Abstract:
1. A safety winged needle structure, comprising: a protective casing and an accommodating body disposed in the protective casing, the accommodating body having a sliding member slidably movable within the protective casing, a neck portion extending from the sliding member, and a pushing portion attached to the neck portion and defining a top of the accommodating body, the pushing portion including two sides, and wherein a needle is attached to the accommodating body, the protective casing having at least one sliding slot disposed on a sidewall of the protective casing, a first position where the needle is shielded by the protective casing and a second position where the needle is exposed out of the protective casing, and two wings extending laterally from the protective casing, one of the wings having a first positioning structure, wherein the first positioning structure is a lateral edge of the wing; wherein when the accommodating body is moved within the protective casing to the second position, the two wings are configured to be moved upwards to a side of the protective casing and are pinched together over the sliding slot, thereby positioning the first positioning structure behind the sides of the pushing portion and preventing the accommodating body from sliding back from the second position.
