ABSTRACT:
A shield for protecting the needle of a syringe. The shield has a connector for connecting the shield to the syringe with the connector preferably being generally annular and adapted to slip fit over the base of the needle, unless the syringe is formed with a needle, then the connector body would fit over the end of the syringe. The shield includes at least one protective arm hingedly mounted upon the connector and pivotable between first and second positions. The first position is the normal position wherein the protective arm conceals the needle and the second position corresponds to the protective arm being pivotally displaced to expose the needle. The arm is automatically biased to the first position so that the needle is normally and automatically concealed.
