This invention provides an improved infusion set, belonging to the field of medical auxiliary devices, including an infusion tube, an infusion assembly, and a storage assembly. One end of the infusion tube is connected to a puncture device, and a drip chamber is provided on the surface of the infusion tube. The other end of the infusion tube is connected to a flexible tube, on the surface of which an infusion needle is slidably mounted. A needle wing is connected to the tail end of the infusion needle. During puncture, the infusion needle is inserted into the blood vessel, and the flexible tube enters the blood vessel simultaneously. By pulling the needle wing, the infusion needle moves on the surface of the flexible tube and exits from the blood vessel, leaving the flexible tube in place. This infusion method replaces leaving a steel needle inside the blood vessel, reducing drug extravasation, facilitating patient hand movement, and preventing puncture wounds to blood vessels.
