The present invention addresses the problem of simplifying the structure and reducing the number of parts by having wings also serve as a safety cover, and of eliminating the inconvenience of mutual interference between the wings and safety cover. The solution is a winged injection needle 1 comprising an injection needle main body 2, a base 3 that supports the base end of the injection needle main body 2 and wings 4 that protrude from the base 3 toward the left and right sides to function as handles, the wings 4 being constructed with plate members that are freely foldable through hinge sections 4a, 4b, 4c, so that in the folded state, they protrude from the base 3 toward the left and right sides to function as handles, while in the expanded state, they extend from the base 3 along the injection needle main body 2 toward the leading edge of the injection needle to function as a safety cover that covers the injection needle main body 2.【課題】羽根部を安全カバーに兼用して構造の簡略化や部品点数の削減を図るとともに、羽根部と安全カバーが互いの操作を邪魔するような不都合も解消する。【解決手段】注射針本体2と、該注射針本体2の基端部を支持する基部3と、該基部3から左右両側方に突出して持ち手として機能する羽根部4とを備える羽根付き注射針1であって、羽根部4は、ヒンジ部4a、4b、4cを介して折り畳み自在な板状部材を用いて構成され、折り畳み状態では、基部3から左右両側方に突出して持ち手として機能する一方、展開状態では、基部3から注射針本体2に沿って注射針先端側に延出して注射針本体2を覆う安全カバーとして機能する。【選択図】図1
