Automatically operable safety shield system for syringes
First Claim
1. An automatically operable safety shield system for use with a syringe, said safety shield system comprising:
- an inner holder having proximal and distal portions and defining an enclosure into which said syringe may be inserted;
an outer shield having proximal and distal portions, mounted outwards from said inner holder and being axially movable relative to said inner holder between retracted and extended positions;
a spring positioned between a first detent on said inner holder and a second detent on said outer shield, and urging said outer shield to its extended position;
said inner holder having at least one first opening and said outer shield having at least one first stop member, said first stop member being engageable with said first opening when said outer shield is in said retracted position;
said inner holder having distal to said first opening at least one first indentation, said first stop member being engageable with said first indentation when said outer shield is in said extended position; and
a trigger positioned within said inner holder and axially movable relative to said inner holder such that it can contact said first stop member when it is engaged with said first opening and disengage said first stop member from said first opening, allowing said spring to move said outer shield to said extended position.

Abstract
An automatically operable safety shield system for use with a syringe, the safety shield system including an holder having proximal and distal portions and defining an enclosure into which the syringe may be inserted, an outer shield having proximal and distal portions, mounted outwards from the inner holder being axially movable relative to the inner holder between retracted and extended positions, a spring positioned between a first detent on the inner holder and a second detent on the outer shield, and urging the outer shield to its extended position, the inner holder having at least one first opening and the outer shield having at least one first stop member, the first stop member being engageable with the first opening when the outer shield is in the retracted position, the inner holder having distal to the first opening at least one first indentation, the first stop member being engageable with the first indentation when the outer shield is in the extended position.

4. An automatically operable safety shield system, comprising:
-
a syringe comprising a barrel, a needle, a piston and a plunger rod movable within said barrel, said plunger rod having a protrusion;
an inner holder having proximal and distal portions and defining an enclosure into which said syringe may be inserted;
an outer shield having proximal and distal portions, mounted outwards from said inner holder and being axially movable relative to said inner holder between retracted and extended positions;
a spring positioned between a first distal detent on said innerholder and a second distal detent on said outer shield, and urging said outer shield to said extended position;
said inner holder having at least one first opening and said outer shield having at least one first stop member, said first stop member being engageable with said first opening when said outer shield is in said retracted position;
said inner holder having distal to said first opening at least one first indentation, said first stop member being engageable with said first indentation when said outer shield is in said extended position; and
said syringe being operationally coupled to said inner holder and outer shield such that axial movement of said plunger rod protrusion relative to said inner holder causes said plunger rod protrusion to contact said first stop member when it is engaged with said first opening and disengage said first stop member from said first opening, allowing said spring to move said outer shield to said extended position. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
