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.
Claims6
A shield for protecting the needle of a syringe, said shield comprising:
- a connector for connecting the shield to the base of needle, said connector being generally annular and adapted to slip fit over the base of the needle;
- a pair of protective arms hingedly mounted upon said connector;
- biasing means normally biasing said arms to a closed position wherein said arms are adjacent to one another to form an enclosure for enclosing said needle of said syringe, said protective arms being manually displaceable with respect to one another against the bias of said biasing means to expose said needle;
- said protective arm and said connector being integrally formed as a one-piece unit, and said biasing means being defined by a notch formed between said protective arm and said connector, also as part of said one-piece unit, to form a resilient hinge between said protective arms and said connector.
