ABSTRACT:
The safety device of the instant invention is equipped with a fluid absorbable material at the portion of the sheath that meets the tip portion of the needle so that, as the sheath is pivoted to a position in substantial alignment with the needle, whatever fluid that has been collected at the needle is absorbed before the needle is fixedly retained by a locking mechanism, either integrated within the needle sheath or to the base and lower portion of the needle sheath, to thereby prevent splattering or aerosolization of contaminated fluid into the environment.
