摘要：
A safety pen needle assembly (10) is provided herein which includes a hub(12), a needle (14) fixed to the hub having a distal end, formed for insertioninto a patient,and a proximal end, a shield (18), a biasing (16) means disposed to urge theshield from afirst position to a second position, and, at least one adjustable (34) tab orlocking finger onthe hub, the tab or finger being adjustable from a first state to a secondstate. With the tab orfinger being in a first state, the tab or finger interferingly engages theshield so as to restrictmovement thereof. The tab or finger in the first state retains the shield inits first positionwith the proximal end of the needle being exposed. With the tab or fingerbeing in the secondstate, the tab or finger does not interferingly engage with the shield. Assuch, the shieldis permitted to be urged proximally to the second position by the biasingmeans In the secondposition, the shield covers the proximal end of the needle. Advantageously,with thesubject invention, a mechanism is provided for shielding a proximal, or non-patient, end of apen needle, particularly after use.
