusion connector. The transfusion connector is provided with a body with an outer surface and an outer edge being a non-sharp structure, and a transfusion puncture outfit is not protruded out of the body, so that the nursing personnel can be prevented from being exposed in a sharp transfusion puncture environment when in transfusion operation. A puncture outfit with a guide groove is communicated with a liquid outlet of an external transfusion container, and a connector liquid outlet is communicated with a liquid storage cavity of an external transfusion container by virtue of the connector liquid inlet, and few micro-particles or chippings are produced, so that the harm of the micro-particles on the human body can be reduced. By arranging a connection structure in a form of threads, a buckle structure and the like, a fixed connection effect between the transfusion connector and the external transfusion container can carry more transfusion accessory components, so that the medical personnel can select the transfusion accessory component better meeting the disease requirement. The transfusion connector is matched with an opening on the external transfusion container, so that a purpose of rapid transfusion can be achieved. By arranging an obstruction apparatus, a sterile state inside the transfusion pipeline can be maintained, and a higher transfusion safety guarantee can be provided for a patient. The transfusion connector is applied to the field of medical equipment.
