Abstract
Provided are an intradermal needle having a protector that is movable from an open position near a needle hub to a closed position where a needle tip is covered, a packaged article, and an injection device. The protector has an arm that is supported in a freely pivotable manner by an axle pin positioned on the base end side of the wide diameter part of the intradermal needle, and a lid supported by the arm. With the axle of pivoting of the protector positioned near the needle hub, the lid may be housed compactly near the needle hub when the protector is in the open position.
Claims24
An intradermal needle comprising:
- a tubular needle having a needle tip configured to puncture a living body;
- a needle hub supporting the tubular needle and possessing a central axis extending through the needle hub;
- a flange fixed to and extending outwardly from the needle hub so that the flange is an enlarged diameter part of the needle hub;
- the needle hub including a first member that extends in a distal direction from the flange to a distal-most end of the needle hub, the needle hub also including a second member that extends in a proximal direction from the flange to a proximal-most end of the needle hub;
- the tubular needle projecting in the distal direction away from the needle hub;
- a pivotable protector that is pivotable about a pivot axis perpendicular to the central axis of the needle hub to pivot from an open position in which the needle tip is exposed and uncovered by the protector to a closed position in which the needle tip is covered by the protector;
- the protector being pivotably mounted on an axle part positioned proximal of the flange so that the protector pivots on the axle part about the pivot axis, the pivot axis being axially spaced from the flange in the proximal direction and passing through the second member;
- the pivot axis passing through the second member, the pivot axis passing through the axis of the needle hub or being adjacent the axis of the needle hub;
- the axle part being a first axle part and including a second axle part, the protector including two arms that each extend from a respective one of the first and second axle parts, and a lid supported by the arms, the needle hub being positioned between the two arms, and the lid being supported by the two arms, and
- a distance between the two arms is smaller than a diameter of the enlarged diameter part.
