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.

A shield for protecting the needle of a syringe said shield comprising:
- a connector for connecting the shield to a syringe;
- at least one protective arm hingedly mounted upon the connector, the protective arm being pivotable between first and second positions, the first position being the normal position wherein the protective arm conceals the needle, the second position corresponding to the protective arm being pivotally displaced to expose the needle;
- a biasing bar for automatically biasing the protective arm to the first position, the biasing bar extends between the connector and the protective arm;

A shield for protecting the needle of a syringe said shield comprising:
- a connector for connecting the shield to a syringe;
- at least one protective arm hingedly mounted upon the connector, the protective arm being pivotable between first and second positions, the first position being the normal position wherein the protective arm conceals the needle, the second position corresponding to the protective arm being pivotally displaced to expose the needle;
- a biasing bar extending between the connector and the protective arm for normally biasing said arm to a closed position wherein said arm conceals said needle, said protective arm being manually displacable with respect to said syringe to an open position to expose said needle;
- said biasing bar biases against said protective arm such that said protective arm automatically travels from the open position to the closed position and is unhindered throughout its travel from the open position to the closed position.
