Abstract
A winged needle with which the needle can be safely exposed and covered. The winged needle comprises a base into which the needle is rooted, wings which can be folded to cover the needle, sheath-portion of the wings which surrounds the needle on all sides when the wings are folded, and a coupling device which couples the wings. This structure enables a user to handle the winged needle from the base side without having his hand face the needle tip, significantly reducing the possibility of puncturing the user's hands.
