Abstract
A medical needle device includes a winged shield () having a substantially cylindrical shaped shield cylinder () and wings () connected to the front end side thereof, a needle base () inserted in the shield cylinder (), and a needle (). The wings have wing projections () and the shield cylinder has through holes () on the wall thereof. By overlaying the wings along the side surface of the shield cylinder, each of the wing projections can be inserted into the inner cavity of the shield cylinder via the through hole. Thereby, without requiring a special operation in the sticking operation, each of the wing projections can prevent the needle base from moving in the axial direction and can hold the needle base in the shield cylinder reliably in a state in which the needle protrudes from the front end of the shield cylinder by a predetermined length.
