A winged needle used in an internal fistula need set is made of an elastic material in one piece, having a hub for holding a needle, two wings respectively connected to two opposite sides of the hub and a protective cover connected to the front end of the hub and elastically movable relative to the hub between an open position where the needle is completely exposed for use to inject medicine or to withdraw the blood and a closed position where the needle is shielded by the protective cover to prevent the operator from being accidentally stabbed by the needle during needle collection. Thereby, the winged needle hub of the invention can achieve the advantages of simplified structure, convenient operation and improved safety of the needle.本發明有關於一種用於內廔管翼狀針之針座，該針座使用彈性材質以一體成型的方式所製成，其包含有一導管、二翼片及一護蓋，其中的導管用來固定一針體，該二翼片連接於導管之二相對側，至於護蓋則是連接於導管之前端且能相對導管於一開放位置與一蓋合位置之間彈性擺動，當護蓋位於開放位置時，針體會完全顯露在外，此時即可利用針體進行注射或抽血動作，當護蓋位於蓋合位置時，針體會被護蓋所遮蓋住，以防止操作人員在收針時被針體給意外刺傷。藉此，本發明之針座可達到簡化結構、操作方便及提升收針安全性的效果。
