摘要：
A needle assembly includes a needle and a needle shield device. The needle shield device includes an inner shield connectable to at least one a base and a fluid connector connectable to the base, and an outer shield fixedly connected to the opposing end the needle and displaceable relative to the inner shield between a first position, in which the sharpened end of the needle is exposed outside the inner shield, and a second position, in which the sharpened end of the needle is shielded by the inner shield. Interaction between portions of the inner and outer shields during or after proximal displacement of the outer shield from the first position to the second position automatically releases or permits release of the inner shield from connection to the at least one of the base and the fluid connector.
