A safety needle assembly is provided herein which includes a hub； a needle fixed to the hub； a first shield having a tubular body at least partially encircling a portion of the needle, wherein in an initial state, the first shield extends from the hub； a second shield having a tubular body at least partially encircling a portion of the needle； a biasing element disposed to urge the second shield distally towards a distal end of the needle； and, a releasable retaining arrangement for releasably retaining the second shield in a first state. Upon a predetermined extent of proximal movement of the first shield relative to the hub, the second shield is released to a second state in which the distal end of the needle is covered. Advantageously, two shields are provided for at least partially covering a needle with one of the shields acting as a trigger.
