Abstract
Embodiments of the present safety needle assembly include a slidable needle shield. Digital pressure applied to a leaf spring retention latch removes a compressive force from a biasing member and automatically moves the needle shield from a ready-to-use configuration to a protected configuration in which the needle shield covers the sharp needle tip. In the protected configuration the needle shield is prevented from sliding proximally along the needle a sufficient distance to expose the needle tip.
