Abstract:
1. A retractable safety needle apparatus comprising: a needle holder having an open proximal end, a distal end and a substantially tubular side wall extending between said ends, a distal end wall extending inwardly from said tubular side wall at said distal end of said needle holder and having a needle aperture extending therethrough, an actuating aperture formed through said side wall of said needle holder; a needle assembly non-rotatably disposed in said needle holder for axial movement between a proximal position and a distal position, said needle assembly having a distal needle cannula projecting through said needle aperture of said needle holder when said needle assembly is in said distal position, said distal needle cannula being disposed entirely within said needle holder when said needle assembly is in said proximal position; a spring extending between said distal wall of said needle holder and a portion of said needle assembly for biasing said needle assembly to said proximal position; and an actuator movable with said needle assembly and deflectable relative to said needle holder, said actuator being releasably engaged in said actuating aperture of said needle holder when said needle assembly is in said distal position, said actuator being selectively deflectable out of engagement with said needle holder permitting said spring to propel said needle assembly to said proximal position.
