Abstract:
1. A needle assembly comprising: needle hub having opposite proximal and distal ends and a passage extending between said ends; flexible wings projecting transversely from a portion of said needle assembly in proximity to said hub, said wings, in an unbiased condition, substantially defining a plane; a needle cannula having a proximal end and a distal end and a lumen extending between said ends, said needle cannula having a proximal portion adjacent said proximal end of said needle cannula, said proximal portion of said needle cannula being secured in said passage of said needle hub, said needle cannula further having a distal portion adjacent said distal end of said needle cannula and externally of said needle hub, said distal portion of said needle cannula being aligned at an angle to said proximal portion of said needle cannula, said distal end of said needle cannula being on first side of said plane defined by said unbiased wings, said proximal and distal portions of said needle cannula defining a plane aligned substantially normal to said plane defined by said unbiased wings; and a safety shield hinged to said hub at a hinge location disposed on a second side of said plane of said unbiased wings and opposite from said first side of said plane, said safety shield being hinged for movement about an axis substantially perpendicular to the plane defined by said proximal and distal portions of said needle cannula from an open position where said distal end of said needle cannula is exposed to a closed position where said distal end of said needle cannula is substantially covered by said safety shield.
