The invention relates to a transfusion connector. The transfusion connector is provided with a body with an outer surface being a blunt structure, so that the nursing personnel can be prevented from being exposed in a sharp transfusion puncture environment when in transfusion operation. 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 an 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 a movable sealing apparatus, the blood can be prevented from flowing back to the transfusion pipe and the air in a transfusion apparatus can be prevented from entering the human body since the transfusion cannot be handled in time when the transfusion is ended, and the transfusion safety is ensured. By arranging an obstruction apparatus, a higher transfusion safety guarantee can be provided for a patient. The transfusion connector is applied to the field of medical equipment.
