The utility model relates to a disposable transfusion device with photoelectric indication. The utility model has a thin and flexible tube. The upper end of the thin and flexible tube has a tee for a thick needle, the middle section of the thin and flexible tube is connected with a murphy's dropper and a filter, and the lower end of the thin and flexible tube has a needle head. A flow regulator is sheathed on the thin and flexible tube. The outer wall of a thin needle tube of the needle head has a thin insulating coating. A thin conductive coating is arranged outside an electric insulation layer. The thin needle tube and the conducting layer at the needle tip position constitute a pair of electrodes. An indicator light circuit with a battery is arranged on the needle head. The two electrodes are connected with the indicator light circuit by conductors. After the needle head punctures the vascular wall for the upper layer and a needle tip enters into a blood vessel, the utility model can send out signals, the condition that the needle tip has entered into the blood vessel can be indicated, and the utility model can avoid that the needle head continues to puncture the vascular wall for the lower layer.
