Abstract
To develop a medical needle having a small protecting member that is not separate from a needle and a hub, is not obstructive to the performer during use, and is easy to switch from being in a usable state to being in a protective state.A pair of wings are pivotally connected to a hub provided at the tail end of a needle, the wings being provided on both sides of the axis of the needle; one or two or more link members are connected to the tip of each of the wings with joints interposed therebetween; the tips of the link members are pivotally connected to a cylindrical protecting member slidably fitted onto the needle; and, when the protecting member is moved toward the tip of the needle, the wings and the link members move in such directions as to become parallel to the needle while the protecting member comes to cover the tip of the needle, whereby the above object is solved.
