A medical needle includes a needle portion () having a needle tip on a distal end, a case () configured to be capable of accommodating the needle portion that can be exposed from the distal end side, a movement mechanism () for moving the needle portion inside the case, and a movement restricting portion () that restricts the needle tip accommodated in the case from moving in a direction opposite to a moving direction of the needle portion. The movement restricting portion maintains the needle tip accommodated in the case such that the needle tip can come into contact with an inner face of the case to restrict the movement of the needle tip in the opposite direction.

Medical needle

In a safety apparatus for medical needles, when leg portions are extended from a first folded position to a second extended position, a distal end of a needle is introduced into a space of a shield member connection hub, and a first blocking wall and a second blocking wall overlap so as to block the cross section of the space to form a double blocking wall and blocks the cross section of the space. The double blocking wall is capable of preventing the distal end of the needle from moving downward from the double blocking wall and preventing the distal end of the needle from being exposed to the outside of the apparatus.
