Abstract
A safety needle assembly includes a housing and a cannula hub connected within a side wall of the housing, a needle connected to the cannula and extending from the cannula hub outward from a proximal end of the housing, and a spring connected with the housing. The assembly includes a barrel connected with the spring and at least partially contained within the housing to least partially cover the cannula hub. The barrel is configured for moving, sliding, traveling, activating, relocating, or transitioning from a first mode in which the barrel is securely retracted and locked at least partially within the housing and the needle extends through an aperture of the barrel and the proximal end of the housing, to a second mode in which the barrel extends from the proximal end and beyond the needle.
