Abstract
A syringe needle shield that includes a first part and a second part. The first part is connected to the second part by a pivotable first connection portion. The second part is pivotable on the first connection portion toward the first part, and a needle hub is clamped between the first and second parts. The first and second parts are securely connected to each other by the first snapping portion which cannot be unlocked from each other. The first part is connected to a needle shield by a flexible plate. The shield receives a push force from its back so as to move from a first position to a second position. When the shield is located at the second position, a restriction portion is fixedly engaged with an engaging portion.
Claims7
A syringe needle shield comprising:
- a first part and a second part, a first side of the first part connected to a first side of the second part by a pivotable first connection portion, the second part being pivotally movable toward the first part on the first connection portion;
- a first snapping portion including a recess inside of the first part and a hook inside of the second part, the hook being fixedly connected with the recess and cannot be separated from the recess when the second part is pivotally moved toward the first part;
- a first room and a second room respectively defined in the first part and the second part, wherein when the first part is connected to the second part by the first snapping portion, the first room and the second room together define a chamber, the chamber being vertically defined through a top and a bottom of each of the first part and the second part, the chamber adapted to accommodate and restrict a needle hub of a syringe;
- a first groove and a second groove respectively defined inside of the first part and the inside of the second part, and in communication with the first room and the second room, wherein when the first part is connected to the second part by the first snapping portion, the first groove and the second groove together define an annular groove inside of the chamber, the annular groove adapted to accommodate and restrict a flange of the needle hub;
- a flexible plate connected between an underside of a shield and the first part, the shield pivotally movable from a first position to a second position;
- and
- a positioning device having a first positioning portion and a second positioning portion, the first positioning portion located at the second part, and the second positioning portion connected to the shield, the first positioning portion and the second positioning portion respectively including a restriction portion and an engaging portion, such that when the shield is located at the second position, the restriction portion is engaged with the engaging portion.
