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.
Claims20
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, the needle hub including a front end side and a base end side on opposite axial sides of 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 tubular needle projecting away from the needle hub on the front end side of the flange;
- 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;
- and
- the protector being pivotably mounted on an axle part positioned on the base end side of the flange so that the protector pivots on the axle part about the pivot axis.
A packaged article comprising:
- an intradermal needle;
- and
- a container in which is positioned the intradermal needle,
- the intradermal needle including 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;
- and 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 on the base end side of the flange so that the protector pivots on the axle part about the pivot axis, and
- the container including a bottom face configured so that an inner diameter of the container is nearly equal to an outer diameter of the flange constituting the enlarged diameter part, the intradermal needle being positioned in the container with the protector in the open position.
An injection device comprising:
- an intradermal needle;
- and
- a syringe attached to the intradermal needle in a detachable manner,
- the intradermal needle including 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;
- and 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 on the base end side of the flange so that the protector pivots on the axle part about the pivot axis.
