The present invention provides a transfusion needle with security, comprising a main body and a safety sheath. The main body is provided at the side thereof with a needle wing, and connected at one end thereof with a needle head. The front-end side and the rear-end side of the safety sheath are provided with an inclined opening and a depressed opening, respectively. The needle head is protruded out of the safety sheath when the needle wing located within the inclined opening before the transfusion needle is used, while the needle head is covered within the safety sheath when the needle wing pulled back to the depressed opening from the inclined opening after the transfusion needle has been used. The needle head may be retrieved into the safety sheath after the transfusion needle has been used, so as to avoid the medical personnel stabbed by the used needle head.
