Safety pen needle assembly having shield for non-patient end

A safety pen needle assembly comprising:

• a hub having a tubular body with a proximal end, a distal end, a channel defined interiorly of said body and extending between said proximal and distal ends, and a wall disposed within said body to extend transversely at least partially across said channel;
• a needle extending through said channel having a distal end, formed for insertion into a patient, and a proximal end, wherein said needle is fixed to said hub with said distal end being located distally of said wall and said proximal end being located proximally of said wall;
• a shield disposed proximally of said wall and at least partially within said hub;
• a biasing means disposed to urge said shield proximally from a first position to a second position;
• and,
• at least one pivoting locking finger on said body of said hub, said pivoting locking finger being deflectable from a first state to a second state, wherein, in said first state, said pivoting locking finger interferingly engages said shield so as to restrict proximal movement thereof, said pivoting locking finger in said first state retaining said shield in said first position with said proximal end of said needle being exposed, and, wherein in said second state, said pivoting locking finger does not interferingly engage with said shield so as to permit said shield to be urged proximally to said second position by said biasing means, said shield covering said proximal end of said needle in said second position.
