The utility model relates to a single needle double path transfusion device, and the outside of the hollow needle head is tightly sleeved with a needle head sleeve, and the front end of the needle head is in cone shape, and the cone-shaped part is provided with small holes. The back end of the needle head is in Y shape respectively connected with a path and b path. The a path is connected with the needle head and communicated with needle head inner hole, and the b path is communicated with the needle head sleeve. The utility model solves the disadvantage that: when one patient needs to be transfused synchronously or use multi medicine in the clinical work, the transfusion path is needed to be rebuilt. The utility model has the advantages that: one needle head can built two different transfusion path, and the two transfusion paths can respectively and synchronously transfuses different liquid to the body to meet requirements of different speed and using multi drugs, which can avoid the interaction of the drugs and can greatly develop the treatment effect of the drugs, thereby reducing the damaging to the patient blood vessel and the pain of the patient.
