Needle protection assembly
First Claim
Patent Images
1. A needle protection assembly, comprising:
- a support at least partially supporting a needle, the needle defining a longitudinal axis;
a needle shield having a distal end and a proximal end, the needle shield moveable relative to the support from a first position in which at least a portion of the needle is exposed, to a second position in which the needle is fully shielded;
a locking element separate from the needle shield, the locking element disposed within the support, wherein a skewable portion of the locking element is positioned parallel to the longitudinal axis of the needle when the needle shield is in the first position, the locking element having an asymmetrical outer flange located at a proximal end thereof, a longitudinal cut being formed in a distal end of the locking element which extends proximally therefrom; and
an urging means for biasing the needle shield from the first position to the second position, the urging means extending from the proximal end of the needle shield toward the proximal end of the locking element,wherein, with the needle shield in the second position, the skewable portion of the locking element cants outwardly to remain skewed relative to the longitudinal axis of the needle, such that the distal end of the skewed locking element engages the proximal end of the needle shield to inhibit movement of the needle shield from the second position to the first position.

Abstract
The application relates to a needle protection assembly (1) comprising: —a supporting element (18) and a needle shield (8), —one locking element (20) located within said needle protection assembly (1) and not accessible to the user, —urging means (24) for displacing said needle shield (8), —a peg (19) located on said supporting element (18) or on said needle shield (8), and a cam (9) located on said needle shield (8) or on said supporting element (18), and—said locking element (20) is not formed by said peg (19) and cam (9). The respective longitudinal axis of the needle shield (8) and of the locking element (20) are merged when said needle shield (8) is in its before use or in use positions, and they form an angle (a) when said needle shield (8) is in its after use position.
