Abstract
A needle assembly includes a housing having proximal and distal ends, an IV cannula projecting distally from the housing, and an IV shield having an engagement. The housing has a shield seat and the IV cannula has a distal tip. The IV shield has a pre-use position where the IV shield covers the distal tip of the IV cannula and the engagement is disengaged from the shield seat, and a use position where the engagement is engaged with the shield seat and the IV shield is adapted to move between a non-shielded position, in which the distal tip is exposed, and a shielded position, in which the distal tip is shielded by the IV shield.

A needle assembly comprising:
- a housing having proximal and distal ends;
- a cannula having an IV end projecting distally from the housing and a non-patient end projecting proximally from the housing;
- and
- a single IV shield comprising a pair of spaced-apart sidewalls that define a space for receiving a portion of the IV end of the cannula, the IV shield pivotally secured to the housing and having a pre-use position, in which the IV shield covers a portion of the IV end of the cannula, and a use position, in which the IV shield is adapted to move between a non-shielded position and a shielded position,
- wherein each of the sidewalls includes a pair of projections adapted to temporarily hold the distal end of the housing therebetween when the IV shield is in the pre-use position.
