Abstract
A syringe assembly is disclosed which includes a syringe body defining a first fluid reservoir and a fluid outlet. A plunger assembly includes a plunger rod and a plunger. The plunger is supported on a distal end of the plunger rod and defines a second fluid reservoir. The plunger is movable within the syringe body from a retracted position to an advanced position to eject fluid from the first fluid reservoir. A piercing member is supported on a distal end of the plunger rod within the second fluid reservoir. The piercing member is movable to pierce the plunger to eject fluid from the second fluid reservoir when a predetermined force is applied to the plunger in the advanced position.
